Description

Die Erfindung betrifft eine Anordnung einer Sicherheitseinrichtung an einer Sprühdose, insbesondere für Farben, Lacke, Haarspray od. dgl., mit einem nach außen führenden, oberhalb der Stehfläche des Dosenbodens liegenden Überdruckventil.The invention relates to an arrangement of a safety device on a spray can, in particular for paints, varnishes, hairspray or the like., with one after outside leading overpressure valve above the standing surface of the can bottom.

Bei bekannten Sprühdosen ist nachteilig, daß diese bei Erreichen eines zu hohen Innendruckes platzen können.Known spray cans have the disadvantage that they can burst when too high an internal pressure is reached.

Dieses Platzen erfolgt meist dann, wenn die Sprühdose in gefülltem Zustand einer zu hohen Temperatur, die beispielsweise schon durch Sonneneinstrahlung gegeben sein kann, ausgesetzt wird. This bursting usually occurs when the spray can is too high when it is full Temperature that can already be given by solar radiation, for example.

Durch die hohe Temperatur expandiert insbesondere das in der Sprühdose enthaltene Druckmittel, wodurch die Sprühdose knallartig platzen kann.As a result of the high temperature, the pressure medium contained in the spray can in particular expands, as a result of which the spray can can burst.

Die Ventileinrichtung nach der US-PS 30 11 686 weist zwar ein Überdruckventil auf, das bei zu hohem Druck im Behälter öffnet: bei der Montage dieses Ventils müssen aber Teile von innen und andere Teile vonThe valve device according to US-PS 30 11 686 has a pressure relief valve that opens when the pressure in the container is too high: when this valve is installed but need parts of the inside and other parts of

ίο außen durch den Dosendeckel gesteckt und dann miteinander verbunden werden.ίο put through the socket lid on the outside and then be connected to each other.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Sicherheitseinrichtung zu schaffen, welche eine Standardsprühdose mit geringem Aufwand gegenüber Explosion sichert und den Gebrauchswert nicht mindert, zugleich billig und einfach im Aufbau ist.The invention is therefore based on the object of creating a safety device which uses a standard spray can secures against explosion with little effort and does not reduce the utility value, is cheap and easy to build at the same time.

Diese Aufgabe wird dadurch gelöst, daß das Überdruckventil an dem Dosenboden angeordnet ist und sich mit einer Schulter seines Ventilgehäuses an der Innenseite des Dosenbodens abstützt.This object is achieved in that the pressure relief valve is arranged on the bottom of the can and is supported with a shoulder of its valve housing on the inside of the can bottom.

Die Erfindung hat den Vorteil der einfachen Montage, es muß nur das Überdruckventil von innen in den Sprühdosenboden eingesteckt werden, so daß es sich mit einer durch eine Erweiterung auf einen größeren Außendurchmesser gebildenten Schulter von innen auf den Dosenboden abstützt.The invention has the advantage of simple assembly; only the pressure relief valve has to be inserted from the inside Aerosol base can be plugged in so that it can be dealt with by an extension to a larger one Outer diameter formed shoulder is supported from the inside on the bottom of the can.

Diese Erweiterung hat zur Folge, daß das Ventil bei üblichen Standard-Sprühdosen, vgl. z. B. die Fig. 4 auf Seite 83, von »Elsevier's Lexicon of Pressurized Packaging« 1964, nicht im Deckel neben den anderen Ventileinbauten, sondern nur im Boden der Sprühdose unterzubringen ist.The consequence of this expansion is that the valve in conventional standard spray cans, cf. B. Fig. 4 on Page 83, from Elsevier's Lexicon of Pressurized Packaging 1964, not in the lid next to the others Valve fixtures, but only to be accommodated in the bottom of the spray can.
