Patent ID: 8888752

Claim:
A vessel for use in rinsing a user's nasal passage comprising a main body having an exterior surface; a spout extending off the main body; an elastomeric nozzle attached to the spout, the elastomeric nozzle defining an outer skirt having a free end and being deflectable upon engagement with the walls of the user's nasal cavity; the main body having gripping indentations along opposing sidewalls thereof; and a vacuum breaker valve formed in a top portion of the main body for manual actuation by the user to control the flow of a fluid positioned in the vessel out of the nozzle, the vacuum breaker valve comprising a valve body; and a top flange that extends downward and outward from a top potion of the valve body and engages the exterior surface of the main body to operate as a biasing mechanism for the valve body by maintaining the valve body in a closed position; wherein to move the vacuum breaker valve to an open position, the valve body is downwardly compressed by a user, causing the of the top flange to splay outward and slide along the exterior surface of the main body; and in the open position the vacuum breaker valve allows airflow into the main body to provide a constant fluid flow out of the elastomeric nozzle.
