Abstract

PROBLEM TO BE SOLVED: To prevent the leakage of an internal liquid and the failure of a high-polymer thin film and a container body by providing a container with an escape means for allowing the gas in a container body to escape to the outside of the container body. SOLUTION: This container is composed of the blind container body 1 and a cap 2 for closing its opening. An vaporizing port 4 is formed at this cap 2. This vaporizing port 4 is closed with the liquid impermeable and gas permeable porous or non-porous high-polymer thin film 3 having perfume resistance and deodorant resistance. The fluid aromatic or deodorant 5, such as liquid, cream or gel, is housed in the container body 1. This aromatic or deodorant 5 comes into direct contact with the high-polymer thin film 3. Further, the bottom of the container body 1 is provided with an aperture 6 of about 1mm in diameter as the escape means. The internal pressure in the container body 1 escapes from the aperture 6 in this constitution, thereby making it possible to prevent the failure of the container, the failure of the high-polymer thin film and the liquid leakage by the rise of the internal pressure.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for fragrance or the like, and more particularly to a container for fragrance or the like in which an opening of a container body for containing the fragrance or deodorant is covered with a polymer thin film that is impermeable to liquid gas. It is a thing.

[0002]

2. Description of the Related Art Conventionally, a liquid non-permeable gas-permeable polymer thin film in which a liquid of an aromatic agent or a deodorant contained in a container is volatilized in the container and the volatilized gas is covered by a volatilization port of the container. There are known fragrance and deodorant products that can be volatilized to the outside through such fragrance and deodorant products.However, in such fragrance and deodorant products, only the low-boiling components that compose the fragrance are likely to volatilize initially. The scent of the ingredient is strong, but the strength of the scent is not long-lasting and the fragrance tends to change.
As shown in Japanese Patent Laid-Open No. 63-315058, each component constituting the above fragrance is obtained by directly contacting a liquid of an aromatic agent or a deodorant with a thin polymer film and allowing the liquid thin film to permeate and vaporize. Is evenly volatilized.

[0003]

However, in the above fragrance and deodorant products, since the gas in the container is in a sealed state, it is exposed to direct sunlight when it is used at a window at home or in a car. As a result, the temperature of the gas inside the container rises as the ambient temperature rises, causing a high pressure inside the container. There are drawbacks such as leakage and damage to the polymer thin film and the container body.

The present invention is designed to eliminate the above drawbacks.

[0005]

A container for an fragrance or the like according to the present invention comprises a bottomed container body for containing a fluid fragrance and a deodorant, and a liquid impermeable gas which covers the opening of the container body. It is composed of a permeable polymer thin film and an escape means provided in the container body for allowing the gas in the container body to escape to the outside of the container body.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a container of the present invention for containing an aromatic and a deodorant. 1 is a bottomed container body, 2 is a cap for closing the opening of the container body 1, and 3 is a volatilization formed on the cap 2. A liquid impermeable gas-permeable porous or non-porous polymer thin film 5 having a perfume resistance and a deodorant resistance that closes the mouth 4 is housed in the container body 1 and directly contacts the polymer thin film 3. A liquid fragrance or deodorant having fluidity such as cream, gel, etc.
In order to communicate the air chamber 7 inside with the outside, a relief means, for example, an opening 6 having a diameter of about 1 mm is provided at the bottom of the container body 1.

The opening 6 is not particularly limited as long as the internal pressure of the container can be released, and the opening 6 may be covered with a non-woven fabric or a polymer thin film, or the opening 6 may be covered with a valve. May be provided. In addition, a straw-like pipe that reaches the polymer thin film 3 through the air freshener or deodorant from the air chamber 7 in the container body 1 without providing the opening 6 or penetrates the polymer thin film 3 (see FIG. (Not shown) may be provided.

The polymer thin film 3 is fixed to the cap 2 by integrally molding the polymer thin film 3 with the cap 2, welding or adhering it to the volatilization port 4 of the cap 2, or sandwiching it with the container body 1 and the cap 2. You may keep it. In addition, without providing the cap 2 on the container body 1, the container body 1 is directly
It may be welded or adhered to the opening.

During transportation of the fragrance and deodorant products, in order to prevent liquid leakage, a packing for closing the opening of the container body 1 is sandwiched between the cap 2 and the container body 1,
And the volatilization port 4 of the cap 2 are closed by heat sealing.

Similarly, in order to prevent liquid leakage from the opening 6 during transportation, a protrusion for closing the opening 6 may be provided on the container body 1 so that the opening 6 appears when the protrusion is broken. Alternatively, the opening 6 may be closed with a screw, heat seal, adhesive seal, rubber, cork, or the like.

【Example】

Next, the present invention will be specifically described with reference to examples.

(Embodiment 1)

When a liquid fragrance was used as the content in the container, the heat resistance of the container of the present invention having the opening 6 and the conventional container having no opening were compared.

Earth Press / Green (trade name of liquid fragrance made by Carmate Co., Ltd.) was used as the liquid fragrance, and tetrafluoroethylene (film thickness 70 μm) was used as the polymer thin film 3.
m, caliber 0.1 μm), two 60 ml polypropylene containers were used as the containers, and the caps 2 of these two polypropylene containers were each equipped with a volatilization port 4 with a diameter of 22 mm.
The polymer thin film 3 is attached to the volatilization port 4, the cap 2 is placed under the container so that the fragrance and the polymer thin film 3 are in direct contact with each other, and one container has a diameter of 1 mm.
mm opening 6 is provided and the other container is not provided with opening 6
The two containers were left in a constant temperature bath at 95 ° C. for 4 hours, and the leakage of liquid from the polymer thin films in the two containers and the presence or absence of damage to the polymer thin film or the container body were visually determined.

The results are shown in Table 1.

[0018]

[Table 1]

As is clear from Table 1, in the container of the present invention having an opening, liquid leakage from the polymer thin film and damage to the container body were not observed, but the conventional container having no opening was used. In the container of No. 2, the internal pressure of the container increased at high temperature and liquid leaked from the polymer thin film, and almost all of the liquid in the container leaked to the outside.

(Example 2)

Next, when a creamy fragrance was stored as the contents in the container, the heat resistance of the container of the present invention having an opening and the heat resistance of a conventional container having no opening were compared.

Comparison was carried out under the same conditions as in Example 1 except that Sierra / Musk (trade name of creamy aromatic agent manufactured by Carmate Co., Ltd.) was used as the creamy aromatic agent.

Table 2 shows the results.

[0024]

[Table 2]

As is clear from Table 2, in the container of the present invention having an opening, neither leakage of liquid from the polymer thin film nor damage to the thin film and the container body was observed, but the conventional container having no opening was used. In the container, the polymer thin film was torn and could not withstand the increased internal pressure when the temperature was high, and most of the creamy fragrance in the container leaked to the outside.

[0026]

As described above, according to the present invention, since the opening 6 is provided in the container body 1 as described above, the internal pressure of the container can be released even if the internal pressure of the container rises due to the rise of the ambient temperature, and therefore the polymer thin film. There are great advantages such as no leakage of contents such as liquid from 3 and no damage to the polymer thin film or the container body.
