Bottle for sinus cavity rinse

摘要

A vessel for use in rinsing a user's nasal cavities includes a main body, a spout, a self-sealing nozzle, and a flow control valve actuable by the user. The spout extends off of the main body and the elastomeric nozzle attached to the spout defines an outer skirt having a deflectable free end upon contact with the walls of the user's nasal cavity. A vacuum breaker valve is formed in a top portion of the main body for actuation by the user to control the flow of a fluid positioned in the vessel out of the nozzle. The main body may include gripping indentations along opposing sidewalls thereof. The spout may be integrally formed with the main body, and the spout and the nozzle may be detachably connected.

1. 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; anda 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; whereinto 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; andin the open position the vacuum breaker valve allows airflow into the main body to provide a constant fluid flow out of the elastomeric nozzle.
