The present invention relates to laminated tube containers. A laminated tube container is conventionally known, which is made by rolling up a sheet made by laminating one or more synthetic resin layers on both sides of an aluminum foil, using this as the body, and providing a squeeze opening for squeezing. This sheet is made by laminating, for example, antistatic polyethylene, polyethylene, milky white polyethylene, polyethylene, paper, polyethylene, aluminum foil, polyethylene, ionomer, and polyethylene in this order from the outside. However, when a tube container whose body is made of this sheet contains strongly chemical contents such as toothpaste containing hinokiteol, hinokiteol permeates the synthetic resin layer and corrodes the aluminum foil, causing it to peel off. However, the inner polyethylene has the disadvantage of being colored. The present invention was made under these circumstances, and provides a laminated tube container in which the body is formed by rolling up a sheet made by laminating one or more synthetic resin layers on both sides of an aluminum foil. This is a chemical-resistant laminated tube container characterized by using a sheet in which the inner surface of aluminum foil is treated with an aluminum treatment agent and then a synthetic resin is laminated via a two-component reactive polyester adhesive. In the present invention, the aluminum treatment agent is
For example, it is known as an aluminum finishing agent, such as epoxy-phosphoric acid type, epoxy-
Processing agents such as phenol type and phenol-butyral type can be used. Furthermore, any synthetic resin can be used to layer the resin through the adhesive, and for example, polyethylene or the like can be used. Furthermore, the outer layer of the aluminum may have the same layer structure as the conventional tube container. Examples will be explained below. <Example 1> The surface of aluminum foil was coated with an epoxy-phosphoric acid treatment agent (MF#5 manufactured by Toyo Ink Co., Ltd.) using a cylinder with a plate depth of 15 to 20μ, and a two-component reactive polyester adhesive was applied. agent (manufactured by Toyo Morton Co., Ltd.)
AD503-35E) was applied at 2 to 3 g/m 2 , and a 90 μm thick polyethylene film was bonded thereto. The aluminum foil used had polyethylene, paper, polyethylene, milky white polyethylene, polyethylene, and antistatic polyethylene laminated in this order on the opposite side. The obtained sheet was rolled up with the side on which the polyester adhesive was applied inside, and a tube container was produced using this as the body. <Example 2> Example 1 except that an epoxy-phenol finishing agent was used as the aluminum treatment agent.
A tube container was prepared in the same manner. Toothpaste containing hinokiteol was stored in the tube containers of Examples 1 and 2 above and the conventional product, and left for two weeks at 40°C and 20% humidity to prevent corrosion of the aluminum foil and and polyethylene adhesive strength was measured. The results are shown in Table 1.

As mentioned above, the container of the present invention is resistant to chemicals such as hinokiteol because the synthetic resin is bonded with a two-component reactive polyester adhesive.
Furthermore, since the adhesive is used after aluminum is treated, its adhesive strength is excellent, and it is also excellent as a container for cosmetics, mustard, etc., as well as for polishing.
