Abstract

A mask includes a mask body and a pressure strip. The mask body includes an outer layer and an inner layer superimposed on the rear side of the outer layer in a front-to-back direction. The pressure strip is connected to the mask body and is made of a flexible material. The pressure strip is adjacent to the upper edge of the mask body, and the cross section along an up-down direction is a continuous wavy curve. Since the cross section of the pressure strip along the up-down direction is a wavy curve, compared with the known flat strip structure, the new type can better adapt to the ups and downs of different nose shapes by increasing the points of contact with the nose bridge through the ups and downs of the wavy curve, thereby achieving the effect of improving the fit.

Description

Face mask

The invention relates to a mask, in particular to a mask with good fit.

Referring to FIG. 1 , a conventional mask comprises a body 11, a flat nose bar 12 disposed in the body 11, and two ear hooks 13 disposed on the left and right sides of the body 11. When wearing the mask, the user hangs the ear hooks 13 on the left and right ears respectively, and presses the nose bar 12 to fit the nose bridge, thereby covering the mouth and nose.

However, the fitting effect between the nose bridge bar 12 and the user's nose bridge is limited, resulting in poor overall fit. To improve the above problem, the existing improvement method is to add a second nose bridge bar 12 in the main body 11, and arrange the two nose bridge bars 12 in an upper and lower interval, thereby improving the fit of the nose bridge. However, although this improvement method can further improve the fit, the additional addition of the nose bridge bar 12 leads to an increase in manufacturing costs.

Therefore, the purpose of the present invention is to provide a mask with low cost and good fit.

Therefore, the novel mask includes a mask body and a pressing strip.

The mask body includes an outer layer and an inner layer overlapped on the rear side of the outer layer along a front-to-back direction.

The pressure strip is connected to the mask body and is made of flexible material. The pressure strip is adjacent to the upper edge of the mask body and presents a continuous wave curve along a cross section in an up-down direction intersecting the front-back direction.

The efficacy of this new product is:

1. Since the cross section of the pressure strip along the vertical direction is a wavy curve, compared with the conventional flat strip structure, the new type can better adapt to the ups and downs of different nose shapes by increasing the points of contact with the nose bridge through the ups and downs of the wavy curve, thereby achieving the effect of improving the fit.

2. In addition, compared with the conventional method of increasing the degree of fit by two nose strips, the present invention only requires one nose strip to achieve the effect of fit, and the manufacturing cost is relatively low.

Referring to FIG. 2 , FIG. 3 and FIG. 4 , a first embodiment of the novel mask comprises a mask body 2 , a pressure strip 3 , and two ear straps 4 .

The mask body 2 is a rectangular sheet body, and includes an outer layer 21 which is generally rectangular, an inner layer 22 which is generally rectangular and overlaps the rear side of the outer layer 21 along a front-to-back direction Y, and an inner space 20 which extends along a left-to-right direction X and is located between the outer layer 21 and the inner layer 22. The inner layer 22 is suitable for contacting the user's face.

The pressure strip 3 is connected to the mask body 2 and is made of a flexible material. In the first embodiment, the pressure strip 3 is disposed in the inner space 20 of the layer and is configured as an iron core. A general medical mask is usually composed of a three-layer structure consisting of an outer layer, a protective layer and an inner layer, and the space in which the pressure strip 3 is disposed in the above structure is common knowledge in the field. Therefore, a person with common knowledge in the field can infer the relevant structure and expanded details of the pressure strip 3 disposed in the inner space 20 of the layer based on the above description, and no further description is given here.

The pressure strip 3 is adjacent to the upper edge of the mask body 2, and the cross section along a vertical direction Z is a continuous wave curve. The vertical direction Z intersects the front-rear direction Y and the left-right direction X, and is substantially perpendicular to the front-rear direction Y and the left-right direction X.

The ear straps 4 are made of elastic material and are respectively arranged on the left and right sides of the mask body 2.

During implementation, the user first places the inner layer 22 toward the face and puts the ear straps 4 on the left and right ears respectively, and then presses the pressure strip 3 against the nose bridge to achieve the wearing function. Since the cross section of the pressure strip 3 along the vertical direction Z is a wavy curve, compared with the conventional flat strip structure, the first embodiment can better conform to the ups and downs of different nose shapes by increasing the points of contact with the nose bridge through the ups and downs of the wavy curve, thereby achieving the effect of improving the fit.

In addition, compared to the conventional method of increasing the fit by two nose strips, the first embodiment only needs one pressing strip 3 to achieve the fit effect, thus reducing the manufacturing cost.

It should be noted that in the first embodiment, the mask body 2 is generally a long rectangular sheet, but in other embodiments, the mask body 2 can also be designed as a three-dimensional mask or a fish-mouth mask, but is not limited to this.

Referring to FIG. 5 , FIG. 6 and FIG. 7 , a second embodiment of the novel mask is shown, which is similar to the first embodiment and also includes the mask body 2 , the pressure strip 3 and the ear straps 4 , but the difference is that:

The inner space 20 of the mask body 2 is omitted, and the pressure strip 3 is connected to the outer layer 21 of the mask body 2 and exposed to the outside.

In the second embodiment, the height fluctuation of the wave curve of the pressure strip 3 can also increase the contact point with the nose bridge, thereby achieving the effect of improving the fit.

Through the above description, the advantages of the above embodiments can be summarized as follows:

1. Since the cross section of the pressure strip 3 along the vertical direction Z is a wavy curve, compared with the conventional flat strip structure, the new type can better adapt to the ups and downs of different nose shapes by increasing the points of contact with the nose bridge through the ups and downs of the wavy curve, thereby achieving the effect of improving the fit.

2. Compared with the conventional method of increasing the degree of fit by two nose strips, the present invention only needs one pressing strip 3 to achieve the effect of fit, and the manufacturing cost is relatively low.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present patent.
