Container liner and method

摘要

A disposable liner for a pressure feed paint cup (10) and a method for using it consists of inserting a disposable liner bag (28) into the cup (11) while an open end (31) of the liner bag (28) extends from the open cup end (29). The open liner bag end (31) is folded over and protects the cup end (14,29) and paint (32) is poured into the liner bag (28). A disposable lid (33) is placed over the open cup end (25) and the open liner bag end (31) is folded inwardly over the disposable lid (33). The paint cup lid (12) is then attached to the paint cup (11), clamping the liner bag (28) and disposable lid (33) in place. As the paint cup lid (12) is placed on the paint cup (11), a paint feed tube (37) is pushed through an opening (38) in the disposable lid (33). Optionally, a ring (44) may be placed in a recess (36) in the disposable lid (33) to retain the folded liner bag end (31) in place while the paint cup lid (12) is attached to the paint cup (11). After painting, the liner (28) and any remaining paint (32) are disposed of.
