Abstract

A cap for a container comprising a ferrule to be fixedly attached to the neck of the container, the ferrule comprising an upper wall and a tubular skirt extending downwardly from the upper wall; a tamper evidence mechanism connected with the ferrule; an overseal button removably arranged on top of the upper wall of the ferrule so as to at least fully cover the tamper evidence mechanism, the overseal button being connected to the tamper evidence mechanism such that upon first removal of the overseal button the tamper evidence mechanism is irreversibly damaged. The overseal button comprises at least one translucent portion arranged to extend over the at least one portion of the tamper evidence mechanism which is irreversibly damaged upon first removal of the overseal button.

First claim

The invention claimed is:

1. A cap for a container containing a pharmaceutical product, the cap comprising:
a ferrule to be fixedly attached to a neck of the container containing a pharmaceutical product, the ferrule comprising an upper wall and a tubular skirt extending downwardly from the upper wall;
a tamper evidence mechanism connected with the ferrule; and
an overseal button removably arranged on top of the upper wall of the ferrule in a manner so as to at least fully cover the tamper evidence mechanism, the overseal button being connected to the tamper evidence mechanism such that upon first removal of the overseal button from the ferrule at least a portion of the tamper evidence mechanism is irreversibly damaged,
wherein the overseal button comprises at least one translucent portion arranged to extend over the at least one portion of the tamper evidence mechanism which is irreversibly damaged upon first removal of the overseal button from the ferrule,
wherein the overseal button further comprises an identification portion which is different from the at least one translucent portion in at least one property, the at least one property being selected such that it allows for visual differentiation of the identification portion and the at least one translucent portion,
wherein the overseal button comprises an opaque colored outer ring and the at least one translucent portion is surrounded by the opaque colored outer ring, and
wherein the overseal button comprises a centrally arranged opaque colored hub and the at least one translucent portion of the overseal button is arranged between the centrally arranged opaque colored hub and the opaque colored outer ring.

2. The cap according to claim 1 , wherein the at least one property of the identification portion allowing for differentiation of the identification portion and the at least one translucent portion is selected from opacity, color, surface roughness, or combinations thereof.

3. The cap according to claim 1 , wherein the tamper evidence mechanism comprises a hub and wherein the upper wall of the ferrule comprises an outer portion which is connected to the skirt and surrounds the hub of the tamper evidence mechanism, wherein the hub of the tamper evidence mechanism is connected to the outer portion of the ferrule through a breakable connection, wherein the overseal button comprises a clamping member and wherein the hub comprises a through-opening which is centrally arranged in the hub, with the clamping member of the overseal button extending through the centrally arranged through-opening of the hub and clamping the overseal button to the hub of the tamper evidence mechanism.

4. The cap according to claim 3 , wherein the outer portion of the upper wall of the ferrule is an annular portion, wherein the hub of the tamper evidence mechanism is a centrally arranged circular disc comprising the centrally arranged through-opening, and wherein the centrally arranged through-opening has a circular shape.

5. The cap according to claim 4 , wherein the breakable connection comprises one or more bridging webs which are connected to the hub of the tamper evidence mechanism as well as to the outer portion of the upper wall of the ferrule, each individual bridging web being arranged at an individual angular position when viewed in circumferential direction, with the individual angular positions of the individual bridging webs being different from one another.

6. The cap according to claim 5 , wherein the breakable connection comprises at least four individual bridging webs, in particular at least six individual bridging webs, with the individual bridging webs being arranged at equally spaced individual angular positions, and wherein the at least one translucent portion of the overseal button is arranged to extend over at least one of the bridging webs.

7. The cap according to claim 3 , wherein the breakable connection comprises a scoring line connecting the centrally arranged hub of the tamper evidence mechanism to the outer portion of the upper wall of the ferrule, and wherein the translucent portion of the overseal button is arranged to extend at least partly over the scoring line.

8. The cap according to claim 1 , wherein the centrally arranged opaque colored hub is connected to the opaque colored outer ring through at least one opaque colored web.

9. The cap according to claim 8 , wherein the at least one opaque colored web comprises a plurality of individual opaque spokes arranged to extend from the opaque colored hub to the opaque colored outer ring in a star-like manner.

10. The cap according to claim 9 , wherein the at least one opaque colored web comprises a single opaque conical web with the narrow end of the opaque conical web being connected to the opaque colored hub and the wide end of the conical web being connected to the opaque colored outer ring.

11. The cap according to claim 1 , wherein the overseal button is a two-component injection molded piece.

12. The cap according to claim 1 , wherein the identification portion identifies at least one of a type of the pharmaceutical product, a concentration of the pharmaceutical product, and a manufacturer of the pharmaceutical product.

13. A container containing a pharmaceutical product, the container comprising a neck having an opening for allowing access to the interior of the container, a sealing stopper being arranged in the opening in the neck, and a cap, wherein the cap comprises:
a ferrule comprising an upper wall and a tubular skirt extending downwardly from the upper wall,
a tamper evidence mechanism connected with the ferrule; and
an overseal button removably arranged on top of the upper wall of the ferrule in a manner so as to at least fully cover the tamper evidence mechanism, the overseal button being connected to the tamper evidence mechanism such that upon first removal of the overseal button from the ferrule at least a portion of the tamper evidence mechanism is irreversibly damaged,
wherein the overseal button comprises at least one translucent portion arranged to extend over the at least one portion of the tamper evidence mechanism which is irreversibly damaged upon first removal of the overseal button from the ferrule,
wherein the overseal button further comprises an identification portion which is different from the at least one translucent portion in at least one property, the at least one property being selected such that it allows for visual differentiation of the identification portion and the at least one translucent portion,
wherein the cap is arranged to cover the sealing stopper with the lower end of the skirt of the cap engaging a rim on an outer wall of the neck of the container containing a pharmaceutical product,
wherein the overseal button comprises an opaque colored outer ring, the at least one translucent portion being surrounded by the opaque colored outer ring, and
wherein the overseal button comprises a centrally arranged opaque colored hub and the at least one translucent portion of the overseal button is arranged between the centrally arranged opaque colored hub and the opaque colored outer ring.

14. The container according to claim 13 , wherein the at least one property is selected from opacity, color, surface roughness, and combinations thereof.

15. The container according to claim 13 , wherein the tamper evidence mechanism comprises a hub, the upper wall of the ferrule comprising an outer portion that is connected to the skirt and surrounds the hub, the hub being connected to the outer portion of the ferrule through a breakable connection, the overseal button comprising a cl
