  • Such a foam generation device is known on the market as "F2 Finger Pump Foamer” from Airspray®.
  • This foam generation device is connected to a container which in each case contains the liquid to be foamed in the foam generation device. The user takes this into the foam generation and / or actuation of this foam generation device Hand and creates the foam by pressing down the actuating head.
  • the foam production device sold by Airspray® is not suitable for use in the known single-lever or single-arm wall dispenser devices, since then the lever of the wall dispenser device is not reset sufficiently and the foam generation therefore does not function satisfactorily.
  • the invention is based on the object of further developing a generic foam generating device for use in single-arm or single-lever wall-mounted dispensing devices.
  • this object is achieved according to the invention in that the foam outlet channel ends on the outlet side in a section inclined by 55 ° to 75 °, preferably 65 °, in relation to the foam outlet channel, and in that a second, to the first, on the liquid pumping piston Spring acts in the same acting spring.
  • the foam generation device With the foam generation device further developed by these features, it is achieved that such a device can be used functionally in single-arm or single-lever wall dispensing devices.
  • the second spring creates an additional force which moves the actuating arm or lever of the dispensing device, which acts on the actuating head of the foam generating device, into its initial position after actuation.
  • the 55 ° to 75 °, particularly preferably 65 ° inclined end section of the foam outlet channel in cooperation with the backward movement of the actuation lever caused by the second spring, ensures that after actuation of the dispenser device, no foam drips from the outlet channel or no undesired "foam noses" arise or remain at the end of the foam outlet channel.
  • this foam generating device creates a foam that is extremely fine-bubble, creamy and particularly stable. Such a foam does not collapse so easily when applied to oily or oily skin.
  • the invention therefore provides that the foam generating device is part of a single-lever wall dispenser device.

  • a third stage 10 is followed by a cylindrical section of the air pump piston 4, which comprises a mixing chamber 11. In the direction of a foam guide channel 12, the mixing chamber 11 is closed off by a wall section 13 with a foam generating device 14 formed centrally therein, in this case a nozzle-like opening.
  • the foam generating device 14 can also consist of a sieve or two sieves arranged at a distance from one another.
  • the display guide channel 12 is formed on the foam generating device 14.
  • the mixing chamber 11 formed by the air pump piston 4 is encompassed by a lower cylindrical region of the actuating head 5, which is arranged in a depressible manner in a cylindrical region of the adapter 9.
  • there is a hollow liquid pump piston 15 which is aligned coaxially with the foam generating device 14 and which has its opposite end in the zy- Linden-shaped liquid pump chamber 3 is immersed.
  • the liquid pump piston 15 has star-shaped flange regions 17 which extend with their outer extent into the region of the first stage 6 and which lie flat against the annular disk valve 16 when the foam generating device in the figure shown starting position is.
  • the liquid pump piston 15 is surrounded below the flange regions 17 by a second spring 18, which, with its end facing away from the flange regions 17, rests on an upper peripheral edge of the liquid pump chamber 3 into which the liquid pump piston 15 is immersed.
  • a first spring 19 Arranged within the cylindrical liquid pump chamber 3 is a first spring 19 which bears against an annular flange end 20 of a hollow, cylindrical liquid inlet element 21 and the end of the liquid pump piston 15 which plunges into the liquid pump chamber 3.
  • the first spring 19 is dimensioned with respect to its length and spring force in such a way that it moves the liquid pump piston 15 and thus also the elements air pump piston 4 and actuating head 5 lying against it into the starting position shown in the figure and holds it against gravity.
  • Both the spring 18 and the spring 19 are a compression spring inside the hollow liquid pump piston 15, an inner rod 22 is arranged, which with conical sealing surfaces 23, which abut correspondingly conical sealing surfaces 24 of the liquid pump piston 15, the interior of the liquid pump piston 15 and the liquid pumping chamber 3 against the mixing chamber 11 in the illustrated starting position of the foam generating device.
  • the rod 22 With its opposite end, the rod 22 is immersed in the hollow liquid inlet element 21, the first spring 19 encompassing the area neither immersed in the liquid pump piston 15 nor in the liquid inlet element 21.
  • the end of the cylindrical liquid inlet element facing the liquid inlet opening 25 has slot-shaped openings 26 in the lower edge region of its side wall.
  • the liquid pump chamber 3 In the transition region between the liquid inlet opening 25 and the end of the liquid pumping chamber 3 which forms a step 27 for a stop of the annular flange end 20, the liquid pump chamber 3 has a conical region 28 which is designed as a check valve by means of a ball 29 arranged therein.
  • a riser pipe is connected to the liquid inlet opening 25 and extends to the bottom of the container containing the liquid to be foamed.
  • the actuating head 5 has a foam outlet channel 30 branching off at a right angle from the foam guide channel 12. This foam outlet channel 30 ends on the outlet side in a section 31 which extends outward at 65 ° (angle ⁇ ) with respect to the foam outlet channel 30.
  • the adapter element 9 has a cylindrical section 32, the wall of which engages in a sealing manner in the mouth of the container (not shown) containing the liquid to be foamed and bears against it.
