1. A mixing and dispensing apparatus comprising:
- a first closable chamber having a base and being capable of holding a liquid;
a replaceable deformable second closable chamber being capable of holding a liquid and being adapted to communicate with said first chamber; and
valve means being located at the base of said first chamber for maintaining separation between the contents of said first and second chambers when said second chamber is coupled to said first chamber, said valve means including first and second, similarly oriented one way valve members;
wherein, when said first and second chambers are coupled together and in communication, said first valve member, in response to increased pressure in said second closable chamber, allows the introduction of the contents of said second closable chamber into said first closable chamber; and
wherein said second valve member, in response to decreased pressure in said second chamber, allows the introduction of ambient air into said second chamber to equalize the pressure therein.

Abstract
A self-contained mixing and dispensing container having at least two chambers, includes a valving combination of two oppositely installed one-way valves by which fluid may be transferred from one chamber to another by deforming one chamber. One of the valves permits the transfer of fluid and the other valve, communicates with the ambient atmosphere, to permit air into the deformed chamber to replace the removed fluid.

8. A method of using a combined mixing and dispensing apparatus comprising the steps of:
-
a. affixing a replaceable deformable closable chamber containing a fluid concentrate to a fixed closable chamber having valve means; b. inverting the combined chambers to enable gravity assistance of fluid transfer; c. introducing incremental portions of the contents of said replaceable deformable closable chamber into said fixed closable chamber through said valve means with the aid of gravity; d. replacing each incremental portion as it is transferred with air through said valve means; e. emptying the contents of said replaceable deformable closable chamber over time; and f. replacing said replaceable deformable closable chamber with a new replaceable deformable closable chamber containing a fluid concentrate wherein said valve means includes first and second similarly oriented one-way valve members. - View Dependent Claims (9, 10)

11. A mixing and dispensing apparatus comprising:
-
a. a first container having at its top, means for alternatively receiving sealing means and dispensing means and, at its bottom, valve means, said valve means including a first one-way valve for introducing fluid into said first container and a second similarly oriented one-way valve communicating with the environment and coupling means; b. a second, deformable container containing concentrated fluid having at its top a dispensing opening adapted to cooperate with said first container coupling means to create a conduit between said first and second containers; whereby attaching said second container to said first container with said coupling means and inverting the combination permits fluid transfer through said first valve when said second container is deformed and, when not inverted, permits air to be admitted through said second valve and into said second container when said second container shape is restored. - View Dependent Claims (12)

13. A refillable dispenser combination comprising:
-
a. a first container having, at its top, means for receiving alternatively sealing means and dispensing means and, at its bottom, valve means, said valve means including a first one-way valve adapted to introduce fluid into said first container and a second similarly oriented, one way valve communicating with the exterior environment for drawing in ambient air when exterior pressure exceeds interior pressure; and b. a second, deformable container containing concentrated fluid and having a dispensing opening adapted to be coupled to said first container valve means in communication with said first one way valve; whereby attaching said second container to said first container, inverting the combination and deforming said second container allows transfer of the concentrated fluid of said second container into said first container through said first valve and resumption of said second container'"'"'s normal non inverted configuration allows introduction of air into said second container through said second valve.

14. A method of transferring concentrated fluid from a deformable storage container to a dispensing container including the steps of:
-
a. coupling the top of said storage container to the base of said dispensing container; b. inverting the combination; c. deforming said storage container to increase the internal pressure; d. transferring concentrated fluid under pressure from said storage container to said dispensing container through a first one way valve in the base of said dispensing container; e. restoring the combination to its non inverted configuration and releasing said storage container to permit restoration of its original conformation lowering the pressure within said storage container; and f. restoring interior pressure in said storage container by introducing air from the exterior through a second similarly oriented one-way valve in the base of said dispensing container.
