The dispensing head includes a plastic flange provided with a sealing skirt and an outer catching skirt provided with a snap-fit rim on its inner surface, wherein the neck has a wall and the shoulder has a wall, both said walls being of substantially the same thickness as the sidewall.

Abstract: There is a flexible tube having a neck in which an outer surface has a securing attachment and a transverse end wall bearing a cylindrical vent. There is also a rigid end cap having a sealing shirt and a securing skirt having a securing attachment matching that of the neck. The vent of the flexible tube and sealing and securing skirt are arranged so as to obtain longitudinal locking of the rigid end cap on the neck by a simple longitudinal translational movement.

Abstract: A tube provided with a head and a skirt having an orthogonal cross section of particular shape in which the largest inscribed circle has a diameter D. The head, which is designed for fixing of a rigid closure, is provided with a circular cylindrical wall extending towards the inside of the tube and enclosing an orifice concentric to the inscribed circle and having a large diameter, typically more than 0.8D, and takes up substantially the internal volume of the skirt end over a height less than D, preferably less than D/3. The invention is further directed to a closure element, in particular a convenience closure, adapted for fixing substantially irreversibly on the tube head, comprising a base having an external outline matching the shape of the orthogonal cross section of the tube skirt, and a skirt having a diameter in the range of 0.5D to 0.9D.

Abstract: The invention concerns a flexible tube comprising a neck whereof the outer surface is provided with irreversible securing means and whereon is mounted a transverse end wall bearing a cylindrical vent. The invention also concerns a rigid end cap provided at least with a sealing shirt and a securing skirt provided with matching securing means, said vent of the flexible tube and said sealing and securing skirt being arranged so as to obtain sealed attachment with longitudinal locking of the rigid end cap on the neck by a simple longitudinal translational movement. Additional means such as those described in FR 2 707 256 or FR 9901530 (elliptical tube) enable by slight rotation after depression, complete rotational locking.

Abstract: Process for manufacturing a metal can with a threaded neck on which a removable head can be fitted, includes the steps of forming a can with a closed bottom end, a cylindrical wall and an open top end, forming a neck at the open top end, obtaining a ring with a spindle hole of known diameter and a threaded external surface, sleeve fitting the ring by driving the spindle hole over the neck, and plastically expanding the neck by an amount sufficient that its outer diameter exceeds the diameter of the spindle hole when unstressed.

Abstract: Apparatus for manufacturing flexible tubes comprising a skirt and a head provided with a neck and a shoulder linking the neck to the skirt, the apparatus having a first zone devoted to manufacturing the skirts, a second zone devoted to manufacturing the flexible tubes, a third zone devoted to finishing the flexible tubes thus produced, a first transfer device transferring the skirts in continuous motion from the first zone to the second zone, and a second transfer device transferring, in continuous motion synchronized with the former, the tubes from the second zone to the third zone.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A tube (1) including a head (2) of molded plastic composition and a flexible sidewall (4) affixed to this head (2), including a neck (6 and 7) with an opening (8) connected by a detachable sealed annular portion (11) to a continuous bottom (12) of a closure (20) in the form of an inverted hat topping the neck, the bottom (12) of the closure being joined to an external sidewall (13) of the closure, and the closure carrying a means (17) for reclosing the neck in a sealed manner after the detachment of said annular portion (11). The neck has an inner annular edge (7) demarcating its opening (8), the edge (7) and an annular portion (14 and 15) of the closure (20) that extends from the junction of the base (12) and the annular detachable portion (11) up to an annular portion of the external sidewall (13) located above the connection (16) of the base (12) and the sidewall (13) each have a thickness of between 1.1 and 1.6 mm, their rigidity thus promoting the detachment of the detachable annular portion (11).
