Abstract

PROBLEM TO BE SOLVED: To introduce ambient air efficiently through an ambient air introducing hole provided at a container mouth, by forming a long groove extending along a parting line in a flat bottom wall of a container bottom, forming a bottom seal part on the flat bottom wall of the container so that the ends of the bottom seal part are not projected therefrom, and providing an adhesive layer for adhering to the bottom seal part and sealing it. SOLUTION: An adhesive layer 15 covering a bottom seal part is formed in a long groove 12, and this machining is executed after a superposed and separable container is produced by blow molding. A hot-melt adhesive whose material is the same as that of an outside layer 2 is used as an adhesive and is cast into the long groove 12. When a content liquid is poured out by a pump dispenser, ambient air is introduced through an ambient air introducing hole 7, whereby an inside layer 3 is shrunk and deformed. At the time, since the bottom seal part 13 adheres to and is sealed by the adhesive layer, ambient air can be introduced efficiently through the ambient air introducing hole 7 provided at a container mouth 5 without being introduced from the bottom seal part 13.

However, in the case of a laminated peeling container, in order to enhance the releasability between the outer layer and the inner layer, a resin having low adhesiveness must be used. There is a problem that a slit is generated in the seal portion due to delamination. Therefore, it has been proposed to form a welding ridge on the pinch-off portion (Japanese Patent Publication No. 6-102).
No. 076), it was difficult to weld only the outer layer depending on the resin, so that the generation of slits could not be prevented.
