Document Type and Number:
WIPO Patent Application WO/2021/251457
Kind Code:
A1
Abstract:
[Problem] Provided is a mask inner which does not increase in volume when stored, can enhance an effect of a filtering function with respect to pollen/dust and bacteria/viruses, that is an inherent objective of a mask and, can make inhalation smooth during wearing of the mask, by forming a space between the mask and a face without being bulky when stored, and by securing a wide inhalation area for external air that has passed through a filter according to inhalation. In addition, provided is a mask inner that can prevent the infiltration of air from the outside of the filter by making it difficult for a gap to be formed in an upper side and between both sides of the inner, and that can prevent leaking of breath to thereby prevent spectacles from being easily clouded. [Solution] This mask inner 10 is disposed and held inside the mask, the mask inner 10 being configured to have an opening 12 for air passage, to be able to have a substantially planar shape in a non-use state and a solid shape in a use sate, and to be able to suppress deformation of a mask toward a lower part 3 side of the nose when a wearer 1 inhales by maintaining the solid shape in a use state.
