Abstract: A non-drip device for a bottle is in the form of an outwardly projecting peripheral lip. This peripheral lip has a triangular section of thickness that decreases out to an outer tip, the lip being defined by a top side and by a bottom side that, between them, form an angle lying in the range 5° to 45° . This outwardly projecting peripheral lip has a length advantageously lying in the range 0.1 mm to 0.8 mm. It may be provided at the top end of the skirt of a cover of the engagement type. In a variant embodiment, this lip may be formed integrally at the neck of the bottle. Such a lip structure makes it possible, at the time of pouring, and in effective manner, to avoid formation of drops that run down along the outside face of the bottle.

Abstract: An improvement to the plugs of bottles generally cylindrical in shape, delineated by a so-called upper end (4) and a so-called lower end (5). The cylindrical body (1) of the plug includes a cylindrical wall (6) made of moulded plastic material, inside which are provided—a sealing structure (20) at least liquid-proof, and—a stiffening honeycomb structure (7), also made of moulded plastic material, provided as single block with the cylindrical wall; the honeycomb structure (7) is formed of a plurality of longitudinal channels (10) juxtaposed, which channels (10) extend from the sealing structure (20) up to at least one of the upper (4) and/or lower (5) ends of the cylindrical body (1), at which they emerge, and it is in the form of a beehive structure, formed of channels, whereof at least the greater portion exhibits transversal hexagonal or substantially hexagonal section.
