【Example】

 Hereinafter, the ejection device cartridge and the ejection device of the present invention will be described in detail with reference to embodiments. 1 to 5 are views showing an embodiment of a discharging device of the present invention, and in these drawings, reference numeral 1 is a discharging device. As shown in FIG. 1, the discharging device 1 comprises a cartridge 2, a cylindrical body 3 into which the cartridge 2 is inserted, and a gun body 4.

As shown in FIG. 2, the cartridge 2 has a caulking material A filled in a tube 5, and has a locking portion 5a formed at one end and a nozzle portion 5b formed at the other end. It was the one. The locking portion 5a is formed by bending and crimping the end of the tube 5 a plurality of times, and is formed in an oblique direction with respect to the axis of the tube 5. The nozzle portion 5b converges and discharges the caulking material A in one direction, and is formed so as to gradually become thinner toward the end portion. The tube 5 is a laminated tube in which, for example, cellophane, paper, aluminum foil, polyethylene sheet, and vinyl acetate sheet are laminated from the inside.

As shown in FIG. 3, the cylindrical body 3 has a retaining portion 6 formed at its end, and the cap 7 is inserted after the cartridge 2 is inserted. The retaining portion 6 is formed in an oblique direction with respect to the axis of the cylindrical body 3 similarly to the retaining portion 5a of the cartridge 2, and is a slit-like cut in which the vicinity of the retaining portion 5a is sandwiched. . The cap 7 is a cylindrical body with a bottom, and is adapted to enter the cylindrical body 3 and press the cartridge 2 against the inner wall of the cylindrical body 3. The outer diameter of the cap 7 is slightly smaller than the inner diameter of the cylindrical body 3, and is a size that allows the cartridge 2 to move without difficulty while being crushed and pressed against the inner wall of the cylindrical body 3.

As shown in FIG. 1, the gun body 4 includes a piston portion 8, a pushing mechanism 9 for driving the piston portion 8, and a housing portion 10. The piston portion 8 is connected to the pushing mechanism 9, and the front end portion of the piston portion 8 contacts the cap 7. The pushing mechanism 9 can move the piston portion 8 forward by pulling the lever 9b of the grip portion 9a. The storage unit 10 stores the cylindrical body 3 into which the cartridge 2 is inserted, and includes a semi-cylindrical portion 10a having a shape obtained by cutting the cylinder in half in the axial direction, and a plate 10b formed at the front end of the storage unit 10. It consists of The semi-cylindrical portion 10a is for accommodating and accommodating the cylindrical body 3 through the opening 10c formed on the side surface, and has an inner diameter substantially the same as the outer diameter of the cylindrical body 3. As shown in FIG. 5, the plate 10b has a disk formed with a U-shaped cutout portion 10d for allowing the nozzle portion 5b of the cartridge 2 to project forward from the storage portion 10.

In order to discharge the caulking material A by using the discharging device 1 having the above-described structure, first, the cartridge 2 is inserted into the cylindrical body 3 and, as shown in FIG. Inserting the cap 7 from the side of the retaining portion 6 of the cylindrical body 3 is set so that the locking portion 5a remains outside the retaining portion 6 while sandwiching the vicinity of the portion 5a. Next, the piston portion 8 of the gun body 4 is moved rearward, the cylindrical body 3 in which the cartridge 2 and the cap 7 are inserted is housed in the housing portion 10 of the gun body 4, and the U-shaped notch portion at the front end of the housing portion 10 is housed. The nozzle portion 5b is projected forward from 10d. Next, an appropriate position of the nozzle portion 5b, that is, a position where the caulking material A is discharged with a desired thickness is cut off, and the lever 9b of the pushing mechanism 9 is pulled to move the piston portion 8 forward. The caulking material A is discharged. Further, the replacement of the cartridge 2 in such a discharge device 1 is performed by moving the piston portion 8 rearward, removing the cylindrical body 3 in which the cartridge 2 and the cap 7 are inserted from the gun body 4, and replacing the cartridge 2. Is.

According to the discharge device 1 having such a configuration, the cartridge 2 can be manufactured at a lower cost than the conventional metal cylindrical cartridge, has flexibility, and has sufficient strength against pressing. Therefore, the caulking material A can be continuously discharged by pulling the lever 9b of the pushing mechanism 9. Further, since the nozzle portion 5b of the cartridge 2 is passed through the U-shaped cutout portion 10d at the front end of the storage portion 10, the nozzle portion 5b hardly moves and the caulking material A coating operation is easy. Further, the cartridge 2 can be easily replaced, and after the replacement, only the crushed cartridge 2 needs to be discarded, which facilitates transportation and the like in the post-treatment. Further, since the cartridge 2 is a laminated tube having a good shielding property as a packaging material, it can be stored for a long period of time. Further, if the conventional gun body is configured as shown in FIG. 1, the gun body can be used.

The retaining portion 6 is not limited to the slit-shaped notch, and the retaining portion 5a is inserted into the cylindrical body 3 when the cap 7 is moved, such as a groove into which the retaining portion 5a is fitted. Any structure may be used as long as it is held at the end of the.

[0014]

[Effect of device]

 According to the cartridge and the discharging device of the present invention, the cartridge can be manufactured at a lower cost than the conventional cylindrical cylinder made of metal, and the locking portion of the cylindrical body holds the locking portion of the cartridge. It is possible to continuously discharge an amount of caulking material according to. Further, after the cartridge is replaced, the crushed cartridge may be discarded, which facilitates transportation and the like in the post-treatment.
