[Technical field to which the invention belongs]

 The present invention belongs to the field of separating lids made of different materials from containers to be collected for recycling and containers attached to the container mouth.

[0002]

[Prior art]

 Caps that are plugged into PET bottles or glass containers suitable for recycling purposes are often made of polypropylene or polyethylene. Although it is necessary to separate the container and the sealing lid at the time of disposal for the purpose of recycling the container, the separation work has not been performed sufficiently. One of the reasons is that the cap fitted to the container with a stopper is tightly adhered, and it is difficult for individuals to separate them without using tools at the time of disposal. There are various proposals to solve this. Japanese Utility Model Application Laid-Open No. 57-174360 discloses that a "knob" is provided on the outer cylinder, and the bottle lid is detached from the outer cylinder wall by a slit groove oblique to the axis of the outer cylinder and a tear line parallel to the top surface. Is disclosed. The knob has a structure that protrudes outward from the outer cylinder of the bottle lid, and is easily caught, which is not convenient. Japanese Patent Application Laid-Open No. 9-58716 discloses a removable cap. In this case, a holding piece is provided outside the outer cylinder. Japanese Utility Model Laid-Open No. 4-118348 discloses that a thin portion is provided circumferentially and axially on a cap outer cylinder, a grip piece integrally formed at the intersection is pulled outward, and the thin portion is cut off to remove the cap. doing. In Japanese Utility Model Laid-Open No. 5-34151, a weakening line is provided in the hinge portion in the axial direction of the outer cylinder so that containers and lids can be separated without using tools even by individuals at the time of disposal. However, there was a drawback that the lid itself was easily damaged due to the effect of the weakening line during tapping.

[0003]

[Issues solved by the invention]

 A thin-walled part that is attached to the container to be collected for recycling purposes and the container mouth, and can easily separate a part of the outer cylinder at the individual level without the use of tools to separate the stopper cap made of different material from the container. The purpose is to develop a stopper cap that is not damaged during stoppering.

[0004]

[Means for Solving the Problems]

 As a result of diligent examination of the position and shape of the thin-walled part that serves as a guideline for separation in order to solve the above problems, the thin-walled part covers the outer cylinder from the top surface of both ends of the hinge connecting the outer cylinder and the lid to the outer cylinder lower end The present invention has been completed by finding one by one in the axial direction of the cylinder and by providing it on the top surface of the outer cylinder sandwiched between the inner cylinder and the outer cylinder from both ends thereof. That is, according to the present invention, the inner cylinder and the outer cylinder having the fitting protrusions toward the inner side are integrally molded with the lid, and the outer cylinder is provided with the thin portion, and the thin portion is the hinge portion. The upper surface of the outer cylinder sandwiched between the inner cylinder and the outer cylinder from both ends of the hinge is provided on the outer cylinder surface at both ends from the upper surface of the outer cylinder to the lower end in the batting lid axial direction and symmetrically from the center of the hinge. It is a cap stopper for separating containers, which is also provided in the above.

[0005]

[Embodiment of the invention]

 In the present invention, the thin portion is a parallel line which is symmetrical with respect to the center line of the hinge in the axial direction of the outer cylinder from the outer cylinder top surface to the lower end at the left and right ends of the hinge, which is the contact point between the outer cylinder and the lid, and It is provided on the top surface of the outer cylinder sandwiched between the inner cylinder and the outer cylinder from both ends of the cylinder. The thin portion may have a portion in which the line of the thin portion provided on the outer side and / or the inner side of the outer cylinder is not parallel between the upper end and the lower end of the fitting protrusion.

When the lid of the tapping lid for separating the container is opened, the lid is strongly pushed downward, and a force is applied to the hinge portion. As a result, the thin portion provided on the top surface of the outer cylinder is pushed out, and a cut is made along this thin portion, which extends to both ends of the hinge. Next, when further force is applied, a pair of parallel thin-walled parts along the axial direction of the outer cylinder are cut open. The cut of the thin part that reaches the lower end of the outer cylinder is completely cut by pressing the container and pulling the lid, and the lid and the hinge part are separated from the outer cylinder. Next, the outer and inner cylinders remaining in the container and their surroundings can be easily separated from the container by pinching the cuts in the thin portion with fingers.

When the tapping lid having the inner cylinder and the outer cylinder, which is the subject of the present application, is attached to the container by a tapping method, a fitting protrusion is provided inside the outer cylinder to fix the container and the tapping lid. There is. When the crests of the fitting protrusions provided on the inside of the outer cylinder are driven along the outer wall of the container at the time of stoppering, the outer cylinder temporarily has a larger apparent inner diameter. Therefore, the outer cylinder is easily damaged. In order to avoid this, it is possible to make the outer cylinder part less elastic and less likely to damage it by providing a thin portion inside the outer cylinder to give elasticity to the outer cylinder part. The cross section of the thin portion is preferably a triangular shape or a shape close to this. In this case, it is advisable to set the direction of the triangle so that the positions on the outer and inner surfaces of the outer cylinder are the bases of the triangle.

As shown in FIG. 4-1) -4), the thin-walled portion must have a pair of parallel lines at least at the upper and lower ends of the outer cylinder inside and / or outside the left and right ends of the hinge. .

As shown in FIG. 3, the shape of the thin portion line in the axial direction of the outer cylinder extends from the top surface of both ends of the hinge 9 to the lower end portion 14. The shape spreads from top to bottom or from bottom to top, whether it is a parallel line (Fig. 3-1) or a part of it is parallel line (Fig. 3-2) -5)). It may have a shape. Hinge The thin portion provided on the top surface of the outer cylinder sandwiched between the both ends by the inner cylinder and the outer cylinder may be inside or outside the top surface.

As shown in FIG. 5, by providing the thin portion inside and outside the outer cylinder, a cut is likely to occur between the inner thin portion and the outer thin portion during the sorting work, so that the separating work becomes easy.

[0011]

[Example 1] A polypropylene cap-type seal lid having an outer cylinder diameter of 30 mm and an outer cylinder length of 15 mm is attached to the outer cylinder top surface at the left and right ends of the outer cylinder to the lower end of the outer cylinder, which is a contact point between the outer cylinder and the lid. A parallel thin portion interval of 13 mm each in the direction, and a thin portion was also provided on the top surface of the outer cylinder sandwiched by the inner cylinder and the outer cylinder from both ends. The fitting convex raised thin portion was set inside the outer cylinder at an angle of 45 degrees. After preparing this seal lid and plugging it into a pet container, the lid was opened and weight was applied downward with the hinge as a fulcrum of the lever and cut along the thin portion. Finally, the pet container was held by hand, and the remaining parts of the stopper lid around the outer cylinder and the inner cylinder were manually removed. As a result, no damage to the seal lid was observed when plugging. This was the range in which the container user could use normal force to dissect from the child to the old.

[0012]

[Effect of the invention]

 A thin-walled part is provided in the outer cylinder to separate the container to be collected for recycling and the stopper that is made of a different material from the container. This made it possible to easily detach a part of the outer cylinder part, and to develop a stopper cap that will not be damaged during tapping.
