This application claims priority under 35 U.S.C. §119(e) to U.S. provisional application Ser. No. 60/230,662, filed on Sep. 7, 2000, incorporated by reference herein. This application is also a continuation in part of U.S. Ser. No. 09/738,387, filed on Dec. 15, 2000 abandoned.
This invention related lubricants for food packaging lubricated packaging business methods and to lubricated food containers and lubricated and conveyor apparatus that can move the container or container plus food composition during production. Such conveyors typically move the containers to stations that incorporate the food composition into the container and then further direct the container or food and container to stations that can clean the container, apply labels, seal or package the container for further shipment. The invention related to lubricating conveyors that support and transport work piece. The invention related to methods of use, for example, to treat or lubricate a container(s) and conveyor surfaces or system for containers. Containers can be made of glass, metal or plastic. The container is, for example, a food or beverage container. More particularly, the invention related to a conveyor system for transporting both empty and filled polyester beverage containers of various sizes.
These commercial aqueous conveyor lubricants, conventionally based on fatty acids, anionic surfactants, ethoxylated amines or fatty amines, are not currently qualified for contact or indirect contact with food. Any contact between food and lubricant can render the food unfit for human consumption under current FDA regulations including for example 21 CFR §§1.172, 1.178 and 1.182. These regulations also define “food grade” additive materials. Further, such lubricants typically contain ingredients that can promote microbes or can react with spilled carbonated beverages or other food or liquid components to form unwanted solid deposits.
When first used with beverage containers, such conveyor systems were lubricated using dilute aqueous lubricant materials, typically, substantially soluble sodium salt of the fatty acid or sodium salt of linear alkane sulfonate which acted to both lubricate and at least to some degree, clean the conveyor surfaces. Representative examples of such lubricants are found in Stanton et al., U.S. Pat. No. 4,274,973 and Stanton, U.S. Pat. No. 4,604,220. Many current conveyor lubricant systems are classified H-2 according to regulations in 21 CFR §§1.172, 1.178 and 1.182. Such systems are not approved for incidental, indirect or direct contact with beverage compositions. Any contact between H-2 lubricant materials and foods that incorporates any important amount of lubricant into beverage renders the beverage unsuitable for human consumption. Significant problems have arisen when H-2 lubricants have come into contact with food materials. When the food materials, often beverages or other comestibles have been contaminated with such H-2 lubricants, recalls of these materials have occurred resulting in substantial loss to the manufacturer. Because of the safety concerns and the potential of financial lawsuit to manufacturers, the use of H-2 lubricants can often pose substantial operating costs and administrative costs including regulatory review personnel insurance and other costs not directly related to the costs of lubricating conveyor lines and the costs of maintaining food purity. Accordingly, a substantial need exists in the art to obtain lubricants that can be used in a way on lubricating lines and with respect to containers and containers containing food such that the food can come into incidental, indirect or direct contact with lubricating compositions without rendering the food unfit for human consumption.
We have also found that the lubricating systems are well adapted to food grade or H-1 lubricants. Any spray that is conveyed onto or into the food in a container must not render the food unfit for human consumption. The use of an H-1 grade lubricant in such a conveyor system can alleviate many concerns with respect to contacting the food material with the lubricant material. Should some amount of the lubricant come into direct, incidental or indirect contact with the food, the presence of the H-1 lubricant in the food does not render the food unsuitable for human consumption. “Food” as used in this application means any substance ingested by humans including liquid, solid, semisolid, composite comestible materials in the form of water, carbonated beverage, a food, juice, sports beverage, snack, edible container or carrier. Such a process an result in substantial savings in the operation of the food manufacturing and packaging operation and can also result in substantial savings of money in general administrative and operating expenses by reducing costs of recall of contaminated materials (in contact with H-2 lubricants) and in reduced administrative costs such as reduced insurance costs. U.S.D.A. H-1 lubricants are regulated in 21 C.F.R. §178 (at 178.3570), 21 C.F.R. §1.72 and 21 C.F.R. §1.82. The materials are formulated to contain ingredients that both lubricate and pass the stringent guidelines of the Federal regulations. For the purposes of this application the terms “Direct, Incidental or Indirect” contact between lubricant and food means that the food acquires an amount of lubricant. This amount if in the form of an H-2 composition would render the food unfit for human consumption. For the purpose of this specification and claims, the term “coating” is intended to mean a continuous or discontinuous thin liquid layer of the lubricant dispersions of the invention on a moving conveyor surface. Applying the liquid to the surface such that the surface of the conveyor is substantially completed covered with the lubricant can form such a coating. Alternatively, the term “coating” can also connote the continuous or the intermittent timed application of the lubricant such that the lubricant can be applied intermittently to a surface of a moving conveyor. The intermittent application of the lubricant can form a continuous layer and still provide an adequate lubricating layer on the surface. The lubricant coatings of the invention can develop areas of the conveyor that do not have any substantial quantity of liquid lubricant as the lubricant interacts with the conveyor surface, the containers and the changing conditions as the conveyor moves through the structure. For the lubricant to work successfully, there must be an amount of lubricant at the container conveyor interface to obtain reduced coefficient of friction. In other words, a successful lubricant coating is present when the lubricant is present at the interface to successfully reduce friction during conveying of a container from place to place on a conveyor.
Specific examples of useful lubricants include oleic acid, corn oil, mineral oils available from Vulcan Oil and Chemical Products sold under the “Bacchus” trademark; fluorinated oils and fluorinated greases, available under the trademark “Krytox” from is DuPont Chemicals. Also useful are siloxane fluids available from General Electric silicones, such as SF96-5 and SF 1147 and synthetic oils and their mixture with PTFE available under the trademark “Super Lube” from Synco Chemical. Also, high performance PTFE lubricant products from Shamrock, such as nanoFLON M020™, FluoroSLIPT™ 225 and Neptune™ 5031 and polyalkylene glycols from Union Carbide such as UCON™ LB625, and Carbowax™ materials are useful.
A variety of water-miscible silicone materials can be employed in the lubricant compositions, including silicone emulsions (such as emulsions formed from methyl(dimethyl), higher alkyl and aryl silicones; functionalized silicones such as chlorosilanes; amino-, methoxy-, epoxy- and vinyl-substituted siloxanes; and silanols). Suitable silicone emulsions include E2175 high viscosity polydimethylsiloxane (a 60% siloxane emulsion commercially available from Lambent Technologies, Inc.), E2140 FG food grade intermediate viscosity polydimethylsiloxane (a 35% siloxane emulsion commercially available from Lambent Technologies, Inc.), HV490 high molecular weight hydroxy-terminated dimethyl silicone (an anionic 30-60% siloxane emulsion commercially available from Dow Coming Corporation), SM2135 polydimethylsiloxane (a nonionic 50% siloxane emulsion commercially available from GE Silicones) and SM2167 polydimethylsiloxane (a cationic 50% siloxane emulsion commercially available from GE Silicones. Other water-miscible silicone materials include finely divided silicone powders such as the TOSPEARL™ series (commercially available from Toshiba Silicone Co. Ltd.); and silicone surfactants such as SWP30 anionic silicone surfactant, WAXWS-P nonionic silicone surfactant, QUATQ-400M cationic silicone surfactant and 703 specialty silicone surfactant (all commercially available from Lambent Technologies, Inc.). Preferred silicone emulsions typically contain from about 30 wt % % to about 70 wt % water. Non-water-miscible silicone materials (e.g., non-water soluble silicone fluids and non-water-dispersible silicone powders) can also be employed in the lubricant if combined with a suitable emulsifier (e.g., nonionic, anionic or cationic emulsifiers). For applications involving plastic containers (e.g., PET beverage bottles), care should be taken to avoid the use of emulsifiers or other surfactants that promote environmental stress cracking in plastic containers when evaluated using the PET Stress Crack Test set out below. Polydimethylsiloxane emulsions are preferred silicone materials. Preferably the lubricant composition is substantially free of surfactants aside from those that may be required to emulsify the silicone compound sufficiently to form the silicone emulsion.
The aqueous or oleophilic diluents contemplated above can be combined with a variety of lubricant materials. Lubricant materials can be used as is or in combination with a variety of other functional additives for their known uses. The following nonexclusive list provides direction for selecting H-1 ingredients. This list of ingredients should be read in concert with 21 C.F.R. §§1.172, 1.178 and 1.182 which are expressly incorporated by reference herein for a description of foodgrade or H-1 qualified materials and their uses.

The determination of lubricity (Coefficient of friction (COF) 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 dry 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.
