Claims

[Claims for Utility Model Registration] 1. Comprising a bag body and a stopper attached to the bag body, the stopper has seal portions at both ends in the longitudinal direction of two rectangular flexible synthetic resin films. By adhering them to each other, an outer opening that opens to the outside of the bag body and an inner opening that protrudes toward the inside of the bag body are formed, and seal portions at both end portions are formed. A pipe can be inserted between these spaces to suck out the air inside the bag body.
There is a slight margin, and the two stacked films are held together by the ends of the seals at both ends on the inner opening side, or by the seals that protrude slightly into the pipe insertion passage from a position slightly above the inner opening. A vacuum packaging bag characterized by being adhesively bonded to form a pipe insertion stopper. 2 Comprising a bag body and a stopper attached to the bag body, the stopper is inclined inward from the top to the bottom of both end portions with respect to the longitudinal direction of two rectangular flexible synthetic resin films. An outer opening that opens to the outside of the bag body and an inner opening that protrudes toward the inside of the bag body are formed by mutually adhering the seal portions. The angle of inclination should be such that the distance between the seals on the outside opening allows for the insertion of a pipe that sucks the air inside the bag body, and the distance between the seals on the inside opening must be enough to allow the insertion of a pipe that sucks the air inside the bag body. The suction port of the pipe that is intended to suck in the pipe is angled to form a gap that stops at a position slightly above the inner opening, so that the above-mentioned stopping position effectively prevents the pipe from being inserted. A vacuum packaging bag according to claim 1 of the utility model registration claim.
