What is claimed is: 1. A disposable liner comprising at least one side wall defining a volume for containing material having chargeable particles therein, the disposable liner being see-through wherein the liner comprises a polymeric material containing conductive nanofibers preventing chargeable particles in a coating mixture from sticking to the disposable liner so that uniformity of the coating mixture is maintained while it is dispensed. 2. The disposable liner of claim 1 wherein the disposable liner comprises a flexible, disposable cup, the disposable cup comprising a side wall, an open outlet end, and a closed bottom defining an interior, the side wall extending between the outlet and the bottom, wherein the disposable cup stands on the bottom, and wherein the side wall collapses when fluid is withdrawn from the disposable cup. 3. The disposable liner of claim 2 wherein a flange extends outward from an edge of the outlet end of the disposable cup. 4. The disposable liner of claim 3 wherein the flange extends downward from the outlet end at an angle in a range of from about 10° to about 70°. 5. The disposable liner of claim 3 wherein the flange of the disposable cup further comprises a removal tab. 6. The disposable liner of claim 2 wherein the disposable cup has indicia for measuring fluids on the side wall. 7. The disposable liner of claim 2 wherein the side wall is generally cylindrical. 8. The disposable liner of claim 2 wherein the side wall is generally elliptical. 9. The disposable liner of claim 2 wherein the side wall has a first portion adjacent to the outlet end, the side wall has a second portion adjacent to the bottom, the side wall has a third portion between the first and second portions, the first and second portions having a thickness greater than a thickness of the third portion. 10. The disposable liner 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. The disposable liner of claim 9 wherein the first and second portions each cover about one fourth of the side wall. 12. The disposable liner of claim 2 wherein the coating mixture is a paint mixture and the chargeable particles are metallic particles, and wherein uniformity of the coating mixture is uniformity of a color of the paint mixture. 13. The disposable liner of claim 1 wherein the conductive nanofibers comprise carbon nanofibers. 14. The disposable liner of claim 1 wherein the polymeric material is selected from polyethylene, or polypropylene. 15. The disposable liner of claim 1 wherein the disposable liner comprises a flexible bag comprising a side wall defining the volume for containing the material having chargeable particles therein, an opening adjacent one end and a sealed zipper closure adjacent the opposite end. 16. A method of maintaining uniformity of a coating mixture during dispensing comprising: providing a reusable cup holder and an outer lid having an opening therein, the reusable cup holder adapted to mate with the outer lid; providing a disposable cup adapted to fit in the reusable cup holder, the disposable cup comprising a side wall, an open outlet end, and a closed bottom defining an interior, the disposable cup comprising a polymeric material containing antistatic conductive nanofibers preventing the chargeable particles in the coating mixture from sticking to the disposable cup so that uniformity of the coating mixture is maintained while it is dispensed, the disposable cup being see through; filling the disposable cup with a coating mixture containing chargeable particles; placing the disposable cup in reusable cup holder; attaching the outer lid to the reusable cup holder, sealing the disposable cup within the reusable cup holder and the outer lid; connecting the opening in the lid to a spray gun; and dispensing the coating mixture, the disposable cup collapsing as the coating mixture is dispensed, whereby the chargeable particles in the coating mixture do not stick to the disposable cup so that uniformity of the coating mixture is maintained while it is dispensed. 17. The method of claim 16 wherein the coating mixture is a paint mixture and the chargeable particles are metallic particles, and wherein uniformity of the coating mixture is uniformity of a color of the paint mixture. 18. A flexible disposable cup comprising a side wall, an open outlet end, and a closed bottom defining an interior, the disposable cup collapsing as paint is dispersed, the disposable cup being see-through, the disposable cup comprising a polymeric material containing an antistatic and see-through amount of conductive nanofibers to prevent metallic particles in paint from sticking to the disposable cup so that uniformity of the color of the paint is maintained while it is dispensed and to provide the see-through disposable cup.
