Document Type and Number:
Japanese Patent JP7275603
Kind Code:
B2
Abstract:
To provide a tube container that is configured so that smooth extraction of contents can be suppressed from being restricted after the container is unsealed, while securing sealability and gas barrier performance until the container is unsealed first.SOLUTION: The tube container includes a cylindrical trunk part which can store contents and a pour-out port part attached to the other end of the trunk part, which has an opening scheduled part and a peripheral edge around the opening scheduled part. The pour-out port part comprises a first region in which an inner peripheral surface near the other end of the trunk part is made adhere across the whole circumference of a surface outside of the tube container of the peripheral edge part, a second region in which a gas barrier film is arranged on a surface inside the tube container, and an annular half-cut part. The trunk part is formed using a laminate material including the gas barrier layer. The first region and the second region are made adhere and attached to the pour-out port part so that the gas barrie layer and the gas barrier film overlap with each other when viewed from a normal direction at each position in a third region, in the third region ranged across the whole circumference of the peripheral edge part of the pour-out port part.SELECTED DRAWING: Figure 1
