A connector system for a liquid container system for a spray gun includes a lid that includes a liquid outlet and an adapter. The adapter includes a spray gun end and a lid end. The ends are connected with a liquid-tight passageway. Further, the spray gun end is adapted for releasable engagement with a liquid inlet port of the spray gun and the lid end is adapted for releasable engagement with the liquid outlet. The connector system also includes a plurality of interlocking tab assemblies for releasably attaching the adapter to the lid. Each assembly includes a first tab and a second tab, wherein an end of the first tab is adapted to secure the adapter to the lid when the first tab and the second tab are interlocked.

A face mask includes a valve protector between a strap and an exhalation valve thereof. The valve protector's thickness defines a spacing between the strap and a strap retainer that is positioned on a mask body, disposed over the exhalation valve, and receives the strap. This spacing controls an extent of friction between the strap and the strap retainer.

Respirator mask

A face mask is configured to be worn on a wearer's head and to cover the wearer's nose and mouth. The face mask includes a mask body having apertures, an inhalation port positioned within one of the apertures of the mask body, an exhalation valve positioned within a second one of the apertures of the mask body, a harness assembly configured to extend about a wearer's head wherein the harness assembly includes a first strap, a strap retainer positioned on the mask body and disposed over the exhalation valve, the strap retainer configured to receive the first strap; and a valve protector positioned between the first strap and the exhalation valve.

A method of loading stacked strainers in a dispenser while minimizing strainer contamination is disclosed. The method includes providing a stack of strainers that is enclosed in a protective material to form a pod, placing the pod within a dispenser, and removing the protective material from the pod of strainers while the strainers are in the dispenser. The strainers dispensed from the thus loaded dispenser avoid being contamination during loading. The protective material may be perforated to facilitate removal from the stack, and include an extended portion to be grasped during removal from the dispenser.

A liquid container assembly for a spray gun can include a ring, a collapsible liner, and a lid for closing the open end of the liner. The ring can include a peripheral flange, a ring recess, an inner wall, and at least one rib segment extending from the inner wall. The collapsible liner can include a liner side wall formed with an open end and a liner lip at the open end. The liner can be is insertable through the ring such that the liner lip is received and supported by the ring recess. Further, the liner can be collapsible during use as liquid is removed from the liner. The lid can include at least one tab that can extend from an outer circumference of the lid. The tabs can engage the rib segments to threadably attach to the ring.

Liquid container system for a spray gun

A liquid container system for a spray gun. The container system includes an outer cup, a collapsible liner for holding a liquid to be sprayed, and a lid for closing the liner. A mounting ring may be used in the cup to make locking engagement with the lid. A lip at the open end of the liner is supported by the mounting ring. A removable lid with a liquid outlet is inserted into the mounting ring, clamping the liner lip to the mounting ring and providing for leak-free operation of the system. Alternatively, the lid may include a cylindrical portion for making sealing engagement with the open end of the liner and projection threads for locking the cup. An adapter connects the liquid outlet of the lid to the spray gun. A collar may facilitate locking engagement of the adapter with the lid.

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.
