The holders 8 are set on both sides of the base of the nose when in use, preferably on pressure points called nasal passages. The expansion part 9 located in the center in the width direction of the nasal passage improving tool 1 is a part that is arranged to straddle the left and right sides of the nose during use to widen the nasal cavity. The shape of each part of the nasal passage improving tool 1 will be described in detail below.

The length in the width direction from the vertical center line O shown in FIG. 4 to the holding portion 8 (the distance from the vertical center line O to the boundary P3-P4 between the holding portion 8 and the connecting portion 10 described later) L2 is particularly limited. However, it is preferably 24 mm or more and 30 mm or less, more preferably 26.5 mm or more and 30 mm or less. This allows the holders 8 to be appropriately set on the nasal passages on both sides of the base of the nose during use for many users with different nose shapes.

The extension part The extension part 9 has a horizontally long shape when viewed from the front, and has a flat shape whose thickness is extremely small compared to the vertical width and the horizontal width when viewed from the side or plan view. When viewed from the front, the extended portion 9 includes an upper edge 90 and a lower edge 91 extending in the width direction, left and right upper edges 92 connected to both ends of the upper edge 90 in the width direction, and left and right edges connecting to both ends of the lower edge 91 in the width direction. and a lower edge 93 of . The extended portion 9 has a symmetrical shape with respect to a vertical center line O extending parallel to the vertical width direction at the center position in the horizontal width direction shown in FIG. 4 .

A lower edge 91 of the extension 9 is parallel to the upper edge 90 . A lower edge 91 of the extended portion 9 is recessed in a substantially trapezoidal shape at the center in the lateral width direction, has an inclined portion, and is generally parallel to the upper edge 90 . In the expansion part 9, the downwardly protruding parts 94 on both sides of the substantially trapezoidal concave part are arranged in a part of the nostril during use, so that the effect of expanding the nasal cavity by the expansion part 9 can be improved. . It should be noted that the lower edge 91 of the extended portion 9 does not necessarily have to be recessed at the center in the widthwise direction.

The upper edge 92 of the extension portion 9 is inclined downward toward the outside in the width direction (the side opposite to the center), and connects the upper edge 90 of the extension portion 9 and the upper edge 100 of the connecting portion 10. there is Since the upper edge 92 is slanted obliquely downward, the extension part 9 can be brought into close contact with the nose without covering the bridge of the nose, and floating of the extension part 9 can be suppressed. A lower edge 93 of the extended portion 9 is inclined upward toward the outside in the width direction (the side opposite to the center), and connects the lower edge 91 of the extended portion 9 and the lower edge 101 of the connecting portion 10 . I'm in.

In FIG. 4, P1 is the connection point between the upper edge 92 of the linear extension portion 9 and the upper edge 100 of the curved connection portion 10, and P2 is the connection point between the lower edge 93 of the linear extension portion 9 and the upper edge 100 of the curved connection portion 10. It is a connection point with the lower edge 101 of the curved connecting portion 10 . A line connecting P1 and P2 along the longitudinal width direction is the boundary between the extension portion 9 and the connecting portion 10 .

Although the vertical width of the extended portion 9 is not particularly limited, it is preferably at least 11 mm or more, that is, the vertical width D2 of the recessed portion of the lower edge 91 at the center in the horizontal direction shown in FIG. 4 is 11 mm or more, More preferably, it is 13 mm or more. As a result, the nasal cavity can be effectively expanded by the expanding portion 9 during use. On the other hand, the vertical width of the extended portion 9 is not particularly limited, but is preferably 21 mm or less at most. is 21 mm or less, more preferably 18 mm or less, still more preferably 16 mm or less. Thereby, the nasal cavity can be efficiently widened by the extension part 9 without the extension part 9 protruding from the nose.

The width from the longitudinal center line O of the extension 9 shown in FIG. Although the length L3 is not particularly limited, it is preferably 20 mm or more and 24 mm or less, more preferably 22 mm or more and 23.5 mm or less. Thereby, the extension part 9 can be brought into close contact with the nose during use, and the extension part 9 can be prevented from floating from the nose.

The inclination angle θ1 of the upper edge 92 of the extended portion 9 shown in FIG. 4 with respect to the upper edge 90 is not particularly limited, but is preferably 51° or more and 90° or less, and more preferably 51° or more and 70° or less. is. The upper edge 92 of the extension 9 is inclined with respect to the upper edge 93, so that the upper edge 92 of the extension 9 is positioned along the base of the nose when in use, and the extension 9 conforms to the shape of the nose. can be installed by By setting the inclination angle θ1 of the upper edge 92 to the upper edge 90 within the above range, the above effects can be satisfactorily achieved.

The inclination angle θ2 of the lower edge 93 of the extended portion 9 shown in FIG. ° or less. Since the lower edge 93 of the extended portion 9 is inclined with respect to the lower edge 91, the lower edge 93 of the extended portion 9 is arranged to avoid the nostrils during use, and the extended portion 9 conforms to the shape of the nose. can be installed by Since the inclination angle θ2 of the lower edge 91 of the lower edge 93 is within the above range, the above effects can be satisfactorily achieved.

Connecting Portion The connecting portion 10 has a horizontally elongated shape with a horizontal width (indicated by L2-L3 in FIG. 4) longer than the vertical width D4 shown in FIG. 4 when viewed from the front. The connecting portion 10 has a flat shape whose thickness is extremely small compared to its vertical width and horizontal width when viewed from the side or from the top.

Although the vertical width D4 of the connecting portion 10 is not particularly limited, it is preferably significantly smaller than the vertical width D1 of the holding portion 8 and the vertical widths D2 and D3 of the extension portions 9 as in the present embodiment. Therefore, the connecting portion 10 can be easily bent in the front-rear direction when viewed from the front. As a result, the nasal passage improving tool 1 can easily bend the holding portion 8 with respect to the expanding portion 9 at the connecting portion 10 which is the boundary between the holding portion 8 and the expanding portion 9, and expands the holding portion 8 at the base of the nose during use. By firmly folding the part 9, the holding part 8 can be brought into close contact with the skin on both sides of the base of the nose. In addition, since the holding part 8 is in close contact with the skin and the position where the holding part 8 is set is fixed, it is possible to suppress the expansion part 9 from being bent more than a certain amount during use, and the bending of the expansion part 9 can be prevented. can be suppressed.

In addition, since the vertical width D1 of the holding portion 8 is large, the holding portion 8 can be firmly attached to both sides of the base of the nose to prevent displacement. In addition, since the vertical widths D2 and D3 of the extended portion 9 are large, the contact area of the extended portion 9 with the nose can be increased, and the extended portion 9 can greatly expand the nasal cavity.

The connecting portion 10 has an upper edge 100 that connects the upper edge 92 of the extension portion 9 and the outer peripheral edge 80 of the holding portion 8 , and a lower edge 101 that connects the lower edge 93 of the extension portion 9 and the outer peripheral edge 80 of the holding portion 8 . and The upper edge 100 and the lower edge 101 of the connecting portion 10 are parallel to each other, and the vertical width D4 is constant over the entire horizontal width.

Although the connecting portion 10 is not particularly limited, it preferably has a shape that is convex and curved in the longitudinal and width directions when viewed from the front, as in the present embodiment. Therefore, the upper edge 100 and the lower edge 101 of the connecting portion 10 also exhibit a curvilinear shape that protrudes in the longitudinal width direction. The connecting portion 10 of the present embodiment is curved upward in the longitudinal width direction (toward the upper edge 90 of the extended portion 9). Since the connecting part 10 is convexly curved in the longitudinal width direction, the connecting part 10 can be easily deformed in the direction in which the width is widened or narrowed during use. As a result, the positions where the holding parts 8 are set on both sides of the base of the nose can be adjusted left and right, so even if many users with different nose shapes use the nasal passage improving tool 1, each user can By appropriately adjusting the set position of the holding part 8, the holding part 8 can be set on the nasal passage. Note that the connecting portion 10 may be convex and curved toward the lower side in the longitudinal width direction (the side of the lower edge 91 of the extended portion 9). Further, the connecting portion 10 may be curved to form a convex shape, instead of forming a convex shape toward the upper side or the lower side in the longitudinal width direction and curving smoothly.

In FIG. 4, P3 is a connection point between the upper edge 100 of the curved connecting portion 10 and the outer peripheral edge 80 of the arc-shaped holding portion 8, and P4 is a connecting point between the lower edge 101 of the curved connecting portion 10 and the circular It is a connection point with the outer peripheral edge 80 of the arc-shaped holding part 8 . A line connecting P3 and P4 along the longitudinal width direction is the boundary between the holding portion 8 and the connecting portion 10 .

Although the vertical width D4 of the connecting portion 10 is not particularly limited, it is preferably 8 mm or less, more preferably 6 mm or less. As a result, the above-described bending and deformation of the connecting portion 10 can be easily performed. In addition, the smaller the vertical width D4 of the connecting portion 10, the easier the bending and deformation of the connecting portion 10 described above. The strength of the connecting portion 10 can be secured while the vertical width D4 is small, and damage such as tearing due to bending or deformation of the connecting portion 10 can be suppressed.

Although the connection portion 10 is not particularly limited, preferably, the connection point P2 with the extension portion 9 on the lower side in the longitudinal width direction shown in FIG. It is located within the range of 30% or more and 50% or less of the vertical width. The lower end of the extended portion 9 is a portion of the lower edge 91 of the extended portion 9 that is located on the lowermost side in the longitudinal width direction. The vertical width of the extended portion 9 is the maximum vertical width D3 of the extended portion 9 shown in FIG. That is, the connecting portion 10 is connected to the extension portion 9 from the lower end of the extension portion 9 shown in FIG. The vertical width D5 from the points P1 and P2 to the lower connection point P2 in the vertical width direction is preferably 30% or more and 50% or less of the maximum vertical width D3 of the extension portion 9, more preferably the extension portion. It is 37.5% or more and 43.75% or less of the maximum vertical width D3 of 9. Thereby, the extension part 9 can be brought into close contact with the nose during use, and the extension part 9 can be prevented from floating from the nose.

Constituent members of nasal passage improving device As shown in FIGS. The base material 2 is arranged so as to straddle the nose from side to side during use. The exothermic material 3 is held at both ends (hereinafter simply referred to as "both ends") of the substrate 2 in the width direction, and warms the nose and the vicinity of the nose during use. The adhesive layer 4 is formed on the back surface of the base material 2 which is in contact with the nose, and adheres the base material 2 to the nose and the skin in the vicinity of the nose. The release sheet 5 is attached to the back surface of the base material 2 so as to cover the adhesive layer 4, and the adhesive layer 4 is removed before the nose passage improving device 1 is worn on the nose (hereinafter referred to as "when not in use"). Protect. Hereinafter, each component of the nasal passage improving tool 1 will be described in detail.

Base material The base material 2 has a front view shape of the nasal passage improver 1 and has a horizontally long shape with a horizontal width L0 longer than the vertical width D0 shown in FIG. In the base material 2, the central portion in the width direction forming the expanded portion 9 (hereinafter simply referred to as the "central portion") straddles the nose on the left and right, and the both ends forming the pair of holding portions 8 described above extend over the nose. It is formed in a length that allows it to be set on both sides of the base (preferably on the points called nasal passages).

In addition, the base material 2 has a flat shape in which the thickness is extremely small compared to the vertical width and the horizontal width in a side view or a plan view, except for a part of both ends. The thickness of the flat portion of the substrate 2 is not particularly limited, but is preferably 0.5 mm or more and 2 mm or less. A part of both ends of the base material 2 is a part forming the protruding part 82 for housing the heat generating material 3 described above, and the front side protrudes higher than the back side.

The base material 2 has elasticity over the entire length in the width direction. That is, the base material 2 can be bent in the front-rear direction by applying an external force at any position in the width direction, and when the external force is removed, the base material 2 returns to its original shape (original shape). It has a high tendency to return. When the base material 2 is placed across the nose in use, the central portion (expansion portion 9) is bent in a chevron shape along the shape of the nose. Since the base material 2 has elasticity, the nasal cavity can be widened by its elastic restoring force.

In addition, the base material 2 has flexibility over the entire length in the width direction. That is, the base material 2 can be easily bent and bent in the front-rear direction when viewed from the front by applying an external force at any position in the width direction. It has the property of being hard to break. The base material 2 is arranged so as to straddle the nose from side to side during use, so that the central portion is bent in a chevron shape. If the base material 2 snaps when it is folded, the base material 2 loses its elasticity and cannot be restored to its original shape after being bent. Since the base material 2 has flexibility and bends flexibly when bent, the base material 2 is prevented from snapping off.

The base material 2 is composed of a back side member 7 on the side that contacts the nose and a front side member 6 laminated on the back side member 7 . The front side member 6 and the back side member 7 are presenting a sheet shape. A portion of both ends of the front member 6 in the lateral width direction is raised higher than the other portions to form the protrusions 82 described above. The front side member 6 is joined to the back side member 7 except for the protrusion 82 , and the heat generating material 3 is stored between the front side member 6 and the back side member 7 at the protrusion 82 . The method of joining the front side member 6 and the back side member 7 is not particularly limited, and for example, various known methods such as adhesion with an adhesive or pressure sensitive adhesive, heat welding, ultrasonic welding, etc. can be used. .

For the front side member 6 and the back side member 7, for example, a woven fabric, a nonwoven fabric, a paper material, or the like can be used. Raw material fibers for woven or non-woven fabrics include natural fibers such as cotton, hemp, silk and pulp; semi-synthetic fibers such as rayon and acetate; nylon, vinylon, polyester, acrylic, polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, Synthetic fibers such as polybutylene terephthalate; mixed fibers of these fibers and the like can be exemplified. Considering the strength and durability against heat generation of the heat generating material 3, a laminate obtained by laminating a resin film on a woven fabric or a nonwoven fabric may be used. Thermoplastic resins are preferred as raw material resins for resin films, and thermoplastic resins include polyethylene, polypropylene, polyester, polyamide, polyurethane, polystyrene, polyvinyl alcohol, polyvinyl chloride, polyvinylidene chloride, polycarbonate, and ethylene-vinyl acetate. A polymer etc. can be illustrated. Examples of the paper material include liner paper and other thick paper.

In this embodiment, the heat generating material 3 generates heat when it comes into contact with air, so the front side member 6 has air permeability. The air permeability of the front side member 6 is not particularly limited, but the heat generating material 3 has the desired heat generating characteristics (maximum heat generation temperature, duration of heat generation temperature exceeding a predetermined temperature, until the heat generation temperature exceeds a predetermined temperature It is preferable that the air permeability is set such that an appropriate amount of air (oxygen) can be brought into contact with the heat generating material 3 so as to achieve a rise time required for the heat generating material 3 .

Further, in this embodiment, the front member 6 has elasticity over the entire length in the width direction, so that the base material 2 has elasticity over the length in the width direction. For example, rigid nonwoven fabric can be used for the breathable and elastic front member 6 . A rigid nonwoven fabric does not deform and retains its shape when no external force is applied. Examples of rigid nonwoven fabrics include Smash (registered trademark) manufactured by Asahi Kasei Corporation, urethane foam, and the like. Smash (registered trademark) is a non-woven fabric obtained by using polyethylene terephthalate as a raw material fiber and by a spunbond method, and can be thermoformed. When the front side member 6 is a thermoformed nonwoven fabric, the protrusions 82 for storing the heat generating material 3 can be formed on the front side member 6, and the protrusions 82 can have shape retention due to rigidity. can.

In this embodiment, since the front member 6 is breathable, the back member 7 may be breathable or non-breathable. Further, like the front side member 6, the back side member 7 preferably has elasticity over the entire length in the width direction. Further, it is preferable that the back side member 7 has flexibility over the entire length in the width direction. Since the back side member 7 has flexibility, it is possible to suppress the front side member 6 from snapping when the front side member 6 is bent, and prevent the front side member 6 from losing its elasticity. For the flexible back side member 7, for example, cardboard such as liner paper, silicon, artificial leather, or the like can be used.

Exothermic Material The exothermic material 3 is a material capable of generating heat. In this embodiment, the exothermic material 3 causes an oxidation reaction when it comes into contact with oxygen in the air, and generates heat along with the oxidation reaction. This type of heat generating material 3 includes an oxidizable metal (for example, one or more powders or fibers selected from iron, aluminum, zinc, manganese, magnesium, and calcium), activated carbon, carbon black, and a water retention agent. (e.g., wood flour, vermiculite, diatomaceous earth, perlite, silica gel, alumina, water-absorbing resin, etc.), metal salt (e.g., common salt, etc.), and water in appropriate amounts. can. The oxidizable metal is preferably iron powder, such as reduced iron powder or atomized iron powder, from the viewpoints of handling, safety, production cost, storage stability and stability. As the exothermic composition described above, a known composition that has been conventionally used in disposable body warmers can be used.

The exothermic material 3 is not particularly limited, but in this embodiment, it is a tablet-molded body produced by tablet-molding the exothermic composition described above as a raw material. Tableting is to press raw materials into a tablet shape with a tableting machine. The tablet compact has a size that can be stored in the storage space in the projecting portion 82 of the base material 2 and a shape that matches the storage space. When the exothermic material 3 is a tablet-molded body, it becomes easier to control the range of temperature changes depending on the usage environment and usage conditions, so low-temperature burns can be prevented when the temperature of the exothermic material 3 rises too much.

The area of the tablet-molded body of the exothermic material 3 in front view is not particularly limited, but is, for example, 200 mm ² or more and 500 mm ² or less, preferably 250 mm ² or more and 450 mm ² or less, and 300 mm ² or more and 400 mm ^{2 or less} . The following are more preferred. If the above-mentioned area of the tableted body of exothermic material 3 is less than 200 mm ² , there is a possibility that a sufficient effect for relieving nasal congestion may not be obtained, and if it exceeds 500 mm ² , a large amount of exothermic material 3 will be required. Manufacturing costs may increase.

The exothermic material 3 does not necessarily have to be in the form of a tablet compact, and may be in the form of powder or the like.

The heat generation property of the heat generating material 3 is not particularly limited, but the maximum heat generation temperature is, for example, 43° C. or higher and 65° C. or lower, preferably 43° C. or higher and 60° C. or lower, and 43° C. or higher and 55° C. or lower. is more preferred. If the maximum temperature is less than 43°C, it may not be possible to warm the nose and the vicinity of the nose to about 43°C, which is necessary to improve blood flow, and if it exceeds 65°C, low-temperature burns may occur. be.

The duration is, for example, 10 minutes or more and 3 hours or less, preferably 10 minutes or more and 2 hours or less, and more preferably 10 minutes or more and 1 hour or less. If the duration is less than 10 minutes, the effect of relieving nasal congestion may not be sufficiently obtained. Manufacturing costs may increase.

The rise time is, for example, within 60 seconds, preferably within 50 seconds, more preferably within 40 seconds. If the rising time exceeds 60 seconds, it may be difficult to quickly relieve nasal congestion after wearing the nasal passage improving tool 1 .

It should be noted that the heat generating material 3 may be made of a material other than a material that generates heat upon contact with air. For example, a material that generates heat when irradiated with microwaves in a microwave oven or the like (for example, ceramic powder such as ferrite) may be used.

Adhesive layer The adhesive layer 4 is a portion having adhesiveness on the back surface of the base material 2 (the back surface of the back side member 7 ), and the base material 2 is attached to the nose or the vicinity of the nose via the adhesive layer 4 . The adhesive layer 4 is formed by applying an adhesive, for example, to the back surface of the base material 2 (the back surface of the back-side member 7). As the adhesive, an acrylic adhesive, a urethane adhesive, a silicone adhesive, or the like, which has an adhesive effect on the skin, can be used. From the viewpoint of reducing irritation to the skin, it is preferable to use a silicone adhesive. preferable.

The adhesive strength of the adhesive layer 4 is not particularly limited, but is preferably 3N or more and 8N or less, more preferably 4N or more and 7N or less. The adhesive strength of the adhesive layer 4 can be measured using the adhesive tape/adhesive sheet test method specified in JIS Z 0237:2009.

The adhesive layer 4 may be formed on the entire back surface of the base material 2 (the back surface of the back surface member 7), but preferably, the back surface of both ends of the base material 2 (the pair of holding portions 8) is formed with adhesiveness. There is a non-stick area 81 without The non-adhesive area 81 is formed, for example, by not applying an adhesive only to the part of the back surface of the base material 2 (back surface of the back side member 7) that is to be the non-adhesive area 81. It can be formed by forming the adhesive layer 4 on the entire area of the back surface of the member 7 and then applying a non-adhesive substance on the portion of the adhesive layer 4 to be the non-adhesive region 81 .

Non-Adhesive Areas At least one non-adhesive area 81 is present on each of the pair of holding portions 8 at both ends of the substrate 2 . The shape of the non-adhesive region 81 is not particularly limited, and can be various shapes. When the non-adhesive layer 81 is present on the back surface of the holding part 8, the entire area of the holding part 8 is not attached to both sides of the base of the nose during use, and the non-adhesive area 81 does not restrict the skin. Therefore, when the face moves such as blinking or opening and closing the mouth during use, the restraining force of the holding part 8 against the movement of the face is relaxed, so that the skin is pulled when the face moves. It is possible to suppress the occurrence of skin tension.

Although the area of the non-adhesive region 81 is not particularly limited, it is preferably 5 mm ² or more and 200 mm ² or less, more preferably 5 mm ² or more and 110 mm ² or less. As a result, the holding portion 8 can be attached to the skin by the adhesive layer 4 so as not to be easily peeled off from the skin, and the above-described effects of the non-adhesive region 81 can be exhibited satisfactorily.

Although the non-adhesive region 81 is not particularly limited, it preferably exists in the upper portion of the holding portion 8 in the longitudinal and width direction, as in the present embodiment. The upper portion of the holding portion 8 in the longitudinal width direction is a portion above the center of the holding portion 8 in the longitudinal width direction. The nasal passage improving device 1 is often used during sleep, in which case the eyes are closed, but when the nasal passage improving device 1 is worn on the nose, the eyes are open, so it is difficult to wear. The shape (skin condition) of the face (especially under the eyes) differs depending on the time and use. Therefore, since the non-adhesive region 81 exists in the upper portion of the holding portion 8 near the eyes during use, the above-described effects of the non-adhesive region 81 can be further exhibited.

Although the non-adhesive region 81 is not particularly limited, it is preferably located above the extension line EL1 of the upper edge 90 of the extension portion 9 in the holding portion 8 in the longitudinal width direction as in the present embodiment. . The extension part 9 in the central part of the base material 2 is deformed in the direction of peeling off (jumping up) from the nose in order to return to its original shape due to the elastic restoring force when it is bent in a mountain shape along the shape of the nose during use, thereby filling the nasal cavity. spread. This deformation of the extension part 9 in the direction of peeling off from the nose exerts a force on the holding part 8 connected to the extension part 9 in the direction of peeling off from the skin. Since the lower edge 91 is parallel, the holding portion 8 receives a large force in the peeling direction from the skin between the extension line EL1 of the upper edge 90 of the extension portion 9 shown in FIG. 3 and the extension line EL2 of the lower edge 91. works. For this reason, the holding portion 8 is formed with the adhesive layer 4 over the entire area between the extension line EL1 of the upper edge 90 of the extension portion 9 and the extension line EL2 of the lower edge 91 of the extension portion 9, so that the pair of holding portions can be separated during use. 8 can be suppressed from coming off the skin, and the presence of the non-adhesive region 81 above the extension line EL1 of the upper edge 90 of the extension 9 further enhances the above-described effects of the non-adhesive region 81. can demonstrate.

The non-adhesive area 81 is not particularly limited, but preferably includes at least a portion of the outer peripheral edge 80 of the holding part 8 as in the present embodiment. In the present embodiment, as shown in FIG. 3 , of the outer peripheral edge 80 of the holding portion 8, the outer peripheral edge positioned above the extension line EL1 of the upper edge 90 of the extension portion 9 is included in the non-adhesive area 81. ing. Since the non-adhesive region 81 exists so as to include at least a part of the outer peripheral edge 81 of the holding part 8 in this way, the release sheet 5 can be easily peeled off from the back surface of the base material 2 from the non-adhesive region 81 . be able to.

Release Sheet The release sheet 5 covers and protects the adhesive layer 4 until the nasal passage improver 1 is used. The release sheet 5 is formed, for example, by applying a silicone-based release agent to paper, a resin film, a fiber sheet, or the like. The release sheet 5 is formed in the same shape and size as the base material 2 so as to cover the entire back surface of the base material 2 (the back surface of the back side member 7).

How to Use the Tool for Improving Passage Through the Nose Next, a method for using the tool for improving passage through the nose 1 of the present embodiment will be described.

When using the nasal passage improving tool 1, first, the nasal passage improving tool 1 is taken out of the air-impermeable bag, and the release sheet 5 is peeled off from the back surface of the base material 2. - 特許庁Then, as shown in FIG. 5, the expanded portion 9 (central portion of the base material 2) at the center in the width direction is attached to the nose so as to straddle the nose to the left and right, and the pair of holding portions 8 (base material) at both ends in the width direction are attached to the nose. 2) are attached to both sides of the base of the nose and set on points called nasal passages.

As a result, the pair of holders 8 set on both sides of the base of the nose expands the nasal cavity by the elastic restoring force of the expansion part 9 (the central part of the base material 2) bent in a chevron shape along the shape of the nose. (Both ends of the base material 2) warm the nose and nasal passages with the heating element 3. - 特許庁As a result, the nasal passage improving tool 1 of the present embodiment can improve passage through the nose and improve symptoms of nasal congestion.

Functions and effects of the nasal passage improving device The nasal passage improving device 1 of this embodiment is characterized in that the base material 2 has elasticity over the entire length in the width direction.
