Abstract
A liquid containing thermoplastic unit dose container (1) which comprises a body portion (2), a neck portion (3) and an outlet opening (7) at the end of the neck portion (3) which is sealed by a non-resealable cap (4). The outside wall of the neck portion (3) comprises a thread engagement portion (8) which is located at or proximate the outermost edge of the neck portion (3) so that after removal of cap (4) thread engagement portion (8) is adapted to engage within an inwardly facing screw thread channel (14) at the end of a syringe. This enables sealing connection of the container (1) to the syringe so that liquid within container (1) may be directly transferred from the container (1) to the syringe.

A liquid drug-containing thermoplastic unit dose container for engaging and transferring liquid to a syringe of a standard size appropriate for administering the particular drug, the syringe being of the type which has a central projecting cone, an outer peripheral wall surrounding the cone, and a bottom wall together defining an annular channel, wherein the outer peripheral wall contains an inwardly facing screw thread for engaging a needle fitting;
- wherein said container comprises:
- a body portion containing said dose;
- an outlet comprising a hollow neck portion sized to receive the cone of a mating syringe and to extend up into the annular channel, the neck portion having an outwardly facing surface, an internal surface and an outermost rim;
- and
- a removable, non-resealable cap secured to said rim for sealing the outlet;
- wherein the outwardly facing surface of the neck portion comprises a thread engagement portion for engaging the inwardly facing screw thread of the mating syringe, such that the cap may be removed and the syringe screwed onto the container neck portion, and wherein the neck portion includes means for providing a seal between the container and the syringe cone, when the syringe is screwed onto the container, so that liquid may be directly transferred from the container to the syringe.
In combination a syringe and a liquid drug-containing thermoplastic unit dose container for engaging and transferring liquid to the syringe, wherein the syringe comprises a central projecting cone, an outer peripheral wall surrounding the cone, and a bottom wall together defining an annular channel, wherein the outer peripheral wall contains an inwardly facing screw thread for engaging a needle fitting;
- and wherein said container comprises:
- a body portion containing said dose;
- an outlet comprising a hollow neck portion sized to receive the cone of the syringe and to extend up into the annular channel, the neck portion having an outwardly facing surface, an internal surface, and an outermost rim;
- and
- a removable, non-resealable cap secured to said rim for sealing the outlet;
- wherein the outwardly facing surface of the neck portion comprises a thread engagement portion for engaging the inwardly facing screw thread of the mating syringe, such that the cap may be removed and the syringe screwed onto the container neck portion, and wherein the neck portion includes means for providing a seal between the container and the syringe cone, when the syringe is screwed onto the container, so that liquid may be directly transferred from the container to the syringe.
A method of providing a liquid drug dose to a syringe, comprising the steps of:
- providing a syringe having a central projecting cone, an outer peripheral wall surrounding the cone, and a bottom wall together defining an annular channel, wherein the outer peripheral wall contains an inwardly facing screw thread for engaging a needle fitting;
- providing a liquid drug-containing thermoplastic unit dose container comprising a body portion containing said dose;
- an outlet comprising a hollow neck portion sized to receive the cone of the syringe and to extend up into the annular channel, the neck portion having an outwardly facing surface, an internal surface, and an outermost rim;
- and a removable, non-resealable cap secured to said rim for sealing the outlet;
- wherein the outwardly facing surface of the neck portion comprises a thread engagement portion for engaging the inwardly facing screw thread of the mating syringe, and wherein the neck portion includes means for providing a seal between the container and the syringe cone, when the syringe is screwed onto the container;
- removing the cap from the container to expose the container rim;
- screwing the syringe onto the container neck so as to form a seal between the container and syringe cone, and transferring liquid from the container to the syringe.
