<p>PURPOSE:To deform only the inner layer when a bottle is deaerated to prevent the apparent deformation of the bottle, by providing freely separable inner layer and outer layer in a laminated bottle composed of both inner and outer layers and bonding both layers by one adhesive belt along the axial direction of the bottle. CONSTITUTION:A laminated bottle having a bottle opening 4 at the upper part of the shell is composed of the nylon layer 1 and the high density polyethylene outer layer 2 for instance. A pump for discharging the contents can be attached to the bottle opening 4. In this case, the inner layer 1 can be freely removed from the outer layer 2 and both layers 1, 2 are stuck to each other partly at the adhesive layer 3. This adhesive layer 3 is vertically provided from the bottle opening 4 to the bottle bottom 5 to form a belt at a part of the outer peripheral face of the inner layer 1 or the inner peripheral face of the outer layer 2. In this way, when the liquid contents is taken out and the inside is deaerated, the inner layer 1 is removed evenly from the outer layer and perfectly broken flat at the middle of bottle.</p> |
