Abstract

A safety capsule for containers, comprising: an external cap ( 2 ), provided with coupling means for the coupling thereof to the neck (C) of a container; an internal element ( 3 ), located inside the external cap ( 2 ) and configured to be associated, in a removable manner, with an opening (A) of the container; connecting means ( 4, 5 ), interposed between the external cap ( 2 ) and the internal element ( 3 ), and structured so as to leave the external cap ( 2 ) and the internal element ( 3 ) unconstrained with respect to a movement for opening or removal of the external cap ( 2 ) between a closed position and an intermediate position, and solidly constrain the external cap ( 2 ) and the internal element ( 3 ) with respect to the movement for opening or removal of the external cap ( 2 ) between the intermediate position and an opening position.

First claim

The invention claimed is:

1. A safety capsule for containers, comprising:
an external cap ( 2 );
an internal element ( 3 ), located inside the external cap ( 2 ) and configured to be associated, in a removable manner, with an opening (A) of the container;
a coupling means, configured to enable coupling of the external cap ( 2 ) or the internal element ( 3 ) to the neck (C) of the container;
connecting means ( 4 , 5 ), interposed between the external cap ( 2 ) and the internal element ( 3 ), and structured so as to leave the external cap ( 2 ) and the internal element ( 3 ) unconstrained with respect to a movement for opening or removal of the external cap ( 2 ) between a closed position and an intermediate, position, and solidly constrain the external cap ( 2 ) and the internal element ( 3 ) with respect to the movement for opening or removal of the external cap ( 2 ) between the intermediate position and an opening position;
the coupling means for coupling the external cap ( 2 ) or the internal element ( 3 ) and the neck (C) of the container provides for at least one rotation movement about a longitudinal axis (X) for the opening or the removal of the external cap ( 2 ) from the neck (C) of the container;
the connecting means ( 4 , 5 ) comprise at least a first connecting element ( 4 ), solidly constrained to the external cap ( 2 ), and at least a second connecting element ( 5 ), solidly constrained to the internal element ( 3 );
the internal element ( 3 ) comprises projecting edge ( 33 ) of a substantially annular shape and concentric with the longitudinal axis (X), for constraining the internal element to the external cap ( 2 ) with respect to movements along the longitudinal axis (X);
the first connecting element ( 4 ) comprises a small tooth ( 41 , 42 ) that projects radially from an inner surface of the external cap ( 2 ) and faces the internal element ( 3 );
the second connecting element ( 5 ) comprises a first small tooth ( 51 ) that projects downwards from an external surface of the internal element ( 3 ) and faces the external cap ( 2 );
the small tooth ( 41 , 42 ) of the first connecting element ( 4 ) projects beneath the projecting edge ( 33 ) of the internal element ( 3 ), so as to prevent the internal element from sliding off the external cap ( 2 ).

2. The capsule according to claim 1 , wherein the second connecting element ( 5 ) comprises a second small tooth ( 52 ), alongside the first small tooth ( 51 ) so as to define a shaped space to receive the first connecting element ( 4 ) in the intermediate opening or removal position.

3. The capsule according to claim 2 , wherein the second small tooth ( 52 ) has an external side, facing the opposite side that of the first small tooth ( 51 ), and shaped so as to facilitate passage over the small tooth ( 41 ) of the first connecting element ( 4 ) of the external cap ( 2 ) during the opening rotation of the external cap ( 2 ).

4. The capsule according to claim 2 , wherein the second small tooth ( 52 ) increases in thickness nearer to the first small tooth ( 51 ).

5. The capsule according to claim 2 , comprising a projecting edge ( 101 ), solidly constrained to the neck (C) of the container and structured so as to come into contact with the second small tooth ( 52 ) and to bend the second small tooth ( 52 ) outward.

6. The capsule according to claim 2 , wherein the second small tooth ( 52 ) has a cavity ( 52 C).

7. The capsule according to claim 2 , wherein the second small tooth ( 52 ) has an appendage ( 52 P) facing the first small tooth ( 51 ).

8. The capsule according to claim 2 , wherein the internal element ( 3 ) comprises a recess ( 3 A) disposed above the second small tooth ( 52 ).

9. The capsule according to claim 2 , wherein the second small tooth ( 52 ) comprises a first portion ( 52 a ) and a second portion ( 52 b ); the first portion ( 52 a ) is structured in such a way as substantially not to interact with the small tooth ( 41 ); the second portion ( 52 b ) is structured to interact with the small tooth ( 41 ) and is deformable along a circumferential direction relative to the first portion ( 52 a ).

10. The capsule according to claim 2 , wherein the first small tooth ( 51 ) and the second small tooth ( 52 ) are associated with a projecting edge ( 33 ) of the internal element ( 3 ) and project downwards.

11. The capsule according to claim 2 , comprising: an abutment element ( 1 C) that radially projects from the neck (C) of the container; a third small tooth ( 513 ), solidly constrained to the internal element ( 3 ), and structured so as to come into contact and interact with the abutment element ( 1 C).

12. The capsule according to claim 11 , wherein the external cap ( 2 ) comprises an abutment ( 43 ), which projects towards the internal element ( 3 ) from an inner surface of the external cap ( 2 ); the abutment ( 43 ) is positioned in such a way as to be superimposed on the third small tooth ( 513 ) in proximity to the intermediate position.

13. The capsule according to claim 1 , comprising: a groove ( 53 ), fashioned on an upper surface ( 31 ) of the internal element ( 3 ); a projecting element ( 410 ), which projects beneath the upper portion ( 21 ) of the external cap ( 2 ) and is configured to engage with the groove ( 53 ); the groove ( 53 ) is shaped so as to produce an axial movement between the internal element ( 3 ) and an upper portion ( 21 ) of the external cap ( 2 ) during the opening rotation.

14. The capsule according to claim 13 , wherein the groove ( 53 ) has a variable depth, decreasing or increasing in the direction of the opening rotation.

15. The capsule according to claim 1 , wherein the connecting means comprise a first small tooth ( 41 ) that projects from an inner surface of the external cap ( 2 ) and faces the internal element ( 3 ), said first small tooth ( 41 ) being structured so as to interact with the second connecting element ( 5 ) and to retain the internal element ( 3 ) inside the external cap ( 2 ), with or without a given axial clearance.

16. The capsule according to claim 15 , wherein the internal element ( 3 ) is provided with a guide section ( 515 ), which is structured so as to interact with the first small tooth ( 41 ) and to force itself between the first small tooth ( 41 ) and the upper portion ( 21 ) of the external cap ( 2 ) during a closing rotation of the external cap ( 2 ), so as to eliminate all clearance between the internal element ( 3 ) and the external cap ( 2 ) in the axial direction.

17. The capsule according to claim 1 , comprising signalling means (S), structured to take on a given configuration in the intermediate position.

18. The capsule according to claim 17 , wherein the external cap ( 2 ) has at least one transparent or semi-transparent top portion ( 21 ); the signalling means (S) comprises at least a first signal ( 71 ), which is solidly integral with the external cap ( 2 ) and visible through the top part ( 21 ) thereof, and at least a second signal ( 72 ), which is solidly constrained to the internal element ( 3 ) and visible through the top part ( 21 ) of the external cap ( 2 ); the first and the second signal are located so as to align with each other in the intermediate opening.

19. The capsule according to claim 17 , wherein the top part ( 21 ) of the external cap ( 2 ) comprises at least one portion that is transparent and/or the conformation of which consists of a polarized or non-polarized lens or set of lenses.
