FIELD: packaging industry.
SUBSTANCE: invention relates to sealing fixtures of bottles, but can be used for sealing and other vessels for liquid and loose substances. The safety plug 1 is placed on the bottle 2 with a circular ledge 3, radial ribs 4. The safety plug 1 consists of a dropping funnel 5 with a tube 6, covers 7, a metal cap 8 with a radial facet 9, a gasket 10 with a valve 11. The cover 7 has a cone-shaped corrugated indicator ring 13. The metal cap 8 has a circular dividing bend 14 which divides the cap into the metal cover 15 and the skirt 16. When any section of such indicator ring 13 is impacted the force is transmitted to other sections by means of elastic deformations. That complicates its filling under the upper edge of the skirt 16 of the metal cap 8.
EFFECT: design improvement.
