Sealing coaxial telescoping cap and body of capsules

摘要

Coaxial cap (11) and body (12) parts of a capsule (10) which overlap when telescopically joined are sealed by distributing a sealing fluid between overlapping parts and drying, at room temp. or with thermal energy. The cap part has on its inner surface a ridge or an arrangement of ridge segments (15) or protrusions, and spaced therefrom towards the open end of the cap/part there is provided an arrangement (24) to hold the cap and body exactly coaxial.
