Abstract

(57) [Summary] (Modifications required) [Problem] To separate a stopper cap made of a different material from a container for the purpose of recycling, provide a thin-walled part that can easily cut off a part of the outer cylinder, and stopper the stopper. There is a need to develop a stopper that does not damage the stopper at times. In a stopper cap in which an inner cylinder and an outer cylinder having an inwardly protruding ridge are integrally molded with a lid and a thin wall portion is provided in the outer cylinder, the thin wall portion is made of a material other than the hinge portion. On the outer cylinder surface, from the center of the knob in the axis direction of the hitting lid to the top of the outer cylinder, to the top of the outer cylinder, symmetrically from the center, and also provided on the top of the outer cylinder sandwiched between the inner cylinder and the outer cylinder from the left and right ends of the knob Was.

Description

[Detailed description of the invention]

[0001]

[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 and the mouth of the container, and that can easily cut off a part of the outer cylinder at the individual level without using tools to separate the stopper from a different material from the container. It is to develop a stopper cap that is not damaged during tapping.

[0004]

[Means for Solving the Problems]

 As a result of intensive studies on the position and shape of the thin-walled portion that serves as a guideline for separation to solve the above problems, the outer cylinder and the inner cylinder having the fitting ridge are formed integrally with the lid, and In a stopper with a thin part provided on the cylinder, thin parts are provided on both sides of the knob of the outer cylinder having knobs on the outer surface of the outer cylinder other than the hinge part from the top to the lower end of the outer cylinder on the outer cylinder surface. , Provided in the axial direction of the stopper cap symmetrically from the center of the pinch, and also provided on the top of the knob outer cylinder sandwiched between the inner cylinder and the outer cylinder from both left and right ends of the knob top. A new tapping lid has been developed.

[0005]

[Embodiment of the invention]

 When holding the container by hand, pulling out the knob with the finger, and pulling it upward from the lower side of the container, as shown in Fig. 5, the lower end of the outer cylinder has a thin-walled section and a force is applied along the thin-walled section. A break occurs and reaches the top. Next, when further force is applied, a cut in the thin portion shown in the enlarged view of the portion C in FIG. 2 provided also on the upper surface of the outer cylinder sandwiched between the inner cylinder and the outer cylinder occurs, and the lid and the remaining outer cylinder are removed. It can be easily separated from the container by pulling with your fingertips.

As shown in FIGS. 3 to 5, the thin portion needs to be a pair of parallel lines inside and / or outside the outer cylinder at the left and right ends of the knob.

As shown in the enlarged view of the portion C in FIG. 2, the knob 13 is lightly welded to the outer cylinder with the thin film 15, but this can be easily separated from the outer cylinder by applying a normal force to the finger. I can do it.

As shown in FIG. 5, it is practical to provide a fingertip with a slip stopper 14 at the lower end of the knob.

[0009]

Example 1 A cap with a cap of a polypropylene type having an outer cylinder diameter of 30 mm and an outer cylinder length of 15 mm, a thin portion parallel to the axial direction of the outer cylinder from the lower end of the outer cylinder at the left and right ends of the knob to the top surface of the outer cylinder, and a gap of 13 mm. A thin portion was also provided on the top surface of the outer cylinder sandwiched between the inner cylinder and the outer cylinder from both ends of the knob. A thin-walled mating convex portion was provided at an angle of 45 degrees on the inner side of the outer cylinder. After preparing this lid and plugging it into a pet container, the knob was taken out and a force was applied upward to cut along the thin-walled portion. Finally, the pet container was held by hand, and the remaining part of the stopper cap around the outer cylinder and the inner cylinder was manually removed. This was within the range of the container user's ability to rip the old man from the child with normal force.

[0010]

[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.
