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.
An apparatus for dispensing putty-like material comprising a hollow, open ended dispenser cylinder, a bottom support plate for said cylinder substantially to close off the bottom opening therein, said support plate having an outlet passage, a dispensing valve for opening and closing said outlet passage, said dispensing valve when moved to the open position having a valve passage in vertical coaxial alignment with said outlet passage, a flexible plastic-like bag containing the putty-like material adapted to be lowered into said cylinder, said bag having a bottom of said flexible plastic-like material which rests on said support plate and covers said outlet passage after lowering of said bag into said cylinder, said dispensing valve when in such open position permitting the insertion of a rod-like device through said outlet passage and said valve passage for puncturing said bottom of said bag to provide an outlet aperture in said bag in vertical alignment with said valve passage and said outlet passage in said support plate, a push plate in said cylinder including means for contacting the peripheral extent of said cylinder for vertically downwardly directed wiping movement therealong, a top closure plate for said cylinder, and means for urging said push plate downwardly within said cylinder to pressurize the putty-like material within said cylinder, so that when the dispensing valve is moved to the open position, the putty-like material will be dispensed from said apparatus.
A method of dispensing putty-like material comprising the steps of removing a top closure plate from an open top cylinder, lowering a flexible plastic-like bag filled with putty-like material into such open top cylinder so that the bottom of such bag which is also made of such flexible plastic-like material rests on a support plate and covers an outlet passage in the support plate at the bottom of such cylinder thereof, opening a valve connected to such outlet passage, such valve when open having a valve passage in vertical coaxial alignment with such outlet passage, inserting a rod-like device through such outlet passage and such valve passage to puncture the bottom of the bag in axial alignment with the outlet passage and valve passage providing an opening in the bottom of the bag in fluidic communication with the valve passage and outlet passage for discharge of putty-like material, removing the rod-like device from the outlet passage and valve passage, closing such valve, replacing such top closure plate on such cylinder, and urging a push plate downwardly within the cylinder to pressurize the putty-like material within the bag, whereby upon movement of the valve to an open position, the putty-like material will be dispensed through such outlet passage.
An apparatus for dispensing putty-like material comprising a dispenser cylinder having a bottom closure member containing an outlet passage, a dispensing valve for opening and closing said outlet passage, said dispensing valve when moved to the open position having a valve passage in vertical coaxial alignment with said outlet passage, a flexible plastic-like bag containing the putty-like material adapted to be lowered into said cylinder and supported by said bottom closure member, said dispensing valve when in such open position permitting the insertion of a rod-like device through said outlet passage and said valve passage for puncturing said bottom of said bag to provide an outlet aperture in said bag in vertical alignment with said valve passage and said outlet passage in said bottom closure member, a push plate in said cylinder, a top closure member for said cylinder, and means for urging said push plate downwardly within said cylinder to pressurize the material within said cylinder, so that when the dispensing valve is moved to the open position, the putty-like material will be dispensed from said apparatus.
A method of dispensing putty-like material comprising the steps of placing a flexible plastic-like bag filled with putty-like material into an open top cylinder having a valve dispenser in fluid communication with an outlet passage in the bottom of such cylinder, opening a valve connected to such outlet passage, such valve when open having a valve passage in vertical coaxial alignment with such outlet passage, inserting a rod-like device through such outlet passage and such valve passage to puncture the bottom of the bag in axial alignment with the outlet passage and valve passage providing an opening in the bottom of the bag in fluidic communication with the valve passage and outlet passage for discharge of putty-like material, removing the rod-like device from the outlet passage and valve passage, closing such valve, and urging a push plate downwardly within the cylinder to pressurize the putty-like material within the bag, whereby upon movement of the valve to an open position, the putty-like material will be dispensed through such outlet passage.
