Description

The present invention relates to a PET bottle compression device.

Conventional compression methods include crushing a plastic bottle with both hands or feet, placing it between foot pedals and crushing it, and recently, manually reciprocating a piston built in a cylinder to remove air inside the plastic bottle container. There is a manual pump type PET bottle compression device that sucks water.

The above-mentioned container compression device sucks air by manually reciprocating the piston in the cylinder from the nozzle at the tip of the cylinder with the air in the PET container, and prevents the air flowing into the cylinder chamber from flowing back to the PET bottle. A structure with a check valve is provided, and the air in the plastic bottle can be sucked in by repeatedly reciprocating the piston manually.

The method of manually sucking air and compressing the container as described above is well known as utilizing the reverse structure of the manual air filling of a bicycle.

However, there has been no idea that the plastic bottle can be crushed even more happily by using other powers without manually operating the power source of the piston.

Therefore, a more enjoyable method of compressing a PET bottle is to change the power for reciprocating the piston to manual, and to compress the PET bottle with a compression device having a mechanism using gripping force.

By the way, a container compression device for manually reciprocating a piston is currently commercially available (for example, see Patent Document 1).

There are various methods to compress and crush PET bottles, such as a crusher using a foot pedal, a pump crusher that sucks and crushes the air in the PET bottle manually, and crushing by stomping with feet with both hands without using equipment There is a way. However, compression and crushing of PET bottles for disposal as garbage is not widely used. The situation in which used PET bottles are collected as resource waste is that the probability of being compressed and crushed is low and the cost of transporting the waste as waste is extremely high, which is extremely cost-effective. Also, from a consumer's point of view, the number of PET bottles contained in the garbage bag is clearly inefficient compared to when the PET bottle is compressed and crushed.

Therefore, an object of the present invention is to improve the penetration rate of PET bottle crushing. For example, after drinking a carbonated beverage with high calories, the plastic bottle is crushed by its own grip strength, so that it will be penetrated by general consumers as health-oriented goods that strengthen grip strength and consume some calories. As a result, it contributes to the spread of compression and crushing of PET bottles.

The point of this invention is that the connecting slide frame that connects the palm frame, the gripping force operation frame and the return spring locking frame is formed in a substantially rectangular shape, and returns to the piston rod that is connected to the return spring locking frame of the connecting slide frame. A spring is interposed, the gripping force operation frame is retreated by the gripping force, the piston rod connected to the return spring retaining frame and the piston in the cylinder are retracted, and the air in the PET bottle is moved to the end of the cylinder. Suction is performed by the nozzle provided with the piston rod, and is discharged from the air discharge port at the base of the piston rod through the air discharge path in the piston rod, and the piston rod and the piston in the cylinder are advanced by the advance operation of the return spring. The air in the plastic bottle can be sucked and discharged by repeating the departure and advance operations.

Hereinafter, the effect of sucking 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. When the gripping force operation frame 1 in which the return spring 4 is locked is retracted by the gripping force, and the gripping force operation frame 1 comes closest to the palm frame 23, the return spring 4 is in a state of maximum extension and the load of the gripping force is exerted. Is maximized and sucks the air in the PET bottle to the maximum. Next, when the grip force of the grip force operation frame 1 is completely released, the return spring 4 starts to contract and the grip force operation frame 1 advances, and when the return spring 4 is minimized, the grip force operation frame 1 increases from the palm frame 23 to the maximum. Leave. The air in the plastic bottle is sucked by repeating this series of operations.
FIG. 1 shows a mechanism frame 6 formed in a grip shape of a PET bottle compression device 100 and a return spring 4 provided on a piston rod 12, a nozzle 7 for sucking air 9 from the PET bottle, and a sucked air. FIG. 5 is a front view of a cylinder 5 that performs a discharging process.

The substantially rectangular frame-shaped mechanism frame 6 is composed of a palm frame 23, a gripping operation frame 1, a return spring retaining frame 3, and a bottom frame 24. Both ends of the return spring 4 are connected to the return spring retaining 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 retaining frame 3 constituting the connecting frame 10, so that the piston 21, the piston rod 12, and the return spring retaining frame 3. The return spring 4 is interlocked with the retreating operation of the gripping operation frame 1. The air in 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 as the piston 21 advances and retreats.

FIG. 2 is a transparent front view when the piston rod 12 and the piston 21 connected to the gripping force operation frame 1 are retreated to the middle of the cylinder 5 by the gripping force.

By the retreat 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 portion A in the cylinder 5. At this time, the upper valve 13 and the lower valve 14 that constitute the piston 21 and the O-ring that is provided between the upper valve 13 and the lower valve 14 and that can move up and down Create a gap 13a. As a result, the air in the portion B in the cylinder 5 is discharged from the gap 13a through the air discharge path 22 of the piston rod 12 and from the air discharge port 20 of the piston rod base 2.

At this time, the retreating distance of the gripping force operation frame 1 by the gripping force is the return spring locking frame 3 and the piston rod 12, the piston 21 in the cylinder 5, which is interlocked with the coupling frame 10 sliding in the coupling frame slide groove 11, and the return. The retreat distance of the spring 4 is the same.

In addition, a restoring force acts on the return spring 4 so that the same load as the retreating operation of the gripping force operation frame 1 attempts 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 gripping force operation frame 1 by the gripping force are retreated to the top of the cylinder 5 by the gripping force.

At this time, the gripping force operation frame 1, the return spring locking frame 3, the piston 5 and the piston rod 12 are operated to retreat to the maximum, the retreat distance is also to the maximum, and the return spring is also retreated to the maximum (= extended). is there.

The nozzle 7 can be designed to suck the same amount of plastic bottle air as the capacity of the cylinder 5. For example, if the inner diameter of a cylindrical cylinder is 6 cm in radius and 3 cm in height, it will be 6 x 6 x 3.14 x 3 ≒ 340 ml, and when the gripping operation frame 1 is retreated by one gripping force, the plastic bottle 350 ml Air can be almost sucked. Therefore, suction can be completed by at most two to three retreat operations. In other words, the amount of air suction by one retreat operation can be freely changed by changing the inner size of the cylinder 5.

FIG. 4 shows that the return spring 4 is provided around the piston rod 12, one end of the return spring 4 is locked on the return spring locking frame 3, the other end is locked on the bottom frame 24, FIG. 7 is a transparent front view when the piston advances to the middle of the cylinder by the advance operation by the spring 4.

The connecting frame 10 advances by the restoring force of the return spring 4, slides in the connecting frame slide groove 11, and the piston 21 and the piston rod 12 also advance the same distance. The stronger the advance output (= restoring force) of the return spring 4, the faster the advance speed. Almost at the end of the advance, the advance output becomes weak and the advance speed decreases. Therefore, it is important that the return spring 4 be kept in a state where it has a restoring force even when it has advanced a maximum distance, that is, a state where some restoring force is left.

At this time, the air in the portion B of the cylinder 5 is prevented from flowing back into the plastic bottle by the check valve, and the O-ring of the piston 21 is brought into close contact with the upper valve 13 so that the lower valve 14 and the inner wall surface of the cylinder 5 contact each other. Create a gap 14a between them. As a result, the air in the portion B in the cylinder 5 is discharged from the gap 14a through the air discharge path 22 of the piston rod 12 and from the air discharge port 20 of the piston rod base 2.

FIG. 5 is a transparent front view when the gripping force according to the gripping force operation frame 1 is released and the return spring 4 operates to advance to the maximum.

At this time, the gripping force operation frame 1, the return spring locking frame 3, the piston rod 12, and the piston 21 are advanced to the maximum and the extension distance is the maximum, and the return spring 4 is in the state of being reduced to the minimum. The piston 21 has arrived at a check valve on the bottom surface of the cylinder 5. However, the return spring has not completely contracted, leaving a restoring force.

In this way, the gripping force operation frame 1 is retreated 8 by the gripping force, the piston 21 provided in the cylinder 5 is moved to the ceiling of the cylinder 5, and the same amount of air as the inner size of the cylinder 5 is passed through the nozzle 7 into the plastic bottle. Air 9 can be sucked. When the gripping force is released, the piston 21 at the ceiling position of the cylinder 5 advances to reach the bottom surface of the cylinder 5 by the restoring force of the return spring 4 to reach the bottom surface of the cylinder 5 and reach 17. By repeating a series of operations, the air 9 in the plastic bottle can be sucked and discharged. Further, even if the piston 21 is designed so as not to reach the ceiling and the bottom of the cylinder, the amount of air suction can be obtained by the radius of the inner dimension of the cylinder 5 × the radius × the vertical movement distance of the piston × pi.

FIG. 6 is a transparent front view of the fitting lid 18 that fits into the diameter of the PET bottle in place of the nozzle 7.

Usually, the diameter and shape of the mouth of the PET bottle are determined according to the JIS standard, so that a close fit can be created with a fitting lid that matches the shape of the screw of the PET bottle. Since the fitting lid is provided with a screw on the inner side that is in close contact with the diameter of the plastic bottle, the mouth of the plastic bottle can be inserted and rotated to fix the diameter of the plastic bottle in close contact.

Further, by making the nozzle portion a hose type, the angle at which air in the plastic bottle is sucked can be freely changed.

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

By changing the number of the return springs 4, the load when the gripping force operation frame 4 is retreated can be adjusted. For example, if the load of one return spring is 5 kilograms and the number is 4, the weight is 5 kilograms x 4 + suction power (power to suck air in the plastic bottle). Thus, the adjustment can be performed by changing the load or the number of the return springs 4 themselves.

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

A mechanism for sucking and discharging 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 that it can be displaced in the axial direction by a predetermined amount. The O-ring 15 is configured so as to be able to seal between one of the valves and to form a gap between the O-ring 15 and the other of the valves. As shown in FIG. 8, in the step in which the piston 21 moves away from the nozzle 7 by the gripping force, the O-ring 15 seals the space between the lower valve 14 on the side where the nozzle 7 is provided and the inner surface of the cylinder 5. Stop. Therefore, a negative pressure is generated in the cylinder 5 below the piston 21, the air check valve 16 is opened, and the air in the plastic bottle is sucked into the cylinder 5. A gap 13a is formed between the upper valve 13 and the cylinder inner surface. The air in the upper part B of the piston 21 flows 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 in which the piston 21 moves in the direction of the nozzle 7, the O-ring 15 seals the space 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 move. Is formed between them. At this time, since the air check valve 16 provided in the nozzle 7 prevents the backflow of air to the plastic bottle, the air in the cylinder 5 below the piston A between the lower valve 14 and the inner surface of the cylinder 5 The air is discharged to the gap 14a, the air discharge path 22, and the air discharge port 20.

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