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. ## Claims ### Claim 1 A disposable shaker comprising: a cup-like base part (2); and a cup-like cover part (3) which are removably joinable together with an axial snap engagement or with a rotatable engagement, wherein one of said cover (3) or base (2) houses or forms a multibin container (9) which is capable of being tightly closed by means of a membrane (6) and serves for housing the single ingredients of a cocktail or liquid mixture to be prepared, wherein tearing teeth (7) for tearing said membrane (6) during said engagement between said cover part (3) and said base part (2) are provided, wherein said membrane (6) closing said multibin container (3; 2) is fixed to the latter, and in that said tearing teeth (7) for tearing said membrane (6) are formed in one-piece with in said base part (2) or cover part (3) and having tearing points near said membrane (6) in the closed or assembled position of said shaker (1) so that at least one of an axial and rotational mutual translation movement between said cover (3) and base (2) causes a penetration of said tearing teeth (7) into said membrane (6) with a consequent known tearing of the latter (6) and transfer of the cocktail ingredients, which are directly or indirectly contained in the bins (4) of said cover (3) or base (2), into the respective other mixing part (2; 3) of said shaker (1) for the mixing or shaking of said ingredients into said shaker, further comprising an unambiguous manipulation means (20) for the membrane (6) perforation and tearing movements and the opening movements of the shaker (1) after the shaking or agitation manipulation, wherein said unambiguous manipulation means (20) for the membrane (6) perforation and tearing movements and the opening movements of the shaker (1) comprise: 1) in the base part (2): a positioning projection (21) near each tearing tooth (7) above the latter, 2) in the cover part (3), provided with said bins (4) delimited by an external piston-like cylindrical wall (22) having an upper annular closure flange (23) and a lower annular flange (24) on which latter said membrane (6) is sealed: an external annular crown (25), formed by a number of annular segments (26) which are separated at a distance from each other, which number of segments (26) corresponds to the number of tearing teeth (7), wherein between the opposite segment ends (26A) are provided: an axial strip-like stop (27) substantially placed in the middle and extending between the upper flange (23) and the lower side (26B) of said annular segments (26), as well as at one side of said axial strip-like stop (27), a positioning wing (28) which radially projects from said cylindrical wall (22) for an amount which is smaller then the radial thickness of said segments (26), which positioning wing (28) may swing about the horizontal plane under a pushing action, and at the other side of said axial strip-like stop (27), a free transit passage (29) for a positioning projection (21) during the opening of the shaker (1). ### Claim 2 (depends on 1) The shaker according to claim 1, further comprises at least one tearing tooth (7) for each bin (4) of said cover (3) or base (2). ### Claim 3 (depends on 1) The shaker according to claim 1, wherein said tearing teeth (7) are formed on the lateral internal wall or on the bottom (12) of said base (2) or cover (3). ### Claim 4 (depends on 1) The shaker according to claim 1, wherein a middle axial column (12) of said cover (3) is provided an axial hole (11) and also in said membrane (6) is provided a middle axial hole through which holes a straw (10) may be conducted and inserted into said shaker (1). ### Claim 5 (depends on 1) The shaker according to claim 1, wherein said cup-like base (2) is formed like a tea-cup or espresso-cup and is provided with a projecting handgrip (13). ### Claim 6 (depends on 1) The shaker according to claim 1, wherein the base (2) is like a container having several bins (4) and said tearing teeth (7) are provided in said cover (3), wherein said shaker (1) has an enlarged bottle-like conformation and at the top of said cover (3) is provided a plug (15) which may contain an integrator component which is manually releasable by the user. ### Claim 7 (depends on 6) The shaker according to claim 6, the shaker has a conformation of a flat bottle. ### Claim 8 (depends on 6) The shaker according to claim 6, wherein said bins (4) said ingredients are contained in cartridges (17), wherein said cartridges are made of tearable synthetic materials. ### Claim 9 (depends on 1) The shaker according to claim 1, with a cover (3) and a base (2) having coupling means which are movable by means of a thread, rotation or pushing engagement, further comprising one of a guarantee tongue and a narrow band which is obtained from the shaker packaging or covering film and partially covers both said cover (3) and said base (2). ### Claim 10 (depends on 1) The shaker according to claim 1, wherein the rotatable engagement is a thread engagement. ### Claim 11 A disposable shaker comprising: a cup-like base part (2); and a cup-like cover part (3) which are removably joinable together with an axial snap engagement or with a rotatable engagement, wherein one of said cover (3) or base (2) houses or forms a multibin container (9) which may be is capable of being tightly closed by means of a membrane (6) and serves for housing the single ingredients of a cocktail or liquid mixture to be prepared, wherein tearing teeth (7) for tearing said membrane (6) during said engagement between said cover part (3) and said base part (2) are provided, wherein said membrane (6) closing said multibin container (3;
