Abstract
A laminated bottle including a bottle body having at least two layers, an outer layer and an inner layer, in order to prevent the outside of the bottle from collapse under a reduced pressure inside the bottle. The inner layer of the bottle body and the outer layer adjacent the inner layer are made to be freely peelable from each other, with the inner layer and the outer layer being at least partially bonded together at bonding band and locking portion locations. As the inner layer is peeled away from the outer layer and collapsed in a bag-like configuration upon vaporization or emptying of the bottle contents, deformation of the outer layer is not likely to occur.
