Description

[Detailed Description of the Invention] [Object of the Invention] <Industrial field of application> The present invention relates to a sealing cap for a lid, and more particularly to a sealing for preventing opening of the lid screwed to the mouth of the container. Regarding the cap.

<Prior Art> Conventionally, for example, a lid screwed to a spout of a beer barrel or other container is sealed on the lid so as not to be unlawfully opened by an unauthorized third party. The cap is attached. Once such a cap is attached to the lid, the lid cannot be opened without breaking the cap, so that it is possible to reliably prevent unauthorized opening.

However, it is desirable that the cap can be easily attached to the lid and that the cap can be easily removed when the user finally removes the cap.

<Problems to be solved by the device> In view of the findings of the inventor, the main purpose of the present invention is to
By attaching the sealing cap to the lid screwed to the mouth of the container, it becomes impossible to remove the lid with the sealing cap attached, and when the user finally removes the cap. Another object of the present invention is to provide an improved sealing cap for the lid, which can be easily removed.

[Structure of the Invention] <Means for Solving the Problems> According to the present invention, such an object is an opening-type sealing cap mounted on a lid screwed to a mouth portion provided in a container. The cap includes a plurality of divided bodies hinged to each other, an irreversible latch means for integrally connecting the divided bodies so as to surround the lid body, and one of the divided bodies can be further divided. A strip-shaped portion that is detachably provided in one of the divided bodies so that the strip-shaped portion can be detached in a transverse direction, and a grip provided upright on the strip-shaped portion so that the strip-shaped portion can be grasped when the strip-shaped portion is separated from one of the divided bodies. It is achieved by providing a sealing cap for a lid characterized by having a part.

<Operation> As described above, by constructing the sealing cap by the plurality of divided bodies hinged to each other, the sealing cap can be easily attached to the lid of the container and can be cut in a direction transverse to one of the divided bodies. By providing the strip-shaped portion and vertically arranging the grip portion on the strip-shaped portion, when the user finally removes the cap, the divided body can be broken by pulling the grip portion to separate the strip-shaped portion, and the cap can be removed. Can be removed.

<Embodiment> Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a sealing cap according to the present invention. For example, a lid 2 is screwed onto the spout 1 of the beer barrel, and a sealing cap 3 formed by integrally molding a synthetic resin material is attached to the lid 2. The cap 3 is for preventing the lid body 2 from being illegally opened before the user finally opens the lid body 2.

Before the cap 3 is attached to the lid body 2, as shown in FIGS. 2 and 3, the cap 3 is divided into a pair of divided bodies 4a and 4b, which are formed by dividing a disc-shaped body by its diameter. A semicircular top plate portion 5, a skirt portion 6 provided so as to hang down from an arcuate peripheral edge of the top plate portion 5, and a skirt so as to face the top plate portion 4 substantially in parallel. It has an inward flange portion 7 provided at the free end of the portion 6. Further, one end of each of the divided bodies 4a and 4b in the diametrical direction is integrally coupled to each other via a pair of thin-walled hinges 8. Therefore, when the cap 3 is attached to the lid body 2, it is bent by the hinge 8 so that the divided surfaces of the two divided bodies 4a and 4b are aligned with each other.

The cap 3 is provided with irreversible latching means for connecting the two split bodies 4a, 4b to each other. The latch means is provided on the side opposite to the diametrical hinges 8 of the two divided bodies 4a and 4b, and extends from the skirt portion 6 in a direction projecting from the divided surface of the one divided body 4a. Tongue 9
And a housing 12 provided on the skirt portion 6 of the other divided body 4b, and the housing 12 is formed with a hole 11 having an insertion port 10 that opens on the same plane as the divided surface. A check claw 13 is formed at the tip of the tongue piece 9 in the extending direction thereof, and the tongue piece is inserted into the hole 11 through the insertion opening 10 as shown in FIG. An elastic engagement piece 14 that elastically engages the check claw 13 of No. 9 is formed so as to extend obliquely from the insertion port 10 into the hole 11.

In addition, the other divided body 4b is provided with the inward flange portion 7 through the skirt portion 6 from the top plate portion 5 in a direction orthogonal to the divided surface.
Up to, a pair of slits 15 which are parallel to each other are provided, and both slits 15 form a band-shaped portion 16. In these slits 15, a plurality of thin-walled bridging portions 17 for connecting the strip-shaped portion 16 and the side portions on both sides thereof to each other are provided at appropriate positions. The strip-shaped portion 16 is provided with a grip portion 18 integrally formed so as to stand upright above the top plate portion 5. The grip portion 18 has a so-called pull top ring shape, and the bridge portion 17 is cut by hanging the finger on the grip portion 18 and pulling the split body.
The divided body 4b can be broken by separating the strip-shaped portion 16 from the 4b.

When the cap 3 configured in this way is attached to the lid body 2 screwed to the spout 1, first, the two divided bodies 4a,
Either one of 4b is covered on the lid body 2 from the outside in the radial direction. Next, the hinge 8 is bent to align the divided surfaces of the two divided bodies 4a and 4b with each other, and the tongue piece 9 is inserted into the hole 11 of the housing 12. By elastically engaging the non-return claw 13 with the elastic engagement piece 14, the two divided bodies 4a and 4b are integrated as shown in FIG. 1 and attached to the lid body 2 as the cap 3. To be In this state, the top surface of the lid body 2 is covered by the top plate portion 5, the skirt portion 6 covers the peripheral edge portion of the lid body 2, and the lower surface of the peripheral edge portion of the lid body 2 is also covered by the inward flange portion 7. The peripheral portion of the lid body 2 cannot be directly touched and the lid body 2 cannot be opened. Further, even if the cap 3 is gripped and rotated, it only idles, and the lid 2
Can't open.

By the way, when the check claw 13 and the elastic engaging piece 14 are in the engaged state, the elastic engaging piece 14 is oriented so as to prevent the check claw 13 from coming off as shown in FIG. Is elastically engaged, the tongue piece 9 is reliably prevented from coming off. Therefore, after the check claw 13 and the elastic engagement piece 14 are engaged with each other, they cannot be removed.

At the time of opening, the divided body 4b can be broken by pulling the gripping portion 18 and cutting the bridging portion 17 as described above, so that the cap 3 can be easily divided and removed. .

In the present embodiment, the cap 3 is divided into two, but the cap 3 is not limited to two, and three or more divided bodies may be combined. Further, although the top plate 5 is formed so as to entirely cover the upper surface of the lid body 2, it may be formed so as to surround the peripheral portion of the lid body 2.

[Effects of the Invention] As described above, according to the present invention, since the sealing cap is composed of the divided members hinged to each other, the work of attaching to the lid of the container can be easily performed.
The strip can be further broken by the strip provided on one of the split parts of the cap, and the grip is provided upright on the strip to facilitate the work of separating the strip,
The user can easily perform the work of removing the cap to finally open the lid.
