<p>PURPOSE:To obtain a tubular container provided with a decomposable property as a whole, by making the tube shell to be a monolayer or a laminate of decomposable material and using a decomposable plastic material for a mouth molding. CONSTITUTION:A tubular container 1 is provided with a mouth molding 3 having a mouth 3a to pour the contents and a tube shell 2 adjacently fixed to the shoulder 3b of the mouth molding 3. The tube shell 2 is a monolayer or a laminate made of a decomposable material and the mouth molding 3 is a molding made of a decomposable plastic material. For instance, a barrier layer 50 is laminated on a plastic layer 11a at the inside of the container and further, an outermost layer plastic layer 11b is provided on the barrier layer 50 for the tube shell 2. The plastic layers 11a, 11b are made of decomposable plastics, especially decomposable polyethylene resin, decomposable polypropylene resin, or polyvinyl alcohol or cellophane. Since the tubular container is made of a decomposable material in this way, even if they are left to stand, they are spontaneously decomposed.</p> |
