The subject of the present invention is a one-off from the point of view of the highest level of hygiene Use certain face masks that are made of lengthways folded several times and at the ends non-woven fiber fleece strips provided with fastening tapes. Such face masks have already been used for a wide variety of purposes, and the embodiments, in particular, are based on this the ways of folding and the arrangement of fastening and carrying straps. Such a Hygienic mouthguards are used in medicine, for example, by the surgeon and operating personnel; But it is also used in the care of the sick and small children to protect against infection and reinfection, especially against the dreaded droplet infection, and for general health protection. It also serves to oppose the wearer protection against smoke, smog or strong smelling gases. So many arise Possible uses for a hygienic ao protection, if it differs through the selection of the material in particular can be produced cheaply and economically.

With regard to the execution and folding method, various proposals have already become known, by using, among other things, a longitudinal fold. There were masks like that too known, which, punched and shaped, resiliently yielding, only when pulled over the chin and The nose of the user was given a usable shape. One has with such mask training, which are expensive, deliberately leaving aside the need to create a particular fold; it really came down to it indicates that there was a certain amount of longitudinal and transverse stretching to match the contours of the face better adapt.

There are also such masks known, which were formed from several layers of paper. Even these were folded in a similar manner after doubling, trying, preferably To achieve strength and flexibility in the mask by arranging several layers. Such masks are uncomfortable due to the breathing resistance. There are also numerous proposals which were brought to the straps partly in closed, partly in open form, for Loops around the head and neck or around the two auricles.

Compared to the multitude of proposals for folding material for making face masks and ear straps attachment has been less concerned with training the mask Hygienic face mask

give in order to achieve optimal filter effects and at the same time comfortable and easy to wear to achieve. For this purpose, a dense, but breathable material had to be used, which is in is able to also contain solid fine components, e.g. B. in smoke and vapors, from penetrating into the Keep respiratory tract. In addition to the suggestion mentioned at the beginning, in several layers of paper or Arranging fabric strips, however, are so far no special design proposals in this direction or forms became known.

It is now part of the state of the art to consolidate carded, loose fiber structures with binders and so make a non-woven material. It is further known by certain working procedures Such non-woven material is smooth on one side and roughened, fluffy or fluffy on the other to execute.

According to the invention it is now proposed that two fluffy on one side and the fluffy Side of each other lying fiber fleece strips are arranged and to adapt to the facial contours are folded. This fluffy formation creates a certain fiber-filter pad that is important for the filter effect created between the two fleece strips.

The two outward-facing surfaces of the face mask are also those facing the face soft and smooth and ensure a comfortable, skin-friendly wearing for the user. In this context, it no longer depends on the special formation of the fold, but it is any suitable fold depending on the shape of the face and the numerous uses for it suitable.

Claims (2)

By merging two nonwovens with a rough surface on one side and a smooth surface on one side, a surprising filter effect with good breathability is achieved. In addition, a protective mask can be produced in this way which, due to the material, is conceivable in its production costs. is low. However, this is essential in order to form a mouthguard that is only intended for single use and to avoid repeated use for reasons of hygiene. The advantages of the use according to the invention of two folded fiber nonwovens placed one against the other with different surface properties can be further increased by arranging inserts, equipped with fragrances and active substances, between these two layers. Such inserts can, for example, also develop an absorption and inhalation effect. It is also within the scope of the present invention to use inserts with, inter alia, an antibacterial disinfectant effect. In detailed experimental investigations with the novel material, as it is the subject of the above invention, for the production of a hygienic mouthguard which can be sterilized, it can be clearly stated that this creates a good barrier for breathing, which prevents the passage of germs. This is particularly true in comparison to the conventional and known, woven and mostly heavy mouthguard cloths, which on top of that have to be washed and sterilized in each case. Patent claims: 1. Single-use face mask, consisting of lengthways nonwoven folded several times and tied with fastening tapes at the ends Nonwoven strips, characterized in that that two one-sided fluffy and with the fluffy side to lie to each other fiber fleece strips arranged and folded to adapt to the contours of the face. 2. Face mask according to claim 1, characterized in that between the longitudinally folded, doubled, non-woven fiber fleeces with a fluffy texture facing each other Deposits with fragrances or active ingredients are introduced for inhalation or disinfection purposes when wearing the face mask and breathing deeply.
