Abstract
A connector system for attaching a liquid container to a spray gun includes a lid with a liquid outlet and an adapter that connects the outlet with the liquid inlet port of the gun. The lid includes interlocking tab assemblies for releasably attaching the adapter to the lid. The connector system combines with an outer cup, a ring for insertion into the mouth of the cup and a collapsible liner for insertion into the ring to form a liquid container system. The ring includes internal threads that cooperate with a peripheral flange on the lid to lock the lid to the ring, securing the lip of the liner. The lid includes a flexible gasket to form a liquid tight seal with the liner. The lid-liner-ring forms a liquid tight unit that may be inserted into and removed from the outer cup while containing a fluid such as paint.
