Laminated release container and method for manufacturing same

Abstract

Provided is a delamination container having excellent content dischargeability. The delamination container includes an outer layer and an inner layer. The inner layer peels from the outer layer and shrinks with reductions in contents. The outer layer consists of a single layer or multiple layers. At least one of innermost and outermost layers of the outer layer contains a lubricant.

1 . A delamination container comprising:
 an outer layer and an inner layer,   the inner layer is configured to peels from the outer layer and shrinks with reductions in contents,   the outer layer includes a single layer or a plurality of layers, and   at least one of innermost and outermost layers of the outer layer contains a lubricant.   
     
     
         2 . The delamination container of  claim 1 , wherein the outer layer comprises a plurality of layers and comprises a repro layer between the innermost and outermost layers. 
     
     
         3 . The delamination container of  claim 1 , wherein
 an outermost layer of the inner layer is formed of an EVOH resin, and   the innermost layer of the outer layer contains the lubricant.   
     
     
         4 . A method for producing the delamination container, comprising:
 extruding a molten multilayer parison having a multilayer structure corresponding to a layer configuration of the delamination container, and   molding the molten multilayer parison by rotary blow molding, wherein an outermost layer of the outer layer contains the lubricant.
