Abstract
In the manufacture of extra thin walled plastic containers the tail flash formed during the molding operation is spaced from the container proper by molding one or more standoff projections into the flash. This maintains the tail flash in an appropriate relationship relative to the container until it can be severed by a shearing mechanism. The projections are formed in the tail flash by providing male and female projection elements in the mold. In the absence of such standoffs, the tail flash will come in contact with the container while still sufficiently hot enough to adhere thereto.
