Abstract
A flexible, disposable cup for use in a fluid supply assembly. The disposable cup is made of an antistatic material whereby chargeable particles in a coating mixture do not stick to the disposable cup so that uniformity of the coating mixture is maintained while it is dispensed. A method of maintaining the uniformity of a coating mixture during dispensing is also described.
Claims27
A fluid supply assembly comprising a reusable plastic cup holder, a lid having an opening therein, and a flexible, disposable cup positioned 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 being see through, the disposable cup collapsing as the fluid is dispensed, the lid covering the open outlet end of the disposable cup, the disposable cup comprising a polymeric material containing an antistatic additive, the antistatic additive preventing chargeable particles in a coating mixture from sticking to the disposable cup so that uniformity of the coating mixture is maintained while it is dispensed.
A method of maintaining uniformity of a coating mixture during dispensing comprising:
- providing a reusable plastic cup holder and a lid having an opening therein;
- 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 an antistatic additive, the antistatic additive preventing chargeable particles in a coating mixture from sticking to the disposable cup, the disposable cup being see through;
- filling the disposable cup with a coating mixture containing chargeable particles;
- placing the disposable cup in the reusable cup holder;
- covering the open outlet end of the disposable cup with the 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.
A fluid supply assembly comprising a reusable plastic cup holder and a lid having an opening therein, the reusable cup holder mating with the lid, and a flexible, disposable cup positioned in the reusable cup holder, whereby the disposable cup is sealed within the reusable cup holder and the lid, the disposable cup comprising a side wall, an open outlet end, and a closed bottom defining an interior, a flange extending outward from an edge of the outlet end of the disposable cup, wherein the outlet end defines an axis, and the flange extends downward from the axis of the outlet end at an angle in a range of from about 10° to about 70°, the disposable cup being see through, the disposable cup collapsing as the fluid is dispensed, the disposable cup comprising an antistatic material so that chargeable particles in a coating mixture do not stick to the disposable cup so that uniformity of the coating mixture is maintained while it is dispensed.
A paint supply assembly comprising a reusable plastic cup holder, a lid having an opening therein, and a flexible, disposable cup positioned 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 collapsing as the paint is dispensed, the lid covering the open outlet end of the disposable cup, the disposable cup comprising a polymeric material containing an antistatic-and-see-through amount of an antistatic additive 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.
