Abstract
In a multilayer bottle having at least two layers including an outer layer and an inner layer according to the present invention, the inner layer and the outer layer adjacent thereto are separable from each other at a body of the bottle while the inner layer and the outer layer are adhered to each other at least a part thereof in order to prevent the deformation of the bottle due to the reduction of a pressure in the bottle. When the pressure in the bottle reduces due to the volatilization of a content in the bottle or due to the discharge of the content by a pump and the like, the inner layer is separated from the outer layer and is crushed in the form of a bag, so that the outer layer is not deformed at all.
