Abstract

PURPOSE: To prevent dispersion of ions, salts, or the like accompanying expiration mainly in a clean room and the like by containing a powdery macromolecular absorbent in an inner for a mask. CONSTITUTION: In an inner 3, contact cloth 4, a polyester wadding 5, a hot melt sheet 6, urethane foam 7, and outside cloth 8 are layered in this order from the side touching a mouth. Usually, cotton cloth comfortable to skin is used as the contact cloth 4. Water permeable urethane foam, in other word, a material which is excellent in water absorbing property and can be sunk underwater when it absorbs water to a certain extent is used as the urethane foam 7. A proper amount of a powdery macromolecular absorbent (polymer) is scattered on the urethane foam 7 and/or the polyester wadding 5. The inner 3 is applied on the inside of a mask main body 1 in use. In use, water in expired air is captured by the high macromolecular absorbent, though expired/inspired air passes through the inner 3.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inner mask, and more particularly to a mouth of a mask which is mainly used in a clean room or the like to prevent the scattering of ions, salts and the like accompanying the expiration. The present invention relates to an inner (inner cloth) used on the side in contact with.

[0002]

2. Description of the Related Art If dust adheres to a mask (in this case, a mask for manufacturing IC, etc.) in the manufacturing process of IC, LSI, etc., it may cause a fatal defect in the product. , Photo-etching, diffusion, epitaxial, etc. are performed in the clean room, and the worker wears dustproof clothing. Further, since moisture in the exhaled breath contains ions and the like, a cloth mask is put on to prevent the moisture from scattering. This mask should be replaced several times a day, and the used one should be discarded.

[0003]

As described above, in the prior art, the operator in the clean room often changed the mask many times a day, and the used masks were discarded, so that it was very unsatisfactory. It was an economy. In addition, the conventional masks do not give sufficient consideration to trap moisture in exhaled breath. Therefore, the present invention provides a practical and economical mask inner that separates a portion that comes into contact with the mouth and becomes dirty from the mask body, and that can reliably prevent the scattering of ions, salts, and the like in the breath. It is an issue.

DISCLOSURE OF THE INVENTION The present invention has solved the above-mentioned problems by using an inner mask for masks, which is characterized in that it contains a powdery polymer absorber. Preferably, the inner
Is formed by laminating breathable materials, one of the breathable materials is a hot melt sheet, and one of them is a water-immersible urethane foam.

[0005]

[Operation] The inner can be replaced because it is separate from the mask body. Moisture in the exhaled breath is reliably captured in the hygroscopic layer containing the polymer absorbent in the inner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described with reference to the accompanying drawings. In the figure, 1 is a mask body having an ear hook 2,
A conventional one may be used. Reference numeral 3 denotes an inner member that is applied to the inside of the mask body 1, that is, the side that contacts the mouth, and is configured separately from the mask body 1.

The inner member 3 comprises a contact cloth 4, a polyester cotton 5, a hot melt sheet 6, a urethane foam 7 and an outer cloth 8 which are laminated in this order from the side of the mouth. usually,
As the contact cloth 4, a cotton cloth having a soft touch is used.

As the urethane foam 7, a water-immersible urethane foam, that is, a urethane foam having a property of being excellent in water absorption and submerging in water when absorbing water to some extent is used. The urethane foam having such a property is used, for example, to grow radish radish. By using this type of urethane foam 7, the entire inner member has good hygroscopicity.

On the urethane foam 7 and / or the polyester cotton 5, an appropriate amount of powdery polymer absorber (polymer) is sprayed. As the powdery polymer absorber, those used in disposable diapers and the like can be used. As the hot melt sheet 6, a breathable fibrous material is used.

In manufacturing the inner, large contact cloths 4 and the like are laminated in the order as described above, and hot pressed with a mold having a large number of pressing frames corresponding to the contour of the inner-3. By this hot press treatment, the hot melt sheet 6 in the middle is melted, and a large number of inner-3s having the peripheral edge portions welded are manufactured.
In addition, it is usually possible to punch at the same time as the hot press, so that
A large number of finished products of Inner-3 can be manufactured in one process.

Inner-3 produced as described above
Is applied to the inside of the mask body 1 in use. When working inside the clean room, many inner
Is prepared and replaced several times a day, and only the inner-3 is discarded, and the mask body 1 is repeatedly used. During use, inhalation and exhalation pass through the inner-3, but during exhalation, moisture in the exhalation is absorbed by the hygroscopic layer of the polyester cotton 5 and urethane foam 7 (mainly the latter) and captured by the polymer absorber. . Therefore, the ions contained in the exhaled water are prevented from being extruded into the room. Of course this inner
Can be used in daily life, not only when working in the clean room.

[0012]

The present invention is as described above, and since the mask main body can be repeatedly used by exchanging only the inner, it is necessary to frequently replace the mask, such as when working in the clean room. In some cases, the economic effect is remarkable, and since the moisture in the exhaled breath is reliably absorbed in the hygroscopic layer containing the polymer absorber, it is possible to prevent the scattering of ions contained in the exhaled moisture, etc. There is an effect that it can be used for various purposes.
