Additionally, the first portion 302 may comprise a crease 307, the second portion 304 may comprise a crease 311, and the third portion 306 may comprise a crease 309.

[0043] As shown in FIG. 3B, the method may comprise folding the first portion 302 onto the second portion 304 along the first crease 303 to align the edges of the first cut-out 221. The method may also comprise folding the third portion 306 onto the second portion 304 along the second crease 305 to align the edges of the second cut-out 222. The method may further comprise welding the edges of the first cut-out 221, such that the first portion 302 and the second portion 304 are now connected at the edges of the first cut-out 221. Additionally, the method may comprise welding the edges of the second cut-out 222, such that the second portion 304 and the third portion 306 are now connected at the edges of the second cut-out 222. As, shown in FIG. 3C, the first cut-out 221 may comprise edges AB and A'B' and the second cut-out may comprise edges CD and CD' .

[0044] In the embodiment shown in FIG. 3B, the first portion 302 and the third portion 306 may meet along the creases 307 (not shown) and 309 to form a fourth portion 308 and fifth portion 310. In the embodiment shown, the formation of the fourth portion 308 and fifth portion 310 may align the edges of the third cut-out 223. In other words, the edges of the third cut-out 223 may form one edge of the fourth portion 308 and fifth portion 310 of the mask shape 220. [0045] The method may continue as shown in FIGS. 3D-3G. In the embodiment shown, the fourth 308 and fifth 310 portions of the mask shape 220 may be folded onto the first portion 302 along the creases 309 and 307. Then, as shown in FIG. 3E, the edges of the third cut-out 223 may be welded. As shown in FIG. 3F, the third cut-out 223 may comprise edges EF and E'F'. Welding the edges of the three cut-outs 221, 222, and 223 may create a three-dimensional mask shape 220 from the originally flat nonwoven fabric 200, wherein the three-dimensional shape may fit about the face of a user. A further step of the method, as shown in FIG. 3G, may comprise folding the third portion 306 of the mask shape 220 and half of the second portion 304 of the mask shape 220 onto the fourth portion 308. The second portion 304 may fold in half along the crease 311. FIG. 3G illustrates a final folded mask shape 230 of the foldable, disposable mask. The mask may be packaged in this shape. Additionally, the mask may be unfolded from this shape to be worn by a user, and may be re-folded back into this shape when desired by the user, such as when the user wishes to carry the mask. The mask shape may be repeatedly unfolded and folded via the creases 202 of the mask shape.

[0046] In some embodiments, the method may further comprise attaching nose clips, head straps, and other additional parts, printing onto the mask fabric (such as a label or instructions for use), and the method may comprise packaging the folded mask. In some cases, a plurality of masks may be formed using this method and then packaged together in a group. In some embodiments, the methods described may be completely manually, and in other embodiments, they may be completed automatically. In yet other embodiments, some steps of the methods may be completed manually and some steps may be completed automatically.

[0047] Referring now to FIG. 4, and exemplary embodiment of the finished folded mask shape 230 is shown, wherein this specific example shows possible measurements for the folded mask shape 230. In some embodiments, the length 402 of the edges of the third cut-out 223 may be approximately 52 mm. Additionally, the angle 404 between the edges of the third cut-out 223 and the second crease 305 may be approximately 40 degrees. In some embodiments, the length 406 of the second crease 305 may be approximately 52 mm. Similarly, the first crease 303 may mirror the second crease 305 about the crease 311, and therefore may also be approximately 52 mm in length. Additionally, the angle 408 between the second crease 305 and the crease 311 may be approximately 40 degrees. In some embodiments, the length 410 of the edges of the second cut-out 222 may be approximately 58 mm. Similarly, the first cut-out 221 may mirror the second cut-out 222 about the crease 311, and therefore the edges of the first cut-out 221 may also be approximately 58 mm in length. Additionally, the angle 412 between the line created by the second crease 305 and the edges of the second cut-out 222 may be approximately 20 degrees. In some embodiments, the shape may comprise at least five creases, the total height of the shape 230 may not exceed 150 millimeters, and the total width of the shape 230 may not exceed 180 millimeters.

[0048] Additional methods disclosed herein may comprise steps of molding and folding to form a specific foldable mask shape. In the embodiment of FIGS. 5A-5D, a flat nonwoven fabric 500 may be molded to create a mask shape 520. In some embodiments, the step of molding may be accomplished by pressing the flat nonwoven fabric 500 between an upper part of the mold and a lower part of the mold. Additionally, the edges 504 of the mask shape 520 may be provided or stamped into the fabric 500. As shown in FIG. 5 A, the excess fabric 501 may be removed from the mask shape 520 at the edges 504. In some embodiments, the steps of molding and removing the excess fabric 501 may be accomplished simultaneously. Molding may create a three-dimensional mask shape from the flat nonwoven fabric material that fits about the face of a user.

[0049] In some embodiments, the molded mask shape 520 may comprise a plurality of creases 502 that allow for the mask shape 520 to fold along the creases 502. In the embodiment of FIG. 5C, the mask shape 520 may be folded into a first folded mask shape 521. In the embodiment of FIG. 5D, the mask shape 520 may be folded into a second folded mask shape 522. In some embodiments, the second folded mask shape 522 may be similar to the first folded mask shape 521, such that the second folded mask shape 522 may be created by further folding the first folded mask shape 521. The mask may be packaged in the shapes 521 and 522. Additionally, the mask may be unfolded from this shape to be worn by a user, and may be refolded back into this shape when desired by the user, such as when the user wishes to carry the mask. The mask may be repeatedly unfolded and folded via the creases 502 of the mask shape 520. In some embodiments, the method may further comprise attaching nose clips, head straps, and other additional parts, printing onto the mask fabric (such as a label or instructions for use), and the method may comprise packaging the folded mask. In some cases, a plurality of masks may be formed using this method and then packaged together in a group.

[0050] The method shown in FIGS. 6A-6D illustrates the formation of the first folded mask shape 521. In FIG. 6 A, a first portion of the mask 602 may be folded along a first set of creases 621, 622, and 623 to lay behind a second portion of the mask 604. The first portion 602 may comprise additional creases 624 and 625 that may facilitate in folding the first portion 602 behind the second portion 604 of the mask shape 520, as shown in FIG. 6A. In FIG. 6B, the first portion 602 is located behind the second portion 604. Then, in FIG. 6C, a third portion 606 of the mask shape 520 may be folded along a second set of creases 626 and 627 to lay behind the second portion 604 of the mask shape 520. The third portion 606 may comprise an additional crease 628 that may facilitate in folding the third portion 606 behind the second portion 604. These folding methods may form the first folded mask shape 521, as shown in FIG. 6D.

[0051] The method shown in FIGS. 7A-7D illustrates the formation of the second folded mask shape 522. In some embodiments, the method shown may be a continuation of the method shown in FIGS. 6A-6D, wherein the method may begin with the first folded mask shape 521, as shown in FIG. 7A. The method may comprise folding a fourth portion 608 and fifth portion 610 of the mask shape 520. The fifth portion 610 may be folded along a crease 626 as well as a set of creases 632 and 633, and may be folded between the second portion 604 and third portion 606 of the mask shape 520, as shown in FIG. 7B. The fourth portion 608 may be folded along a crease 621, as well as a set of creases 630 and 631, and may be folded between the first portion 602 and second portion 604 of the mask shape 520, as shown in FIG. 7C. These folding methods may form the second folded mask shape 522, as shown in FIG. 7D.

[0052] Referring now to FIG. 8, and exemplary embodiment of the finished first folded mask shape 521 is shown, wherein this specific example shows possible measurements for the mask shape 521. In some embodiments, the mask shape 521 may be symmetrical about an axis 802. In some embodiments, the length 804 of the crease 622 may be approximately 52 mm. Similarly, the crease 627 may mirror the crease 622 about the axis, and therefore may also be approximately 52 mm in length. Additionally, the angle 806 between the creases 622 and 627 may be approximately 80 degrees. In some embodiments, the length 808 of the crease 630 may be approximately 64 mm. Similarly, the crease 632 may mirror the crease 630 about the axis 802, and therefore may also be approximately 64 mm in length. Additionally, the angle 810 between the crease 603 and the line created by the crease 622 may be approximately 48 degrees. In some embodiments, the length 812 of the crease 621 may be approximately 58 mm. Similarly, the crease 626 may mirror the crease 621 about the axis 802, and therefore crease 626 may also be approximately 58 mm in length. Additionally, the angle 814 between the crease 621 and the line created by the crease 622 may be approximately 20 degrees. In some embodiments, the shape may comprise at least five creases, the total height of the shape 230 may not exceed 150 millimeters, and the total width of the shape 230 may not exceed 180 millimeters.

[0053] In some embodiments, the foldable masks formed by any of the methods described above may be packaged with other foldable masks for transport or sales of the masks. For example, the foldable masks described above may be more compact that traditional foldable masks, and therefore may be packaged in a smaller container. Additionally, the masks may be packaged in a container such that the masks are easy to individually remove from the container, similar to a facial tissue box. In another example, the masks may be packaged in a roll and may be individually removed or torn from the roll. In yet another example, the masks may be packaged to be sold individually from a vending machine.
