Patent ID: 7562783

Claim:
Functional insert for insertion into the neck of a bottle through an opening, comprising: a body constructed and arranged for insertion into the neck by force fitting, the body comprising a cylindrical wall having a central axis coincident with the central axis of the neck when the body is inserted into the neck, and normal to the opening, the cylindrical wall defining an outer surface, with at least one flexible rib on the outer surface extending radially outwardly with respect to the central axis, for forming a sealed junction with an inner surface of the neck when the body is inserted into the neck, the rib including an upper surface, a functional element, and an adhesive supported on at least one of the upper surface of the rib and the outer surface of the wall above the upper surface of the rib, the adhesive selected to bond to the neck and having a consistency or viscosity such that the adhesive will only creep under a stress that compresses the adhesive between the rib and the body when, with the body inserted into the neck, the rib curls, the adhesive being present in an amount sufficient that the adhesive comes into contact with the neck so as to fix the body to the neck at an adhesive contact area and thereby prevent upward axial displacement of the body under axial stress.
