Japanese Patent Application Laid-Open No. 2003-220125

In the volatilization device disclosed in Patent Document 1, the top surface of the columnar volatilization carrier and the bottom surface of the columnar absorbent material are in contact with each other. When the upper surface of the volatilization carrier and the lower surface of the absorbent material are in sufficient contact, the supply of the liquid formulation from the absorbent material to the volatilization carrier is stable, so the liquid formulation is consumed at a stable rate. be.

However, since the volatilization carrier, the absorbent material, and the like are industrial products, individual differences may occur. Depending on the degree of individual differences in the volatilization carrier and the liquid absorbing material, the upper surface of the volatilization carrier and the lower surface of the liquid absorbing material may not be in sufficient contact (for example, the liquid absorbing material may slightly contact the volatilization carrier). Inclining, the carrier for volatilization and the absorbent material come into point or line contact.). In such a case, the supply of the liquid preparation from the absorbent material to the volatilization carrier may not be stable, and the consumption rate of the liquid preparation may not be stable.

The present invention has been made to solve such problems, and its object is to enable liquid preparations to be consumed at a relatively stable rate even when individual differences occur in each member. It is to provide a volatilization device.

A volatilization device according to the present invention includes a bottle and a volatilization body. The bottle is configured to contain a liquid formulation comprising an active ingredient and includes a supply configured to downwardly dispense the liquid formulation. The volatilization body is arranged below the bottle and configured to volatilize into the air the active ingredient of the liquid formulation supplied through the supply section. The feed section and the volatilizer are configured to engage with each other.

This volatilization device is configured such that the supply portion of the bottle and the volatilization body are engaged with each other. Therefore, for example, even if some individual differences occur in the bottle and the volatilization body, the supply part and the volatilization body sufficiently contact each other at the position where the supply part of the bottle and the volatilization body engage. As a result, according to this volatilization device, the liquid preparation can be consumed at a relatively stable rate even if there are some individual differences between the bottle and the volatilization body. In addition, when the user installs the bottle and the volatilization body by himself/herself before starting use, the supply part and the volatilization body may be misaligned. Since the misalignment at the time of attachment is absorbed by joining, the supply part and the volatilization body can be brought into sufficient contact with each other.

In the volatilization device, an opening is formed below the bottle, the supply part is a liquid-absorbing material attached to the opening, and the liquid-absorbing material is configured to absorb the liquid preparation. In addition, it protrudes downward from the lower end of the opening, and a recess is formed in the upper part of the volatilization body. may engage.

In this volatilization device, the concave portion formed in the upper portion of the volatilization body and the absorbent material engage with each other. Therefore, even if there are some individual differences between the bottle and the volatilization body, the liquid absorption material and the volatilization body are in sufficient contact at the position where the liquid absorption material and the volatilization body engage. As a result, according to this volatilization device, the liquid preparation can be consumed at a relatively stable rate even if there are some individual differences between the bottle and the volatilization body.

According to the present invention, it is possible to provide a volatilization device capable of consuming a liquid preparation at a relatively stable rate even when individual differences occur in each member.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The same or corresponding parts in the drawings are denoted by the same reference numerals, and the description thereof will not be repeated.

[1. Overview of volatilization device]
FIG. 1 is an exploded view of volatilization device 10 according to this embodiment. As shown in FIG. 1 , volatilization device 10 includes bottle 100 , lower container 200 , and volatilization body 300 . Bottle 100 contains a liquid preparation (eg, fragrance or deodorant). The liquid preparation contained in the bottle 100 is supplied to the volatilization body 300 contained in the lower container 200. The active ingredient of the liquid preparation is volatilized in the volatilization body 300 , and the volatilized active ingredient is diffused to the outside of the lower container 200 . Thereby, for example, when the liquid formulation is a fragrance, an aromatic effect can be obtained, and when the liquid formulation is a deodorant, for example, a deodorizing effect can be obtained.

[2. Configuration of volatilization device]
FIG. 2 is a schematic diagram showing a cross section of volatilization device 10 according to the present embodiment. As shown in FIG. 2 , the volatilization body 300 is accommodated inside the lower container 200 , and the bottle 100 is arranged above the lower container 200 . That is, each of lower container 200 and volatilization body 300 is arranged below bottle 100 .

Bottle 100 is configured to contain liquid formulation 110 . Liquid formulation 110 is, for example, a fragrance or deodorant, as described above. When liquid formulation 110 is a fragrance, the active ingredient of liquid formulation 110 is the fragrance ingredient. Examples of aromatic components include essential oil components such as rush, cypress, citronella, citral, citronellal, lemon, lemongrass, orange, eucalyptus and lavender, peppermint oil, peppermint oil, spearmint oil, and aromatic components obtained therefrom. can be mentioned. Moreover, when the liquid preparation 110 is a deodorant, the active ingredient of the liquid preparation 110 is a deodorizing ingredient. Deodorizing ingredients include, for example, lauryl methacrylate, methylated cyclodextrin, plant extracts (for example, extracts obtained from camellia, rose, chrysanthemum, pine, cedar, and plantain), plant essential oils (for example, tea extract, catechin , plant polyphenols, linalool, menthol, borneol), surfactants.

An opening O1 is formed at the bottom of the bottle 100, and a liquid-absorbing wick 120 (liquid-absorbing material) is engaged with the opening O1. The liquid absorbent wick 120 protrudes downward from the lower end of the opening O1. Although the shape is not particularly limited, the opening O1 has a circular shape in a plan view, and the absorbent wick 120 has a columnar shape. The liquid absorbent wick 120 is configured to absorb the liquid preparation 110 and perform gas-liquid exchange. Examples of materials for the absorbent core 120 include polyethylene terephthalate, acrylic resin, polypropylene, and polyethylene. In addition, the material of the liquid absorbent core 120 is not limited to these, and any material that allows gas-liquid exchange can be used.

The volatilization body 300 is configured to volatilize the active ingredient of the liquid preparation 110 supplied through the liquid absorbent core 120 into the air. Examples of materials for the volatilization body 300 include porous materials such as resin, pulp, nonwoven fabric, and glass. In addition, the material of the volatilization body 300 is not limited to these, and any material may be used as long as it can volatilize the active ingredient of the liquid preparation 110 .

FIG. 3 is a development view of the volatilization body 300. FIG. As shown in FIG. 3, the volatilization body 300 is plate-shaped and cross-shaped in the developed state. Volatilization body 300 includes a top surface 310 and side surfaces 320 , 330 , 340 , 350 . Volatile body 300 is formed by bending each of side surfaces 320, 330, 340, 350 downward relative to top surface 310 and extends downward relative to top surface 310 (FIG. 1). A concave portion 315 is formed in the upper surface 310 . By extending downward, the liquid formulation 110 is carried downward by gravity. Therefore, the non-volatile components of the liquid formulation 110 are less likely to deposit on the upper sides of the sides, which are close to the pores and tend to dry, and clogging is less likely to occur. As a result, the volatilization of fragrance is less likely to be impaired even in the latter period of use. The depth of the concave portion 315 is not particularly limited, but the deeper the concave portion, the larger the contact area between the volatilization body 300 and the absorbent core 120, so that the liquid preparation 110 can be consumed at a stable rate. Furthermore, the height of the entire product can be reduced.

Referring to FIG. 2 again, in the volatilization device 10, the concave portion 315 of the volatilization body 300 and the absorbent core 120 of the bottle 100 are engaged. The reason why the concave portion 315 and the absorbent wick 120 are engaged with each other in the volatilization device 10 will be described below.

FIG. 4 is a diagram showing a cross section of volatilization body 600 in a hypothetical case. As shown in FIG. 4, in this hypothetical example, the upper surface of volatilization body 600 and the lower surface of absorbent core 120 are in contact. When the upper surface of the volatilization body 600 and the lower surface of the liquid absorbent core 120 are in sufficient contact, the supply of the liquid preparation 110 from the liquid absorption core 120 to the volatilization body 600 is stable, so the liquid preparation 110 is stabilized. Consumed at speed.

However, since the volatilization body 600, the absorbent core 120, and the like are industrial products, individual differences may occur. Depending on the degree of individual differences in the volatilization body 600 and the absorbent core 120, etc., the upper surface of the volatilization body 600 and the lower surface of the absorbent core 120 may not sufficiently contact each other (for example, the liquid absorbent core 120 may is slightly inclined, and the volatilization body 600 and the absorbent core 120 are in point or line contact.). In such a case, the supply of the liquid preparation 110 from the absorbent core 120 to the volatilization body 600 may not be stable, and the consumption rate of the liquid preparation 110 may not be stable.

FIG. 5 is a diagram showing a cross section of volatilization body 300 in the present embodiment. As shown in FIG. 5 , in the present embodiment, liquid absorbent wick 120 is fitted in concave portion 315 of volatilization body 300 . As a result, in addition to the lower surface of the absorbent core 120 , the side surfaces also come into contact with the vaporizer 300 . Since the contact area between the volatilizing body 300 and the liquid absorbing core 120 is wider than in the above hypothetical example, even if there are some individual differences between the liquid absorbing core 120 and the volatilizing body 300, etc., the liquid absorbing core 120 Liquid preparation 110 is stably supplied to volatilization body 300 . As a result, the volatilization device 10 can consume the liquid formulation 110 at a relatively stable rate.

Referring to FIG. 2 again, lower container 200 is configured to accommodate volatilization body 300 as described above. A plurality of holes H1 are formed in the side surface of the lower container 200 . The active ingredient (of the liquid preparation 110) volatilized in the volatilization body 300 is diffused to the outside of the lower container 200 through the plurality of holes H1. At least a portion of upper surface 310 of volatilization body 300 (for example, a portion other than recessed portion 315) is located higher than the lower ends of the lowest holes H1. At least part of the position where the liquid preparation 110 spreads in the volatilization body 300 is located higher than the lower end of the lowest hole H1, so that the area where the volatilization body 300 and the hole H1 face each other is secured to some extent. As a result, according to the volatilization device 10, even if the active ingredient contained in the liquid preparation 110 is heavier than the air, the active ingredient can be sufficiently diffused from the holes H1. Incidentally, the concave portion 315 may also be positioned higher than the lower end of the lowest hole H1. In this case, the entire upper surface 310 of the volatilization body 300 is positioned higher than the lower ends of the lowest holes H1, so that the active ingredient of the liquid preparation 110 can more effectively diffuse through the holes H1. Further, if the entire upper surface 310 is higher than the middle point of the upper end and the lower end of the lowest hole H1, the volatilization body can increase the area facing the hole and efficiently volatilize, which is preferable.

[3. feature]
As described above, in volatilization device 10 according to the present embodiment, absorbent core 120 (supply portion) of bottle 100 and volatilization body 300 are configured to engage with each other. Therefore, even if there is some individual difference between the bottle 100 and the volatilization body 300, the liquid absorption core 120 and the volatilization body 300 are sufficiently in contact with each other at the position where the liquid absorption core 120 and the volatilization body 300 are engaged. As a result, the volatilization device 10 can consume the liquid preparation 110 at a relatively stable rate even if there are some individual differences between the bottle 100 and the volatilization body 300 .

[4. Modification]
Although the embodiments have been described above, the present invention is not limited to the above embodiments, and various modifications are possible without departing from the scope of the invention. Modifications will be described below.

<4-1>
FIG. 6 is a schematic diagram showing a cross section of a volatilization device 10A according to a modification. As shown in FIG. 6, the volatilization device 10A includes a bottle 100A and a volatilization body 300A. A guide portion 125 forming an opening O1 is provided below the bottle 100A. The guide portion 125 is a cylindrical member. The inside of the guide portion 125 is filled with the absorbent wick 120A.

315 A of convex parts are formed in 310 A of upper surfaces of 300 A of volatilization bodies. A portion (upper portion) of the convex portion 315A is inserted below the guide portion 125 . That is, in this modified example, the volatilization body 300A and the liquid absorbent wick 120A are in contact with each other while the convex portion 315A and the guide portion 125 are engaged.

In this case, only the upper surface of the convex portion 315A and the lower surface of the absorbent wick 120A are in contact with each other. However, since the protrusions 315A and the liquid absorbent core 120A are guided by the guide section 125, the liquid absorbent core 120A is unlikely to be tilted with respect to the protrusions 315A. Therefore, in the volatilization device 10A, there is a high possibility that the lower surface of the liquid absorbent wick 120A and the upper surface of the convex portion 315A are in sufficient contact with each other. As a result, according to the volatilization device 10A, the liquid preparation 110 can be consumed at a relatively stable rate even if there are some individual differences between the bottle 100A and the volatilization body 300A.

In this modified example, the bottle 100A is an example of the "bottle" in the present invention, and the structure composed of the guide portion 125 and the liquid absorbent core 120A is an example of the "supply portion" in the present invention.

Moreover, in the above embodiment, the volatilization body 300 has the shape shown in FIG. However, the shape of volatilization body 300 is not limited to this, and may be any shape as long as it has an upper surface capable of forming concave portion 315 . For example, in volatilization body 300, upper surface 310 was square, but upper surface 310 may have a triangular shape. In this case, three side surfaces are connected to the top surface 310 . Moreover, the volatilization body 300 may be cross-shaped, for example.

FIG. 7 is a diagram showing an example of a cross-shaped volatilization body 300B. As shown in FIG. 7, volatilization body 300B is formed by crossing two plate-like volatilization bodies. A concave portion 315B is formed in the upper portion of the volatilization body 300B. The liquid absorbent wick 120 is engaged with the concave portion 315B. Moreover, the volatilization body 300 may be cylindrical, for example.

FIG. 8 is a diagram showing an example of a columnar volatilization body 300C. As shown in FIG. 8, the volatilization body 300C is formed by molding the volatilization body into a cylindrical shape. 315 C of recessed parts are formed in the upper surface of 300 C of volatilization bodies. The absorbent wick 120 is engaged with the recess 315C.
