Claims :

1. A liquid containing thermoplastic unit dose container which comprises a body portion, a neck portion and an outlet opening at the end of the neck portion which is sealed by a non resealable cap, wherein the outside wall of the neck portion comprises a thread engagement portion which is located at or proximate the outermost edge of the neck portion so that after removal of the cap the thread engagement portion is adapted to engage within an inwardly facing screw thread channel at the end of a syringe, thus enabling sealing connection of the container to the said syringe so that liquid within the container may be directly transferred from the container to the syringe.
2. A container as claimed in claim 1 wherein the outside wall of the container neck comprises a thread engagement portion and a non engagement portion, said thread engagement portion being adapted to engage in the screw thread channel at the end of said syringe and said non engagement portion being shaped so that it does not interfere with the screw thread when the container is connected to the syringe.
3. A container as claimed in claim 2 wherein the thread engagement portion is located at the edge of the outlet opening and comprises a shoulder shaped to fit within the screw thread channel at the end of the syringe.
4. A container as claimed in any one of the previous claims wherein the neck portion is in the shape of an inverted truncated cone and the edge of the outlet opening is shaped to engage with the screw thread channel at the end of the syringe .
5. A container as claimed in any one of claims 1 to 3 wherein the neck portion has parallel sides.
6. A container according to any one of the previous claims wherein the top of the body is hexagonal and strengthened by one yoke on each side.
7. A container according to any one of the previous claims wherein the outlet opening is formed such that it is adapted to be screw threadingly engaged with a luer lock fitting.
8. A container as claimed in any one of the previous claims wherein the container is adapted to be connected to a syringe with a fitting comprising a central cone surrounded by a peripheral wall having an inwardly facing screw thread, characterized by the internal diameter of the neck portion of the container being less than or equal to the corresponding outside diameter of the central cone at at least one portion of the container neck.
9. A container as claimed in claim 8 wherein the engagement portion of the neck is greater in cross sectional diameter than the distance between opposite sides of the peripheral wall on the syringe to which it is intended to connect the container.
10. A container as claimed in any one of the previous claims wherein the non resealable cap is attached to the outlet opening along a weakened section.
11. A container substantially as hereinbefore described with reference to what is shown in any one of the accompanying drawings.
