Liquid deposit bottle with an elastically reversible deformation wall, equipped with a liquid distribution head (1) that is fixed in a sealed connection inside a neck (10) of the bottle (2), which includes a filtering device (26 ) wall semipermeable membrane partly hydrophilic in nature and partly hydrophobic in nature arranged at the interface between the interior and exterior of the liquid reservoir bottle and managing the expulsion of liquid through an external hole (22) and the inlet of air through the same orifice, as a function of a pressure differential on either side, in which, on its surface of hydrophilic nature, said membrane is selectively permeable to liquid in the presence of air and on its surface of hydrophobic nature, the said membrane is selectively permeable to air in the presence of the liquid, characterized in that on its hydrophilic surface, the membrane is made in the form of tubular filters (30； 130) for expulsion of liquid that extend longitudinally inside the bottle from a perforated mounting plate (28) (28； 128) transverse in said distribution head, through which the tubular filters (30； 130) flow outwards, and because, on its hydrophobic surface, said membrane is made in the form of one or more tubular filters (32； 132) and arranged in the vicinity of said perforated plate (28； 128 ) to serve for the entry of air into the bottle in compensation of the expelled liquid.Frasco depósito de líquido de pared de deformación elásticamente reversible, equipado con un cabezal de distribución de líquido (1) que se fija en unión estanca en el interior de un cuello (10) del frasco (2), que comprende un dispositivo filtrante (26) de pared en membrana semipermeable en parte de naturaleza hidrófila y en parte de naturaleza hidrófoba dispuesta en la interfaz entre el interior y el exterior del frasco depósito de líquido y que gestiona la expulsión de líquido por un orificio exterior (22) y la entrada de aire por el mismo orificio, en función de un diferen
