Definitions
- the invention relates to a double-walled tube formed of an external metal casing and a flexible and protective internal casing, intended for storing and dispensing detergent products, hygiene products or cosmetic products which are particularly aggressive towards screws of the outer metal casing, such as hair dyes.
- Metal tubes are appreciated for their high restitution rates.
- the perfect plasticity of the metal prevents any return of the product towards the inside of the tube when the user has finished pressing on the skirt of the tube.
- the metal envelope is very sensitive to corrosion when it comes to containing particularly acidic or alkaline products.
- Patent application FR 2 322 058 presents a double-walled tube made up of two tubes produced separately and joined by their necks.
- the metal tube constitutes an external envelope which is protected from the aggressive product by a internal plastic tube.
- the top end of the neck of the inner plastic tube greatly exceeds the top end of the neck of the outer metal tube.
- the protruding part is flared in the shape of a trumpet opening above the metal neck, then embedded in a plastic end overmolded above and around the metal neck.
- the production of such a tube therefore requires at least three separate operations: threading the inner tube into the outer tube, flaring the projecting end of the neck of the inner tube and then gently overmolding a plastic crown. on the edge of the metallic external neck.
- Patent application J07277349 describes a double-walled tube also made up of two tubes produced separately but linked to each other at their necks by means of a nozzle which is force-fitted around the assembly.
- the top end of the neck of the internal tube largely exceeds the top end of the neck of the external metal tube.
- the projecting part is flared and then folded outwards, covering the external metal neck.
- the end piece is forced into place and rests on the outside of the folded part of the inner tube.
- J07277349 recommends that the internal tube, which is made of plastic, has at least at its ends a smooth wall, free from mold seal lines. Such a smooth wall is obtained by injection molding the internal tube.
- the end of the neck of the internal plastic tube must be fairly thin, which gives it poor buckling resistance and does not not facilitate the first shaping step which consists in flaring the end of this neck. This necessary step is complicated by the need to design a tool which perfectly maintains this neck during flaring.
- injection molding does not allow an easy realization thin neck made of a plastic material resistant to cracking under stress. Indeed, these tubes require the use of materials suitable for injection over a long length in a narrow air gap. Such materials must have a high melt index, greater than 15, and are much more sensitive to stress cracking in contact with the contained product than the materials usually used, with a lower melt index (0.2 to 2).
- the internal plastic envelope by other more economical means, for example blow-molding extrusion or even molding of a head on an extruded or laminated welded skirt.
- blow-molding extrusion or even molding of a head on an extruded or laminated welded skirt.
- the Applicant has therefore sought to economically produce a double-walled tube with a flexible and protective internal envelope and a metallic external envelope, intended for storing and distributing products which are aggressive with respect to the metallic envelope, the two envelopes being linked between them by their ends, the connection at the level of the necks having improved sealing, in particular for very long tubes.
- a first object of the invention relates to a double-walled tube comprising an internal tube having a skirt, a shoulder and a neck, subsequently called an internal neck, delimiting an orifice, subsequently called an internal orifice, a metal tube having a skirt , a shoulder and a neck, later called a neck external, provided on its outer wall with latching means, the two tubes being interconnected at their necks by a nozzle having a bottom and at least one external skirt enclosing said two necks and provided with complementary latching means of latching means of the external neck, characterized in that the end piece is provided with an internal skirt, the external wall of which has a generally frustoconical profile, so that, when the end piece is forced in, said internal skirt imposes a circumferential expansion in the middle parts of the necks and a widening of the ends of said necks.
- the bottom of the endpiece When the endpiece is forced in, the bottom of the endpiece is not supported on the edges of the internal and external necks, that is to say that there is a non-zero clearance, greater than a few tenths of millimeter, between the bottom of the end piece and said sections.
- the part of the internal skirt of the endpiece which is introduced into the internal neck has, over a length at least equal to 2 millimeters, an external diameter greater than the initial diameter of the internal orifice.
- the internal tube may be of any flexible material capable of protecting the metallic external envelope of the corrosive conditioned product.
- an internal plastic tube will be chosen. It is obtained by any known means: injection molding, blow molding, molding of the head then welding of the latter on an extruded or laminated welded skirt.
- Its neck is devoid of intaglio or raised details but may include mold seal lines. It is thick enough to avoid any risk of buckling during the insertion of the nozzle on the necks.
- the geometry of this hollow cylindrical neck should preferably check a height to thickness ratio of less than 10, so as to avoid an "accordion" deformation of said neck.
- the outer tube is metallic. It has a skirt, a shoulder and a neck. Before the tip is inserted, the internal tube is threaded into the external tube.
- the outside diameter of the internal neck being substantially equal to or very slightly less than the inside diameter of the external neck, the two necks are find themselves very close to each other over a certain common height by their outer and inner walls respectively.
- the internal neck does not exceed or very little beyond the external neck: it is not essential to fold it over the end of the external neck.
- the end piece has an external appearance similar to the end pieces of the prior art, it can be provided with an external skirt fitted on its external wall with means of attachment with a plug, for example a thread. It is held firmly astride the external neck thanks to fixing means such as latching beads situated respectively on the external wall of the external neck and on the internal wall of the external skirt of the end piece.
- the outer skirt is provided on its outer wall with a thread and on its inner wall, already provided with a bead of 'snap, anti-rotation means, such as longitudinal fins.
- anti-rotation means also in the form of longitudinal fins with complementary sections, for example, located on the outer wall of the external neck.
- the endpiece is precentred, the precentring being facilitated by the presence of the internal skirt, and the fins are tapered at their upper ends as regards the fins of the external neck and at their lower ends as regards the fins of the outer skirt of the nozzle.
- the bottom of the end piece is at a distance from the latching bead, located on the inside wall of the external skirt of the end piece, such that, at the end of the insertion of the end piece, the inside wall of this end piece does not does not crush the flared ends of the necks.
- the bottom of the end piece does not bear on any of the edges of the necks.
- the internal skirt of the endpiece ⁇ has been forced into the internal orifice, the external diameter of the orthogonal sections of said internal skirt being, on a part in contact with the internal neck and of length at least equal to 2 millimeters, greater than the initial diameter of the internal orifice, that is to say the diameter of the internal orifice before the tip is pressed.
- This minimum length must be respected whatever the outside diameter of the neck envisaged, practically between 4 and 25 millimeters.
- the profile of the external wall of the internal skirt is generally frustoconical, the open end of the skirt being oriented towards the apex of the cone, so that, during its forced insertion inside the orifice internal, the internal skirt imposes a plastic deformation, resulting in a flaring, of the ends of the two necks.
- the internal skirt of the end piece therefore plays a dual role: it is first, during the forced insertion of the end piece, a tool which imposes a circumferential expansion on the middle parts of the necks, the internal neck, in direct contact with the skirt, being more stressed, and which then requires flaring of the ends of the necks. Finally, it is an effective sealing skirt throughout the use of the tube.
- the internal neck in direct contact with the internal skirt of the nozzle, undergoes a circumferential expansion deformation and its external wall is pressed against the internal wall of the external neck by transmitting radial forces oriented towards the outside, which ensures a contact between these two walls is all the more intimate as the external neck is less likely to deform, that is to say more rigid and harder, than the internal neck. It follows a perfectly sealed connection, even if the outer wall of the internal skirt is not perfectly smooth, for example due to the presence of a mold seal line.
- the internal skirt of the end piece is preferably thicker near its fasteners.
- a preferred embodiment of the invention consists in giving the inner skirt of the endpiece a cylindrical inner wall and an axisymmetric outer wall, of cylindro-bitronconic shape, the middle part being cylindrical, the other two frustoconical.
- the outer wall of the internal skirt of the endpiece comprises three parts of substantially equal dimensions which can be described starting from the bottom by:
- the end of the metallic external neck is deformed so that it comes to bear on the inner wall of the end piece.
- the contact between the two deformed neck ends is thus maintained between the bottom of the internal skirt and that of the external skirt of the end piece.
- the bottom of the latter is thick and its internal wall is smooth, of diameter substantially equal to the external diameter of the external neck increased by a value less than the difference between the diameter of the cylindrical part of the internal skirt of the nozzle and the initial diameter of the internal orifice.
- the internal neck is fairly thick, which makes it possible to reduce the influence of any local excess thickness of the external wall of the internal neck on the quality of the tightening and sealing.
- the tip according to the invention has the advantage of locating the sealed contact on the first diameter encountered by the product. There is no risk of product retention in peripheral areas more or less stressed during the use of the tube. On the other hand, intimate contact is located on the smallest diameter, which makes it possible to obtain a more intense and more effective tightening for a given diameter difference.
- the end piece is made of a harder and more rigid material than the material of the internal tube, which is also less hard and less rigid than that of the external tube.
- PP polypropylene
- PE.BD low density polyethylene
- the internal skirt of the endpiece must be thin enough to leave an orifice suitable for the flow rate of dispensing the product and thick enough to impose the desired deformations on the two necks, while mechanically resisting the forces which have been generated during sinking force of the tip and which persist, while relaxing, throughout the use of the tube.
- the skirt is preferably in continuity of material with the end piece, for example molded in rigid plastic, such as polypropylene.
- the outer aluminum tube is fully annealed after shaping, which gives it flexibility in its thin areas.
- the internal tube is made of a material as flexible and as hard as possible, resistant well to cracking under stress in the presence of an aggressive medium such as a hair dye. It is preferably made of a plastic material such as low density polyethylene.
- the Applicant has tested different geometries by varying in particular the diameters and the thicknesses of the necks and the skirts of the end piece.
- the best sealing conditions were obtained with a internal neck approximately as thick as the cylindrical part of the internal skirt of the nozzle.
- the external neck may be thinner than the other two, the metal being much more rigid.
- it can be further thinned down to typically half the thickness of the internal neck so that it flares plastically without great resistance, which facilitates the flaring of the internal neck, the latter remaining thicker than in the middle part.
- the internal neck is thus "pinched" in its middle part between a flared end which is not or little thinned and a non-deformed base, its trapping helping to firmly hold the internal tube inside the external tube.
- the deformation imposed by the internal skirt of the end piece corresponds to a tightening of 3 to 8%, preferably 4% to 6%, that is to say that the outside diameter of the part cylindrical of the internal skirt of the nozzle is greater, by about 5%, than the initial diameter of the internal orifice.
- a lower tightening does not give satisfactory sealing conditions throughout the life of the tube. Indeed, a certain loosening, more or less strong depending on the initial tightening is observed after a few weeks at room temperature.
- a greater tightening involves, during the insertion of the end piece on the necks, either an accordion-like deformation of the neck of the internal tube, or, if the thickness of the internal neck is significant, an insufficient depression making the assembly impossible.
- a second object of the invention relates to the end piece itself comprising a bottom and an external skirt provided with latching and anti-rotation means, characterized in that it comprises, also attached to its bottom, a skirt internal whose profile of the outer wall is generally frustoconical, the open end of the skirt being oriented towards the apex of the cone.
- this internal skirt is thicker near its attachment on the bottom of the end piece. It advantageously has a cylindrical inner wall and a cylindro-bitronconic outer wall, the frustoconical and cylindrical parts having approximately the same height, the frustoconical parts making a half ⁇ ngle at the top between 5 and 20 °.
- This tip is preferably made of a hard plastic material, such as polypropylene.
- FIG. 1 represents the axial section of a double-walled tube head according to the invention surmounted by the end piece before it is forced into the internal and external necks.
- FIG. 2 represents the double-walled tube head according to the invention after the tip has been forced into the necks.
- the left part is an axial half-section through a diametral plane passing a longitudinal fin of the end piece
- the right part is an axial half-section through a diametral plane passing through a longitudinal fin of the external neck.
- the double-walled tube 1 comprises an internal tube 10 and an external tube 20 made of annealed aluminum.
- the internal tube 10 is obtained by overmolding a head 12 in PE.BD (low density polyethylene) on a skirt 13, also in polyethylene, with a diameter of 24.3 mm and a thickness of 250 microns.
- PE.BD low density polyethylene
- the internal neck 11 defines an internal orifice 14. Its top end is the edge 18.
- the external annealed aluminum tube 20 has a skirt 25 with an external diameter of 25 mm and a thickness of 120 microns. It has a shoulder 24 and a neck 21, the top end of which is the edge 28.
- the external diameter of the internal neck 11 and the internal diameter of the external neck 21 are equal to 8.7 mm.
- the internal neck connected with a thickness of 0.75 millimeters.
- the external neck 21, with a thickness of 0.5 millimeters is provided, on its outer wall, with a snap rim 23 situated at the base of the neck and longitudinal fins 22 which extend along said outer wall up to 1 mm from the end.
- the inner tube 10 is introduced into the outer aluminum tube by conventional means: a mandrel threads inside the inner tube and drives it inside the outer tube, the shoulder and head of which are immobilized by a tool which follows its external shape.
- the edge 18 of the internal neck 11 exceeds the edge 28 of the external neck 21 by a few tenths of a millimeter.
- the external neck and the internal neck have a common contact height H of approximately 4.7 mm.
- the end piece 30 has an internal skirt 31, a bottom 34 and an external skirt 35 provided on its inner wall with fins 42 which are intended, in combination with the fins 22 of the external neck 20, to immobilize the end piece 30 in rotation. and, on its outer wall, with a thread 41, for the screwing of a capsule intended to plug the dispensing orifice 40.
- the cylindrical part 32 of the internal skirt 31 has a diameter of 7.5 mm, which imposes a tightening of 0.3 mm when the end piece 30 is pressed on the necks 11 and 21. The effect of a certain creep is felt after a few days, causing permanent deformation of the two necks and a reduction in the Tightening. The latter nevertheless remains greater than 0.1 mm.
- the internal skirt 31 of the end piece 30 has a cylindrical inner wall delimiting a circular distribution orifice 40 of 6.1 mm in diameter and an outer wall of cylindro-bitronconic shape, the truncated cones having their apices, that is to say ie the tops of the cones on which they rest, in the same direction as the open end 39 of the skirt 31.
- this wall is divided into three zones: - a central zone, 1.5 mm high, cylindrical and 0.75 mm thick, - a tapered, frustoconical zone, 1 mm high, widening to a diameter of 8 mm at the level of the fastener 33 on the bottom 34 of the end piece 30.
- the half-angle of the truncated cone is about 12 °.
- the external skirt 35 of the end piece 30 has on the side of its attachment a thick part 36, the smooth internal wall of which has a diameter of 9.8 mm does not abut against the anti-rotation fins 22 of the external neck .
- the fins 42 are introduced into the intervals left by the fins 22 of the external neck 21, the cylindrical part 32 of the internal skirt 31 of the end piece 30 imposes on the necks a expansion of 0.3 mm then the frusto-conical part 33 close to the attachment to the bottom 34 of the end piece 30 requires flaring at all of the ends of the necks 11 and 21.
- the outer skirt 35 of the end piece 30 is also provided towards its open end 20 with a latching bead 37.
- the position of this latching bead 37 relative to the bottom 34 of the end piece 30 is chosen so that that at the end of latching, there is no support of the internal face 38 of the bottom 34 of the end piece 30 on the flared top ends of the necks 11 and 21. This position is also such that the start of the flaring occurs before the start of the latching, which reduces the forces necessary for the insertion of the endpiece.
- Fifty double-walled tubes produced according to this method of the invention underwent this test, which consists of injecting air inside the tubes until an overpressure of 500 g / cm2 is obtained. These tubes are then closed and then immersed in water for 30 seconds. No leaks were W detected.
- the head and the skirt of the inner tube can be made of different materials, however compatible in fusion.
