CAPPING UNIT CONTAINING CAP WITH ANNULAR ELEMENT FOR OPENING INDICATION, MADE AS SINGLE WHOLE WITH IT Russian patent published in 2022 - IPC B65D75/58 

FIELD: packaging.

SUBSTANCE: invention relates to a capping unit, a container equipped with a capping unit, and to a method for the manufacture of filled containers equipped with a capping unit. The capping unit contains product (10, 10’, 10”, 410) and cap (40, 40’, 40”, 40”’, 440) made with annular element (50, 50’, 50”, 450) for opening indication, made as a single whole with it. The product additionally contains ring-shaped flange structural element (20) with an annular flange part and peripheral protective rim part (25), so that upper surface (21a) of the flange part and the protective rim part define boundaries of annular deepening (30) around neck (14). The annular element for opening indication is formed as a single whole with a lower edge of skirt (42) of the cap by means of one or more destructible jumpers (70). The annular element contains annular flange part (51) of the annular element, which has upper surface (51a) and lower surface (51b). A set of hook-shaped elements (53) is formed as a single whole with the lower part of the flange part of the annular element, and the annular flange part, on the neck, is made with a set of passage holes (18) for hook-shaped elements. Each passage hole for the hook-shaped element is made with the possibility of reception of the hook-shaped element in the installation of the cap with the annular element for opening indication, made as a single whole with it, in the axial direction on the neck by means of axial fixing movement, while hook-shaped part (55) of each hook-shaped element is fixed with latching under lower surface (21b) of the annular flange part on the neck of the product. The periphery of the annular flange part of the annular element is made with a shape providing a possibility of its placement inside the protective rim part, and the rim part prevents access in a lateral direction from the outside to a conjugation zone between flange parts.

EFFECT: provision of a possibility of reduction in use of plastic with simultaneous saving or even increase in the strength of connection between a ring for opening indication and a product.
