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 method of preparing a fluid supply assembly for use with a fluid supply applicator comprising:

providing 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, wherein the sealing portion extends upward from the outside or downward from the outside of the lid portion;

a reusable cup holder 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 reusable lid holder having a complementary connecting surface, the reusable outer lid having a projection extending downward; and

a conduit having an opening therethrough,

placing the disposable cup in the reusable cup holder;

filling the disposable cup with fluid;

placing the disposable lid on the disposable cup, the sealing portion of the disposable lid fitting into the open outlet end of the disposable cup, the sealing portion contacting the sidewall forming the seal with the sidewall, the seal having an area;

attaching the reusable outer lid to the reusable cup holder, the fitting of the disposable lid being inside of the fitting of the reusable outer lid, the projection engaging the disposable lid and deflecting the disposable lid downward, forcing the sealing portion outward against the sidewall thereby increasing the area of the seal; and

attaching the conduit to the fitting of the reusable outer lid.

2. The method of claim 1 wherein the projection extends from the fitting.

3. The method of claim 1 wherein the disposable cup further comprises a flange extending outward from the sidewall at the open outlet end.

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

5. The method 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 method of claim 1 wherein the disposable cup is made of an antistatic material.

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

8. The method 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 method of preparing a fluid supply assembly for use with a fluid supply applicator comprising:

providing 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, wherein the sealing portion extends upward from the outside or downward from the outside of the lid portion;

a reusable cup holder 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 reusable lid holder having a complementary connecting surface; and

a conduit having an opening therethrough, wherein the opening in the conduit has a first portion ending in a ridge, the first portion having a length less than a length of the fitting of the disposable lid;

placing the disposable cup in the reusable cup holder;

filling the disposable cup with fluid;

placing the disposable lid on the disposable cup, the sealing portion of the disposable lid fitting into the open outlet end of the disposable cup, the sealing portion contacting the sidewall forming the seal with the sidewall, the seal having an area;

attaching the reusable outer lid to the reusable cup holder, the fitting of the disposable lid being inside of the fitting of the reusable outer lid; and

attaching the conduit to the fitting of the reusable outer lid, the ridge of the conduit engaging the fitting of the disposable lid and deflecting the disposable lid downward, forcing the sealing portion outward against the sidewall thereby increasing the area of the seal.

12. The method of claim 11 wherein the disposable cup further comprises a flange extending outward from the sidewall at the open outlet end.

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

14. The method 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 method of claim 11 wherein the disposable cup is made of an antistatic material.

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

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

18. The method 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.
