Patent number: 7213511Abstract: Apparatus for producing image bearing filled gelatin capsules (12 and 16) for directing gelatin ribbon (2,4) from respective casting drums to an encapsulation station (6). Along the path of at least one ribbon (4) is a transfer station (18) at which images are applied to the ribbon. The images are applied in a pattern which corresponds to the pattern of capsules formed from the ribbon at the encapsulation station (6). Both the rollers (8) at the encapsulation station, and a support roller at or adjacent the transfer station are positively drive, and a control system ensures that the peripheral speed of a support roller (16) in the transfer station (18) is the same as the speed of the ribbon into and through the encapsulation station. The drive motor for the respective support roller in the transfer station is preferably a stepping motor, adjustable to advace or retard relative to the ribbon spped in the encapsulation station (6).Type: GrantFiled: September 6, 2002Date of Patent: May 8, 2007Assignee: R.P.

Patent number: 7121822Abstract: The invention herein relates to a method and apparatus for forming (or cold-forming) an embossed blister from a laminated film wherein an indicia is formed on the base of the blister. In particular, the invention involves a single pass process of combining the formation of a blister and the formation of an indicia (embossing) on the blister, wherein the blister-forming pin contains a face with an indicia and is adapted to controllably stretch the laminated film during blister formation to minimize stretching of the film at the base of the blister. The invention is particularly useful in manufacturing processes which involve the formation of blisters having laminated films which contain a metal foil and polymer layer, wherein improved control in the stretching of the laminate during blister formation is desirable.Type: GrantFiled: February 13, 2002Date of Patent: October 17, 2006Assignee: R.P. Scherer CorporationInventor: Kenneth Heath

Patent number: 6509040Abstract: The present invention relates to fast dispersing solid dosage forms that preferably dissolve in the oral cavity within sixty (60), more preferably within thirty (30), most preferably within ten (10) seconds. A novel feature of the solid dosage forms according to the invention reside in the fact that the composition is essentially free or absolutely free of mammalian gelatin. It has been discovered that the use of certain modified starches at concentrations from 20 to 90% by weight of the solid dosage form prepares dosage forms that are mechanically and chemically stable and are able to deliver higher concentrations of an active ingredient than the heretofore utilized gelatin based fast dispersing solid dosage forms. Further, the solid dosage forms according to the invention are obtainable by removing a solvent, such as water, from a mixture comprising an active ingredient, a modified starch and a matrix forming agent via freeze drying.Type: GrantFiled: June 22, 2001Date of Patent: January 21, 2003Assignee: R.P. Scherer CorporationInventors: Owen James Murray, Richard Green, Patrick Kearney, Leon Paul Grother

Patent number: 6425888Abstract: A unit container for a treatment fluid comprises a sealed enclosure of which one wall section thereof is formed with at least one opening. The enclosure is pressuriseable to discharge its contents through the opening or openings, which is or are of sufficient diameter to enable the generation of a jet and/or discrete droplets of treatment fluid discharged therefrom. The one wall section is typically a flat section of the enclosure wall, and the enclosure is typically a blister pack, with the wall section at a planar base of the blister. However, the one wall section may be dome-shaped and formed with at least one opening in the top region of the dome. Containers of the invention may be provided in packages, for example in strip form or in planar arrays. Dispensing devices are described for discharging their contents in treatment.Type: GrantFiled: August 11, 1997Date of Patent: July 30, 2002Assignee: R. P. Scherer CorporationInventors: Jonathan K.

Patent number: 6423342Abstract: A process for the preparation of a solid pharmaceutical dosage form comprising a carrier and, as active ingredient, a compound which exists, in solution, in an equilibrium between a free acid or free base form and a salt form, and for which there is a difference in volatility between the free acid or free base form and the salt form. The process includes the steps of solidifying a mixture of the compound and carrier in a solvent, and subsequently removing the solvent from the solidified mixture. A pH modifier is added to the mixture prior to solidification to shift the equilibrium to favor the less volatile form of the active ingredient.Type: GrantFiled: May 4, 1999Date of Patent: July 23, 2002Assignee: R. P. Scherer CorporationInventors: Andrew William Jordan, Joy Elaine Saunders, Patrick Kearney

Patent number: 6212791Abstract: The invention permits the application of an identifying mark onto a fast-dissolving dosage form without the need for application of pressure or printing directly onto the dosage unit. The invention comprises preparing of a fast-dissolving dosage unit that is embossed with an identifying mark such as a manufacturer's logo, medicinal component strength, or other information relating to the unit. The desired identifying mark is first embossed onto the base of the container such as a blister pocket. Liquid suspension is then filled into the container and solidified, e.g., freeze-dried, therein. The resulting dosage unit in the container is thereby embossed with a substantial copy of the identifying mark that was embossed on the base of the container. The embossed identifying mark on the base of the container remains thereon as well thereby affording the ability to learn the identifying mark on the enclosed unit without opening the packet.Type: GrantFiled: March 31, 2000Date of Patent: April 10, 2001Assignee: R.P. Scherer CorporationInventors: Andrew R. Thompson, Richard J. Yarwood, Patrick Kearney
