Description

  The present invention relates to a chemical vaporization container.

  Conventionally, various containers for storing chemicals such as fragrances have been proposed. For example, Patent Document 1 discloses a chemical solution volatilization container in which a chemical solution is stored in a liquid-tight and gas-impermeable bag-shaped inner container, and further this inner container is stored in a bag-shaped outer container. . An opening covered with a gas permeable film is formed in a part of the outer container. And this container is used as follows. First, by applying an external force to the outer container, the internal pressure of the inner container accommodated therein is increased and a part thereof is broken. Thus, the chemical liquid flows out from the broken portion to the outer container. The chemical solution that flows out volatilizes out of the gas permeable film. As a result, an aroma effect can be obtained.

Japanese Utility Model Publication No. 60-1730

  However, since the gas permeable film is provided only in a part of the outer container, the above-described container cannot volatilize a sufficient amount of the chemical solution to the outside. Therefore, it is conceivable to enlarge the opening of the outer container. However, since the inner container is disposed at the end of the outer container, it is difficult to volatilize the chemical solution throughout the outer container. In addition, the strength of the scent by the chemical solution depends on the concentration of the fragrance vaporized in the outer container. In the above container, the chemical solution storage area and the gas permeable film are separated from each other. There is also a problem that the fragrance is weakened.

  The present invention has been made in order to solve the above-described problem, and a chemical liquid volatilization container capable of effectively volatilizing a chemical liquid in a wider range and capable of maintaining the volatilization amount of the chemical liquid in the later stage of use. The purpose is to provide.

  The chemical volatilization container according to the present invention has an opening, an outer container in which the chemical liquid is accommodated, a gas permeable sheet that covers the opening, and an inner side of the outer container along the gas permeable sheet. And a diffusion member for diffusing the chemical liquid in the surface direction.

  According to this configuration, since the diffusion member is provided along the gas permeable sheet, the chemical solution in the outer container can be diffused along the gas permeable sheet. Therefore, a chemical | medical solution can be volatilized over the wide range of a gas-permeable sheet, and the volatilization component of a chemical | medical solution can be discharge | released with respect to the exterior in a wide area. Moreover, since a chemical | medical solution diffuses along a gas-permeable sheet, the chemical | medical solution component can be volatilized outside in a large area also in the late stage of use where the chemical | medical solution decreased, and the effect that fragrance intensity | strength cannot fall easily can also be acquired. The diffusing member may be brought into contact with the gas permeable sheet, or may be disposed in the vicinity without being brought into contact with the gas permeable sheet. Even when the diffusing member is arranged in the vicinity of the gas permeable sheet, the volatilization concentration of the chemical liquid in the vicinity of the gas permeable sheet is high, so that the chemical liquid can be volatilized outside at a higher concentration than the conventional example. .

  Although the said diffusing member can be made into various forms, for example, it can be formed in a sheet shape to cover the opening. Thereby, since the diffusion member is provided over the entire surface of the gas permeable sheet, the volatile component of the chemical liquid can be released over the entire surface of the volatile region.

  The diffusion member can be fixed to the periphery of the opening together with the gas permeable sheet. Thereby, since the gas permeable sheet and the diffusing member are in contact with each other at least at the peripheral portion of the opening, for example, a gap is formed between the gas permeable sheet and the diffusing member. The gas permeable sheet can be brought into contact with the chemical solution via the diffusion member from any position on the periphery of the opening. Therefore, since a certain contact area or more between the diffusing member and the gas permeable sheet is ensured in the peripheral portion, it is possible to prevent the volatilization amount of the chemical solution from being greatly reduced as a whole.

  Various methods can be used for storing the chemical solution in the outer container. For example, it is possible to further provide an inner container in which the chemical solution is sealed and can be opened by an external force, and the inner container is stored in the outer container. it can. At this time, it is desirable that the outer container is configured to be flexible. In such a configuration, when an external force is applied to the outer container to exert a force on the inner container, the inner pressure of the inner container increases and the inner container breaks. Thereby, the chemical | medical solution of an inner container flows out to an outer container, and the volatilization component of a chemical | medical solution is discharge | released from an outer container. According to this configuration, if an inner container in which a chemical solution is sealed is prepared in advance, the chemical solution can be stored in the outer container simply by storing the inner container in the outer container. . In addition, when the chemical solution is directly stored in the outer container, the chemical solution may wet the outer container, the diffusion member, and the gas permeable sheet, and may hinder the connection between the outer container, the diffusion member, and the gas permeable sheet during the manufacturing process. However, this can be prevented if the chemical solution is sealed in the inner container as described above.

  The gas permeable sheet can also be configured to diffuse the chemical in the surface direction. If it does in this way, even if the contact part of a gas-permeable sheet and a diffusion member is small, since the spreading | diffusion of the chemical | medical solution by a gas-permeable sheet is possible, a chemical | medical solution can be volatilized in a wide range.

  The diffusion member can be formed of various materials, but can be formed of, for example, a nonwoven fabric. Other than non-woven fabrics, for example, porous sintered bodies such as paper, wood, and ceramics, plastics, and metals can be processed into sheets, nets, or rods if chemicals can be diffused in the surface direction. Various members such as those made can be used. Moreover, a groove | channel, embossing, etc. can be formed in these members, and it can also comprise so that the spreading | diffusion to the surface direction of a chemical | medical solution can be performed easily.

  According to the chemical liquid volatilization container according to the present invention, the chemical liquid can be effectively volatilized to the outside even if the opening for volatilizing the chemical liquid is enlarged. Further, the volatilization amount of the chemical solution can be maintained even in the later stage of use.

  Hereinafter, an embodiment of a chemical vaporization container according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of this chemical vaporization container, and FIG. 2 is a plan view (a) and a side view (b) of FIG. In the following, for convenience of explanation, the left and right of FIG. 2A are the width direction, the top and bottom of FIG. 2A are the vertical direction, the left of FIG. 2B is the rear side (or the back side), and the right is the front side. With reference to this, the description will be made in other drawings.

  As shown in FIGS. 1 and 2, the chemical vaporization container 1 according to this embodiment includes an outer container 11 and a rectangular inner container 12 accommodated in the outer container 11. In addition, in FIG. 1, although the chemical | medical solution volatilization container 1 is arrange | positioned vertically, the direction of arrangement | positioning will not be specifically limited if the gas-permeable sheet | seat 113 mentioned later is not block | closed. The inner container 12 is formed in a bag shape with a transparent film, and is formed of a known resin material that does not transmit gas and liquid. And in the inner container 12, the colored chemical | medical solution which has an aromatic component is enclosed. As this chemical solution, a known volatile fragrance or the like can be used. An opening 121 that is heat-sealed by heat sealing is formed at one end of the inner container 12, and is configured to break by applying an external force to increase the internal pressure of the inner container 12. .

  The outer container 11 includes a container body 111 formed of a resin material having a convex portion on the front side and having a transparent flexibility. Moreover, the back side of this convex part is covered with the nonwoven fabric 112 and the gas-permeable sheet 113, and the accommodating part 115 is formed in the inside, The inner container 12 mentioned above is arrange | positioned at this accommodating part 115. FIG. A flange portion 118 is formed around the convex portion of the outer container 11, and the outer shape of the flange portion 118 is formed in a rectangular shape in front view as a whole. And the nonwoven fabric 112 and the gas-permeable sheet 113 are arrange | positioned in this order on the back surface of this flange part 118, and the back surface of a convex part is covered (refer the enlarged view of FIG.2 (b)). . That is, the nonwoven fabric 112 and the gas permeable sheet 113 are formed to have substantially the same size as the outer shape of the outer container 11 and are fixed by being thermally fused to the flange portion 118.

  The gas permeable sheet 113 described above can be formed of various materials, but can transmit a volatile fragrance, and a permeation rate at which the fragrance permeates the sheet is volatilized by the fragrance permeated through the sheet. The sheet can be made of a material having a speed or less. For such a sheet, for example, a volatilization component sustained release film described in JP-A-2007-169467, a film described in JP-T-2008-545591, and the like can be employed, which are known in the art. It is. In addition, the gas permeable sheet 113 itself can also have a diffusion performance. In this case, for example, a high-density polyolefin / fine silica film described in JP-T-2008-545591 can be employed. The gas permeable sheet 113 may be a single layer sheet made of one kind of material, or may be a sheet in which two or more layers made of the same or different materials are laminated.

  On the other hand, the nonwoven fabric 112 is not particularly limited as long as it is a material capable of diffusing a chemical in the surface direction by capillary action as a diffusion member. In addition, the location blocked by the nonwoven fabric 112 and the gas permeable sheet 113 on the back side of the convex portion constitutes the opening of the outer container 11 in the present invention.

  Then, the usage method of the chemical | medical solution volatilization container comprised as mentioned above is demonstrated, also referring FIG. First, the accommodating part 115 of the outer container 11 is pressed with a finger or the like. Thereby, the inner container 12 inside the accommodating part 115 is also pressed simultaneously, and the internal pressure of the inner container 12 rises. As a result, the opening 121 of the inner container 12 is broken. In this way, as shown in FIG. 3, the chemical solution in the inner container 12 flows out from the opening 121 to the accommodating portion 115. Then, the chemical | medical solution of the accommodating part 115 volatilizes outside from the gas-permeable sheet 113 through the nonwoven fabric 112, and there exists an aroma effect. Furthermore, the chemical | medical solution of the accommodating part 115 is spread | diffused in the surface direction according to the capillary phenomenon along the nonwoven fabric 112. FIG. Since the nonwoven fabric 112 is in contact with the gas permeable sheet 113, the fragrance component of the chemical liquid volatilizes from the gas permeable sheet 113 to the outside as the chemical liquid diffuses in the nonwoven fabric 112. As a result, the aromatic component of the chemical liquid is volatilized from the entire surface of the gas permeable sheet 113.

  As described above, according to the present embodiment, since the nonwoven fabric 112 is provided along the gas permeable sheet 113, the chemical liquid flowing out from the inner container 12 can be diffused along the gas permeable sheet 113. . Therefore, the chemical solution can be volatilized over a wide range of the gas permeable sheet 113, and the volatilization component of the chemical solution can be released to the outside over a wide area. Moreover, since a chemical | medical solution diffuses along the gas-permeable sheet 113, a chemical | medical solution component can be volatilized outside in a large area and the fragrance intensity | strength can be maintained also in the late stage of use where the chemical | medical solution decreased.

  As described above, since the non-woven fabric 112 has high diffusion performance, the chemical solution diffuses throughout the non-woven fabric 112 even if a portion thereof is impregnated with the chemical solution. And the nonwoven fabric 112 and the gas-permeable sheet 113 contact in the area | region where the chemical | medical solution spread | diffused, and are volatilized outside. On the other hand, when a gap is formed between the nonwoven fabric 112 and the gas permeable sheet 113 for some reason, the volatilized chemical component is directed from the nonwoven fabric 112 to the gas permeable sheet 113 through the gap and released to the outside. However, compared with the case where the nonwoven fabric 112 and the gas-permeable sheet 113 are contacting, the volatilization amount of a chemical | medical solution decreases. On the other hand, in this embodiment, since the gas-permeable sheet 113 and the nonwoven fabric 112 are fused together at the flange portion 118, they are in contact with each other at least at the periphery of the accommodating portion 115. Therefore, for example, as shown in FIG. 4 (b), even if a gap is formed between the gas permeable sheet 113 and the nonwoven fabric 112 and the contact portion becomes smaller, the gas permeable sheet 113 is formed at the periphery of the opening. The chemical solution can be contacted via the nonwoven fabric 112 from any position. In the example of FIG. 4, the chemical | medical solution stored under the outer container 11 has contacted the gas-permeable sheet 113 through the nonwoven fabric 112, and has shown a mode that the aromatic component has volatilized outside from here. In addition, in Fig.4 (a), the area | region where the chemical | medical solution volatilizes in contact with the nonwoven fabric 112 in the gas-permeable sheet 113 is shown by the shading. And since the clearance gap is formed between the gas-permeable sheet 113 and the nonwoven fabric 112 in the intermediate part of the accommodating part 115, the nonwoven fabric 112 and the gas-permeable sheet 113 do not contact in this part. However, since the chemical solution is diffused over the entire surface of the nonwoven fabric 112, and the nonwoven fabric 112 and the gas permeable sheet 113 are in contact with each other at the periphery of the accommodating portion 115, the gas permeable sheet 113 is formed at the periphery. It can be volatilized in contact with the chemical solution via the nonwoven fabric 112. Therefore, even if a gap is formed between the gas permeable sheet 113 and the nonwoven fabric 112, a contact area of a certain level or more is secured at the peripheral edge portion, thereby preventing a significant reduction in the volatilization amount of the chemical liquid as a whole. can do.

  Further, when the gas permeable sheet 113 is formed of, for example, a high-density polyolefin / fine powder silica film as described above and has a diffusion performance, the following effects can be obtained. This point will be described with reference to FIG. For example, as shown in FIG. 5, when a gap is formed between the gas permeable sheet 113 and the nonwoven fabric 112, the gas permeable sheet 113 passes through the nonwoven fabric 112 in the region where the gap is formed. However, since the chemical liquid diffuses on the gas permeable sheet 113 and volatilizes to the outside, it is possible to prevent the volatilization amount of the chemical liquid from decreasing (see FIG. 5B). In FIG. 5A, the chemical solution diffused on the gas permeable sheet 113 is shown by shading.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this, A various change is possible unless it deviates from the meaning. For example, as long as the said chemical | medical solution volatilization container 1 is arrange | positioned so that the gas-permeable sheet | seat 113 may not be obstruct | occluded as mentioned above, the direction is not limited. Moreover, you may arrange | position directly in a desired place at the time of use, and can also be accommodated and used for another container. Or it can arrange | position to the following support stands. Hereinafter, an example of the support base will be described. FIG. 6 is a front view (a), side view (b), and (c) rear view of the support base.

  As shown in FIG. 6, the support base 2 is formed in a trapezoidal shape when viewed from the front, and an accommodation space for accommodating the chemical vaporization container 1 is formed therein. An opening 21 is formed in the upper part of the support base 2, and the chemical liquid volatilization container 1 can be inserted into the accommodation space from the opening 21. A circular through-hole 22 is formed on the back surface of the support base 2 at a position facing the inner container 12 in the container 115 of the stored chemical vaporization container 1, and communicates with the storage space. A circular pressing member 23 is disposed in the through hole 22 and is suspended from the through hole 22 by a support member 24. Thus, when the pressing member 23 is pushed in from the back side of the support base 2, the pressing member 23 swings around the support member 24 and presses the accommodating portion 115 of the chemical volatilization container 1 in the accommodating space. ing. On the other hand, a cup-shaped receiving portion 25 that opens to the back side is disposed at a position facing the pressing member 23 in the housing space. The receiving portion 25 has a larger diameter than the pressing member 23 and receives the pressing member 23 that has been pushed into the accommodation space. The chemical vaporization container 1 inserted from the opening 21 is sandwiched between the pressing member 23 and the receiving portion 25. In addition, a plurality of slits 26 constituting a pattern are formed in the lower part of the back surface of the support base 2, and the chemical liquid volatilized from the chemical liquid volatilization container 1 is discharged to the outside through the slits 26. In the chemical liquid volatilization container 1, the position can be fixed by a known means in the housing portion 115 so that the inner container 12 in the housing portion 115 is disposed at a position facing the pressing member 23. . Although not shown in the drawings, a window portion communicating with the accommodation space at the position corresponding to the lower portion of the accommodation portion 115 is provided on the support base 2 so that the chemical liquid flowing out from the inner vessel 12 to the outer vessel 11 can be visually recognized. Can be provided.

  Then, the usage method of the support stand comprised as mentioned above is demonstrated, also referring FIG. First, as shown in FIG. 7, the chemical liquid volatilization container 1 is inserted from the opening 21 at the top of the support base 2, and the chemical liquid volatilization container 1 is arranged in the support base 2. When the pressing member 23 is pushed into the accommodation space in this state, the accommodation portion 115 is sandwiched between the pressing member 23 and the receiving portion 25. At this time, since the pressing member 23 has a smaller diameter than the receiving portion 25, the pressed pressing member 23 is pressed so as to enter the receiving portion 25. Thereby, the accommodating part 115 is pushed in so that the force which acts on the pressing member 23 may concentrate in the receiving part 25, and the inner container 12 inside the accommodating part 115 is also pressed simultaneously. Thus, the internal pressure of the inner container 12 increases and the opening 121 is broken. As a result, the chemical liquid that has flowed out to the accommodating portion 115 is volatilized to the outside from the gas permeable sheet 113 through the nonwoven fabric 112, and is released to the outside from the slit 26 of the support base 2 to exert an aroma effect.

  In the above embodiment, the gas permeable sheet 113 is brought into contact with the nonwoven fabric 112. However, these do not necessarily have to be brought into contact with each other, and even when they are brought close to each other, a high volatilization effect is obtained as compared with the conventional example without the nonwoven fabric 112. be able to. That is, when there is no non-woven fabric, the chemical solution is volatilized over the entire internal space of the outer container, so the concentration of the chemical solution is low, and as a result, the concentration of the chemical solution released from the gas permeable sheet is Lower. And this tendency becomes remarkable in the latter period of use of a chemical | medical solution. On the other hand, when the non-woven fabric 112 is disposed in the vicinity of the gas permeable sheet 113, the volatilization concentration of the chemical liquid in the vicinity of the gas permeable sheet 113 is increased, and the chemical liquid can be volatilized to the outside at a higher concentration than in the conventional example.

  In the above embodiment, the nonwoven fabric 112 is overlapped on the gas permeable sheet 113 to diffuse the chemical solution. However, as the diffusing member, other than the nonwoven fabric as long as the chemical solution can be diffused in the surface direction. For example, various members such as a porous sintered body such as paper, wood and earthenware, plastic, metal and the like processed into a sheet shape, a net shape, or a rod shape can be used. Moreover, a groove | channel, embossing, etc. can be formed in these members, and it can also comprise so that the spreading | diffusion to the surface direction of a chemical | medical solution can be performed easily.

  Moreover, in the said embodiment, although the chemical | medical solution is accommodated in the outer container 11 via the inner container 12, a chemical | medical solution can also be accommodated in the outer container 11 directly. In this case, in order to prevent liquid leakage, a liquid-impermeable sheet such as aluminum is pasted on the surface of the gas-permeable sheet 113 opposite to the diffusion member (nonwoven fabric, etc.). The permeable sheet can be peeled off. Even if it does in this way, since the diffusion member is provided, the effect similar to the said embodiment can be acquired.

  Examples of the present invention will be described below. However, the present invention is not limited to the following examples.

Here, the chemical liquid volatilization container which covers the back side of the convex part with the nonwoven fabric and the gas permeable sheet as shown in FIG. 1 to FIG. A chemical vaporization container covering the side was used as a comparative example. Each material is as follows.
(1) Outer container
It was formed by PE / PPT, the volume of the accommodating part was about 20000 mm ³ , and the outer dimension was 60 × 100 mm. The opening area of the accommodating portion covered with the nonwoven fabric and the gas permeable sheet was about 4500 mm ² .
(2) Inner container
It was formed by PET / EVOH, and a bag with an outer size of 40 × 50 mm was formed.
(3) Chemical liquid It was prepared with a fragrance (herb fragrance) / solvent (glycol ether) / colorant, and the filling amount into the inner container was 3.0 mL.
(4) Nonwoven fabric A nylon spunbonded nonwoven fabric (N05040 manufactured by Asahi Kasei) was used, and the outer dimensions were set to 60 × 100 mm, which was the same as that of the outer container.
(5) Gas permeable sheet The gas permeable sheet was formed of PE (Dalamic V5) blended with silica, and the outer dimensions were the same as the outer container, 60 × 100 mm.

Using the examples and comparative examples, the following two tests were performed after the inner container was accommodated in the accommodating portion.
(1) Appearance evaluation After opening the inner container, we observed how the colored chemical solution volatilizes from the gas permeable sheet. After opening the inner container, photographs were taken 0.5 hours and 24 hours later. . The results are as shown in FIG. According to the figure, it can be seen that the chemical solution has already spread and volatilized over the entire gas-permeable sheet after 0.5 hours due to the diffusion effect of the nonwoven fabric. On the other hand, in the comparative example, the chemical solution spreads only in the vicinity of the region where the chemical solution is stored in the lower part of the container after 0.5 hour, and does not spread over the entire gas permeable sheet even after 24 hours.

(2) Sensory evaluation The above examples and comparative examples were installed in a 4.7 tatami room, and the fragrance strength after 0.5 hours was evaluated by 11 scent workers. In the evaluation method, an evaluation value indicating that the fragrance becomes stronger as the numerical value increases at intervals of 0.5 from 0.0 to 7.0 was calculated, and the average was calculated. As a result, the example was 4.6 while the comparative example was 4.1. Furthermore, it was found that there were nine subjects who made the difference between the example and the comparative example 0.5 or more, and that there was a significant difference. Therefore, as derived from the results of the appearance evaluation, it was found that the scent becomes stronger when the chemical solution is volatilized in a wide range of the gas permeable sheet.
