Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine for crushing empty containers such as PET bottles.

[0002]

2. Description of the Related Art Conventionally, when an empty container such as a PET bottle is crushed by hand or foot, the empty container is placed on the upper surface of a flat base, and the lower end is pivotally mounted on the base so as to be vertically rotatable. The flat lower surface of the pressing plate was crushed.

[0003]

In the above prior art, when a crushed container such as a plastic bottle is returned to its original state, the container is slightly returned due to the elasticity of the container itself. However, there was a problem that the number was reduced by half.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and the surface of a base on which an empty container such as a PET bottle is placed is curved upward toward both sides from a central vertical portion. The lower surface of the pressing plate having a curved concave surface and the lower end pivotally attached to the base so as to be vertically rotatable is a curved convex surface that matches the curved concave surface, and a cap portion of the plastic bottle is fitted to the curved convex end.
It is characterized in that a cut-out portion for entering is formed .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the illustrated embodiments. Reference numeral 1 denotes a base on which empty containers such as PET bottles are placed, and the surface is formed from a central vertical portion 2a.
Both sides 2b are curved concave surfaces 2 curved upward, and the lower surface of a pressing plate 4 whose lower end is pivotally connected to a rotating shaft 3 at one end of the base 1 so as to be vertically rotatable. And At the tip of the curved convex surface 5, a notch 5a into which the cap of the plastic bottle fits is formed. A protruding piece 6 protrudes from the rear end of the central vertical portion of the curved concave surface 2, and display lines 7, 8 of 1.5 liters and 0.5 liters are displayed in front thereof. 9
Denotes a tip grip portion of the pressing plate 4.

Next, the operation will be described. The empty container of the PET bottle is placed on the curved concave surface 2 with the cap part first. In the case of a 2 liter container, the bottom contacts the protruding piece 6,
In the case of a 1.5 liter container, it is aligned with the display line 7, and in the case of a 0.5 liter container, it is aligned with the display line 8. Then, the distal end grip 9 of the pressing plate 4 is gripped and turned downward to crush the plastic bottle. At this time, the cap part which is harder than the container body and hard to crush is fitted into the notch 5a, and the plastic bottle is pressed by the curved concave surface 2 and the curved convex surface 5 and crushed in a curved state. Since the crushed plastic bottle is curved, the crushed plastic bottle maintains a curved flat state. Note that the tip grip 9 may be stepped on with a foot.

[0007]

According to the present invention, the surface of a base on which an empty container such as a PET bottle is placed is a curved concave surface which is curved upward toward both sides from the central vertical portion, and the lower end is freely rotatable about the base. The lower surface of the pressing plate pivotally attached to the curved convex surface conforms to the curved concave surface, and the tip of the curved convex surface has a cap of a plastic bottle.
Since the notch part into which the cap part fits is formed, an empty container such as a PET bottle is crushed in a curved state. And the volume of the crushed container can be made sufficiently small.
