ABSTRACT:
A squeezable laminated discharge container of the delaminatable type in which the layers can be easily broken away from each other comprises a first check valve fitted to the neck and has an opening in a bottom plate. The base cup comprises a second check valve, and is fitted tightly around the container bottom cylinder. In this discharge container, it is sought to secure stable and strong fitting and to maintain tight contact stably, between the container and the base cup.
