In order to solve the above-mentioned problems, the present invention has the following features. That is, in a laminated bottle composed of at least two layers of an outer layer and an inner layer, the inner layer and the outer layer can be separated, and an adhesive layer is formed on at least a part between the inner layer and an outer layer adjacent to the inner layer. Then, the inner layer and the outer layer were adhered to each other, and a laminated bottle was obtained in which a polymerization cross section of the inner layer and the outer layer was exposed to the outside of the bottle.

In the present invention, the inner layer and the outer layer may be separated from each other, and any number of layers may be used as long as they are two or more layers. The inner layer to be peeled off may itself be a multi-layer. Further, the inner layer and the outer layer are adhered to each other at least in part by an adhesive layer. For example, an adhesive layer can be provided at the mouth between the inner and outer layers. In this case, the inner layer and the outer layer may be entirely adhered to each other in the mouth portion, but the inner layer and the outer layer may not be entirely adhered to each other in the body portion. However, the inner layer and the outer layer may partially adhere to each other as long as the peeling of the inner layer from the body portion is not hindered.

In the laminated bottle according to the present invention, after filling the contents,
When a long time has passed and the volume of the contents is reduced and the pressure in the bottle is reduced even in a sealed state, air is sucked in between the inner layer and the outer layer exposed to the outside due to the cross-section of these layers. The inner layer is easily separated from the outer layer. As a result, only the inner layer is easily shrunk and deformed, and no change is observed in the external shape of the bottle. In this case, even if the adhesive layer is formed between the inner layer and the outer layer, the air is inhalable because the inner layer and the outer layer are not completely sealed.
