[0002]
[Prior art]
In the manufacturing process of chemicals , contamination of foreign substances into hygienic products has become a major problem. For this reason, various considerations such as wearing dust-proof clothing and dust-proof hood have been made in chemical manufacturing operations. In particular, during work, the eyelashes and eyebrows of the operator fall off, fall off from the opening on the hood face, and use goggles that cover the eyes to deal with problems that mix with the product. ing.
[0003]
However, the goggles are uncomfortable because the wearer's head is tightened by the belt for wearing the goggles and is not suitable for long-time use. In addition, after use, it was a dust-proof measure not particularly welcomed by women, such as the appearance of goggles on the face due to pressure when worn.
[0004]
[Problems of the Invention]
Therefore, the subject of this invention is preventing fall of eyelashes etc. from the opening part by the side of the face of a dustproof hood.
[0005]
[Means for Solving the Invention]
Therefore, the present invention provides a dust-proof hood comprising a hood body that wraps the head and a skirt portion that covers the neck to the shoulder at the lower part of the hood body, and covers the eye opening of the hood body with a transparent film, The position leading to the mouth is covered with a breathable material attached to the hood body. The transparent film is detachable from the hood body, and the lower part of the transparent film is connected to a breathable material that covers a position from the nose to the mouth. The breathable material is composed of an outer cloth and an inner cloth, and the lower part of the transparent film is inserted into an upper opening type pocket formed by the outer cloth and the inner cloth (Claims 1 and 2). .
[0006]
The hood body has a collar at the upper part of the opening, and the upper part of the transparent film is detachably connected to the collar (Claim 1). Further, the breathable material is attached to the hood main body by a detachable tool in a separable state (claim 2).
[0007]
DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show a dustproof hood 1 of the present invention. The dustproof hood 1 is constituted by a hood body 2 that wraps the head. The hood body 2 is a cloth having a high weaving density, for example, containing a flexible conductive thread, so as to wrap the operator's head, and forms an opening 3 at a position corresponding to the eyes at the position of the operator's face. ing. The position from the nose to the mouth below the opening 3 of the hood main body 2 is cut out, and the cut-out portion is closed by a breathable material 5 sewn on the hood main body 2 along the periphery of the cut-out portion. It is peeling off.
[0008]
The breathable material 5 is made of breathable fibers such as non-woven fabric or mesh-like fibers that are large enough to prevent the passage of dust and facilitate the breathing of the wearer. And an outer cloth 6 that is sewn only at the lower and left and right portions with respect to the hood body 2 and is sewn in the left-right direction at an intermediate position with respect to the inner cloth 7. Has been. As a result, the outer cloth 6 and the inner cloth 7 form an upper opening type pocket above the intermediate height.
[0009]
The opening 3 is covered with a transparent film 4. That is, the transparent film 4 is detachably attached to the collar 10 formed on the upper portion of the opening 3 by a fixing tool 8 such as a snap button, and to the lower edge of the opening 3 by the right and left fixing tools 9, respectively. Is attached. As a result, the lower part of the transparent film 4 is inserted into an upper opening type pocket between the outer cloth 6 and the inner cloth 7 as the breathable material 5 and is detachable from the hood body 2. The internal space of the transparent film 4 is a storage space for spectacles, and also secures an appropriate amount of air for anti-fogging.
[0010]
In this embodiment, the hood body 2 is composed of a combination of a plurality of three-dimensional cut cloths at the portion covering the face, and a combination of a cloth covering the back side of the head and a cloth covering the top surface of the head. ing. And in order to adjust the head periphery, the belt 13 and the adjustment tool 11 for adjusting this belt length are provided in the rear part. A skirt portion 12 is sewn on the lower portion of the hood main body 2 to cover the shoulder portion from the neck of the operator.
[0011]
According to the dustproof hood 1 configured as described above, the opening 3 at the position of the operator's eyes is covered with the transparent film 4, so that the peeled material from the human body such as eyelashes is protected against dust while ensuring the worker's field of view. It does not scatter from the inside to the outside, thereby preventing foreign matters from entering the product. When the operator's eyelashes or the like fall from the human body with the dust hood 1 worn, it is guided to the inner surface of the transparent film 4 and stored in the pocket-shaped portion between the inner cloth 7 and the outer cloth 6. It is held in this part and will not be scattered outside. Moreover, since the breathable material 5 (outer cloth 6 and inner cloth 7) such as mesh fiber or non-woven fabric is sewn on the lower part of the transparent film 4, that is, the part corresponding to the nose and mouth of the worker, Because of its breathability, you can work in an easy breathing state.
[0012]
And since the transparent film 4 is fixed by the upper part and pressed down as the state pinched | interposed by the outer cloth 6 and the inner cloth 7 in the lower part, it is in the state which does not give a wearer a feeling of clamping. In addition, when the operator moves the head, the transparent film 4 is allowed to move by sliding the lower part of the transparent film 4 vertically to the air-permeable material 5 (the outer cloth 6 and the inner cloth 7). Therefore, the rigidity of the transparent film 4 does not hinder the movement.
[0013]
Transparency film 4, it is possible to easily attached to and detached from the hood main body 2, when the sterilizing hood body 2, can be processed to remove the portion of the weak transparent film 4 to the heat. When the transparent film 4 is damaged, the hood main body 2 can be used continuously by replacing only the transparent film 4, which is economical for the user. In particular, if the breathable material 5 is made of a mesh material, breathing is efficiently discharged and inhaled, so that the inside of the dust-proof hood 1 can be prevented and fogging of the transparent film 4 is reduced.
[0014]
In addition, when the collar 10 is formed in the upper part of the opening part 3, since the light from the upper part does not enter into the inside of the transparent film 4, the irregular reflection in the inner surface of the transparent film 4 can be prevented, and an operator's visual field improves. .
[0015]
Next, the example of FIG. 3 is an example in which the breathable material 5 is a separate member with respect to the hood main body 2 and is attached to the hood main body 2 in a state where it can be separated by the left and right attachments 14 such as Velcro tape. In this case, the transparent film 4 is inserted into a pocket of the upper opening type between the outer cloth 6 and the inner cloth 7 as the permeable material 5 at the lower part, and is attached to the inner cloth 7 of the breathable material 5 by the fixture 9. If necessary, it is attached to the hood main body 2 by the fixing tool 8 at the upper part. Here, the lower edge of the breathable material 5 is integrated with a cloth 15 for covering the neck portion. A rubber string 16 is passed through the left and right ends of the cloth 15, and a string 17 for passing the cloth 15 under the chin is passed through the lower side through-hole.
[0016]
The dust-proof hood 1 can be used inside a so-called clean room in the manufacturing process of precision machinery and semiconductor products, in addition to operations for manufacturing chemicals and the like.
[0017]
【The invention's effect】
In the present invention, the following specific effects can be obtained. Since the opening at the eye position of the hood main body is covered with a transparent film in a dust-proof hood wearing state, scattering of eyelashes and the like from the opening can be prevented, and foreign matters can be prevented from being mixed into the product. In particular, even if the operator's (wearer's) eyelashes fall, they are guided by the inner surface of the transparent film and stored in a pocket-shaped part formed between the inner and outer fabrics as a breathable material. Finally, it is held in this portion and does not scatter outside (Claims 1 and 2).
[0018]
Moreover, the position from the nose to the mouth of the worker is covered with a breathable material (inner cloth / outer cloth), and the breathability can be secured at that position, so that the worker can breathe easily and the inside of the transparent film The work can be carried out in a comfortable state without being clouded or peeled off (claims 1 and 2).
[0019]
The transparent film covers the opening of the hood body, is connected at the pocket-shaped part between the outer cloth and inner cloth as a breathable material, is held only at the front part of the hood body, and is detachable Since it is combined, the work can be performed in a comfortable state without giving the wearer a feeling of tightening. When the hood body is sterilized, it can be removed by removing the transparent film that is vulnerable to heat. Further, when the transparent film portion is damaged, the hood main body portion can continue to be used by exchanging only the transparent film, which is economical for the user (claims 1 and 2).
[0020]
When the work skilled moves the head by a certain degree slide up and down direction in the pocket-shaped portion between the lower portion of the transparent film and the outer fabric and the inner fabric as breathable material, in order to permit the movement of the transparent film In addition, the rigidity of the transparent film does not hinder the movement of the worker (claims 1 and 2).
[0021]
In addition, a collar is provided on the hood body, which covers the upper part of the transparent film and is detachable from the upper part of the transparent film. Therefore, there is no glare due to irregular reflection, and visibility is improved.
[0022]
In an example in which a breathable material (inner cloth / outer cloth) is attached to the hood main body as a separate member with respect to the hood main body, the breathable material (inner cloth / outer cloth) that is easily soiled can be separated from the hood main body. Therefore, it is convenient (claim 2). Further, the presence of the cloth on the lower edge of the breathable material can cover the neck part, and the cloth can be applied to the chin part by tightening the string (claim 2) .
