Claim:
A method of preparing a batch of paint, the method comprising: (a) providing a receptacle having an open top end; (b) providing a liner having an open end, a base, and a rim at its open end that corresponds in shape to the open top end of the receptacle, the liner being shaped to fit into the open top end of the receptacle so that a batch of paint can be added to the liner without coming into contact with the receptacle, wherein the liner is self-supporting; (c) placing the liner into the open top end of the receptacle; (d) adding a first volume of paint into the open end of the liner; and (e) fitting a lid on the open end of the liner to create a reservoir containing a batch of paint, wherein the liner is collapsible as paint is withdrawn from within the liner, and wherein the liner is removable from the receptacle together with the lid.
