ABSTRACT:
This invention relates to a device for thoroughly mixing the liquid contents of first and second containers without exposing either the liquid contents or the resultant mixture to outside contamination. The device features a movable pumping diaphragm which traverses a pumping chamber so that the pumping chamber is divided into an upper and lower chamber. In a first position, the diaphragm causes the upper chamber to have a reduced volume while the lower chamber has an increase volume. In a second position, the pumping diaphragm causes the lower chamber to have a decreased volume while the upper chamber has an increased volume. Valving assemblies are utilized in conjunction with both the upper and lower chamber to selectively allow for the ingress and egress of fluids from these chambers dependent upon the position of the pumping diaphragm.
