The present invention provides a combined device for packaging and dispensing liquids, the device comprising: a container containing a supply of liquid; and a refillable unit removably placed on the container, the refillable unit comprising: a body and a relative body-moving pistons cooperating to form a variable-volume storage chamber for holding a liquid in fluid communication with the container for filling therefrom when the refillable unit is placed on the container; and a pump, The pump is capable of drawing liquid from the container when the refillable unit is placed on the container and from the storage chamber when the refillable unit is separated from the container, the pump having a pump chamber different from the storage chamber.
Description
technical field The invention relates to a combination device for encapsulating and dispensing liquids, in particular cosmetics, including care products. Background technique In the meaning of the present invention, the term "cosmetics" is used to denote cosmetic products, as defined by Directive 93 / 35 / EEC of 14 June 1993 as amended by Directive 76 / 768 / EEC. Patent application FR 2 773 443 discloses a refillable atomizing sprayer comprising a body forming a chamber for containing a liquid. The sprayer also includes a piston that is slidably received in the body and can be depressed to reduce the volume of the chamber and dispense the liquid. The amount of substance dispensed depends on the length of the piston's depression stroke, with the chamber being completely emptied when the piston is depressed its full stroke. It is difficult for such nebulizers to dispense the precise amount of liquid corresponding to the largest volume fraction of the chamber. Patent application...
