Abstract
(A1) Ein zur Lagerung und Bereitstellung von gefrorenen Partikeln geeigneter Kryobehaelter, umfassend ein thermisch isolierendes Behaelterelement, das mindestens einen Aufnahmeraum fuer gefrorene Partikel und mindestens eine Austrittsoeffnung aufweist, eine Verschlussvorrichtung, mit der die mindestens eine Austrittsoeffnung verschliessbar ist, mindestens ein Oeffnungselement, welches betaetigbar ist, um eine Austrittsoeffnung zu oeffen und dadurch die gefrorenen Partikel ausserhalb der Austrittsoeffnung bereitzustellen, und ein Isolationselement zur thermischen Isolierung der Verschlussvorrichtung. Die Erfindung betrifft ausserdem ein Magazin zur Bereitstellung von gefrorenen Partikeln fuer eine Depositionsvorrichtung, eine Depositionsvorrichtung mit Magazin und ein Verfahren zur Bereitstellung von gefrorenen Partikel fuer eine Deposition.

 

DE 102008031666 A1 UPAB: 20100127 NOVELTY - The cryogenic container (40) comprises a thermally insulated container element (41) having an accommodation chamber (41a) for frozen particles (50) and an outlet opening (41b), a locking device, by which the outlet opening is closed, an opening element (43), which is actuated to open the outlet opening to provide the frozen particles outside of the outlet opening, an insulation element for the thermal insulation of the locking device, a fixing element for fixing the opening element in an inactive condition, a removable foil envelope, and a display element. DETAILED DESCRIPTION - The cryogenic container (40) comprises a thermally insulated container element (41) having an accommodation chamber (41a) for frozen particles (50) and an outlet opening (41b), a locking device, by which the outlet opening is closed, an opening element (43), which is actuated to open the outlet opening to provide the frozen particles outside of the outlet opening, an insulation element for the thermal insulation of the locking device, a fixing element for fixing the opening element in an inactive condition, a removable foil envelope, and a display element for displaying whether the cryogenic container exceeds a predetermined temperature. The insulation element is removable from the cryogenic container. The opening element is arranged to move the frozen particles contained in the accommodation chamber to the outlet opening during the operation and to mechanically open the locking device during the operation. The locking device comprises a foil. The opening element is actuated by pressure, is an insertion bolt, which projects into the accommodation chamber and results a breaking-through of the locking device during its actuation, is dimensioned, so that it completely projects through the accommodation chamber, and is thermally insulated. INDEPENDENT CLAIMS are included for: (1) a depot for providing frozen particles for a deposition device; (2) a deposition device having a depot; and (3) a method for providing frozen particles for a deposition device. USE - Cryogenic container useful in a deposition device for storing and providing frozen particles (claimed) for medical and biological applications. ADVANTAGE - The cryogenic container is easy to handle thus avoiding danger of interruptions of the cool chain and delays, which can rapidly lead to a melting of the particles, protects the frozen particles against contamination and moisture, and is capable of effectively and safely storing and providing the frozen particles, so that the particles greatly reach the target substrate in a frozen state.
