Description

[0001]
[Industrial application fields]
The present invention relates to a disposable sanitary mask made of non-woven fabric, and more particularly to a disposable sanitary mask suitable for being worn by doctors, nurses, and workers in food manufacturing plants in hospitals.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, disposable sanitary masks that use a stretchable sheet such as a foamed urethane sheet to integrally form a cover portion and an ear hook portion for a wearer's mouth with a single sheet are well known. Since this type of mask does not require labor for assembling it, it does not cost much and is suitable as a disposable one.
[0003]
[Problems to be solved by the invention]
When the known mask is worn and the ear hook part is in a tension state, the cover part may be pulled to the left and right, and may become stuffy because it adheres to the mouthpiece or nostril.
[0004]
Then, this invention makes it a subject to prevent the cover part of the disposable mask which uses an elastic sheet as a raw material from adhering to a mouthpiece etc.
[0005]
[Means for Solving the Problems]
In order to solve the above problem, in the present invention, a covering portion for at least mouth of the wearer, a pair of mask members having the ear hook extending from opposing both outer sides of said cover portion is formed of a nonwoven fabric, wherein It is premised on a disposable sanitary mask in which the cover portions of the pair of sheet members are joined to each other at the inner edges thereof .
[0006]
Under such a premise, each of the pair of sheet members is a non-woven fabric of a thermoplastic synthetic fiber that is seamlessly continuous between the cover portion and the ear hooking portion and has elasticity in at least the lateral direction of the sheet member. Constructed, the sheet member in the cover is intermittently heated and pressurized in the vertical and horizontal directions to be provided with a recess that repeats intermittently in the vertical and horizontal directions of the sheet member, The synthetic fiber in the recess is more closely bonded than the synthetic fiber in the ear hook portion , whereby the stretchability of the cover portion in the lateral direction is expanded and contracted in the lateral direction of the ear hook portion. It is a feature of the present invention that the rigidity of the cover part is higher than the rigidity of the ear hook part .
[0007]
【Example】
With reference to the accompanying drawings, when describing the details of a disposable mask according to the present invention is as follows.
[0008]
A mask 1 shown in a perspective view in FIG. 1 includes a crimped thermoplastic conjugate fiber, and is formed from a pair of non-woven sheet members that are stretchable in at least the front-rear (lateral) direction of the mask 1. A cover portion 2 having a shape and a dimension capable of covering the mouthpiece and the periphery of the nostril, and an ear hook portion that extends continuously from the left and right sides of the cover portion 2 seamlessly and can be hung around the ear. 3. In the illustrated mask 1, a pair of sheet members of the nonwoven fabric are integrally joined at a joint portion 4 extending in the vertical direction at the center of the cover portion 2 (inner edge of each mask member) . There is a hole 5 for hanging on an ear formed by providing a slit in the portion of the nonwoven fabric.
[0009]
FIG. 2 is an end view taken along line II-II in FIG. 1 and 2, a central portion 10 occupying a required range of the covering portion 2 has a large number of concave portions 7 formed by intermittently heating and pressurizing the nonwoven fabric. In the concave portion 7, many of the crimped conjugate fibers are melted or closely welded to each other to lose stretchability, and the entire central portion 10 has lower stretchability and higher rigidity than the ear hook portion 3. Have. In addition, the joining part 4 of the cover part 2 is formed by melting and integrating the two nonwoven fabrics in response to a higher temperature and pressure than when the concave part 7 is formed. Here, the nonwoven fabric is in the form of a film. It has changed.
[0010]
The mask 1 configured as described above is preferably worn in a state in which the ear hooking portion 3 extends in the front-rear direction. In this state, the cover portion 2 expands to the left and right, and comes into contact with the face at the periphery. Even if the ear hook 3 is extended, the central portion 10 having low elasticity and high rigidity hardly extends, and the swelling of the cover 2 can be maintained. As a result, if this mask 1 is worn, a relatively wide space can be secured around the mouthpiece and nostril, and breathing can be performed easily. In addition, the cover 2 that swells to an appropriate size is also useful for adjusting the appearance of the mask 1. The joining part 4 of the cover part 2 is effective in maintaining such a bulge.
[0011]
In the present invention, the individual shapes of the recesses 7 and the arrangement thereof can be selected so that they form a desired pattern in the cover 2. In particular, when the concave portion 7 is repeatedly formed in both the vertical and horizontal directions of the central portion 10 as in the illustrated example, and the portion 7A that is hardly compressed is interposed between the concave portions 7, the central portion 10 is Even if it is low stretchable, it becomes possible to maintain moderate flexibility, and the mask 1 having a good wearing feeling can be obtained.
[0012]
【The invention's effect】
Mask, because there is stretchable nonwoven fabric forming the cover portion and the ear hooking portion is treated to be low-stretch the cover portion, a relatively wide space in mouth or nostrils periphery when worn according to the present invention And breathing becomes easier. Therefore, it is suitable for doctors, nurses, and workers in food manufacturing plants in hospitals to wear for a relatively long time.

Claims (4)

A cover portion for at least mouth of the wearer, a pair of sheet member having a ear hook extending from opposing both outer sides of said cover portion is formed of a nonwoven fabric, the cover portion of the pair of sheet members at its inner edge In disposable sanitary masks joined together ,
Each of the pair of sheet members is composed of a nonwoven fabric of thermoplastic synthetic fibers that is seamlessly continuous between the cover portion and the ear hooking portion and has elasticity in at least the lateral direction of the sheet member, The sheet member in the cover is intermittently heated and pressurized in the vertical and horizontal directions to provide a concave portion that repeats intermittently in the vertical and horizontal directions of the sheet member, and in the concave portion Synthetic fibers are tightly bonded as compared to the synthetic fibers in the ear hooks , so that the stretchability of the cover portion in the lateral direction is lower than the stretchability of the ear hooks in the lateral direction.
