Description

[Detailed Description of the Invention] The present invention relates to a cap that is attached to a container for caulking agent that is filled into gaps and holes at the joints of building structures to prevent water leakage.

(Prior Art) Generally, in construction, caulking (made of silicone resin, etc.) is used to prevent rainwater from entering indoors through holes in walls for bolt attachments or gaps between joints of roof panels. It is filled with a sealant and cured into a rubber-like form to make it waterproof.

As shown in Fig. 5, this caulking agent is filled into a cylindrical container 2 fitted with a movable bottom lid 1, and extruded from a conical nozzle 3 provided at the tip of the container. .

When waterproofing is carried out at a construction site, as shown in Fig. 6, a cartridge-type container 2 is set in a caulking gun 4, the nozzle 3 at the tip is cut at an arbitrary point to open it, and the lever 5 is pulled. Rod 6
moves forward little by little and pushes the bottom cover 1, and the caulking agent 7 filled inside is pushed out from the tip of the nozzle 3 and used.

In this case, since the width of the part to be waterproofed varies depending on the site, the user can adjust the diameter through which the caulking agent 7 is extruded by cutting the tip of the nozzle 3 made of plastic at an arbitrary location. ing.

In order to change the diameter of the nozzle 3 depending on the location of use, conventionally no cap was provided to attach it to the nozzle 3, and the user had to pick up nails 8 or bolts from the site as shown in Figure 7. It was used instead of a plug at the tip.

However, since there are few cases in which the diameter of the nozzle 3 matches the outer diameter of the stopper, if it is not used for a while, the liquid caulking agent 7 will come into contact with air and gradually harden into a rubber-like state, resulting in a wedge-shaped hardened portion 9. The problem was that it formed and hardened inward, making it unusable.

(Problems to be solved by the invention) The present invention has been devised in view of the above points, and it reliably seals a nozzle cut to an arbitrary diameter to cut off contact with air, so that the nozzle can be used for a long period of time. To provide a nozzle cap for a caulking agent container that can prevent the caulking agent from hardening inside.

(Means for solving the problem) The present invention consists of a cap body that is detachably attached to a nozzle at the tip of a container filled with caulking agent, and a cap body that is inserted into the inside of this cap body, with the opening side facing the inner wall of the cap body. A cap-shaped sealing body made of a soft material and connected to the cap body, a rod-shaped plug connected to the tip of the sealing body and attached so as to be able to go in and out through the tip of the cap body, and the cap body. It is characterized by comprising an air hole which is opened in the inner wall and communicates with the gap between the inner wall and the sealing body.

(Function) When the nozzle cap of the present invention is placed over a nozzle cut to an arbitrary diameter and the stopper is pushed in, the tip of the sealing body, which is attached to the inside of the cap body and integrally connected to the stopper, gradually becomes depressed. Then, the tip of the stopper and the sealing body close the opening of the nozzle to isolate it from air.

In this case, the sealing body is made of a soft material, and the amount of recess can be freely adjusted, so that it can be reliably closed according to the diameter of the nozzle.

Furthermore, since the air holes are opened, the sealing body does not become under negative pressure and can freely deform as the plug advances.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 3.

Reference numeral 10 denotes a cap body, which is formed in the shape of a truncated hollow cone, and is adapted to be detachably attached to the tip of the nozzle 3.

Reference numeral 11 denotes a cap-shaped sealing body made of soft plastic or rubber, and is inserted inside the cap body 10. The opening side of this sealing body 11 is a stepped portion 10b of the inner wall 10a of the cap body 10.
The outer periphery is joined to the outer periphery.

Reference numeral 12 denotes a bolt-shaped plug, and the tip of the sealing body 11 is held between a conically pointed tip 13 and a tip of a threaded portion 14 . Further, the threaded portion 14 passes through a threaded hole 15 formed at the tip of the cap body 10, and the plug 12 is attached so as to be freely inserted and removed.

Reference numeral 16 denotes an air hole opened near the tip of the cap body 10, which communicates with a gap 17 between the inner wall 10a of the cap body 10 and the sealing body 11.

Reference numeral 18 denotes two plate-shaped locking pieces extending from the tip of the cap body, and an engaging portion 19 provided on the side wall of the nozzle 3.
The cap is connected to the cap by removably engaging with the cap.

The nozzle cap of the above structure is sold attached to the nozzle 3, and when used, the nozzle cap is removed and the caulking gun 4 is installed as shown in Figure 6.
and cut the tip of the nozzle 3 at a desired position for use.

When the work is finished, as shown in Figures 1 and 2, cover the nozzle cap and screw in the stopper 12, the sharp tip 13 will bite into the tip of the nozzle 3, blocking it, and the caulking agent 7 inside will be removed. leaks out a little.

At this time, since the stopper 12 and the sealing body 11 made of a soft material are integrally connected, the tip of the sealing body 11 is recessed inward to cover the opening of the nozzle 3 and shut off from air. In this case, since the air holes 16 are formed, air is sucked into the gap 7 and no negative pressure is created, allowing the sealing body 11 to freely deform and dent.

Furthermore, when the nozzle 3 is cut long and has a large diameter, the amount of recess of the sealing body 11 increases accordingly, as shown in FIG. 3, and the sealing body 11 enters the opening to ensure that air can be blocked.

FIG. 4 shows another embodiment of the present invention, in which the plug 12 is formed into a round bar shape, and a cylindrical portion 20 having a threaded portion 14 on the outer periphery is attached to the tip of the cap body 10. A longitudinal slit 21 is provided in the slit 21, a nut 22 is attached thereto, and the slid plug 12 is tightened and fixed at an arbitrary position.

Further, the cap body 10 and the sealing body 11 are not limited to being formed of different materials and joined together, but may be formed integrally of the same material.

Further, as a method of fixing the cap body 10 to the nozzle 3, a screw-in type or a push-in type structure may be used.

(Effects of the invention) As explained above, according to the nozzle cap for a caulking agent container according to the present invention, a nozzle cut to an arbitrary diameter is reliably sealed with the stopper and sealing body, thereby blocking contact with air. However, it is possible to prevent the caulking agent from curing inside the nozzle for a long period of time.
