Abstract

A rechargeable dispensing system for dispensing a liquid product has a recharge container, a platform base, a locking mechanism, and a pump. The recharge container has a primary finish and a valve. The base has a receptacle for receiving the primary finish of the recharge container and a fluid connector located within the base and attached to the receptacle. The locking mechanism secures the recharge container to the base, wherein the valve is in a closed position when the locking mechanism is engaged and in an open position when the locking mechanism is disengaged. The pump is attached to the base in open communication with the recharge container along the fluid connector for dispensing the liquid product from the recharge container.

Claims

1. A container for use with a docking station adapted to receive said container, said container comprising:

a) a handle;

b) a primary finish comprising a finish recess; and

c) a spiral valve associated with said primary finish such that an interior volume of said container is defined by said spiral valve and said primary finish, said spiral valve being adapted such that the interior volume of said container is in fluid communication with said docking station through said spiral valve when said container is received in said docking station.

2. The container of claim 1, wherein said valve is a spiral valve having a plate attached to a ring with at least three shape memory bands, said post displacing said plate when the container engages the receptacle.

3. The container of claim 1, wherein said container further comprises a liquid having at least 40% suspended solids.

4. The container of claim 1, further comprising a second finish having a vent.

5. A rechargeable dispensing system comprising:

a) a container according to claim 1; and

b) a docking station comprising a receptacle adapted to receive said container, a locking mechanism to secure said container to said docking station; and

c) a discharge spout in fluid communication with said docking station;

wherein said valve in said container is opened such that the interior volume of said container is in fluid communication with said receptacle of said docking station through said valve when said container is received in said receptacle of said docking station.

6. A rechargeable dispensing system, comprising:

a container having a primary finish with a recess;

a docking station having a receptacle for receiving said container, a locking mechanism for securing said container to said docking station, wherein said locking mechanism includes a rotatable actuator positioned within said receptacle having at least one camming surface and a ring positioned within said actuator having at least one finger, and wherein said camming surface engages said finger when said actuator is rotated so that said finger is biased into engagement with said recess of said container to secure said container to said docking station; and

a discharge spout in fluid communication with said receptacle.

7. The recharge dispensing system of claim 6, wherein said container further comprises a liquid having at least 40% suspended solids.

8. The recharge dispensing system of claim 7, wherein said liquid has a viscosity of between 1000 centipoise and 3500 centipoise.

9. The recharge dispensing system of claim 8, wherein said liquid is an anhydrous laundry detergent.

10. The recharge dispensing system of claim 6, wherein said receptacle further comprises a spring-biased seal which is opened by said container when said container engages said receptacle.

11. The recharge dispensing system of claim 10, wherein said container further comprises a valve having a post, wherein said post engages said seal to open said seal when said container engages said receptacle.

12. The recharge dispensing system of claim 11, wherein said valve is a spiral valve.

13. The recharge dispensing system of claim 12, wherein said spiral valve comprises a plate attached to a ring with at least three shape memory bands, said post displacing said plate when said container engages said receptacle.

14. The recharge dispensing system of claim 6, wherein said receptacle further comprises a post for opening a valve of said container when said container engages said receptacle.

15. The recharge dispensing system of claim 14 wherein said valve is a spiral valve.

16. The recharge dispensing system of claim 15 wherein said spiral valve comprises a plate attached to a ring with at least three shape memory bands.

17. The recharge dispensing system of claim 6, wherein said container further comprises a secondary finish having a vent.

18. The recharge dispensing system of claim 6, further comprising a pump in fluid communication with said discharge spout and said receptacle.
