Further, in a space where only a short time stays like a toilet, there is a problem that a scent is not felt or a deodorizing function is not felt depending on the release timing.

Japanese Patent No. 4556209 Special No. 4870925

  Therefore, the main problem of the present invention is to provide a drug volatilization device that can be easily adjusted for sustained release, can release a scent of a desired strength and deodorization effect continuously for a long period of time, and has excellent flexibility in shape. There is to do.

  The present invention that has solved the above problems is as follows.

The drug body has a base layer containing the drug and a coating layer disposed on both sides of the base layer, and the coating layer on one side of the base layer is the base layer in the base layer. The drug weakly permeable layer that suppresses the volatilization of the drug, and the coating layer on the other surface side is the drug weakly permeable layer or the drug barrier layer that prevents volatilization of the drug in the base material layer, and the base material layer Is a flexible sheet-like and band-like drug film that is recognizable from the outside and is colored with a color-changing ink that changes color according to a decrease in at least one of the fragrance and deodorant,
The drug film is wound tightly without gaps, and the drug film is fed out from a take-up roll whose layer is not exposed to a predetermined length, and rewinded at a position away from the take-up roll. In addition, the winding roll, the rewinding portion, and the film surface between them are arranged in parallel to the flow direction of the airflow discharged from the discharge port, and on the discharge port of the base unit It is supported and fixed so that it can be replaced.
A chemical volatilization device characterized by that.

[Invention of Claim 2 ]

The chemical volatilization device according to claim 1 or 2, wherein the airflow generated by the generator is discharged from the opening through the periphery of the chemical body.

(Function and effect)
The chemical volatilization apparatus according to the present invention includes a chemical substance containing at least one of a deodorant and a fragrance, a coating body on both surfaces of the base material layer containing the chemical, and one of the chemical weakly permeable layers. And the other is formed using a drug film having a weak drug permeable layer or a drug barrier layer. Therefore, in the drug body according to the present invention, the fragrance and the deodorizing component in the base material layer pass through the weak drug permeable layer and are volatilized gently to the outside, and are not volatilized to the outside through the drug barrier layer.

  Therefore, the chemical volatilization apparatus according to the present invention is such that active ingredients such as fragrances and deodorant components are gradually volatilized to the outside as compared with those where the fragrance or deodorant is exposed. The scent of desired strength can be continuously released over a long period of time. Moreover, the intensity | strength of a fragrance and the duration of an effect can be designed easily by adjusting the permeability | transmittance of active ingredients, such as a gas permeability and thickness of a chemical | medical agent weak permeable layer.

  Furthermore, since the drug film is a flexible sheet, various drug body shapes can be formed by cutting, folding, winding, or the like without the need for a mold or the like. Moreover, the conventional chemical volatilization apparatus which accommodated the liquid and the gel has the limited exposure area which contacts external air on the relationship which accommodates the liquid and the gel in a container. For example, if it is a liquid, it will be limited to a liquid level. However, the drug film according to the present invention can widen the exposed area of the drug weakly permeable layer in a limited space by folding or the like or cutting adhesion. For this reason, the chemical volatilization device according to the present invention is compact and has a high degree of freedom in shape. In addition, since the surface area of the drug body can be accurately adjusted, the sustained release property can be accurately controlled by the surface area.

  The degree of freedom of compactness and design is difficult, for example, with a liquid or gel-like drug body, and can be made thin. In addition, in the case of a liquid or gel-like drug body, it is necessary to provide an opening at a position where it does not leak out, but the drug body according to the present invention does not leak. It can also be set as forms, such as a suspended form provided with the part, a wall hanging form, and a stationary form.

  On the other hand, the chemical volatilization apparatus according to the present invention is such that the fragrance or deodorant component of the base material layer is volatilized to the outside or the deodorizing function is exhibited through the chemical weakly permeable layer. However, if an airflow generating means for generating an airflow toward the drug body is further provided, the diffusibility of the aroma and deodorant component is improved.

  In addition, the container includes a container for storing the drug body, an opening formed in the container, and an airflow generation means for generating an airflow in the container, and the drug body is disposed between the opening of the container and the airflow generation means. If the airflow generated by the airflow generator is configured to be discharged from the opening through the periphery of the drug body, the fragrance and deodorant components volatilized from the drug body can be diffused efficiently and with directionality from the opening. Will be able to.

  In the case of providing the air flow generating means, it is desirable that the surface of the drug film constituting the drug body is arranged in parallel to the flow direction of the air flow. In this way, the aroma and deodorant component emitted from the drug body can be efficiently diffused without the drug body blocking the air flow generated by the air flow generator.

In forming a drug body with a drug film, the drug film can be loosely wound in a spiral shape into a cylindrical shape . If it does in this way, the exposed surface of many medicine films can be secured in a small space, which contributes to downsizing of the apparatus. In the case of this form, the drug body is disposed between the opening of the container and the airflow generating means by disposing the opening and the airflow generating means in the direction of both end faces of the cylinder, and the drug body The surface of the drug film constituting the film is arranged in parallel with the flow direction of the airflow, and the odor and deodorant components are extremely excellent in diffusibility to the outside, and the apparatus is also made compact.

Further, since the drug body is composed of a drug film , the drug body can be formed by zigzag folding the drug film. A thin drug body can be formed while ensuring a large exposed area of the drug film. This makes it easier to design a thin drug volatilization device.

In addition, since the drug body is composed of a drug film , the drug body can be a drug film in which a large number of holes are formed with a plurality of intervals. If it does in this way, the chemical | medical body which an airflow can pass through a hole can be formed. Therefore, it becomes a chemical volatilization device which is excellent in fragrance diffusibility, particularly in combination with an airflow generation device.

Further, since the drug body is composed of a thin sheet-like drug film, it can be folded like origami, or cut into an appropriate part and bonded to be processed. Therefore, for example, it can be formed into a three-dimensional shape or a geometric three-dimensional shape imitating animals and plants like artificial flowers, or a part thereof, and in this case, the drug body has excellent design properties.

Here, the drug volatilization apparatus according to the present invention is configured to rewind the drug body at a position separated from the take-up roll by feeding a drug film of a predetermined length from a take-up roll obtained by winding a band-shaped drug film. It is configured to take a picture . In the drug body, when the winding of the take-up roll is made dense, the drug film is exposed only in the part from the outer surface to the rewinding. Therefore, when the fragrance and deodorant property of the exposed part is lowered, when this part is re-wound, a new drug film is unwound from the take-up roll and exposed, and the scent and deodorant part are exposed. Will feel again.

  In the form of this take-up roll, if the take-up roll is taken up in such a manner that the drug film whose coating layer on one side is a barrier layer is taken up so that the barrier layer becomes the outer face of the take-up roll, The body surface (outer peripheral surface) of the roll is protected by the barrier layer. Volatilization of the fragrance | flavor and the deodorizing component from the trunk | drum surface of a winding roll can be prevented.

On the other hand, the chemical volatilization device of the present invention includes a blower, and a fan of the blower is formed of a chemical body . If it does in this way, the fragrance and deodorant component which generate | occur | produced from the fan can be diffused as an airflow as it is. Since the medicine body concerning the present invention is formed with a sheet-like medicine film, it can be used as a fan of an air blower in this way.

  As described above, according to the present invention, there is provided a drug volatilization device that can be easily adjusted for sustained release, can release a scent or deodorant with a desired strength continuously for a long period of time, and is excellent in shape flexibility. Provided.

Embodiments and reference embodiments of the present invention will be described in detail below with reference to FIGS.

  The drug volatilization apparatus according to the present embodiment has a drug body that volatilizes a fragrance or a deodorant component to release a scent, and the drug body is characteristically formed from a drug film.

[Drug film]
As shown in FIG. 1, a drug film 1 forming a drug body according to this embodiment is disposed in contact with both a base material layer 10 containing a drug that is at least one of a fragrance and a deodorant and both surfaces of the base material layer. The coating layer 11, 12 is a coating layer 11 on one side of the coating layers 11, 12 is a weakly permeable drug layer 11 that suppresses the volatilization of the drug in the base material layer, The coating layer 12 on the other side has a laminated structure in which the drug barrier layer 12 prevents the drug in the drug weakly permeable layer or the base material layer from being volatilized. An example of the permeable layer 11 and the other side of the drug barrier layer 12 is shown).

  The base material layer 10, the drug weakly permeable layer 11 and the drug barrier layer 12 are not necessarily a single layer, and may be a layer composed of a plurality of layers as long as the function is not hindered. For example, the side opposite to the base material layer 10 side of the drug weakly permeable layer 11 or the drug barrier layer 12 may be a layer having high heat-fusibility so that the drug film can be easily heat-sealed to the object, or paper Alternatively, a woven fabric or a non-woven fabric may be laminated and bonded to express these material feelings to enhance the design.

  As a specific example of the layer structure of the drug film 1 according to the present embodiment, the drug weakly permeable layer 11 and the drug barrier layer 12 are made of resin films having different gas permeability, and the base material layer 10 bonds them together. The base layer 10, the drug weakly permeable layer 11 and the drug barrier layer 12 are all resin film layers, and the drug weakly permeable layer 11 and the drug barrier layer 12 are gas permeable. Examples of the layer structure include: resin films having different properties, and the base material layer 10 is made of a resinous film containing a fragrance positioned between them.

  The flexibility or rigidity of the drug film 1 according to this embodiment can be appropriately designed depending on the shape of the drug body to be molded. For example, if the drug body is self-supporting, it should be flexible and slightly rigid, and if the drug body is formed so as to follow a support having a complicated shape, shape follow-up It should be highly flexible to enhance the performance. The rigidity and flexibility of the drug film can be designed according to the material of each layer and the thickness of each layer.

  The thickness of the drug film 1 according to the present embodiment is desirably 15 to 200 μm, and more desirably 45 to 145 μm. When the thickness is less than 15 μm, it is difficult to secure the formable strength while having the functions of the base material layer 10 and the drug barrier layer 12 of the drug weakly permeable layer 11. If it is less than 15 μm, it will be difficult to secure sufficient strength to form a drug body while having the functions of the base material layer 10 and the drug barrier layer 12 of the drug weakly permeable layer 11. Even if it exceeds 200 μm, the improvement in the design of each layer due to the increase in thickness is poor, and the cost is rather high. Here, the method for measuring the film thickness of the drug film 1 is that after the test piece is fully conditioned under the conditions of JIS P 8111 (1998), a dial thickness gauge (thickness measuring instrument) “PEACOCK” is used under the same conditions. Measured using "G type" (manufactured by Ozaki Seisakusho). The load at the time of measuring the thickness is about 70 gf at 120 μm. The thickness is an average value obtained by performing measurement 10 times.

  On the other hand, the drug film 1 according to the present embodiment may be transparent or opaque. It can select according to the design property of the chemical | medical agent body shape | molded. Alternatively, the weakly permeable drug layer 11 and the drug barrier layer 12 may be transparent or opaque so that the base material layer 10 can be recognized from the outside, and only the base material layer 10 may be colored. In that case, the indicator function of the replacement time can be imparted using a color-changing ink that changes in accordance with a decrease in the active ingredient contained in the base material layer. As the color changing ink that changes in accordance with the decrease in the fragrance and deodorant component contained in the base material layer, the pH of the base material layer 10 due to the decrease in the fragrance contained in the base material layer, such as a cochineal pigment or an acid-base indicator. The thing which changes color according to a change can be illustrated.

(Medium weakly permeable layer)
The drug weakly permeable layer 11 constituting the drug film 1 according to the present embodiment is a layer that covers the base material layer 10 and allows perfume and deodorant from the base material layer 10 to permeate, but the volatilization thereof. It is a layer that adjusts the volatility and sustainability of the drug compared to the state in which the base material layer 10 is exposed by suppression.

The drug weakly permeable layer 11 is preferably a resin film layer having an oxygen permeability of 700 cc / m ² · 24 h / atm or more and a carbon dioxide gas permeability of 4000 cc / m ² · 24 h / atm or more.

Suitable examples of the resin film layer for forming the drug weakly permeable layer include a polyethylene film layer, a polystyrene film layer, a polypropylene film, and a polycarbonate film layer, and can be appropriately selected in relation to the fragrance used. it can.

(Drug barrier layer)
On the other hand, the drug barrier layer 12 constituting the drug film 1 according to the present embodiment is a layer that has extremely low drug penetration and prevents the drug from the base material layer from being substantially volatilized.

The drug barrier layer 12 is a resin film layer having an oxygen permeability of less than 200 cc / m ² · 24 h / atm and a carbon dioxide gas permeability of less than 900 cc / m ² · 24 h / atm. Is desirable. If it is the resin-made film layer which has the said gas permeability, it will become possible to prevent volatilization of a fragrance | flavor suitably.

  Examples of suitable resin film layers include polyethylene terephthalate film layers, polyvinylidene chloride film layers, EVOH resin film layers (ethylene-vinyl alcohol copolymer film layers) such as Eval manufactured by Kuraray Co., Ltd., and EVOH resins. Examples thereof include a film layer made of a resin blended with a styrene elastomer, and can be appropriately selected in consideration of the aroma retaining property used from these. Moreover, a chemical | medical agent barrier layer can also be comprised with metal sheets, such as metal foil, or the laminated film which laminated | stacked this.

The aspect made into the resin film layer by which the chemical | medical agent was kneaded laminated | stacked on the resin film layer can be illustrated.

  When the base material layer 10 is formed as an adhesive layer, the adhesive base makes it impossible to peel off the resin film constituting the drug weakly permeable layer 11 and the resin film or metal foil constituting the drug barrier layer 12. For example, a natural rubber adhesive, a natural rubber latex adhesive, an acrylic adhesive, a hot melt adhesive, and the like. When the adhesion surface of the weak drug permeable layer and the drug barrier layer to the base material layer is a resin film, the acrylic adhesive is particularly excellent in the adhesion of the resin film sheet and in the perfume solubility / dispersibility. Agents are preferred.

  When the base material layer 10 is formed as an adhesive layer, the base material layer 10 may be present between the weakly permeable drug layer 11 and the drug barrier layer 12 in a scattered manner or in a pattern, but preferably the entire surface. It is desirable to have an embodiment interposed in The integrity of the drug weakly permeable layer 11 and the drug barrier layer 12 is enhanced.

The blending ratio of the drug in the pressure-sensitive adhesive layer can be determined by the type and volatility of the fragrance and deodorant. terms, 0.5~15g / m ^2, it's good especially 3 to 8 g / m ^2.

  On the other hand, when the base material layer 10 is formed as a resin film layer kneaded with a drug, the base resin of the resin film layer is preferably a rubbery block copolymer having a styrene block and a diene block. Such rubbery block copolymers include styrene-butadiene copolymers, styrene-isoprene copolymers, styrene-butadiene-styrene copolymers, styrene-isoprene-styrene copolymers, styrene-isoprene-butylene-styrene copolymers. Examples thereof include polymers, styrene-ethylene-propylene-styrene copolymers, and hydrogenated products thereof. These may be used alone or in combination of two or more as the base resin.

  In addition, the base resin may be obtained by blending polyethylene, polypropylene, polyethylene or a maleic anhydride-modified product of polypropylene or an ethylene-vinyl copolymer with the rubbery block copolymer.

  When the base material layer is formed as a resin film layer kneaded with a drug, 1 to 50% by weight of the drug can be mixed in the base resin.

On the other hand, as the fragrance contained in the base layer, known natural or synthetic fragrances can be used. Specific examples include natural perfumes such as lemon oil, grapefruit oil, rosemary oil, peppermint oil, mandarin oil, lime oil, yuzu oil, chamomile oil, lavender oil, rose oil, spearmint oil; alcohol, ketone, aldehyde; limonene , Synthetic fragrances of terpenes such as linalool, citronellol, menthol and geraniol. These may be used alone or in combination as a blended fragrance. The selection of the fragrance may be determined according to the desired fragrance tone.
Moreover, a fragrance | flavor can be diluted using vegetable oils, such as mineral oil, such as dipropylene glycol and paraffin oil, a castor oil, and soybean oil, in order to adjust the intensity | strength of fragrance.

  On the other hand, the thickness of the base material layer 10 which concerns on this embodiment is 5-100 micrometers, More preferably, it is 30-80 micrometers. Within this range, the sustained release can be adjusted with the thickness without excessively thickening the entire drug film.

  Further, the drug film according to the present invention includes a nitrogen compound system such as trimethylamine, hydrogen sulfide, methylcaptan, which is a malodorous component that floats in a base layer together with a fragrance or in an indoor space such as a toilet space instead of the fragrance. A deodorant for deodorizing sulfur-based compounds such as When the deodorant is contained together with the fragrance, the deodorant is selected so as not to affect the fragrance and to evaporate to the outside from the weakly permeable layer of the drug together with the fragrance.

  The deodorant according to the present invention is preferably a chemical deodorant component that can permeate the drug weakly permeable layer. Specific examples include polyphenol deodorants such as polyphenols and polyphenol derivatives, betaine compound deodorants, and grafts. Copolymer deodorant, surfactant deodorant and the like. In order to increase these volatility, an appropriate volatilization auxiliary may be contained. A combination of deodorants can be appropriately selected from known ones.

(Example of drug film production method)
In the drug film 1 according to this embodiment, the base material layer 10, the drug weakly permeable layer 11, and the drug barrier layer 12 can be laminated by a co-extrusion method using the T-die method, an extrusion lamination method, or a dry lamination method. The thickness of each layer is preferably 5 to 100 μm for the base layer 10, 5 to 50 μm for the weak drug permeable layer 11, and 5 to 50 μm for the drug barrier layer 12. The function of each layer can be sufficiently secured without impairing the moldability and flexibility of the drug film as a whole. In addition, the specific thickness of each layer can be suitably changed according to the desired sustained release property of a fragrance | flavor or a deodorizer.

  When the base material layer 10 is formed as an adhesive layer, a film sheet related to the weakly permeable drug layer 11 or the drug barrier layer 12 is formed, and then laminated and integrated with an adhesive containing a fragrance in advance by a dry laminating method. You just have to do it.

  When the substrate layer 10 is a resin film layer, the resin for forming the weakly permeable drug layer 11, the resin for forming the drug barrier layer 12, and the above base resin containing a fragrance are co-extruded by the T-die method. Lamination or extrusion lamination method.

  In order to contain the drug in the base resin, there can be exemplified a method in which the drug is mixed and kneaded in advance with the base resin, and this is used as a material to form a film, and a method in which a perfume is injected during extrusion.

(Drug persistence adjustment method)

  As the air flow generation means, a known air flow generation device such as a known blower such as a sirocco fan, a cross flow fan, or a fan motor that can be driven by a DC power source or a pump mechanism that generates compressed air can be used. The generation of the air current may be configured to generate an air current constantly, or may be generated intermittently by driving a timer, or may be activated only when a human sensor is detected. May be. What is necessary is just to design the timing of airflow generation suitably by a well-known technique. Moreover, the strength (air volume) of the airflow generated by the airflow generating means is an appropriate design matter, and may be appropriately designed according to the compression ratio of the blower in consideration of the size of the installation space and the fragrance diffusibility.

On the other hand, the drug body 23 of the first reference form is formed by loosely winding a film obtained by cutting the drug film 1 into a belt shape, and forming it into a cylindrical shape. It has a characteristic shape. The drug body 23 is supported and fixed so as to be replaceable by inserting the air core portion into a support column portion 24 provided at the center of the upper surface of the base portion 22. However, the method for supporting and fixing the drug body is not limited to this form.

Therefore, in the drug volatilization apparatus 20 according to the first reference embodiment , the drug body 23 is supported and fixed on the exhaust port with the upper and lower end surfaces being in the vertical direction, and each surface of the drug body film 1 is in the airflow direction. They are positioned parallel to each other.

In the illustrated form, the drug film 1 cut into a rectangle is zigzag-folded, but it may be cut into a circle or an ellipse and zigzag-folded.

  The illustrated chemical volatilization device 30 is provided with a pair of drug body support portions 34, 34 at the edge of the base portion 22, and the drug body support portions 34, 34 are below the drug body 33 having the above shape. The edge portion is inserted and supported and fixed in a replaceable manner so that each surface of the drug body film 1 is positioned parallel to the flow direction of the airflow. In the illustrated form, the drug body itself using the somewhat rigid drug film 1 is self-supporting. However, if the drug film is highly flexible, it is difficult to use a hard metal such as metal or engineering plastic. A support frame may be formed, and the drug body may be fixed to the support frame so that the zigzag folded shape is maintained.

  The drug body device 30 of this embodiment also passes the periphery of the drug body 34 without the airflow from the exhaust ports 21, 21... Being obstructed by the drug body 33, and allows the aroma and deodorant emitted from the drug body 34 to be exposed to the outside. Effectively diffuse.

( 3rd reference form )
The chemical volatilization device 40 according to the third reference form is shown in FIG. The drug volatilization apparatus 40 according to the third reference form is different from the first and second reference forms in the shape of the drug body 43 and its support mode. A description overlapping with the first and second reference embodiments will be omitted.

In the third reference embodiment , as shown in FIG. 4, a plurality of drug films 1, 1... Cut into a strip-like elongated shape are arranged side by side in parallel to form a drug body 43. In the present embodiment, the drug film 43A constituting the drug body 43 is designed to be light and flexible by reducing the thickness, so that the drug film 43A flutters from the exhaust ports 21, 21. In the present embodiment, for example, the drug body 43 can feel movement.

Also in the third reference form , the drug film 43A may be either the drug weakly permeable layer 11 on both the front and back surfaces or the drug barrier layer 12 on one side.
