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

The present invention relates to a container consisting of a synthetic resin, the container having a bottom structure configured so that the deformation of the bottom due to a change in pressure within the container is uniform and gradual and so that the bottom structure has pressure reduction absorbing performance capable of reliably accommodating a large change in pressure within the container. A container consisting of a synthetic resin has, formed at the bottom thereof: an annular leg comprising an outer peripheral wall which continues from the barrel, a ground contact section, and an inner peripheral wall; and a raised bottom located on the inside of the inner wall surface of the leg at a position above the ground contact section. The container consisting of a synthetic resin is characterized in that the raised bottom protrudes further downward than the base of the inner peripheral wall of the leg, in that the raised bottom has spiral arc-shaped protrusions extending from the outer edge of the center section of the raised bottom toward the outer peripheral side, and in that arc-shaped recesses are formed between adjacent arc-shaped protrusions.

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...
