が強度的に安定し最も好ましい。In the present invention, as shown in FIG. 1, a gripping constriction 2 having a circular cross section is formed substantially all around the center of the cylindrical body of the bottle main body 1, and the minimum diameter of the constriction 2 The length a is greater than the length b of the upper surface wall 22 on the upper side of the minimum diameter portion, and the upper surface wall 22 is steeply inclined. The lower surface wall 23 on the lower side of the minimum diameter portion 21 is gently curved outwardly. It is formed in a shape. In the present invention, the plastic bottle is composed of a plug portion 11, a shoulder portion 12, a torso upper portion 13, and a torso lower portion 1.
4 and a bottom portion 15, and a constricted portion 2 is formed substantially at the center of the body. The constricted portion 2 needs to have a circular cross-section, but the cross-sectional shape of the upper portion 13, the lower portion 14, and the like may be quadrangular, octagonal, or the like. It is most preferable that the cross section be the same as that of No. 2 because the strength is stable.
【００１０】くびれ部２を全周にわたり形成したので、
このくびれ部２をどの方向からも把持することができ
る。Since the constricted portion 2 is formed over the entire circumference,
The constricted portion 2 can be gripped from any direction.

持力によっても変形しにくいので、取扱いが安定する。The constriction 2 has a circular cross section, and the upper wall 2
The shape is reinforced by the lower wall 2 and the lower wall 23, so that it is hardly deformed even by the gripping force, so that the handling is stable.

湾曲状とすると、特に掌になじみ易いので好ましい。According to the present invention, the length of the minimum diameter portion 21 is large and the top wall 22 is steeply inclined, so that a large holding space can be taken and fingers can easily be caught on the top wall 22 so that the bottle body can be easily grasped. Since the lower surface wall has a gently curved shape that is convex outward, it easily fits in the palm and can easily apply force when tilted. The degree of the steep inclination of the upper surface wall 22 is preferably an angle of 40 to 50 degrees with respect to the horizontal. When the length c of the lower surface wall 23 is 1.5 to 2.5 times the length a of the minimum diameter portion 21 and has a gently curved shape having a radius of curvature of 3 cm to 15 cm, it is particularly easy to adapt to the palm. preferable.
