Definitions

  • the invention relates to a device for atomizing a cosmetic, medical or the like liquid according to the preamble of claim 1.
  • Such devices are generally known and are used primarily for atomizing perfume, eau de toilette, or the like.
  • the known devices are characterized in that the atomizer cap is attached to the free or outer end of the dispensing tube protruding from the pump body in such a way that it as a whole with the dispensing tube is moved.
  • the pump stroke of the dispensing tube and the attached atomizer cap is approximately 7 mm to 8 mm.
  • a push button spray device with a spray body which has a cylindrical chamber in which a piston is slidably guided, one end of which protrudes liquid-tight through an opening in the chamber and is acted upon by a push button. Furthermore, the push button spray device has a nozzle connected to the chamber for spraying the liquid.
  • a pivoting lever Arranged between a pushbutton and the piston end is a pivoting lever which transfers the pushbutton's pushing path to the piston and pushes it against the action of a spring into the chamber, the pivot point of which lies beyond the central axis of the piston. Guide elements are also provided for the print path of the push button.
  • the aforementioned device consists of many individual parts and thus has the disadvantage of high manufacturing costs and considerable assembly effort during assembly.
  • the piston serves at least partially for axial guidance, so that there is an increased risk of leakage when there is a frequent force acting perpendicular to the axial guidance of the piston.
  • a trigger spray device which can be attached to a bottle or the like is known, which essentially consists of a U-shaped body, which at one end of a leg with a cap which connects to the bottle and has a pump is connected and opens into an operating lever at the other end of the other leg.
  • the U-shaped body bends on an elastic element connecting the two legs, and a dispensing arm which is pivotably guided in a channel of the upper leg moves downwards together with a dispensing tube protruding from the pump, so that liquid is conveyed and sprayed becomes.
  • the disadvantage here is that the dispensing tube must take over the axial guidance, so that forces occurring perpendicular to the axial direction of the tube also create a risk of leakage, at least when operated for a longer period, so that the entire device can become leaky or even inoperable.
  • the present invention has for its object to provide a device for atomizing a cosmetic or the like liquid based on the prior art mentioned, which is permanently leak-proof and functionally safe and in particular a lateral load on the discharge valve associated with the pump when actuating the Pump is avoided.
  • the atomizer cap is firmly mounted on the container.
  • the dispensing tube and thus the pump are actuated by a separate actuating member which is pivotally mounted in the atomizer cap and which ensures that the dispensing tube is axially loaded in a predetermined manner.
  • accidental transverse loading is reliably avoided by means of the axial support and guidance of the discharge channel. Accordingly, there is no longer an increased risk of leakage between the delivery tube and the pump body in the device according to the invention.
  • the function of the pump can also no longer be impaired by lateral loading of the dispensing tube.
  • the actuator is preferably connected in one piece to the discharge channel, at the free end of which the atomizing nozzle is arranged.
  • the discharge channel and the actuating member accordingly form a unitary unit which is placed inside the atomizer cap, in a predetermined assignment to the delivery tube of the pump.
  • the lever of the actuating member is increased relative to the axially movable dispensing tube, with the result that it can be moved into the pump body or container with less effort, with appropriate atomization of the liquid pressed out of the pump chamber.
  • this measure enables finer metering of the liquid emerging from the atomizer nozzle.
  • the features of claim 11 provide an advantageous connection between the actuator on the one hand and Discharge channel including atomizer nozzle on the other hand, which on the one hand is easy to manufacture and on the other hand extremely flexible and reliable.
  • Liquid from a container 1 comprises an atomizer cap 7, which is mounted on the free or outer end of a dispensing tube 6, which as an active part of a a container opening 2 mounted pump 3 against the action of an elastic element arranged within the pump body 4, namely a helical compression spring 5 is axially movable into the pump body 4.
  • the atomizer cap 7 is at the outer end of the said delivery tube 6 mounted in such a way that the fluid channel 8 of the dispensing tube 6 opens into a discharge channel 9 which extends approximately transversely thereto and is formed within the atomizer cap 7 and at the free end of which an atomizer nozzle 10 is arranged.
  • the atomizer cap 7 is fixedly mounted on the container 1, namely on the upper container edge 30, with a clamped fixation on the upper container edge 30.
  • the atomizer cap 7 comprises an actuating member 11, which is connected in one piece to the discharge channel 9, in such a way that when the actuating member 11 is actuated, the dispensing tube 6 can be moved into the pump body 4 with corresponding entrainment of the discharge channel 9 (arrow 31 in FIG. 4) .
  • the aforementioned discharge channel 9 is supported and guided axially movably on the inside 12 of the atomizer cap 7 facing the atomizer nozzle 10 on the one hand and on an inside on the atomizer cap 7 approximately above the dispensing tube 6, namely, integrally formed projection 13.
  • the latter projection 13 is formed by two axial ribs arranged diametrically to the central axis 15 of the dispensing tube 6, which are encompassed on the sides facing the atomizer nozzle by a web 16 which is formed on the discharge channel 9 and is approximately U-shaped in cross section, forming an axial guide.
  • two axially extending side guide ribs 17 are arranged at a distance from one another, namely integrally formed, between which the end of the discharge channel on the atomizer nozzle side is axially displaceably guided.
  • the atomizer cap 7 has a preferably axially extending opening 14 in the region of the atomizer nozzle 10 such that the atomizer nozzle 10 is in any possible axial position relative to the permanently attached atomizer cap 7, which is brought about by the actuating member 11 or is freely accessible relative to the container 1 or container liquid can escape through the atomizing nozzle in any axial position.
  • Said side guide ribs 17 are preferably arranged on both sides of the through opening 14 in the atomizer cap 7.
  • the actuating member 11 is articulated in the area below the atomizer nozzle 10 on the inside 12 of the atomizer cap 7.
  • the actuating member 11, starting from an actuating button 18 which is formed diametrically to the atomizing nozzle 10, has two spaced-apart side cheeks 19, the ends 20 of which are inserted into complementary receptacles 21 to form a hinge-like articulated connection from below or on the container side, said ends 20 of the side cheeks 19 being held in these receptacles 21 by the helical compression spring 5 which is arranged inside the pump body 4 and which dispenses the delivery tube 6 and accordingly the discharge channel 9 together with the actuating member 11 from the pump body 4.
  • the side cheeks 19 extend according to FIG. 5 to both sides of the discharge channel 9, approximately parallel to it, the distance between the side cheeks 19 and the central axis of the discharge channel 9 each being somewhat larger than the distance between said central axis and the axially extending guide ribs 13 on the underside of the atomizer cap 7.
  • the receptacles 21 for the atomizer nozzle-side ends 20 of the side cheeks 19 assigned to the actuating member 11 are on the lower or the container 1 facing sides of two approximately at a distance from the said side cheeks 19 extending support strips 23 formed on the inside 12 of the atomizer cap 7, in the form of recesses.
  • each laterally extending pins 24 can be hooked on the atomizer nozzle-side ends 20 of the side cheeks 19 to form the hinge-like articulation.
  • the recesses 21 are replaced by C-shaped or U-shaped receiving openings.
  • the central axis 15 of the dispensing tube 6 and thus the pump 3 is offset from the area of the central container axis 25 in the direction of the atomizing nozzle 10.
  • the effective lever arm between the dispensing tube 6 and the actuating button 18 is thus enlarged, as a result of which a finer dosage is possible with less effort.
  • connection between the actuating member 11 and the discharge channel 9 is formed by a flexible connecting tab 26 which, starting from the end of the discharge channel 9 on the dispensing tube side, slopes obliquely downwards or towards the container 1 towards an inside of the actuating member 11, namely in the region of the end of the atomizer nozzle
  • Operating button 18 integrally formed reinforcing rib 27 extends.
  • the connection of the connecting strap 26 to the reinforcing rib 27 takes place in the lower region thereof, as clearly shown in FIGS. 1, 3 and 4.
  • the reinforcing rib 27 extends in the area below the actuation button 18 in a plane which is defined by the two central axes 15 and 25 of the dispensing tube 6 and the container 1 (see FIG. 5). 5, the two support strips 23 are each formed on the two outer sides of the side cheeks 19.
  • the container 1 with the atomizer cap 7 represents an approximately cuboid object. It is equally conceivable that the container together Design the atomizer cap in cross section or in plan view in a circular cylindrical or oval shape.
  • the pump 3 is a conventional pump, a detailed description thereof is omitted here.
  • the arrangement of a riser tube 28 at the end of the pump body on the inside of the container is also known. The same applies to the attachment of the pump body 4 to the edge of the container opening by means of a crimped sheet metal ring 34.
  • the meaning of the described device lies in the integral design of the discharge channel and the actuating member and their arrangement within an atomizer cap in exact association with the dispensing tube, which is the active pump actuating element.
  • the arrangement and design of the actuator 11 is such that a maximum lever arm is effective on the dispensing tube, with the result that an exact dosage is possible with little finger pressure. A more uniform atomization can also be achieved in this way.
