Abstract
Capsules are filled with liquid-fill by introducing the liquid into a capsule body held in an upright orientation. A capsule cap is fitted over an open end of the capsule body to close the capsule. The closed capsule is held in the upright orientation until the contents have stabilised. The holding period allows excess pneumatic pressure to be dissipated prior to sealing the cap to the body. The holding period may alternatively allow solidification of the liquid-fill. Advantageously, the closed capsules are held in an upright tube (4,6) in a vertical stack.
