Description

The present invention relates to a mask that covers the wearer's mouth and nose.

Conventionally, in order to prevent the inhalation of pollen, viruses and the like, a mask (also referred to as a sanitary mask) made of a breathable cloth has been used.
When using a mask, if there is a gap between the mask and the face of the wearer of this mask, pollen, viruses, etc. will flow in through this gap, so the mask should be placed on the face so that no gap is created. It was necessary to bring them into close contact. However, if the degree of adhesion between the mask and the face is increased, there is a problem that the mask becomes stuffy and hot in the summer.
Therefore, the techniques of Patent Documents 1 and 2 shown below have been proposed.

The stuffiness preventive device for masks disclosed in Patent Document 1 is used by being worn under a conventional mask, and has an opening at least in the corresponding portion between the nose and the mouth, and can cover substantially the lower half of the face. It is formed of a composite sheet having a large size and a bonding of an upper layer having heat insulating properties and moisture permeation suppressing properties and a lower layer having hygroscopic properties.
The mask disclosed in Patent Document 2 is formed in a bag shape by at least a part of a breathable outer sheet and an inner sheet, and an opening for connecting a mask nose adapter communicating with the inside of the bag shape to the inner sheet. Is formed to enable smooth breathing and suppression of stuffiness.

Subsequently, the embodiment in which the present invention is embodied will be described with reference to the attached drawings, and the present invention will be understood.
As shown in FIGS. 1 to 3, the mask 10 according to the embodiment of the present invention is made of a breathable non-woven fabric (an example of fabric) covering the mouth portion 12 and the nose portion 13 of the wearer 11, and has a nose. It is possible to suppress and further prevent heat buildup around the mouth portion 12 due to exhalation from the portion 13.
The details will be described below.

The mask 10 has a mask body 14 that covers the mouth portion 12.
The mask main body 14 is made of a non-woven fabric, has a rectangular shape (rectangular shape) when viewed from the front, and has a plurality of pleated portions 15 that can be spread in the vertical direction.
The size of the mask body 14 depends on the wearer (adults (men and women) and children) who use the mask 10, and is not particularly limited. For example, the length on the long side (the length on the long side) ( Width) W1 is about 12 to 20 cm (preferably lower limit 13 cm, upper limit 18 cm), short side length (height) L1 is shorter than length W1 7 to 12 cm (preferably lower limit 8 cm, upper limit) Is about 10 cm).

A notch 16 into which the nose portion 13 is inserted is formed in the upper center of the mask body 14.
The notch 16 has a U-shape (or V-shape) when viewed from the front, and when the mask 10 is worn, at least the nasal column, ala of nose (small nose), and tip of the nose (tip of the nose) of the nose 12 are inserted. It is about the size (and may include part or all of the nasal bridge (nasal muscle)). Specifically, the depth d of the deepest notch position (opposite position of the nasal column) of the notch 16 is, for example, about 2 to 4 cm from the upper end position of the portion where the notch 16 is not formed. The inner width w of the notch 16 is the widest portion (upper end position of the mask body 14), and is, for example, about 3 to 8 cm (preferably, the lower limit is 4 cm and the upper limit is 7 cm).

Ear straps 18 to be hung on the ears 17 are provided on both sides (both sides) of the mask body 14 in the width direction.
The ear strap 18 is made of, for example, polyester, polyurethane, rubber, or the like, and has a length of, for example, about 14 to 20 cm (preferably, the lower limit is 16 cm and the upper limit is 18 cm), and the ear strap 18 is semicircular when viewed from the front. It is fixed (crimped) to the mask body 14 so as to form an annular shape.
Further, instead of the ear hook string 18 described above, an ear hook portion made of the same material as the mask body 14 and integrally (continuously) with the mask body 14 can be used. In this case, an opening into which the ear portion 17 enters is formed in the central portion of the ear hook portion.

A nasal mask portion 19 that covers the nose portion 13 that has entered the notch 16 is provided on the upper surface of the mask main body 14.
The nasal mask portion 19 is made of a non-woven fabric, has a rectangular shape (rectangular shape) when viewed from the front, and has a plurality of pleated portions 20 that can be spread in the vertical direction.
The size of the nasal mask portion 19 depends on the wearer (adults (men and women) and children) who use the mask 10, and is not particularly limited, but for example, the length on the long side. The (width) W2 is shorter than the length W1 on the long side of the mask body 14 (for example, about 0.1 to 3 cm shorter, but may be the same), and the length (height) L2 on the short side is the mask body. The length on the short side of 14 is shorter than L1 (for example, L2 = about 4 to 7 cm).

The lower end of the nasal mask portion 19 is attached to the upper part of the front side of the mask body 14 at a position below the notch 16.
Specifically, the lower end of the nasal mask portion 19 is folded back inward (on the mask main body 14 side), and the folded portion 21 is fixed (crimped) to the upper surface side of the mask main body 14.
Further, the upper end portion of the nasal mask portion 19 protrudes upward from the upper end portion of the mask main body 14 when viewed from the front (it may be the same as the upper end portion of the mask main body 14), and in use, the wearer 11 Adhere to the face. For this reason, a shape-retaining core material (for example, a wire or wire made of shape-retaining plastic) is attached to the upper end of the nasal mask portion 19 along the width direction thereof.

In the nasal mask portion 19, the mask main body 14 forms an opening in which the back surface of the nasal mask portion 19 and the front surface of the mask main body 14 communicate with each other in the width direction of the nasal mask portion 19. The lower end of the nasal mask portion 19 is fixed to the upper part of the front side of the mask body 14 in a state of being bent on the surface of the mask body 14. This facilitates the formation of vents 22 on both sides of the mask 10 for main exhalation and inspiration from the nose 13. The main exhalation and inspiration from the nose 13 include, for example, exhalation and inspiration flowing out and inflowing through the nasal mask portion 19 made of a non-woven fabric, and outflow and inspiration from the gap between the nasal mask portion 19 and the face. Excludes inflowing exhalation and inspiration.
Here, the distance s between the lower end of the nasal mask portion 19 and the deepest cut position of the notch 16 is, for example, about 1 to 3 cm in consideration of the ease of exhalation and inspiration from the nose portion 13. Good.

The non-woven fabric constituting the mask 10 (mask body 14 and nasal mask portion 19) is a fibrous structure, and the fibers are entwined or stuck together (fibers are entwined or mechanically attached) by an adhesive, scientifically, or mechanically. It is a sheet-like material (entangled without weaving), and its material includes, for example, chemical fibers such as nylon, acrylic and polyester, and natural materials such as cotton, wool and silk. The cloth for the mask is not limited to the non-woven fabric, and may be a cloth (cotton, gauze, etc.) or silk woven with fibers.
Further, for attaching the nasal mask portion 19 to the mask main body 14, not only fixing (crimping) but also adhesion, stapler, sewing or the like may be used, and an appropriate selection can be made according to the material.

As shown in FIGS. 1, 3 (A) and 3 (B), when using the mask 10, the ear strap 18 is first held by both hands and the mask 10 is brought close to the face. Then, while inserting the nose portion 13 into the notch 16, the ear strap 18 is hung on the ear portion 17.
As a result, the portion of the mask body 14 below the notch 16 is brought into close contact between the mouth portion 12 and the nose portion 13, and the space covering the mouth portion 12 and the space covering the nose portion 13 are separated.
Further, the upper end portion of the nasal mask portion 19 is in close contact with the face, and vents 22 for performing main exhalation and inspiration from the nose portion 13 are formed on both sides of the mask 10.
Therefore, the structure is simple and the handling is easy, and it is possible to suppress or even prevent heat buildup around the mouth portion 12 due to exhalation from the nose portion 13.
