<p><P>PROBLEM TO BE SOLVED: To provide a delamination container, for which a method for sealing a bottom off from the outside surely and easily at low cost is employed, and which requires less costs and has superior operability. <P>SOLUTION: A container body is blow molded from a cylindrical parison, and is composed of an outer layer and an inner layer laminated peelably on the outer layer to form an inner bag whose capacity is reducible. The container body has a cylindrical bottom part with a bottom face, on which a bottom seal part, which is crushed flat by a pinch-off part of a blow-split die and is formed along a parting line, is formed, and an air inlet for guiding in air between the outer layer and inner layer is formed on the outer layer. A cylindrical bottom cover with a bottom is fitted from below at the outside of the bottom part. Further, a cylindrical body made of a heat shrinkable synthetic resin is fitted airtightly at the outside of the part that covers from the trunk lower end of the container body to the cylindrical part of the bottom cover. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
