ABSTRACT:
A container for liquids or solids carried in liquids has a rigid upper portion and a flexible lower portion. The rigid upper portion is mounted on and supported by a frame. By having the volume of the flexible lower portion substantially less than the volume of a charge of material to be mixed and the combined volume of the lower and upper portions greater than the volume of the charge there is a constant transfer of the charge back and forth between the lower and upper portions which greatly affects the character and time for the mixing operation. Under some circumstances the flexible lower portion is surrounded by a closed chamber which may also surround the rigid upper portion, whereby the contents of the container may be subjected to one or another of a variety of conditions such, for example, as being subjected to a vacuum or negative air pressure, a positive air pressure, a controlled atmosphere such as a selected gas, or a bath of treated liquid such as a washing solution. A wobble plate on the flexible lower portion is set in motion by an electric motor to agitate the contents for the purpose of mixing.
