PROBLEM TO BE SOLVED: To close a mouth during sleep and mask use time, for preventing onset of various diseases, and facilitate temporary mouth breathing or conversation.SOLUTION: A mouth closing tape is configured so that: an adhesive mass is adhered thereto an O-shape is overlapped to a center of a lateral X-shape and an opening part (6) is formed on a center part. When a user performs temporary mouth breathing such as yawn, or converses, in a state in which X-shape end parts (4) obliquely projecting, and O-shape vertical parts (5) are fixed, the tape moves vertically, similar to a parallel link mechanism which is vertically lifted up and down, so that a user can move his/her lips. When a user releases tension from his/her mouth, a mouth is closed by shrinkage of a tape material. In addition, even when a mouth of a user is fully opened and a load equal to or higher than limitation level is applied to the tape material, the tape snaps apart and a shape is changed, so that the tape is not peeled. The tape is connected to inside of a mask having flexibility, for using as a mouth closing mask.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】さまざまな病気を防止するため、睡眠時やマスク使用時に口を閉じる一方で、一時的な口呼吸や会話は行い易くする。【解決手段】口閉じテープは、粘着剤が塗布され、横長のX字型の中央に、O字型を重ねた形状であり、中央に開口部(6)がある。一時的にあくびなどの口呼吸をしたり、会話をしたりする場合には、斜めに出たX字型端部(4)と、上下のO字型上下部(5)が固定されたまま、上下に昇降する並行リンク機構に類似して縦長に動き、唇を動かすことができる。口の力を抜くと、テープ素材の収縮で口が閉じられる。さらに、口を大きく空けてテープ素材に限界以上の負荷がかかる場合でも断裂して形状が変化することで剥がれない。また、収縮性のあるマスクの内側にテープを接続して口閉じマスクとして使うこともできる。【選択図】図1
