[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap, and more particularly to a cap made of a synthetic resin having a virgin seal function for indicating unused.

[0002]

[Prior art]

SUMMARY OF THE INVENTION As a simple cap fitted to the mouth and neck of a container body to close the top opening of the mouth and neck, for example, the upper end of the mouth and neck is closed from the upper edge of the peripheral wall fitted to the outer periphery of the mouth and neck of the container body. The top wall is extended, or a fitting tube portion fitted to the inner surface of the neck of the container body is vertically provided from the back surface of the top wall. In order to express that the contents are not used, these caps cover the entire cap, or cover the entire container including the cap, and shrink pack with a synthetic resin film.
However, shrink packs require a high raw material cost and require equipment for that purpose.

It is an object of the present invention to propose an excellent synthetic resin cap which can express unused contents without such special packaging and can be easily detached from a container. Is what you do.

[0004]

In order to solve the above-mentioned problems, the cap of the present invention has a locking ridge 4 provided around the upper end of the outer periphery and a flange 5 provided at a predetermined position below the ridge 4. A top wall 8 for closing a top opening of the mouth neck 6 from an upper edge of a peripheral wall 7 fitted to the outer periphery of the mouth neck 6 above the flange 5. A cap body 2 in which a locking ridge 9 provided at the lower end of the inner surface of the peripheral wall 7 is elastically engaged with the locking ridge 4 so as to be locked so as not to come out; Outer periphery and peripheral wall 7 of finger hook projection 11 protruding from the lower end
The inner surface is connected via a number of rod-shaped broken pieces 12 protruding from the outer periphery of the lower end edge, and the band-shaped body 3 surrounding the periphery of the cap main body 2 so that the finger hooking projection 11 cannot be pushed up.

[0005]

In the state shown in FIG. 1 or FIG. 5, the belt-like body 3 is in the way and the finger hook projection 11 cannot be pushed up, and if it is forcibly pushed up, the rod-shaped broken piece 12 will be broken. Therefore, it is not possible to push up the finger hooking projection 11 unless the broken piece 12 is broken to remove the band 3, and hence the cap body 2 cannot be removed from the mouth and neck 6.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

1 to 4 show one embodiment of the present invention, in which 1 indicates a cap. The cap 1 is an integrally molded product of a synthetic resin formed by a method such as injection molding, and is composed of a cap body 2 and a band 3. The cap 1 is provided with a locking ridge 4 at the upper end of the outer periphery.
It is used by being fitted to a container body 1 having a mouth and neck portion 6 having a flange 5 provided at a predetermined lower position.

The cap body 2 has a lower end face opening formed by extending a top wall 8 for closing the upper end opening of the mouth neck 6 from an upper edge of a peripheral wall 7 fitted to the outer periphery of the container mouth neck 6 above the flange 5. The locking ridge 4 which is formed in a cylindrical shape and is provided on the lower end edge of the inner surface of the peripheral wall 7 is elastically fitted over the lower surface of the locking ridge 4 on the outer periphery of the mouth and neck portion 6 and is fitted so as not to come out. Further, the outer surface of the seal cylinder portion 10 vertically suspended from the peripheral portion of the rear surface of the top wall 8 at a predetermined distance from the peripheral wall 7 is fitted in a liquid-tight manner to the inner surface of the container body neck 6. Further, a projection 11 for finger hook having a circular arc shape in a plan view is projected from a lower end edge of a front portion of an outer surface of the peripheral wall 7, and the projection 11 is configured to be substantially the same as or slightly protruded from the flange 5.

The belt-like body 3 has a belt-like shape in which the lower edge of the inner surface is integrally connected via a plurality of rod-shaped broken pieces 12 protruding from the outer peripheral lower end edge of the main body peripheral wall 7 and the outer periphery of the finger hooking projection 11. The projection 11 extends from the left end of the front surface, extends along the outer surface of the peripheral wall 7 from the side surface of the projection 11, and surrounds a portion reaching the base end of the left end of the projection 11. The band 3 is configured such that the front end of the finger hook projection 11 that is exposed by cutting and removing each broken piece 12 is pushed up to remove the main body 2 from the mouth and neck 6. Further, a protruding portion 3a having an upper side protruding upward from the base end portion is provided, so that the strip 3 can be easily broken.

FIGS. 5 to 8 show another embodiment of the present invention. In this embodiment, the upper edge of the band 3 is attached to the outer periphery of the main body peripheral wall 7 and the outer periphery of the finger hook 11 by a large number. They are integrally connected via rod-shaped broken pieces 12. In addition, this band 3
Is a rod-shaped broken piece at the lower edge of the peripheral wall 7 in the outer peripheral portion of the main body peripheral wall 7.
A hanging wall portion 3c extending from the outer peripheral edge of the horizontal wall portion 3b having an inner edge connected to the outer periphery of the flange 5 extends from the outer peripheral edge of the flange 5; The upper end is connected to the outer periphery of the flange 5 through a rod-shaped broken piece 12 and is composed of a hanging wall portion 3c hanging down on the outer periphery of the flange 5. Further, a vertical groove 13 is provided at a predetermined position in the front portion, and the strip 3 is removed. Unless the finger hook projection 11 is pushed up, it is not possible.

[0011]

As described above, the cap of the present invention is provided with a large number of rod-shaped broken pieces 12 protruding from the outer periphery of the finger hook projection 11 protruding from the lower end of the outer peripheral front of the cap body peripheral wall 7 and the outer periphery of the lower edge of the peripheral wall 7. And the inner surface is connected to the belt, and the band-like body 3 surrounding the periphery of the cap body 2 is provided so that the finger hook projection 11 cannot be pushed up. Therefore, the unused contents can be used without using the shrink pack as in the related art. Can be expressed, and when the cap is fitted and fixed to the mouth and neck of the container
In addition, it can be performed with almost no load on the fragment 12,
As a result, the broken pieces may be damaged when the cap is attached.
There is no. Further, since it can be formed by integral molding of a synthetic resin, it can be manufactured at low cost.
