[0004] However, since ribs extending in the vertical direction are not provided throughout the body, when the body is pressed from the front and back in the radial direction, the bent ends on both sides of the flat body become curved surfaces, and the flat body is curved. Some thickness remained between the opposing surfaces of the sections, and the bent ends on both sides did not extend linearly. For this reason, when the flat body is rounded, a larger pressing force is applied, and if the bent portions on both sides are not flattened, the problem that the rounding cannot be easily performed occurs.
There was a problem that crushing could not be easily and completely performed.
And in the case of soft synthetic resin or thin PET
In the case of a bottle, it can be easily rounded and crushed,
In the case of a PET bottle having a certain thickness or a thick hard synthetic resin, there is a problem that it is difficult to crush the PET bottle.

The present invention has the following effects because it is configured as described above. A vertical rib or a wavy rib is inclined at the center of the bottle's trunk wall, a V-shaped rib is arranged at the shoulder peripheral wall, and an inverted V-shaped rib is arranged at the lower trunk, and the peripheral wall is folded outward at the center of the left and right wall surfaces. Accordingly, the surface of the trunk peripheral wall can be formed as a thin flat trunk portion having a predetermined shape.
Next, since the flat body portion is folded, the bottle can be easily folded into a predetermined shape, and the capacity of the crushed bottle can be reduced. Since the shoulder is bent around the upper grooved horizontal rib as an axis, the bottom wall edge of the deformed bottom is locked to the upper grooved horizontal rib, and the deformed bottom is sandwiched between the upper end of the trunk and the curved surface of the lower part of the shoulder Since it can be maintained in a folded state and is not easily restored unless external force is applied, it can be discarded as a waste bottle as it is.
