FLAP CAP Russian patent published in 2022 - IPC B65D47/08 

FIELD: storage.

SUBSTANCE: invention relates to a flap cap with a closure element (1) and a flap lid (2), interconnected by means of at least one hinge (9) and by means of at least one tension band (10) in order to ensure a triggering effect when opening and/or closing the hinged lid. Said at least one tension band (10), in the unloaded state, in the cross section perpendicular to the axis of rotation of said at least one hinge, has at least three curved sections, and between the corresponding two adjacent curved sections passes along one substantially straight section, and also does not bend in opposite directions. Alternatively, in the unloaded state of said at least one tension band (10), in the cross section perpendicular to the axis of rotation of the hinge, the distance from the tangent to the midline between the edges of said at least one tension band at the point of connection of the tension band with the closure element and, accordingly, with the flap lid to the axis of rotation of said at least one hinge (9) is at most tripled, preferably at most doubled, more preferably at most single, and especially preferably at most half the thickness of said at least one tension band at the corresponding point of connection.

EFFECT: breakage or tearing of the tension band occurs less frequently.
