School Inequality: What Do We Know

A plastic dispenser case for small items, such as hearing aid battery cells, consisting of a hollow plastic body to receive the cells and a plastic overlay cover having integral peripheral hinged panels to serve as individual doors to spaces in the hollow body, and as latches for clamping onto the hollow body, so the body and the cover are held tightly rigid, while permitting access through each separate door to remove a cell, with windows provided in position to permit a probe to engage one control terminal of a selected cell, with a sheet of dessicant material metallized on one surface to engage all the cell outer shells as the other terminal of the cells, for access as a common electrode by an external probe, thereby permitting testing of the individual cells in the dispenser case with the cells all assembled.
