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.

Claims5

Dependent claims

A mixer for a charge of predetermined volume of a liquid-like consistency, said mixer comprising a frame, a composite container means on the frame for said charge comprising a lower flexible section with a lower chamber of variable volume and having an upper perimetrical edge, an upper rigid section with an upper chamber of fixed volume having a rigid cylindrical wall with a lower perimetrical edge, and an attachment joining said lower and upper sections together at said edges,

a wobble plate mounted on the bottom of the flexible section,
a wobble drive rotatably journaled in a lower portion of said frame and having a driving relationship with said wobble plate,
a motor on said frame at a location below and exterior relative to said container means,
said motor having a single direction driving connection with the wobble drive whereby to impart an oscillatory motion to the flexible section and the charge, a connection between the upper rigid section and the frame, the connection being at a location spaced from the lower perimetrical edge, the volume of the lower chamber being less than the volume of the charge, and the aggregate volumes of the chambers respectively in the lower and upper sections being such as to provide a liquid level intermediate upper and lower ends of the upper rigid section, the charge being adapted to shift cyclically between said chambers during an operation in response to action of said wobble plate.
