LIQUID FEEDING APPARATUS Russian patent published in 2007 - IPC B05B9/03 

FIELD: liquid feeding equipment for feeding liquids and directing mixtures of liquid components to be sprayed onto liquid spraying devices, for example gun-type sprayers, to indicating marks of such devices used for measuring of predetermined concentrations of components for liquid mixture to be sprayed by means of such devices.

SUBSTANCE: apparatus has container made from rigid polymer material and provided with side wall having internal surface made in the form of truncated cone, and bottom arranged at lower edge of side wall, opposite upper edge of side wall defining passage leading into container cavity. Flexible insert located within container cavity has external surface having shape conforming to that of internal surface of container, and annular bead extending along upper edge of side wall defining passage into insert cavity. Tamperproof tape made from flexible resilient polymer material is located between container side wall and flexible insert, and conforms in its shape with that of internal surface of container. Tamperproof tape is provided with marks indicating levels to which number of kinds of liquids may be poured into cavity of flexible insert until predetermined liquid ratio is achieved. Apparatus of such construction allows mixtures with precise ratio of components to be prepared and fed to inlet opening of sprayer.

EFFECT: increased efficiency by selecting proper tamperproof tapes from set of tamperproof tapes, which tapes being necessary for preparing the majority of mixtures of liquid components delivered by main manufacturers, and reduced tamperproof manufacture costs.
