Capsule with structure for containing and releasing a product

Abstract

A closure capsule for closing a container, comprising: —a support (2) for a first product, said support (2) being applicable to a container and comprising a frangible bottom (20); —a cutter (3) comprising a drum (31) having at a first end (33), a cutting edge (30) to be positioned opposite the frangible bottom (20); said drum (31) forming or contributing to forming a concavity (32) which extends starting from said first end (33). The capsule (1) assumes at least a first and a second configuration. In the first configuration the frangible bottom (20) is intact and at least said frangible bottom (20) and said concavity (32) form in combination a chamber (200) adapted to contain the first product. In the second configuration said frangible bottom (20) is open to allow a mixing of the first product with a product present in the container (10). At least a part of the cutter (3) is defined at least by: —a matrix (41) made of a plastic material; —particles (42) absorbing humidity dispersed within the matrix (41); —a surface coating (43) that acts as a barrier to the passage of humidity, said surface coating (43) surrounding the matrix (41) made of plastic material.

1 . A closure capsule for closing a container, comprising:
 a support ( 2 ) for a first product, said support ( 2 ) being applicable to a container and comprising a frangible bottom ( 20 );   a cutter ( 3 ) comprising a drum ( 31 ) having at a first end ( 33 ), a cutting edge ( 30 ) to be positioned opposite the frangible bottom ( 20 ); said drum ( 31 ) forming or contributing to forming a concavity ( 32 ) which extends starting from said first end ( 33 );   
       the capsule ( 1 ) assuming at least a first and a second configuration; in the first configuration the frangible bottom ( 20 ) being intact and at least said frangible bottom ( 20 ) and said concavity ( 32 ) forming in combination a chamber ( 200 ) suitable to contain the first product; in the second configuration said frangible bottom ( 20 ) being open to allow the mixing of the first product with a product present in the container ( 10 ); 
       characterised in that at least a part of the cutter ( 3 ) is defined at least by:
 a matrix ( 41 ) made of a plastic material; 
 particles ( 42 ) absorbing humidity which are dispersed within the matrix ( 41 ); 
 a surface coating ( 43 ) that acts as a barrier to the passage of humidity, said surface coating ( 43 ) surrounding the matrix ( 41 ) made of plastic material. 
 
     
     
         2 . The capsule according to  claim 1 , characterised in that the cutter ( 3 ) comprises a base ( 34 ) from which the drum ( 31 ) extends; the base ( 34 ) and at least a part of the drum ( 31 ) are defined at least:
 by the matrix ( 41 ) made of plastic material;   by the particles ( 42 ) absorbing humidity which are dispersed within the matrix ( 41 );   by the surface coating ( 43 ) that acts as a barrier to the passage of humidity.   
     
     
         3 . The capsule according to  claim 1 , characterised in that the matrix ( 41 ) made of plastic material confers structural rigidity to the cutter ( 3 ). 
     
     
         4 . The capsule according to  claim 1 , characterised in that said matrix ( 41 ) made of plastic material in which the particles ( 42 ) that absorb humidity are dispersed affects more than 90% of the thickness of the drum ( 31 ) of the cutter ( 3 ). 
     
     
         5 . The capsule according to  claim 1 , characterised in that in the first configuration said matrix ( 41 ) made of plastic material directly delimits, at least in part, the chamber ( 200 ) and is intended to come into contact at least in part with the first product. 
     
     
         6 . The capsule according to  claim 1 , characterized in that said matrix ( 41 ) is in direct contact with said surface coating ( 43 ). 
     
     
         7 . The capsule according to  claim 1 , characterised in that said surface coating ( 43 ) defines an outer surface of the drum ( 31 ). 
     
     
         8 . The capsule according to  claim 1 , characterised in that said support ( 2 ) is a cup ( 21 ), at least a part of which is coated with an additional surface coating that acts as a barrier against the passage of humidity. 
     
     
         9 . The capsule according to  claim 1 , characterised in that said absorbent particles ( 42 ) comprise zeolite and/or calcium oxide. 
     
     
         10 . The capsule according to  claim 1 , characterised in that said surface coating ( 43 ) comprises a styrene-acrylate resin or a hydroalcoholic solution with an inorganic base.
