Apparatus For The Dispensing Of Liquids, Container Cartridge Suitable For This, And System Comprising The Apparatus For The Dispensing Of Liquids And The Container Cartridge

Abstract

The present invention relates to a propellant-gas-free apparatus for the dispensing of liquids, a container cartridge suitable for this for storing the liquid and the ensemble comprising both. The invention comprises a device for the exertion of pressure and for accommodating a container cartridge and a container cartridge in which the dispensing facility is integrated.

1 . A container cartridge, comprising:
 a base part;   a top part having a dispensing facility;   a stock cylinder for accommodating a drug, in dissolved or suspended form, extending from the dispensing facility to a bottom of the container cartridge; and   a container punch movable within the stock cylinder, sealing and not projecting outwards beyond the bottom of the container cartridge,   wherein the container cartridge is dimensionally stable, and manually not deformable.   
   
   
       2 . The container cartridge of  claim 1 , further comprising a sealing means, not indestructibly removable from the bottom of the container cartridge, for closing the stock cylinder. 
   
   
       3 . The container cartridge of  claim 1 , wherein the container punch is movable within the stock cylinder and does not project outwards beyond a rigid baseplate located at the bottom of the container cartridge. 
   
   
       4 . The container cartridge of  claim 1 , further comprising a sealing means closing off the dispensing facility. 
   
   
       5 . The container cartridge of  claim 1 , further comprising at least one holder for holding the dispensing facility in a top-side opening of the stock cylinder. 
   
   
       6 . The container cartridge of  claim 5 , wherein at least one of the dispensing facility and the holder are held in the top-side opening of the stock cylinder by at least one of glue, a weld, an ultrasonic weld, a crimp, and a screw cap. 
   
   
       7 . The container cartridge of  claim 1 , wherein the container punch is one of a piston (a container piston), and a ball (a container ball). 
   
   
       8 . The container cartridge of  claim 1 , wherein the stock cylinder has a filling capacity of at most 100 μl. 
   
   
       9 . The container cartridge of  claim 1 , wherein the stock cylinder has a filling capacity of at most 15 μl. 
   
   
       10 . The container cartridge of  claim 1 , wherein the dispensing facility is a nozzle having an opening. 
   
   
       11 . The container cartridge of  claim 1 , wherein the dispensing facility is a nozzle having at least two openings. 
   
   
       12 . The container cartridge of  claim 11 , further comprising channels leading to the at least two openings, the channels being oriented toward each other in a direction of the openings so that liquid jets or aerosol clouds dispensed from the openings collide with each other. means. 
   
   
       13 . The container cartridge of  claim 1 , wherein the dispensing facility includes filter means. 
   
   
       14 . The container cartridge of  claim 1 , wherein:
 the dispensing facility includes at least two parts, each with at least an essentially flat surface, and via which the two parts are connected to one another to form a unit,   at least one of the surfaces includes a microstructure with channels which form at least one liquid inlet into the unit and at least one liquid outlet from the unit.   
   
   
       15 . The container cartridge of  claim 14 , wherein at least one of the surfaces includes filter means. 
   
   
       16 . The container cartridge of  claim 14 , wherein at least one of the surfaces includes or one or more plenum chambers. 
   
   
       17 . The container cartridge of  claim 1 , wherein the container cartridge is not plastically deformable up to a pressure difference between an interior of the stock cylinder and external surroundings of at least 49 bar. 
   
   
       18 . The container cartridge of  claim 1 , further comprising:
 a head region;   a shoulder region; and   a belly region,   wherein a cross-section of the belly region, vertical to a longitudinal axis of the container cartridge is larger than a cross-section of the head region, vertical to the longitudinal axis.   
   
   
       19 . The container cartridge of  claim 1 , further comprising a baseplate having a largest cross-sectional dimension, vertical to a longitudinal axis of the container cartridge, than any other part of the container cartridge. 
   
   
       20 . The container cartridge of  claim 1 , wherein one part of the container cartridge has a cross-section, vertical to a longitudinal axis of the container cartridge, which is not rotationally-symmetrical.
