Definitions

  • the invention relates to a metering dispenser according to the preamble of claim 1.
  • a dispenser is from the EP 0 753 353 A2 respectively.
  • Dosing dispensers are also known from the prior art, in which the mixing ratio of two components is infinitely adjustable.
  • a dispenser can be used, for example, as a lip product dispenser to mix two components with different shades, so that the color can be adjusted continuously in a wide range.
  • the dimensions of dispensers for these products are extremely small, so they require a very compact design of all components, especially the pump unit.
  • the dosage amount is extremely small in these products compared to the prior art.
  • these products are highly viscous and thus require a pump with a small dead volume and relative to the dosing volume wide-opening valves. In order to achieve an exact dosage for these requirements, the valves should also close exactly and automatically, in order to avoid product backflow.
  • low-cost production must be enabled by using fewer parts and easy assembly.
  • the dosing dispenser has two pumping units, each associated with a replaceable cartridge, in which, for example, each one suntan type is included with very different sun protection factors.
  • This also applies to the solution according to the WO 03/092905 , in which two pump units are recessed on the upper side of each cartridge and also held by cylindrical recesses in the housing.
  • the pump units or their pumping pistons are actuated via an actuating element which is in connection with a pump or nozzle head, which is mounted in a housing of the dosing dispenser and is actuated by the consumer via a handle.
  • These known dosing dispensers have basically proven themselves in practice; however, they still suffer from disadvantages.
  • the pumping units and their storage at the cartridge outlet have a comparatively complicated construction.
  • the invention has for its object to provide a dosing dispenser having at least one structurally simpler and more reliable pump unit.
  • the solution according to the invention has a particularly simple and stable construction in comparison to the dispensers described above, since the pump unit is guided in the upper region of the cartridge or of the container in a sleeve. Through this sleeve in continuation of the cartridge, each component to be metered can be easily passed through the inlet and outlet valve of the pump unit. In addition, by this arrangement, the leadership of the pump piston or the storage of the pump cylinder can be made very stable and the number of movable components can be reduced.
  • the pump unit is made as an injection molded part.
  • the pump piston or pump cylinder of the respective pump unit with the sleeve on the container are particularly easy to assemble and offers a stable design with low overall height.
  • Advantageous developments of the invention are the subject of the other dependent claims.
  • the sleeve is preferably integrally formed on the container, in particular in injection molding.
  • the sleeve may have in its interior ring beads or undercuts for locking with the pump cylinder and / or the pump piston.
  • the pump cylinder is securely anchored or pressed into the sleeve, so that the pump cylinder with its bottom an inlet valve, especially in the form of a membrane can securely fix or pinch.
  • the spring for the outlet valve which is arranged on a folding spring clip, which is preferably injection-molded integrally with the pump piston.
  • the spring clip a film hinge and this opposite have a locking pin, so that there is a simple, inexpensive production and assembly.
  • the spring may also be made of plastic and integrally formed in a meandering shape on the spring clip, so that a particularly simple structure is achieved.
  • Fig. 1 Based on the perspective view in Fig. 1 Let us first describe the basic concept of the metering dispenser pump, which generally consists of a container 1, in particular in an oval or semicircular cartridge shape, and a pumping unit 2. In this case, two or more such containers 1 may be provided with each associated pump unit in a metering dispenser. In an advantageous manner, the adjustment of the mixture of the individual components in the containers 1 can take place by turning an adjusting element (not shown). In many applications, however, the fixed setting of the mixing ratio is sufficient.
  • the output of the component from the respective container 1 takes place here by pressure of the pump piston 3 of the pump unit 2 via an actuating element B, as is indicated only schematically here.
  • the pump piston 3 acts together with a pump cylinder 6, as shown in the sectional views of Fig.
  • a so-called pressure-suction pump pump unit 2 is used according to the innovation in a sleeve 7, which continues the container 1 in the upper region.
  • the sleeve 7 is injection molded together with the container 1, so that there is a stable, integral design.
  • a coil spring for returning the pump piston 3 is also inserted in a simple manner.
  • the preferably formed of elastic plastic pump cylinder 6 is fixed in the sleeve 7 in a sealing manner or pressed, wherein the pump cylinder 6 with its bottom and the inlet valve 4 ', in particular in the form of a membrane, clamped (see. Fig. 3 , right perspective view).
  • Fig. 2 the pump piston 3 is shown in side view, sectional view and perspective view.
  • the structure of the exhaust valve 4 associated spring 5 can be seen, which is arranged on a spring clip 5a, which preferably integrally with the pump piston 3 injection molded.
  • a film hinge 5b may be formed on the spring clip 5a in order to fold it over and lock it with an opposing catch pin 5c in the wall of the pump piston 3.
  • the plastic spring 5 is preferably formed in a meandering shape on the spring clip 5a or injection molded, so that there is a bias and the spring 5 goes on actuation of the pump unit 2 to block.
  • Fig. 3 the pump cylinder 6 is shown in perspective view from above and from below. As can be seen, this has a pump space 4a and on the outer circumference a design in the manner of a sleeve seal to safely seal the pump unit 2 against the sleeve 7 and the container 1, in particular during the operation of the pump piston 3, which then into the pump chamber 4a dips. It goes without saying that the component conveyed from the container 1 in this case can be forwarded to a mixing nozzle (not shown). As indicated above, a plurality of such containers 1 with respective pumping unit 2 can be provided in the metering dispenser, so that by centering an actuating element, the pumping units 2 each deliver 50% of the total output quantity with identical stroke or delivery volume.
  • the mixture then contains equal parts of the two (or more) components from both containers 1.
  • appropriate spacers of the control element and appropriate intermediate ratios between the delivery volumes can be selected 6, so that each component is continuously variable between 0% to 100%.
  • the containers 1 can also be bottle-like or in the manner of a bag and have different cross-sectional shapes.
  • the container 1 in particular in the form of an oval cartridge as in Fig. 1 shown for different substances, eg. B. cosmetics.
  • This pump unit can of course be used as a single pump or non-adjustable two-component dispenser for high-viscosity products with low dosage such.
  • As shaving gel two-component silicone (adhesive gel) or adhesive.
