Abstract

A safety closure for containers comprising a cover (3) and an internal element (4), the internal element being formed of a constraining portion (5) and a covering portion (6), the covering portion and the constraining portion being at least partially interconnected by means of at least a first preferential breakage zone (7B) which, when intact, joins them to each other, the constraining portion being provided with blocking means at the neck of a container with which the closure is intended to be associated and with first constraining means (10) which removably attach the cover, the internal element having sealing means (12) which, at least when the seal is intact, preserve the container content integrity.

First claim

The invention claimed is:

1. A safety closure for containers comprising a cover and an internal element, the internal element being formed by a constraining portion and by a covering portion, that after use may be positioned again on the container, the covering portion and the constraining portion being interconnected by at least a first preferential breakage zone which, when intact, joins them to each other, the constraining portion being provided with blocking means at the neck of a container with which the closure is intended to be associated, and first removable constraining means associated with the cover, the internal element having sealing means which, at least when the seal is intact, preserve the container content integrity;
wherein the sealing means is located on the covering portion and/or wherein the sealing means comprises an annular lip projecting from the covering portion and adapted to cooperate with an internal edge of a mouth of the container with which the closure is intended to be associated;
wherein the covering portion may be reapplied and covered by the cover.

2. The closure of claim 1 , wherein the internal element comprises a removable seal joined to the covering portion and to the constraining portion, respectively, by means of the first preferential breaking zone and a second preferential breaking zone.

3. The closure of claim 1 , wherein the covering portion has an annular groove adapted to cooperate with a free edge of the container for the reciprocal centering between the covering portion and the container, when the covering portion is on the container, and/or wherein the covering portion has removable anchoring means with said container and/or with said constraining portion, and/or wherein said removable anchoring means comprises at least one edge adapted to cooperate in an undercut with a flange suitably located on said container and/or on said constraining portion.

4. The closure of claim 1 , wherein the blocking means are of an unremovable undercut type, with a snap-engagement and/or wherein the blocking means have torsional coupling means between the container and the constraining portion.

5. The closure of claim 4 , wherein the torsional coupling means have projections or recesses cooperating with recesses or projections obtained in the container.

6. The closure of claim 1 , wherein the removable constraining means comprise a thread adapted to cooperate with a corresponding counter-thread located on the cover.

7. The closure of claim 1 , wherein the internal element is made in a single piece, by injection molding of plastics.

8. A closure-container system comprising a container on which a closure is positioned according to claim 1 .

9. The system of claim 8 , wherein the container has an annular protuberance for the coupling with said anchoring means, and/or wherein the annular protuberance is provided with recesses or projections for housing projections or recesses of the constraining portion.

10. A safety closure for containers comprising a cover and an internal element, the internal element being formed by a constraining portion and by a covering portion, that after use may be positioned again on the container, the covering portion and the constraining portion being interconnected by means of at least a first preferential breakage zone which, when intact, joins them to each other, the constraining portion being provided with blocking means at the neck of a container with which the closure is intended to be associated, and first removable constraining means associated with the cover, the internal element having sealing means which, at least when the seal is intact, preserve the container content integrity;
wherein the covering portion has an annular groove adapted to cooperate with a free edge of the container for the reciprocal centering between the covering portion and the container, when the covering portion is on the container, and/or wherein the covering portion has removable anchoring means with said container and/or with said constraining portion, and/or wherein said removable anchoring means comprises at least one edge adapted to cooperate in an undercut with a flange suitably located on said container and/or on said constraining portion.

11. The closure of claim 10 , wherein the sealing means is located on the covering portion and/or wherein the sealing means comprises an annular lip projecting from the covering portion and adapted to cooperate with an internal edge of a mouth of the container with which the closure is intended to be associated.

12. The closure of claim 10 , wherein the blocking means is of an unremovable undercut type, with a snap-engagement and/or wherein the blocking means includes torsional coupling means between the container and the constraining portion.

13. The closure of claim 12 , wherein the torsional coupling means includes projections or recesses cooperating with recesses or projections of the container.

14. A closure-container system comprising a container on which a closure is positioned according to claim 10 .

15. The system of claim 14 , wherein the container has an annular protuberance for the coupling with said anchoring means, and/or wherein the annular protuberance is provided with recesses or projections for housing projections or recesses of the constraining portion.

16. A safety closure for containers comprising a cover and an internal element, the internal element being formed by a constraining portion and by a covering portion, that after use may be positioned again on the container, the covering portion and the constraining portion being interconnected by means of at least a first preferential breakage zone which, when intact, joins them to each other, the constraining portion being provided with blocking means at the neck of a container with which the closure is intended to be associated, and first removable constraining means associated with the cover, the internal element having sealing means which, at least when the seal is intact, preserve the container content integrity;
wherein the blocking means is of an unremovable undercut type, with a snap-engagement and/or wherein the blocking means includes torsional coupling means between the container and the constraining portion;
wherein the torsional coupling means includes projections or recesses cooperating with recesses or projections obtained in the container;
wherein the covering portion may be reapplied and covered by the cover.

17. The closure of claim 16 , wherein the sealing means is located on the covering portion and/or wherein the sealing means comprises an annular lip projecting from the covering portion and adapted to cooperate with an internal edge of a mouth of the container with which the closure is intended to be associated.

18. A closure-container system comprising a container on which a closure is positioned according to claim 16 .

19. The system of claim 16 , wherein the container has an annular protuberance for the coupling with said anchoring means, and/or wherein the annular protuberance is provided with recesses or projections for housing projections or recesses of the constraining portion.
