Conveyor lubricant, passivation of a thermoplastic container to stress cracking and thermoplastic stress crack inhibitor
US 6673753 B2
1. A container, comprising a thermoplastic material subject to stress cracking, the container comprising a shaped article with a portion of the article under stress, the container comprising a thermoplastic resin and about 1 to 1000 milligrams, per gram of the thermoplastic, of a liquid hydrocarbon oil stress cracking inhibitor.
3. The container of claim 1 wherein the liquid hydrocarbon oil is a liquid with a viscosity of less than about 500 cSt at 40° C.
(a) forming a shaped article from a thermoplastic in a thermal shaping process resulting in a portion of the article with stress; and
(b) forming a coating on the surface of the article, the coating comprises a liquid hydrocarbon oil present in an amount of about 0.1 to 100 milligrams per square meter, wherein the liquid hydrocarbon oil comprises an aliphatic oil with a viscosity of less than 50 cSt at 40° C.
15. A method of lubricating a conveyor used in transporting thermoplastic containers, the method comprises conveying a thermoplastic container on a conveyor belt and applying to the conveyor belt a liquid hydrocarbon oil lubricant composition.
31. The method of claim 29 wherein the hydrocarbon oil comprises a hydrocarbon oil having a viscosity of less than about 50 cSt at 40° C.
37. The method of claim 36 wherein the liquid lubricant comprises an emulsion of an organic phase and an aqueous phase.
41. The method of claim 36 wherein the liquid lubricant is applied to the surface of the conveyor in an amount of about 2×10−4 to 0.05 grams of lubricant per each square inch of surface.
We have found that the problems inherent in conventional aqueous lubrication of conveyor systems used in food packaging and beverage bottling can be substantially improved using a continuous thin film lubricant layer formed on a conveyor surface. The lubricant layer is maintained at a thickness of less than about 3 millimeters, preferably about 0.0001 to 2 mm, with an add on of lubricant on the surface of less than about 0.05 gms-in−2, preferably about 5×104 to 0.02 gms-in−2, most preferably about 2×10−4 to 0.01 gms-in−2. Such a thin lubricating film of the lubricant on the conveyor provides adequate lubrication to the conveyor system but ensures that the lubricant cannot foam, does not flow from the conveyor surface and contacts the absolute minimum surface area of the food container such as the beverage bottle as possible. Such a thin film lubricant maintains significant lubrication while avoiding waste of the lubricant composition and avoiding stress cracking promotion. We have found that one mode of formation of the liquid lubricant compositions of the invention are in the form of an aqueous oil emulsion wherein the aqueous phase comprises about 10 to 50 wt % of the lubricant. The form of the emulsion can be either water in oil or oil in water emulsion. One preferred format of the emulsion is a phase unstable emulsion such that the emulsion separates forming an oil layer on top of a water layer which is then, in turn, contact with the conveyor surface. The methods of the invention can be used to convey virtually any food container on a conveyor line, but is particularly adapted to transporting both steel and aluminum cans and thermoplastic beverage containers such as polyethylene terephthalate beverage containers. Common PET beverage containers are formed with a pentaloid base having a five lobed structure in the base to provide stability to the bottle when it is placed on a surface. The contact with the lubricant on the pentaloid base must be minimized. We have found that using a thin film of emulsion lubricant, that less than about 10 to 300 mm2, preferably 20 to 200 mm2 of the surface of the bottle is contacted with lubricant. Certainly, the height of the lubricant in contact with the bottle is less than 3 millimeters. The motion of the conveyor, the tendency of the bottles to rock or move while being conveyed and the other aspects of relative movement at the bottle conveyor interface affect the height of the lubricant on the bottle. The methods of this invention are primarily directed to conveyor operations and do not involve any change in shape of the container arising from forming operations. The desirable coefficient of friction of the conveyor lubricant is about 0.1 to about 0.14.
A highly refined fatty oil can also be used in the applications of the invention. Such oils can include both animal and vegetable derived oils. Such oils are typically fatty acid triglycerides formed from highly unsaturated fatty acids or relatively low molecular weight triglycerides formed from fatty acids having 4 to 12 carbon atoms. Preferred hydrocarbon oils of the invention comprise refined vegetable oils combined with antioxidant, antimicrobial and other stabilizing additive materials. One very important property of liquid hydrocarbon oils is viscosity. Viscosity of an oil is related to the stiffness or internal friction of the materials as each lubricant oil molecule moves past another. The preferred parameter for measuring viscosity is kinematics viscosity in mm2-sec−1 (also known as centistokes, cSt). The preferred viscosity of the hydrocarbon oils of this application is typically less than 50 mm2-sec−1, preferably less than 30 mm2-sec−1, most preferably less than 20 mm2-sec−1 at 40° C. an less than 15 mm2-sec−1, preferably less than 10 mm2-sec−1, most preferably less than 5 mm2-sec−1 at 100° C. The viscosity of the materials above 100° C. is substantially irrelevant with respect to treating or lubricating thermoplastic materials. Most thermoplastics are used at temperatures that range from about 20° C. to about 40° C.
These polymer materials can be used for making virtually any container that can be thermoformed, blow molded or shaped in conventional thermoplastic shaping operations. Included in the description of containers of the invention are containers for carbonated beverages such as colas, fruit flavored drinks, root beers, ginger ales, carbonated water, etc. Also included are containers for malt beverages such as beers, ales, porters, stouts, etc. Additionally, containers for dairy products such as whole, 2% or skim milk are included along with containers for juices, Koolaid® (and other reconstituted drinks), tea, Gatoraid® or other sport drinks, neutraceutical drinks and still (non-carbonated) water. Further, food containers for flowable but viscous or non-Newtonian foods such as catsup, mustard, mayonnaise, applesauce, yogurt, syrups, honey, etc. are within the scope of the invention. The containers of the invention can be virtually any size including (e.g.) five gallon water bottles, one gallon milk chugs or containers, two liter carbonated beverage containers, twenty ounce water bottles, pint or one half pint yogurt containers and others. Such beverage containers can be of various designs. Designs can be entirely utilitarian with a shape useful simply for filling transportation, sales and delivery. Alternatively, the beverage containers can be shaped arbitrarily with designs adapted for marketing of the beverage including the classic “coke” shape, any other decorative, trademarked, distinctive, or other design can be incorporated into the bottle exterior.
A liquid hydrocarbon oil material is made by combining a paraffinic solvent, petroleum white oil, a stabilized-modified vegetable oil and a dispersed Teflon® particulate.

The charged bottle was placed in the plastic bag that contained 100 g of the diluted Lubodrive RX. Also the experimental was carried out in the environmental oven at 37.8° C. and 90% humidity for 13 days instead of 15 days.
The bacteria, staphylococcus aureus ATCC6538 and enterobacter aerogenes ATCC 13048, were transferred and maintained on nutrient agar slants. Twenty-four hours prior to testing, 10 mls of nutrient broth was inoculated with a loopful of each organism, one tube each organism. The inoculated nutrient broth cultures were incubated at 37° C. Shortly before testing, equal volumes of both incubated cultures were mixed and used as the test inoculum.

Coefficient of friction (COF) measured on a short track conveyor system: The determination of lubricity of the lubricant was measured on a short track conveyor system. The conveyor was equipped with two belts from Rexnord. The belt was Rexnord LF (polyacetal) thermoplastic belt of 3.25″ width and 20 ft long. The lubricant was applied to the conveyor surface evenly with a bottle wash brush. The conveyor system was run at a speed of 100 ft/min. Six 2L bottles filled with beverage were stacked in a rack on the track with a total weight of 16.15 kg. The rack was connected to a strain gauge by a wire. As the belts moved, force was exerted on the strain gauge by the pulling action of the rack on the wire. A computer recorded the pull strength. The coefficient of friction (COF) was calculated on the basis of the measured force and the mass of the bottles and it was averaged from the beginning to the end of the run. The results of the testing of example 25 are shown in a graphical form in FIG. 5.
