Abstract

The reliable spray can is operated by compressed air. The top of the can is designed to be unscrewed and has a spray valve. A movable hollow piston (5) forms a two-chamberr system. In the bottom of the can there is pref. a non-return valve designed as a filling valve (V1) with a rubber bead. By pressing the compressed air gun the can can be pumped up at the bottom of the hollow piston with the usual pressure of 8-12 bar. The volume of the compressed air chamber must be large enough so that the pressure on the piston is sufficient right into the last emptying phase. USE/ADVANTAGE - The spray cans can be easily refilled and are reliable to use through compressed air. They are suitable for industrial and workshop use.

Description

Stand der TechnikState of the art

Auf dem Markt gibt des Sprühdosen in vielfältiger Ausführung, die mit dem Treibgas FCKW oder umweltfreundlichen Treibgasen betrieben werden.There are spray cans on the market diverse execution with the Propellant CFC or environmentally friendly Propellants are operated.

Kritik an der TechnikCriticism of the technology

Die bisherigen wiederbefüllbaren Sprüh­ flaschen sind durch den manuellen Pump­ betrieb nicht befriedigend.The previous refillable spray bottles are through the manual pump operation unsatisfactory.

Die Zweikammer-Sprühdosen als Einwegarti­ kel sind auch nicht befriedigend.The two-chamber spray cans as disposable items kel are also not satisfactory.

Aufgabetask

Der Erfindung liegt die Aufgabe zugrunde, daß Werkstätten und Industriebetriebe immer wieder Sprühdosen mit unterschiedlichen Füll­ gütern einsetzen können und diese Sprühdosen leicht und schnell mit Druckluft als Treibmit­ tel über die in diesen Betrieben üblicherweise verfügbaren Druckluftanschlüsse befüllt werden können. The invention is based on the object that workshops and industrial companies always again spray cans with different filling can use goods and these spray cans easily and quickly with compressed air as a propellant tel about the usual in these companies available compressed air connections can.  

Lösungsolution

Diese Aufgabe wird dadurch gelöst, daß die Sprühdose einen abschraub­ baren Kopf mit Sprühventil erhält, sowie einen beweglichen, einsetzbaren Hohlkolben.This task is solved by that the spray can unscrew one obtainable head with spray valve, as well as a movable, usable Hollow piston.

Im Boden der Dose befindet sich ein Rückschlagventil als Füllventil mit einer Gummiwulst.There is a in the bottom of the can Check valve as a filling valve with a rubber bead.

Durch Andrücken der Druckluftpistole läßt sich die Dose im unteren Bereich des Hohlkolbens (Zweikammer-System) leicht mit dem üblichen Druck von 8- 12 bar aufpumpen.By pressing the compressed air gun the can is in the lower area of the hollow piston (two-chamber system) easily with the usual pressure of 8- Pump up to 12 bar.

Das Volumen der Druckluftkammer muß groß genug gewählt sein, damit der Druck auf dem Kolben auch bis in die letzte Leerungsphase ausreichend ist.The volume of the compressed air chamber must be chosen large enough so that the Pressure on the piston also into the last emptying phase is sufficient.

Ein zweites Ventil im Boden der Dose ist als Sicherheits-Überdruckventil und Entlüftungsventil ausgelegt. Als Entlüftungsventil deswegen, damit die Dose im drucklosen Zustand geöffnet werden kann und der Kolben auch in seine Endposition nach unten zu drücken ist.A second valve in the bottom of the can is as a safety pressure relief valve and vent valve designed. As Vent valve so that the Can open when depressurized  can be and the piston also in to push its end position down is.

Durch die Vielfachverwendung der wieder­ befüllbaren Sprühdosen ist das Entsor­ gungsproblem mit häufig gefährlichen Rest­ mengen deutlich verringert.Due to the multiple use of the again fillable spray cans is the disposal problem with often dangerous rest quantities significantly reduced.

Weitere Ausgestaltung der ErfindungFurther embodiment of the invention

Bei Sprühprodukten, welche sich nach län­ gerem Stehen absetzen und vor Gebrauch aufgeschüttelt werden müssen, kann der Hohl­ kolben herausgezogen werden und eine Kugel zum Aufrühren durch Schütteln eingelegt wer­ den.In the case of spray products that vary according to length Lower standing and before use can be shaken up, the hollow pistons are pulled out and a ball to stir by shaking the.

Anstelle des Hohlkolbens (Zweikammer-System) kann ein Steigrohr (Einkammer-System) am Sprühventil eingesetzt werden.Instead of the hollow piston (two-chamber system) can a riser pipe (single chamber system) on Spray valve can be used.

Es ist darauf zu achten, daß im Einkammer­ systembetrieb die Dose nur so weit mit Nutz­ füllgut befüllt wird, daß ein ausreichendes Volumen für die Druckluft als Treibmittel verfügbar ist. Care should be taken that in the unicameral system operation the can only so far with useful filling is filled that a sufficient Volume for the compressed air as a blowing agent is available.  

Die Druckluftbefüllung findet wie beim Hauptanspruch über das Bodenventil statt.The compressed air filling takes place like the main claim about that Bottom valve instead.

Die Entlüftung hat in Über-Kopf­ stellung der Spraydose zu erfol­ gen, damit nicht restliches Füll­ gut durch das Ventil austritt.The vent has overhead position of spray can so that there is no remaining filling exits well through the valve.

Weitere Ausgestaltung der ErfindungFurther embodiment of the invention

Für Haushalte und Betriebe ohne Drucklufteinrichtungen bietet sich an, daß zur Druckgasbefüllung der Sprühdosen die am Markt üblichen Gasdruckpatronen Anwendung finden mit den dafür üblichen Befüllungs­ ventilen.For households and businesses without Compressed air equipment is available at that for filling the gas Spray cans the usual on the market Find gas pressure cartridges with the usual filling valves.

Vorteileadvantages

Durch die Vielfachverwendung der wiederbefüllbaren Sprühdosen ist das ökologische Entsorgungsproblem mit häufig gefährlichen Restmengen deutlich verringert. Due to the multiple use of is refillable spray cans the ecological disposal problem with often dangerous residual amounts significantly reduced.

1. Wiederbefüllbare Sprühdose, die mit Druck­ luft betrieben wird, dadurch gekenn­ zeichnet, daß der Kopf mit dem Sprühventil zum Befüllen mit dem Nutzgut abschraubbar ist und ein beweglicher Hohlkolben das Zwei­ kammer-System bildet.
Bei der wiederbefüllbaren Sprühdose ist der Kopf mit dem Sprühventil zum Befüllen des Nutzgutes abschraubbar und ein beweg­ licher Hohlkolben bildet das Zweikammer- System, wobei vom Boden der Dose über ein Rückschlagventil mit einer werkstattübli­ chen Druckluftpistole die untere Kammer mit Druckluft als Treibmittel befüllt wird. Dieses Druckluftpolster erzeugt durch den Kolben getrennt einen Druck auf das Nutz- Füllgut, was durch Betätigen des Ventiles versprüht wird.
