ABSTRACT:
A quick pressure reducing apparatus is used in vacuum packing of clothing, food, or the like. In order to quickly shift the interior of a preservation bag from the atmospheric state to a pressure reduced state, a reservoir tank is provided which is connected to a rotary pump functioning as a vacuum pump. By establishing communication between the reservoir tank and the preservation bag via an adapter, the internal pressure of the preservation bag can be sufficiently reduced. The adapter has a retractable communicating tubular member so as to smoothly reduce the internal pressure of the preservation bag. The adapter is inserted into the opening portion of the preservation bag whose internal pressure is to be reduced, thereby establishing communication between the preservation bag and the reservoir tank via the communicating tubular member. The opening portion of the preservation bag, together with the inserted adapter, is held between the upper and lower holding members. The communicating tubular member, which has a number of small holes formed at its forward end portion, is projected from the adapter into the preservation bag by a drive mechanism. Accordingly, the internal pressure of the preservation bag can be quickly reduced while preventing the opening edge portion of the preservation bag or the like from closing the communicating tubular member.
