Description

Technical Field

[0001] The present invention relates to a chemical container used in a chemical diffuser for diffusing a volatile liquid chemical such as a fragrance or a deodorant, and a chemical diffuser provided with the chemical container.

Background Art

[0002] In order to eliminate the discomfort caused by the odor in spaces such as indoors and in vehicles and create a comfortable space, a chemical diffuser that naturally diffuses a liquid chemical is widely used. As this type of chemical diffuser, for example, Patent Document 1 discloses a device in which a plurality of rod-shaped diffusers are inserted into a chemical container containing a liquid chemical. In the chemical diffuser of Patent Document 1, a part of the lower end side of each diffuser is immersed in the liquid chemical, while a part of the upper end side of each diffuser protrudes from the upper opening of the chemical container, and the liquid chemical in the chemical container is sucked up by each diffuser and diffused outside the chemical container, thereby exerting an aromatic effect or the like.

[0003] Chemical diffusers are often installed in places where people can see them, such as in the living room or entrance. In recent years, the need for chemical diffusers with enhanced interior design has been increasing. Therefore, natural materials such as rattan and plants, artificial flowers, resin sticks, etc. are mainly used for the diffusers.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In this type of chemical diffuser, since the diffuser sucks up the liquid chemical, the diffuser is propped up in the chemical container in a state of being wet with the liquid chemical. However, when the surface of the diffuser is wet, the diffusers are likely to stick to each other. When a plurality of diffusers stick together and become dense, the surface area of the diffusers decreases accordingly, resulting in a decrease in the amount of liquid chemical diffused. In addition, there is room for improvement in that the interior design of the chemical diffuser is impaired.

[0006] The present invention was made to solve the above problems, and aims to provide a drug container and a drug disperser that can suppress the adhesion of volatile materials to each other. [Means for solving the problem]

[0007] The present invention relates to a drug container having an opening at the top for inserting a volatile substance and a space for containing a liquid drug inside, characterized in that it comprises a mouth portion having an inner wall surface forming the opening, and the inner wall surface of the mouth portion is provided with a plurality of fitting portions along the circumferential direction into which the volatile substance inserted through the opening fits.

[0008] In the drug container of the present invention, the insertion portion is preferably composed of a recess formed on the inner wall surface of the opening.

[0009] Furthermore, in the drug container of the present invention, it is preferable that the insertion portion is formed by a recess between a pair of protrusions that extend from the inner wall surface of the opening.

[0010] Furthermore, in the drug container of the present invention, it is preferable that the inner wall surface of the mouth portion has a polygonal shape in cross-sectional view, and that the insertion portion is composed of the corners of the polygon.

[0011] Furthermore, in the drug container of the present invention, it is preferable that the insertion portions are provided with a circumferential spacing between adjacent insertion portions and the inner wall surface of the opening.

[0012] Furthermore, in the drug container of the present invention, it is preferable that the insertion portion is inclined to descend as it approaches the opening.

[0013] Furthermore, in the drug container of the present invention, the inner wall surface of the mouth is composed of a lower vertical surface and an upper inclined surface, and it is preferable that the inclined surface slopes downward as it approaches the opening.

[0014] Furthermore, in the drug container of the present invention, it is preferable that a top surface is provided at the upper end of the mouth so as to surround the mouth, and the upper surface of the top surface is connected to the inner wall surface of the mouth and slopes downward as it approaches the opening.

[0015] The present invention is characterized by comprising a drug container having the above-described configuration and a plurality of volatile elements inserted into the drug container. [Effects of the Invention]

[0016] According to the present invention, since multiple fitting portions are provided along the circumferential direction on the inner wall surface of the mouth, by inserting multiple volatile particles into the drug container through the opening of the mouth and placing them against the inner wall surface of the mouth with each particle fitted into its respective fitting portion, the movement of each volatile particle along the inner wall surface of the mouth can be suppressed by the fitting portions. Therefore, even if the drug container is moved or a hand touches the volatile particles, the movement of the volatile particles along the inner wall surface of the mouth is restricted, which prevents the volatile particles from sticking together and becoming densely packed, thus preventing a decrease in the amount of volatile particles released and impairing the aesthetic appeal of the interior.

Mode for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0019] FIG. 1 and FIG. 2 show a medicine diffuser 1 of the present embodiment. The medicine diffuser 1 includes a medicine container 2 that stores a liquid medicine L and a plurality of volatile bodies 10 inserted into the medicine container 2. A part of the lower end side of the plurality of volatile bodies 10 is immersed in the liquid medicine L in the medicine container 2, while a part of the upper end side is exposed on the medicine container 2. The medicine diffuser 1 sucks up the liquid medicine L in the medicine container 2 by the plurality of volatile bodies 10 and volatilizes it outside the medicine container 2, thereby exerting the medicinal effect of the liquid medicine on the surrounding space where the medicine diffuser 1 is installed.

[0020] Liquid agent L is volatile (sustained-release of medicinal effect) and exerts its medicinal effect by gradually volatilizing into the air. Examples of liquid agent L include fragrances, deodorizers, and insect repellents, but it is not particularly limited, and depending on the purpose of use, it may contain fragrances, deodorizing components, insect repellent components, colorants, etc., individually or in combination. The solvent contained in liquid agent L is appropriately selected according to the type of additive used, and may be a hydrophilic solvent, a lipophilic solvent, or a mixture thereof. If liquid agent L contains a fragrance, it is preferable to include at least a lipophilic solvent as the solvent in order to increase the fragrance intensity. Examples of hydrophilic solvents include water or ethanol, or mixtures thereof. Examples of lipophilic solvents include glycol ether or isoparaffinic solvents, or mixtures thereof. The liquid agent may also contain a solubilizer to solubilize fragrances, deodorizing components, insect repellent components, colorants, etc.

[0021] As shown in Figures 1 to 3, the drug container 2 is a bottomed container having an opening 50 at the top into which a volatile substance 10 is inserted, and a storage space 30 for liquid drug L inside. In this embodiment, the drug container 2 consists of a container body 3 having the storage space 30, and a cap 4 that is detachable from the container body 3 and has a cylindrical mouth portion 5 having the opening 50.

[0022] 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 it is transparent enough to allow the contents to be seen. It is preferable that the container body 3 be transparent or translucent so that the contents of the container body 3 can be seen from the outside, for example, to check the remaining amount of liquid drug L inside the container body 3. The material of the container body 3 is not particularly limited and can be made of glass, plastic, or ceramic, for example, and the material is selected appropriately considering aesthetics.

[0023] As shown in Figure 3, the container body 3 comprises a neck portion 31, a shoulder portion 32 continuous with the lower end of the neck portion 31, a hollow body portion 33 continuous with the shoulder portion 32, and a bottom portion 34 continuous with the lower end of the body portion 33.

[0024] The neck portion 31 is cylindrical in shape and has an inlet for the liquid drug L. The neck portion 31 is also sized so that the opening 5 can be inserted through the inside when the cap 4 is attached to the container body 3, and the opening 50 of the opening 5 is positioned at the inlet of the neck portion 31 so that the volatile substance 10 inserted into the opening 50 is inserted into the container body 3.

[0025] The shoulder portion 32 has a larger, circular, flat upper portion 32A in plan view, a side portion 32B hanging down from the outer edge of the upper portion 32A, and a circular, flat lower portion 32C in plan view that is connected to the lower end of the side portion 32B. The lower portion 32C is sized so that the outer peripheral wall portion 41 of the cap 4 can contact the outer edge when the cap 4 is attached to the container body 3.

[0026] As shown in Figures 1 to 5, the cap 4 comprises a top surface portion 40 that is circular in plan view, a cylindrical outer peripheral wall portion 41 that hangs down from the outer peripheral edge of the top surface portion 40, and a cylindrical inner peripheral wall portion 42 that hangs down from the top surface portion 40 inside the outer peripheral wall portion 41. In this embodiment, the cap 4 also has a cylindrical mouth portion 5. An opening 50 for inserting the volatile material 10 is located in the center of the top surface portion 40, and the top surface portion 40 is provided at the upper end of the mouth portion 5 so as to surround the mouth portion 5.

[0027] The material of cap 4 is not particularly limited and can be, for example, metal or plastic, and the material is selected appropriately considering aesthetics.

[0028] The top surface 40 is connected to the inner wall surface 51 of the opening 5. In this embodiment, the top surface 40 is inclined downwards as it approaches the opening 50, and the upper surface of the top surface 40 is similarly inclined and connected to the inner wall surface 51 of the opening 5.

[0029] The outer peripheral wall portion 41 has an inverse tapered shape, with its outer diameter increasing towards the bottom. 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 allows the cap to cover and conceal the neck portion 31 and shoulder portion 32 of the container body 3.

[0030] 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.

[0031] The mouth portion 5 is cylindrical in shape with a predetermined wall thickness and has an opening 50 on its inside. The opening 50 is formed by the 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 vertical direction and an upper inclined surface 51B connected to the vertical surface 51A, with the inclined surface 51B connected to the upper surface of the top portion 40. The inclined surface 51B is inclined at a steeper angle than the upper surface of the top portion 40 and slopes downward towards the opening 50.

[0032] Multiple fitting portions 6 are provided along the circumferential direction at predetermined positions on the upper end of the inner wall surface 51 of the opening 5. As shown in Figures 1 to 4 and Figure 6, the fitting portions 6 can be formed, for example, by recessing a portion of the inner wall surface 51 of the opening 5 into a recess 52. The recess 52 has a predetermined width w, depth h, and length l.

[0033] The recess 52 may be provided so as to extend vertically on the vertical plane 51A of the inner wall surface 51 of the mouth 5, but in this embodiment, it is provided spanning the inclined surface 51B and the vertical plane 51A of the inner wall surface 51, and is inclined at a steeper angle than the inclined surface 51A, and slopes downward as it approaches the opening 50, with the lower edge located closer to the opening 50 than the upper edge. The volatile material 10 inserted into the drug container 2 from the opening 50 is leaned against the inner wall surface 51 of the mouth 5 in an inclined state, but because the recess 52 is inclined, the volatile material 10 can be leaned against the inner wall surface 51 of the mouth 5 with a wider area of ​​the volatile material 10 fitted into the recess 52.

[0034] The shape of the recess 52 is not particularly limited. In this embodiment, it has a rectangular cross-sectional shape as shown in Figure 7(a), but it can have various shapes, such as a C-shape (Figure 7(b)), a trapezoid (Figure 7(c)), an arc shape such as a semicircle (Figure 7(d)), or a triangular shape (Figure 7(e)) in cross-sectional view.

[0035] 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. Also, in the illustrated example, the depth h of the recess 52 is deepest at the center in the direction of length l and gradually decreases towards one side and the other side in the direction of length, but the depth h may change in the direction of length l, for example, by gradually increasing or decreasing towards one side in the direction of length l.

[0036] As shown in Figures 8 and 9, the fitting portion 6 can also be formed by a recess 54 between a pair of projections 53 protruding from the inner wall surface 51 of the opening 5. The projections 53 may be provided so as to extend vertically on the vertical plane 51A of the inner wall surface 51 of the opening 5, or they may be provided so as to extend diagonally on the inclined surface 51B. If the projections 53 are provided on the inclined surface 51B of the inner wall surface 51 of the opening 5, the recess 54 will be inclined along the inclined surface 51B, so that the volatile material 10 inserted into the drug container 2 from the opening 50 can be fitted into the recess 52 over a wider area and the volatile material 10 can be leaned against the inner wall surface 51 of the opening 5. The recess 54 has a predetermined width w, depth h and length l corresponding to the spacing, height and length of the projections 53.

[0037] The shape of the projection 53 is not particularly limited. In the examples in Figures 8 and 9, it has a rectangular cross-sectional shape 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 both sides constricted (Figure 10(c)), a triangular shape (Figure 10(d)), a semicircular shape (Figure 10(e)), or a circular shape (Figure 10(f)).

[0038] In the illustrated example, the height of the projection 53 is constant in the longitudinal direction (the direction of the length l of the recess 54), but the height may vary in the longitudinal direction. For example, the height may gradually decrease or increase towards one side in the longitudinal direction, or the height may be highest in the center in the longitudinal direction and gradually decrease towards one side and the other side in the longitudinal direction. As a result, the depth h of the recess 54 also changes in the direction of length l.

[0039] The volatile material 10 inserted through the opening 50 is propped against the inner wall surface 51 of the mouth 5. The fitting portion 6 is the part of the inner wall surface 51 of the mouth 5 into which the volatile material 10 inserted through the opening 50 fits. Furthermore, when we say that the volatile element 10 is fitted, it means that all or part of the volatile element 10 enters the inside of the fitting portion 6. For example, as shown in Figures 11(a) to (e), all or part of the volatile element 10 enters the inside of the fitting portion 6 (recesses 52, 54) and the volatile element 10 falls into the fitting portion 6 (recesses 52, 54); for example, as shown in Figure 11(f), a part of the volatile element 10 fits snugly inside the fitting portion 6 (recess 52) and the volatile element 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 volatile element 10 is sandwiched inside the fitting portion 6 (recesses 52, 54) and both sides of the volatile element 10 are pressed down by the fitting portion 6 (recesses 52, 54), resulting in a state in which the volatile element 10 is restrained by the fitting portion 6 (recesses 52, 54) and it becomes difficult for it to move along the inner wall surface 51 of the opening 5. In this way, the multiple volatile particles 10 that are inserted through the opening 50 of the mouth portion 5 and leaned against the inner wall surface 51 each fit inside the fitting portion 6, thereby restricting the movement of the multiple volatile particles 10 along the inner wall surface 51 of the mouth portion 5, and thus preventing the volatile particles 10 from sticking together and becoming densely packed.

[0040] The width w of the recesses 52 and 54 is not particularly limited and is set appropriately according to the thickness of the volatilizer 10. However, if the width is greater than or equal to the thickness of the volatilizer 10, the volatilizer 10 will fall into or fit into the recesses 52 and 54 and be held in place by the recesses 52 and 54, thereby effectively demonstrating the effects of the present invention. For example, if the thickness of the volatilizer 10 is 1.0 mm, the width w of the recesses 52 and 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 and 54 is too large, multiple volatilizers 10 will easily fit inside one recess 52 or 54. Therefore, if the thickness of the volatilizer 10 is 1.0 mm, the width w of the recesses 52 and 54 is preferably 4.0 mm or less, and more preferably 3.0 mm or less. Note that the width w of the recesses 52 and 54 refers to the opening width at the top position opposite the bottom of the recesses 52 and 54.

[0041] The depth h of the recesses 52 and 54 is not particularly limited and is set appropriately according to the thickness of the volatilizer 10. However, if the depth is such that more than half of the thickness of the volatilizer 10 is inserted into the inside of the recesses 52 and 54, the volatilizer 10 is more easily held in the recesses 52 and 54, and the effects of the present invention can be effectively demonstrated. For example, if the thickness of the volatilizer 10 is 1.0 mm, the depth h of the recesses 52 and 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 and 54 is too large, it becomes necessary to enlarge the opening 50 of the mouth portion 5. Therefore, if the thickness of the volatilizer 10 is 1.0 mm, the depth h of the recesses 52 and 54 is preferably 5.0 mm or less, and more preferably 4.0 mm or less.

[0042] The length l of the recesses 52 and 54 is not particularly limited, but a larger length is preferable because a larger portion of the volatile material 10 will enter the inside of the recesses 52 and 54, and the recesses 52 and 54 can effectively restrain the volatile material 10, making it difficult for it to move. For example, a length of 2.0 mm or more is preferred, 4.0 mm or more is more preferred, and 6.0 mm or more is even more preferred.

[0043] The cross-sectional shape of the recesses 52 and 54 is not particularly limited, but as shown in Figures 7(a) to (c) and 10(a) to (c), if the width of the recesses 52 and 54 is constant from the bottom to the top, or if the top is smaller than the bottom, the volatile material 10 will have difficulty escaping from the recesses 52 and 54, thereby effectively demonstrating the effects of the present invention.

[0044] It is preferable that the recesses 52 and 54 are provided on the inner wall surface 51 of the mouth 5 with a gap s (shown in Figures 6 and 9) between adjacent recesses 52 and 54 in the circumferential direction. By providing a gap s between adjacent recesses 52 and 54, it becomes more difficult for the volatile material 10 to move between the adjacent recesses 52 and 54, thereby more effectively suppressing the volatile material 10 from sticking together and becoming densely packed. The gap s (circumferential length) between the recesses 52 and 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 and 54 is too large, it becomes necessary to enlarge the opening 50 of the mouth 5, so the gap s between the recesses 52 and 54 is preferably 6.0 mm or less, and more preferably 5.0 mm or less. Note that it is not always necessary to leave a gap s between adjacent recesses 52 and 54, and the recesses 52 and 54 may be provided continuously without a gap s in the circumferential direction.

[0045] The volatile element 10 has a longitudinal shape, and in this embodiment, it has a rod shape. A longitudinal shape means a shape in which the length in one direction is sufficiently longer than the length in the direction perpendicular to that direction. Note that the volatile element 10 does not necessarily have to have a rod shape; for example, it may have a long, slender plate shape.

[0046] The length (length in the longitudinal direction) of the volatile material 10 is not particularly limited, as long as its upper end protrudes from the opening 50 at the top of the drug container 2 and its lower end reaches the inner bottom surface (preferably the outer circumference of the inner bottom surface) of the bottom 34 of the drug container 2. The length depends on the size of the drug container 2, but for example, it can be 110 mm or more and 190 mm or less.

[0047] The thickness of the volatilizing element 10 is not particularly limited, but a thinner element is preferable from a design standpoint because it is less conspicuous when the chemical volatilizer 1 is viewed from the outside. However, if it is too thin, it becomes easily broken, so it is preferable that the thickness be between 1.0 mm and 4.0 mm. Also, if the volatilizing element 10 is thin and light, it is easier to move, so the effects of the present invention are more easily achieved. The thickness of the volatilizing element 10 can be defined by the diameter of the circle inscribed in the cross-section of the volatilizing element 10.

[0048] As shown in Figure 12, the volatilizer 10 has multiple fine, ridge-like grooves 11 on its outer circumference, spaced circumferentially, which serve as channels through which the liquid drug L is drawn up in the longitudinal direction, so that the liquid drug L can be drawn up by capillary action. The volatilizer 10 consists of a shaft portion 12 and multiple protrusions 13 that protrude from the outer surface of the shaft portion 12 and extend longitudinally along the outer surface of the shaft portion 12, with grooves 11 existing between adjacent protrusions 13 in the circumferential direction. The cross-sectional shape of the shaft portion 12 does not necessarily have to be circular, and can be various shapes such as elliptical, triangular, or quadrangular polygons. The shape of the protrusions 13 (shape of the grooves 11) is not particularly limited, but in this embodiment, multiple protrusions 13 radiate outwards from the center of the shaft portion 12. Therefore, the spacing (circumferential length) between adjacent protrusions 13 gradually widens as you move towards the top 13A of the protrusion 13; in other words, the width of the groove 11 gradually widens as you move from the groove bottom 11A toward the external space.

[0049] The width W of the groove 11 of the volatilizer 10 (width at the bottom of the groove 11A) is not particularly limited, but it is preferable to set it to 0.01 mm or more and 0.15 mm or less so that the liquid drug L can be rapidly drawn up at room temperature. The depth H of the groove 11 of the volatilizer 10 (height of the protrusion 13 from the outer surface of the shaft portion 12) is not particularly limited, but it is preferable to set it to 0.1 mm or more and 1.0 mm or less, because if the groove 11 is too deep the protrusion 13 is prone to breaking, and if the groove 11 is too shallow the amount of liquid drug L that can be drawn up is reduced.

[0050] The volatilizer 10 may be provided with other channels for the liquid drug L in place of or in addition to the multiple grooves 11, provided that it can suitably draw up the liquid drug L by capillary action. For example, by making the volatilizer 10 a hollow structure, a cavity 14 extending in the longitudinal direction inside the volatilizer 10 can be used as a channel for the liquid drug L. In this case, fine grooves may be further provided on the inner surface of the volatilizer 10.

[0051] The volatilizer 10 is preferably made of a transparent material. The transparent material may be colorless or colored. Because the volatilizer 10 is made of a transparent material, it is light-transmitting, so light is less likely to be reflected or refracted at the boundary with the liquid drug L. Therefore, when the volatilizer 10 is viewed from the outside of the drug container 2, the part of the volatilizer 10 immersed in the liquid drug L is not visible due to significant refracting, thus preventing the part of the volatilizer 10 immersed in the liquid drug L from appearing to be folded at the liquid drug L's surface or appearing larger than it actually is. Furthermore, the multiple grooves 11 on the outer circumference increase the surface area of ​​the volatilizer 10 that reflects light, and the overall appearance becomes sparkly due to diffuse reflection of light. As a result, when viewing the volatile particles 10 from the outside of the drug container 2, even if the portion of the volatile particles 10 immersed in the liquid drug L appears slightly refracted, it does not give the impression that the drug container 2 is cluttered with numerous volatile particles 10, but rather that the drug container 2 is sparkling due to the numerous volatile particles 10. Therefore, even if numerous volatile particles 10 are inserted into the drug container 2, the aesthetics of the drug disperser 1 can be improved, and the interior design of the drug disperser 1 can be enhanced. Furthermore, even if the liquid drug L is colored, the sparkling appearance of the volatile particles 10 makes it difficult to see the colored liquid drug L being drawn up in each groove 11. Therefore, the volatile particles 10 appear to look almost the same as before the liquid drug L was drawn up, and it is possible to avoid the appearance that the volatile particles 10 are wet with the liquid drug L. Incidentally, if the volatile particles 10 are formed from a colorless and transparent material, this effect can be suitably achieved regardless of the color of the liquid drug L.

[0052] In addition, as the liquid chemical L passes through the grooves 11 on the outer circumference and / or the internal cavity 14 of the volatile element 10 by suction, more light is transmitted through the liquid chemical L, making it less likely for light to be reflected or refracted at the boundary with the liquid chemical L. Therefore, the volatile element 10 can be made less visible within the liquid chemical L. Thus, even if a large number of volatile elements 10 are inserted into the chemical container 2, the volatile elements 10 can be made to blend almost completely with the liquid chemical L. This prevents the inside of the chemical container 2 from becoming cluttered with numerous volatile elements 10, further improving the aesthetics of the chemical volatilizer 1 and enhancing its interior design appeal. Furthermore, even if the liquid chemical L is colored, the volatile element 10 becomes mostly the same color as the external liquid chemical L due to the liquid chemical L passing through the grooves 11 on the outer circumference and / or the internal cavity 14, making the volatile element 10 less visible within the liquid chemical L. Furthermore, if the volatile substance 10 is the same color as or a similar color to the liquid chemical L, the volatile substance 10 can be made even less visible within the liquid chemical L. Note that similar colors refer to colors that are close together or adjacent on the color wheel, such as blue and light blue, orange and yellow, or green and yellow-green.

[0053] Furthermore, it is preferable that the volatilizer 10 be made of a material with high affinity for the liquid drug L. When the volatilizer 10 is made of a material with high affinity for the liquid drug L, when the liquid drug L is drawn up in each groove 11 of the volatilizer 10, the liquid drug L spreads out so that it adheres firmly to the surface of the groove 11, and the area in contact with the surface of the groove 11 of the liquid drug L becomes large. As a result, as shown in Figure 13, when the liquid drug L is drawn up in each groove 11 of the volatilizer 10, the height of the liquid level of the liquid drug L becomes lower than the depth of the groove 11 (height of the protrusion 13) H, and the liquid level of the liquid drug L does not rise beyond the outer edge of the groove 11 (top 13A of the protrusion 13) toward the external space. Therefore, even if a hand, clothing, curtain, etc., touches the upper end portion of the volatile body 10 that is exposed from the chemical container 2, the top 13A of the protrusion 13 will be the first to touch the hand, etc., making it difficult for the liquid chemical L in the groove 11 to adhere to the hand, etc., thus preventing the hand, etc. from being soiled by the liquid chemical L.

[0054] Furthermore, if the volatilizer 10 is made of a material with low affinity for the liquid drug L, when the liquid drug L is drawn up in each groove 11 of the volatilizer 10, the surface of the groove 11 repels the liquid drug L, reducing the contact area between the liquid drug L and the surface of the groove 11. As a result, as shown in Figure 14, when the liquid drug L is drawn up in each groove 11 of the volatilizer 10, 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 towards the external space beyond the top 13A of the protrusion 13. Therefore, if a hand, clothing, curtain, etc., touches the upper end portion of the volatilizer 10 that is exposed from the drug container 2, the liquid drug L in the groove 11 is more likely to adhere to the hand, etc.

[0055] Examples of materials with high affinity for the liquid drug L include materials with a contact angle α 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 Figure 15. This contact angle α is made from the material used in the volatilizer 10. After removing dirt from the surface of a thin plate B (size: 60mm x 20mm, thickness: approximately 5mm) with a flat surface, for example, a droplet of about 6μL of liquid drug L is dropped onto the surface of the thin plate B using a micropipette, and the contact angle α of the droplet after 1000ms can be measured using a contact angle meter (DropMaster500, manufactured by Kyowa Interface Chemical Co., Ltd., measurement and analysis integrated software: FAMAS).

[0056] As the material for forming the volatile substance 10 described above, for example, glass or a transparent resin can be used, and as the transparent resin, for example, polycarbonate, acrylic resin, polypropylene, polyethylene, low-density polyethylene, vinylidene fluoride, polyamide, polystyrene, vinyl chloride, etc. can be preferably used.

[0057] The volatilizer 10 can be formed using the materials described above for forming the volatilizer 10 by a commonly known molding method (for example, extrusion molding for resins, or drawing molding for glass). Preferably, the volatilizer 10 is formed by extrusion molding or the like to be a single piece (such as a single rod or plate), and preferably a dense body with no or almost no gaps or pores. As a result, the volatilizer 10 is not substantially impregnated with liquid drug L, so the volatilizer 10 does not retain an excessive amount of liquid drug L, and when the liquid drug L is depleted from the drug container 2, the volatilizer 10 also immediately loses the liquid drug L it is retaining, making it easy to determine the end of use. Furthermore, since there are no other channels through which the liquid drug L passes in the volatilizer 10 other than the grooves 11 on the outer circumference and the internal cavities 14, the suction rate of the liquid drug L by the volatilizer 10 can be maintained at a desired set rate.

[0058] The material of the volatile element 10 is not particularly limited, and the volatile element 10 may be formed from materials other than those described above. For example, the volatile element 10 may be formed from known materials that have been conventionally used for volatile elements 10, such as natural materials like rattan or plants, or artificial flowers.

[0059] As described above, with the drug container 2 and the drug disperser 1 using the drug container 2, since multiple fitting parts 6 are provided along the circumferential direction on the inner wall surface 51 of the mouth 5, by inserting multiple volatile particles 10 into the drug container 2 through the opening 50 of the mouth 5 and fitting each of them into the fitting part 6, and then leaning them against the inner wall surface 51 of the mouth 5, the movement of each volatile particle 10 along the inner wall surface 51 of the mouth 5 can be suppressed by the fitting parts 6. Therefore, even if the drug container 2 is moved or a hand touches the volatile particles 10, the movement of the volatile particles 10 along the inner wall surface 51 of the mouth 5 is restricted, thus preventing the volatile particles 10 from sticking together and becoming densely packed.

[0060] Furthermore, by inclining the fitting portion 6 downwards as it approaches the opening 50, a wider area of ​​the volatile material 10 can be fitted into the fitting portion 6. Therefore, the fitting portion 6 can more effectively suppress the movement of each volatile material 10 along the inner wall surface 51 of the opening 5, and can more effectively suppress the volatile material 10 from sticking together and becoming densely packed.

[0061] Furthermore, the fitting portions 6 are provided on the inner wall surface 51 of the opening 5 with a gap between adjacent fitting portions 6 in the circumferential direction, making it difficult for the volatile particles 10 to move to adjacent fitting portions 6. Therefore, the adhesion and clustering of the volatile particles 10 can be more effectively suppressed.

[0062] Furthermore, because the inner wall surface 51 of the mouth 5 includes an upward-facing inclined surface 51B, even if the liquid chemical L absorbed by the volatile material 10 adheres to the inner wall surface 51 of the mouth 5, the liquid chemical L adhering along the inclined surface 51B can be guided into the inside of the chemical container 2 through the opening 51. Also, because the upper surface of the top surface 40 of the cap 4 slopes downward towards the opening 50, even if the liquid chemical L from the volatile material 10 drips onto the top surface 40 of the cap 4, the liquid chemical L dripping along the upper surface of the top surface 40 can be guided into the inside of the chemical container 2 through the opening 51. Therefore, it is possible to prevent the liquid chemical L from adhering to the top surface or outer surface of the chemical container 2, thus preventing the liquid chemical L from dripping onto household goods and damaging them. Furthermore, even if hands, clothes, curtains, etc. come into contact with the chemical container 2, it is possible to prevent hands, etc. from being soiled by the liquid chemical L.

[0063] 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 invention.

[0064] For example, in the above embodiment, the fitting portion 6 is composed of a recess 52 formed in the inner wall surface 51 of the mouth portion 5, and a recess 54 between a pair of protrusions 53 protruding from the inner wall surface 51 of the mouth portion 5. However, it is not particularly limited as long as it is a structure in which the volatile material 10 can be fitted, and various other structures can be adopted. For example, as shown in Figure 16, the inner wall surface 51 of the mouth portion 5 may be formed in a polygonal shape in cross-section, and the fitting portion 6 may be composed of the corners 55 of the polygonal inner wall surface 51. In this case as well, a part of the volatile material 10 is sandwiched inside the fitting portion 6 (corner 55), and both sides of the volatile material 10 are pressed down by the fitting portion 6 (corner 55), so the volatile material 10 is restrained by the fitting portion 6 (corner 55) and it becomes difficult for it to move along the inner wall surface 51 of the mouth portion 5. Therefore, when the multiple volatile particles 10 inserted through the opening 50 of the mouth portion 5 and leaned against the inner wall surface 51 are fitted inside the fitting portion 6 (corner 55), the movement of the multiple volatile particles 10 along the inner wall surface 51 of the mouth portion 5 is restricted, thus preventing the volatile particles 10 from sticking together and becoming densely packed.

[0065] The polygonal shape of the inner wall surface 51 of the opening 5 is not particularly limited, but the smaller the interior angle of the corners 55, the more effectively the corners 55 can restrain the volatile material 10 and make it difficult for it to move, so it is preferable that the angle is 150° or less, and more preferably 140° or less. On the other hand, if the interior angle of the corners 55 is too small, the number of corners 55 (insertion parts 6) that can be provided on the inner wall surface 51 of the opening 5 will decrease, so it is preferable that the angle is 120° or more, and more preferably 130° or more. For this reason, it is preferable that the inner wall surface 51 of the opening 5 has a regular hexagonal shape (Figure 16(a)), a regular octagonal shape (Figure 16(b)), or a regular dodecagonal shape (Figure 16(c)) in cross-sectional view.

[0066] The polygonal shape of the inner wall surface 51 of the mouth 5 is such that the longer the side length, the less likely the volatile particles 10 are to move to adjacent corners 55, thus more effectively suppressing the adhesion and concentration of the volatile particles 10. 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 becomes 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.

[0067] Furthermore, in the above embodiment, the inner wall surface 51 of the mouth 5 includes an inclined surface 51B on the upper side, but the inner wall surface 51 may consist only of a vertical surface 51A.

[0068] Furthermore, in the above embodiment, the top surface 40 of the cap 4 is inclined, but the top surface of the top surface 40 does not necessarily have to be inclined and may be horizontal.

[0069] Furthermore, 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. However, 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 can be used as the mouth portion 5, and a fitting portion 6 can be formed on the inner wall surface of the neck portion 31.
