The solid adhesive used in the present invention always contains the above-mentioned adhesive component, a gelling agent, a solvent, the above-mentioned various waxes and / or the above-mentioned various substances for forming the evaporation suppressing film. It can be manufactured by stirring and mixing according to the method, and allowing it to cool and solidify. Also, the shape of the solid adhesive is
It is set according to the shape of the solid adhesive container,
For example, if the cross-sectional shape of the solid adhesive container is a rectangular shape such as a rectangle or a square, a triangular shape such as an equilateral triangle or an isosceles triangle, or a rectangular shape such as a pentagonal shape or a hexagonal shape, the shape of the solid adhesive container conforms to each container shape. Thus, the shape of each solid adhesive can be determined.

In the solid adhesive container of the present invention, as described above, the solid adhesive container has a cross-sectional shape other than a circular shape, and at least the solid adhesive contained in the solid adhesive container is An adhesive component, a gelling agent, and a solvent are contained, and the solid adhesive contains any one of the components (1) to (4) to provide excellent long-term stability over time and to improve coating performance. It becomes what can be made excellent. That is, in the solid adhesive container having a cross section other than a circular cross-section, the solid adhesive container is apt to be deformed due to localization,
Although it may be difficult to ensure the sealing performance even by applying a lid with a cap, in the present invention, even if the securing of the sealing performance by the container body and the cap is insufficient, For example, even if the application portion (upper surface portion) of the solid adhesive is in contact with the outside air in the air for a long time, the solid adhesive contains one of the above-mentioned components, thereby being excellent. It exhibits excellent coating performance together with stability over time.

The function of this action mechanism differs slightly depending on the form of the solid adhesive described above. That is, in the above, at least an adhesive component, a gelling agent, and, while containing a solvent, when using a solid adhesive containing waxes having the above various solubility characteristics, the solid adhesive of the solid adhesive Even if the application part is left in the air or the sealability of the application part of the solid adhesive container containing the solid adhesive is insufficient, the wax contained in the solid adhesive is dried. As a result, a very brittle film (evaporation suppressing film) is formed on the application portion, and this film prevents evaporation of a solvent which is a volatile component contained in the solid adhesive component and prevents the film from forming at the time of application. The film is broken by the application pressure, so that the application is possible. In addition, although the formation of the film slightly varies depending on the application amount, the wax contained in the solid adhesive is present again in the required amount in the application part. So next When section is exposed to the atmosphere secondary, dried to form a new film on the coating unit surface, the film formation → applying → film formation → coating ...... shows a effect repeated many times. Accordingly, even if the application portion of the solid adhesive is left in the air for a long time, or even if the sealing property of the application portion of the solid adhesive container containing the solid glue is insufficient, the application portion is not applied. The surface is hard to dry and solidify, and has excellent coating performance.

In the case where a solid adhesive containing at least an adhesive component, a gelling agent and a solvent and containing a substance for forming an evaporation suppressing film is used, the application of the solid adhesive is performed. Even if the part is left in the air or the sealability of the application part of the solid adhesive container containing the solid adhesive is insufficient, the evaporation suppressing film contained in the solid adhesive is formed. When the substance takes in moisture in the air and / or the solid adhesive, specifically, the solvent or the like evaporates from the surface of the solid adhesive. Moisture and / or
Or, the moisture in the atmosphere with high affinity with the solvent dissolves into the solid adhesive, and the composition changes near the surface, causing the applied part (surface)
A very brittle film [a liquid crystal surface film (evaporation suppressing film) is formed, and this film prevents evaporation of a solvent which is a volatile component contained in the solid adhesive component, and
The film is broken by the application pressure at the time of application to enable application, and the formation of the film is slightly different depending on the amount of application, but forms an evaporation suppressing film contained in the solid adhesive. The necessary amount of the substance to be applied is present again in the application section, so that when the application section is next exposed to the air or the like, the moisture in the air and / or the solid adhesive is taken in the same manner as described above, and a new surface is applied to the application section surface. A film is formed, and this film formation → application → film formation → application... Exhibits an effect repeated many times. Thereby, even if the application part of the solid adhesive is left in the air for a long time, or the sealing property of the application part of the solid adhesive container containing the solid adhesive is insufficient, The surface of the applied portion is hardly dried and solidified, and has excellent application performance. In addition, when the solid adhesive contains water, the effect is exhibited even when the humidity is low. However, if the amount is too large, the adhesiveness is reduced due to a decrease in dryness and the like. .

Further, the above-mentioned solid adhesive containing at least an adhesive component, a gelling agent, and a solvent, and containing various waxes having the above-mentioned properties and substances for forming the above-mentioned various evaporation suppressing films. In the case of using the solid adhesive, even if the application part of the solid adhesive is left in the air or the sealing property of the application part of the solid adhesive container containing the solid adhesive is insufficient, the solid adhesive is used. A very brittle composite film (evaporation suppression) is applied to the coating part by drying the waxes contained in the agent and by the substance forming the evaporation suppression film taking in moisture in the air and / or the solid adhesive. (Composite film). The mode of formation of this composite film is as follows: i) The film of wax alone is slightly incomplete, and it is considered that the film has fine pores, and the evaporation suppressing substance fills the fine pores (film). Or ii) by the incorporation of an evaporation inhibitor having a similar structure to the waxes (by the evaporation inhibitor acting as a substance having a fluidity-lowering effect), thereby forming a crystal of the film. It is presumed that it depends on whether the structure is formed as the structure becomes finer (dense). Evaporation of a solvent or the like which is a volatile component contained in the solid adhesive component is further prevented by the composite coating as compared with the solid adhesive of the above-described form, and the composite coating is broken by the application pressure at the time of application, The coating can be performed, and the formation of the composite film is slightly different depending on the amount of the coating. However, the waxes contained in the solid adhesive and the substance forming the evaporation suppressing film are re-used only in necessary amounts. Since it is in the application area, the next time the application area is exposed to the atmosphere, a new composite film is formed on the surface of the application area, and this composite film formation → application → composite film formation → application ...
Indicates an effect repeated many times. This allows
Even if the application part of the solid adhesive is left in the air for a long time, or if the application part of the solid adhesive container containing the solid adhesive is not sufficiently sealed, Is hard to dry and solidify, and has more excellent coating performance.

In the solid adhesive container of the present invention configured as described above, even if the solid adhesive container has a cross-sectional shape other than a circular shape, the solid adhesive container accommodated in the container can be used. Among them, by containing any of the above-mentioned components, as described above, since the surface of the solid adhesive applied portion is hardly hardened, excellent temporal stability and application performance are realized. .

It can be implemented. For example, as the use of the solid adhesive, for example, the adhesive component, the type of the gelling agent and the solvent, the composition and the like are appropriately changed according to the use of the solid adhesive for office use, the solid adhesive for socks, and the like.
