Patent ID: 8590278

Claim:
Method for the fluid-tight sealing of capsules containing medicaments, wherein the capsules consist of at least a capsule body and a capsule cap, as capsule parts, which are placed telescopically one inside the other to provide a contact surface therebetween, such that the capsule has defined gaps of 20 microns to 50 microns along the contact surface and wherein bulges or dimples are stamped into the capsule body or capsule cap, where they contact when sealed, to provide said gaps, characterised by the steps of: filling the capsule parts with a gas that is at a different temperature or pressure or both than the temperature or pressure or both outside the capsule; fitting the capsule parts together such that a differential pressure reduction in the capsule through said gaps between the capsule body and capsule cap results; and providing a leak-tight seal in said gaps by applying a sealing solution to the circumference of the capsule, wherein the sealing solution has a viscosity of 150 cP to 250 cP, such that the sealing solution penetrates into the gaps as a result of capillary effect.
