Description

Mask structure with nose pad Technical Field

[0001] This invention relates to a structure, particularly a mask structure with a nose pad. Background Technology

[0002] The convenience brought by industrial development has led more and more countries around the world to enter industrialized societies. However, the ensuing problems include environmental pollution such as air pollution, especially the health problems caused by air pollution.

[0003] People need to breathe air every day. If there are too many harmful substances in the air, they can cause damage to the human respiratory organs after being inhaled. According to the World Health Organization's 2009 report "Global Health Risks," urban outdoor air pollution was listed as the fourteenth risk factor for death worldwide in 2004.

[0004] Air pollution has many potential health effects, ranging from subtle physiological changes to obvious symptoms such as itchy nose and throat, wheezing, coughing, chest pain or tightness. For patients with pre-existing respiratory conditions, such as asthma or chronic respiratory diseases, exposure to air pollutants can exacerbate their condition.

[0005] Although the extent to which people of different ages or with different physical conditions are affected by air pollution depends on their individual health conditions, people of all ages are affected by poor air quality. Air pollution has a particularly greater impact on the respiratory system of infants, children, and the elderly.

[0006] Therefore, in order to avoid inhaling harmful substances in the air (such as PM2.5 suspended particles), viruses, germs, droplets from others, or pollen, many people now wear masks to protect their respiratory organs when going out or taking public transportation, thus avoiding inhaling harmful substances.

[0007] Masks are usually worn over the mouth and nose to filter the gases that are inhaled and exhaled through the nose, blocking harmful gases, unpleasant odors, and droplets from others. Most masks are made of cloth, non-woven fabric, or paper. If you use a mask made of non-woven fabric or paper, you should discard it after each use.

[0008] However, cotton masks only block wind, dust, or black smoke from exhaust pipes and provide warmth; activated carbon masks can absorb organic gases or odors, but they cannot filter airborne particles, viruses, or bacteria. Activated carbon masks are disposable and must be discarded after use; non-woven masks (also known as surgical masks) mainly rely on ultra-fine electrostatic fiber cloth and filter layers to filter out more than 90% of 5-micron particles (about the size of cells and larger bacteria), but non-woven masks are also disposable and must be discarded after use; another type of mask that can block the vast majority of viruses, germs, droplets, and airborne transmission is the N95 mask. Although N95 masks can block harmful substances, they cannot be worn for extended periods and are also disposable and must be discarded after use.

[0009] However, apart from cloth masks, all of the above-mentioned masks are disposable and need to be discarded after use, which will put a great burden on the environment and cause environmental problems when disposing of them. Reusable cloth masks, on the other hand, cannot block viruses, germs or other harmful substances.

[0010] However, currently disposable or reusable masks have two straps on both sides and a pressure strip on the top edge. When a user wears the mask, the pressure strip is flexible and malleable, allowing it to conform to the user's nose and face shape, so that the top edge of the mask can cover the user's nose and face without gaps between the mask and the user's face. Currently, the pressure strips used in masks are usually made of aluminum or other metal sheets. The pressure strip is a rigid material, and it is in direct contact with the user's face, which can easily cause pressure marks or other discomfort. Moreover, the ends of the pressure strip are relatively sharp, which can easily scratch the user's facial skin.

[0011] Therefore, how to create a mask that can improve the comfort of users while wearing it, and whose padding structure has a filtering function to filter the air entering the mask from the outside, so as to prevent polluting particles in the air from entering the mask, is a problem that those skilled in the art want to solve.

[0037] To provide a better understanding of the structural features and effects achieved by the present invention, preferred embodiments and detailed descriptions are provided below:

[0038] Traditional mask structures allow the upper edge of the mask to conform to the user's nose and face shape due to the flexibility and malleability of the pressure strip, ensuring a tight fit without gaps. However, the pressure strips currently used in masks are usually made of aluminum or other metal sheets. As rigid materials, these strips are in direct contact with the user's face, which can easily cause pressure marks or other discomfort. Furthermore, the sharp ends of the pressure strips can easily scratch the user's facial skin.

[0039] In view of the above-mentioned problems, the present invention provides a mask structure with a nose pad to improve the problems of the present invention. The present invention provides a soft pad on the inside of the mask. The elasticity of the soft pad prevents the nose strip from being fixed to the bridge of the nose for a long time due to wearing the mask for a long time, thus preventing discomfort.

[0040] The invention will be described in detail below by way of the drawings illustrating various embodiments thereof. However, the concept of the invention may be embodied in many different forms and should not be construed as being limited to the exemplary embodiments set forth herein.

[0041] First, please refer to Figure 1A, which is a schematic diagram of a mask structure with a nose pad according to an embodiment of the present invention. As shown in the figure, the mask structure with a nose pad in this embodiment includes a mask body 10 and a soft pad body 20.

[0042] Referring further to Figure 1B, which is a perspective view of a mask structure with a nose pad according to an embodiment of the present invention, in this embodiment, the mask body 10 further includes a first protective layer 12, a first filter layer 14, and a skin-friendly layer 16. The first protective layer 12, the first filter layer 14, and the skin-friendly layer 16 are arranged sequentially from the outside to the inside. A pressure strip 11 is disposed on one side of the mask body 10, and a receiving space 18 is provided in the skin-friendly layer 16. The receiving space 18 is used to buffer the user from inhaling a gas from the external environment. Specifically, the pressure strip 11 can be disposed on the upper side of the mask body 10, that is, the bridge of the nose side, or on the lower side of the mask body 10, that is, the chin side. This embodiment uses the bridge of the nose side as an example, but it is not a limitation.

[0043] Please refer to Figure 1C, which is an enlarged structural schematic diagram of the nose bridge groove of a mask structure with a nose pad according to an embodiment of the present invention, and Figure 1D, which is an enlarged structural schematic diagram of a mask structure with a nose pad according to an embodiment of the present invention. As shown in the figures, in this embodiment, the soft pad 20 is disposed on an inner side 13 of the mask body 10 and covers the pressure strip 11. The soft pad 20 includes a body 21 and a covering member 28. The body 21 has a plurality of perforations 211. The body 21 has a first side 201 and a second side 203, which are respectively the lower side and the upper side of the body 21, that is, the first side 201 and the second side. 203 is disposed opposite to the covering 28. A third side 22 and a fourth side 24 are respectively disposed on both sides of the body 21. In this embodiment, the third side 22 and the fourth side 24 are the left side and the right side of the covering 28, respectively. That is, the third side 23 and the fourth side 24 are disposed opposite to the covering 28. In this embodiment, the third side 23 and the fourth side 24 are adjacent to the first side 201 and the second side 203, respectively. Therefore, at least one edge angle formed by the third side 22 and the fourth side 24 corresponding to the first side 201 and the second side 203 is exemplified by the chamfered edge as a non-acute edge.

[0044] In this embodiment, a nose bridge groove 207 is further provided on the body 21 of the third side 22 and the fourth side 24. The covering member 28 covers the body 21, the third side 22, the fourth side 24 and the nose bridge groove 207. The body 21 is a foam or a fluffy fiber. In the illustration shown in FIG1D, the nose bridge groove 207 in the illustration of this embodiment should also be covered by the filter layer 23. However, the illustration of the nose bridge groove 207 is omitted in the illustration for the sake of clarity and readability.

[0045] In this embodiment, the soft pad 20 is disposed on the mask body 10 with its first side 201 as the lower side and connected to one side of the pressure strip 11 with one inner side 13 of the mask body 10. The other side of the soft pad 20 is not connected to the inner side 13 of the mask body 10. That is, in this embodiment, the second side 203 of the soft pad 20 is not disposed on the mask body 10 as the upper side and is disposed separately from the mask body 10. In this way, the covering 28 will not fix the shape of the body 21, and the body 21 can extend within the covering 28 so that the soft pad 20 has good fluffiness and can change its external shape at will with external force.

[0046] Please refer to Figure 2A, which is a schematic diagram of the usage state of an embodiment of the present invention, and Figure 2B, which is an enlarged schematic diagram of the usage state of an embodiment of the present invention. As shown in the figures, in this embodiment, a gas flows into (at the dashed arrow in the figure) or flows out (at the dotted arrow in the figure) through the mask body 10 and the soft pad body 20.

[0047] The advantage of this embodiment is that by providing the soft pad 20 on the inner side of the mask body 10, the elasticity of the soft pad 20 prevents the wearer's nose bridge from being fixed by the pressure strip 11 for a long time due to prolonged mask wearing, thus avoiding discomfort. The upper two sides of the soft pad 20 are respectively provided with non-acute edges, that is, the third side 22 and the fourth side 24 form non-acute edges with the second side 203, which increases the comfort of wearing and avoids the soft pad 20 causing discomfort to the user. In this embodiment, the third side 22 and the fourth side 24 are beveled, that is, the original right angle edge is modified into an obtuse angle edge to achieve the purpose of shape modification.

[0048] Here is an example of implementation:

[0049] When a user 90 wears the mask structure with nose pad of this embodiment, the soft pad 20 is located between the mask body 10 and the user 90, and fills the gap between the bridge of the user 90's nose and the mask body 10. The soft pad 20 directly contacts the user 90's nose and cheeks on both sides of the nose. Since the soft pad 20 covers the pressure strip 11, and although the pressure strip 11 is usually made of aluminum sheet or other metal sheet or plastic-coated metal strip or plastic-coated metal sheet, due to the setting of the soft pad 20 in this invention, the pressure strip 11 will not directly contact the user 90's nose and cheeks. That is, when the mask structure is worn, the second side, i.e. the upper side 203 of the soft pad 20 is folded towards the top of the pressure strip 11.

[0050] Furthermore, because the pressure strip 11 is easily bent due to the aforementioned aluminum sheet or thin metal sheet, the pressure strip 11 can be shaped according to the shape of the user's nose and cheeks, so that the soft pad 20 located outside the pressure strip of the mask body 10 fits snugly against the user's nose and cheeks.

[0051] Furthermore, the nose bridge groove 207 provided at the contact point between the soft pad 20 and the user's nose can fit the soft pad 20 to fit the user's nose extremely well without causing discomfort. Moreover, the soft pad 20 is made of soft material and has good fluffiness, which will not cause discomfort to the user when wearing the mask body 10, for example, by preventing the pressure strip 11 from pressing or rubbing against the user's nose.

[0052] In addition, in this embodiment, the soft pad 20 further includes a first surface 25 and a second surface 27 on both sides. The first surface 25 is disposed on the side of the soft pad 20 opposite to the pressure strip 11, and the second surface 27 is disposed on the inner side of the soft pad 20 opposite to the mask body 10. The curvature of the first surface 25 is equal to the curvature of the second surface 27, which is a symmetrical state (as shown in Figure 1D).

[0053] The curvature of the first surface 25 and the second surface 27 can also be asymmetrical. Please refer to Figure 3, which is a schematic diagram of another usage state of an embodiment of the present invention. As shown in the figure, the curvature of the second surface 27 of the soft pad 20 is greater than the curvature of the first surface 25. The curvature of the first surface 25 of the soft pad 20 is close to a plane. Therefore, as shown in Figure 3, the cross-sectional shape of the soft pad 20 is D-shaped. In this embodiment, the nose bridge groove 203 shown in Figure 3 is also covered by the covering member 28. However, the nose bridge groove 203 is omitted in the figure only to make the illustration clear and easy to read.

[0054] In other words, when the user 90 wears a mask with the structure of this embodiment, the second surface 27 of the soft pad 20 contacts and fits against the user's face, and the first surface 25 of the soft pad 20 is close to the inner side 13 of the mask body 10. In this way, the other side of the soft pad 20 that is not fixed to the inner side 13 of the mask body 10 is less likely to lift up, so as to avoid contact with the user 90's face and cause friction.

[0055] Next, please refer to Figure 4A, which is a schematic diagram of the structure of a soft pad according to an embodiment of the present invention. As shown in the figure, the soft pad 20 of this embodiment further includes a second filter layer 23 and a sterilization layer 26. The sterilization layer 26 is disposed between the body 21 and the second filter layer 23, that is, the second filter layer 23 and the sterilization layer 26 are disposed between the covering member 28 and the body 21. The sterilization layer 26 covers the outer layer of the body 21, and the second filter layer 23 covers the body 21 having the sterilization layer 26. Furthermore, in this embodiment, any edge corner of the third side 23 and the fourth side 24 is chamfered as an example of a non-acute edge. The third side 22 and the fourth side 24 of the soft pad 20 are further provided with a first edge corner 222 and a second edge corner 224, as well as a third edge corner 242 and a fourth edge corner 244, respectively. The second edge corner 224 and the fourth edge corner 244 are respectively provided on the lower two sides of the soft pad 20, that is, on both sides of the first side 201, and the first edge corner 222 and the third edge corner 242 are respectively provided on the upper two sides of the soft pad 20, that is, on both sides of the second side 203. The first edge corner 222, the second edge corner 224, the third edge corner 242 and the fourth edge corner 244 of this embodiment are arc-shaped edge corners, so as to further use arcs to replace right angles of the edges, thereby achieving the purpose of shape modification and avoiding discomfort when wearing them, such as avoiding sharp edges from poking or pricking the user's face on both sides of the nose.

[0056] Because the soft pad 20 has the second filter layer 23 (refer to Figures 2A and 2B), when the user 90 breathes, the second filter layer 23 can filter the gas entering the space 18 of the mask body 10 from the outside of the mask body 10 (refer to the dotted arrows in Figures 2A and 2B), so as to filter out dust, particulate matter and other pollutants in the gas, thereby preventing pollutants in the gas from entering the mask body 10 from the soft pad 20, and preventing the user from inhaling pollutants in the gas.

[0057] Conversely, it can also filter the gas containing droplets exhaled by the user 90 (refer to the dotted arrows in Figures 2A and 2B), allowing the gas exhaled by the user 90 to pass through the second filter layer 23 for filtration, preventing the droplets exhaled by the user 90 from being transmitted to the external environment.

[0058] Finally, the second filter layer 23 is covered by the covering member 28, which protects the second filter layer 23, the sterilization layer 26 and the body 21 inside the soft pad 20, and prevents the second filter layer 23, the sterilization layer 26 and the body 21 from getting dirty.

[0059] When the soft pad 20 of this embodiment is disposed on the mask body 10, when the user 90 wears the mask body 10, the soft pad 20 makes the mask body 10 fit the face of the user 90 and can improve the comfort of the user 90 wearing the mask body 10.

[0060] Furthermore, the gas located in the mask body 10 enters the mask body 10, the second filter layer 23 of the soft pad 20 filters the polluting particles in the gas, and the sterilization layer 26 eliminates the bacteria or viruses in the gas, so as to prevent the polluting particles, bacteria or viruses in the gas from entering the mask body 10 and avoid the user 90 from inhaling polluting particles or being infected with bacteria or viruses.

[0061] Further, please refer to Figure 4B, which is a structural schematic diagram of a soft pad according to an embodiment of the present invention, and Figure 4C, which is a structural schematic diagram of a soft pad according to an embodiment of the present invention. As shown in the figures, the sterilization layer 26 in this embodiment can be replaced with an electrostatic layer 29 (as shown in Figure 4B), or the electrostatic layer 29 can be added between the sterilization layer 26 and the body 21 (as shown in Figure 4C). The electrostatic layer 29 can adsorb bacteria or viruses that have not been eliminated by the sterilization layer 26. That is, in this embodiment, as shown in Figure 4B, the second filter layer 23 and the electrostatic layer 29 are disposed between the covering member 28 and the body 21, or, as shown in Figure 4C, the second filter layer 23, the sterilization layer 26 and the electrostatic layer 29 are disposed between the covering member 28 and the body 21.

[0062] The embodiments shown in Figures 4A to 4C above are in which the third side 22 and the fourth side 24 are sealed together by ultrasonic pressing or hot pressing, so that the combination of the second filter layer 23, the sterilization layer 26 and the electrostatic layer 29 covers the body 21. In addition, as shown in the embodiments in Figures 4D to 4F, the body 21 can extend to the openings of the third side 22 and the fourth side 24, that is, the schematic diagram shown in the side view of Figure 1A. Although the body 21 is covered by the combination of the second filter layer 23, the sterilization layer 26 and the electrostatic layer 29, the body 21 can still be seen from the side.

[0063] Referring further to Figures 5 to 7, which are enlarged schematic diagrams of other embodiments of the soft pad 20 of the present invention disposed on the mask body 10. As shown in Figure 5, the difference from Figure 1D is that in Figure 1D, the first side 201 of the bottom of the soft pad 20 is connected to the mask body 10, while in Figure 5, a second side 202 of the upper part of the soft pad 20 is connected to the skin-friendly layer 16 of the mask body 10. As shown in Figure 6, the difference from Figure 5 is that in Figure 5, the upper part of the soft pad 20 is connected to the skin-friendly layer 16 of the mask body 10, while in Figure 6, the middle part of the soft pad 20 is connected to the mask body 10, particularly the middle part of the first surface 25 is connected to the skin-friendly layer 16 of the mask body 10. Furthermore, as shown in Figure 7, in the previous embodiment, the arc surface where the first surface 25 of the soft pad 20 is located is flat against the mask body 10, therefore, the soft pad 20 is not disposed on the skin-friendly layer 16 of the mask body 10 with the first surface 25.

[0064] The above embodiment shows that the first filter layer 14 is a general filter structure. The following describes the first filter layer 14 as further including a pleated layer, that is, the first filter layer 14 itself contains a pleated structure, thus having better filtration area and air permeability.

[0065] Please refer to Figures 8A and 8B, which are perspective views of a mask structure with a nose pad and enlarged structural views of the nose bridge groove according to another embodiment of the present invention. As shown in the figures, the difference between Figure 8A and Figure 8A is that the first filter layer 14 in Figure 8A further includes a pleated layer 15, which includes at least one pleated piece 141. The at least one pleated piece 141 has a plurality of pleats 1513, and each of the pleats 1513 has a plurality of shaping portions 157 for fixing the pleats 1513 to the pleated layer 15. Furthermore, in this embodiment, the third side 22 and the fourth side 24 extend to both sides of the soft pad 20, and in this embodiment, all the edge angles formed by the third side 23 and the fourth side 24 relative to the first side 201 and the second side 203 are examples of non-acute edges with chamfered angles, thus making the two sides of the soft pad 20 have the shape of two arc-shaped edges. However, in this invention, all the edge angles formed by the third side 23 and the fourth side 24 relative to the upper side 203 can be set as non-acute edges.

[0066] Please refer to Figure 8C, which is a schematic diagram of the structure of the wrinkled layer of the present invention. As shown in the figure, the wrinkled layer 15 of this embodiment includes a first wrinkled sheet 152 and a second wrinkled sheet 154. Both the first wrinkled sheet 152 and the second wrinkled sheet 154 have wrinkles 1513. The first wrinkled sheet 152 has a first joining edge 1521, and the second wrinkled sheet 154 has a second joining edge 1541. The first joining edge 1521 of the first wrinkled sheet 152 and the second joining edge 1541 of the second wrinkled sheet 154 are joined together.

[0067] The first joint edge 1521 and the second joint edge 1541 connect the pleats 1513 to fix the pleats 1513, thereby preventing the pleats 1513 from deforming after the first pleat piece 152 and the second pleat piece 154 are stretched open.

[0068] In this embodiment, the first joining edge 1521 and the second joining edge 1541 are arc-shaped, but they can also be other shapes, such as straight lines, which will not be described in detail here.

[0069] Furthermore, in this embodiment, please refer to FIG8D, which is a schematic diagram of the structure of the wrinkled layer of another embodiment of the present invention. As shown in the figure, the wrinkled layer 15 of this embodiment differs from the wrinkled layer 15 of the above embodiment in that the wrinkled layer 14 of this embodiment includes a plurality of wrinkled pieces 155 (two or more pieces). Each wrinkled piece 155 has wrinkles 1513 and at least one joining edge 1511. The at least one joining edge 1511 of each wrinkled piece 155 is joined with the at least one joining edge 1511 of the adjacent wrinkled piece 155. The wrinkled pieces 155 after being stretched out can be pressed to form the wrinkled layer 15 with a three-dimensional geometric shape, such as forming a cup-shaped wrinkled layer. Furthermore, please refer to FIG8E, which is a schematic diagram of the structure of the wrinkled layer according to another embodiment of the present invention. The difference between FIG8D and FIG8E is that FIG8D shows an example of two wrinkled pieces 155 joined through the joint edge 1511, while FIG8E shows four wrinkled pieces 155 joined through the joint edge 1511.

[0070] In addition, in this embodiment, please refer to FIG8F, which is a schematic diagram of the structure of the wrinkled layer of another embodiment of the present invention. As shown in the figure, the wrinkled layer 15 of this embodiment includes a wrinkled piece 15A and a fixing piece 15B. The wrinkled piece 15A is disposed on the fixing piece 15B. There are multiple shaping portions 157 between the wrinkles 1513 in the periphery of the wrinkled piece 15A. The shaping portions 157 connect the fixing piece 15B and the wrinkled piece 15A. The fixing piece 15B can also be disposed on the inner side of the protective layer 12, or the protective layer 12 can be directly used as the fixing piece 15B. Therefore, the wrinkled piece 15A can be directly disposed on the inner side of the first protective layer 12 and fixed to the first protective layer 12 by the shaping portions 157.

[0071] The embodiments described above are examples of a mask structure with a nose pad. By providing a soft pad on the inside of the mask, the elasticity of the soft pad prevents discomfort caused by the nose strip being fixed to the bridge of the nose for a long time due to prolonged mask wearing. Furthermore, the curved shape on both sides of the soft pad increases user comfort and prevents discomfort caused by pressure marks from the nose strip.

[0072] The order of the steps in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent variations and modifications made in accordance with the shape, structure, features and spirit described in the claims of the present invention should be included within the scope of the claims of the present invention.
