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.

Claims

1. 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 said mouth, is open upward and has a bottom constituted by a diaphragm;

a perforator, which can be inserted in said reservoir and is suitable to pierce said diaphragm in order to mix the two components; and

a removable cap for closing the container in an upward region, characterized in that said cap comprises a lower annular portion that is fixed to said container and an upper cylindrical portion that is suitable to cooperate with said perforator and is rigidly coupled to said annular portion at an intermediate weakened region suitable to act as sealing means, a downward pressure on said cylindrical portion being suitable to disengage it from said annular portion and to make said perforator slide in said reservoir in order to pierce the underlying diaphragm.

2. The bottle according to claim 1, characterized in that said annular portion comprises means for interlocking coupling with the outer walls of said container proximate to said mouth.

3. The bottle according to claim 1, characterized in that said cylindrical portion is constituted by a hollow cylindrical body, in which the upper end is closed and the lower end is open and protrudes into said annular portion.

4. The bottle according to claim 3, characterized in that said perforator is constituted by a tubular body that is provided with a lower piercing profile and with an upper abutment collar, and in that said cylindrical portion has a lower end that is partially inserted in said body and is provided with an external circumferential expansion that is rigidly coupled to said annular portion at said weakened intermediate region constituted by a circumferential prefracture line, downward pressure being suitable to break said line and cause the descent, in succession, of said cylindrical portion until said expansion abuts against said collar and of said perforator until said collar abuts against a corresponding stroke limiting surface formed inside the underlying reservoir.

5. The bottle according to one or more of the preceding claims, characterized in that said reservoir comprises a seat for the interlocking insertion of said collar that is formed at said stroke limiting surface and is suitable to lock the perforator once piercing has occurred, said cylindrical portion being individually removable and reinsertable in the perforator anchored to the reservoir in order to subsequently open and close the container.

6. The bottle according to claims 1 and 2, characterized in that said cylindrical portion and said perforator are formed monolithically.

7. The bottle according to claim 6, characterized in that said cylindrical portion is constituted by an elongated hollow cylindrical body whose upper end is closed and whose lower end is open and protrudes into said annular portion so as to enter said reservoir and has a lower rim constituted by a piercing profile, downward pressure being suitable to disengage the cylindrical portion from the annular portion and make it slide inside the reservoir in order to pierce the diaphragm.

8. The bottle according to claims 6 and 7, characterized in that the disengaged cylindrical portion can be removed and reinserted in said reservoir in order to subsequently open and close the container.

9. The bottle according to claims 6 to 8, characterized in that said cylindrical portion is provided with a plurality of reference notches for the level of product, the removed cylindrical portion being suitable to act as a measurer for the prepared product.
