US 2006/0230512 A1 · Sealing plug for sealing hollow flotation elements for use in a cover of a liquid-filled container

Abstract

The present invention provides a sealing plug for liquid-tight sealing off hollow flotation elements of a strip for a cover of a liquid-filled container. The sealing plug comprises an end plate and at least two protrusions extending from the end plate. The at least two protrusions comprise at least two lips. The end plate and the protrusions are formed of a first material and the lips are formed of a second material, the first material being harder than the second material. The at least two lips extend in a first direction including an angle between +/−90° and +/−180° with the direction in which the sealing plug is pushed into the hollow flotation elements and preferably have decreasing height starting from the end plate toward a free extremity of the protrusion.
