Description

The present invention relates to a non-woven fabric sanitary mask, and particularly to a sanitary mask that significantly reduces stuffiness and stuffiness caused by wearing the mask.

Traditionally, masks have been used to prevent colds, hay fever, and dry throat, but recently, from the perspective of preventing the spread of new coronavirus infections, people have been forced to wear masks for long periods of time. .. However, wearing a mask makes you feel stuffy and stuffy, and your glasses become cloudy. Therefore, it has long been required to reduce or eliminate the discomfort caused by wearing a mask.

Various masks have been disclosed so far in order to reduce the discomfort caused by wearing the mask (see, for example, Patent Documents 1 to 4). The mask disclosed in Patent Document 1 is a mask in which ear straps are attached to both ends of the mask body, and the convex portion that directly contacts the face and the exhaled nausea on the peripheral edge of the mask body and the inner surface are lowered. It is characterized in that a recess for guiding is provided.

According to the mask disclosed in Patent Document 1, since the nausea when wearing the mask has a large resistance at the inner surface convex portion of the mask body, it is discharged from other than the inner surface convex portion of the mask body and from the lower discharge port. It is stated that nausea will not be trapped inside the main body and dew will not form, and the glasses will not be fogged.

Further, the three-dimensional cloth mask disclosed in Patent Document 2 has a mask main body and a hanging string 2, and the mask main body is sewn with a front cloth and a back cloth to create a space for passing the hanging string 2 on the left and right, and the hanging string 2 is passed through the mask main body. , The upper part of the mask body is curved to fit three-dimensionally so that there is no gap between the cheek and nose, and the lower part of the mask body is sewn straight without a curve and touches the skin of the lower jaw. It is characterized by creating a gap so that there is no gap.

According to the three-dimensional cloth mask disclosed in Patent Document 2, when the mask is worn, the mask is in contact with the shape of the base of the nose, the lower jaw avoids the contact between the mask and the skin, and dust is prevented from entering from the upper part of the mask to prevent splashing. It is also described that it is possible to improve the air passage by avoiding contact with the mask of the lower jaw, which makes breathing easier and gives a cool feeling, and is a shape that can be worn for a long time.

Further, the three-dimensional mask disclosed in Patent Document 3 is composed of a mask main body and a sheet cup attached to the inside of the mask main body, both members are formed of a breathable non-woven fabric, and the mask main body is a non-woven fabric. A cover portion that covers the mouth and the nose hole and ear hook portions that are connected to the left and right ends of the cover portion are formed, and the sheet cup is made of a non-woven fabric having lower elasticity than the mask body, and at least. It covers the nose and mouth and is formed to have a shorter vertical length than the cover portion, and is formed between the upper edge portion of the seat cup and the upper edge portion of the cover portion and the lower edge portion of the seat cup. A pair of left and right reinforcing pieces formed in a strip shape made of a synthetic resin material having flexibility and inelasticity are formed so as to form a band portion between the cover portion and the lower edge portion of the cover portion. The seat cup is attached so as to overlap the seat cup at a predetermined interval along the left and right upper ends of the seat cup so that the reinforcing piece is located on the upper part of the left and right nose when the seat cup covers the mouth. The reinforcing piece reinforces the upper edge portion of the seat cup and bends along the curved shape of the nose portion so that the upper edge portion of the seat cup is in close contact with the face.

According to the three-dimensional mask disclosed in Patent Document 3, even if the mask body is hung on the ear and the cover portion presses the seat cup toward the skin, the seat cup can be kept in shape without being crushed, and the mouth and the mouth. Since the space between the inside of the seat cup is not crushed, conversation and breathing can be easily performed, and the upper and lower bands formed by the mask body are in close contact with the face surface. It is stated that the high-density non-woven fabric in the part can capture pollen and the like mixed in the air and prevent fine powder such as pollen from infiltrating into the space between the nose and mouth and the inner side surface of the seat cup. Has been done.

Further, the mask described in Patent Document 4 is a mask provided with a covering portion for the wearer's mouth and nose muscle, and has a band-shaped member made of a plastically deformable synthetic resin and a lower rigidity and a size than the covering portion. The strip-shaped member is fixed only to the cover material and arranged on the non-skin side surface of the covering portion, and the cover material covers the non-skin side surface of the strip-shaped member. Arranged on the non-skin side surface of the covering portion, each of the strip-shaped member and the covering material extends along the upper end portion of the covering portion, and on both sides of the vertical center line that divides the covering portion into left and right. It is a pair of left and right sides, and is characterized in that it is arranged on both sides of the vertical center line with a predetermined interval in the lateral direction.

According to the mask disclosed in Patent Document 4, it is possible to prevent gaps from being formed on both sides of the nose muscle when worn, it is possible to provide a mask with an improved wearing feeling, and it is possible to maintain the shape when an external force is applied. It is stated that it is possible to provide a mask with improved sex.

According to the mask disclosed in Patent Document 1 and the three-dimensional cloth mask disclosed in Patent Document 2, the wearer's exhaled breath is easily discharged from below the mask, and the wearer feels uncomfortable such as breathlessness when wearing the mask. It is thought that the reduction of the problem will be achieved. However, even the masks disclosed in Patent Documents 1 and 2 have no rigidity as long as the material is a non-woven fabric or cloth, and it is difficult to maintain the shape of the mask body for a long time. I think there is something. If the three-dimensional shape of the mask body cannot be maintained due to external force such as exercise or wind pressure, the mask will stick around the nostrils and mouth, and it will be difficult to eliminate discomfort such as stuffiness and stuffiness.

Further, according to the three-dimensional mask disclosed in Patent Document 3 and the mask disclosed in Patent Document 4, gaps are less likely to occur from the nose to the cheeks, and the mask is worn by improving shape retention even though it is made of non-woven fabric. It is thought that discomfort such as suffocation at times can be alleviated to some extent. However, since the masks disclosed in Patent Documents 3 and 4 have a structure that completely covers the nose and mouth like the conventional masks, it is difficult to obtain the effect of eliminating discomfort when worn. I think it's a thing.

Therefore, in view of the above problems, the inventor of the present application is a sanitary mask capable of positively releasing exhaled air from below the mask by securing a space around the nostrils and the mouth while preventing the leakage of exhaled air from the upper part of the mask. As a result of diligent studies to provide the above, the present invention was reached.

That is, the non-woven sanitary mask of the present invention has a mask body composed of a left side surface portion and a right side surface portion, an ear hook portion extending to each rear end edge of the left side surface portion and the right side surface portion, and the left side surface portion. And the upper shape holding member disposed across the center line in the left-right direction from the upper end portion of the center line of the mask body formed by each front end edge of the right side surface portion, and the left-right direction from the lower part of the center line. A lower shape holding member arranged across the center line, and arranged across the center line in the left-right direction from the center line between the upper shape holding member and the lower shape holding member. It is composed of one or a plurality of intermediate portion shape-retaining members, and the center line is gently curved diagonally downward from the front protruding portion and a front protruding portion slightly protruding diagonally downward from the upper end portion. It is characterized by including a bulging portion that bulges forward while forming a curved protruding portion in the vicinity of the upper end portion on the upper end edge of the mask body.

According to the sanitary mask of the present invention, it is possible to eliminate discomfort such as breathlessness and stuffiness when wearing the mask, and it is possible to prevent exhaled breath from leaking from the upper end edge of the mask body from the nose to the cheek. In particular, a front protrusion in which the center line of the mask body according to the present invention slightly protrudes diagonally downward from the upper end portion and a bulge portion that bulges forward while gently curving diagonally downward from this front protrusion. Since each shape-retaining member is arranged at a predetermined position on the mask body, a strong space is formed around the tip of the nose and the mouth when the sanitary mask of the present invention is worn. , The open state below the mask body can be maintained firmly. Therefore, the three-dimensional shape of the mask body can be maintained even when there is a pressure difference between the inside and outside of the mask due to vigorous breathing during exercise, or when an external force such as wind pressure acts, and the nostrils and mouth are maintained by the mask body. Can be prevented from being blocked. Since the exhaled breath is surely discharged from the lower part of the mask body, the discomfort such as stuffiness and stuffiness can be greatly reduced. Furthermore, since the area around the mouth and the chin are not in contact with the mask body, the mask body is less likely to shift and conversation is easier.

Further, since a curved protrusion is formed in the vicinity of the upper end of the center line at the upper end edge of the mask body according to the present invention and the upper shape holding member is arranged, the side surface of the nose is under the eyes (cheek). The mask body can be attached along the line above), and it is difficult to create a gap between the upper edge of the mask body and the face. Since the exhaled air can be reliably discharged from below the mask body, it is possible to prevent the exhaled air from leaking from the upper end edge of the mask body, and the spectacle wearer can obtain the effect of preventing fogging of the spectacles.
