Description

Technical Field

[0001] The invention relates to a mask, in particular to a mask which can be used once and then discarded by a user. Background Art

[0002] In daily life or in the medical system, disposable masks have been commonly and widely used. Recently, as the COVID-19 virus has spread rapidly in various countries, masks have become a necessity for people in all countries of the world, and even a strategic material for various countries, resulting in their usage not growing by multiples, but almost exponentially.

[0003] like Figure 1 As shown, generally speaking, the common disposable masks 1 on the market generally have a three-layer structure, namely the first non-woven layer 11 close to the mouth and nose of the person, the second melt-blown non-woven layer 12, and the third non-woven layer 13 in contact with the outside. Usually, the third non-woven layer 13 located at the outermost layer is waterproof, which can block the droplets or blood with viruses from attaching; the second melt-blown non-woven layer 12 located in the middle layer mainly uses the principle of electrostatics to block and filter viruses, bacteria or fine dust; and the first non-woven layer 11 of the innermost layer must contact the face of the person, so it is usually a composite material non-woven fabric to emphasize skin comfort!

[0004] However, for a long time, because the traditional disposable mask is mainly composed of three layers of non-woven fabric, although this structure can effectively block or filter viruses and bacteria, it is because the non-woven fabric is mostly made of materials such as polypropylene or polyethylene, especially when the first non-woven fabric layer 11 near the user's mouth and nose is also made of non-woven fabric, it will be airtight and difficult to absorb the water vapor exhaled by the user. The most common is when the user wears glasses or goggles, the hot air generated by the breath often condenses on the glasses or goggles lenses after the user wears the mask for a short time, causing the glasses or goggles lenses to fog up. For ordinary users, wearing a mask causes the eyes to fog up, which can cause poor vision in mild cases and may cause danger in severe cases. For example, if the user is a doctor wearing glasses or goggles, when the doctor is operating, the glasses or goggles lenses will fog up, which will cause inconvenience and danger in the operation; or when the user wearing glasses or goggles is driving, the real-time short-term poor vision is very likely to cause danger. Therefore, how to provide a disposable mask that can easily absorb the heat or water vapor generated by the user's breathing, is not easy to cause fogging on the lens, and increases the user's comfort is an important issue!

[0005] In addition, as the epidemic situation becomes more serious, the use of disposable masks has also increased rapidly. According to a report from the Environmental Science and Technology journal, the number of disposable masks used worldwide is as high as 194 billion per month, which means that nearly 200 billion disposable masks will be discarded worldwide per month! As mentioned above, since the non-woven materials used in disposable masks are mostly made of polypropylene or polyethylene, this type of plastic material is not only unable to decompose naturally, but also extremely harmful to animals! For example, when a large number of discarded disposable masks are discarded in the ocean, it will cause great harm to marine life! Even if disposable masks are properly treated as garbage, they are not easy to decompose, and the impact on the environment is also a major concern! Therefore, how to provide a more environmentally friendly disposable mask is also another important issue!

[0006] In summary, how to provide a disposable mask with good water absorption of the inner layer of the mask and environmental protection function is a major issue of disposable masks today. Summary of the invention

[0007] In view of the above problems, an object of the present invention is to provide a disposable mask, which replaces part of the non-woven fabric with paper material to reduce the use of non-woven fabric, thereby reducing the impact of the disposable mask on the environment. At the same time, the paper material is used as the inner layer of the disposable mask to increase the water vapor absorption effect, thereby avoiding the formation of fog on the glasses.

[0008] To achieve the above-mentioned purpose, the present invention discloses a disposable mask that can be used to cover the mouth and nose of a user, and includes a paper protective layer, a filter layer, and a barrier layer. The paper protective layer is mainly composed of a paper fiber material, and has a contact surface that contacts the user's mouth and nose and a bonding surface that is opposite to the contact surface, and the mass of the paper fiber material accounts for more than 90% of the mass of the paper protective layer; the filter layer is mainly composed of a melt-blown non-woven fabric material, and one side of the filter layer is overlapped with the bonding surface of the paper protective layer; and the barrier layer is mainly composed of a non-woven fabric material, and one side of the barrier layer is overlapped with the other side of the filter layer.

[0009] In one embodiment, the preferred thickness of the paper protective layer is 0.06 mm to 0.26 mm.

[0010] In one embodiment, the paper protective layer further comprises a resin material, and the mass of the resin material accounts for less than 2% of the paper protective layer.

[0011] In one embodiment, a plurality of micro protrusions are formed on the bonding surface of the paper protective layer.

[0012] In one embodiment, the disposable mask may further include an isolation membrane, which is mainly composed of a non-woven material and is stacked between the paper protective layer and the filter layer.

[0013] In one embodiment, the isolation film is formed on the bonding surface of the paper protective layer.

[0014] In one embodiment, the preferred thickness of the isolation film is 0.005 mm to 0.01 mm.

[0015] In one embodiment, the disposable mask may further include a printing layer, which is made of paper fiber material and overlaps with the other side of the barrier layer, wherein the mass of the paper fiber material of the printing layer accounts for more than 90% of the mass of the printing layer.

[0016] In one embodiment, the other side of the barrier layer partially overlaps with the printing layer.

[0017] In one embodiment, the non-woven material of the barrier layer or the barrier film includes polypropylene or polyethylene.

[0018] In one embodiment, the meltblown nonwoven fabric material of the filter layer includes polypropylene or polyethylene; or includes polyester or polyurethane.

[0019] In summary, the present invention discloses a disposable mask, which uses a paper protective layer with good water absorption as the inner layer of the disposable mask, thereby reducing the overall usage of non-woven fabrics that are not easily decomposed in the disposable mask; in addition, since the disposable mask of the present invention uses a paper protective layer with good water absorption as the inner layer of the disposable mask, the disposable mask of the present invention can effectively and quickly absorb the water vapor exhaled by the user, not only taking into account the comfort of the user, but also effectively preventing the water vapor from forming fog on the user's glasses, thereby avoiding temporary poor vision caused by fog, thereby avoiding the inconvenience or danger caused by temporary poor vision.
