Abstract

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

Claims

1. A fluid supply assembly comprising:

a flexible, disposable cup having a side wall, an open outlet end, and a closed bottom defining an interior;

a disposable lid having a lid portion and an integrally connected fitting, the fitting having an opening therethrough, the disposable lid having a sealing portion at an outside of the lid portion of the disposable lid, the sealing portion adapted to fit into the open outlet end of the disposable cup, the sealing portion contacting the sidewall forming a seal with the sidewall, the seal having an area, wherein the sealing portion extends upward from the outside or downward from the outside of the lid portion of the disposable lid;

a reusable cup holder having a side wall, an open upper end, and a lower end, the reusable cup holder being adapted to receive the disposable cup, the reusable cup having a connecting surface at the upper end; and

a reusable outer lid having a lid portion and an integrally connected fitting, the fitting of the reusable outer lid having an opening therethrough, the fitting of the disposable lid adapted to fit into the fitting of the reusable outer lid, the reusable lid holder having a complementary connecting surface adapted to mate with the connecting surface on the reusable cup holder to seal the reusable cup holder and reusable outer lid together, the reusable outer lid having a projection extending downward from an underside of the lid portion of the reusable outer lid, the projection adapted to deflect the disposable lid downward, forcing the sealing portion outward against the sidewall thereby increasing the area of the seal.

2. The fluid supply assembly of claim 1 wherein the projection extends downward from the lid portion of the reusable outer lid at the fitting.

3. The fluid supply assembly of claim 1 wherein the disposable cup further comprises a flange extending outward from the sealing portion.

4. The fluid supply assembly of claim 1 wherein the reusable cup holder has a flange extending outward from the upper end.

5. The fluid supply assembly of claim 1 wherein the disposable cup, the disposable lid, the reusable outer lid, and the reusable cup holder are made of a polymeric material.

6. The fluid supply assembly of claim 1 wherein the disposable cup is made of an antistatic material.

7. The fluid supply assembly of claim 1 wherein the disposable cup has indicia for measuring fluids on the side wall.

8. The fluid supply assembly of claim 1 wherein the reusable cup holder has indicia for measuring fluids on the side wall.

9. The fluid supply assembly of claim 1 wherein the sidewall of the disposable cup has a first portion adjacent to the outlet end, a second portion adjacent to the bottom, and a third portion between the outlet end and the bottom, the first and second portions having a thickness greater than a thickness of the third portion.

10. The fluid supply assembly of claim 9 wherein the thickness of the first and second portions is in a range of about 2 to about 3 times the thickness of the third portion.

11. A fluid supply assembly comprising:

a flexible, disposable cup having a side wall, an open outlet end, and a closed bottom defining an interior;

a disposable lid having an integrally connected fitting, the fitting having an opening therethrough, the disposable lid having a sealing portion at an outer edge thereof, the sealing portion adapted to fit into the open outlet end of the disposable cup, the sealing portion contacting the sidewall forming a seal with the sidewall, the seal having an area;

a reusable cup holder having a side wall, an open upper end, and a lower end, the reusable cup holder being adapted to receive the disposable cup, the reusable cup having a connecting surface at the upper end;

a reusable outer lid having an integrally connected fitting, the fitting of the reusable outer lid having an opening therethrough, the fitting of the disposable lid adapted to fit into the fitting of the reusable outer lid, the reusable lid holder having a complementary connecting surface adapted to mate with the connecting surface on the reusable cup holder to seal the reusable cup holder and reusable outer lid together; and

a conduit having an opening therethrough, the conduit adapted to mate with the fitting of the reusable outer lid and the fitting of the disposable lid to provide a fluid connection from the interior of the disposable cup through the conduit, the opening in the conduit having a first portion ending in a ridge, the first portion having a length less than a length of the fitting of the disposable lid, the ridge adapted to engage the fitting of the disposable lid to deflect the disposable lid downward, forcing the sealing portion outward against the sidewall thereby increasing the area of the seal.

12. The fluid supply assembly of claim 11 wherein the disposable cup further comprises a flange extending outward from the sealing portion.

13. The fluid supply assembly of claim 11 wherein the reusable cup holder has a flange extending outward from the upper end.

14. The fluid supply assembly of claim 11 wherein the disposable cup, the disposable lid, the reusable outer lid, and the reusable cup holder are made of a polymeric material.

15. The fluid supply assembly of claim 11 wherein the disposable cup is made of an antistatic material.

16. The fluid supply assembly of claim 11 wherein the disposable cup has indicia for measuring fluids on the side wall.

17. The fluid supply assembly of claim 11 wherein the reusable cup holder has indicia for measuring fluids on the side wall.

18. The fluid supply assembly of claim 11 wherein the sidewall of the disposable cup has a first portion adjacent to the outlet end, a second portion adjacent to the bottom, and a third portion between the outlet end and the bottom, the first and second portions having a thickness greater than a thickness of the third portion.

19. The fluid supply assembly of claim 18 wherein the thickness of the first and second portions is in a range of about 2 to about 3 times the thickness of the third portion.
