Description

The present invention relates to an adhesive container that opens a nozzle portion of a sealed container by twisting off a sealing tip at a tip of the nozzle portion.

2. Description of the Related Art A liquid or jelly-like adhesive made of a chemical substance solidifies when exposed to the outside air and becomes unusable. Therefore, it is necessary to store the adhesive in a completely sealed container.

Therefore, in the case of adhesive containers that are used in small batches, especially for highly volatile adhesives, the tip of the nozzle is completely sealed when not in use, and is opened at the start of use. Is usually taken.

Conventionally, the opening operation of the nozzle unit of this type has been performed by piercing the tip of the nozzle unit using an opening needle that is paired with the container.

According to the related art, when the tip of the nozzle is opened using a needle for opening, a finger of a hand is pierced by the needle, or the inside of the container is adhered from the opened nozzle. There was a danger that the drug would jump out and get into your eyes.

In addition, when using the adhesive divided, store it with the needle pierced in the nozzle, but this is incompletely resealed, so the remaining adhesive will be removed in a short period of time. It is not uncommon for it to solidify.

Therefore, the purpose of the present invention is to take the problem of the prior art into consideration and integrate the inner cap and the outer cap via a sealing tip at the tip of the nozzle portion of the inner cap, and to form a liquid stopping portion on the inner peripheral surface at the tip of the outer cap. By forming, it can be easily opened without the risk of the adhesive squirting out,
Moreover, it is an object of the present invention to provide an adhesive container that can easily perform a substantially complete resealing operation.

Means for Solving the Problems The configuration of the present invention for achieving such an object includes a container body, an inner cap screwed to an opening of the container body,
An outer cap screw-coupled to the inner cap, the inner cap has a tapered nozzle portion, and a sealing tip for sealing the nozzle portion via a thin portion, and the outer cap is provided via the sealing tip. The gist of the present invention is to integrate the inner cap with the inner cap and to have a liquid stopping portion formed of a ridge on the inner peripheral surface.

The container body can have a bellows structure at the bottom and a cover on the outer periphery.

According to the configuration of the present invention, since the nozzle portion of the inner cap is sealed by the sealing chip, the adhesive in the container is completely shut off from the outside air by attaching the inner cap to the container body. And can be saved.

At the start of use, when the outer cap, which is integrated with the inner cap via the sealing tip, is rotated so as to be detached from the inner cap, the outer cap opens the nozzle part by twisting off the sealing tip from the thin part. Can be done. Then, if the container body is pressed after the outer cap is removed from the inner cap, the adhesive can be pushed out from the opened nozzle portion.

In addition, since the outer cap and the inner cap are screwed together, after use, the outer cap can be re-mounted on the inner cap by rotating, and at this time, the ridges on the inner peripheral surface of the outer cap are used. The liquid stopping portion made of is in close contact with the outer peripheral surface of the tip portion of the nozzle portion of the inner cap, so that the container can be easily resealed.

When the bottom of the container body has a bellows structure, since the bottom is elastic, the adhesive can be easily extruded from the nozzle portion little by little by pushing up the bottom of the container body.

Embodiments Hereinafter, embodiments will be described with reference to the drawings.

The adhesive container has a container body 11, an inner cap 20, a cover
31 and an outer cap 41 (FIG. 1).

The container body 11 is a substantially cylindrical container made of a synthetic resin having appropriate flexibility such as low-density polyethylene. The container body 11 has a male screw 11a formed on the outer peripheral surface of the mouth 11f, and an annular central projection 1 below the male screw 11a.
1d, and has an annular small projection 11e below it. The bottom 11b has a bellows structure, and has a plurality of ridges 11c, 11c,.

The inner cap 20 has a tapered nozzle 22 formed above a base 21. On the inner peripheral surface of the base 21, a female screw 21a that fits the male screw 11a of the container body 11 is formed, and on the outer peripheral surface of the base 21, a knurl 21b is provided. A male screw 22a is formed on the outer peripheral surface of the lower part of the nozzle part 22, and a sealing tip 23 is formed at the tip of the nozzle part 22 via a thin part 22b.

The cover 31 is formed in a cylindrical shape having upper and lower end surfaces opened. A folded back 31b is formed on the lower end surface of the cover 31, and a circular opening from which the bottom 11b of the container body 11 projects is formed. A shallow annular concave portion 31c is provided at the upper portion of the inner peripheral surface of the cover 31 to engage with the small annular protrusion 11e of the container body 11, while a plurality of inner peripheral surfaces below the annular concave portion 31c are provided in the direction of the axis C. Are formed. FIG. 1, FIG.
Figure). The grooves 31a, 31a...
1c... In the direction of the axis C, and the grooves 31a, 31a
.., And the ridges 11c, 11c,.

The outer cap 41 can be fitted to the nozzle portion 22 of the inner cap 20 from the outside. The outer cap 41 has a female screw 41a on the lower inner peripheral surface that matches the male screw 22a of the nozzle portion 22, and has a liquid stopper 41b formed of a ridge that gently rises up in an annular shape on the inner peripheral surface of the tip. In addition, outer cap 4
The front end of 1 is integrated with the inner cap 20 via the sealing tip 23 of the nozzle section 22.

That is, in the manufacturing process, the inner cap 20 and the outer cap 41 are inserted into the outer cap 41 by screwing the inner cap 20 into the outer cap 41, and the sealing tip 23 of the inner cap 20 is opened at the tip of the outer cap 41. The sealing chip 23 is integrated by thermally deforming the sealing chip 23. However, the opening 41e at the tip of the outer cap 41 is
A plurality of projections 41d, 41d,... Are formed on the inclined surface 41c that expands upward (FIG. 4), and a circular insertion hole through which the sealing chip 23 is inserted is formed at the center.

A knurl 41f is provided on the outer peripheral surface of the outer cap 41 (FIGS. 1 and 4).

When starting to use the adhesive, the base 2 of the inner cap 20 is grasped with fingers, and the outer cap 41 is rotated. At this time, the outer cap 41 is screwed to the inner cap 20 and the sealing is performed. It is integrated with the inner cap 20 via the stopper tip 23. Therefore, the sealing chip 23 is
When the outer cap 41 is screwed in a direction in which the outer cap 41 is disengaged along the axis C, the thin portion 22b is separated from the inner cap 20 so as to be twisted, and the outer cap 41 is removed and the nozzle The tip of 22 can be opened (FIGS. 1 and 5).

After the outer cap 41 is removed from the inner cap 20, the tip of the nozzle portion 22 is brought into contact with the object to be bonded, the cover 31 is gripped, and a push operation is performed to push up the bottom of the container body 11.
The cover 31 and the container body 11 are positioned in the direction of the axis C by the engagement between the annular concave portion 31c of the cover 31 and the small protrusion 11e of the container body 11, and the bottom 11b of the container body 11 has a bellows structure. Therefore, the bottom portion 11b can be expanded and contracted in small increments in the direction of the axis C (solid line and two-dot chain line in FIG. 6), so that the adhesive can be extruded little by little from the nozzle portion 22 and used.

After using the adhesive, the outer cap 41 is reattached to the inner cap 20. Since the inner cap 20 and the outer cap 41 are screw-connected via the male screw 22a of the inner cap 20 and the female screw 41a of the outer cap 41, the outer cap 41 can be strongly adhered to the inner cap 20, and Since the liquid stopping portion 41b on the inner peripheral surface of the distal end portion of the outer cap 41 comes into close contact with the outer peripheral surface of the distal end portion slightly below the distal end of the nozzle portion 22 (FIG. 1),
The nozzle portion 22 can be completely resealed.

The cover 31 is positioned in the circumferential direction with respect to the container body 11 by engaging the grooves 31a, 31a... On the inner circumferential surface thereof with the ridges 11c, 11c. I have.
Therefore, after filling the container body 11 with adhesive, the inner cap
When screwing the inner cap 20 to the container body 11, the inner cap 20 is rotated by rotating the inner cap 20 while fixing the cover 31.
20 can be easily tightened. The same is true when the inner cap 20 is loosened during use.

In the above description, the liquid fixing portion 41b of the outer cap 41
May have any shape as long as it is in close contact with the outer peripheral surface of the tip of the nozzle portion 22. For example, if the radius of curvature of the cross section is reduced to approximate a semicircle (FIG. 7), even when the outer cap 41 is loosely tightened with respect to the inner cap 20, the liquid stopping portion 41 is formed.
b is sufficiently close to the outer peripheral surface of the nozzle portion 22, and the nozzle portion 22 can be resealed more reliably.

The opening 41e of the outer cap 41 may be provided with a square insertion hole at the center of the dish-shaped inclined surface 41c (FIG. 8). At this time, since the sealing chip 23 fills the gap between the openings 41e by thermal deformation, the inner cap 20 and the outer cap 41 can be more reliably integrated. In addition, since the structure of the outer cap 41 itself is simple, a mold for forming the outer cap 41 can also have a simple shape.

Note that the cover 31 and the container body 11 are configured such that, instead of engaging the small protrusion 11e on the container body 11 side and the annular recess 31c on the cover 31 side, the annular recess 11g on the container body 11 side and the annular protrusion on the cover 31 side. The positioning in the direction of the axis C may be performed by engaging the portion 31d (FIG. 9).

The cover 31 extends upward and substantially until it substantially contacts the lower end of the inner cap 20 (see FIG. 3), while forming a skirt portion 31e at the lower end and covering the bottom surface of the container body 11 to form a thin portion. A pressing portion 31g can be formed via 31f. Since the cover 31 covers the entire surface of the container body 11, sufficient light-shielding properties can be realized, and the cover 31 can be particularly suitably applied to an adhesive that is deteriorated by light. In addition, the skirt portion 31e can improve the overall seating and improve the mechanical stability when the adhesive is filled or used, and the pressing portion 31g is formed via the thin portion 31f. The container body 1 through the pressing portion 31g.
It is possible to push and operate the bellows structure of the bottom 11b.

As described above, according to the present invention, the container body, the inner cap, and the outer cap are combined, and the inner cap and the outer cap are integrated with each other through the sealing tip of the nozzle portion, By forming a liquid stop portion on the inner peripheral surface of the outer cap, the outer cap can twist the sealing chip from the thin portion by rotating the outer cap, and thus there is a danger of the adhesive being ejected. The nozzle can be easily opened without any trouble, and after use, the outer cap is re-attached to the inner cap, so that the liquid stop comes into close contact with the outer peripheral surface of the nozzle and the nozzle is completely re-mounted. There is an excellent effect that sealing can be performed.
