According to the conventional air freshener described above, a relatively large amount of the aromatic component is volatilized during the movement of the automobile, but the aromatic component continues to be volatilized even after the automobile is stopped. For this reason, the aromatic component is consumed even when the vehicle is not in use, such as when the vehicle is parked in a parking lot, and the service life of the air freshener is shortened accordingly.

The present invention has been made in view of the above points, and an object of the present invention is to provide a drug volatilizer capable of effectively volatilizing a drug and extending the service life.

One aspect of the chemical volatilization device of the present invention, first was the contacted layer containing microcapsules encapsulating agent having a volatility have a volatilization hole and having an inner surface, disposed movably accommodated contact member therein 1 A second container having a contact layer containing microcapsules containing a volatile drug on the inner surface and having a volatilization hole, and a contact body movably housed and arranged inside, the first container and the first container. It has a string-shaped member connected to a second container, and is used by connecting the string-shaped member to a vibration source.

According to one aspect of the present invention, it is possible to provide a drug volatilizer capable of effectively volatilizing a drug and extending the service life.

FIG. 1 is a perspective view showing a drug volatilizer according to an embodiment. FIG. 2 is a schematic view showing the structure of a main part of the drug volatilizer of FIG. FIG. 3 is a diagram showing an example of use of the drug volatilizer of FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the drug volatilizer 10 according to the embodiment has a structure in which two substantially spherical containers 2 and 4 having a hollow inside are connected by an annular rubber string 6 (string-shaped member). The rubber cord 6 does not necessarily have to be annular, and may be a single cord-like member, and may not necessarily be formed of a stretchable material.

As shown in FIG. 2, at least one contact body 1 is housed and arranged in one container 2. The number of contact bodies 1 can be arbitrarily set, the shape and size can be arbitrarily set, and the material and type can be arbitrarily set. In any case, it is sufficient that the contact body 1 moves in the container 2 and can collide with the inner surface of the container 2 when the container 2 is vibrated. In the present embodiment, only one type of a plurality of contact bodies 1 made of star-shaped resin having relatively many irregularities is housed and arranged in the container 2.

On the other hand, the inner surface of the container 2 is provided with a contact layer 3 formed by applying a slurry containing microcapsules (not shown) containing a volatile drug. The contact layer 3 is a layer that is contacted by the collision of the contact body 1, and the contact causes the microcapsules to break and release the drug. The contact layer 3 may be provided on the entire inner surface of the container 2, may be provided on a part of the inner surface of the container 2, and the position where the contact layer 3 is provided can be arbitrarily set. Further, the thickness of the contact layer 3 may be uniform or non-uniform. In the present embodiment, the contact layer 3 is provided on the entire inner surface of the container 2 with a uniform layer thickness.

Further, the inner surface of the container 2 may be provided with irregularities in order to increase the surface area thereof. In this case, the shape and height of the unevenness, the area where the unevenness is provided, and the like can be arbitrarily set. By increasing the surface area of the inner surface of the container 2, the amount of the slurry applied to the contact layer 3 can be increased, and more microcapsules can be held on the inner surface of the container 2. Further, a protrusion or a wall protruding inward from the inner surface of the container 2 may be provided, and the contact layer 3 may be provided on the surface thereof.

The other container 4 (another container) may or may not contain the contact body 1 in the same manner as the container 2. Further, the contact layer 3 may be provided on the inner surface of the container 4 as in the container 2, or the contact layer 3 may not be provided. The size and shape of the two containers 2 and 4 do not have to be the same. The container 4 does not need to be hollow inside. However, in this embodiment, the container 4 is formed to have the same structure as the container 2.

That is, the contact layer 3 formed by forming the two containers 2 and 4 into the same shape and applying a slurry containing microcapsules (not shown) containing volatile chemicals is also provided on the inner surface of the container 4. The contact body 1 was also housed and arranged in the container 4. Therefore, in the following description, the structure of one container 2 will be described in detail, and the detailed description of the structure of the other container 4 will be omitted by assigning the same reference numerals to the components that function in the same manner as the container 2. To do. The container 4 functions as a collision member (vibration imparting means) that gives vibration to the container 2 from the outside by colliding with the container 2 regardless of whether or not the contact body 1 is accommodated.

As shown in FIG. 3, the chemical volatilizer 10 having the above structure can be attached to the headrest 12 of a car, tied to a rearview mirror, hooked on a louver at an air conditioner outlet, or mounted on a rear seat. It can be used by connecting it to the assist grip above the. When connecting the chemical volatilizer 10 to, for example, the headrest 12, the rubber cord 6 is connected to one of the columns 12a of the headrest 12. Since the drug volatilizer 10 of the present embodiment vibrates the container 2 to break the microcapsules contained in the contact layer 3 and volatilize the drug, it can be attached to a moving body such as a car. Suitable for use.

Hereinafter, the structure of the drug volatilizer 10 will be described in more detail.
As shown in FIG. 2, the container 2 has a structure in which the openings of two substantially hemispherical transparent resin cases 2a and 2b are fitted to each other. One resin case 2a is provided with a plurality of circular volatilization holes 2c penetrating the resin case 2a (and the contact layer 3). On the other hand, the other resin case 2b is not provided with the volatilization hole 2c. The size of the volatilization hole 2c is designed so that the contact body 1 cannot pass through. The number and shape of the volatilization holes 2c can be set arbitrarily. The resin cases 2a and 2b do not have to be transparent, and for example, a pattern may be drawn on the surfaces of the resin cases 2a and 2b.

When the contact body 1 is housed in the container 2, first, the contact body 1 is housed in the resin case 2b having no volatilization hole 2c, and a sealing member (not shown) is attached to the opening of the resin case 2b to seal the container 2. To do. The opening of the resin case 2b is provided with a step portion for fitting the other resin case 2a, and a sealing member is attached to the edge of the opening. In this state, even if the resin case 2b is vibrated and the contact body 1 collides with the contact layer 3 to break the microcapsules, it is possible to prevent the chemicals from volatilizing to the outside.

Then, after that, the other resin case 2a is fitted with the resin case 2b so as to cover the sealing member that seals the opening. At this time, the contact body 1 is not housed in the resin case 2a. When fitting the two resin cases 2a and 2b, the edge of the opening of one resin case 2a may be overlapped with the step portion on the edge of the opening of the other resin case 2b and press-fitted. A screw may be provided on the step portion and both may be screwed together.

In this state, since all the contact bodies 1 are housed and arranged in the sealed space between the resin case 2b having no volatilization hole 2c and the seal member, the other resin is used unless the seal member is removed. There is no concern that the contact body 1 collides with the inner surface of the case 2a. Therefore, even though the resin case 2a has the volatilization holes 2c, the microcapsules of the contact layer 3 on the inner surface of the resin case 2a are broken and the drug is released in the state before the sealing member is removed. There is no need to worry about volatilization.

The sealing member is removed when the chemical volatilizer 10 is used. In this case, for example, a slit (not shown) for removing the seal member may be provided near the opening of one of the resin cases 2a (2b), and the seal member may be pulled out through the slit. Alternatively, the two resin cases 2a and 2b may be separated once, the seal member may be peeled off, and then the two resin cases 2a and 2b may be refitted. In any case, when the sealing member is removed from the container 2, the contact body 1 becomes movable in the container 2, and the drug can be volatilized through the plurality of volatilization holes 2c.

Alternatively, instead of providing the sealing member between the two resin cases 2a and 2b, a sealing member (not shown) covering the outer surface of the resin case 2a having the volatilization holes 2c may be attached. In this case, the other resin case 2b may also be provided with a volatilization hole 2c so that the entire outer surface of the container 2 is covered with a sealing member. In any case, the sealing member can be peeled off from the outer surface of the container 2 and is removed from the container 2 at the time of use. Alternatively, instead of attaching the sealing member to the surface of the container 2, an outer case (not shown) that covers the entire container 2 may be further provided to seal the entire container 2.

Alternatively, it is possible to more reliably prevent undesired volatilization of the drug without using the above-mentioned sealing member or outer case. That is, instead of accommodating the contact body 1 in the container 2 from the beginning, the resin cases 2a and 2b are separated at the time when the use of the drug volatilizer 10 is started, and the contact body 1 is accommodated in the container 2. You may. In the state where the contact body 1 is not housed and arranged in the container 2, even if vibration is applied to the container 2 from the outside, there is no member that collides with the contact layer 3 provided on the inner surface of the container 2, so that the contact layer 3 has. The contained microcapsules do not rupture and the drug does not start to volatilize. On the other hand, when vibration is applied from the outside while the contact body 1 is housed and arranged in the container 2, the contact body 1 collides with the contact layer 3 on the inner surface of the container 2, and the microcapsules are broken. Volatilization of the drug is started.

As shown in FIG. 2, a protrusion 7 having a mounting hole 7a for connecting the rubber cord 6 is provided on the edge of the opening of one of the resin cases 2a. The protrusion 7 may be projected from an arbitrary position on the outer surface of the container 2. Alternatively, a hole may be made in one of the resin cases 2a having a plurality of volatilization holes 2c, and the rubber cord 6 may be inserted and connected. In this case, the hole through which the rubber cord 6 passes also functions as a volatilization hole. FIG. 1 shows an example in which a hole is made in the resin case 2a of the container 2 and the rubber cord 6 is connected.

Hereinafter, the action of the drug volatilizer 10 having the above-mentioned structure will be described.
Since the chemical volatilizer 10 can be attached by connecting the rubber cord 6 to the object to be attached, the degree of freedom in selecting the installation location is high. For example, it can be mounted at a relatively high position in the car, such as a car headrest 12 or a rear-view mirror. The chemical volatilizer 10 is suitable for being attached to a moving body such as a car, but the mounting location is not limited to a moving body such as a car, and can be worn on the body of a human or animal, or vibrates such as a massage chair or a vacuum cleaner. It is also effective to attach it directly to the vibration source that generates. In this case, the rubber cord 6 tied to the vibration source, which is the object to be attached, functions as a vibration applying means for giving vibration to the container 2 (container 4). In this case, since it is possible that the two containers 2 and 4 collide with each other, the container 4 also functions as a vibration applying means for the container 2, and the container 2 also functions as a vibration applying means for the container 4. To do.

When the chemical volatilizer 10 is attached to a moving body such as a car, the vibration generated in the vehicle body when the car is running is transmitted to the chemical volatilizer 10, and the contact body 1 housed in the container 2 (container 4) is the container 2 (container 2). It collides with and comes into contact with the contact layer 3 provided on the inner surface of the container 4). As a result, the microcapsules contained in the contact layer 3 are broken, and the chemicals inside are released and volatilized in the air. That is, in the drug volatilization tool 10 of the present embodiment, vibration is applied from the outside and the contact body 1 comes into contact with the contact layer 3 to start volatilization of the drug, in other words, vibration from the outside is applied. Do not volatilize the drug in a stationary state. Therefore, for example, when the drug volatilizer 10 is attached to a car, the drug is actively volatilized during traveling, but the drug is not volatilized after a while after being parked in the parking lot.

As described above, according to the present embodiment, there is provided a drug volatilizer 10 capable of effectively volatilizing a drug when it is necessary to volatilize the drug and stopping volatilization naturally when the volatilization of the drug is not required. It is possible to suppress undesired volatilization of the drug, and it is possible to extend the service life of the drug volatilizer 10. For example, when the chemical volatilizer 10 is attached to a car, the chemical volatilizer 10 moves not only when the car is running but also due to vibration when opening and closing the door or the wind entering through the window, and the chemical volatilization starts. On the other hand, when the drug volatilizer 10 is stored in an unused state and started to be used, for example, several months later, the drug does not volatilize during storage, so even if the storage period before peeling off the seal member is long, It can be used with a normal service life.

Further, since the drug volatilizer 10 of the present embodiment has a structure in which a container 2 (container 4) having a contact layer 3 carrying a microcapsule containing a drug on the inner surface is connected by a rubber string 6, a headrest or a back is provided. It can be installed anywhere in the car, such as a mirror, and the installation location can be freely selected, improving convenience. Further, since the shapes and sizes of the containers 2 and 4 can be freely designed, the designability can be improved.

Although the present invention has been described above based on the embodiments, the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications and applications are possible within the scope of the gist of the present invention. is there.

For example, in the above-described embodiment, the case where the vibration applying means is the rubber string 6 connected to the container 2 has been described, but the present invention is not limited to this, and a spring can be connected to the container or the container can be swung as the vibration applying means. It may be attached to a holder.

Further, for example, in the above-described embodiment, the case where the contact layer 3 is formed by applying a slurry containing microcapsules to the inner surface of the container 2 has been described, but the present invention is not limited to this, and a volatile chemical is sealed therein. An inked product containing microcapsules may be printed on a sticker, and the sticker may be attached to the inner surface of the container 2 to form the contact layer 3.

Further, for example, at least a part of the contact body 1 may be impregnated with a slurry containing microcapsules containing a drug in a fragrance impregnated body. In this case, for example, viscopearl (trade name) which is a porous cellulose particle, paper, fluorite which is a porous calcium silicate particle, EVA (ethylene vinyl acetate copolymer) beads and the like can be used as the contact body 1. When the contact body 1 collides with and comes into contact with the contact layer 3 provided on the inner surface of the container 2 (container 4), the microcapsules contained in the contact body 1 in addition to the contact layer 3 are also ruptured, and the drug inside is charged. Can be released and volatilized in the air.

For example, the contact body 1 and the contact layer 3 may be provided with a property of changing color with time so that the service life of the drug volatilizer 10 can be visually recognized from the outside. In this case, apart from the contact body 1, a member whose color changes with time may be housed in the container 2 (or container 4). Alternatively, the surface of the contact body 1 may be colored to determine the service life based on the discoloration due to friction.
