Abstract

PURPOSE:To prevent the generation of unpleasant environment in a room by installing an opening/closing valve made of shape memory resin which is provided with the shape restoration performance to a shape for closing a discharge port in a prescribed temperature region, onto the discharge port of a container. CONSTITUTION:A discharge port 7 is opened by bending the basic parts of plate parts 8a and 8b by pressing a pair of nearly semicircular plate parts 8a and 8b of an opening/closing valve body 8, inside from the outside the discharge port 7 by fingers. Then, the environmental temperature at the place where a container 1 is installed becomes over a prescribed value, and an excessively performed state is generated, and when the opening/closing valve 8 is bent in the restoration direction to a memorized shape, the discharge port 7 is closed. In the high temperature state, each quantity of volatilized gas and vapor which are supplied from a perfumer 2 increases rapidly, and the pressure in the container 1 increases. The opening/closing valve 8 is pressed by the increase of the internal pressure, and closely attached strongly onto the side wall inner surface of an upper side constitution body 4, and the discharge port 7 is closed. Therefore, the outside discharge of the volatile gas and vapor from the perfumer 2 is suspended automatically and perfectly, and the generation of the unpleasant environment in a room is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an aroma device that is placed inside a building, an automobile, or the like to emit fragrance.

<Conventional technology> In the past, volatile fragrances were stored in containers such as bottles, and when used, the release port was opened and left to emit the fragrance, and when it was not needed, the release was stopped by closing the cap. Air fresheners installed in such a way are known.

<Problems to be Solved by the Invention> However, when such conventional air fresheners are placed in a room such as a car, the room becomes hot (
For example, at temperatures above 36°C, the amount of volatilization and evaporation of the aromatic agent becomes extremely large, and a strong aroma is emitted.

As a result, a strong irritating odor is produced, causing a problem in that the interior of the room, which should be a comfortable environment, instead becomes an unpleasant environment.

Therefore, the present invention has been proposed in view of the above-mentioned conventional circumstances, and has a structure in which the outlet of the container is automatically closed by an on-off valve body made of shape memory resin in response to a rise in ambient temperature. The purpose is to solve the above conventional problems.

<Means for Solving the Problems> Therefore, the configuration of the aroma device of the present invention is as follows: “In an aroma device that stores a volatile liquid aroma agent and emits the aroma from an outlet formed in the peripheral wall, At the outlet of the container,
An air freshener characterized in that an on-off valve body made of a shape memory resin that has shape recovery properties is attached to close the discharge port in a predetermined temperature range. ”.

With this structure, when used at room temperature below a predetermined temperature, the valve body, which is in a hardened state in the form of a memory-shaped matrix, is forcibly deformed with fingers or the like to open the outlet of the container. , volatile gases and vapors from the fragrance stored inside are dissipated to the outside world.

Next, when the ambient temperature at the location where the container is installed reaches a predetermined temperature or higher, the valve body returns to its memorized shape matrix and comes into close contact with the discharge port to close it.

As a result, volatile gases and vapors from the fragrance are stopped from being released to the outside world.

If it is desired to use the aromatic device again, the valve body may be forcibly deformed to open the outlet of the container, as described above.

<Example> Next, embodiments of the present invention will be described based on the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a container of an aroma device which is capable of storing a volatile fragrance 2 therein, and is composed of lower and upper container structures 3 and 4. The lower structure 3 is formed into a cylindrical shape having a storage recess, and a female screw portion 5 is formed on the inner peripheral surface of the upper end. The upper structure 4 is formed into a cylindrical shape with two parts closed, and a male threaded part 6 that can be screwed into the female threaded part 5 is formed on the outer peripheral surface of the lower edge. The upper structure 4 has a cylindrical lower part and a substantially trapezoidal cross section in the upper part.

Approximately half-moon-shaped discharge lowers are formed on the upper trapezoidal peripheral wall of the container structure 4 so as to face each other.

The female threaded portion 5 of the image components 3 and 4 and the lower component 3,
By fitting the female threaded portion 6 of the upper structure 4,
Can be assembled.

In the container 1 having such a structure, an opening/closing opening/closing member made of a shape memory resin is provided inside the discharge lower and has shape recovery properties such that it bends in a direction that closes the discharge lower in a predetermined temperature range and returns to the parent phase. The valve body 8 is attached.

As shown in FIG. 3, the on-off valve body 8 consists of a rectangular fixed plate portion 8C and a pair of approximately half-moon shaped plate portions 8a and Ob. Fixedly attached to the inner surface of the ceiling wall.

The matrix memory shape of the on-off valve body 8 is a pair of substantially half-moon-shaped plate portions 8a relative to the fixed plate portion 8c.

8b is inclined at an obtuse angle greater than the inclination angle of the discharge lower, and when returning to this memorized shape, the plate portions 8a, 8b abut against the inner surface of the side wall of the container structure 4, closing the discharge lower 7. do.

When in use, the discharge lower is closed and the open/close valve body 8, which is in a cold hardened state, is forcibly deformed to open the discharge lower of the container.

That is, the pair of substantially half-moon-shaped plate portions 8a and/or the on-off valve body 8
Alternatively, the discharge lower can be opened by pressing 8b inward from the outside of the discharge lower with a finger to bend the bases of the plate parts 8a and 8b.

As a result, the volatile gas and vapor of the built-in fragrance agent are released from the release lower to the outside world.

After that, the ambient temperature at the location where the container 1 is installed is set to a predetermined temperature (
For example, when the fragrance is released excessively at temperatures above 36° C., the opening/closing valve body 8 bends in the direction of restoring its memorized shape, and the lower discharge lower is closed.

That is, the pair of substantially half-moon-shaped plate portions 8a and 8b form the container structure 4.
and closes the outlet I'7. In this high temperature state, volatile gas and steam rapidly increase from the aromatic agent 2, so that the pressure inside the container 1 increases. Due to this increase in internal pressure, the on-off valve body 8 is pressed, and the on-off valve body 8 is pressed against the upper structure 4.
The discharge lower is tightly sealed against the inner surface of the side wall.

As a result, the release of volatile gases and vapors from the fragrance 2 to the outside world is automatically and completely stopped.

If you want to use the aroma device 2 again when the ambient temperature has fallen, as described above, the on-off valve body 8 in the cold hardening state can be used again.
The discharge lower of the container 1 may be opened by forcibly deforming the container.

Next, another embodiment of the present invention will be described based on FIGS. 4 to 6.

In FIGS. 4 and 5, reference numeral 9 denotes an aroma device that stores a volatile aromatic agent 10 inside, and includes a bottle 12 having an opening 11 at the top, and a bottle 12 that can be freely attached to and detached from the opening 11. and a lid body 13. A male threaded portion 15 is formed on the outer peripheral surface of the neck portion 14 that forms the opening 11 . A female threaded portion 16 that can be screwed into the male threaded portion 15 is formed on the inner circumferential surface of the lower end of the lid 13 . Approximately elliptical fragrance outlets 1 are located at two opposing positions on the side circumference of the lid 13.
7 is formed.

Then, by fitting the male threaded portion 16 of the lid 13 into the male threaded portion 15 of the bottle 12, both are assembled.

In the container 9 having such a configuration, the discharge port 17 is made of a shape memory resin that is given a matrix shape so as to deform in a direction that closes the discharge port 17 in a predetermined temperature range, as in the previous embodiment. An on-off valve body 18 is installed.

As shown in FIG. 6, the on-off valve body 18 is formed in a cylindrical shape and is disposed along the inner circumferential wall of the lid body 13. As shown in FIG. In this case, the on-off valve body 18 is connected to the end face of the opening 11 of the bottle 12 and the lid body 13.
is placed between the inner surface of the upper wall of the

The memorized shape of the on-off valve body 18 is a cylindrical shape with a diameter slightly larger than the inner diameter of the lid body 13.

That is, the cylindrical outer circumferential surface is in contact with the inner circumferential surface of the lid 13 to close the discharge port 17 .

Even in an air freshener with such a configuration, when in use, the outlet 1
7 is closed to forcibly deform the on-off valve body 18 which is in a cold hardened state, and the discharge port 17 is opened.

That is, the outlet 17 is opened by pressing the outer periphery of the opening/closing valve body 18 facing the outlet 17 inward from the outside with a finger so that the outer periphery can be heard.

As a result, the volatile gas and vapor of the built-in air freshener 0 are gradually released from the release port 17 to the outside world.

Next, the ambient temperature at the location where the container 9 is installed reaches a predetermined temperature (
For example, when the temperature exceeds 36° C., the outer periphery of the on-off valve body 18 recovers from its concave state to its memorized shape and closes tightly to the discharge port 17.

Also in this embodiment, the opening/closing valve body 18 is pushed by the increase in internal pressure within the container 9, and the discharge port 17 is sealed even more tightly.

As a result, the release of volatile gas and vapor from the aromatic agent 10 to the outside world is stopped.

After that, if you want to use the aroma device again when the ambient temperature drops, as described above, the outer circumference of the open/close valve body 1B that is in the cold hardened state is forcibly formed into four layers, and the outlet 17 of the container 9 is All you have to do is open it.

According to the air freshener having such a configuration, when the air freshener is placed inside a car or the like, when the indoor temperature reaches a high temperature (e.g., 36° C. or higher), the on-off valve body 8.18 deforms and the discharge lower, 1
7 is automatically closed, so even if the amount of volatilization or evaporation of the air freshener 2.10 becomes extremely large and a strong fragrance transpires, the fragrance will not be released into the room without the need to close the valve. ,
It is possible to prevent the room from becoming an uncomfortable environment.

Note that the present invention is not limited to the shape of the container, the shape and formation position of the outlet, and the shape of the valve body in the above embodiments.

<Effects of the Invention> As explained above, according to the present invention, when the ambient temperature rises, the outlet of the container is automatically closed by the valve body made of shape memory resin, and the sealing force is also strengthened according to the internal pressure of the container. Because of this structure, even if the amount of volatilization or evaporation of the air freshener becomes extremely large and a strong fragrance is emitted, it is possible to prevent the room from becoming an unpleasant environment and improve usability. It has the usefulness that can be achieved.
