Definitions

  • the invention relates to a discharge device according to the preamble of claim 1. It should be particularly suitable for fine atomization of liquid, powdery or similar media, as well as for hand-held use and for one-handed operation.
  • the discharge device can have a propellant pump which delivers a propellant fluid and with which the medium is expelled from one or more media chambers or stores in the direction of one or more outlet openings by changing or reducing the volume of one or more pressure chambers.
  • the medium in the pressure chamber can be the same or of the same state of aggregation as the medium in the media chamber, these media expediently differ with regard to the state of aggregation, the propellant advantageously being a suitable gas, for example air, while the driven medium , namely, for example, a pharmaceutical or cosmetic active ingredient, is at least partially liquid and / or powdery.
  • the design is expediently provided in such a way that these media do not react chemically with one another, but can only form mixtures.
  • the volume of the propellant to be discharged per working stroke is expediently one to three potencies larger than the volume of the active ingredient to be discharged during this working stroke, the respective volume being able to correspond essentially to the total storage volume of the pressure chamber or the media chamber, which is almost completely emptied during the respective working stroke will.
  • DE-A-3 446 466 shows an inhaler with a media chamber from which the atomized medium is to be exhaled. Components lying inside the housing body of the media chamber serve to generate the mist.
  • WO-A-91/12 895 shows a discharge device in which internal components likewise do not extend as far as an end wall through which the outlet opening extends or limit associated transverse channels.
  • the invention has for its object to provide a discharge device of the type mentioned, in which disadvantages of known discharge devices are avoided and which make it possible, in particular, to discharge the smallest amounts of active substance with very simple construction.
  • At least one drive pump can be designed as a bellows pump, which is connected to at least one outlet opening with the interposition of at least part of at least one media chamber.
  • a propellant pumped by the propellant pump can not only lead to an effective emptying of the media chamber, but also to the fact that the active ingredient of the media chamber is finely distributed in a propellant stream before it is discharged and only then along with it along an outlet channel and through an outlet opening, e.g. Atomizer nozzle, is conveyed to the outside.
  • amounts of active ingredient of, for example, less than a tenth or a thirtieth of a cubic centimeter can be applied with a more than 100 times larger propellant volume of, for example, about 5 cm 3 .
  • the propellant pump so that its pressure chamber after a first emptying, e.g. Can be refilled via an inlet valve, but at least one pressure chamber of the propellant pump or the entire discharge device is advantageously designed only for single use or a single discharge process.
  • the respective pressure chamber can be completely closed in its initial state and, if necessary, be filled under tense pressure, so that, with small dimensions, a relatively large propellant volume is available which can be precisely determined in terms of its composition or degree of purity.
  • the propellant volume can advantageously be pressed out of the pressure chamber only by overcoming the resistance of a closure blocking the outlet of the pressure chamber, so that it is securely enclosed during the entire storage period of the discharge device and cannot escape gradually.
  • This closure can essentially be formed by the active medium itself if the media chamber forms a section of the outlet channel of the pressure chamber and the medium closes the media chamber essentially tightly or completely fills it as a tight packing.
  • a pressure-dependent for example, between the outlet of the pressure chamber and the inlet of the media chamber working or opening inlet valve required, but the inlet of the media chamber is always open to the pressure chamber of the propellant pump.
  • outlet-side end of the media chamber belonging to the outlet opening or a section of the outlet channel adjoining it can be closed with an optionally pressure-dependent working or opening closure, which secures both the pressure chamber and the media chamber against unintentional emptying and only opens when used as intended is.
  • a substantially dimensionally stable housing which has the outlet opening and / or the media chamber and which is expediently used with the propellant pump or with pressure handles turned away from one another for discharge actuation by at least one which is transverse and preferably transverse to its central axis or the central axis of the outlet opening this central axis is articulated and intersects at right angles.
  • the housing can be aligned in different angular positions with respect to the named components in order to simplify handling during discharge and / or to achieve a compact storage condition.
  • a pivoting movement is essentially only possible about a single defined hinge axis, which connects two limb sections of the discharge device which project freely therefrom and is transverse to the direction of actuation of the handles.
  • the propellant pump is expediently formed by an exposed, pillow-shaped bellows made of foils lying one on top of the other and tightly connected at the periphery of the pressure chamber in edge regions, at least the housing of which is at a distance adjacent to the outside of the pressure chamber can be partially enclosed so that the film parts make the only connection between the housing and the pressure chamber.
  • the two crowned and essentially the same size walls of the pressure chamber, which run out in a common connection plane, can directly and with their entire surface form the handles for actuating the discharge device and advantageously have a surface area of approximately the size of a ball of thumb, so that a Ergonomically very favorable handling for almost complete emptying of the pressure chamber under high pressure is guaranteed.
  • individual discharge devices can be connected non-destructively or by destroying the connection to a common carrier on which the individual discharge devices are expediently arranged in a single row or in a multi-row grid, one behind the other or next to one another, in which connection they are expediently such that that handling of adjacent discharge devices are not facing each other, but, like the hinge axes, lie approximately in the same orientation in a common plane.
  • the carrier or a separate component can also form a closure of the outlet opening at the same time, so that it is only released when the closure is removed by manual gripping and opening.
  • the discharge set 1 according to FIG. 1 has a large number of identical or different discharge devices 2, which can be removed independently of one another and can only be actuated in such a way that a media discharge takes place.
  • the discharge devices 2 can have the same or different sizes or fill volumes or fillers, depending on the type of application for which the set 1 is intended.
  • the discharge devices 2 lie in a straight row one behind the other, but could also be provided in a ring or ring or the like.
  • At least parts of adjacent discharge devices 2 can also be moved freely in the set 1, in particular transversely to their connecting straight line or their common plane, with adjacent discharge devices 2 not touching one another, but being completely spaced apart from one another via gap gaps and merely on a single side or end face are connected to a common support from which they protrude freely.

  • the handle 4 serves to hold and to actuate the discharge device 2 during use, the housing 3 then being freely movable with respect to the handle in its longitudinal direction but transversely thereto.
  • the housings 3 are not movable relative to one another, but the handles 4 of the discharge devices 2, so that they can be easily gripped for separation and brought into the most favorable position.
  • the discharge device 2 has a gas pump 5, essentially formed by the handle 4 or lying within it, in the form of a bellows pump which has no bellows.
  • the cushion-shaped pressure chamber 6 of the gas pump 5, which is approximately flat in all cross-sections, is formed by two opposing, spherically curved walls 7, 8 made of flexible or substantially inelastic film which, for example, does not exceed two under the loads occurring due to use. can be stretched five or ten percent.

  • the pressure chamber 6 thus has an original filling sealed tightly under excess pressure by the manufacturer, which resiliently secures the pliable handles 5, 16 and the neck 11 in their tensioned starting position, for example pneumatically, the gas pump 5 only permitting a single emptying of the pressure chamber 6 without subsequent refilling.
  • the housing 3 is formed only from two one-piece components, namely an outer housing body 17 and a housing core 18 lying essentially or completely therein, the housing 3 being directly connected to the handle 4 or the walls 7, 8 without the use of separate connecting members Pressure chamber 6 is connected.
