Abstract
An assembly for making accurate mixtures of liquid components and feeding that liquid mixture to the inlet port of a sprayer. The assembly includes a container of stiff polymeric material comprising a side wall with a frusto conical inner surface, and a bottom wall at the bottom end of the side wall opposite a top end of the side wall that defines an opening into a cavity in the container. A flexible liner positioned within the cavity in the container has an outer surface corresponding in shape to the inner surface of the container, an inner surface defining a cavity in the liner, and an annular lip along the top end of the side wall defining an opening into the cavity in the liner. An indicating sheet of resiliently flexible polymeric material is positioned between the side wall of the container and the flexible liner, conforms in shape to the inner surface of the container, and bears indicia that indicate the levels to which a plurality of different component liquids can be sequentially poured into the cavity in the flexible liner to achieve a predetermined ratio between the liquids.
