Abstract

PROBLEM TO BE SOLVED: To effectively crush the total flat without changing the position of bottle by energizing the lower end of a pressing plate with a spring, holding the pressing plate in a mountain shape like, and forming a window hole being fitted with a PET(polyethylen terephthalate) bottle neck part on the base part of a turning plate in a time of pressing. SOLUTION: An empty PET bottle is mounted on a base stand 1, a neck part is engaged and stopped at an upper notch part 11a of an engaging plate 11. Next, when the turning plate 3 is pressed with a foot, the intermediate part of the PET bottle is pressed and crushed with a peak part of the mountain shape like pressing plate 4. When it is pressed further, the mountain shape like pressing plate 4 is made like a flat plate resisting to the elastic force of a spring 9, the upper faces of fore and rear parts of deformed PET bottle are pressed and the total is crushed flat. Therefore, because the intermediate part is crushed and deformed with protruding, the force is collected to protruding parts of the fore and rear parts and these can be crushed easily.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a device for crushing an empty plastic bottle.

[0002]

2. Description of the Related Art A conventional PET bottle foot crushing device is shown in FIG.
As shown in FIG. 6, the PET bottle 10 is placed sideways on the base 20, and the pressing plate 21 is pressed by the foot to crush the middle portion of the PET bottle, and then the PET bottle is placed vertically as shown in FIG. Instead, the pressing plate was pressed again with the foot so as to be flattened.

[0003]

The above-mentioned conventional technique has a problem that the workability is poor because a plastic bottle that has been crushed once is replaced and crushed again.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to fix an end plate of a base to an engaging plate for inserting and locking the neck part of a PET bottle, and one end of a rotating plate. Is pivotally attached to the shaft at one end of the base in a vertically rotatable manner, and the upper end of a pressing plate adapted to be vertically bent into a mountain shape is pivotally attached to the lower end of the rotating plate at the upper end of the rotating plate, The lower end of the pressing plate is urged toward the tip side by a spring to hold the pressing plate in a mountain shape, and a window hole into which the neck portion of the PET bottle can be fitted at the time of pressing is formed in the base of the rotating plate.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail based on an embodiment. Reference numeral 1 denotes a base, which is a pressing plate in which a base portion of a rotating plate 3 is pivotally attached to a shaft 2 at one end so that the rotating plate 3 can be vertically rotated, and the lower surface of the rotating plate 3 can be vertically bent into a mountain shape. The upper end of 4 is pivotally attached to the upper end of the rotating plate, the protruding pin 5 is provided in the lateral direction of the lower end of the pressing plate 4, and the protruding pin 5 is fitted into the long groove 7 formed in the side plate 6 of the rotating plate 3. The protruding pin 5 and the side plate 6 and the pin 8 at the upper end
A spring 9 is stretched on the and, and the pressing plate 4 is constantly pulled upward and held in a mountain shape. A locking plate 11 for locking the neck portion of the plastic bottle 10 is fixed near the shaft 2 of the base 1. A window hole 12 into which the neck portion of the plastic bottle 10 is fitted is formed in the rotating plate 3 so as to face the locking plate 11. In addition,
The locking plate may be arranged on the tip side of the base 1.

Next, the operation will be described. The empty plastic bottle 10 is placed on the base 1 as shown in FIG. 2, and the neck portion 10a is fitted and locked in the upper cutout portion 11a of the locking plate 11. Next, when the rotating plate 3 is pressed by the foot, the top of the mountain-shaped pressing plate 4 first presses the middle portion of the plastic bottle 10 to crush it as shown in FIG.
When further pressed, the mountain-shaped pressing plate 4 becomes a flat plate against the elastic force of the spring 9 and presses the front and rear upper surfaces of the deformed PET bottle as shown in FIG. Even if you press a flat plastic bottle with a flat plate, it will not crush easily.However, if the middle part is crushed and deforms protruding, the force concentrates on the front and rear protruding parts, so you can easily crush it. it can.

[0007]

According to the present invention, a locking plate for inserting and locking the neck portion of a PET bottle is fixed to the end of the base, and one end of the rotating plate is pivotally movable up and down on the shaft of the base one end. The lower end of the pressing plate is pivotally attached to the upper end of the rotating plate, and the lower end of the pressing plate is biased toward the tip side by a spring. The pressing plate is held in a mountain shape and a window hole is formed in the base of the rotating plate so that the neck of the PET bottle can be inserted when pressed.Therefore, when the PET bottle is placed on the base, the middle part remains in that state. And the whole can be crushed in order and flattened, and the PET bottle can be crushed efficiently.
