Patent number: 7963955Abstract: Foil bags are used as a primary packaging for liquids, the bags permitting the liquid to be taken therefrom without the application of a considerable amount of force. A container is provided for a medicinal liquid, the container being gas-tight and liquid-tight so that it is storable over many months. The container includes a collapsible foil bag on which a flange, which is stable in respect of shape, is disposed. The flange is designed for fitting onto a discharge connection member. The container can be disposed in a casing which is stable in respect of shape. The medicinal liquid does not come into contact with air and is protected from the effect of light. The medicinal liquid may be dispensed from the foil bag in many partial quantities over a prolonged period of time, with a respective partial amount thereof being converted into an aerosol by means of an atomizer.Type: GrantFiled: January 12, 2004Date of Patent: June 21, 2011Assignee: Boehringer Ingelheim International GmbHInventors: Bernhard Freund, Dieter Hochrainer, Heinrich Kladders, Bernd Zierenberg, Joachim Eicher, Johannes Geser, Martin Essing, Holger Reinecke

Patent number: 7645383Abstract: A microstructured filter is presented having an inlet for unfiltered fluid; an outlet for filtered fluid; a plurality of projections, which form at least one row in a mutually juxtaposed relationship across the filter, that project out of a base plate and are an integral component of the base plate; a plurality of passages between the projections; and a cover plate which is securable to the base plate to cover the projections and the passages. The passages form a plurality of through paths from the inlet to the outlet. The inlet includes an elongate inlet slot for the unfiltered fluid that extends over approximately the entire filter width and is approximately as high as the projection on the outlet side of the filter.Type: GrantFiled: October 14, 2005Date of Patent: January 12, 2010Assignee: Boehringer Ingelheim International GmbHInventors: Klaus Kadel, Johannes Geser, Joachim Eicher, Bernhard Freund, Stephen Terence Dunne, Wulf Bachtler

Patent number: 7246615Abstract: A nozzle assembly for use in atomizing and generating sprays from a fluid. The nozzle assembly includes two members, each with generally planar surfaces, that are joined together. A first set of channels is formed in the generally planar surface of a first one of the members to form, in cooperation with the generally planar surface of the second of the members, a plurality of filter passageways. A plenum chamber is formed in the first member. The plenum chamber is in fluid communication with and downstream of the plurality of filter passageways. A second set of channels is formed in the generally planar surface of the first member to form, in cooperation with the generally planar surface of the second member, a plurality of nozzle outlet passageways. These nozzle outlet passageways are in fluid communication with the plenum chamber.Type: GrantFiled: November 12, 2002Date of Patent: July 24, 2007Assignee: Boehringer International GmbHInventors: Frank Bartels, Wulf Bachtler, Stephen T Dunne, Joachim Eicher, Bernhard Freund, William B Hart, Christoph Lessmoellmann

Publication number: 20060285987Abstract: A miniaturized device for pressurizing fluid. The device includes a hollow piston that provides a fluid path and a valve member. The valve member is configured for axial movement so that the valve axis remains parallel to the piston axis. The valve member is arranged at one end of the hollow piston. The valve member may be partially or completely disposed within the hollow piston. The device is particularly adapted for use in a mechanically operated atomizer to produce an inhalable aerosol of a liquid medicament without the use of propellant gas.Type: ApplicationFiled: August 9, 2006Publication date: December 21, 2006Inventors: Joachim Jaeger, Pasquale Cirillo, Joachim Eicher, Johannes Geser, Bernhard Freund, Bernd Zierenberg

Patent number: 6918547Abstract: A miniaturized device for producing high pressure in a fluid imposes stringent requirements on the manufacturing process. The device according to the invention consists of a hollow piston displaceably mounted in a cylinder and a valve member which is guided by the hollow piston and mounted so as to be axially movable relative to the hollow piston. The valve member is arranged at one end of the hollow piston inside or immediately in front of the end of the hollow piston. The device is used in a mechanically operated high pressure atomizer. This consists of a two part housing which comprises a pump housing with nozzle, a blocking mechanism, a spring housing with spring, a non-pressurized storage container for the fluid and a medical counter integrated in the spring housing. The valve operates without any auxiliary force, closes very rapidly and is sealed tight against high pressure. The atomizer is safe and simple to operate and environmentally friendly. The fluid is metered extremely accurately.Type: GrantFiled: March 24, 2004Date of Patent: July 19, 2005Inventors: Joachim Jaeger, Pasquale Cirillo, Joachim Eicher, Johannes Geser, Bernhard Freund, Bernd Zierenberg
