A respirator system has a vapor filter which includes a body for holding a vapor filter media, a first integral male connector for attachment to a particle filter, and a second integral female connector on an opposing side for connecting to a respirator mask. The particle filter has a complementary female connector and the mask has a complementary male connector for attachment to the vapor filter body. Alternately, a circumferential lip of the vapor filter and a sealing surface or a retainer sealingly attach a particle filter pad to the vapor filter. A method of assembly includes providing a vapor filter with an integral connector for attaching to a particle filter, providing a complementary connector and connecting the vapor filter to the particle filter.
A connector system for attaching a liquid container to a spray gun.

The lid includes interlocking tab assemblies (250-252) for releasably attaching the adapter to the lid. Each tab assembly includes two tabs, with one tab adapted to secure the adapter to the lid when the tabs are interlocked. 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 or segments 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 thus forms a liquid tight unit that may be inserted into and removed from the outer cup while containing a fluid such as paint.
