   Die Zwischenglieder der Ernenerungspatronen für Atmunsvorrichtungen bestehen zumeist aus einem Behälter, vorzugsweise aus einer Blechschale, und aus einem Drahtnetzdeckel. Um zu verhindern, dass die in der Schale ausgebreiteten Stoffe beim Kippen der Schale nach einer Seite rutschen, wodurch die Wirksame Oberfläche der chemischen Schicht in unerwünschter Weise verringert werden. würde. hat man bereits vorgeschlagen, die   Schalen durch Trennwände (Rippen, Leisten oder dgl. ) in einzelne Fehler zu teilen.   



   Der Gegenstand der   Erfindung besteht nnn darin,   zu dem gleichen Zwecke nicht die Schalen mit Trennwänden zu versehen, sondern die Drahtnetzdeckel so auszugestalten, dass sie hineingebogene, in das Innere der Schalen reichende Rippen aufweisen. 



   Diese Neuerung bietet dem bekannten gegenüber wesentliche Vorteile, die sowohl in der Herstellung der Patronen wie auch in der technischen Wirkung liegen. Bei der Herstellung der mit Rippen versehenen Schalen macht sich nämlich der Übelstand bemerkbar,

 Trennwänden versehen sind, den Vorzug. dass sich Luftwirbel bilden, durch die eine innigere Berührung der Luft mit den Chemikalien erzielt wird. 



   Auf der Zeichnung ist die Erfindung beispielsweise veranschaulicht. Fig. 1 stellt eine solche Patrone im senkrechten Längsschnitt dar ; Fig. 2 zeigt ein mit   hineingebogencn   Rippen versehenes Sieb und Fig. 3 eine für das Sieb (Fig. 2) geeignete, trennwandlose Schale. 



   Jede Schale a von runder, ovaler oder langgestreckter Form aus   blechartigen,   gelochtem oder drahtnetzartigem Stoff ist mit einem   Drahtnetz !) abgedeckt. Die Innenseite   des Drahtnetzdeckels b ist durch eine Anzahl von   hineingebogenen Rippen   d in kleinere

   The intermediate links of the renewal cartridges for breathing devices usually consist of a container, preferably a sheet metal shell, and a wire mesh cover. In order to prevent the substances spread out in the bowl from sliding to one side when the bowl is tilted, as a result of which the effective surface of the chemical layer is undesirably reduced. would. it has already been proposed to divide the shells into individual defects by means of partitions (ribs, strips or the like).



   The subject matter of the invention consists in not providing the shells with partition walls for the same purpose, but rather in designing the wire mesh covers in such a way that they have ribs that are bent into the interior of the shells.



   This innovation offers significant advantages over the known, which are both in the manufacture of the cartridges and in the technical effect. In the production of the ribbed bowls, the disadvantage is noticeable,
 EMI1.2
 Partition walls are provided, the preference. that air vortices are formed, through which a closer contact of the air with the chemicals is achieved.



   The invention is illustrated for example in the drawing. Fig. 1 shows such a cartridge in vertical longitudinal section; FIG. 2 shows a sieve provided with ribs bent into it, and FIG. 3 shows a bowl without a partition wall suitable for the sieve (FIG. 2).



   Each bowl a of round, oval or elongated shape made of sheet-like, perforated or wire-mesh-like material is covered with a wire mesh!). The inside of the wire mesh cover b is made smaller by a number of ribs d bent into it
