Systems for mixing liquid solutions and methods of manufacture
First Claim
1. A system for mixing a liquid solution comprising:
- a flexible mixing bag having an interior surface bounding a compartment, the compartment being adapted to hold a liquid solution;
a mixer at least partially enclosed within the compartment of the mixing bag; and
means for raising and lowering the mixer within the compartment of the mixing bag so as to mix the solution within the compartment.

Abstract
A mixing system includes a flexible mixing bag having an interior surface bounding a compartment, the compartment being adapted to hold a liquid solution. A mixer is disposed within the compartment of the mixing bag. A shaft has a first end and an opposing second end. The first end of the shaft is connected to the mixer within the compartment of the mixing bag. The second end of the shaft is disposed outside of the compartment. A seal is formed between the mixing bag and the shaft or the mixer to enable the shaft to raise and lower the mixer within the compartment of the mixing bag while preventing leaking of the liquid solution.

11. A mixing system comprising:
-
a flexible mixing bag having an interior surface bounding a compartment, the compartment begin adapted to hold a liquid solution; and
a mixer at least partially sealed within the compartment of the bag, the mixer comprising;
a base having a plurality of fluid openings extending therethrough; and
a plurality of flaps mounted on or adjacent to the base such that when the base moves in a first direction the plurality of flaps move to allow the solution to pass through the fluid openings and when the body moves in an opposing second direction the flaps move to substantially close the fluid openings. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A mixing system comprising:
-
a flexible mixing bag having an interior surface bounding a compartment, the compartment begin adapted to hold a liquid solution, the mixing bag having an upper end and an opposing lower end;
a mixer disposed within the compartment of the mixing bag;
a shaft having a first end and an opposing second end, the first end of the shaft being connected to the mixer within the compartment of the mixing bag, the second end of the shaft being disposed outside of the compartment; and
means for enabling the shaft to raise and lower the mixer within the compartment of the mixing bag while preventing leaking of the liquid solution from the compartment of the mixing bag. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)

28. A method for manufacturing a mixing system, the method comprising:
-
seaming together a plurality of panels so as to from a mixing bag bounding a compartment, each panel being comprised of flexible sheet;
prior to completing the seaming of the plurality panels, inserting within the compartment a mixer assembly, the mixer assembly comprising a mixer having a shaft projecting therefrom, a free end of the shaft being advanced through an outlet on the mixing bag so that the mixer is disposed within the compartment and the free end of the shaft is disposed outside of the compartment; and
forming a liquid tight seal between the mixer assembly and the mixing bag so that fluid dispensed into the compartment cannot flow out through the outlet. - View Dependent Claims (29, 30, 31, 32, 33, 34)

35. A method for manufacturing a mixing system, the method comprising:
-
seaming together a plurality of panels so as to from a mixing bag bounding a compartment, the compartment communicating to the exterior through an outlet, each panel being comprised of flexible sheet;
prior to completing the seaming of the plurality panels, inserting within the compartment a mixer; and
forming a liquid tight seal between the mixer and the mixing bag so that fluid dispensed into the compartment of the mixing bag cannot flow out through the outlet thereof. - View Dependent Claims (36, 37, 38, 39, 40)
