No. 62/251,156 entitled “Improved Matchbox-Type Packaging,” filed Nov. 5, 2015. The disclosures in these provisional patent applications are incorporated herein by reference in their entireties. 
    
    
     BACKGROUND 
     Technical Field 
     The present invention relates generally to a box-type package and, more particularly, to an improved matchbox-type package. The invention comprises a box having generally similar structure and function to that of a matchbox, although divergent in significant ways that allow for improved functionality and more efficient use. 
     Traditional matchbox structures have a rectangular parallelepiped sleeve, open at both ends, which totally transversely envelops a slidable tray. The tray has a similar parallelepiped configuration, open at its top, which is sized to be longitudinally slidable within the sleeve. Carrying a box of a traditional matchbox shape requires users who wear gloves (e.g., waiters, maître d&#39;s, busboys, downhill skiers, cross-country skiers, hikers, climbers, ice skaters, snowboarders, bicycle riders, motorcycle riders, or anyone residing in a seasonally-variant climate who might wear gloves to protect against the cold, etc.) to remove their gloves to fittingly insert a finger into one open end of the sleeve to push the tray out through the opposing open sleeve end. The invention disclosed herein allows the tray to be manipulated, and full access to the contents of the tray to be accessed, with one hand and without removing one&#39;s gloves. 
     The traditional matchbox continues to be efficient for certain products, such as matches, that are stored length-wise in the tray (i.e., longitudinally in the direction of tray sliding motion in the sleeve) because a user need only push open the matchbox to a small degree to remove a match from the tray. The present invention dramatically improves the matchbox structure for all products, particularly products that are oriented transversely of the structure (i.e., lengthwise in a width-wise direction within the tray). For products thusly oriented the traditional matchbox design and similar prior art packages are inefficient because it is very difficult to fully-access the products. That is, most men, and many women, are unable to push their fingers far enough into the sleeve to expose a sufficient length of the tray at its proximal end to permit full access to the contained products. As a result, to access all the contents of a box that are oriented transversely of the tray requires a user to manipulate the box with two hands. The present invention allows anyone to manipulate the box and render the full contents of the box totally accessible with one hand. 
     OBJECTS AND SUMMARY OF THE INVENTION 
     Therefore, in light of the above, and for other reasons that become apparent when the invention is fully described, it is one object of the present invention to provide an improvement in matchbox type packages that permits user&#39;s to readily access the package contents while wearing gloves and with the use of only one hand. 
     The present invention is an improvement over a conventional matchbox container of the type wherein an open tray is slidably contained in a sleeve. Whereas the conventional matchbox sleeve is open at both ends and closed at it top bottom and sides, the sleeve of the present invention has a proximal end wall with an aperture defined therein, and the bottom has a slot or channel defined lengthwise therein in direct and longitudinally continuous communication with the proximal end wall aperture. The longitudinally continuous aperture and channel permit a user to pass a finger into the aperture and then uninterruptedly lengthwise through the channel to cause the tray to be pushed and extended distally to thereby permit the tray contents to be exposed through the open distal end of the sleeve. 
     The container of the present invention is of the matchbox type comprising a tray having proximal and distal ends, a sleeve for receiving the tray in longitudinally slidable relation distally within the sleeve, wherein said sleeve comprises: an open distal end configured to permit the distal end of the tray to be extended distally therefrom; a proximal end wall having a bottom edge and an aperture defined through the proximal end wall at the bottom edge; and a bottom wall having a longitudinally extending slot defined therethrough and extending distally from and in direct longitudinally continuous (i.e., uninterrupted) communication with the aperture; wherein the aperture and slot are configured to permit a user to expose contents of said tray by inserting a finger through the aperture and then uninterruptedly into an through the slot to push against the proximal end of the tray. 
     The above and still further features and advantages of the present invention will become apparent upon consideration of the following definitions, descriptions and descriptive figures of specific embodiments thereof wherein like reference numerals in the various figures are utilized to designate like components. While these descriptions go into specific details of the invention, it should be understood that variations may and do exist and would be apparent to those skilled in the art based on the descriptions herein.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     It is intended that the description below not be limited to terms of orientation that are used for convenience and ease of understanding. Specifically, it is to be understood that terms such as “top”, “bottom”, “front”, “rear”, “side”, “length”, “width”, “transverse”, “upper”, “lower”, “interior”, “exterior”, “inner”, “outer” and the like as may be used herein, merely describe points of reference and do not limit the present invention to any particular orientation or configuration. In addition, the specific dimensions set forth below are by way of example for particular embodiments to assist in an understanding of the illustrated structure; these dimensions are not to be construed as limiting the scope of the invention. 
     Referring specifically to  FIGS. 1-4 and 6 , the container  10  of the present comprises a tray  11  arranged to be sealed when fully-enclosed in a sleeve  12 . In this preferred embodiment of the invention the sleeve  12  is a rectangular parallelepiped having an open distal end  13  and an opposite proximal end wall  14 . Proximal end wall  14  is closed except for an arched aperture  15  defined therethrough having spaced ends terminating at the bottom wall  16  of the sleeve and extending approximately halfway up the otherwise closed end wall  14 . In this embodiment of the invention aperture  15  takes the form of a segment of a circle that is semi-circular or slightly smaller that a semi-circle. The sidewalls and top wall of the sleeve are preferably entirely closed. The bottom wall  16  of the sleeve is closed except for a channel  17  cut therethrough and extending distally lengthwise from the proximal end wall  14  in communication with aperture  15 . In other words, channel  17  has an open proximal end coterminous with the bottom open edge of aperture  15 . The distal end  18  of channel  17  is closed and, in this embodiment, is arcuate with a shape matching that of aperture  15 . It should be noted that the distal end  18  of the channel need not be arcuate and can take any configuration that is consistent with the functions and operation described herein. 
     Tray  11  is in the form of a rectangular parallelepiped open at its top with entirely closed walls at its front, back, sides and bottom. The tray is sized to closely fit inside sleeve  12  in longitudinally slidable relation in the same manner as in a conventional matchbox. Tray  11  serves to receive and contain package contents (e.g., matches, pills, candies, tea leaf portions, pouches, tobacco, etc.) which are typically inserted into and removed from the open tray top. 
     Aperture  15  allows a finger to be introduced therethrough and then extended in the sleeve along channel  17 . Channel  17  extends from aperture  15  for a distance typically between fifty and ninety percent of the length of the sleeve. As illustrated in  FIG. 6 , this allows a user&#39;s single finger, typically an index finger, to push the tray  11  from the proximal end  14  of the sleeve along the channel  17  as necessary to expose the desired amount of the contents inside the open top tray. Such manipulation can occur with the user&#39;s index finger while the sleeve is grasped between the user&#39;s thumb and other digits of the same hand. For products that are stored width-wise within the tray, these products can all be accessed as the tray is fully-extended. It is very difficult for a large segment of the population, if not almost everyone, to extend a tray fully by pushing a finger through an open ended sleeve of a traditional matchbox which can have an open proximal sleeve end as narrow as five millimeters; and which action, even were it to be successful, would necessarily require the use of the user&#39;s other hand to pull the tray from the distal end. 
     Typically the container components may be made of plastic, metal, cardboard or any suitable material consistent with the properties and functions described herein. In the illustrated embodiment the width of channel  17  transversely of the sleeve is between 36%-66% of the sleeve width, although in some embodiments the channel can be between 10%-90% of the width of the sleeve. The length of the channel is optimally 50%-85% of the length of the sleeve but the channel can be between 5%-95% of the length of the sleeve for some embodiments depending, for example, on the materials used and the structural rigidity of the sleeve. Importantly, the channel width (and the aperture diameter) must be sufficient to receive the tip of an index finger of a person (possibly a gloved index finger), and for this purpose should be at least 12 mm, and preferably about 18 mm. 
     With regard to typical overall dimensions, by way of example only, the embodiment of  FIG. 1  may have the following approximate dimensions:

     Blanks for a cardboard embodiment of the embodiment described above are illustrated in  FIG. 7  (for the sleeve) and  FIG. 8  (for the tray), it being understood that the tray and sleeve components are formed by folding the blanks along indicated dashed lines and securing the sections as necessary with adhesive or other means. Referring to the sleeve blank in  FIG. 7 , the sidewalls are folded toward one another along fold lines  22 ,  29 , respectively, out from the plane of the drawing until perpendicular to the top wall. The sleeve bottom wall  16  is then folded along fold line  23  out of the plane of the drawing until perpendicular to the abutting sidewall. The tab  25  extending from the side of bottom wall  16  is then folded along fold line  24  until its outer surface (facing into the drawing plane in  FIG. 7 ) abuts the interior surface of the opposite sidewall  21 . Glue or other adhesive material is used to secure tab  25  to that abutting interior sidewall surface. Tabs  26 ,  27  at the proximal ends of the sidewalls are then folded so as to be perpendicular to their respective sidewalls, and tab  28  at the proximal end of the sleeve top wall is folded over folded tabs  26 ,  27  until perpendicular to the top wall. A slot  30  is defined transversely across tab  28  adjacent the juncture between that tab and the sleeve top wall and is configured to receive tab  31  extending from the top edge of proximal end wall  14 . End wall  14  is folded along fold line  33  at the juncture between end wall  14  and bottom wall  16  until those walls are perpendicular, and tab  31  is folded and inserted into slot  30 . 
     It should be noted that slot  17  and aperture  15  are formed as a single cut out in the sleeve blank. This assures the required longitudinal continuity between the aperture and slot in the assembled unit  10  that permits a user&#39;s finger to enter the slot from the aperture and push the tray to the desired extension from the open distal end of the sleeve. 
     As described, the sleeve blank illustrated in  FIG. 7  is formed with fold lines between successive side, top and bottom sections along the long dimension of the edges of the sections. This configuration allows for gluing at a single location and permits the sleeve to be collapsed and shipped flat and then be easily manipulated into a three dimensional parallelepiped sleeve shape when received and assembled. The locking tab  31  at the top edge of the proximal closed end section retains that shape when inserted into the approximately 20 mm slot  30  formed in the rear fold line between the top of the sleeve and the flap  28  extending therefrom. Tab  31  may be slightly wider than the length of slot  30  and provided with notches at its opposite ends to facilitate locking of the tab in slot  30  in a conventional manner; this prevents inadvertent removal of the tab and unfolding of the sleeve proximal end wall  14 . The projecting corners of the proximal end wall  14  are rounded so that they will not readily deform (i.e., bow out or bend) and will fit flat against the end of the tray in the assembled unit. Although this particular blank configuration has advantages, it will be appreciated that other blank configurations can be used to form a sleeve that functions as required for the present invention. 
     The tray blank in  FIG. 8  has a rectangular base section  41  bounded on all four sides by respective fold lines comprising respective junctions with the side and end walls of the tray  11 . Corner wing-like sections  42 ,  43 ,  44  and  45  extend between the side walls and adjacent end walls and include fold lines that permit the corner sections to be folded inwardly along those fold lines as the side and end walls are folded upwardly to form the tray parallelepiped structure. A short first extension section  46  extends from a fold line  47  at the top edge of one end wall (to the left in  FIG. 8 ) and includes a transverse intermediate fold line  48  proximate its longitudinal center that divides the section into inner portion  49  and outer portion  50 . Inner portion  49  has substantially the same configuration as its adjacent end wall  41   a . Section  46  can be folded over its adjacent end wall along fold  47  and the folded corner sections  42  and  45 , and then along intermediate fold line  48  so that the remote end  50  of section  46  resides in adjacent abutting relation to base section  41  to form an interior partial layer of the bottom wall of the tray. 
     A long second extension section  51  extends from a fold line  52  at the top edge of the opposite end wall and includes a transverse intermediate fold line  53  that divides it into a relatively short inner portion  54  and a substantially longer outer portion  55 . Inner portion  54  has substantially the same configuration as its adjacent end wall  57  that shares fold line  52 . Section  51  can be folded over its adjacent end wall and the folded corner section  43  and  44 , along fold line  52 , and then along intermediate fold line  53  so that the remote end portion  55  resides in adjacent abutting relation to base section  41 , overlying the outer portion  50  of the extension at the opposite end of the tray, to form an interior part of the bottom wall of the tray. The length of portion  55  in the illustrated embodiment is substantially the same as the length of base  41  so that it almost entirely covers the base  41  and portion  50 . The plural layers  41 ,  50  and  55  thusly forming the bottom wall of the tray add to the strength and structural integrity of the assembled tray. 
     Importantly, the aperture  15 , although preferably arcuate as shown in  FIGS. 3, 4 and 6 , can be substantially any configuration that is consistent with the intended function and operation described herein. For example, the aperture can be rectangular, as shown in  FIG. 6  as aperture  5 , triangular, polygonal, or any regular or irregular shape. The important point is that the aperture is directly communicative with slot  17  (shown as slot  7  in  FIG. 6 ) so that a user&#39;s finger can enter the aperture and be moved substantially unimpeded through the slot. Slot  7  is also shown with a transversely straight distal end, which is an alternative to the arcuate distal end of slot  17  in  FIGS. 3 and 4 . 
     The key elements of the invention work in concert in that the combination of the aperture  15  and the channel  17  allows a single finger of a user to access and fully-extend the tray within the sleeve. This is in direct contrast to prior art modifications of traditional matchbox structures in different ways and for different functions. In more than a hundred years of design and re-design of the traditional matchbox shape, no prior configuration has introduced an apertured proximal end wall as a way to more easily access the back of the tray to push it forward or, separately and in conjunction, introduced the channel as a means for easily and efficiently permitting the tray to be pushed forward for accessing the full contents of the tray whether they are stored length-wise or width-wise. For people who engage in activities in the outdoors in cold climates, the present invention will improve their comfort level and safety when manipulating the tray in the sleeve. 
     The present invention is also an improvement in environmental efficiency in that it allows greater ease of access to the full contents of the box, improves access and performance for users, and uses less raw material in the manufacture of the product. 
     Although the sleeve and tray in the disclosed embodiments are concentric rectangular parallelepipeds, it is to be understood that they can have other configurations such as, for example, circular, elliptical or polygonal cylinders or tubes, as long as the sleeve is open at its distal end and there is an aperture in the proximal end wall in spatial longitudinal communication with a channel defined along part of the length of the sleeve bottom wall. In any of these embodiments, the user can slide the tray so that it can be partially (or, if desired, fully) extended from the open end of the sleeve by merely pushing with one finger though the rear sleeve wall aperture and along channel in the bottom wall. 
     Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation. 
     Having described preferred embodiments of new and improved matchbox-type packaging, it is believed that other modifications, variations and changes will be suggested to those skilled in the art in view of the teachings set forth herein. It is therefore to be understood that all such variations, modifications and changes are believed to fall within the scope of the present invention as defined by the appended claims.
A matchbox-type container wherein the sleeve has a proximal end wall with an aperture defined therein, and the bottom has a slot or channel defined lengthwise therein in direct and longitudinally continuous communication with the proximal end wall aperture. The longitudinally continuous aperture and channel permit a user to pass a finger into the aperture and unimpededly lengthwise through the channel to cause the tray to be pushed and extended distally, thereby permitting the tray contents to be exposed through the open distal end of the sleeve.
