Abstract
A container system includes a substantially rigid container having a floor and a side wall upstanding therefrom. The side wall and floor bound a chamber. A magnetic mixer is disposed below the floor of the container. A mixing bag assembly is disposed within the chamber of the container. The mixing bag assembly includes a collapsible body having a first end and an opposing second end. The collapsible body bounds a compartment. A mixing dish is disposed at the second end of the collapsible body so as to communicate with the compartment thereof. A magnetic stir bar is disposed on the mixing dish.
Claims38
A mixing bag assembly comprising:
- a body bounding a compartment, the body being comprised of a flexible sheet;
- a mixing dish secured to the body, the mixing dish having a floor and an annular side wall upstanding from the floor, the floor being in communication with the compartment of the body, and the side wall terminating at a perimeter edge, the perimeter edge being secured to the body, the side wall and the floor of the mixing dish bounding a cavity;
- a magnetic stir bar disposed within the cavity;
- and
- a retention cover mounted to the mixing dish so as to further bound the stir bar within the cavity, the retention cover having at least one opening extending therethrough.

A container system comprising:
- a substantially rigid container having a floor, an upper side wall upstanding therefrom, and a lower side wall downwardly extending from the floor, the upper side wall and floor bounding a first chamber, and the lower side wall bounding a second chamber;
- a magnetic mixer disposed below the floor of the container, the magnetic mixer being at least partially disposed within the second chamber;
- and
- a mixing bag assembly at least partially disposed within the first chamber of the container, the mixing bag assembly comprising:
- a collapsible body bounding a compartment, the body having a first end and an opposing second end, at least a portion of the second end of the body resting on or adjacent to the floor of the container,
- a mixing dish being more rigid than the collapsible body, the mixing dish being secured at the second end of the collapsible body;
- and
- a magnetic stir bar disposed on the mixing dish.
5 more elements
A method comprising:
- inserting a disposable mixing bag assembly within a substantially rigid container, the container having a floor with an opening extending therethrough, a magnetic stir bar being disposed within a compartment of the mixing bag assembly so that the stir bar is aligned with the opening on the floor of the container;
- delivering a solution or at least two separate components into the compartment of the mixing bag assembly, at least one of the at least two separate components being a liquid;
- and
- activating a magnetic mixer disposed below the opening on the floor of the container so as to cause rotation of the magnetic stir bar within the mixing bag assembly, the magnetic stir bar stirring the solution or the at least two separate components, wherein the mixing bag assembly comprises:
- a body bounding the compartment, the body being comprised of at least one flexible sheet;
- a mixing dish secured to the body, the mixing dish having a floor and an annular side wall upstanding therefrom, the side wall and the floor of the mixing dish bounding a cavity, the magnetic stir bar being disposed within the cavity, the act of inserting comprising at least partially positioning the mixing dish within the opening on the floor of the container;
- and
- a retention cover mounted to the mixing dish so as to further bound the stir bar within the cavity, the retention cover having at least one opening extending therethrough.
5 more elements
A mixing bag assembly comprising:
- a body bounding a compartment, the body being comprised of at least one flexible sheet;
- a mixing dish assembly at least partially disposed on the body and at least partially bounding a cavity, a plurality of openings being formed on the mixing dish assembly, each opening providing fluid communication between the cavity of the mixing dish assembly and the compartment of the body;
- and
- a magnetic stir bar disposed within the cavity of the mixing dish assembly.

A container system comprising:
- a substantially rigid container having a floor and an upper side wall upstanding therefrom, the upper side wall and floor bounding a first chamber;
- a magnetic mixer disposed below the floor of the container;
- and
- a mixing bag assembly at least partially disposed within the first chamber of the container, the mixing bag assembly comprising:
- a collapsible body bounding a compartment, the body having a first end and an opposing second end, at least a portion of the second end of the body resting on or adjacent to the floor of the container,
- a mixing dish being more rigid than the collapsible body, the mixing dish comprising an annular side wall extending between a floor and a perimeter edge, the perimeter edge being secured to the second end of the body, the side wall and the floor of the mixing dish bounding a cavity;
- and
- a magnetic stir bar disposed within the cavity;
- and
- a retention cover mounted to the mixing dish so as to further bound the stir bar within the cavity, the retention cover having at least one opening extending therethrough.
