TAMPER-EVIDENT SEAL Russian patent published in 2022 - IPC E05B39/02 

FIELD: seals.

SUBSTANCE: invention relates to sealing apparatus and can be used, in particular, for sealing various objects equipped with locking units (doors of containers, vehicles, boxes, suitcases, etc.), as well as necks of bags made of various materials (woven as well as non-woven), in places of both permanent and temporary storage, including for the duration of transporting by all modes of transport. Tamper-evident seal is made of plastic and consists of a rectangular body (1) with inlet and outlet holes, made on opposite end transverse sides of the body (1), respectively. Locking elements are installed in the inner cavity of the body (1). One of the lateral longitudinal sides is mated with a flexible strap (2) with a rounded end (3), made with a rectangular cross section, whereon perforation is located. The perforation is made forming inclined protrusions (4) above through holes (6). The locking elements are made in the form of two spikes (5) located at an acute angle formed between the base of the spikes (5) and the longitudinal side of the body (1). The through holes (6) are formed by the inclined protrusions (4) located on the strap (2), made at an angle equal to the angle of inclination of the spikes (5). One of the end longitudinal sides of the body (1) is connected with a rectangular label flag (7). The lateral longitudinal side of the body (1), opposite to the lateral longitudinal side on the inner surface whereof the bases of the spikes (5) are located, is made with a protrusion (8). The height of the inner cavity of the body (1) at the site of the protrusion (8) is greater than the height of the strap (2) with the inclined protrusions (4). The length of the spikes (5) is greater than the height of the inner cavity of the body (1) at the site of the protrusion (8).

EFFECT: increase in the forensic tolerance (resistance) to known methods for unauthorised intrusion, as well as forensic identification with the improved structural manufacturability of the apparatus.
