The present invention relates to a chemical vaporizer.

BACKGROUND ART Chemical liquid volatilizers have been known in which a rod-shaped volatilization body is inserted into a container containing a chemical liquid in such a manner that it projects from the inside of the container (for example, see Patent Documents 1 and 2). In this type of chemical volatilizer, the chemical liquid in the container is sucked up by the volatilization body and volatilized into the external space, thereby imparting the aromatic effect and other effects of the chemical liquid to the external space. In many cases, the volatile material is set so as to be inclined at an appropriate angle within the container in order to improve interior appearance.

By the way, in the chemical solution volatilizer as described above, when the remaining amount of the chemical solution becomes small, it may be difficult to check the remaining amount and it may be difficult to know when the chemical solution has been used up. In such a case, when the container is lifted to check the remaining amount, the volatile material moves within the container and the set angle of the volatile material is distorted. Moreover, when a plurality of volatilization bodies are used, their orientations are biased. After checking the remaining amount, if you touch the volatilization body to set it beautifully again in the container, your hands will become dirty with the chemical solution adhering to the volatilization body.

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

<1. Overall configuration of chemical vaporizer>
FIG. 1 shows a perspective view of a chemical vaporizer 1 according to an embodiment of the present invention. As shown in the figure, the chemical solution volatilization device 1 includes a container 2 in which a chemical solution is stored, and at least one rod-shaped volatilization body 3 inserted into the container 2. The container 2 has an opening S1 at the top, and the volatile material 3 is inserted into the container 2 through the opening S1. Note that "upper" and "lower" in this specification are defined based on the usage state shown in FIG. 1, unless otherwise specified.

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

The rod-shaped volatilization body 3 is inserted into the container 2 in such a manner that a portion thereof protrudes from the inside of the container 2. That is, the volatilization body 3 has a sufficient length relative to the height of the container 2, and is placed in the container in such a manner that the lower end 3a is placed inside the container 2 and the upper end 3b is exposed outside the container 2. It is inserted into 2. At this time, in order to improve the interior appearance of the chemical solution volatilization device 1, the volatilization body 3 is set in the container 2 in an inclined state with respect to the vertical direction. Moreover, as shown in FIG. 1, when a plurality of volatilization bodies 3 are used at the same time, these volatilization bodies 3 are set in the container 2 so as to face various directions and extend radially.

The volatile body 3 has a structure capable of sucking up the chemical liquid against gravity by capillary action, as will be described later. As a result, the chemical solution in the container 2 can rise along the volatilization body 3 from the lower end 3a to the upper end 3b, and volatilize (natural evaporation) from the outer surface of the volatilization body 3 into the external space. Thereby, the chemical liquid is diffused into the space around the chemical liquid volatilizer 1.

The shape and material of the volatilization body 3 are not particularly limited as long as the chemical liquid can be sucked up and volatilized to the outside. The volatile body 3 typically has an elongated, substantially cylindrical shape with micropores inside, and can be made of natural materials such as rattan, or synthetic resins such as polyethylene and polyacetal. You can also do it. The volatilization body 3 according to this embodiment has a cross-sectional shape shown in FIG. 2. In this example, the volatile body 3 is made of polyethylene terephthalate and polyurethane, and has a large number of irregularly shaped micropores 31 inside. Further, a large number of grooves 32 are formed on the outer surface of the volatilization body 3. These grooves 32 extend linearly along the axial direction of the volatilization body 3 from the lower end 3a to the upper end 3b. That is, the cross section of the volatilization body 3 does not have a smooth contour line along the circumferential direction, but has an uneven contour line. Further, these grooves 32 are arranged at approximately equal intervals along the circumferential direction of the volatilization body 3. The chemical solution is sucked up not only through the micropores 31 but also along the grooves 32 due to capillary action. Therefore, a large amount of chemical liquid tends to adhere to the outer surface of the volatile body 3 of this embodiment.

<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.

<2-1. Container body＞
The container body 4 has a bottom portion 10 . In this embodiment, the bottom portion 10 has a shape in which a peripheral portion 12 thereof is more depressed than a central portion 11 thereof. Therefore, when the remaining amount of the chemical solution in the container 2 becomes small, it accumulates in the depression of the peripheral edge part 12 of the bottom part 10. On the other hand, the lower end portion 3a of the rod-shaped volatilization body 3 is disposed at the peripheral edge portion 12 of the bottom surface portion 10 in many cases. Therefore, since the volatile body 3 and the chemical solution are configured to easily come into contact with each other, the chemical solution can be used up to the end.

The container body 4 includes a cylindrical body 21 that stands up from the bottom 10 along its outer periphery, a shoulder 22 continuous to the upper end of the body 21, and a neck 23 continuous to the upper end of the shoulder 22. has. Although not limited thereto, in the present embodiment, the outer shapes of the bottom surface portion 10, the body portion 21, the shoulder portions 22, and the neck portion 23 are all approximately circular in plan view, and their centers coincide. The neck portion 23 is a cylindrical portion that constitutes a mouth portion that communicates with the opening S1 at the top of the container 2. Hereinafter, the neck portion 23 will be referred to as a mouth portion, and may also be given the same reference numeral 23.

The mouth portion 23 has a smaller diameter than the body portion 21. Thereby, when the chemical solution volatilizer 1 falls down, the shoulder portion 22 becomes a wall, making it difficult for the chemical solution to spill through the opening S1. In particular, in this embodiment, since the mouth part 23 is arranged coaxially with the body part 21, the shoulder part 22 becomes a wall even if the chemical solution volatilizer 1 falls in any direction, and spilling of the chemical solution can be suppressed. Further, since the area of the cross section of the opening S1 is narrower than the area of the cross section of the body 21, the amount of the chemical liquid that naturally evaporates from the inside of the container 2 through the opening S1 is smaller than the amount of the chemical liquid stored in the container 2. The amount can be controlled.

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 plan view, the lower stage part 221 is arranged so as to surround the upper stage part 222 from the outside. Further, the upper end portion 231 of the mouth portion 23 is formed into a flange shape. Hereinafter, the upper end portion 231 will be referred to as a flange portion, and may also be given the same reference numeral 231.

The material of the container body 4 is not particularly limited, and in this embodiment, it is made of glass, but it may be made of other materials, such as synthetic resin. From the viewpoint of improving the interior appearance, the container 2 is preferably formed to be transparent (including translucent).

<2-2. Cover member＞
As shown in FIGS. 3 and 4, the cover member 5 is attached to the container body 4 so as to cover the mouth portion 23 from above. The cover member 5 has a top surface portion 50, and the opening S1 of the container 2 is formed in the top surface portion 50. 5 is a plan view of the cover member 5, and FIG. 6 is a bottom view of the cover member 5. Note that FIG. 4 corresponds to the C1-C1 sectional view in FIG. 5 and the C2-C2 sectional view in FIG. 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 may be made of other materials, such as wood.

The top surface section 50 includes a first surface section 51 that surrounds the opening S1 from the outside and defines the opening S1, and a second surface section 52 that surrounds the first surface section 51 from the outside. The upper surface of the first surface portion 51 forms a slope that slopes upward toward the outside in the radial direction. The upper surface of the first surface portion 51 is linear in a longitudinal cross-sectional view. The upper surface of the second surface portion 52 extends substantially in the horizontal direction. In the description of this embodiment, unless otherwise specified, "radial direction" and "circumferential direction" are defined based on an axis passing through the center of the opening S1 and extending in the vertical direction. In this embodiment, the opening S1 is substantially circular, and the outer shapes of the first surface portion 51 and the second surface portion 52 are also substantially circular in plan view. Further, in plan view, the centers of the outer shapes of the opening S1, the first surface portion 51, and the second surface portion 52 all overlap with the central axis of the mouth portion 23.

Further, the cover member 5 has a cylindrical wall portion 53 extending downward from the lower surface of the first surface portion 51. The wall portion 53 extends downward along the circumferential direction 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 plan view, and the center thereof 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 of the container body 4 while being in contact with the inner surface of the mouth portion 23 or at a slight distance from the inner surface. The space inside the wall portion 53 communicates with the opening S1, and the volatilization body 3 is inserted into the space.

The inner circumferential edge 501 of the first surface portion 51 is located radially inward than the upper end portion 231 of the mouth portion 23 . The wall portion 53 includes a first portion 531 that extends downward from the inner peripheral edge portion 501 along the inner surface of the mouth portion 23, and a second portion 532 that extends 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 portion 23), but the second portion 532 is They are separated by a certain distance. In this embodiment, the first portion 531 and the second portion 532 both extend in a substantially straight line in the vertical direction. However, as the inner surface of the container body 4 moves downward from the wall 53 at the shoulder portion 22, the gap S2 between the second portion 532 and the inner surface of the container body 4 becomes smaller than the first portion. The gap is larger than the gap between the portion 531 and the inner surface of the container body 4. Furthermore, in this embodiment, the outer surface of the second portion 532 moves radially inward as it goes downward, so the gap S2 becomes larger than the gap between the first portion 531 and the inner surface of the container body 4. The gap S2 gradually becomes larger toward the bottom.

Further, the cover member 5 has a plurality of claw portions 54 extending downward from the lower surface of the top surface portion 50. These claw portions 54 are arranged at predetermined intervals along the circumferential direction while being spaced radially outward from the wall portion 53 on the lower surface of the top surface portion 50 . Although not limited thereto, it is preferable that the claw portions 54 are arranged at equal intervals along the circumferential direction. Each claw portion 54 includes a thin plate-like protrusion piece 541 extending downward from the lower surface of the top surface portion 50, and a hook portion 542 that is continuous with the lower end of the protrusion piece 541 and bulges further inward in the radial direction than the protrusion piece 541. has. When attaching the cover member 5 to the container body 4, the mouth portion 23 of the container body 4 is inserted between the wall portion 53 and the claw portion 54. At this time, the hook portion 542 rides over the flange portion 231 of the mouth portion 23 due to the elastic deformation of the protrusion piece 541. Thereafter, as the hook portion 542 and the flange portion 231 are hooked together, the connection state between the cover member 5 and the container body 4 is maintained unless a strong external force is applied, and both members 5 and 4 are prevented from coming off unintentionally. There is no. On the other hand, the cover member 5 can be removed from the container body 4 by intentionally applying vertical force. The cover member 5 and the container body 4 are detachable.

Further, the cover member 5 has a cylindrical outer peripheral wall portion 55 extending downward from the peripheral edge of the top surface portion 50. The lower end portion 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 substantially the same outer shape in plan view, and the container 2 has a cylindrical shape as a whole.

A rib 56 extending along the circumferential direction is arranged on the first surface portion 51 of the top surface portion 50 so as to surround the opening S1 in the vicinity of the opening S1. In this embodiment, the rib 56 is arranged so as to substantially surround the entire circumference of the opening S1. A plurality of slits 561 are formed in the rib 56, and the rib 56 is interrupted at a plurality of locations along the circumferential direction due to these slits 561. The slits 561 are arranged at predetermined intervals along the circumferential direction, and although not limited thereto, it is preferable that the slits 561 are arranged at equal intervals along the circumferential direction.

The ribs 56 and slits 561 described above play the following roles. That is, a part of the chemical liquid sucked up by the volatilization body 3, particularly the chemical liquid sucked up along the outer surface thereof, leaks mainly onto the first surface part 51 of the top surface part 50 and adheres thereto. In this embodiment, since the first surface part 51 is inclined downwardly toward the inside in the radial direction, the chemical solution collected on the first surface part 51 moves on the first surface part 51 toward the opening S1 due to gravity. Moving. Thereafter, the drug solution falls along the wall portion 53 and is returned into the container body 4. Therefore, the surrounding environment is prevented from being contaminated by the chemical solution. On the other hand, the ribs 56 described above act to prevent the entire amount of the medicinal solution collected on the first surface portion 51 near the opening S1 from returning into the container body 4. In other words, the ribs 56 serve to store a portion of the chemical liquid on the first surface portion 51.

That is, due to the presence of the ribs 56, a liquid pool of the chemical liquid is formed on the top surface portion 50 at a position radially outward along the ribs 56, as shown by the dotted line in FIG. This liquid pool will normally be formed as long as the drug remains in the container body 4. Therefore, by visually confirming the presence of this liquid pool, the user can understand that the chemical liquid remains. On the other hand, by visually confirming that the liquid pool has disappeared, it is possible to understand when the chemical liquid has been used up. From the viewpoint of forming an easily visible liquid pool, the height of the rib 56 is preferably 0.5 mm or more, more preferably 0.7 mm or more, and even more preferably 1 mm or more. Further, from the same viewpoint, the length of the rib 56 is preferably 5 mm or more, more preferably 7 mm or more, and even more preferably 9 mm or more. The length of the rib 56 referred to here is the length along the rib 56 of the portion interrupted by the slit 561 (the length measured along the radially inner end). Further, the height of the rib 56 referred to herein is the height in the vertical vertical direction from the root position of the rib 56 on the upper surface of the first surface portion 51 to the upper end of the rib 56.

On the other hand, if a large amount of the chemical solution leaks from the volatile body 3 due to environmental conditions such as ambient temperature and humidity, the chemical solution reaches the second surface section 52 from the first surface section 51 and falls from the outer peripheral edge of the second surface section 52. , there is a risk of contaminating the side surface of the container 2 and the surrounding environment. From the viewpoint of preventing this problem, it is preferable that the upper surface of the first surface portion 51 extends to a position higher than the ribs 56. In addition, from the viewpoint of making it easier for the drug solution to get over the ribs 56 and return into the container body 4, the height of the ribs 56 is preferably 3 mm or less, more preferably 2 mm or less, and 1.5 mm or less. It is more preferable that it is the following.

The slit 561 also helps prevent similar problems. That is, the chemical solution can pass through the slit 561 and return into the container body 4 via the opening S1. Therefore, although a liquid pool is formed around the rib 56 as a sign that the chemical liquid remains, the slit 561 can prevent the chemical liquid from accumulating excessively on the top surface portion 50. From the viewpoint of making it easy for the drug solution to return into the container body 4, the width of the slit 561 is preferably 0.5 mm or more, more preferably 0.7 mm or more, and even more preferably 1 mm or more. preferable. Further, from the same viewpoint, the number of slits 561 is preferably one or more, more preferably two or more, and even more preferably four or more. On the other hand, from the viewpoint of forming an easily visible liquid pool, the width of the slit 561 is preferably 3 mm or less, more preferably 2 mm or less, and even more preferably 1.5 mm or less. Further, from the same viewpoint, the number of slits 561 is preferably 8 or less, more preferably 6 or less, and even more preferably 4 or less. Note that the width of the slit 561 here is the straight-line distance between the ribs 56 on both sides.

Moreover, the slit 561 also helps to fix the position of the volatilization body 3 because the volatilization body 3 is caught in the slit 561. Thereby, especially when a plurality of volatilization bodies 3 are used at the same time, it is possible to easily maintain a state in which these volatilization bodies 3 are not biased in the container 2 and extend radially in various directions. Further, when the volatilization body 3 is caught in the slit 561, the number of contact points between the volatilization body 3 and the rib 56 increases, so that the chemical solution can smoothly return into the container body 4 along the volatilization body 3. In addition, when the outer surface of the volatilization body 3 has an uneven shape as described above, it is preferable in that the volatilization body 3 is easily caught in the slit 561.

It is preferable that the number of volatile bodies 3 used at the same time is greater than the number of slits 561. In this case, at least one volatilized body 3 that is not caught in the slit 561 can be secured. That is, the chemical liquid sucked up by the volatilization body 3 usually gathers first near the position where the volatilization body 3 and the cover member 5 come into contact on the top surface portion 50 . At this time, if all the volatilized bodies 3 are caught in the slits 561, most of the chemical liquid will return into the container body 4 through the slits 561, and a sufficiently large liquid pool may not be formed. However, if there is volatile material 3 that is not caught in the slit 561, a sufficiently large liquid pool can be formed more reliably.

By the way, the wide gap S2 between the wall portion 53 and the inner surface of the container body 4 described above prevents the chemical solution from returning from the top surface portion 50 into the container body 4 through the opening S1 to leak out to the outside of the container 2 again. can be prevented. That is, if there is no wall portion 53 or the second portion 532 of the wall portion 53 is omitted, the chemical liquid that attempts to return into the container body 4 through the opening S1 will flow as indicated by the arrow A1 in FIG. There is a risk that it may leak outside through such a route. At this time, the drug solution can 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 move along the mouth 23 and shoulder 22 of the container body 4. may leak outside. In particular, this problem may be exacerbated if the gap between the upper end 231 of the mouth 23 and the top surface 50 is narrow, or if the gap between the outer surface of the mouth 23 and the claw 54 is narrow. However, in the present embodiment, the presence of the gap S2 allows the chemical solution to be prevented from reaching the narrow gap described here, reducing the risk of contaminating the side surface of the container 2 and its surrounding environment. Ru.

<3. Modified example>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit thereof. For example, the following changes are possible: Furthermore, the gist of the following modifications can be combined as appropriate.

<3-1>
In the above embodiment, the container 2 is composed of the container body 4 and the cover member 5, but the present invention is also applicable to a case where the container does not have a cover member and only has a container body. In this case, the same effect as that of the top surface portion 50 (including the ribs 56 and slits 561) of the cover member 5 described above can be applied to the container body.

<3-2>
In the above embodiment, the opening S1 has a substantially circular shape, but various shapes can be adopted. For example, it may be triangular or star-shaped as shown in FIGS. 7A to 7C, and in this case, the shape of the ribs 56 surrounding the opening S1 can be similarly changed. In this case, the position and number of slits 561 can also be set as appropriate.

<3-3>
In the embodiment described above, a plurality of slits 561 are formed in the rib 56, but the number of slits 561 may be one and the rib 56 may be interrupted at only one place. Furthermore, the ribs 56 may not be disconnected at all along the circumferential direction, and the slits 561 may be omitted.

<3-4>
The configuration of the upper surface of the top surface portion 50 described above is an example, and various configurations can be made. For example, the first surface portion 51 forming the slope may be omitted (see FIG. 8A), the upper surface of the first surface portion 51 may extend substantially horizontally (see FIG. 8B), or the first surface portion 51 may be omitted (see FIG. 8A). The slope 51 may be curved in a longitudinal cross-sectional view (see FIG. 8C). The upper surface of the second surface portion 52 may not extend substantially horizontally, but may be inclined upwardly, particularly radially outward (see FIG. 8D). However, from the viewpoint of ensuring interior design, it is preferable that the upper surface of the second surface portion 52 extends substantially horizontally. From this point of view, it is preferable that the second surface portion 52 forms an angle of 10° or less with respect to the horizontal direction. Moreover, the second surface portion 52 can also be omitted (see FIG. 8E).

<3-5>
In the embodiment described above, the wall portion 53 can be omitted (see FIG. 9A). Even in such a case, if the inner circumferential edge 501 of the top surface 50 of the cover member 5 is located radially inward than the upper end 231 of the mouth 23, the relationship between the container body 4 and the cover member 5 is It is possible to suppress leakage of the chemical liquid to the outside through the gap.

Furthermore, the length of the wall portion 53 can be adjusted variously, and for example, the second portion 532 can be omitted (see FIG. 9B). In this case, in order for the medicinal solution to leak to the outside through the gap between the container body 4 and the cover member 5, the medicinal solution must rise between the outer surface of the first portion 531 and the inner surface of the mouth portion 23 against gravity. There is a need to. Therefore, even in such a case, although it is inferior to the case of the above embodiment, it is possible to suppress leakage of the chemical liquid to the outside.

Moreover, when the mouth part 23 of the container main body 4 is not cylindrical but is composed of a flat top surface part, a wall part 53 may be inserted into the mouth part 23 (see FIG. 9C). Even in such a case, if the lower end of the wall portion 53 is separated from the inner surface of the container body 4, leakage of the chemical solution to the outside through the gap between the container body 4 and the cover member 5 can be suppressed. can do. In the example of FIG. 9C, the lower end of the wall portion 53 extends below the lower surface of the mouth portion 23, which is the top surface portion.
