Description

The present invention relates to a chemical volatilizer.

BACKGROUND ART Conventionally, a chemical liquid volatilizer is known that is used by inserting a rod-shaped volatilizing body into a container containing a chemical liquid in such a manner as to protrude from the container (see, for example, Patent Document 1). In this type of chemical liquid volatilizer, the chemical liquid in the container is sucked up by the volatilizer and volatilized into the external space, thereby imparting an effect such as an aromatic effect of the chemical liquid to the external space.

There are various types of volatilization bodies for sucking up chemical liquids, and one example is one made of rattan. The volatilization body made of rattan sucks up the chemical liquid by capillary phenomenon through the internal micropores, and at this time, the chemical liquid seeps out from the internal micropores to the outer surface. Since the volatilization body plays a role of sucking up the chemical liquid and volatilizing it to the external space, in many cases, the chemical liquid adheres to its outer surface during use. In addition, this is not limited to the volatilization body made from rattan.

FIG. 1 is a side sectional view enlarging the vicinity of the upper opening of the container of the chemical volatilizer described in Patent Document 1. FIG. As shown in the figure, the volatilization body 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 volatilization body often accumulates in the vicinity of the contact point between the volatilization body and the peripheral portion, and then flows down along the outer wall surface of the container. In that case, the hands, walls, household goods, etc. of a person who touches the container may become soiled with the chemical solution.

An object of the present invention is to provide a chemical liquid volatilizer capable of preventing the chemical liquid sucked up by the volatilization body from staining the outer wall surface of the container.

A chemical 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 volatilizer. The volatilization body is inserted into the container through the opening so that a part of the volatilization body is exposed to the outside of the container in order to suck up the chemical liquid from the inside of the container and volatilize it into an external space. The container includes a rim 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 positioned radially inward of the opening relative to the first inner surface and positioned below the first inner surface. The first inner surface and the second inner surface are not smoothly continuous, and the volatilization body inserted into the container contacts the second inner surface while maintaining a distance from the first inner surface.

A chemical volatilizer according to a second aspect of the present invention is the chemical volatilizer according to the first aspect, wherein when the volatilization body is most inclined with respect to the vertical direction in the container, the volatilization body 2 inner surface, and the first inner surface is located radially outside of the opening with respect to the volatilization body.

A chemical volatilizer according to a third aspect of the present invention is the chemical volatilizer according to the first aspect or the second aspect, wherein the first inner surface is directed outward in the radial direction of the opening as it goes upward. It forms an inclined surface.

A chemical volatilizer according to a fourth aspect of the present invention is the chemical volatilizer according to the third aspect, wherein the first inner surface and the second inner surface are continuous.

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

A chemical volatilizer according to a sixth aspect of the present invention is the chemical volatilizer according to any one of the first aspect to the fifth aspect, wherein the upper end of the first inner surface and the upper end of the second inner surface The length of the direction is 0.5 mm or more.

According to the invention, the periphery defining the opening of the upper portion of the container is formed with a first inner surface and a second inner surface which both face the opening. The second inner surface is positioned inside and below the first inner surface. And although the volatilization body inserted in the container contacts the 2nd inner surface, this 2nd inner surface becomes a barrier and keeps 1st inner surface and distance. As a result, a space is formed between the volatilization body and the first inner surface, and the chemical solution adhering to the outer surface of the volatilization body cannot reach the outer wall surface of the container. As a result, it is possible to prevent the chemical liquid sucked up by the volatilization body from staining the outer wall surface of the container.

Hereinafter, chemical 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 volatilizer>
FIG. 2 shows an external view of the chemical volatilizer 1 according to the first embodiment. As shown in the figure, the chemical volatilizer 1 includes a container 2 containing a chemical and a plurality of rod-like volatilizers 3 inserted into the container 2 . The container 2 has an opening S1 in its upper portion, through which the liquid medicine can be accommodated in the internal space S2. It should be noted that "upper" and "lower" as used in this specification are defined based on the state of use shown in FIG. 2 unless otherwise specified.

The rod-shaped volatilization body 3 is inserted into the container 2 in such a manner as to protrude from the inside of the container 2 . That is, the volatilization body 3 has a sufficient length with respect to the height of the container 2, the lower end 3a is arranged in 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. In addition, the volatilization body 3 has a structure capable of sucking up the chemical against gravity by capillary action, as will be described later. As a result, the chemical liquid in the container 2 can rise from the lower end portion 3a to the upper end portion 3b along the volatilization body 3, and volatilize (naturally transpire) from the outer surface of the volatilization body 3 to the external space. As a result, the chemical is diffused into the surrounding space where the chemical volatilizer 1 is placed.

The chemicals used here are not particularly limited in type, but are typically aromatics, deodorants, insect repellents, or mixtures thereof. Ingredients, additives such as colorants are included. The solvent contained in the drug solution is appropriately selected according to the type of additive used, and may be a hydrophilic solvent, a lipophilic solvent, or a mixture thereof. When the liquid medicine contains a fragrance, it preferably contains at least a lipophilic solvent as a solvent in order to increase the intensity of the fragrance. As hydrophilic solvent, for example, water or ethanol or a mixture thereof can be used. As lipophilic solvents, for example, glycol ethers or isoparaffinic solvents, or mixtures thereof can be used. In addition, the chemical liquid may contain a solubilizer to solubilize functional ingredients such as fragrances, deodorant ingredients, insect repellent ingredients, and coloring agents.

The shape and material of the volatilization body 3 are not particularly limited as long as the liquid chemical can be sucked up and volatilized to the outside. The volatilization body 3 typically has an elongated, substantially cylindrical shape with micropores inside, and can be made of natural materials such as rattan, or can be made of synthetic resins such as polyethylene and polyacetal. can also The volatilization body 3 according to this embodiment has a cross-sectional shape shown in FIG. In this example, the volatilization body 3 is made of polyethylene terephthalate and polyurethane, and has a large number of irregular micropores 31 inside. The 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 along the axial direction of the volatilization body 3 from the lower end 3a to the upper end 3b. Moreover, these groove|channels 32 are arrange|positioned at substantially equal intervals along the circumferential direction of the volatilization body 3. As shown in FIG. Therefore, the chemical liquid is sucked up not only along the fine holes 31 but also along the grooves 32 by capillary action. Therefore, a large amount of the chemical liquid is likely to adhere to the outer surface of the volatilization body 3 of the present embodiment.

<1-2. Container details>
The container 2 has a bottom portion 10 and a peripheral wall portion 20 that define an internal space S2. In this embodiment, the bottom portion 10 has a shape in which the central portion 11 is slightly raised above the outer peripheral portion 12 . Therefore, the liquid medicine in the container 2 accumulates on the periphery of the bottom part 10 when the remaining amount of the liquid medicine becomes small. On the other hand, the lower end portion 3 a of the rod-shaped volatilization body 3 normally descends along the slope 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 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 continuing to the upper end of the body portion 21 , and a neck portion 23 (peripheral portion) continuing to the upper end of the shoulder portion 22 . The neck portion 23 is a cylindrical portion that surrounds the opening S1 at the top of the container 2 and is narrower than the body portion 21 . As a result, when the chemical volatilizer 1 falls over, the shoulder portion 22 acts as a wall, making it difficult for the chemical to spill through the opening S1. In particular, in this embodiment, since the neck portion 23 is arranged coaxially with the body portion 21, the shoulder portion 22 serves as a wall even if the chemical volatilizer 1 is overturned in any direction, and spillage 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 accommodated in the container 2 is reduced through the opening S1. Therefore, the amount of the chemical solution that naturally 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 to the extent that the entire opening S1 is not blocked by the volatilization body 3 . In this case, the volatilization body 3 can be inclined and arranged in the container 2, and the appearance can be improved. Moreover, from the viewpoint of further improving the appearance, as shown in FIG. 2, it is more preferable to arrange a plurality of volatilization bodies 3 so as to extend radially in various directions.

Although the material of the container 2 is not particularly limited, it can be made of glass or plastic, for example. The container 2 is preferably formed transparent (including translucent) from the viewpoint of making the remaining amount of the chemical liquid visible from the outside.

FIG. 3 is a plan view of the container 2, and FIG. 4 is an enlarged side cross-sectional view of the vicinity of the neck portion 23 of the container 2 of the chemical volatilizer 1. As shown in FIG. As shown in these figures, in this embodiment, the upper portion of the neck portion 23 forms an inclined surface on the radially inner side. Although this inclined surface is linear in a side view in the example of FIG. 4, it may be curved in a side view. It should be noted that the radial direction in this specification is defined with reference to the central axis of the opening S1 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 the point P2 that is the 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 the point P2 that is the boundary between them. P1 represents the point of the upper end of the first inner surface 41 and P2 represents the point of 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 of the first inner surface 41 and further located 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 inclined state, the volatilization body 3 contacts the upper end point P2 of the 2nd inner surface 42 while the lower end part 3a contacts the outer peripheral part 12 of the bottom part 10. As shown in FIG. At this time, the volatilization body 3 contacts the point P2 of the upper end of the 2nd inner surface 42, maintaining the 1st inner surface 41 and distance. That is, in the most inclined state, since the second inner surface 42 separates the first inner surface 41 and the volatilization body 3, the volatilization body 3 does not contact the first inner surface 41, and the volatilization body 3 and the first inner surface 41 A space S3 is formed therebetween. Therefore, the first inner surface 41 in the most inclined state is arranged radially outward with respect to the volatilization body 3 .

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

Further, the neck portion 23 has an upper surface 44 continuing from the upper end point P1 of the first inner surface 41, and further has an outer wall surface 45 continuing from the radially outermost point P4 of the upper surface 44. As shown in FIG. Both the upper surface 44 and the outer wall surface 45 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 portion of the outer wall surface 45 according to the present embodiment has a rounded shape that protrudes radially outward in a side view. Note that the upper surface 44 may be inclined with respect to the horizontal plane. Also, the upper surface 44 can be omitted.

From the above configuration, the chemical liquid adhering to the outer surface of the volatilization body 3 drips along the outer surface, often the contact between the volatilization body 3 and the neck 23, in this embodiment, the volatilization body 3 and the second inner surface 42 may accumulate in the vicinity of point P2, which is the point of contact with . However, this chemical does not reach the outer wall surface 45 of the container 2 . That is, since the first inner surface 41 extends in the vertical direction, it becomes the outer wall of the space S3, and the space S3 becomes the "medical solution pool". Therefore, the chemical does not reach the outer wall surface 45 beyond the first inner surface 41 and the upper surface 44 . As a result, it is possible to prevent the liquid medicine from dripping along the outer wall surface 45 of the container 2 and staining the outer wall surface 45 with the liquid medicine. As a result, a person's hand, walls, household goods, etc., which come in contact with the outer wall surface 45 of the container 2, are not stained with the chemical solution. In addition, in the present embodiment, the first inner surface 41, which is also the bottom surface of the space S3, is inclined downward as it goes radially inward. It is returned along the inner surface 41 into the internal space S2 of the container 2 . Therefore, the possibility that the chemical liquid stains 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 vertical length w1 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 0.5 mm≦w1 is preferred, 1.0 mm≦w1 is more preferred, and 2.0 mm≦w1 is further preferred. Moreover, w1 ≤ 30 mm is preferable, w1 ≤ 20 mm is more preferable, and w1 ≤ 10 mm is further preferable. From the same point of view, the horizontal length w2 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 preferably 1.0 mm≦w2. It is more preferable that 0 mm≦w2, and even more preferably 3.0 mm≦w2. Moreover, w2 ≤ 45 mm is preferable, w2 ≤ 30 mm is more preferable, and w2 ≤ 15 mm is even more preferable.

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

<2. Second Embodiment>
Next, a chemical volatilizer according to a second embodiment will be described with reference to FIGS. 6 and 7. FIG. Although the first embodiment and the second embodiment differ in the structure of the container, they are common in many respects. Therefore, in the following, the differences between the two will be mainly described, and the common elements will be given the same reference numerals and the description thereof 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 portion 23 of the container 102. As shown in FIG. As shown in these figures, in this embodiment, the upper portion of the neck portion 23 forms a step D1 on the radially inner side.

The neck 23 has a first inner surface 41 and a second inner surface 42 both facing the opening S1, and a third inner surface 43 between the inner surfaces 41 and 42 also facing the opening S1. . The first inner surface 41, the third inner surface 43, and the second inner surface 42 are continuous with each other in this order, but are not smoothly continuous at points P3 and P2, which are 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 the points P3 and P2 that are the boundaries between them. In addition, P3 shall represent the point of the upper end of the 3rd inner surface 43. As shown in FIG. 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 of the first inner surface 41 and further located 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 that the first inner surface 41 constitutes , is steeper in the vertical direction than the inclined surface formed 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 interposed therebetween. In addition, although the inclined surface formed by the first inner surface 41 and the third inner surface 43 is linear in the side view in the example of FIG. 7, it may be curved in the 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 inclined state, the volatilization body 3 contacts the upper end point P2 of the 2nd inner surface 42 while the lower end part 3a contacts the outer peripheral part 12 of the bottom part 10. As shown in FIG. At this time, the volatilization body 3 contacts the point P2 of the upper end of the 2nd inner surface 42, maintaining the 1st inner surface 41 and distance. That is, in the most inclined state, since the second inner surface 42 separates the first inner surface 41 and the volatilization body 3, the volatilization body 3 does not contact the first inner surface 41, and the volatilization body 3 and the first inner surface 41 A space S3 is formed therebetween. 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 formed by the axial direction of the volatilization body 3 with the vertical direction, and θ2 be the angle formed between the straight line connecting points P1 and P2 (at the same position in the circumferential direction of the opening S1) and the vertical direction. At this time, θ2>θ1 even in the most inclined state.

Further, the neck portion 23 has an upper surface 44 continuing from the upper end point P1 of the first inner surface 41, and further has an outer wall surface 45 continuing from the radially outermost point P4 of the upper surface 44. As shown in FIG. Both the upper surface 44 and the outer wall surface 45 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 portion of the outer wall surface 45 according to the present embodiment has a rounded shape that protrudes radially outward in a side view. Note that the upper surface 44 may be inclined with respect to the horizontal plane. Also, the upper surface 44 can be omitted.

From the above configuration, the chemical liquid adhering to the outer surface of the volatilization body 3 drips along the outer surface, often the contact between the volatilization body 3 and the neck 23, in this embodiment, the volatilization body 3 and the second inner surface 42 may accumulate in the vicinity of point P2, which is the point of contact with . However, this chemical does not reach the outer wall surface 45 of the container 102 . That is, since the first inner surface 41 extends in the vertical direction, it becomes the outer wall of the space S3, and the space S3 becomes the "medical solution pool". Therefore, the chemical does not reach the outer wall surface 45 beyond the first inner surface 41 and the upper surface 44 . As a result, it is possible to prevent the liquid medicine from dripping along the outer wall surface 45 of the container 102 and staining the outer wall surface 45 with the liquid medicine. As a result, a person's hand, walls, household goods, etc., which touch the outer wall surface 45 of the container 102 are not stained with the chemical solution. In addition, in the present embodiment, the third inner surface 43 forming the bottom surface of the space S3 is inclined downward as it goes radially inward. 3 along the inner surface 43 and returned into the inner space S2 of the container 102 . The same applies to the first inner surface 41 that is inclined downward as it goes radially inward. Therefore, the possibility that the chemical liquid stains 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 vertical length w1 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 0.5 mm≦w1 is preferred, 1.0 mm≦w1 is more preferred, and 2.0 mm≦w1 is further preferred. Moreover, w1 ≤ 30 mm is preferable, w1 ≤ 20 mm is more preferable, and w1 ≤ 10 mm is further preferable. From the same point of view, the horizontal length w2 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 preferably 1.0 mm≦w2. It is more preferable that 0 mm≦w2, and even more preferably 3.0 mm≦w2. Moreover, w2 ≤ 45 mm is preferable, w2 ≤ 30 mm is more preferable, and w2 ≤ 15 mm is even more preferable.
