Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a container for storing fine powder medicines, cosmetics and the like, and more particularly to improvement of a container having a moisture-proof function.

<Prior art and problems to be solved> Conventionally, as a moisture-proof means in a container for storing a fine powder agent, a solid moisture-proofing agent such as silk gel is stored in a case having a large number of holes for ventilation, and the container mouth Some are attached to the part.

Although the conventional means can achieve the purpose in terms of the moisture-proof effect, it has the following problems.

That is, since the case containing the moisture-proofing agent is provided with a vent hole for moisture absorption, the fine powder agent in the container often enters the moisture-proofing agent case from the vent hole in the container distribution process. is there. Therefore, when the case containing the moisture-proofing agent is taken out of the container when using the fine powder agent, there are drawbacks such as the fine powder agent in the case spilling out from the ventilation hole to stain the surrounding area and make the user feel unclean. is there.

Therefore, the present invention is mainly intended to provide a moistureproof container for a fine powder agent which prevents the fine powder agent from entering through the hole even though there is a ventilation hole for absorbing moisture. By making the agent itself act as a valve for preventing intrusion of the fine powder agent, the structure is made extremely simple, which makes it possible to manufacture a moisture-proof container for fine powder agent that can be manufactured at a price almost the same as the conventional one. It is intended to be provided.

<Means for Solving the Problem> The configuration of the present invention for achieving the above object will be described below.
The present invention relates to a synthetic resin outer cylinder member 2 fitted in a mouth 1a of a container 1 for storing fine powder, a synthetic resin inner cylinder member 3 detachably fitted and connected to the outer cylinder member, The solid moistureproof agent 4 contained in the inner cylinder member 3. The outer cylinder member 2 has a cylindrical body 2b whose upper surface is closed by a top plate 2a and whose lower surface is open, and a flange portion 2c formed at the upper end of the body.
And a spring member 2d that is integrally formed from the lower surface of the top plate 2a and presses the upper surface of the desiccant. Further, the inner tubular member 3 has a tubular body portion 3a having an open upper surface.
And a bottom plate 3b that closes the lower surface of the body and a plurality of ventilation holes 3c formed in the bottom plate, and the ventilation holes 3c are closed by a moisture-proof agent stored in the inner tubular member 3. It is structured.

<Operation> In the above structure, as shown in FIG.
After the moisture-proofing agent 4 is put into the inner cylinder member 3, the inner cylinder member 3 is fitted into the outer cylinder member 2 from the lower end opening to connect them. As a result, the spring member 2d of the outer cylinder member 2 presses the upper surface of the moistureproof agent 4 and presses the moistureproof agent against the ventilation hole 3c to close it. Then, as shown in FIG. 2, the inner cylinder member 3 is attached to the mouth 1a of the container 1, and the outer cylinder member 2 is sealed with a metal outer cap 5 (or a synthetic resin outer cap). At this time, the flange portion 2c acts as a packing.

In this way, when the outer cap is closed, the ventilation hole 3c is elastically closed by the moistureproof agent 4 itself, so that the fine powder agent inside does not enter the inside of the outer cylinder member 2. Moreover, since the moisture preventive agent itself communicates with the inside of the container through the ventilation hole 3c, the moisture absorbing action is not impaired.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the present invention.
Synthetic resin outer cylinder member 2 attached to the mouth portion 1a of the container 1 for storing fine powder, synthetic resin inner cylinder member 3 detachably fitted and connected to the outer cylinder member, and the inner cylinder member 3 and a solid moistureproofing agent 4 such as silica gel.

The outer cylinder member 2 is integrally formed from a cylindrical body portion 2b whose upper surface is closed by a top plate 2a and whose lower surface is open, a flange portion 2c formed at the upper end of the body portion, and a lower surface of the top plate 2a. Tongue-shaped spring member that is pressed against the upper surface of the moisture-proofing agent
It consists of 2d. Further, the inner cylinder member 3 is composed of a cylindrical body portion 3a having an open upper surface, a bottom plate 3b closing the lower surface of the body portion, and a plurality of ventilation holes 3c formed in the bottom plate. The vent hole 3c is closed by the desiccant housed in.

The size, number, shape, etc. of the ventilation holes 3c may be set to the most preferable size depending on the required moisture absorption amount in the container, duration, etc.

In the above-described embodiment, the detachable fitting and connecting means for connecting the outer cylinder member 2 and the inner cylinder member 3 are the outer cylinder member 2 and the inner cylinder member 3, respectively.
This is achieved by fitting the ring-shaped fitting concave portion 2e and the convex portion 3d formed in the above. However, instead of this, a screwing means may be used.

Further, it is preferable that the ventilation hole 3b is formed in a downward trumpet shape as shown in the figure in order to enhance the moisture absorption effect.

Further, the spring member 2d may be formed by forming a part of the top plate 2a by elastically curving downward in a concave shape as shown in FIG. 4 instead of the tongue-like member. You can also

As shown in FIG. 3, when the moisture-proofing agent 4 has a small diameter, a guide tube 6 having a diameter corresponding to the size of the moisture-proofing agent can be formed on the top plate 2a of the outer cylinder member 2 to stabilize the moisture-proofing agent. Helps hold.

<Effect of device> Since the device of the present invention is configured as described above,
When the outer cap is closed, the vent hole 3c is closed by the moisture-proof agent 4 itself, and the vent hole 3c is opened by the spring member 2d.
Since it is elastically pressed against 3c to securely close it, it is possible to prevent the fine powder agent inside from invading the inside of the outer cylinder member 2 during the distribution process such as container transportation, which was described at the beginning. It is possible to prevent uncleanness and stains around the surroundings during use, and since the moistureproof agent itself communicates with the inside of the container through the ventilation hole 3c, it does not impair the hygroscopic effect. In addition, since the dehumidifying agent itself is operated as a valve of the ventilation hole 3c, it has an effect that it has a simple structure and can be manufactured at low cost.
