A third member is arranged coaxial with the first and second members. A damper element is provided between the first and the third members in order to dampen the relative rate of rotation between the members. A first spring is arranged between the second and the third tubular members, which first spring is connected to the respective second and third members so that relative rotation between the tubular members is permitted in a first direction, when the cover is pivoted towards a first position, and prevented in a second direction, when the cover is pivoted towards a second position. A container provided with such a hinge is described. ## Claims ### Claim 1 A hinge on as cover for a container, said hinge having a pivot axis and comprising: at least one first member fixed against rotation; at least one second member rotatable about said axis, said first and second members being arranged coaxially along said axis; a third member arranged coaxial with the first and second members; a damper element between the first and the third members in order to dampen the relative rate of rotation therebetween; a first spring arranged between the second and the third members, said first spring being connected to the respective second and third members so that relative rotation therebetween is permitted in a first direction, when the cover is pivoted towards a first position, and prevented in a second direction, when the cover is pivoted towards a second position; and a second spring arranged between the first and second members, said second spring being connected to the respective first and second members so that rotation of the second member exerts a torque on said second member towards the second position of the cover. ### Claim 2 (depends on 1) The hinge according to claim 1, wherein the first spring is acted on by the second member and is arranged to expand and slide relative to the third member when the second member is being rotated in the first direction. ### Claim 3 (depends on 1) The hinge according to claim 1, wherein the first spring is acted on by the second member and is arranged to contract and be locked relative to the third member when the second member is being rotated in the second direction. ### Claim 4 (depends on 1) The hinge according to claim 1, wherein the first, second and third members are tubular members. ### Claim 5 (depends on 4) The hinge according to claim 4, wherein the damper element is provided between at least an outer surface of the third member and an inner surface of the first member. ### Claim 6 (depends on 4) The hinge according to claim 4, wherein the damper element is provided between at least an inner surface of the third member and an outer surface of the first member. ### Claim 7 (depends on 4) The hinge according to claim 4, wherein a first end section of the third member is arranged in a cylindrical or an annular recess in the first member. ### Claim 8 (depends on 4) The hinge according claim 4, wherein a second end section of the third member is arranged in a cylindrical or an annular recess in the second member. ### Claim 9 (depends on 4) The hinge according claim 4, wherein the damper element provided between the first and the third members comprises a damping fluid in a space between said first and third members. ### Claim 10 (depends on 1) The hinge according to claim 1, wherein the at least one second member comprises a first section containing the first spring and a second section containing the second spring, said first and second sections being mounted at opposite ends of the first member. ### Claim 11 (depends on 1) The hinge according to claim 1, further comprising a blocking mechanism to block the hinge in its first position. ### Claim 12 (depends on 11) The hinge according to claim 11, wherein the blocking mechanism is spring loaded towards its blocking position. ### Claim 13 (depends on 12) The hinge according to claim 12, wherein the blocking mechanism is mounted on an attachment portion of the hinge. ### Claim 14 (depends on 1) A container comprising a hinge according to claim 1. ### Claim 15 (depends on 14) The container according to claim 14, wherein the container is a waste bin with a lid arranged to be pivoted, said lid being attached to the waste bin by said hinge. ### Claim 16 (depends on 14) The container according to claim 14, wherein the container is a tissue or towel dispenser with a cover arranged to be pivoted, said cover being attached to the dispenser by said hinge. ### Claim 17 (depends on 14) The container according to claim 14, wherein the container is a liquid or viscous fluid dispenser with a cover arranged to be pivoted, said cover being attached to the dispenser by said hinge.
