There is a plastic bottle containing first and second compartments for containing, respectively, the lotion and the sunscreen agent-containing liquid and having a cylindrical neck at the top thereof containing a first bore therethrough communicating with the first compartment and a second bore therethrough communicating with the second compartment. The first bore is concentrically disposed in the neck and sized for passing known quantities of the lotion with the second bore being peripherally disposed with respect to the first bore and sized to add a quantity of the sunscreen agent which will impart a pre-selected maximum SPF value to dispensed quantities of mixtures of the lotion and the sunscreen agent. A selector dial is rotatably mounted on the neck, having a central cap portion covering the neck, a central bore through a top member thereof concentrically disposed over the first bore, and a plurality of various diameter metering bores disposed peripherally through the top member concentrically disposed to pass over the second bore as the selector dial is rotated on the neck with indicia disposed for indicating the SPF value of the metering bores. A mixing chamber member is disposed over the central cap portion and has an internal mixing chamber communicating with the first and second bores and the central and metering bores on a bottom end thereof and a third bore therethrough at a top end thereof for the egress of the mixed lotion and sunscreen agent-containing liquid. |
