  The lower container 12 forms a lower half of a substantially rectangular parallelepiped portion of the main body of the inverted volatilization device 10. The lower container 12 has a plurality of volatilization openings 15 formed on the entire circumference of the side portion.

As shown in FIG. 2, the bottle 11 has an engaging portion 17 that is fitted to a locking projection 16 formed on the lower container 12 on the outer peripheral portion near the lower end portion. Further, an opening 18 is formed at the lower end of the bottle 11, and the opening 18 is closed by an inner plug 20 fitted with a liquid absorbent core 19. Moreover, the upper part of the bottle 11 is formed with a shape that imitates a flower so as to improve the appearance decoration.
In addition, in order to seal the liquid absorption core 19 before use of the inverted volatilization apparatus 10, the cap 21 shown with a virtual line in FIG. Various materials such as metal and plastic can be used for the inner plug 20, for example. When using metal, it is necessary to prevent leakage by using packing or the like. In addition, any resin may be used as long as it is made of plastic, and polyethylene is preferable from the viewpoint of economical efficiency and usability, and this polyethylene is not particularly limited. It may be a single unit of density polyethylene, branched low density polyethylene or a mixture thereof. The mixing ratio is arbitrary. Furthermore, a plasticizer is added as necessary. This is to increase productivity.

  The liquid absorption core 19 is a liquid absorption member that absorbs the liquid preparation 13. The material for forming the liquid absorbent core 19 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 also referred to as PA). 1), or two or more of polypropylene and polyethylene. In particular, the liquid absorbent core 19 preferably has a characteristic that allows gas-liquid exchange. Here, the liquid-absorbing wick having the property of exchanging gas and liquid means that the liquid preparation 13 in the bottle 11 penetrates into the liquid-absorbent wick and is discharged to the outside of the bottle 11, and the air from the bottle 11 outside. It means a liquid absorbent core having a characteristic that gas penetrates into the liquid absorbent core and is discharged inside the bottle 11 to the outside of the liquid absorbent core. The liquid-absorbing core having the property of exchanging gas and liquid is preferably a porous material, for example, a porous material using PET or PA. In addition, the porosity, cross-sectional size, etc. of the liquid absorbent core having the property of allowing gas-liquid exchange can be appropriately set according to various conditions such as the amount of the liquid preparation 13 inside the bottle 11 and the viscosity of the liquid preparation 13. preferable. In the case of using a liquid absorbent core having the property of allowing gas-liquid exchange as the liquid absorbent core 19, it is preferable that the liquid absorbent core 19 usually has a porosity of 20% or more, more preferably a porosity of 20 to 80%. More preferably, the porosity is 30 to 80%. In addition, the core diameter of the liquid absorption core 19 is 2-15 mm, and 4-12 mm is especially preferable. Moreover, the length of the liquid absorption core 19 is 10-30 mm, and 10-20 mm is especially preferable.

The lower container 12 is assembled with a volatilizing body 22 at a position facing the liquid absorbent core 19, and a volatilizing body fixing / holding portion 14 is formed. Further, the lower container 12 may have a liquid storage chamber 23 below the volatilization body 22, and when the lower container 12 has the liquid storage chamber 23, the volatilization body 22 has a liquid absorption part 26. .
The volatilization body 22 is obtained by integrally molding the base 24, the four volatilization parts 25, and the liquid absorption part 26, that is, integrally molding with the same material. The volatilization body 22 is formed so that the lower end portion of the bottle 11 (that is, the liquid absorption core 19) and the upper surface of the base portion 24 are in surface contact, and further, the base portion 24 and the four volatilization portions 25 form a substantially vertical shape, that is, The bottom container (base 24) and the wall surface (four diffusion parts 25) connected to the bottom surface substantially vertically are fixed and held in the lower container 12 by the volatilizer fixing and holding part 14 in the lower container 12, The liquid preparation 13 is supplied from the bottle 11 through the core 19, and the liquid preparation 13 is volatilized from the four volatilization units 25. Here, “substantially vertical” means an angle that is recognized as substantially 90 ° within ± 10 ° from the vertical direction.
The four volatilization portions 25 extend from the four end edges of the base portion 24 formed in a square plate shape in a substantially vertical direction to the vicinity where they contact or contact the inside of the volatilization opening 15.
The volatilizer fixing / holding unit 14 is in one mode of fixing and holding the volatilizing body 22 in contact with the outer surface of the volatilizing unit 25, but the volatilizer fixing / holding unit 14 is formed at an angle formed by the two volatilizing units 25. An embodiment in which the volatilizer 22 is fixed and held by being incorporated is preferred, and FIG. 1 is a diagram showing the latter embodiment.
The liquid absorption part 26 is cut along the two edges of the base part 24 so as to have a predetermined width dimension, and is bent so as to protrude from the lower surface of the base part 24 toward the liquid storage chamber 23. Yes. The liquid absorption part 26 has a function of returning the liquid preparation 13 accommodated in the liquid storage chamber 23 to the volatilization body 22.

  As the volatilization body 22, any material can be used as long as it can hold the liquid preparation 13 and can volatilize the active ingredient of the liquid preparation 13, and specifically, resin, pulp, non-woven fabric, etc. A porous material made of an inorganic material such as an organic material, glass fiber, glass powder, or the like can be used. Particularly preferable materials for the volatilization body 22 include pulp, nonwoven fabric, and the like. Moreover, the volatilization body 22 may consist of a some material. For example, the volatilization body 22 is made of pulp as a main raw material and bonded with a binder, and has a structure in which tissue-like pulp materials, nonwoven fabrics, etc. are stretched on the front and back surfaces in order to improve surface strength and shape retention. It is preferable to do. Moreover, you may make it acquire the effect that the active ingredient of the hold | maintained liquid formulation 13 volatilizes by making the volatilization body 22 hold | maintain the liquid preparation 13 of predetermined amount previously at the time of opening of use simultaneously with opening. 2-12 mm is preferable and, as for the thickness of the volatilization body 22, 3-10 mm is especially preferable. Moreover, you may use for the volatilization body 22 what mixed and adhered the component which has a deodorizing function and antibacterial functions, such as green tea powder, activated carbon powder, and coffee bean powder. Further, the receptor (soluble or sparingly soluble) containing and holding the active ingredient or additive in the desired carrier is held in the volatilizer 22, and the receptor is gradually dissolved by the supplied liquid preparation 13. Also good. The volatilizer 22 may be polymer powder, polymer fiber, or the like having at least one of hydrophilicity and lipophilicity, which has a large liquid absorption capacity. In this case, the liquid reservoir 23 can be minimized or omitted as long as the present invention can be achieved.

Here, in the inverted volatilization device 10 before use, since the cap 21 that seals the liquid absorbent core 19 presses the volatilization body 22, the dent corresponding to the thickness of the cap 21 is the upper surface portion of the base 24 of the volatilization body 22. To occur. However, by removing the cap 21 during use, the depression of the upper surface portion of the base portion 24 caused by pressing is restored, and the liquid absorbent core 19 and the upper surface portion of the base portion 24 come into surface contact, so that the volatilizer 22 absorbs liquid. The liquid preparation 13 is supplied through the core 19.
Here, the volatilization body of the inverted volatilization device 50 described in Patent Documents 1 and 2 is arranged with sufficient space in the lower container, and each of the four volatilization parts 65 faces the volatilization opening 55. Spreads like a bud opening. That is, since the angle formed by the connecting portion between the base portion 64 and the volatilization portion 65 is an angle larger than 90 °, the volatility of the volatilization body is high, and the dent on the upper surface of the base portion 64 generated by the cap 61 before use is It is easy to restore.
On the other hand, the volatilization body 22 of the inverted volatilization apparatus 10 according to the present invention is disposed in the lower container 12 by the volatilization body fixing and holding part 14 in the lower container 12 such that the base 24 and the four volatilization parts 25 form a substantially vertical shape. Therefore, depending on the material of the volatilization body 22, the dent on the upper surface of the base 24 may be more difficult to restore than that of the inverted volatilization device described in Patent Documents 1 and 2 above.
Therefore, it is preferable that the density of the volatilizer 22 is in the range of 0.19 to 0.50 g / cm ³ . If the density of the volatilizer 22 is 0.19 g / cm ³ or more, the dent in the upper surface portion of the base portion 24 generated before use is restored during use, and the liquid absorbent core 19 and the upper surface portion of the base portion 24 are sufficiently flat. In contact, the volatilizer 22 can be supplied with the liquid preparation 13 via the liquid absorbent core 19. Further, when the density of the volatilization body 22 is 0.60 g / cm ³ or more, the bottle 11 and the lower container 12 do not fit together, and the bottle 11 and the lower container 12 are deformed and assembled when trying to fit together. Its density must be 0.50 g / cm ³ or less. The volatilization body 22 having a density of 0.19 to 0.50 g / cm ³ can sufficiently absorb the liquid preparation 13. Furthermore, the density of the volatilization body 22 is more preferably 0.19 to 0.30 g / cm ³ .

Although the inverted volatilization apparatus 10 which concerns on this invention may abbreviate | omit the liquid pool chamber 23, the case where it has is demonstrated below. The liquid storage chamber 23 has a bottom and is open at the top, and the volatilization body 22 is assembled to the open top. The liquid storage chamber 23 soaks the liquid preparation 13 from the bottle 11 into the volatilization body 22, and when the volatilization body 22 becomes saturated and exceeds its liquid holding capacity, It has a function to accommodate once. Therefore, it is preferable that the tip of the liquid absorption part 26 is disposed so as to contact the bottom plate 27 of the liquid storage chamber 23 in order to absorb all the liquid preparation 13 collected in the liquid storage chamber 23 without waste. .
On the other hand, the liquid storage chamber 23 may be replaced with a liquid absorption part 26 having substantially the same size as the volume. In this case, the liquid absorption part which returns the liquid formulation 13 to the volatilizer 22 can be omitted.

  As shown in FIG. 3, the volatilization body 22 has four volatilization portions 25 projecting substantially vertically upward from the four end edges of the base portion 24 in the shape of four rectangular plates. The volatilization body 22 can form the base 24, the four volatilization parts 25, and the liquid absorption part 26 only by making a notch in square plate-shaped material, for example. Therefore, since the liquid absorption part 26 can be produced simultaneously when manufacturing the volatilization body 22, productivity can be improved. Moreover, since the liquid absorption part 26 is integrally molded with the base 24, the liquid preparation 13 accommodated in the liquid storage chamber 23 can be efficiently returned to the volatilization body 22.

  In such an inverted volatilization apparatus 10, the liquid preparation 13 stored in the bottle 11 is impregnated in the liquid absorption core 19, and then impregnated in the volatilization body 22, whereby the liquid is quantitatively discharged from the bottle 11. . And the air containing the active ingredient of the liquid formulation 13 is spread | diffused outside from the four volatilization parts 25 of the volatilization body 22 through the opening part 15 for volatilization. When the gas in the head space in the upper part of the bottle 11 expands due to the temperature rise, the liquid preparation 13 in the bottle 11 may be excessively supplied to the volatilizer 22 through the liquid absorbent core 19. At that time, when the volatilizer 22 becomes saturated and exceeds its liquid holding capacity, the liquid preparation 13 in an amount corresponding to the excess is temporarily stored in the liquid storage chamber 23. And the liquid formulation 13 accommodated in the liquid reservoir 23 is returned to the volatilization body 22 by the liquid absorption part 26 by capillary action. Accordingly, the liquid preparation 13 accommodated in the liquid storage chamber 23 is returned to the volatilization body 22 and therefore does not remain in the liquid storage chamber 23. Therefore, according to the inverted volatilization apparatus 10, the liquid preparation 13 is prevented from leaking out, and the liquid preparation 13 can be used up without waste.

Of course, in order to prevent the liquid preparation 13 from leaking, it is conceivable to eliminate the volatilization opening 15 or make the volatilization opening 15 have an extremely small opening area. Since the opening area of 15 greatly affects the volatilization amount, for example, when the opening area of the volatilization opening 15 is reduced, the volatilization amount decreases, and when the liquid preparation is a fragrance, the fragrance strength and fragrance This is not preferable because the sustainability is deteriorated. Further, in order to prevent the liquid preparation 13 from leaking, it is conceivable to increase the volume of the portion of the lower container 12 to which the liquid preparation 13 is supplied, but in this case, the overall design of the inverted volatilization apparatus 10 is unbalanced. Therefore, not only is the appearance unfavorable in terms of design, but also the volume of the volatilization body needs to be increased as the volume increases, which is disadvantageous in terms of price. The volatilization opening 15 may be provided with means for adjusting the opening area. Further, specific opening area of volatilization opening 15, 10～60Cm ² selfishness, 15～50Cm ² is more preferable.

As described above, according to the inverted volatilization apparatus 10 which is an embodiment of the present invention, the volatilization body 22 is fixedly held in the lower container 12, so that the volatilization body is desirable in the lower container 12. It arrange | positions without shifting | deviating from a position, does not produce the undesirable situations, such as the volatilization body 22 protruding from the inverted volatilization apparatus 10, and does not stain the surrounding things, such as a user and a curtain. Further, the volatilization body 22 can be uniformly arranged at the correct position of the lower container 12 from any of the users set by the volatilization body fixing / holding portion 14 in the lower container 12.
Moreover, since the volatilization body 22 is located in the vicinity of the contact or contact with the inside of the volatilization opening 15, it exhibits excellent volatilization and diffusion effects, and can maintain a suitable volatilization efficiency for a long period of time. . Furthermore, since the volatilization body 22 has a sufficient volatilization area while the base 24 and the four volatilization parts 25 form a substantially vertical shape and a compact shape, sufficient volatilization and diffusion effects can be obtained even in a limited space. Can do.
Since the volatilization body 22 arranged at a correct position in the lower container 12 can receive a sufficient amount of the liquid preparation 13, the desired volatilization and diffusion effect can be obtained. In particular, by setting the density of the volatilizer 22 to 0.19 to 0.50 g / cm ³ , the dent in the upper surface portion of the base portion 24 generated before use is restored during use, and the upper surfaces of the liquid absorbent core 19 and the base portion 24 are restored. The volatilization body 22 is supplied with the liquid preparation 13 via the liquid absorbent core 19, and the volatilization body 22 can sufficiently absorb the liquid preparation 13.

Furthermore, the inverted volatilization apparatus 10 of this invention can change the shape of the bottle 11 or the lower container 12 into another designable shape according to the place to use, the purpose to use, etc. As an example, FIGS. 4 and 5 show another embodiment of the inverted volatilization apparatus 10.
The present invention is not limited to these embodiments, and modifications, improvements, and the like can be appropriately made such as combining the above-described embodiments. For example, a gas permeable container in which a gas adsorbent (for example, activated carbon, zeolite, etc.) is sealed may be fitted to the upper end of the liquid absorbent core 19. Then, the internal pressure in the bottle 11 can be adjusted. For this reason, it is possible to prevent liquid leakage from occurring when the inverted volatilization apparatus 10 is displayed and stored. Moreover, you may provide the pattern which improves an external appearance decoration property in the upper part of the bottle 11, or the whole. If it does so, the aesthetics according to the place and purpose to be used can be improved.
Moreover, you may cover the surface which is in surface contact with the liquid absorption core 19 of the volatilization body 22 with a liquid diffusion sheet. If it does so, the liquid formulation 13 will be spread | diffused uniformly to the volatilization body 22 with a liquid diffusion sheet, and since the liquid formulation 13 spreads over a wide area in a short time, a fragrance speed | velocity | rate can be improved.
If the volatilization part 25 of the volatilization body 22 is a shape which forms substantially perpendicular | vertical with the base 24, you may shape | mold in the shape etc. with the design property. Moreover, the liquid absorption part 26 may protrude and be formed from any of the base part 24 and the volatilization part 25, and may be provided with two or more as needed. Furthermore, volatilization efficiency can be improved by providing a plurality of volatilization holes in the volatilization part 25 of the volatilization body 22.

  Hereinafter, although the volatilization body in the inverted volatilization apparatus of this invention is demonstrated in more detail by a test example etc., this invention is not limited to these examples. In Examples, unless otherwise specified, parts means parts by weight.

(2) Test method 1 (restorability)
Tests were performed using a plurality of test volatilizers which were artificially provided with dents produced at the time of cap mounting using polyester or pulp volatilizers having different densities shown in Table 1 below. Moreover, the test sample 1 or 2 was used as a test sample, respectively.
The bottle filled with the test specimen and the test volatilizer were fixed and held at a predetermined position in the lower container, and the bottle and the lower container were fitted. After 24 hours, it was confirmed whether the test volatilizer absorbs the test specimen. (When the dent of the test volatilizer is restored and the liquid absorbent core and the test volatilizer are sufficiently in surface contact, the test volatilizer is fed from the bottle to the test volatilizer.)
The test results are shown in Table 1 as “◯” when all of the test volatilizers subjected to the test absorb liquid, and “x” when there is one test volatilizer that does not absorb any liquid. There was no difference in the results of the restorability test depending on the type of test sample 1 or 2.
(3) Test method 2 (liquid absorbency)
As the test volatilization body, the size was “56 mm × 60 mm × 4 mm” and “56 mm × 60 mm × 8 mm”, and the density was tested using a plurality of polyesters or pulps shown in Table 1 below. . Moreover, the test sample 1 or 2 was used as a test sample, respectively.
The surface consisting of “56 mm × thickness (4 mm, 8 mm)” of the test volatilizer is used as the bottom, 10 mm from the bottom is immersed in the test specimen, and the top surface of the test volatilizer absorbs the test specimen after 24 hours. It was confirmed.
The test results are shown in Table 1 as “◯” when all of the test volatilizers subjected to the test absorb liquid, and “x” when there is one test volatilizer that does not absorb any liquid. In addition, the volatilization thing of the same density showed the same liquid absorptivity irrespective of the thickness, and there was no difference in the result of the liquid absorptivity test by the kind of the test sample 1 or 2.
