Abstract
An ampoule made of plasties material, for liquid or suspension pharmaceuticals, has a reservoir linked to a removable head by a channel in a neck portion. The channel has a trap, thus located between its reservoir and the head, 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.
