Pediatric dosing dispenser
View Patent ↗A package that is configured to store and dispense fluids. The package includes a container and a dosing dispenser for closing an opening to the container. The dosing dispenser includes a body portion having a syringe receiver and a valve assembly that is configured to permit the flow of fluid from the container to the syringe.
1. A dosing dispenser for dosing a liquid into a syringe comprising
a body portion including a top wall formed to include a syringe receiver, the body portion adapted to mate with a discharge outlet formed on a container, and an annular side wall appended to the top wall and arranged to extend downwardly and away from the top wall and to cooperate with the top wall to form an interior region, and
a valve assembly positioned within the interior region of the body portion, the valve assembly including a valve with a dome-shaped surface and a biasing member coupled to the valve, the biasing member configured to bias the valve to a closed position to seal the syringe receiver to prevent the flow of liquid,
wherein insertion of a portion of the syringe into the syringe receiver causes the valve to move from the closed position to an opened position to permit the flow of liquid from the container and into the syringe and removal of the syringe from the syringe receiver causes the valve to return to the closed position to prevent the further release of liquid from the container,
wherein the dome-shaped surface of the valve seals the syringe receiver.
2. The dosing dispenser of claim 1 , wherein the top wall is formed to include a valve seat that is configured to accept at least a portion of the valve from the valve assembly.
3. The dosing dispenser of claim 2 , wherein the valve includes a sealing region that sealingly engages with the valve seat to form a seal to prevent the unwanted discharge of liquid from syringe receiver.
4. The dosing dispenser of claim 2 , wherein the valve includes a domed upper surface and a concave lower surface, the valve being formed from a deformable material to permit the valve to conform to the shape of the valve seat.
5. The dosing dispenser of claim 2 , wherein the valve assembly includes an assembly ring that is configured to be coupled to the top wall of the body portion to retain the valve assembly to the body portion.
6. The dosing dispenser of claim 5 , wherein the top wall includes an annular mounting lock that is configured to secure an assembly ring to the top wall of the dosing dispenser.
7. The dosing dispenser of claim 6 , wherein the mounting lock reduces in diameter as it extends away from the inside surface of the top wall and is configured to receive an outer surface of the attachment ring to hold the attachment ring in position against the top wall of the body portion.
8. The dosing dispenser of claim 5 , wherein the biasing member includes a series of elongated flexible connectors that extend radially from the valve to the attachment ring and are arranged to permit axial movement of the valve.
9. The dosing dispenser of claim 1 , wherein the valve includes a domed upper surface having an annular sealing region.
10. The dosing dispenser of claim 9 , wherein the valve includes a sealing region and at least one flow channel that is configured to permit fluid to flow from the container and into the syringe when the valve is in the opened position.
11. The dosing dispenser of claim 10 , wherein the at least one flow channel does not extend through the sealing region of the valve.
12. A dosing dispenser for dosing a liquid into a syringe comprising
a body portion including a top wall formed to include a syringe receiver, the body portion adapted to mate with a discharge outlet formed on a container, and an annular side wall appended to the top wall and arranged to extend downwardly and away from the top wall and to cooperate with the top wall to form an interior region, and
a valve assembly positioned within the interior region of the body portion, the valve assembly including a valve and a biasing member coupled to the valve, the biasing member configured to bias the valve to a closed position to seal the syringe receiver to prevent the flow of liquid,
wherein insertion of a portion of the syringe into the syringe receiver causes the valve to move from the closed position to an opened position to permit the flow of liquid from the container and into the syringe and removal of the syringe from the syringe receiver causes the valve to return to the closed position to prevent the further release of liquid from the container,
wherein the valve assembly includes an attachment ring and the biasing member includes a cantilever arm that couples the valve to the attachment ring.
13. The dosing dispenser of claim 12 , wherein the position of the cantilever arm is retained by at least one retainer so that the valve is positioned radially inwardly of the attachment ring.
14. The dosing dispenser of claim 12 , wherein when the valve assembly is in a molded position, the cantilever arm and the valve are positioned radially outwardly from the attachment ring.
15. The dosing dispenser of claim 14 , wherein when the valve assembly is in a use position, the cantilever arm and valve are positioned radially inwardly from the attachment ring.
16. The dosing dispenser of claim 12 , wherein the cantilever arm and valve are pivotable about an arc of the attachment ring.
17. A dosing dispenser for dosing a liquid into a syringe comprising
a body portion including a top wall formed to include a syringe receiver, the body portion adapted to mate with a discharge outlet formed on a container, and an annular side wall appended to the top wall and arranged to extend downwardly and away from the top wall and to cooperate with the top wall to form an interior region,
a valve assembly positioned within the interior region of the body portion, the valve assembly including an attachment ring, a valve with a dome-shaped surface, and at least one biasing member that is adapted to couple the valve to the attachment ring, the biasing member configured to bias the valve to a closed position to seal the syringe receiver to prevent the flow of liquid,
the top wall including a mounting lock that is configured to secure the attachment ring to top wall of dosing dispenser, and
wherein insertion of a portion of the syringe into the syringe receiver causes the valve to move from the closed position to an opened position to permit the flow of liquid from the container and into the syringe and removal of the syringe from the syringe receiver causes the valve to return to the closed position, wherein the dome-shaped surface of the valve seals the syringe receiver to prevent the further release of liquid from the container.
18. The dosing dispenser of claim 17 , wherein the at least one biasing member is in the form of a series of elongated flexible connectors that extend radially from the valve to the attachment ring and are arranged to permit axial movement of the valve.
19. The dosing dispenser of claim 17 , wherein the valve includes a sealing region and at least one flow channel that is configured to permit fluid to flow from the container and into the syringe when the valve is in the opened position.
20. The dosing dispenser of claim 19 , wherein the at least one flow channel does not extend through the sealing region of the valve.
21. The dosing dispenser of claim 19 , wherein the mounting lock reduces in diameter as it extends away from an inside surface of the top wall and is configured to receive an outer surface of the attachment ring to hold the attachment ring in position against the top wall of the body portion.
22. The dosing dispenser of claim 17 , wherein the dome-shaped valve includes a plurality of channels configured to permit fluid to flow from the container and into the syringe when the valve is in the opened position.
23. The dosing dispenser of claim 22 , wherein the plurality of channels are radially inside of and do not extend through the sealing region of the valve.
