Description

The present invention relates to a chemical vaporizer.

BACKGROUND ART Conventionally, there is known a chemical solution volatilizer which is used by inserting a volatilizer for sucking a chemical solution into a container containing the chemical solution in such a manner as to project from the container. In this type of chemical solution volatilizer, typically, the chemical solution is sucked up by a volatilization body and volatilized into the external space, so that an effect such as an aroma effect of the chemical solution is imparted to the external space. Then, as the volatilizer for sucking up the chemical liquid, rattan is often used as shown in Patent Documents 1 and 2. The rattan has a minute cavity inside, and the drug solution can be sucked up through this cavity by a capillary phenomenon.

However, the rate at which rattan sucks up the drug solution is not necessarily high. That is, the chemical liquid sucked up through the inner cavity gradually leaches out to the outer surface, and then is vaporized from the outer surface. Therefore, when the volatilizer made of rattan is inserted into the container containing the drug solution at the start of use, it often takes a long time of several hours or more before the drug solution starts to fill the external space.

An object of the present invention is to provide a chemical solution volatilizer capable of sucking up a chemical solution and rapidly evaporating it naturally.

The chemical solution volatilizer according to the first aspect of the present invention includes a container and a volatilizer. The container has an opening at the top and stores a drug solution inside. The volatilizer is inserted into the container through the opening so that the lower end is disposed inside the container and the upper end is exposed to the outside of the container, and sucks the drug solution from the inside of the container. The volatilization body has an outer surface and a plurality of streak-like projections protruding from the outer surface and extending in the suction direction of the liquid medicine. A plurality of streak-shaped fine grooves extending in the suction direction are formed between the plurality of protrusions. The chemical liquid volatilizer is configured such that the chemical liquid sucked up along the large number of fine grooves by a capillary phenomenon spontaneously vaporizes into the external space.

A chemical liquid volatilizer according to a second aspect of the present invention is the chemical liquid volatilizer according to the first aspect, wherein the multiple protrusions include multiple first protrusions and multiple second protrusions. The first protrusion has a first protrusion height from the outer surface. The second protrusions are arranged so as to be scattered among the plurality of first protrusions, and have a second protrusion height higher than the first protrusion height from the outer surface.

A chemical liquid volatilizer according to a third aspect of the present invention is the chemical liquid volatilizer according to the first aspect or the second aspect, wherein the fine groove is closer to the external space side from the bottom of the outer surface side. It is configured to gradually widen.

A chemical liquid volatilizer according to a fourth aspect of the present invention is the chemical liquid volatilizer according to any one of the first to third aspects, wherein the volatilizer has a through hole extending in the vaporization body in the suction direction. .. The through hole has a cross-sectional area of a size that does not suck up the drug solution by a capillary phenomenon at least in a room temperature environment in a state where the volatilizer is inserted in the container.

A chemical liquid volatilizer according to a fifth aspect of the present invention is the chemical liquid volatilizer according to any of the first to fourth aspects, wherein the volatilizer is a rod-shaped member.

A chemical volatilizer according to a sixth aspect of the present invention is the chemical volatilizer according to the fifth aspect, wherein the volatilizer has a cross-sectional diameter of 1.5 mm or more and 4.0 mm or less.

A chemical liquid volatilizer according to an eighth aspect of the present invention is the chemical liquid volatilizer according to any of the first to seventh aspects, wherein the volatilizer is made of polyacetal resin.

According to the present invention, on the outer surface of the volatilization body, a large number of streak-shaped projections extending in the direction for sucking up the chemical liquid are provided, and thus a large number of fine grooves extending in the same direction are formed. As a result, when the volatilizer is inserted into the container, the drug solution is sucked up along the outer surface of the volatilizer due to the capillary phenomenon and quickly spontaneously evaporates from the outer surface. Thereby, a chemical solution volatilizer having an immediate effect is provided.

Hereinafter, a chemical solution volatilizer according to an embodiment of the present invention will be described with reference to the drawings.

<1. Overall configuration of chemical vaporizer>
FIG. 1 shows an external view of the chemical vaporizer 1 according to the present embodiment. As shown in the figure, the chemical solution volatilizer 1 includes a container 2 in which the chemical solution is stored, and a plurality of rod-shaped volatilization bodies 3 inserted into the container 2. The container 2 has an opening S1 in the upper part, and the chemical liquid can be stored in the internal space S2 through the opening S1. The rod-shaped volatilization body 3 has a sufficient length with respect to the height of the container 2, the lower end portion 3a is arranged inside the container 2, and the upper end portion 3b is opened in a manner exposed to the outside of the container 2. It is inserted into the internal space S2 of the container 2 via S1. Further, the volatilization body 3 has a structure capable of sucking up the chemical liquid against the gravity by a capillary phenomenon, as described later. As a result, the chemical liquid in the container 2 can rise up from the lower end portion 3a to the upper end portion 3b along the volatilization body 3, and spontaneously evaporates from the outer surface of the volatilization body 3 to the external space. As a result, the chemical liquid is diffused into the surrounding space where the chemical vaporizer 1 is placed.

The chemical solution used here is not particularly limited in its type, but is typically an aromatic, a deodorant or an insect repellent, or a mixture thereof, and depending on the purpose of use, a fragrance, a deodorant component, an insect repellent. Additives such as components and colorants are contained. The solvent contained in the drug solution is appropriately selected according to the type of additive used, and can be a hydrophilic solvent or a lipophilic solvent, or a mixture thereof. When the liquid medicine contains a fragrance, it is preferable to contain at least a lipophilic solvent as the solvent in order to enhance the scent intensity. As the hydrophilic solvent, for example, water or ethanol, or a mixture thereof can be used. As the lipophilic solvent, for example, glycol ether or isoparaffinic solvent, or a mixture thereof can be used. In addition, the chemical liquid may contain a solubilizer in order to solubilize functional components such as a fragrance, a deodorant component, an insect repellent component, and a coloring agent.

<2. Container>
The container 2 has a bottom portion 10 and a peripheral wall portion 20 that define an internal space S2. In the present embodiment, the bottom portion 10 has a shape in which the central portion 11 is slightly raised above the outer peripheral portion 12. Therefore, when the remaining amount of the chemical liquid in the container 2 decreases, the chemical liquid accumulates on the periphery of the bottom portion 10. On the other hand, the lower end portion 3 a of the rod-shaped volatilization body 3 usually descends along the inclination of the bottom portion 10 and is arranged at the peripheral edge of the bottom portion 10. Therefore, since the volatilization body 3 and the chemical solution are easily contacted with each other, the chemical solution can be used up to the end.

The peripheral wall portion 20 has a tubular body portion 21, a shoulder portion 22 that is continuous with the upper end of the body portion 21, and a neck portion 23 that is continuous with the shoulder portion 22. The neck portion 23 is a tubular portion that defines the opening S1 in the upper portion of the container 2, and is narrower than the body portion 21. As a result, when the chemical vaporizer 1 falls, the shoulder portion 22 serves as a wall, and the chemical liquid is less likely to spill through the opening S1. In particular, in the present embodiment, since the neck portion 23 is arranged coaxially with the body portion 21, the shoulder portion 22 becomes a wall even if the chemical solution volatilizer 1 falls down in any direction, and the spill of the chemical solution can be suppressed. In addition, since the cross-sectional area of the opening S1 is smaller than the cross-sectional area of the body portion 21 (the cross-sectional area of the internal space S2), the amount of the drug solution stored in the container 2 is through the opening S1. It is possible to suppress the amount of the chemical solution that spontaneously evaporates from the inside of the container 2.

As described above, the plurality of volatilization bodies 3 are inserted into the neck portion 23 that defines the opening S1. At this time, it is preferable that the volatilization body 3 be inserted into the opening S1 with a margin such that the entire volatilization body 3 does not block the entire opening S1. This is because in this case, the volatilization body 3 can be arranged in a tilted manner in the container 2, and the aesthetic appearance can be improved. Further, from the viewpoint of further improving the aesthetic appearance, as shown in FIG. 1, it is more preferable to arrange the plurality of volatilization bodies 3 so as to radially extend in various directions. In the example of FIG. 1, the volatilization body 3 is inserted into the container 2, and the upper end portion 3b is horizontally positioned outside the body portion 21 of the container 2 in a state where the lower end portion 3a is in contact with the peripheral edge of the bottom portion 10. As shown, it spreads widely and extends radially.

The material of the container 2 is not particularly limited, but may be glass or plastic, for example. From the viewpoint of allowing the remaining amount of the chemical liquid to be visually recognized from the outside, the container 2 is preferably formed transparent (including translucent).

<3. Volatilizer>
The volatilization body 3 is a slender rod-shaped member, and has a characteristic structure described later so that the chemical solution can be quickly sucked up. FIG. 2 is a cross-sectional view of the volatilization body 3 according to the present embodiment.

As shown in FIG. 2, the volatilization body 3 has a substantially cylindrical shape, and a large number of streak-like projections 40 projecting from the outer surface 30 are formed on the outer surface 30 of the cylinder. In addition, the volatilization body 3 which concerns on this embodiment matches the shape in arbitrary cross sections except the slight gap by a manufacturing error. The streak-like protrusion 40 extends in the direction of sucking up the chemical solution, that is, in the axial direction of the volatilization body 3, and particularly in the present embodiment, continuously extends from the lower end portion 3a to the upper end portion 3b. As a result, a large number of streak-shaped fine grooves S3 extending in the direction of sucking up the chemical liquid are formed between the large number of protrusions 40. The outer shape of the cross-section of the volatilization body 3 excluding the protrusion 40 may not be circular, and may be elliptical or polygonal such as triangular, quadrangular, and hexagonal. Yes, it can be star-shaped.

The fine groove S3 serves as a route for sucking the drug solution from the container 2 by a capillary phenomenon. Since these fine grooves S3 are formed on the outer surface 30 of the volatilization body 3, they are exposed to the external space except for the portion arranged inside the container 2. Therefore, when the volatilization body 3 is inserted into the container 2, the chemical liquid is sucked up along the outer surface 30 of the volatilization body 3 and quickly spontaneously evaporated from the outer surface 30 to the external space. As a result, immediate effect can be obtained for the effect of the drug solution. The term "quickly" as used herein means faster than when a conventional rattan is used. Therefore, here, it is assumed that it takes several seconds to several minutes mainly from the time when the volatilization body 3 is inserted into the container 2 until the chemical solution begins to fill the external space, but it is longer than this. It can be assumed that it takes time.

Further, in this embodiment, the protrusions 40 having different heights are formed on the outer surface 30. In the example of FIG. 2, protrusions 41 and 42 having two types of heights are alternately arranged along the circumferential direction of the outer surface 30. Therefore, in this embodiment, the high protrusions 42 are scattered between the short protrusions 41. As a result, the circumferential distance W1 between the adjacent low protrusions 41 and the high protrusions 42 is narrower than the circumferential distance W2 between the adjacent high protrusions 42, 42. In addition, in the present embodiment, the interval W1 is so narrow as to allow the drug solution to be quickly sucked up along the gap between the protrusions 41 and 42 by the capillary phenomenon under the normal temperature environment of 5 to 35°C. On the other hand, the distance W2 is so wide that the chemical liquid cannot be sucked up along the gap between the protrusions 42 and 42 under the same condition.

FIG. 3 is a partially enlarged cross-sectional view of the volatilization body 3. With the above configuration, the chemical liquid is sucked up between the protrusions 40 mainly through the space shown by the diagonal lines in FIG. In other words, among the spaces between the high protrusions 42, 42, the chemical solution mainly passes only in the recessed space up to the vicinity of the apex of the short protrusion 41, and the space close to the external space becomes the empty space S4. As a result, even if a hand, a wall, a curtain, or the like touches the protruding portion of the volatilization body 3 from the container 2, it is difficult for the chemical solution to adhere to such other objects, and the other objects are contaminated with the chemical solution. Can be prevented.

Further, the empty space S4 described above can also function as a return route for returning the excessively sucked up chemical liquid into the container 2. FIG. 4 is another partially enlarged cross-sectional view of the volatilization body 3 of FIG. 2, and is a cross-sectional view at the height position of the neck portion 23 of the container 2. As shown in the figure, although the high protrusion 42 may come into contact with the inner peripheral surface of the neck portion 23, the low protrusion 41 cannot come into contact therewith. Therefore, the volatilization body 3 and the inner peripheral surface of the neck portion 23 are At least an empty space S4 is formed between them. Therefore, the space S4 secures a route for the excessively sucked chemical liquid to return to the inside of the container 2 along the volatilization body 3, and the chemical liquid leaks out of the opening S1 along the outer surface of the neck portion 23. Can be prevented.

From the viewpoint of exhibiting the above effects, 0 mm<W1≦0.15 mm is preferable, and 0.15 mm<W2 is preferable.

Further, when the projection height of the shorter projection 41 from the outer surface 30 is H1, it is preferable that 0.01 mm≦H1. Further, when the protrusion height of the protrusion 42 from the outer surface 30 is H2, it is preferable that H1<H2, H2-H1≧0.15 mm, and more preferable that H2-H1≧0.2 mm. It is more preferable that H2-H1≧0.4 mm. Note that the longer the H2, the wider the empty space S4 can be secured. On the other hand, if the H2 is too long, the protrusion 42 is likely to be broken during transportation or the like. However, when the above numerical range is satisfied, it is possible to deal with the problem of damage during transportation while securing a large empty space S4.

When the cross-sectional diameter of the portion of the volatilization body 3 excluding the protrusions 40 (cross-sectional diameter of the outer surface 30) is L1, it is preferably 1.5 mm≦(L1+2H2), and 1.7 mm≦(L1+2H2). Is more preferable. Further, (L1+2H2)≦4.0 mm is preferable, (L1+2H2)≦3.5 mm is preferable, and (L1+2H2)≦2.5 mm is more preferable. When the numerical value range is satisfied, the volatilization body 3 has an appropriate thinness, and the aesthetic appearance can be enhanced. Further, in consideration of strength and aesthetics, it is most preferable that (L1+2H2)=about 2.0 mm. The cross-sectional diameter referred to here is the maximum width of the cross-section, and is the diameter when the outer shape of the cross-section is circular, and the length of the long axis when it is elliptical, If it is rectangular, it is the length of the longest diagonal. That is, the maximum width of the cross section is the maximum value of the length of the line segment that passes through the centroid of the cross section and is divided by the outer contour line of the cross section.

In the present embodiment, the protrusions 40 extend substantially radially from the center of the cross section when seen in a cross sectional view. Therefore, the fine groove S3 formed between the protrusions 40 gradually widens from the bottom portion on the outer surface 30 side toward the outer space side. As a result, in the fine groove S3, it becomes easier to hold the chemical liquid in the inner space, and it is possible to secure a sufficiently large empty space S4.

Inside the volatilization body 3, a minute through hole S5 extending in the axial direction is formed. However, it is preferable that the through-hole S5 has a cross-sectional area of a size that does not suck up the drug solution due to a capillary phenomenon under a normal temperature environment of 5 to 35°C. This is because, in this case, the volatilization body 3 cannot hold the chemical liquid in the through hole S5, so that the chemical liquid is not wasted. From this viewpoint, when the cross-sectional diameter of the through hole S5 is L2, it is preferable that L2>2.0 mm. The cross-sectional diameter here is defined as in the case of L1.

It is also possible to omit the through hole S5 in the volatilization body 3, that is, the volatilization body 3 may be a solid rod-shaped member. However, when the volatilization body 3 is manufactured by extrusion molding, a cylindrical mold is usually used. This mold has a cavity extending in the axial direction inside, and a large number of fine holes corresponding to the projections 40 extend in the axial direction on the inner wall of the cavity. Then, in order to precisely mold the volatilization body 3 using such a mold, a rod-shaped member is formed in the mold cavity with a certain distance from the inner wall of the cavity along the entire circumferential direction. It is preferable to insert a mold member. In this case, the volatilization body 3 molded from the cavity of the cylindrical mold can be efficiently cooled, and deformation and crushing of the core material portion and minute projections at the center of the volatilization body 3 can be prevented. Because you can. The through-hole S5 of the volatilization body 3 can be formed corresponding to the rod-shaped mold inserted in the cavity of the cylindrical mold when manufactured by such a method. As a result, the material of the volatilization body 3 can also be saved.

In the present embodiment, the volatilization body 3 is made of polyacetal resin. In this case, the volatilization body 3 having the fine structure as described above can be easily manufactured by extrusion molding or the like. Further, the volatile material 3 formed of the polyacetal resin is not substantially impregnated with the chemical solution inside. Therefore, the volatilization body 3 is not in a state of holding the chemical liquid excessively, and when the chemical liquid runs out from the container 2, the volatilization body 3 also immediately loses the chemical liquid held therein. Therefore, the end of use can be easily grasped. Further, since the chemical solution is not impregnated inside the volatilization body 3, the rate of sucking up the chemical solution is also increased. From the above viewpoints, the volatilizer 3 is preferably made of polyacetal resin, but is not limited to this, and may be made of another resin, for example, a material not impregnated with a chemical solution. Preferably.

<4. Modification>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the following changes are possible. Further, the gist of the following modified examples can be appropriately combined.

<4-1>
In the above embodiment, the volatilization body 3 has a rod shape, but may have a plate shape.

<4-2>
The cross-sectional shape of the volatilization body 3 is not limited to the above-mentioned shape, and may be, for example, a shape as shown in FIGS. 5 to 8. That is, as in the example of FIG. 5, a plurality of short protrusions may be formed between adjacent long protrusions. Further, as in the example of FIG. 5, the lengths of the protrusions may be three or more types instead of two types, or may be only one type as in the example of FIG. 6. Also in the case of the example in FIG. 6, by adjusting the interval between the adjacent protrusions, the fine grooves between the protrusions can function as a route for sucking up the chemical liquid. Further, the cross-sectional shape of the protrusion does not have to be linear, and may be Y-shaped as shown in FIGS. 7 and 8, for example.
