The bottle or the like has a partially cylindrical inside Neck or mouthpiece (12) of a given internal diameter D (Pig. 6) and has an external thread (H). The final one The edge should be as flat or even as possible. The actual facility comprises the parts in combination (18) and (20), which form the auxiliary container for the storage of one component of the product, that of another Component (generally consisting of a solution or Dispersion liquid), which in turn is contained in the main container realized by the bottle (10), should be kept physically hermetically separated.

The part (18) comprises a small transparent container body (22) which has a bottom (24) which can be opened or cut off circumferentially as a result he (at 26) at its connection zone with said container body (22)! Is weakened. Said container body (22) is provided at the top with a flange (28), the lower annular surface with elevations or ribs (30), (Fig. 2) for resting on the edge (16) of the mouthpiece, equipped can be or is designed flat as indicated at 30 'in FIG. 3. -.

Said flange (28) has an annular groove (32), ■ which in turn is used for sliding, with the part (20) surrounding sealing inner elevation (34). Furthermore is the upper fraction - {22a} 'of the small transparent body (22)
