<p>PROBLEM TO BE SOLVED: To provide a container which does not change in external shape as a whole even though the amount of contents becomes small and is free from becoming unsanitary with a liquid or the outside air infiltrated into a space between an external layer and an internal layer to form dew condensation. SOLUTION: The container is adaptable to partial recovery and partial disposal and has at least two layers including a shape-keeping external layer and a flexible internal layer. Both of the external layer and the internal layer are separably laminated together with dividing grooves making the external layer dividably formed in the direction wherein molding materials flow at the time of molding, and all of the dividing grooves are filled with the molding material the same as that of the internal layer while a coating layer is provided all over the outside of the external layer.</p> |
