1. A closure capsule for closing a container, comprising:
a cap ( 2 ) that can be associated with a container and comprising a frangible mouth ( 20 );
a cutter ( 3 ) comprising a cutting edge ( 30 ) designed to open said frangible mouth ( 20 ); at least said cap ( 2 ) and said cutter ( 3 ) in combination defining a reservoir ( 8 ) for containing a substance to be dropped into the container when the frangible mouth ( 20 ) is opened;
a covering ( 4 ) that protects the cap ( 2 ) and the cutter ( 3 ); said covering ( 4 ) being separate from the cutter ( 3 ) and, in turn, comprising:
i) a lateral wall ( 40 ) that encloses a zone ( 402 ) for at least partially housing the cutter ( 3 );
ii) a base ( 41 ) from which said lateral wall ( 40 ) extends;
a first and a second portion ( 51 , 52 ) respectively incorporated in the covering ( 4 ) and in the cutter ( 3 ) for transmitting an opening torque from the covering to the cutter for opening the frangible mouth ( 20 ); said first portion ( 51 ) being incorporated in the base ( 41 ); characterized in that the first and the second portion ( 51 , 52 ), when enmeshed, enables a solidly rotational-translational movement of the covering ( 4 ) and of the cutter ( 3 ).
2. The capsule according to claim 1 , characterized in that said first and second portions ( 51 , 52 ) are movable between a first position, in which they are engaged to each other so as to enable transmission of the opening torque, from the covering ( 4 ) to the cutter ( 3 ), for opening the frangible mouth ( 20 ), and a position in which they are set apart from each other and in which the transmitting means ( 5 ) is disengaged.
3. The capsule according to claim 1 , characterized in that the transmitting means ( 5 ) comprises a first set ( 510 ) of teeth afforded in said first portion ( 51 ) and a second set ( 520 ) of teeth afforded in said second portion ( 52 ).
4. The capsule according to claim 1 , characterized in that the cutting edge ( 30 ) defines a concavity ( 31 ), which, upon completion of the opening of the frangible mouth ( 20 ), partly receives a small disc that projects in a cantilever fashion and that results from the partial opening of the frangible mouth ( 20 ).
5. The capsule according to claim 1 , characterized in that the covering ( 4 ) comprises a thread ( 401 ) having its own pitch and that is suitable for connecting the covering ( 4 ) to a container; the height of the cutting edge ( 30 ) being lower with respect to the pitch of the thread ( 401 ) of the covering ( 4 ).
6. The capsule according to claim 3 , characterized in that the covering ( 4 ) comprises a thread ( 401 ) having its own pitch and that is suitable for connecting the covering ( 4 ) to a container; the height of the cutting edge ( 30 ) being lower with respect to the pitch of the thread ( 401 ) of the covering ( 4 ).
7. The capsule according to claim 1 , characterized in that the covering ( 4 ) comprises an intactness band ( 400 ) that is made of a first plastic material which is more deformable with respect to a second plastic material of which said cutter ( 3 ) is made.
8. The capsule according to claim 3 , characterized in that the covering ( 4 ) comprises a thread ( 401 ) having its own pitch and that is suitable for connecting the covering ( 4 ) to a container; the height of the cutting edge ( 30 ) being lower with respect to the pitch of the thread ( 401 ) of the covering ( 4 ).
9. The capsule according to claim 6 , wherein the height of the second set ( 520 ) of teeth is higher with respect to the pitch of the thread ( 401 ).
10. A system comprising:
a container ( 10 ) comprising a mouthpiece ( 11 );
a capsule according to claim 1 , said cap ( 2 ) of said capsule ( 1 ) being applied to the mouthpiece ( 11 ) of the container ( 10 ).
11. The system according to claim 10 , characterized in that said cap ( 2 ) comprises a plurality of anti-rotation teeth ( 12 ) that interlock in respective seats ( 110 ) afforded in said mouthpiece ( 11 ).
12. A method for opening a container, characterized in that it comprises the steps of:
providing a container having a mouthpiece occluded by a capsule according to claim 1 ;
screwing the covering ( 4 ) on the container, drawing the cutter ( 3 ) into rotational-translational movement so as to open the frangible mouth ( 20 ) and drop the substance present in the reservoir ( 8 ) into the container;
unscrewing the covering ( 4 ) from the container ( 10 ), the step of unscrewing the covering ( 4 ) from the container ( 10 ), thus drawing and thereby bringing about the extraction of the cutter ( 3 ) and the cap ( 2 ) from the container ( 10 ).
