METHOD OF MANUFACTURING MASK HAVING DIFFERENT INNER AND OUTER SURFACE STRUCTURES AND MASK MANUFACTURED BY SAME METHOD

Abstract

Proposed is a method of manufacturing a mask and the mask. In the mask, an inner surface sheet and an outer surface sheet have colors different from each other, and a user is capable of wearing the mask by exposing the inner surface sheet to the outside or by exposing the outer surface sheet to the outside. In addition, since a diamond-shaped portion and a linear-shaped portion are provided on the mask, the appearance of the mask is different from a mask of other people. Furthermore, since an upper covering portion and a lower covering portion which extend from the outer surface sheet and which respectively covers an upper portion and a lower portion of the inner surface sheet are provided in band shapes, aesthetic sense may further be improved when the user wears the mask by exposing the inner surface sheet to the outside.

DETAILED DESCRIPTION OF THE INVENTION

[0038] Hereinafter, other objectives and features of the present disclosure in addition to the above objectives will be apparent from the following description of embodiments with reference to the accompanying drawings.

[0039] Unless defined otherwise, all terms used herein including technical or scientific terms have the same meanings as generally understood by a person having ordinary knowledge in the art to which the present disclosure pertains. Terms such as those defined in a commonly used dictionary should be interpreted as having a meaning consistent with the meaning of the related technology, and should not be interpreted as an ideal or excessively formal meaning unless explicitly defined in the present specification.

[0040] Hereinafter, a method of manufacturing a mask having different inner and outer surface structures and the mask manufactured by the same method according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings. In describing the present disclosure, the mask having different inner and outer surface structures of the present disclosure is manufactured by the method of manufacturing the mask having different inner and outer surface structures of the present disclosure, so that the same term and the same reference numeral are used for the same configuration.

[0041] As illustrated in the drawings, the method of manufacturing the mask having different inner and outer surface structures includes: a mask body manufacturing process S1 in which a nose contact part 30 is positioned at upper portions of an inner surface sheet 10 and an outer surface sheet 20, the inner surface sheet 10 and the outer surface sheet 20 are overlapped so as to face each other, and high-frequency fusion is performed on borders of the inner surface sheet 10 and the outer surface sheet 20, thereby manufacturing a mask body 100; and an ear loop string fusion process S2 in which ear loop strings 40 are high-frequency fused on both sides of the mask body 100, respectively.

[0042] The inner surface sheet 10 and the outer surface sheet 20 of the present disclosure have different colors from each other.

[0043] As such, since the inner surface sheet 10 and the outer surface sheet 20 have different colors from each other, the color of the mask when a user wears the mask while the user exposing the inner surface sheet 10 and the color of the mask when the user wears the mask while the user exposing the outer surface sheet 20 are expressed differently, so that two color effects may be realized by using one mask.

[0044] In the mask body manufacturing process S1 of the present disclosure, center pleat portions 11 and 21, upper pleat portions 12 and 22 respectively positioned at upper portions of the center pleat portions 11 and 21, and lower pleat portions 13 and 23 respectively positioned at lower portions of the center pleat portions 11 and 21 are respectively provided along a horizontal length direction of the inner surface sheet 10 and a horizontal length direction of the outer surface sheet 20. Furthermore, the inner surface sheet 10 and the outer surface sheet 20 are overlapped such that the center pleat portions 11 and 21, the upper pleat portions 12 and 22, and the lower pleat portions 13 and 23 respectively provided at the inner surface sheet 10 and the outer surface sheet 20 are facing each other, and high-frequency fusion is performed on the inner surface sheet 10 and the outer surface sheet 20, thereby manufacturing the mask body 100.

[0045] As illustrated in the drawings, the center pleat portions 11 and 21, the upper pleat portions 12 and 22, and the lower pleat portions 13 and 23 are provided along a horizontal length direction of the mask body 100. The reason for having the center pleat portions 11 and 21, the upper pleat portions 12 and 22, and the lower pleat portions 13 and 23 as described above is to provide a diamond-shaped portion 60 and a linear-shaped portion 70 on the mask body 100 of the present disclosure.

[0046] To this end, the mask body manufacturing process S1 of the present disclosure includes a pleat portion folding process S11 and a pleat portion fusion process S12.

[0047] As illustrated in FIGS. 3 and 4, in the pleat portion folding process S11, first side ends of the upper pleat portions 12 and 22 and first side ends of the lower pleat portions 13 and 23 are folded to be positioned adjacent to first side ends of the center pleat portions 11 and 21, respectively, and second side ends of the upper pleat portions 12 and 22 and second side ends of the lower pleat portions 13 and 23 are folded to be positioned adjacent to second side ends of the center pleat portions 11 and 21, respectively.

[0048] That is, as illustrated in FIG. 3, first sides of the upper pleat portions 12 and 22 are folded and first sides of the lower pleat portions 13 and 23 are folded, and then the first side ends of the upper pleat portions 12 and 22 that are folded and the first side ends of the lower pleat portions 13 and 23 that are folded are positioned at the first side ends of the center pleat portions 11 and 21.

[0049] As such, when the first side ends of both the upper pleat portions 12 and 22 and the lower pleat portions 13 and 23 having the first side folded are positioned adjacent to the first side ends of the center pleat portions 11 and 21, upper and lower portions of a first side of the mask body 100 formed of the inner surface sheet 10 and the outer surface sheet 20 are naturally pulled toward the center pleat portions 11 and 21.

[0050] In addition, as illustrated in FIG. 4, second sides of the upper pleat portions 12 and 22 are folded and second sides of the lower pleat portions 13 and 23 are folded, and then the second side ends of the upper pleat portions 12 and 22 and the second side ends of the lower pleat portions 13 and 23 are positioned at the second side ends of the center pleat portions 11 and 21.

[0051] As such, when the second side ends of both the upper pleat portions 12 and 22 and the lower pleat portions 13 and 23 having the second side folded are positioned adjacent to the second side ends of the center pleat portions 11 and 21, upper and lower portions of a second side of the mask body 100 formed of the inner surface sheet 10 and the outer surface sheet 20 are naturally pulled toward the center pleat portions 11 and 21.

[0052] In the pleat portion fusion process S12 of the present disclosure, the first side ends and the second side ends of the upper pleat portions 12 and 22 that are folded and the first side ends and the second side ends of the lower pleat portions 13 and 23 that are folded are high-frequency fused and fixed by pleat fusion portions 50.

[0053] That is, as illustrated in FIG. 5, the first side ends of the upper pleat portions 12 and 22 that are folded and the first side ends of the lower pleat portions 13 and 23 that are folded are high-frequency fused and fixed to a first side of the outer surface sheet 20 of the mask body 100 that is pulled toward the center pleat portions 11 and 21 by the pleat fusion portions 50.

[0054] In addition, as illustrated in FIG. 6, the second side ends of the upper pleat portions 12 and 22 that are folded and the second side ends of the lower pleat portions 13 and 23 that are folded are high-frequency fused and fixed to a second side of the outer surface sheet 20 of the mask body 100 that is pulled toward the center pleat portions 11 and 21 by the pleat fusion portions 50.

[0055] In the present disclosure constituted as described above, as illustrated in FIGS. 7 and 8, the linear-shaped portion 70 is provided on the outer surface sheet 20 forming the mask body 100 by performing the pleat portion folding process S11 and the pleat portion fusion process S12, the linear-shaped portion 70 being provided along the horizontal length direction of the outer surface sheet 20.

[0056] In addition, as illustrated in FIGS. 9 and 10, on the inner surface sheet 10 forming the mask body 100, the diamond-shaped portion 60 is provided along the horizontal length direction of the inner surface sheet 10.

[0057] Therefore, as illustrated in FIG. 11, when a user wears the mask body 100 while the outer surface sheet 20 is exposed, the linear-shaped portion 70 is exposed to the outside, so that the appearance of the mask body 100 may be elegantly expressed by the linear-shaped portion 70 and the color of the outer surface sheet 20.

[0058] In addition, as illustrated in FIG. 12, when the user wears the mask body 100 while the inner surface sheet 10 is exposed, the diamond-shaped portion 60 is exposed to the outside, so that the appearance of the mask body 100 may be elegantly expressed by the diamond-shaped portion 60 and the color of the inner surface sheet 10.

[0059] In the method of manufacturing the mask having different inner and outer surface structures of the present disclosure, upper and lower ends of the outer surface sheet 20 are provided such that the upper and lower ends of the outer surface sheet 20 further extend with respect to upper and lower ends of the inner surface sheet 10. Furthermore, in the mask body manufacturing process S1, before the inner surface sheet 10 and the outer surface sheet 20 are overlapped, the upper and lower ends of the outer surface sheet 20 are respectively folded toward the upper and lower ends of the inner surface sheet 10 and are high-frequency fused, so that an upper covering portion 24 and a lower covering portion 25 are respectively provided at the upper end and the lower end of the inner surface sheet 10.

[0060] In the present disclosure constituted as described above, as illustrated in FIG. 12, when the user wears the mask body 100 such that the inner surface sheet 10 is exposed to the outside, the upper covering portion 24 and the lower covering portion 25 having the color of the outer surface sheet 20 are respectively exposed on the upper portion and the lower portion of the inner surface sheet 10, and the inner surface sheet 10 may generally be expressed in dual colors by the upper covering portion 24 and the lower covering portion 25, so that elegance and aesthetic sense of the mask body 100 may further be improved.

[0061] The mask having different inner and outer surface structures of the present disclosure relates to a mask which includes the mask body 100 having the upper end provided with the nose contact part 30 and which includes the ear loop strings 40 that are respectively provided at both sides of the mask body 100, and is manufactured by the method of manufacturing the mask having different inner and outer surface structures of the present disclosure.

[0062] The mask body 100 of the present disclosure includes: the inner surface sheet 10 having various colors; the outer surface sheet 20 having the color different from the color of the inner surface sheet 10; the diamond-shaped portion 60 provided on the inner surface sheet 10 along the horizontal length direction of the mask body 100; first extension portions 61 respectively provided at an upper portion and a lower portion of the diamond-shaped portion 60; the linear-shaped portion 70 provided on the outer surface sheet 20 along the horizontal length direction of the mask body 100; and second extension portions 71 respectively provided at an upper portion and a lower portion of the linear-shaped portion 70.

[0063] The first extension portions 61 is provided so that the mask body 100 is unfolded over a part of the user's face when the user wears the mask body 100 while the diamond-shaped portion 60 is exposed to the outside, and the second extension portions 71 is provided so that the mask body 100 is unfolded over the part of the user's face when the user wears the mask body 100 while the linear-shaped portion 70 is exposed to the outside.

[0064] In the present disclosure constituted as described above, when the user wears the mask body 100 by exposing the inner surface sheet 10 to the outside or by exposing the outer surface sheet 20 to the outside, two types of colors are capable of being expressed by using one mask body 100 due to the inner surface sheet 10 and the outer surface sheet 20. Therefore, for example, as the user wears the mask body 100 by selectively exposing the desired color to the outside, the color of the clothes that the user wears and the color of the mask body 100 may be well-matched with each other.

[0065] In the mask having different inner and outer surface structures of the present disclosure, as the upper portion and the lower portion of the inner surface sheet 10 are respectively covered with the upper portion and the lower portion of the outer surface sheet 20, the upper covering portion 24 and the lower covering portion 25 are respectively provided on the upper portion and the lower portion of the inner surface sheet 10.

[0066] Accordingly, since the upper portion and the lower portion of the inner surface sheet 10 may be expressed as band shapes by the upper covering portion 24 and the lower covering portion 25, the overall color of the mask body 100 may be more elegantly expressed by the upper covering portion 24 and the lower covering portion 25 having the band shapes and having the color different from the color of the inner surface sheet 10.

[0067] Although the present disclosure has been described in terms of specific items such as detailed elements as well as the limited embodiments and the drawings, they are only provided to help more general understanding of the present disclosure, and the present disclosure is not limited to the above embodiments. It will be appreciated by those skilled in the art to which the present disclosure pertains that various modifications and changes may be made from the above description.

[0068] Therefore, the spirit of the present disclosure should not be limited to the described exemplary embodiments, and all things equal or equivalent to the claims as well as the claims to be described later fall within the scope of the concept of the present disclosure.
