Definitions
- the invention relates to a method of manufacturing flexible tubes typically intended for storing and distributing liquid to pasty products containing perfumes, aromas or being sensitive to oxidation.
- Flexible tubes were previously metallic or metalloplastic and had, due to the presence of a metallic layer, a perfect barrier property to vapor, aromas and various gases (in particular oxygen).
- plastic or metalloplastic tubes are preferably done by injection of a plastic head then welding - possibly simultaneous - of said plastic head on a cylindrical skirt, obtained by cutting to a given length of a sleeve, said sleeve being itself obtained by extrusion - or coextrusion if it is multilayer - (extruded skirt) or by welding the side edges of a rolled strip so that said side edges are brought to face of each other ( laminated skirt).
- Laminated structures consisting of several coextruded layers comprising at least one layer with diffusion barrier effect, made of a plastic material such as EVOH (ethylene-vinyl alcohol copolymer), certain polyamides (PA) or modified polyamides.
- EVOH ethylene-vinyl alcohol copolymer
- PA polyamides
- the layer of EVOH is an intermediate layer between two layers of polyolefins, themselves being able to be a superposition of sublayers of low density polyethylene, of linear low density polyethylene and / or of high density polyethylene, each layer being connected over its entire surface to the EVOH layer by means of layers of adhesive material of EAA (ethylene-acrylic acid copolymer) or EMA (ethylene-methacrylic acid copolymer) type.
- EAA ethylene-acrylic acid copolymer
- EMA ethylene-methacrylic acid copolymer
- the tube head welded to the flexible skirt, has a dispensing neck and a shoulder which connects the neck to the skirt.
- the dispensing orifice is plugged, for example, by screwing a closure cap onto the neck (capping) and the skirt + plugged head assembly is delivered to the conditioners.
- This set is then presented upside down so that the conditioner can fill it with the open end of the skirt. After filling, said end which remains open is finally welded and the tube, delivered commercially, must be able to preserve the quality of the product it contains during several months of storage. If the level of losses is low since the appearance of fully plastic skirts whose structure is comparable to that described above, there is always the problem of losses of aroma at the level of the head, this being generally carried out by molding a polyolefin. Three groups of solutions have been proposed in response to this problem.
- a first group of solutions consists in adding a metalloplastic or plastic insert forming a diffusion barrier at the neck and at the shoulder.
- this insert is placed inside the tube, at the shoulder and the neck. It can be molded from a single material, preferably PBT (polybutylene terephthalate), or have several layers.
- PBT polybutylene terephthalate
- such an insert is produced by thermoforming from a laminate having a structure comparable to that of the multi-layer skirt described above, that is to say polyolefin (s) - adhesive layer -EVOH - adhesive layer - polyolefin (s).
- a second solution is to completely change the way of making the head.
- the applicant proposes to shape the head by heat-shrinking one end of the skirt made up of a laminate having a barrier effect layer. The constriction is carried out by formation between dies of crumpling plies, crushing of these plies then overmolding of the shoulder and the blank of neck thus produced with a polyolefin so as to obtain the final shape of the head.
- a third solution consists in producing the head in a polyolefin - EVOH - polyolefin multilayer by co-injection, as described in international application WO99 / 02525 presented by the applicant.
- the barrier layer For the head as for the skirt, it is recommended to place the barrier layer in the middle of the multilayer, a minimum thickness of the internal layers, typically made of polyethylene (PE), being intended to protect the barrier layer from the product contained in the tube.
- PE polyethylene
- this product, toothpaste or cosmetic, food product, etc. generally consisting of a large amount of water and the EVOH, particularly sensitive to moisture, loses, in the event of contamination, a large part of its barrier properties.
- the EVOH layer must be thick enough to have effective barrier properties but it must not be too thick compared to the other layers: the EVOH is particularly rigid and elastic, which degrades the "dead fold" property of the multilayer obtained.
- the object of the invention is to define a method making it possible, for laminated tubes as for extruded tubes, to obtain a head structure and a skirt structure free from a barrier material such as EVOH, which is rigid and difficult to co-inject with the polyolefins and which has, in the absence of an insert and for the same total thickness of the skirt - typically 250 - 500 microns - barrier properties and crushability at least as good as those of the structure of the prior art, the barrier properties must also be substantially uniform over the entire periphery of the skirt, even for laminated tubes (which have a longitudinal weld).
- a first object of the invention is a flexible tube provided with a skirt and a head, intended for storing and distributing liquid to pasty products containing perfumes, aromas or sensitive to oxidation, characterized in that said tube carries on the entire surface of its wall, that is to say on the surface of the neck, the shoulder and the skirt, a coating comprising at least one layer of thickness between 150 and 1500 ⁇ a material or a mixture of materials belonging to the following group: amorphous carbon, hydrogenated or not, nitrogenous or not, oxides, nitrides or carbides or their mixture or combination of one or more of the following metals (Si, Mg, Al , Ti, Zr, Nb, Ta, Mo, W, V).
- amorphous carbon hydrogenated or not, nitrogenous or not
- amorphous carbon is meant a material with a polymer tendency, characterized by a network of amorphous carbon chains capable of comprising hydrogen or nitrogen bonds.
- the wall of the flexible tube according to the invention is free from one of these polymeric layers with barrier properties described above, rigid and difficult to inject.
- the coating even if its thickness is limited to that of the layer according to the invention, gives the structure of the wall of the tube satisfactory barrier properties.
- the thickness of the coating is variable depending on the material chosen. It is limited so that the deposited layer remains flexible relative to its substrate and thus retains perfect mechanical strength during handling of the skirt. It must be thick enough to give the structure barrier properties that translate to • oxygen, with a permeability of less than 1 ml / m 2 / day / atmosphere (standard ASTMD3985)
- the wall of the flexible tube according to the invention comprises, at the level of the head as well as that of the skirt, at least one thermoplastic material such as a polyolefin, a polyester of the polyethylene terephthalate (PET) type or a copolyester.
- a thermoplastic material such as a polyolefin, a polyester of the polyethylene terephthalate (PET) type or a copolyester.
- PET polyethylene terephthalate
- said thermoplastic material composes the wall of the tube which serves as a substrate for the deposit.
- at least one layer of the structure of the skirt comprises a polymer loaded with a pulverulent material such as calcium carbonate or mica.
- the coating covers the internal surface of the wall of the tube, which protects it from the risk of scratches or flaking due to impacts on the external surface and on the other hand preserves all the possibilities of deposition. varnish or decoration printing on said external surface.
- Another object of the invention is an additional step in the process of manufacturing flexible plastic tubes in which the surface of the tube is coated - after assembly, typically by welding, of the head on the skirt - by carrying out a deposition assisted by plasma with a layer thickness between 150 and 1,500 ⁇ of a material or mixture of materials belonging to the following group: amorphous carbon, hydrogenated or not, nitrogenous or not, oxides, nitrides or carbides or their mixture or a combination of one or more of the following metals (Si, Mg, Al, Ti, Zr, Nb, Ta, Mo, W, V).
- a material or mixture of materials belonging to the following group: amorphous carbon, hydrogenated or not, nitrogenous or not, oxides, nitrides or carbides or their mixture or a combination of one or more of the following metals (Si, Mg, Al, Ti, Zr, Nb, Ta, Mo, W, V).
- the deposition can be carried out both on the external surface and on the internal surface of the flexible plastic tube.
- the examples which follow will illustrate, unless otherwise specified, deposits of internal coatings and can be easily transposed to deposits of external coatings.
- this deposition is carried out on the surface of the tube, at a speed compatible with industrial production rates, typically of one or more hundreds of tubes per minute.
- this deposition is carried out using a plasma surface treatment reactor.
- the plasma can be generated under different types of discharges: arc, luminescent discharge, discharge through a dielectric barrier or corona type discharge with different types of excitation: microwave, radio frequency, medium frequency alternating current.
- the last two types of plasma generation have the advantage of being able to be carried out under a pressure close to atmospheric pressure.
- the coating is obtained by condensation after decomposition of a body or a gaseous compound and the plasma can be generated • - either by low, medium or high frequency excitation or even by microwave.
- the working pressure can vary between one hundredth and one thousandth of a torr, • either again by dielectric barrier discharge or corona type discharge.

- the batch treatment is preferably carried out in a vacuum enclosure inside which the desired quantity of tubes to be treated is introduced, the latter being at this stage in the form of a head comprising a neck and a shoulder, said head being assembled with a flexible skirt.
- a set of cylindrical electrodes is introduced through the open end of the skirt comprising an external electrode surrounding the skirt of the tube and an internal electrode entering inside the tube over the height of the skirt and the precursor gas is injected through the said open end so that the plasma can move towards the shoulder and the neck.
- the deposition can be done downstream of the plasma formation zone and its thickness is all the more important as the part concerned is near the skirt, which is indeed the aim. referred.
- By varying the flow rate of the precursor gas and the plasma excitation parameters it is possible to extend more or less the area where the plasma remains active to assist the deposition.
- the plasma When working under a pressure close to atmospheric pressure, the plasma can be generated
- the deposition carried out under a pressure close to atmospheric pressure and assisted by a plasma generated by barrier or corona discharge can be integrated into the production line, just after the welding of the head on the skirt but preferably before the installation of the closure cap on the neck: the flexible tube has at this stage its two open ends and thus presents a configuration favorable to the free circulation of the precursor gas, which can easily pass through the internal volume of the tube from one end to the other .
- the device making it possible to generate the plasma by barrier discharge may comprise a set of internal and external electrodes similar to that described in the previous example (relating to the generation of plasma under low working pressure).
- a device with two electrodes having an axial symmetry is also used, the axes of symmetry of the flexible tube and of the electrodes being placed in coincidence.
- the internal electrode has axial convexities, revealing longitudinal edges in the shape of knives oriented radially and its envelope surface follows with a deviation of a few millimeters (typically 3) the shape of the internal surface (skirt + shoulder + neck) of the tube. flexible.
- the relative rotational movement of the internal electrode and of the flexible tube makes it possible to avoid peak effects which can lead to the appearance of areas of degraded appearance.

- axisymmetric electrodes placed on either side of the flexible tube are not used but a set of external electrodes, one placed facing an open end of the flexible tube and the other, coated in a dielectric, substantially matching, with a substantially constant offset, the shape of the generator of the flexible tube.
- the tube is rotated so that its wall runs opposite the side electrode and the deposition can thus be carried out over the entire circumference.
- the tube can indeed be treated provided with its closure cap because the plasma is confined in a bead of controlled size and it is not necessary to provide an opening at each end of the tube to facilitate the circulation of the plasma.
- the aim is a deposit thickness between 1 50 ⁇ and 1500 ⁇ , preferably less than 300 ⁇ .
- the material to be deposited can be any material having good barrier properties to the diffusion of aromas and gases.
- the carbon with polymer tendency is chosen, that is to say comprising a network of amorphous carbon chains with hydrogen, silica or alumina bonds.

- the hydrogenated amorphous carbon located in an underlayer, ensures a better bond on the polymeric substrate, typically polyethylene, of the flexible tube and ensures a more great flexibility in the coating obtained.
- the silica layer completes the barrier effect of the carbon layer while limiting the coloring due to carbon.
- the external coating thus obtained comprising a large proportion of silica on the surface, is better suited to the conditions imposed for the subsequent printing of the tube skirt.
- the aim is a deposit thickness of between 1 50 ⁇ and 1 500 ⁇ , preferably 200 200 500 ⁇ .
- 100 A / s as an order of magnitude for the deposition rate. This is around 50 A / s when cold plasma is used (corona or dielectric type discharge); on the other hand, it can exceed 300 A / s with a plasma type thermal plasma.
- the duration of the deposit can be limited to a few seconds, or even a few tenths of seconds.
- the pumping time must be taken into account to obtain the desired vacuum.
- “roots” type pumps are used.
- the working pressure of the deposit is between 50 and 1000 Pa.

- a preliminary sweep is carried out with an inert gas, of the argon type, to avoid the formation of impurities (risk of reaction with nitrogen in the air, water vapor, etc.) liable to deteriorate the quality. of the adhesion of the layer thus deposited.
- the fact of being able to work under a pressure close to atmospheric pressure makes it possible to envisage the economically satisfactory use of non-static devices, such as means for rotating the tube, which makes it possible to simplify the electrodes and to regularize the stability. plasma by confining it in the form of a cord.
- Figure 1 shows schematically in axial section (la) and in orthogonal section (1b) a first device intended to implement the method according to the invention by generation of a plasma under low pressure.
- FIG. 2 shows in axial section (2a) and in orthogonal section (2b) a second device intended to implement the method according to the invention using a means for generating a confined plasma in the form of a bead.
- FIG. 3 represents in axial section (3a) and in orthogonal section (3b) a third device intended to implement the method according to the invention by generation of a plasma by corona type discharge.
- Example 1 Deposition assisted by plasma under low pressure on the interior surface of the wall of a flexible tube ( Figures la and 1b).
- the flexible tube comprising a skirt 1 and a head 2, with a substantially cylindrical neck 3 and a shoulder 4, is placed in a vacuum enclosure, and rests on a plate, the skirt being framed by two coaxial cylindrical electrodes 11 and 12 , the axis of the tube and the axis of the electrodes coinciding.
- the external electrode 11 surrounds the skirt 1 up to the level of the shoulder.
- the internal electrode 12 entering the interior of the tube has a height slightly less than that of the skirt.
- An argon - acetylene mixture is introduced with a C2H2 / Ar ratio of the order of 10% is injected through the orifices 13.
- the pressure during deposition is of the order of 0.25 torr.
- the external electrode 11 is brought to ground while the internal electrode 12 is brought to a voltage of the order of 20 kV, pulsed at a frequency of the order of 250 kHz. Under the effect of the flow supply of precursor gas, the plasma is drawn towards the shoulder and the neck. Thus, the deposition can be done downstream of the plasma formation zone.
- the tube is in the state in which it usually leaves the production line, that is to say already equipped with its closure cap.
- An orifice 14 (in dashed lines in FIG. 1 a) is made in the support.
- the internal cylindrical electrode is surmounted by a shoulder "parallel" to the shoulder of the tube, which remains at a constant distance from said wall.
- the external electrode 11 while remaining cylindrical, has a slightly greater height than in the previous example.
- Example 3 Deposition assisted by plasma under pressure close to atmospheric pressure of a layer of silica on the inner surface of a flexible tube ( Figures 2a and 2b).
- the device used in this example uses a mode for generating a confined plasma in the form of a determined length of cord adapted from that disclosed in FIG. 10 and in Example 3 of application WO 99/46964 so that the plasma cord follows the shape of the generator of the flexible tube.
- axisymmetric electrodes placed on either side of the flexible tube are not used, but a set of external electrodes, one placed opposite the open end of the flexible tube and the other 21b, substantially matching, with a more or less constant difference, the shape of the generator of the flexible tube.
- the tube is rotated (R) so that its wall runs with regard to the lateral electrode and the deposition can thus be carried out over the entire circumference.
- the treatment could be carried out on the tube alone, before or after the tip of the head is cored (see following example). In the present case, it is carried out at the very end of the manufacturing cycle, after the head has been welded to the skirt and after the closure cap 10 has been placed on the neck 3.
- the tube can thus be treated provided with its closure cap because the plasma is confined in a bead of controlled size and it is not necessary to provide an opening at each end of the tube to facilitate the circulation of the plasma.
- the lateral electrode 21b and its insulating envelope 22 has a configuration close to that presented in FIGS. 10a and 10e of WO99 / 46964.
- a pulsed current is used, each pulsed discharge having the effect of treating a part of the internal surface of the tube in the form of a strip of determined width, depending in particular on the speed of rotation of the tube.
- Such a procedure which makes it possible to treat the entire surface by making an appropriate offset of these strips, has the advantage of limiting overheating since the plastic material of the tube has time to cool between two pulses: this time is all the more more important than dealing with nonadjacent bands.
- Example 4 Deposition assisted by plasma under pressure close to atmospheric pressure of a mixed layer of silica and carbon with a polymer tendency on the inner surface of a flexible tube ( Figures 3a and 3b).
- the system is arranged so that the tube leaves the conventional production line while the head is not yet cored.
- the end 7 of the injection core 5 is used to hold and drive the rotating tube (R). Vents 6 are provided in the core 5 to allow the circulation of the plasma in the direction of the neck.
- the tube is introduced into the cavity of the external electrode 31, the internal surface of which matches the external shape of the tube.
- An internal electrode 32 is inserted through the open end of the flexible tube inside it and the latter is rotated by means of the end 7 of the core around the internal electrode 32
- the internal electrode 32 has axial convexities, revealing longitudinal edges 33 in the form of radially oriented knives.
- the envelope surface of said electrode conforms with a difference of 3 millimeters to the shape of the internal surface (skirt 1 + shoulder 4 + neck 3) of the flexible tube.
- the relative rotational movement of the internal electrode and of the flexible tube makes it possible to avoid peak effects which can lead to the appearance of areas of degraded appearance.
- the external electrode 31 is brought to ground and a twenty kV is applied to the internal electrode 32.
- the gas an acetylene-HMDSO-argon mixture, the flow rate of which corresponds respectively to 20 sccm, 10 sccm and 15 sccm (sccm being a unit meaning standard cm3 per minute) is injected (P) through the open end of the flexible tube. It circulates between the internal electrode 32 and the internal wall of the flexible tube and is discharged through the vents 6 formed in the core 5.
- the plasma is generated between the edges of the electrode and the internal wall of the tube using an excited source at a frequency of 250 kHz.
- the tube is rotated for the duration of the treatment. A few seconds are enough to obtain a regular deposit of around 250 ⁇ .
- the coating is a mixed deposit of silica and carbon with a polymer tendency.
- the deposit is thin and deformable: the barrier properties are maintained even after extensive use of the flexible tube. • this process is also applicable to tubes obtained by injection molding in one piece.
