Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a synthetic resin inner lid attached to the mouth of a bottle, which achieves the purpose of preserving the contents of the bottle and preventing unauthorized opening at first, and after the bottle is emptied, The present invention relates to a synthetic resin inner lid stopper provided with a functional configuration for removing the inner lid stopper from the bottle mouth when discarded.

[0002]

2. Description of the Related Art Conventionally, a synthetic resin inner lid plug attached to a bottle mouth has been discarded while remaining in the bottle mouth even after the bottle has been used.

[0003] Even if there is an inner lid plug configured to be able to remove these, as shown in FIG. 3, a mounting portion 101 for attaching the inner lid plug to the bottle mouth portion 3 is provided. In order to cut and remove the fastening ring portion 102 fastened to the portion 3, a tension tab 118 for tearing a thin slit 114 formed in the fastening ring portion 102 was provided.

[0004]

In this conventional example, a tension
Bubble 118 has the effect of ensuring rip (cut)
However, in the crowned state, the tension tab 118 is
Exposed on the outer peripheral surface of the
Even bottles that have not yet been discarded or in good condition
Due to curiosity when handling mobile work, over-the-counter sales, etc.
It is pulled, the ring part 102 is removed and the inner lid plug is mistakenly
The problem of coming off frequently occurs.

[0005] The formation of the tension tab 118 in the ring-fastened portion 102 also has a disadvantage that the design is not good in appearance.

[0006] The present invention, which has been made in view of the circumstances, such as described above, it is an object of the present invention, parallel to the over-the-counter
There is no fear of accidentally removing the inner lid stopper when
Not to lose the aesthetic appearance, and to enhance the product value
An object of the present invention is to provide a synthetic resin inner lid stopper having a removal function that can be waited for.

[0007]

[MEANS FOR SOLVING THE PROBLEMS] To achieve the above object
The technical measures taken shall be the beads or threads that cover the canopy.
A mounting part provided with an outer cylinder having
An inner lid plug with a fastening part to attach the mounting part to the bottle mouth
The diameter of the ring is larger than that of the mounting part.
A step portion corresponding to the lower end surface of the canopy is formed at the top, and the step portion is formed.
, The arc slit hole communicating with the longitudinal thin slit was distracted to the fastening bead formed on clamping ring portion lower end by the intersection with the thin annular slit which is engraved on Shimewa inner peripheral surface is bored
And the summary .

[0008]

According to the above technical means, when arranging in a store or in a store
When the head is not sold, such as when selling heads, pickpockets
The hole is completely protected (concealed) at the lower end of the canopy.
To prevent removal from the bottle mouth of the mounting part due to
You. Then, when the contents are consumed and the inner lid stopper is removed from the bottle mouth, by inserting a tool such as a screwdriver into the slit hole and gouging, it intersects with the annular thin slit engraved on the inner peripheral surface of the fastening ring part, clamping ring portion is cut by a vertical thin slit which extends in the fastening bead formed on Shimewa portion lower end, by the cutting, will be also thin annular slit is cut, the mounting portion is Ru is the Remove from the bottle mouth .

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a synthetic resin inner lid plug having a removing function, and FIG. 2 shows a top view in partial cross section of the inner lid plug.

[0010] This inner lid plug is composed of a mounting portion 1 made of polypropylene or polyethylene and a ring-fastening portion 2. The mounting part 1 is an inner cylinder 4 to be mounted inside the bottle mouth part 3.
And an outer cylinder 5 attached to the outside of the bottle mouth 3, a discharge cylinder 6 for discharging the contents of the bottle, and a top plate 7 on which these are erected. Is formed with an extraction port 9 which is opened by pulling the tension ring 8.

A canopy 11 having a bead or screw 10 formed on the outer peripheral surface thereof is attached to the outer cylinder 5.

A seal lip 12 is formed at the upper end of the discharge cylinder 6 to make sealing contact with the top plate of the canopy 11.
The outer peripheral surface of the seal ring 13 erected on the top plate is sealed and joined.

The tightening portion 2 is formed integrally with the lower edge of the mounting portion 1, and an annular thin slit 14 is formed in the inner peripheral surface near the portion connected to the mounting portion so as to go around the inner circumference. A fastening bead 15 is protruded from the inner peripheral surface of the lower end.

In addition, a vertical thin slit 16 is formed in the inner peripheral surface of the fastening ring 2 so as to intersect at least one of the annular thin slits 14 and extend to the fastening bead 15.

The connecting portion between the mounting portion 1 and the collar portion 2 has a larger diameter on the outer peripheral surface of the ring portion 2 than on the outer peripheral surface of the outer cylinder 5 of the mounting portion 1.
The lower end surface of the canopy 11 corresponds to the top of the ring
Forming the that step portion 17.

The step portion 17 is a step in which the outer peripheral surface of the canopy 11 is flush with the outer peripheral surface of the fastening ring portion 2 when the canopy 11 is attached to the outer cylinder 5. In part 17,
A slit hole 18 communicating with the vertical thin slit 16 is formed. Needless to say, the slit hole 18 may be provided with a thin film that can be easily broken by inserting a device such as a screwdriver.

The synthetic resin inner lid stopper having the above-described removing function is provided when the canister 11 whose contents are used is discarded when the canopy 11 is detached from the mounting portion outer cylinder 5. A step 17 between the outer cylinder 5 and the ring ring 2 appears, exposing a slit hole 18 formed in the step 17 .

Then, by inserting a tool such as a screwdriver into the slit hole 18 and making it gouge, the vertically thin slit 16 formed on the inner peripheral surface of the ring part 2 communicating with the slit hole 18 is cut. With the cutting, the annular thin slit 14 intersecting with the cutting is also cut.

When the fastening ring 2 that has fastened the mounting portion 1 is cut, the mounting portion 1 mounted on the bottle opening 3 can be easily removed from the bottle opening 3.

[0020]

According to the present invention, the present invention is constructed as described above.
At the time of moving work such as when displaying on the head or at the store sales, use the cap
A slit hole that is protected (concealed) and not exposed to the outside
Easily cut the ring closure by digging with
It can be easily removed. Therefore, the cutting operation of the ring
It is a method that can be easily performed using equipment such as a driver.
The tension tab is exposed on the outer peripheral surface of the ring
Mobile work or when over-the-counter, such as when to display in the store head as in the conventional example
At the time of sale, the fastening part is mistakenly cut or the same
The ring is never cut off,
Of the design effect, such as when the tension tab is exposed
That will not invite you and increase the value of your products
It is.
