RESIN TUBE CONTAINER AND PREFORM THEREOF

摘要

PROBLEM TO BE SOLVED: To allow even a resin tube container formed by drawing and blow- molding to be used as it is as a bottomed container without requiring secondary processing similarly to a normally formed packaging container. SOLUTION: The resin tube container 1 has a bottomed barrel 3 which is drawn and blow-molded to be thin to connect with a mouth 2. A connected region between the barrel 3 and the mouth 2 is formed on a shoulder 5, and the barrel is flatly formed to be a tapered wedge together with a bottom face 4. Its preform 11 has a bottomed barrel 13 integrally formed in connection with a mouth 12. A connected region between the barrel 13 and the mouth 12 is formed on a concentric extending rim 15, and a peripheral wall of the barrel is formed to be thicker than the mouth 12. The barrel 13 is taperingly inclined to a bottom face 14 formed as a flat bottom thinner than the peripheral wall of the barrel and flatly formed into a wedge with an elliptic or oval cross section. The bottom face 14 is formed to be a flat bottom thinner than the peripheral wall of the barrel.
