<p>PROBLEM TO BE SOLVED: To provide a composite container capable of reducing the volume of the content in the container during or after use, and capable of easily and separately collecting a container body and an external cylinder after use. SOLUTION: A composite container 10 comprises a container body 12 having an expandable body part 14 and an external cylinder 16 to surround the whole body part of the container body, a part of the external cylinder 16 is connected to the other part of the container body adjacent to the body part 14, the external cylinder is divided into a plurality of annular parts 40 along the expansion/ contraction direction of the body part 14 by at least one first weakened part 36, and at least one second weakened part 38 extending so as to be across the first weakened part 36 is provided. In this constitution, the external cylinder can be easily and locally cut off along the weakened part 36, and its length can be reduced. Thus, the container body can be compressed thereby.</p> |
