Description

Nano film mask

A medical grade film mask, especially an extremely thin mask using PTFE as the main filter material.

Medical grade masks are mainly designed to protect the human respiratory system from external pathogens and to isolate biological particles. Therefore, medical grade masks belong to the National Institute for Occupational Safety and Health (NIOSH). N, R, P, N, the filter material for non-oily particles.

The mask, commonly referred to as the N95, means that more than 95% of non-oily particles can be filtered, which is a common grade for medical grade masks.

The material of the commercially available N95 mask is composed of polypropylene (PP), polyethylene terephthalate (PET) or a combination thereof, and the effect of filtering 95% or more of non-oily particles is N95. Masks are commonly used in PP, PET or combinations thereof with a total stacking number of 5 to 8 layers, such that the mask thickness is greater than 2 millimeters (mm).

Moreover, the mask using PP or PET as the main filter structure of the non-surface layer relies on the effect of electrostatic adsorption, so that the thicker the filter layer is, the better the filtration effect is. Therefore, the commercially available N95 masks often have problems such as sultry heat, heavy weight, and poor adhesion to the face compared to general masks.

In order to support the heavy structure of the N95 mask, and in order to be able to tie the mask when wearing, it conforms to the shape of the face. Therefore, compared to general masks, hook materials for N95 masks are usually It is thicker to provide sufficient tensile strength. However, similar designs can cause the user to feel that the head or ear is tightened by the mask when wearing the N95 mask. If worn for a long time, it may cause uncomfortable feelings such as pain or pressure in the wearing part.

In addition, due to the heavy structure of the commercially available N95 mask, the mask and the nose are not easy to fit, and it is necessary to use an additional metal or other hard material to be placed on the upper edge of the mask for attaching and fitting the N95 mask to the nose. At the office. However, this method of pressing and fitting often makes the user feel uncomfortable when wearing it, and the pressing piece of the stiff material is not easily adjusted with the shape of the nose, and there is often a problem of poor adhesion.

Based on the various defects of the commercially available N95 mask, this creation aims to propose a very thin film mask, using a new generation of film layers as the main filter structure, reducing the thickness and weight of more than half of the masks, and thus solving the sultry heat and tightness. Good and the wearing place have problems such as oppression.

A film mask of the present invention comprises: a body formed by overlapping an outer skin layer, a first protective layer, a second protective layer, a film layer and an inner skin layer. Wherein the film layer is located between the first protective layer and the second protective layer, the first protective layer and the second protective layer are located between the outer skin layer and the inner skin layer; and at least one suspension member is connected to the two side edges of the body.

In the foregoing mask body, the structure is only formed by overlapping the outer layer, the first protective layer and the second protective layer, the film layer and the inner surface layer, and the thickness thereof is not more than 1 mm, which is much smaller than the commercially available N95 mask. Moreover, this creation utilizes the porous material properties of the film layer to filter particles and contaminants, and is not a general electrostatic adsorption method, and can achieve a light and soft effect while maintaining a high filtration effect.

For this reason, the film mask of this creation can be combined with the structural improvement proposed by the components such as the pressing piece or the hanging piece, and the user can be more comfortable and uncompressed without using the pressing piece or the hook of the stiff material. Wearing method.

In order to understand the technical features and practical effects of the present invention, and in accordance with the contents of the specification, the present invention will be further described in detail with reference to the preferred embodiment shown in the following: a nano film mask of the present invention, please Referring to FIG. 1 , it is a schematic diagram of the main body of the present invention. The body 10 is formed by overlapping an outer skin layer 12 , a first protective layer 14 , a second protective layer 15 , a film layer 16 and an inner skin layer 13 . The thin film layer 16 is located between the first protective layer 14 and the second protective layer 15 , and the first protective layer 14 and the second protective layer 15 are located between the outer surface layer 12 and the inner surface layer 13 .

In the body 10, the material of the film layer 16 may be polytetrafluoroethylene (PTFE), and the material of the outer layer 12 may be a multi-layer polypropylene (PP) having a moisture-proof and breathable effect, and the first protective layer 14 and the first layer The material of the second protective layer 15 may be an extremely light and thin polyethylene terephthalate (PET) supporting the film layer 16, and the inner surface layer 13 may be made of a skin-friendly composite fiber. The skin-friendly composite fiber may be a super-soft composite fiber non-woven fabric, a wool composite fiber or a soybean protein composite fiber.

Since the film layer 16 is made of a material having a filtration percentage of 99 or more and 0.3 micrometer (μm), the main structure is polytetrafluoroethylene. Therefore, the PP selected for the outer layer 12, the PET selected for the first protective layer 14 and the second protective layer 15, or the skin-friendly composite fiber material of the inner skin layer 13 are superposed on each other to form the body 10.

Please refer to FIG. 2, which is another schematic diagram of the main body. When the weather is cold, the user may need a mask to contain the function of protecting the cold. Therefore, a heat insulating layer 18 may be disposed between the outer skin layer 12 and the first protective layer 14, and the heat insulating layer 18 may be a polyester material such as PP or PET.

Please refer to FIG. 3 , which is a front view of the first embodiment of the present invention. The film mask comprises a body 10 , and the body 10 can be further divided into a side edge 20 , an upper edge 30 and a lower edge 40 , and defines a side edge 20 . The side portion that is in contact with the cheek when worn by the user, the upper edge 30 is the upper side portion that contacts the user's nose or nose, and the lower edge 40 is the lower side portion that contacts the user's lower jaw.

The side edges 20 of the left and right sides of the body 10 may have a plurality of perforations 22 connected to a suspension member 60, respectively. In the present embodiment, a suspension member 60 is used to attach to the head or neck of the user, and a pressing piece 50 may be provided at the position of the upper edge 30. The pressing piece 50 may be a hard metal material or a soft and elastic plastic material.
