Embodiment 1

[0107] Example 1 tested the ability of the compositions of the present invention to provide lubrication on a glass bottle conveyor line. For this example, compared to the known commercially available conveyor belt lubricant LUBODRIVE from Ecolab Inc. (St. Paul, MN) TM (An Amine Conveyor Belt Lubricant) Test Formulation 1. The formulation of Formulation 1 is provided in Table 2. The formulations are provided in wt%.

[0108] Table 2 Conveyor Belt Lubricant Formulations

[0109]

[0110] Formulation 1 and LUBODRIVE on stainless steel conveyors for 300ml and 1800ml glass bottles at 550 bottles / min and 300 bottles / min respectively TM Lubricants are tested. The coefficient of friction is measured at various locations along the conveyor line. During a production run, test containers representing the packages used on the production line are connected to the strain gauges through a synthetic line and placed on the moving production line conveyor. The test container is dragged...

Embodiment 2

[0115] Example 2 compares the foam generation of the compositions of the present invention with other known lubricants. For this example, the formulations in Table 4 were mixed with LUBODRIVE GLF commercially available from Ecolab Inc. (St. Paul, MN). TM and LUBOKLAR XT TM (two amine conveyor belt lubricants) for comparison. The formulations in Table 4 are listed in wt%.

[0116] Table 4 Formulations

[0117]

[0118] For this example, a 0.2 wt % lubricant solution of the formulations in Table 4 was recirculated with water through a temperature regulated stainless steel / glass cylindrical storage tank connected to the recirculation system. This recirculation system consists of a pressure regulator and water pump connected in series with the storage tank through stainless steel pipes. The feed point for the recirculation system is at the bottom of the tank and water is sent back into the cylindrical tank through CIP nozzles located near the top of the tank. The pressure ...

Embodiment 3

[0123] Example 3 compares the ability of different lubricants to lubricate glass vials on stainless steel surfaces. For this example, a 0.2 wt% solution of the formulations in Table 4 was mixed with LUBODRIVE GLF commercially available from Ecolab Inc. (St. Paul, MN). TM and LUBODRIVE NF TM(a phosphate ester lubricant). For this example, the formulations were tested using a shorttrack test.

[0124] short track test

[0125] For this trial, a 600mL PET bottle of Mount Franklin Mineral Water was used as the PET container and two 373mL Pepsi Cans were used as jar containers and two 373 mL Victoria Bitter bottles were used as glass containers. For the test, the mass of the container is measured. One or more containers are then attached to the strain gauges by strings. Place the container and strain gage on the desired lubricated track and run the track for 30 seconds. The force is measured after 30 seconds.

[0126] The results of Example 3 are shown in Table 6.

Abstract

The invention relates to lubricant compositions, and methods especially as lubricants for the transport of glass, aluminum, and PET containers. The lubricant compositions contain a phosphate ester, an amine salt, and a nonionic surfactant.

Description

field of invention [0001] The present invention relates to lubricant compositions, and in particular methods thereof as lubricants for conveying glass, aluminum and PET containers (containers made of ethylene terephthalate homopolymers, copolymers and mixtures thereof) . The lubricant composition (hereinafter "composition") comprises a phosphate ester, an amine salt, and a nonionic surfactant. Background of the invention [0002] In the food and beverage industry, containers are usually transported by conveyor belts at very high speeds. These containers may comprise many different materials including metal, glass, paper such as treated and waxed paper, polymeric materials, and the like. During operation, the containers can rest on the conveyor belt for a certain period of time due to the support on the conveyor belt. When the containers are stopped, the conveyor usually continues to move. To aid in the smooth transport of the containers on the conveyor belt, the lubrican...
