TAMPER EVIDENT SEALING DEVICE Russian patent published in 2021 - IPC B65D55/02 

FIELD: sealing technology.

SUBSTANCE: invention relates to means of hermetically sealing containers for the storage and transportation of liquid, consistency and bulk substances, namely, a lid for the neck of the container, in particular for spices, providing the possibility of visual inspection of the first opening. The technical problem the invention is aimed at solving is the development of a lid with a visual indication of the integrity (opening) of the package by combining the process of the first opening with the simultaneous opening of the dosing window. The expected result is achieved by the fact that in a sealing device with an opening control containing a housing made with the possibility of attachment to a container and an opening indicator, according to the invention, a dosing window is made in the end cover of the housing, the opening indicator is a hollow protrusion with side walls and a closed upper part located above the dosing window, one of the side walls of the opening indicator is made in the form of a semicircle, and the second is radial, while the housing is equipped with a rotary lid, in which a window corresponding in shape to the protrusion of the opening indicator is made for placing the protrusion, having a section made pointed in the form of a sharpened edge of a knife for cutting off the protrusion of the opening indicator when turning the lid.

EFFECT: ensuring complete tightness of the contents of the container during storage and transportation while simplifying the process of the first opening, ensuring the reliability of visual inspection and protection of products against counterfeiting.
