Description

  The present invention relates to a volatilization apparatus that contains a liquid formulation having volatility and volatilizes active ingredients such as fragrances and deodorants contained in the liquid formulation in a space such as a room.

  Volatilization devices that volatilize liquid preparations containing fragrances, deodorants, etc. are mainly classified based on the arrangement direction of containers that contain liquid preparations, with the container opening facing upward during use The so-called upright installation type volatilization device installed in the above and the so-called inverted installation type volatilization device installed with the opening of the container facing downward when in use are included.

  As an example of an upright installation type volatilization device, a liquid absorbing member is inserted and arranged in a container containing a liquid preparation, and the liquid preparation (fragrance) is sucked up by the liquid absorbing member and exposed to the outside of the container. A liquid formulation (a container for fragrance) that volatilizes a liquid preparation from the top is known (see, for example, Patent Document 1).

Further, as an example of the inverted installation type volatilization device, the liquid holding member accommodated in the liquid holding member is arranged by bringing the opening of the inverted container into contact with the liquid holding member accommodated in the receiving tray part. A device (a volatilization apparatus) that is volatilized from a liquid is known (for example, see Patent Document 2).
Japanese Utility Model Publication No. 4-104854 (FIG. 1) Utility Model Registration No. 2605873 (page 3-4, Fig. 1)

  In the erecting volatilization device disclosed in Patent Document 1, a liquid absorbing member is inserted into the opening of the container, and the liquid preparation contained in the container is used by the liquid absorbing member to utilize the capillary phenomenon of the liquid absorbing member. Then, it is sucked up and volatilized from the filter paper-like member placed on the liquid absorbing member, but there is a limit to the height of liquid preparation sucked by the liquid absorbing member. In other words, the height at which the liquid absorbing member can be sucked up is limited to a height that balances the suction force due to the capillary phenomenon determined by the structure of the liquid absorbing member and the gravity acting on the liquid preparation that has been sucked up. Can't suck up on.

  By the way, the volatilization device installed indoors is usually sized to accommodate a liquid preparation in an amount that can be used continuously for a period of about one month. The container is being adopted. For example, even if the volatilization device is increased in capacity, the installation space, in other words, the projected area is difficult to increase, inevitably the height of the volatilization device is increased, and the length of the liquid absorbing member is accordingly increased. However, as described above, since there is a limit to the height that can be sucked by the liquid absorbing member, the volatilization apparatus cannot be increased in capacity sufficiently. Further, even if the volatilization device is enlarged within a range that satisfies the suckable height, there is a high possibility that the sucking force is reduced and the liquid preparation remains in the container by the length of the liquid absorbing member. Therefore, in the conventional volatilization apparatus, all the stored liquid preparations may not be used up.

  In the inverted installation type volatilization device disclosed in Patent Document 2 that solves this problem, the liquid retaining member is arranged in the tray, and the opening of the container that has been inverted is brought into contact with the liquid retaining member, An opening of the container is closed with the liquid level of the volatile liquid preparation soaked in the liquid retaining member to prevent the liquid preparation from overflowing. According to the inverted installation type volatilization apparatus having this configuration, there is a problem that the structure is complicated because the liquid retaining member must be prepared and arranged as a separate body outside the container for storing the liquid preparation. Further, when the container falls down, the contained liquid preparation may leak out, which is not practical and has room for improvement.

  The present invention has been made in view of the above-described circumstances, and the object thereof is to make it possible to sufficiently increase the capacity and to completely evaporate the stored liquid preparation without leaving any waste. It is to provide an economical volatilization device.

In order to achieve the above-described object, the volatilization apparatus according to the present invention is characterized by the following (1) and (2) .

(1) a container that contains a liquid preparation, has an opening in the center in plan view, and is placed with the opening facing upward;

(2) A liquid preparation storage chamber for storing the liquid preparation and a volatilization chamber having a bottom surface and an opening formed so as to be continuous with the bottom surface of the liquid preparation storage chamber are provided inside, and the opening is directed upward A container to be installed,
Volatilization means arranged in the container so as to contact the bottom surface of the liquid preparation storage chamber and the bottom surface of the volatilization chamber to isolate the liquid preparation storage chamber and the volatilization chamber,
With
The liquid preparation in the liquid preparation storage chamber is sucked up by the volatilization means, and volatilizes from the volatilization surface formed on the volatilization chamber side of the volatilization means through the volatilization chamber to the outside of the container from the opening. A volatilization device,
The height of the volatilization means is lower than the height at which the volatilization means can suck up the liquid preparation, and is lower than the liquid level of the liquid preparation in the container at the start of use of the volatilization apparatus ( (See FIG. 2).

According to the volatilization apparatus having the above configuration (1), the volatilization means can be shortened, and even if the volatilization apparatus is increased in capacity, the liquid preparation does not remain in the volatilization apparatus, and the volatilization means until the last drop. Can be sucked up and volatilized. Accordingly, the liquid preparation is not wasted and economical, and the replacement period of the volatilization apparatus can be extended to save the trouble of replacement, thereby providing an easy-to-use volatilization apparatus.
Similarly, according to the volatilization device having the configuration of (2) above, the volatilization means can be shortened, and even if the volatilization device is increased in capacity, the liquid preparation does not remain in the volatilization device, and the last drop. It can be sucked up by a volatilization means and volatilized. Accordingly, the liquid preparation is not wasted and economical, and the replacement period of the volatilization apparatus can be extended to save the trouble of replacement, thereby providing an easy- to-use volatilization apparatus .

  According to the present invention, since a large amount of liquid preparation contained in a large-capacity volatilization apparatus can be volatilized by a relatively short volatilization means, the liquid preparation can be volatilized efficiently and used up to the last drop. Can be used. Further, according to the present invention, the volatilization apparatus can be increased in capacity without increasing the occupied installation area, and can be used over a long period of time.

  The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading through the best mode for carrying out the invention described below with reference to the accompanying drawings.

Hereinafter, a plurality of preferred embodiments according to the present invention will be described in detail with reference to the drawings. A first reference example will be described before the description of the embodiment.

( First Reference Example )
FIG. 1 is a longitudinal sectional view of a volatilization apparatus 100 which is a first reference example of the present invention. As shown in FIG. 1, the volatilization apparatus 100 is a so-called upright installation type volatilization apparatus that is installed with the opening of the container facing upward at the time of use. And a liquid member 13. In the present specification, the upper direction to which the opening is directed is defined to include the upper side in the vertical line direction and the diagonally upper side, and is arbitrary as long as the implementation of the present invention is not hindered.

  The container 11 is a container made of, for example, a synthetic resin, and has two upper surfaces formed at different levels, ie, a first upper surface 11a having a low height and a second upper surface 11b having a high height. It is formed in a substantially L-shaped cross section. The first upper surface 11a is provided with an opening 11c that opens upward.

  The inner bottom surface of the bottom wall of the container 11 will be described in detail. The first bottom surface 11d aligned in the vertical direction of the first upper surface 11a and the container 11 is the lowest, and the second upper surface 11b and the vertical direction of the container 11 are in the vertical direction. The second bottom surface 11e formed continuously from the first bottom surface 11d is inclined so as to gradually increase as the distance from the first bottom surface 11d increases.

  The outer bottom surface of the bottom wall of the container 11 that is located on the opposite side of the second bottom surface 11e has a surface that extends flush with the outer bottom surface of the bottom wall of the container 11 that is located on the opposite side of the first bottom surface 11d. The leg portion 11f is provided so as to protrude downward, and the container 11 can be installed on the installation surface without rattling.

  The container 11 constitutes one space surrounded by the first upper surface 11a, the second upper surface 11b, the first bottom surface 11d, the second bottom surface 11e, and the peripheral wall 11g, and the liquid preparation 15 is accommodated in the space. Yes. As a material for forming the container 11, any of plastic, paper, metal, ceramic, glass, and the like can be used as long as the liquid preparation 15 does not leak.

  The active ingredients contained in the liquid preparation 15 include fragrance ingredients, deodorant ingredients, antibacterial ingredients, bactericidal ingredients, repellent ingredients, fungicidal ingredients, fungicidal ingredients, rust preventing ingredients, insecticide ingredients, pyrethroid insecticide ingredients, organophosphorus Examples thereof include a system insecticidal component, a carbamate insecticidal component, an oxadiazole insecticidal component, an insect growth regulating component, and the like, but the liquid preparation 15 contains at least one active ingredient. Examples of aromatic components include essential oil components such as peppermint oil, peppermint oil, spearmint oil, rush, cypress, citronella, citral, citronellal, lemon, lemongrass, orange, eucalyptus, lavender, and the like and aromatic components obtained therefrom. be able to. Examples of the deodorant component include lauryl methacrylate, methylated cyclodextrin, plant extract (for example, an extract obtained from camellia, rose, chrysanthemum, pine, cedar, plantain, etc.), plant essential oil (for example, tea Extracts, catechins, plant polyphenols, linalool, menthol, borneol, etc.), surfactants, and the like.

  When the liquid formulation 15 contains both a fragrance component and a deodorant component, the total amount of the fragrance component and the deodorant component in the liquid formulation 15 is generally 0.5 to It is 10% by weight, preferably 1 to 5% by weight. In addition, liquid formulation 15 includes hydrogenated castor oil, glycerin or a derivative thereof, fatty acid or a derivative thereof, alcohol, a polyhydric alcohol or a derivative thereof, a surfactant (for example, sodium alkyl sulfate, polyoxyethylene fatty acid ester) , Etc.), pigments such as tar pigments and bengara, preservatives such as preservatives, etc. The content of these other additives in the liquid preparation 15 is generally 10% by weight or less. The liquid preparation 15 may further contain a chelating agent, a viscosity adjusting agent, a specific gravity adjusting agent, an ultraviolet ray preventing agent, an antioxidant, and the like. In the liquid preparation 15, the above components can be appropriately adjusted using water, alcohol, an organic solvent, or the like.

  Further, an additive for preventing the liquid preparation 15 from remaining in the liquid-absorbing member 13 can be added to the liquid preparation 15, and examples of this type of additive include BHT, BHA, Examples include ascorbic acid, tocopherol, and erythorbic acid. The additive can be blended in the liquid absorbing member 13 as well as the liquid preparation 15 as long as it is a necessary amount (about 0.2% to 5% of the total liquid composition to be obtained). As the liquid preparation 15, water, an aqueous solution, a solution, or the like can be used as a liquid which is heated and evaporated as necessary. Further, an aqueous or oily stabilizer may be blended.

  The liquid absorbing member 13 is disposed by being inserted into the container 11 from the opening 11c provided in the first upper surface 11a having a low height, and one end 13a abuts on the first bottom surface 11d of the container 11, The other end is exposed to the outside of the container 11 to form a volatilization surface 13b.

  The liquid-absorbing member 13 is a rod-shaped member that absorbs the liquid preparation 15, and sucks up the liquid preparation 15 accommodated in the container 11 according to the principle of capillary action and volatilizes it from the volatilization surface 13 b to the outside. Any member can be used as the liquid absorbing member 13 as long as it has performance suitable for heating or non-heated volatilization capable of absorbing liquid, and can be used as inorganic powder, organic powder, inorganic fiber, organic fiber. , Etc., which are made of at least one kind of material and blended with a binder and consolidated or sintered. As described above, the material for forming the liquid absorbing member 13 may be either an inorganic material or an organic material, but is preferably a resin, specifically, polyethylene terephthalate (hereinafter, also referred to as PET), acrylic resin ( Hereinafter, it is also referred to as PA), and one or more of polypropylene and polyethylene can be mentioned. In particular, the liquid-absorbing member 13 preferably has a characteristic that allows gas-liquid exchange. Here, the liquid-absorbing member having the property of exchanging gas and liquid means that the liquid preparation 15 in the container 11 penetrates into the liquid-absorbing member and is volatilized outside the container 11 and from the outside of the container 11. It means a liquid-absorbing member having such a characteristic that a gas such as air penetrates into the liquid-absorbing member and is discharged outside the liquid-absorbing member inside the container 11. The liquid-absorbing member having the property of allowing gas-liquid exchange is preferably a porous material, for example, a porous material using PET or PA. Further, the porosity, the cross-sectional size, etc. of the liquid-absorbing member having the property of allowing gas-liquid exchange can be appropriately set according to various conditions such as the amount of the liquid preparation 15 inside the container 11 and the viscosity of the liquid preparation 15. It is preferable to do. In the case of using a liquid absorbing member having a property capable of exchanging gas and liquid as the liquid absorbing member 13, it is preferable that the liquid absorbing member 13 usually has a porosity of 20% or more, more preferably a porosity of 20 to 80%, More preferably, it is preferable to have 30 to 80%.

  As the volatilization means, in addition to the liquid absorbing member 13 described above, a porous body, a microporous sheet to be described later, and the like can be used, and in particular, as long as the liquid preparation 15 can be volatilized through these. It is not limited.

  The liquid absorbing member 13 includes an ultraviolet ray inhibitor, a pyrethroid insecticide, an organic phosphorus insecticide, a carbamate insecticide, an oxadiazole insecticide, a fragrance, an antioxidant, a flame retardant (for example, water), Add any kind and required amount of additives such as flame retardants, bactericides, fungicides, pigments, binders, hydrophilic solvents, amphiphilic liquids, surfactants, etc. as long as they do not interfere with the implementation. Is also possible.

  The height H1 of the liquid absorbing member 13 is equal to or lower than the height at which the liquid preparation 15 can be sucked up, and is lower than the liquid level height H2 of the liquid preparation 15 stored in the container 11 at the start of use. The suckable height is a height determined by the material, density, hydrophilicity, the size of the gap between the materials, the viscosity, specific gravity, etc. of the liquid preparation 15. In order to volatilize the liquid preparation 15 stably, the height H1 of the liquid absorbing member 13 is generally about 1.5 cm to 7.5 cm, but may be about 1 cm if there is no problem with volatilization. Further, the diameter or width of the liquid absorbing member 13 is arbitrary as long as practicable. The height H1 of the liquid absorbing member 13 shown in FIG. 1 and the liquid level height H2 of the liquid preparation 15 at the start of use are both the height from the installation surface including the thickness of the bottom wall of the container 11. It is needless to say that the relationship is the same even if the height is from the first bottom surface 11d (that is, the inner bottom surface) of the container 11.

The operation of the first reference example will be described. As shown in FIG. 1, the volatilization apparatus 100 is installed with the opening 11 c facing upward, that is, in an upright state. Since the liquid level height H2 of the liquid preparation 15 is higher than the height H1 of the liquid absorption member 13 at the start of use, the liquid level height H2 of the liquid preparation 15 and the liquid level height H2 are absorbed on the volatilization surface 13b of the liquid absorption member 13. Since the liquid pressure of the difference H3 (H3 = H2-H1) with respect to the height H1 of the liquid member 13 is acting, the liquid preparation 15 oozes out from the volatilization surface 13b of the liquid absorption member 13 and volatilizes outside. As time passes, the liquid level H2 of the liquid preparation 15 gradually decreases, and the liquid pressure acting on the volatilization surface 13b becomes zero when it reaches the same height as the height H1 of the liquid absorbing member 13.

  When the liquid surface height H2 of the liquid preparation 15 is further lowered to a position (height H4) indicated by an imaginary line L in FIG. 1, the liquid absorbing member 13 has the height H1 of the liquid absorbing member 13 and the liquid preparation 15. The liquid preparation 15 was sucked up by the difference H5 (H5 = H1-H4) in the liquid level height H4 and volatilized from the volatilization surface 13b.

  When there is almost no remaining liquid preparation 15, the liquid preparation 15 on the second bottom surface 11e moves from the inclined second bottom surface 11e to the first bottom surface 11d. In other words, all the liquid preparations 15 gather on the first bottom surface 11d arranged so that the one end 13a of the liquid absorbing member 13 contacts, and from one end 13a of the liquid absorbing member 13 that contacts the first bottom surface 11d. It is sucked up and volatilizes from the volatilization surface 13b. As a result, the liquid preparation 15 is sucked up to the last drop without any waste and is volatilized and acts effectively. Further, even if the capacity of the volatilization device 100 is increased, the height (length) of the liquid absorbing member 13 can be set to the same level as the conventional one, so that the installation area of the volatilization device 100 is not increased, That is, the volatilization device 100 can be increased in capacity by increasing the height of the volatilization device 100 to a height at which the liquid formulation 15 cannot be sucked up by the liquid absorbing member 13 in the conventional form.

The configuration of the first reference example will be briefly described as follows.
A container 11 (that is, a container) that contains the liquid preparation 15, has an opening 11 c, and is installed with the opening 11 c facing upward;
One end 13a inserted into the housing 11 from the opening 11c and disposed in the housing 11 so as to contact the first bottom surface 11d of the housing 11 (that is, the inner bottom surface) and the housing 11 A liquid-absorbing member 13 (that is, a volatilization means) having the other end arranged so as to be exposed to the outside,
With
The liquid preparation 15 in the container 11 is a volatilization device 100 that is sucked up by the liquid absorption member 13 and volatilized from a volatilization surface 13b formed at the other end of the liquid absorption member 13,
The height H1 of the liquid absorbing member 13 is equal to or lower than the height at which the liquid absorbing member 13 can suck up the liquid preparation 15 and the liquid preparation 15 in the container 11 at the start of use of the volatilization device 100. The surface height is lower than H2.

  According to the volatilization apparatus 100, one end 13a of the volatilization means (liquid absorbing member) 13 inserted into the container 11 from the opening 11c of the container 11 that is installed with the opening 11c facing upward and accommodates the liquid preparation 15. Is in contact with the bottom surface 11d of the container 11 and a volatilized surface 13b formed at the other end is disposed so as to be exposed to the outside of the container 11. The liquid preparation 15 accommodated in the container 11 is sucked up by the volatilization means 13 and volatilized to the outside from the volatilization surface 13b.

  The height H1 of the volatilization means 13 is lower than the height at which the volatilization means 13 can suck up the liquid preparation 15, and is lower than the liquid level height H2 of the liquid preparation 15 accommodated in the container 11 at the start of use. Yes. Thereby, the volatilization means 13 can be shortened, and even if the volatilization apparatus 100 is increased in capacity, the liquid preparation 15 does not remain in the container 11, and the last drop is sucked up and volatilized by the volatilization means 13. Can do. Therefore, the liquid preparation 15 is not wasted and economical, and the replacement period of the volatilization apparatus 100 can be extended to save the trouble of replacement, and the volatilization apparatus 100 that is easy to use can be provided.

The storage chamber 33 and the volatilization chamber 31 are separated by the liquid absorbing member 23. Moreover, the liquid level height H2 of the liquid preparation 15 at the start of use is higher than the height (length) H1 of the liquid absorbing member 23. Note that the height H1 of the liquid absorbing member 23 shown in FIG. 2 and the liquid level height H2 of the liquid preparation 15 at the start of use both include the thickness of the bottom wall of the container 21 and the height from the installation surface. It is needless to say that the relationship is the same even if the height is from the bottom surface 25b (that is, the inner bottom surface) of the container 21.

The other end is exposed to the concave portion 37 from the through hole 35b to form a volatilization surface 13b. The liquid preparation 15 is accommodated in the container 35, and the height H2 of the liquid preparation 15 at the start of use is higher than the height H1 of the liquid absorbing member 13. Note that the height H1 of the liquid absorbing member 13 shown in FIG. 3 and the liquid level height H2 of the liquid preparation 15 at the start of use both include the thickness of the bottom wall of the container 35 and the height from the installation surface. It is needless to say that the relationship is the same even if the height is from the bottom surface 35c (that is, the inner bottom surface) of the container 35.

  In the volatilization apparatus 300 having such a configuration, since the liquid absorbing member 13 is disposed in the substantially V-shaped recess 37, the height H1 of the liquid absorbing member 13 is reduced even if the container 35 has a large capacity. Thus, the performance of sucking up the liquid preparation 15 can be improved. Further, since the shape of the container 35 is an inverted trapezoid, the capacity of the container 35 can be increased without increasing the installation area, and the container 35 can be stably installed.

Other operations and effects of the second embodiment can be easily inferred from the first reference example and the above description of the first embodiment, and thus the description thereof is omitted.

  In addition, regarding the shape of the container 35, the substantially square V-shaped recess 37 is provided with side walls (not shown) at both ends in the depth direction in FIG. It is good also as an inverted cone shape which rotated the wall surrounding the circumference | surroundings centering on the axial center of the through-hole 35b. Accordingly, the concave portion 37 is caused to function as a liquid reservoir portion, and even if the liquid preparation 15 having an amount greater than or equal to the volatilization amount is sucked up from the liquid absorbing member 13, it is temporarily stored in the liquid reservoir portion (recess portion 37). And the outflow to the outside is prevented.

  In addition, since the lower-end peripheral part of the annular wall of the container 35 which forms the through-hole 35b and fits in the liquid absorption member 13 is extended below toward the bottom face 35c of the container 35, the said annular shape Compared with the case where the area of the wall in contact with the liquid-absorbing member 13 is smaller (in other words, the length of the annular wall is shorter), the liquid-absorbing member 13 has a smaller contact area with the liquid preparation 15 and thus absorbs more water. Excessive supply of the liquid formulation 15 to the liquid member 13 is prevented, and leakage of the liquid formulation 15 is prevented.

  Further, the volatilization device 300, when not in use, inverts the volatilization device 300 upside down to temporarily stop the supply of the liquid preparation 15 to the liquid absorbing member 13, and when in use, the volatilization device 300 is again installed upright. By volatilizing, the liquid formulation 15 can be efficiently used by volatilizing only when necessary.

The configuration of the second embodiment will be briefly described as follows.
A container 35 (that is, a container) that contains the liquid preparation 15, has a through hole 35 b (that is, an opening), and is installed with the through hole 35 b facing upward;
One end 13a that is inserted into the housing body 35 through the through hole 35b and is disposed in the housing body 35 so as to contact the bottom surface 35c (ie, the inner bottom surface) of the housing body 35, and the outside of the housing body 35. A liquid absorbing member 13 (that is, a volatilization means) having the other end disposed so as to be exposed to
With
The liquid preparation 15 in the container 35 is a volatilization apparatus 300 that is sucked up by the liquid absorption member 13 and volatilized from a volatilization surface 13b formed at the other end of the liquid absorption member 13,
The height H1 of the liquid absorbing member 13 is equal to or lower than the height at which the liquid absorbing member 13 can suck up the liquid preparation 15 and the liquid preparation 15 in the container 35 at the start of use of the volatilization apparatus 300. The surface height is lower than H2.

( Third embodiment)
Next, 3rd Embodiment of the volatilization apparatus of this invention is described. FIG. 4 is a longitudinal sectional view of a volatilization apparatus 400 according to the third embodiment of the present invention.

As shown in FIG. 4, the volatilization apparatus 400 is a so-called upright installation type volatilization apparatus that is installed with the opening of the container facing upward at the time of use. And a liquid member 13. The third embodiment has a portion common to the second embodiment many, as different parts, since only the structure of the housing body 41, portions which are common with the second embodiment are the same The reference numerals are attached for clarification, and the description is simplified or omitted.

  The container 41 is a semi-cylindrical container having a substantially U-shaped cross section formed of a synthetic resin, and an upper surface recess 41b having a substantially U-shaped cross section is formed on the upper surface 41a. A through hole 41 c centering on a vertical line VL passing through the center of gravity G of the container 41 is provided in the upper surface recess 41 b. The liquid absorbing member 13 is inserted into the through hole 41c, one end 13a of which is in contact with the bottom surface 41d which is the arcuate inner bottom surface of the container 41, and the other end is exposed to the outside through the through hole 41c so Forming. The liquid preparation 15 is stored in the container 41, and the liquid level height H2 of the liquid preparation 15 at the start of use is higher than the height H1 of the liquid absorbing member 13. Note that the height H1 of the liquid-absorbing member 13 shown in FIG. 4 and the liquid level height H2 of the liquid preparation 15 at the start of use are both the height from the installation surface including the thickness of the bottom wall of the container 41. It is needless to say that even if the height is from the bottom surface 41d (that is, the inner bottom surface) of the container 41, the relationship is the same.

  When the liquid preparation 15 is volatilized and the remaining amount decreases, the liquid preparation 15 gathers at the lowermost part along the arc-shaped bottom surface 41d, is sucked up from one end 13a of the liquid absorbing member 13, and volatilizes from the volatilization surface 13b. Thereby, the liquid formulation 15 is volatilized without waste until the last drop and can be used effectively. Moreover, since the outer bottom surface located on the opposite side of the bottom surface 41d in the bottom wall of the container 41 has an arc shape, the container 41 is swung by the applied vibration or the like, so that the liquid preparation 15 is absorbed into the liquid absorbing member. 13 is wetted and sucked up efficiently and volatilized. Furthermore, the swinging container 41 can be installed indoors as a pleasant decorative accessory.

  In the volatilization apparatus 400 having such a configuration, since the liquid absorbing member 13 is arranged in the upper surface concave portion 41b having a substantially U-shaped cross section, the height H1 of the liquid absorbing member 13 is reduced even if the container 41 has a large capacity. It is possible to improve the suction performance of the liquid preparation 15. Further, since the shape of the container 41 is a semi-cylindrical shape having a substantially U-shaped cross section, the capacity of the container 41 can be increased without increasing the installation area.

Other operations and effects of the third embodiment can be easily inferred from the above description of the first reference example , the first embodiment, and the second embodiment, and thus the description thereof is omitted.

  The shape of the container 41 is not limited to a semicylindrical shape, and may be a hemispherical shape. In this case, the container 41 can swing in any direction, and the function as a decorative accessory is enhanced. Further, in this case, since the upper surface recess 41b becomes a bowl-shaped depression that functions as a liquid reservoir, even if an amount of the liquid preparation 15 larger than the volatilization amount is sucked up from the liquid-absorbing member 13, it temporarily becomes a depression. It is possible to store it, and the outflow to the outside is prevented.

  Further, the volatilization device 400, when not in use, inverts the volatilization device 400 upside down to temporarily stop the supply of the liquid preparation 15 to the liquid absorbing member 13, and when in use, the volatilization device 400 is again installed upright. By volatilizing, the liquid formulation 15 can be efficiently used by volatilizing only when necessary.

The configuration of the third embodiment will be briefly described as follows.
A container 41 (that is, a container) that contains the liquid preparation 15, has a through hole 41 c (that is, an opening), and is installed with the through hole 41 c facing upward;
One end 13a disposed in the housing 41 so as to be inserted into the housing 41 through the through hole 41c and in contact with the bottom surface 41d (that is, the inner bottom surface) of the housing 41, and the outside of the housing 41 A liquid absorbing member 13 (that is, a volatilization means) having the other end disposed so as to be exposed to
With
The liquid preparation 15 in the container 41 is a volatilization device 400 that is sucked up by the liquid absorbing member 13 and volatilized from a volatilization surface 13b formed at the other end of the liquid absorbing member 13,
The height H1 of the liquid absorbing member 13 is equal to or lower than the height at which the liquid absorbing member 13 can suck up the liquid preparation 15, and the liquid formulation 15 in the container 41 at the start of use of the volatilization device 400. The surface height is lower than H2.

( Fourth embodiment)
Next, 4th Embodiment of the volatilization apparatus of this invention is described. FIG. 5 is a longitudinal sectional view of a volatilization apparatus 500 according to the fourth embodiment of the present invention.

  As shown in FIG. 5, the volatilization device 500 is a so-called upright volatilization device that is installed with the opening of the container facing upward when in use. And a liquid member 53. The container 51 is a container having a substantially U-shaped cross section formed of a synthetic resin. The container 51 is continuously formed upward from the lower part 51b of the container and the lower part 51b of the container, and the opening 51f of the container 51. And an upper portion 51c of the accommodation chamber continuously extending to one side so as to be positioned above. A partition wall 51d is formed in the lower portion 51b of the storage chamber, thereby providing an independent liquid absorption member storage chamber 55, in which the liquid absorption member 53 is stored. A small-diameter hole 51e extending along the bottom surface 51a of the container 51 is formed in the partition wall 51d so that the lower part 51b of the storage chamber communicates with the liquid absorbing member storage chamber 55. In addition, the liquid absorbing member accommodation chamber 55 is provided with an opening 51f opened upward.

  In order to limit the excessive supply of the liquid preparation 15 to the liquid absorbing member 53, it is desirable that the small diameter hole 51e has an infinitely small diameter or an infinitely narrow slit hole. In FIG. 5, the partition wall 51d is provided so as to protrude into the lower portion 51b of the storage chamber. However, the left side wall of the lower portion 51b of the storage chamber extends downward as it is, and extends into the lower portion 51b of the storage chamber. Needless to say, the shape may have no shape.

The liquid absorbing member 53 is manufactured in the same manner as the liquid absorbing member of the first reference example, the first embodiment to the third embodiment, and is formed in a flat plate shape that is different only in shape. The size of the liquid absorbing member 53 is set slightly larger than the size of the liquid absorbing member accommodation chamber 55. The liquid absorbing member 53 is inserted from the opening 51f and pushed into the liquid absorbing member accommodation chamber 55, and is placed in a horizontal state so as to eliminate a gap between the liquid absorbing member 53 and the opening 51f. Yes. Thereby, the liquid formulation 15 accommodated in the container 51 does not leak from the opening 51f. One end of the liquid absorbing member 53 is disposed so as to contact the bottom surface 51a of the container 51, and the other end (volatilization surface) of the liquid absorbing member 53 is disposed so as to be exposed to the outside of the container 51 from the opening 51f. Yes.

  Since the liquid absorbing member 53 is disposed at the lowermost part in the container 51, the height H1 of the liquid absorbing member 53 is lower than the liquid level height H2 of the liquid preparation 15 at the start of use. Accordingly, the entire amount of the liquid preparation 15 can be soaked into the liquid absorbing member 53 and volatilized, and the liquid preparation 15 does not remain in the container 51. Moreover, unlike the conventional volatilization apparatus, it is not necessary to arrange a volatilization sheet separately from the volatilization apparatus, and handling becomes easy. Note that the height H1 of the liquid absorbing member 53 shown in FIG. 5 and the liquid level height H2 of the liquid preparation 15 at the start of use both include the thickness of the bottom wall of the container 51 and the height from the installation surface. It is needless to say that even if the height from the inner bottom surface of the container 51 is the same, the relationship is the same.

Since the other parts of the fourth embodiment are the same as those of the first reference example , the same parts are denoted by the same or corresponding reference numerals, and the description thereof is omitted. Further, since the other operations and effects of the fourth embodiment can be easily inferred from the above description of the first reference example , the first embodiment, the second embodiment, and the third embodiment, the description is omitted. .

  In addition, a microporous sheet (not shown) is provided so as to cover the opening 51f instead of the liquid absorbing member 53, and the liquid preparation 15 in the liquid absorbing member accommodation chamber 55 is volatilized to the outside through the microporous sheet. You can also

In the present specification, the microporous sheet is defined as a sheet-like member (a sheet or a film or the like) in which a large number of extremely fine holes that allow passage of gas but prevent passage of liquid are formed. The microporous sheets of the second reference example and the third reference example are sheet-like members having similar characteristics.

  Further, the volatilization device 500, when not in use, inverts the volatilization device 500 upside down to temporarily stop the supply of the liquid preparation 15 to the liquid absorbing member 53, and when in use, the volatilization device 500 is installed upright again. By volatilizing, the liquid formulation 15 can be efficiently used by volatilizing only when necessary.

The configuration of the fifth embodiment will be briefly described as follows.
A container 51 (that is, a container) that contains the liquid preparation 15, has an opening 51f, and is installed with the opening 51f facing upward;
Inserted into the housing 51 through the opening 51f and disposed at one end disposed in the housing 51 so as to contact the bottom surface 51a (that is, the inner bottom surface) of the housing 51 and outside the housing 51. A liquid absorbing member 53 (that is, a volatilization means) having the other end arranged to be exposed;
With
The liquid preparation 15 in the container 51 is a volatilization device 500 that is sucked up by the liquid absorbing member 53 and volatilized from a volatilization surface formed at the other end of the liquid absorbing member 53,
The height H1 of the liquid absorbing member 53 is equal to or lower than the height at which the liquid absorbing member 53 can suck up the liquid preparation 15, and the liquid formulation 15 in the container 51 at the start of use of the volatilization device 500. The surface height is lower than H2.

( Second reference example)
Next, a second reference example of the volatilization apparatus of the present invention will be described. FIG. 6 is a longitudinal sectional view of a volatilization apparatus 600 which is a second reference example of the present invention.

  The volatilization apparatus 600 is a so-called inverted installation type volatilization apparatus that is installed with the opening of the container facing downward during use, and includes a container 61 and a microporous sheet 63 that is a volatilization means. . The container 61 is a cylindrical container formed of a synthetic resin for containing the liquid preparation 15, and a lid body 61 a that is an example of a load reducing mechanism is fixed to the opening of the container 61 and is integrally formed. ing. A plurality of small-diameter through holes 61b are formed in the lid 61a. Further, at least three leg portions 61c are provided so as to protrude downward from the lid body 61a, whereby the lid body 61a is separated from the installation surface 65 of the volatilization device 600 and formed between the leg portions 61c. The through hole 61b communicates with the outside of the volatilization apparatus 600 through the created space.

  The microporous sheet 63 is a sheet-like member in which a number of extremely fine holes that allow gas to pass but prevent the passage of liquid are formed. The microporous sheet 63 is disposed inside the lid body 61a and covers the through hole 61b. ing. The microporous sheet 63 is fixed to the lid body 61a so that there is no gap between the outer periphery and the outer periphery of the microporous sheet 63, so that the liquid preparation 15 leaks from the outer periphery of the microporous sheet 63. It is preventing. In addition, about the liquid formulation 15, it shall refer to the said description of 1st Embodiment and abbreviate | omits description.

  The microporous sheet 63 is subjected to a load (hydraulic pressure) due to the liquid preparation 15 accommodated in the container 61, but the microporous sheet 63 is supported by a lid body 61a provided with a through hole 61b. A part of the load (hydraulic pressure) by the liquid preparation 15 is received by the lid 61a, and even if a large amount of the liquid preparation 15 is accommodated in the container 61, there is no possibility of damaging the microporous sheet 63 due to its weight. Therefore, the volatilization apparatus 600 can be increased in capacity.

  The volatilization device 600 is installed in an inverted state with the through hole 61b facing down during use, and the liquid preparation 15 is accommodated above the microporous sheet 63. Therefore, the microporous sheet 63 is always in the liquid preparation 15 during use. The liquid preparation 15 is always in contact with the microporous sheet 63. Accordingly, the entire amount of the liquid preparation 15 accommodated in the container 61 is volatilized through the microporous sheet 63 and released to the outside. At this time, the opening of the container 61 is sealed by the microporous sheet 63 and therefore does not leak. Moreover, since the volatilization apparatus 600 of this form does not need to use the suction-type liquid absorbing member described in the first to fifth embodiments, the structure is simplified, and all the liquid preparation 15 can be volatilized. .

  Further, when the volatilization apparatus 600 is not used, the volatilization apparatus 600 is turned upside down so that the microporous sheet 63 and the liquid preparation 15 are temporarily brought into contact with each other and the liquid preparation 15 is supplied to the microporous sheet 63. And the volatilization device 600 is inverted and volatilized again at the time of use, so that the liquid preparation 15 can be efficiently used by volatilizing only when necessary.

  The volatilization apparatus 600 is not limited to the installation type, and for example, a hanging tool (not shown) is arranged on the upper portion of the container 61 or a part of the peripheral wall and hung on an indoor wall or the like. It may be. Alternatively, instead of providing the leg portion 61c, a support leg (not shown) that can be installed by tilting the volatilization device 600 is provided on a part of the peripheral wall of the container 61, and the lid 61a that is tilted and opened to the outside. It is also possible to volatilize from.

The configuration of the second reference example will be briefly described as follows.
A container 61 (that is, a container) having an opening and containing the liquid preparation 15; and a microporous sheet 63 provided in the opening so as to close the opening, and the container is in use. A volatilization apparatus 600 in which the container 61 is installed with the opening of 61 facing downward, and the liquid preparation 15 is volatilized from the microporous sheet 63 to the outside of the container 61,
Furthermore, a lid 61a having a plurality of through holes 61b, which is attached to the container 61 so as to cover the microporous sheet 63, is provided.
The microporous sheet 63 on which the liquid pressure of the liquid preparation 15 acts is disposed so as to be in close contact with the surface of the lid 61a on the container 61 side so as to be supported by the lid 61a.
That is, the microporous sheet 63 is provided with a load reducing mechanism (that is, a lid 61a) that reduces the load applied to the microporous sheet 63 by the liquid pressure of the liquid preparation 15.

  According to the volatilization apparatus 600, the lid 61a in which a plurality of through holes 61b are formed is attached to the opening of a container (container) 61 that accommodates the liquid preparation 15. A microporous sheet 63 is disposed in close contact with the inner side of the lid 61a. When the container 61 is placed with the opening (that is, the lid 61a) facing downward when in use, the liquid preparation 15 is microporous. By volatilizing from the sheet 63 to the outside, the liquid pressure of the liquid preparation 15 is received by the lid 61a, and the microporous sheet 63 can be prevented from being damaged by the liquid pressure of the liquid preparation 15 acting on the microporous sheet 63. . Therefore, it is not necessary to use volatilization means such as a liquid absorbing member, and the liquid preparation 15 can be used up to the end with a simple mechanism. An opening / closing lid that can be opened and closed is provided at the top of the container 61 so that the liquid preparation 15 can be replenished, and the lid 61a described here may be integrally formed to be the bottom of the container 61. Needless to say.

( Third reference example)
Next, the 3rd reference example of the volatilization apparatus of this invention is demonstrated. FIG. 7 is a longitudinal sectional view of a volatilization apparatus 700 which is a third reference example of the present invention.

  The volatilization apparatus 700 is a so-called inverted installation type volatilization apparatus that is installed with the opening of the container facing downward when in use, and includes a container 71 and a microporous sheet 63 that is a volatilization means. . The container 71 is a cylindrical container made of synthetic resin in which a ring-shaped protrusion 71b having an opening 71a is formed in the lower part of the inner peripheral surface, and the microporous sheet 63 extends over the entire periphery of the ring-shaped protrusion 71b. It is fixed. On the inner side of the microporous sheet 63 of the container 71, a ring plate-shaped first support part 71c formed on the inner peripheral surface of the container 71, and a plurality of legs 71d standing from the first support part 71c. A disc-shaped second support portion 71e is provided which is connected to the first support portion 71c and disposed above the first support portion 71c.

  A supply amount limiting sheet 73, which is a supply amount limiting means, is fixed between the first support portion 71c and the second support portion 71e by adhesion or the like. The first support portion 71c, the second support portion 71e, and the supply amount limiting sheet 73 constitute a load reducing mechanism. The supply amount limiting sheet 73 is a sheet-like member that allows the liquid formulation 15 that is smaller than the volatilization amount of the liquid formulation 15 that volatilizes from the microporous sheet 63 to pass, and the liquid formulation 15 is accommodated above the load reducing mechanism when used. Therefore, the microporous sheet 63 is always lower than the liquid level of the liquid preparation 15.

  Thereby, the liquid preparation 15 accommodated in the container 71 is supplied dropwise from the supply amount limiting sheet 73 to the microporous sheet 63 little by little, and is volatilized in the microporous sheet 63 and volatilized outside. The supply amount limiting sheet 73 that is a supply amount limiting means supplies the liquid preparation 15 in an amount smaller than the volatilization amount of the liquid preparation 15 volatilized from the microporous sheet 63 to the microporous sheet 63. It does not become one that accumulates on the microporous sheet 63, and therefore, a large hydraulic pressure does not act.

Since the other parts of the third reference example are the same as those of the second reference example, the same parts are denoted by the same or corresponding reference numerals, and description thereof is omitted. Further, the other operations and effects of the third reference example can be easily inferred from the above description of the second reference example, and thus the description thereof is omitted. In addition, the liquid formulation 15 is also referred to the above description of the first reference example , and the description is omitted.

  Further, when not in use, the volatilization apparatus 700 is configured such that the volatilization apparatus 700 is erected upside down and the supply amount limiting sheet 73 and the liquid preparation 15 are temporarily brought into non-contact with the liquid preparation 15 with respect to the microporous sheet 63. When the supply is stopped and the volatilization device 700 is inverted and volatilized again at the time of use, the liquid preparation 15 can be efficiently used by volatilizing only when necessary.

The configuration of the third reference example will be briefly described as follows.
A container 71 (that is, a container) that has an opening and accommodates the liquid preparation 15; and a microporous sheet 63 provided in the opening so as to close the opening, and the container is in use. 71 is a volatilization device 700 in which the container 71 is installed with the opening of 71 facing downward, and the liquid preparation 15 is volatilized from the microporous sheet 63 to the outside of the container 71,
Furthermore, a load reduction mechanism (that is, the first support portion 71c, the second support portion 71e, and the supply amount limiting sheet 73) that reduces the load applied to the microporous sheet 63 by the liquid pressure of the liquid preparation 15 is provided. .
More specifically, the volatilization device 700 is disposed above the microporous sheet 63 of the container 71 in use so as to partition the interior of the container 71, and the container 71 is separated from the microporous sheet 63. A supply amount limiting means (that is, a supply amount limiting sheet) 73 that permeates the liquid formulation 15 that is less than the volatilization amount of the liquid formulation 15 that volatilizes outside and supplies the liquid formulation 15 to the microporous sheet 63;
The supply amount limiting means 73 is configured so that a partial load of the liquid preparation 15 in the container 71 is applied to the microporous sheet 63.

  According to the volatilization apparatus 700, the microporous sheet 63 is disposed in the opening 71 a of the container (container) 71 that stores the liquid preparation 15, and is volatilized from the microporous sheet 63 inside the container 71 of the microporous sheet 63. Since the supply amount limiting means (supply amount limiting sheet) 73 for supplying the liquid formulation 15 in an amount smaller than the volatilization amount of the liquid formulation 15 to be supplied to the microporous sheet 63 is provided, the liquid formulation 15 is supplied in small amounts. It is supplied from the restricting means 73 to the microporous sheet 63 and volatilized. Thereby, the liquid pressure of the whole liquid preparation 15 accommodated in the container 71 does not act directly on the microporous sheet 63, and the microporous sheet 63 can be prevented from being damaged by the liquid pressure. Moreover, since the liquid formulation 15 is supplied to the microporous sheet 63 little by little, the usage period can be extended.

  The supply amount limiting means is not limited to the supply amount limiting sheet 73, and any means can be used as long as it can supply a liquid preparation 15 in an amount smaller than the volatilization amount of the liquid preparation 15 volatilized from the microporous sheet 63. For example, instead of the plurality of leg portions 71d, the first support portion 71c and the second support portion 71e are closed with an annular side wall continuous over the entire circumference, Supply amount limiting means by providing a small hole or a gap through which the liquid preparation 15 less than the volatilization amount from the microporous sheet 63 is passed through any of the first support portion 71c, the second support portion 71e, or the annular side wall. It is good.

The volatilization apparatus 700 is not limited to the installation type, like the volatilization apparatus 600 of the second reference example. For example, a hanging tool (not shown) is arranged on the upper portion of the container 71 or a part of the peripheral wall. Then, it may be used by hanging on an indoor wall or the like. Alternatively, a support leg (not shown) that can be installed by tilting the volatilization device 700 is provided on a part of the peripheral wall of the container 71 and is volatilized from the microporous sheet 63 that is tilted and opened to the outside. Is also possible.

(4th reference example)
Next, a fourth reference example of the volatilization apparatus of the present invention will be described. FIG. 8 is a longitudinal sectional view of a volatilization apparatus 800 which is a fourth reference example of the present invention.

  The volatilization apparatus 800 is a so-called upright installation type volatilization apparatus that is installed with the opening of the container facing upward at the time of use. The container 81, the on-off valve 83, and the liquid absorbing member 13 that is a volatilization means. And. The container 81 is a container formed of a synthetic resin, and is divided in a vertical direction by a partition wall 81 a and is provided with two storage chambers, an upper storage chamber 85 and a lower storage chamber 87. The volume of the lower storage chamber 87 is much larger than the volume of the upper storage chamber 85 and can store a large amount of the liquid preparation 15. A through hole 81c opened upward is formed on the upper surface 81b of the upper storage chamber 85, and the liquid absorbing member 13 formed in a rod shape is inserted therein. One end 13a of the liquid absorbing member 13 contacts the bottom surface of the upper storage chamber 85, in other words, the upper surface of the partition wall 81a, and the other end is exposed to the outside of the upper storage chamber 85 from the through hole 81c to form a volatilization surface 13b. Yes.

  The on-off valve 83 is composed of a valve seat 81d formed as a conical hole in the partition wall 81a and having a valve hole 81e, and a ball 89 that is a valve body that opens and closes the valve hole 81e while being in contact with the valve seat 81d. When the volatilization device 800 is installed in an upright state (in other words, when the upper storage chamber 85 is installed upward), the ball 89 comes into contact with the valve seat 81d by gravity and closes the valve hole 81e. Further, the ball 89 is connected to the valve seat 81d by using a flexible body such as a string so that the ball 89 is not separated from the valve seat 81d so that the ball 89 does not sit on the valve seat 81d. The movement range of 89 may be limited. As a result, the ball 89 can be reliably brought into contact with the valve seat 81d to close the valve hole 81e.

  The volatilization apparatus 800 is configured as described above. In use, the volatilization apparatus 800 is first accommodated in the lower accommodation chamber 87 by opening the valve hole 81e by separating the ball 89 from the valve seat 81d by turning the container 81 upside down. A part of the liquid preparation 15 is moved to the upper storage chamber 85. Then, the container 81 is rotated again to assume an upright posture in the normal installation direction. As a result, the ball 89 comes into contact with the valve seat 81d and the on-off valve 83 is closed. And the liquid formulation 15 accommodated in the upper accommodating chamber 85 is sucked up by the liquid absorbing member 13 and volatilized to the outside from the volatilization surface 13b.

  The height H1 of the liquid absorbing member 13 may be low (short) even if the volatilization apparatus 800 has a large capacity, as long as the liquid preparation 15 in the relatively shallow upper storage chamber 85 can be sucked up. The liquid formulation 15 can be efficiently sucked up and volatilized. Note that the height H1 of the liquid absorbing member 13 shown in FIG. 8 and the liquid level height H2 of the liquid preparation 15 in the upper storage chamber 85 both include the thickness of the partition wall 81a of the container 81. Although represented by the height from the lower surface, the height H1 of the liquid-absorbing member 13 is higher than the liquid surface height H2 of the liquid preparation 15 even when the height is from the upper surface of the partition wall 81a. Although this point is different from the first to fifth embodiments (that is, FIGS. 1 to 5) described above, the volatilization device 800 has a height H <b> 1 of the liquid absorbing member 13 in the lower housing chamber 87. It is preferable because a large amount of liquid preparation 15 having a higher liquid level can be accommodated. The length of the liquid-absorbing member 13 itself is shorter than the liquid level of the liquid preparation 15 in the lower storage chamber 87 when the volatilization device 800 is used.

Since the other parts of the fourth reference example are the same as those of the first reference example , the same parts are denoted by the same or corresponding reference numerals, and the description thereof is omitted. Further, other actions and effects of the fourth reference example can be easily inferred from the above description of the first reference example , the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment. Therefore, explanation is omitted.

The configuration of the fourth reference example will be briefly described as follows.
A container 81 (that is, a container) that contains the liquid preparation 15;
The interior of the container 81 is vertically divided so that an upper storage chamber 85 and a lower storage chamber 87 for storing the liquid preparation 15 are formed in the container 81, and the upper storage chamber 85 and A partition wall 81a having a valve seat 81d having a valve hole 81e for communicating with the lower housing chamber 87;
A through hole 81c (that is, an opening) formed on the upper housing chamber 85 side of the housing body 81 so as to communicate the upper housing chamber 85 with the outside of the housing body 81;
A ball 89 (that is, a valve body) that is located in the upper storage chamber 85 and that opens and closes the valve hole 81e in contact with the valve seat 81d;
One end 13a inserted into the housing 81 through the through hole 81c and disposed in the upper housing chamber 85 so as to contact the surface of the partition 81a on the upper housing chamber 85 side, and the outside of the housing 81 A liquid-absorbing member 13 (that is, a volatilization means) having the other end on which the volatilization surface 13b is formed and disposed so as to be exposed to
A volatilization apparatus 800 comprising:
When used, the container 81 is turned upside down, the ball 89 is separated from the valve seat 81d to open the valve hole 81e, and a part of the liquid preparation 15 accommodated in the lower accommodating chamber 87 is removed from the upper part. After moving to the storage chamber 85, the container 81 is turned upside down again to be in an upright posture, and the liquid preparation 15 stored in the upper storage chamber 85 is sucked up by the liquid absorbing member 13 and the volatilized surface. 13b is volatilized to the outside of the container 81.

According to the volatilization apparatus 800 of the fourth reference example, two storage chambers 85 and 87 are formed that are divided into upper and lower portions by a partition wall 81 a having an on-off valve 83 and store the liquid preparation 15. Means (liquid absorbing member) 13 is provided. One end 13a of the volatilization means (liquid absorbing member) 13 is in contact with the bottom surface of the partition wall 81a, and the volatilization surface 13b formed at the other end is disposed to be exposed to the outside from the opening 81c of the upper storage chamber 85. In use, the volatilization device 800 is turned upside down and a part of the liquid formulation 15 accommodated in the lower accommodation chamber 87 is moved to the upper accommodation chamber 85, and then the volatilization device 800 is returned to the upright posture to accommodate the upper portion. The liquid preparation 15 accommodated in the chamber 85 is sucked up by the volatilization means 13 and volatilized to the outside from the volatilization surface 13b.

  Accordingly, each time the required amount of the liquid preparation 15 is used, the liquid preparation 15 can be moved from the lower storage chamber 87 to the upper storage chamber 85 to divide and volatilize the liquid preparation 15 by volume. Can be stripped. In addition, since a large amount of the liquid preparation 15 is stored in the lower storage chamber 87 and a part thereof is moved to the small upper storage chamber 85 and volatilized, the volatilization unit 13 can be reduced in size and the length of the volatilization unit can be reduced. It can be shortened and can be volatilized efficiently.
