Abstract

Dispenser apparatus and method for dispensing putty-like material utilizes a plastic bag as the container for the putty-like material to facilitate shipment and storage of the material and provide for ease of refilling the dispenser with additional material. The apparatus includes an open top container mounted on a bottom support plate with valved outlet for receipt of the bag of putty-like material. In one form of the invention, a completely sealed bag of the putty-like material may be inserted into the container through the open top which is then closed by a top closure plate. The bottom of the plastic bag is then punctured by inserting a sharp instrument through the valved outlet to provide a passage therein through which the putty is selectively dispensed when the valve is moved to the open position and pressure is applied to the container contents as by a push plate within the container driven by an air cylinder mounted on the top closure plate. In another form of the invention, the bag is made of sufficient length to permit one end of the bag to be folded over the top of the container after the bag has been opened and before the top closure plate is attached to form a cuff to retain the bag in place during dispensing of the contents therefrom. The container contents may be pressurized either by placing a putty follow plate in the bag and admitting pressurized air directly into the container, or by urging a push plate against the container contents as by actuation of an air cylinder, as before.
