Abstract
A cap assembly for closing an opening in a vessel may include a stopper and a rigid cap adapted to fit over the stopper and onto a vessel. The stopper may include a polymer body adapted to fit an opening of the vessel and a tubular portion defining an internal passageway extending through the polymer body. The rigid cap may include a pressure based locking mechanism adapted to engage the vessel under a unidirectional force and a tamper evident feature.

A cap assembly for closing an opening in a vessel, the cap assembly comprising:
- a stopper comprising a polymer body adapted to fit an opening of a vessel, wherein the stopper further comprises a tubular portion defining an internal passageway extending through the polymer body;
- and
- a rigid cap adapted to fit over the stopper and onto the vessel, wherein the cap comprises:
- a pressure based locking mechanism;
- and
- a tamper evident feature.
A method for forming a cap assembly, the method comprising:
- forming a stopper including an polymer body adapted to fit an opening of a vessel, the stopper also including a tubular portion which defines an internal passageway extending through the elastomer body;
- and
- forming a rigid cap attached to and integral with the stopper, wherein the rigid cap is adapted to fit over the stopper and onto the vessel, wherein the cap comprises:
- a pressure based locking mechanism;
- and
- a tamper evident feature.
