品が空気中の酸素により酸化酸化され、商品価値が著し
く低下してしまうという問題があった。In the above-mentioned conventional paper container with a spout plug, the container itself has gas barrier properties, but since the spout plug is an integral injection molded product of synthetic resin such as polyethylene, it does not allow gas to permeate through the spout plug. As a result, there was a problem in that the contents were oxidized by oxygen in the air, resulting in a significant decrease in commercial value.

is a cross-sectional view of a paper container (B) containing aluminum foil (a).
It is shown attached to the opening. This spout stopper (A) is integrally molded from a synthetic resin such as polyethylene, and closes the opening with a flange (1) attached to the periphery of the opening of the paper container (B) by a fixing means such as an ultrasonic seal. A cylindrical spouting part (3) is provided above the continuous part, and a screw (4) for attaching a cap (not shown) is attached to the outer periphery of the spouting part (3). is provided. Further, a thin-walled part (5) of a desired shape for opening is formed on the upper surface of the top wall part (2), and a tension ring (6) is continuously provided within the thin-walled part (5). ing.

It is coated with a synthetic resin (7). When coating with the gas barrier resin, the back surfaces of the flange portion (1) and top wall portion (2) of the injection spout plug (A) are subjected to corona treatment by the method of the present invention. A frame treatment is applied in advance, and then polyvinylidene chloride, etc., which is a gas barrier resin (7), is applied to a thickness of several chromes. As with the conventional spout stopper, by pulling up the tension ring (6), the thin wall portion (5) is cut and at the same time, the gas barrier resin (7) is removed and opened.
