BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for containing substances such as liquids, and more particularly to a hard or soft container for containing substances that generate gas such as cosmetics, chemicals, paints and foods.

[0002]

2. Description of the Related Art Conventionally, various containers such as glass and plastic have been used as containers for storing liquid cosmetics and the like. For example, as a container for storing the decolorizing agent for cosmetics, a plastic container having a small-diameter opening is generally used above, and a cap or the like is attached so that the opening can be opened and closed. ..

[0003]

However, for example, when a gas-generating liquid such as a decolorizing agent is put in a container, it is necessary to leave the decoloring agent in the container for a long period of time or the environment such as ambient temperature. Depending on the conditions, the pressure of a large amount of generated gas may rise, and the plastic container may be deformed. Further, there is a problem that the cap cannot be removed when this deformation is large.

As a countermeasure against this, for example, it is possible to preliminarily form a hole for degassing in the cap, but in that case, another problem that the solution inside will flow out if the container falls down occurs. , Not practical. The present invention is
The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a container in which a substance in the container does not leak to the outside and can be suitably vented to prevent deformation.

In order to achieve this object, the invention of claim 1 is a container for containing a substance that generates gas, and a gas passage portion through which the gas passes is provided in a part of the container. A container is characterized in that a gas permeable material is disposed so as to cover the gas passage portion and prevent passage of the substance and permit passage of the gas.

Here, examples of the substance to be filled in the container include a liquid having a low viscosity, a creamy substance having a high viscosity, a gel substance, a powder, and a solid. For example, a liquid containing hydrogen peroxide solution. Alternatively, in addition to cosmetics such as two creamy hair dyes, permanent wave agents, decolorizing agents, etc., chemicals, foods, paints, etc. may be mentioned, but there is no particular limitation as long as they are substances that generate gas.

The container may be a hard container made of glass or plastic, or a tube made of soft plastic or rubber.
As the gas passage portion, for example, a hole having a hole diameter of 0.1 to 10 mm can be adopted, and the number thereof is not particularly limited. Further, for example, when using a cap, for example, a notch-shaped gas passage portion that communicates the inside of the container with the outside through a breathable material may be formed on the inner side where the screw of the cap is provided. There is no particular limitation as long as it is a configuration in which the inside of the container and the outside world are communicated with each other via a breathable material.

As the breathable material, biokiton-
α (trade name), GORE-TEX (trade name), Comfort Cross (trade name), Savina (trade name), etc. can be adopted, and the diameter of the fine holes through which the gas of the breathable material passes is, for example, 0.1 μm. It is a degree. The gas passage portion and the gas permeable material may be provided on the cap of the container as described later, but in addition to that, the gas passage portion and the gas permeable material are arranged and housed in the container body. An opening / closing hole for taking in and out the substance may be separately provided.

The invention according to claim 2 is characterized in that, in addition to the gas passage portion and the gas permeable material, a valve body for regulating passage of the substance by opening and closing is arranged inside the gas permeable material. The gist of the container according to item 1.

Here, as the valve body, for example, an elastic plastic plate made of a PP sheet or a PE sheet and having a thickness of 0.1 to 1 mm can be adopted, and the movable part of the valve body is the center of the plastic plate. Radial cuts are made from one point on the
A letter-shaped tongue can be adopted.

A third aspect of the present invention is the container according to the second aspect, characterized in that a spacer for securing a movable range of the valve body is arranged between the breathable material and the valve body. To do. Here, as the spacer, for example, an annular member made of a PP sheet or a PE sheet and having a thickness of 0.5 to 3 mm can be adopted.

Inside the valve body (inside the container),
Further, in order to prevent a large amount of liquid or the like from entering, a fibrous or mesh member may be arranged. Further, when the spacer or the valve body is used, the substance contained in the container is
It is preferable because it is possible to prevent the breathable material from reaching the breathable material at one time and damaging the breathable material, and to prevent the clogging of the breathable material, for example, when the content is a substance that easily causes clogging. ..

The invention according to claim 4 is summarized as the container according to any one of claims 1 to 3, wherein a part of the container having the gas passage portion is a cap of the container. Here, it is preferable that the gas passage portion is provided at the tip of the cap because the gas can easily pass therethrough and the contained substance does not easily flow out.

The invention according to claim 5 is summarized as the container according to any one of claims 1 to 4, characterized in that the breathable material is a material for inhibiting the passage of microorganisms. Here, the diameter of the fine pores that allow passage of the gas and prohibit passage of microorganisms is, for example, about 1.0 μm.

According to the invention of claim 1 having the above-mentioned constitution, the outflow of a substance such as a liquid in the container is blocked by a breathable material,
On the other hand, the gas generated from the substance passes through the breathable material. Then, the gas that has passed through the gas permeable material passes through the gas passage portion and flows out to the outside of the container. As a result, the gas generated from the substance inside the container is discharged to the outside of the container, so that the pressure inside the container is reduced and the deformation of the container can be prevented.

According to the second aspect of the present invention, since the valve body for adjusting the passage of the substance is arranged inside the breathable material (inside the container), the movement of the substance is restricted and the function of the breathable member is exerted. It helps. Further, for example, when the container falls down, it is possible to prevent the substance from reaching the breathable material at once and damaging the breathable material.

In the third aspect of the invention, since the spacer is arranged between the breathable material and the valve body, the valve body can be easily opened and closed. In the invention of claim 4, since the gas passage portion is formed in the cap of the container, the structure of the container is simplified as compared with the configuration in which the gas passage portion and the like are separately arranged.

According to the fifth aspect of the present invention, the breathable material inhibits the passage of microorganisms. Therefore, for example, when the liquid in the food is food or medicine, the influence of microorganisms can be eliminated.

[0019]

EXAMPLES In order to further clarify the constitution and operation of the present invention described above, preferred examples of the container of the present invention will be described below. FIG. 1 shows a container 1 as an example in a partially broken manner. The container 1 contains a liquid decolorizing agent such as cosmetics, and is composed of a container body 2 made of plastic and a cap 3 (shown in FIG. 2).

The lower portion of the container body 2 filled with liquid has a large diameter, and becomes thinner toward the upper portion, and a head portion 6 having a diameter smaller than that of the lower portion is formed at the upper portion. A screw thread 5 into which the cap 3 is screwed is formed in the head portion 6, and an opening portion 7 having an inner diameter of 19.5 mm is provided at the upper end of the head portion 6.

On the other hand, the upper portion 8 of the cap 3 projects outward in a substantially circular shape, and one gas passage hole 10 having an inner diameter of 3 mm for degassing is formed in the center of the upper portion 8. Further, a gas venting mechanism 15 is arranged above the inside of the cap 3 and attached with an adhesive so as to cover the inside of the gas passage hole 10, and the screw of the head portion 6 is further attached to the inner side surface of the cap 3. A screw thread 16 that is screwed with the thread 5 is formed.

As shown in FIG. 3, the degassing mechanism 15 is made of Gore-tex sheet (trade name) and has a thickness of 0.1.
5 mm: breathable member 20 having a diameter of 17 mm, thickness 2 mm made of PP film: annular spacer 22 having an inner diameter of 7 mm, P
A valve body 2 made of P film and having elasticity of 0.5 mm
4 and 4 are laminated and adhered.

The breathable member 20 has a large number of fine holes (inner diameter: 7.0 μm) formed therein, and allows passage of gas such as carbon dioxide, but water or alcohol. It is possible to prevent the passage of liquids of large molecules such as. In addition, the valve body 24 has a center point of 45
Notches 26 are formed that extend in eight directions at an angle of °, thereby forming eight tongue pieces 28 having a substantially V shape.

Next, the function of the container 1 of this embodiment constructed as described above will be described. As shown in FIG. 4, the container 1
When the liquid is filled with a liquid such as a gas volatile decolorizing agent, the gas is evaporated from the liquid. When this gas accumulates in the container 1, the pressure inside the container 1 gradually increases.
As a result, the gas pushes the tongue piece 28 of the valve body 24 upward in the drawing, so that the gas enters the space 22 a at the center of the spacer 22. Then, the gas in the space 22a passes through the gas permeable member 20, and then is discharged to the outside through the gas passage hole 10 in the upper portion 8 of the cap 3.

When the container 1 falls down, for example, the liquid may reach the valve body 28, but most of the liquid is blocked by the tongue piece 28 of the valve body 28 and enters the space 22a of the spacer 22. There is nothing to do. Further, even if liquid enters the space 22a in the spacer 22, the breathable member 2
Since 0 does not pass the liquid, the liquid does not spill out of the container 1.

That is, in the container 1 of the present embodiment, the gas generated from the liquid contained in the container 1 is much less
Before the gas pressure inside becomes high, it can be appropriately released to the outside through the gas passage hole 10 and the gas permeable member 20. Therefore, since the gas pressure in the container 1 is kept low, the deformation of the container 1 can be prevented.

Further, even if the container 1 falls over, for example, the liquid in the container 1 is prevented from flowing out of the container 1 because the liquid is prevented from flowing out by the breathable member 20 and the like. Moreover,
When the container 1 falls down, the valve body 24 prevents the liquid from reaching the breathable member 20 at once, so that the breathable member 20 can be prevented from being damaged.

The present invention is not limited to the above-described embodiments, and it is needless to say that the present invention can be implemented in various modes within the scope of the gist of the present invention. For example, as a degassing mechanism,
It is effective to use only the breathable member without using the spacer or the valve body.

Further, in the above-described embodiment, the gas passage hole or the like is provided in the cap, but the gas passage hole or the like is arranged in a part of the container, and a separate opening is provided for taking in and out the liquid, and the cap is covered. It may be configured to perform. Further, the gas passage holes formed in the cap may be arranged at five places as shown in FIG.

The container of the present invention can be applied not only to cosmetic containers such as decolorizing agents but also to various containers that generate gas such as chemicals, foods and paints. Moreover, since the passage of microorganisms can be prevented by adjusting the diameter of the pores of the breathable member, the use of such a breathable member is suitable for chemicals and foods.

[0031]

As described in detail above, according to the first aspect of the present invention, the outflow of the substance in the container is blocked by the breathable material, while the gas generated from the substance passes through the breathable material.
Therefore, the gas in the container is discharged to the outside of the container through the gas passage portion, so that the pressure in the container is reduced and the deformation of the container can be prevented.

According to the second aspect of the present invention, the movement of the substance is controlled by the valve body, which assists the breathable member.
It is possible to prevent the substance from reaching the breathable material at a stretch and damaging the breathable material when the container falls over. In the invention of claim 3, since the spacer is arranged between the breathable material and the valve body, the valve body can be easily opened and closed.

According to the invention of claim 4, since the gas passage portion is formed in the cap of the container, the structure of the container is simplified as compared with the structure in which the gas passage portion and the like are separately arranged. In the invention of claim 5, the breathable material inhibits the passage of microorganisms. Therefore, for example, in the case where the liquid inside is food or medicine, the influence of microorganisms can be eliminated.
