This assembly consists of a base body having a guarantee wall that irreversibly bends, a cap assembly having a cap and a guarantee flap (which are integral in the intact closed configuration and include at least one breakable bridge connecting the guarantee flap to the guarantee wall), and an elastic hinge connecting the base body to the cap assembly.
[0007] From the specification of the invention of WO2021089149, there is known a container lid comprising a base element, a push-up lid attached to the base element via a hinge so as to be movable between an open position and a closed position, and a tamper-evident display unit for indicating whether the push-up lid has been opened by a user at least once. The tamper-evident display unit includes a first tamper-evident display element and a second tamper-evident display element, which are connected to each other by at least one breakable bridge when the lid is in the factory state or when the push-up lid has not yet been opened by the user. The first tamper-evident display element is attached to the base element so as to be movable between a first position and a second position, and the first tamper-evident display element is in its first position when the lid is in the factory state or when the lid has not been opened by the user, and the first tamper-evident display element indicating breakage is in its second position when the lid has been opened by the user at least once.
[0008] From the description of the invention of WO2014007612, there are known a lid assembly and a container provided with the lid assembly. This assembly consists of a cylindrical neck having a groove that forms an outlet at the upper part of the groove. A rotary cap designed to be manually rotated from the closed position to the open position is attached to the upper part of the cylindrical neck. The rotary cap further includes a ring with a guarantee bridge integrally formed on a diaphragm, and the guarantee seal is composed of at least two ring segments, each having a base part and an indicator part. The rotary cap provided with the guarantee seal ring is shaped such that when the user first rotates the cap from the closed position in the opening direction, the indicator part of the cap engages with a protrusion, and thereafter, further movement of the lid in the opening direction is blocked. The breakable bridge between the base part and the indicator part undergoes permanent deformation.
