Description

Technical Field

[0001] This application relates to the field of face masks, and in particular to a 3D three-dimensional face mask. Background Technology

[0002] Everyday face masks can be mainly divided into two categories based on their shape and function: flat masks and three-dimensional masks. Flat masks are simple to manufacture and have low cost, but their fit to the face is limited. Three-dimensional masks, on the other hand, adapt better to the contours of the face through their three-dimensional structure, creating ample space around the mouth and nose, which improves both wearing comfort and protective effect.

[0003] Existing 3D masks typically employ a multi-layered composite structure, usually consisting of an outer waterproof non-woven fabric layer, a middle meltblown filter layer, and an inner skin-friendly non-woven fabric layer. The common manufacturing process involves yarn sewing, usually achieved by stitching together multiple cut pieces, with sewing thread used to secure the mask's faceplate, nose bridge strip, and other components. This type of 3D mask offers a stable structure and good shape retention.

[0004] However, these sewn 3D masks have the following drawbacks: First, the yarn used for sewing is usually made of chemical fibers such as polyester or nylon, which are relatively hard and prone to roughness and breakage. Direct contact with the skin can easily cause friction irritation or allergic reactions, resulting in poor comfort during long-term wear. Furthermore, the stitching reduces the 3D texture of the mask. Second, 3D masks often use multiple layers of materials, limiting overall breathability and making it difficult for humid and hot air to escape. This can lead to a stuffy feeling when wearing them. The dense stitching further restricts the expansion and contraction of the mask material and airflow, exacerbating localized poor ventilation and discomfort, further reducing the comfort of wearing 3D masks and their suitability for use in different environments and occasions. Utility Model Content

[0005] To address the issues of existing 3D masks having seams that easily irritate the skin, poor breathability, and reduced wearing comfort, 3D texture, and suitability for different environments and occasions, this application provides a 3D 3D mask.

[0006] This application provides a 3D stereoscopic mask, which adopts the following technical solution: A 3D three-dimensional mask includes a mask body, which comprises a surface layer, a breathable middle layer, and an inner layer arranged sequentially from the outer surface to the inner surface. The surface layer, the breathable middle layer, and the inner layer are integrally molded. The mask body has a 3D three-dimensional structure. The mask body has a supporting three-dimensional structure corresponding to the outer contour area and nose bridge area of ​​the face. The supporting three-dimensional structure is used to support the mask body and form a three-dimensional support space. The mask body has a breathable structure corresponding to the mouth and nose area and / or cheek area of ​​the face. The mask body has a supporting structure corresponding to the cheekbone area of ​​the face.

[0007] By adopting the above technical solution, the outer layer, breathable middle layer, and inner layer of the mask body are integrally molded, avoiding the friction and irritation of the skin caused by the sewing threads during the sewing process, and improving the long-term wearing comfort of the mask. The supportive three-dimensional structure can better adapt to the contours of the face, forming ample space at the mouth and nose, improving the three-dimensional texture, wearing comfort, and protective effect of the mask, while also providing some breathing space and reducing stuffiness. The breathable structure in the mouth and nose area and / or cheek area can improve the breathability of the mask, further expelling humid and hot air and reducing stuffiness. The supportive structure in the cheekbone area can further improve the three-dimensional support of the mask for the face, improve the fit and comfort of the mask, and avoid the problem of pressure marks and discomfort caused by direct contact between the high cheekbone area and the edge of the mask. The 3D three-dimensional mask of this application solves the problems of skin irritation and poor breathability caused by the sewing threads of existing three-dimensional masks. The 3D three-dimensional mask is relatively thin and light overall, improving long-term wearing comfort, breathability, and three-dimensional texture, and is suitable for different seasons and occasions with different functional requirements.

[0008] Preferably, the support structure includes an arc-shaped support strip, the arc-shaped opening of which is positioned corresponding to the cheek area of ​​the face.

[0009] By adopting the above technical solution, the arc-shaped opening of the arc-shaped support strip is set to correspond to the cheek area of ​​the face, which can better fit the facial contour, enhance the fit between the mask and the face, and provide stable support for the mask, so that the mask is not easily deformed during wearing, maintains a good three-dimensional shape, and improves the three-dimensional texture and wearing stability of the mask; at the same time, it can also reduce the pressure of the mask on the higher position of the cheekbone area of ​​the face.

[0010] Preferably, the breathable middle layer includes a first breathable layer, a first support layer, and a second breathable layer, which are attached together. The first breathable layer, the first support layer, and the second breathable layer are provided with a plurality of breathable holes in the mouth and nose areas of the face.

[0011] By adopting the above technical solution, the breathable middle layer is composed of a first breathable layer, a first support layer, and a second breathable layer bonded together. The ventilation holes opened in the first and second breathable layers corresponding to the mouth and nose areas of the face can effectively expel hot and humid air. At the same time, the first support layer can play a supporting role to ensure the three-dimensional shape of the mask. The three-layer structure works together to enhance the breathability of the mask, ensure the stability of the mask structure, and improve the performance and wearing comfort of the mask.

[0012] Preferably, the first support layer has a first hollow area on each cheek area corresponding to the face, and the middle area and edge area of ​​the first support layer form a three-dimensional support structure corresponding to the face. The area of ​​the first support layer is smaller than the area of ​​the first breathable layer and the second breathable layer.

[0013] By adopting the above technical solution, a first hollow area is opened in the first support layer corresponding to the cheek areas on both sides of the face, which can enhance the breathability of the cheek area; the middle and edge areas of the first support layer form a three-dimensional support structure on the face, while the edge area of ​​the first breathable layer forms a structure similar to a "bracket", which can support the mask body and form a three-dimensional support space, improving the three-dimensional texture after integral molding; the area of ​​the first support layer is smaller than the area of ​​the first and second breathable layers, which can further reduce the obstruction of air circulation and further improve breathability, so that the middle and edge areas of the breathable middle layer form a thickness difference, which can make the mask relatively thin while having a good three-dimensional feel, further improving the long-term wearing comfort, breathability and three-dimensional texture of the three-dimensional mask.

[0014] Preferably, the support structure is disposed between the first breathable layer and the second breathable layer, and is correspondingly disposed on the top region of the first support layer.

[0015] By adopting the above technical solution, the support structure is set between the first breathable layer and the second breathable layer, and correspondingly set on the top area of ​​the first support layer. The first and second breathable layers can fix and protect the support structure, so that the support structure can be better integrated with the breathable middle layer and enhance the three-dimensionality of the mask.

[0016] Preferably, the breathable middle layer is a sandwich fabric layer.

[0017] By adopting the above technical solution, the sandwich fabric layer has a porous breathable structure with good breathability and elasticity. As a breathable middle layer, it can effectively expel hot and humid air, solving the problem of poor breathability of existing three-dimensional masks. At the same time, the sandwich fabric layer is a one-piece molded fabric layer, which is easy to cut and process during the manufacturing process.

[0018] Preferably, the surface layer has a second hollow area corresponding to the mouth, nose and cheek areas of the face, and the surface layer is attached to the breathable middle layer by a first adhesive layer.

[0019] By adopting the above technical solution, the setting of the second hollow area can enhance the breathability of the mask in the mouth, nose and cheek areas, so that the mouth, nose and cheek areas of the mask corresponding to the face and other edge areas form a thickness difference. While improving the breathability and thinness of the mask, the edge area can form a structure similar to a "support", which plays a good supporting role for the mask. In this way, while improving the breathability and thinness of the mask, the three-dimensional texture of the mask is also improved.

[0020] Preferably, the inner layer has a third hollow area on each side of the cheek area corresponding to the face, and the middle area and edge area of ​​the inner layer form a supporting three-dimensional structure corresponding to the face. The inner layer is attached to the breathable middle layer by a second adhesive layer.

[0021] By adopting the above technical solution, the third hollow area in the inner layer corresponding to the cheek area can increase the breathability of the mask in the cheek area. The three-dimensional support structure formed by the middle and edge areas of the inner layer can provide support for the face, ensure the three-dimensional shape of the mask, and improve the long-term wearing comfort, breathability and three-dimensional texture of the mask.

[0022] Preferably, the support structure is disposed in the inner top region of the inner layer.

[0023] By adopting the above technical solution, the support structure is set in the inner top area of ​​the inner layer, which can provide support for the cheekbone area of ​​the face corresponding to the mask, so that the mask fits the facial contour better and enhances the three-dimensional texture of the mask.

[0024] Preferably, the support structure includes a second support layer and a third support layer sequentially bonded from the outer surface to the inner surface. The area of ​​the third support layer is larger than the area of ​​the second support layer. The second support layer and the inner layer are bonded together by a third adhesive layer, and the third support layer and the second support layer are bonded together by a fourth adhesive layer.

[0025] By adopting the above technical solution, the second and third support layers are bonded together to form a support structure, which can support the cheekbone area of ​​the face corresponding to the mask, ensuring the three-dimensional shape of the mask and enhancing its three-dimensional texture. Furthermore, the area of ​​the third support layer is larger than that of the second support layer, allowing the second support layer to be encased within the third support layer to form a buffer structure, providing better support and cushioning. This further improves the support structure's stability and comfort, reduces pressure on the cheekbone area, and prevents pressure marks and discomfort. The third adhesive layer serves to bond the second support layer and the inner layer, ensuring a stable fit for the second support layer. The fourth adhesive layer serves to bond the third support layer and the second support layer, ensuring a stable fit for the third support layer.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The 3D three-dimensional mask of this application features a 3D three-dimensional structure formed by integral molding of the outer layer, breathable middle layer, and inner layer of the mask body, eliminating the use of stitching and solving the problem of stitching irritating the skin. Supporting three-dimensional structures are provided in the outer contour area of ​​the face and the bridge of the nose to support the mask body and form a three-dimensional support space. Breathable structures are provided in the mouth and nose area and / or cheek area to ensure breathability, solving the problem of poor breathability in three-dimensional masks. The support structure in the cheekbone area further enhances the three-dimensional support of the mask for the face, improving the fit and comfort of the mask, while avoiding pressure marks and discomfort caused by direct contact between the cheekbone area and the mask edge. The 3D three-dimensional mask of this application solves the problems of skin irritation and poor breathability caused by stitching in existing three-dimensional masks. The 3D three-dimensional mask is relatively thin and light overall, improving long-term wearing comfort, breathability, and three-dimensional texture, making it suitable for different seasons and occasions with different functional requirements.

[0027] 2. The arc-shaped support strips of the support structure are set with arc-shaped openings corresponding to the cheek area, which can better fit the face; the first breathable layer, the first support layer and the second breathable layer of the breathable middle layer are attached together, and the first and second breathable layers have ventilation holes corresponding to the mouth and nose area. The first support layer has a first hollow area corresponding to the cheek areas on both sides. The middle part of the first breathable layer forms a support three-dimensional structure corresponding to the bridge of the nose area. The area of ​​the first support layer is smaller than the area of ​​the first and second breathable layers. The support structure is set between the first and second breathable layers and corresponds to the top area of ​​the first support layer. The 3D three-dimensional mask formed in this way has good three-dimensional support and breathability.

[0028] 3. The breathable middle layer is a sandwich fabric layer. The outer layer has a second hollow area corresponding to the mouth, nose and cheek areas and is bonded to the breathable middle layer through the first adhesive layer. The inner layer has a third hollow area corresponding to the two cheek areas and forms a supporting three-dimensional structure in the middle corresponding to the bridge of the nose area. The inner layer is bonded to the breathable middle layer through the second adhesive layer. The support structure is set in the top area of ​​the inner side of the inner layer and is composed of a second support layer and a third support layer bonded together. The area of ​​the third support layer is larger than that of the second support layer. The two are bonded together through the third adhesive layer and the fourth adhesive layer, respectively, which further optimizes the breathability and support performance of the 3D three-dimensional mask.

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] Example 1 Example 1 discloses a 3D stereoscopic mask.

[0038] Reference Figures 1-3A 3D three-dimensional mask includes a mask body, which comprises an outer layer 1, a breathable middle layer 2, and an inner layer 3. The outer layer 1, breathable middle layer 2, and inner layer 3 are integrally molded, and the mask body has a 3D three-dimensional structure. Preferably, the outer layer 1 is made of cotton, modal, spandex, or a blended fabric, or it can be a functional fabric with UV protection, etc. In this embodiment, the outer layer 1 is a blended fabric of spandex and nylon with UV protection, with a nylon content of 75wt% and a spandex content of 25wt%. The breathable middle layer 2 is made of cotton, which has good softness and comfort. The inner layer 3 can be made of Tencel, spandex, modal, or a blended fabric, or it can be a fabric with cooling function. In this embodiment, the inner layer 3 is a blended fabric of spandex and nylon with cooling function, with a nylon content of 70wt% and a spandex content of 30wt%.

[0039] Reference Figure 3 The mask body has a supporting three-dimensional structure corresponding to the outer contour area and nose bridge area of ​​the face. The supporting three-dimensional structure supports the mask body and forms a three-dimensional support space. The mask body has a breathable structure corresponding to the mouth and nose area and / or cheek area of ​​the face, which provides good breathability. Specifically, in this embodiment, the outer layer 1 and the breathable middle layer 2 are bonded together by a first adhesive layer 4, and the inner layer 3 and the breathable middle layer 2 are bonded together by a second adhesive layer 5. The first adhesive layer 4 and the second adhesive layer 5 are preferably polyurethane hot melt adhesive films, which have good bonding stability and environmental friendliness. The breathable middle layer 2 includes a first breathable layer 21, a first support layer 22 and a second breathable layer 23, which are bonded together. Preferably, the first breathable layer 21, the first support layer 22 and the second breathable layer 23 are bonded together. The second breathable layer 23 is made of cotton, which has good comfort and breathability. The first breathable layer 21 and the second breathable layer 23 are provided with a number of air holes 211 in the mouth and nose area of ​​the face. The first support layer 22 is provided with a first hollow area 221 in the cheek area on both sides of the face, so that the first support layer 22 forms a support three-dimensional structure with two first hollow areas 221. The first hollow area 221, together with the number of air holes 211 of the first breathable layer 21 and the number of air holes 211 of the second breathable layer 23, form a breathable structure.

[0040] Continue to refer to Figure 3More specifically, the area of ​​the first support layer 22 is smaller than the area of ​​the first breathable layer 21 and the area of ​​the second breathable layer 23, so that the first support layer 22 is disposed in the inner area of ​​the first breathable layer 21 and the second breathable layer 23. The outer edge area of ​​the breathable middle layer 2 and the corresponding area of ​​the two cheeks are relatively thin, and the area of ​​the breathable middle layer 2 corresponding to the first support layer 22 forms a support three-dimensional structure, further improving the three-dimensional support of the entire 3D three-dimensional mask. The mask body has support structures 6 on both sides of the cheekbone area corresponding to the face. The support structures 6 are located between the first breathable layer 21 and the second breathable layer 23, and are located on the top area of ​​the first support layer 22, so that the support structures 6 are stably fixed. Specifically, the support structure 6 includes an arc-shaped support strip, the arc of which is set to the cheek area of ​​the face. The thickness of the arc-shaped support strip is 0.5-2mm. Preferably, the thickness of the arc-shaped support strip can be 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm and 2mm. In this embodiment, the thickness of the arc-shaped support strip is 1mm. The width of the arc-shaped support strip is 4-12mm. Preferably, the width of the arc-shaped support strip can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm and 12mm. In this embodiment, the width of the arc-shaped strip is 8mm. The support structure 6 can support the cheekbone area, further improving the three-dimensional support and wearing comfort of the 3D mask.

[0041] The implementation principle of Example 1 is as follows: the outer layer 1, the first adhesive layer 4, the first breathable layer 21, the first support layer 22, the support structure 6, the second breathable layer 23, the second adhesive layer 5, and the inner layer 3 are cut to size and stacked sequentially. Then, they are molded using an integrated molding machine to obtain a 3D three-dimensional mask. No sewing is used during the entire preparation process, avoiding the irritation of facial skin caused by sewing threads. The first support layer 22 serves as the "support" structure of the 3D three-dimensional mask, enhancing its three-dimensional support. The ventilation holes 211 of the first and second breathable layers 21 and 23, in conjunction with the first support layer 22, form a breathable structure. The support structure 6 provides support for the cheekbone area of ​​the face, further improving the three-dimensional support and wearing comfort of the 3D three-dimensional mask.

[0042] Example 2 The difference between Example 2 and Example 1 is that Example 2 discloses a 3D stereoscopic mask with a different structure than Example 1, referring to... Figures 4-6The breathable middle layer 2 is a sandwich fabric layer. The outer layer 1 has a second hollow area 11 corresponding to the mouth, nose and cheek areas of the face. The outer layer 1 is attached to the breathable middle layer 2 by the first adhesive layer 4. The inner layer 3 has a third hollow area 31 corresponding to both cheek areas of the face. The middle area and edge area of ​​the inner layer 3 form a supporting three-dimensional structure corresponding to the face. The inner layer 3 is attached to the breathable middle layer 2 by the second adhesive layer 5. The support structure 6 is set in the inner top area of ​​the inner layer 3. The support structure 6 includes a second support layer 61 and a third support layer 62 attached sequentially from the outer surface to the inner surface. The area of ​​the third support layer 62 is larger than the area of ​​the second support layer 61. The second support layer 61 and the inner layer 3 are attached by the third adhesive layer 63. The third support layer 62 and the second support layer 61 are attached by the fourth adhesive layer 64. The rest is the same as in Example 1.

[0043] The implementation principle of Example 2 is as follows: The outer layer 1, first adhesive layer 4, breathable middle layer 2, second adhesive layer 5, inner layer 3, third adhesive layer 63, second support layer 61, fourth adhesive layer 64, and third support layer 62 are cut to size and stacked sequentially. Then, they are molded using an integrated molding machine to obtain a 3D three-dimensional mask. No sewing is used during the entire preparation process, avoiding the irritation of facial skin caused by sewing threads. The central and edge areas of the inner layer 3 form a supporting three-dimensional structure corresponding to the face. The second hollow area 11 of the outer layer 1 and the third hollow area 31 of the inner layer 3 improve the breathability of the 3D three-dimensional mask, thus forming a lightweight and breathable 3D three-dimensional mask. This structure is thinner and lighter than the 3D three-dimensional mask of Example 1.
