Abstract

PROBLEM TO BE SOLVED: To surely fill a filler even into the region such as the internal angle where there is an obstructive protrusion in the cylindrical discharge nozzle to be attached to the tip of the cartridge of filler, etc., by providing a flexible bending part close to its tip. SOLUTION: When a trigger 32 provided in front of the handle 31 in a caulking gun is pulled toward an operator, an extruding rod 34 provided on the rear end of a main body 33 is moved forward to press the filler, etc., in a cartridge 20, and hence a necessary amt. of the filler, etc., is continuously discharged from a discharge port 11 at the tip of a discharge nozzle 10. The discharge nozzle 10 is integrally formed with a PE resin, etc., and tapered into a conical shape. In this case, a flexible bending part 12 is provided close to the discharge port 11 in the nozzle 10, the tip of the nozzle 10 is bent through the bending part 12 to hold the discharge port 11 at an optional angle to the cartridge 20, and nonuniform coating and insufficient filling are prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall of a building or a filler used for discharging a filler or the like, which is attached to the tip of a cartridge in which a filler or the like used for waterproofing of housing equipment is enclosed. The present invention relates to an agent discharge nozzle.

[0002]

2. Description of the Related Art Conventionally, a waterproof treatment for an outer wall of a building, a housing facility, etc. is carried out by filling a required portion while dispensing a required amount from a cartridge in which a filler or the like is enclosed.
At the tip of the cartridge, a discharge nozzle is attached and used in order to improve the workability of filling.

As shown in FIG. 6, the shape of the above-mentioned discharge nozzle is generally such that a discharge opening 200 is provided at the tip of a cylindrical main body 100 which has a conical shape tapering toward the tip. The rear end 300 is inserted from the outside into a mounting port 400 of a cartridge (not shown) and is used in a crimped state.

[0004]

However, in the conventional nozzle, since the nozzle is formed in a straight line as described above, for example, as shown in FIG.
A protrusion 8 such as a sash frame is provided directly on the corner 700 of the 600.
If 00 exists, the entry corner 700 that is the filling point
In the discharge nozzle shown in FIG. 6, although discharge is possible,
There is a problem in that the ejection port 200 at the tip of the nozzle does not reach the entering corner 700 as desired, or the angles do not match, so that filling cannot be completed completely. In other housing equipment and the like, for example, the same problem as described above also remains in the corners of the boundary between the bathtub and the wall surface of the bathroom.

The present invention has been made in view of the above problems, and an object of the present invention is to solve these problems and to prevent an obstruction due to a projecting portion at the entry corner. It is intended to provide a filler discharge nozzle capable of reliably filling a filler or the like even in such a place.

[0006]

The filler discharge nozzle of the present invention is a cylindrical filler discharge nozzle that is detachably attached to the tip of a cartridge and is used in the vicinity of the tip of the nozzle. It is characterized in that a flexible bent portion is provided.

(Function) In the filler discharge nozzle of the present invention, since the flexible bent portion is provided in the vicinity of the tip of the nozzle, the discharge port of the nozzle can be freely bent at the required angle. Even if there is a protruding portion at the entering corner and it is an obstacle, the filler or the like can be reliably filled.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing an example of a nozzle for discharging the filler of the present invention. In FIG. 1, the ejection nozzle 10 is used by being attached to the tip of a cartridge 20 in which a filler, an adhesive, or the like is enclosed. Further, the cartridge 20 is adapted to be used by being mounted on the caulking gun 30.

That is, the handle 31 of the caulking gun 30.
When the trigger 32 provided on the front side of the cartridge 10 is pulled to the front side, the pushing rod 34 provided on the rear end of the main body 33 advances and presses the filler and the like in the cartridge 20, so that the discharge port at the tip of the nozzle 10 From 11, the required amount of filler or the like is continuously discharged.

FIG. 2 is a side view showing the details of the discharge nozzle 10. In FIG. 2, the discharge nozzle 10 is
A cylindrical shape integrally molded using a polyethylene resin or the like is preferably used. The discharge nozzle 10 is
The bent portion 12 is made of a conical tubular body that tapers toward the tip side and has flexibility near the discharge port 11 at the tip.
Is provided. At the rear end, a mounting opening 13 having a diameter increased for mounting on the front end of the cartridge 20 is provided.

As shown in FIG. 2, the bent portion 12 is normally reduced, but by pulling it, as shown in FIG. 3, a sharply bent corner 12a of a mountain portion and a corner of a valley portion are formed. 12b is extended to be in an obtuse angle state and has a property of retaining this state when left unattended.

Further, as shown in FIG. 4, when the tip end side having the discharge port 11 is bent at an arbitrary angle, the bent angle state is maintained. In this bent state, that is, in a state in which the ejection port 11 is held at an arbitrary angle α with respect to the cartridge 20, the filler can be ejected with an appropriate angle, so that uneven coating and insufficient filling can be prevented. It

FIG. 5 is a plan view showing a usage example of the filler discharging nozzle of the present invention. In FIG. 5, a sash frame 42 projects from a wall surface 41 of an outer wall 40 of a house or the like, and a filler 45 is placed in a gap 45 between the wall surface 41 and an end surface 44 of a wall body 43 that abuts the wall surface 41 at a right angle. This shows the case where 46 is filled and waterproofing is performed.

When the cartridge 20 mounted on the caulking gun 30 is approached in parallel along the wall 43, the discharge nozzle 10 at the tip is inserted into the gap between the wall 43 and the sash frame 42. . At this time, the discharge port 1 is bent in advance in a direction to fill the bent portion 12 of the discharge nozzle 10.
Make sure that 1 reaches the filling section sufficiently.

By doing so, when the rear end of the cartridge 20 is pressed by the pushing rod 34 of the caulking gun 30, a necessary amount of the filler is discharged from the discharge port 11 and is filled in the gap 45 to ensure a waterproof property. It can be processed.

[0016]

In the filler discharge nozzle of the present invention, since the flexible bent portion is provided in the vicinity of the tip of the nozzle, the discharge port of the nozzle can be freely bent at the required angle, Even at a corner portion or a portion where the protruding portion interferes, the filler or the like can be surely applied and filled. Therefore, it is suitable as a filler discharge nozzle.
