Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid container composed of a body and a lid, and in particular, a lid container suitable for a film-forming fluid composed of an adhesive resin such as an adhesive or a paint and a volatile / evaporable solvent. It is about.

[0002]

2. Description of the Related Art Lid containers include one in which one of the lid and the body is externally fitted or internally fitted to the other, and one in which the lid and the body are externally fitted and internally fitted to each other. The latter has a higher sealing property than the former, and contains a solvent that volatilizes or evaporates like an organic solvent or water such as an adhesive or paint (hereinafter referred to as an evaporative solvent), and the solvent evaporates to form a film. It is optimal for containing a fluid having a film-forming property to form.

That is, a container (hereinafter, referred to as a double-sealed container) in which the body and the lid are fitted to each other outside and inside is bordered by a ridge protruding around the lid in a direction facing the mouth of the body. And
Around the mouth of the body is framed in a groove that fits into the ridge of the lid,
The cross-sections of the ridges and grooves are such that the left and right wall surfaces of the ridges and the left and right wall surfaces of the grooves are in close contact, and when the lid is closed, the inner wall surfaces and outer wall surfaces of the ridges and grooves are in close contact and the mouth It will be doubly sealed, and the evaporative solvent contained in the fluid inside the body will not evaporate and leak to the outside. Therefore, the double sealed container is widely used as a paint container (can).

[0004]

A fluid having a film-forming property, for example, a paint, is used by directly putting a brush in a container or transferring it from another container and storing it with the lid closed after the use. . In this case, in the double-sealed container, when the paint is used with a brush inserted or dispensed, the paint that has entered the groove around the mouth may be solidified during use and may fill the groove. In such a case, it becomes impossible to fit the ridges of the lid into the groove around the mouth, so that the lid cannot be closed even after the paint is used. Even if the lid ridge is pushed hard into the groove of the body to which the lump of paint that has evaporated and solidified by the evaporative solvent is closed and the lid is closed, the lump of the adhered remains in it. Since the evaporative solvent that is present evaporates completely and hardens strongly, the body and the lid are firmly adhered to each other, which makes it difficult to open the lid when the paint is reused.

[0005]

SUMMARY OF THE INVENTION Therefore, according to the present invention, when the paint is not accumulated in the groove that surrounds the mouth of the double-sealed container and the lid is once closed and the paint is used, the lid can be easily opened. The main purpose is to provide a double sealed container capable of

And 19 and 18 and 20. Therefore, the evaporative solvent contained in the film-forming fluid 24 inside the body 21 does not evaporate from the hole 22,
Therefore, by attaching the hole 22 to the groove 16, no inconvenience occurs.

Particularly, if the height h of the ridge 15 is set to be larger (higher) than the depth d of the groove 16, the ridge 1 is closed when the lid 12 is closed.
The bottom surface 27 of the groove 5 is in close contact with the bottom surface 23 of the groove 16, and the ridge 15
Since the hole 22 is sealed by the bottom surface 27 of the hole 22, the evaporation of the solvent from the hole 22 is completely stopped, and even if the container 13 is shaken during storage, the film-forming fluid 24 in the body 21 will not be exposed to the hole 22.
It is also prevented from seeping between the ridge 15 and the groove 16. In this way, the hole 22 is blocked by the bottom surface 27 of the ridge 15,
To stop evaporation of the solvent from the ridge 1 of the film-forming fluid 24
In order to eliminate the seepage between the 5 and the groove 16,
The finer the holes 22, the better, and if the diameter is about 1 to 3 mm, good results can be obtained.
