Title: Face mask
Inventor: SHIRATAKE TAKUMA
IPC: A41D13/11
Filed: 2018-02-01
Abstract: To provide a face mask excellent in mountability.SOLUTION: In a face mask, an ear hooking member comprises a first opening and a second opening located away from a mask body relative to the first opening. Since an effective length of the ear hooking member can be lengthened by cutting an area between the first opening and the second opening (intervening area) to link the first opening and the second opening together, and also the ear hooking member has stretchability, the mask can be easily worn and a trouble that a function of mask is not sufficiently performed due to a poor wearing property is prevented. Further, since the ear hooking member has an elongation lower in the direction perpendicular to the direction away from the mask body than in a direction away from the mask body, an unintended breakage is unlikely to occur in the intervening area of the ear hooking member during wearing and an unintended linkage between the first opening and the second opening can be prevented.SELECTED DRAWING: Figure 3
