FUNCTIONAL INSERT FOR THE NECK OF A RECIPIENT, ESPECIALLY A BOTTLE, AND CLOSING CAPSULE COMPRISING SAID INSERT

摘要

The invention relates to a functional insert (3) comprising a body (30) which is provided with at least one flexible flange (31) on the outer surface thereof, for creating a tight connection with the neck (4), and a functional element (6, 7). Said functional insert is characterised in that: a) it comprises an adhesive (5) which is typically carried by the flange (31) and is selected in such a way that it adheres to the neck (4) of the recipient, and b) the adhesive (5) is a typically permanent adhesive selected in terms of its consistency or viscosity such that it only squeezes out under stress. In this way, any axial displacement towards the top of the functional insert (3) is prevented by fixing the body to the neck of the recipient by means of an adhesive contact region.
