Description

本発明は、粉塵、細菌又はウイルス等が顔や頭に付着すること及び飛沫感染することを防止するためのヘッドカバーに関する。 The present invention relates to a head cover for preventing dust, bacteria, viruses, etc. from adhering to the face or head and being infected by droplets.

使用者が、皮膚または頭皮を通じて危険物質を吸収することを防止するためのヘッドカバーとしては、特許文献１（特表２００５−５１２６４１号公報）に記載されているように、織物等の材料から作製されるフード付のカバーであり、透明保護視野窓を備えるもの等が知られている（特に、段落００１５〜００１６及び図１、図２を参照）。
また、粉塵、細菌又はウイルスの付着を防止するものではないが、防煙を目的としたヘッドカバーであって、小さく折り畳んで持ち運べる布、紙又は透明シート製のものが、特許文献２（実開昭６４−１７２５９号公報、特に、明細書第４頁第１４行〜第６頁末行及び第１〜３図を参照）や特許文献３（実開昭５１−１１８３２０号公報、特に、明細書第２頁第１行〜第３頁第３行及び第１〜３図を参照）に記載されている。 As a head cover for preventing the user from absorbing dangerous substances through the skin or scalp, as described in Patent Document 1 (Japanese Patent Laid-Open No. 2005-512461), it is made of a material such as a woven fabric. A cover with a hood and a transparent protective viewing window is known (see in particular, paragraphs 0015 to 0016 and FIGS. 1 and 2).
Further, although it does not prevent the adhesion of dust, bacteria or viruses, a head cover for the purpose of smoke prevention, which is made of cloth, paper or a transparent sheet that can be folded into a small size and carried, is Patent Document 2 (Actual Kaisho). 64-127259, in particular, see page 4, lines 14 to 6, end lines and FIGS. 1 to 3 of the specification) and Patent Document 3 (Jikkai Sho 51-118320, in particular, specification No. 51-118320). It is described in page 2, line 1 to page 3, line 3, and FIGS. 1 to 3).

ところが、特許文献１記載のヘッドカバーは、図１、２の記載から分かるように、使用者の頭部にぴったりと装着されるため、漏れに対して最大の保護を提供できるが（段落００１６の第１３〜１５行参照）、装着に時間を要し、繊維材料等で作製されているため、コストが高く、折り畳めてもかさばるという問題があった。
また、特許文献２及び３記載の防煙用ヘッドカバーは、小さく折り畳むことはできるものの、利用時の形状が円筒状又は直方体状で頭にフィットしにくいため、短時間使用する場合は良いが、長時間使用する場合には装着感が悪く作業性が良くないという問題があった。 However, as can be seen from the descriptions in FIGS. 1 and 2, the head cover described in Patent Document 1 is fitted to the user's head so as to provide maximum protection against leakage (paragraph 0016, paragraph 0016). (Refer to lines 13 to 15), it takes a long time to attach, and since it is made of a fiber material or the like, there is a problem that the cost is high and it is bulky even when folded.
Further, although the smoke-proof head cover described in Patent Documents 2 and 3 can be folded into a small size, the shape at the time of use is cylindrical or rectangular parallelepiped and it is difficult to fit the head. When used for a long time, there is a problem that the wearing feeling is poor and the workability is not good.
