Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mask that can be put on a nose.

[0002]

2. Description of the Related Art When a cold or hay fever occurs, a mask is usually put on to prevent cold outside air, external bacteria and pollen mixed with the air from entering the body. The mask generally comprises a main body made of a flexible material such as a square planar gauze, and ear straps attached to both sides of the main body. As the material of the mask main body, there is a material using a resin nonwoven fabric or the like for a disposable mask for surgery or various operations other than gauze. When the body part covers the nose and mouth and hangs the ear hanging string on both ears, the body part is pulled left and right by the pulling force of the ear hanging string, the body part is deformed into a shape along the outer surface of the face, The nose and mouth are covered by the body.

[0003]

When the conventional mask covers the chevron nose and the cheek following it, a gap is formed between the upper edge of the main body and the nose or cheek. Further, a gap is also generated between both side edges of the main body and the cheek. For this reason, there is a drawback that outside air that does not pass through the main body portion enters the nostril through a gap between the main body portion and the nose or cheek, and the effect of the mask that prevents invasion of pollen, cold virus, etc. cannot be sufficiently obtained. there were. Furthermore, in order to enhance the performance as a mask, a filter made of a slightly rigid material may be inserted into the main body, but in this case, a gap is further generated between the outer edge of the main body and the nose or cheek And
There is also a drawback that outside air that does not pass through the body enters the nostril through the gap, and the effect as a mask cannot be sufficiently obtained. The conventional mask has a drawback that, when talking while wearing the mask, the main body is shifted downward.
In a food factory or a place where there is a lot of dust, there is a problem that both hands are blocked, and the downward displacement of the main body cannot be corrected.

In order to correct this drawback, a deformable member such as a wire is put near the upper edge or both side edges of the main body, and the wire is deformed by hand to conform to the outer shape of the nose or cheek. There is provided a device in which the outer edge of the portion is closely attached to the outer shape of the nose or cheek so that no gap is formed between the outer edge of the main portion and the nose or cheek, and the main portion does not slip down. However, when a wire or the like is placed inside the main body, it takes a long time to perform shaping by hand, and furthermore, it has a drawback that it is difficult to store it in a bag or the like when not in use thereafter. In addition, when discarding the mask, in an area where the regulations for separating garbage are strict, non-burnable wires and the like must be separated from the main body, which is troublesome when discarding the mask.

[0005] When a person wearing glasses wears a mask, the user generally removes the glasses, then wears the mask, and then wears the glasses. That is, the mask is located inside and the glasses are located outside, and the upper edge of the mask is located higher than the frame at the lower edge of the glasses. With conventional masks, even if the lower edge of the frame of the glasses presses the upper edge of the mask, there is a gap between the mask and the nose and cheeks. When performed, there was a drawback that the breath leaked upward from the gap between the upper edge of the mask and the nose or cheek, and the inside of the glasses lens became cloudy, hindering surgery and various operations .

[0006] Conventionally, the body of the mask covers both the nose and the mouth. For this reason, there was a fault that talk and eating and drinking could not be performed freely. Further, in the case of a female person, there is a disadvantage that lipstick sticks to the mask. Furthermore, since the mask does not directly contact the nostrils to close the nostrils, invasion of pollen or cold virus from the nose cannot be more reliably prevented.

The present invention has been made in view of the above points, and greatly reduces the gap between the main body and the nose or cheek to enhance the effect of blocking the outside air and prevent the main body from slipping down. It is another object of the present invention to provide a mask that prevents the inside of the lens of the glasses from fogging for a person using the glasses.

Another object of the present invention is to directly cover the nostrils without covering the mouth, thereby enhancing the effect of blocking the outside air, and without having to feel breathless while wearing a mask, and to eat and drink. An object of the present invention is to provide a mask that allows a user to talk and that does not fog the spectacles for a person using the spectacles.

[0009]

In order to achieve the above object, a mask according to the present invention comprises: a main body for covering a mouth and a nose;
An ear strap for hanging the ear on both sides of the main body, a nose hook having a length in the vertical direction shorter than the length of the main body in the length direction, and a ventilation blocking member provided in the nose hook. The upper edge and both side edges of the nose hook portion are fixed to the upper edge and both side edges of the main body portion, and the lower edge of the nose hook portion is not fixed to the main body portion. The inside surface of the turned nose hook is hung on the back of the nose.

[0010] The mask according to the present invention further comprises a nose hook for hanging on the nose, a ventilation blocking member provided on the nose hook, and one lateral edge not fixed to the nose hook. A nose closing portion for fixing the rim and both side edges of the nose holding portion to the nose holding portion; and an ear hook string attached to either side of the nose holding portion or the nose closing portion. On the back of the nose so that the nose blocking portion covers the nostrils but does not cover the mouth.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a rear view of a mask according to the present invention, and FIG.
2 is an exploded perspective view of the mask of FIG. 1, and FIG. 3 is a sectional view taken along line AA of FIG. The mask 10 according to the present invention includes a main body 11
A nose hook 12 having an upper edge (or its vicinity) and both side edges (or its vicinity) connected or fixed to the back side of the main body 11, and a ventilation blocking member 13 provided in the nose hook 12
(FIG. 3) and an ear strap 14 attached to both sides of the main body 11.
It consists of: The length of the nose hook 12 in the vertical direction is set shorter than the length of the main body 11 in the vertical direction. Both the main body 11 and the nose hook 12 are made of a heat-weldable material such as a resin nonwoven fabric.

As shown in FIG. 3, a method for manufacturing a mask 10 according to the present invention includes one (or a plurality of) mask materials 1 for forming a main body 11 and a nose hook 12.
5 is prepared and the mask material 15 is wrapped around the ventilation blocking member 13 and bent into two (bending position P). One side edge of the ventilation blocking member 13 is made to match the bending position P of the mask material 15. Then, the ventilation blocking member 13
The mask material 15 is bent to one side at a position close to the other horizontal edge of the (bending position Q).

Next, as shown in FIG.
3 is applied to both side edges of the mask material 15 bent as shown in FIG. 3 from the front surface to the back surface.
And heat welding. At the time of this welding, the mask material 1 is positioned by positioning both ends of the ear hook string 14 at the welding location.
A mask 10 (FIG. 1) in which the 5, the backing member 16 and the ear strap 14 are integrally fixed is formed. Mask 10 shown in FIG.
In the figure, a nose hook 12 is present on the back side of the main body 11, the upper edge of the nose hook 12 is connected (bent) to the upper edge of the main body 11, and both side edges of the nose hook 12 are 11
Are welded and fixed to both side edges, and a ventilation blocking member 13 is provided inside the nose hook portion 12. In this state,
The lower edge of the nose hook 12 is a free edge 17 that is not fixed to the main body 11.

Next, when using the mask of the present invention,
As shown in FIG. 4, the free edge 1 which is the lower edge of the nose hook 12
Turning to the center of the nose 7 and the inside of the turned nose hook 12 as shown in FIG. 5, the nose (the tip of the back of the nose and the wings on both sides thereof)
Multiply by As shown in FIG.
When the central portion of 7 is lifted, the nose hook portion 12 has a three-dimensional mountain shape from the center portion to both sides, and the nose hook portion 12 is in a state of hanging just over the nose. Free edge 17 of nose hook 12
5, the free edge 17 of the nose hook 12 is pulled toward both sides when the mask 10 of the present invention is hung on the nose as shown in FIG. Therefore, the shape of the nose hook 12 matches the outer shape of the nose. Therefore, in the present invention, the gap between the nose and the main body 11 is very small as compared with the conventional flat mask, and the amount of air flowing in between the nose and the main body 11 without passing through the mask is reduced. Thus, the effect as a mask can be increased.

Further, as shown in FIG. 4, since both side edges of the nose hook 12 are fixed to the main body 11 by heat welding, when the center of the free edge 17 of the nose hook 12 is lifted, Is curved in an arc shape. As a result, both side edges in the vertical direction of the main body 11 (locations of the horizontal contact members 16) are deformed so as to be closer to the cheek of the face as compared with the conventional flat main body. As a result, the gap between the cheek and the main body 11 becomes very small, and the amount of air that does not pass through the space between the cheek and the main body 11 without passing through the mask is reduced, so that the effect as the mask is further improved. Can be done.

Further, the nose hook 12 is hooked on the back of the nose and the nose wings on both sides thereof, and a pulling force is applied to the free edge 17 of the nose hook 12, so that the nose hook 12 is hooked on the nose. As a result, even if the user speaks while wearing the mask 10, the main body 10 does not shift downward, and the vertical position of the mask is stabilized. Furthermore, since the ventilation blocking member 13 is provided inside the nose hook 12, the ventilation blocking member 13 prevents the breath from leaking upward from the nose hook 12. Therefore, when the person wearing the glasses 18 uses the mask 10 of the present invention, it is possible to prevent the conventional drawback that the inside of the lenses of the glasses 18 is fogged by moisture contained in breath. Further, if the ventilation blocking member 13 has a certain rigidity, it is possible to prevent the shape of the nose hook portion 12 from being deformed and to make the mask adhere to the nose exactly. In addition, for a person who frequently attaches and detaches the mask, the conventional mask does not clearly distinguish between the front and back sides, and there is a risk that the front and back sides may be reversed and the surface on which pollen or the like is adhered may be applied to the face. However, in the mask 10 of the present invention, since the surface of the main body 11 where the nose hook portion 12 is located is always in contact with the face, there is no possibility that the surface on which pollen or the like is adhered will hit the face. Also, by applying coloring or printing such as characters or patterns to the main body 11 or the nose hook 12, fashionability and economic efficiency as a mask can be improved.
