PROCESS AND APPARATUS FOR FABRICATING A CONTAINER LID WITH AN INWARDLY FOLDED RIM

摘要

The present invention discloses a method and apparatus for fabricating a novel lid (31) for use in frozen dessert containers. The apparatus has an interchangeable mandrel for wrapping a strip (303) to form a rim of the lid to a predetermined configuration such as a super-ellipse. The invention allows for registered offset printing of the rim of the lid. The invention also allows for use of a single material for an entire frozen dessert container. The lid manufactured from the process and apparatus may be composed of a fiberboard material with a polyethylene coating thereon. The process and apparatus allows for the cost-effective fabrication of a frozen dessert container having a non-circular cross-section.
