い形状となる。In the plastic bottle of the present invention constructed as described above, the shoulder portion has a shape which facilitates the returning as a whole, thereby preventing dents and crushing. Specifically, since the first curved surface portion does not project outward from the side wall of the body portion and the diameters of the first curved surface portion and the second curved surface portion are continuously reduced, The shape is very easy to move from the force. This results in a shape that is resistant to permanent deformation against lateral force. In addition, since the flat peripheral surface portion that connects the upper end of the body portion and the first curved surface portion is provided, the shape is such that it is unlikely to be depressed and is not easily bent.

A plastic bottle 10 according to one embodiment of the present invention is shown. The plastic bottle 10 of this embodiment is
So-called P formed from polyethylene terephthalate resin
It is called an ET bottle, and has a neck portion 11 and a body portion 12.

The depth at c is about 2.5 mm, and in this case, the depth at both ends is preferably about 1 mm. It is also important that the central portions of the upper and lower ends 15a and 15b of the reduced pressure absorption panel portions 15 are evenly shallow so that they do not become deep along the curved surface of the body portion 12.

It has a shape that suppresses the rigidity at the upper and lower ends and limits it to the function of absorbing reduced pressure, so that it easily returns when dented.
Further, due to the shape of the shoulder portion 13, the force from above does not concentrate on a part and the rigidity from the side surface is minimized. Moreover, since the shoulder portion 13 is formed as a curved surface whose diameter is continuously reduced as a whole due to the connection of the two curved surface portions 17 and 18 having different center points and different radii as described above. , Lateral force makes it very easy to move. This results in a shape that is resistant to permanent deformation against lateral external force.
