Abstract
Description
[Technical field]
[0001] The present invention relates to a fragrance material. [Background technology]
[0002] In recent years, aromatic materials containing liquid aromatic agents have been developed to provide a relaxing effect, a refreshing effect, an invigorating feeling, and the like, regardless of location. The aromatic materials are used as portable items, such as sprays and roll-ons. These portable items are large in volume, making it difficult to carry only the amount desired for use, such as a single dose.
[0003] For example, Patent Document 1 describes an invention related to an aromatic member that is mainly attached to a mask. The aromatic member described in Patent Document 1 has a configuration in which a capsule containing an aromatic agent is held in a recess in a base. Patent Document 1 describes that when the aromatic member is attached to a mask and the capsule is crushed, the aromatic agent contained in the capsule flows out and permeates the mask, and the aromatic agent evaporates, so that the aromatic component is inhaled into the nasal cavity and the scent can be enjoyed. Since one capsule is the amount used for one use, aromatic members can now be carried around more easily than with previous portable items. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Patent No. 7054277 Summary of the Invention [Problem to be solved by the invention]
[0005] According to the aromatic material described in Patent Document 1, although it is possible to obtain a relaxing effect due to the aromatic agent, the aromatic agent seeps into the mask (adherend) during use, which may make it difficult to reuse the adherend, and if the aromatic agent is colored, the color of the adherend may change, which may impair the appearance of the adherend. Also, since it is assumed that the aromatic agent will seep into the adherend, its uses may be limited.
[0006] In this situation, there is a demand for novel forms of fragrance materials. [Means for solving the problem]
[0007] The present invention includes, for example, the following aspects.
[0008] [1] A capsule-containing substrate having a substrate and a collapsible capsule containing a liquid fragrance held by the substrate; a first liquid barrier layer disposed on one side of the capsule-containing substrate; a second liquid barrier layer disposed on the other side of the capsule-containing substrate; The aromatic member has [2] The fragrance member according to [1] above, wherein the collapsible capsule is embedded in a substrate. [3] The fragrance member according to [1] above, wherein the collapsible capsule is exposed on at least one surface of the substrate. [4] The fragrance member according to [3] above, wherein the collapsible capsule is exposed on both sides of the base. [5] The fragrance member according to any one of the above [1] to [4], wherein at least one of the first liquid barrier layer and the second liquid barrier layer is an adhesive layer. [6] The fragrance member according to any one of the above [1] to [5], wherein at least one of the first liquid barrier layer and the second liquid barrier layer comprises an adhesive layer and a non-adhesive layer. [7] The aromatic member according to the above [6], wherein the adhesive layer exhibits liquid barrier properties. [8] The fragrance member according to the above [6] or [7], wherein the non-adhesive layer exhibits liquid barrier properties. [9] The fragrance member according to any one of the above [6] to [8], wherein the non-adhesive layer is made of a rigid plate-like member.
[10] The fragrance member according to any one of the above [1] to [9], wherein the liquid fragrance contains a plant extract.
[11] The aromatic material according to
[10] above, wherein the plant extract contains caryophyllene.
[12] The fragrance member according to any one of the above [1] to
[11] , which is attached to a mask, skin, clothing, shoes, or a bag. Effect of the Invention
[0009] According to the present invention, a novel aromatic member is provided. The aromatic member according to the present invention has at least one of the following advantages: the adherend can be reused because the liquid aromatic agent does not seep out onto the adherend; the appearance of the adherend is not impaired; and the adherend can be used for a variety of purposes.

[0011] Hereinafter, an embodiment of the present invention will be described in detail.
[0012] 1. Fragrance materials The fragrance member of one embodiment of the present invention comprises a capsule-containing substrate having a substrate and a collapsible capsule containing a liquid fragrance held by the substrate, a first liquid barrier layer disposed on one side of the capsule-containing substrate, and a second liquid barrier layer disposed on the other side of the capsule-containing substrate.
[0013] The present invention will be described below with reference to the drawings. Note that the drawings may be exaggerated for the purpose of explanation, and may differ from the actual dimensions.
[0014] 1 is a schematic diagram of an aromatic member according to one embodiment of the present invention. The aromatic member 1 comprises a capsule-containing substrate 2, a first liquid barrier layer 3 formed on the upper surface of the capsule-containing substrate 2, and a second liquid barrier layer 4 formed on the lower surface of the capsule-containing substrate 2.
[0015] Fig. 2 is a cross-sectional view of the aromatic member 1 of Fig. 1. The capsule-containing substrate 2 is composed of a substrate 5 having a recess, and a collapsible capsule 6 containing a liquid aromatic agent held in the recess of the substrate 5. The collapsible capsule 6 is exposed on the upper surface of the substrate 5. The first liquid barrier layer 3 is composed of an adhesive layer 7 and a non-adhesive layer 8. The adhesive layer 7 exhibits liquid barrier properties. The non-adhesive layer 8 is, for example, a felt sheet and does not exhibit liquid barrier properties. Furthermore, the second liquid barrier layer 4 is composed of an adhesive layer 9. The adhesive layer 9 exhibits liquid barrier properties.
[0016] Fig. 3 is a schematic diagram of the application of the aromatic member 1 of Fig. 1 to a mask. The aromatic member 1 is attached to the inside of the mask 10, i.e., the side that comes into contact with the nose and mouth. In this case, the aromatic member is attached to the mask 10 via the second liquid barrier layer 2 (adhesive layer 9).
[0017] Pressing the aromatic member 1 attached to the mask causes the collapsible capsules 6 to collapse. This causes the liquid aromatic to flow out of the collapsible capsules 6, and the liquid aromatic to volatilize appropriately, allowing the user to enjoy the scent. Here, the aromatic member 1 has the first liquid barrier layer 3 and the second liquid barrier layer 4, so the flowed-out liquid aromatic is retained inside the base 5. Since the liquid aromatic does not seep out to the outside through the first liquid barrier layer 3 and the second liquid barrier layer 4, it is possible to prevent the liquid aromatic that flows out when pressed from becoming sticky on the fingers. In addition, since the liquid aromatic does not seep out to the outside through the second liquid barrier layer 4, it is possible to prevent the liquid aromatic that flows out when pressed from seeping out into the mask 10. As a result, the mask can be reused, and the appearance of the adherend is not impaired.
[0018] (1) Capsule-containing substrate The capsule-containing substrate comprises a substrate and a collapsible capsule containing a liquid fragrance held within the substrate.
[0019] [Base] The base has a function of retaining the collapsible capsule and retaining the liquid fragrance that flows out of the collapsible capsule when the fragrance member is in use. In this case, the base is preferably liquid permeable.
[0020] Substrates include flexible and non-flexible substrates.
[0021] The raw material for the flexible substrate is not particularly limited, but examples thereof include wool, cat hair, camel hair, rabbit hair, silk, feathers, carbon fiber, aramid fiber, glass fiber, cellulose fiber, nylon fiber, vinylon fiber, polyester fiber, polyethylene fiber, polypropylene fiber, polyolefin fiber, rayon fiber, etc. These raw materials for the flexible substrate may be used alone or in combination of two or more kinds.
[0022] The form of the flexible substrate is not particularly limited, but examples thereof include woven fabric, nonwoven fabric, felt, and the like.
[0023] The non-flexible substrate is not particularly limited, but examples thereof include hard paper, cardboard, and porous board.
[0024] The substrate may be laminated in two or more layers. In this case, the laminated substrates may be different from each other or the same. For example, two or more layers of different flexible substrates may be laminated, two or more layers of the same flexible substrate may be laminated, or two or more layers of a flexible substrate and a non-flexible substrate may be laminated.
[0025] The shape of the substrate is not particularly limited, but may be a disk, a cube, or a rectangular parallelepiped.
[0026] The thickness of the substrate is preferably 2 mm to 12 cm, more preferably 2 to 9 mm, and even more preferably 2 to 5 mm. When the substrate is laminated, it is preferable that the laminated substrates as a whole have a thickness in the above range.
[0027] The base may have at least one recess and one through hole. By having the recess and the through hole, the collapsible capsule described later can be suitably held. In one embodiment, the base preferably has one, two, or three recesses, and more preferably has one recess from the viewpoint of manufacturing efficiency. In another embodiment, the base preferably has one, two, or three through holes, and more preferably has one through hole from the viewpoint of manufacturing efficiency. In addition, a base having a through hole is preferable from the viewpoints that the capsule can be inserted from either side of both sides, the degree of freedom of the manufacturing process can be obtained, the fragrance member can be made lighter, etc., compared with a base having a recess. In addition, two or three recesses or through holes are preferable because two or three collapsible capsules can be held and a large amount of liquid fragrance can be contained per fragrance member.
[0028] [Collapseable capsule] The collapsible capsule contains a liquid aromatic. The collapsible capsule is held by a base and disintegrates when used, causing the liquid aromatic to spill out. The user can enjoy the scent by inhaling the volatile liquid aromatic, and can obtain a relaxing effect, a refreshing effect, an invigorating feeling, and the like. In this specification, "disintegrable" means that the capsule shell can be disintegrated by external pressure to cause the liquid aromatic to spill out, preferably that the capsule shell can be disintegrated by the pressure applied by the user's finger to cause the liquid aromatic to spill out. In addition, the "liquid aromatic" means an aromatic that is 80% or more, preferably 90% or more, liquid when placed in a glass petri dish (diameter 87 mm, depth 19 mm) of 2 g and left to stand for 48 hours under conditions of a temperature of 25°C and a humidity of 40%.
[0029] In one embodiment of the present invention, the collapsible capsule comprises a capsule shell and a content, where the content comprises a liquid fragrance.
[0030] (Capsule shell) The capsule shell of the collapsible capsule is not particularly limited as long as it can encapsulate a liquid fragrance, but may contain, for example, a polysaccharide.

[0047] Among these, the liquid air freshener preferably contains a plant extract, more preferably contains at least one of limonene and caryophyllene, and further preferably contains caryophyllene. The above-mentioned liquid air fresheners may be used alone or in combination of two or more kinds.
[0048] In addition, the contents may further include at least one of a lipophilic solvent and a filler.
[0049] For example, the lipophilic solvent is not particularly limited, but is preferably vegetable oil. Examples of the vegetable oil include olive oil, linseed oil, MCT (medium chain fatty acid) oil, soybean oil, rapeseed oil (including canola oil, high erucic rapeseed oil, etc.), palm oil, palm kernel oil, sunflower oil (including high oleic sunflower oil, etc.), corn oil, cottonseed oil, rice oil, etc. These lipophilic solvents may be used alone or in combination of two or more.
[0050] (Coating layer) The collapsible capsule may further have a coating layer. By having the coating layer, the collapsible capsule can have an effect of maintaining a hardness that allows it to be easily disintegrated by fingers.
[0051] Examples of the coating agent include, but are not limited to, hydroxypropylmethylcellulose, ethylcellulose, methacrylic acid copolymer, shellac, water-soluble shellac, silicone oil, methylcellulose, carnauba wax, zein, etc. These coating agents may be used alone or in combination of two or more.
[0052] (In the form of disintegrating capsules) The shape of the collapsible capsule is not particularly limited, and may be a sphere, an ellipsoid, a cube, or a rectangular parallelepiped.
[0053] The collapsible capsule is preferably a so-called seamless capsule, which has no seams in the capsule shell. A seamless capsule is preferable because it can suppress the volatilization of the flavoring and has a spherical shape that makes it easy to break with fingers.
[0054] [Mold of capsule-containing substrate] The capsule-containing substrate has a substrate and collapsible capsules held by the substrate. In this case, the holding form of the collapsible capsules is not particularly limited. In one embodiment, the collapsible capsules are embedded in the substrate. In another embodiment, the collapsible capsules are exposed on at least one surface of the substrate. In yet another embodiment, the collapsible capsules are exposed on both surfaces of the substrate.
[0055] FIG. 4 is a schematic diagram of a capsule-containing substrate. In FIG. 4(A), the collapsible capsules 6 are embedded in the substrate 5. In FIG. 4(B), the collapsible capsules 6 are exposed on one side of the substrate 5. In this case, the substrate 5 has a recess, and the collapsible capsules 6 are held in the recess. Note that a first liquid barrier layer, which will be described later, or a second liquid barrier layer, which will be described later, may be disposed on the exposed collapsible capsules 6. In FIG. 4(C), the collapsible capsules 6 are exposed on both sides of the substrate 5. In this case, the substrate 5 has a through-hole, and the collapsible capsules 6 are held in the through-hole.
[0056] The method for holding the collapsible capsules is not particularly limited, and the collapsible capsules may be held by adhering the substrate and the substrate with an adhesive, or by utilizing the adhesive strength of the first liquid barrier layer and / or the second liquid barrier layer described below to the capsule-containing substrate, or a combination of these. Of these, from the viewpoints of production efficiency and production costs, it is preferable to hold the collapsible capsules by utilizing the adhesive strength of the first liquid barrier layer and / or the second liquid barrier layer to the capsule-containing substrate.
[0057] (2) A first liquid barrier layer and a second liquid barrier layer The first liquid barrier layer is disposed on one side of the capsule-containing substrate, and the second liquid barrier layer is disposed on the other side of the capsule-containing substrate (e.g., the side opposite to the side on which the first liquid barrier layer is disposed). The first liquid barrier layer and the second liquid barrier layer include an adhesive layer and / or a non-adhesive layer.
[0058] Here, "surface of the capsule-containing substrate" means the surface of the capsule-containing substrate when the substrate and the collapsible capsule are treated as an integrated substrate. For example, when the collapsible capsule is embedded in the substrate (e.g., FIG. 4(A)), "surface of the capsule-containing substrate" means the surface of the substrate. Also, when the collapsible capsule is exposed on both sides of the substrate (e.g., FIG. 4(C)), "surface of the capsule-containing substrate" means the substrate surface - exposed surface of the collapsible capsule - substrate surface.
[0059] In addition, the term "liquid barrier layer" refers to a layer formed on the surface of a capsule-containing substrate, which is formed to prevent liquid fragrance that flows out when a collapsible capsule is collapsed from seeping out of the substrate. In order for the layer formed on the surface of the capsule-containing substrate to become a liquid barrier layer, it is preferable that the layer exhibiting liquid barrier properties (e.g., an adhesive layer and / or a non-adhesive layer exhibiting liquid barrier properties) constituting the liquid barrier layer is formed on the surface of the capsule-containing substrate so as to encapsulate a collapsible capsule projection region. In this case, the "collapsible capsule projection region" refers to the region where the collapsible capsules are projected on the surface of the capsule-containing substrate when it is assumed that the capsule-containing substrate is projected in the direction perpendicular to the surface of the capsule-containing substrate (film thickness direction). FIG. 5 is a diagram showing a collapsible capsule projection area of a capsule-containing substrate. In a capsule-containing substrate in which a collapsible capsule 6 is embedded in a substrate 5 as shown in FIG. 5(A), the area where the collapsible capsule 6 is projected on the surface of the capsule-containing substrate when the capsule-containing substrate is projected in the film thickness direction (collapsible capsule projection area 11) is the surface of the black diagonal line. In a capsule-containing substrate in which a collapsible capsule 6 is exposed on one surface of a substrate 5 as shown in FIG. 5(B), the area where the collapsible capsule 6 is projected on the surface of the capsule-containing substrate when the capsule-containing substrate is projected in the film thickness direction (collapsible capsule projection area 11) is the surface of the white diagonal line. Furthermore, in a capsule-containing substrate in which a collapsible capsule 6 is exposed on both surfaces of a substrate 5 as shown in FIG. 5(C), the area where the collapsible capsule 6 is projected on the surface of the capsule-containing substrate when the capsule-containing substrate is projected in the film thickness direction (collapsible capsule projection area 11) is the surface of the white diagonal line and the surface of the black diagonal line. 5(C), since the exposed surface of the collapsible capsule 6 is small compared to the collapsible capsule projection area 11, not only the exposed surface of the collapsible capsule 6 but also the surface of the base 5 is included in the collapsible capsule projection area 11. A layer exhibiting liquid barrier properties is formed on the surface of the capsule-containing base so as to encapsulate such collapsible capsule projection area 11, whereby a liquid barrier layer can be formed.
[0060] (Adhesive layer) The adhesive layer is usually made of an adhesive. Since the adhesive layer has a layer structure with few gaps, it usually corresponds to a layer that exhibits liquid barrier properties, and liquid air fresheners do not seep out from the inside of the adhesive layer to the outside in principle.
[0061] The adhesive is not particularly limited, but examples thereof include epoxy resins, acrylic resins, methacrylic resins, silicone resins, urethane resins, polyester resins, rubber, cyanoacrylate, etc. These adhesives may be used alone or in combination of two or more kinds.
[0062] The adhesive layer may be formed on a part of the surface of the capsule-containing substrate, or may be formed on the entire surface. When the adhesive layer is formed on a part of the surface of the capsule-containing substrate, the surface of the capsule-containing substrate may have two or more adhesive layers. In a preferred embodiment, the adhesive layer is formed so as to encompass the collapsible capsule projected region in an area that is 1.2 to 6 times, 1.2 to 4 times, 1.2 to 2 times, 1.5 to 6 times, 1.5 to 4 times, 1.5 to 2 times, 1.8 to 6 times, 1.8 to 4 times, 1.8 to 2 times, 2 to 6 times, 2 to 4 times, or 2 to 3 times the area of the collapsible capsule projected region. In another preferred embodiment, the adhesive layer is formed on the entire surface of the capsule-containing substrate. Since the adhesive has high conformability, for example, the adhesive layer can be suitably formed even on a capsule-containing substrate having a configuration in which the collapsible capsules are exposed (a capsule-containing substrate having a convex portion).
[0063] The thickness of the adhesive layer is preferably less than 10% of the thickness of the substrate, and more preferably 2 to 5%.
[0064] The thickness of the adhesive layer is preferably 10 μm to 2 mm.
[0065] (Non-adhesive layer) The non-adhesive layer is usually adhered to the capsule-containing substrate via an adhesive layer, and has the function of imparting design and texture to the fragrance member.
[0066] The non-adhesive layer may be a non-adhesive layer that exhibits liquid barrier properties or a non-adhesive layer that does not exhibit liquid barrier properties.
[0067] The non-adhesive layer exhibiting liquid barrier properties has a dense layer structure. An example of the non-adhesive layer exhibiting liquid barrier properties is a plate-shaped member.
[0068] The plate-like member is not particularly limited, but examples thereof include wood sheets, polyoxymethylene sheets (Duracon (registered trademark) sheets, etc.), polytetrafluoroethylene (PTFE) sheets, vinyl chloride sheets, polyethylene (PE) sheets, polypropylene (PP) sheets, urethane sheets, polyethylene terephthalate (PET) sheets, polycarbonate (PC) sheets, etc. Among plate-like members, a plate-like member that cannot be folded and exhibits liquid barrier properties is particularly referred to as a rigid plate-like member. Examples of the rigid plate-like member include wood sheets, polyoxymethylene sheets, etc.
[0069] In one embodiment, the non-adhesive layer exhibiting liquid barrier properties is preferably a rigid plate-like member, and more preferably a wood sheet or a polyoxymethylene sheet.
[0070] The thickness of the plate-like member is not particularly limited, but is preferably 50 μm to 100 mm.
[0071] The non-adhesive layer that does not exhibit liquid barrier properties is not particularly limited, but examples thereof include those used for the above-mentioned substrates.
[0072] The thickness of the non-adhesive layer that does not exhibit liquid barrier properties is not particularly limited, but is preferably 0.5 to 5 mm.
[0073] The above-mentioned non-adhesive layers may be used alone or in combination of two or more kinds.
[0074] (Configuration of the first liquid barrier layer and the second liquid barrier layer) The configurations of the first liquid barrier layer and the second liquid barrier layer are not particularly limited.
[0075] In one embodiment, it is preferable that at least one of the first liquid barrier layer and the second liquid barrier layer consists of an adhesive layer, and it is more preferable that at least one of the first liquid barrier layer and the second liquid barrier layer consists of an adhesive layer.
[0076] In one embodiment, at least one of the first liquid barrier layer and the second liquid barrier layer is preferably composed of an adhesive layer and a non-adhesive layer. In a preferred embodiment, one of the first liquid barrier layer and the second liquid barrier layer is composed of an adhesive layer and a non-adhesive layer. In another preferred embodiment, both the first liquid barrier layer and the second liquid barrier layer are composed of an adhesive layer and a non-adhesive layer.
[0077] When at least one of the first liquid barrier layer and the second liquid barrier layer is an adhesive layer, in one embodiment, it is preferred that the adhesive layer exhibits liquid barrier properties. In another embodiment, it is preferred that the non-adhesive layer exhibits liquid barrier properties. In yet another embodiment, it is preferred that the adhesive layer and the non-adhesive layer exhibit liquid barrier properties.
[0078] When the non-adhesive layer exhibits liquid barrier properties, the non-adhesive layer is a non-adhesive layer exhibiting liquid barrier properties, and is preferably made of a rigid plate-like member, and more preferably made of a wood sheet or a polyoxymethylene sheet.
[0079] FIG. 6 is a schematic diagram showing the configurations of the first liquid barrier layer and the second liquid barrier layer.
[0080] In Figure 6(A), a first liquid barrier layer 3 is formed on a part of the upper surface of a capsule-containing substrate 2 consisting of a substrate 5 having a through hole and a collapsible capsule 6 held in the through hole of the substrate 5, and a second liquid barrier layer 4 is formed on the entire lower surface of the capsule-containing substrate 2. The first liquid barrier layer 3 is composed of an adhesive layer 7 and a non-adhesive layer (a non-adhesive layer that does not exhibit liquid barrier properties, for example, a wool felt sheet) 8. In this case, the adhesive layer 7 exhibits liquid barrier properties and is formed on a part of the upper surface of the capsule-containing substrate 2 so as to encapsulate the collapsible capsule projected area. On the other hand, the second liquid barrier layer 4 is made of an adhesive layer 9. In this case, the adhesive layer 9 exhibits liquid barrier properties and is formed on the entire lower surface of the capsule-containing substrate 2 so as to encapsulate the collapsible capsule projected area. In Fig. 6(A), the first liquid barrier layer 3 is composed of an adhesive layer 7 and a non-adhesive layer 8, and the second liquid barrier layer 4 is composed of an adhesive layer 9. Here, in the first liquid barrier layer 3, the adhesive layer 7 exhibits liquid barrier properties, and in the second liquid barrier layer 4, the adhesive layer 9 exhibits liquid barrier properties. Since the second liquid barrier layer 4 is composed of the adhesive layer 9, a fragrance member having such a configuration is usually used by being attached to an adherend. In Fig. 6(A), the adhesive layers (adhesive layers 7 and 9) on both the upper and lower surfaces of the capsule-containing substrate 2 exhibit liquid barrier properties. The adhesive layer can prevent the liquid aromatic from seeping out regardless of its thickness, allowing the aromatic member to be made thin and compact. In addition, when the aromatic member in Fig. 6(A) is pressed with a finger to break the collapsible capsule, for example, the force of the finger is directly applied to the collapsible capsule, so the collapsible capsule can be easily broken.
[0081] In Figure 6(B), similar to Figure 6(A), a first liquid barrier layer 3 is formed on a part of the upper surface of a capsule-containing substrate 2 consisting of a substrate 5 having a through hole and a collapsible capsule 6 held in the through hole of the substrate 5, and a second liquid barrier layer 4 is formed on the entire lower surface of the capsule-containing substrate 2. 6(A), the first liquid barrier layer 3 is composed of an adhesive layer 7 and a non-adhesive layer (a non-adhesive layer that does not exhibit liquid barrier properties, such as a wool felt sheet) 8. In this case, the adhesive layer 7 exhibits liquid barrier properties and is formed on a part of the upper surface of the capsule-containing substrate 2 so as to encapsulate the collapsible capsule projected area. On the other hand, the second liquid barrier layer 4 is composed of an adhesive layer 9 and a non-adhesive layer (a non-adhesive layer exhibiting liquid barrier properties, for example, a wooden sheet that is a plate-like member) 12. In this case, the non-adhesive layer 12 exhibits liquid barrier properties and is formed on the lower surface of the capsule-containing substrate 2 so as to encapsulate the collapsible capsule projected area. In Fig. 6(B), the first liquid barrier layer 3 is composed of an adhesive layer 7 and a non-adhesive layer 8, and the second liquid barrier layer 4 is composed of an adhesive layer 9 and a non-adhesive layer 12. Here, in the first liquid barrier layer 3, the adhesive layer 7 exhibits liquid barrier properties, and in the second liquid barrier layer 4, the adhesive layer 9 and the non-adhesive layer 12 exhibit liquid barrier properties. A fragrance member having such a configuration is usually used for applications such as key holders, pendants, earrings, bracelets, and sachets (fragrant bags), since neither the first liquid barrier layer 3 nor the second liquid barrier layer 4 has an adhesive layer as its outermost layer. In Fig. 6(B), the fragrance material has a strong structure because it includes a plate-shaped member as the non-adhesive layer 12. In addition, the plate-shaped member used as the non-adhesive layer 12 can be removed and reused. In addition, in Fig. 6(B), the adhesive layer is not exposed, so it can be combined with other members.
[0082] In Figure 6(C), similar to Figure 6(A), a first liquid barrier layer 3 is formed on a part of the upper surface of a capsule-containing substrate 2 consisting of a substrate 5 having a through hole and a collapsible capsule 6 held in the through hole of the substrate 5, and a second liquid barrier layer 4 is formed on the entire lower surface of the capsule-containing substrate 2. 6(A), the first liquid barrier layer 3 is composed of an adhesive layer 7 and a non-adhesive layer (a non-adhesive layer that does not exhibit liquid barrier properties, such as a wool felt sheet) 8. In this case, the adhesive layer 7 exhibits liquid barrier properties and is formed on a part of the upper surface of the capsule-containing substrate 2 so as to encapsulate the collapsible capsule projected area. On the other hand, the second liquid barrier layer 4 is composed of an adhesive layer 9 and a non-adhesive layer (a non-adhesive layer that does not exhibit liquid barrier properties, for example, a wool felt sheet) 12. In this case, the adhesive layer 9 exhibits liquid barrier properties and is formed on the entire lower surface of the capsule-containing substrate 2 so as to encapsulate the collapsible capsule projected area. In Fig. 6(C), the first liquid barrier layer 3 is composed of an adhesive layer 7 and a non-adhesive layer 8, and the second liquid barrier layer 4 is composed of an adhesive layer 9 and a non-adhesive layer 12. Here, in the first liquid barrier layer 3, the adhesive layer 7 exhibits liquid barrier properties, and in the second liquid barrier layer 4, the adhesive layer 9 exhibits liquid barrier properties. In a fragrance member having such a configuration, since neither the first liquid barrier layer 3 nor the second liquid barrier layer 4 has an adhesive layer as its outermost layer, they are usually used for applications such as key holders, pendants, earrings, bracelets, sachets (fragrant bags), etc. In Fig. 6(C), the adhesive layers (adhesive layers 7 and 9) on both the upper and lower surfaces of the capsule-containing substrate 2 exhibit liquid barrier properties. The adhesive layer can prevent the liquid fragrance from seeping out regardless of its thickness, allowing the fragrance material to be made thin and compact. In addition, since the adhesive layer is not exposed in Fig. 6(C), it can be combined with other materials.
[0083] In Figure 6(D), a first liquid barrier layer 3 is formed on a part of the upper surface of a capsule-containing substrate 2 consisting of a substrate 5 having a recess and a collapsible capsule 6 held in the recess of the substrate 5, and a second liquid barrier layer 4 is formed on the entire lower surface of the capsule-containing substrate 2. 6(A), the first liquid barrier layer 3 is composed of an adhesive layer 7 and a non-adhesive layer (a non-adhesive layer that does not exhibit liquid barrier properties, such as a wool felt sheet) 8. In this case, the adhesive layer 7 exhibits liquid barrier properties and is formed on a part of the upper surface of the capsule-containing substrate 2 so as to encapsulate the collapsible capsule projected area. On the other hand, the second liquid barrier layer 4 is made of an adhesive layer 9. In this case, the adhesive layer 9 exhibits liquid barrier properties and is formed on the entire lower surface of the capsule-containing substrate 2 so as to encapsulate the collapsible capsule projected area. In Fig. 6(D), the first liquid barrier layer 3 is composed of an adhesive layer 7 and a non-adhesive layer 8, and the second liquid barrier layer 4 is composed of an adhesive layer 9. Here, in the first liquid barrier layer 3, the adhesive layer 7 exhibits liquid barrier properties, and in the second liquid barrier layer 4, the adhesive layer 9 exhibits liquid barrier properties. Since the second liquid barrier layer 4 is composed of the adhesive layer 9, a fragrance member having such a configuration is usually used by being attached to an adherend. In Fig. 6(D), the adhesive layers (adhesive layers 7 and 9) on both the upper and lower surfaces of the capsule-containing substrate 2 exhibit liquid barrier properties. The adhesive layer can prevent the liquid fragrance from seeping out regardless of its thickness, allowing the fragrance member to be made thin and compact. In addition, in order for the liquid fragrance flowing out of the collapsible capsules 6 to seep out onto the adherend, it must pass not only through the adhesive layer 9 but also through the substrate 5 (e.g., a felt sheet), which can further enhance the effect of preventing seepage into the adherend.
[0084] 6(A) to (D) can be modified as appropriate. For example, the capsule-containing substrate 2 used in Fig. 6(A) to (C) may be a capsule-containing substrate made up of a substrate and a collapsible capsule embedded in the substrate, or a capsule-containing substrate made up of a substrate having a recess and a collapsible capsule containing a liquid fragrance held in the recess of the substrate. As the non-adhesive layer 8 constituting the first liquid barrier layer 3 in Figs. 6(A) to 6(D), a non-adhesive layer exhibiting liquid barrier properties, for example a wood sheet, may be used. Furthermore, the first liquid barrier layer 3 may be formed on the entire upper surface of the capsule-containing substrate 2, rather than on a portion of it. The second liquid barrier layer 4 may be formed on the entire lower surface of the capsule-containing substrate 2, rather than on a portion of it, so as to include at least the collapsible capsule projection region. In one embodiment, the first liquid barrier layer and / or the second liquid barrier layer are preferably formed on the entire surface of the face of the capsule-containing substrate. In another embodiment, the first liquid barrier layer and / or the second liquid barrier layer is preferably formed to cover 10% or more, 20% or more, 30% or more, 40% or more, 50% or more, 60% or more, 70% or more, or 80% or more of the total surface of the face of the capsule-containing substrate so as to encapsulate at least the collapsible capsule projection region. Also, the first liquid barrier layer and / or the second liquid barrier layer is preferably formed to cover 90% or less, 80% or less, 70% or less, 60% or less, or 50% or less of the total surface of the face of the capsule-containing substrate so as to encapsulate at least the collapsible capsule projection region. Specifically, the first liquid barrier layer and / or the second liquid barrier layer is preferably formed to cover 30-90%, 40-90%, 50-90%, 60-90%, 70-90%, 30-80%, 40-80%, 50-80%, 60-80%, 70-80%, 30-70%, 40-70%, 50-70%, or 60-70% of the entire surface of the face of the capsule-containing substrate so as to encapsulate at least the collapsible capsule projection region. By forming the first liquid barrier layer and / or the second liquid barrier layer on a portion of the entire surface of the face of the capsule-containing substrate so as to encapsulate the collapsible capsule projection region, the aromatic member can promote the volatilization of the aromatic liquid.
[0085] (3) Mount The aromatic member may have a mount. For example, when the first liquid barrier layer and / or the second liquid barrier layer is an adhesive layer, the mount has a function of preventing contamination of the adhesive layer and a function of improving handling until the aromatic member is attached to an adherend. When in use, the aromatic member is peeled off from the mount and adhered to an adherend.
[0086] As the mount, in addition to cardboard, a laminate in which a fluorine-based resin layer is formed on a resin substrate, etc. can be used.
[0087] 2. Uses of aromatic materials In one embodiment of the present invention, the fragrance member can be used for various purposes. For example, the fragrance member is preferably attached to a mask, skin, clothing, shoes, or bag. When at least one of the first liquid barrier layer and the second liquid barrier layer of the fragrance member is made of an adhesive layer, preferably when either one of the first liquid barrier layer and the second liquid barrier layer of the fragrance member is made of an adhesive layer, the fragrance member can be attached to a mask, skin, clothing, shoes, or bag via the adhesive layer.
[0088] The aromatic member is preferably used as a key holder, pendant, earrings, bracelet, sachet (sachet), etc. When the first liquid barrier layer and the second liquid barrier layer of the aromatic member are both made of an adhesive layer and a non-adhesive layer, the aromatic member does not have an adhesive layer as the outermost layer, and therefore does not stick to the skin when used for the above-mentioned purposes, and can be used comfortably. For example, when the non-adhesive layer of either the first liquid barrier layer or the second liquid barrier layer is a wood sheet, a pendant can be made by drilling a hole in the wood sheet and passing a string or chain for the pendant through the hole. EXAMPLES
[0089] The present invention will be specifically described below with reference to examples, but the present invention is not limited to these.
[0090] [Example 1] A fragrance member was manufactured in which a first liquid barrier layer was formed on a portion of the upper surface of a capsule-containing substrate, which was composed of a substrate having a through hole and a collapsible capsule held in the through hole of the substrate, and a second liquid barrier layer was formed on the entire lower surface of the capsule-containing substrate (see FIG. 6(B)). In this case, the first liquid barrier layer was composed of an adhesive layer and a non-adhesive layer, and the adhesive layer exhibited liquid barrier properties. The second liquid barrier layer was composed of an adhesive layer and a non-adhesive layer, and the adhesive layer and the non-adhesive layer exhibited liquid barrier properties.
[0091] FIG. 7 is a schematic diagram showing the manufacturing process of the scented member of Example 1. An adhesive layer (commercially available felt adhesive (mainly vinyl acetate resin)) 9 and a backing paper 13 were formed in this order over the entire bottom surface of the base (felt base) 5 (Fig. 7(A)). Next, a through hole was punched out in the center of the base 5 with a diameter that matched the collapsible capsule (Fig. 7(B)). An adhesive layer (commercially available felt adhesive (mainly vinyl acetate resin)) 7 was formed on part of the top surface of the base 5 (Fig. 7(C)). Next, a collapsible capsule 6 containing a mixture of orange sweet essential oil and vegetable oil (medium-chain fatty acid (MCT)), which is a liquid fragrance, was placed inside the base 5 from the bottom toward the adhesive layer 7 (Fig. 7(D)). A non-adhesive layer (felt sheet) 8 was formed on the adhesive layer 7, and then the backing paper 13 was removed (Figure 7(E)). After that, a non-adhesive layer (wood sheet) 12 having liquid barrier properties was formed on the underside of the capsule-containing substrate to cover the through holes, thereby producing the aromatic member (Figure 7(F)).
[0092] [Example 2] The aromatic member was manufactured in the same manner as in Example 1, except that in addition to the central portion of the base 5, three through holes were punched out in a row on the same base, and a collapsible capsule 6 was placed in each of the three through holes.
[0093] [Example 3] A fragrance member was manufactured in which a first liquid barrier layer was formed on a portion of the upper surface of a capsule-containing substrate, which was composed of a substrate having a through hole and a collapsible capsule held in the through hole of the substrate, and a second liquid barrier layer was formed on the entire lower surface of the capsule-containing substrate (see FIG. 6(A)). In this case, the first liquid barrier layer was composed of an adhesive layer and a non-adhesive layer, and the adhesive layer exhibited liquid barrier properties. The second liquid barrier layer was composed of an adhesive layer, and the adhesive layer exhibited liquid barrier properties.
[0094] FIG. 8 is a schematic diagram showing the manufacturing process of the scented member of Example 3. A through hole was punched out in the center of the base (polyester nonwoven base) 5 (Fig. 8(A)). Next, an adhesive layer 9 was formed over the entire bottom surface of the base 5 (Fig. 8(B)). Next, a collapsible capsule 6 containing a liquid fragrance mixture of orange sweet essential oil and vegetable oil was placed inside the base 5 from above the base 5 toward the adhesive layer 9 (Fig. 8(C)). An adhesive layer 7 having liquid barrier properties and a non-adhesive layer (polyester nonwoven base) 8 were formed to cover the through hole on part of the top surface of the capsule-containing base, thereby producing a fragrance member (Fig. 8(D)).
[0095] [Example 4] A fragrance member was manufactured in which a first liquid barrier layer was formed on the upper surface of a capsule-containing substrate, which was composed of a substrate having a recess and a collapsible capsule held in the recess of the substrate, and a second liquid barrier layer was formed on the entire lower surface of the capsule-containing substrate. In this case, the first liquid barrier layer was composed of an adhesive layer and a non-adhesive layer, and the non-adhesive layer exhibited liquid barrier properties. In addition, the second liquid barrier layer was composed of an adhesive layer, and the adhesive layer exhibited liquid barrier properties.
[0096] FIG. 9 is a schematic diagram showing the manufacturing process of the scented member of Example 4. An adhesive layer 7 and a backing paper 13 were formed in this order on the upper surface of a base (felt base) 5 (Fig. 9(A)). Next, a recess was formed in the center of the base 5 using Ponte with a diameter that matched the diameter of the collapsible capsule (Fig. 9(B)). Next, a collapsible capsule 6 containing a liquid fragrance mixture of orange sweet essential oil and vegetable oil was placed inside the base 5 from the top toward the recess (Fig. 9(C)). After removing the backing paper 13 (Fig. 9(D)), a non-adhesive layer (wood sheet) 8 having liquid barrier properties was formed on the upper surface of the capsule-containing base so as to cover the recess, and an adhesive layer 9 was formed on the entire lower surface of the capsule-containing base to produce a fragrance member (Fig. 9(E)).
[0097] [Example 5] A fragrance member was manufactured in which a first liquid barrier layer was formed on a portion of the upper surface of a capsule-containing substrate, which was composed of a substrate having a through hole and a collapsible capsule held in the through hole of the substrate, and a second liquid barrier layer was formed on the entire lower surface of the capsule-containing substrate (see FIG. 6(C)). In this case, the first liquid barrier layer was composed of an adhesive layer and a non-adhesive layer, and the adhesive layer exhibited liquid barrier properties. The second liquid barrier layer was composed of an adhesive layer and a non-adhesive layer, and the adhesive layer exhibited liquid barrier properties.
[0098] The fragrance member of Example 5 was produced by forming a non-adhesive layer 12 on the adhesive layer 9 of the fragrance member produced in Example 3 (see FIG. 6(A)).
[0099] [Comparative Example 1] A fragrance member was manufactured in which a first liquid barrier layer was formed on the entire upper surface of a capsule-containing substrate consisting of a substrate having through holes and collapsible capsules held in the through holes of the substrate, and an adhesive layer was formed on a part of the lower surface of the capsule-containing substrate 2. In this case, the adhesive layer was not formed on the through hole portion of the lower surface of the capsule-containing substrate 2.
[0100] FIG. 10 is a schematic diagram showing the manufacturing process of the fragrance member of Comparative Example 1. A through hole was punched out at the center of the base (polyester nonwoven base) 5 (FIG. 10(A)). Next, an adhesive layer 9 was formed on the bottom surface of the base 5 except for the through hole, and a backing 13 was formed on the adhesive layer. Therefore, the adhesive layer 9 was not formed in the through hole area on the bottom surface of the base 5 (FIG. 10(B)). A collapsible capsule 6 containing a liquid fragrance mixture of orange sweet essential oil and vegetable oil was placed inside the base 5 from the top of the base 5 toward the backing 13 (FIG. 10(C)). An adhesive layer 7 having liquid barrier properties was formed on the top surface of the capsule-containing base so as to cover the through hole (FIG. 10(D)), and then a non-adhesive layer (polyester nonwoven base) 8 was formed (FIG. 10(E)). Finally, the backing 13 was removed to produce a fragrance member (FIG. 10(F)).
[0101] [Bleeding evaluation] Using the scented members of Examples 1 to 5 and Comparative Example 1, an exudation evaluation was carried out.
[0102] Specifically, the fragrant members of Examples 1, 2 and 5 were placed on filter paper with the non-adhesive layer 12 as the contact surface, or the fragrant members of Examples 3-4 and Comparative Example 1 were attached to the filter paper via the adhesive layer 9, and then the surface of the fragrant member was pressed with a finger from the non-adhesive layer 8 side to crush the disintegrable capsules 6. After 3 minutes, the filter paper was turned over to check for seepage and evaluate whether the capsule contents had seeped into the filter paper.
[0103] As a result, there was no leakage of the capsule contents in Examples 1 to 6. On the other hand, there was leakage of the capsule contents in Comparative Example 1. [Explanation of symbols]
