Description

Disposable mask

The present invention relates to a mask, in particular to a mask that can be disposable and discarded by users.

In daily life or in the medical system, disposable and disposable masks have been widely and widely used. Recently, with the rapid spread of the COVID-19 virus in various countries, masks have become a daily necessity for people all over the world. , and even become a strategic material for various countries, resulting in its usage not growing exponentially, but almost exponentially.

As shown in Figure 1, generally speaking, the common disposable masks 1 on the market generally have a three-layer structure, which are the first non-woven fabric layer 11, the second melt-blown non-woven fabric layer 12, And the third non-woven fabric layer 13 that contacts the outside world. Usually, the third non-woven fabric layer 13 located in the outermost layer is waterproof, which can block the adhesion of droplets or blood with viruses; the second layer of melt-blown non-woven fabric layer 12 located in the middle layer In order to block and filter viruses, bacteria or fine dust; and the innermost first non-woven layer 11 must be in contact with the face, so it is usually a composite material non-woven to emphasize the comfort of the skin!

However, for a long time, because the traditional disposable masks are mainly composed of three layers of non-woven fabrics, although this structure can effectively block or filter viruses and bacteria, but because most of the non-woven fabrics are made of polypropylene or polyethylene and other materials , especially when the first non-woven fabric layer 11 on the side close to the user's mouth and nose is also made of non-woven fabric, there will be problems such as airtightness and difficulty in absorbing the moisture exhaled by the user. The most common is that when the user wears glasses or goggles, the heat generated by breathing will condense on the lenses of the glasses or goggles shortly after the user wears the mask, and the lenses of the glasses or goggles will be fogged. Wearing a mask can cause fogging of the eyes. For ordinary users, it may cause poor vision in mild cases, and may cause danger in severe cases. For example, if the user is a doctor who wears glasses or goggles, when the doctor is performing surgery Fog on the lenses of glasses or goggles will cause inconvenience and danger to surgery; or when users who wear glasses or goggles are driving, immediate short-term visual impairment is likely to be dangerous. Therefore, how to provide a disposable mask that can easily absorb the heat or moisture generated by the user's breathing, is not easy to cause fog on the lens, and increases the user's comfort is an important issue!

In addition, with the severe epidemic, the consumption of disposable masks has also increased rapidly. According to a report in the "Environmental Science and Technology journal" magazine, the number of disposable masks used globally is as high as 1,940 per month. 100 million, which also means that nearly 200 billion disposable masks will be discarded every month in the world! As mentioned above, since most of the non-woven materials used in disposable masks are made of polypropylene or polyethylene and other materials, such plastics The material not only cannot be decomposed naturally, but even causes great harm 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 the disposable masks are treated as garbage, it is good Disposal, because it is not easy to decompose, the impact on the environment is also a big concern! Therefore, how to provide a more environmentally friendly disposable mask is also another important issue!

To sum up, how to provide a disposable mask with good water absorption in the inner layer of the mask and environmental protection function is one of the major issues of today's disposable masks.

In view of the above-mentioned problems, the object of the present invention is to provide a kind of disposable mask, which is to replace part of the non-woven cloth by paper material, to reduce the usage of non-woven cloth, and then reduce the environmental impact of the disposable mask, and simultaneously use the paper material as a discarded cloth. The inner layer of the mask can increase the effect of absorbing moisture and avoid fog on the glasses.

In order to achieve the above object, the present invention discloses a disposable mask, which can 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 paper fiber material, and has a contact surface contacting the user's mouth and nose and a joint surface opposite to the contact surface, and the quality of the paper fiber material accounts for the paper protective layer. more than 90% of the mass; the filter layer is mainly composed of melt-blown non-woven material, and one surface of the filter layer is overlapped with the joint surface of the paper protective layer; and the barrier layer is mainly composed of non-woven material, the barrier layer One side is overlapped with the other side of the filter layer.

In one embodiment, the preferred thickness of the paper protective layer is 0.06mm˜0.26mm.

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.

In one embodiment, a plurality of micro-protrusions are formed on the joint surface of the paper protection layer.

In one embodiment, the disposable mask system may further include an isolation film, the isolation film is mainly composed of non-woven material, and is stacked between the paper protective layer and the filter layer.

In one embodiment, the release film is formed on the bonding surface of the paper protection layer.

In one embodiment, the preferred thickness of the isolation film is 0.005mm˜0.01mm.

In one embodiment, the disposable mask can further include a printing layer, which is made of paper fiber material, which is overlapped with the other side of the barrier layer, wherein the quality of the paper fiber material of the printing layer is It accounts for more than 90% of the quality of the printing layer.

In one embodiment, the other side of the blocking layer is partially overlapped with the printing layer.

In one embodiment, the barrier layer or the non-woven material of the barrier film comprises polypropylene or polyethylene.

In one embodiment, the meltblown non-woven fabric material of the filter layer comprises polypropylene or polyethylene; or comprises polyester or polyurethane.

To sum up, the present invention discloses a disposable mask, which uses a paper protective layer with better water absorption as the inner layer of the disposable mask, so it can reduce the overall usage of non-woven fabrics that are not easily decomposed for the disposable mask; in addition, Since the disposable mask of the present invention uses a paper protective layer with better water absorption as the inner layer of the disposable mask, the disposable mask of the present invention can effectively and quickly absorb the moisture exhaled by the user, in addition to taking into account the user In addition to the comfort, it can effectively prevent water vapor from forming mist on the user's glasses, so it can avoid the temporary poor vision caused by the fog, thereby avoiding the inconvenience or danger caused by the temporary poor vision.
