Definitions

  • the invention relates to an atomizer head according to the preamble of claim 1.
  • the object of the invention is to provide an atomizer head with which a particularly fine mist-like atomizing effect can be achieved, which can be mass-produced inexpensively, has a high level of functional reliability and is largely drip-proof.
  • the narrow annular gap upstream of the atomizer nozzle also has the further property that if the bottle is accidentally tipped over, the escape of liquid through the nozzle opening due to capillary action is prevented. In addition, the air must be displaced from this narrow annular gap. Before this is the case, the liquid inside the bottle has usually calmed down and is below the nozzle opening. For reasons of the air cushion which is inevitable for the atomizing function, the usually oval bottle is not filled with liquid up to half the contents of the bottle.
  • This "drip protection" of the bottle has the additional advantage that after cutting off the locking nipple before first use, the nozzle opening can remain open afterwards. This enables constant readiness for use without having to open a lid beforehand and then having to close it again after use.
  • the atomizer head 1 consisting of a single piece of plastic or metal, is placed on the bottle neck 12 of a squeezable, preferably oval, squeeze bottle made of flexible plastic.
  • the jacket of the atomizer head is designed as a truncated cone 3 at the front.
  • Inside the atomizer head 1 there is a flexible riser tube 4 made of plastic, which is closed on the jacket and has the same clear internal width over its entire length, i.e. the bore of the riser pipe 4 contains no constriction or lateral openings.
  • the riser pipe 4 is held in place by several, preferably three, wings 6 distributed around the circumference by friction. These wings 6 are supported on the inner wall 7 of the head and extend radially inwards.
  • annular bead 8 On the outside of the cylindrical bottle neck 2 there is an annular bead 8 which is wedge-like in cross-section, behind which an inwardly projecting annular rib 22 of the bore 23 of the atomizer head 1 snaps in elastically and thus after the atomizer head 1 has been placed on the bottle neck 12 is no longer detachable Connection results.
  • the ring rib 22 snaps elastically over the bead 8, so that then there is a connection that can no longer be broken without the use of force.
  • the riser pipe 4 is surrounded at the top by a sleeve 10, which extends inwards from the top plate 18.
  • the riser pipe 4 bears against at least one, preferably three, narrow stops 13, which are located in this intermediate space 12, so that a precisely predetermined height remains for the intermediate space 12.
  • a nozzle outlet opening 14 which has approximately the same diameter as the bore of the riser pipe 4.
  • the nozzle outlet opening 14 is closed on the outside by a nipple 15, which is separated before the first use. After this nipple 15 has been cut off, the nozzle outlet opening 14 is in constant communication with the ambient air.
  • the transition between the head plate 18 and the nozzle outlet opening 14 is formed by a sharp edge, which promotes the formation of air turbulence and thus the atomization effect.
  • the width b of the annular gap 11 is smaller than the distance a between the end face 5 of the riser pipe 4 and the opposite inner wall of the head plate 18.
  • the diameter of the nozzle outlet opening can be between 0.6-1 mm, preferably approximately, depending on the desired application rate and other criteria 0.8 mm.
  • the width b can be, for example, approximately 0.3 mm and the height a approximately 0.6 mm.
  • FIG. 3 shows a squeeze bottle 24 with the atomizer head 1 attached.
  • the riser pipe 4 extends into the bottle interior and ends close to the bottom 20 of the bottle.
  • the central axis y of the atomizer head 1 is inclined with respect to the longitudinal central axis x of the bottle 24. It is thereby achieved that a spray mist directed away from the user and directed upwards can be generated.
  • this atomizing nozzle When a hand is pressed onto an upright squeeze bottle 24 filled with low-viscosity liquid to almost half, it creates an overpressure inside the bottle. On the one hand, this acts on the liquid level inside the bottle and drives liquid upwards inside the riser tube 4 immersed in the liquid. On the other hand, air is pressed out of the interior of the bottle 24 through the annular gap 11. Since this annular gap 11 is relatively narrow is formed, the air in this annular gap 11 is greatly accelerated. As a result of this relatively high air speed, liquid is entrained from the riser 4 by the injector action and atomized as a result of eddy formation in the region of the nozzle outlet opening 14.
  • the cross-sectional area of the annular gap 11 is at most 1.8 times and at least 1.2 times the cross-sectional area of the air passage of the intermediate space 12 in front of the nozzle outlet opening 14.
  • the atomizer head is insensitive to manufacturing tolerances of both the atomizer head 1 and the riser pipe 4 and against any incomplete insertion of the riser pipe 4 up to the stops 13 or loosening of the riser pipe during use.
  • a riser pipe 4 that does not extend all the way to the stops 13 only results in a weaker degree of atomization, but not a complete failure of the atomizing effect, as is often the case with nozzles according to the prior art.
  • the atomizer head is largely drip-proof, since the air cannot escape suddenly from the narrow annular gap 11 and also the afterflow the liquid is also slowed down due to capillary action. After the liquid has calmed down, it flows back into the bottle from the area of the nozzle. This makes it possible to do without a cover or screw cap even after the nipple 15 has been disconnected. With such a bottle, this enables constant readiness for use.
  • the bottle is therefore without any preparatory action - such as opening a closure, unscrewing a lid or the like. Ready for use so that a liquid mixed with an active ingredient - e.g. deodorant - can be finely sprayed by pressing on the bottle wall.
