Stacking plastic cups and lids
Реферат: Nesting stacks of plastic cups or lids, from which individual cups or lids can be easily withdrawn, are produced by moulding the cups or lids with slightly different tools, and the carrying out stamping and stacking in such a manner that the adjacent cups or lidsin a stack have a sufficiently different shape to prevent jamming. The cups or lids can be withdrawn easily from a nesting stack, and jamming does not occur even in self service machines. The difference in the shape of the cups is not easily detected by a user.
