Abstract
Apparatus and a method for inserting flexible liners into container lids. The apparatus includes a piston and means for actuating the piston in a reciprocal path. Means are provided for supporting a container lid in a position substantially normal to the reciprocal path of the piston at one end thereof. The piston has means affixed to the end of the piston nearest the interposed liner for moving a flexible liner interposed between the piston and the container lid into the container lid and for urging the liner into a flat position within the container lid.

Apparatus for inserting a flexible liner into container lids comprising a piston, means for actuating said piston in a reciprocal path, means for supporting a container lid in a position substantially normal to said reciprocal path of said piston at one end thereof, means for interposing a flexible liner between said piston and said container lid and resilient means affixed to the end of said piston nearest said interposed liner for moving said interposed liner along said reciprocal path and for urging said flexible liner into a flat position within said container lid, said resilient means being a lip of resilient material extending outwardly from the periphery of said piston.
A method for inserting flexible liners into container lids comprising providing a piston moveable in a reciprocal path, supporting a container lid in a position substantially normal to the reciprocal path of said piston at one end thereof, interposing a flexible liner between said piston and said container lid, said piston including a resilient lip extending outwardly from the periphery of said end of said piston nearest said interposed liner and moving said piston in said reciprocal path so that said resilient lip urges said flexible liner into a flat position within said container lid.
