  The present invention relates to a packaging bag with a cap, and more particularly to a packaging bag with a cap in which the plug is accommodated in the packaging bag.

  2. Description of the Related Art In recent years, packaging bags with plugs in which a plug is provided on a packaging bag using a laminated body in which paper or plastic film is laminated are on the market. All of these are exposed to the plug, and dust is attached to the plug during transportation, storage, or over-the-counter sales, or when handling a packaging bag with a plug. There is a problem that people's hands touch. In addition, when the contents are food, the contents may be put directly into the mouth from the spout part of the plug, which has a serious unsanitary problem in terms of hygiene. Further, depending on the contents, when gas barrier properties are required for the packaging bag with a stopper, the gas barrier property can be imparted to the packaging bag, but there is a problem of deterioration of the gas barrier property from the stopper. This is due to the resin used and structural factors.

  There is a proposal to give a gas barrier property to the plug. This is a proposal in which a gas barrier property is imparted to the spout part of the plug (Patent Document 1). In this, a member having a gas barrier property is attached to the inner surface of the spout part of the plug by insert molding. In this method, since insert molding is performed at the time of injection molding, there are problems of management such as positioning and adhesion of members, and there is a problem that productivity is lowered.

  In addition, there are proposals for a packaging bag with a cap that is housed in a packaging bag, prevents deterioration of gas barrier properties, and is excellent in hygiene (Patent Documents 2 and 3).

  In patent document 2, the packaging bag formed by sealing the peripheral edge portion is divided into two chambers by sealing the inner layer of the packaging bag, and a mouth provided with a plug between the inner layers of the sealing portion divided into the two chambers. It is a packaging bag with a stopper. That is, the plug portion is covered and sealed with a film. Patent Document 3 also covers and seals the plug with a film.

  In these packaging bags, a side seal portion of the film covering the cap portion is provided with a notch and an opening assist line (perforation or cut) formed by connecting from the notch. When opening, the front and back films are opened along the opening auxiliary line formed across the plug from the notch. However, since the opening assist line is provided across the plug portion, there is a problem that the plug portion is caught and cannot be opened successfully.
