Definitions
- the invention relates to a dispenser for metered dispensing of liquid media according to the preamble of claim 1.
- a device for metered dispensing liquid filling contents from containers is known.
- Volumetric devices for dispensing metered quantities of liquid filling contents are known, for example, in the form of so-called drop dispensers, which have found some use in the medical and cosmetics sectors.
- the delivery takes place by tilting the container. For exact metering and operating convenience, it is provided that the contents of the filling always first pass into a flood chamber upstream of the discharge while the container is tilted.
- the operator releases the filling contents from there via a metering piston shifted in the slide, so that the output is no longer influenced in an uncontrolled manner by the pressure of a residual filling, as is the case with squeeze bottles.
- the metering piston has axially spaced piston discs on, wherein the distance corresponds to the length of the flood chamber. In the closed position, the container-side piston disc is spaced from the container-side flood chamber opening. The flood chamber itself can then release larger metered, always equal amounts as a volumetric discharge device. With the corresponding forward displacement of the slide, the container-side piston disc separates the portion intended for dispensing from the remainder of the filling contents.
- the output side piston disc stands just before the output side flood chamber opening. A further shift then lets the metered amount escape.
- the flood chamber is formed by a cylindrical shaft, through the ceiling of the piston rod guided projects.
- Low-priced conditions exist when the slide has a slide button for displacing the metering piston. This leads to a comfortable one-hand operation.
- the disadvantage is that the dosing accuracy is not sufficiently good for a head-mounted application using gravity.
- the object of the invention is therefore to provide a dispenser with a fillable by gravity dosing, the dosing and handling is improved.
- a dispenser which has the significant advantage over simple squeeze bottles, that a precise amount is discharged by a dimensional interpretation of the filling volume of a metering chamber together with the lifting movement.
- a metering chamber in the metering piston in the form of a volumetrically determined cylinder section thereof, a position of the metering chamber in the flood chamber is achieved, which enables the dispenser not only to discharge the upside down medium, but also to discharge medium in a strongly extended angular range, thereby almost completely emptying the container.
- the dispenser can get along with significantly fewer parts and thus be produced inexpensively.
- the discharged dose can be carried out in the form of drops or as a soft spray.
- the system can be designed with or without nozzle closure.
- the metering chamber is also preferably associated with the discharge side an automatically closing valve. As a result, a return flow into the metering chamber is avoided.
- the flood chamber has a lid-like container cover, which has individual discrete passage openings for a passage of medium from the container into the flood chamber.
- a backflow of medium from the medium flowed into the flood chamber into the container is thereby hindered, which may likewise have an advantageous effect on the extended angular range of the application of the dispenser.
- FIG. 1 shows longitudinal sections or longitudinal partial sections of a dispenser in a sequence of functions A, B, C, D,
- FIG. 2 shows longitudinal partial sections of the dispenser according to FIG. 1 in a sequence of functions E, F
- FIG. 3 shows longitudinal sections or longitudinal partial sections of the dispenser according to FIG. 1 in a sequence of functions G to K.
- FIGS. 1 to 3 show a dispenser 1 with a dosing chamber 2, which can be filled by gravity, for metered dispensing of liquid media.
- the dispenser 1 comprises a container 3 for receiving a liquid medium 4.
- a hand-operated pump 5 is arranged on the container 3.
- the manually operable pump 5 comprises a flood chamber 6, into which liquid medium 4 flows when the container 3 is turned over, for which purpose the flood chamber 6 is fluidically connected on the inlet side to an outlet opening 7 of the container 3.
- metering piston 8 In the flood chamber 6 a displaceable by an actuating stroke F metering piston 8 is arranged, which discharges metered medium. Through the metering piston 8, a media channel 9 extends, which is expanded on the inlet side as a volumetrically determined cylinder portion 10. In the cylinder portion 10 engages a projecting into the flood chamber 6 plunger 11 as a pressure piston todesign administratn introduced in the cylinder portion 10 of the metering piston 8 under gravity or filled medium.
- the flood chamber 6 is associated with the discharge side an automatic outlet valve 12 which is fluidically connected to a discharge opening 13 having a discharge head 14.
- the discharge head 14 preferably receives an automatically closing spring-loaded valve body 15.
- a suitable discharge head is described for example in WO 2009/149825 A1.
- the dosing piston 8 preferably has an enlarged inlet connection 16 on the side facing the plunger 11.
- the volumetrically determined cylinder section 10 preferably forms a partial section of a pot-shaped metering piston 8.
- the volumetrically determined cylinder section 10 forms a metering chamber in the metering piston 8.
- the plunger 11 preferably protrudes from a lid-like container cover 17.
- the container cover 17 has individual passage openings 18 which serve for the admission of medium 4 from the container 3 into the flood chamber 6 under gravity when the container 3 is turned over.
- the container cover 17 forms a bottom of the flood chamber 6 provided with passage openings 18.
- the container cover 17 furthermore preferably has a sleeve-like extension 19 as an edge-side boundary of the flood chamber 6. At this extension 19 of the metering piston 8 is guided internally sealed.
- the sleeve-like extension 19 is preferably arranged coaxially to the plunger 11.
- the dispensing head 14 has, for example, an inner sleeve 20, through which a media channel 21 is guided, which is fluidically connected to the cylinder portion 10 in the metering piston 8 and the discharge opening 13.
- a compression spring 22 Against the action of a compression spring 22, the discharge head 14 together with the metering piston 8 to the plunger 11 zubewegbar, ie the metering piston 8 performs a relative movement with respect to a pump base part 23 fixed to the container 3.
- the pump 5 is arranged on the container 3.
- the compression spring 22 is supported between this pump base part 23 and the discharge head 14, which are mutually displaceable to perform a pump stroke, as the force arrow F in the figure D of FIG. 1 shows.
- the discharge head 14 may have at least one actuating surface 24 for its actuation.
- the figure A shows the dispenser 1 in half section in the storage or rest position.
- the dosing chamber forming cylinder portion 10 in the metering piston 8 is emptied by gravity.
- In the flood chamber 6 reached medium flows through the passage openings 18 back into the container.
- Figure B shows the dispenser 1 in an application position.
- the application position can be an upside down position or an angled position, as shown in Figure B.
- the dispenser 1 can be reliably operated with angular deviations of up to 45 ° from the vertical.
- the figure C shows that the cylinder portion 10 is open at the top.
- the valve 12 below the cylinder portion 10 closes the dispenser 1 downwards, i. through the discharge opening 13 no medium escapes.
- the discharge head 14 is displaced along the symmetry axis in the direction of the plunger 11 by pressure on the actuation surfaces 24 (arrows indicated by F).
- the compression process is initiated.
- dosing 25, which may be provided in the wall of the cylinder portion 10, the chamber thus formed, however, is not yet sealed.
- Medium is pushed back into the flood chamber 6 and the container 3.
- Fig. 2 shows with the figures E and F, the discharge of a quantity of medium, here a drop.
- the illustration E shows that at the end of the metering slots 25, the plunger 11 seals in the cylinder section 10 of the metering piston 8, ie a volumetric quantity of medium is then separated from the flood chamber 6.
- Another movement in the direction of force F leads to an increase in pressure within the cylinder portion 10 of the metering piston 8. Due to the pressure increase opens the valve 12, so that medium is displaced by the valve 12 in the direction of discharge opening 13 through the media channel 21.
- the droplet formation begins by the pushed-medium.
- the figure F shows that at the end of the actuation path, the valve 12 closes again, since no medium is nachgeschoben.
- the drop formed at the discharge opening 13 breaks off and falls by gravity in the direction of the application target area, for example the eye.
- Fig. 3 shows with the figures G to K, the provision of the dispenser 1 in its initial position.
- the illustration G illustrates that when the force on the actuating surfaces 24 decreases, the discharge head 14 moves back to its original position, wherein within the cylinder portion 10 of the metering 8, a negative pressure.
- the illustration H illustrates that, as soon as the metering slots 25 are again run over by the plunger 11 in the opposite direction, the negative pressure within the cylinder section 10 ensures a sudden refilling of the cylinder section 10 in the metering piston 8. If no metering slots 25 are provided, this is the case when the plunger 11 is disengaged from the metering piston 8.
- Figure I shows the pump 5, which has reached its starting position again and is ready to deliver a next drop.
- a next Ruleaustrag begins again with the action of an actuating force F, as shown in Figure D.
- Figure J shows the dispenser in application position.
- the figure K shows the dispenser 1 in half-section in the storage or rest position.
