Folded end construction for food sauce dispensing cartridges.

摘要

An end disk construction and connection for food sauce dispensing cartridges and other food containers. An end disk through which food sauce may be dispensed is fitted in the dispensing end of a cartridge that holds the sauce. The disk initially has a projecting peripheral skirt which fits against the side wall of the cartridge. The end portion of the cartridge wall is crimped inwardly to fold the skirt into a lip which is doubled over on the peripheral area of the disk. The flange formed by the inwardly folded wall portion encloses the lip and its raw edge to isolate the edge from the food sauce. A bond is effected between the disk and the cartridge wall and flange by thermoplastic coating on the disk and cartridge body which is heated during the crimping process.
