| titleOfInvention | Process for closing a flexible receptacle and closed receptacle |
| abstract | To provide a hermetic seal for flexible receptacles such as plastic bags, pouches, or casings, the outside of the mouth (11) of the receptacle is coated with a cold-flowing resin so that when the receptacle is filled and its mouth (11) gathered under pressure the resin will cold flow and fill the voids in the gathered folds. Preferably, the end of the gathered mouth (11) is trimmed and then high pressure is applied to cause the resin (10') to exude from the trimmed end. Next, a moulding plunger (9) is used to press the exudate into a smooth surface whereby a fused cap of resin is formed hermetically closing the bag's mouth (11). As an alternative, a clip or band can be placed around the gathered end under sufficient pressure to cause cold flow of the resin thereby sealing the voids. |
