A preformed paint tray with peelable liners is made from a planar tray substrate with upper and lower surfaces and a plurality of stacked liner sheets with peelable adhesive on one surface by positioning the liner sheets adjacent a surface of the substrate, and simultaneously thermoforming the substrate and sheets together to form a substrate having a shaped interior, with the sheets conforming to the shaped interior of the substrate. The sheets are maintained in the thermoformed shape by their adherence to the other sheets and the substrate. If desired, the sheets can include tear tabs to facilitate separation of the top sheet from the other sheets. The tray can be cleaned of residual paint after use by simply peeling away the upper liner sheet.

What is claimed is: 1. A paint tray comprising: a) a tray-shaped substrate having a top side including a concave interior surface and a bottom side for supporting the paint tray when it rests on a supporting surface; and b) a plurality of peelable liner sheets including a bottom sheet, each sheet conforming to the shape of the top side, including substantially the entire interior surface, and having a lower surface and an upper surface, the lower surface of each sheet other than the bottom sheet being releasibly adhered to the upper surface of the underlying sheet with a peelable adhesive on substantially the entire lower surface of the sheet, the lower surface of the bottom sheet being releasibly adhered to the interior surface with a peelable adhesive on substantially the entire lower surface of the bottom sheet. 2. The paint tray of claim 1, wherein the bottom sheet is not adhered to any portion of the bottom side of the substrate. 3. The paint tray of claim 1, wherein the bottom sheet comprises a tab that is not adhered to the substrate. 4. The paint tray of claim 3, wherein the peelable adhesive adheres the entirety of the lower surface of the bottom sheet, other than the tab, to the interior surface. 5. The paint tray of claim 3, wherein each of the sheets comprises a tab that is not adhered to the surface underlying the tab. 6. The paint tray of claim 1, wherein the substrate is a thermoformed plastic. 7. The paint tray of claim 1, having at least three peelable liner sheets. 8. The paint tray of claim 1, having at least five peelable liner sheets. 9. The paint tray of claim 1, wherein each of the substrate and the sheets is a thermoformed plastic. 10. The paint tray of claim 1, wherein the substrate is made from a different material than the sheets. 11. The paint tray of claim 1, wherein each of the sheets comprises a tab that is not adhered to the substrate or to the upper surface of any other sheet. 12. The paint tray of claim 1, wherein the shape of the interior surface includes two paint wells divided by a flat section. 13. The paint tray of claim 1, further comprising feet on the bottom side of the paint tray.
