Abstract
A face mask for improved fluid resistance is provided. The face mask may include a body portion with a first layer and a second layer. The first and second layers may have a plurality of folds that form a plurality of first creases in the first layer and a plurality of second creases in the second layer. The body portion may have an outer facing surface and an inner facing surface opposite from the outer facing surface. At least one of the first creases may be misaligned with at least one of the second creases in order to provide improved fluid resistance of the body portion.
Claims14
A face mask, comprising:
- a body portion configured to be placed over a mouth and at least part of a nose of a user in order to isolate the mouth and the at least part of the nose of the user from the environment,
- wherein said body portion has a first layer with a plurality of folds forming a plurality of first creases and wherein said folds extend across the entire horizontal length of said first layer and are configured to unfold in order to extend the length of said first layer in the vertical direction, said folds in said first layer pointed in a first direction relative to said body portion,
- wherein said body portion has a second layer adjacent with said first layer and has a plurality of folds forming a plurality of second creases wherein said folds extend across the entire horizontal length of said second layer and are configured to unfold in order to extend the length of said second layer in the vertical direction, said folds in said second layer pointed in the same first direction as said folds in said first layer so as to unfold in the same direction as said folds in said first layer,
- wherein said first creases of said plurality of folds in said first layer are misaligned and unnested with said second creases of said plurality of folds in said second layer.
A face mask, comprising:
- a body portion with a first layer and a second layer wherein said first and said second layers have a plurality of folds pointed in the same direction relative to said body portion and forming a plurality of first creases in said first layer and a plurality of second creases in said second layer, said body portion having an outer facing surface and an inner facing surface opposite from said outer facing surface, and wherein at least one of said first creases is misaligned and unnested with at least one of said second creases.
