Closure for a container with - a base element, - a flip-top lid attached to said base element by a hinge such that the flip-top lid can be moved between an opened and a closed position, - a tamper evident unit for indicating whether the flip-top lid has been opened at least once by a user or not, said tamper evident unit comprising a first tamper evident element and a second tamper evident element, which are, when said closure is in its as-manufactured status or when said flip-top lid has not been opened yet by the user, connected to each other by at least one frangible bridge, wherein said first tamper evident element is retained relative to the base element such that it is movable between a first position and a second position, wherein said first tamper evident element is in its first position, when said closure is in its as-manufactured status or when said flip-top lid has not been opened yet by the user, and said first tamper evident element is in its second position, when said flip-top lid has been opened at least once by the user, wherein said flip-top lid is at least in part transparent or translucent and/or comprises at least one opening or window, wherein said flip-top lid comprises a first inner extension wall with first engagement means and wherein said second tamper evident element comprises second engagement means, said first engagement means and second engagement means being arranged such that they engage with each other when said closure is in its as-manufactured status, and wherein said first and said second engagement means are arranged such that a minimum force FE being necessary to disengage the first engagement means and second engagement means from each other is larger than a force FD being necessary to destroy the at least one frangible bridge, characterised in that said base element comprises at least one spring element being arranged such that it applies a force FS onto said first tamper evident element into a direction towards the second position of said first tamper evident element, said force FS being smaller than said minimum force FD being necessary to destroy the at least one frangible bridge. - a base element, - a flip-top lid attached to said base element by a hinge such that the flip-top lid can be moved between an opened and a closed position, - a tamper evident unit for indicating whether the flip-top lid has been opened at least once by a user or not, said tamper evident unit comprising a first tamper evident element and a second tamper evident element, which are, when said closure is in its as-manufactured status or when said flip-top lid has not been opened yet by the user, connected to each other by at least one frangible bridge, wherein said first tamper evident element is retained relative to the base element such that it is movable between a first position and a second position, wherein said first tamper evident element is in its first position, when said closure is in its as-manufactured status or when said flip-top lid has not been opened yet by the user, and said first tamper evident element is in its second position, when said flip-top lid has been opened at least once by the user, wherein said flip-top lid is at least in part transparent or translucent and/or comprises at least one opening or window, wherein said flip-top lid comprises a first inner extension wall with first engagement means and wherein said second tamper evident element comprises second engagement means, said first engagement means and second engagement means being arranged such that they engage with each other when said closure is in its as-manufactured status, and wherein said first and said second engagement means are arranged such that a minimum force FE being necessary to disengage the first engagement means and second engagement means from each other is larger than a force FD being necessary to destroy the at least one frangible bridge, characterised in that said base element comprises at least one spring element being arranged such that it applies a force FS onto said first tamper evident element into a direction towards the second position of said first tamper evident element, said force FS being smaller than said minimum force FD being necessary to destroy the at least one frangible bridge.
