Description

Protective mask for absorbing the wearer's breathed air from the inside, which is contaminated by bacteria, as well as protecting it from outside bacteria, viruses and pollen for use in everyday work and in leisure time by adults and children.

A large number of protective masks for medical and other areas of use are known. These are characterized in particular by complex, expensive constructions, shapes, materials for special areas of use and complex maintenance procedures, and simpler shapes that are difficult to manufacture, washable or, in some cases, can only be used once.

The pamphlet DE 1 962 588 U1 discloses a protective mask to prevent infection and transmission of pathogens (for example colds, flu, etc.). The main task of the protective mask is to be versatile, especially in the family (nursing mothers), the use of materials being inexpensive, the protective mask being disposable after each use and easy handling. The protective mask claims an oval, square and in every way face-appropriate shape. The exemplary embodiments consist of fabric that has a hem at the top and bottom through which a rubber ring is drawn, which forms a loop on both sides and is pulled over the auricles and the mask is held over the nose and mouth. Instead of rubber, a textile tape, wire or plastic can also be used, which can also be tied around the neck. In order to achieve a good fit over the face, the fabric is placed in folds and sewn on the edge. A variant is also described in which the paper or other protective material is placed in a net which ends in holding loops that can be placed over the auricles. The protective material and the holder are separate.

The disadvantage of these embodiments is a high manufacturing cost, due to cutting, sewing or gluing, pulling in holding parts, etc. The use of rubber parts for the holder, especially when using separate, mesh material, in which an insert must be arranged again the protective mask made of mesh material is pushed together. This variant entails laborious handling when putting on the mask and when using it because the protective material can be moved when the face is moved, for example when speaking, coughing and sneezing, etc.

It was therefore an object of the present invention to provide a protective mask for absorbing the wearer's breathed air from the inside and its protection against bacteria, viruses and pollen from the inside, for use in everyday life at work and in leisure time by adults and children Can be manufactured inexpensively, can be manufactured from a stretchable but elastic material that is odorless, free of plasticizers, disinfected in washing machines and in the oven and can therefore be reused as required.

The object is achieved, according to claim 1, in that the basic framework, cast in one piece, consists of a soft, flexible and stretchable plastic material and is made in one piece in a flat shape, the upper and lower frame parts of which are arranged horizontally one above the other by vertically spaced apart between them Longitudinal webs are connected to one another and which form a coarse-meshed grid on which on both sides, horizontally, symmetrically opposite, one ear tab and, alternatively, at least one receiving eyelet is formed.
The advantage of this basic structure is that the basic shape of the coarse-meshed lattice can be stretched in its height above the nose and chin and in its width up to the ears and the facial contours of the wearer, without the lattice structure collapsing when the mask is removed. This is achieved through the soft, flexible and stretchable plastic material used. It ensures that the basic framework always returns to its starting position even after stretching and that it retains a constant, unchanged, stable basic shape and that it can be manufactured and used inexpensively by machine and in one piece and without reworking.

The protective mask, according to claim 2, allows the basic structure, cast in one piece, to be equipped with additional horizontally molded cross-bars in the middle of the horizontally stacked upper and lower frame parts above the nose and chin of the wearer.
It should be emphasized here that any filter part to be manually inserted between the wearer's face and the basic structure must be fixed in the middle above the wearer's nose and chin. This structure of the protective mask allows a stable and non-displaceable mounting of the filter part between the face and the basic structure. Furthermore, the filter part can be changed frequently and disposed of together with the bacteria, viruses and other pathogens that have been absorbed from the inside and outside and exchanged for a new or cleaned and unused filter part.

The construction is particularly advantageous, according to claim 3 and 4, by separating the molded ear flaps and replacing them with the Alternatively, any detachable fastening elements can be arranged manually, hung behind the ears or tied together behind the head, and that the separate filter part can be made of any material, such as fleece, textile fabric, cellulose and similar material, is air-permeable and closely meshed .
This alternative construction allows the manual assembly of fasteners made of simple string, elastic or cloth, etc., which can be tied or held together behind the ears or at the back of the head. This enables optimal adaptation to different sizes and shapes of a wearer's head, for example also for children. This form of fastening means also ensures that the long-term reusability of the basic structure, its cleaning and disinfection and the regular interchangeability of the contaminated filter parts and their disposal. Handkerchiefs and kitchen towels made of fabric, cellulose or paper, as well as cotton scraps can be used as filter parts.

Finally, according to claim 5, the plastic material of the basic structure preferably consists of TPU hardness 85 Shr. A. This material is stretchable and elastic, odorless, free from plasticizers and in washing machines up to 60 ° or 30 minutes. Can be disinfected in the oven at 80 ° and can therefore be reused as required. In addition, it can be produced in different colors and thus adapted to any fashion requirements and wishes.

• 2 the front view of 1 of the main body with ear flaps and eyelets in stretched form,
• 3 the front view of 1 and 2 the device according to the invention with an underlying filter part,
• 4th the front view of 1 and 2 of the base body according to the invention without ear tabs with receiving eyelets and fastening elements.

In the first embodiment, according to 1 and 2 , is a basic structure 1 the protective mask in its basic form and in a stretched state. It is preferably made of plastic material 2 , TPU hardness 85 Shr. A. The framework 1 is produced in one piece in a flat shape, for example by injection molding. The basic size was chosen, for example, at a length of 34 mm, width between 7.5 mm on both sides at the edge and in the middle of 11.5 mm and the thickness of the material of preferably 1.5 mm. According to 3 is now on the lower surface of the base body 1 a filter part 5 , for example a cellulose handkerchief. Both parts are placed on the face over the nose and under the chin of the wearer and the base body 1 as well as the ear tabs 3 stretched in the horizontal direction so that they adapt to the contours of the face and can be hung behind the respective ear cups of the wearer.
In a second embodiment, according to 4th will be the ear tabs 3 from the main body 1 cut off with scissors, for example. For example, to be used on a child in the loops 4th opposite fastening elements 3 , for example thin fabric or rubber bands knotted and tied behind the head. The fasteners 3 can be made of a rubber band, both ends of which are attached to the mounting eyelets 4th are knotted. The main body with the filter part underneath 5 can easily be pulled over the child's head and directed at the face so that the child's nose and chin are covered.
