Definitions

  • the invention relates to a method for producing a protective mask, in particular an oral and nose protective mask, and such a protective mask.
  • Protective masks in particular mouth and nose protective masks, are half-face masks which as a rule cover at least the mouth and nose. They are made from one or more paper or fleece layers and are usually fixed by means of straps, for example rubber bands, on the back of the head or behind the ears of a wearer or a person.
  • a deformable metal bracket can be provided on an upper edge, with which the protective mask can be adapted to the bridge of the nose, in order to keep the field of vision free and restrict the upward escape of breathing air.
  • the mucous membranes of the mouth and nose are potential entry points for pathogens, so a protective mask that covers the mouth and nose protects the wearer from foreign microorganisms and pathogens. Conversely, the protective mask protects other persons from droplet infection from droplets given off by the wearer when speaking and coughing.
  • DE 298 06473 U1 shows a face mask which is made of two separate parts from a material layer of a flat material.
  • the two parts are identical to one another and each have a base section and a side section which is integrally connected to the base section.
  • the base sections of the parts are connected to one another along a front edge.
  • the base section is used to cover the mouth and nose.
  • the side sections with loops extend to the rear so that the protective mask can be fastened behind the ears.
  • EP 1 575 388 B1 discloses a face mask which is punched out from a strip of material.
  • the face mask has a main part that covers the nose and mouth and two extension parts that run to the left and right of the main part, are guided along the head side and have openings with which the face mask can be held behind the ears.
  • a similar face mask is disclosed in US 4084 585 A1.
  • US Pat. No. 6,615,838 B1 shows a protective mask which is made in one piece from an elastic material.
