Abstract

PROBLEM TO BE SOLVED: To improve a feeling of wearing of a nose plug mounting tool, using the very high elasticity of a shape memory alloy. SOLUTION: Both ends of a U-shaped device 11 are folded down to form hook-shaped portions 12. The U-shaped tool 11 is inserted into the nostrils and pinchingly holds the bridge, and the hook-shaped portions 12 are inserted into the nose plugs 2 and support the nose plugs 2 inserted into the nostrils. The U-shaped tool 11 is formed of a shape memory alloy, and the hook-shaped portions 12 are formed of a resin such as a plastic. When manufacturing a nose plug mounting tool 1, the U-shaped tool 11 and the hook-shaped portions 12 are integrally compositely formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nose plug that protects the nasal cavity by filtering harmful substances such as pollen and soot dust contained in exhaust gas that cause allergic rhinitis, and more particularly to a wearing tool thereof.

[0002]

In the nose plug mounting device, a U-shaped device made of an elastic material is used to clamp the nasal bridge that divides the left and right nostrils to fix it to the nose, but if the U-shaped device is loosely tightened. The nose plug slips or slips out. Also, if the U-shaped device is tightened too tightly, a feeling of pressure is felt and the wearing comfort becomes poor, and blood circulation is obstructed when worn for a long time.

Shape memory alloys, on the other hand, have the unique property of returning to their original shape by being heated even if they are deformed, and in a certain temperature range, even if they are greatly deformed beyond the elastic limit, they have zero tensile force. When it is returned to the original shape, it has the property of returning to its original shape and dimension. The property called superelasticity of this shape memory alloy brings about very large stretchability, and has recently been applied to the processing of brassieres and the like.

Therefore, the present invention has been made for the purpose of making the wearing feeling of the nose plug fitting more comfortable by utilizing the very large elasticity of the shape memory alloy.

[0005]

In order to achieve the above object, the present invention has the following constitution.

That is, according to the first aspect of the present invention, both ends of the U-shaped device for sandwiching the nasal bridge are folded back downward to form a hook-shaped portion, and a nose plug is inserted into the hook-shaped portion to support it in the nostril. A nasal plug fitting, wherein the U-shaped device is formed of a shape memory alloy. The invention of claim 2 is the nose plug fitting according to claim 1, wherein an upward barb is projected on either or both of the U-shaped device and the hook-shaped part. The invention of claim 3 is
The nose plug fitting according to claim 1, wherein the nose plug is impregnated with an aromatic liquid.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a front view of a nose plug fitting according to the present invention. The nose plug fitting 1 has a hook portion 12 formed by folding back both ends of a U-shaped device 11 downward. U-shaped device 11
Is inserted into the nostril to sandwich the nasal bridge, and the hook-shaped portion 12 pierces the nose plug 2 to support the nose plug 2 inserted into the nostril.
Further, the U-shaped device 11 is formed of a shape memory alloy, and the hook-shaped portion 1
2 is made of resin such as plastic. When the nose plug fitting 1 is manufactured, the U-shaped device 11 and the hook 12
Are integrally compounded. Further, upward barbs 13 are respectively projected on the outside of the U-shaped device 11 and the inside of the hook-shaped portion 12.

As shown in FIG. 2, the nose plug 2 is formed by bundling acetate long fibers a in a columnar shape and coating the outer periphery thereof with a polypropylene nonwoven fabric b. The nose plug 2 is impregnated with the herb liquid to have an aromatherapy effect.

The nasal plug fitting according to the present invention is constructed as described above. First, the hook-shaped portion 12 is inserted into the nostril and the nasal bridge is clamped by the U-shaped device 11 to mount the nasal plug fitting 1 on the nasal bridge. Fix on the nose.
Next, in this state, the nose plug 2 is pierced into the hook-shaped portion 12 and inserted into the nostril, and the tip surface is locked to the folded back portion of the hook-shaped portion 12 so that the nose plug 2 does not enter deeper into the nostril. . Moreover, the nose plug 2 inserted into the nostril is prevented from coming out of the nostril by being disturbed by the upward barb 13. When the nose plug fitting 1 is attached to the nose, the air passing through the nostrils by breathing flows through the gaps of the long fibers a bundled along the length direction of the nose plug 2, and foreign substances such as pollen and dust are long between them. It adheres to the fiber a and is removed.

[0011]

As described above, in the nose plug fitting of the present invention, the U-shaped device for holding the nasal bridge is made of a shape memory alloy. Therefore, according to the present invention, the super-elastic shape memory alloy fits tightly in the nasal bridge and is strongly tightened. However, since the expansion and contraction is large, the contact is soft, and a firm fit feeling is obtained while being soft.

Further, in the nose plug fitting of the present invention, an upward barb is projected on either or both of the U-shaped device and the hook-shaped portion. Therefore, according to the present invention, the nose plug inserted into the nostril is prevented from falling off due to the barb.

In the nose plug fitting of the present invention, the nose plug is impregnated with the aroma liquid. Therefore, according to the present invention, especially for people with hay fever, etc., their heads often do not have a clear head, which can make the person feel refreshed.
