[0022] First, a first embodiment of the synthetic resin container of the present invention will be described.

[0023] figure 1 and figure 2 It is an explanatory drawing showing the outline of the synthetic resin container of this embodiment. exist figure 1 middle, figure 1 (a) is the front view which shows the outline of the synthetic resin container of this embodiment, figure 1 (b) is the same side view. in addition, figure 2 yes figure 1 (a) A-A section view.

[0024] In addition, when the cross section of the container 1 is shown in figure, the wall thickness of the cross section is exaggerated in drawing.

[0025] The container 1 in this embodiment has a mouth 2 , a trunk 3 and a bottom 4 .

[0026] The mouth 2 is formed into a cylindrical shape, and on the side surface of the opening end of the mouth 2, screw threads for attaching the lid 5 formed as a threaded cap are provided as cap mounting means. Thereby, by attaching the cap body 5 to the mouth part 2 af...

Abstract

To minimize the reduction in internal volume due to flexural deformation and to prevent squirting and spilling of a contained liquid when a user grips a container, a grip part (6) which collapses toward the interior of the container and approaches the other side face is formed on at least one of the side faces opposing a body part (3) so that when a finger is placed on the grip part (6) while thecontainer is being opened or after the container is opened, the inner faces of the opposing side faces of the body part (3) are able to make contact with each other due to the flexural deformation caused by a gripping force acting on the grip part (6).

Description

technical field [0001] The present invention relates to a synthetic resin container that suppresses bending deformation when the container is held. Background technique [0002] Conventionally, it is well known to form a bottomed cylindrical preform using a synthetic resin such as polyethylene terephthalate, and then mold the preform into a bottle-shaped synthetic resin container by stretch blow molding or the like. , as a beverage container with various beverages as its contents. [0003] In recent years, such synthetic resin containers have been rapidly spread and permeated, and with the wide spread, there has been a strong demand for containers to be reduced in weight. Among them, for applications with a large capacity, an increase in weight due to an increase in the size of the container is regarded as a problem, and the cost disadvantages such as an increase in the amount of material resin used are also required to be improved. [0004] Therefore, in Patent Document 1...
