Claims
- 1. A container, comprising: a hollow body terminating in a radially inwardly directed lip defining an opening at one end; a nozzle having a discharge end and an opposite end having an annular groove for engagement with said lip to position said nozzle on said hollow body; cooperating thread means on a cap and said nozzle for positioning said cap in a sealed position in the container; cooperative ring and groove means on said nozzle and cap above said thread means adapted to provide an audible signal upon seating of said cap on said nozzle in a sealed position; said nozzle having a radially outwardly directed flange and said hollow body having an annular interior shoulder, whereby said flange and said shoulder cooperatively support said nozzle on said hollow body without misalignment; and check valve means mounted in the interior of said nozzle for permitting flow of hollow body contents substantially only out of said hollow body while preventing return flow of said contents into said hollow body, said check valve means including a first annular disk having a hinged central portion for movement into and out of transverse alignment with said flow of contents from said hollow body, and a second annular disk having an open central portion smaller than said first annular disk for providing a valve seat to prevent movement of said first disk inward of said transverse alignment.
- 2. The combination, comprising:
- a container having a nozzle with a discharge end;
- a cap cooperatively engaging said container and having a seal for sealing engagement with said discharge end of said nozzle;
- cooperating thread means on said cap and nozzle for positioning said cap in a sealed position on said container;
- cooperative ring and groove means on said nozzle and cap above said thread means adapted to provide an audible signal upon sealing of said cap on said nozzle in a sealed position;
- check valve means comprising a first annular disk having a hinged central portion for movement into and out of transverse alignment with the flow of contents from said container; and
- a second annular disk having an open central portion smaller than said first annular disk for providing a valve seat to prevent movement of said first disk inward of said transverse alignment.
- 3. The device of claim 2 wherein said nozzle includes an interior annular groove for supporting and locating said second disk on the periphery thereof.
- 4. The device of claim 3 wherein said first disk includes an annular outer ring for supporting said hinged central portion, said annular outer ring being positioned on said second disk by said interior annular groove on said nozzle.
- 5. The device of claim 4 wherein said annular outer ring and second disk snap fit in said interior annular groove.
- 6. The combination, comprising:
- a container having a nozzle with a discharge end;
- a cap cooperatively engaging said container and having a seal for sealing engagement with said discharge end of said nozzle;
- cooperating thread means on said cap and nozzle for positioning said cap in a sealed position in said container;
- cooperative ring and groove means on said nozzle and cap above said thread means adapted to provide an audible signal upon sealing of said cap on said nozzle in a sealed position;
- said nozzle being tapered from said cooperative ring and groove means to the open end of said nozzle; and
- a first inwardly lacing locating ring on said cap cooperatively tapered for guiding the nozzle discharge end to engage said seal.
- 7. The combination, comprising: a container having a nozzle with a discharge end; a cap cooperatively engaging said container and having a seal for sealing engagement with said discharge end of said nozzle; cooperating thread means on said cap and nozzle for positioning said cap in a sealed position in said container; and cooperative ring and groove means on said nozzle and cap adapted to provide an audible signal upon seating of said cap on said nozzle in a sealed position.
- 8. The combination as claimed in claim 7, wherein the groove means comprises a circumferentially extending groove on the outer peripheral surface of the nozzle adjacent the thread means on the nozzle and the ring comprises a circumferentially extending rib on the interior of the cap adjacent the threads on the cap.
- 9. The combination as claimed in claim 7, wherein the thread means are located adjacent the lower end of the nozzle and cap and wherein the cooperating ring and groove means are located above the thread means on the cap and nozzle.
