Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical liquid volatilization device in which various volatile chemical liquids such as fragrances and deodorants are contained and a core material for sucking the chemical liquid is immersed in the chemical liquid.

[0002]

2. Description of the Related Art Heretofore, as a chemical liquid volatilization device of this kind, for example, a utility model registration No. 3020459 by the applicant of the present application.
Some of them are disclosed in Japanese Patent Application No. 2001-338591.

In any of these chemicals volatilization devices, a volatilization section above a core material is drawn out from an upper opening of a chemical solution container accommodating a chemical solution, and the core material volatilization section is brought into contact with the inner peripheral portion of the opening for support. In this state, the liquid absorbing part connected to the volatilizing part sucks up the chemical liquid and volatilizes it.

[0004]

[Problems to be Solved by the Invention]
There are the following problems depending on the internal shape of the chemical liquid container, the size of the core material, and the arrangement state.

As shown in FIG. 7, the conventional chemical solution volatilization apparatus is used when the core material 6 is not pulled out from the chemical solution container 3.
The liquid absorbing part 5 of the core material 6 is in a bent state as shown in the drawing.

Then, depending on the bent state,
When the volatilization part 4 of the core material 6 is pulled up from the opening 2,
As shown in, the liquid absorbing part 5 of the core material 6 is pulled up in a bent state and is pressed against the inner wall of the liquid medicine container 3 in that state, so that the liquid absorbing part 5 comes out of the liquid medicine 3 and sucks up the liquid chemical. There was a problem that I could not do it. Further, when the filter paper was dried, it took a long time to volatilize the drug again, and during that time, a stable amount of the drug solution could not be volatilized.

Therefore, according to the present invention, regardless of the shape of the container, the size of the core material, or the bent state of the liquid absorbing portion when the core material is not pulled out, the liquid absorbing portion can be formed when the core material is pulled up. An object of the present invention is to provide a chemical solution volatilization device and a core material thereof that can obtain stable chemical vaporization without being pulled out in a bent state and coming out of the chemical solution.

[0008]

In order to achieve the above object, a chemical solution volatilization apparatus according to the present invention comprises a chemical solution container having an opening at an upper portion, and an inner peripheral portion of the opening when pulled up from the opening. A volatilization part that is supported in contact with and can maintain a protruding posture from the opening part, and is flexible and can be continuously provided to the volatilization part and suck up the drug solution in the drug container and supply it to the volatilization part. A core material having a liquid absorbing portion, and the liquid absorbing portion is provided with a weakened portion having increased flexibility.

Further, the core material of the chemical liquid volatilization apparatus according to the present invention is supported through the inner peripheral portion of the opening portion of the chemical liquid container when being pulled up from the opening portion of the chemical liquid container, and can maintain the projecting posture from the opening portion. A core material comprising a volatilization part and a liquid absorption part which is flexible and continuously provided to the volatilization part and which can suck up the chemical liquid in the drug container and supply it to the volatilization part, wherein the liquid absorption part In addition, it is characterized by having a weakened portion with increased flexibility.

The weak portion is preferably at least one notch formed in the liquid absorbing portion.

The notch can be formed by extending in the width direction of the liquid absorbing portion or extending in the length direction of the liquid absorbing portion.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to the drawings. Throughout the drawings, the same components are denoted by the same reference numerals.

FIG. 1 is a perspective view showing the chemical liquid volatilization device in a state where the core material is pulled out to the maximum pull-up position, and FIG. 2 is a perspective view of the chemical liquid volatilization device in a state where the core material is pushed in to the maximum pull-down position.

The chemical liquid volatilization apparatus 1 is supported via the chemical liquid container 3 having an opening 2 at the upper part and the inner peripheral portion of the opening 2 when pulled up from the opening 2, and maintains a protruding posture from the opening 2. And a core material 6 having a flexible volatilizing part 4 and a liquid absorbing part 5 which is flexible and continuously provided to the volatilizing part 4 and capable of sucking up and supplying the drug solution in the drug container 3 to the volatilizing part 4. The point is the same as the conventional one, and is different from the conventional one in that the liquid absorbing portion 5 is provided with a weak portion for enhancing flexibility.

In the illustrated example, the core material 6 is wound around the support frame 8 attached to the cap 7, and the support frame 8 and the core material 6 are brought into frictional contact with the inner peripheral portion of the opening 2 to thereby form the core material 6. However, it is also possible to support the inner peripheral portion of the opening 2 only by the core material 6 without providing a supporting frame.

The core material 6 comprises a volatilization part 4 and a liquid absorption part 5,
The volatilization part 4 that can maintain the protruding posture from the opening is the opening 2.
The liquid absorbing part 5 is formed to have a width substantially the same as the inner diameter of the core, and is provided continuously to the volatilizing part 4 so as to suck up the chemical liquid and supply it to the volatilizing part 4. When the core material 6 is pushed to the maximum pull-down position, It is narrowed to give flexibility on the assumption that it will bend. Further, the core material 6 has such a length that the lower end thereof reaches the bottom of the chemical liquid container 3 when pulled out to the maximum pull-up position.

The core material 6 is not particularly limited in material and the like as long as it can absorb and volatilize the chemical liquid and volatilize, and the liquid absorption part 5 has flexibility. For example, natural fibers such as paper and pulp. Examples thereof include a nonwoven fabric or knitted fabric made of artificial fibers or mixed fibers thereof, a sponge material made of synthetic resin such as urethane foam, or a molded product of a plastic film or the like.

The weak portion can be formed by a notch 10 extending in the width direction of the liquid absorbing portion 5 as shown in FIGS. 1 and 2, or in the length direction of the liquid absorbing portion 5 as shown in FIG. It can be formed by the notch 11 extending to the other side, and can be formed by punching, compression, a thin portion, or by partially reducing the basis weight, although not shown.

When the notch 10 is formed in the width direction of the liquid absorbing portion 5, the notch 10 is preferably formed in the liquid absorbing portion 5 particularly in a portion X shaded in FIG. That is, it is preferable that the core material 6 is formed so as to be easily bent from the bent state when the core material 6 is pushed to the maximum pull-down position and to be easily recovered from the bent state when the core material 6 is pulled up.

If the weak portion is formed in the core material 6 in this way, the flexibility is enhanced, and when the core material 6 is pulled out, the core material 6 may be pulled up in a bent state and the core material 6 may come out of the chemical solution. There is no.

By forming the weak portion by the cut as described above, the non-volatile component is deposited in the cut portion, and the amount reaching the volatilization portion 4 is reduced. as a result,
In the past, since the non-volatile component was deposited on the volatilization part 4 to reduce its volatilization performance, the chemical solution could not be refilled. However, in the core material 6 with the notch formed in the liquid absorption part 5, the volatilization part 4 It also has the effect of suppressing the deposition of non-volatile components in the solution and enabling the refilling of the chemical solution.

[0026]

[Table 1]

As is clear from Table 1, it is understood that the defect occurrence rate decreases as the number of cuts increases.

[0028]

[Table 2]

In the case of Table 2 as well, it can be seen that, like Table 1, the defect occurrence rate decreases as the number of cuts increases.

[0030]

[Table 3] Table 3 shows the results of testing the defect occurrence rate by changing the cutting depth of the core material 6 only for the implemented product. The basis weight of the core material was 600 g / m ² , and the number of cuts was 9.

As can be seen from Table 3, the defect occurrence rate decreases as the cutting depth becomes deeper, and particularly when the cutting depth is 4 mm or more, the defect occurrence rate significantly decreases.

[0032]

[Table 4] Next, Table 4 shows the test results comparing the volatilization rates of the chemicals. In Table 4, the vertical axis is the ratio of the remaining amount of the chemical liquid, and the horizontal axis is the number of days. The measurement conditions were that the temperature was 25 ° C. and the humidity was 35%, and the sample was allowed to stand in a windless space. 400 ml of chemical solution for implemented product and conventional product
Each of the five was volatilized in the above, and the average value was plotted for the remaining ratio. As the practical products, those having notches formed on both sides were used as in Table 1, but the number of notches was 11 was used. The cutting depth was 5 mm.

As can be seen from Table 4, there is almost no difference in the volatilization rate between the embodied product and the conventional product, and it can be seen that the volatilization speed does not slow down due to the formation of the notch in the core material.
