Abstract: An improvement in a device for advancing an end portion of a strip of heat sealable film along a path from a cartridge to an applying station, sealing the end portion across the lip of a cup and severing the end portion from the strip of film. The device includes a perforating member which cooperates with a support surface in the cartridge before the end portion of the film is advanced to the applying station to perforate around a small portion of the film. The applied film can then be separated along part of the perforations and the small portion can be bent aside to provide an opening through which a drinking straw can be inserted into the cup.

Abstract: A device for applying lengths of a heat sealable film over the open ends of cups. The device includes means which engage the end of a supply length of the film which is coiled in a cartridge, pull a predetermined length of the film from the cartridge, move the cup and predetermined length of film into engagement, heat fuse the film to the lip of the cup, and cut the fused length of film from the supply length at the cartridge.
