FIELD: personal demand items.
SUBSTANCE: essence of proposed inventions is that the protective label is formed on the sealing device in the area intended for application of identification information. Protective label has set clear boundaries separating from the base material (shell) of the sealing device, and differs from it in color, texture, shape, depth or other properties of polymer material. The substitution or forgery of the sealing device is detected by the absence or distortion of the set features including display features of marking on the protective label which are specific to the previously installed (original) sealing device.
EFFECT: increased reliability of sealing device protection against substitution and forgery, enhanced responsiveness to determine their authenticity in visual way, without the use of special equipment.
