Description

The present invention relates to a chemical vaporizer.

BACKGROUND ART Conventionally, there has been known a chemical liquid volatilizer that is used by inserting a rod-shaped volatilization body into a container containing a chemical liquid in such a manner that it protrudes from inside the container (see, for example, Patent Document 1). In this type of chemical volatilizer, the chemical liquid in the container is sucked up by the volatilization body and volatilized into the external space, thereby imparting the aromatic effect and other effects of the chemical liquid to the external space.

There are various types of volatilizers that suck up chemical solutions, but one example is one made of rattan that is widely used. The rattan volatilization body sucks up the chemical solution through the internal micropores by capillary action, and at this time, the chemical solution seeps out from the internal micropores to the outer surface. Since the volatilization body plays the role of sucking up the chemical liquid and volatilizing it into the external space, the chemical liquid often adheres to its outer surface during use. Note that this is not limited to rattan volatile bodies.

Japanese Patent Application Publication No. 2016-124603

FIG. 1 is an enlarged side sectional view of the vicinity of the opening at the top of the container of the chemical solution volatilizer described in Patent Document 1. As shown in the figure, the volatile material inserted into the container comes into contact with the peripheral edge surrounding the opening of the container. Therefore, the chemical liquid adhering to the outer surface of the volatilized body often accumulates near the contact point between the volatilized body and the peripheral edge, and then flows down along the outer wall surface of the container. In that case, the hands, walls, household goods, etc. of those who touched the container may become contaminated with the chemical solution.

An object of the present invention is to provide a chemical solution volatilizer that can prevent the chemical solution sucked up by the volatilization body from staining the outer wall surface of a container.

A chemical solution volatilizer according to a first aspect of the present invention includes a container having an opening at the top, a chemical solution accommodated in the container, and a rod-shaped volatilization body. The volatilization body is inserted into the container through the opening so that a portion of the volatilization body is exposed to the outside of the container in order to suck up the chemical solution from inside the container and volatilize it into an external space. The container includes a periphery surrounding and defining the opening. The peripheral portion has a first inner surface facing the opening and a second inner surface facing the opening. The second inner surface is located radially inside the opening than the first inner surface, and is located below the first inner surface. The first inner surface and the second inner surface are not smoothly continuous, and the volatile body inserted into the container contacts the second inner surface while maintaining a distance from the first inner surface.

A chemical solution volatilizer according to a second aspect of the present invention is the chemical solution volatilizer according to the first aspect, in which when the volatilization body is most inclined with respect to the vertical direction in the container, the volatilization body The first inner surface is in contact with the second inner surface and is located on the radially outer side of the opening with respect to the volatilization body.

A chemical solution volatilizer according to a third aspect of the present invention is the chemical solution volatilizer according to the first or second aspect, in which the first inner surface is arranged such that as it goes upward, it goes toward the outside in the radial direction of the opening. It forms an inclined surface.

The chemical volatilizer according to the fourth aspect of the present invention is the chemical volatilizer according to the third aspect, in which the first inner surface and the second inner surface are continuous.

A chemical volatilizer according to a fifth aspect of the present invention is a chemical volatilizer according to any one of the first to third aspects, wherein the first inner surface and the second inner surface form a step. .

A chemical solution volatilizer according to a sixth aspect of the present invention is a chemical solution volatilizer according to any one of the first to fifth aspects, in which the upper and lower portions between the upper end of the first inner surface and the upper end of the second inner surface are The length in the direction is 0.5 mm or more.

According to the present invention, the first inner surface and the second inner surface, both facing the opening, are formed at the peripheral edge defining the opening at the top of the container. The second inner surface is located inside and below the first inner surface. The volatilization body inserted into the container comes into contact with the second inner surface, but this second inner surface acts as a barrier and maintains a distance from the first inner surface. As a result, a space is formed between the volatilization body and the first inner surface, and the chemical liquid adhering to the outer surface of the volatilization body cannot reach the outer wall surface of the container. Thereby, it is possible to prevent the chemical liquid sucked up by the volatile body from staining the outer wall surface of the container.

DESCRIPTION OF EMBODIMENTS Hereinafter, chemical solution volatilizers according to some embodiments of the present invention will be described with reference to the drawings.

<1. First embodiment>
<1-1. Overall configuration of chemical vaporizer>
FIG. 2 shows an external view of the chemical vaporizer 1 according to the first embodiment. As shown in the figure, the chemical solution volatilization device 1 includes a container 2 in which a 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 at the top, and can accommodate the chemical liquid into the internal space S2 through the opening S1. Note that "upper" and "lower" in this specification are defined based on the usage state shown in FIG. 2, unless otherwise specified.

The rod-shaped volatilization body 3 is inserted into the container 2 in such a manner that it protrudes from inside the container 2 . That is, the volatilization body 3 has a sufficient length relative to the height of the container 2, and is arranged in such a manner that the lower end 3a is disposed inside the container 2 and the upper end 3b is exposed outside the container 2. It is inserted into the internal space S2 of the container 2 through the opening S1. Further, as will be described later, the volatilization body 3 has a structure capable of sucking up the chemical liquid against gravity by capillary action. As a result, the chemical solution in the container 2 can rise along the volatilization body 3 from the lower end 3a to the upper end 3b, and volatilize (natural evaporation) from the outer surface of the volatilization body 3 into the external space. Thereby, the chemical liquid is diffused into the space around the chemical liquid volatilizer 1.

The chemical solution used here is not particularly limited in type, but typically is a fragrance, a deodorant, an insect repellent, or a mixture thereof. Contains additives such as ingredients and colorants. The solvent contained in the drug solution is appropriately selected depending on the type of additive used, and can be a hydrophilic solvent, a lipophilic solvent, or a mixture thereof. When the medicinal solution contains a fragrance, it is preferable to contain at least a lipophilic solvent as a solvent in order to increase the fragrance 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. Further, the chemical solution may contain a solubilizing agent in order to solubilize functional components such as fragrances, deodorant components, insect repellent components, and colorants.

The shape and material of the volatilization body 3 are not particularly limited as long as the chemical liquid can be sucked up and volatilized to the outside. The volatile body 3 typically has an elongated, substantially cylindrical shape with micropores inside, and can be made of natural materials such as rattan, or synthetic resins such as polyethylene and polyacetal. You can also do it. The volatilization body 3 according to this embodiment has a cross-sectional shape shown in FIG. In this example, the volatile body 3 is made of polyethylene terephthalate and polyurethane, and has a large number of irregularly shaped micropores 31 inside. Further, this volatilization body 3 has an uneven outer surface, and a large number of grooves 32 are formed on the outer surface. These grooves 32 extend linearly along the axial direction of the volatilization body 3 from the lower end 3a to the upper end 3b. Further, these grooves 32 are arranged at approximately equal intervals along the circumferential direction of the volatilization body 3. Therefore, the chemical solution is sucked up not only through the micropores 31 but also along the grooves 32 due to capillary action. Therefore, a large amount of chemical liquid tends to adhere to the outer surface of the volatile body 3 of this embodiment.

<1-2. Container details>
The container 2 has a bottom portion 10 and a peripheral wall portion 20 that define an interior space S2. In the present embodiment, the bottom portion 10 has a shape in which a central portion 11 is slightly raised upwardly than an outer circumferential portion 12 thereof. Therefore, when the remaining amount of the chemical solution in the container 2 decreases, it accumulates around the periphery of the bottom portion 10. On the other hand, the lower end 3 a of the rod-shaped volatilization body 3 usually descends along the slope of the bottom 10 and is disposed at the periphery of the bottom 10 . Therefore, since the volatile body 3 and the chemical solution are configured to easily come into contact with each other, the chemical solution can be used up to the end.

The peripheral wall portion 20 has a cylindrical body portion 21, a shoulder portion 22 continuous to the upper end of the body portion 21, and a neck portion 23 (peripheral portion) continuous to the upper end of the shoulder portion 22. The neck portion 23 is a cylindrical portion surrounding the opening S1 at the top of the container 2, and is narrower than the body portion 21. Thereby, when the chemical solution volatilizer 1 falls, the shoulder portion 22 becomes a wall, making it difficult for the chemical solution to spill through the opening S1. In particular, in this embodiment, since the neck part 23 is arranged coaxially with the body part 21, the shoulder part 22 becomes a wall even if the chemical solution volatilizer 1 falls in any direction, and spilling of the chemical solution can be suppressed. 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 21 (the area of the cross section of the internal space S2), the amount of medicinal solution stored in the container 2 is reduced through the opening S1. Therefore, the amount of the chemical solution that evaporates naturally from inside 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 enough margin to prevent the volatilization body 3 from blocking the entire opening S1. In this case, the volatilization body 3 can be arranged at an angle within the container 2, and the aesthetic appearance can be improved. Moreover, from the viewpoint of further improving the aesthetic appearance, it is more preferable to arrange a plurality of volatilization bodies 3 so as to extend radially in various directions, as shown in FIG.

The material of the container 2 is not particularly limited, but may be made of glass or plastic, for example. From the viewpoint of making the remaining amount of the chemical liquid visible from the outside, it is preferable that the container 2 is formed to be transparent (including translucent).

3 is a plan view of the container 2, and FIG. 4 is an enlarged side sectional view of the vicinity of the neck portion 23 of the container 2 of the chemical solution volatilizer 1. As shown in these figures, in this embodiment, the upper part of the neck portion 23 forms an inclined surface on the radially inner side. Although this inclined surface is linear in side view in the example of FIG. 4, it may be curved in side view. Note that the radial direction in this specification is defined with the central axis of the opening S1 as a reference unless otherwise specified. Further, in this embodiment, the central axes of the opening S1, the internal space S2, the neck portion 23, the shoulder portion 22, and the body portion 21 are coaxial.

The neck portion 23 has a first inner surface 41 and a second inner surface 42 that both face the opening S1, and the first inner surface 41 and the second inner surface 42 are continuous with each other. However, the first inner surface 41 and the second inner surface 42 are not smoothly continuous at a point P2 that serves as a boundary between them. In other words, the first inner surface 41 and the second inner surface 42 each form a smooth continuous surface, but are bent at a point P2 that forms a boundary between them. Note that P1 represents a point at the upper end of the first inner surface 41, and P2 represents a point at the upper end of the second inner surface 42. In this embodiment, the point P2 is continuous with the lower end point of the first inner surface 41.

The second inner surface 42 is located radially inward than the first inner surface 41 and further below the first inner surface 41. In this embodiment, the first inner surface 41 forms an inclined surface that is inclined radially outward as it goes upward. The second inner surface 42 extends substantially parallel to the vertical direction.

FIG. 4 shows a state in which the volatilization body 3 inserted into the container 2 is most inclined with respect to the vertical direction (hereinafter referred to as the most inclined state). In the most tilted state, the lower end 3a of the volatilization body 3 contacts the outer peripheral portion 12 of the bottom portion 10 and also contacts the point P2 at the upper end of the second inner surface 42. At this time, the volatilization body 3 contacts the point P2 at the upper end of the second inner surface 42 while maintaining a distance from the first inner surface 41. That is, in the most inclined state, the second inner surface 42 separates the first inner surface 41 and the volatilization body 3, so the volatilization body 3 does not contact the first inner surface 41, and the volatilization body 3 and the first inner surface 41 are separated from each other. A space S3 is formed between them. Therefore, the first inner surface 41 in the most inclined state is arranged radially outward with respect to the volatilization body 3.

The angle between the axial direction of the volatile body 3 and the vertical direction is defined as θ1. Further, in a side view, the angle formed by the first inner surface 41 and the vertical direction is θ2. At this time, even in the most inclined state, θ2>θ1.

Further, the neck portion 23 has an upper surface 44 that is continuous to the point P1 at the upper end of the first inner surface 41, and further has an outer wall surface 45 that is continuous from the outermost point P4 of the upper surface 44 in the radial direction. The upper surface 44 and the outer wall surface 45 both face the external space of the container 2. The upper surface 44 is parallel to the horizontal direction, and the outer wall surface 45 faces the external space on the side of the container 2. As shown in FIG. 4, the upper part of the outer wall surface 45 according to this embodiment has a rounded shape that is convex outward in the radial direction when viewed from the side. Note that the upper surface 44 may be inclined with respect to the horizontal plane. Further, the upper surface 44 can be omitted.

With the above configuration, the chemical liquid adhering to the outer surface of the volatilization body 3 drips down along the outer surface, often at the contact point between the volatilization body 3 and the neck 23, or in this embodiment, at the point of contact between the volatilization body 3 and the second inner surface 42. may accumulate near point P2, which is the point of contact with. However, this chemical solution never reaches the outer wall surface 45 of the container 2. That is, since the first inner surface 41 extends in the vertical direction, it becomes an outer wall of the space S3, and the space S3 becomes a "pool of chemical solution." Therefore, the chemical solution does not reach the outer wall surface 45 beyond the first inner surface 41 and the upper surface 44. As a result, the chemical liquid is prevented from dripping along the outer wall surface 45 of the container 2, and the outer wall surface 45 is prevented from becoming contaminated with the chemical liquid. Furthermore, the hands of the person who touches the outer wall surface 45 of the container 2, the walls, household goods, etc., will not be soiled with the chemical solution. Further, in this embodiment, since the first inner surface 41, which also serves as the bottom surface of the space S3, is inclined downward as it goes radially inward, the chemical solution leaking into the space S3 is caused by gravity to the first inner surface 41. It is returned into the internal space S2 of the container 2 along the inner surface 41. Therefore, the risk of the chemical liquid staining the outer wall surface 45 is further reduced.

As described above, from the viewpoint of preventing the chemical solution from staining the outer wall surface 45, the length w1 in the vertical direction between the point P1 at the upper end of the first inner surface 41 and the point P2 at the upper end of the second inner surface 42 is It is preferable that 0.5 mm≦w1, more preferably 1.0 mm≦w1, and even more preferably 2.0 mm≦w1. Moreover, it is preferable that w1≦30 mm, more preferably that w1≦20 mm, and even more preferably that w1≦10 mm. Further, from the same viewpoint, the horizontal length w2 between the upper end point P1 of the first inner surface 41 and the upper end point P2 of the second inner surface 42 is preferably 1.0 mm≦w2; It is more preferable that .0 mm≦w2, and even more preferable that 3.0 mm≦w2. Moreover, it is preferable that w2≦45 mm, more preferably that w2≦30 mm, and even more preferably that w2≦15 mm.

Moreover, the greater the angle of the volatilization body 3 with respect to the horizontal plane, the more difficult it becomes for the chemical solution to drip from the volatilization body 3 into the space S3. Therefore, the angle θ3 (=90°−θ1) of the volatile body 3 with respect to the horizontal plane in the most inclined state is preferably 45°≦θ3, and more preferably 60°≦θ3.

<2. Second embodiment>
Next, a chemical solution volatilizer according to a second embodiment will be described with reference to FIGS. 6 and 7. Note that although the first embodiment and the second embodiment differ in the structure of the container, they have many points in common. Therefore, below, the differences between the two will be mainly explained, and common elements will be given the same reference numerals and explanations will be omitted.

FIG. 6 is a plan view of the container 102 according to this embodiment, and FIG. 7 is an enlarged side sectional view of the vicinity of the neck 23 of the container 102. As shown in these figures, in this embodiment, the upper part of the neck portion 23 forms a step D1 on the radially inner side.

The neck portion 23 has a first inner surface 41 and a second inner surface 42 that both face the opening S1, and further has a third inner surface 43 that also faces the opening S1 between these inner surfaces 41 and 42. . Although the first inner surface 41, the third inner surface 43, and the second inner surface 42 are continuous with each other in this order, they are not smoothly continuous at points P3 and P2, which are the boundaries between them. In other words, the first inner surface 41, the third inner surface 43, and the second inner surface 42 each form a smooth continuous surface, but are bent at points P3 and P2 that serve as mutual boundaries. Note that P3 represents a point at the upper end of the third inner surface 43. In this embodiment, the point P3 is continuous with the lower end point of the first inner surface 41, and the point P2 is continuous with the lower end point of the third inner surface 43.

The second inner surface 42 is located radially inward than the first inner surface 41 and further below the first inner surface 41. In this embodiment, the first inner surface 41 and the third inner surface 43 form an inclined surface that is inclined radially outward as it goes upward, and the inclined surface formed by the first inner surface 41 is , is more steeply inclined in the vertical direction than the inclined surface constituted by the third inner surface 43. The second inner surface 42 extends substantially parallel to the vertical direction. The first inner surface 41 and the second inner surface 42 form a step D1 with the third inner surface 43 in between. In addition, although the inclined surface formed by the first inner surface 41 and the third inner surface 43 is straight in a side view in the example of FIG. 7, it may be curved in a side view.

FIG. 7 shows a state in which the volatilization body 3 inserted into the container 102 is most inclined with respect to the vertical direction (hereinafter referred to as the most inclined state). In the most tilted state, the lower end 3a of the volatilization body 3 contacts the outer peripheral portion 12 of the bottom portion 10 and also contacts the point P2 at the upper end of the second inner surface 42. At this time, the volatilization body 3 contacts the point P2 at the upper end of the second inner surface 42 while maintaining a distance from the first inner surface 41. That is, in the most inclined state, the second inner surface 42 separates the first inner surface 41 and the volatilization body 3, so the volatilization body 3 does not contact the first inner surface 41, and the volatilization body 3 and the first inner surface 41 are separated from each other. A space S3 is formed between them. Therefore, the first inner surface 41 in the most inclined state is arranged radially outward with respect to the volatilization body 3.

Let θ1 be the angle that the axial direction of the volatile body 3 makes with the vertical direction, and let θ2 be the angle that the vertical direction makes with the straight line connecting points P1 and P2 (located at the same position in the circumferential direction of the opening S1). At this time, even in the most inclined state, θ2>θ1.

Further, the neck portion 23 has an upper surface 44 that is continuous to the point P1 at the upper end of the first inner surface 41, and further has an outer wall surface 45 that is continuous from the outermost point P4 of the upper surface 44 in the radial direction. The upper surface 44 and the outer wall surface 45 both face the external space of the container 102. The upper surface 44 is parallel to the horizontal direction, and the outer wall surface 45 faces the external space on the side of the container 102. As shown in FIG. 7, the upper part of the outer wall surface 45 according to this embodiment has a rounded shape that is convex outward in the radial direction when viewed from the side. Note that the upper surface 44 may be inclined with respect to the horizontal plane. Further, the upper surface 44 can be omitted.

With the above configuration, the chemical liquid adhering to the outer surface of the volatilization body 3 drips down along the outer surface, often at the contact point between the volatilization body 3 and the neck 23, or in this embodiment, at the point of contact between the volatilization body 3 and the second inner surface 42. may accumulate near point P2, which is the point of contact with. However, this chemical solution never reaches the outer wall surface 45 of the container 102. That is, since the first inner surface 41 extends in the vertical direction, it becomes an outer wall of the space S3, and the space S3 becomes a "pool of chemical solution." Therefore, the chemical solution does not reach the outer wall surface 45 beyond the first inner surface 41 and the upper surface 44. As a result, the chemical solution is prevented from dripping along the outer wall surface 45 of the container 102 and the outer wall surface 45 is prevented from becoming contaminated with the chemical solution. Furthermore, the hands of the person who touches the outer wall surface 45 of the container 102, the wall, household goods, etc., will not be soiled with the chemical solution. Furthermore, in the present embodiment, the third inner surface 43 constituting the bottom surface of the space S3 is inclined downwardly toward the inside in the radial direction, so that the chemical solution leaking into the space S3 is caused by gravity. 3 is returned into the internal space S2 of the container 102 along the inner surface 43. Note that this also applies to the first inner surface 41, which is inclined downwardly toward the inside in the radial direction. Therefore, the risk of the chemical liquid staining the outer wall surface 45 is further reduced.

As described above, from the viewpoint of preventing the chemical solution from staining the outer wall surface 45, the length w1 in the vertical direction between the point P1 at the upper end of the first inner surface 41 and the point P2 at the upper end of the second inner surface 42 is It is preferable that 0.5 mm≦w1, more preferably 1.0 mm≦w1, and even more preferably 2.0 mm≦w1. Moreover, it is preferable that w1≦30 mm, more preferably that w1≦20 mm, and even more preferably that w1≦10 mm. Further, from the same viewpoint, the horizontal length w2 between the upper end point P1 of the first inner surface 41 and the upper end point P2 of the second inner surface 42 is preferably 1.0 mm≦w2; It is more preferable that .0 mm≦w2, and even more preferable that 3.0 mm≦w2. Moreover, it is preferable that w2≦45 mm, more preferably that w2≦30 mm, and even more preferably that w2≦15 mm.

In the second embodiment, the first inner surface 41 of the neck portion 23 is inclined radially outward toward the top, but it may also extend parallel to the vertical direction, or as shown in FIG. It may be inclined so that it goes radially inward as it goes upward. The same applies to the third inner surface 43, which may extend parallel to the horizontal direction, or may be inclined upwardly and radially inwardly as shown in FIG. Further, in the first and second embodiments, the second inner surface 42 does not need to extend in the vertical direction, and may be inclined so as to be radially outward or inward as it goes upward.

<3-3>
As shown in FIG. 10, the upper part of the second inner surface 42 and the first inner surface 41 may be rounded. That is, the upper part of the second inner surface 42 and the first inner surface 41 may be curved in side view.

The container 2,102 of the above embodiment was entirely constructed in one piece. However, as shown in FIG. 11, the portion constituting the first inner surface 41 and the portion constituting the second inner surface 42 may be separate bodies. For example, the main body portion 41a including the first inner surface 41 may be made of glass, and the member 42a including the second inner surface 42 may be attached to the main body portion 41a. At this time, the member 42a including the second inner surface 42 may be made of an elastic material such as rubber or resin and may be of an insert type so that it can be easily attached to the main body portion 41a including the first inner surface 41.
