Abstract

A person having diabetes will often be required to take both slow acting and fast acting forms of insulin. It is important to be able to distinguish readily between medicament cartridges containing different medicaments. The present invention enables a user to distinguish readily between medicament cartridges containing different medicaments. A medicament cartridge and adaptor top assembly is provided, the medicament cartridge comprising a cylinder having a bottleneck provided with a flange at a first end, a fluid impermeable membrane covering the first end, a cap beaded under the flange to retain the fluid impermeable membrane in place, and a piston displaceably located within a second end of the cylinder, and the adaptor top comprising a sleeve having a body portion and a tapered portion, the tapered portion being provided with a smaller diameter end, the smaller diameter end being located beneath the cap.

Claims

1. A medicament cartridge and adaptor top assembly comprising a medicament cartridge that comprises a cylinder having a bottleneck provided with a flange at a first end, a fluid impermeable membrane covering the first end, a cap beaded under the flange to retain the fluid impermeable membrane in place, a piston displaceably located within a second end of the cylinder and an adaptor top that comprises a sleeve having a body portion and a tapered portion, the tapered portion being provided with a smaller diameter end, the smaller diameter end being located beneath the cap.

2. An assembly according to claim 1, in which the adaptor top is provided with information regarding the contents of the medicament cartridge.

3. An assembly according to claim 2, in which the adaptor top is colour coded to provide the information regarding the contents of the medicament cartridge.

4. An assembly according to claim 1, in which the tapered portion comprises a plurality of fingers extending from the body portion.
