<p>PURPOSE:To obtain an integral container, which contains a plurality of contents, the levels to be requested of which are different from each other or which request functionalities different from each other to the container by a method wherein one compartment or a plurality of compartments are formed by multi- layered injection molding in a plastic container having a plurality of compartments. CONSTITUTION:The container has, for example, two compartments 1 and 2 connecting to each other with flanges 3. The compartment 2 is a single layer and made of plastic same as the flange 3. The other compartment 1 is made of two different materials and has three-layered constitution. Concretely, the surface layer is made of material same as the flange 3. The intermediate layer is made of material having specified functions such as lightproofness, oxygen gas barrier properties or the like. When no adhesion between the above- mentioned functional material and surface-forming material is present, adhesive bond is provided between both of them so as to allow to form five-layered structure made of three different materials. The above-mentioned container can be molded with a multi-layered injection molding device.</p> |
