Abstract
The face mask mainly includes a main piece. An upper portion of the main piece is bended backward at a first upper bending section, and then extended downward to form a first upper piece. A lower portion of the first upper piece is bended backward at a second upper bending section, and then extended upward to form a second upper piece. A lower portion of the main piece is similarly bended and extended to form a first lower piece and a second lower piece. A main piece height, a second upper piece height, and a second lower piece height, relative to a face mask height, are respectively between 42%˜64%, 42%˜48% and 31%˜39%. The main piece is vertically positioned towards a lower half of the face mask for a vertical distance, which is between 2% and 10% relative to the face mask height.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description pro ides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
[0020] As shown in
[0021] a rectangular and planar main piece 1 having a height A where a first lateral line 11 in the middle of main piece 1 horizontally divides the main piece 1 into an upper portion and a lower portion;
[0022] a first upper bending section 21 having an inverted U-shaped cross-section where a front edge of the first upper bending section 21 is joined to an entire upper edge of the main piece 1;
[0023] a rectangular and planar first upper piece 22 immediately attached to the upper portion of a back side of the main piece 1 where an upper edge of the first upper piece 22 is joined to an entire back edge of the first upper bending section 21;
[0024] a second upper bending section 23 having a U-shaped cross-section where a front edge of second upper bending section 23 is joined to an entire lower edge of the first upper piece 22;
[0025] a rectangular and planar second upper piece 24 immediately attached to a back side of the first upper piece 22 where a lower edge of the second upper piece 24 is joined to an entire back edge of the second upper bending section 23, and the second upper piece 24 has a height B;
[0026] a first lower bending section 31 having a U-shaped cross-section where a front edge of the first lower bending section 31 is joined to an entire lower edge of the main piece 1;
[0027] a rectangular and planar first lower piece 32 immediately attached to the lower portion of the back side of the main piece 1 where a lower edge of the first lower piece 32 is joined to an entire back edge of the first lower bending section 31;
[0028] a second lower bending section 33 having an inverted U-shaped cross-section where a front edge of second lower bending section 33 is joined to an entire upper edge of the first lower piece 32; and
[0029] a rectangular and planar second lower piece 34 immediately attached to a back side of the first lower piece 32 where an upper edge of the second lower piece 34 is joined to an entire back edge of the second lower bending section 33, and the second lower piece 34 has a height C.
[0030] The height of the face mask between an upper edge of the second upper piece 24 and a lower edge of second lower piece 34 is T which is greater than the main piece height A. A second lateral line L in the middle of face mask horizontally divides the face mask into an upper portion and a lower portion. The first lateral line 11 and the second lateral line L has a vertical distance D in between.
[0031] The main piece height A, relative to the face mask height T, is between 42% and 64%. The second upper piece height B, relative to face mask height. T, is between 42% and 48%. The second lower piece height C, relative to the face mask height T, is between 31% and 39%. The first lateral line 11 is located lower than the second lateral line L, and the vertical distance D, relative to the face mask height T, is between 2% and 10%.
[0032] As shown in
[0033] Furthermore, as the location of a wearer's nose and mouth corresponds to a lower part of the face mask, the second upper piece height B is designed to be between 42% and 48% of the face mask height T, and the second lower piece height C is designed to be between 31% and 39% of the face mask height T. By having this asymmetric arrangement with the second upper piece height B greater than the second lower piece height C, the wearer's nose and mouth would be directly behind the main piece 1 after the face mask is expanded and worn to enhance breathability. In addition, the face mask may still adequately cover the wearer's chin to provide effective protection without. sacrificing comfort. Specifically, the first lateral line 11 of the main piece 1 is vertically below the second lateral line L of the face mask height T, and the vertical distance D relative to the face mask height T is between 2% and 10%. In other words, the distance from the upper edge of the second upper piece 24 (also the upper edge of the face mask) to the first lateral line 11 relative to the face ask height T is between 52% and 60%. The main piece 1, without any fold, maximizes the breathability of the face mask.
