Description

[Technical field]

[0001] The present invention relates to a chemical volatilizer that volatilizes a liquid chemical having volatility, such as an aromatic or a deodorant. [Background technology]

[0002] In order to eliminate the unpleasant odors in spaces such as indoors and cars and to create a comfortable space, chemical vaporizers that naturally vaporize liquid chemicals are widely used. For example, Patent Document 1 discloses a chemical vaporizer of this type in which a plurality of rod-shaped vaporizers are inserted into a chemical container that contains a liquid chemical. In the chemical vaporizer of Patent Document 1, a portion of the lower end of each vaporizer is immersed in the liquid chemical, while a portion of the upper end of each vaporizer protrudes from the upper opening of the chemical container, and the liquid chemical in the chemical container is sucked up by each vaporizer and vaporized outside the chemical container, thereby exerting an aromatic effect.

[0003] In many cases, pesticide volatilizers are installed in places where people can see them, such as living rooms and entrances, and in recent years, there has been a growing need for pesticide volatilizers that have a high interior design quality. For this reason, natural materials such as rattan and plants, artificial flowers, and resin sticks are mainly used for the volatilizers. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2016-124603 A Summary of the Invention [Problem to be solved by the invention]

[0005] In this type of chemical vaporizer, the vaporizer is placed in the chemical container while wet with the liquid chemical, because the vaporizer absorbs the liquid chemical. However, if the surface of the vaporizer is wet, the vaporizers tend to stick together, and if multiple vaporizers stick together and become dense, the surface area of ​​the vaporizer decreases, reducing the amount of liquid chemical vaporized. In addition, the interior design of the chemical vaporizer is impaired, so there is room for improvement.

[0006] The present invention has been made to solve the above-mentioned problems, and aims to provide a drug volatilizer that can prevent volatilizers from sticking together. [Means for solving the problem]

[0007] The drug volatilizer of the present invention is a drug volatilizer comprising a drug container having an opening at the top for inserting a volatilizer and having a storage space for a liquid drug inside, and a plurality of volatilizers inserted into the drug container through the opening, wherein the drug container has a mouth portion having an inner wall surface that forms the opening, and the inner wall surface of the mouth portion has a plurality of fitting portions along the circumferential direction into which the volatilizers inserted through the opening fit, the inner wall surface of the mouth portion has a polygonal shape in cross section, and the fitting portions are formed by the corners of the polygon, the mouth portion further has a top surface portion at its upper end that is provided to surround the mouth portion, and the upper surface of the top surface portion is connected to the inner wall surface of the mouth portion and is inclined downwardly toward the opening, and an outer peripheral wall portion hangs down from the outer peripheral edge of the top surface portion. Effect of the Invention

[0008] According to the present invention, since a plurality of fittings are provided on the inner wall surface of the mouth portion along the circumferential direction, a plurality of volatilizers inserted into the drug container from the opening of the mouth portion are each fitted into the fittings and leaned against the inner wall surface of the mouth portion, and the fittings can suppress the movement of each volatilizer along the inner wall surface of the mouth portion. Therefore, even if the drug container is moved or the volatilizers are touched by hand, the volatilizers are restricted from moving along the inner wall surface of the mouth portion, so that the volatilizers can be prevented from sticking together and becoming crowded, and a decrease in the amount of volatilization and a loss of interior design can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1 and 2 show a chemical volatilizer 1 of this embodiment. The chemical volatilizer 1 includes a chemical container 2 that contains a liquid chemical L, and a plurality of volatilizers 10 that are inserted into the chemical container 2. The plurality of volatilizers 10 have a lower end portion immersed in the liquid chemical L in the chemical container 2, while a portion of the upper end portion is exposed on the chemical container 2. The chemical volatilizer 1 exerts the efficacy of the liquid chemical in the surrounding space in which the chemical volatilizer 1 is installed by sucking up the liquid chemical L in the chemical container 2 with the plurality of volatilizers 10 and volatilizing it outside the chemical container 2.

[0011] The liquid medicine L has volatility (sustained release of medicinal effect) and exerts its medicinal effect by gradually volatilizing the medicine into the air. The liquid medicine L can be exemplified by, for example, an aromatic, a deodorant, an insect repellent, etc., but is not particularly limited thereto, and can contain a fragrance, a deodorant component, an insect repellent component, a coloring agent, etc., either alone or in combination, depending on the purpose of use. The solvent contained in the liquid medicine L is appropriately selected depending on the type of additive used, and can be a hydrophilic solvent or a lipophilic solvent, or a mixture thereof. When the liquid medicine L 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 isoparaffin solvent, or a mixture thereof can be used. The liquid medicine may contain a dissolving agent to solubilize the fragrance, the deodorant component, the insect repellent component, the coloring agent, etc.

[0012] As shown in Figures 1 to 3, the drug container 2 is a bottomed container having an opening 50 at the top for inserting the volatilizer 10 and an internal storage space 30 for the liquid drug L. In this embodiment, the drug container 2 is composed of a container body 3 having the storage space 30 and a cap 4 having a cylindrical mouth portion 5 with the opening 50 and detachable from the container body 3.

[0013] The container body 3 may be transparent, translucent, or opaque, and may be colorless or colored. Translucent means that the transparency is not completely transparent, but has a degree of transparency that allows the inside to be seen. If the container body 3 is transparent or translucent, the inside of the container body 3 can be seen from the outside, and for example, the remaining amount of the liquid drug L in the container body 3 can be confirmed, which is preferable. The material of the container body 3 is not particularly limited, and can be, for example, glass, plastic, or ceramic, and an appropriate material is selected in consideration of aesthetics.

[0014] As shown in Figure 3, the container body 3 has a neck 31, a shoulder 32 continuous with the lower end of the neck 31, a hollow body 33 continuous with the shoulder 32, and a bottom 34 continuous with the lower end of the body 33.

[0015] The neck portion 31 is cylindrical and has an inlet for the liquid drug L. The neck portion 31 is formed to have a size that allows the mouth portion 5 to be inserted inside when the cap 4 is attached to the container body 3, and the opening 50 of the mouth portion 5 is positioned at the inlet of the neck portion 31, so that the volatilizer 10 inserted into the opening 50 is inserted into the container body 3.

[0016] The shoulder portion 32 has a flat upper surface portion 32A having a circular shape in a plan view and larger than the neck portion 31, a side portion 32B hanging down from the outer periphery of the upper surface portion 32A, and a flat lower surface portion 32C having a circular shape in a plan view and continuing to the lower end of the side portion 32B. The lower surface portion 32C is formed in a size that allows the outer peripheral wall portion 41 of the cap 4 to abut against the outer periphery when the cap 4 is attached to the container body 3.

[0017] 1 to 5, the cap 4 has a top surface 40 that is circular in plan view, a cylindrical outer peripheral wall 41 that hangs down from the outer periphery of the top surface 40, and a cylindrical inner peripheral wall 42 that hangs down from the top surface 40 inside the outer peripheral wall 41. In this embodiment, the cap 4 also has a cylindrical mouth 5. An opening 50 for inserting the volatilizer 10 is formed in the center of the top surface 40, and the top surface 40 is provided at the upper end of the mouth 5 so as to surround the mouth 5.

[0018] The material of the cap 4 is not particularly limited, and may be, for example, metal or plastic, with the material being appropriately selected taking aesthetics into consideration.

[0019] The top surface 40 is connected to the inner wall surface 51 of the mouth portion 5. In this embodiment, the top surface 40 is inclined downward toward the opening 50, and the top surface of the top surface 40 is also inclined when it is connected to the inner wall surface 51 of the mouth portion 5.

[0020] The outer peripheral wall portion 41 has an inverted tapered shape with an outer diameter increasing downward. When the cap 4 is attached to the container body 3, the lower end of the outer peripheral wall portion 41 abuts against the outer peripheral edge of the lower surface portion 32C of the shoulder portion 32 of the container body 3. This makes it possible to cover and hide the neck portion 31 and shoulder portion 32 of the container body 3.

[0021] The inner peripheral wall portion 42 is provided on the top surface portion 40 concentrically with the outer peripheral wall portion 41, and is lower in height than the outer peripheral wall portion 41. When the cap 4 is attached to the container body 3, the inner peripheral surface of the inner peripheral wall portion 42 abuts against the outer peripheral surface of the neck portion 31 of the container body 3. This allows the cap 4 to be attached to the container body 3 in an appropriately positioned state.

[0022] The mouth portion 5 has a cylindrical shape with a predetermined thickness and has an opening 50 on the inside. The opening 50 is formed by an inner wall surface 51 of the mouth portion 5. In this embodiment, the inner wall surface 51 of the mouth portion 5 is composed of a lower vertical surface 51A extending in the up-down direction and an upper inclined surface 51B continuing to the vertical surface 51A, and the inclined surface 51B is continuing to the upper surface of the top surface portion 40. The inclined surface 51B is inclined so as to descend toward the opening 50 at an inclination angle steeper than that of the upper surface of the top surface portion 40.

[0023] A plurality of fitting portions 6 are provided along the circumferential direction at predetermined positions on the upper end side of the inner wall surface 51 of the mouth portion 5. As shown in Figures 1 to 4 and 6, the fitting portions 6 can be formed, for example, by recesses 52 formed by recessing a portion of the inner wall surface 51 of the mouth portion 5. The recesses 52 have a predetermined width w, depth h, and length l.

[0024] The recess 52 may be provided so as to extend in the vertical direction on the vertical surface 51A of the inner wall surface 51 of the mouth portion 5, but in this embodiment, it is provided across the inclined surface 51B and the vertical surface 51A of the inner wall surface 51, and is inclined downward toward the opening 50 at a steeper inclination angle than the inclined surface 51A, with the lower edge being located closer to the opening 50 than the upper edge. The volatilizer 10 inserted into the drug container 2 from the opening 50 is leaned against the inner wall surface 51 of the mouth portion 5 in an inclined state, but since the recess 52 is inclined, the volatilizer 10 can be leaned against the inner wall surface 51 of the mouth portion 5 with a wider range of the volatilizer 10 fitted into the recess 52.

[0025] The shape of the recess 52 is not particularly limited, and in this embodiment, it has a rectangular shape in cross section as shown in Figure 7(a), but it can have various shapes, such as a C-shape in cross section (Figure 7(b)), a trapezoidal shape (Figure 7(c)), an arc shape such as a semicircle (Figure 7(d)), or a triangular shape (Figure 7(e)).

[0026] In the illustrated example, the depth h of the recess 52 changes in the direction of length l, but the depth h may be constant in the direction of length l. In the illustrated example, the depth h of the recess 52 is deepest in the center in the direction of length l and gradually becomes shallower toward one side and the other side in the length direction, but the depth h may change in the direction of length l, for example, by gradually becoming deeper or shallower toward one side in the direction of length l.

[0027] As shown in Figs. 8 and 9, the fitting portion 6 can be formed by a recess 54 between a pair of protrusions 53 protruding from the inner wall surface 51 of the mouth portion 5. The protrusions 53 may be provided so as to extend vertically on the vertical surface 51A of the inner wall surface 51 of the mouth portion 5, or may be provided so as to extend obliquely on the inclined surface 51B. When the protrusions 53 are provided on the inclined surface 51B of the inner wall surface 51 of the mouth portion 5, the recess 54 is inclined along the inclined surface 51B, so that the volatilizer 10 inserted into the drug container 2 from the opening 50 can be leaned against the inner wall surface 51 of the mouth portion 5 in a state where the volatilizer 10 is fitted into the recess 52 over a wider range. The recess 54 has a predetermined width w, depth h, and length l corresponding to the interval, height, and length of the protrusions 53.

[0028] The shape of the protrusion 53 is not particularly limited, and in the examples of Figures 8 and 9, it has a rectangular shape in cross section as shown in Figure 10(a), but it can have various shapes, such as a trapezoidal shape in cross section (Figure 10(b)), a shape with narrow ends (Figure 10(c)), a triangular shape (Figure 10(d)), a semicircular shape (Figure 10(e)), or a circular shape (Figure 10(f)).

[0029] In the illustrated example, the protrusion 53 has a constant height in the length direction (the direction of the length l of the recess 54), but the height may vary in the length direction. For example, the height may be gradually lower or higher toward one side in the length direction, or the height may be highest in the center in the length direction and gradually decrease toward one and the other sides in the length direction. As a result, the depth h of the recess 54 also varies in the direction of the length l.

[0030] The volatilizer 10 inserted from the opening 50 is leaned against the inner wall surface 51 of the mouth portion 5. The fitting portion 6 is a portion of the inner wall surface 51 of the mouth portion 5 into which the volatilizer 10 inserted from the opening 50 fits. In addition, the term "the volatilizer 10 fits" means that all or a part of the volatilizer 10 enters the inside of the fitting portion 6, and refers to a state in which, for example, as shown in Figures 11(a) to (e), all or a part of the volatilizer 10 enters the inside of the fitting portion 6 (recesses 52, 54) and the volatilizer 10 falls into the fitting portion 6 (recesses 52, 54), or, for example, as shown in Figure 11(f), a part of the volatilizer 10 fits snugly inside the fitting portion 6 (recess 52) and the volatilizer 10 is in close contact with the fitting portion 6, or, for example, as shown in Figures 11(g) to (j), a part of the volatilizer 10 is pinched inside the fitting portion 6 (recesses 52, 54) and both sides of the volatilizer 10 are pressed by the fitting portion 6 (recesses 52, 54), thereby restraining the volatilizer 10 by the fitting portion 6 (recesses 52, 54) and making it difficult for the volatilizer 10 to move along the inner wall surface 51 of the mouth portion 5. In this way, the multiple volatilizers 10 inserted through the opening 50 of the mouth portion 5 and leaned against the inner wall surface 51 each enter and fit inside the insertion portion 6, thereby restricting the multiple volatilizers 10 from moving along the inner wall surface 51 of the mouth portion 5, thereby preventing the volatilizers 10 from sticking together and becoming crowded together.

[0031] The width w of the recesses 52, 54 is not particularly limited and is appropriately set according to the thickness of the volatilizer 10, but if the width is greater than or equal to the thickness of the volatilizer 10, the volatilizer 10 falls into the recesses 52, 54 or fits into the recesses 52, 54 to hold the volatilizer 10 in the recesses 52, 54, so that the effect of the present invention can be effectively achieved. For example, when the thickness of the volatilizer 10 is 1.0 mm, the width w of the recesses 52, 54 is preferably 1.0 mm or more, more preferably 1.5 mm or more, and even more preferably 2.0 mm or more. On the other hand, if the width w of the recesses 52, 54 is too large, multiple volatilizers 10 tend to enter inside one recess 52, 54, so when the thickness of the volatilizer 10 is 1.0 mm, the width w of the recesses 52, 54 is preferably 4.0 mm or less, and more preferably 3.0 mm or less. The width w of the recesses 52, 54 refers to the opening width at the top position of the recesses 52, 54 opposite to the bottom.

[0032] The depth h of the recesses 52, 54 is not particularly limited and is appropriately set according to the thickness of the volatilizer 10, but if the depth is such that more than half of the thickness of the volatilizer 10 enters the inside of the recesses 52, 54, the volatilizer 10 is easily held in the recesses 52, 54, so that the effect of the present invention can be effectively achieved. For example, when the thickness of the volatilizer 10 is 1.0 mm, the depth h of the recesses 52, 54 is preferably 0.5 mm or more, more preferably 1.0 mm or more, and even more preferably 2.0 mm or more. On the other hand, if the depth h of the recesses 52, 54 is too large, it is necessary to enlarge the opening 50 of the mouth portion 5, so when the thickness of the volatilizer 10 is 1.0 mm, the depth h of the recesses 52, 54 is preferably 5.0 mm or less, more preferably 4.0 mm or less.

[0033] The length l of the recesses 52, 54 is not particularly limited, but a larger length is preferable because a larger portion of the volatilizer 10 enters inside the recesses 52, 54, and the recesses 52, 54 can effectively restrain the volatilizer 10 and make it difficult to move.For example, a length of 2.0 mm or more is preferable, 4.0 mm or more is more preferable, and 6.0 mm or more is even more preferable.

[0034] The cross-sectional shape of recesses 52, 54 is not particularly limited, but if the width of recesses 52, 54 is constant from the bottom to the top or is smaller at the top than the bottom, as shown in Figures 7(a) to (c) and 10(a) to (c), it becomes difficult for volatilizer 10 to escape from recesses 52, 54, and the effects of the present invention can be effectively achieved.

[0035] The recesses 52, 54 are preferably provided on the inner wall surface 51 of the mouth portion 5 with a gap s (shown in FIG. 6 and FIG. 9) between adjacent recesses 52, 54 in the circumferential direction. By providing the gap s between adjacent recesses 52, 54, the volatilizer 10 is less likely to move to the adjacent recesses 52, 54, so that the volatilizer 10 can be more effectively prevented from sticking to each other and becoming dense. The gap (length in the circumferential direction) s between the recesses 52, 54 is preferably 1.0 mm or more, more preferably 2.0 mm or more, and even more preferably 3.0 mm or more. On the other hand, if the gap s between the recesses 52, 54 is too large, it is necessary to enlarge the opening 50 of the mouth portion 5, so the gap s between the recesses 52, 54 is preferably 6.0 mm or less, and more preferably 5.0 mm or less. It is not necessary to provide the gap s between adjacent recesses 52, 54, and the recesses 52, 54 may be provided continuously without the gap s in the circumferential direction.

[0036] The volatilizer 10 has a longitudinal shape, and in this embodiment, it has a rod shape. The longitudinal shape refers to a shape in which the length in one direction is sufficiently longer than the length in the direction perpendicular to the one direction. The volatilizer 10 does not necessarily have to have a rod shape, and may have, for example, a long and thin plate shape.

[0037] The length (longitudinal size) of the volatilizer 10 is not particularly limited, as long as its upper end protrudes from the upper opening 50 of the drug container 2 and its lower end reaches the inner bottom surface of the bottom 34 of the drug container 2 (preferably the outer peripheral portion of the inner bottom surface), and depending on the size of the drug container 2, it can be, for example, 110 mm or more and 190 mm or less.

[0038] The thickness of the volatilization body 10 is not particularly limited, but a thinner one is preferable from the viewpoint of design because the volatilization body 10 is less noticeable when the drug volatilization device 1 is viewed from the outside, while if it is too thin, it is easy to break, so it is preferable to set the thickness to 1.0 mm or more and 4.0 mm or less. In addition, when the volatilization body 10 is thin and light, the volatilization body 10 is more easily moved, so the effect of the present invention is easily achieved. The thickness of the volatilization body 10 can be defined as the diameter of a circle inscribed in the cross section of the volatilization body 10.

[0039] As shown in FIG. 12, in a cross-sectional view perpendicular to the longitudinal direction, the volatilizer 10 has a plurality of fine striated grooves 11 at intervals in the circumferential direction on the outer periphery, which serve as a flow path through which the liquid medicine L is drawn up in the longitudinal direction so that the liquid medicine L can be drawn up by capillary action. The volatilizer 10 is composed of a shaft portion 12 and a plurality of protrusions 13 that protrude from the outer circumferential surface of the shaft portion 12 and extend in the longitudinal direction around the outer circumferential surface of the shaft portion 12, and a groove 11 exists between adjacent protrusions 13 in the circumferential direction. The outer shape of the cross section of the shaft portion 12 does not necessarily have to be circular, and can be various shapes such as an elliptical shape, a polygonal shape such as a triangular shape or a rectangular shape. The shape of the protrusions 13 (the shape of the grooves 11) is not particularly limited, but in this embodiment, the plurality of protrusions 13 spread out radially from the center of the shaft portion 12. Therefore, the distance (circumferential length) between adjacent protrusions 13 gradually increases toward the top 13A of the protrusions 13; in other words, the width of the groove 11 gradually increases from the groove bottom 11A toward the external space.

[0040] The width W (width at the groove bottom 11A) of the groove 11 of the volatilizer 10 is not particularly limited, but is preferably 0.01 mm or more and 0.15 mm or less so that the liquid medicine L can be rapidly sucked up at room temperature. In addition, the depth H (height of the protrusion 13 from the outer peripheral surface of the shaft portion 12) of the groove 11 of the volatilizer 10 is not particularly limited, but is preferably 0.1 mm or more and 1.0 mm or less because if the groove 11 is too deep, the protrusion 13 is easily broken, while if the groove 11 is too shallow, the amount of liquid medicine L that can be sucked up is reduced.

[0041] As long as the volatilizer 10 can suitably suck up the liquid drug 2 by capillary action, it may have a flow path for another liquid drug L instead of or in addition to the multiple grooves 11. For example, by making the volatilizer 10 have a hollow structure, the cavity 14 extending in the longitudinal direction inside the volatilizer 10 can be used as a flow path for the liquid drug L. In this case, fine grooves may be further provided on the inner peripheral surface of the volatilizer 10.

[0042] The volatilizer 10 is preferably formed of a transparent material. The transparent material may be either colorless or colored. Since the volatilizer 10 is formed of a transparent material, the volatilizer 10 has light transmittance, so that light is less likely to be reflected or refracted at the boundary with the liquid medicine L in the liquid medicine L. Therefore, when the volatilizer 10 is viewed from the outside of the medicine container 2, the part of the volatilizer 10 immersed in the liquid medicine L does not appear to be largely refracted, so that it is possible to suppress the part of the volatilizer 10 immersed in the liquid medicine L from appearing folded by the liquid medicine L or appearing larger than it actually is. In addition, the multiple grooves 11 on the outer periphery increase the surface area that reflects light on the outer surface of the volatilizer 10, and the light is diffusely reflected, making the whole appear to sparkle. As a result, when the volatilizer 10 is viewed from the outside of the drug container 2, even if the part of the volatilizer 10 that is immersed in the liquid drug L appears to be somewhat refracted, the impression that the drug container 2 is glittering due to the large number of volatilizers 10 is not given that the drug container 2 is cluttered with a large number of volatilizers 10. Therefore, even if a large number of volatilizers 10 are inserted into the drug container 2, the aesthetic appearance of the drug volatilizer 1 can be improved, and the interior of the drug volatilizer 1 can be enhanced. Furthermore, even if the liquid drug L is colored, the volatilizer 10 glitters, making it difficult to visually recognize the colored liquid drug L that is sucked up in each groove 11. Therefore, the volatilizer 10 looks almost the same as before the liquid drug L is sucked up, and the volatilizer 10 does not look wet with the liquid drug L. In addition, if the volatilizer 10 is formed of a colorless and transparent material, the effect can be preferably exhibited regardless of the color of the liquid drug L.

[0043] In addition, the volatilizer 10 can be made difficult to see in the liquid medicine L because the liquid medicine L passes through the groove 11 on the outer circumference and / or the cavity 14 inside, and the light is more transmitted through the liquid medicine L and is less likely to be reflected or refracted at the boundary with the liquid medicine L. Therefore, even if a large number of volatilizers 10 are inserted into the medicine container 2, the volatilizers 10 can be almost assimilated with the liquid medicine L, so that the inside of the medicine container 2 is not cluttered with a large number of volatilizers 10, and the aesthetics of the medicine volatilizer 1 can be further improved, and the interior of the medicine volatilizer 1 can be further improved. Note that even if the liquid medicine L is colored, the volatilizer 10 becomes the same color as the external liquid medicine L due to the liquid medicine L passing through the groove 11 on the outer circumference and / or the cavity 14 inside, so that the volatilizer 10 becomes difficult to see in the liquid medicine L. Furthermore, if the volatilizer 10 is the same color or a similar color as the liquid medicine L, the volatilizer 10 can be made even less visible in the liquid medicine L. Note that similar colors refer to similar colors, and refer to colors that are adjacent or close to each other on the color wheel, and examples of such colors include blue and light blue, orange and yellow, and green and yellow-green.

[0044] In addition, the volatilizer 10 is preferably formed of a material having a high affinity with the liquid chemical L. By forming the volatilizer 10 of a material having a high affinity with the liquid chemical L, when the liquid chemical L is sucked up by each groove 11 of the volatilizer 10, the liquid chemical L spreads so as to stick to the surface of the groove 11, and the contact area of ​​the liquid chemical L with the surface of the groove 11 becomes large. Therefore, as shown in FIG. 13, when the liquid chemical L is sucked up by each groove 11 of the volatilizer 10, the height of the liquid level of the liquid chemical L is lower than the depth H of the groove 11 (the height of the protrusion 13), and the liquid level of the liquid chemical L does not rise toward the external space side from the outer edge of the groove 11 (the top 13A of the protrusion 13). Therefore, even if the upper end portion of the volatilizer 10 exposed from the drug container 2 comes into contact with the hand, clothes, curtain, etc., the top 13A of the protrusion 13 will come into contact with the hand, etc. first, making it difficult for the liquid drug L in the groove 11 to adhere to the hand, etc., thereby preventing the hand, etc. from being soiled with the liquid drug L.

[0045] In addition, if the volatilizer 10 is made of a material with low affinity for the liquid drug L, when the liquid drug L is sucked up by each groove 11 of the volatilizer 10, the liquid drug L is repelled by the surface of the groove 11, and the contact area of ​​the liquid drug L with the surface of the groove 11 becomes small. Therefore, as shown in FIG. 14, when the liquid drug L is sucked up by each groove 11 of the volatilizer 10, the height of the liquid level of the liquid drug L becomes higher than the height H of the protrusion 13, and the liquid level of the liquid drug L rises toward the external space side from the top 13A of the protrusion 13. Therefore, when the upper end part of the volatilizer 10 exposed from the drug container 2 touches the hand, clothes, curtain, etc., the liquid drug L in the groove 11 is likely to adhere to the hand, etc.

[0046] Examples of materials having high affinity with the liquid drug L include materials with a contact angle α of the liquid drug L of 90° or less, preferably 70° or less, more preferably 50° or less, more preferably 30° or less, and even more preferably 10° or less, as shown in Fig. 15. This contact angle α can be measured by removing dirt from the surface of a thin plate B (size: 60 mm x 20 mm, thickness: about 5 mm) made of the material used for the volatilizer 10 and having a flat surface, for example, by depositing a droplet of about 6 μL of the liquid drug L on the surface of the thin plate B using a micropipette, and measuring the contact angle α of the droplet after 1000 ms using a contact angle meter (DropMaster500 manufactured by Kyowa Interface Science Co., Ltd., measurement and analysis integrated software: FAMAS).

[0047] Examples of materials that can be used to form the above-mentioned volatilizer 10 include glass and transparent resins, and examples of transparent resins that can be preferably used include polycarbonate, acrylic resin, polypropylene, polyethylene, low-density polyethylene, vinylidene fluoride, polyamide, polystyrene, and vinyl chloride.

[0048] The volatilizer 10 can be formed by a general known molding method (for example, extrusion molding for resin, or draw molding for glass) using the material for forming the volatilizer 10 described above. The volatilizer 10 is preferably formed as a single body (such as a rod-shaped body or a plate-shaped body) by extrusion molding or the like, and is preferably a dense body with no or almost no gaps or holes. As a result, the volatilizer 10 is not substantially impregnated with the liquid agent L, so that the volatilizer 10 does not hold an excessive amount of the liquid agent L, and when the liquid agent L is exhausted from the drug container 2, the volatilizer 10 immediately loses the liquid agent L that it holds, so that the end of use can be easily grasped. In addition, since the volatilizer 10 can eliminate any flow path through which the liquid agent L passes other than the groove 11 on the periphery and the cavity 14 inside, the suction speed of the liquid agent L by the volatilizer 10 can be maintained at a desired set speed.

[0049] The material of the volatilizer 10 is not particularly limited, and the volatilizer 10 may be formed from materials other than those mentioned above. For example, the volatilizer 10 may be formed from a known material that has been conventionally used for the volatilizer 10, such as natural materials such as rattan and plants, and artificial flowers.

[0050] As described above, according to the drug container 2 and the drug volatilizer 1 using the drug container 2, a plurality of fitting portions 6 are provided along the circumferential direction on the inner wall surface 51 of the mouth portion 5, so that a plurality of volatilizers 10 inserted into the drug container 2 from the opening 50 of the mouth portion 5 are each fitted into the fitting portion 6 and leaned against the inner wall surface 51 of the mouth portion 5, and the fitting portion 6 can suppress the movement of each volatilizer 10 along the inner wall surface 51 of the mouth portion 5. Therefore, for example, even if the drug container 2 is moved or the volatilizer 10 is touched by a hand, the volatilizer 10 is restricted from moving along the inner wall surface 51 of the mouth portion 5, so that the volatilizers 10 can be prevented from sticking together and becoming crowded.

[0051] In addition, by inclining the fitting portion 6 downward toward the opening 50, a wider range of the volatilization body 10 can be fitted into the fitting portion 6. Therefore, the fitting portion 6 can more effectively suppress the movement of each volatilization body 10 along the inner wall surface 51 of the mouth portion 5, and more effectively suppress the volatilization bodies 10 from sticking together and becoming crowded.

[0052] In addition, the fitting parts 6 are provided at intervals between adjacent fitting parts 6 in the circumferential direction on the inner wall surface 51 of the mouth part 5, so that the volatilization body 10 is less likely to move to the adjacent fitting parts 6. Therefore, it is possible to more effectively prevent the volatilization bodies 10 from sticking to each other and becoming crowded.

[0053] In addition, since the inner wall surface 51 of the mouth portion 5 includes an inclined surface 51B on the upper side, even if the liquid medicine L sucked up by the volatilizer 10 adheres to the inner wall surface 51 of the mouth portion 5, the liquid medicine L adhered along the inclined surface 51B can be guided from the opening 51 to the inside of the medicine container 2. In addition, since the upper surface of the top surface portion 40 of the cap 4 is inclined so as to descend toward the opening 50, even if the liquid medicine L from the volatilizer 10 drips onto the top surface portion 40 of the cap 4, the liquid medicine L dripped along the upper surface of the top surface portion 40 can be guided from the opening 51 to the inside of the medicine container 2. Therefore, since the liquid medicine L can be prevented from adhering to the upper surface or outer peripheral surface of the medicine container 2, it is possible to prevent the liquid medicine L from dripping on the outer peripheral surface of the medicine container 2 and damaging household goods, and even if the hands, clothes, curtains, etc. touch the medicine container 2, it is possible to prevent the hands, etc. from being stained by the liquid medicine L.

[0054] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention.

[0055] For example, in the above embodiment, the fitting portion 6 is constituted by a recess 52 formed on the inner wall surface 51 of the mouth portion 5, or a recess 54 between a pair of protrusions 53 protruding from the inner wall surface 51 of the mouth portion 5, but as long as the structure is such that the volatilizer 10 can be fitted, various other structures can be adopted. For example, as shown in FIG. 16, the inner wall surface 51 of the mouth portion 5 may be formed into a polygonal shape in cross section, so that the fitting portion 6 is constituted by a corner 55 of the polygonal inner wall surface 51. In this case, too, a part of the volatilizer 10 is sandwiched inside the fitting portion 6 (corner 55) and both sides of the volatilizer 10 are pressed by the fitting portion 6 (corner 55), so that the volatilizer 10 is restrained by the fitting portion 6 (corner 55) and is difficult to move along the inner wall surface 51 of the mouth portion 5. Therefore, the multiple volatilizers 10 inserted through the opening 50 of the mouth portion 5 and leaned against the inner wall surface 51 each fit inside the insertion portion 6 (corner 55), thereby restricting the multiple volatilizers 10 from moving along the inner wall surface 51 of the mouth portion 5, thereby preventing the volatilizers 10 from sticking together and becoming crowded together.

[0056] The polygonal shape of the inner wall surface 51 of the mouth portion 5 is not particularly limited, but the smaller the internal angle of the corner 55, the more preferable it is because the corner 55 can effectively restrain the volatilizer 10 and make it difficult to move, and for example, 150° or less is preferable, and 140° or less is more preferable. On the other hand, if the internal angle of the corner 55 is too small, the number of corners 55 (insertion portions 6) that can be provided on the inner wall surface 51 of the mouth portion 5 is reduced, so for example, 120° or more is preferable, and 130° or more is more preferable. Therefore, it is preferable that the inner wall surface 51 of the mouth portion 5 has a regular hexagonal shape (FIG. 16(a)), a regular octagonal shape (FIG. 16(b)), or a regular dodecagonal shape (FIG. 16(c)) in a cross-sectional view.

[0057] The polygonal shape of the inner wall surface 51 of the mouth 5 has a side length such that the volatilizers 10 are less likely to move to adjacent corners 55, and therefore the volatilizers 10 can be more effectively prevented from sticking together and congesting. The side length is preferably 1.0 cm or more, more preferably 1.5 cm or more, and even more preferably 2.0 cm or more. On the other hand, if the side length is too large, it is necessary to enlarge the opening 50 of the mouth 5, so the side length is preferably 4.0 cm or less, and more preferably 3.0 cm or less.

[0058] In the above embodiment, the inner wall surface 51 of the mouth portion 5 includes the inclined surface 51B on the upper side, but the inner wall surface 51 may be composed of only the vertical surface 51A.

[0059] In addition, in the above embodiment, the drug container 2 is composed of a container body 3 and a cap 4, and the cap 4 is provided with a mouth portion 5 having an opening 50 for inserting the volatile substance 10, but the drug container 2 may be composed of only the container body 3, in which case the neck portion 31 of the container body 3 serves as the mouth portion 5, and an insertion portion 6 can be formed on the inner wall surface of the neck portion 31.
