Abstract

A fluid supply assembly. The fluid supply assembly includes a disposable cup and lid, and a reusable shell and outer lid. A flexible, disposable cup, a reusable shell, and a method of preparing a fluid supply assembly for use with a fluid supply applicator are also described.

Claims

1. A shell for a fluid supply assembly comprising:

a tubular, polygon-shaped sleeve having at least three faces, the sleeve having an open bottom, a pair of ribs on the outside of the shell extending toward each other from each edge of one face, wherein the ribs do not extend beyond a circumference of a circle having a diameter that passes through the edges of the faces;

a cylindrical flange at the upper end of the sleeve, the flange having a connecting surface adapted to mate with a complementary connecting surface on a lid.

2. The shell of claim 1 wherein the faces of the sleeve are curved.

3. The shell of claim 1 wherein the sleeve and the flange are separate pieces attached by at least one connection.

4. The shell of claim 3 wherein the connection is selected from snap connections, screws, rivets, welding, adhesive, or combinations thereof.

5. The shell of claim 3 wherein the sleeve or the flange or both has at least one stop to prevent rotation of the pieces during use.

6. The shell of claim 1 wherein the connecting surface and complementary connecting surface are selected from lugs and grooves, threaded connections, pins and slots, or combinations thereof.

7. The shell of claim 1 further comprising a measuring guide positioned between the pair of ribs.

8. A fluid supply assembly comprising:

a flexible, disposable cup having a side wall, an open outlet end, and a closed bottom defining an interior, and a lip extending outward from an edge of the outlet end of the disposable cup, wherein the lip of the disposable cup has at least two sealing beads, the sealing beads having a length;

a reusable shell for a fluid supply assembly comprising a tubular, polygon-shaped sleeve having at least three faces, the sleeve having an open bottom; and

a cylindrical flange at the upper end of the sleeve, the flange having a connecting surface adapted to mate with a complementary connecting surface on a lid, the flange of the shell supporting the lip of the disposable cup, the shell being adapted to receive the disposable cup;

a disposable lid adapted to fit over the disposable cup, the disposable lid having a fitting with an opening therethrough, wherein the disposable lid has a sealing flange with at least two indentations, the indentations having a shape matching a shape of the sealing beads, a length of the indentations being smaller than the length of the sealing beads; and

wherein the sealing beads on the lip of the disposable cup engage the indentations on the sealing flange of the disposable lid, and the sealing beads spread the indentations, each sealing bead forming at least two sealing points; and

a reusable outer lid adapted to mate with the flange of the shell, the reusable outer lid having a fitting with an opening therethrough, the fitting of the disposable lid adapted to fit into the fitting of the reusable outer lid, and a complementary connecting surface on the reusable outer lid adapted to mate with the connecting surface of the shell to seal the shell and reusable outer lid together.

9. The fluid supply assembly of claim 8 wherein the faces of the sleeve are curved.

10. The fluid supply assembly of claim 8 wherein the connecting surface and complementary connecting surface are selected from lugs and grooves, threaded connections, pins and slots, or combinations thereof.

11. The fluid supply assembly of claim 8 wherein a pair of ribs extends toward each other from each edge of one face.

12. The fluid supply assembly of claim 8 wherein the sidewall of the disposable cup has a protrusion extending around the circumference of the disposable cup.

13. The fluid supply assembly of claim 12 wherein the protrusion is a spiral around the disposable cup.

14. The fluid supply assembly of claim 12 wherein the protrusion is at least one circle around the disposable cup.

15. The fluid supply assembly of claim 8 wherein the shape of the sealing beads is selected from half of an ellipse along the longer axis, or a hemisphere.

16. A fluid supply assembly comprising:

a flexible, disposable cup having a side wall, an open outlet end, and a closed bottom defining an interior, and a lip extending outward from an edge of the outlet end of the disposable cup;

a reusable shell for a fluid supply assembly comprising a tubular, polygon-shaped sleeve having at least three faces, the sleeve having an open bottom, a pair of ribs on the outside of the shell extending toward each other from each edge of one face, wherein the ribs do not extend beyond a circumference of a circle having a diameter that passes through the edges of the faces; and

a cylindrical flange at the upper end of the sleeve, the flange having a connecting surface adapted to mate with a complementary connecting surface on a lid, the flange of the shell supporting the lip of the disposable cup, the shell being adapted to receive the disposable cup;

a disposable lid adapted to fit over the disposable cup, the disposable lid having a fitting with an opening therethrough; and

a reusable outer lid adapted to mate with the flange of the shell, the reusable outer lid having a fitting with an opening therethrough, the fitting of the disposable lid adapted to fit into the fitting of the reusable outer lid, and a complementary connecting surface on the reusable outer lid adapted to mate with the connecting surface of the shell to seal the shell and reusable outer lid together.

17. The fluid supply assembly of claim 16 wherein the faces of the sleeve are curved.

18. The fluid supply assembly of claim 16 wherein the sidewall of the disposable cup has a protrusion extending around the circumference of the disposable cup.

19. The fluid supply assembly of claim 18 wherein the protrusion is a spiral around the disposable cup.

20. The fluid supply assembly of claim 18 wherein the protrusion is at least one circle around the disposable cup.

21. The fluid supply assembly of claim 16 wherein the lip of the disposable cup has at least two sealing beads, the sealing beads having a length;

wherein the disposable lid has a sealing flange with at least two indentations, the indentations having a shape matching a shape of the sealing beads, a length of the indentations being smaller than the length of the sealing beads; and

wherein the sealing beads on the lip of the disposable cup engage the indentations on the sealing flange of the disposable lid, and the sealing beads spread the indentations, each sealing bead forming at least two sealing points.

22. The fluid supply assembly of claim 21 wherein the shape of the sealing beads is selected from half of an ellipse along the longer axis, or a hemisphere.

23. A fluid supply assembly comprising:

a flexible, disposable cup having a side wall, an open outlet end, and a closed bottom defining an interior, and a lip extending outward from an edge of the outlet end of the disposable cup, wherein the lip of the disposable cup has at least two sealing beads, the sealing beads having a length;

a reusable shell for a fluid supply assembly, the shell having an open bottom and a flange at the upper end, the flange having a connecting surface adapted to mate with a complementary connecting surface on a lid, the flange supporting the lip of the disposable cup, the shell being adapted to receive the disposable cup;
