Abstract
A reservoir assembly (40) comprises a container (4), a support assembly (42) on which the container (4) is mounted and fixed and a rotary electric vibrator device (44) coupled to the support assembly (42). The container holds a shear thinning additive for a plastics material. The reservoir assembly is arranged so that on operation of the device (44), an appropriate frequency and amplitude of vibration is applied to the container (4) and, therefore, its contents. As a result, a liquid dispersion in the container is shear thinned and recovery of dispersion from the container is increased.
