Description

  The present invention relates to a mask, and more particularly, to a mask capable of cutting off a mouthpiece sheet contaminated with a foundation or lipstick.

  Conventionally, gauze, cloth, or the like is disposed as a mouthpiece sheet on the inner surface side of the mask in order to prevent the foundation, lipstick, nasal fluid, saliva, and the like from adhering to the inner surface side of the mask and becoming dirty. For this reason, when the mouthpiece sheet becomes dirty, it is necessary to replace the mouthpiece sheet. Furthermore, the mouthpiece sheet soiled with the foundation, lipstick, runny nose, saliva, etc. needs to be washed and dried, which is a top-down use.

  In order to solve the above inconvenience, there has been proposed a mask in which the mouthpiece sheet disposed on the mask is replaceable (see Patent Documents 1 to 3). However, since these mouthpiece sheets have a planar shape, there is a problem in that when wearing a mask, the nose or mouth feels uncomfortable or tight, or easily drops off. In addition, there is a drawback that the lipstick is easily rubbed off the mouthpiece sheet arranged on the mask.

On the other hand, a mask in which a mouthpiece sheet formed into a three-dimensional shape by folding one sheet on the mask is replaceable has also been proposed (Patent Document 4). However, although this mouthpiece sheet has a three-dimensional shape, since the mask to be used is not a three-dimensional shape, there is a drawback that it does not fit in the target portion of the face including the nose and mouth.
