DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package of a moisture-curable caulking agent and a packaging apparatus for producing the package. More specifically, the present invention relates to a moisture-curing jig called a caulking gun. The present invention relates to a curable caulking agent package and a packaging apparatus for producing the same.

[0002]

2. Description of the Related Art Conventionally, a moisture-curing caulking agent is usually applied to a work surface such as a joint using a caulking gun.
It has been practiced to form a rigid plastic cylindrical container in the form of packaging.

However, in response to the recent demand for resource saving, a rigid plastic container is not disposable but a soft plastic package is supplied instead. And, since the caulking agent is moisture-reactive, the packaging material constituting the soft plastic package is required to have a moisture-proof property and a certain strength.
Further, in order to facilitate the discharge of the caulking agent by the caulking gun, and to reduce the remaining amount of discharge and minimize the waste volume after use, use of a highly flexible packaging material is required. .

[0004] The main proposals on the technology for improving the moisture-proof property of a soft plastic package of a moisture-curable caulking agent are as follows. That is, Japanese Patent Publication No. 59-334
No. 5 discloses a moisture-curable caulking agent filled in a cylindrical container made of a flexible resin film, and the open end of the cylindrical container is ligated and sealed to form a package. A room temperature moisture-curable one-part sealant package for a caulking gun has been disclosed, which is covered with a film or an aluminum vapor-deposited film, and the periphery of the outer film is bonded by heating or an adhesive to hermetically seal the inside. This technology aims to solve the problems of moisture proofing, reduction of the remaining amount of discharge and reduction of the volume of waste, but specific comparisons or descriptions of the effects on reduction of the remaining amount of discharge and reduction of the volume of waste. There is no.

[0005] Japanese Patent Application Laid-Open No. 61-227037 discloses that a room temperature moisture-curable one-component is prepared in a cylindrical container of a flexible aluminum laminated film in which a polyethylene film, a polyamide film, an aluminum foil and a polypropylene film are laminated. A room temperature moisture-curable one-component sealing agent package for a caulking gun, which is filled with a system sealing agent in a dry nitrogen gas stream and hermetically heat-sealed both open ends of the cylindrical container, is disclosed. Also in the technology, there is no specific comparison or effect on reduction of the discharge remaining amount or reduction of the volume of waste.

[0006]

SUMMARY OF THE INVENTION The present inventors have developed a cartridge-type moisture-curable caulking agent package which has the moisture-proof properties required for caulking storage, reduces the discharge residual amount and reduces the waste volume. As a result of intensive studies on volume reduction, the present inventors have found that a specific packaging material, a superimposed structure of the specific packaging material and a package obtained by a welding method thereof are effective, and have completed the present invention.

[0007]

According to a first aspect of the present invention, there is provided a package of a moisture-curable caulking agent, wherein the moisture-curable caulking agent is packaged with a flexible packaging material. In the packaging body, the packaging material is formed by laminating a heat-sealable thermoplastic resin film on the front and back surfaces of an aluminum foil, and the packaging material is formed into a cylindrical shape, and both ends in the width direction are formed by these. Are superimposed so that the front and back surfaces face each other, and these superposed portions are continuously welded, and the inside of this packaging material is filled with the moisture-curable caulking agent, and both ends in the length direction of the packaging material are linearly formed. it was ligated with wood, the superimposed
The width of the mating part in the circumferential direction is 5 mm to 20 mm
It is characterized by.

Here, the aluminum foil has a thickness of 7 μm to 15 μm, preferably 9 μm to 12 μm.
μm is used. Such a range is because
If the thickness is less than 7 μm, pinholes are likely to occur due to bending or ligating with a striated material, and there remains a problem with moisture proofness. If the thickness exceeds 15 μm, the flexibility required for volume reduction is secured. It is because it is not done.

As the heat-sealable thermoplastic resin film, for example, a heat-sealable polypropylene is laminated on a single-layer film such as a high-density polyethylene film, an unstretched polypropylene film, an unstretched nylon film, and a stretched polypropylene film. Examples thereof include a film, a film obtained by laminating a heat-sealable low molecular weight polyethylene terephthalate film on a polyethylene terephthalate film, and a multilayer film such as a two-layer film of a polyethylene film and an unstretched polypropylene film. Its thickness ranges from 15 μm to 50 μm, preferably from 15 μm to 40 μm. It is 15 μm to be laminated on the front and back surfaces of the aluminum foil in such a range.
When the diameter is less than m, pinholes in the aluminum foil are likely to occur due to ligature or the like by the striated material, and when it exceeds 50 μm, the flexibility of the packaging material cannot be ensured.

Further, the welding is performed by overlapping the front and back surfaces of the both ends of the packaging material by minimizing the number of laminations at the joining portion of the both ends of the packaging material and securing the flexibility at this joining portion. , For facilitating volume reduction, and the preferable overlapping width is set to 5 mm to 20 mm. This is 5
If it is less than 20 mm, sufficient sealing strength cannot be secured, and if it exceeds 20 mm, the duplexed portion becomes large and it becomes difficult to secure flexibility, so that the waste volume after use is reduced. This is because it cannot be reduced.

Further, in consideration of maintaining the airtightness and handleability at the time of ligating, aluminum wire is preferably used as the wire material, and its wire diameter is determined by the shape and thickness of the applied packaging material. 2.9mm ~ 4.0mm
Is used.

Further, according to a second aspect of the present invention, apparatus for packaging moisture-curable caulk, molding the packaging material on the front and back surfaces of the aluminum foil formed by laminating a heat-sealable thermoplastic resin film into a cylindrical shape And a homer for overlapping both ends in the width direction such that the front and back surfaces thereof face each other, welding means for continuously welding the overlapped portion, and moisture inside the cylindrically shaped packaging material. Filling means for filling the curable caulking agent, and by squeezing the moisture-curable caulking agent-filled packaging material from the outside, the moisture-curing caulking agent inside is separated in the length direction of the packaging material. Ironing means, and a ligating means for sealing the squeezed portion of the packaging material from which the moisture-curable caulking agent is separated by the ironing means, and the filling means,
A filling nozzle inserted into a cylindrically shaped packaging material, a filling pump for pressure-feeding a moisture-curing caulking agent to the filling nozzle, and a moisture-curing caulking agent stored and moisture-cured to the filling pump. A surge tank for supplying a caulking agent and a surge tank
Pressurizing means for reducing a negative pressure generated in the moisture-curable caulking agent stored therein by introducing an inert gas .

[0013]

According to the package of the moisture-curable caulking agent according to the first aspect of the present invention, by using a packaging material in which a heat-sealable thermoplastic resin film is laminated on the front and back surfaces of an aluminum foil, While ensuring sufficient flexibility, aluminum foil ensures moisture-proof properties,
Further, the damage of the aluminum foil is prevented by the thermoplastic resin film.

Further, by welding the both ends so that the front and back surfaces thereof face each other, the internal pressure acting on the seal portion is in the shearing direction, and the strength is secured.
Furthermore, since the thermoplastic resin film can be heat-sealed, a cylindrical container can be easily obtained by sequentially heat-sealing the overlapping portions of the packaging material. Therefore, the moisture resistance and the strength are ensured by the package body alone.

According to the packaging apparatus for a moisture-curable caulking agent according to the second aspect of the present invention, the packaging material is formed into a cylindrical shape by being passed through a homer, and both ends of the packaging material have front and rear surfaces. They are superposed in a state of facing each other. When the packaging material is further moved from this state, the overlapping portion is heat-sealed by welding means, so that the overlapping portion is firmly connected.

Thus, the filling pump sucks the moisture-curable caulking agent in the surge tank and sends it to the filling nozzle under pressure, so that the moisture-curing caulking agent is filled inside the packaging material and then packed. Both ends of the material are ligated by ligating means to produce a package. When the moisture-curable caulking agent is filled, the internal pressure in the surge tank is reduced by the suction action of the filling pump, but the internal pressure is suppressed by the pressurizing means provided in the surge tank. This prevents moisture from entering the moisture-curable caulking agent in the surge tank.

A raw material roll 3 on which a packaging material 2 formed by laminating possible thermoplastic resin films is wound, and the packaging material 2 pulled out from the raw material roll 3 is formed into a cylindrical shape. Both ends 2a in the width direction of
2b, and a superimposed portion A of the packaging material 2 (FIG. 2).

Ligating means for hermetically sealing the container, wherein the filling means comprises a filling nozzle inserted into a cylindrically shaped packaging material, and a moisture-curing caulking Filling pump that pumps the agent, a surge tank that stores the moisture-curing caulking agent and supplies the moisture-curing caulking agent to the filling pump, and a moisture-curing agent that is provided in this surge tank and stored inside. Negative pressure generated in caulking agent is introduced by inert gas
And a pressurizing means for reducing the amount of moisture-curable caulking agent.
