Abstract

PURPOSE:To prevent the layer separation of the body part of a container and the loss of metallic luster and gas-barrier property of the container by forming this container of a laminate material having the innermost layer constituted of a low permeable, heat-sealable polyester resins and the gas-barrier intermediate layer constituted of a thin film consisting of inorganic compound. CONSTITUTION:In a laminate tube container 1, since the innermost layer in contact with its contents of a laminate material 100 for forming the body part of the container is constituted of a heat-sealable polyester resin 115 difficultly permeable to the contents, the permeation of the contents is extremely lessened as compared to the conventional innermost layer constituted of polyethylene and the penetration of the contents to a gas-barrier layer in an intermediate layer is restrained in terms of quantity and time. Since the gas-barrier layer in the intermediate layer of the laminate material 100 is constituted of a thin film 114 consisting of inorganic compound formed on the one side of a thermoplastic resin film, the laminate tube container is free from corrosion due to penetration of the contents thereinto unlike a gas-barrier aluminum foil layer formed in the conventional laminate tube container.

As described above, the conventional laminated tube container has the aluminum foil layer in the intermediate constituent layer of the laminated material of the body when the gas barrier property is required, In addition, the innermost layer was provided with a polyethylene layer in order to facilitate heat fusion of the side seal of the body and the end seal of the bottom. Therefore, in the case of a particularly alkaline and highly permeable content, the content penetrates into the polyethylene layer of the innermost layer, and further the content gradually penetrates into the intermediate constituent layer over time, and finally, The contents sometimes came into contact with the aluminum foil in the intermediate constituent layer. Then, the aluminum foil may be corroded by the contents, resulting in delamination (delamination), loss of metallic luster, loss of gas barrier property, and the like. The present invention provides a laminated tube container in which the contents hardly penetrate into the innermost layer, and even when the contents reach the gas barrier layer by permeation, the above accidents in the conventional laminated tube container due to corrosion of the contents do not occur. Is provided.

In the laminated tube container of the present invention,
Since the innermost layer of the thermoadhesive resin that comes into contact with the contents of the laminated material that forms the body is a polyester-based thermoplastic resin that is difficult for the contents to penetrate, the innermost layer uses conventional polyethylene for the permeation of the contents. It is extremely small compared to the above, and the permeation of the content to the gas barrier layer in the intermediate constituent layer is quantitatively suppressed,
It is also delayed in time.
