A disposable liner for a pressure feed paint cup and a method for using such liner. A lid is removed from the paint cup and a disposable liner bag is inserted into the cup while an open end of the liner bag extends from the open cup end. The open liner bag end is folded over and protects the cup end and paint is poured into the liner bag. A disposable lid is placed over the open cup end and the open liner bag end is folded inwardly over the disposable lid. The paint cup lid is then attached to the paint cup, clamping the liner bag and disposable lid in place. As the paint cup lid is placed on the paint cup, a paint feed tube is pushed through an opening in the disposable lid. Optionally, a ring may be placed in a recess in the disposable lid to retain the folded liner bag end in place while the paint cup lid is attached to the paint cup. After painting, the liner and any remaining paint are disposed of.
A method for using a pressurized liquid coating material container which has a removable container lid which when secured to said container closes an open container end, said lid mounting a paint feed tube which extends through said open container end to adjacent a bottom of said container when said lid is secured to said container, said method comprising the steps of:
A disposable liner for a paint container including a paint cup having an open end and a lid adapted to be removably secured to and to close the open paint cup end, said liner comprising a disposable bag adapted to line the paint cup and to have an open end which extends from the open paint cup end, a disposable lid adapted to engage the open paint cup end, said disposable lid having an opening adapted to receive and engage a paint feed tube on the paint cup lid and having at least one vent opening, said disposable lid having a top surface with an annular step, said bag having a sufficiently large size to permit said open bag end to extend outwardly between said lid and the open paint cup end and then inwardly over said lid top and into said annular step, and an insert ring adapted to be inserted into said annular step to retain said open bag end in said annular step.
