Description

  The present invention relates to a structure of a cap ring cutter for cutting a cap ring of a plastic bottle.

  The importance of waste recycling issues has been pointed out to prevent environmental destruction. Among them, PET bottle recycling is important. In the PET bottle, the container is formed of PET, that is, polyethylene terephthalate, and the cap is formed of a plastic other than PET. When collecting for recycling, it is necessary to separate the empty container and the cap.

However, the cap itself is easily removed from the container at the time of recovery, but the cap ring often remains while fitted into the mouth of the container. It is difficult to remove the remaining cap ring with bare hands.
In order to solve this difficulty, Patent Document 1 below proposes a cutter 101 for cutting and separating a cap ring as shown in FIG. The cutter 101 is provided with a substantially L-shaped portion 105 at the tip of a rod-shaped grip portion 103, and a blade 107 is formed at the tip of the substantially L-shaped portion 105. The inner corner portion 109 of the substantially L-shaped portion 105 is pressed against the edge of the mouth portion 113 of the empty plastic bottle 111 (FIG. 3B), and is gripped like an insulator using the pressed portion 115 as a fulcrum. When the portion 103 is lifted, the tip blade 107 pushes the cap ring 117 and cuts it (FIG. 3C).

JP2003-237894

However, in the above-mentioned Patent Document 1, the fulcrum at the time of cutting is not stable and is displaced immediately. Therefore, it is difficult to obtain a sufficient force to push the cap ring. For this reason, there is a risk that it may become difficult for children and housewives to use because of insufficient power.
Also, since the cutting work must be performed with the pressed part as a fulcrum, the distance from the fulcrum, which is the edge of the mouth, to the blade is completely determined, so the blade is on a circular arc with a completely fixed radius. Therefore, it is difficult to fit the blade to the cap ring in PET bottle products that have slightly different mouth lengths or cap ring widths.
Further, in Reference 1, the main body of the plastic bottle 111 is held, and the plastic bottle 111 and the grip portion 103 are pushed and bent by the principle of the lever to be cut. However, the PET material such as the mineral water plastic bottle 111 is used. In the case of a thin one, the PET bottle 111 main body has no strength, so that it is difficult to perform a bending operation.

  In order to solve the above problems, this device easily obtains sufficient force to cut the cap ring, and caps the blade even for PET bottle products with slightly different mouth lengths and cap ring widths. An object of the present invention is to provide a cap ring cutter that can be easily fitted to a ring.

  In order to solve the above problems, the first device is a cutter for cutting and separating the cap ring remaining in the mouth portion of an empty plastic bottle, and a leg portion constituting the cutter in a pair; A pivot shaft that crosses the legs in an X shape and pivots to each other, a clamping part formed at the front ends of the legs, a gripping part formed at the rear ends of the legs, Corresponding to the straddle part that is provided on one side of the clamping part and straddles the female screw part formed in the mouth part, and the recess part of the mouth part that is provided at the tip of the straddle part and the cap ring is fitted to It is a cap ring cutter characterized by having the blade which has the shape to do.

  The second device is a cap ring cutter characterized in that a jaw portion having a groove for accommodating the blade is provided on the other of the both clamping portions.

  According to the cap ring cutter according to the first or second device, a pair of legs constituting the cutter, such as pliers, pliers, or scissors, and the legs intersect each other in an X shape. Since it has a pivot shaft to be pivoted, a clamping portion formed at the tip of the both leg portions, and a grip portion formed at the rear end of the both leg portions, a sufficiently large force with the pivot shaft as a fulcrum Can be obtained.

For this reason, it is not necessary to perform the cutting operation with the portion pressed against the plastic bottle as a fulcrum as in Patent Document 1 described above. Therefore, even a weak person such as a child or a housewife can easily obtain a sufficient force for cutting the cap ring.
Moreover, since there is no need to perform cutting work with the pressed portion as a fulcrum as in the above-mentioned Patent Document 1, the blade can be moved to some extent freely with respect to the mouth of the plastic bottle. Therefore, it is easy to fit the blade to the cap ring even if it is a PET bottle product with slightly different mouth lengths and cap ring widths. In addition, it is not affected by the strength of the plastic bottle body.

Furthermore, since the blade is provided at the tip of the straddling portion straddling the female screw portion formed in the mouth portion, it is not necessary to contact the male screw portion of the mouth portion, and the cutting operation can be performed with a small force.
Further, since the blade has a shape corresponding to the concave portion of the mouth portion into which the cap ring is fitted, only the cap ring can be cut, and the cutting operation can be performed with a small force.
Furthermore, according to the cap ring cutter according to the second device, since the jaw portion having a groove for storing the blade is provided on the other of the both clamping portions, the blade is protected when the cap ring cutter is not used. You can also keep your hands and other things safe.

A cap ring cutter according to an embodiment of the present invention is shown in FIG.
As shown in FIG. 1A, the cap ring cutter 1 cuts and separates the cap ring 7 remaining in the mouth portion 5 of the empty plastic bottle 3, and separates the plastic bottle 3 and the cap ring 7 separately. It is for recovery.
In general, the mouth portion 5 of the plastic bottle 3 is cylindrical, and a male screw portion 11 corresponding to a female screw portion formed on the inner periphery of the cap is formed on the outer peripheral surface 9 thereof. A cap ring 7 is provided below the male screw portion 11, that is, on the left side in FIG. As shown in FIG. 1B, the cap ring 7 is fitted in the ring-shaped recess 13. The inner peripheral surface 15 of the mouth part 5 is flat.

In this embodiment, a plier 17 which is a conventional tool is used, and a blade 19 or the like is provided at the tip thereof to form the cap ring cutter 1.
That is, the pair of leg portions 21 constitutes a cutter. The leg portion 21 is crossed in an X shape, and a rotating shaft 23 is provided at the crossing portion. The pair of leg portions 21 are rotated by the rotation shaft 23. A pinching portion 25 is formed at the tip of both legs, and a gripping portion 27 is formed at the rear.

  A straddling portion 31 is formed on one of the both pressing portions 25, that is, the upper pressing portion 25 in the drawing, and straddles the male screw portion 11 formed in the mouth portion 5. The plate 33 is fixed to the front end of the straddling portion 31 by a rivet 37 provided in the hole 35. A blade 19 is provided on the plate 33.

As shown in FIG. 1B, the blade 19 has a substantially downward trapezoidal shape slightly larger than the recess 13 corresponding to the cross-sectional shape of the recess 13 into which the cap ring 7 is fitted. That is, it is larger than the recess 13 by +0.0 to 0.5 mm.
Of the blade 19, the cutting edge portion 39 that actually cuts extends not only the substantially U-shaped portion that continues the lower side, the left side, and the right side of the substantially downward trapezoidal shape, but also the left and right ends of the substantially U shape. It is formed up to a part and has an inverted Ω shape as a whole.

A jaw 43 having a groove 41 for accommodating the blade 19 is provided in the other of the two clamping parts 25, that is, the lower clamping part 25 in the drawing. The jaw 43 is longer than the blade 19 to prevent injury by the blade 19. Further, the jaw 43 is subjected to R processing in accordance with the inner peripheral surface 15 of the mouth 5.
Further, a hooking claw 45 having a reduced thickness is formed at the rear end of the leg 21, and is used when the cut cap ring 7 is easily removed from the recess 13.

[Cutting work]
The operation of cutting the cap ring 7 remaining in the mouth portion 5 of the empty plastic bottle 3 with the cap ring cutter 1 is performed as follows.
First, of the both clamping parts 25 of the cap ring cutter 1, the lower clamping part 25 in the figure where the jaw part 43 is provided is inserted into the mouth part 5 of the plastic bottle 3. Then, the upper clamping portion 25 in the drawing in which the blade 19 is provided is positioned outside the mouth portion 5 of the plastic bottle 3, and the blade 19 is positioned on the cap ring 7.

  Then, when both the gripping portions 27 are gripped and the cap ring 7 is clamped by the both clamping portions 25, the blade 19 of the clamping portion 25 cuts the cap ring 7. At this time, if the blade 19 is aimed so as to be fitted into the recess 13 into which the cap ring 7 is fitted, the cap ring 7 is not left uncut and complete cutting can be easily performed.

  If the hooking claw 45 formed at the rear end of the leg portion 21 is inserted between the cut cap ring 7 and the recessed portion 13 after the cutting, the cap ring 7 can be easily removed from the recessed portion 13.

[Effect of the embodiment]
According to the cap ring cutter 1 concerning the above embodiment, the following effects are acquired.
(1) That is, the cap ring cutter 1 is configured such that, as a pair of pliers 17, pliers, scissors or the like, a pair of legs 21 constituting the cutter are made to intersect with each other in an X shape to rotate each other. A sufficiently large force can be obtained with 23 as a fulcrum. For this reason, it is not necessary to perform the cutting operation with the portion pressed against the plastic bottle 3 as a fulcrum as in the above-mentioned Patent Document 1. Therefore, even a weak person such as a child or a housewife can easily obtain a sufficient force for cutting the cap ring 7.

(2) Moreover, since there is no need to perform cutting work with the pressed portion as a fulcrum as in Patent Document 1, the blade 19 is attached to the mouth portion 5 of the plastic bottle 3. Can move freely to some extent. Therefore, even if it is a PET bottle product in which the length of the mouth portion 5 and the width of the cap ring 7 are slightly different, it is easy to aim the blade 19 at the cap ring 7.

(3) Further, since the blade 19 is provided at the tip of the straddling portion 31 straddling the female screw portion formed in the mouth portion 5, the blade 19 does not need to contact the female screw portion of the mouth portion 5, and is small. Cutting work can be done with force.
(4) Moreover, since the blade 19 has a shape corresponding to the concave portion 13 of the mouth portion 5 into which the cap ring 7 is fitted, only the cap ring 7 can be cut, and the cutting operation can be performed with a small force.
(5) Further, since the jaw part 43 having the groove 41 for accommodating the blade 19 is provided on the other side of the both clamping parts 25, the blade 19 is protected when the cap ring cutter 1 is not used. You can keep it safe without damaging it or anything else.
(6) After the cutting, if the hooking claw 45 formed at the rear end of the leg portion 21 is inserted between the cut cap ring 7 and the recessed portion 13, the cap ring 7 can be easily removed from the recessed portion 13. .

"Other embodiments"
In the above embodiment, the plier 17 which is a tool that has existed in the past is used as the cap ring cutter 1, but in other embodiments, it is of course possible to use pliers or scissors.

In the above embodiment, the positioning of the blade 19 at the start of cutting is visually performed, so in another embodiment, for example, as shown in FIG. 2, a plate 33 on which the blade 19 is provided is devised. The blade 19 can be positioned by abutting the plate 33 against the mouth 5.
That is, the rear side of the plate 33 is extended and bent toward the mouth 5 in an L shape. The length of the insertion portion 52 of the L-shaped portion 47 so that the blade 19 is positioned on the cap ring 7 with the bent portion 49 of the L-shaped portion 47 abutting against the edge 51 of the mouth portion 5. Is set, the blade 19 can be positioned accurately and easily without visual inspection.

Further, if the length of the bent portion 49 of the L-shaped portion 47 is reduced, the insertion portion 52 is moved toward the mouth portion 5 together with the bent portion 49 without causing the butting portion 53 to function. It is possible to match the blade 19 with the cap ring 7 even in a plastic bottle product in which the length of 5 and the width of the cap ring 7 are slightly different. In the above embodiment, the blade 19 is fitted with the cap ring 7. Corresponding to the cross-sectional shape of the recess 13, the trapezoidal shape has a substantially downward trapezoid slightly larger than the recess 13, but in other embodiments, the shape of the blade 19 can be obtained by sufficiently sharpening the cutting edge 39. You don't have to worry too much about it. That is, if a deep cut can be made in the cap ring 7, the cap ring 7 can be removed by a hooking claw 45 described later.
In the above embodiment, the blade 19 is provided separately from the leg portion 21, but in other embodiments, for example, as shown in FIG. In this case, one of the two clamping parts 25, that is, the upper clamping part 25 in the drawing, gradually decreases in thickness at the tip of the straddling part 31 and eventually becomes the thinnest and sharpest at the blade 19 part.
