COMPACT CONTAINER FOR FLUID Russian patent published in 2016 - IPC A45D34/00 A45D34/02 B05B11/00 

FIELD: packaging industry.

SUBSTANCE: this invention is related to system of containers for liquids, such as perfume-spray. Self-contained dispenser for fluids comprises rigid container in form of bowl or tray with open surface having hole for filling, that remains closed by valve until dispenser is not connected to feed container, and dispensing hole for spraying. Said holes are spaced from each other. Open surface of bowl is coated with deformable elastic membrane to form closed dosing cavity adjacent to hole for filling. Volume of this cavity decreases when membrane deforms inward in order to empty cavity. Holes for filling and dispensing are such that, If communicated with feed container via opening for filling initially empty cavity, when membrane subsequently returns to position in previous form, it surpasses liquid from feeding container into cavity. Elasticity of membrane at deformation creates negative pressure sufficient to suck fluid from feeding container when fluid inside feeding container is not sealed. Dispenser is configured to be repeatedly filled or emptied simply by connection of dispensing unit to feed container. Dispenser is made with possibility of detachment from feed container for use.

EFFECT: expanded operating performances of device, self-sufficiency, and possibility of automatic filling.
