ABSTRACT:
A bottle for two-component extemporaneous products, of the type that comprises: a container for a first component, which is provided with an upper mouth; a reservoir for containing a second component, which is inserted substantially coaxially in the mouth, is open upward and has a bottom constituted by a diaphragm; a perforator, which can be inserted in the reservoir and is adapted to pierce the diaphragm in order to mix the two components; and a removable cap for closing the container in an upward region; the cap comprises a lower annular portion that is fixed to the container and an upper cylindrical portion that cooperates with the perforator and is rigidly coupled to the annular portion at an intermediate weakened region suitable to act as sealing means, a downward pressure on the cylindrical portion being adapted to disengage it from the annular portion and to make the perforator slide in the reservoir in order to pierce the underlying diaphragm.
