The packaging allows manual or automatic expulsion of liquids or pastes without the use of air or gases. It is composed of one or more bellows (1) which can be compressed under the effect of a force. The bellows are closed at their ends by a rigid plate (2). The packaging also has, under its base, two tabs or overhanging stabilisers (3) which maintain the packaging in equilibrium after being compressed, The compression can be effected either manually or automatically with the aid of compressing parts such as elastic, springs, metal tongues etc. In the packaging upper part is an outlet hole extended by a dispensing cap composed of two containers fitting and sealed into each other. These containers each have two outlet orifices. A dispensing mouth extends the upper container. A spring returns the retractable part of the dispensing cap into its initial position.
