Abstract
The present invention relates to conveyor lubricant compositions including an emulsion of a lipophilic compound and also including an emulsifier and/or an anionic surfactant. The present invention also relates to methods employing such lubricant compositions. In an embodiment, the method includes applying the present lubricant composition to a conveyor with a non-energized nozzle.
Claims35
A method for lubricating the passage of a container along a conveyor, comprising:
- applying a lubricant composition to at least a portion of a container-contacting surface of the conveyor or to at least a portion of a conveyor-contacting surface of the container;
- the lubricant composition comprising alcohol ethoxylate propoxylate, the lubricant composition having an alkalinity of 100 ppm of CaCO3 or less, and the lubricant composition does not comprise amine or amine derivative lubricants,
- wherein applying comprises applying the lubricant composition for a first length of time and not applying the lubricant composition for a second length of time, and wherein the ratio of the first length of time to the second length of time is about 1 to greater than or equal to about 10, and
- wherein the lubricant composition is PET bottle compatible.
A method for lubricating the passage of a container along a conveyor comprising:
- applying a lubricant composition to at least a portion of a container-contacting surface of the conveyor or to at least a portion of a conveyor-contacting surface of the container,
- the lubricant composition comprising alcohol ethoxylate propoxylate, the lubricant composition having an alkalinity of 100 ppm of CaCO3 or less, and the lubricant composition does not comprise amine or amine derivative lubricants,
- wherein the lubricant composition is free of silicone,
- wherein applying comprises applying the lubricant composition for a first length of time and not applying the lubricant composition for a second length of time, and wherein the ratio of the first length of time to the second length of time is about 1 to greater than or equal to about 10, and
- wherein the lubricant composition is PET bottle compatible.
A method for lubricating the passage of a container along a conveyor comprising:
- applying a lubricant composition to at least a portion of a container-contacting surface of the conveyor or to at least a portion of a conveyor-contacting surface of the container,
- the lubricant composition comprising alcohol ethoxylate propoxylate, the lubricant composition having an alkalinity of 100 ppm of CaCO3 or less, and the lubricant composition does not comprise amine or amine derivative lubricants,
- wherein the lubricant composition creates a coefficient of friction on the conveyor of less than about 0.15,
- wherein applying comprises applying the lubricant composition for a first length of time and not applying the lubricant composition for a second length of time, and wherein the ratio of the first length of time to the second length of time is about 1 to greater than or equal to about 10, and
- wherein the lubricant composition is PET bottle compatible.
