Abstract (en)

[origin: WO2019215417A1] The invention relates to a reservoir (100) for a liquid, comprising: at least one inner chamber (104) and an upper mouth (102), each chamber being provided with an inner opening; and a stopper (130) which closes the upper mouth, the stopper having a substantially flat, elastically deformable flexible part (133). In modes of embodiment, the deformation resistance of the flexible part towards the inside of the reservoir tapers off during the deformation of said part. In modes of embodiment, the reservoir comprises a main chamber comprising a quantity of liquid and comprising a lower opening for distribution of the liquid, and a secondary chamber positioned between the stopper and the main chamber, the secondary chamber being separated from the main chamber by a tight separating wall provided with the inner opening of the secondary chamber, which fluidically connects the main chamber and the secondary chamber.
