Description

[Technical Field]

[0001] The present invention relates to a chemical solution volatilizer. [Background technology]

[0002] Conventionally, chemical liquid volatilizers have been known in which a rod-shaped volatilizer is inserted into a container containing a chemical liquid so that it protrudes from the container (see, for example, Patent Documents 1 and 2). 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 the effects of the chemical liquid, such as its aromatic properties, to the external space. In many cases, the volatilizer is set so that it is tilted at an appropriate angle within the container to improve the interior design. [Prior art documents] [Patent documents]

[0004] In the chemical solution volatilizers described above, some of the chemical solution absorbed by the volatilizer may leak onto the top surface of the container and adhere thereto. Also, if a large amount of chemical solution leaks from the volatilizer due to environmental conditions such as the ambient temperature and humidity, the chemical solution may fall from the outer periphery of the top surface and contaminate the sides of the container and the surrounding environment.

[0005] The present invention aims to prevent leaked chemical liquid from contaminating the outer surface of the container and the surrounding environment in a chemical liquid volatilizer that uses a rod-shaped volatilizer to suck up and volatilize the chemical liquid in the container. [Means for solving the problem]

The top surface faces the opening, extends circumferentially around the opening, and has corners that are contactable with the volatilizer inserted into the container. The corners are rounded in a longitudinal cross-sectional view.

[0007] A chemical solution volatilizer according to a second aspect of the present invention is the chemical solution volatilizer according to the first aspect, wherein the top surface includes a first surface surrounding the corner portion from the outside, and the upper surface of the first surface is inclined upward radially outward.

[0008] A chemical solution volatilizer according to a third aspect of the present invention is the chemical solution volatilizer according to the second aspect, wherein the upper surface of the first surface portion extends linearly in a vertical cross-sectional view.

[0009] A chemical solution volatilizer according to a fourth aspect of the present invention is the chemical solution volatilizer according to the first or second aspect, wherein the top surface portion further includes a second surface portion that surrounds the first surface portion from the outside.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, a chemical solution volatilizer 1 according to one embodiment of the present invention will be described with reference to the drawings.

[0016] <1. Overall structure of chemical volatilizer> FIG. 1 shows a perspective view of a chemical liquid volatilizer 1 according to one embodiment of the present invention. As shown in the figure, the chemical liquid volatilizer 1 comprises a container 2 in which a chemical liquid is stored and at least one rod-shaped volatilizer 3 inserted into the container 2. The container 2 has an opening S1 at the top, and the volatilizer 3 is inserted into the container 2 through this opening S1. In this specification, "upper" and "lower" are defined based on the usage state shown in FIG. 1, unless otherwise specified.

[0017] The chemical solution used here is not particularly limited in type, but is typically an air freshener, deodorant, or insect repellent, or a mixture thereof, and may contain additives such as fragrances, deodorizing components, insect repellent components, and colorants depending on the intended use. The solvent contained in the chemical solution is appropriately selected depending on the type of additive used and may be a hydrophilic solvent, a lipophilic solvent, or a mixture thereof. When the chemical solution contains a fragrance, it is preferable to contain at least a lipophilic solvent as the solvent to enhance the fragrance intensity. Examples of hydrophilic solvents that can be used include water, ethanol, or a mixture thereof. Examples of lipophilic solvents that can be used include glycol ethers, isoparaffin-based solvents, or a mixture thereof. The chemical solution may also contain a solubilizer to solubilize functional components such as fragrances, deodorant components, insect repellent components, and colorants.

[0018] The rod-shaped volatilizer 3 is inserted into the container 2 in such a way that a portion of it protrudes from the container 2. In other words, the volatilizer 3 has a length sufficient for the height of the container 2, and is inserted into the container 2 in such a way that the lower end 3a is positioned inside the container 2 and the upper end 3b is exposed outside the container 2. At this time, in order to improve the interior appearance of the chemical solution volatilizer 1, the volatilizer 3 is set in the container 2 in a state inclined relative to the vertical direction. Furthermore, as shown in Figure 1, when multiple volatilizers 3 are used at the same time, these volatilizers 3 are set in the container 2 so that they face in various directions and extend radially.

[0019] As will be described later, the volatilizer 3 has a structure that allows it to suck up the liquid medicine against gravity by capillary action. As a result, the liquid medicine in the container 2 can rise from the lower end 3a to the upper end 3b along the volatilizer 3, and volatilize (naturally transpire) from the outer surface of the volatilizer 3 into the external space. This causes the liquid medicine to diffuse into the space surrounding the liquid medicine volatilizer 1.

[0020] The shape and material of the volatilizer 3 are not particularly limited as long as it can absorb the chemical solution and volatilize it to the outside. The volatilizer 3 typically has an elongated, approximately cylindrical shape with internal micropores. It can be made of natural materials such as rattan, or synthetic resins such as polyethylene and polyacetal. The volatilizer 3 according to this embodiment has a cross-sectional shape shown in FIG. 2. In this example, the volatilizer 3 is made of polyethylene terephthalate and polyurethane and has numerous irregular micropores 31 inside. Furthermore, numerous grooves 32 are formed on the outer surface of the volatilizer 3. These grooves 32 extend in a strip-like pattern from the lower end 3a to the upper end 3b along the axial direction of the volatilizer 3. In other words, the cross-section of the volatilizer 3 does not have a smooth outline along the circumferential direction, but rather has an uneven outline. Furthermore, these grooves 32 are arranged at approximately equal intervals along the circumferential direction of the volatilizer 3. Due to capillary action, the chemical solution is absorbed not only through the micropores 31 but also along the grooves 32. Therefore, a large amount of chemical liquid is likely to adhere to the outer surface of the volatilizer 3 of this embodiment.

[0021] <2. Container details> Fig. 3 shows a perspective view of the container 2, and Fig. 4 shows a longitudinal cross-sectional view of the container 2. As shown in these figures, the container 2 according to this embodiment includes a container body 4 and a cover member 5 attached to the container body 4.

[0022] <2-1. Container body> The container body 4 has a bottom surface 10. In this embodiment, the bottom surface 10 has a shape in which its peripheral edge 12 is recessed more than its central edge 11. Therefore, when the amount of chemical solution remaining in the container 2 becomes small, it accumulates in the recess in the peripheral edge 12 of the bottom surface 10. Meanwhile, the lower end 3a of the rod-shaped volatilizer 3 is often positioned on the peripheral edge 12 of the bottom surface 10. Therefore, the configuration allows the volatilizer 3 and the chemical solution to easily come into contact with each other, so that the chemical solution can be used up to the last drop.

[0023] The container body 4 has a cylindrical body 21 that rises from the bottom 10 along its outer periphery, a shoulder 22 that continues to the upper end of the body 21, and a neck 23 that continues to the upper end of the shoulder 22. In this embodiment, although not limited thereto, the bottom 10, body 21, shoulder 22, and neck 23 all have substantially circular outer shapes in a plan view, and their centers are aligned. The neck 23 is a cylindrical portion that forms a mouth that communicates with the opening S1 at the top of the container 2. Hereinafter, the neck 23 will be referred to as the mouth, and may also be given the same reference numeral 23.

[0024] The mouth 23 has a smaller diameter than the body 21. As a result, when the liquid medicine volatilizer 1 falls over, the shoulder 22 acts as a wall, making it difficult for the liquid medicine to spill through the opening S1. In particular, in this embodiment, the mouth 23 is arranged coaxially with the body 21, so the shoulder 22 acts as a wall regardless of the direction in which the liquid medicine volatilizer 1 falls, making it possible to prevent the liquid medicine from spilling. Furthermore, because the cross-sectional area of the opening S1 is smaller than the cross-sectional area of the body 21, it is possible to reduce the amount of liquid medicine that naturally evaporates from the container 2 through the opening S1 relative to the amount of liquid medicine contained in the container 2.

[0025] In this embodiment, the shoulder portion 22 has a step, and includes a lower step portion 221 and an upper step portion 222 located above the lower step portion 221. In a plan view, the lower step portion 221 is disposed so as to surround the upper step portion 222 from the outside. In addition, the upper end portion 231 of the mouth portion 23 is formed in a flange shape. Hereinafter, the upper end portion 231 will be referred to as the flange portion, and may also be given the same reference symbol 231.

[0026] The material of the container body 4 is not particularly limited, and in this embodiment it is made of glass, but it may also be made of other materials, such as synthetic resin. From the viewpoint of improving the interior appearance and making it possible to visually check the remaining amount of chemical solution from the outside, the container 2 is preferably formed to be transparent (including translucent).

[0027] <2-2. Cover parts> As shown in Figures 3 and 4, the cover member 5 is attached to the container body 4 so as to cover the mouth 23 from above. The cover member 5 has a top surface 50, on which the opening S1 of the container 2 is formed. Figure 5 is a plan view of the cover member 5, and Figure 6 is a bottom view of the cover member 5. Note that Figure 4 corresponds to the C1-C1 cross-sectional view of Figure 5 and the C2-C2 cross-sectional view of Figure 6. The material of the cover member 5 is not particularly limited, and in this embodiment it is made of synthetic resin, particularly polypropylene, but it can also be made of other materials, for example, wood.

[0028] The top surface 50 includes a first surface 51 that surrounds the opening S1 from the outside and defines the opening S1, and a second surface 52 that surrounds the first surface 51 from the outside. The upper surface of the first surface 51 forms a slope that slopes upward radially outward. The upper surface of the first surface 51 is linear in a vertical cross-sectional view. The upper surface of the second surface 52 extends substantially horizontally. In the description of this embodiment, the terms "radial direction" and "circumferential direction" are defined with reference to an axis that passes through the center of the opening S1 and extends vertically, unless otherwise specified. In this embodiment, the opening S1 is approximately circular, and the outer shapes of the first surface 51 and the second surface 52 are also approximately circular in a plan view. Furthermore, in a plan view, the centers of the outer shapes of the opening S1, the first surface 51, and the second surface 52 all overlap the central axis of the mouth 23.

[0029] The cover member 5 also has a cylindrical wall portion 53 extending downward from the underside of the first surface portion 51. The wall portion 53 extends circumferentially downward from an inner peripheral edge portion 501 of the first surface portion 51 that defines the opening S1. In this embodiment, the outer shape of the wall portion 53 is also approximately circular in a plan view, and its center coincides with the opening S1. The outer diameter of the wall portion 53 is slightly smaller than the inner diameter of the mouth portion 23 of the container body 4. Therefore, the wall portion 53 is inserted into the mouth portion 23 while contacting the inner surface of the mouth portion 23 of the container body 4 or while being spaced slightly apart from the inner surface. The space inside the wall portion 53 is in communication with the opening S1, and the volatilizer 3 is inserted into this space.

[0030] The inner peripheral edge 501 of the first surface 51 is located radially inward from the upper end 231 of the mouth 23. The wall 53 includes a first portion 531 extending downward from the inner peripheral edge 501 along the inner surface of the mouth 23, and a second portion 532 extending further downward from the lower end of the first portion 531. As shown in FIG. 4 , the first portion 531 is in contact with or almost in contact with the inner surface of the container body 4 (the inner surface of the mouth 23), while the second portion 532 is spaced apart from the inner surface of the container body 4 to a certain extent. In this embodiment, the first portion 531 and the second portion 532 both extend in a substantially straight line in the vertical direction. However, because the inner surface of the container body 4 moves radially outward as it extends downward from the wall 53 at the position of the shoulder 22, a gap S2 between the second portion 532 and the inner surface of the container body 4 becomes larger than the gap between the first portion 531 and the inner surface of the container body 4. In addition, in this embodiment, the outer surface of the second portion 532 extends radially inward as it extends downward, and therefore the gap S2 becomes even larger than the gap between the first portion 531 and the inner surface of the container body 4. The gap S2 gradually becomes larger as it extends downward.

[0031] The cover member 5 also has multiple claws 54 extending downward from the underside of the top panel 50. These claws 54 are spaced radially outward from the wall 53 on the underside of the top panel 50 and arranged at predetermined intervals along the circumferential direction. While not limited to this, it is preferable that the claws 54 be arranged at equal intervals along the circumferential direction. Each claw 54 has a thin plate-like protruding piece 541 extending downward from the underside of the top panel 50 and a hooking portion 542 that is continuous with the lower end of the protruding piece 541 and bulges radially inward from the protruding piece 541. When attaching the cover member 5 to the container body 4, the mouth 23 of the container body 4 is inserted between the wall 53 and the claws 54. At this time, the hooking portion 542 climbs over the flange 231 of the mouth 23 due to elastic deformation of the protruding piece 541. Thereafter, the hook portion 542 and the flange portion 231 are hooked together, so that the connection between the cover member 5 and the container body 4 is maintained unless a strong external force is applied, and the two members 5 and 4 will not come off unintentionally. On the other hand, by intentionally applying a force in the vertical direction, the cover member 5 can be removed from the container body 4. The cover member 5 and the container body 4 are detachable.

[0032] The cover member 5 also has a cylindrical outer peripheral wall portion 55 extending downward from the peripheral edge of the top surface portion 50. The lower end of the outer peripheral wall portion 55 comes into contact with the upper surface of the lower step portion 221 of the shoulder portion 22 of the container body 4 when the cover member 5 is attached to the container body 4. In this embodiment, the top surface portion 50 and the body portion 21 of the cover member 5 have roughly the same outer shape in a plan view, and the container 2 has an overall cylindrical shape.

[0033] The top surface 50 forms a corner 57 at the inner peripheral edge 501 with which the volatilizer 3 inserted into the container 2 can come into contact. The corner 57 faces the opening S1 and extends circumferentially. The corner 57 is chamfered and rounded when viewed in vertical cross section of the top surface 50. In this embodiment, the volatilizer 3 can come into contact with the corner 57 when its lower end 3a is inserted into the recess in the peripheral edge 12 of the bottom surface 10 of the container body 4, in other words, when the volatilizer 3 is in a state where it is most inclined relative to the vertical direction within the container 2 (hereinafter referred to as the maximum inclination state).

[0034] However, some of the liquid medicine absorbed by the volatilizer 3, particularly along its outer surface, leaks onto and adheres to the top surface 50, primarily onto the first surface 51. If the liquid medicine leaked onto the first surface 51 remains on the first surface 51 and stains the top surface of the top surface 50, the appearance is not necessarily aesthetically pleasing. Furthermore, if the container 2 is overturned, the liquid medicine remaining on the first surface 51 may contaminate the surrounding environment. Furthermore, if a large amount of liquid medicine leaks from the volatilizer 3 due to environmental conditions such as ambient temperature and humidity, the liquid medicine may reach the second surface 52 from the first surface 51 and fall from the outer edge of the second surface 52, potentially contaminating the side of the container 2 and the surrounding environment. In response to this, the corner portions 57 facilitate the rapid return of the liquid medicine leaked onto the first surface 51 back into the container body 4. This makes it possible to prevent the chemical solution from contaminating the outer surface of the container 2 (including the upper surface of the top surface portion 50 and the side surface of the container 2) and the surrounding environment.

[0035] Specifically, the liquid medicine absorbed by the volatilizer 3 typically first collects on the top surface 50 near the corner 57 with which the volatilizer 3 comes into contact. If, as shown in FIG. 7A , corner 57' corresponding to corner 57 is not rounded in vertical cross section but forms a right angle, the space S3' defined by the volatilizer 3 and the area near corner 57' becomes wider. On the other hand, if corner 57 is rounded in vertical cross section as in this embodiment, the space S3 defined by the volatilizer 3 and the area near corner 57 becomes narrower, as shown in FIG. 7B . Such a narrowed space S3 tends to accumulate the liquid medicine at a high density, resulting in the formation of larger droplets, which become heavier and more likely to drop downward into the container body 4.

[0036] From the viewpoint of efficiently exerting the above-mentioned effects, the radius of curvature in the vertical cross section of the corner portion 57 at the point of contact between the volatilizer 3 in the maximum inclined state and the corner portion 57 is preferably 0.5 mm to 3.5 mm, more preferably 1 mm to 3 mm, and even more preferably 1.5 mm to 2.5 mm.

[0037] Furthermore, in this embodiment, since first surface 51 is inclined downward in the radially inward direction, the liquid medicine collected on first surface 51 tends to move by gravity on first surface 51 toward opening S1. Therefore, the liquid medicine can easily fall along wall 53 and return to container body 4.

[0038] The upper surface of first surface portion 51 may be configured to form an angle of 40° or less with respect to the horizontal. If the upper surface of first surface portion 51 approaches horizontal, it becomes difficult for the liquid medicine to return into container body 4 through opening S1. However, in this embodiment, corner portion 57 can promote the return of the liquid medicine, so it is also possible to make the upper surface of first surface portion 51 approach horizontal.

[0039] The wide gap S2 between the wall portion 53 and the inner surface of the container body 4 prevents the liquid medicine returning from the top surface 50 through the opening S1 into the container body 4 from leaking out of the container 2 again. In other words, if the wall portion 53 were not provided or if the second portion 532 of the wall portion 53 were omitted, the liquid medicine returning through the opening S1 into the container body 4 would leak out along the route indicated by the arrow A1 in FIG. 4 . In this case, the liquid medicine may rise through the narrow gap between the first portion 531 and the inner surface of the container body 4 due to capillary action, and then easily leak out along the mouth 23 and shoulder 22 of the container body 4. This problem may be exacerbated particularly when the gap between the upper end 231 of the mouth 23 and the top surface 50 is narrow or when the gap between the outer surface of the mouth 23 and the claw portion 54 is narrow. However, in this embodiment, the presence of the gap S2 prevents the chemical solution from reaching such a narrow gap as described above, reducing the risk of soiling the side surface of the container 2 and its surrounding environment.

[0040] <3. Modifications> 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. For example, the following modifications are possible. Furthermore, the gist of the following modifications can be combined as appropriate.

[0041] <3-1> In the above embodiment, the container 2 is composed of the container body 4 and the cover member 5. However, the present invention is also applicable to a case where the container does not have a cover member and has only the container body. In this case, the same effect can be achieved by applying to the container body a configuration similar to that of the top surface portion 50 (including the corner portions 57) of the cover member 5 described above.

[0042] <3-2> The configuration of the upper surface of the top surface portion 50 described above is merely an example, and various configurations are possible. For example, the first surface portion 51 forming the inclined surface may be omitted (see FIG. 8A), the upper surface of the first surface portion 51 may extend substantially horizontally (see FIG. 8B), or the inclined surface of the first surface portion 51 may be curved in a vertical cross-sectional view (see FIG. 8C). In the examples of FIGS. 8B and 8C, rounded corners 57 are formed in two locations with which the volatilizer 3 inserted into the container 2 can come into contact. The upper surface of the second surface portion 52 does not have to extend substantially horizontally, and may be inclined upward, particularly radially outward (see FIG. 8D). However, from the perspective of ensuring interior design, it is preferable that the upper surface of the second surface portion 52 extend substantially horizontally. From this perspective, the upper surface of second surface portion 52 preferably forms an angle of 40° or less with respect to the horizontal, more preferably an angle of 35° or less, even more preferably an angle of 30° or less, even more preferably an angle of 25° or less, even more preferably an angle of 20° or less, even more preferably an angle of 15° or less, and even more preferably an angle of 10° or less. Also, second surface portion 52 can be omitted (see FIG. 8E).

[0043] <3-3> In the above embodiment, wall portion 53 can be omitted (see FIG. 9A). Even in such a case, if inner peripheral edge portion 501 of top surface portion 50 of cover member 5 is positioned radially inward of upper end portion 231 of mouth portion 23, leakage of the medicinal solution to the outside through the gap between container body 4 and cover member 5 can be prevented.

[0044] The length of wall portion 53 can also be adjusted in various ways; for example, second portion 532 can be omitted (see FIG. 9B). In this case, in order for the medicinal liquid to leak to the outside through the gap between container body 4 and cover member 5, the medicinal liquid must rise against gravity between the outer surface of first portion 531 and the inner surface of mouth portion 23. Therefore, even in such a case, it is possible to prevent the medicinal liquid from leaking to the outside, although this is inferior to the above embodiment.

[0045] Furthermore, when the mouth 23 of the container body 4 is not cylindrical but is configured with a flat top surface, a wall 53 may be inserted into the mouth 23 (see FIG. 9C). Furthermore, in this case, the wall 53 may be inclined downward in the radially inward direction (see FIG. 9D). Even in such a case, if the lower end of the wall 53 is spaced apart from the inner surface of the container body 4, it is possible to prevent the medicinal solution from leaking to the outside through the gap between the container body 4 and the cover member 5. In the examples of FIGS. 9C and 9D, the lower end of the wall 53 extends below the lower surface of the mouth 23, which is the top surface. [Explanation of symbols]
