Abstract
An ampoule made of plastics 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.
Claims16
An ampoule made of plastics material, comprising:
- a body comprising a reservoir containing up to 10 ml of a suspension of a pharmaceutical;
- a removable head portion comprising a bulb;
- and
- a neck portion linking the body to the head, comprising a channel through which liquid in the reservoir can exit the ampoule once the head has been removed,
- wherein the bulb is in fluid communication with the channel of the neck portion, and has a diameter greater than the diameter of the channel of the neck portion, and
- wherein the neck portion comprises a particulate trap which prevents solid material held in suspension in the liquid from settling in the part of said ampoule which is removed on opening, and wherein the particulate trap is formed by a U-bend in the channel of the neck portion.
