A nasal irrigator mainly includes a saline container having an upward inclined bottom conduit, a lower cap connected to a free end of the conduit, and a plug fitted around a front tube portion of the lower cap for extending into a patient's nostril. The tube portion of the lower cap is provided around an outer periphery of a front end with an annular rib. A stopper is fixed in and projected forward from the front end of the tube portion such that a passage is formed between the stopper and the tube portion. The plug has a front head portion provided with an axial through hole and a rear sleeve portion adapted to fitly put around the tube portion of the lower cap. The plug may be pushed toward the lower cap so that the stopper extends into and blocks the through hole of the plug, and saline in the container could not be supplied into the plug via the through hole. And, the plug may be pulled forward relative to the lower cap until an annular groove in the sleeve portion engages with the annular rib around the front end of the tube portion, so that saline in the container could be supplied to the plug via the conduit, the passage between the stopper and the tube portion of the lower cap, and the through hole in the head portion of the plug.

[ What is claimed is:] [1.]1. A nasal irrigator, comprising:a container for containing a predetermined amount of saline or other cleaning liquid therein for cleaning a patient's nostril, and being provided at a lower end thereof with a conduit which extends downward and then bends to incline upward at an angle, to define an open free end;a lower cap fitted at a rear side thereof to said open free end of said conduit of said container, a front side of said lower cap extending forward to form a tube portion having an annular rib provided around an outer periphery of a front end thereof, a stopper diametrically smaller than said tube portion being fixed in the front end of said tube portion, such that said stopper projects from said front end of said tube portion with a passage being formed between said stopper and said tube portion to communicate an interior of said tube portion with a space outside said tube portion; anda plug for extending into a patient's nostril, said plug including a front head portion provided with an axially extended through hole into which said stopper of said lower cap may be extended to block said through hole, and a rear sleeve portion being dimensioned to movably fit around said tube portion of said lower cap and having a pair of radially inward projected annular flanges provided around an inner peripheral wall of said sleeve portion at a predetermined position to define an annular groove between said pair of annular flanges;whereby when said plug is turned while pushed toward said lower cap, said stopper of said lower cap is brought into a position in said through hole of said plug to block and seal said through hole, thereby bringing said nasal irrigator into a closed state; and when said plug is turned while pulled in a direction opposite to said lower cap until said annular groove in said sleeve portion engages with said annular rib around the front end of said tube portion of said lower cap, said stopper is brought to a position a distance away from said through hole, so that the saline or other cleaning liquid in said container is allowed to flow into the patient's nostril via said conduit, said passage between said stopper and said tube portion of said lower cap, and said through hole of said plug, bringing said nasal irrigator into an open state.
