SQUEEZE BOTTLE FOR SINUS CAVITY RINSE
First Claim
1. An article for rinsing a user'"'"'s nasal cavity comprisinga main body defining a reservoir for receiving a liquid, the main body having resiliently deformable walls, the main body having an upper opening defined by a rim;
- a nozzle having an outer wall forming a tip and defining an aperture formed therein, an inner wall forming a fluid passageway in communication with the aperture and extending inside the outer wall, a void space being formed between the outer wall and the inner wall;
a check valve housing in fluid communication with the nozzle and a liquid delivery tube extending into the reservoir;
a collar removably connectable with the upper opening of the main body, the collar coupling the nozzle and the check valve to the upper opening of the main body when the collar is connected with the upper opening;
a first opening formed through the check valve housing to allow communication between the reservoir of the main body and the void space in the nozzle;
a second opening formed through the check valve housing to allow fluid communication between the exterior of the main body with the reservoir of the main body; and
a valve associated with the second opening to allow fluid to flow from an area exterior to the main body into the reservoir.

Abstract
A vessel for use in rinsing a user'"'"'s nasal cavity provides a resiliently collapsible main body, a self-sealing nozzle that increases in internal pressure when the vessel is squeezed, and a check valve in the nozzle to reduce back-wash into the vessel. A collar connects the nozzle and check valve to the main body. The check valve includes a first opening that provides fluid communication between the main body and a void formed in an interior of the nozzle and may allow pressure within the nozzle to increase upon deforming the main body. A second opening may provide fluid communication between an exterior of the main body and a fluid reservoir formed in the main body. The second opening may cooperate with a valve that allows selective fluid communication between the exterior of the main body and the reservoir formed in the main body.
