PROCEDURE FOR FORMING JOINTS IN CONTAINER LIDS |
| abstract |
Procedure for forming gaskets in lids for containers, whose lids are made of a polyolefin resin characterized in that it comprises the steps of introducing a plastisol compound such as one composed of 100 parts of vinyl chloride polymer 50 to 80 parts of plasticizer in the cap, forming the plastisol into a gasket of the desired configuration, the cap being formed of an olefin polymer such as one selected from; polypropylene, and polyethylene which is practically insensitive to thermal activation by radiofrequency electrical energy, and the plastisol being composed of vinyl chloride polymer and a plasticizer having a dielectric constant between approximately 6 and 8 and a loss factor between approximately 2 and 25; melting the plastisol into the cap by dielectrically heating the plastisol with exposure to a radio frequency electrical energy source and then allowing the molten plastisol to cool to form the gasket. |
