Abstract

PURPOSE:To provide a container for moisture-setting adhesive in which a sealing material follows true contraction (subsidence) due to decline of temperature of a filling adhesive and the removing work of the sealing material can be omitted on using the adhesive and the adhesive can be prevented from curing and further, the working efficiency can be remarkably increased. CONSTITUTION:A sealing material 10 composed of a paste material having a melting point ranging 35-65 deg.C is applied, about 10mm wide and 5mm thick coating for instance, at the joint of the inner wall face 2a of a container body 2 charmed with an adhesive W with the outer peripheral edge 3a of a vibration proof plate 3 placed on the upper face of the adhesive.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moisture-curable adhesive container, and more particularly, to a moisture-curable polyurethane adhesive container, which is a moisture-curable container having a moisture-proof plate with good airtightness. The present invention relates to a container for a conductive adhesive.

[0002]

2. Description of the Related Art Conventionally, a container for a moisture-curable adhesive is cured when an adhesive filled in the container body absorbs moisture in the atmosphere. Therefore, the container body filled with the adhesive and the container body It is composed of a moistureproof plate that is closely fitted to the inner wall surface and provided with an adhesive supply / discharge hole, and is further covered with a film to seal the inner wall surface of the container body and the outer peripheral edge of the moistureproof plate. A container in which a sealant (one-component urethane) is arranged is proposed at the joint part of (Japanese Utility Model Publication No. 58-4354).
No. 5).

[0003]

However, since the conventional sealant hermetically seals the inner wall surface of the container body and the outer peripheral edge of the moisture-proof plate in a fixed state, for example, when the adhesive agent filled in the container body is at a high temperature. After the adhesive is filled, the adhesive that is filled when the temperature returns to room temperature shrinks, but if the moisture-proof plate and the sealant are used together as described above, the sealant that is cured when the adhesive shrinks Cannot be followed, and therefore a gap is created between the moisture-proof plate and the adhesive surface, and this gap accelerates the curing of the adhesive.When using the adhesive, it is necessary to remove the cured sealant. It was

The present invention has been devised in view of such conventional problems. The sealing material follows the shrinkage (sinking) of the filling adhesive due to the temperature decrease, and the sealing material is removed when the adhesive is used. It is an object of the present invention to provide a moisture-curable adhesive container which can omit work, prevent hardening of the adhesive and can significantly improve the work efficiency.

[0005]

In order to achieve the above-mentioned object, the present invention provides a joint between an inner wall surface of a container body filled with an adhesive and an outer peripheral edge of a moistureproof plate placed on the upper surface of the adhesive. The gist is that a sealing material made of an ointment substance having a melting point of 35 ° C to 65 ° C is filled and applied. Further, petrolatum, petrolatum, wax, paraffin wax, and grease are used as the ointment-like substance of the sealing material, and the sealing material has low moisture permeability and can prevent hardening of the adhesive.

[0006]

The present invention is constructed as described above, and after filling the container body with the moisture-curable polyurethane adhesive,
Place the moisture-proof plate on the moisture-curable polyurethane adhesive, and fill the joint between the inner wall surface of the container body and the outer peripheral edge of the moisture-proof plate with a predetermined amount of a sealing material composed of an ointment substance having a melting point of 35 ° C to 65 ° C. Apply and seal. When the adhesive is filled in the container at a temperature higher than the melting point of the sealing material, the sealing material slightly melts due to the subsequent contraction of the adhesive due to cooling and the sinking of the moisture-proof plate that follows it, and the inner wall of the container Along with the damp plate. As a result, the curing of the adhesive can be prevented, and the work efficiency can be improved because it is not necessary to remove the sealing material one by one when the adhesive is used.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a partially enlarged sectional view of an adhesive container 1 embodying the present invention, FIG. 2 is an enlarged sectional view of a portion X in FIG. 1, and 2 is a moisture-curable polyurethane adhesive W.
The container main body 3 filled with is a resin moistureproof plate placed on the adhesive W in the container main body 2, and fits on the inner wall surface 2a of the container main body 2 and slides along the inner wall surface 2a. It is formed so that it can be moved up and down.

At the center of the moisture-proof plate 3, there is formed a supply / discharge hole 4 for filling and discharging the adhesive W in the container body 2. The supply / discharge hole 4 is formed by the adhesive W. After the filling, the film is sealed with a moisture-proof film 5. Reference numeral 7 denotes a moisture-proof film which covers the upper end beat portion 2b of the container body 2, and 8 denotes a sealing lid which is attached to the container body 2 via a packing 9.

In the embodiment of the present invention, the melting point of 35 ° C. is formed at the joint between the inner wall surface 2a of the container body 2 filled with the adhesive W and the outer peripheral edge 3a of the moisture-proof plate 3 placed on the upper surface of the adhesive. ~
For example, the sealing material 10 made of an ointment-like substance at 65 ° C. is filled and applied in a width of 10 mm and a thickness of 5 mm. Further, as the ointment-like substance of the sealing material 10,
Petrolatum, petrolatum, wax, paraffin wax,
Since grease is used, this sealing material has low moisture permeability and can prevent the adhesive from hardening.

If the sealing material 10 having a melting point of less than 35 ° C. is used, the sealing material 10 is melted by the heat when the adhesive W is filled and flows, and the airtightness cannot be maintained. When the temperature is higher than 0 ° C., there is a problem that it cannot follow the case where the adhesive W cools and contracts (sinks) because it is viscous and hard. Therefore, the sealing material 10 made of an ointment substance having a melting point of 40 ° C. to 60 ° C. is suitable.

In particular, vaseline as the sealing material 10 has low moisture permeability and can prevent the curing of the adhesive. When the adhesive W is used, the sealing material 1
The work of removing 0 can be omitted, and work efficiency can be improved.

[0012]

According to the present invention, the melting point of 35 ° C to 65 ° C is formed at the joint between the inner wall surface of the container body filled with the adhesive as described above and the outer peripheral edge of the moistureproof plate placed on the upper surface of the adhesive. Since it is configured by filling and applying the sealing material composed of the ointment-like substance, the sealing material can follow the shrinkage due to the temperature drop of the filling adhesive, and therefore the work of removing the sealing material when using the adhesive can be omitted There is an effect that the curing of the agent can be prevented and the work efficiency can be significantly improved.
