Problems solved by technology

If excessive thinning is carried out, the bottle collides with the guide rail of the conveying device in the production line of filling and packing of the content liquid, or in the process of conveying and moving a case containing multiple bottles, or When the bottles collide with each other in the box, the side peripheral wall of the bottle body will be deformed into a bent shape due to the lateral load, until buckled, and cannot return to the original shape.

Abstract

Disclosed is a circular bottle body manufactured from synthetic resin, wherein circumferential depression rib shapes are created that are capable of increasing surface rigidity of the lateral circumference surface without impairing vertical buckling resistance or plasticity. The circular bottle body comprises a cylindrical opening part, a tapering conical shoulder part, a cylindrical trunk part, and a bottom part. A pair of circumferential depression ribs is formed at a predetermined height upon the trunk part, one above the other in close proximity, in a collapsed state, wherein the bottoms of the lateral cross-sections of the circumferential depression ribs are oblique to the central axis direction of the bottle body, and the direction of the obliquity of the upper circumferential depression rib is opposite to the direction of the obliquity of the lower circumferential depression rib.

Description

technical field [0001] The present invention relates to a round bottle body made of synthetic resin. Background technique [0002] Bottles made of synthetic resin obtained by biaxial stretch blow molding of polyethylene terephthalate (hereinafter referred to as PET) resin or the like are widely used for beverages and the like. Patent Document 1 describes a circular bottle having a cylindrical body. Figure 10 The bottle body described in the embodiment of this patent document 1 is shown, but this bottle body 101 is a circular PET resin bottle body formed by biaxial stretching blow molding, and is a so-called PET bottle. 102 , the shoulder 103 , the body 104 and the bottom 105 are formed, and six decompression absorbing panels 112 are recessed and formed on the peripheral wall of the body 104 so as to be surrounded by the stepped portion 111 . In addition, peripheral groove ribs 114 are disposed on the upper end and the lower end of the body portion 104 . [0003] The decom...
