−１０２８５６号公報に開示されている。2. Description of the Related Art Conventionally, an upper body has a plurality of circumferential concave grooves in a horizontal direction, and a lower body has a plurality of vertically long reduced pressure absorbing panels arranged in the circumferential direction. A PET resin bottle in which a columnar portion is erected between the surfaces and a central circumferential groove is provided in the circumferential direction between the upper body and the lower body of the PET resin bottle, for example,

垂直圧縮強度が向上されている。[0003] Such a bottle body has a moderate resistance provided by a horizontal concave groove provided in the upper body to suppress deformation due to an external force acting from the lateral direction. The reduced pressure absorption panel surface absorbs the reduced pressure deformation,
The columnar portions erected between the panel surfaces improve the strength to withstand a load from above generated during capping or the like, that is, the vertical compressive strength.

た。これは、主としてその中央周溝の深さに関係するも
のと考えられる。However, in the above-described conventional bottle body, buckling occurs in the central circumferential groove due to a load from above during capping or transportation, or deformation due to an external force in the lateral direction. Could occur. This is considered to be mainly related to the depth of the central circumferential groove.

発生し、局部的な変形が発生しやすくなる。Therefore, for example, if the depth of the central peripheral groove is increased, the body becomes less likely to be deformed into an ellipse, and the vertical compressive strength is improved. Stress concentration occurs between the parts and around the upper part of the panel surface, and local deformation is likely to occur.

方向に作用する力を吸収・緩和することができる。On the other hand, when the depth of the central circumferential groove is reduced, the body tends to be deformed into an elliptical shape with respect to the vertical compressive force, so that the vertical compressive strength is reduced. In this case, since the amount of deformation into an ellipse becomes large, the force acting in the lateral direction can be absorbed and reduced.
