1. A can end for a metal beverage can, said can end comprising: a cap top, arranged with a connection to a pull tab configured to remove said cap top from a top portion of said can end along a pre-defined groove on the top portion, to thereby create a drinking or pouring aperture;an elastic resilient element attached to the can end; anda resiliently operated shut-off valve that is part of or is connected to said elastic resilient element and that is configured to close and seal the drinking or pouring aperture after drinking or pouring, by an action of said elastic resilient element;wherein said cap top is configured to remain located, after said removal, on top of said shut-off valve, andwherein said elastic resilient element has a holding element configured to hold said shut-off valve in an opened position upon moving said cap top. 2. The can end according to claim 1, wherein said holding element is configured to hold said shut-off valve in said opened position upon moving said cap top by said pull tab. 3. The can end according to claim 1, wherein said cap top has an upper surface and comprises a raised lip-contact portion on said upper surface. 4. The can end according to claim 1, wherein said shut-off valve comprises a relief valve, actuatable by interaction with said cap top and configured to release gas pressure from inside the can upon the first pressure being exerted on said relief valve. 5. The can end according to claim 1, wherein said holding element is configured to release said shut-off valve, when in said opened position, so as to close and seal said drinking or pouring aperture, by upsetting or dropping a can comprising said can end. 6. The can end according to claim 1, wherein said holding element is configured to release said shut-off valve, when in said opened position, so as to close and seal said drinking or pouring aperture, by exertion of a force on an element selected from the group consisting of said elastic resilient element, said shut-off valve, and said cap top. 7. The can end according to claim 1, wherein said shut-off valve comprises a first engaging element and wherein said holding element comprises a second engaging element configured to engage said first engaging element. 8. The can end according to claim 1, wherein said shut-off valve has a circumference and comprising a seal around said circumference. 9. The can end according to claim 1, further comprising an intermediate element between said elastic resilient element and said top portion of said can end. 10. The can end according to claim 1, wherein said can end has a first side and a second side opposite to said first side, wherein said second side is configured to receive a first side of an identical can end for forming a stack of can ends. 11. A metal beverage can, comprising a can body and the can end recited in claim 1. 12. A method for producing a metal beverage can comprising a can body and a can end, the method comprising: producing the can end for the metal beverage can, said can end comprising: a cap top, arranged with a connection to a pull tab configured to remove said cap top from said can end along a pre-defined groove, to thereby create a drinking or pouring aperture;an elastic resilient element attached to the can end; and a resiliently operated shut-off valve that is part of or is connected to said elastic resilient element and that is configured to close and seal the drinking or pouring aperture after drinking or pouring, by an action of said elastic resilient element; wherein said cap top is configured to remain located, after said removal, on top of said shut-off valve and wherein said elastic resilient element has a holding element configured to hold said shut-off valve in an opened position upon moving said cap top;producing the can body;attaching the can end to the can body. 13. A method for using a reclosing metal beverage can, said can comprising a can body and a can end, the method comprising: actuating a pull tab of said can end, thus removing a cap top of said can end along a predetermined groove of said can end, thus creating a drinking or pouring aperture;resiliently opening, by said actuating of said pull tab, a shut-off valve that is connected to an elastic resilient element of said can end and that is configured to close and seal said drinking or pouring aperture after drinking or pouring, by an action of said elastic resilient element, wherein said removed cap top remains located on top of said shut-off valve; andholding said shut-off valve in an opened position by said elastic resilient element. 14. The method according to claim 13, comprising engaging a first element of said shut-off valve with a second element of said elastic resilient element, thus holding said shut-off valve in said opened position. 15. The method according to claim 13, comprising exerting a force on said elastic resilient element or on said shut-off valve or on both said elastic resilient element and said shut-off valve, when said shut-off valve is in said opened position, thus releasing said shut-off valve from said elastic resilient element and thus closing said drinking or pouring aperture. 16. The method according to claim 15, wherein said exerting of said force comprises tapping against said can, thus releasing said shut-off valve from said elastic resilient element and thus closing said drinking or pouring aperture.
