Description

[Technical field]

[0001] This application claims the benefit of priority based on Korean Patent Application No. 2021-0045430 dated April 7, 2021, and all contents disclosed in the documents of that Korean patent application are incorporated as part of this specification.

[0002] The present invention relates to a mask filter including a bonding part, and more particularly to a mask filter having a detachable bonding part added to a part of the mask filter. [Background technology]

[0003] Masks have been used in a limited way as a product related to diseases. They are used as a supplementary measure to prevent the spread of a disease to others and to prevent infection from others. The use of masks due to yellow sand and fine dust is increasing, but this is also for the purpose of preventing diseases.

[0004] The COVID-19 pandemic has caused a sudden change in perception of masks. Demand has exploded to the point where masks have become scarce, and society has learned that masks alone have a significant effect in preventing disease. People have also widely shared their experiences of spending most of the day wearing masks. The negative image of hiding one's face by wearing a mask has faded in both the East and the West.

[0005] After that, masks were positioned as a daily necessity like glasses. It is thought that every household now has more than a minimum number of masks on hand. It will become very natural to wear a mask to protect against pollen and yellow dust in spring, automobile fumes in summer, and mild colds in winter. Just as wearing glasses is not strange at all, wearing a mask will also become a very natural part of our culture.

[0006] Masks are classified into grades and uses according to their leakage rate. The leakage rate of masks used in Korea is measured according to the leakage rate test method described in Guide No. 0349-04 of the Korea Food and Drug Safety Assessment Agency's "Guidelines for Standard Specifications of Health Masks (Petitioner's Guide)."

[0007] Even if a mask has an approved leakage rate, the actual leakage rate may vary depending on the face size of the user wearing it and the length of the straps that secure it to the ears.

[0008] In a preliminary study, the inventor of the present invention used a mask made for adults and compared the leakage rate when the length of the mask strings was not adjusted and when the length including the mask strings was adjusted to 120% of the face length. It was found that the latter case reduced the leakage rate by at least 25% and often up to 83% compared to the former case. In other words, it can be seen that the leakage rate of a mask can only be reduced by adjusting the length of the strings, thereby achieving the original purpose of wearing a mask. The face length referred to here is the face length measured using Morpheus, and refers to the distance from the user's left ear to the bottom of the nose, and from the bottom of the nose to the right ear.

[0009] The length of the mask string can be adjusted to increase the leakage rate, but the mask designed according to the curvature of the face, or more precisely, the size of the mask filter, also affects the leakage rate. Although the size of the face varies depending on the age and gender, it is practically impossible to provide a customized mask filter that fits each individual user. Currently, masks on the market are only provided with mask filters of several pre-defined sizes or mask filters with many curves. Summary of the Invention [Problem to be solved by the invention]

[0010] As described above, the present invention is intended to solve the problems of the conventional art, and has an object to provide a mask filter that can be adjusted in size by the user to accommodate the face sizes of people of all ages and genders.

[0011] Non-limiting examples of the mask include a double folding mask, a foldable mask, a cup-type mask, and a splash mask.

[0012] The mask filter referred to throughout the specification of the present invention generally corresponds to the mask body excluding the string portion, and the present invention refers to this portion as the mask filter or filter. [Means for solving the problem]

[0013] In order to solve the above problems, the present invention provides a mask filter including: a filter body disposed in front of a user's face; an upper filter surface which is fixed along at least a part of an upper outer periphery of the filter body, or fixed spaced downward from at least a part of the upper outer periphery of the filter body, or an upper part of the filter body is bent to cover at least a part of the skin of the user's nose and the surrounding area; and a lower filter surface which is fixed along at least a part of a lower outer periphery of the filter body, or fixed spaced upward from at least a part of the lower outer periphery of the filter body, or a lower surface of the filter body is bent to cover at least a part of the skin of the user's chin and the surrounding area, wherein both sides of at least one of the upper filter surface and the lower filter surface are provided with one or more first attachment parts further attached to the filter body, and the first attachment parts are in a separable attachment form.

[0014] The present invention also provides a mask filter including: a filter body disposed on the front of a user's face; an upper filter surface that is fixed along at least a part of an upper outer periphery of the filter body, or fixed spaced apart downward from at least a part of the upper outer periphery of the filter body, or an upper part of the filter body is bent to cover at least a part of the skin of the user's nose and the surrounding area; and a lower filter surface that is fixed along at least a part of a lower outer periphery of the filter body, or fixed spaced apart upward from at least a part of the lower outer periphery of the filter body, or a lower surface of the filter body is bent to cover at least a part of the skin of the user's chin and the surrounding area, wherein at least one of the upper filter surface and the lower filter surface has one or more second attachment parts further attached to the filter body in a center thereof, and the second attachment parts are in a separable attachment form.

[0015] The present invention also provides a mask filter including a filter body that is placed in front of a user's face and has a folded center, the filter body includes a joint where one side end of a symmetrical left body part and a symmetrical right body part are fused to each other while overlapping each other, and a third joint part in an additional separable form of joint is added to at least one of the upper and lower parts of the filter body around the joint part. In this case, the third joint part may be in a form where the left body part and the right body part are joined separately from the joint part, or the upper or lower part of the filter body is joined while overlapping each other.

[0016] The present invention also provides a mask filter including a filter body that is placed in front of a user's face and has a horizontally foldable portion, wherein at least one of the upper left end, lower left end, upper right end, and lower right end of the filter body is provided with one or more fourth attachment parts that can connect the filter bodies together, and the fourth attachment parts are in a separable connection form.

[0017] The extent to which the upper and lower surfaces of the filter extend from the filter body varies depending on whether the first and / or second bonding parts according to the present invention are connected, which allows for compatibility with various face sizes. Also, the effective size of the filter body varies depending on whether the third and fourth bonding parts according to the present invention are connected, which allows for compatibility with various face sizes.

[0018] The first to fourth attached parts are detachable by the user, and the user can separate a desired part of the first to fourth attached parts to fit the size of his or her face.

[0019] Non-limiting examples of the separable bonding form may be at least one selected from the group including fusion bonding having a peel strength of 500 (g / 25 mm) or less based on SUS standards at 90 degrees, hook-and-loop fasteners, snap buttons, fitting, clips, magnetic forces, sewing, buttons, couplers, scissors, adhesives, cohesive forces, and elastic bonding.

[0020] The first and second bonding portions on the upper and lower surfaces of the filter may be disposed along the outer periphery of the upper and lower surfaces of the filter, respectively, and the third and fourth bonding portions may also be disposed along the outer periphery of the filter body.

[0021] Wrinkles may be formed around each of the first to fourth attached parts.

[0022] Furthermore, the present invention can be provided in various combinations of possible forms among the various solution means described above. Effect of the Invention

[0023] The present invention provides a single mask filter with a bonding part, and by adjusting the separation of the bonding part, it can be adapted to the face of each user, so that it is possible to provide a mask filter with excellent leakage rate and wearing comfort. In addition, the process of adding the bonding part can be performed by applying the conventional process as it is and only modifying a part, so that the addition of the above configuration is easy and economical. Meanwhile, since it is not necessary to provide mask filters of various sizes according to the size and shape of the user's face, there is a low possibility of surplus products due to the production of a small variety of products. This is also very favorable from an environmental perspective, as it makes resource utilization more efficient and reduces the rapidly increasing amount of mask filter waste.

[0027] The present invention will be described in more detail below using examples. However, these examples are for illustrative purposes only and the scope of the present invention is not limited to these examples. The examples of the present invention will be described below with reference to the drawings.

[0028] FIG. 1 is a perspective view showing a conventional double folding mask, FIG. 2 is an example of a first attachment part according to the present invention, and FIG. 3 is an example of a second attachment part according to the present invention.

[0029] 1 to 3, the double folding mask 100, 200 includes a filter body 110, 210 disposed on the front of a user's face, a filter upper surface 120, 220 that is fixed along at least a part of an upper outer periphery of the filter body 110, 210, or fixed spaced apart downward from at least a part of an upper outer periphery of the filter body 110, 210, or an upper portion of the filter body 110, 210 is bent to cover at least a part of the user's nose and the skin around it, and a filter lower surface 130, 230 that is fixed along at least a part of a lower outer periphery of the filter body 110, 210, or fixed spaced apart upward from at least a part of a lower outer periphery of the filter body 110, 210, or a lower surface of the filter body 110, 210 is bent to cover at least a part of the user's chin and the skin around it. The filter bodies 110, 210, the filter upper surfaces 120, 220, and the filter lower surfaces 130, 230 constitute a mask filter.

[0030] The filter upper surface 120, 220 may further include a nose fixing portion 125, 225 for increasing the fixing force with the nose.

[0031] The mask filter is attached with strings 140, 240 to form the double folding mask 100, 200, which is the mask we use. The filter body 110, 210 is made by stacking and bonding multiple porous substrates in multiple layers. The joints 111, 211 of the filter body 110, 210 are the sites where multiple porous substrates are bonded. The filter upper surface 120, 220 and the filter lower surface 130, 230 are also manufactured in a similar process, and the same joints are formed along the outer periphery.

[0032] Filter body 110,210 also includes a lace joint 114,214 to which laces 140,240 are attached.

[0033] The filter bodies 110, 210 and the filter upper surfaces 120, 220, and the filter bodies 110, 210 and the filter lower surfaces 130, 230 are respectively joined along upper surface joining parts 112, 212 and lower surface joining parts 113, 213. In Figs. 1 to 3, the filter upper surfaces 120, 220 are fixed to at least a portion of the upper outer periphery of the filter bodies 110, 210 at a distance downward, and the filter lower surfaces 130, 230 are fixed to at least a portion of the lower outer periphery of the filter bodies 110, 210 at a distance upward.

[0034] Referring to FIG. 2, the mask filter according to the present invention provides a mask filter having one or more first attachment parts A-A', B-B', C-C', D-D' which are further attached to the filter body 210 on both sides of at least one of the filter upper surface 220 and the filter lower surface 230, and the first attachment parts A-A', B-B', C-C', D-D' are in a detachable attachment form.

[0035] Referring to FIG. 3, the mask filter according to the present invention provides a mask filter having one or more second attachment parts E-E', F-F' further attached to the filter body 210 at the center of at least one of the filter upper surface 220 and the filter lower surface 230, and the second attachment parts E-E', F-F' are in a detachable attachment form.

[0036] 2 and 3 are schematic diagrams of only the double folding mask filter, and the part for fixing it to the face is omitted. In the present invention, in addition to the parts fused when manufacturing a conventional double folding mask filter, a first binding part in which one or more of the corresponding positions of A-A', B-B', C-C', and D-D' are bound, or a second binding part in which one or more of the corresponding positions of E-E' and F-F' are bound, is added. When the first binding parts A-A', B-B', C-C', and D-D' and the second binding parts E-E' and F-F' are bound, they may be bound to other positions instead of being mutually symmetrical positions. When the first binding parts A-A', B-B', C-C', and D-D' and the second binding parts E-E' and F-F' are bound, additional bindings in addition to paired bindings are possible, which can accommodate various face sizes of users. When the face is smallest, the first bonding portions A-A', B-B', C-C', D-D' or the second bonding portions E-E', F-F' are not bonded, and the larger the face is, the more bonds there are.

[0037] The filter body 210 according to the present invention is placed around the mouth of a user, the filter upper surface 220 is placed around the nose of the user, and the filter lower surface 230 is placed around the chin of the user.

[0038] Both sides of the filter upper surface 220 and the filter lower surface 230 are provided with one or more first connecting parts (connecting parts corresponding to A-A', B-B', C-C', and D-D', respectively) that are fixed to the filter body 210, and the first connecting parts (connecting parts corresponding to A-A', B-B', C-C', and D-D', respectively) may be in a detachable connecting form.

[0039] One or more second connecting parts (connecting parts corresponding to E-E', F-F') fixed to the filter body 210 are provided at the center of the filter upper surface 220 and the filter lower surface 230, and the second connecting parts (connecting parts corresponding to E-E', F-F') may be in a detachable connecting form.

[0040] 2 and 3, the separable connection form must have a strength sufficient to separate the filter body 210 from the upper filter surface 220 and the lower filter surface 230 without damage. For example, the peel strength of one connection is 500 (g / 25mm) or less based on 90 degrees SUS standard. Further, other separable connection forms may be at least one selected from the group including hook-and-loop fasteners, snap buttons, fitting, clips, magnetic forces, sewing, buttons, couplers, scissors, adhesives, cohesive, and elastic connections. The range in which the upper filter surface can be disposed may be from the most protruding point of the tip of the nose to the lower end of the nasal bone. The manner in which the third and fourth connecting parts are connected may be the same as that of the first and second connecting parts.

[0041] In FIG. 2 or FIG. 3, examples of possible binding sites are shown as A-A', B-B', C-C', D-D', E-E', and F-F', respectively. A, B, C, D, E, and F are shown as multiple points, at least one of which can be a binding site. The binding sites of A, B, C, D, E, and F bind to the corresponding A', B', C', D', E', and F', respectively. When binding A-A', B-B', C-C', D-D', E-E', and F-F', they may bind to other sites instead of the mutually symmetric positions.

[0042] A, B, C, and D are examples of the first attached part, and E and F are examples of the second attached part. When the filter is manufactured, A, B, C, D, E, and F can be initially manufactured in a state where they are all attached. Later, the user can separate the attached parts and adjust them to fit their face.

[0043] The extent to which the upper and lower surfaces of the filter spread from the filter body varies depending on whether the first and / or second attachment parts according to the present invention are attached, and this can accommodate various face sizes. The first and / or second attachment parts can be separated by the user, so that the user can separate the desired parts of the first and / or second attachment parts to fit their own face size. This also applies to the third and fourth attachment parts described below.

[0044] When the first and second bonding parts are arranged along the outer periphery of the filter upper surface 220 and the filter lower surface 230, the strength of the adhesion is strong, so that a part of the filter upper surface 220 or the filter lower surface 230 may be damaged when separated, but this is not a problem. In this case, the damaged filter upper surface 220 or the filter lower surface 230 is the part arranged on the outermost side, so the remaining part can be in close contact with the user's face. In this case, among the examples of the first bonding parts A-A', B-B', C-C', and D-D' and the second bonding parts E-E' and F-F', the bonding parts arranged along the outer periphery of the filter upper surface 220 and the filter lower surface 230 correspond to the bonding parts.

[0045] Corresponding to the positions of the first to fourth bonding parts, separate wrinkles may be formed in advance on the filter upper surface 220, the filter lower surface 230, or the filter body 210, 410, 610. The wrinkles may be curved rather than straight, following the facial contour, particularly the jawline.

[0046] FIG. 4 is a perspective view showing a conventional foldable mask, and FIG. 5 is an example of a third attachment part according to the present invention.

[0047] 4 and 5, the foldable mask 300, 400 is a mask filter that is placed in front of the user's face and includes a filter body 310, 410 that is folded at the center. The filter body 310, 410 includes a joint portion 311, 411 in which one side end is fused to each other while a symmetrical left body portion 314, 414 and a right body portion 316 are overlapped.

[0048] Referring to FIG. 5, third connecting parts G and H having an additional detachable connecting form are added to at least one of the upper and lower parts of the filter body 410 in the periphery of the joint part 411 .

[0049] In this case, the third connecting parts G and H may be formed by connecting the left body part 414 and the right body part separately from the joining part 411, or by overlapping and connecting the upper or lower parts of the filter body 410.

[0050] FIG. 6 is a perspective view showing a conventional splash prevention mask, and FIG. 7 shows an example of the fourth attachment part according to the present invention.

[0051] 6 and 7, the splash prevention masks 500, 600 are mask filters that are placed in front of the user's face and include a filter body 510, 610 to which a horizontally folded portion is added.

[0052] 7, at least one of the upper left end, lower left end, upper right end, and lower right end of the filter body 610 is provided with one or more fourth connecting parts I and J that can connect the filter bodies to each other, and the fourth connecting parts I and J are in a separable connecting form to provide a mask filter. The fourth connecting part I connects one or more of the fourth connecting parts I to each other, and the fourth connecting part J connects one or more of the fourth connecting parts J to each other.
