A mask sheet is provided. The mask sheet is a mesh sheet in which twisted yarns are knitted into a mesh shape, the twisted yarns being provided by twisting filaments each of which is formed by coating a synthetic fiber with silver. A stitch opening of the mesh sheet may be 1 mm or more. The mesh sheet may be a tricot-knitted sheet.

Described is a double-protection medical mask (1, 101), preferably for filtering dust, smog, aerosol, pathogenic agents, viruses and the like, which comprises a portion (2, 102) covering at least of the area of the nose, mouth and chin, provided with filtration means and designed to be hermetically and removably fixed to the face of the user (9) by adhesion means.

This present invention relates to a modified face mask that helps to reduce the spread of airborne pathogens while allowing the wearer to eat and drink without removing their mask. The dual-layer face mask features an internal frame and a middle hinge that allows a user to pull one layer of the mask outwards in a diamond-like shape to create space under the mask, enables the user to insert an eating utensil or straw into their mouth while consuming food or beverages. In this manner, the face mask of the present invention improves the safety of the users and prevents the spread of infectious diseases.

A face mask includes a body, two cords, and a retaining bead having a cord constraining passage. The body has upper and lower body edges spaced apart from one another by opposed left and right body edges. The body has left and right cord channels along the left and right body edges, respectively. Each cord extends from a first end, through a corresponding one of the left and right cord channels, to a second end. Each cord has first and second segments proximate the first and second ends, respectively. The first and second segments of each cord pass through the cord constraining passage. The cord constraining passage is sized to frictionally engage the first and second segments of each cord such that the retaining bead holds its position. The retaining bead is slidable along the first and second segments of each cord to advance the retaining bead toward the body.

A facial covering is formed from a single sheet of material. The facial covering comprises a facial coverage region for covering part of a face of a wearer and two lateral regions for holding the facial coverage region in place on the wearer. Each lateral region comprises an ear retainer and an extending section. The extending section comprises a plurality of slits disposed such that the extending section is capable of elastic extension between the ear retainer and the facial coverage region. Methods of manufacturing and of assembling such a facial covering are also described.

A face covering comprises a first part and a second part. The second part is attached to the first part along a border, the border extending from a) a nose region, corresponding to a nose of an individual when the face covering is worn by the individual, to b) a chin region, corresponding to a chin of the individual when the face covering is worn by the individual. The first part and the second part are separable along the border.

A face mask face mask is configured to be worn on a human head and includes a face shield and at least one mounting strap. The face shield includes a multi-layer body portion comprising an outer layer, a middle layer and an inner layer. The outer layer is provided by a stitched fabric spacer, the middle layer provided by an open cell foam, and the inner layer provided a stretch fabric. The at least one mounting strap is an ear loop provided by a free-cut piece of fabric defined by an elongated narrow center portion positioned between an enlarged first end and an enlarged second end opposite the first end.

A customizable mask system can include a facemask, such as a filtering facepiece respirator, that has a first set of fastening elements integrated into an internal surface of the facemask. The system can also include a customizable mask band adapted to cover at least a portion of an external surface of the facemask. The mask band can have one or more attachment portions positioned on the mask band in locations that correspond to positions of the first set of fastening elements on the facemask and a second set of fastening elements integrated into the attachment portions. The attachment portions of the mask band can wrap around side edges of the external surface of the facemask such that the second set of fastening elements mate with the first set of fastening elements.

The present disclosure provides a respiratory protection device made of soft material comprising folds in zig-zag pattern on the main body and may be adhered to wearer's face by adhesives instead of straps. The respiratory protection device with folds is expandable from flat-fold configuration to open ready-to-use configuration, collapsible from the open ready-to-use configuration to the flat-fold configuration, and flexible to keep adhered to wearer's face when the respiratory protection device is dragged in conjunction with the movement of the wearer's face. The folding structures not only reduce the storage volume but also support the main body of the respiratory protection device to provide large air chamber for breathing comfortably in a completely sealed space. The present disclosure also provides a process of manufacturing the respiratory protection device by folding and fixing barrier layers and applying adhesives on the barrier layers.

The present application discloses a mask including a sheet, a first loop, a second loop and an elastic film. The sheet comprises a central portion, a first lateral portion, a second lateral portion and an opening. The first loop is coupled to the sheet. The second loop is coupled to the sheet. The elastic film is coupled to the sheet and covers the opening. A method of manufacturing the aforementioned face mask is also disclosed.
