Abstract
Abstract A flap is inserted in a similarly shaped and sized tubular opening with the aid of a tool, slots in the flap being engaged by hooks on the tool and being entrained thereby. The tool is inserted into the opening with the flap, and upon withdrawal of the tool, the hooks automatically disengage from the slots so that flap remains within opening. The flap and the tubular opening constitute opposite ends of part of a disposable paper hat.
