Abstract

This disclosure relates to transfer plate lubricant compositions and methods of transporting open containers across stationary transfer plates.

First claim

We claim:

1. A method of lubricating a stationary transfer plate comprising: diluting a concentrated lubricant composition to form a dilute lubricant composition; applying the dilute lubricant composition to a stationary transfer plate to provide coverage of about 0.05 to about 0.2 mL/cm 2 of dilute lubricant composition, the concentrated lubricant composition comprising:
an oil;
an emulsifier;
a water-miscible lubricant;
an antimicrobial agent; and
water; and

transporting a filled, unclosed container across the stationary transfer plate with a forward translational velocity of greater than 40 feet per minute.

2. The method of claim 1 , wherein the dilute lubricant composition is applied from at least one nozzle or bubbler under the transfer plate at a rate of about 2 to 10 gallons of dilute lubricant composition per hour per nozzle or bubbler.

3. The method of claim 1 , wherein the oil is selected from the group consisting of silicone oil, mineral oil, a fatty acid having more than 8 carbon atoms, trimethylol propane, trioleate, a triglyceride, and derivatives thereof.

4. The method of claim 1 , wherein the oil is a silicone oil.

5. The method of claim 4 , wherein the silicone oil comprises polydimethylsiloxane.

6. The method of claim 1 , wherein the emulsifier is a nonionic surfactant.

7. The method of claim 1 , wherein the concentrated lubricant composition comprises from about 0.5 wt. % to about 5 wt. % silicone oil.

8. The method of claim 1 , wherein the dilute lubricant composition comprises from about 0.0005 wt. % to about 0.001 wt. % silicone oil.

9. The method of claim 1 , wherein the antimicrobial agent is selected from the group consisting of a quaternary ammonium compound, an isothiazolone compound, a peroxycarboxylic acid, hydrogen peroxide, an amine, a halogen, and combinations thereof.

10. The method of claim 1 , wherein the dilute lubricant composition is applied from up to 6 nozzles or bubblers.

11. The method of claim 1 , wherein the dilute lubricant composition is applied at a rate of about 6 to about 8 gallons per hour per nozzle or bubbler.

12. The method of claim 1 , wherein the dilute lubricant composition is applied continuously.

13. The method of claim 1 , wherein the dilute lubricant composition is applied discontinuously.

14. The method of claim 1 , further comprising transporting containers over the stationary transfer plate in a single file at a rate of up to 2200 cans per minute.

15. The method of claim 1 , wherein the oil is applied to the transfer plate in an amount between about 1 and about 100 mg/hour.

16. The method of claim 1 , wherein the water-miscible lubricant is selected from the group consisting of an amine, a phosphate ester, and derivatives thereof.
