Description

The present invention relates to a plastic bottle compression device.

Conventional compression methods include crushing a plastic bottle with both hands or with a foot, putting it between foot pedals and crushing it, and recently, manually reciprocating a piston embedded in a cylinder, air in a plastic bottle container There is a manual pump type plastic bottle compression device that sucks

The container compression device manually reciprocates the air in the pet container from the nozzle at the tip of the cylinder by manual reciprocation of the piston in the cylinder to suck the air and prevent the air flowing into the cylinder chamber from flowing back to the pet bottle It is equipped with a structure provided with a check valve, and air in the plastic bottle can be sucked by repeating reciprocating motion of the piston manually.

A method of manually aspirating air and compressing the container as described above is well known as utilizing the reverse construction of a bicycle's manual air bag.

However, there has been no idea of using a piston power source manually instead of manually to squeeze the plastic bottle even more fun.

Therefore, in the method of compressing the plastic bottle more pleasantly, the power for reciprocating the piston can be changed to manual, and the plastic bottle can be compressed by a compression device provided with a mechanism using gripping power.

By the way, a container compression device for reciprocating the piston by the above-mentioned manual operation is currently commercially available (see, for example, Patent Document 1).

In order to compress and squeeze a PET bottle, there are various ways, such as a squeezer with a foot pedal, a pump squeezer with the air in the squeeze bottle smashed manually by squeezing air by hand, and so on There is a way. However, it is not very popular to compress and squeeze plastic bottles and take them out as trash. The situation in which used plastic bottles are recovered as recyclable waste has a low probability of being crushed and crushed, and the transportation cost as rubbish is very high, which is extremely cost-effective. Also, from the viewpoint of the consumer, the number of plastic bottles put in the trash bag is considerably less efficient than the number of bottles housed in the trash bag as compared to the case where the plastic bottles are compressed and crushed.

Then, the place made into the object of the present invention pays attention to improvement of the penetration rate of plastic bottle crushing. For example, after drinking a high-calorie carbonated beverage, by crushing the plastic bottle with its own grip, it is intended to instill in the general consumer as a health-oriented product that strengthens grip and consumes some calories. As a result, it contributes to the spread of compression and crushing of plastic bottles.

The point of the present invention is that the palm frame and the connecting slide frame connecting the grip operating frame and the return spring locking frame are formed in a substantially square shape, and return to the piston rod connected to the return spring locking frame of the connecting slide frame A spring is provided and the grip operating frame is operated to retract by gripping force, and the piston rod connected to the return spring locking frame and the piston in the cylinder are retracted to move the air in the plastic bottle to the tip of the cylinder. The air is drawn by the provided nozzle and discharged from the air discharge port of the piston rod base through the air discharge passage in the piston rod, and the piston in the piston rod and the cylinder is moved forward by the return operation of the return spring. The air inside the plastic bottle can be sucked and discharged by repeating this leaving and advancing operation.

Hereinafter, the effect of suctioning the air in the plastic bottle by a series of operations of each member of the plastic bottle compression device 100 will be described with reference to the drawings. The return spring 4 is fully extended when the grip force actuating frame 1 is moved closer to the palm frame 23 by the grip force, so that the return spring 4 is fully extended and the load of the grip force is exerted. Will maximize and aspirate the air in the plastic bottle as much as possible. Next, when the grip on the grip operating frame 1 is completely released, the return spring 4 starts to shrink and the grip operating frame 1 starts to be retracted, and when the return spring 4 is minimized, the grip operating frame 1 is maximized from the palm frame 23 Leave. This series of operations is repeated to suck the air in the plastic bottle.
FIG. 1 shows a mechanism frame 6 having a substantially rectangular frame shape formed in a grip shape of a plastic bottle compression device 100, a return spring 4 interposed on a piston rod 12, a nozzle 7 for suctioning air 9 from a plastic bottle, and suctioned air. It is a front view of cylinder 5 which carries out discharge processing.

The substantially square frame-like mechanism frame 6 is composed of the palm frame 23, the grip operating frame 1, the return spring locking frame 3, and the bottom frame 24. Both ends of the return spring 4 are the return spring locking frame 3 and the bottom Each is locked to the frame 24. The opposite end where the piston 21 is installed at the end of the piston rod 12 is fixed to the return spring locking frame 3 constituting the connection frame 10, so the piston 21, the piston rod 12, the return spring locking frame 3. The return spring 4 is interlocked with the retracting operation of the grip operating frame 1. The air of each chamber divided by the piston 21 in the cylinder 5 is discharged from the air discharge port 20 of the piston rod base 2 through the air discharge path 22 of the piston rod 12 by advancing and retracting the piston 21.

FIG. 2 is a transparent front view when the piston rod 12 and the piston 21 connected to the grip operating frame 1 are retracted halfway of the cylinder 5 by the grip.

By the retraction operation of the piston 21, the air 9 in the plastic bottle is sucked from the nozzle 7 through the check valve 16 to the A portion in the cylinder 5. At this time, the upper valve 13 and the lower valve 14 constituting the piston 21 and the O-ring provided in the middle thereof for vertical movement are in close contact with the lower valve 14 and between the upper valve 13 and the inner wall surface of the cylinder 5 Make a gap 13a. As a result, the air in the B portion in the cylinder 5 is discharged from the air discharge port 20 of the piston rod base 2 through the air discharge passage 22 of the piston rod 12 from the gap 13a.

At this time, the retracting operating distance of the grip operating frame 1 by the grip force is the return spring locking frame 3 and the piston rod 12 interlocked with the connecting frame 10 sliding the connecting frame slide groove 11, the piston 21 in the cylinder 5, and the return The leaving distance of the spring 4 is the same.

In addition, the return spring 4 exerts a restoring force that causes the same load as the retracting operation of the grip operating frame 1 to restore the reaction in the opposite direction.

FIG. 3 is a transparent front view when the piston rod 12 and the piston 21 connected to the grip operating frame 1 by grip are retracted to the top of the cylinder 5 by grip.

At this time, the grip operating frame 1, the return spring locking frame 3, the piston 5 and the piston rod 12 are fully retracted, the retraction distance is maximum, and the return spring is also maximally retracted (= extended). is there.

It can be designed to aspirate plastic bottle air from the nozzle 7 in an amount similar to the volume of the cylinder 5. For example, if the inner size of the cylinder is 6 cm in radius and 3 cm in height, 6 x 6 x 3. 14 x 3 ≒ 340 ml, and when the grip operating frame 1 is operated for withdrawal by one grip, 350 ml of plastic bottle Air can be almost sucked. Thus, the aspiration can be completed by at most two or three withdrawal operations. In other words, by changing the inner size of the cylinder 5, the suction amount of air by one leaving operation can be freely changed.

FIG. 4 shows that the return spring 4 is provided around the piston rod 12, one end of the return spring 4 locks to the return spring locking frame 3 and the other end locks to the bottom frame 24 and returns FIG. 10 is a transparent front view when the piston is advanced to the middle of the cylinder by the advancing operation by the spring 4;

The restoring force of the return spring 4 causes the connecting frame 10 to move forward and slide the connecting frame slide groove 11, and the piston 21 and the piston rod 12 also move forward by the same distance. The speed at which the return spring 4 advances is faster as the advancing output (= restoring force) of the return spring 4 is stronger. Almost, at the end of the advance, the power is weak, and the advance speed is slow. Therefore, it is important for the return spring 4 to have a restoring force even when the maximum distance is advanced, that is, to leave a certain restoring force.

At this time, the air in the B portion of the cylinder 5 prevents backflow to the plastic bottle by the check valve, and the O ring of the piston 21 comes in close contact with the upper valve 13 and the lower valve 14 and the inner wall surface of the cylinder 5 A gap 14a is created between them. As a result, the air in the B portion in the cylinder 5 is discharged from the air discharge port 20 of the piston rod base 2 through the air discharge passage 22 of the piston rod 12 from the gap 14 a.

FIG. 5 is a transparent front view when the grip force related to the grip force operating frame 1 is released and the return spring 4 is fully advanced.

At this time, the grip operating frame 1, the return spring locking frame 3, the piston rod 12 and the piston 21 are fully moved forward and the moved distance is also maximum, and the return spring 4 is in a state of being reduced to the minimum. The piston 21 arrives at the check valve on the bottom of the cylinder 5. However, the return spring is not completely shrunk with restoring force.

In this manner, the grip operating frame 1 is moved away by the grip force 8 to move the piston 21 provided in the cylinder 5 to the ceiling of the cylinder 5 and air of the same volume as the inner size of the cylinder 5 is passed through the nozzle 7 inside the plastic bottle Air can be sucked. When the grip is released, the restoring force of the return spring 4 causes the piston 21 at the ceiling position of the cylinder 5 to advance to the bottom of the cylinder 5 and reach 17. The air 9 of the plastic bottle can be sucked and discharged by repeating the series of operations. Further, even if the piston 21 is designed not to arrive at the ceiling and bottom of the cylinder, the amount of air suction can be obtained by radius of the inner dimension of the cylinder 5 × radius × vertical movement distance of the piston × pi.

FIG. 6 is a transparent front view of the fitting lid 18 which is replaced with the nozzle 7 and fitted to the aperture of the plastic bottle.

Since the diameter and shape of the mouth of the plastic bottle are normally determined by the JIS standard, a close contact state can be created with a fitting lid that matches the shape of the plastic bottle screw. Since the fitting lid is provided with a screw that is in close contact with the bore of the plastic bottle inside, the mouth of the plastic bottle can be inserted and rotated to closely fix the bore of the plastic bottle.

In addition, by making the part of the nozzle a hose type, it is possible to freely change the suction angle of air in the PET bottle.

FIG. 7 is a front view when the number of return springs is changed.

By changing the number of return springs 4, it is possible to adjust the load when retracting the grip operating frame 4. For example, if the load of one return spring is 5 kilograms and the number is four, then 5 kilograms × four plus suction power (force to suction the air in the plastic bottle). Thus, adjustment can be made by changing the load or the number of return springs 4 themselves.

Although the return spring 4 has been described as a pull spring, it can be replaced by a material or structure having a return function such as a leaf spring or rubber.

Further, the mechanism of suction and discharge of air in the reciprocating operation of the piston rod 12 will be described below.

As shown in FIG. 8, the O-ring 15 between the upper valve 13 and the lower valve 14 of the piston portion 21 is supported so as to be axially displaced by a predetermined amount. The O-ring 15 is configured to be able to seal between one valve and the other while forming a gap between it and the other valve. As shown in FIG. 8, in the process of moving the piston 21 in a direction away from the nozzle 7 by gripping force, the O-ring 15 seals between the lower valve 14 on the side provided with the nozzle 7 and the inner surface of the cylinder 5. Stop. As a result, a negative pressure is generated in the lower cylinder 5 of the piston 21, the air check valve 16 is opened, and the air in the plastic bottle is sucked into the cylinder 5. Further, a gap 13a is formed between the upper valve 13 and the inner surface of the cylinder. The air in the upper portion B of the piston 21 is made to flow to the gap 13a, the air discharge path 22, and the air discharge port 20 and is discharged.

On the other hand, as shown in FIG. 9, in the process of moving the piston 21 in the direction of the nozzle 7, the O ring 15 seals between the upper valve 13 and the inner surface of the cylinder 5 while the lower valve 14 and the inner surface of the cylinder 5 And a gap 14a is formed therebetween. At this time, air in the cylinder 5 of the lower portion A of the piston 21 is between the lower valve 14 and the inner surface of the cylinder 5 because the air check valve 16 provided in the nozzle 7 prevents backflow of air to the plastic bottle. The air is allowed to flow to the gap 14a, the air discharge path 22, and the air discharge port 20 and discharged.

Thus, the O-ring constitutes the effect of the air check valve.
