Abstract

A closure including: a reservoir (4) which in turn includes a rupturable bottom (40), the reservoir (4) being applicable to a mouth (60) of a container (6) destined to contain a first product; a cutter (5), positionable in front of the rupturable bottom (40). The closure (10) takes on at least a first and a second configuration; in the first configuration, the rupturable bottom (40) being intact and at least the reservoir (4) and the cutter (5) identifying, in combination, a first chamber (2) suitable for containing a second product; in the second configuration the rupturable bottom (40) being open such as to enable a mixing of the first and the second product. The closure (1) includes moisture absorbing apparatus (7) which in the first configuration of the capsule (1) is in contact with an inside of the first chamber (2).

Claims

1. A closure comprising:

a reservoir (4) in turn comprising a rupturable bottom (40), said reservoir (4) being applicable to a mouth (60) of a container (6) destined to contain a first product;

a cutter (5), positionable in front of the rupturable bottom (40) for opening said rupturable bottom (40);

said closure (10) taking on at least a first and a second configuration;

in the first configuration, the rupturable bottom (40) being intact and at least the reservoir (4) and the cutter (5) identifying, in combination, a first chamber (2) suitable for containing a second product;

in the second configuration said rupturable bottom (40) being open such as to enable a mixing of the first and the second product;

moisture absorbing means (7) which in the first configuration of the closure (1) are in contact with an inside of the first chamber (2);

the cutter (5) comprising a hollow body (50) in turn comprising a cutter edge (51) and a stem;

said cutter edge (51) being fashioned at an end of the stem and in the first configuration being in front of said rupturable bottom (40);

said closure being characterised in that the moisture absorbing means (7) at least partly delimit an internal cavity (8) inside the hollow body (50) and the stem and at least partly clad an internal surface (53) of said hollow body, the cavity (8) in the first configuration being a part of the first chamber (2);

said absorbing means (7) are shaped;

as a hollow sleeve;

or

as a hollow beaker and clad an internal bottom and an internal wall of the hollow body (50).

2. A capsule according to claim 1, characterised in that the reservoir (4) comprises a guide surface of the cutter (5) during the displacement thereof which determines the passage from the first to the second configuration;

said internal surface (53) is surrounded by an external surface (54) of the cutter (5), said external surface (54) being in contact with said guide surface (42) at least in the first and/or in the second configuration.

3. The closure according to claim 1, characterised in that said moisture absorbing means (7) develop over at least two thirds of a length of said hollow body (50).

4. The closure according to claim 1, characterised in that said moisture absorbing means (7) are co-moulded with said hollow body (50).

5. The closure according to claim 1, characterised in that in the first configuration, in proximity of said cutter edge (51), the internal cavity (8) is in fluid communication with a portion of the first chamber (2) external of the hollow body (50).

6. A package comprising:

a closure (10) according to claim 1;

a container (6) comprising a mouth (60) to which said closure (10) is directly or indirectly applied, said container (6) identifying a second chamber (3) suitable for containing the first product;

said package (1) assuming at least an initial configuration and an operative configuration;

in the initial configuration said closure (10) being in the first configuration and the first and the second chamber (2, 3) being fluid-dynamically separate;

in the operative configuration the closure (10) being in the second configuration and the first and the second chamber (2, 3) being in reciprocal fluid communication such as to enable a mixing of the first and the second product.

7. The package according to claim 6, characterised in that it comprises a hood (9) which in the initial configuration of the package (1) is connected to the container (6) and protects the reservoir (4) from tampering, said hood (9) comprising a tamper-proof band (90) which must be removed in order for the hood (9) to be removed.
