What is claimed is: 1. An adapter for connecting a fluid supply assembly to a fluid applicator comprising: an adapter having a first end and a second end, and a bore between the first end and the second end, the first end having a connecting surface adapted to mate with a complementary connecting surface on the fluid applicator, the second end having a portion having a first shape and a portion having a second shape, the portion having the first shape being adapted to pass by a tab in an opening in the fluid supply assembly, so that the second end can be inserted into the opening, and the portion having the second shape being adapted so that it cannot pass by the tab, the second end having a height so that the second end fits under the tab in the opening, whereby when the adapter is rotated, the portion having the second shape is retained under the tab so that the adapter is locked to the fluid supply assembly. 2. The adapter of claim 1 wherein the portion having the first shape is flat, and the portion having the second shape is curved. 3. The adapter of claim 2 wherein there are two opposing flat portions and two opposing curved portions. 4. The adapter of claim 1 wherein the first end is generally cylindrical. 5. The adapter of claim 4 wherein the portion having the second shape is curved and wherein a diameter of the first end is smaller than a diameter of the curved portion of the second end. 6. The adapter of claim 1 wherein there are at least two portions having the first shape. 7. The adapter of claim 1 wherein there are at least two portions having the second shape. 8. The adapter of claim 1 wherein the connecting surface and complementary connecting surface are selected from threads, lugs and grooves, tapered connections, bayonet connections, or snap connections. 9. The adapter of claim 1 wherein the fluid supply assembly includes an outer lid having a generally cylindrical fitting, the opening in the fluid supply assembly being an opening in the fitting, the tab located at an upper end of the fitting. 10. The adapter of claim 9 wherein there is a horizontal stop at a lower end of the fitting. 11. The adapter of claim 9 wherein the fluid supply assembly further comprises a disposable lid having an integral generally cylindrical fitting with an opening therethrough, the fitting of the disposable lid adapted to fit inside the bore of the adapter when the adapter is locked to the outer lid, the opening of the disposable lid being in fluid communication with the bore of the adapter. 12. The adapter assembly of claim 1 wherein the adapter is made of metal. 13. The adapter assembly of claim 9 wherein the outer lid is made of plastic. 14. The adapter assembly of claim 9 wherein the fitting is generally cylindrical. 15. The adapter assembly of claim 1 further comprising a filter placed in the bore of the adapter. 16. The adapter assembly of claim 9 wherein the fitting has a vertical stop in the opening. 17. The adapter assembly of claim 16 wherein the vertical stop extends from the tab to a horizontal stop at a lower end of the fitting. 18. An adapter for connecting a fluid supply assembly to a fluid applicator comprising: an adapter having a first end and a second end, and a bore between the first end and the second end, the first end having a connecting surface adapted to mate with a complementary connecting surface on the fluid applicator, the second end having a portion having a first shape and a portion having a second shape, the portion having the first shape being adapted to pass by a tab in an opening in the fluid supply assembly, so that the second end can be inserted into the opening, and the portion having the second shape being adapted so that it cannot pass by the tab, the second end having a height so that the second end fits under the tab in the opening, whereby when the adapter is rotated, the portion having the second shape is retained under the tab so that the adapter is locked to the fluid supply assembly; and a filter in the bore of the adapter. 19. A method of connecting a fluid supply assembly to a fluid applicator comprising: providing an adapter having a first end and a second end, and a bore between the first end and the second end, the first end having a connecting surface adapted to mate with a complementary connecting surface on the fluid applicator, the second end having a portion having a first shape and a portion having a second shape, the portion having the first shape being adapted to pass by a tab in an opening in the fluid supply assembly, so that the second end can be inserted into the opening, and the portion having the second shape being adapted so that it cannot pass by the tab, the second end having a height so that the second end fits under the tab in the opening, whereby when the adapter is rotated, the portion having the second shape is retained under the tab so that the adapter is locked to the fluid supply assembly; connecting the first end of the adapter to the fluid applicator; matching the portion having the first shape with the tab in the opening and inserting the second end of the adapter into the opening in the fluid supply assembly; and rotating the second end of the adapter in the opening so that the portion having the second shape is retained under the tab thereby locking the adapter to the fluid supply assembly. 20. The method of claim 19 wherein the fluid supply assembly includes an outer lid having a generally cylindrical fitting, the opening in the fluid supply assembly being an opening in the fitting, the tab located at an upper end of the opening of the fitting, the fitting having a vertical stop in the opening, and wherein the second end of the adapter is rotated until it engages the vertical stop. 21. The method of claim 20 further comprising: providing a disposable lid having an integral generally cylindrical fitting with an opening therethrough; and inserting the fitting of the disposable lid into the bore of the adapter.
