Description

BACKGROUND OF THE INVENTION

Field of the invention

The present invention relates to face masks, and more particularly to a face mask with embedded nasal pad.

Description of the Prior Art

Today's world is exposed to rapid industrialization and urbanization, which ultimately results in the construction and operation of many factories, coal-fired power plants, automobiles and motorcycles, all of which produce exhaust fumes, leading to increased air pollution, which reduces air quality. For example, airborne PM2.5 penetrates deep into the human respiratory tract and causes various diseases such as bronchitis, asthma and cardiovascular diseases to the detriment of human health. In 2013, the World Health Organization (WHO) classified air pollution as the leading environmental cause of cancer. In Taiwan, seven of the ten most common cancers are attributed to air pollution. In addition, public health is constantly subject to further risks as a result of diseases caused by bacteria and viruses, such as the SARS epidemic, bird flu and swine flu (H1N1). In the face of these health risks, people attach more importance to the use of face masks.

Currently, the estimated face mask used worldwide is approximately 10 Billions, and about 80% of them are flat, non-woven face masks. Although commercially available flat face masks and even some N95 respirators are portable and inexpensive, they have poor airtightness. According to the Taiwanese standards CNS14774 and 14755 , the the D2 Concerning air tightness detection procedures for respiratory protective equipment (N95 / FFP2), a good respirator, when worn by the user, must be airtight 100 reach (100% = 100 airtightness = 1% leak rate). One on 100 People's test conducted by the Taiwanese Institute for Work, Safety and Health at Work showed that two commercially available N95 masks achieved airtightness of 13.9 and 21.8, respectively. The test also showed that conventional face masks achieved an average airtightness of 3.1 and thus an average leak rate of 33%, which means that conventional face masks can not effectively prevent the entry of PM2.5. To achieve a degree of airtightness, any conventional face mask is provided with a plastic nose piece on its top. The plastic nose piece is provided in the form of a plastic strip or in the form of an iron or aluminum wire which is enclosed by a plastic wrapper to improve airtightness by closing the gap between the user nose and the cheeks. However, the nasal area of the face mask often tends to leak due to the shape and size of the nose and the height of the nose bridge, making it difficult to prevent leakage. Only minutes after a user has adapted the nasal piece of the face mask to the shape of his nose by pressing on the upper side of the face mask, there is a significant gap between the user's nose and his cheeks as a result of even minor facial muscle movements. Further, the lateral sides of the face mask tend to allow airborne contaminants, bacteria and viruses to pass through, as the lateral sides of the face mask are attached to the user's ears by means of bands or elastic strips. These disadvantages of conventional face masks have not been solved.

Without wearing a face mask that can filter out airborne contaminants, people are more prone to develop cancer and other chronic conditions, such as high blood pressure and diabetes, or even die of complications. In addition, people in hospitals and public spaces who do not wear the face mask are more likely to be susceptible to cross-infection and thus higher disease rates. Moreover, the conventional face mask, when worn by a user, is attached to the user's mouth and nose, that is, at both locations of the air exchange, with the result that the breathing resistance increases, whereupon more air passes through the gap the nose and cheeks are pulled; this is the main reason why the leak rate is usually around 40%. The greater the leak rate, the more likely the user will be exposed to the health risks listed above. These are the reasons why the disadvantages of conventional non-woven face masks have existed for decades and are still unresolved

In addition, warm exhalation air of the user wearing a face mask rises and flows through the gap between the bridge of the nose and the top of the face mask, fogging the visor and impairing the user's eyesight, thus increasing the safety of the user when walking or driving impaired. In addition, even a commercially available upholstery foam for the nose in a face mask does not make the airtightness in the nasal area the face mask can be satisfactorily improved or maintained because the face mask can not be adapted to the contours of the user's nose and cheekbones; This is because the nasal foam is rather thick and is located between the face mask and the bridge of the nose, so there is the possibility of creating gaps between the face mask and the foam and between the face mask and the cheeks.

The US 2012/0 199 142 A1 discloses a mask having a main body and two cords which, when pulled over the ears, are intended to fix the mask body at a particular location on the user's face. On the mask body folded areas are provided, which make contact with the skin of the user.

The US 2015/0 056 102 A1 further discloses a deodorizing mask having an air-permeable main body to be placed over the nose and mouth. The main body comprises two nonwoven fabrics, a deodorant chemical deodorant layer and a dustproof layer.

The US Pat. No. 3,664,335 A discloses a disposable face mask for surgeons that includes a flexible pad that covers the nose and mouth of the user. The pad consists of two outer non-woven fabric layers surrounding an inner layer of a filter material.

The US 5 553 608 A discloses a face mask with a filter body with which liquids, particles and aerosols from the ambient air can be filtered out. The filter body consists of several layers of a filter material of substantially rectangular shape, which are folded together.
