20140174037 | CARTRIDGE DELIVERY SYSTEM UTILIZING FILM BAGS - A film pack cartridge includes an integrally molded synthetic resin face plate having a discharge opening therein and a nosepiece on one face extending about the opening, and a flexible synthetic resin bag has one end sealingly adhered to the other face of the face plate and about the discharge opening and with the other end of the bag being sealed. Two bags may be disposed side-by-side or one bag may be of annular configuration with a bag of circular configuration disposed therewithin. The cartridges are produced by mounting generally tubular synthetic resin bags on mandrels which are inserted into a mold providing a cavity about an end of said mandrels and bags configured to provide a face plate and nosepiece. Molten synthetic resin is injected into the cavity to form a face plate with the ends of the bags sealingly adhered thereto. The face plate has a discharge opening therein and a nosepiece about said opening aligned with the end of said bag. The pack and mandrels are removed from the cavity, the bags removed from the mandrels, and other ends of the bags are sealed. Flowable compositions are injected through the nosepiece and into the bags. | 06-26-2014 |
