Description

  

      Haubenmaske    aus dehnbarem     Baustoff    wie Gummi,     Kunstgumml,          Polyvinylverbindungen    oder     dergl.    mit A     usatemventil.       Gegenstand der Erfindung ist eine Hau  benmaske aus dehnbarem Baustoff wie  Gummi, Kunstgummi,     Polyvinylverbindun-          gen    oder     dergl.    mit     Ausatemventil,    die sich  dadurch auszeichnet,     dass    der Maskenkörper  an der für das Ventil vorgesehenen Stelle als  Ventilteil ausgestaltet ist.  



  Die Zeichnung zeigt zwei beispielsweise  Ausführungsarten des Gegenstandes der Er  findung. In     Fig.   <B>1</B> ist die Haubenmaske mit<B>1</B>  bezeichnet. Eine Stelle des Maskenkörpers ist  als     Ventilsitz    für einen als Membran 2 aus  gebildeten Ventilteller ausgestaltet.

   Die     Mein-          bran    2 ist mittels mehrerer Zipfel 4 am Mas  kenkörper<B>1</B> angeklebt.     Fig.    2 zeigt eine  andere Ausführungsform, bei der das     mein-          branartige        Verschlussorgan    2 am grössten Teil  seines Umfanges am Maskenkörper zusam  menhängend     angehlebt    ist und so eine Tasche  bildet, aus der die abströmende Luft nach  unten hin austreten kann. Die Pfeile deuten    die     Ausströmungsrielitung    der     Ausatem-          luft    an.  



  Die Wandteile des Maskenkörpers, an die  sieh die Ventilmembranen anlegen, können  verstärkt oder versteift ausgebildet sein. Die  Ventilmembran kann an den Maskenkörper  angeklebt oder     anvulkanisiert    sein.



      Hood mask made of elastic building material such as rubber, synthetic rubber, polyvinyl compounds or the like. With an exhalation valve. The subject of the invention is a hood made of stretchable building material such as rubber, synthetic rubber, polyvinyl compounds or the like. With an exhalation valve, which is characterized in that the mask body is designed as a valve part at the point provided for the valve.



  The drawing shows two exemplary embodiments of the subject matter of the invention. In FIG. 1, the hood mask is labeled with <B> 1 </B>. One point of the mask body is designed as a valve seat for a valve disk formed as a membrane 2.

   The membrane 2 is glued to the mask body <B> 1 </B> by means of several tabs 4. FIG. 2 shows another embodiment in which the mybelike closure member 2 is attached to the mask body in a cohesive manner over most of its circumference and thus forms a pocket from which the outflowing air can exit downwards. The arrows indicate the outflow direction of the exhaled air.



  The wall parts of the mask body against which the valve membranes are attached can be reinforced or stiffened. The valve membrane can be glued or vulcanized onto the mask body.
