Definitions

  • the invention relates to a discharge device for media according to the preamble of patent claim 1.
  • Especially pharmaceutical and cosmetic, but also technical and similar media can consist of two or more components in the application state, which, due to a reaction time to be observed, a preparation that is as fresh and therefore effective as possible or because in the mixed state they tend to change, for example less durability , if possible, should be mixed shortly before or during use.
  • Such mixed media are therefore usually provided separately from each other in separate vessels. Either the components have to be mixed before use or, in the case of pharmaceutical and cosmetic preparations, occasionally applied one after the other and as a result to be connected or mixed. This requires some skill and also great care when it comes down to the fact that the components are to be used in an exact quantity ratio.
  • US-A-3 303 970 shows separate stores arranged on a support, from which, however, it is not conveyed by pumps, but only by opening outlet valves, since these are containers with a propellant gas filling.
  • the memories must already be connected to the carrier having an actuating mechanism during manufacture, since after the assembly of all the components of the discharge device, it is no longer possible to insert, remove or replace the respective memory.
  • the invention has for its object to provide a discharge device of the type mentioned, with which at least two components to be used in connection with each other can be applied precisely in time and brought into connection by simple manual operation without the media this must be subjected to pressure in the memory. Furthermore, the memories should be able to be attached or replaced independently of one another.
  • Each memory can be connected to the discharge device, removed from it or replaced at any time independently of the other, depending on the requirements placed on the discharge device.
  • the components, on the one hand, are kept separate from one another in their unused stored quantities and, on the other hand, the two components can be operated in a relatively precisely determinable quantity ratio by actuating only a single handle be brought into connection with each other or carried out.
  • Discharge pumps of the type mentioned can namely be designed as relatively precisely metering dosing pumps which deliver a precisely reproducible amount of medium with each pump cycle, the discharge pumps to be operated together having the same or different delivery rates depending on the requirements.
  • the discharge pumps in the manner of a register control, convey directly in succession, that is to say in stages, so that the associated components are discharged one after the other.
  • the design is provided such that when the handle is actuated, at least two discharge pumps which can be actuated by the latter deliver simultaneously or simultaneously, so that the components can be mixed with one another immediately during discharge.
  • the outlet channels of at least two discharge pumps expediently lead to a component mixing zone which is preferably in the immediate vicinity of at least one outlet opening.
  • the mixing zone is advantageously provided in the discharge direction in front of the outlet opening, in particular immediately adjacent to the inlet into an outlet nozzle, preferably both outlet channels in pass over a common end channel, which in turn is provided in the outlet nozzle, which is provided, for example, on the periphery and / or in the region of its rear end face with helical or spiral groove-like swirl channels flows.
  • the mixing zone is in the discharge direction after the outlet opening, in particular outside of the discharge device outdoors.
  • the emerging components may be applied separately at adjacent locations and then mixed with one another, for example by rubbing.
  • the components can be mixed very well before reaching the application point outside the discharge device, since hand-operated pumps are particularly advantageously suitable for producing a very fine spray jet when using appropriately designed outlet nozzles.
  • outlet openings are aligned with each other so that the jets emerging from them overlap not too far from the outlet nozzles, particularly when spray mist jets are generated due to the finest droplet distribution of the medium in this spray mist zone formed by overlapping, there is a very intensive mixing extremely short time interval to achieve before hitting the job site. This can be of particular advantage in the case of active pharmaceutical ingredients, since the more effective they are, the fresher they are mixed before use.
  • the discharge opening or the discharge openings are provided directly on the handle, being approximately flush in a wall of the handle or provided at the end of an extension projecting beyond the outer circumference of the handle, such as a beak could be.
  • the handle connects at least two discharge pumps lying next to one another, in particular in the manner of a bridge, and is preferably formed in one piece.
  • the handle lies in the area of the bridge, which forms a common bridge-like connection cap for the bottle-shaped storage device in particular, the handle preferably engaging with a wall edge in an annular web of the bridge corresponding to its basic shape, so that the two separate, bottle-shaped and possibly the same storage need not be in direct contact or mechanically fixed connection with each other, but can be arranged close to each other with a small gap.
  • the bridge or the connection cap as separate screw connections for the discharge pumps, optionally has separate connection caps for bottle necks of the approximately parallel immediately adjacent storage devices, the bridge or the connection cap also being formed in one piece can be.
  • Bottle necks of stores can also be brought into engagement with the connecting caps separately or simply by simple, pressure-tight snap connections, which is particularly advantageous if the associated stores are formed by a dimensionally stable component.
  • the separately designed stores are brought into engagement with the connection caps with their bottle necks by means of threads and screwed into the connection caps independently of one another.
  • an additional mounting bridge can be attached to the accumulators after the production of this connection, which is preferably narrow due to a flat, the accumulator in the bottom area enclosing plug cap is formed.
  • the design according to the invention is particularly suitable for discharge devices in which the discharge pumps are not designed as bellows, elastic chamber or similar pumps, but as thrust piston pumps, since these have significant advantages. They can be operated at high delivery pressures, are suitable for very precise dosing, allow an airtight seal for both the pump housing and the reservoir when the pump is in the initial position, ensure a high discharge rate and are suitable for both drop-wise and spray-jet-like applications or spray-like discharge suitable; Furthermore, they can be used both for liquid and for pasty or pulpy or similarly flowable media.
  • the respective discharge pump expediently has an outlet valve which is controlled by the pressure in the pump chamber or as a function of the piston position of the pump piston and which therefore only opens the connection from the pump chamber to the outlet channel when a suction valve which connects to the accumulator is in the closed state in the pump chamber relatively high pressure is built up.
  • a discharge device 1 has two vial-shaped, essentially cylindrical stores 2 for storing media components, in each of which a discharge pump 3 is inserted in the area of the bottle neck 4.
  • the two bottle necks 4 are positively connected to one another via a connection cap 5, which is round in plan view, in such a way that the two stores 2 are provided parallel to one another and at the same height at a short distance from one another.
  • the connection cap 5 forms on the inside a substantially axially symmetrical connection cap 6, which forms a common wall with the connection cap 5 in the area of the semicircular end and has the same height as the connection cap 5.
  • the connecting caps 6 overlap the two bottle necks 4 and are tightened via screw-threaded connections 8 on the bottle necks 4.
  • Each connecting cap 6 forms a holder 7 for the associated discharge pump 3 in the form of an annular shoulder receiving an annular flange of the pump housing, which clamps this annular flange 11 with the interposition of an annular seal 9 against the outer end face of the associated bottle neck 4.
  • Both discharge pumps 3 are connected to a common handle 10 in the form of an actuating cap which can be displaced axially parallel to the discharge pumps 3 and which has essentially the same basic shape as the connection cap 5, but is slightly smaller in plan view than this.
  • the handle 10 engages with its long round wall edge 13 facing the accumulators 2 into the inside of an annular web 12 surrounding it with a small gap distance, which extends over the outer end face of the end walls the connecting caps 6 forming end wall of the connecting cap 5 protrudes.
  • an outlet opening 16 is provided adjacent to the end wall to be pressed for actuation and is connected to the two pump chambers of both discharge pumps 3 via outlet channels 14 of the two discharge pumps 3 and to these adjoining outlet channels 15 in the handle 10 is.
  • the two discharge pumps 3 in turn are each connected to the associated storage unit 2 on the suction side near the floor by a suction channel 17 formed by a riser pipe.
  • the two axially aligned outlet channels 15 are directed towards one another up to the connection point to an end channel 18 or are formed by a single continuous channel to which the end channel 18 leading to the outlet opening 16 is connected at right angles; In the area of this connection, the arrangement of a swirl chamber possibly enlarged in cross section is conceivable.
  • the two outlet channels 15 are expediently of the same length, so that both components are exposed to approximately the same flow conditions.
  • 2 provided at the end of a freely protruding beak 19 is located on a long side of the handle 10 and in the middle of this long side.
  • Each discharge pump 3 is designed as a thrust piston pump, the cylinder housing 20 of which extends through the bottle neck 4 into the associated reservoir 2 and is reduced to the suction channel 17 several times in its outer diameter over its entire length at a distance from the inner circumference of the bottle neck 4.
  • the discharge pump 3 has a piston unit 21 which is displaceable in the cylinder housing 20 and has an elastic piston sleeve 22 which is formed in one piece with an elastically resilient compression sleeve 23 at its outer end.
  • the piston sleeve 22 and the compression sleeve 23 are arranged on the outer circumference of a piston tappet 24 which protrudes from the pump housing and over the ring web 12 into the handle 10 and is penetrated by the outlet channel 14.
  • the piston sleeve 22 forms in the transition area to the compression sleeve 23 the outer, annular valve closing part of an exhaust valve 25, not shown in detail, the valve seat of which is provided on the piston tappet 24.
  • the piston sleeve 22, including the valve closing part can be moved against the direction of the pump stroke with resilient compression of the compression sleeve 23 relative to the piston tappet 24, as a result of which the outlet valve 25 opens. This movement can either inevitably towards the end of the pump stroke by abutment of the piston sleeve 22 on an inner shoulder of the cylinder housing 20 or pressure-dependent by means of a corresponding overpressure in the pump chamber.
  • each discharge pump 3 has an inlet valve 26 in the form of a ball valve, which closes when there is excess pressure in the pump chamber, that is to say during the pumping stroke.
  • the handle 10 has on the inside of its end wall, which also contains the outlet channels 15, a number of protruding push-in sleeves 28 corresponding to the number of stores 2, which are axially secured by being connected to the outer ends of the piston tappets 24 such that all Cylinder cover caps 27 of the discharge pumps 3 are covered by the handle 10.
  • a mounting bridge 29 is provided in the form of a long round flat shell, which with its part-circular wall sections tightly encloses the accumulators 2 by plugging on and forms the base of the discharge device with its base plate.
  • the bracket bridge 29 forms a separate component, so that the memory 2 can first be attached to the connection cap 5, after which the bracket bridge 29 is attached.
  • a nozzle body 30 can be provided in the flow path of the media, which is on the circumference is provided with swirl grooves 31.
  • 30 spiral grooves 32 can also be provided on at least one end face of the nozzle body.
  • the media components to be mixed are either supplied separately or already brought together to the nozzle body 30, where they are swirled strongly and thereby intensively mixed, after which they emerge through the outlet opening 16, optionally as a spray jet.
  • a separate outlet opening 16a is provided for each component, the two outlet openings 16a being provided in the exemplary embodiment shown close to one another at the ends of beaks 19a projecting at an angle to one another.
  • the outlet channels 15a are not connected to one another within the discharge device 1a, but the media components meet only immediately after leaving the outlet openings 16a outside the discharge device 1a and in the immediate vicinity of the outlet openings 16a, so that they are then brought together and mixed here.
  • At least one or at least two discharge pumps can be changed in terms of their discharge quantity by adjustment, for example according to German patent application P 32 25 910.7, to which reference is made for further details. This allows the mixing ratio of the components to be adapted to requirements at any time.
