    (54) Breakaway closure for dispenser


    (57) A cartridge type dispenser for holding mayonnaise based sauces and the like. A tubular container (10) has a dispensing outlet on its bottom and a top rim (16) formed by a downturned lip (18). The container top is covered by a lid (22) having a wall (28) provided with a wiping rib (30) that acts against the inside surface of the container wall (14). A flange (36) which spans the rim (16) is joined to the wall (28) of the lid (22) along a perfora­tion line that allows the flange (36) to be torn away. A peripheral skirt (40) on the flange (36) has a locking rib (44) which mechanically interlocks with the lip (18) of the container (10) to lock the lid (22) in place. The flange (36) and skirt (40) have a frangible tear strip (46) for initiating severance of the perforation line. When the perforation line has been torn, the lid (22) is released from the container (10) and can be pushed by a dispensing gun into the container (10) to dispense its contents.
