Part TECHNICAL FIELD: The present disclosure relates to portable fluid containers and container assemblies, in particular portable fluid containers and container assemblies suitable for containing and dispensing fluids, such as volatile fluids. Part BACKGROUND: Portable fluid containers are often used in the consumer market to transport and dispense fluids. Such containers are typically blow molded and are typically provided with one or more handles for carrying and manipulating the containers. However, such containers may be unwieldy, especially when filled with liquid. The positioning and/or orientation of these handle(s) on the container may contribute to the unwieldiness of the container. The number of handle(s) provided is typically limited and the handle(s) are not typically ergonomically oriented, which may result in reduced control and an awkward dispensing process when a user attempts to maneuver the container using the handle(s). It is also desirable to simplify the manufacture of such containers, in order to increase quality and reduce costs. These handle(s) are typically molded into the container material during the manufacturing (typically blow molding) process. The container quality may increase and the container cost may decrease if the handle(s) did not need to be formed in the blow molding process. Conventional containers are typically provided with one opening for both receiving and dispensing fluids, but not separate openings for each. Some fluid containers, which may be designed for certain types of fluids, may be subject to regulatory constraints. For examples, portable fuel containers may be regulated for safety and/or environmental concerns. Such regulations may require, for example, sturdy handles, proper coloring and/or features to reduce spilling of fluids. Conventional fuel containers have met such requirements by using a relatively simple container design. However, such products may be awkward, inconvenient and/or unwieldy to manually maneuver, making it difficult to manage and/or control the dispensing of fluids. Such containers may perform relatively poorly in various fuelling applications (e.g., pouring fuel into a tank), and when used by particular users that may lack manual strength and/or dexterity (e.g., older users). Issues that may be improved upon include, for example, ergonomic container construction and operation, container storage, transportation convenience and stability, ease of use, pouring convenience, such as improved control on the dispensing activation and flow rate, among others. Part SUMMARY: In some example aspects, the present disclosure provides an attachment for communication of fluid from a fluid source, the attachment may include: a body defining a receiving end for receiving fluid from the fluid source and a distal end for dispensing fluid from the attachment; a first fluid passage defined in the body permitting fluid flow through the body at least to the distal end; at least one valve engaging portion housed in the body; wherein the attachment comprises at least two telescoping portions, wherein motion of the telescoping portions relative to each other brings the at least one valve engaging portion towards the receiving end. In some examples, the attachment may include a second fluid passage defined in the body permitting fluid flow through the body at least from the distal end. In some examples, the at least one valve engaging portion may include at least one projection. In some examples, the body may include the at least two telescoping portions, and motion of the telescoping portions relative to each other comprises shortening of the body. In some examples, the attachment may include a connecting member for attaching the attachment to the fluid source. In some examples, the body and the connecting member may include the at least two telescoping portions, and motion of the telescoping portions relative to each other comprises bringing the body closer to the fluid source. In some examples, the distal end may be configured as a spout. In some examples, the first fluid passage and the second fluid passage may be generally co-axial. In some examples, the first fluid passage may be configured for liquid fluid flow and the second fluid passage may be configured for vapor fluid flow. In some examples, motion of the telescoping portions relative to each other may be actuated by a cable. The cable may be connectable to a trigger remotely located from the attachment for actuating motion of the telescoping portions relative to each other. In some examples, the attachment may include a removable dispenser member connected to the distal end for dispensing fluid from the attachment. In some examples, the body may include a removable dispenser member defining the distal end. In some examples, one of the at least two telescoping portions may include a removable dispenser member defining the distal end. In some examples, the removable dispenser member may be configured as a spout tip. In some examples, the attachment may include a protrusion extending from at least a portion of an outer surface of the body near the distal end, the protrusion being configured to come into close contact with an outer surface of a fluid destination when the distal end is inserted into an inlet of the fluid destination. The protrusion may include an extended surface. In some examples, the motion of the telescoping portions relative to each other may be effected by engagement of the protrusion with an inlet opening of the fluid destination. In some examples, motion of the telescoping portions relative to each other may be actuated by a cable, wherein the protrusion may be movable between an enabling position and a disabling position, and actuation by the cable may be enabled when the protrusion is in the enabling position and disabled when the protrusion is in the disabling position. In some examples, when the protrusion comes into close contact with the outer surface of the fluid destination, the protrusion may be held in the enabling position. In some example aspects, the present disclosure provides an attachment for communication of fluid from a fluid source, the attachment may include: a body defining a receiving end for receiving fluid from the fluid source and a distal end for dispensing fluid from the attachment; a first fluid passage defined in the body permitting fluid flow through the body at least to the distal end; at least one valve engaging portion housed in the body; wherein the at least one valve engaging portion is configured to engage a valve of the fluid source, and motion of the at least one valve engaging portion towards the fluid source causes the valve to open. In some examples, the attachment may include a second fluid passage defined in the body permitting fluid flow through the body at least from the distal end. In some examples, the at least one valve engaging portion may include at least one projection. In some examples, the attachment may include a connecting member for attaching the attachment to the fluid source. In some examples, motion of the body and the connecting member relative to each other may cause the motion of the at least one valve engaging portion towards the fluid source. In some examples, the distal end may be configured as a spout. In some examples, the first fluid passage and the second fluid passage may be generally co-axial. In some examples, the first fluid passage may be configured for liquid fluid flow and the second fluid passage may be configured for vapor fluid flow. In some examples, the attachment may include a removable dispenser member connected to the distal end for dispensing fluid from the attachment. In some examples, the body may include a removable dispenser member defining the distal end. In some examples, the removable dispenser member may be configured as a spout tip.

In some examples, the source connector may include: a second fluid passage defined within the body permitting fluid flow at least between the connection end and the attachment end; and a second valve for controlling flow of the fluid through the second fluid passage, the second valve being biased towards a valve closed configuration in which fluid flow through the second fluid passage is inhibited; and the attachment may include: a second fluid passage defined in the body permitting fluid flow through the body at least from the distal end; wherein motion of the at least one valve engaging portion towards the attachment end causes the second valve to be reconfigured to a valve opened configuration, thereby permitting fluid communication between the second fluid passages of the respective attachment and source connector. In some examples, the first valve may be biased towards the connection end to define the valve closed configuration. In some examples, the first valve may be biased towards the connection end to define the valve closed configuration of the first valve and the second valve is biased towards the attachment end to define the valve closed configuration of the second valve. In some examples, the first valve and the second valve of the source connector may be moveable at least partially from their respective valve closed configurations to respective valve opened configurations by motion of the first valve towards the attachment end, the motion of the first valve being interconnected with motion of the second valve. In some examples, motion of the first valve toward the attachment end simultaneously, nearly simultaneously or with some slight delay may unseat the second valve thereby moving the second valve to the valve opened configuration. In some examples, the second valve may be seated against the first valve when both valves are in their respective valve closed configurations. In some examples, for at least a portion of the motion of the first valve towards the attachment end, the second valve may be carried along by the first valve towards the attachment end before the second valve may be moved to the valve opened configuration. In some examples, the first fluid passage and the second fluid passage of the connector may be generally co-axial, and the first fluid passage and the second fluid passage of the attachment may be correspondingly generally co-axial. In some examples, the first fluid passages of the attachment and the connector may be configured for liquid fluid flow and the second fluid passages of the attachment and the connector may be configured for vapor fluid flow. In some examples, the first valve and the second valve may be independently biased towards their respective valve closed configuration. In some examples, the first and second valves may be biased toward their respective valve closed configurations by respective independent first and second biasing members. In some examples, the first and second biasing members may include compression springs. In some examples, the first valve may be biased toward the valve closed configuration by a first biasing member. In some examples, the first biasing member may include a compression spring. In some examples, the first valve, when in the valve closed configuration, may define a substantially planar surface. In some examples, the first and second valves, when in their respective valve closed configurations, may define a substantially planar surface. In some examples, the source connector may be configured as a container cap. In some example aspects, the present disclosure provides a container assembly that may include: any of the systems described above; and a fluid container as the fluid source.

In some examples, the body may include an attachment end portion defining the attachment end and a movable end portion telescopically engaged on said attachment end portion, and wherein said valve engaging portion is disposed on said movable end portion, such that motion of the movable end portion towards the attachment end of the body causes said valve engaging portion to move to a valve opening position for opening the valve of the fluid source. In some examples, the attachment may include a second fluid passage defined in the body for permitting fluid flow through the body at least from the distal end. In some example aspects, the present disclosure provides a connection system that may include: a source connector having a fluid passage and a source connecting portion for connecting the source connector to a fluid source; a valve mechanism for controlling flow of fluid through the fluid passage; and a fluid transfer attachment having a fluid passage; wherein said source connector has an attachment-receiving portion for receiving and/or retaining the fluid transfer attachment; and wherein said valve mechanism is opened when said fluid transfer attachment is received by said attachment-receiving portion, to enable fluid communication between the fluid passage of the source connector and the fluid passage of the fluid transfer attachment.

Part DETAILED DESCRIPTION: The present disclosure describes examples of a portable fluid container assembly, a portable fluid container, and components thereof. Throughout this disclosure, it should be understood that many features described with respect to a container may also apply to a container assembly and vice versa. The portable fluid container assembly may provide one or more of: a container with or without a permeation barrier treatment; an enclosure or frame attachable to the container or container assembly, where the enclosure or frame may include one or more handles (which may be conveniently located for a user to maneuver the container assembly), and where the enclosure or frame may provide features for joining two or more container assemblies together (e.g., for transport and/or added stability); a dispenser (e.g., an attachment, a fluid transfer attachment, a pouring spout or other suitable means), which may be an openable and closeable dispenser (e.g., having a removable cap or a controllable valve) which may provide passive vapor recovery features; at least one remotely-located trigger for controlling the flow rate of fluid from the container assembly (e.g., by controlling operation of the dispenser, such as by controlling opening and closing of a dispenser cap or valve) and to help prevent unintentional spillage; and a separate opening for filling the assembly. This separate opening may be useful in avoiding the need to replace or remove a dispenser (e.g., a spout) from a shared filling/dispensing opening when switching between filling and dispensing use. This may help to reduce contamination of the user's hand with the contained liquid (e.g., fuel) from handling a dispenser and may also help to reduce the introduction of contamination into the container itself, which can occur when a dispenser is removed and replaced. For example, during the refueling process of a conventional container, a dispenser is typically removed from the opening in order to allow filling of the container, and the dispenser may be set down on a convenient but potentially dirty surface. The dispenser may pick up contaminants and when replaced on the container (e.g., in preparation for dispensing from the container), any contaminant (e.g., dirt) on the dispenser may be introduced into the container and may thus contaminant the fluid contained within. In some examples, this separate opening may be designed to help accommodate conventional vapor recovery dispenser systems (e.g., when filling the container with a conventional vapor recovery nozzle, such as at a gas station). In some examples, a portable fluid container assembly may include an inner body for retaining a fluid, the inner body defining at least one opening for at least one of receiving and dispensing fluid; an enclosure at least partially enclosing the inner body, the enclosure including at least one handle for manipulating the assembly; and a cover for closing the at least one opening of the inner body, the cover may include at least one of a dispenser for dispensing fluid and a valve mechanism for controlling and regulating the flow of fuel either to or from the assembly. In some examples, the dispenser may be a dispensing tube or tubes for directing the flow of fluid from the portable fluid container assembly. In some examples, the dispenser may include a valve mechanism for controlling, regulating and directing the flow of fuel from the container. In some examples, a portable fluid container assembly may include an inner body for retaining a fluid, the inner body defining at least one opening for at least one of receiving and dispensing fluid; and an enclosure at least partially enclosing the inner body, the enclosure including at least one handle for manipulating the assembly. The portable fluid container assembly may include a cover for closing the at least one opening of the inner body, the cover including a dispenser for dispensing fluid. In some examples, the cover may include at least one closeable cover opening for receiving fluid. In some examples, the assembly may include a trigger for controlling fluid flow from the dispenser, the trigger being remotely located from the dispenser. In some examples, the assembly may include at least one mating member, which may include at least one interlocking or registration/locating feature (e.g., a projection and complementary recess), on the enclosure for joining the assembly to at least one other assembly. In some examples, the enclosure may include at least one window for viewing the inner body (e.g., to view the presence and/or level of any liquid contained inside and/or to view the color of the inner body). In some examples, the assembly may include at least one wheel attached or attachable to the enclosure for transporting the assembly. In some examples, the inner body may be blow-molded or rotation molded. In some examples, such as where the inner body is blow-molded or rotation molded, the inner body may be formed without any handles. Such a configuration may simplify the manufacturing process. One or more handles for maneuvering the assembly may be provided by the enclosure. In some examples, such as where the inner body is blow-molded or rotation molded, the inner body may have a curved base. Such a configuration may simplify the manufacturing process. The enclosure may provide a base for supporting inner body in an upright position when the assembly is upright. In some examples, the enclosure may form a stackable surface for stacking the assembly with at least one other assembly. This may be useful where the inner body has rounded or irregular surface(s) that render the inner body difficult or impossible to stack with other inner bodies. In some examples, the enclosure may be colored and the inner body may be uncolored. This may allow the inner body to be molded with a colorless material, which may simplify the manufacturing process and/or reduce manufacturing costs, while still complying with regulations requiring color identification of the assembly. The present disclosure also describes methods of manufacture. In some examples, a method for manufacturing a portable fluid container assembly includes providing an inner body for retaining a fluid, the inner body being formed without any handles; and attaching an enclosure to the inner body, the enclosure at least partially enclosing the body and including at least one handle for manipulating the assembly. In some examples, the inner body may be blow-molded or rotation molded. In some examples, the enclosure may be snap-fitted or welded to the inner body. In some examples, the present disclosure may provide a modular frame for a portable container, said modular frame comprising: a plurality of like frame members connectable one to another to form a full frame; wherein each frame member comprises a main body, a first connector and a second connector; and said first connector and said second connector are disposed in substantially opposed relation one from the other on said main body. In some examples, each said frame member may be integrally formed as a single piece of material. In some example aspects, the present disclosure may provide a modular frame for a portable container, said modular frame may include: a plurality of like frame members securable one to another to form a full frame; wherein each frame member comprises a main body; and wherein said plurality of like frame members are securable one to the other to form said full frame. In some examples, each said frame member may be integrally formed as a single piece of material. In some example aspects, the present disclosure may provide a cap for use with a portable container, said cap may include: a body; a first opening defined in said body; a valve mechanism for controlling flow of fluid through the first opening; a spout having a first fluid passage in fluid communication with said first fluid passageway; and a second opening defined in said body. In some example aspects, the present disclosure provides a frame for use with a container of a portable container assembly, said frame may include: a main body having a longitudinal axis and defining an internal opening for receiving said container therein; at least one handle; at least one support portion at each longitudinal end of the main body; wherein the support portions at each longitudinal end of the main body provide support surfaces at each longitudinal end of the main body to enable stacking of a plurality of said portable container assemblies along the longitudinal axis. In some example aspects, the present disclosure provides a frame for use with a container of a portable container assembly, said frame may include: a main body having a top end and a bottom end and defining an internal opening for receiving said container therein; at least one handle for permitting manual manipulation of said portable container assembly; at least one upwardly facing support portion; and at least one downwardly facing support engaging portion; wherein said at least one upwardly facing support portion and said at least one downwardly facing support engaging portion are horizontally aligned with one another, when each portable container of a plurality of stacked portable containers is vertically oriented, to permit stacking of a plurality of said portable container assemblies in top-to-bottom relation one on another. In some example aspects, the present disclosure may provide a frame for use with a container of a portable container assembly, said frame may include; a main body having a lateral axis and defining an internal opening for receiving said container therein; at least one handle; at least one laterally facing support portion; and at least one laterally facing support engaging portion; wherein said at least one laterally facing support portion and said at least one laterally facing support engaging portion are aligned with one another, to enable stacking of a plurality of said portable container assemblies along the lateral axis. In some example aspects, the present disclosure provides a frame for use with a container of a portable container assembly, said frame may include: a main body having a top end and a bottom end and defining an internal opening for receiving said container therein; at least one handle for permitting manual manipulation of said portable container assembly; at least one laterally facing support portion; and at least one laterally facing support engaging portion; wherein said at least one laterally facing support portion and said at least one laterally facing support engaging portion are horizontally aligned with one another, when each portable container of a plurality of stacked portable containers is horizontally oriented, to permit stacking of a plurality of said portable container assemblies in side-to-side relation one on another. In some example aspects, there is provided a portable container assembly comprising: a container; a frame mounted to the container, and having a longitudinal axis; a stabilizing protrusion oriented to protrude generally transversely to the longitudinal axis of the frame; and a cooperating recess for receiving the stabilizing protrusion of an adjacent similar portable container assembly, to thereby stabilize the two portable container assemblies. In some examples, the cooperating recess may receive the stabilizing protrusion of the adjacent portable container assembly in horizontally insertable relation. In some examples, the stabilizing protrusion may include one or more mating, complementary or interlocking fingers or fins. Examples of the present disclosure are now described with reference to the drawings. FIGS. 1A and 1B show an example of a portable fluid container assembly 1000 having a top end 1010 and a bottom end 1012 when the assembly 1000 is in an upright orientation, and defining a longitudinal axis “L”. In this example, the portable fluid container assembly 1000 may include a container or an inner body 100 for containing a fluid and an outer frame or enclosure 200 at least partially enclosing the inner body 100. The inner body 100 may include one or more openings (not shown) for receiving and dispensing fluid. In some examples, the inner body 100 may include one or more indentations 110 to enable gripping by a user (for example, as shown in FIG. 3), while other examples may not include any indentations 110 (for example, as shown in FIG. 2). The inner body 100 may be made of any suitable material, for example a moldable plastic. The inner body 100 may be a shape designed to avoid or decrease deformation of the inner body 100 as vapor pressure within the inner body 100 changes (e.g., increase or decrease of temperature may cause respective increase or decrease of vapor pressure, particularly where the fluid is a volatile fluid, such as a fuel). For example, the inner body 100 may have a cylindrical shape. In some examples, the inner body 100 may also include a rounded base. In some examples, the inner body 100 may include a concave or dished base, which may be convenient for a user's hand when tipping the assembly 1000, for dispensing fluid, for example. In some examples, the concave shape of the base may facilitate the stacking of container assemblies 1000 one on top of the other. For example, in two assemblies stacked one on top and one on the bottom, the concave shape of the base of the assembly 1000 on top may help to accommodate the cover or spout of the container assembly 1000 on the bottom. The inner body 100 may be formed using, for example, molding processes such as blow-molding or rotational molding. The inner body 100 may be manufactured without handles, which may simplify the molding process and/or avoid wasted material during molding compared to conventional containers. The inner body 100 may be manufactured without concern that the inner body 100 has to support itself in an upright position, since the enclosure 200 may serve to support the inner body 100 in an upright position. Thus, the shape of the inner body 100 (e.g., a cylindrical shape with a rounded base) may be relatively easy to manufacture using, for example, blow-molding techniques. Because the inner body 100 is provided with an enclosure 200, which may enclose all or a majority of the inner body 100, the inner body 100 may be manufactured with relatively few additives (e.g., pigments and/or UV protectors, according to safety regulations, for example), with the enclosure 200 instead providing any suitable color coding and/or UV protection, as appropriate, for example. The enclosure 200 may include one or more members that at least partially surround the inner body 100 and that may form one or more handles 205 for the portable fluid container assembly 1000. The enclosure 200 may also include one or more grips 210 that may cooperate with one or more respective indentations 110 to allow a user's hand to grip the portable fluid container assembly 1000, for example to enable transport or manipulation of the assembly 1000. The frame or enclosure 200 may also interconnect so as to be rigidly connected via one or more mating members 215, to enable two or more assemblies 1000 to be joined. The mating member(s) 215 of the assembly 1000 may include fingers, fins or protrusions designed to interlock or mate with complementary finger(s), fin(s) or protrusion(s), and/or complementary recess(es) in another assembly 1000. It should be understood that the mating member(s) 215 need not exactly match or mate with a corresponding feature on the other assembly 1000. For example, the mating member(s) 215 may loosely fit with a recess or complementary mating member(s) 215 of the other assembly. The mating member(s) 215 may join two or more assemblies 1000 together loosely (e.g., enabling some sliding or shifting relative to each other), but not necessarily in fixed relation. The mating member(s) 215 may be provided on more than one side of the enclosure 200 to enable joining of assemblies 1000 in multiple directions. The enclosure 200 may be made of any suitable material, for example a metal (e.g., aluminum) or plastic material. The enclosure 200 may be manufactured as a single piece (integrally formed) or may be assembled from multiple components. For example, the enclosure 200 may include one or more frames 220 (for example, as shown in FIGS. 4A and 4B) that cooperate with one or more handles 205. The enclosure 200 may be assembled from such components at a manufacturer and may not be disassembled by a consumer, for example. In some examples, different frames 220 and handles 205 may be mixed and matched to suit different applications (e.g., different features, colors, materials, sizes, etc.). The enclosure 200 may be designed to be fitted about the inner body 100 at a manufacturer and not to be removed by a consumer, for example to comply with safety regulations. In some examples, the enclosure 200 may be permanently attached to the inner body 100. For example, the enclosure 200 may be snap-fitted over the inner body 100, or the enclosure may be screwed or welded onto the inner body 100, as appropriate. Where appropriate, the enclosure 200 may include features to comply with safety regulations (e.g., warnings, manufacturer's information, color coding, etc.). For example, the inner body 100 may be manufactured without pigments (e.g., may be white) while the enclosure may be entirely or partially colored according to safety regulations (e.g., red to indicate gasoline is contained, yellow to indicate a diesel fluid is contained, or blue to indicate a kerosene fluid is contained). The assembly 1000 may include a cover 300 for at least one opening 115 of the inner body 100. In the example of FIGS. 1A and 1B, the cover 300 may include a dispensing portion, such as a spout 305, which may include a variety of interchangeable spouts or spout tips, for example as shown in FIG. 30 and as described elsewhere in the present disclosure, for dispensing fluid from the container. The assembly 1000 may also include a second cover 350 for at least one other opening 120 of the inner body (see FIG. 3). The opening 120 may be designed to fit a conventional fluid dispenser, such as a conventional commercial fuel dispenser (e.g., as provided at a gas station). The use of two covers 300, 350 may be suitable where the inner body 100 has separate openings 115, 120 for separately receiving and dispensing fluid, for example as shown in FIG. 3. Where the inner body 100 includes a single opening 115 for both receiving and dispensing fluid, for example as shown in FIG. 2, a second cover 350 may not be needed. FIGS. 13 and 14 illustrate another example cover 300b. The cover 300b may include a dispensing portion, such as a spout 305b similar to the spout 305, for dispensing fluid from the container. The cover 300b may also include a cap 310 which may be positionable over an opening 312 in the cover 300 to prevent fluid from escaping from the opening 312. By providing an opening 312 and a cap 310 on the cover 300b, a single cover 300b may be used where the inner body 100 includes a single opening 115 for both receiving and dispensing fluid, for example as shown in FIG. 2, while still providing the ability to both dispense fluid (e.g., through the spout 305b) and receive fluid (e.g., through the opening 312) without having to remove the spout or entire cover 300b which as discussed above may lead to contamination. The opening 312 may be designed to fit a conventional fluid dispenser, such as a conventional commercial fuel dispenser (e.g., as provided at a gas station). In some examples, the cover 300b may include an extended flat surface 313 surrounding the opening 312. The flat surface 313 may complement or mate with the vapor recovery inlet of a conventional commercial fuel dispenser, in order to help provide a more effective recovery of vapor during the refueling process. In some examples, the cover 300, 300b may be fixed over the opening 115 of the inner body 100, for example by a manufacturer, and may not be removable by a consumer. For example, the cover 300, 300b may be permanently fixed over the opening. In some examples, the cover 300, 300b may be removable (e.g., by a manufacturer) to be reused with multiple inner bodies 100, or to be replaced by other covers. In some examples, the cover 300, 300b may be removable by a consumer (e.g., the cover 300, 300b may be screwed onto the opening of the inner body 100). The portable fluid container assembly 1000 may be designed to container different amounts of fluids, as suitable. For example, the inner body 100 may be designed to contain 4 gallons (about 15.14 L) or 2 gallons (about 7.57 L), similar to conventional portable fuel containers. The components of the enclosure 200 may be suitably compatible and/or the size of the enclosure 200 may be suitably adjusted to fit different sizes of inner bodies 100. The portable fluid container assembly 1000 may be configured to allow two or more such assemblies 1000 to be fastened or joined together, which may facilitate transport of two or more assemblies 1000. FIGS. 5-9 illustrate an example of how such assemblies 1000 may be fastened together. As illustrated in greater detail in FIGS. 6 and 7, two or more assemblies 1000 may be brought together (e.g., side-by-side) by matching up respective mating member(s) 215. In this example, when brought together, the mating member(s) 215 include fingers that interleave with each other, preventing the assemblies 1000 from sliding sideways relative to each other. In some configurations, the mating member(s) 215 may also include features (e.g., a stop bar) that may prevent the assemblies 1000 from sliding vertically relative to each other. As illustrated in greater detail in FIGS. 8 and 9, a fastener 225 (e.g., a latch, a hook, a buckle, a snap, clamp or any other suitable fastener) may be provided on at least one of the assemblies 1000. The fastener 225 may enable the respective enclosures 200 of the assemblies 1000 to be held together, for example by fastening the respective handles 205 together. The fastener 225, together with the mating member(s) 215, may thus prevent relative motion between the assemblies 1000, and may enable the assemblies 1000 to be transported as one unit. Any other suitable means of interconnecting two or more assemblies to each other may be provided. In some examples, the design of the mating member(s) 215 may be such that most or all of the weight of the assemblies 1000 is supported by the mating member(s) 215 and the frames 220, such that the fastener 225 may not be required to withstand much force. Such a design may be useful to avoid unintentional unfastening of the fastener 225. In some example, more than one fastener 225 may be used to help improve joining of the assemblies 1000. FIG. 10 shows an example of how one or more assemblies 1000 may be transported. In the example shown, two assemblies 1000 are interconnected (e.g., in the manner described above) in a fashion suitable for transport. In this example, an assembly 1000 may be fitted with an extendable handle 205b (e.g., a telescoping handle) or a longer handle to facilitate towing by a user. In this example, wheels 230 may be fitted on an assembly 1000 (e.g., using a connector 235) to facilitate towing of the assembly 1000. For example, a frame 220 of the enclosure 200 may include one or more recesses or holes for fitting wheels 230 (e.g., using a connector 235 that may be locked in place by, for example pressing a button 235b). Such wheels 230 may be relatively easily added or removed by a consumer. Two or more assemblies 1000 may be fastened together, which may enable two or more assemblies 1000 to be relatively easily transported together in the manner illustrated. As shown more clearly in FIGS. 11 and 12, an assembly 1000 may also include a trigger 240 for controlling fluid flow from a dispenser, such as a spout 305, 305b. The trigger 240 may be located remotely from the spout 305, 305b, and may control a valve in the spout 305, 305b for controlling and regulating the flow from the spout 305, 305b via, for example, a cable 315 (see FIGS. 1A and 1B) that may run up the side of the assembly 1000 (e.g., via a cable guide 125 provided on the inner body 100 as shown in FIG. 12) from the trigger 240 to an openable and closable valve of the dispenser via a channel 320 in the cover 300, 300b, or any other suitable mechanism. In the example shown, the trigger 240 may be located near a base of the assembly 1000, for example adjacent the bottom end 1012 or at the base portion of the assembly 1000. Such a location may be easily accessible by a user's hand when a user upturns the assembly 1000 to pour fluid from the assembly 1000. The use of the remotely located trigger 240 may simplify the control of fluid flow (e.g., start of fluid flow, stop of fluid flow and/or flow rate) when dispensing fluid from the assembly 1000, and may prevent unintentional spilling of fluid when dispensing fluid from the assembly 1000. The trigger 240 may alternatively be located at any other suitable location on the container assembly (e.g., top, side or bottom). In some examples, there may be more than one trigger 240 provided, which may be useful in providing control of fluid flow from more than one hand position. For example, there may be one trigger 240 located near the base of the assembly 1000 (adjacent the bottom end 1012) and a second trigger 240 located near the top of the assembly 1000. FIGS. 62-65 illustrate another example spout 305c that may be provided on the cover 300, 300b. In some examples, the spout 305 may be similar to the spout 305b. The example shown illustrates the spout 305c provided on the cover 300b, although the spout 305c may be also used on the cover 300. The spout 305c may be controlled using the trigger 240 via the cable 315 (not shown), as described above. Additionally or alternatively, the spout 305c may include a safety trigger 325. The safety trigger 325 may help to ensure that fluid is delivered only when the spout 305c is sufficiently inserted into an inlet of a fluid destination. The safety trigger 325 may
