Abstract (en)
1. A safety container (1) with flexible compressible container walls, more particularly for the dispensing of easily inflammable materials, the opening of which is closed by a safety closure firmly seated on a container projection, and a removable cover cap (8), the safety closure consisting of a diaphragm controlled conical valve (7) actuated by reduction of the internal volume of the container, a diaphragm (16) of said valve having a centrally disposed opening (17) with a sealing rim through which a valve cone (20) extends and against which the sealing rim engages, and which furthemore has a cylindrical diaphragm carrier formed on a margin thereof, the margin section remote from the diaphragm sealingly engaging the container extension, characterized in that the wall of the diaphragm (16) having the central opening (17) is conically tapered in the direction towards the container interior and is raised up outwardly in the form of a collar (19) and sealingly engages on the valve cone (20), which for its part is arranged on an annular plate fitted resiliently yieldably in the diaphragm carrier (12) and provided with cutouts.

Beschrieben ist ein Sicherheitsbehälter zum Ausgeben von leicht entflammbaren Flüssigkeiten, der aus flexiblen, komprimierbaren Behälterwänden und einem durch eine Abdeckkappe verschliessbaren Sicherheitsventil besteht, das als membrangesteuertes Kegelventil (7) ausgelegt ist. Die Membran (16) weist eine mittige, durch einen Dichtrand begrenzte Ausnehmung (17) auf, durch die ein Ventilkegel (20) gesteckt ist, an dem der Dichtrand angliegt. Betätigt wird das Kegelventil durch Zusammendrücken der flexiblen Behälterwände und damit Verkleinerung des Innenraumes des Behälters und Erhöhung des Innendruckes.
