It is formed in a cylindrical bag shape so as to cover the temporal region.

上記フードキャップ１の前部２ｂには、作業者の両目を通して目視をするための窓３が形成されている。
また、図３，図５，図６に示すように、フードキャップ１の上部２ａは、布状の外覆い部材４と網（メッシュ）状の内覆い部材５とで、内外二重構造に構成されている。上記外覆い部材４と内覆い部材５との間には収納部６が形成され、この収納部６に、作業者の頭部を保護するヘルメット７が収納される。 The front portion 2b of the hood cap 1 is formed with a window 3 for viewing through the eyes of the operator.
As shown in FIGS. 3, 5 and 6, the upper portion 2a of the hood cap 1 is constituted by a cloth-like outer covering member 4 and a mesh-like inner covering member 5 in an inner / outer double structure. Has been. A storage portion 6 is formed between the outer cover member 4 and the inner cover member 5, and a helmet 7 that protects the operator's head is stored in the storage portion 6.

また、上記外覆い部材４には、ヘルメット７を出し入れ可能な開口部９と、この開口部９を開閉するファスナー１０（開閉手段の一例）とが設けられている。尚、上記開口部９は前後方向に沿って形成されている。また、上記ヘルメット７は椀状に形成されており、庇等の外部へ突出するものは設けられていない。   Further, the outer covering member 4 is provided with an opening 9 through which the helmet 7 can be taken in and out, and a fastener 10 (an example of an opening / closing means) for opening and closing the opening 9. The opening 9 is formed along the front-rear direction. In addition, the helmet 7 is formed in a bowl shape, and there is no helmet or the like protruding outside.

また、図２，図３に示すように、フードキャップ１の後部２ｃには、頭部横周りの緩みをとる締め付け手段１２が設けられている。上記締め付け手段１２は、フードキャップ１の後部２ｃに設けられた締付帯１３と、締付帯１３の遊端部に設けられた一方の面ファスナー１４と、フードキャップ１の後部２ｃに設けられた他方の面ファスナー１５とで構成されている。尚、上記他方の面ファスナー１５は締付帯１３の基端部の左右一側方に位置しており、両方の面ファスナー１４，１５同士が離着自在になっている。   As shown in FIGS. 2 and 3, the rear portion 2 c of the hood cap 1 is provided with a fastening means 12 that takes looseness around the head. The fastening means 12 includes a fastening band 13 provided at the rear part 2c of the hood cap 1, one hook-and-loop fastener 14 provided at the free end of the fastening band 13, and the other provided at the rear part 2c of the hood cap 1.

The skirt portion 19 covers the operator's shoulder, and the lower portion is widened.

以下、上記構成における作用を説明する。
クリーンルームで作業する場合、作業者は、先ず、口をマスクで覆ったりあるいは頭部をヘアーネットで覆い、その後、図４に示すように、フードキャップ１を頭から被って、頭部および顔面を覆う。さらに、紐１６の両端１６ａを引っ張って結ぶことにより、フードキャップ１の本体部２の下部を絞る。これにより、クリーンルーム内に作業者の毛髪等が落下するのを防止し得る。 Hereinafter, the operation of the above configuration will be described.
When working in a clean room, the operator first covers the mouth with a mask or the head with a hair net, and then covers the head and face with the hood cap 1 as shown in FIG. cover. Furthermore, the lower part of the main body 2 of the hood cap 1 is squeezed by pulling and tying both ends 16 a of the string 16. Thereby, it can prevent that an operator's hair etc. fall in a clean room.

また、クリーンルームで作業上、頭部を保護する必要がある場合、作業者は、図５に示すようにファスナー１０を開け、図６に示すようにヘルメット７を開口部９からフードキャップ１の収納部６へ入れ込む。その後、図７に示すように、作業者がファスナー１０を閉じることによって、開口部９が閉じられ、ヘルメット７が収納部６に収納されるため、作業者の頭部がヘルメット７で保護される。   When it is necessary to protect the head for work in a clean room, the operator opens the fastener 10 as shown in FIG. 5, and the helmet 7 is stored in the hood cap 1 from the opening 9 as shown in FIG. Insert into part 6. Thereafter, as shown in FIG. 7, when the operator closes the fastener 10, the opening 9 is closed and the helmet 7 is stored in the storage unit 6, so that the worker's head is protected by the helmet 7. .

上記のように作業者が頭部にフードキャップ１を被って、ヘルメット７を収納部６に収納した際、上記ヘルメット７は外覆い部材４と内覆い部材５との間に挟まれて固定されるため、作業中にヘルメット７の位置がずれるのを防止することができる。   As described above, when the worker puts the hood cap 1 on the head and stores the helmet 7 in the storage portion 6, the helmet 7 is sandwiched and fixed between the outer covering member 4 and the inner covering member 5. Therefore, it is possible to prevent the position of the helmet 7 from shifting during work.

また、ヘルメット７が不要である場合、ファスナー１０を開いて、ヘルメット７を収納部６からフードキャップ１の外部へ取り外せばよい。このように、クリーンルーム内において、フードキャップ１を頭部に装着したままで、フードキャップ１に対して容易にヘルメット７を着脱することができるため、非常に利便性が良い。   When the helmet 7 is unnecessary, the fastener 10 is opened and the helmet 7 may be removed from the storage portion 6 to the outside of the hood cap 1. Thus, since the helmet 7 can be easily attached to and detached from the hood cap 1 with the hood cap 1 mounted on the head in the clean room, the convenience is very good.

また、図２に示すように、締付帯１３を他方の面ファスナー１５の方向Ａへ引っ張った状態で、一方の面ファスナー１４を他方の面ファスナー１５へ密着させることにより、フードキャップ１の頭部横周りの緩みを取ることができるため、フードキャップ１を作業者の頭部にぴったりと密着させることができる。   In addition, as shown in FIG. 2, the head of the hood cap 1 can be obtained by bringing one hook-and-loop fastener 14 into close contact with the other hook-and-loop fastener 15 in a state where the fastening band 13 is pulled in the direction A of the other hook-and-loop fastener 15. Since the looseness around the side can be removed, the hood cap 1 can be closely adhered to the operator's head.

上記実施の形態では、開閉手段の一例としてファスナー１０を用いたが、面ファスナーやボタンなどを用いて開口部９を開閉してもよい。
上記実施の形態では、開口部９を前後方向に形成しているが左右方向に形成してもよい。 In the above embodiment, the fastener 10 is used as an example of the opening / closing means. However, the opening 9 may be opened and closed using a hook-and-loop fastener or a button.
In the above embodiment, the opening 9 is formed in the front-rear direction, but it may be formed in the left-right direction.

上記実施の形態では、内覆い部材５を網（メッシュ）状に形成しているが、布状に形成してもよい。
上記実施の形態では、作業者がフードキャップ１を装着した後、ヘルメット７をフードキャップ１に取り付けているが、先にヘルメット７をフードキャップ１に取り付けておき、この状態で、作業者がフードキャップ１を装着してもよい。 In the above embodiment, the inner covering member 5 is formed in a mesh shape, but may be formed in a cloth shape.
In the above embodiment, the helmet 7 is attached to the hood cap 1 after the worker wears the hood cap 1, but the helmet 7 is first attached to the hood cap 1 in this state, The cap 1 may be attached.

上記実施の形態では、作業者は、フードキャップ１を被る前に、クリーン用のマスクやヘアーネットを装着しているが、これらマスクやヘアーネットを不要にしてもよい。また、ヘアーネットを装着した後、フードキャップ１を被り、その後、マスクを装着してもよい。   In the above embodiment, the operator wears a clean mask or hair net before wearing the hood cap 1, but the mask or hair net may be omitted. Moreover, after mounting | wearing a hair net, you may wear the food cap 1 and may mount | wear with a mask after that.

上記実施の形態では、通常、フードキャップ１を白色にしているが、フードキャップ１の上部２ａを白色以外に着色してもよい。これにより、従来のようなヘルメットを内蔵しないフードキャップと区別することができる。したがって、作業者がヘルメット内蔵型のフードキャップ１を使用していることを一目して判別することができる。   In the above embodiment, the food cap 1 is usually white, but the upper portion 2a of the food cap 1 may be colored other than white. Thereby, it can distinguish with the food cap which does not incorporate the helmet like the past. Therefore, it can be determined at a glance that the worker is using the hood cap 1 with a built-in helmet.

上記実施の形態では、図７に示すようにフードキャップ１で頭部と顔面（鼻，口）とを覆っているが、他の実施の形態として、図８に示すようにフードキャップ１の前部２ｂに開口部２１を形成し、この開口部２１から顔面（目，鼻，口）を露出させてもよい。   In the above embodiment, the head and the face (nose and mouth) are covered with the hood cap 1 as shown in FIG. 7, but as another embodiment, the front of the hood cap 1 as shown in FIG. An opening 21 may be formed in the portion 2b, and the face (eyes, nose, mouth) may be exposed from the opening 21.
