Definitions

  • the invention relates to a respirator mask, in particular for single use, for covering the mouth and nose of the user, based on a nonwoven material with a mask base body which is rectangular in plan view and which is formed from a rectangular flat material section of the nonwoven material, the mask base body having an upper and an upper one has lower transverse edge extending in a transverse direction and two lateral longitudinal edges extending in a longitudinal direction, which have the rectangular shape of the mask base body limit, the upper and the lower transverse edge being formed by an upper and lower fold line extending in the transverse direction, around which an upper and a lower edge section of the rectangular flat material section is folded inwards, i.e.
  • the mask base body having at least one transverse fold on itself in the longitudinal direction between the folded upper and lower edge section along two further fold lines running in the transverse direction, which are in the area when the respiratory mask is put on the user of the chin, mouth or nose of the user is at least partially foldable so that the respirator can adapt to a face surface of the user, wherein the respirator further has an upper elasticizing means, which only with its ends in the upper corner area Chen of the mask base body is attached to the mask base body, and the respiratory protection mask further has a lower elasticizing means, which is only attached to the mask base body with its ends in the lower corner areas of the mask main body, the upper and lower elasticizing means being provided when the respiratory protective mask is put on to run in a head circumferential direction of the user, preferably above or below the user's ears.
  • the invention also relates to a method for producing the respiratory protection mask.
  • EP 1 743 535 B9 shows a mask concept deviating from a rectangular mask body with transverse folds, with a protective strip at the edge is provided which receives and covers an elastic fastening element.
  • EP 1 118 278 B1 also shows a different, more complex structure of the so-called "duck bill type". In the area of the transverse edges, separately attached reinforcement strips are provided which, by the manufacturer, accommodate the elasticizing means that can be placed around the head.
  • DE 11 2014 001 988 T5 shows a rectangular respiratory mask with laterally attached and laterally protruding straps, which are each guided around the ears when the respiratory mask is put on. A similar concept is being pursued US 2016/0029716 A1 .
  • the present invention is based on the object of improving a respiratory protection mask of the type mentioned at the outset with a view to achieving further advantages in use, the aim being that it can also be manufactured economically.
  • the upper and lower elasticizing means are formed by an upper and a lower elastic thread, that the upper and the lower elastic thread are provided by the manufacturer over their respective entire extent within the upper or lower elastic thread.

  • the lower Envelope folding is arranged so that this pretensioning is not able to bulge the respiratory protection mask, which is presented by the manufacturer in the flat and flatly spread-out state, out of the flat state.
  • the upper and lower elastic threads are designed, dimensioned and arranged and fixed on the mask base body in such a way that they extend and are arranged in a straight line in the transverse direction of the respiratory mask by the manufacturer. If the respirator is then presented, for example, in a stacked arrangement of several respirators, there is no risk of the elastic threads catching or tangling with elastic threads or components of an adjacent respiratory mask, or of catching or entangling elastic threads of one and the same product with one another when removing a respiratory mask from an outer packaging .
  • the product also conveys a more pleasant and tidier visual appearance.
  • the upper and lower edge sections are available for enlarging the active mask area. This is supported by the fact that the elastic threads are fixed with their ends in the respective corner area and remain fixed. When the elastic threads are taken out of the fold and lengthened so that they can be wrapped around the head of the user, they thereby support the opening and unfolding of the upper and lower folds so that the upper and the lower fold Open the edge section and bring about an enlargement of the active mask area and then lie against the skin surface of the user in the area of the nose or chin.
  • the respiratory protection mask remains in its flat and flat-out state as provided by the manufacturer.
  • the inherent rigidity of the fleece material can have a supporting effect here; In this regard, however, the upper and lower folds and the at least one transverse fold formed between them have an even more significant effect.

  • the first and / or the second elastic thread has an elongation at break of at least 800%, in particular of at least 850%, in particular of at least 900% and in particular of at most 1100%, in particular of at most 1000%. If, for example, an elongation at break of 800% is mentioned, this means that a break only occurs when the elongation is eight times the length. The total length is then nine times the original length, since an elongation of 800% means an extension of eight times the original length.
  • the tensile strength and elongation at break are determined on elastic threads conditioned for at least 2 hours at 20 ⁇ 2 ° C. in a tensile testing machine with a tensile device at a test speed of 500 mm / min.
