Description

Anti-fog glasses mask

[0001] The present invention relates to a mask for preventing fogging of glasses, and more specifically, to a mask for preventing fogging of glasses, which is configured to improve wearing comfort by maintaining a close contact with the nose area when wearing the mask through an anti-fogging wrinkle member integrally formed with the mask body, and to prevent fogging of glasses by blocking the rise of exhaled air.

[0002]

[0003] In general, masks are worn to filter out harmful dust particles such as yellow dust or fine dust mixed in the outside air, as well as germs such as COVID-19, thereby helping to ensure that only harmless air is breathed.

[0004]

[0005] However, since the main body of the conventional mask does not completely seal against the wearer's nose area and there are gaps on both sides of the nose area, dust and harmful substances can enter through these gaps, resulting in a reduced dust-proofing effect.

[0006]

[0007] In addition, when walking or working while wearing glasses, the exhaled air rises upward along the inner surface of the mask body, causing fogging on the mask and glasses, which obstructs the user's vision, causing great inconvenience when walking or working, and many other problems are exposed.

[0008]

[0009] Accordingly, Korean Patent Publication No. 10-2022-0104084 discloses a detachable mask that prevents fogging by installing a double barrier to block air leakage from the upper portion of the mask body.

[0010]

[0011] However, the conventional technology had the problem that the mask body and the double barrier were configured separately, so the double barrier had to be manufactured and then separately bonded to the manufactured mask body, which made the manufacturing process complicated and difficult. In addition, there was the problem that the double barrier was easily separated from the mask body when wearing the mask, reducing the anti-fogging effect. In addition, there was the problem that contaminants could enter the mask due to defective seams or small gaps in separation.

[0012]

[0013] The present invention has been proposed to improve the above-described problems, and its purpose is to provide an improved anti-fogging mask for glasses, which improves the wearing comfort by allowing the anti-fogging wrinkle member to be formed integrally with the mask body, thereby maintaining a close contact with the nose area when the mask is worn, and at the same time, prevents the rise of exhaled air, thereby preventing fogging on glasses.

[0014]

[0015] The above-described object is achieved by a mask for preventing fogging of glasses, which comprises a mask body formed of a plate-like member and worn on the user's face, a pair of hanging bands whose respective ends are ultrasonically fused and joined at both sides of the mask body, and an anti-fogging wrinkle member integrally formed on the inner surface of the upper end of the mask body, in which a plurality of folded wrinkles are formed in a zigzag shape in the vertical direction in cross-section, and an exhalation discharge groove is formed on the lower surface of each of the folded wrinkles, so that when the mask is worn, the rear surface of the anti-fogging wrinkle member is configured to maintain a close contact with the nose and face through a cushion formed in the front-back direction by the folded wrinkles, and at the same time, improve the wearing comfort, and when the wearer breathes, the exhalation gas coming out through the nose or mouth is blocked from rising through the exhalation groove, and the exhalation gas is quickly discharged to the side of the mask body to prevent fogging of glasses.

[0016]

[0017] Here, the mask body and the anti-fogging pleated member are characterized in that the anti-fogging pleated member is manufactured by sequentially folding the upper part of the plate-like member from top to bottom in a zigzag shape to form a plurality of folded pleats in which protrusions and depressions are continuously formed in a zigzag shape, and the mask body is formed in the lower part of the plate-like member, and then both ends of the anti-fogging pleated member are ultrasonically fused to the mask body to form the anti-fogging pleated member integrally with the mask body.

[0018]

[0019] In addition, the anti-fogging wrinkle member is characterized in that a nose-accommodating cut groove is formed in the central portion in the front-back direction to accommodate the nose, so that when the mask is worn, the anti-fogging wrinkle member receives the nose in the nose-accommodating cut groove, and has uniform pressure overall, so that the central portion adheres to the nose area and both sides adhere to the face, so that the mask body does not rise.

[0020]

[0021] And, the mask body and the anti-fogging pleated member are characterized in that a concave, rounded cut portion is formed downward at the central upper end of the plate-like member, the upper end of the plate-like member is sequentially folded from top to bottom in a zigzag shape to form a plurality of folded pleats in which protrusions and depressions are continuously formed in a zigzag shape, and the cut portion is sequentially folded at the central part of the folded pleats to form a three-dimensional nose-accommodating cut groove that narrows from the rear to the front in a width corresponding to the shape of the nose, thereby forming the anti-fogging pleated member, and the mask body is formed at the lower end of the plate-like member, and then both ends of the anti-fogging pleated member are ultrasonically fused to the mask body, so that the anti-fogging pleated member is integrally formed with the mask body.

[0022]

[0023] And, the mask body is characterized in that it is composed of a double layer of inner and outer skins made of non-woven fabric, a filter made of meltblown non-woven fabric placed between the inner and outer skins, and a carbon nano-network interposed between the inner skin, the filter, and the filter and the outer skin, respectively, wherein the inner skin is impregnated with an inner skin impregnation solution made by adding 10 parts by weight of platinum nano, 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 and used, and the outer skin is impregnated with an outer skin impregnation solution made by adding 5 parts by weight of bamboo 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 and used.

[0024]

[0025] The anti-fogging mask according to the present invention has an improved effect in that the mask is maintained in a stable wearing state through an anti-fogging pleated member integrally formed on the inside of the upper part of the mask body, and air ventilated through the upper part of the mask and the wearer's exhaled air do not leak into the glasses, thereby preventing fogging on the glasses.

[0026]

[0027] In addition, the anti-fogging mask according to the present invention has the effect of improving pain induction by applying the greatest amount of tension to the highest part of the nose area of ​​the mask, and making the tension applied to the face more evenly by making an incision in the nose area.

[0028]

[0029] In addition, the anti-fogging mask according to the present invention has the effect of preventing fogging on glasses due to uniform expansion of the folds (unevenness at the fold area) even when breathing heavily forward, such as during exercise or strenuous labor.

[0030]

[0031] In addition, the anti-fogging mask according to the present invention has the effect of preventing contamination due to defective seams or small gaps in separation in advance by simply folding the mask and the anti-fogging pleated member (uneven) into one piece of antibacterial, antiviral, and moisture-proof material.

[0032]

[0033] In addition, the anti-fogging mask according to the present invention has an improved effect of increasing not only cold-proofing but also fine dust penetration resistance through a mask body composed of a double layer of nonwoven fabric, a filter disposed therebetween, and two carbon nano-networks each interposed between the double layer and the filter, and having at least one antibacterial layer to increase resistance to bacteria, thereby contributing to the improvement of the user's health.

[0043]

[0044] The present invention will be described in detail with reference to the attached drawings as follows.

[0045]

[0046] Referring to FIGS. 1 to 3, the anti-fogging mask according to the present invention is characterized in that it can maintain a close contact with the nose area, thereby improving the wearing comfort and preventing the rise of exhaled air, thereby preventing fogging on glasses, and is configured to include a mask body (100), a hanging band (200), and an anti-fogging pleated member (300).

[0047]

[0048] First, the mask body (100) is formed as a plate-shaped member and is worn on the user's face. It is configured to cover the user's mouth and nose to block external air, and is mainly formed of a filter paper having a filtration function. For example, it can be manufactured using a polypropylene spun bond nonwoven fabric, polyester or polypropylene needle punching nonwoven fabric, etc.

[0049]

[0050] That is, the mask body (100) can be manufactured by laminating a polypropylene spun bond nonwoven fabric, a polyester or polypropylene needle punching nonwoven fabric, etc., and then ultrasonically fusing the edges.

[0051]

[0052] Here, it is preferable that the mask body (100) is formed in a plate shape including a plurality of horizontal wrinkles (110), so that the area is expanded in the vertical direction by the wrinkles (110), thereby forming a curved surface corresponding to the user's face when worn.

[0053]

[0054] Next, the hanging band (200) is formed by connecting both ends of the mask body (100) by ultrasonic welding, and supports the mask body (100) against the user's left and right ears, respectively. The hanging band (200) is composed of left and right hanging bands (210, 220), and may be formed as a thin and long string. It is preferable that the hanging band (200) has a ring shape with both ends connected, and it is also preferable that it has some elasticity in the longitudinal direction. However, of course, it is not limited thereto.

[0055]

[0056] Next, the anti-fogging wrinkle member (300) is integrally formed on the upper inner surface of the mask body (100), and is configured such that a plurality of folded wrinkles (310) are formed in a zigzag shape in a vertical direction in cross section, with protrusions (311) and concave portions (312) continuously formed, and an exhalation groove (312) is formed on the lower surface of each of the protrusions (311).

[0057]

[0058] Here, the above-mentioned anti-fogging wrinkle member (300) is formed integrally in the left and right directions on the upper part of the mask body (100) so as to cover the entire upper part of the mask body (100).

[0059]

[0060] Accordingly, as illustrated in FIG. 4, the anti-fogging member (300) is configured to improve the wearing comfort by allowing the rear surface of the anti-fogging wrinkle member (300) to remain in close contact with the nose and face through the cushion formed in the front-back direction by the folding wrinkles (310) when the mask is worn. In addition, the exhalation discharge groove (313) is configured to block the rise of exhaled air coming out through the nose or mouth when the wearer breathes, and to quickly discharge the exhaled air to the side of the mask body (100) to prevent fogging on the glasses.

[0061]

[0062] In addition, the mask body (100) and the anti-fogging wrinkle member (300) formed integrally can be manufactured integrally using a single plate-shaped member (300-1).

[0063]

[0064] To this end, as illustrated in FIGS. 5a to 5c, the mask body (100) and the anti-fogging pleat member (300) are formed by sequentially folding the upper portion (300-1) of the plate-like member (10) from the upper side to the lower side in a zigzag shape to form a plurality of folded pleats (310) in which protrusions (311) and concave portions (312) are continuously formed in a zigzag shape, thereby forming the anti-fogging pleat member (300), and the mask body (100) is formed on the lower portion (100-1) of the plate-like member (10). Then, both ends of the anti-fogging pleat member (300) are ultrasonically fused to the mask body (100) to manufacture the anti-fogging pleat member (300) so that it is integrally formed with the mask body (100).

[0065]

[0066] When manufactured in this way, the mask body (100) and the anti-fogging pleated member (300) can be formed at once through a single sheet of plate-like material (10), so that the manufacturing is easy, mass production is possible, and the cost is reduced, and the mask body (100) and the anti-fogging pleated member (300) are formed as a single sheet of antibacterial, antiviral, and moisture-proof material, so that contamination due to defective seams or small gaps in separation can be prevented in advance.

[0067]

[0068] Meanwhile, according to the present invention, as shown in FIG. 6, it is preferable that the anti-fogging wrinkle member (300) has a nose-accommodating cut groove (320) formed in the central portion to accommodate the nose in the front-back direction.

[0069]

[0070] That is, when the mask is worn, the anti-fogging wrinkle member (300) is configured so that the wearer's nose is accommodated in the nose-accommodating cut groove (320), and the anti-fogging wrinkle member (300) has uniform pressure throughout, so that the central portion is in close contact with the nose area and both sides are in close contact with the face, so that the mask body (100) does not rise from the face.

[0071]

[0072] In addition, the nose receiving incision groove (320) formed in the nose area, which is located at the highest point of the nose part of the mask and is subject to the greatest amount of tension, makes the tension applied to the face more even, thereby improving pain relief.

[0073]

[0074] Additionally, even when breathing heavily, such as during exercise or strenuous labor, the glasses do not fog up due to the uniform expansion of the folds (the unevenness of the fold area).

[0075]

[0076] Accordingly, the mask body (100) can be kept in close contact with the nose and facial area through the anti-fogging wrinkle member (300), thereby improving the wearing comfort and reliably blocking the rise of exhaled air.

[0077]

[0078] Meanwhile, the mask body (100) and the anti-fogging wrinkle member (300) in which the nose-receiving incision groove (320) is formed can also be manufactured using a single plate-shaped member (10).

[0079]

[0080] To this end, as illustrated in FIGS. 7a to 7c, a concave, rounded cut (320-1) is formed at the upper center of the plate-like member (10), and the upper end (300-1) of the plate-like member (10) is sequentially folded from the upper side to the lower side in a zigzag shape to form a plurality of folded wrinkles (310) in which protrusions (311) and concave parts (312) are continuously formed in a zigzag shape, and as the cut (320-1) is sequentially folded at the central portion of the folded wrinkles (310), a three-dimensional nose-accommodating cut groove (20) is formed that narrows from the rear to the front in a width corresponding to the shape of the nose, thereby forming an anti-fogging wrinkle member (300), and a mask body (100) is formed at the lower end (100-1) of the plate-like member (10). Next, the two ends of the anti-fogging wrinkle member (300) are ultrasonically bonded to the mask body (100) so that the anti-fogging wrinkle member is integrally formed with the mask body.

[0081]

[0082] When manufactured in this way, as illustrated in FIG. 8, the mask body (100) and the anti-fogging pleated member (300) with the nose-accommodating incision groove (320) can be formed at once through a single plate-like member (10), so that the manufacturing is easy, mass production is possible, and there is an advantage of reducing the cost. In addition, the highest tension is applied to the highest part of the nose part of the mask, and the tension applied to the face is made more even through the nose-accommodating incision, thereby improving the induction of pain. In addition, the mask body (100) and the anti-fogging pleated member (300) are formed as one piece of antibacterial, antiviral, and moisture-proof material, so that contamination due to defective seams or small gaps can be prevented in advance.

[0083]

[0084] Here, the plate-shaped member (10) may be made of a polypropylene spunbond nonwoven fabric, polyester or polypropylene needle punching nonwoven fabric, similar to the mask body (100).

[0085]

[0086] In addition, it is preferable that a wire (W) be built into the upper part of the mask body (100). That is, even if the nose is outlined with the wire (W) installed at the upper part of the mask body (100), the wire creates a gap due to the movement of the facial muscles and the movement of the jaw while speaking, and this can be blocked by fluidly and perfectly fitting it.

[0087]

[0088] Although the present invention has been illustrated and described with reference to specific embodiments as described above, 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.
