Abstract

A fluid supply assembly. The fluid supply assembly includes a disposable cup and lid, and a reusable cup holder and outer lid.

Claims

1. A disposable lid comprising an inner portion and an outer portion, the outer portion being straight, the outer portion having an edge, the edge defining an axis parallel to a bottom of the edge, the edge of the disposable lid having an angle in a range of from about 10°

to about 70°

measured downward from the axis of the edge, the angle of the edge on the disposable lid being substantially the same as an angle of a flange on a disposable cup, the disposable lid being adapted to fit over the disposable cup, the edge of the disposable lid mating with the flange of the disposable cup, the disposable lid having a fitting integrally connected to the inner portion, the fitting extending upward from the inner portion and being generally cylindrical, the fitting being a generally cylindrical wall surrounding a generally cylindrical opening, the opening extending from the top of the fitting to the bottom.

2. The disposable lid of claim 1 wherein the disposable lid is made of a substantially transparent polymeric material, a translucent polymeric material, or an opaque polymeric material.

3. The disposable lid of claim 1 wherein further comprising a rib extending downward from an inside surface of the lid, the rib adapted to mate with an inside of the side wall of the disposable cup and form a seal.

4. The disposable lid of claim 1 wherein the edge of the disposable lid has a downwardly projecting sealing bead on an inside surface of the lid, the sealing bead adapted to contact the flange of the disposable cup.

5. The disposable lid of claim 1 further comprising a plug to close the fitting of the disposable lid.

6. The disposable lid of claim 5 wherein the plug fits inside the fitting of the disposable lid.

7. The disposable lid of claim 5 wherein the plug fits outside the fitting of the disposable lid.

8. The disposable lid of claim 1 wherein the edge of the disposable lid further comprises a removal tab.

9. The disposable lid of claim 1 wherein the inner portion of the disposable lid is generally frustoconical.

10. The disposable lid of claim 1 wherein the inner portion of the disposable lid has a generally frustoconical part extending outward from the fitting and an upwardly extending projection at an outer end of the generally frustoconical part, the upwardly extending projection being connected to the outer portion of the disposable lid.

11. A flexible, disposable cup and disposable lid for use in a reusable cup holder for a spray gun, comprising:

the disposable cup comprising a one-piece, smooth side wall, an open outlet end, and a closed bottom defining an interior, the outlet end defining an axis, and a straight flange extending outward and downward from an edge of the outlet end of the disposable cup at an angle in a range of from about 10°

to about 70°

from the axis of the outlet end, wherein the disposable cup stands on the bottom, and wherein the side wall collapses when fluid is withdrawn from the disposable cup; and

the disposable lid comprising an inner portion and an outer portion, the outer portion being straight, the outer portion having an edge, the edge defining an axis parallel to a bottom of the edge, the edge of the disposable lid having an angle in a range of from about 10°

to about 70°

measured downward from the axis of the edge, the angle of the edge on the disposable lid being substantially the same as an angle of the flange on the disposable cup, the disposable lid being adapted to fit over the disposable cup, the edge of the disposable lid mating with the flange of the disposable cup, the disposable lid having a fitting integrally connected to the inner portion, the fitting extending upward from the inner portion and being generally cylindrical, the fitting being a generally cylindrical wall surrounding a generally cylindrical opening, the opening extending from the top of the fitting to the bottom.
