  • Such an article is such. B. known from DE 26 10 129 A2.
  • a vacuum valve is provided within the foam discharge channel for sucking in outside air into the air bellows. Due to the air bellows, the foam generating device is shake-proof, which means that no foam generation impairment can occur by shaking the attachment with the container, but when external air is sucked in, part of the foam or liquid remaining in the discharge channel penetrates into the container Air bellows.
  • the aim is to ensure that the liquid collecting in the air bellows has no harmful influence on the foam generation.
  • the liquid that accumulates more and more leads to a reduction in the air volume of the bellows, which is particularly disadvantageous in the case of refillable containers. Providing a correspondingly larger bellows would mean a reduction in the usable volume.
  • a major disadvantage arises when the liquid to be foamed hardens on evaporation, for example through the addition of resin to a hair care product, which leads to a functional impairment of the bellows due to the air exchange in the bellows, since the bellows cannot then be compressed unhindered.
  • Another major disadvantage is the fact that after each foam dispensing process, the dispensing channel consists of the dispensed foam mass must be pulled out (sucking in air) to achieve a larger foam mass.

  • the required size of an air bellows can be adapted in a simple manner.
  • a plate valve has advantageously proven to be the second valve, preferably configured in the form of a ring, as a result of which a centric and swirled liquid outlet is ensured.
  • An annular sieve is provided as the foaming agent, which is penetrated in the middle by a holding finger, which means that this holding finger is able to hold a further sieve with a corresponding counter bearing if necessary.
  • a further development of the invention provides for the closure to be provided with a lever arranged at a right angle, as a result of which such a tilt closure is also suitable for upright dispensing of foam.
  • the locking lever is designed with a corresponding plug.
  • a particularly good closing ability and a particularly low actuating force of the closure is given in that the lever is designed as a ball rotary valve.
  • the mixing chamber By providing the mixing chamber with a plate-like liquid distribution body, a particularly uniform distribution of the liquid to be foamed is thereby achieved.
  • a liquid refill closure which is familiar to a person skilled in the art is provided, which is advantageously arranged on the bottom of the container.
