<p>PROBLEM TO BE SOLVED: To provide a vessel improved in safety, flexibility, transparency, resistance to heat, and appearance by using polymers for the construction of the inner walls and by providing weak seals on the opposing inner walls for the formation of plural chambers. SOLUTION: The inner walls of the above-stated vessel is built of a polymer composition of a polypropylene-base polymer and metallocene catalyst-base linear low-density polyethylene. The rate in weight of the two materials is set at 30:70 to 85:15. At a part of the opposed inner walls, weak seals for partitioning are provided for the formation of plural accommodating chambers. As for the polypropylene-base polymer, an ordinary polypropylene of a stereospecific structure, that is, an isotactic crystalline homopolymer or the like is used.</p> |
