Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container lid comprising a combination of a cap body having an opening for pouring out contents and an upper lid covering the cap body. More specifically, the container lid can be easily detached from the container body after use for disposal. The present invention relates to a container lid capable of separately collecting each material.

[0002]

2. Description of the Related Art A cap (hereinafter, referred to as a pull cap), which is formed by a consumer pulling up a tab along a score at the time of use to form a pouring opening for contents, is generally fitted to a container mouth. It comprises a cap body and an upper lid formed so as to cover the pouring opening formed in the top plate portion of the cap body. This pull cap is fixed to the mouth of the container with the cap body, and the cap is opened and closed with the upper lid.
The cap body is required to be relatively rigid from the viewpoint of sealing the container and to be firmly fitted to the mouth of the container.

Many of these pull caps are firmly attached to the mouth of the container by filling the contents with stoppers, so that it is very difficult to remove the cap body from the mouth of the container. On the other hand, due to the recent problem of waste, it is necessary to recycle resources, and waste is separated and collected according to its material. In particular, it is desired that a glass container such as a bottle provided with a resin cap is discarded by removing the cap from the container body.

[0004]

However, in the above-described pull cap, the cap cannot be easily removed from the used capped container, and it is dangerous to break the cap with a blade or the like. And
After all, since it was discarded with the cap attached, there was a problem that it was not possible to comply with the request for separate disposal.

Therefore, an object of the present invention is to provide a cap which can be easily removed from a used container with a cap.

[0006]

According to the present invention, a top plate portion and a skirt portion hung from the top plate portion are provided, and the top plate portion has a central portion which serves as a pouring opening. A cap main body provided with an engagement projection for fitting with a cap portion, a top plate portion and a skirt portion hanging from the top plate portion, and an upper lid fitted to the cap main body so as to cover the top plate portion of the cap main body. The skirt portion of the cap body is provided with a tab at a lower end portion of an outer surface thereof, and a score continuously extending from a lower end portion of the tab and extending upward from a lower end portion of the skirt portion is provided continuously in the circumferential direction. The cap is characterized in that it is positioned above the engaging projections of, and the lower end of the upper lid skirt is fixed below the circumferential score of the cap body skirt, and is fixed. It is.

[0007]

In the present invention, by breaking the cap body along the score provided on the skirt,
Since the cap body including the engaging projections for fixing the cap to the container opening is destroyed, the cap can be easily removed from the container opening. Moreover, since the circumferential score is fixed so as to be covered by the upper lid skirt,
Even when the contents are hot-filled, the cap can be prevented from expanding due to heat, and the score part can be reinforced and the cap can be firmly locked to the container body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings. Regarding an example of the cap of the present invention, FIG. 1 is a side cross-sectional view of a main part when applied to a container mouth part, FIG. 2 is a side view and a XX view of the cap body, and FIG. 3 is a cap body. FIG. 4 is a side sectional view of FIG. 4, and FIG. 4 shows a side sectional view of the upper lid, respectively. 1 to 3, a cap of the present invention, generally designated by 1, is a cap body 3 that is fitted and fixed to a container mouth portion 2, and a cap body 3 that covers the cap body 3 when the cap is closed. It comprises an upper lid 4 fixed to the cap body 3.

The cap body 3 is composed of a top plate 5 and a skirt 6, and the inside of the side wall 7 for pouring is defined in the central portion of the top plate 5 so as to define a portion to be a pouring opening. Has a score of 8. As is clear from FIG. 3, the pull-up tab 9 is provided in the part divided by the score 8.
Is provided. Inside the skirt portion 6 of the cap body 3, it hangs down from the top plate portion, and together with the skirt portion, the container mouth portion 2
Is provided with an annular side wall 10, and an engagement protrusion 12 that engages with a bead 11 provided outside the container mouth 2 is provided inside the skirt. Further, on the inner surface of the top plate portion of the cap upper lid 4, there are provided annular projections 13 which are in close contact with the pouring side wall 7 and maintain the sealing property of the cap.

A score 14 extending from the lower end of the skirt portion is provided on the inner surface of the skirt portion 6 of the cap body 3. This score is based on the cutout 1 at the bottom of the skirt.
A rising score 14a that is formed continuously from 5 and extends upward to a position higher than the position of the engagement projection 11;
Following this, there is a circumferential score b that extends in the circumferential direction almost around the skirt and extends to above the notch 15 at the lower end of the skirt. A tab 16 is provided in the vicinity of the notch 15, and by pulling the tab 16, the score is broken from the notch portion, which serves as a clue for breaking the cap body. Ratchets 17a and 17b are provided on the lower portion of the skirt portion 6 of the cap body 3 and the container mouth portion 2 so that the cap body fitted in the container mouth portion 2 does not rotate.

1 and 4, the skirt portion 18 of the upper lid 4 is formed such that the lower end of the skirt portion 18 is located below the position of the circumferential score 14b when the lid is closed. It also covers 14b and protects the score part.

According to the cap of the present invention, when the consumer first uses the contents after purchasing the product, the pouring opening of the top plate of the cap body is formed by pulling up the tab, and the upper lid is closed after the use. And save. When the contents are gone and the container is to be discarded, the tabs provided below the cap body can be pulled up to break the score, so that the engaging projections that fix the cap body to the container mouth can also be destroyed. The cap can be easily and reliably removed from the container.

As long as the cap of the present invention has the above-mentioned structure of the present invention, the upper lid and the cap body as shown in the drawing are not integrated, and the cap can be opened and closed by screwing, or the upper lid and the cap can be opened. It can be used for any of the hinge caps whose main bodies are connected by a hinge. Also, the pouring opening is formed by the consumer pulling up the tab and breaking the score at the time of use, and the pouring opening is formed from the beginning and the opening is sealed with a seal member. It may be one. Further, the score provided on the cap body may be provided on the inner surface of the skirt portion as shown in the figure, or may be provided on the outer side of the skirt portion. The cap of the present invention can be molded by injection molding of synthetic resin or the like. The cap of the present invention can be applied to containers of any material, but is made of a material different from the cap due to the characteristics of the cap of the present invention, such as a glass container, a metal container or a material different from the cap. It can be suitably used for a synthetic resin container or the like.

[0014]

According to the present invention, by providing a score inside the cap body from the lower end of the cap body skirt, and destroying the cap body along this score after using the contents, the cap can be easily removed from the container body. It can be detached, and when it is disposed of, it can be sorted and discarded according to the material. Further, since the upper lid is formed so as to cover the skirt portion of the cap body, the score can be provided without reducing the strength of the cap.
