International Classification:

B65G 4502

US Classification:

198500, 508113

Abstract:

A process for lubricating a container, such as a beverage container, or a conveyor for containers, by applying to the container or conveyor, a thin continuous, substantially non-dripping layer of a liquid lubricant. The process provides many advantages compared to the use of a conventional dilute aqueous lubricant.

US Classification:

427512, 427487, 427521, 4273722, 4273855, 508579

Abstract:

The passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricating coating that is thermally cured at less than 200Â C. or radiation-cured. The mixture can be applied in relatively low amounts and with relatively low or no water content, to provide thin, substantially non-dripping, renewable lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide dry lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

Abstract:

The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts and with relatively low or no water content, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

Abstract:

We have found that a clear, stable microemulsion can be used during container transport operations during which the container is contacted with a transparent dispersion of hydrophilic and oleophilic materials. A process for lubricating a container, such as a beverage container, or a conveyor for containers, by applying to the container or conveyor, a thin continuous, substantially non-dripping layer of a transparent dispersed liquid lubricant. The process provides many advantages compared to the use of a conventional lubricant diluted with water.

International Classification:

US Classification:

Abstract:

The interface between a moving conveyor belt and a work piece can be lubricated using an air driven stream of finely divided droplets of a lubricant composition. Droplets of a preferred size are directed by the air stream onto the conveyor with little waste of lubricant off the conveyor. The lubricant provides a very low coefficient of friction and little or no stress cracking in the containers. Using a low pressure and low flow rate air stream in conjunction with a low flow rate liquid lubricant attains the useful particle size in the lubricant add on spray. The liquid lubricant is sheared by the effect of the air flow creating the desirable droplet size and pattern of lubricant on the conveyor. A food container conveyor device having improved lubricant properties can be lubricated using a lubricant composition that can become ingested by a user from a food or a container for the food, can come into incidental contact or direct content with a food composition, can be incorporated at measurable concentrations into the food, or can be used generally on food conveyor surfaces wherein the food is exposed to the lubricant.

Assignee:

Ecolab Inc. - St. Paul MN

International Classification:

R65G 4502

US Classification:

198500

Abstract:

The passage of a container along a conveyor is lubricated by applying to at least a portion of the container-contacting surface of the conveyor or to at least a portion of the conveyor-contacting surface of the container a coating comprising a hydrophilic material wherein the lubricating properties of the coating are enhanced by contact with a polar liquid; polymerizing or otherwise solidifying the coating; and contacting the coating with such polar liquid. If desired, the coating can be applied or polymerized on the conveyor or container while the conveyor line is in motion.
