Abstract

To provide a mask capable of suitably fitting to the nose.SOLUTION: A mask is used by hooking an attachment member 3 on the ear or the head of a user when wearing the mask, pressing a mask body 2 against the face of the user by utilizing its elastic force and bending a shape holding member 4 by the finger, thereby deforming it into a shape along the user's nose. With the deformation of the shape holding member 4 and the maintenance of the shape after the deformation, the mask body 2 and a suction member 5 follow the shape of the shape holding member 4 and maintain the same shape as that of the shape holding member 4. The suction member 5 closes the gap between the shape holding member 4 and the face with its weak elasticity, and is brought into close contact with the face by the elastic force of the attachment member 3.SELECTED DRAWING: Figure 2

Description

The present invention relates to a mask that fits well on the nose.

Conventionally, masks covering the user's face, particularly the mouth, nose, and their surroundings have been widely used for medical and sanitary purposes. In general, a mask consists of a rectangular planar mask body and attachment means such as ear straps attached to the sides of the mask body.

The mask main body is made of a sheet such as non-woven fabric, and has a planar shape unless an external force is applied thereto.

For this reason, in conventional masks, for example, as shown in Patent Document 1, a shape retaining member is attached to the mask body in order to maintain a state in which the mask body, which is a plane, fits the three-dimensional face. The three-dimensional shape of the mask body is maintained by this shape retaining member.

In a conventional mask, when an external force is applied to the shape-retaining member to deform it so as to form a recess corresponding to the undulations of the user's face, especially the protrusion of the nose, the shape is retained even when the external force is removed. Then, by aligning the concave portion of the shape-retaining member with the convex portion of the nose, the mask main body and the face are positioned, and then the mask main body is pressed against the nose exclusively by utilizing the tension and elastic force of the mounting means. This allows the mask main body to fit the nose and thus the face.

Japanese Patent Application Laid-Open No. 2011-30680

In conventional masks, the shape-retaining member merely positions the mask, and the tension or elastic force of the mounting means is exclusively used to fit the mask body to the nose.

For this reason, if the mask is worn continuously and the tension or elastic force of the attachment means is loosened, the mask body may no longer fit the nose.

As a result, pollen, dust, bacteria, viruses, and the like may enter through the gap between the mask body and the face. Moreover, especially when the user wears spectacles or the like, exhaled air may leak from the gap between the mask body and the nose, causing the spectacles to fog up. Therefore, if the tension or elastic force of the mounting means is strengthened, a new problem arises, such as pain in the ears.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and provide a mask that fits well on the nose.

A mask according to the present invention for achieving the above object is a mask comprising a mask body and a mounting member extending from the mask body, wherein the mask body is deformed when an external force is applied, and the external force is applied to the mask body. A shape-retaining member that retains the shape after deformation is arranged even if the is removed, and the surface of the mask body is deformed into a shape that follows the three-dimensional shape after deformation of the shape-retaining member, and is adsorbed to the skin. and an adsorption member is arranged, and the adsorption member and the shape retaining member overlap each other.

According to the mask according to the present invention, since it fits well on the nose, even when the user wears spectacles, exhaled air leaks through the gap between the mask body and the nose, causing the spectacles to fog up. no.

It is a front view of a mask. FIG. 4 is a cross-sectional view near the center of the upper peripheral edge of the mask body;

FIG. 1 is a front view of the mask 1, and FIG. 2 is a cross-sectional view of the mask main body 2 near the center of the upper peripheral edge. A mask 1 is composed of a mask body 2 , a mounting member 3 , a shape retaining member 4 and an adsorption member 5 .

The mask body 2 is made of a breathable and filtering sheet, such as a sheet material such as nonwoven fabric, gauze, or plastic having an open-cell structure, and is preferably made of a nonwoven sheet material.

A suitable material for the mask main body 2 may be selected according to the size of the target to be captured, such as pollen, dust, bacteria, and viruses.

The mask body 2 is preferably thin and planar, and when viewed from above, it may have a square, triangular, circular or similar shape, preferably a rectangular or similar shape. The mask main body 2 may adopt a shape that imitates the shape of the face, that is, a three-dimensional shape, instead of the planar shape.

The mask body 2 is composed of a first sheet 2a and a second sheet 2b which are superimposed, and these sheets 2a and 2b may be a combination of sheets of the same type, or may be sheets of different types. may be a combination of For example, the mask body 2 may be a combination of a nonwoven fabric sheet as the first sheet 2a and a nonwoven fabric sheet as the second sheet 2b.

A nonwoven fabric sheet as the first sheet 2a and a continuously foamed plastic sheet as the second sheet 2b may be combined without any problem. Also, the mask body 2 can be composed of a single sheet without stacking the sheets.

When the mask body 2 is composed of the first sheet 2a and the second sheet 2b, the mask body 2 is formed by fixing the peripheral edge of the first sheet 2a and the peripheral edge of the second sheet 2b by welding or the like. is configured.

The first sheet 2a and the second sheet 2b are superimposed to form an upper edge bonding portion 2c along the upper edge of the mask body 2, a lower edge bonding portion 2d along the lower edge, and a pair of side edge bonding portions along the side edges. 2e. As a method for bonding the upper end bonding portion 2c, the lower end bonding portion 2d, and the side end bonding portion 2e, an appropriate method such as performing adhesion, welding, or crimping while pressing is used.

The planar mask body 2 is folded along a plurality of horizontal folding lines 2f, and when the mask 1 is worn on the face, the folded portions bulge out according to the unevenness of the face. , is designed to have a three-dimensional shape.

The wearing member 3 is a member for the user to wear the mask 1, hooked on the ear or head of the user, and pressed against the face by utilizing its tension or elastic force. The mounting member 3 is made of a member having flexibility or stretchability, and is preferably made of natural fiber, natural rubber, or a polymer compound, and preferably made of an elastomer having flexibility and stretchability.

An appropriate material can be selected for the mounting member 3 according to the application. For example, it may be an ordinary thread cord or a rubber cord. It preferably consists of a thermoplastic elastomer which, at higher temperatures, has a higher viscosity contribution than elasticity.

The mounting member 3 is in the shape of a string or band, and extends from the left and right peripheral edge portions of the mask body 2 . The mounting member 3 alone or together with a part of the mask body 2 has a ring shape, and the mask body can be worn by passing the ear or head through the inside of this ring.

The shape-retaining member 4 arranged on the upper peripheral edge of the mask body 2 has a string-like or belt-like shape. It is sufficient that the shape retaining member 4 is arranged at least in the vicinity of the center of the upper peripheral edge of the mask main body 2, but it can also be arranged over the entire length of the upper peripheral edge. The shape-retaining member 4 is accommodated and fixed in a bag-like space formed between the upper end bonding portions 2c formed by two parallel perforations.

The shape-retaining member 4 deforms when an external force is applied, and retains the shape after deformation even when the external force is removed, that is, it has a shape-retaining property. The shape-retaining member 4 is made of metal or plastic having shape-retaining properties, preferably made of plastic having shape-retaining properties, and particularly preferably made of unstretched polyethylene terephthalate, for example.

As shown in FIG. 1, the adsorption member 5 arranged on the surface of the mask body 2 is for assisting the mask body 2 to fit the face by being adsorbed to the skin of the user's face.

Like the shape retaining member 4, the attracting member 5 is arranged at the upper peripheral edge of the mask body 2, and is arranged so as to overlap the shape retaining member 4 in plan view of FIG. Furthermore, the external shapes of the attracting member 5 and the shape retaining member 4 in plan view are substantially the same.

It should be noted that the adsorption member 5 does not need to have the same shape as the shape retaining member 4 as long as it overlaps with the shape retaining member 4, and may have a quadrangular, triangular, circular, or similar shape in plan view. . A rectangular shape or a shape similar thereto is particularly preferred, and a strip shape or a shape similar thereto is particularly preferred.

The adsorption member 5 is made of a polymer compound, preferably a polymer compound having a single-cell structure or a continuous-cell structure, and particularly preferably a polymer compound having a single-cell structure. In the case of having a cell structure, the rigidity can be weakened, the flexibility can be increased, and the adsorption force can be increased. In particular, when it has a single cell structure, it is possible to further increase the adsorption force.

The adsorption member 5 can be deformed into a three-dimensional shape after deformation of the shape-retaining member and a shape along the three-dimensional shape of the user's face, and has a weak elasticity that does not cause further deformation of the shape-retaining member.

Moreover, the adsorption member 5 has a surface that is wide enough to be in close contact with the user's face when deformed. Due to the structure and characteristics described above, the adsorption member 5 closes the gap between the shape-retaining member 4 and the face, and is pressed against the face by tension or elastic force of the attachment member 5 .

At this time, as described above, in addition to the adsorption effect of the fine bubble structure, the adsorption member 5 can be adsorbed to the face without being peeled off due to the action of surface tension caused by the adhesion of water contained in the user's exhalation. become.

The adsorption member 5 may be arranged along the entire circumference of the peripheral edge of the mask body 2 other than at the central portion of the upper peripheral edge. is preferably placed in As a result, the suction member 5 can maintain its three-dimensional shape by the shape-retaining material 4, can be brought into closer contact with the face, and can further enhance the suction force. Therefore, it is preferable that the adsorption member 5 is arranged at least in the central portion of the upper peripheral edge of the mask body 2 .

The shape retaining member 4 and the attracting member 5 overlap each other while being separated from each other with the first sheet 2a interposed therebetween. In the cross-sectional view near the center of the upper peripheral edge of the mask body 2 shown in FIG. They are stacked in order. Among these, the space between the adsorption member 5 and the first sheet 2a is fixed, and the space between the first sheet 2a and the shape retaining member 4 and between the shape retaining member 4 and the second sheet 2b are respectively fixed. It is not fixed.

In FIG. 2, the thickness of the first sheet 2a and the second sheet 2b is about 0.5 mm, the thickness of the shape retaining member 4 is about 0.4 mm, and the thickness of the adsorption member 5 is about 2 mm. It has a thickness of about 3.4 mm.

When using the mask 1, the wearing member 3 is hooked on the user's ear or head, and while the mask body 2 is pressed against the user's face using its elastic force, the shape-retaining member 4 is held by the finger. to bend it into a three-dimensional shape of the user's face, especially a shape along the nose.

Along with the deformation of the shape-retaining member 4 and the maintenance of the shape after the deformation, the mask body 2 and the adsorption member 5 also follow the shape of the shape-retaining member 4 and are maintained in the same shape. As a result, the adsorption member 5 closes the gap between the shape-retaining member 4 and the face due to its weak elasticity, and is pressed against the face by the elastic force of the attachment member 3 . In addition, since the elasticity of the adsorption member 5 is weak, the shape retaining member 4 is not deformed again.

As time elapses, moisture contained in the user's breath adheres to the surface of the adsorption member 5, thereby adsorbing the mask body 2 to the face and assisting in fitting the mask body 2 to the nose and the face.

Thus, according to the mask 1 of the present invention, since it fits well on the nose, exhalation leaks through the gap between the mask body 2 and the nose even when the user wears spectacles or the like. , does not fog up glasses, etc.
