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.

Embodiment Construction

[0043] Hereinafter, an embodiment of the synthetic resin circular bottle body of the present invention will be described based on examples and with reference to the drawings.

[0044] figure 1 , figure 2 Shows an embodiment of the round bottle body of the present invention, figure 1 Main view, figure 2 for figure 1 The longitudinal cross-sectional view of the side peripheral wall in the area enclosed by the two-dot chain line in the figure shows the longitudinal cross-sectional shape of the upper and lower pair of peripheral groove ribs 7a and 7b.

[0045] The bottle body 1 is a two-axis stretch blow-molded product (PET bottle) made of PET resin. It has a mouth tube portion 2, a tapered shoulder portion 3, a cylindrical body portion 4, and a bottom portion 5. The total height is 206mm , A circular bottle with a width of 68mm and a capacity of 500ml.

[0046] In addition, on the side peripheral wall of the cylindrical body portion 4, six decompression absorption plates 12 that ar...

Abstract

A synthetic resin round bottle having a shape of the peripheral groove ribs that can increase the plane rigidity of the peripheral sidewall, without lowering the buckling strength in the vertical directions and the moldability of the bottle, including a round bottle having a neck, a tapered cylindrical shoulder, a cylindrical body, a bottom, a pair of peripheral groove ribs disposed at certain height positions of the body and formed in groove shapes, with one groove over the other groove in proximity to each other, where bases of these peripheral groove ribs are inclined relative to the direction of central axis of the bottle in a vertical sectional view, and the incline of a rib base for the upper peripheral groove rib has a direction opposite that of the incline of the rib base for the lower peripheral groove rib.

Description

Technical field [0001] The invention relates to a round bottle made of synthetic resin. Background technique [0002] Synthetic resin bottles made by biaxial stretch blow molding made of polyethylene terephthalate (hereinafter referred to as PET) resin are widely used in beverage applications and the like. Patent Document 1 describes a circular bottle body having a cylindrical body part. Picture 10 The bottle body described in the Examples of Patent Document 1 is shown, but the bottle body 101 is a round PET resin bottle body formed by two-axis stretch blow molding. It is a so-called PET bottle. 102, the shoulder portion 103, the body portion 104, and the bottom portion 105 are formed, and six pressure reduction absorption plates 112 are recessed and formed on the peripheral wall of the body portion 104 so as to be surrounded by a step portion 111. In addition, circumferential groove ribs 114 are arranged at the upper end and the lower end of the body portion 104. [0003] The de...
