［図８］図８は、一対のフラップＦ（３組合計６個）を持ち上げて開口部（３組合計６個）を形成した本発明に係る立体形状の衛生マスク１００（実施例１）を表す側面図である。図８には、一対の切込み線ＣＬ（３組合計６個）、一対のフラップＦ（３組合計６個）、一対の第３の山折り線Ｌ３（３組合計６個）が表されている。
［図９］図９は、本発明に係る平面形状の衛生マスク１００を折り畳んで、収納する状態を表すである。立体形状の衛生マスク２００は、口ばしＫを設けた先頭部Ｂ０を切込み線ＣＬから抜く等、平面形状の衛生マスク１００を立体形状にした逆の工程を採れば、立体形状の衛生マスク２００を平面形状の衛生マスク１００にすることができ、さらに、山折り線Ｌ１、一対の第３の山折り線を図９のように山折りすれば、コンパクトに収納できる。
［図１０］図１０は、本発明に係る平面形状の衛生マスク１００（フラップＦを閉じた状態）の使用状態を表す図面である。
［図１１］図１１は、本発明に係る平面形状の衛生マスク１００（フラップＦを開いた状態）の使用状態を表す図面である。
［図１２］図１２は、請求項６に記載された「切欠き円ｃが設けられてなること」を説明する図面である。
図１２の（Ａ）図は、一対の切込み線ＣＬの両端部に、切欠き円ｃが設けられてなることを表す平面面である。切欠き円ｃは、その周辺を切込み線ＣＬで囲まれてなり、首部を介してマスク本体９９と繋がっている。フラップ切込み線ＣＬ２、第２の山折り線Ｌ２の両端部にも、同様の切欠き円ｃが設けられている。図１２の（Ｂ）図は、一対の切込み線ＣＬの両端部に、貫通穴ｈが設けられてなることを表す平面面である。貫通穴ｈは、切欠き円ｃを、首部を切断して取り除くことにより、形成されたものである。図１２の（Ａ）図の切欠き円ｃは、首部を切断して取り除くことにより、図１２の（Ｂ）図の貫通穴ｈとなるので、図１２の（Ａ）図の切欠き円ｃと図１２の（Ｂ）図の貫通穴ｈは、同義である。
［図１３］図１３は、「ベルトＢ先頭部Ｂ０を切込み線ＣＬに差し込んで、口ばしＫを設けた先頭部Ｂ０が嵌合係止すること」を説明するための平面図である。切込み線ＣＬの両端に設けた切欠き円ｃはないものとする。このように設定しても一般性は失われない。ベルトＢの先頭部Ｂ０を、切込み線ＣＬに差し込めば、点Ｋ１と点Ｃ１は一致する。ベルトＢの先頭部Ｂ０には、復元力Ｐ（ｋｇ重）が残存し、復元力Ｐ（ｋｇ重）は、ベルトＢの先頭部Ｂ０の口ばしＫの点Ｋ１に作用する。点Ｋ１と点Ｃ１の両点間には作用反作用の法則が成立する。すると、復元力Ｐ（ｋｇ重）の反力が、マスク本体９９の点Ｃ１に作用する。そして、点Ｋ１と点Ｃ１は一致することから、復元力Ｐ（ｋｇ重）と復元力Ｐ（ｋｇ重）の反力は釣り合うことになり、立体形状の衛生マスク２００の立体形状は保持され、平面形状の衛生マスク１００に戻ろうとすることが妨げられる。

以下、本発明に係る平面形状の衛生マスク１００について、図面を参照しながら説明する。

There is. 図９は、本発明に係る平面形状の衛生マスク１００を折り畳んで、収納する状態を表すである。立体形状の衛生マスク２００は、口ばしＫを設けた先頭部Ｂ０を切込み線ＣＬから抜く等、平面形状の衛生マスク１００を立体形状にした逆の工程を採れば、立体形状の衛生マスク２００を平面形状の衛生マスク１００にすることができ、さらに、山折り線Ｌ１、一対の第３の山折り線を図９のように山折りすれば、コンパクトに収納できる。FIG. 9 shows a state in which the flat sanitary mask 100 according to the present invention is folded and stored. The three-dimensional sanitary mask 200 can be obtained by taking the reverse process of making the flat sanitary mask 100 into a three-dimensional shape, such as pulling out the head portion B0 provided with the mouthpiece K from the cut line CL. Can be made into a flat sanitary mask 100, and further, if the mountain fold line L1 and the pair of third mountain fold lines are mountain-folded as shown in FIG. 9, they can be stored compactly. 図１０は、本発明に係る平面形状の衛生マスク１００（フラップＦを閉じた状態）の使用状態を表す図面である。FIG. 10 is a drawing showing a usage state of the flat sanitary mask 100 (state in which the flap F is closed) according to the present invention. 図１１は、本発明に係る平面形状の衛生マスク１００（フラップＦを開いた状態）の使用状態を表す図面である。FIG. 11 is a drawing showing a usage state of the flat sanitary mask 100 (in a state where the flap F is opened) according to the present invention. 図１２は、請求項６に記載された「切欠き円ｃが設けられてなること」を説明する図面である。図１２の（Ａ）図は、一対の切込み線ＣＬの両端部に、切欠き円ｃが設けられてなることを表す平面面である。切欠き円ｃは、その周辺を切込み線ＣＬで囲まれてなり、首部を介してマスク本体９９と繋がっている。フラップ切込み線ＣＬ２、第２の山折り線Ｌ２の両端部にも、同様の切欠き円ｃが設けられている。図１２の（Ｂ）図は、一対の切込み線ＣＬの両端部に、貫通穴ｈが設けられてなることを表す平面面である。貫通穴ｈは、切欠き円ｃを、首部を切断して取り除くことにより、形成されたものである。図１２の（Ａ）図の切欠き円ｃは、首部を切断して取り除くことにより、図１２の（Ｂ）図の貫通穴ｈとなるので、図１２の（Ａ）図の切欠き円ｃと図１２の（Ｂ）図の貫通穴ｈは、同義である。FIG. 12 is a drawing for explaining "the notch circle c is provided" according to claim 6. FIG. 12A is a plane surface showing that notch circles c are provided at both ends of the pair of cut lines CL. The notch circle c is surrounded by a notch line CL, and is connected to the mask main body 99 via the neck portion. Similar notch circles c are provided at both ends of the flap notch line CL2 and the second mountain fold line L2. FIG. 12B is a plane surface showing that through holes h are provided at both ends of the pair of cut lines CL. The through hole h is formed by removing the notch circle c by cutting the neck portion. The notch circle c in FIG. 12 (A) becomes the through hole h in FIG. 12 (B) by cutting and removing the neck portion, so that the notch circle c in FIG. 12 (A) is formed. And the through hole h in FIG. 12B are synonymous with each other. 図１３は、「ベルトＢ先頭部Ｂ０を切込み線ＣＬに差し込んで、切込み線ＣＬと口ばしＫを設けた先頭部Ｂ０が嵌合係止すること」を説明するための平面図である。切込み線ＣＬの両端に設けた切欠き円ｃはないものとする。このように設定しても一般性は失われない。ベルトＢの先頭部Ｂ０を、切込み線ＣＬに差し込めば、点Ｋ１と点Ｃ１は一致する。ベルトＢの先頭部Ｂ０には、復元力Ｐ（ｋｇ重）が残存し、復元力Ｐ（ｋｇ重）は、ベルトＢの先頭部Ｂ０の口ばしＫの点Ｋ１に作用する。点Ｋ１と点Ｃ１の両点間には作用反作用の法則が成立する。すると、復元力Ｐ（ｋｇ重）の反力が、マスク本体９９の点Ｃ１に作用する。そして、点Ｋ１と点Ｃ１は一致することから、復元力Ｐ（ｋｇ重）と復元力Ｐ（ｋｇ重）の反力は釣り合うことになり、立体形状の衛生マスク２００の立体形状は保持され、平面形状の衛生マスク１００に戻ろうとすることが妨げられる。FIG. 13 is a plan view for explaining "the belt B head portion B0 is inserted into the cut line CL, and the cut line CL and the head portion B0 provided with the beak K are fitted and locked". It is assumed that there are no notch circles c provided at both ends of the notch line CL. Even with this setting, generality is not lost. If the leading portion B0 of the belt B is inserted into the cut line CL, the points K1 and C1 coincide with each other. The restoring force P (kg weight) remains at the head portion B0 of the belt B, and the restoring force P (kg weight) acts on the point K1 of the beak K of the head portion B0 of the belt B. The law of action and reaction holds between both points K1 and C1. Then, the reaction force of the restoring force P (kg weight) acts on the point C1 of the mask body 99. Since the points K1 and C1 coincide with each other, the reaction forces of the restoring force P (kg weight) and the restoring force P (kg weight) are balanced, and the three-dimensional shape of the three-dimensional sanitary mask 200 is maintained. Attempts to return to the planar sanitary mask 100 are prevented.
