Abstract
A disposable container, such as a deformable bag, for a fluid, having one or more inlets and one or more outlets and an impeller assembly within the container to cause mixing, dispersing, homogenizing and/or circulation of one or more ingredients contained or added to the container. The region within the container that can contain liquid is funnel shaped, which allows very low fluid level mixing, dispensing while mixing, and a reduction or elimination of vortex formation.
Claims11
A disposable container for a fluid which comprises:
- a deformable, foldable 2D bag of flexible material defining a bag volume and having a first surface and an opposite facing second surface,
- one or more inlets in said container,
- one or more outlets in said container,
- wherein first portions of said first and second surface are welded together to form at least one seal in the form of a wall separating a fluid-receiving region in said 2D bag volume from one or more non-fluid receiving regions in said 2D bag volume, and second portions of said first and second surface are welded together to form a tapered region that tapers towards said one or more outlets in said container;
- said one or more inlets in said container and said one or more outlets in said container being in fluid communication with said fluid receiving region;
- an impeller assembly having movable blades and a hood surrounding at least a portion of said moveable blades and at least partially mounted in said tapered region.
A method of mixing ingredients in a disposable container comprising a flexible material having one or more seals separating a fluid-receiving region from one or more non-fluid receiving regions, one or more inlets in said container in fluid communication with said fluid-receiving region, and one or more outlets in said container in fluid communication with said fluid-receiving region, wherein said one or more non-fluid receiving regions is triangular shaped such that said fluid-receiving region is tapered towards the one or more outlets;
- said disposable containing having one or more impeller assemblies mounted at least partially within said fluid-receiving region, said method comprising introducing said ingredients to be mixed into said container, driving said impeller assembly to agitate said ingredients, wherein said ingredients occupy said fluid-receiving region in the bag that minimizes or eliminates dead spots.
A method of mixing ingredients in a disposable container, said disposable container comprising:
- a deformable, foldable 2D bag of flexible material defining a bag volume and a first surface and an opposite facing second surface;
- one or more inlets in said container;
- one or more outlets in said container;
- wherein first portions of said first and second surfaces are welded together to form at least one seal in the form of a wall separating a fluid-receiving region in said 2D bag volume from one or more non-fluid receiving regions in said 2D bag volume, and second portions of said first and second surface are welded together to form a tapered region that tapers towards said one or more outlets in said container;
- wherein said one or more non-fluid receiving regions is triangular shaped;
- one or more impeller assemblies mounted at least partially within said fluid-receiving region;
- said method comprising introducing said ingredients to be mixed into said container and driving said impeller assembly to agitate said ingredients, wherein said ingredients occupy said fluid-receiving region in the bag that minimizes or eliminates dead spots.
