A mask part 6 for covering a nose and a mouth at a lower part of an opening part 4 for eyes, comprises a bellows cloth 8 for covering the periphery of a chin, a pad part to be closely kept into contact with the nose and the left and right cheeks, and a gore 20 for connecting the pad part 9 and the mask part 6. Further the pad part 9 has a shape to be closely kept into contact with the difference in level part between the nose and the left and right cheeks, and is wrapped by the cloth of the gore 10. The pad part 9 is closely kept into contact with a face from the nose to the left and right cheeks, when an workman wears the dustproof hood, so that the space can not be found in the difference in level part between the nose and the left and right cheeks.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dustproof hood used in a clean space such as a clean room, and to a means for sealing a step between a nose and left and right cheeks.

[0002]

2. Description of the Related Art In a process of manufacturing electronic components in a clean room and a process of manufacturing chemicals in a clean space, a dust hood is used to prevent dust from being emitted from a human body. Most dust-proof hoods are designed to cover the head, but a part of the face, especially the eyes, is open to secure the view, and the lower part of the opening is a nose. And a mask portion for covering the mouth.

In such a dust hood, the mask is in contact with the nose and the left and right cheeks. At the time of this wearing, the step between the nose and the left and right cheeks is open,
Dust generated from the human body is likely to flow out of that part.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to prevent dust from flowing out of a step between a nose and left and right cheeks.

[0005]

According to the present invention, there is provided a dustproof hood used in a clean space such as a clean room, wherein the soft pad is formed by a flexible member so as to fill a step between a nose and left and right cheeks. The portion is arranged at a position below the opening for opening of the hood portion, and a flexible town connected to the pad portion is connected to the upper portion of the mask portion of the hood portion. Here, the mask portion is integrated with the hood portion by sewing or is combined in a separable state.

[0006]

1, 2 and 3 show a dustproof hood 1 according to the present invention. The dustproof hood 1 is sewn to a hood 2 surrounding the head, and a lower portion of the hood 2.
It is constituted by a skirt portion 3 that covers a portion from the neck to the shoulder. The hood section 2 is used to wrap the head of the worker,
For example, it is made of a cloth having a high weaving density with a soft conductive yarn, and at the face position of the operator, an opening 4 for displaying eyes is formed, and at a portion corresponding to the left and right ears,
The ears 5 made of a mesh cloth are integrally formed.

A portion from the nose to the mouth below the opening 4 serves as a mask 6 for covering the nose and the mouth. In this embodiment, the mask section 6 includes a cloth 7 covering the left and right cheeks from the nose, a bellows-shaped cloth 8 covering the periphery of the chin below the cloth 7, and a pad section 9 closely contacting the nose and the left and right cheeks. And a town 10 for connecting the pad section 9 and the mask section 6.

The cloths 7 and 8 are draped so as to surround the chin from below the face. Further, the pad portion 9 is formed of a flexible sponge-like member so as to be in close contact with the step of the nose and the left and right cheeks, and is wrapped by the cloth of the town 10. The town 10 is in a sufficiently bent state, and
Is sewn to a cloth 7, for example.

In this embodiment, the mask portion 6 is sewn along the contour to the front surface of the hood portion 2 and integrated. In addition, the inside of the mask part 6 is provided so that the address cloth 11 such as a mesh cloth can be easily attached and detached as necessary. Further, tightening cords 12 are sewn on the left and right sides of the hood portion 2.

Here, if the pad portion 9 is too large, it obstructs the view below the wearer, so that the pad portion 9 is configured to be the minimum necessary. The pad portion 9 is formed by the town 10 along the face of the wearer. It is provided so that it may adhere. In this case, since the town 10 is provided to extend downward, it does not protrude upward and does not obstruct the view below.

The skirt portion 3 is formed in a skirt shape by a cloth having a high weaving density with a soft conductive yarn, and is sewn under the hood portion 2 at an upper portion, similarly to the hood portion 2. I have.

When the worker wears the dustproof hood 1 having the above configuration, the pad portion 9 adheres closely from the nose to the left and right cheeks, so that no space is formed at the step between the nose and the left and right cheeks. . Therefore, it is possible to prevent dust from leaking from the step portion. The pad portion 9 is formed along the nose and the left and right cheek surfaces. If necessary, a deformable material such as a thin wire is embedded in the inside of the pad portion 9 so that the left and right cheeks are inserted from the wearer's nose. You may make it deform | transform into the shape which follows a cheek surface, and may maintain the deformed state. By doing so, the degree of adhesion of the pad portion 9 to the face is further ensured.

Next, a specific example of FIG. 4 is an example in which the flat band-shaped pad portion 9 is folded inward while twisting left and right, and both end portions thereof are sewn to the inner surface of the cloth 7. In this way, the pad section 9 is in a form in which the pad section 9 comes into close contact with the wearer's nose and the left and right cheeks without inserting a core material.

Further, in the specific example of FIG. 5, the mask portion 6 is not sewn to the hood portion 2 but is separable, and the left and right rubber strings (not shown), non-stretchable strings, or magic tape (not shown) are used. This is an example in which it is detachably attached to the hood section 2 by a registered trademark or the like. In the case of this embodiment, the mask portion 6 is advantageous in that it can be washed frequently according to dirt separately from the hood portion 2 and the skirt portion 3.

[0015]

According to the present invention, since the pad portion attached to the mask portion is in close contact with the wearer's nose and left and right cheeks, no space is formed in the steps, and dust from inside is not formed. It can be prevented before it happens. In addition, the pad part is connected to the mask part by the town, and it is in a state where it can be displaced according to the shape of the wearer's nose and cheek, and the town allows the movement, so that the wearer's view is not obstructed Can respond flexibly to changes in the face.
