Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of a cap attached to a double-structured adhesive container in which an inner container with a nozzle is accommodated in an outer case.
[0002]
[Prior art]
As one of the containers of cyanoacrylate-based instant adhesive, after filling and sealing the instant adhesive in the inner container with nozzle, it is accommodated in the outer case, and the cap is engaged with the upper part of the outer case Is known.
[0003]
That is, in Japanese Patent Publication No. 7-49308 (Japanese Patent Laid-Open No. 5-294371), a flexible elastic bottle inside container filled with an adhesive solution and an upper end outlet port of the inside container are projected and stored outside. A one-push squeeze type double structure type adhesive packaging container comprising a squeeze-type flexible elastic outer case main body and a crown cap is shown. The container having this structure has an advantage that the middle container is protected by the outer case body and the discharge operation is performed by the clamping pressure of the outer case body, so that a necessary amount can be discharged by a soft touch. (Note that all the technologies and sales of the applicant of this publication are now taken over comprehensively by the applicant.)
[0004]
In the container of the above publication, as a suitable example of the cap cap, there is a structure in which a holed member with a pin is detachably fitted into a recessed fitting part that is provided. When the container is used for the first time, the cap of the cap is first picked with a finger and removed from the main body of the outer case, and then the dripping spout of the inner container is pushed and sealed by the pin of the pinned hole member. When the adhesive dripping operation is interrupted, sealing can be achieved by pushing the pin of the hole member into the dripping port of the middle container. When cleaning up after use, it is only necessary to push the crown cap tightly into the exterior case body. The pinned hole member is fitted in the recessed fitting portion of the crown cap.
[0005]
[Problems to be solved by the invention]
In the container of the above-mentioned Japanese Patent Publication No. 7-49308, paying attention to the crown cap, since the pinned hole member can be fitted into the concave fitting portion of the crown cap, The pinned hole member can be prevented from being lost regardless of whether it is in use, and further, there is an advantage that it is safe because the danger of piercing the finger by the pin can be prevented.
[0006]
However, when the container is used for the first time, the tear outlet of the middle container must be broken by pinching the pinned hole member with your finger and squeezing it well into the drop outlet. However, such detailed work is troublesome, and is particularly burdensome for people whose naked eyesight has deteriorated in the middle and old age. Also, as time passes after use, the adhesive may solidify at the location of the dripping spout.If the adhesive discharge performance is poor after the next use, remove the spout spout of the middle container. There is an inconvenience that the pin of the holed member with the pin has to be pierced and sealed again.
[0007]
Under such a background, the present invention, by taking advantage of the goodness of the double-structured adhesive container in which the inner container with the nozzle is accommodated in the outer case, as it is, It is an object of the present invention to provide a cap structure for an adhesive container that makes it extremely easy to open with a pin during use and prevents solidification of the adhesive at the nozzle tip during storage after use. .

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail below.
[0010]
<Basic structure>
In the present invention, on the upper side of the outer case (3) of the double-layer adhesive container in which the inner container (2) with the nozzle (2a) is accommodated in the outer case (3), a cap (1) described later is provided. Wear. A typical example of the double-structured adhesive container is the container described in Japanese Patent Publication No. 7-49308 described in the section of the prior art.
[0011]
<Inner container (2) with nozzle (2a), adhesive>
The middle container (2) with the nozzle (2a) is preferably a flexible bottle-shaped container having moderate elasticity, and its basic shape is one end side (upper side) of the cylindrical body (2c). ) Becomes the neck portion (2b), and the nozzle (2a) usually protrudes from the tip of the neck portion (2b). The neck portion (2b) may have a conical cylinder shape with a tapered front end side, or may gradually decrease in diameter toward the front end side. The tip of the nozzle (2a) of the middle container (2) is left blind. The other end side (the lower side) of the cylindrical body part (2c) is sealed in the bottom part (2d) by, for example, filling the inner container (2) with an adhesive and then fitting the bottom cap into the bottom part (2d) for sealing. It is formed.
[0012]
An example of the adhesive that fills the middle container (2) with the nozzle (2a) is an instantaneous adhesive. A representative example of the instantaneous adhesive is a 2-cyanoacrylate-based instantaneous adhesive mainly composed of 2-cyanoacrylate and blended with an appropriate additive as necessary. In addition, an ultraviolet curable instantaneous adhesive is also used.
[0013]
As the material of the inner container (2) with the nozzle (2a), a material that is not affected by the adhesive filled therein and hardly affects the curability of the adhesive is used. When the adhesive is a 2-cyanoacrylate instantaneous adhesive, polyethylene is optimal.
[0014]
<Exterior case (3)>
The outer case (3) is preferably a molded product of flexible plastics (eg, polyethylene or polypropylene) having appropriate elasticity. The outer case (3) is preferably colorless and transparent or colored and transparent so that the inside can be seen through, but may be opaque from the viewpoint of weather resistance. In order to allow the inside to be seen through, a method of installing a window can also be adopted.
[0015]
The outer case (3) is for covering and protecting the whole of the inner container (2) with the nozzle (2a) except for the front end side of the nozzle (2a). In the exterior case (3), one end side (upper side) of the body part (3c) is the neck part (3b) and the cover head (3a), and the other end side (lower side) is the rear part (3d). It is preferable that the structure is of the same type. Each part at this time can have an appropriate shape. A clip such as a fountain pen clip can be attached to the outer case (3).
[0016]
However, when the middle container (2) has a cylindrical shape, the body (3c) has an elliptical cylindrical shape, the neck (3b) has a smaller diameter than the body (3b), and the cover head (3a) has a conical shape. The cylindrical shape and the rear portion (3d) are often smaller in diameter than the barrel portion (3c) and cylindrical. The nozzle (2a) of the middle container (2) protrudes from the cover head (3a). It is preferable to provide a pair of depressions (3e) and (3e) at corresponding portions on both sides of the oval cylindrical body (3c) so that the body (3c) can be pressed and deformed with a finger. In this case, the shape of the recesses (3e) and (3e) is preferably circular, elliptical, oval, etc. from the viewpoint of operation and appearance. The interior of the rear part (3d) can be made hollow and the desiccant can be stored therein.
[0017]
<Cap (1)>
The cap (1) includes a cap body (11) that can be engaged with the upper side of the outer case (3), and a pusher (12) with a pin (12a).
[0018]
Of these, the cap main body (11) is provided with a concave recess (11a) in a longitudinal sectional view from the top surface downward. The shape of the concave depression (11a) is usually a cylindrical shape in a longitudinal sectional view, but may be an elliptical cylindrical shape or a rectangular cylindrical shape depending on circumstances.
[0019]
A hole (11b) having a hole diameter through which the tip of the nozzle (2a) of the middle container (2) can be inserted is provided at the bottom of the concave depression (11a). Then, the hole (11b) is formed in a shade shape having a large diameter on the lower side (like a “C” in a longitudinally cut end view). Furthermore, with respect to the hole (11b) , the entire bottom of the concave depression (11a) is thickened, or only the central region of the bottom is thickened downward, and the hole (11b) is formed in a shade shape. To form . In this case, the latter is advantageous because the thickness is uniform.
[0020]
On the other hand, the pusher (12) with the pin (12a) is slidably fitted in the concave recess (11a) of the cap body (11). In this case, the pusher (12) can be slid, but the pusher (12) fitted in the concave recess (11a) is not loosened, and the pusher (12) does not wobble during the push operation. Design so that it can be pushed straight in.
[0021]
The shape of the body (12b) of the pusher (12) with the pin (12a) is made to match the shape of the concave recess (11a). For example, when the concave depression (11a) is cylindrical, the body (12b) of the pusher (12) is also cylindrical. It is preferable that the head (12c) of the pushing body (12) is formed in a collar part slightly larger than the trunk part (12b) to facilitate the gripping with the fingertip.
[0022]
The lower half of the body (12b) of the push-in body (12) is formed in a hollow cylindrical shape, and the tip of the pin (12a) embedded when the push-in body (12) is molded passes through the hollow part to form the body (12b). It is desirable to reach near the lower end or to make a face appear slightly downward from the lower end.
[0023]
The inner surface of the concave recess (11a) of the cap body (11) or the outer peripheral surface of the pusher (12) with the pin (12a) is provided with a resistance portion (R) that increases the resistance between the two. The pushing body (12) is configured to be able to be pushed in two steps with respect to the shape depression (11a) . An example of the installation mode of the resistance portion (R) at this time is as follows.
[0024]
・ Several ridges are formed in the vertical direction on the inner surface on the lower side of the concave depression (11a).
・ The bottom of the concave depression (11a) is made slightly narrower.
・ Several ridges are formed in the vertical direction on the outer peripheral surface on the upper side of the pushing body (12).
-Make the upper part of the pusher (12) slightly thicker.
[0025]
<Action>
In the present invention, the inner container (2) with the nozzle (2a) filled with an adhesive and sealed is accommodated in the outer case (3), and the cap (1) is associated with the upper side of the outer case (3). The combined product becomes the product form. The assembly work is very easy. A pusher (12) with a pin (12a) is pushed into the concave recess (11a) of the cap body (11) of the cap (1).
[0026]
The inner surface of the concave recess (11a) of the cap body (11) or the outer peripheral surface of the pusher (12) with the pin (12a) is provided with a resistance portion (R) that increases the resistance between the two . Two-stage pushing is possible . For this reason, when the pushing body (12) is pushed in with a constant force during the assembly operation, it can be naturally locked at the resistance portion (R). At this time, although the nozzle (2a) of the inner container (2) has a face upward from the hole (11b) provided in the concave depression (11a) of the cap body (11), the pusher ( The pin (12a) of 12) is slightly away from the tip.
[0027]
When the pusher (12) is further pushed in for the first use, the pin (12a) pierces the tip of the nozzle (2a) of the middle container (2), and the tip of the nozzle (2a) is opened. As described above, the nozzle (2a) of the inner container (2) faces upward from the hole (11b) provided in the concave recess (11a) of the cap body (11). Since the pusher (12) slides straight down in the concave recess (11a) of the cap body (11), the nozzle (12a) ( 2a) The opening at the tip is made securely.
[0028]
After opening the tip of the nozzle (2a), remove the cap (1) from the outer case (3), pinch the outer case (3) with your fingers and press the barrel (3c). The required amount of adhesive is discharged from the nozzle (2a). If the pressure on the body (3c) is stopped, the adhesive that has come out of the nozzle (2a) of the middle container (2) will naturally retreat into the middle container (2) due to the restoring force of the middle container (2). Does not sag.
[0029]
After use, the cap (1) is engaged with the outer case (3). At this time, the tip opening of the nozzle (2a) of the middle container (2) is closed with the pin (12a) of the pusher (12) of the cap (1), so that the sealing is maintained, and the next and subsequent times. In use, the adhesive does not solidify at the tip of the nozzle (2a). For subsequent use, simply remove the cap (1) and perform the same operation.
[0030]
The pusher (12) with the pin (12a) is always in the recessed recess (11a) of the cap body (11), so the pusher (12) with the pin (12a) is lost. And there is no danger of a finger piercing with the pin (12a).
[0031]
The inner container (2) is covered with an outer case (3), so there will be no problem even if unexpectedly large external pressure is applied or sharp objects hit during distribution or storage. .
[0032]
