Collapsible tube head () comprising a neck () which is fitted, with a port () and a shoulder (). The aforementioned head is fitted with a valve () which is inserted in the neck of the said collapsible tube, the said valve comprising a sealing means () which is connected to a ring support () having an opening (), the said sealing means being maintained in the closed position of the said opening when the tube is not compressed, and being maintained in the open position when the tube is compressed. The inner surface of the tube is provided with a bore () which is disposed close to the base of the said neck. The ring support is fixed to the bore by means of bonding, soldering or force fitting, and the said bore and ring support are preferably provided with complementary connection means, in particular a groove and rice grains.

Collapsible tube with a distributor head without air return

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.

Flexible tube provided with a large diameter neck and a rigid end cap

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.

Fixing head for tubes

A The invention discloses an assembly consisting of a head ( ) and an overcap ( ), the head having a cylindrical neck provided with a helical screw thread ( ), the overcap having a cylindrical skirt ( ) provided with a thread ( ) matching the neck thread ( ). The overcap carries an axial plate ( ) radially flexible and circumferentially rigid. The neck base ( ) is provided with at least an opening stop ( ), and at least a closure stop ( ), of lesser height. When the overcap ( ) is screwed on the head for mounting the assembly, the free end of the axial plate is urged into contact with a first wall ( ) of the opening stop ( ) and the axial plate whereof the free end is urged by a centrifugal motion, is elastically deformed then, folds down towards the neck in a space between the opening ( ) and closure ( ) stops, its displacement being thereby restricted.

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.

Container and flexible tube manufactured with a detachable cover that is reusable as a cap

The invention relates to a process for manufacture of a top,intended to be attached on a container or a flexible tube,and comprising a neck,the opening,of which is connected by a tearable ring-shaped part,to a cover,serving as an impervious stopper prior to breaking of the ring-shaped part and then being able to serve for recapping. The cover,is extended by a plate,the periphery,of which has a common axis of symmetry with the tearable ring-shaped part,and is provided with at least three lugs,. The skirt,is open at one end; its inner surface,is partially cylindrical, its section following the exact shape of the periphery,, except for the lugs, of the plate,, and is provided with at least three cavities,intended to accommodate said lugs. The skirt is drawn around the plate,to the point of immobilization, brought about by the insertion of the lugs,on the plate,into the cavities,of the skirt

Process for manufacture of a top for a container with a detachable cover reusable as a cap

The invention concerns a double-walled tube (,) for storing and dispensing hazardous products, comprising an inner tube (,) with a skirt (,), a shoulder (,) and an inner neck (,) delimiting an inner orifice (,), a metal tube with a skirt (,), a shoulder (,) and an outer neck (,), the two tubes being mutually connected at their necks (,and,) by a joining piece (,) comprising a bottom (,) and at least an outer skirt (,) enclosing the two necks (,and,). The invention is characterised in that the joining piece (,) is provided with an inner skirt (,) with its outer wall having a globally truncated profile, such that, when the joining piece (,) is forcefully pushed down, said inner skirt (,) causes the median parts of the necks (,and,) to expand at their circumference, thus widening the ends of said necks.

Double-walled tube with outer metal shell and inner plastic sheath

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).
