Abstract

PROBLEM TO BE SOLVED: To prevent a worn expendable mask from blocking the mouth and nostrils. SOLUTION: This expendable mask 1 made of a stretch thermoplastic synthetic fiber nonwoven fabric is provided with a cover section 2 capable of covering at least the mouth of a wearer and ear hook sections 3 extended backward from both the right and left sides of the cover section 2. Recesses 7 of relatively closely connected fibers are intermittently formed in the required range 10 of the cover section 2, and the stretch property of the range 10 is set lower than that of the ear hook sections 3.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-woven disposable hygiene mask, and more particularly to a disposable hygiene mask suitable for wearing by a doctor, a nurse in a hospital, or an operator in a food factory.

[0002]

2. Description of the Related Art Conventionally, a disposable hygiene mask is known in which an elastic sheet such as a urethane foam sheet is used to integrally form a covering portion and an ear hook portion for a wearer's mouth with a single sheet. . Since this kind of mask does not require labor for assembling it, it does not cost much and is suitable as a disposable mask.

[0003]

The above-mentioned known mask is
When the ear-hooking part is worn while wearing it, the cover part may be pulled leftward and rightward and may come into close contact with the mouth or nostrils, which may make it difficult to breathe.

Therefore, an object of the present invention is to prevent the covering portion of a disposable mask made of an elastic sheet from coming into close contact with the mouth or the like.

[0005]

In order to solve the above-mentioned problems, in the present invention, a disposable mask made of a non-woven fabric comprising a covering portion for at least the wearer's mouth and an ear hook portion extending on the opposite side of the covering portion. Is assumed.

On the premise, the non-woven fabric is made of thermoplastic synthetic fiber and has elasticity in at least the lateral direction of the mask, and the relatively densely joined portion of the synthetic fiber is the required range of the covering portion. It is a feature of the present invention that it is formed intermittently, and the elasticity of the required range in the lateral direction is lower than the elasticity of the ear hook portion.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the disposable mask according to the present invention will be described below with reference to the accompanying drawings.

A mask 1 shown in a perspective view in FIG. 1 contains crimped thermoplastic composite fibers and is made of a nonwoven fabric having elasticity in at least the front-back (transverse) direction of the mask 1, and the mouth and nostrils of the wearer. It has a cover portion 2 having a shape and size capable of covering the periphery, and an ear hook portion 3 which extends rearward from both left and right sides of the cover portion 2 and which can be worn around an ear. The mask 1 shown in the figure is composed of two non-woven fabrics integrally joined together at a joint portion 4 extending in the vertical direction at the center of the cover portion 2, and the ear hooking portion 3 is formed by providing a slit at that portion of the non-woven fabric. There is a hole 5 for hanging on the ear.

FIG. 2 is an end view taken along line II-II of FIG. In FIGS. 1 and 2, the central portion 10 occupying the required range of the cover portion 2 has a large number of concave portions 7 formed by intermittently heating and pressing the nonwoven fabric. In the recess 7,
Most of the crimped composite fibers are melted or fused closely to each other to lose elasticity, and the entire central portion 10 has lower elasticity and higher rigidity than the ear hook 3. . The joint portion 4 of the cover portion 2 is formed by melting and unifying two nonwoven fabrics under a higher temperature and pressure than when the recess 7 is formed. Here, the nonwoven fabric is formed into a film. Is changing.

The mask 1 thus constructed is preferably worn with the ear hook 3 extending in the front-rear direction. In this state, the cover 2 spreads laterally and swells, and its peripheral edge contacts the face. Even if the ear hook 3 is extended, the central portion 10 has low elasticity and high rigidity.
Hardly expands, and the bulge of the cover 2 can be maintained. As a result, when the mask 1 is worn, a relatively large space can be secured around the mouth and nostrils, and breathing can be performed easily. In addition to that, the cover portion 2 which swells to an appropriate size also helps to arrange the appearance of the mask 1. The joint portion 4 of the cover portion 2 is effective in maintaining such a bulge.

In the present invention, the individual shapes of the recesses 7 and their arrangement can be chosen so that they form the desired pattern on the cover 2. In particular, when the recess 7 is repeatedly formed in both the vertical and horizontal directions of the central portion 10 as in the illustrated example, and the uncompressed portion 7A is interposed between the concave portions 7, the central portion 10 is Even with low elasticity, it is possible to maintain an appropriate degree of flexibility, and the mask 1 having a good wearing feeling can be obtained.

[0012]

In the mask according to the present invention, the stretchable non-woven fabric forming the covering portion and the ear hooking portion is treated so that the covering portion has a low stretchability. A relatively large space can be obtained, which makes breathing easier. Therefore, it is suitable for a doctor, a nurse in a hospital, or a worker in a factory for manufacturing food or the like to wear for a relatively long time.

Claims (3)

[Claims] 1. A disposable mask made of a non-woven fabric, comprising a cover for at least a wearer's mouth and ear hooks extending from opposite sides of the cover, wherein the non-woven fabric is composed of a thermoplastic synthetic fiber. The mask has stretchability in at least the lateral direction, and the relatively densely joined portions of the synthetic fibers are intermittently formed in the required range of the cover portion, and the stretchability in the lateral direction of the required range is the above-mentioned. The mask has a lower elasticity than the ear hook. 2. The mask according to claim 1, wherein the densely bonded portion of the synthetic fiber is formed by intermittently heating and pressurizing the elastic nonwoven fabric. 3. The mask according to claim 1, wherein the densely bonded portions of the synthetic fiber are formed repeatedly in both the vertical and horizontal directions of the mask.
