Abstract
A parenteral vial, stopper and cap assembly comprises a vial having a body defining an interior, and an opening leading to the interior. The assembly further comprises a stopper configured to sealingly engage the opening, a cap configured to cover the opening and the stopper. The stopper and the cap fit together to form an integral unit configured to cap the vial. The cap moves with respect to the vial between a partially engaged position that permits gas flow out from the vial interior, and a fully engaged position in which the stopper sealingly engages the opening.

A parenteral vial, stopper and cap assembly, comprising:
- a vial having a body defining an interior, and an opening leading to the interior;
- a stopper configured to sealingly engage the opening;
- and
- a cap configured to cover the opening of the vial and the stopper, the cap including a main body formed as a tubular wall and a cover configured to fit over the tubular wall, a hinge pivotally attaches the cover to the main body, the hinge being a double hinge that includes a first pivot axis and a second pivot axis;
- wherein the stopper and the cap fit together to form an integral unit;
- wherein the cap moves with respect to the vial between a partially engaged position that permits gas flow out from the vial interior, and a fully engaged position in which the stopper sealingly engages the opening;
- and
- wherein the hinge is configured to be broken to serve as a tamper evident feature.
