Abstract: An apparatus for personal hygiene which includes a reservoir for containing liquid to be applied to selected parts of the body is provided with a dispenser containing a dentifrice to be dispensed therefrom upon demand. The dispenser is adapted to be housed in the bottom part of the casing of the apparatus. The dispenser is provided with a dentifrice container closed at the bottom by a flexible membrane and with an intermediate wall located above this membrane defining upper and lower container compartments. The intermediate wall includes an opening which permits communication between the two compartments. A closure finger attached to the membrane opposite the opening in the intermediate wall is adapted to be shifted between positions at which it is spaced from the opening and also disposed within the opening. In this manner, pressure applied to the membrane causes the closure finger to enter the opening and permits a measured quantity of the dentifrice to be taken off from the lower compartment.
