Description

[Technical field]

[0001] The present invention relates to a mask for preventing glasses from fogging up, and more particularly to a mask for preventing glasses from fogging up, which is configured to maintain a close contact with the nose when the mask is worn by using an anti-fogging wrinkle member formed integrally with the mask body, thereby improving the wearing comfort and preventing glasses from fogging up by blocking the upward movement of exhaled air. [Background technology]

[0002] Generally, masks are worn to filter out harmful dust particles such as yellow sand or particulate matter mixed in the outside air, as well as bacteria such as COVID-19, helping to ensure that only harmless air can be breathed.

[0003] However, conventional masks do not completely fit the wearer's nose, leaving gaps on both sides of the nose, allowing dust and harmful substances to enter into these gaps, resulting in a reduced dust-proofing effect.

[0004] In addition, when walking or working while wearing glasses, the breath rises along the inner surface of the mask body when breathing, causing the mask and glasses to fog up, thus obstructing the user's field of vision, and causing great inconvenience when walking or working, resulting in many problems.

[0005] Therefore, Korean Patent Publication No. 10-2022-0104084 discloses a removable mask that prevents fogging by comprising a mask body and a double barrier membrane that prevents air from leaking out of the upper part of the mask body.

[0006] However, in the conventional technology, the mask body and the double barrier film are constructed separately, and therefore the double barrier film must be manufactured and then attached to the manufactured mask body separately, which makes the manufacturing process complicated and difficult. When the mask is worn, the double barrier film is easily separated from the mask body, reducing the anti-fogging effect. In addition, there are problems in that contaminants can enter the inside of the mask through small gaps caused by poor seams or separation. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Korean Patent Publication No. 10-2022-0104084 Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention has been proposed to improve the above-mentioned problems, and its purpose is to provide an improved anti-fog mask for glasses that has an anti-fog wrinkle member formed integrally with the mask body, which can maintain a close contact with the nose when the mask is worn, improving the wearing comfort and blocking the upward movement of exhaled air to prevent fogging of glasses. [Means for solving the problem]

[0009] The above-mentioned object is achieved by an anti-fogging mask for glasses, comprising: a mask body formed from a plate-like member and worn on the face of a user; a pair of hanging bands, both ends of which are ultrasonically fused to both sides of the mask body; and an anti-fogging wrinkle member, which is integrally formed on the inner surface of the upper end of the mask body, and has a number of folds formed thereon in which convex and concave portions are continuously formed in a zigzag shape in the vertical direction on a cross section, and has exhalation exhaust holes formed on the bottom surfaces of the convex portions, wherein when the mask is worn, the cushion formed in the front-rear direction by the folds keeps the rear surface of the anti-fogging wrinkle member in close contact with the nose and face, improving the wearing comfort, and when the wearer exhales through the exhalation exhaust holes, the mask blocks the upward movement of the exhaled air coming out through the nose and mouth, and quickly releases the exhaled air to the sides of the mask body, preventing fogging of glasses.

[0010] Here, the mask body and the anti-fogging wrinkle member are manufactured by folding the upper end of a plate-like member from top to bottom in a zigzag shape to form a number of folds with convex and concave portions continuously formed in a zigzag shape to form the anti-fogging wrinkle member, forming the mask body at the lower end of the plate-like member, and then ultrasonically fusing both ends of the anti-fogging wrinkle member to the mask body to integrally form the anti-fogging wrinkle member with the mask body.

[0011] The anti-fogging wrinkle member is characterized in that a nose accommodating cutout groove is formed in the center to accommodate the nose in the front-rear direction, and when the mask is worn, as the nose is accommodated in the nose accommodating cutout groove of the anti-fogging wrinkle member, the center is closely attached to the nose area with uniform pressure overall, and both sides are closely attached to the face area, so that the mask body does not float up.

[0012] The mask body and the anti-fogging wrinkle member are manufactured by forming a round cutout at the central upper end of a plate-like member so as to be concave downward, folding the upper end of the plate-like member in a zigzag shape from top to bottom to form a number of folds with convex and concave portions formed continuously in a zigzag shape, and folding the cutout at the center of the folds in turn to form a three-dimensional nose-accommodating cutout groove whose width decreases from rear to front in accordance with the shape of the nose, thereby forming the anti-fogging wrinkle member, forming a mask body at the lower end of the plate-like member, and then ultrasonically fusing both ends of the anti-fogging wrinkle member to the mask body to integrally form the anti-fogging wrinkle member with the mask body.

[0013] The mask body comprises a double layer of inner and outer skins made of nonwoven fabric, a filter made of meltblown nonwoven fabric disposed between the inner and outer skins, and a carbon nanomesh disposed between the inner and filter and between the filter and the outer skin, respectively. The inner skin is impregnated with an inner skin impregnation solution prepared by adding 10 parts by weight of nano platinum, 5 parts by weight of zinc sulfate, and 5 parts by weight of allantoin to 100 parts by weight of polypropylene resin, and then dried before use. The outer skin is impregnated with an outer skin impregnation solution prepared by adding 5 parts by weight of charcoal powder, 10 parts by weight of diphenylphosphoryl azide, and 5 parts by weight of a mixture of carboxylic acid and rosin in a weight ratio of 2:1 to 100 parts by weight of polypropylene resin, and then dried before use. Effect of the Invention

[0014] The anti-fog mask for glasses according to the present invention has an anti-fog wrinkle member formed integrally with the inside of the upper end of the mask body, which keeps the mask in a stable wearing state, and prevents air flowing through the upper side of the mask and the wearer's breath from leaking onto the glasses, thereby preventing the glasses from fogging up.

[0015] In addition, the eyeglasses anti-fogging mask according to the present invention exerts the greatest tension on the highest part of the nose part of the mask, but the incision in the nose part distributes the tension on the face more evenly, thereby reducing the induction of pain.

[0016] In addition, the anti-fog glasses mask according to the present invention has the effect of preventing glasses from fogging up due to the uniform expansion of the folds (unevenness at the folds) even when you are out of breath, i.e., when exhaling forcefully forward during exercise or strenuous work.

[0017] In addition, the anti-fog eyeglass mask according to the present invention is a simple folding type made of antibacterial, antiviral and anti-moisture material, with the mask and anti-fog wrinkle member (convex and concave) being made in one piece, which has the effect of preventing contamination from small gaps due to poor seams or separation in advance.

[0018] In addition, the glasses fogging prevention mask according to the present invention has an improved effect of contributing to the promotion of the user's health by improving resistance to particulate matter penetration as well as cold protection through a mask body consisting of a double layer of nonwoven fabric, a filter placed between the double layer, and two carbon nanomesh bodies respectively sandwiched between the double layer and the filter, and by providing at least one antibacterial layer to improve resistance to bacteria.

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] 1 to 3, the anti-fog eyeglasses mask according to the present invention is characterized in that it maintains a close contact with the nose area to improve the wearing comfort and prevents eyeglasses from fogging by blocking the upward movement of exhaled air, and comprises a mask body 100, a hanging strap 200, and an anti-fog wrinkle member 300.

[0022] First, the mask body 100 is formed of a plate-shaped member and is worn on the face of a user. It is configured to cover the mouth and nose of the user to block external air, and is mainly made of filter paper having a filtering function, and can be made of, for example, polypropylene spunbond nonwoven fabric, polyester or polypropylene needle punching nonwoven fabric, etc.

[0023] That is, the mask body 100 may be manufactured by laminating polypropylene spunbond nonwoven fabric, polyester or polypropylene needle punching nonwoven fabric, etc., and then ultrasonically fusing the edges.

[0024] Here, it is preferable that the mask body 100 is formed in a plate shape including a plurality of horizontal wrinkles 110, and the wrinkles 110 expand the area in the vertical direction, thereby forming a curved surface corresponding to the user's face when worn.

[0025] Next, the hanging strap 200 is ultrasonically welded at both ends of both sides of the mask body, and supports the mask body 100 on the left and right ears of the user, and is composed of a left hanging band and a right hanging band 210, 220, which may be formed of a thin string. The hanging strap 200 is preferably ring-shaped with both ends connected, and preferably has a small amount of elasticity in the longitudinal direction. However, it is not limited thereto.

[0026] Next, the anti-fogging wrinkle member 300 is integrally formed on the inner surface of the upper end of the mask body 100, and is configured to form a number of folding wrinkles 310 in which convex portions 311 and concave portions 312 are continuously formed in a zigzag shape in the vertical direction on the cross section, and to form exhalation exhaust holes 313 on the bottom surfaces of the convex portions 311, respectively.

[0027] Here, the anti-fogging wrinkle member 300 is integrally formed in the left-right direction over the entire upper end of the mask body 100, and is configured to cover the entire upper end of the mask body 100.

[0028] 4, the anti-fogging wrinkle member 300 is configured to maintain the rear surface of the anti-fogging wrinkle member 300 in close contact with the nose and face and improve wearing comfort by the cushion formed in the front-back direction by the folding wrinkles 310 when wearing the mask. In addition, when the wearer exhales through the exhalation exhaust hole 313, the anti-fogging wrinkle member 300 is configured to block the upward movement of the exhaled air coming out through the nose and mouth and quickly release the exhaled air to the side of the mask body 100, thereby preventing fogging on glasses.

[0029] Furthermore, the mask body 100 and the anti-fogging wrinkle member 300 which are integrally formed can be manufactured integrally from a single plate-like member 300-1.

[0030] 5a to 5c, the mask body 100 and the anti-fogging wrinkle member 300 are manufactured by folding the upper end 300-1 of the plate-shaped member 10 from top to bottom in a zigzag shape to form a number of folds 310 in which convex portions 311 and concave portions 312 are continuously formed in a zigzag shape, and the anti-fogging wrinkle member 300 is formed at the lower end 100-1 of the plate-shaped member 10. Then, both ends of the anti-fogging wrinkle member 300 are ultrasonically fused to the mask body 100, so that the anti-fogging wrinkle member 300 is integrally formed with the mask body 100.

[0031] By manufacturing in this manner, the mask body 100 and the anti-fogging wrinkle member 300 can be formed at once from a single plate-like member 10, which has the advantages of being easy to manufacture, enabling mass production, and reducing manufacturing costs. In addition, the mask body 100 and the anti-fogging wrinkle member 300 are made of a single piece of antibacterial, antiviral, and moisture-resistant material in a simple folding system, which has the advantage of preventing contamination from small gaps due to poor seams or separation in advance.

[0032] Meanwhile, according to the present invention, as shown in FIG. 6, it is preferable that the anti-fogging wrinkle member 300 has a nose receiving cutout 320 formed in the center thereof for receiving the nose in the front-rear direction.

[0033] In other words, when the mask is worn, as the wearer's nose is accommodated in the nose accommodating cutout groove 320, the anti-fogging wrinkle member 300 has uniform pressure overall, the center portion is in close contact with the nose area, and both sides are in close contact with the face area, so that the mask body 100 does not lift up from the face.

[0034] In addition, the nose part of the mask is located at the highest part and is subjected to the greatest tension, but the nose receiving incision groove 320 formed in the nose part distributes the tension applied to the face more evenly, improving the induction of pain.

[0035] In addition, even when you are out of breath, i.e. when you exhale forcefully forward during exercise or strenuous exertion, your glasses will not fog up due to the uniform expansion of the folds (unevenness of the folded parts).

[0036] Therefore, the anti-fogging wrinkle member 300 can maintain the mask body 100 in close contact with the nose and face, improving the wearing comfort and reliably blocking the upward flow of exhaled air.

[0037] Meanwhile, the mask body 100 and the anti-fogging wrinkle member 300 having the nose receiving groove 320 formed therein can also be manufactured from one plate-like member 10 .

[0038] 7a to 7c, a round cutout 320-1 is formed at the upper center of the plate-like member 10 so as to be concave downward, and the upper end 300-1 of the plate-like member 10 is folded in a zigzag shape from top to bottom to form a number of folds 310 in which convex parts 311 and concave parts 312 are continuously formed in a zigzag shape. The cutout 320-1 at the center of the folds 310 is folded in a sequential manner to form a three-dimensional nose-accommodating cutout groove 320 whose width decreases from the rear to the front in accordance with the shape of the nose, forming the anti-fogging wrinkle member 300, and the mask body 100 is formed at the lower end 100-1 of the plate-like member 10. Then, both ends of the anti-fogging wrinkle member 300 are ultrasonically fused to the mask body 100 to manufacture the anti-fogging wrinkle member integrally with the mask body.

[0039] When manufactured in this manner, as shown in FIG. 8, the mask body 100 and the anti-fogging wrinkle member 300 having the nose receiving incision groove 320 can be formed at once using one sheet of plate-like member 10, which has the advantages of being easy to manufacture and mass-produced, thereby reducing production costs; the highest tension is applied to the highest part of the nose part of the mask, but the incision in the nose part distributes the tension applied to the face more evenly, improving the induction of pain; and the mask body 100 and the anti-fogging wrinkle member 300 are made of antibacterial, antiviral and moisture-resistant material in a single piece and can be folded simply, which has the advantages of preventing contamination from small gaps caused by poor seams or separation in advance.

[0040] Here, the plate-shaped member 10 may be made of a polypropylene spunbond nonwoven fabric, a polyester or polypropylene needle punching nonwoven fabric, or the like, similar to the mask body 100.

[0041] In addition, it is preferable that a wire W is embedded in the upper end of the mask body 100. That is, even if the nose contour is contoured by the wire W provided at the upper end of the mask body 100, the wire may separate due to the movement of the facial muscles and the jaw when speaking, but this can be completely blocked by making the wire fit snugly.

[0042] As described above, the present invention has been illustrated and described based on specific embodiments, but it will be readily apparent to anyone skilled in the art that various modifications and changes can be made without departing from the spirit and scope of the invention as defined by the claims.
