In this example, the gas sealing portion is provided only in one side seal portion, but the gas sealing portion may be provided in both side seal portions. This will further increase the independence.

  And the diagonal seal part 9 is provided in the corner part of the other side seal part 7 and the top seal part 8, and the base part 10 of the plug 1 is pinched and sealed. A side wall portion 11 is integrally provided on the pedestal portion 10 toward the outside of the diagonal seal portion 9, and a pouring member 12 is attached to a tip end of the side wall portion 11. A pouring outlet 13 is provided at the tip of the pouring member 12.

As shown in (A) front view and (B) plan view of FIG. 2, the plug 1 has a pedestal portion 10 integrally connected to the lower end of the cylindrical side wall portion 11. Both the left and right ends of the pedestal 10 have an acute angle in a plan view, and the central portion has the same width as the side wall 11.

  At the upper end of the side wall portion 11, a pouring member 12 having a tip end portion formed of a substantially hemispherical outer shape protrudes. And the pouring outlet 13 is provided in the front-end | tip part of the pouring member 12 by one linear cut.

  The upper part of the plug 1 is shown in the upper longitudinal section of FIG. At the upper end of the side wall portion 11, an upper locking portion 14 extending in a ring shape is formed inside. The dispensing member 12 is formed of a film-like rubber with a tip portion having a substantially hemispherical outer shape. At the lower end of the pouring member 12, a pouring portion engaging portion 15 extending in a ring shape is provided outside. The pouring member 12 is inserted from the lower end of the side wall 11 and is inserted until the pouring portion locking portion 15 contacts the upper locking portion 14.

  Then, the locking ring 17 is fitted in the ring-shaped locking groove 16 provided below the pouring portion locking portion 15 on the inner surface of the side wall portion 11 to lock the pouring member 12. ing. The pouring member 12 is made of a film-like rubber, but at the portion of the pouring outlet 13 provided at the tip end thereof, the inside thereof is hemispherically depressed and the thickness is thin.

  Since it is like this, when the internal pressure is increased by pushing the bag 2 of the container body, the tip end of the pouring member 12 easily bulges out, the pouring outlet 13 provided by the cut is opened, and the pushing is stopped. Also, since the thickness of the outer portion around the pouring spout 13 is thick, the return force is strong and easily returns, and the spouting spout 13 provided by the cut is also closed as it was.

  In the plug 1, the wall thickness is reduced by allowing the inner part to be hemispherically depressed around the portion of the spout 13 provided at the tip end, but as in the plug 1a of FIG. The wall thickness may be gradually reduced toward the center spout 13 from the outside of the

  As a film mainly composed of a synthetic resin used for the bag 2, it is desirable to use a laminated film in which a base film and a sealant layer are laminated. This laminated film is used for the front film and the back film of the bag 2 and the bottom tape 3.

  As the base film, a biaxially stretched film of a resin such as nylon, polyester, or polypropylene is preferably used. Moreover, the vapor deposition film which vapor-deposited silica, an alumina, etc. to these biaxially stretched films can also be used.

  For the sealant layer, an unstretched film of a polyethylene-based or polypropylene-based resin is preferably used. For laminating the sealant layer, a dry laminating method, an extrusion laminating method, or the like is used.

  An intermediate layer can also be used between the substrate film and the sealant film. For the intermediate layer, a film similar to the substrate film can be used, and a resin film with high barrier properties such as ethylene vinyl alcohol copolymer can also be used. Moreover, metal foils, such as aluminum foil, can also be used.

  The pedestal portion 10 and the side wall portion 11 of the plug 1 are integrally molded. The resin used for the pedestal portion 10 and the side wall portion 11 is heat-sealed since the pedestal portion 11 is sealed by being sandwiched between the front film and the back film at the diagonal seal portion 9 of the bag 2, It is molded with a polyethylene or polypropylene resin used for the sealant layer and a polyethylene or polypropylene resin capable of heat fusion. Molding can be performed by injection molding or the like. Further, the locking ring 17 can be similarly molded of the same resin.

  The pouring member 12 of the plug 1 is made of rubber. Although rubber includes natural rubber and synthetic rubber, it is preferable to use synthetic rubber from the viewpoint of quality stability. Examples of synthetic rubbers include isoprene rubber, butadiene rubber, styrene butadiene rubber, chloroprene rubber, nitrile rubber, butyl rubber, acrylic rubber, ethylene propylene rubber, fluororubber, silicone rubber and the like.

  Among synthetic rubbers, fluorine rubber and silicone rubber are particularly preferable. In terms of cost, silicone rubber is more preferable. Since silicone rubber having a siloxane bond as a main skeleton is excellent in water resistance and chemical resistance, it is a liquid food or alcohol beverage in which taste is important, or a toiletry product or cosmetics having permeability such as surfactant or perfume. Can be used with confidence for the contents of

  The molding of the pouring member 12 with silicone rubber is not particularly limited, but injection molding, press molding, and transfer molding are preferably used. The hardness (JIS K6249) of the molded silicone rubber is preferably 40 to 70 degrees, more preferably 50 to 60 degrees. The elongation (JIS K7127) is preferably 300 to 800%, more preferably 400 to 700%.
