Abstract

PROBLEM TO BE SOLVED: To simply remove a pouring device from a mouth of a bottle. SOLUTION: A vertical tear-up line 22 crossing an annular protuberant part 3 to be engaged with an annular groove b of a mouth part a and an upper tear-up line 20 and a lower tear-up line 21 extending oppositely in the inner circumferential direction from both ends of the vertical tear-up line 22 are formed at the inner circumference of a fitting tube 2 to be fitted to the mouth part a of a bottle A. An incision 24 for forming a tab 23 at the lower part of the lower tear-up line 21 is provided at the lower end of the fitting tube 2. After the tab 23 is pulled in the circumferential direction, the lower tear-up line 21, the vertical tear-up line 22 and the upper tear-up line 20 are torn up successively, and a pouring device is removed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin injection tool mounted on the mouth of a liquid container such as a bottle.

[0002]

2. Description of the Related Art A bottle filled with a liquid such as soy sauce or vinegar is usually provided with an injecting tool with a cap made of a synthetic resin molded product.

[0003] There are two methods for mounting the injection tool, namely, a screw-in method and a press-fitting method. In the screw-in method, it takes time and effort to mount the injection tool. It has the feature that it is easy to attach.

[0004]

In a conventional injection device mounted by press fitting, an annular projection is formed on the inner periphery of a fitting cylinder fitted to the mouth of a bottle, and the annular projection is formed by the annular projection. The configuration is such that the injection tool is prevented from coming off by engaging with the annular groove provided on the outer periphery of the mouth, so that the attachment is extremely strong and cannot be easily removed.

Therefore, when collecting used empty bottles,
It was extremely difficult to separate and collect the empty bottle and the injection device.

[0006] It is an object of the present invention to provide an injection tool which can be easily removed from the mouth of a liquid container such as a bottle.

[0007]

In order to solve the above-mentioned problems, the present invention has a fitting tube fitted on the outer periphery of the mouth of a liquid container, and is formed on the inner periphery of the fitting tube. In the injection tool for a liquid container made of a synthetic resin in which the annular projection is engaged with an annular groove provided on the outer periphery of the mouth to prevent the fitting cylinder from coming off, on the inner periphery of the fitting cylinder, A vertical tear line that traverses the annular protrusion, and an upper tear line and a lower tear line that extend in opposite directions in the circumferential direction from both ends of the vertical tear line are formed. A configuration was provided in which a notch for forming a knob was provided below the end of the lower tear line.

[0008] With the above construction, the lower tear line, the vertical tear line, and the upper tear line are sequentially torn by holding the knob and pulling it in the circumferential direction.
The engagement range between the annular groove and the annular protrusion is shortened, and the injector can be easily removed from the mouth of the liquid container.

If the sum of the circumferential lengths of the upper tear line and the lower tear line is set to be at least half the circumferential length of the fitting cylinder, the injector can be removed simultaneously with the tearing.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a state in which the filling device 1 according to the present invention is attached to the mouth a of the bottle A, and FIG. 3 shows a sectional view of the filling device 1 in the attached state.

The injection tool 1 is made of a synthetic resin molded product. As shown in FIG. 3, the injection device 1 has a fitting tube 2 fitted into the mouth a of the bottle A, and an annular projection 3 is formed on the inner periphery of the fitting tube 2. The annular projection 3 is fitted into the mouth a
Is engaged with the annular groove b formed on the outer periphery of the mouth a, and the engagement holds the fitting cylinder 2 in the attached state.

A cap holding tube 4 is provided above the fitting tube 2. An injection cylinder 5 is formed inside the cap holding cylinder 4.

The injection cylinder 5 has an inner bottom 6, and a tear line 7 formed of an endless groove is provided in the inner bottom 6, and the inside of the tear line 7 is an opening lid 8. Opening lid 8
A ring 9 for picking is provided on the upper surface of the device, and when the ring 9 is pulled up, the tear line 7 is torn and the opening lid 8 is removed, and a spout 10 shown in FIG.

The cap 1 fitted to the cap holding cylinder 4
1 is connected to the fitting tube 2 via a thin hinge 12,
It can be opened and closed about the hinge 12. A tongue 13 for opening and closing operation is provided on a part of the outer periphery of the cap 11. An engagement projection 14 is formed at a lower portion of the inner periphery of the cap 11. The engaging lip 14 is the cap 11
Is closed, the cap 11 is engaged with the lower surface of the engaging projection 15 formed on the outer periphery of the cap holding cylinder 4, and the cap 11 is held in the closed state by the engagement.

A lock band 16 is provided around the outer periphery of the cap 11 held in a closed state. As shown in FIG. 2, the lock band 16 is connected to the fitting tube 2 via a plurality of tearable connecting pieces 17. The lock band 16 is formed with an engagement piece 18 vertically opposed to the tongue piece 13 of the cap 11. For this reason, the cap 11 cannot be opened until after the lock band 16 is removed, and it is possible to prevent the cap 11 from being unnecessarily opened at the stage of display at a store or the like.

FIG. 5I is a developed view of the fitting tube 2 and the cap holding tube 4 shown in FIG. On the inner periphery of the fitting tube 2, upper and lower cylindrical portions 2a, 2
b, an upper tear line 20 and a lower tear line 21 extending in the circumferential direction of the fitting cylinder 2 are provided so as to be displaced in the circumferential direction, and an annular projection is provided between opposing ends of the upper tear line 20 and the lower tear line 21. A vertical tear line 22 is formed across the part 3. The lower cylindrical portion 2b has a notch 2 formed below the end of the lower tear line 21 to form a knob 23.
4 are provided.

In forming the upper tear line 20, here, as shown in FIGS. 5 (I) and 5 (III), a meat stealer extending in the circumferential direction is formed on the inner periphery of the thick portion 2c on the upper part of the fitting cylinder 2. 25 is formed between the outer peripheral portion of the cap holding cylinder 4 and the thin thick portion 26.
And the thin thick portion 26 is used as the upper tear line 20.

Upper tear line 20 and lower tear line 21
Is set to be at least half of the circumferential length of the fitting cylinder 2.

The injection device 1 shown in the embodiment has the above-mentioned structure. When the liquid filled in the bottle A is injected, the lock band 16 is taken off, the cap 11 is opened, and then the ring 9 is pulled up and opened. An inlet 10 is formed by removing the lid 8, and the liquid inside flows out of the inlet 10 by an operation of tilting the bottle A.

When the bottle A becomes empty, the empty bottle A is separated from the injection tool 1 when the empty bottle A is collected. At the time of separation, the cap 11 is opened as shown by a chain line in FIG. 6, and the knob 23 is pinched and pulled in the circumferential direction of the fitting tube 2, and the lower tear line 21, the vertical tear line 22, and the upper tear line 20 are separated. To be sequentially torn.

FIG. 7 shows a state in which the tear lines 20, 21, and 22 are torn, and the engagement range between the annular protrusion 3 and the annular groove b becomes less than half the circumferential length. The injection tool 1 comes off from the mouth a, and the injection tool 1 can be easily separated.

[0022]

As described above, in the present invention, when the knob is pulled in the circumferential direction, the lower tear line, the vertical tear line, and the upper tear line are sequentially torn, and the fitting tube is developed. Since the engagement range between the annular protrusion formed on the inner periphery of the joint tube and the annular groove provided on the outer periphery of the mouth is shortened, the injector can be easily removed from the mouth,
Sorting work is extremely easy.
