Abstract

A hermetically sealed thermoplastic container or ampoule having a hollow body portion, a neck portion unitary with the body portion and terminating in a circumferential, inwardly extending sealing flange, and a removable cap. The neck portion defines an access passageway to the hollow body portion configured as a Luer female fitting adapted to receive a Luer male connector when the access passageway is open. The outer surface of the neck portion is provided with lugs for engaging a Luer lock male connector and the like.

Claims

1. A hermetically sealed container of a thermoplastic material and comprising a hollow body portion, a neck portion unitary with the body portion and terminating in a circumferential, inwardly extending sealing flange, and a removable cap joined to the sealing flange by a frangible web unitary with the removable cap and with the sealing flange;

the neck portion defining an access passageway to the hollow body portion which includes a throat region configured as a Luer female fitting dimensioned to receive a Luer male connector when the access passageway is open.

2. The hermetically sealed container in accordance with claim 1 further provided with a pair of opposed external lugs on the neck portion below the sealing flange.

3. The hermetically sealed container in accordance with claim 2 wherein said throat region is axially spaced from the opposed external lugs.

4. The hermetically sealed container in accordance with claim 1 wherein said sealing flange has a quadrilateral cross-section.

5. The hermetically sealed container in accordance with claim 1 wherein said sealing flange has a trapezoid cross-section.

6. The hermetically sealed container in accordance with claim 5 wherein said trapezoid has a proximal base adjacent to the neck portion and an opposed distal base.

7. The hermetically sealed container in accordance with claim 6 wherein the proximal base of the trapezoid is approximately two times longer than the distal base of the trapezoid.

8. The hermetically sealed container in accordance with claim 6 wherein the distal base of the trapezoid does not overlap the proximal base of the trapezoid.

9. The hermetically sealed container in accordance with claim 1 further provided with a tab unitary with the removable cap.
