JP 2011-004867 A

  In this type of chemical volatilizer, since the volatilizer sucks up the liquid chemical, the volatilized body is installed in a living room or an entrance, etc. while being wetted by the liquid chemical. Therefore, when a hand, clothes, a curtain, etc. touch the part of the upper end side exposed from the container of the volatilization body, there exists a subject that a liquid chemical | medical agent will adhere easily to a hand etc. and will be contaminated with a liquid chemical | medical agent.

  This invention is made | formed in order to solve the said subject, and it aims at providing the volatilization body and chemical | medical agent volatilizer which a liquid chemical | medical agent does not adhere to a hand etc. easily.

  The volatilization body of the present invention has a longitudinal shape, is a volatilization body that is used by being inserted into a container having an opening at the top and containing a liquid medicine inside, and extends in the longitudinal direction on the outer periphery. It is characterized by comprising at least one groove formed in the above, and made of a material having a contact angle of the liquid medicine of 90 ° or less.

  In the volatilization body of this invention, it is preferable to consist of a transparent material, and it is more preferable to consist of a colorless and transparent material.

  Moreover, in the volatilization body of this invention, it is preferable that they are glass or resin.

  The chemical volatilizer of the present invention is characterized by comprising the volatilized body having the above-described configuration, and a container having an opening in the upper part and containing a liquid chemical inside.

  According to the present invention, the volatilized body is formed of a material having a high affinity with the liquid drug having a contact angle of 90 ° or less for the liquid drug, so that the volatilized body is inserted into the container containing the liquid drug. In this case, when the volatilizer sucks up the liquid medicine in the groove by capillary action, the liquid level of the liquid medicine becomes lower than the depth of the groove, and the liquid level of the liquid medicine moves to the outer space side from the outer edge of the groove. It does n’t rise. Therefore, even if your hands, clothes, curtains, etc. touch the upper end exposed from the container of the volatilizer, the liquid chemical in the groove is difficult to adhere to your hands, etc. be able to.

It is explanatory drawing explaining the contact angle of a droplet.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a schematic configuration of a drug volatilizer 1 according to an embodiment of the present invention. The chemical volatilizer 1 includes a container 3 in which a liquid chemical 2 is accommodated and a plurality of volatilizers 4 inserted into the container 2. The plurality of volatilizers 4 are partially immersed in the liquid medicine 2 in the container 3 while a part on the upper end side is exposed on the container 2. The drug volatilizer 1 sucks up the liquid drug 2 in the container 3 by a plurality of volatilizers 4 and volatilizes it outside the container 3 so that the medicinal effect of the liquid drug 2 on the surrounding space where the drug volatilizer 1 is installed. Demonstrate.

  The liquid medicine 2 has volatility (medicine sustained release) and exhibits medicinal effects by gradually volatilizing the drug in the air. Examples of the liquid drug 2 include fragrances, deodorants, insect repellents and the like, but are not particularly limited, and depending on the purpose of use, perfumes, deodorant components, insect repellent components, coloring Fees and the like can be included alone or in combination. The solvent contained in the liquid medicine 2 is appropriately selected according to the type of additive used, and can be a hydrophilic solvent or a lipophilic solvent, or a mixture thereof. When the liquid medicine 2 contains a fragrance, it is preferable to contain at least a lipophilic solvent as a solvent in order to increase the scent strength. As the hydrophilic solvent, for example, water, ethanol, or a mixture thereof can be used. As the lipophilic solvent, for example, glycol ether or isoparaffinic solvent, or a mixture thereof can be used. In addition, in order to solubilize a fragrance | flavor, a deodorizing component, an insect repellent component, a coloring agent, etc., the liquid chemical | medical agent may contain the solubilizer.

  The container 3 is a bottomed container having an opening 30 in the upper portion and a space for storing the liquid medicine 2 therein. In the present embodiment, the container 3 includes a neck portion 31 having an opening 30, a shoulder portion 32 that continues to the neck portion 31, a hollow body portion 33 that continues to the shoulder portion 32, and a bottom portion 34 that continues to the lower portion of the body portion 33. It consists of and. The bottom portion 34 has a central portion that protrudes in a dome shape above the outer peripheral portion, and has a height that decreases from the central portion toward the outer peripheral portion. As a result, when the amount of the liquid medicine 2 in the container 3 becomes small with use, the liquid medicine 2 is stored in the outer peripheral portion of the bottom 34 having a low height, so that the remaining liquid medicine 2 is surely volatilized. The body 4 can suck up.

  In addition, the shape of the container 3 is not particularly limited, and containers having various shapes can be used as long as the container has an opening 30 in the upper portion and can accommodate the liquid medicine 2 therein. For example, the outer peripheral surface of the trunk portion 33 may be an uneven surface in which the unevenness is alternately repeated over the entire periphery.

  The container 3 may be any of transparent, translucent and opaque, and may be either colorless or colored. The term “translucent” means that the transparency is not completely transparent but has transparency that allows the inside to be visually recognized. When the container 3 is transparent or translucent, since the inside of the container 3 can be visually recognized from the outside, for example, the remaining amount of the liquid medicine 2 in the container 3 can be confirmed. The material of the container 3 is not particularly limited, and can be made of, for example, glass, plastic, or earthenware, and a material is appropriately selected in consideration of aesthetics.

  The volatilization body 4 has a longitudinal shape, and in the present embodiment, has a rod shape. The longitudinal shape refers to a shape whose length in one direction is sufficiently longer than the length in a direction orthogonal to the one direction. The volatilization body 4 does not necessarily have a rod shape, and may have, for example, an elongated plate shape.

  The length (size in the longitudinal direction) of the volatilization body 4 is such that the upper end protrudes from the upper opening 30 of the container 2 and the lower end reaches the inner bottom surface (preferably the outer peripheral portion of the inner bottom surface) of the bottom 34 of the container 3. If it is, it will not be specifically limited, Depending on the magnitude | size of the container 3, it can be 110 mm or more and 190 mm or less, for example.

  The thickness of the volatilization body 4 is not particularly limited, but the thinner one is not conspicuous in appearance when the drug volatilizer 1 is visually recognized from the outside, and is preferable from the viewpoint of design, but is thin. Since it will become easy to bend when too large, it is preferable to set it as 1.0 mm or more and 4.0 mm or less. In addition, the thickness of the volatilization body 4 can be defined by the diameter of a circle in which the cross section of the volatilization body 4 is inscribed.

  As shown in FIG. 2, the volatilizer 4 is a fine channel that is a channel through which the liquid drug 2 is sucked up in the longitudinal direction so that the liquid drug 2 can be sucked up by capillary action as shown in FIG. 2. A plurality of streak-like grooves 40 are provided on the outer periphery at intervals in the circumferential direction. The volatilizing body 4 includes a shaft portion 41 and a plurality of protrusions 42 protruding from the outer peripheral surface of the shaft portion 41 and extending in the longitudinal direction on the outer peripheral surface of the shaft portion 41, and between the adjacent protrusions 42 in the circumferential direction. There is a groove 40 in the groove. The outer shape of the cross section of the shaft portion 41 is not necessarily circular, and may be various shapes such as an elliptical shape, a polygonal shape such as a triangular shape or a quadrangular shape. The shape of the protrusion 42 (the shape of the groove 40) is not particularly limited, but in the present embodiment, the plurality of protrusions 42 radially spread from the center of the shaft portion 41. Therefore, the interval (circumferential length) between the adjacent protrusions 42 gradually increases toward the top part 42A of the protrusions 42. In other words, the width of the groove 40 extends from the groove bottom 40A to the external space side. It gradually spreads as it heads.

  The width (width at the groove bottom 40A) W of the volatilization body 4 is not particularly limited, but is 0.01 mm or more and 0.15 mm or less so that the liquid medicine 2 can be quickly sucked up at room temperature. It is preferable that Moreover, although the depth (height of the protrusion 42 from the outer peripheral surface of the axial part 41) H of the volatilization body 4 is not specifically limited, If the groove 40 is too deep, the protrusion 42 will be easy to bend. On the other hand, if the groove 40 is too shallow, the amount of the liquid medicine 2 that can be sucked is reduced, and when the hand or the like touches the volatilizing body 4, the hand or the like does not easily hit the protrusion 42 first, and the present invention described later. Therefore, it is preferable that the thickness be 0.1 mm or more and 1.0 mm or less.

  In addition to the plurality of grooves 40, the volatilizer 4 may include other flow paths that can suck up the liquid medicine 2 by capillary action. For example, by making the volatilization body 4 have a hollow structure, the cavity 43 extending in the longitudinal direction inside the volatilization body 4 can be used as a flow path for the liquid medicine 2. In this case, a fine groove may be further provided on the inner peripheral surface of the volatilizing body 4.

  The volatilization body 4 having the above-described configuration is formed of a material having high affinity with the liquid medicine 2. Since the volatilizer 4 is formed of a material having high affinity with the liquid drug 2, when the liquid drug 2 is sucked up by the respective grooves 40 of the volatilizer 4, the liquid drug 2 is deposited on the surface of the groove 40. It spreads so that the area where the liquid medicine 2 comes into contact with the surface of the groove 40 increases. Therefore, as shown in FIG. 3, when the liquid medicine 2 is sucked up in each groove 40 of the volatilization body 4, the liquid surface height of the liquid medicine 2 is greater than the depth (height of the protrusion 42) H of the groove 40. The liquid level of the liquid medicine 2 does not rise to the outer space side than the outer edge of the groove 40 (the top portion 42A of the protrusion 42). Therefore, when a hand, clothes, a curtain, or the like touches the upper end side portion exposed from the container 2 of the volatilizer 4, the top portion 42A of the protrusion 42 first touches the hand, and the liquid medicine 2 in the groove 40 becomes a hand. It becomes difficult to adhere to.

  If the volatilizer 4 is formed of a material having low affinity with the liquid drug 2, the liquid drug 2 is repelled on the surface of the groove 40 when the liquid drug 2 is sucked up by each groove 40 of the volatilizer 4. As a result, the liquid medicine 2 has a smaller area of contact with the surface of the groove 40. Therefore, as shown in FIG. 4, when the liquid medicine 2 is sucked up in each groove 40 of the volatilizer 4, the liquid level of the liquid medicine 2 becomes higher than the height H of the protrusion 42, and the liquid medicine 2 The liquid level rises to the outside space side from the top 42A of the protrusion 42. Therefore, when a hand, clothes, a curtain, etc. touch the part of the volatilization body 4 exposed from the container 2, the liquid chemical | medical agent 2 in the groove | channel 40 becomes easy to adhere to a hand etc.

  As the material having high affinity with the liquid drug 2, the liquid drug 2 has a contact angle α of 90 ° or less, preferably 70 ° or less, more preferably 50 ° or less, as shown in FIG. More preferably, the material is 30 ° or less, and more preferably 10 ° or less. This contact angle α is made of the material used for the volatilizer 4, and after removing dirt on the surface of the thin plate 5 (size: 60 mm × 20 mm, thickness: about 5 mm) having a flat surface, for example, using a micropipette. A liquid drug 2 droplet of about 6 μL is deposited on the surface of the thin plate 5, and the contact angle α of the liquid droplet after 1000 ms is measured with a contact angle meter (Kyowa Interface Chemical Co., Ltd .: DropMaster 500, measurement analysis integrated software: FAMAS). can do.

  Moreover, it is preferable that the volatilization body 4 of the structure mentioned above is formed with a transparent material. The transparent material may be either colorless or colored. When the volatilizing body 4 is formed of a transparent material, the outer peripheral surface of the volatilizing body 4 has a large number of surfaces that reflect light due to the plurality of grooves 40 on the outer periphery, and the light is irregularly reflected to shine as a whole. .

  As a material for forming the volatilization body 4 described above, for example, glass or transparent resin can be used. Examples of the transparent resin include polycarbonate, acrylic resin, polypropylene, polyethylene, low density polyethylene, vinylidene fluoride, Polyamide, polystyrene, vinyl chloride and the like can be preferably used. In addition, the material which forms the volatilization body 4 is not limited to these, A various material can be used if the contact angle (alpha) of the liquid chemical | medical agent 2 is 90 degrees or less.

  The volatilization body 4 can be formed by a general known molding method (for example, extrusion molding for a resin, for example, draw molding for glass, for example) using the material for forming the volatilization body 4 described above. The volatilization body 4 is preferably formed by extrusion molding or the like, and is preferably constituted of a single object (one rod-like body or plate-like body), and is a dense body with no or almost no gaps or holes. preferable. Thereby, since the volatilization body 4 is not substantially impregnated with the liquid medicine 2 inside, the volatilization body 4 is not in a state of holding the liquid medicine 2 excessively, and when the liquid medicine 2 disappears from the container 3, Since the liquid chemical 2 that the volatilizer 4 also immediately holds is lost, the end of use can be easily grasped. Moreover, in the volatilization body 4, since the flow path through which the liquid chemical | medical agent 2 passes other than the outer periphery groove | channel 40 and the internal cavity 43 can be eliminated, the suction speed of the liquid chemical | medical agent 2 by the volatilization body 4 is hold | maintained at a desired setting speed. be able to.

  As mentioned above, according to the volatilization body 4 of the structure mentioned above and the chemical volatilization device 1 using the said volatilization body 4, since the volatilization body 4 is formed with the material with high affinity with the liquid chemical | medical agent 2, the volatilization body 4 is formed. When the liquid medicine 2 is sucked up in each groove 40, the liquid surface of the liquid medicine 2 does not rise to the outside space side from the top 42 A of the protrusion 42, as shown in FIG. It passes through a deep space. Therefore, even if a hand, clothes, a curtain, or the like touches the upper end portion exposed from the container 2 of the volatilizing body 4, the top portion 42A of the protrusion 42 first touches the hand, so the liquid medicine 2 in the groove 40 Is difficult to adhere to the hand or the like, and the hand or the like can be prevented from being stained with the liquid medicine 2.

  In addition, when the volatile body 4 is formed of a transparent material, the outer peripheral surface of the volatile body 4 reflects more light due to the plurality of grooves 40 on the outer periphery, so that it appears to shine as a whole. Therefore, the beauty of the chemical volatilizer 1 can be improved, and the interior property of the chemical volatilizer 1 can be enhanced. Further, even if the liquid medicine 2 is colored, the colored liquid medicine 2 sucked up in each groove 40 becomes difficult to visually recognize because the volatilizer 4 shines brightly. Therefore, it can be seen that the volatilization body 4 does not change so much as before the liquid medicine 2 is sucked up, and the volatilization body 4 does not appear to be wet with the liquid medicine 2. In addition, if the volatilization body 4 is formed with a colorless and transparent material, the said effect can be suitably exhibited irrespective of the color of the liquid chemical | medical agent 2. FIG.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning.

  For example, in the above embodiment, the plurality of protrusions 42 have the same height H, but a plurality of kinds of protrusions having different heights may be combined. Further, the top portion 42A of each protrusion 42 may be branched into, for example, a Y shape in a cross sectional view.

  Moreover, in the said embodiment, although the volatilization body 4 is formed with the transparent material, it does not necessarily need to be formed with the transparent material.

  Moreover, in the said embodiment, although the volatilization body 4 is provided with the cavity 43 as a flow path which sucks up the liquid chemical | medical agent 2 by a capillary phenomenon, the volatilization body 4 is good also as a solid structure which does not provide the cavity 43.
