ABSTRACT:
Disclosed herein is a container in which a mixture of resins having different melting starting temperatures is used as a heat-sealable layer. The heat-sealable layer is heat-sealed at two or more locations under different conditions so that at least one hermetic heat seal and at least one heat seal having easy-to-peel openability are formed to define plural compartments isolated from one another. The compartments can be filled with different materials. These materials are isolated from one another until immediately before use. Upon application, the heat seal having easy-to-peel openability is broken from the outside to permit mixing of the materials. The container is useful for foods, medical and pharmaceutical substances, and the like.
