Foil for closing an opening of a container, a container part and a container, and a method and apparatus for making same

1. A foil for closing an opening in a container, such as an easy opening container, comprising foil to be adhered to the container, which foil comprises a tab for releasing the foil from the container, wherein the tab is folded on the foil and connected thereto via a connector; wherein the connector is a protrusion provided in the foil that extends into a complimentary cavity provided in the tab; wherein the tab is provided with breakout means that encircle the connector such that upon actuating the tab a visible and irreparable broken out part is formed and adhered to the foil and a hole is formed in the tab; wherein the breakout means are formed as at least one opening in the tab, wherein the at least one opening in the tab is formed as a first slot passing through the tab and located at a first lateral side of the connector and a second slot passing through the tab and located at a second lateral side of the connector such that the first slot and the second slot converge beyond the connector towards an end of the tab that is integrally connected to the foil and a third slot in an area between a free end of the tab and the connector, wherein the first slot extends a first length around the connector between a first tab bridge and a second tab bridge, the second slot extends a second length around the connector between the second tab bridge and a third tab bridge, and the third slot extends a third length around the connector between the third tab bridge and the first tab bridge such that the first slot, the second slot, and the third slot surround the connector, and wherein visible remnants of the tab bridges remain with the broken out part when the tab is actuated.

2. The foil according to claim 1 , wherein the foil is made of metal, such as steel, tin plate and aluminum, optionally provided at at least one side with a polymer coating, or of a polymeric material.

3. A method for making the foil according to claim 1 , comprising the steps of:

i. providing the foil or foil strip;

ii. forming the breakout means formed as at least one opening and tab in the foil or foil strip;

iii. folding the tab onto the foil or foil strip;

iv. forming in the foil and folded tab the connector for connecting the tab to the foil via the connector; and

v. optionally forming at a step the foil out of the strip.

4. The method as claimed in claim 3 , wherein the breakout means are formed in the foil prior to the formation of the tab.

5. A method for making the foil according to claim 1 , comprising the steps of:

i. providing the foil or foil strip;

ii. folding the tab onto the foil or foil strip;

iii. forming in the folded tab breakout means formed as at least one opening in the tab and the connector for connecting the tab to the foil via the connector; and

iv. optionally forming at any step the foil out of the foil strip.

6. The method as claimed in claim 5 , wherein the breakout means are formed in the folded tab by at least one of laser means and mechanical means.

7. A container, having an opening closed by a foil to be adhered to the container, which foil comprises a tab for releasing the foil from the container, wherein the tab is folded on the foil and connected thereto via a connector; wherein the connector is a protrusion provided in the foil that extends into a complimentary cavity provided in the tab; wherein the tab is provided with breakout means that encircle the connector such that upon actuating the tab a visible and irreparable broken out part is formed and adhered to the foil and a hole is formed in the tab; wherein the breakout means are formed as at least one opening in the tab, wherein the at least one opening in the tab is formed as a first slot passing through the tab and located at a first lateral side of the connector and a second slot passing through the tab and located at a second lateral side of the connector such that the first slot and the second slot converge beyond the connector towards an end of the tab that is integrally connected to the foil and a third slot in an area between a free end of the tab and the connector, wherein the first slot extends a first length around the connector between a first tab bridge and a second tab bridge, the second slot extends a second length around the connector between the second tab bridge and a third tab bridge, and the third slot extends a third length around the connector between the third tab bridge and the first tab bridge such that the first slot, the second slot, and the third slot surround the connector, and wherein visible remnants of the tab bridges remain with the broken out part when the tab is actuated.
