FIELD: packaging industry.
SUBSTANCE: invention relates to a packaging system and the use of such system. The packaging system contains a vessel (1) which contains a neck (2) forming an axis (X-X), and a plug (10) intended for plugging of the neck which contains a skirt (12) adapted for removable fastening on the neck. For the purpose of fast and easy check of the appropriate location of the plug on the neck when the vessel is closed, according to the present invention the means for visual check are provided to check that the system is in the closed position which is the result of the application of a previously established effort for ensuring of the interaction of the skirt with the neck. The named means contain: the first angular position indicators (20, 22) around the axis between the neck and the skirt which are located respectively on the neck and the skirt so that between them there is an angular interval which value, in essence, is equal to the first previously established value when the packaging system is in the named closed state, and the second indicators (21, 23) of position along the axis between the neck and the skirt. The second indicators separated from the first indicators are located respectively on the neck and the skirt and placed in parallel to each other so that between them there is an interval (Δ) in the axial direction which value is less than the second previously established value when the packaging system is in the named closed state.
EFFECT: design improvement.
