Liquid container system for a spray gun

A liquid container assembly for a spray gun comprising:

• a cup having a bottom and an open top, the top including a cup lip, the cup lip including a cup lip recess formed on an inner periphery of the cup lip;
• a mounting ring, the ring including a peripheral flange and a ring recess, the peripheral flange insertable into the cup lip recess;
• a liner having an open top, for holding a liquid, wherein the liner is collapsible during use as the liquid is removed from the liner;
• and
• a lid for closing the open top of the liner,
• wherein the lid has at least one thread for threadable engagement with the mounting ring, and
• the mounting ring peripheral flange and the cup lip recess are shaped such that relative rotation of the mounting ring and cup is prevented after insertion of the peripheral flange into the cup lip recess.

A liquid container assembly for a spray gun comprising:

• a cup having a bottom and an open top;
• a mounting ring disposed within an interior of the cup proximate the open top;
• a collapsible liner having an opening, the liner insertable through the mounting ring and supported thereby within the cup such that no portion of the liner contacts the cup, wherein the liner is collapsible during use as the liquid is removed from the liner;
• and
• a lid removably covering the opening in the liner,
• wherein the lid has at least one thread for threadable engagement with the mounting ring, and
• the mounting ring and the cup are configured such that relative rotation of the mounting ring and the cup is prevented after insertion of the mounting ring into the cup.

A liquid container assembly for a gravity feed spray gun comprising:

• a lid including a liquid outlet;
• a generally cylindrical adapter, the adapter including a spray gun end and a lid end, the ends connected with a liquid-tight passageway, the spray gun end releaseably engageable with a liquid inlet port of the spray gun, the lid end releaseably coupleable with the liquid outlet;
• a collar, the collar releasably attaching the adapter to the lid by rotation of the collar with respect to the lid;
• a liner forming an enclosure with the lid, and
• a cup configured to receive the liner,
• wherein the lid seals with the liner and wherein the lid has at least one thread for threadable engagement with a mounting ring disposed within an open top of the cup, and the mounting ring and the cup are configured such that rotation of the mounting ring with respect to the cup is prevented after insertion of the mounting ring into the cup and the liquid container assembly is adapted to allow liquid to flow therefrom in an inverted position such that the liquid container assembly is disposed above the spray gun during use.

A liquid-tight container assembly, comprising:

• a collapsible liner having a liner body defined by an open top, a peripheral sidewall and a closed bottom, said open top defined by an outwardly projecting peripheral lip, wherein the liner is collapsible during use;
• a lid covering said open top of said liner, said lid having a peripheral flange sized to extend over said peripheral lip of said liner, said lid further having outwardly projecting tabs, said lid further having an outlet;
• a ring having an annular recess defining an opening, said liner body extending through said opening, said peripheral lip of said liner received and supported by said annular recess, said ring further having inwardly projecting threads cooperating with said outwardly projecting tabs of said lid to secure said lid, liner and ring together as a unitized lid-liner-ring assembly;
• and
• an outer cup within which the unitized lid-liner-ring assembly is received,
• wherein the ring and the outer cup are configured such that rotation of the ring with respect to the outer cup is prevented after insertion of the ring into the outer cup,
• rotation of said lid with respect to said ring causes an underside of the peripheral flange of the lid to be forced downwardly against a top surface of the peripheral lip of the liner thereby creating a liquid tight seal between the lid and the liner, and
• said lid includes a filter.

A liquid container assembly for a spray gun, comprising:

• a generally cylindrical cup having a bottom and an open top, the top including a cup lip, the cup lip including a cup lip recess;
• a mounting ring, the ring including a peripheral flange and a ring recess, the
• peripheral flange insertable into the cup lip recess;
• a collapsible liner having a liner lip at an open end, the liner insertable through the mounting ring such that the bottom side of the liner lip is received and supported by the ring recess;
• a removable lid for closing the top of the liner, wherein the ring recess includes rib segments on an inner wall of the ring recess and the lid includes a plurality of tabs, the tabs engageable with the rib segments to threadably attach the lid to the mounting ring, and the mounting ring peripheral flange and the cup lip recess are shaped such that relative rotation of the mounting ring and cup is prevented after insertion of the peripheral flange into the cup lip recess;
• a generally cylindrical adapter, the adapter having a spray gun end and a cup end, the ends connected with a liquid-tight passageway, the spray gun end releasably engageable with a liquid inlet port of the spray gun, the cup end releasably engageable with the liquid outlet of the lid;
• and
• a collar releasably securing the cup end of the adapter to the liquid outlet.
