The present invention relates to a method, a device, and a control program for the fluid-tight sealing of capsules containing medicaments, wherein the capsules consist of at least one capsule body and a capsule cap which are set one into the other telescopically and provided with a tight band in the abutment region on the exterior side of the capsule, wherein the capsule components are filled with gas which has a changed temperature and/or a changed pressure in relation to the environment, and wherein a reduction of the difference in pressure in the capsule occurs via gaps between capsule body and capsule cap after the capsule components have been placed one inside the other. The capsules produced via the method according to the invention are disposable capsules and preferably contain a single dose of an orally administered pharmaceutical formulation in the form of a powder or a liquid.

La présente invention concerne un procédé, un dispositif et un programme de commande pour la fermeture hermétique aux liquides de gélules contenant un médicament. Les gélules présentent au moins un corps de gélule et un capuchon de gélule, qui s'emboîtent l'un dans l'autre de manière télescopique et qui comportent, dans la zone de butée sur la surface extérieure de la gélule, un bandeau de scellage. Les parties de la gélule sont remplies d'un gaz à température et/ou à pression modifiées par rapport à l'environnement ambiant. Une réduction de pression différentielle intervient dans la gélule au moment de la séparation du corps et du capuchon de la gélule après l'assemblage par emboîtement des parties de la gélule. Les gélules fabriquées selon le procédé de l'invention sont des gélules à usage unique et contiennent de préférence une monodose de formulation pharmaceutique à administrer per os sous pulvérulente ou liquide.
