no. 1 Embodiment approach

[0032] figure 1 It is a perspective view schematically showing the shape and arrangement of each layer of the mask body constituting the multi-layer mask of the first embodiment of the present invention. And, the 2nd figure is a front view schematically showing the appearance of the multilayer mask of the first embodiment, and the 3rd figure is a cross-sectional view along the arrow III-III direction in the 2nd figure that schematically shows the laminated structure of the mask body. In addition, in Fig. 1 and Fig. 3 , in order to explain the structure of the mask main body in an easy-to-understand manner, each layer is shown with a thickness thicker than the actual one.

[0033] The multi-layer mask 1 of the present embodiment comprises a mask body 2 for covering the mouth and nose of the wearer, and a rope body 3 installed on the left and right ends of the mask body 2, and the rope body 3 is locked on the wearer's ear. Ministry, head, thus wear with the mode that mask body ...

Abstract

A multilayered mask that while securing satisfactory breathability for wearers, prevents the penetration of bacteria and viruses into the wearers' bronchi and exhibits excellent antibacterial / antiviral properties. The multilayered mask comprises a rectangular mask main body to be worn so as to cover the nose and mouth parts of a wearer, the mask main body having a thin four-layered structure consisting of a laminate of outermost layer of spun bonded nonwoven fabric capable of adsorbing atmospheric flotage, etc., first intermediate layer of electrostatically charged melt blown nonwoven fabric,second intermediate layer of melt blown nonwoven fabric containing an inorganic antibacterial agent consisting of silver ion and zeolite and innermost layer of spun bonded nonwoven fabric capable of moisture retention for prevention of drying of the nose and mouth parts.

Description

technical field [0001] The present invention relates to a multi-layer mask which is effective in preventing infection of bacteria, viruses, etc., countermeasures against hay fever, preventing inhalation of airborne debris, and the like. Background technique [0002] In the past, in order to prevent dust, pollen, bacteria, viruses, etc. in the air from invading the bronchi of the human body through breathing, it is widely known to wear a mask. Made of elastic cords for the ears, and worn to cover the nose and mouth. This kind of mask is used to keep the throat and nose warm, to prevent the inhalation of house dust and dust that are visible to the naked eye, or to prevent the wearer from coughing and sneezing secretions such as saliva from forming droplets, etc. , played a certain role. However, with the expansion of new influenza viruses (eg, highly virulent avian influenza virus (H5N1 type), severe acute respiratory syndrome (SARS) virus, etc.) infection in recent years, m...
