By improving heat resistance, so-called hot filling is possible. It is also used in the field of packs, but after it is hot-packed and hermetically sealed, when it is cooled, a reduced pressure is generated in the bottle, and due to this generated reduced pressure, inward pulling force against the bottle wall portion causes meat Inward bending deformation (generally referred to as decompression deformation) occurs in the thinnest body portion, and this deformation causes a problem that the commercial value is significantly deteriorated.

There was a dislike that some of the panel walls would be deformed convexly, and some panels would not be deformed normally under reduced pressure, resulting in a poor bottle appearance.

It is preferable that the parison is obtained by blowing a pressure fluid into the parison, blow-molding it, and taking it out of the mold.

A plastic bottle is characterized in that a plurality of sets are arranged on the outer periphery of the bottle with the pillar portion 3 interposed therebetween.

好ましい。As shown in FIG. 2, the decompression absorption panel 2 is composed of a vertically elongated concave surface 21 and a thin column portion 22 which are curved inward, and two vertically elongated concave surfaces 21 are arranged on both sides of the thin column portion 22. Has become. The thin column portion 22 may be formed slightly inward of the outer peripheral surface 11 of the bottle as shown in FIG. 2, or may be formed on the same surface as the outer peripheral surface (not shown). It is preferable that the pressure reducing absorption panel 2 is formed over the entire length and can reinforce the reduced pressure absorption panel 2 against the stress in the vertical direction.

As shown in FIG. 1, eight sets are arranged at appropriate intervals over the entire circumference of the upper wall surface of the bottle body 1, and the thick column parts 3 are arranged in between. The thick column portion 3 is flush with the outer peripheral surface 11 of the bottle.

吸収パネル２の不定変形が抑制される。Since each of the decompression absorption panels 2 has two vertically long concave surfaces 21 and a thin column portion 22 arranged adjacent to each other, it has a high strength against a stress in the vertical direction, and thus has a convex shape against an unbalanced load at the time of loading. Deformation is unlikely to occur, and since each decompression absorption panel 2 is arranged with the thick column portion 3 in between, the stress is equalized over the entire circumference of the wall surface, so indefinite deformation of each decompression absorption panel 2 during decompression deformation is suppressed. To be done.

Since it is a plastic bottle characterized by being arranged, indefinite deformation of the bottle is prevented not only in the hot packing of the contents or in the subsequent cooling process, but also indefinite deformation of the decompression absorption panel itself is always maintained. It can be maintained in a good condition.
