Embodiment Construction

[0037] Now, preferred embodiments of the synthetic resin container of the present invention will be specifically described with reference to the accompanying drawings.

[0038] figure 1 A synthetic resin container 1 (hereinafter also referred to as a container 1 ) of the present invention shown in , includes a mouth 2 , a shoulder 3 , a main body 4 , and a bottom 5 . The body portion 4 includes an upper body portion 4a continuous from the shoulder 3, a lower body portion 4b continuous to the bottom, and a central body portion 4c positioned between the upper body portion 4a and the lower body portion 4b.

[0039] The central body portion 4c has three circumferential ribs 6, 6, 6 formed in parallel and kept at equal intervals to maintain the mechanical strength of the body portion and to maintain the shape of the body portion against Deformation caused by internal pressure. In addition, the outer peripheral surface of the main body except for the rib 6 is formed linearly in th...

Abstract

A synthetic resin container with a bottom structure in which a bottom portion uniformly and mildly deforms responsive to a change in the internal pressure, and exhibits pressure reducing / absorbing capability to reliably cope with even a large change in the internal pressure. The synthetic resin container forms, in the bottom portion thereof, an outer circumferential wall that is continuing from the body portion, an annular leg portion inclusive of a grounding portion and an inner circumferential wall, and a raised bottom portion positioned over the grounding portion on the inside of the inner circumferential wall of the leg portion, wherein the raised bottom portion is protruding downward beyond the root portion where the leg portion is continuing to the inner circumferential wall, a plurality of arcuate protuberances are formed in a spiral shape heading from the outer edge of the central portion of the raised bottom portion toward the outer circumferential side, and arcuate dents are formed among the arcuate protuberances that are neighboring each other.

Description

technical field [0001] The present invention relates to a container made of synthetic resin having a bottom that can absorb pressure. More specifically, the present invention relates to a synthetic resin container having a bottom structure that can be changed corresponding to changes in internal pressure. Background technique [0002] Since synthetic resin containers are light in weight and excellent in impact resistance, they have been widely used as containers for packaging various liquids. In particular, stretch-formed containers obtained by stretch-blow molding polyethylene terephthalate (PET) have a combination of transparency, gas barrier properties, light weight, impact resistance, and moderate rigidity. Containers have been widely used as containers for liquid contents and have replaced glass bottles currently used for containing contents such as condiments. [0003] In order to improve the preservability of the contents, hot-filled contents are widely accepted eve...
