专利说明:

The invention relates to a face mask for covering areas of a face, comprising - at least one mask body with at least one nose recess for accommodating a nose of the face and at least one mouth cover with which a mouth of the face can be covered, - at least one holding means for fastening the face cover to a Head, in particular on one ear, - wherein the face mask consists of a transparent material at least in regions, preferably completely. Furthermore, the invention relates to an arrangement of at least one such face mask and at least one storage device and one
Process for producing at least one such face mask.
In order to be able to ensure an improved sterility environment by reducing pathogens such as germs, bacteria or viruses in the ambient air, it is generally known from the prior art to attach transparent face shields to potentially infected persons, in particular when they cough or sneeze
increased aerosol and/or droplet distribution into the ambient air is inhibited.
A disadvantage of such face shields, however, is that the distribution of aerosols and/or droplets into the ambient air cannot be suppressed to a sufficient extent, since there is essentially no lateral barrier between the person's face and the face shield. In addition, face shields are bulky even with moderate everyday movements and due to the large sizes required
uncomfortable to transport.
Commercially available face masks made of fabric have the disadvantage that an area of the facial area - in particular the mouth - is visually obscured, which is detrimental to communication, since facial expressions during a conversation and in non-verbal communication are essential for an exchange of information between people. In front
especially for the deaf, mute, hard of hearing or people in high noise environments
Noise pollution are such face masks a major obstacle that the
Communication severely affected by the optical limitation.
A generic face mask is already known from WO 2018/140841 A1, in which transparent plastic films are used to cover the mouth and nose during medical treatments
obtain and allow access points for intubation.
A disadvantage of the prior art is that the face mask's service life is reduced by the plastic film and is not suitable for regular use. Furthermore, wearing comfort is reduced when wearing glasses, since exhaling warm and/or moist breathing air results in the glasses fogging up. In addition, breathing air can condense on the plastic film, which means that the face mask fogs up and transparency can only be maintained to a limited extent. Furthermore, cleaning the face mask through instability of the plastic film is uncomfortable and ineffective, as well as maintaining a tight fit on the face by repeatedly and tediously adjusting the face mask
must become.
The objective technical task of the present invention is therefore to specify a face mask that is improved over the prior art, in which the disadvantages of the prior art are at least partially eliminated, and which is characterized in particular by easy cleaning, high wearing comfort, reduced tendency to fog up enhanced by condensation as well
Distinguished communication properties when wearing the face mask.
This object is solved by the features of claim 1.
It is therefore provided according to the invention that at least the at least one
Mask body is made from an injection molded part.
This makes it possible that the face mask through the
Material-specific properties of injection-moulded materials include rigidity
and/or has robustness, which requires a comfortable cleaning of the face mask with repeated wearing of the face mask as well as a firm fit on the face, whereby a frequent adjustment of the face mask relative to the face
is no longer required.
In addition, there is the positive property that the face is essentially freely visible due to the transparency, in particular in combination with a high stability, of the face mask, as a result of which communication is facilitated while the face mask is being worn. For those who are deaf, mute, hard of hearing and/or, for example, factory workers in environments with high noise levels
This makes it easier to transport information content from person to person.
Furthermore, individualization and/or precision in the production of the face mask is increased since injection molds can be individually adapted to the desired geometry of the face and inaccuracies caused by production can be reduced. Manual production steps can be kept to a minimum
be reduced, which saves human resources.
As stated above, protection is also sought for an arrangement of at least one such face mask and at least one storage device, which is preferably designed in the form of a bag and in which the at least one
Face mask is detachable during non-use.
The at least one storage device prevents contamination of the at least one face mask and/or offers protection against damage such as scratching of the at least one transparent mask body during transport and/or storage. In addition, the at least one storage device can be personalized and/or provided with a visually appealing design in order to improve the aesthetic appearance and/or to reduce the risk of confusion with other storage devices or face masks. In general, the at least one storage device can, for example, have means for attachment to a backpack
have for more comfortable transport.
As stated at the outset, protection is also sought for a method for producing at least one such face mask, in which at least the at least one mask body is produced in an injection molding process, preferably in which the at least one mask body is provided with at least one discharge shield, at least one spacer, at least in a further process step a nose bed, at least one microphone and/or the at least one holding means, preferably
detachable, is connected.
The production of at least one face mask can be fully automated or
be carried out semi-automatically.
A particular advantage of the face mask is that the individual components of the face mask can be assembled and/or disassembled essentially without technical expertise in order, for example, to attach a nose bed of varying geometry and/or a holding means of changed length to the face mask. This allows the face mask to be individually adapted to the
present requirements can be adjusted.

in a lateral area of the mask, in which at least one temporary

In general, the face mask can also have a filter in the mask body, which makes it easier to breathe in and/or out while wearing the face mask. However, the breathing air is particularly preferably diverted to areas of the face mask that are essentially irrelevant for communication, in order to reduce or prevent fogging due to condensation in the areas of the face mask relevant to communication and to prevent contaminated aerosols and/or droplets in the breathing air from escaping reduce or prevent. In general, there are also locking elements — for example, in the form of silicone barriers, which adapt to the shape of the face

face — to be derived.
Breathing air transport can be generated in a particularly favorable manner by at least one deflection shield which is arranged centrally on the face mask and/or is present in a triangular shape.

particularly safe face mask is given.
The face mask can be used for marketing purposes via the at least one personalizable area and/or with one's own name, for example
be provided for identification.
Polycarbonate has proven to be particularly favorable for use in face masks because density and air permeability are low, durability and transparency are high, and polycarbonate is a biocompatible material that does not emit toxic fumes and is kind to the skin. In general, however, other plastic compositions and/or transparent materials are also conceivable, with the face mask not being restricted to polycarbonate, with mixtures of polycarbonate with various, for example, also being possible
additives are possible.

FIG. 2c shows the mask body 2 according to FIG. 2 rotated through 90 degrees in a plan view from above. The mask body 2 has two tabs 31 on both sides
which the two straps 26 are placed in the assembly of the face mask 1.
At the position at which the nose bed 22 is arranged, the mask body 2 has snap-in elements into which the nose bed 22 is inserted and in which the nose bed 22 is held in a non-positive manner by elastic deformation of the nose bed 22 during insertion via a non-positive connection 38.

Fig. 1b). Due to the concave curvature 13, breathing air can be deflected downwards from the deflection shield 10 in the position of use 21 of the face mask 1, so that a
