Description

  The present invention is a sanitary outer cap for workers used in clean rooms such as foods, cosmetics, pharmaceuticals, and semiconductors. The present invention relates to a sanitary outer cap that is comfortable, safe, and has a high dust-preventing effect without being tired even during use.

  Workers working in clean rooms such as food, cosmetics, pharmaceuticals, and semiconductors wear inner caps so that their hair, dust, etc. do not fall and contaminate the clean room, and do not contaminate products, and outer caps are placed on top of them. Wearing a double cap is common.

  In order to provide such an outer cap, in Patent Literature 1, an elastic band-shaped cloth material is used around the face so as not to release dust of the wearer, and to pull the wearer backward, in order to bring the wearer into close contact with the wearer. A dust hood with a telescopic band for contact has been proposed.

  Further, in Patent Document 2, a stretchable cloth is folded back and sewed around the open portion where the face is exposed, and a material that expands and contracts only in the forehead portion in a lateral direction is used to obtain a different face size. A working outer cap adapted to cope with the above problem is disclosed.

  The outer cap is worn on the inner cap as described above, but on the inner cap made of non-woven fabric, woven fabric, knitted fabric, etc. with unevenness and fluff, the outer fabric made of the same uneven fabric, knitted material When trying to cover the cap, a large frictional force occurs between the inner cap and the inner cap, and the inner cap and the outer cap are displaced, so that it is difficult to cover the cap at a predetermined position. As a result, there is a disadvantage that a gap is formed between the inner cap and the face, and hair and dust are spilled out.

  In addition, due to lack of air permeability due to double wearing of the inner cap and the outer cap, the operator was given a feeling of heat and stuffiness and the comfort was impaired.

  That is, in the headband of Patent Literature 1, when the outer cap is put on the inner cap, a large frictional force acts between the inner cap and the outer cap, making it difficult to put the outer cap smoothly, and creating a gap between the face and the inner cap. There is a drawback that dust and hair come out. In addition, since the adhesiveness is strong, when used for a long period of time, fatigue accumulates and impairs operator's comfort. In addition, workers feel uncomfortable due to heat due to lack of ventilation.

  In the case of Patent Literature 2, it is difficult to cover the inner cap without slippage due to a large friction between the inner cap and the inner cap fabric because the fabric does not extend in the side portion. For this reason, there is a drawback that a gap is formed between the face and the inner cap, and hair and dust leak out. In addition, since the outer cap has high adhesion of the forehead, it has a poor feeling of comfort and gives a worker uncomfortable feeling when worn for a long time. Furthermore, there is little consideration for ventilation, and workers feel discomfort in the heat.

  In the case of Patent Literatures 1 and 2, a hood-shaped cap is formed by sewing some fabric parts according to the wear site, etc., but the number of parts is relatively small, 3 to 5, and the flexibility of adjustment is high. There is also a problem that lacks.

  The present invention has been made in order to solve the above-mentioned problem, and an object of the present invention is to be able to smoothly cover over an inner cap and to fit without forming a gap between a face and a cap. And to provide a comfortable and safe sanitary outer cap without stuffiness.

  In order to achieve the above-mentioned object, in the present invention, a hood-shaped cap body having an opening for exposing the face is provided while covering from the head to the neck, and an inner cap for covering the hair is previously worn. A sanitary outer cap to which a head is inserted by being inserted from the neck side of the cap main body, wherein a portion adjacent to the opening portion is covered with a head surrounding covering portion, and both ends of the head surrounding covering portion are covered with the both ends. A means is used which comprises a face surrounding covering portion which is connected to cover the front side of the neck from both sides of the face, and at least one of the head surrounding covering portion and the face surrounding covering portion is constituted by an elastic cloth. This stretchable cloth preferably has a tensile elongation to break of 100% or more, a tensile stress at 25% tensile elongation of 1 N / cm or less, and an elongation modulus of 90% or more. This is because, due to the good elongation, the state can be greatly expanded at the time of mounting, and the chance of contact with the inner cap can be reduced.

  According to such a configuration, when the sanitary outer cap is attached, the head surrounding covering portion or the face surrounding covering portion has an appropriate characteristic, and the elastic cloth with the appropriate characteristics reduces friction with the inner cap and realizes smooth covering.

  It is preferable that the head surrounding covering portion and the face surrounding covering portion are made of the same elastic cloth. This is because the range in which the friction with the inner cap is reduced is expanded, and smoother wearing becomes possible.

  For the opening portion, a means is used in which a strong elastic cloth is used in which two or more elastic cloths, which are the same as the head surrounding covering part or the face surrounding covering part, are stacked so as to be able to adhere to the face. According to such a means, the highly stretchable cloth constituting the opening portion has an excellent stretch recovery property, so that it fits the face without creating a gap between the face and the face. Therefore, hair and dust do not leak outside.

  In addition, it is preferable that an opening part consists of two members, the horizontal band part along a forehead, and the U-shaped band part along a temple from a lower jaw, and it is preferable to comprise each with the same strong elastic cloth. This is because the feeling of fitting to the face is improved as compared with the case where it is formed by one member.

Other covering parts except for the opening part, the head circumference covering part, and the face surrounding covering part in the cap body have an air permeability of 70 cm ³ / cm ² · s or more, and have a tensile elongation to breakage of an elastic cloth. A means of using a smaller air permeable cloth is used. According to this means, the other covering portion has high air permeability, but is made of a cloth with little elongation, so that it does not adhere to the head and creates a wide space between the cap body and the head, and has a large air flow. Due to the nature, heat and moisture do not stay in the cap and do not cause discomfort to the operator. This also gives a smooth fogging effect when fogging.

  The other covering part is preferably composed of two members, a top covering part arranged above the head circumference covering part and an occipital covering part arranged behind the face surrounding covering part. This is because a three-dimensional shape can be obtained rather than a single member, and the above-described air permeability and a smooth covering effect can be reliably obtained.

  In addition, it is preferable that a cap portion that covers both shoulders is further provided on a lower edge of the cap body. By inserting this cape portion inside the work clothes, it is possible to more reliably prevent hair and dust from scattering.

  Furthermore, it is preferable that elastic short bands are attached to both upper corners of the opening, and a slit that can be inserted into the hood with the vine of the glasses sandwiched between the elastic short band and the cap body is preferable. . This is in consideration of the convenience of the spectacle wearer.

  In the sanitary outer cap according to the present invention having the above-described configuration, since the head-surrounding covering portion or the face surrounding covering portion provided adjacent to the opening portion is made of a stretchable cloth, when this is mounted on the inner cap, In addition, it has a suitable elongation, tensile force, elongation modulus, and dynamic frictional force reduction effect, and exhibits smooth coverability. In addition, since the two members of the horizontal band and the U-shaped band forming the opening are made of a highly elastic cloth, there is a feeling of fitting to the face, and there is no gap between the face and the sanitary outer cap. It was possible to prevent contaminants such as dust, hair and dust from leaking to the outside.

  In addition, a large space is created by using a cloth with large air permeability and low elongation in the top cover part and the occipital cover part, exhausting the internal air current containing water vapor whose temperature has risen to suppress the rise in internal temperature for a long time. A comfortable environment was provided throughout.
