A multilayered face-covering is provided with at least two layers and joined with a centrally located merge stitch or nose seam. The outer is a thicker knitted cloth material with a higher thread-weight and/or thread-count than the inner layer to create an increased stiffness on the outer layer that resists compressive buckling. The inner layer is lightweight and provides a comfortable cushion against the user's skin. Face-covering can also include a intermediate layer sandwiched between inner and outer layers. The intermediate layer provides additional filtering of inhaled and/or exhaled particles and enhances the outer layer's rigidity.

The present invention discloses a three-dimensional mask with an expression window, and a manufacturing method and production equipment thereof; wherein a three-dimensional mask that splits open toward left and right as a bulge is provided for wearing. In a shielding region of mask body corresponding to a user's mouth, a refractive diaphragm is replaceably and tightly disposed and is expanded associatively following a preparation operation, so that a person with whom the user communicates can see through the expression of the user's mouth and the verbal the user manifests. Therefore, a three-dimensional mask for context communication and a coherent manufacturing method and production equipment thereof are provided, with some devices of the production equipment being able to be adapted in a same working region.

A filter mask, including a flexible filtering mask body having an outside surface and an opposite inside surface shaped to cover a nose and a mouth of a user, the mask body having a midbody portion extending between a right body side and a left body side. The filtering mask body is moveable between a first configuration having a first horizontal extent of the outside surface along the midbody portion and a second configuration in having a second horizontal extent of the outside surface along the midbody portion, the second extent being greater than the first extent. The filter mask includes a retainer system to hold the mask body to a user's head, the retainer system arranged to draw at only a single left-side location and only a single right-side location of the mask body when used reconfigure the filtering mask body from the first configuration to the second configuration.

The present invention relates to personal protective equipment, specifically to a filtering device for the protection of the respiratory tract, which can be worn on the face of a user. In particular, the present invention relates to a wearable filtering mask comprising said filtering device (filtering means) for the protection of the respiratory tract and, furthermore, it relates to said filtering device (filtering means), preferably in the form of multilayer filtering means. Lastly, the present invention relates to a face mask that can be worn and configured to filter air.

A face mask configured to be worn on a human head includes a face shield and an ear loop. The ear loop is connected to a lateral side of the face shield. The ear loop defines an elongated narrow center portion positioned between an enlarged first end and an enlarged second end opposite the first end. The enlarged first end is connected to an upper portion of the lateral side of the face shield. The enlarged second end is connected to a lower portion of the lateral side of the face shield. The enlarged first end overlaps the enlarged second end along the lateral side of the face shield.

A face mask includes a piece of fabric including a main body portion, a first leg extending from first side of the main body portion, and a second leg extending from a second side of the main body portion. A first plurality of slots are arranged along a first side perimeter of the main body portion, and a second plurality of slots are arranged along a second side perimeter of the main body portion. At least one first fold in the piece of fabric extends between the first plurality of slots and at least one second fold extends between the second plurality of slots. The first plurality of slots are aligned and the first leg extends through the first plurality of slots. The second plurality of slots are also aligned and the second leg extends through the second plurality of slots.

A face mask of the present disclosure can create a space preventing a user's mouth from directly contacting the face mask. One example of the face mask includes a center sheet, two side sheets, and two fixing parts. The center sheet is a rectangular fabric. The two side sheets are coupled to long sides of the center sheet separately with a first edge of the side sheet. The fixing part is coupled to a second edge of the side sheet, and the second edge of the side sheet is opposite to the first edge of the side sheet.

A face mask may include a main body that has a rear, a front, a bottom, a top, and a pair of opposing side portions extending between the top and the bottom. The face mask may also include an opening formed through the front and the rear of the main body and an opening cover member moveable between an opened position and a closed position. The face mask may further include a first fastener member connected to the main body and positioned to surround the opening and a second fastener member connected to an inner portion of the opening cover member and adapted to engage the first fastener member to secure the opening cover member to the main body.

The pocket mask apparatus is a readily carriable respiratory mask. The pocket mask apparatus contains a respiratory mask and a mask pouch. The respiratory mask contains a mask body and at least one strap. The mask body contains at least one folding seam. The mask pouch contains a pouch body, a mask cavity, and a pouch opening. The respiratory mask is positioned within the mask pouch. The mask body is configured to fold about the at least one folding seam into a folded configuration. Each of the at least one strap is terminally connected to the mask body. Each of the at least one strap is positioned opposite to each other along the mask body. The mask cavity traverses into the pouch body. The mask cavity is delineated by the pouch opening. The mask cavity is configured to receive the respiratory mask in the folded configuration through the pouch opening.

A sheet-like filter includes a first fiber that is mainly composed of polylactic acid, and a second fiber that is mainly composed of polylactic acid and has a core portion and a cover layer covering the core portion, in which the cover layer functions as a binder for fusing the first fiber and the second fiber. In addition, when a melting point of the core portion is denoted by Tm1 and a melting point of the cover layer is denoted by Tm2, it may be Tm2<Tm1.
