Patent ID: 7288083

Claim:
A nasal-nasopharyngeal irrigating and cleansing system comprising: a cup, generally triangular in cross-section for ease in grasping by a user's hand, having: a bottom wall; a front, first and second sidewalls, said sidewalls having no openings therein and the width of said first and second sidewalls varying from a maximum width where said sidewalls join said front wall to a minimum width where said sidewalls join one another, the varying width of said sidewalls creating a horizontal sidewall as the cup is rotated from a generally upright position to a generally horizontal position for maintaining a cavity to contain the liquid held in the cup as the original first and second sidewalls no longer create a cavity for holding the liquid; a sealing rim on said front wall and extending at least partially along said first and second sidewalls, said sealing rim including an area adapted to mate with a user's facial structure to prevent further rotation of said cup on the user's face beyond a selected angle so as to maintain a sealing surface between said sealing rim and a user's face when said cup is rotated from a generally upright position to a generally horizontal position while the user's head is held at least generally upright or rearwards to allow pouring by gravity flow during rotation of the cup with regard to the user's face of a liquid held in the cup into the user's nasal and sinus cavities; a first and second protuberance on the interior side of said first and second sidewalls respectively, adapted to allow a user to select one of said protuberances to press against and close off a user's nostril allowing liquid held in the cup to flow through only the unclosed nostril into the nasal cavities.
