The chuck provided in such a storage bag is composed of a convex chuck member and a concave chuck member fitted to the convex chuck member. The convex chuck member is provided on the inner surface of one bag surface, A chuck member is provided on the inner surface of the other bag surface, and by fitting the convex chuck member and the concave chuck member, the storage bag is sealed and the fitting between the convex chuck member and the concave chuck member is released. By doing so, it can be opened and the stored items can be taken out. Further, by fitting the convex chuck member and the concave chuck member together, the remaining stored item can be sealed again.

  In the storage bag as described above, in order to release the fitting between the convex chuck member and the concave chuck member and open the bag, after expanding both bag surfaces located on the opening side from the portion where the chuck is provided The bag surfaces are gripped by the thumb and the index finger, respectively, and the fitting is released by pulling the convex chuck member and the concave chuck member in the direction of separating them.

  However, in the storage bag as described above, since the width of the bag surface located closer to the opening than the chuck is small, it is not easy to expand both bag surfaces. Therefore, an articulating tool that facilitates the expansion of both bag surfaces has been proposed (see, for example, Patent Document 1).

  The bite includes a male member having a belt-like base portion and a male bite portion projecting in parallel to the base portion, a belt-like base portion and a female biting into the male bite portion and projecting in parallel to the base portion. A synthetic resin occlusion device comprising a female member provided with a mold occlusion portion, wherein the male occlusion portion or the female occlusion portion of the base of the male member or the female member is flush with the female occlusion portion. It is characterized by comprising a plate-like protrusion that protrudes parallel to the male occlusion part or the female occlusion part and higher than the protrusion height of the male occlusion part or the female occlusion part. The projecting portion always keeps the space between the base portions of the male member and the female member expanded.
