Abstract

A combination developer/absorber package for use in a diazo copy machine. The package includes a hollow package body having a vapor permeable top and bottom. A vessel of liquid ammonia is nested inside the interior of the package body and has an opening which is closed by a stopper having two bores formed therethrough. Supply and exhaust tubes extend through the bores and into the vessel for quick connection with the supply and exhaust lines of the diazo copy machine. A quantity of ammonia vapor absorbent material is disposed inside the package body between the vessel of liquid ammonia and the side wall of the container body. The package sits on top of a blower unit operatively associated with the machine so that warmed, ammonia vapor laden air passes through the absorbent material.
