Description

  The present invention relates to a disposable sanitary mask, and more particularly to a disposable mask that can be suitably used by a spectacle user by preventing the exhaled air exhaled inside the mask from leaking upward.

  Recently, a sanitary disposable mask in which a mask part that can freely move around the mouth when worn and ear hooks extending from both sides of the mask part are integrally formed from a pair of non-woven blank sheets has been used. . Even with such a disposable mask, a gap is formed on the left and right edges of the mask portion that crosses the nose bridge, so that in the case of a spectacle user, exhaled air that has escaped from the left and right gaps of the nose bridge may cloud the spectacle lens. Many.

  Therefore, a sanitary mask has been proposed in which the peripheral edge of the mask body is brought into close contact with the face with an adhesive portion to eliminate a gap. For example, in Japanese Patent Application Laid-Open No. 2004-313397, a pair of blank sheets made of a non-woven fabric that can be repeatedly peeled off from the adhesive portion are joined, and the adhesive portions that closely adhere the peripheral edge of the mask body to the face are staggered. A provided sanitary mask is disclosed.

  According to the sanitary mask, the peripheral edge of the mask body can be adhered to the face by the adhesive portion, so that allergens contained in the outside air can be prevented from entering the inside of the mask. There is also a function to prevent fogging. However, since the skin respiration on the skin surface to which the adhesive portion provided at the periphery of the mask body is adhered is prevented, the uncomfortable feeling on the skin surface in the adhesive portion cannot be eliminated. Moreover, if the adhesive part is repeatedly attached to and peeled from the cheek surface, the adhesive force of the adhesive part is likely to be impaired, so that the attachment / detachment cannot be performed freely.

JP 2004-313397 A

  The present invention has been proposed in view of such points, and can easily perform breathing and conversation while having an airtightness to prevent the spectacle lens from being clouded by the exhaled breath inside the mask. An object of the present invention is to provide a disposable sanitary mask that can provide an appropriate fit.

  In order to solve the above problems, the present invention provides a filter part that covers a wearer's nose and mouth, an ear hook part that extends outward from the inner edge of the filter part, and a bulge part formed above the ear hook part. Is a disposable sanitary mask bonded to each other from the outer edge of the filter part to the upper edge of the bulge part, and the bulge part is in a state where the ear hook part is opened to the left and right A first aspect of the present invention is a disposable sanitary mask that is inclined downward to the face side and formed so as to contact the back of the nose when worn.

  Further, in the present invention, the disposable sanitation mask in which the bulging portion and the ear hooking portion are integrally formed of a nonwoven fabric having low rigidity and high stretchability compared to the filter portion. The sanitary mask is the second gist.

  In order to wear the disposable sanitary mask of the present invention, when the left and right ear hooks are pulled in the left and right directions, the bulge formed on the upper side of the ear hooks naturally follows the tensile force applied to the ear hooks. Bend down to the face side. When the disposable sanitary mask is worn, the bulging portion comes into contact with the back of the nose and the cheek surface so as to eliminate a gap between the cheek surface under the eyes or the periphery of the back of the nose and the upper end of the mask. Therefore, it is possible to prevent the exhaled air exhaled inside the mask from leaking upward.

  Further, in the case of a disposable sanitary mask in which the bulging portion and the ear hooking portion are integrally formed of a nonwoven fabric having low rigidity and high elasticity compared to the filter portion, the bulging portion is worn The adhesion to the back of the person's nose is improved, and it becomes easy to follow the tensile force applied to the ear hook, and it is surely bent downward to the face side. Therefore, the airtightness on the upper end side of the mask can be further increased. Moreover, when the bulging part and the ear hook part are formed of a non-woven fabric, the skin surface abutting on the mask is not hindered by skin respiration, which can remarkably improve the uncomfortable feeling of the skin surface when worn. Furthermore, since the bulging portion and the ear hooking portion are integrally formed, the manufacturing cost can be reduced.

  Next, an embodiment of a disposable sanitary mask of the present invention (hereinafter simply referred to as “mask of the present invention”) will be described in detail with reference to the accompanying drawings.

  1 to 4 show an embodiment of the mask of the present invention. FIG. 1 is a rear view of a mask 1 according to an embodiment of the present invention when the mask 1 is opened left and right. The mask 1 of the embodiment of FIG. 1 is formed by stacking two blank sheets 2 shown in FIG. 3 and welding the substantially arc-shaped outer edge end 11 of the filter portion 10 and the upper edge 23a of the bulging portion 23. The The blank sheet 2 shown in FIG. 3 includes a filter portion 10 and a mounting portion 20 as shown in FIG. 2, and is formed by welding the inner edge 12 of the filter portion 10 and the side edge 21 of the mounting portion 20. The

  The mounting portion 20 includes an ear hooking portion 22 in which a cutout hole 22 a is formed, and the bulging portion 23. The cutout hole 22a is for engaging with the left and right ears. In the present embodiment, the cutout hole 22a formed in the mounting portion 20 is an arc-shaped substantially parallelogram shape with smooth corners, but may have any shape such as a slit shape or a circular shape as necessary. Can be. If the cutout hole 22a is formed in a slit shape by cutting the mounting portion 20, unnecessary portions of the material can be reduced, so that the mask of the present invention can be provided at low cost.

  The bulging portion 23 is formed so as to protrude obliquely upward from a position above the ear hooking portion 22 of the mounting portion 20. In addition, as shown in FIG.1 and FIG.4, when wearing the mask 1 of the said embodiment, the bending part 23b of the bulging part 23 forms a mask upper end part. When the mask 1 is worn, the bulging portion 23 is bent downward from the bent portion 23b to the face side and comes into contact with the back of the nose and the cheek surface, thereby eliminating the gap between the buccal surface under the eyes or the periphery of the nose back and the bent portion 23b. By this, it has a function which prevents the exhaled breath exhaled inside the mask 1 from leaking upward. While the bulging part 23 is maintained in a state of being bent from the bent part 23b to the face side when worn, it is necessary not to interfere with breathing. Therefore, the size of the upper edge 23a to be welded is surely in contact with the back of the nose when the mask 1 is worn, and is the length to the tip of the nose, and the width from the bent portion 23b to the peripheral portion 23c is from the back of the nose to the nose wing. It is preferable to make the length to the extent that it abuts against. Specifically, in the case of an average Japanese mask, the dimension of the upper edge 23a and the width dimension from the bent part 23b to the peripheral part 23c are both about 1.5 cm to 3.0 cm.

  In the mask 1 of the above embodiment, when the left and right mounting parts 20 are opened in the left-right direction as shown in FIG. 1, the tensile force applied to the ear hooking part 22 acts downward on the welded upper edge 23a, A portion from the bent portion 23b to the peripheral edge portion 23c is naturally bent downward toward the face side. Then, as shown in FIG. 4, the wearer wears the mask 1 by engaging the notch hole 22a with the left and right ears while bringing the upper edge 23a bent to the face side into contact with the back of the nose. .

  Examples of the material used for the blank sheet 2 include a nonwoven fabric composed of synthetic fibers such as polyurethane fibers, polystyrene fibers, polyester fibers, and polyvinyl chloride fibers. In addition, when wearing the mask 1 of the above-described embodiment, it is necessary to secure a space between the mask 1 and the wearer's mouth or nostril for easy breathing and conversation. On the other hand, the left and right mounting portions 20 need to obtain an appropriate fit. Therefore, the filter unit 10 is preferably made of a material having higher rigidity than the mounting unit 20, and the mounting unit 20 is preferably made of a material having high stretchability. Moreover, since the bulging part 23 and the ear hook part 22 are integrally formed in the mounting part 20 in the mask 1 of the above embodiment, the mounting part 20 has lower rigidity and higher than the filter part 10. It is preferable to comprise the nonwoven fabric which has a stretching property.
