Description

  The present invention relates to a method for producing a moisture-curable paste-like article packaging body, in which a moisture-curable paste-like article is filled inside, a nozzle body is attached to the tip, and the moisture-curable paste-like article inside can be extruded, and moisture curing The present invention relates to a paste-like article packaging body.

  Conventionally, for example, a package described in Patent Document 1 is known as a package having a moisture-curable paste-like article filled therein. The packaging body described in Patent Document 1 is a moisture curable caulking agent packaging body obtained by packaging a moisture curable caulking agent with a flexible packaging material, and the packaging material is aluminum having a thickness of 7 μm to 15 μm. A heat-sealable thermoplastic resin film having a thickness of 15 μm to 50 μm is laminated on the front and back surfaces of the foil, and the overall thickness is a packaging material having a thickness of 37 μm to 115 μm. The both end portions in the width direction are overlapped so that the front and back surfaces are opposed to each other, and the overlapping portions are continuously welded, and the inside of the packaging material is filled with the moisture-curable caulking agent, and the length of the packaging material is It is a package of a moisture curable caulking agent formed by ligating both ends in the vertical direction with a line material.

  The package as described in Patent Document 1 is loaded into a jig called an extrusion gun or a caulking gun, and a moisture-curable paste-like article such as a caulking agent is extruded from the inside. A technique for loading a sausage-type film pack filled with such a moisture-curable paste-like article into an extrusion gun or the like and extruding the contents is currently widely performed at construction sites and the like.

  In this sausage type film pack, the film pack is stored in a cylinder body (or cylindrical adapter), the sausage type film pack stored in the cylinder body is pushed out, the rod is advanced and pressed by a pressing plate, and the inside of the film pack is A sealing material or the like is discharged from the nozzle. As a sausage type film pack type extrusion gun, for example, the applicant of the present application has already proposed the invention shown in Patent Document 2.

  In addition, a cartridge type extrusion gun can be used to extrude and discharge sealing material from a sausage type film pack. If there is a cartridge type extrusion gun, a sausage type film pack type extrusion gun can be purchased and used separately. The present applicant has already proposed the invention shown in Patent Document 3 as an extruding mechanism for a film pack that is not necessary.

  On the other hand, a soft cartridge container or the like in which the cartridge container is made of a soft material and the cartridge container can be compactly compressed has been proposed (Patent Document 4 and Patent Document 5).

  Moreover, what was described in patent document 6 as a sealant accommodation pouch which can be loaded in an extrusion gun without using a hard cartridge container is also known. The sealant-containing pouch described in Patent Document 6 is a film pack type with a nozzle in which a nozzle is detachably provided on one side of the sausage type film pack as described above.

  However, when manufacturing the above-described soft cartridge container, for example, in Patent Document 4, as shown in FIG. 2 of Patent Document 4, a molding space of a lower molding portion is passed through a runner from a gate port provided in a mold. By injecting a synthetic resin material such as polyethylene resin into the molding space of the upper molding portion in a molten state by means of insert injection molding means, the upper molding portion and the lower molding portion are integrally coupled to the intermediate barrel portion, thereby A cartridge having a lower end opening is manufactured (see paragraph 0015 of Patent Document 4 and FIG. 2 of Patent Document 4).

  However, if the upper molding part and the lower molding part are integrally coupled to the intermediate body by the above-described method, it takes a lot of cost and labor in manufacturing.

  Further, when producing the sealant-containing pouch described in Patent Document 6, first, a cylindrical body in which a gas barrier sheet having a thermoplastic synthetic resin film layered on both sides of an aluminum foil is rolled and both ends in the width direction are thermally bonded. A gas barrier disc having both sides of an aluminum foil layered with a thermoplastic synthetic resin film has a peripheral side wall, and the peripheral side wall is fitted to the upper part of the cylindrical body to heat the thermoplastic synthetic resin films together. A canopy that is bonded and integrated with the cylinder, and a synthetic resin pedestal that has a discharge cylinder and is thermally bonded to the surface of the canopy, and then fills the cylinder with a sealant, and finally Ligation or thermocompression bonding is performed by a rear opening clip of the cylindrical body (see the embodiment of the invention of Patent Document 6 and FIGS. 3 and 4 of Patent Document 6).

  However, producing the sealant-accommodating pouch by the method as described above is costly and laborious in production, and the sealant is filled after producing the cylinder and the like, so that the filling operation is difficult. is there.

  That is, the moisture curable paste-like article packaging body 10 of the present invention surrounds the clip member 22 at one end of the sausage type packaging body 24 after producing the sausage type packaging body 24 similar to the prior art. The nozzle body mounting portion 26 is formed of a thermoplastic resin by an injection molding process and has a very simple structure. For this reason, there is an advantage that the manufacturing cost can be reduced. In addition, it may be used by being loaded into an extrusion gun in the state shown in FIG. 5, or it can be used by hand drawing in the state shown in FIG. The moisture curable paste-like article 14 is a sealing material or an adhesive.
