Closure

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 ).

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.
