Abstract

Claims (27)

1. A dosing dispenser comprising

a body portion including a top wall formed to include an opening, 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 away from the top wall and cooperate with the top wall to form an interior region,

a valve assembly configured to be inserted into and positioned within the opening of the top wall, the valve assembly including a syringe receiver and a valve formed to include a slit and first and second flexible side walls,

wherein the slit is movable from a closed position to an opened position and the first and second flexible side walls of the valve are adapted to bias the slit to the closed position.

2. The dosing dispenser of claim 1 , wherein the valve assembly includes a body portion formed to include the syringe receiver.

3. The dosing dispenser of claim 2 , wherein the body portion of the valve assembly includes an upper flange adapted to be positioned at an upper surface of the top wall of the body portion.

4. The dosing dispenser of claim 3 , wherein the body portion of the valve assembly includes a lower flange adapted to be positioned at a lower surface of the top wall of the body portion.

5. The dosing dispenser of claim 4 , wherein the upper and lower flanges form an annular recess that is adapted to be positioned with the opening of the top wall.

6. The dosing dispenser of claim 4 , wherein the lower flange includes a tapered side wall that is adapted to allow the valve assembly to be inserted into the opening of the top wall.

7. The dosing dispenser of claim 6 , wherein the lower flange includes a planar upper wall that is adapted to be positioned against the top wall of the body portion.

8. The dosing dispenser of claim 4 , wherein the upper flange has an outer diameter that is greater than an outer diameter of the lower flange.

9. The dosing dispenser of claim 1 , wherein the first and second flexible side walls are interconnected by a pair of side edges.

10. The dosing dispenser of claim 9 , wherein the first flexible side wall includes a first face and the second flexible side wall includes a second face and the first and second faces are interconnected by a pair of edges.

11. The dosing dispenser of claim 10 , wherein the first and second faces are separated by the slit and when the first and second faces are in a first position the slit is in the closed position and when the first and second faces are in a second position the slit is the open position.

12. A dosing dispenser comprising

a body portion including a top wall formed to include an opening 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 flip top cap coupled to the body portion, the flip top cap adapted to cover the top wall when in a closed position and exposing the top wall when in an open position,

a valve assembly configured to be inserted into and positioned within the opening of the top wall, the valve assembly including a syringe receiver and a valve formed to include a slit and first and second flexible side walls, first and second flexible side walls of valve are adapted to bias the slit to a closed position to form a seal to limit the flow of liquid,

wherein insertion of a portion of a syringe into the syringe receiver causes the slit to move from the closed position to an opened position to permit the flow of liquid through the slit, and removal of the syringe causes the slit to return to the closed position to limit the further release of liquid through the slit.

13. The dosing dispenser of claim 12 , wherein flip top cap includes a plug adapted to be positioned with the syringe receiver when the flip top cap is in the closed position to seal the syringe receiver to limit unwanted fluid flow.

14. The dosing dispenser of claim 12 , wherein the valve assembly includes a body portion formed to include the syringe receiver.

15. The dosing dispenser of claim 14 , wherein the body portion of the valve assembly includes an upper flange adapted to be positioned at an upper surface of the top wall of the body portion.

16. The dosing dispenser of claim 15 , wherein the body portion of the valve assembly includes a lower flange adapted to be positioned at a lower surface of the top wall of the body portion.

17. The dosing dispenser of claim 16 , wherein the upper and lower flanges form an annular recess that is adapted to be positioned with the opening of the top wall.

18. The dosing dispenser of claim 16 , wherein the lower flange includes a tapered side wall that is adapted to allow the valve assembly to be inserted into the opening of the top wall.

19. The dosing dispenser of claim 18 , wherein the lower flange includes a planar upper wall that is adapted to be positioned against the top wall of the body portion.

20. The dosing dispenser of claim 16 , wherein the upper flange has an outer diameter that is greater than an outer diameter of the lower flange and the first and second flexible side walls are interconnected by a pair of side edges.
