The present invention relates to an improved joint material filling cartridge which is filled with joint materials to be injected into joints around a sash and other joints.

[0002]

2. Description of the Related Art As shown in FIG. 17, a nozzle detachable type cartridge, which is already known as this type of joint filler, closes a front end opening of a cylindrical container 1 with a front end plate 2 and a rear end opening. Is closed by a rear end plate 3, and a joint material 5 is filled between the seal member 4 such as an aluminum film stretched at a position close to the inner end of the front end plate 2 and the rear end plate 3, and at the time of joint construction, ,
A sharp member such as a nail is inserted through a nozzle attachment port 6 provided in the front end plate 2 to break through the seal member 4 and
And, the tapered side of the injection nozzle 7 which is separately molded into a tapered blind end is cut off at a required portion having a diameter that fits the joint width,
The injection nozzle 7 is attached to the nozzle attachment port 6, and the entire cartridge with the injection nozzle 7 attached is
It is used by loading it into a known filling gun prepared separately.

In the nozzle integrated type, as shown in FIG. 18, the front end opening of the tubular body 1 is closed by the front end plate 2 and the rear end opening is closed by the rear end plate 3, and the inside of the front end plate 2 is closed. Filling the joint material 5 between the sealing material 4 such as an aluminum film stretched in one direction and the rear end plate 3 and injecting it into a tapered blind end type integrally formed with the substrate 8 superposed on the inner surface of the front end plate 2. Replace the nozzle 9 with the front end plate 2
Of the injection nozzle 9 is cut out at a required portion having a diameter corresponding to the joint width, and is then opened. After penetrating the sealing material 4 by inserting a sharp member such as the above, the entire cartridge is loaded into a separately prepared well-known filling gun for use.

[0004]

That is, in the conventional joint material filling cartridge, in both the nozzle detachable type and the nozzle integrated type, in actual joint construction, the sealing material stretched in the cylindrical body is used. There is a disadvantage in that it is necessary to pierce or cut off the injection nozzle at a portion having a diameter matching the joint width, and the operation is troublesome.

[0005] Injecting the joint material into the joint is performed directly from the injection nozzle to the joint, and thereafter, the extruded joint material is scraped off using a metal finishing vera such as stainless steel or steel, and the joint material is scraped off. The flattening of the surface has the disadvantage that the required finishing must be achieved. To extend this, direct injection from the injection nozzle tends to cause an excess or deficiency in the injection amount, especially by unskilled workers. In addition to the drawbacks, there is a disadvantage that the pouring operation and the finishing operation must be performed separately, and both the pouring operation and the finishing operation require considerable skill.

[0006] A main object of the present invention is to make it possible to immediately inject a joint material without performing the above-mentioned work of piercing the seal material and cutting off the tip of the injection nozzle. Another object of the present invention is to make it possible to perform surface finishing at the same time as the injection of the joint material, and that it can be performed easily, reliably, and well by a beginner.

[0040]

As is apparent from the above description,
The present invention has the following effects. The sealant filling cartridge of the present invention is loaded into a filling gun, and the operating lever of the filling gun is initially operated to press the sealing material through the jointing material in the tubular body, thereby making a cut in the sealing material. Since the joint material is pushed out by breaking the seal material largely by the subsequent turning operation of the operation lever, there is no trouble to break through the seal material by using a sharp member such as a nail in advance as in the conventional case.

Further, when the finishing device is attached to the nozzle, the operating lever of the filling gun is rotated while maintaining the state where the finishing device is positively pressed to the joint side with a required pressing force. By pushing out the joint material,
And just pull the filling gun forward along the joint,
Since the joint material can be successively injected into the joint and finish leveling can be performed, predetermined injection and finish leveling can be carried out in a good manner even for a beginner.

That is, in the conventional joint material filling cartridge, whether the nozzle is removable or the nozzle integrated type,
In the actual joint work, the sealing material stretched inside the cylindrical body is pierced in advance with a sharp member such as a nail, and the surface finish leveling of the injected joint material is called the injection work. Although it had to be performed separately, the present invention obviates the need for these operations, and the merits of improving the efficiency of jointing work and reducing costs by this are extremely large.
