Abstract: A frothing device (1) is disclosed which is suited for a beverage machine. The frothing unit has an inlet (11) for a frothing medium (12) and a gas inlet (13) with an opening diameter. Furthermore, the frothing unit comprises a pumping means (14) and a tubing (15) for connecting the aforementioned components to one another. The aforementioned components form a continuous tubing system. In addition, due to the pumping action of the pumping means, a negative pressure difference with respect to the atmospheric pressure is accomplished throughout the whole tubing system.

Abstract: The system includes an appliance for personal body care, a pump and a holder. The appliance comprises a treatment device for carrying out a body-care treatment under the influence of a fluid. The fluid is held in the holder and can be pumped to an outlet opening by means of the pump. The holder includes a flexible wall, and the pump is detachable from the holder and is detachable from the appliance. This combination of measures makes it possible to adapt the dimensions of the holder to an ergonomic shape of the appliance.

Abstract: The system comprises an appliance (10) for personal body care, a pump (20) and a holder (40). The appliance (10) comprises a treatment device (11, 14, 31) for carrying out a body-care treatment under the influence of a fluid. The fluid is held in the holder (40) and can be pumped to an outlet opening 30 (32) by means of the pump (20). The system is characterized in that the holder (40) comprises a flexible wall (41), and in that the pump (20) is detachable from the holder (40) and is detachable from the appliance (10). This combination of measures makes 42 it possible to adapt the dimensions of the holder (40) to an 4 ergonomic shape of the appliance (10).
