Abstract: A disposable shaker has an upper cover part having a multi-compartment with compartments closed by a membrane and containing components of the desired cocktail and having a lower cup part rotatingly associated to the cover part with teeth for tearing the membrane. The separation walls forming the compartments are obtained as substantially U-shaped hollow walls, opening outwards and having the transverse side of the U-shape forming the surface for fixing the membrane. Along the longitudinal axis of the multi-compartment the separation walls are joined in a single piece with an axial duct which is extended along the multi-compartment. Also provided for is an element suitable to guarantee proper positioning between the cover part and the cup part in the assembled position, and elastic locking elements preventing the shaker from opening after preparing the cocktail. The shaker may have an “overturned arrangement” of the internal structures of the cover and cup.

Abstract: A disposable shaker (1) made of synthetic material having a cup-like cover (3) and a cup-like base (2) which can be removably connected together and have or form the one or the other (2; 3) a container with a plurality of bins (4) which contain the ingredients for a desired cocktail and are closed by a membrane (6) which is tearable by means of tearing teeth (7) in one-piece with said cover (3) or base (2) inside thereof. In a preferred embodiment the shaker (1) is provided with unambiguous guiding manipulation means (20) for the membrane tearing stroke and shaker opening stroke after the mixing or shaking phase for the cocktail preparation.
