ABSTRACT:
A separable laminated container (A) of the present invention comprises an outer layer (1) made of synthetic resin and having an air suction hole (10) and an inner layer (2) made of synthetic resin and separably laminated on the inside of the outer layer, the inner layer having a portion previously separated from the outer layer just around the air suction hole. The air suction hole can be formed by driving a punch into the outer layer at a neck (4) of the separable laminated container from the outside, and punching just the outer layer leaving the inner layer behind. The portion of the inner layer previously separated from the outer layer may be left in the inwardly extended state. The inner layer is preferably made of synthetic resin having flextural modules of less than 10,000 kg/cm2.
