JP3660037B2 - Disposable sanitary mask - Google Patents

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]
Conventionally, as a disposable sanitary mask, a cover part for punching out a stretchable urethane foam sheet or non-woven fabric to cover the mouthpiece and nostril area, and an ear hook part, or a cup covering the mouthpiece There are those in which rubber strings are attached as ear hooks on the left and right sides of a plastic molded product.
[0003]
[Problems to be solved by the invention]
In the prior art mask, the ear-hanging portion may hang down and become entangled with each other when trying to wear it. In such a mask, it is necessary to loosen the entanglement of the ear hooks, which takes time and effort. In addition, at the production site of this type of mask, the mask may not be packaged unless the intertwined ear hooks are loosened beforehand. Furthermore, masks using urethane sheets or non-woven fabrics may be difficult to pick up masks one by one because the masks are in close contact with each other and cannot be individually identified when they are superimposed. .
[0004]
In view of this, the present invention has an object to make it difficult to hang down the ear-hanging portion of the disposable mask and to prevent the overlapping masks from being in close contact with each other.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, in this invention, a covering portion for at least mouth of the wearer consists of a ear-hook portion extending from the opposing both outer sides of said cover portion, said cover portion and ear shell and thermoplastic It is premised on a disposable sanitary mask that is composed of sheet members separately formed of non-woven fabric made of synthetic fibers, and in which the inner end portions of the cover portion of the sheet member are joined to each other .
[0006]
In such assumption, the with an outer end portion and a proximal portion of the ear shell of the cover part are connected by joining overlap, the thermoplastic synthetic fibers are melted at the outer surface of the overlapping portion The feature of the present invention is that a film-like smooth surface is formed by losing the fiber form, and the joining portion between the outer end portion and the base end portion is more rigid than the remaining non-woven fabric portion. It is.
[0007]
【Example】
The details of the disposable mask according to the present invention will be described with reference to the accompanying drawings.
[0008]
A mask 1 shown in a perspective view in FIG. 1 is provided on a cover 2 having a shape and size capable of covering the mouth of a wearer and the periphery of a nostril, and an ear formed by providing a slit in the portion of the nonwoven fabric. is composed of a pair of left and right ear shell 3 having a hole 5 for hanging, a proximal portion 7 of the outer side end portion 6 and the ear shell 3 of the cover part 2 overlap with the proximal portion 7 inward, The connecting portion 10 is formed by joining together. In the cover portion 2, the respective sheet members 2A and 2B constituting the left and right are integrated at a joint portion 4 extending in the vertical direction at the center of the mask 1 (inner end portions of the sheet members 2A and 2B) .
[0009]
The cover part 2 and the ear hook part 3 are each composed of a flexible nonwoven fabric containing thermoplastic synthetic fibers, preferably a nonwoven fabric containing 60% by weight or more of the fibers. In these connection parts 10, the overlapping nonwoven fabric is melted and integrated by being heated and pressurized. In this state, most of the synthetic fibers of the outer side end portion 6 and the base end portion 7 loses its form becomes a film shape and has a rigidity higher than the nonwoven portion of the residual. Further, the outer surface of the outer side end portion 6, the fibers form a smooth surface to melt.
[0010]
In the cover part 2, the non-woven sheet members 2 </ b> A and 2 </ b> B are heated and pressed to form a film to form the joint portion 4. The rigidity of the joining part 4 may be higher than the non-woven fabric part of the cover part 2 or the ear hook part 3, and may be higher or lower than the rigidity of the connecting part 10.
[0011]
As shown in the figure, the mask 1 configured as described above can maintain a state in which the mask 1 extends in the vertical direction due to the presence of the highly rigid connecting portion 10. Accordingly, the ear hook 3 made of a flexible non-woven fabric extends in the vertical direction at least in the vicinity of the connecting portion 10, and even if it hangs down, it is an imaginary line as shown in the side end portion of the portion 3. Limited to 13. Therefore, the mask 1 can effectively prevent the left and right ear hooks 3 from being entangled. In addition, the cover part 2 can maintain the state extended in the up-down direction by the joining site | part 4 and the connection part 10. FIG.
[0012]
In general, when a non-woven mask is overlapped, the constituent fibers of the non-woven fabric are entangled with each other, making it difficult to identify the masks one by one and pick them up. However, in this mask 1, since the nonwoven fabric melts at least on the outer surface of the connecting portion 10 to form a smooth surface, the overlapping masks 1 are not entangled here and can be easily identified one by one. Can do. Further, in the mask 1, when forming the connecting portion 10, can be an outer-side end portion 6 and a proximal portion 7 to melt the outer surface of the side end portion 6 and at the same time heat sealing to the smooth surface Yes, by doing so, the problems found in the prior art masks can be solved all at once.
[0013]
【The invention's effect】
In the mask according to the present invention, since the connecting portion where the covering portion and the ear hooking portion overlap has high rigidity and the outer surface of the connecting portion is smooth, the ear hooking portions on both sides are not entangled and worn or packaged. Easy. Moreover, even if the masks overlap each other, it is possible to easily identify each one.
