Description

[Detailed Description of the Invention] The present invention relates to a container sealing device with a liquid injection guide, which is applied to sealing the opening of a container such as a kerosene iron.

In this type of conventional container sealing device, a cylindrical cap is integrally fixed to an opening formed in the top plate of the container, and a crank cap with radial grooves or a threaded cap is attached to the cap via a backing. In addition to tightly fitting the cap, a duck's beak-shaped liquid injection guide was rotatably attached to the cap, and a sealing protector cap was fitted to the cap as necessary.

However, in the above-mentioned sealing device, the mouthpiece, cap, liquid injection guide, etc. that make up the device are each separate products, so machining these parts is time-consuming and costly, and there are a large number of parts. However, there were also drawbacks such as the fact that it took time and effort to assemble each part to the container opening.

The present invention has been made to solve the above-mentioned conventional drawbacks, and the cap part that seals the release of the container top plate and the outer cylinder part that is fitted around the outer periphery of the release can be separated. In addition, by integrating the liquid injection guide into the outer cylinder part, it is possible to integrally mold the cap part, outer cylinder part, and liquid injection guide, reducing the number of parts and cost. The purpose of the present invention is to provide a sealing device for a container that can be used in one-touch installation when leaving the country.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, a top plate 2 of a container body 1 made of a metal plate or the like is provided with a refill 3 for injecting and dispensing kerosene, cooking oil, etc. It has a structure that is directly formed using a part of 2.

That is, the leaver 3 is composed of a cylindrical portion 3a that is a part of the top plate 2 that protrudes outward, and an edge portion 3b that is formed by semi-curling the protruding opening edge of the cylindrical portion 3a outward.

Reference numeral 4 denotes a cap portion for sealing the departure from Japan, which is made of synthetic resin such as polyethylene.
A truncated conical cylindrical closing part 4b connected to the lower end periphery of the insertion side opening and closed in the inner cylinder part 4a; It has a flange part 4C that is engaged with the upper end surface of the sun 3, and the outer periphery of the flat end of the inner cylinder part 4a is engaged with the connecting corner part 3C between the top plate 2 and the sun separation cylinder part 3a. A protrusion 5 for cap fixing is formed, and a protrusion 6 for a seal that presses against the inner peripheral surface of the departure cylinder part 3a is integrally formed on the outer periphery of the inner cylinder part 4a, which is located approximately in the outer circumference. is formed.

Further, an outer cylinder part 7 made of synthetic resin such as polyethylene is fitted to the outer periphery of the above-mentioned departure 3, and this outer cylinder part 7
The upper end edge is integrally connected to the flange 4C of the cap portion 4, and the inner surface of the flange 4C side to which both are connected has the inner surface of the outer cylinder portion 7 as shown in FIGS. 2 and 3. A V-groove 8 for cutting is formed in a ring shape along the circumference, and this V-groove 8
At the same time as the outer cylinder part 7 is made to function as a seal by the groove.
and the collar portion 4C can be easily separated and separated.

A portion of a loop-shaped glue 9 is integrally fixed to the upper surface of the flange 4C, located inside the V-groove 8 for separation.

Furthermore, the outer cylindrical portion 7 has a length such that its lower edge contacts or is very close to the top plate 2, and the inner periphery of the lower edge engages with the semi-curled edge of the sun-separated edge portion 3b. A retaining protrusion 10 is formed to prevent the outer cylinder portion 7 from being removed freely or intentionally from the detachment 3, and at the same time, the cap portion 4 when not separated is removed from the detachment 3. It is designed to ensure that it is held securely.

Reference numeral 11 denotes a liquid injection guide in the shape of a duck's beak made of a synthetic resin material such as polyethylene, the base of which is integrally connected to the outer circumferential wall of the outer cylinder portion 7.

Further, the cap portion 4, the outer cylinder portion 7, the knob 9, the liquid injection guide 11, etc. are integrally molded from synthetic resin.

Therefore, after filling the container body 1 with liquid such as edible oil,
When sealing the leaver 3, press the top surface of the flange 4C with the inner cylinder 4a of the cap part 4 aligned with the inside of the can 3, and the inner cylinder 4a will close as shown in FIG. It is fitted into the cylindrical part 3a of the departure 3, and the protrusion 5 is connected to the connecting corner 3C of the departure 3.
The sealing protrusion 6 is brought into pressure contact with the inner circumferential surface of the cylindrical portion 3a.

At the same time, the outer cylindrical portion 7 connected to the flange 4C is fitted with the outer periphery of the departure 3, and its retaining protrusion 10 is engaged with the semi-curled edge of the edge 3b to completely seal the departure 3. I will do it.

At this time, even if the tip of a screwdriver etc. can be inserted into the extremely small gap between the lower edge of the outer cylinder part 7 and the top plate 2 and the cap part 4 including the outer cylinder part 7 can be removed from the departure part 3, the vicinity of the departure part 3 Since the top plate 2 and outer cylinder portion 7 of the container are damaged, it becomes clear at a glance that the cap of the container body 1 has been maliciously removed.

In addition, when opening the container body 1 normally, press the knob 9.
If it is strongly pulled in the direction of the arrow in FIG. As a result of being pulled, the inner cylindrical portion 4a also begins to detach from the detachment 3, and when the knob 9 is pulled until the thin wall portion forming the groove 8 is almost broken, the cap portion 4 is completely removed from the detachment 3. It will be removed.

At this time, the outer cylindrical portion 7 remains fitted onto the outer periphery of the departure 3.

In addition, when pouring liquid from the liquid injection guide 11 from which the cap portion 4 has been removed, if the entire container body 1 is tilted in the direction of the liquid injection guide 11, the liquid will pass through the liquid injection guide 11 from the liquid injection guide 11. It will be leaked.

After dispensing a predetermined amount of liquid, if the container 3 is to be sealed tightly, the inner cylinder portion 4a of the cap portion 4 separated from the outer cylinder portion 7 may be pushed into the can opening 3.

Note that the means for separating the cap portion 4 and the outer cylinder portion 7 are not limited to (1) forming the groove 8 in a ring shape, for example, a method in which perforations are formed in a ring shape, or (2) a method in which a groove and a perforation are formed. Of course, it is also good to use it in combination.

As described above, in the present invention, the cap part that seals the container and the outer cylinder part that is fitted around the outer periphery of the container can be separated, and the liquid injection guide is provided on the outside of the outer cylinder part. The integrated structure allows each of these parts to be integrally molded from synthetic resin material, which reduces the number of parts that make up the sealing device, making it easier to process and reducing costs. In addition to being easy to measure, it also has the advantage of being able to be assembled to a remote location with a single touch, and the separable portion of the cap and outer cylinder can also function as a seal.
