Description

  The present invention relates to a chemical vaporizer.

  2. Description of the Related Art Conventionally, there has been known a chemical liquid volatilizer that is used by inserting a volatilizing body for sucking up a chemical liquid into a container in which the chemical liquid is accommodated in such a manner as to protrude from the container. In this type of chemical liquid volatilizer, typically, the chemical liquid is sucked up by the volatilizer and volatilized in the external space, so that an effect such as an aromatic effect of the chemical liquid is imparted to the external space. And as a volatilization body which sucks up a chemical | medical solution, as shown in patent documents 1, 2, ratan is often used. Rattan has a fine cavity inside, and the drug solution can be sucked up by capillary action through this cavity.

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

  An object of this invention is to provide the chemical | medical-solution volatilizer which can suck up a chemical | medical solution and can spontaneously evaporate quickly.

The volatilization body has an outer surface and a plurality of streak-like protrusions protruding from the outer surface and extending in the direction of sucking up the chemical solution. A large number of streak-like fine grooves extending in the sucking direction are formed between the numerous protrusions. The chemical liquid volatilizer is configured such that the chemical liquid sucked up by capillary action along the numerous fine grooves is naturally evaporated to the external space.

  The 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 a large number of first protrusions and a large number of second protrusions. The first protrusion has a first protrusion height from the outer surface. The second protrusions are disposed so as to be scattered between the first protrusions and have a second protrusion height higher than the first protrusion height from the outer surface.

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

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

<1. Overall configuration of chemical volatilizer>
In FIG. 1, the external view of the chemical vaporizer 1 which concerns on this embodiment is shown. As shown in FIG. 1, the chemical liquid volatilizer 1 includes a container 2 in which a chemical liquid is stored and a plurality of rod-shaped volatilizers 3 inserted into the container 2. The container 2 has an opening S1 in the upper part, and the chemical solution can be accommodated 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, and is opened in such a manner that the lower end 3 a is disposed in the container 2 and the upper end 3 b is exposed to the outside of the container 2. It is inserted into the internal space S2 of the container 2 via S1. Moreover, the volatilization body 3 has a structure which can suck up a chemical | medical solution against gravity by capillary action so that it may mention later. As a result, the chemical solution in the container 2 can rise 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. Thereby, a chemical | medical solution is spread | diffused to the surrounding space where the chemical | medical solution volatilizer 1 was placed.

  The type of the chemical solution used here is not particularly limited, but is typically a fragrance, a deodorant or an insect repellent, or a mixture thereof. Depending on the purpose of use, a fragrance, a deodorant component, an insect repellent Additives such as ingredients and colorants are contained. The solvent contained in the chemical 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 a chemical | medical solution contains a fragrance | flavor, in order to raise the fragrance intensity | strength, it is preferable to contain a lipophilic solvent at least as a solvent. As the hydrophilic solvent, for example, water, 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. Moreover, in order to solubilize functional components, such as a fragrance | flavor, a deodorizing component, an insect repellent component, and a coloring agent, the chemical | medical solution may contain the solubilizer.

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

  The peripheral wall portion 20 includes a cylindrical trunk portion 21, a shoulder portion 22 that continues to the upper end of the trunk portion 21, and a neck portion 23 that continues to the shoulder portion 22. The neck portion 23 is a cylindrical portion that defines the opening S <b> 1 at the top of the container 2, and is narrower than the trunk portion 21. Thereby, the shoulder 22 becomes a wall when the chemical liquid volatilizer 1 falls, and the chemical liquid is less likely to spill through the opening S1. In particular, in this embodiment, since the neck part 23 is arrange | positioned coaxially with the trunk | drum 21, no matter which direction the chemical | medical solution volatilizer 1 falls, the shoulder part 22 becomes a wall and can suppress the spilling of a chemical | medical solution. In addition, since the area of the cross section of the opening S1 is smaller than the area of the cross section of the body portion 21 (the area of the cross section of the internal space S2), the amount of the chemical solution stored in the container 2 is reduced via the opening S1. Thus, the amount of the chemical liquid that spontaneously evaporates from the container 2 can be suppressed.

  As described above, a plurality of volatilization bodies 3 are inserted into the neck portion 23 that defines the opening S1. At this time, it is preferable to insert the volatilization body 3 into the opening S1 with a margin that the entire opening S1 is not blocked by the volatilization body 3. In this case, it is because the volatilization body 3 can be inclined and arrange | positioned in the container 2, and aesthetics can be improved. Further, from the viewpoint of further improving the aesthetic appearance, as shown in FIG. 1, it is more preferable to dispose a plurality of volatilization bodies 3 so as to extend radially in various directions. In the example of FIG. 1, the volatilizer 3 is inserted into the container 2, and the upper end 3 b is positioned outside the trunk 21 of the container 2 in the horizontal direction in a state where the lower end 3 a is in contact with the peripheral edge of the bottom 10. As shown in FIG.

  Although the material of the container 2 is not specifically limited, For example, it can be made from glass or plastics. From the viewpoint of making the remaining amount of the chemical liquid visible from the outside, the container 2 is preferably formed to be transparent (including translucent).

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

  As shown in FIG. 2, the volatilization body 3 has a substantially cylindrical shape, and a plurality of streak-like projections 40 protruding 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 corresponds in the shape in arbitrary cross sections except for the slight shift by a manufacturing error. The streak-like projections 40 extend along the direction of sucking up the chemical solution, that is, the axial direction of the volatilizing body 3, and in particular in the present embodiment, continuously extend from the lower end portion 3 a to the upper end portion 3 b. As a result, a large number of streak-shaped fine grooves S3 extending in the direction of sucking up the chemical solution are formed between the large number of projections 40. In addition, the external shape of the part except the protrusion 40 of the cross section of the volatilization body 3 does not need to be circular, and can also be made into an ellipse, and can also be made into polygons, such as a triangle, a rectangle, and a hexagon. It can be a star or the like.

  The fine groove S3 becomes a route for sucking up the chemical solution from the container 2 by capillary action. Since these fine grooves S3 are formed on the outer surface 30 of the volatilization body 3, the fine grooves S3 are exposed to the external space except for the portion arranged in the container 2. Therefore, when the volatilization body 3 is inserted into the container 2, the chemical solution is sucked up along the outer surface 30 of the volatilization body 3, and quickly spontaneously evaporates from the outer surface 30 to the external space. Thereby, immediate effect is obtained in the effect of the chemical solution. Here, “rapidly” means that it is faster than when conventional rattan is used. Therefore, it is assumed here that it takes mainly several seconds to several minutes from the time when the volatilizer 3 is inserted into the container 2 until the chemical solution begins to fill the external space. It can also be assumed that time is required.

  In the present embodiment, the outer surface 30 is formed with protrusions 40 having different heights. In the example of FIG. 2, two kinds of heights 41 and 42 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 interval W1 between the adjacent low protrusions 41 and the high protrusions 42 is narrower than the circumferential interval W2 between the adjacent high protrusions 42 and 42. Moreover, in this embodiment, the space | interval W1 is so narrow that a chemical | medical solution can be rapidly sucked up by a capillary phenomenon along the clearance gap between the processus | protrusions 41 and 42 in a normal temperature environment of 5-35 degreeC. On the other hand, the interval W2 is so wide that the chemical solution cannot be sucked up under the same condition along the gap between the protrusions 42 and 42.

  FIG. 3 is a partially enlarged cross-sectional view of the volatilizing body 3. With the above configuration, the chemical solution is sucked up between the protrusions 40 mainly through the space shown by the oblique lines in FIG. In other words, of the space between the high protrusions 42, 42, the chemical solution passes mainly through the deep 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 S 4. As a result, even if a hand, a wall, a curtain, or the like touches the protruding portion of the volatilizer 3 from the container 2, the chemical solution is difficult to adhere to such other objects, and the other objects are contaminated by the chemical solution. Can be prevented.

  Moreover, the above-mentioned empty space S4 can also function as a return route for returning the excessively sucked chemical liquid into the container 2. FIG. 4 is another partial 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 23 of the container 2. As shown in the figure, since the high protrusion 42 may contact the inner peripheral surface of the neck portion 23 but the low protrusion 41 cannot contact, the volatilization body 3 and the inner peripheral surface of the neck portion 23 At least a free space S4 is formed between them. Accordingly, the space S4 secures a route for the excessively sucked chemical liquid to return to the container 2 along the volatilizer 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 exerting the above effects, 0 mm <W1 ≦ 0.15 mm is preferable, and 0.15 mm <W2 is preferable.

  Moreover, it is preferable that 0.01 mm ≦ H1 when the protrusion height from the outer surface 30 of the shorter protrusion 41 is H1. Further, when the protrusion height of the protrusion 42 from the outer surface 30 is H2, H1 <H2, H2−H1 ≧ 0.15 mm is preferable, and H2−H1 ≧ 0.2 mm is more preferable. Preferably, H2−H1 ≧ 0.4 mm. Note that the longer the H2, the larger 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. However, in the case where the above numerical range is satisfied, it is possible to deal with a problem of breakage during transportation or the like while ensuring a wide empty space S4.

  Moreover, it is preferable that it is 1.5 mm <= (L1 + 2H2), when the cross-sectional diameter of the part except the processus | protrusion 40 (cross-sectional diameter of the outer surface 30) of the volatilization body 3 is set to 1.5 mm <= (L1 + 2H2). It is more preferable that 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 satisfy | filling this numerical range, the volatilization body 3 has moderate thinness, and can improve aesthetics. Further, considering the strength and aesthetics comprehensively, it is most preferable that (L1 + 2H2) = about 2.0 mm. Note that the cross-sectional diameter here is the maximum width of the cross section, the diameter is when the outer shape of the cross section is circular, and the length of the major axis when it is oval, In the case of a square shape, it is the length of the longest diagonal line. That is, the maximum width of the cross section is a line segment that passes through the centroid of the cross section and is the maximum value of the length of the line segment that is divided by the external contour line of the cross section.

  In the present embodiment, the protrusions 40 extend substantially radially from the center of the cross section when viewed in cross section. Therefore, the fine groove S3 formed between the protrusions 40 is gradually widened from the bottom on the outer surface 30 side toward the outer space side. As a result, in the fine groove S3, the chemical solution can be easily held in the inner space, and a sufficiently wide empty space S4 can be secured.

  Inside the volatilization body 3, a fine 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 chemical solution by capillary action in a normal temperature environment of 5 to 35 ° C. In this case, since the volatilizer 3 cannot hold the chemical solution in the through-hole S5, the chemical solution is not wasted. From this viewpoint, it is preferable that L2> 2.0 mm when the cross-sectional diameter of the through-hole S5 is L2. The cross-sectional diameter here is defined in the same manner as in the case of L1.

  In addition, in the volatilization body 3, through-hole S5 is abbreviate | omitted, ie, the volatilization body 3 can also be used as a solid rod-shaped member. However, when manufacturing the volatilization body 3 by extrusion molding, a cylindrical metal mold is usually used. This mold is a mold having a cavity extending in the axial direction inside, and a large number of micropores corresponding to the protrusions 40 extending along the axial direction on the inner wall of the cavity. And in order to shape | mold the volatilization body 3 precisely using such a metal mold | die, in the state where it spaced apart from the inner wall of the cavity over the perimeter direction in the cavity of a metal mold | die, rod-shaped. It is preferable to insert a mold member. In this case, it is possible to efficiently cool the volatilized body 3 that is also molded from the cavity of the cylindrical mold, and to prevent deformation and crushing of the core material portion and the fine protrusions at the center of the volatilized body 3. Because it can. The through-hole S5 of the volatilization body 3 can be formed corresponding to a rod-shaped mold inserted into a cavity of a cylindrical mold when manufactured by such a method. As a result, the material of the volatilizer 3 can be saved.

  In this embodiment, the volatilizer 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. Moreover, the volatilization body 3 formed from a polyacetal resin is not substantially impregnated with a chemical solution. Therefore, the volatilization body 3 does not enter a state in which the chemical liquid is excessively retained, and when the chemical liquid is exhausted from the container 2, the chemical liquid that is also retained by the volatilization body 3 is immediately lost. Therefore, the end of use can be easily grasped. Further, since the chemical solution is not impregnated inside the volatilizing body 3, the suction speed of the chemical solution is also increased. From the above viewpoint, the volatilizer 3 is preferably made of a polyacetal resin, but is not limited thereto, and can be made of, for example, another resin, which is not particularly impregnated with a chemical solution. Preferably.

<4. Modification>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning. For example, the following changes can be made. In addition, the gist of the following modifications can be combined as appropriate.

<4-1>
In the said embodiment, although the volatilization body 3 was made into rod shape, plate shape may be sufficient.

<4-2>
The cross-sectional shape of the volatilization body 3 is not limited to that described above, and can be, for example, a shape as shown in FIGS. That is, as in the example of FIG. 5, a plurality of short protrusions may be formed between adjacent long protrusions. In addition, the length of the protrusion may be three or more types as in the example of FIG. 5, or may be only one type as in the example of FIG. In the case of the example of FIG. 6 as well, by adjusting the interval between adjacent protrusions, the fine groove between the protrusions can be made to function as a chemical liquid suction route. Further, the cross-sectional shape of the protrusion does not have to be linear, and for example, it can be Y-shaped as shown in FIGS.
