Disclosed is a mask having a face contact function, wherein a structure of a mask body can be directly changed by a wearer so that the mask body does not lift off the face regardless of the structure or size of the wearer's face. To this end, the mask body comprises a close-contact member including: a first cut line which is provided in the upper portion of the left end thereof and forms a first fastening protrusion according to an external force; a cut line for the first fastening protrusion, which is provided in the lower portion of the left end thereof and provides a space in which the first fastening protrusion is to be fitted so that the upper portion is maintained in a close contact with the lower portion; a second cut line which is provided in the upper portion of the right end thereof and forms a second fastening protrusion according to the external force; and a cut line for the second fastening protrusion, which is provided in the lower portion of the right end thereof and provides a space in which the second fastening protrusion is to be fitted so that the upper portion of the right end is maintained in close contact with the lower portion of the right end. According to the present invention, even when the mask body that is in contact with the curved contour of the cheeks lifts off due to the size or curve of the wearer's face, the mask body may easily come back into contact with the wearer's cheeks. In addition, when the wearer intensely moves and an external force is applied to the mask body, the contact-close state with the cheeks can be stably maintained.

Disclosed is a mask comprising a separable holding strap, wherein the holding strap is manufactured to be separable from a mask body so that the holding strap can be reused for a new mask body. To this end, provided is a mask comprising: a mask body covering a wearer’s mouth and nose; and holding straps provided at the left side and the right side of the mask body, respectively, wherein the mask body comprises a cutting line or an uneven part which enables the holding strap to be selectively attached to or detached from the mask body. According to the present invention, the holding strap can be freely attached to or detached from the mask body even without using a separate connection device. There is no need to install the holding strap at the mask body, and thus, production of the mask can be increased three to ten times or more, and the manufacturing cost of the mask can be reduced.

The present invention provides a respirator mask (10) comprising a mask chassis (20), a seal (30), formed filter sheets (40) and a cup-shaped or dome-shaped support structure (50). The mask chassis (20) includes a circular structural framework (22) having a protrusion or nose ridge (24) at the frontal periphery of the structural framework, a pair of ribs (26) aligned preferably in a curved "X" pattern within the circular structural framework (22), a clasp arrangement (28) with four clasps (27), two attached on either side of the structural framework (22), the two clasps on same side aligned at an approximate angle of 40° with respect to one another. Elastic headbands (25) run from end to end between two corresponding clasps (27) on either side for adjusting the fit of the respirator mask (10) across a wearer's head. The face seal (30), attached to the framework (22) of the mask chassis (20) comprises either an elliptical profile having a radially inwards extending flange (32) or a flat profile. Formed filter sheets (40) are attached or welded to the external concave periphery of the mask chassis (20) thereby sitting across the exterior of the structural framework (22) and pair of ribs (26). A cup-shaped or dome-shaped structure (50) is created within the mask chassis (20) owing to the configuration of ribs (26) and/or formed filter sheets (40) attached or welded on to it and the said structure (50) comprises an air pocket inside.

The respiratory protective device includes a face seal and filter comprising two chambers, an inner chamber and outer chamber. The inner chamber is in fluid communication with the outer chamber, which is in fluid communication with the external environment. The respiratory protective device further comprises a face seal having an open annular-shaped portion, forming a flexible seal by encircling the nose and mouth of a user. The filter sealing ring includes an annular shape that is complementary to an annular-shaped portion of the face seal. The filter sealing ring may detachably mate with the face seal to define a void area. The void area is annular-shaped and suitable to receive a filter having a complementary annular-shaped flange. The shell may sealably and detachably mate with the respiratory protective device. The eye shield may detachably mate with the shell. The seal check apparatus may sealably mate with the respiratory protective device.

Appl.No PCT/KR2021/018585 Applicant LEE, Chung Ho Inventor LEE, Chung Ho
The present invention presents a nose mask for sufficiently ensuring a breathing space while preventing viruses, influenzas and various kinds of bacteria in indoor air from being inhaled through the nose. The nose mask comprises: an upper mask that covers from the upper nasal bridge to the lower nasal bridge; a lower mask, which extends downward from the lower end of the upper mask and covers from the lower nasal bridge to the lower part of nostrils; and a pair of loops formed on the left and right sides of the upper/lower mask. In addition, a first shaping wire is formed in the upper mask along an upper edge, and a second shaping wire shaped in the horizontal direction at a predetermined part of the lower mask is formed in the lower mask so that the breathing space can be ensured. The second shaping wire can be a space-forming prosthesis, which forms the breathing space immediately under the nostrils so that the lower mask is not in contact with the nostrils when a wearer of the nose mask breathes.
