AMPOULES

摘要

An ampoule (10) made of plastics material, for liquid or suspension pharmaceuticals, has a reservoir linked to a removable head (13) by a channel (15) in a neck portion (12). The channel (15) has a trap, thus located between its reservoir and the head (13), in the form of an elongated restriction and/or a bend to trap liquid or suspension which may settle during storage, and prevent either reaching the head (13).
