Patent number: 6382438Abstract: A flexible tube and a container manufactured with a detachable cover that is reusable as a cap. The detachable cover includes a plastic top member and a skirt. The plastic top member has a neck and a cover. The neck is connected to the cover by a tearable ring-shaped part. The cover has a circular plate with an interlocking mechanism, for example, at least three lugs projecting radially from a periphery of the circular plate. The skirt has a common axis of symmetry with the cover and has an inner surface that follows the periphery of the circular plate. The skirt also has a receiving mechanism, for example, at least three cavities that are positioned to receive the at least three lugs such that the skirt becomes immobilized with respect to the plastic top member. The skirt encircles the outer surface of the neck. The skirt and the cover are configured to cap the flexible tube or container after tearing the tearable ring-shaped part.Type: GrantFiled: November 27, 2000Date of Patent: May 7, 2002Assignee: Cebal SAInventors: Bernard Schneider, Jean-Paul Meausoone

Patent number: 6375020Abstract: Improved cap system for aluminum and/or steel bottles, consisting of a plastic cap adapted to the neck of an aluminum and/or steel bottle, including its placing procedure and securing. The edge of the cap acts as a contact surface for closing and sealing the bottle by thermofusion. The outside cap (1) has an inside edge (2) with small teeth (10) on its surface, underneath its upper end (3), resulting in the contact surface for closing and sealing the bottle (8) or container by thermofusion. The thickness of the bottle is reduced at the end zone (4) of its neck (9), facilitating its deformation and ensuring the attachment of the cap on the neck (9) of the bottle by means of introducing a suitable mold (5) by pressure. Thus, the cap cannot be moved between projections (6) of the bottle and inside ribs (7) of the cap.Type: GrantFiled: July 12, 2000Date of Patent: April 23, 2002Assignee: Cebal Entec, S.A.Inventor: Eugenio Roures Marquez

Patent number: 6192569Abstract: The invention relates to a process for manufacture of a top 1 intended to be attached on a container or a flexible tube 50 and comprising a neck 3 the opening 7 of which is connected by a tearable ring-shaped part 10 to a cover 20 serving as an impervious stopper prior to breaking of the ring-shaped part and then being able to serve for recapping. The cover 20 is extended by a plate 30 the periphery 31 of which has a common axis of symmetry with the tearable ring-shaped part 10 and is provided with at least three lugs 32. The skirt 40 is open at one end; its inner surface 46 is partially cylindrical, its section following the exact shape of the periphery 31, except for the lugs, of the plate 30, and is provided with at least three cavities 41 intended to accommodate said lugs. The skirt is drawn around the plate 30 to the point of immobilization, brought about by the insertion of the lugs 32 on the plate 30 into the cavities 41 of the skirt 40.Type: GrantFiled: April 18, 1997Date of Patent: February 27, 2001Assignee: Cebal SAInventors: Bernard Schneider, Jean-Paul Meausoone

Patent number: 6170705Abstract: The invention concerns a double-walled tube (1) for storing and dispensing hazardous products, comprising an inner tube (10) with a skirt (13), a shoulder (12) and an inner neck (11) delimiting an inner orifice (14), a metal tube with a skirt (25), a shoulder (24) and an outer neck (21), the two tubes being mutually connected at their necks (11 and 21) by a joining piece (30) comprising a bottom (34) and at least an outer skirt (35) enclosing the two necks (11 and 21). The invention is characterised in that the joining piece (30) is provided with an inner skirt (31) with its outer wall having a globally truncated profile, such that, when the joining piece (30) is forcefully pushed down, said inner skirt (31) causes the median parts of the necks (11 and 21) to expand at their circumference, thus widening the ends of said necks.Type: GrantFiled: August 6, 1999Date of Patent: January 9, 2001Assignee: Cebal SAInventors: Bernard Schneider, Herv{acute over (e)} Bodet

Patent number: 5992656Abstract: A plastic tube with a tubular tube body which is connected through a shoulder to a neck having an external thread and with a screw cap which can be screwed with an internal thread onto the external thread of the neck. The shoulder is injection molded onto the corresponding end of the tube body, wherein the shoulder and the externally threaded neck are constructed in one piece. The shoulder and the adjacent end of the tube body have a polygonal cross-section and the same polygonal cross-section continues over the length of the tube body. At least two side surfaces of the tube body extend from this transition point essentially plane or with a straight surface toward the end of the tube.Type: GrantFiled: January 22, 1997Date of Patent: November 30, 1999Assignee: CEBAL Verpackungen GmbHInventors: Francois Dujardin, Richard Frohling
