Definitions

  • the invention relates to a dispenser head for a foam aerosol according to the preamble of claim 1.
  • Foam aerosols are used, for example, in the household for cleaning carpets, tubs or the like, or also in the field of cosmetics for hair and body care. It is known to drive out the active substances for such aerosol foams with hydrocarbons and fluorinated chlorinated hydrocarbons. Fluorinated chlorinated hydrocarbons are increasingly rejected for environmental reasons. Hydrocarbons are flammable and therefore not harmless.
  • Compressible gases such as nitrogen or compressed air can be considered as safe blowing agents. While hydrocarbons dissolve in liquid active substances, this is not the case with nitrogen or compressed air. It is therefore difficult to use the pressure with such propellants Keep consumption of the active ingredients at a sufficient level in order to obtain an effective spray. Moreover, it is difficult with such pressure media to obtain desired aerosol foams in conventional valve-dispenser head combinations.
  • a dispenser head of the type mentioned at the outset has become known, which can be placed as a one-piece component on a package containing an active substance solution, the component having a throttle opening of relatively small cross-section at the front end of a flow channel.
  • the component In the wall of the flow channel behind the throttle opening there is at least one opening connected to the atmosphere, the cross section of which is significantly larger than that of the throttle opening.
  • a fine-meshed grid or sieve is arranged at the rear end of the channel.
  • the invention has for its object to provide a dispenser head for a foam aerosol, with which liquid-insoluble propellant gases are effectively produced while maintaining sufficient propellant pressure at the end of the delivery of the active substance.
  • an inner channel section for receiving a tappet of a valve of a package containing a non-soluble gaseous propellant, the channel section having a throttle opening.
  • the channel section is connected via a plurality of webs which are arranged at a distance in the circumferential direction to the interior of a hat-shaped or cap-shaped section which surrounds the channel section at a distance and to which the tubular flow channel is molded.
  • the opening is formed between the webs and the cap-shaped section is sufficiently spaced from the side of the cap.
  • the design of the one-piece head in which the openings through which air is sucked in ejector-shaped are moved into the interior of the head, so that there is no impairment due to contamination or the like.
  • the openings formed by the webs are placed very close to the throttle opening, so that intensive swirling can take place to form an effective and fine foam with the aid of the sieve at the end of the tubular channel.
  • a conical is at the transition of the cap-shaped section to the flow channel tapered passage is provided, and the webs are connected to the conical wall. In this way, the ejector effect comes about satisfactorily.
  • webs are preferably provided. According to another embodiment of the invention, they are formed on the outside of the channel section and gradually widen in the direction of the cap-shaped section.
  • a throttle opening with a relatively small cross-section follows in the flow path behind the conventional valve for the aerosol pack.
  • the cross section can have 0.2 to 1.5 mm, preferably approximately 0.6 mm. These diameters depend to a large extent on the nature of the substance to be foamed. As a result, the liquid active substance flows through the throttle opening at a relatively high speed and tears outside air from the lateral opening in the wall of the flow channel, which leads to the swirling and foaming of the active substance.
  • the swirled and air-enriched jet can meet a sieve which is arranged at the end of the channel, as a result of which a compact foam or a surface foam emerges, depending on the distance to the object to be sprayed.
  • the sieve can preferably have a mesh size of less than 0.2 mm.
  • the sieve can be molded into a ring made of plastic, which is then inserted into a recess at the upper end of the channel section.
  • the one-piece production of a sieve with A plastic ring or the like in the injection molding process is easily possible with conventional techniques.
  • a sieve or the like can be attached to the end of a sleeve, which can then be fitted like a hat onto a hollow cylindrical pin which delimits the lower part of the flow channel and has the opening (s).
  • the dispenser head 50 according to FIG. 1 is designed as a one-piece component 52 and is made of plastic material. It has a lower hat-shaped or cap-shaped section 54 and an upper sleeve-shaped or tubular section 56.
  • section 54 there is a hollow cylindrical extension 58 which interacts with a valve (not shown) of an aerosol pack onto which the dispenser head 50 is placed.
  • lug 58 may interact with the tappet of an aerosol valve.
  • the transition from the interior of the cap-shaped section 54 to the channel 60 of the tubular section 56 is conical, as shown at 62.
  • On the wall of the conical section 62 are four webs 64 arranged at the same distance, two of which can be seen.
  • the webs 64 extend down to the outer wall of the tubular extension 58, whereby it is attached to the tubular section 56.
  • the webs form openings 66 between them, through which air can flow along arrows 68.
  • the tubular extension 58 is closed at the upper end by a wall 70 in which a throttle opening 72 is provided, for example with a diameter of 0.6 mm.
  • the dispenser head 50 is used to dispense aerosol foams, such as those used for cleaning carpets and tubs or in the cosmetics sector.
  • the corresponding active ingredient (a surfactant solution) is filled in a conventional aerosol pack and is under the pressure of a water-insoluble propellant, such as air or nitrogen. If the aerosol valve is opened by finger actuation of the dispenser head 50, active substance flows through the throttle opening 72 under pressure, air is thereby entrained within the cap-shaped section 54 and also flows into the channel 60.
  • an annular recess can be formed 29 can be provided which receives a plastic ring 30 which is formed together with a fine-meshed sieve 32.
  • the sieve has a mesh size of preferably 0.2 mm or less and is made of plastic or metal.
  • a pair of opposite wings 76 can be seen, the upper side of which also has a cross section triangular grooves that lie on a circular arc is provided.
  • the wings 76 serve to grasp the dispenser head 50, for example with the index and middle fingers, in order to press the dispenser head 50 against the packaging and to actuate the aerosol valve (not shown).
