[Brief description of the drawings]
[0011] [Figure 1] 1A and 1B are a front view and a cross-sectional view showing the structure of a fragrance device according to a first embodiment. [Diagram 2] 11A and 11B are a front view and a cross-sectional view showing the structure of a fragrance device according to a second embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] Hereinafter, with reference to the drawings, an embodiment of the present invention will be described using an aroma device used for deodorizing and aromatizing a toilet as an example. The present invention is not limited to the specific embodiment shown below, and the form can be modified and carried out.
[0013] As shown in Fig. 1, fragrance device 10 comprises cover 11 and fragrance retention member 12. Cover 11 and fragrance retention member 12 are integrated, and fragrance device 10 is used in this integrated state. Cover 11 and fragrance retention member 12 may be configured to be separable. Fragrance device 10 is used by being attached and fixed to, for example, a toilet tank or a washbasin, and releases a fragrance (fragrance component) into the air. Fragrance device 10 may comprise members other than cover 11 and fragrance retention member 12.
[0014] The specific form of the cover 11 is not particularly limited. Preferably, the cover 11 is provided with a plate-like portion. Typically, the plate-like portion is flat, but may be curved. Although not essential, in this embodiment, the entire cover 11 is plate-like. Also, although not essential, the cover 11 may be provided with a frame-like portion so as to surround the fragrance-holding member 12 described below. Also, although not essential, the cover 11 may be elastic and deformable.
[0015] The fragrance holding member 12 contains a fragrance component. The specific form of the fragrance holding member 12 is not particularly limited. Preferably, the fragrance holding member 12 is plate-shaped. As in this embodiment, if the plate-shaped fragrance holding member 12 is laminated on the plate-shaped portion of the cover 11, the fragrance device 10 can be made lightweight and compact, which is preferable.
[0016] The cover 11 is made of silicone rubber or silicone resin. The silicone rubber is not particularly limited, but examples thereof include silicone rubber such as KE series from Shin-Etsu Chemical Co., Ltd. The silicone resin is not particularly limited, but examples thereof include KR series from Shin-Etsu Chemical Co., Ltd. The cover 11 and the fragrance holding member 12 described below may be formed by mixing silicone rubber and silicone resin. The silicone rubber may be blended with silicone resin. The silicone resin may be blended with silicone rubber. In other words, the term "silicone rubber or silicone resin" in this specification includes a mixture of silicone rubber and silicone resin.
[0017] The silicone rubber or silicone resin constituting the cover 11 is not particularly limited as long as it maintains the shape of the cover. The silicone rubber or silicone resin constituting the cover 11 may be crosslinked, partially crosslinked, or substantially uncrosslinked. From the viewpoint of reliably maintaining the shape of the cover 11 and making the cover non-sticky and easy to handle, it is preferable that the silicone rubber or silicone resin constituting the cover 11 is crosslinked.
[0018] The fragrance holding member 12 containing the fragrance component is made of silicone rubber or silicone resin. The fragrance holding member 12 has adhesiveness or tackiness. The cover 11 is supported by the fragrance holding member 12 due to the adhesiveness or tackiness of the fragrance holding member 12.
[0019] Any fragrance component can be contained in the fragrance holding member 12 so as to obtain a desired fragrance. Although not essential, a fragrance containing any of β-citronellol, 4-tert-butylcyclohexyl acetate, allyl heptanoate, CIS-3-hexenyl acetate, allyl hexanoate, and calone is preferably added as the fragrance component.
[0020] These flavor components may be preliminarily kneaded into the silicone rubber or silicone resin that constitutes the flavor retention member 12. Alternatively, the flavor components may be incorporated into the flavor retention member 12 by applying the flavor components to the flavor retention member 12 formed from silicone rubber or silicone resin, or by immersing the flavor retention member 12 in a liquid that contains the flavor components.
[0021] The silicone rubber or silicone resin constituting the fragrance holding member 12 is not particularly limited, and may be cross-linked, partially cross-linked, or substantially non-cross-linked. The silicone rubber or silicone resin constituting the fragrance holding member 12 has adhesiveness or tackiness to such an extent that the fragrance holding member 12 can be attached to and supported by the plate-like portion of the cover 11. The silicone rubber or silicone resin constituting the fragrance holding member 12 may contain a liquid component such as silicone oil for increasing adhesiveness, a tackifier, a filler material, a modifier, etc. Although not essential, a preferred range of adhesiveness or tackiness of the fragrance holding member 12 is, for example, approximately 0.1 to 10 N / 5 mmφ when measured using a probe tack test method (contact pressure 20 g / cm2, probe speed 1 cm / sec, contact time 1 sec, room temperature 23 to 25°C).
[0022] Although not essential, it is preferable that fragrance holding member 12 is made of uncrosslinked silicone rubber or silicone resin. Uncrosslinked silicone rubber or silicone resin is easily deformed, and the resin has high adhesiveness, which makes it easier for fragrance holding member 12 to adhere to the plate-like portion of cover 11. It is particularly preferable that uncrosslinked silicone rubber or silicone resin has plasticity. If fragrance holding member 12 has plasticity, fragrance holding member 12 can adhere well to the shape of cover 11 and the shape of the surface to which fragrance device 10 is attached.
[0023] Furthermore, although not essential, when the fragrance holding member 12 is made of uncrosslinked silicone rubber or silicone resin, the uncrosslinked silicone rubber or silicone resin constituting the fragrance holding member 12 preferably has a Williams plasticity of 60 to 500. It is particularly preferable that the Williams plasticity is 100 to 300. If the uncrosslinked silicone rubber or silicone resin has such a plasticity, the fragrance holding member 12 will adhere particularly easily to the plate-shaped portion of the cover 11 and the surface to which the fragrance device 10 is attached.
[0024] The Williams plasticity index is based on the international standard ISO7323 and is calculated by multiplying the thickness of a cylindrical specimen having a diameter of 16 mm and a height of 10 mm by 100, the thickness being measured a predetermined time after pressing (5 minutes in this specification) using a parallel plate plasticity tester at a predetermined temperature (room temperature of 23°C in this specification) to a final load of 49 N.
[0025] Although not essential, in this embodiment, the flavorant holding member 12 is plate-shaped. A plate-shaped flavorant holding member 12 can be brought into contact with the cover 11 over a wide area with a small amount of flavorant holding member. The external shape of the plate-shaped flavorant holding member 12 is not particularly limited, and may be rectangular as in this embodiment, or may be other shapes such as circular or the shape of a character.
[0026] The fragrance-retaining member 12 can be manufactured, for example, by kneading additives such as fragrance components and silicone oil into a millable-type uncrosslinked silicone rubber to produce an uncrosslinked rubber material, and then molding the uncrosslinked rubber material into a sheet. These processes are known. If the fragrance-retaining member 12 is crosslinked, a crosslinking process may be added to the process of molding the fragrance-retaining member 12 or a subsequent process. The molding process of the fragrance-retaining member 12 may utilize injection molding as well as roll molding and press molding.
[0027] The silicone rubber or silicone resin constituting the fragrance holding member 12 may be one that is capable of maintaining its solid shape, i.e., one that does not substantially have plasticity. Examples of means for maintaining the solid shape include crosslinking, partial crosslinking, gelation, etc.
[0028] When the silicone rubber or silicone resin constituting the fragrance holding member 12 is capable of maintaining its shape as a solid, the silicone rubber or silicone resin preferably has a durometer A hardness of 10 to 50 degrees measured with a type A durometer conforming to JISK-6253, and preferably has an Asker C hardness of 20 to 70 degrees as specified in the Society of Rubber Industry Standards (SRIS 0101). When the hardness of the silicone rubber or silicone resin is within this range, the fragrance holding member 12 is particularly likely to adhere to the plate-like portion of the cover 11.
[0029] A part of the fragrance device 10 is exposed to the fragrance holding member 12. Although not essential, in this embodiment, one surface of the plate-shaped fragrance holding member 12 is in close contact with the cover 11, and the other surface of the fragrance holding member 12 is exposed. Since the fragrance holding member 12 has adhesiveness or tackiness, the adhesiveness or tackiness of the exposed part of the fragrance holding member 12 can be used to attach the fragrance device 10 to various locations.
[0030] When using fragrance device 10, fragrance device 10 can be attached to a wall surface, an article, or the like. For example, fragrance device 10 can be attached to the tank of a toilet, a wall or glass window in a kitchen, or the housing of a home appliance such as a refrigerator or television. If the adhesive strength is sufficiently high, it can also be attached to a ceiling or the cover of a ceiling light. Alternatively, fragrance-holding member 12 can be placed at the boundary between a wall surface and a shelf, and attached to the wall surface so that the member does not fall over. Fragrance device 10 can also be attached to the dashboard of a car. Fragrance device 10 can also be attached to a bag or a mobile information terminal (such as a smartphone).
[0031] When the fragrance device 10 is used, the fragrance component contained in the fragrance holding member 12 moves to the cover 11 supported by the fragrance holding member 12, and the fragrance component is gradually diffused into the atmosphere through the cover 11, thereby releasing a fragrance.
[0032] A method for manufacturing the aroma device 10 will now be described. The cover 11 is molded from silicone rubber or silicone resin by means of, for example, injection molding, press molding, etc. Preferably, the silicone rubber or silicone resin is crosslinked when molded so that the shape of the member does not change during use. On the other hand, the perfume-holding member 12 is manufactured by the above-mentioned method.
[0033] The fragrance holding member 12 is attached to a predetermined position of the cover 11. When the fragrance holding member 12 and the cover 11 are brought into contact and pressed together, the cover 11 is supported by the fragrance holding member 12 due to the adhesiveness or tackiness of the fragrance holding member 12. When the cover 11 and the fragrance holding member 12 are integrated, the fragrance device 10 is completed. The degree of support may be such that the cover 11 does not fall off the fragrance holding member 12 when the fragrance device 10 is used.
[0034] The operation and effect of the aroma device 10 will now be described. According to the fragrance device 10 of the above embodiment, the fragrance device 10 can be easily attached to various locations by utilizing the adhesiveness or tackiness of the fragrance holding member 12. Moreover, according to the fragrance device 10, the cover 11 and the fragrance holding member 12 are made of the same type of resin, namely silicone rubber or silicone resin, and the cover 11 is supported by the fragrance holding member 12, so that the fragrance component contained in the fragrance holding member 12 gradually migrates to the cover 11 made of silicone rubber or silicone resin through the contact area between the two, and is diffused into the atmosphere through the cover 11, resulting in excellent sustained release of the fragrance (fragrance component).
[0035] The sustained release of the fragrance can be adjusted by the thickness of cover 11 and the shape of the surface of the cover that faces the air. For example, if the thickness of cover 11 is increased, the fragrance that is diffused will be gentler and the fragrance will last longer. Also, if the surface area is increased by providing the surface of the cover with irregularities, holes, ridges, grooves, etc., the fragrance that is diffused will be stronger and the period during which the fragrance lasts will be somewhat shorter.
[0036] Furthermore, when the fragrance holding member 12 is made of uncrosslinked silicone rubber or silicone resin, the fragrance holding member 12 has plasticity, and can flexibly conform to the shape of the surface to which the fragrance device 10 is to be attached, whether the surface is flat, curved, or has some unevenness, making it easier to attach the fragrance device 10 to various locations. Furthermore, when the fragrance holding member 12 is made of uncrosslinked silicone rubber or silicone resin, the fragrance holding member 12 adheres closely to the cover 11, improving the movement of the fragrance component between the two, and the fragrance component contained in the fragrance holding member 12 can be gradually released by the cover 11 without being left over.
[0037] Furthermore, when the Williams plasticity number of the uncrosslinked silicone rubber or silicone resin constituting the fragrance holding member 12 is 60 to 500, it becomes particularly easy to attach the fragrance device 10 to various locations, and it becomes easier to gradually release the fragrance components contained in the fragrance holding member 12 by the cover 11 without leaving any excess.
[0038] Furthermore, if the cover 11 has a plate-like portion, the fragrance holding member 12 is plate-like, and the plate-like portion and the fragrance holding member 12 are laminated, the fragrance device becomes lightweight and compact, making it easier to attach the fragrance device 10 to various locations.
[0039] The invention is not limited to the above-mentioned embodiment, and can be practiced with various modifications. Other embodiments of the invention will be described below, but in the following description, the differences from the above-mentioned embodiment will be mainly described, and detailed descriptions of similar parts will be omitted. In addition, these embodiments can be practiced by combining parts with each other or by replacing parts.
[0040] In the above description of the embodiment, an example of support in which the plate-shaped flavorant holding member 12 adheres to the plate-shaped portion of the cover 11 has been shown, but the flavorant holding member 12 may have other shapes, such as a hemisphere, a pyramid, a prism, a cylinder, a rectangular parallelepiped, etc., as long as it can sufficiently contact and adhere to the plate-shaped portion. Preferably, the shape of the flavorant holding member 12 has a flat surface.
[0041] Furthermore, when the fragrance-retaining member is plastic, such as being uncrosslinked, the shape of the fragrance-retaining member is not particularly limited, since a sufficient contact surface can be secured when the fragrance-retaining member comes into contact with the cover 11. If the fragrance-retaining member is plate-shaped, this is preferable because it is easy to handle during use and storage of the fragrance-retaining member.
[0042] It is possible to appropriately change the type and combination of fragrance components contained in the fragrance retention member 12. For example, a plurality of types of fragrance retention members 12, 12 with preferred fragrance types and images, such as green, floral, citrus, musk, etc., may be prepared, and a fragrance device 10 with the desired fragrance may be manufactured by selecting a fragrance retention member according to the fragrance to be imparted.
[0043] In the fragrance device 10, the fragrance holding member 12 may be replaceable. That is, after the fragrance device 10 has been used and the fragrance component has run low, the fragrance retention member 12 can be removed from the cover 11 and replaced. At that time, the fragrance retention member 12 may be replaced with a fragrance retention member 12 containing the same fragrance component as the original fragrance component, thereby replenishing the fragrance component with the same fragrance, or it may be replaced with a fragrance retention member containing a fragrance component different from the original fragrance component, thereby changing the fragrance of the fragrance device 10 or blending fragrances.
[0044] Moreover, cover 11 is preferably made of silicone rubber or silicone resin that is substantially not sticky or tacky. If cover 11 is not sticky or tacky, dirt and dust are prevented from sticking to the cover when fragrance device 10 is used, and fragrance device 10 can be used hygienically.
[0045] FIG. 2 shows fragrance device 20 of a second embodiment. In this embodiment, cover 21 has a three-dimensional circular shape with a raised center. Also, as in this embodiment, cover 21 may be shaped like some kind of character. In this embodiment, fragrance holding member 22 is also plate-shaped, but the shape of fragrance holding member 22 may be dumpling-shaped or hemispherical, particularly when fragrance holding member 22 has plasticity. Even in such a form, fragrance device 20 can achieve the same effects.
[0046] The environment in which the fragrance devices 10 and 20 are used is not particularly limited. In addition to the toilets, rooms in homes such as living rooms, bathrooms, changing rooms, and washrooms, as already exemplified, and corridors and entrances, these fragrance devices can also be used in rooms and spaces in companies such as offices, work rooms, reception rooms, dining rooms, changing rooms, medical rooms, workshops, parking lots, and factories. These fragrance devices may be used in the interior of a car or on a motorcycle. These fragrance devices can also be used in commercial spaces such as supermarkets, department stores, clothing stores, shopping malls, and markets, as well as public spaces such as underground shopping malls, sidewalks, city halls, and libraries. The fragrance devices can also be attached to personal belongings such as belts, clothing, accessories, helmets, bags, pouches, and smartphones. [Industrial Applicability]
[0047] The fragrance device of the above embodiment has a high degree of freedom in terms of where it can be installed, and is highly industrially applicable. [Explanation of symbols]
