  • In der Figur 1 ist in einer Teilansicht ein Druckgasbehälter 1 mit einem geschlossenen Abgabeventil 2 dargestellt. 1 shows a partial view of a compressed gas container 1 is shown with a closed dispensing valve. 2 Der Druckgasbehälter 1 gestattet ein getrenntes Aufbewahren einer schaumbildenden ersten Flüssigkeit 3 und einer zweiten Flüssigkeit 4 und ein dosiertes Abgeben beider Flüssigkeiten 3, 4 mittels des Abgabeventils 2, das ein erstes Ventil 5 und ein zweites Ventil 6 aufweist. The pressure gas container 1 allows a separate storage of a foam-forming first liquid 3 and a second liquid 4 and a metered dispensing of both liquids 3, 4 by means of the discharge valve 2, which has a first valve 5 and a second valve. 6 Das Abgabeventil 2 ist mit einem Expansionsabschnitt 7 zur Schaumbildung und zum Transport von Schaum 8 (Figur 2) versehen. The dispensing valve 2 is provided with an expansion section 7 for foam formation and for the transportation of foam 8 (Figure 2). Die zweite Flüssigkeit 4 ist von einem komprimierbaren Innenbehälter 9 aufgenommen. The second fluid 4 is received by a compressible inner container. 9 In diesem Ausführungsbeispiel ist der Innenbehälter 9 zylindrisch ausgestaltet und mit einem vom Innendruck des Druckgasbehälters 1 beaufschlagbaren Kolben 10 versehen, wodurch die zweite Flüssigkeit 4 unter Druck steht. In this embodiment, the inner container 9 is cylindrical in shape and provided with a loadable from the internal pressure of the gas cylinder 1 piston 10, whereby the second liquid is 4 under pressure. Der ersten Flüssigkeit 3 ist das erste Ventil 5 und der zweiten Flüssigkeit 4 das zweite Ventil 6 zugeordnet, wobei ein erster Kanal 11 des ersten Ventils 5 und ein zweiter Kanal 12 des zweiten Ventils 6 in einen Anfangsbereich 13 des Expansionsabschnitts 7 eines Ventilstößels 14 mündet. The first liquid 3 is assigned to the second valve 6 the first valve 5 and the second liquid 4, wherein a first channel 11 of the first valve 5 and a second channel 12 of the second valve 6 in an initial portion 13 of the expansion section 7 of a valve lifter 14 opens. Das Abgabeventil 2 besteht aus einem ersten und zweiten Ventil 5, 6 mit jeweils einer elastischen Dichtscheibe 15, 16. Zum axialen Betätigen des Ventilstößels 14 ist dieser - wie gestrichelt angedeutet - mit einem Betätigungsaufsatz 17 versehen. The dispensing valve 2 consists of a first and second valve 5, 6, each having a resilient sealing disc 15, 16. To the axial actuation of the valve stem 14 of this - as indicated by broken lines - provided with an operating attachment 17th Dieses Ausführungsbeispiel ist für ein kopfstehendes Applizieren vorgesehen. This embodiment is provided for applying an upside down. Jedoch kann auch ein entgegengesetztes Applizieren durch eine dazu geeignete Steigrohranordnung (nicht dargestellt) für die erste Flüssigkeit 3 vorgesehen werden. However, also an opposite applying thereto by a suitable riser assembly (not shown) may be provided for the first liquid. 3
  • In der Figur 2 ist der Druckgasbehälter 1 während einer Abgabe der beiden Flüssigkeiten 3, 4 mittels axialen Drucks auf den Betätigungsaufsatz 17 dargestellt. In the figure 2, the pressure gas container 1 during a dispensing of the two liquids 3, 4 displayed on the operation cap 17 by means of axial pressure. Durch diesen Druck wird der Ventilstößel 14 axial bewegt, wodurch in etwa zeitgleich die beiden Dichtscheiben 15, 16 des ersten und des zweiten Ventils 5, 6 von ihrem Dichtsitz angehoben werden und sich dadurch öffnen, wodurch die erste Flüssigkeit 3 durch den ersten Kanal 11 in den Anfangsbereich 13 des Expansionsabschnitts 7 fließt (und sogleich sich zu einem Schaum 8 ausbildet) und die zweite Flüssigkeit 4 über einen ersten Verbindungskanal 18 und einen zweiten Verbindungskanal 19 durch den zweiten Kanal 12 in den Anfangsbereich 13 des Expansionsabschnitts 7 fließt, wobei der zweite Kanal 12 peripher an einer Innenwand 20 des Expansionsabschnitts 7 mündet und sich dadurch als ein Randstreifen 21 zum Schaumstrang 8 ausbildet. By this pressure, the valve plunger 14 is moved axially, whereby in about the same time, the two sealing disks 15, 16 of the first and second valves 5, are lifted 6 from its sealing seat and thereby open, whereby the first liquid 3 through the first channel 11 in the top portion 13 of the expansion section 7 flows (and immediately is formed into a foam 8) and the second liquid 4 via a first connecting duct 18 and a second connecting channel flows 19 through the second channel 12 in the top portion 13 of the expansion section 7, wherein the second channel 12 peripherally terminates at an inner wall 20 of the expansion section 7 and is formed as a by an edge strip 21 to the foam strand. 8 Durch Aufheben des Drucks auf den Betätigungsaufsatz 17 werden wieder beide Ventile 5, 6 geschlossen. By releasing the pressure on the actuator cap 17, both valves 5, 6 are closed again. Beispielsweise kann der Druckgasbehälter 1 für Haarbehandlungen verwendet werden, wobei die erste Flüssigkeit 3 ein Basismittel und die zweite Flüssigkeit 4 ein - wahlweise farbiges - Zusatzmittel ist, das nicht aufschäumt. For example, the compressed gas container 1 can be used for hair treatment, wherein the first liquid 3, a base means, and the second liquid 4 a - is additive which does not foam up - optionally colored.
  • Eine Draufsicht III-III nur auf den Ventilstößel 14 mit dem einen peripher angeordneten zweiten Kanal 12 ist in der Figur 3 dargestellt. A plan view of III-III only at the valve stem 14 with a peripherally disposed second channel 12 is shown in FIG. 3
  • Nach der Figur 4 können aber auch - als Weiterbildung nach der Figur 3 - vier peripher gleichmäßig verteilte zweite Kanäle 12 vorgesehen werden. four circumferentially uniformly distributed second channels are provided 12 - according to the figure 4 but may also - as a further development according to FIG. 3 Ein großer Vorteil ist darin zu sehen, daß von entsprechend gefärbten Randstreifen 21 von allen Betrachtungswinkeln zumindest ein Randstreifen 21 sichtbar ist. A great advantage is to be seen in that at least one edge strip 21 of appropriately colored edge strip 21 is visible from all viewing angles.
  • Anstelle des einen exzentrisch angeordneten zweiten Kanals 12 nach der Figur 3 kann ein zentrisch angeordneter Kanal 12 nach der Figur 5 vorgesehen werden. Instead of an eccentrically disposed second channel 12 according to FIG 3, a centrally arranged channel 12 may be provided according to FIG. 5
  • Anstelle des einen Kanals 12 nach der Figur 5 können mehrere in etwa zentrisch angeordnete Kanäle 12 nach der Figur 6 vorgesehen werden oder auch in wahlweiser Kombination miteinander (zum Beispiel die Kanäle 12 nach der Figur 4 mit den Kanälen 12 nach der Figur 6). Instead of a channel 12 according to FIG 5, a plurality centrally arranged in such channels can be provided 12 to the Figure 6 or in optional combination with each other (for example, the channels 12 according to the figure 4 with the channels 12 according to FIG 6).
  • Wahlweise kann auch ein vom Innendruck des Druckgasbehälters 1 zusammendrückbarer - nicht dargestellter - Innenbehälter 9 vorgesehen werden. not shown - - inner container 9 are provided Optionally, a compressible by the internal pressure of the pressure gas container 1 can.
  • Es kann auch vorgesehen werden, den Expansionsabschnitt 7 so auszubilden, daß der Schaumstrang 8 wendelförmige Randstreifen der zweiten Flüssigkeit 4 aufweist, zum Beispiel mittels einer innenseitigen Wendelführung (nicht dargestellt). It can also be provided, the expansion section 7 so as to form the foam strand has 8 helical edge strips of the second liquid 4, for example by means of an inside helical guide (not shown).
