Abstract
A container, for dispensing two substances simultaneously, that includes a neck portion having two orifices therein, a shoulder portion connected to the neck portion, and an elongated body portion connected to the shoulder portion, the body portion including two adjacent chambers sharing a common wall wherein each chamber is in fluid communication with an orifice in the neck portion, and wherein the two chambers are formed from different materials. The size and shape of the orifices can be varied to independently adjust the rate of dispensation of each of the two substances, or to compensate for variances in viscosity between the substances. The sizes of the two chambers can be varied independently from one another. Further, the two chambers can extend beyond the width of the common wall, to promote even and predictable deformation of the chambers when pressure is applied.
