Patent number: 4192309Abstract: A breath-actuated inhalation device for dispensing a powdered medicament from a powdered medicament-holding capsule, comprising an elongate housing having a passageway for the movement of air therethrough, one end of the housing being an output end adapted for insertion into a user's mouth or nasal passage, the passageway having an inlet end terminating in an emptying chamber at the output end of said housing, the cross-sectional area of the passageway being less than the cross-sectional area of the emptying chamber, and means associated with said housing for receiving a powdered medicament-holding capsule. A collar surrounds at least a portion of the periphery of the housing adjacent the emptying chamber and has at least one substantially flat surface with a notch therein, which allows a first, smaller part of a two-part capsule to fit therein but which is too small to allow the second, larger part of the capsule to fit therein.Type: GrantFiled: September 5, 1978Date of Patent: March 11, 1980Assignee: Syntex Puerto Rico, Inc.Inventor: Boyd J.

Patent number: 4174238Abstract: A thermoplastic pharmaceutical solution container includes a neck portion having at least one port through the neck portion. A thermoplastic port protector or closure covers the port and defines a frangible section. The closure has a length to diameter ratio providing good mechanical advantage leverage to rupture the frangible section when the closure is pushed sideways. A seal is formed with the closure by forcing a die heated above the melting point of the plastic material into the neck portion, removing a portion of the port protector and forming a depression. The frangible section is formed in the vertical side wall of the depression.Type: GrantFiled: January 25, 1978Date of Patent: November 13, 1979Assignee: Baxter Travenol Laboratories, Inc.Inventors: Thomas A. Fowles, David A. Winchell

Patent number: 4161257Abstract: The neck of a bottle is closed and sealed by a one-piece cap having a cylrical portion which surrounds the neck, a deformable end wall which extends across the open end of the neck, and a flexible hose which is integral with the end wall. The inner side of the end wall has an annular bead which sealingly engages the inner surface of the neck when the pressure in the interior of the bottle is reduced below atmospheric pressure. An annular groove at the inner side of the end wall surrounds the bead and communicates with the atmosphere by way of at least one channel in the cylindrical portion. The groove communicates with the atmosphere during expulsion of air from the bottle, for example, in response to heating, but is sealed from the interior of the bottle when the end wall bulges inwardly and maintains the bead in sealing engagement with the neck.Type: GrantFiled: May 24, 1977Date of Patent: July 17, 1979Assignee: Genossenschaft Vebo Solothurnische Eingliederungs-Statte fur BehinderteInventor: Hermann Hauri

Patent number: 4152378Abstract: A screw top closure for a container opening defining a helically threaded neck, and a rotatable screw top positioned to permit rotation by the screw top between outward and inward positions on the neck. A sealing partition is positioned across the opening of the neck. In accordance with this invention, an aperture is defined in the sealing partition, the aperture being positioned in off-center relation to the rotational axis of the screw top. A sealing cap member is positioned across the aperture, with a rupturable seal, facing the screw top. A projection is defined on the side of the screw top facing the partition, being positioned to be longitudinally spaced from the sealing cap member when the screw top is in the outward position, and to engage the sealing cap member when the screw top is rotationally advanced to its inward position. Accordingly, the seal between the cap member and the partition may be ruptured in aseptic manner by the projection, to open the aperture.Type: GrantFiled: March 14, 1977Date of Patent: May 1, 1979Assignee: Baxter Travenol Laboratories, Inc.Inventors: John L. Vcelka, David A. Winchell

Patent number: 4138565Abstract: Solutions of certain hydrogenated ergopeptide alkaloids in mixtures of pharmacologically acceptable alcohols and water have improved stability. Preferred solvents are mixtures of ethanol, propylene glycol and glycerol containing from 15-40% wt. of water and having dielectric constants between 34 and 46. With these solutions it is not essential to carry out the filing operation under an inert atmosphere.Type: GrantFiled: September 15, 1977Date of Patent: February 6, 1979Assignee: Sandoz Ltd.Inventors: Lothar Ehrhardt, Ludwig Patt, Volker Hartmann

Patent number: 4119544Abstract: A device which is adapted to receive a liquid having particles suspended therein includes a one-piece plastic container having an open top, a closed bottom, and an endless side wall extending between the open top and closed bottom to define with the bottom of the container a hollow interior thereof. A partition structure which is integral with the side wall of the container is situated between the open top and closed bottom thereof to define in the interior of the container upper and lower chambers separated from each other by the partition structure. This partition structure extends across the interior of the container and has therein a free edge defining with an inner surface of the side wall of the container an opening through which the above chambers communicate with each other.Type: GrantFiled: April 26, 1977Date of Patent: October 10, 1978Assignee: The Purdue Frederick CompanyInventor: Ernst Vesely

Patent number: 4089432Abstract: A closure structure for a vial or container, preferably of the two-compartment type, wherein lyophilized medication is contained in one compartment and a solvent is contained in the other compartment with a displaceable, moistureproof plug disposed between the two compartments. The closure structure is comprised of a stopper which is partially inserted into the neck of a vial and is covered by a cap member having a fastening portion for securing the cap member to the open end of the vial neck and a sleeve portion of reduced diameter which snugly surrounds the protruding portion of the stopper and is disconnectible from the fastening portion in order to move with the protruding portion of the stopper into the neck of the bottle under manually applied pressure. A dust shield is secured to the free end of the sleeve portion and is preferably removed after which the needle of a syringe can be inserted through the stopper to communicate with the interior of the vial.Type: GrantFiled: May 6, 1977Date of Patent: May 16, 1978Assignee: The Upjohn CompanyInventors: Gary K.

Patent number: 3948261Abstract: The disclosure is directed to a container for unit doses of dry vaccines which are to be administered on the surface of the skin. The unit dose container is made up of a rigid receptacle and a compressible closure which supports a bifurcated needle bearing dried vaccine. The closure is adapted to support the needle in the container during a lyophilizing process while liquid vaccine is dried on the needle. The closure has grooves which in one position of the closure relative to the receptacle permit the vaporized liquid from the vaccine to be withdrawn from the receptacle during lyophilizing. In another position the closure seals the container. The move from the first position to the second position is accomplished merely by pressing on the end of the closure.Type: GrantFiled: November 27, 1974Date of Patent: April 6, 1976Assignee: American Home Products CorporationInventor: Dale C. Steiner
