Description

FLEXIBLE TUBE PROVIDED WITH ELECTRONIC COMPONENT Field of the Invention The invention relates to flexible tubes of plastic material, more particularly for which logistic monitoring is desired, for them and / or for products that contain them. The invention finds an advantageous application not only in the logistic monitoring of these tubes before their delivery to packaging customers but also in the monitoring of the products that contain them, since the latter usually have a more important value than the tubes and that in fact they are exposed to acts of falsification.

BACKGROUND OF THE INVENTION Flexible tubes of plastic material may contain information introduced by the manufacturer of flexible tubes when manufacturing the aforementioned tube. Thus, application JP2003-165552 (LION Corp.) describes a flexible tube provided, near the final weld, a bar code or a decoration representing a registered trademark in order to detect the name of the product. If necessary, the information can be discrete, for example the printing can be done with the help of thermochromic or "safe" inks, only detectable by means of a REF. DO NOT. 172923 heating, ultraviolet radiation, etc. Such techniques require prior knowledge of information about the product at the time of manufacture of the tube. It is not possible to characterize a product designed to be packaged in a standard tube that can be used for other products. For example, if you want to make a decoration using UV inks, this can be done during the manufacture of the tube, or in the continuous band for laminated tubes, or in the extruded cylindrical body (plastic tubes) with conventional printing devices. But, once the tube is delivered to the packaging customer, the information can no longer be modified, unless it is equipped with expensive printing devices. In practice, it is difficult, even impossible, to provide complementary information, coded or not, on the tube once manufactured and delivered to the packer. A known technique that allows to overcome this problem consists of printing a label containing the desired information, coded or not, and placing it in an outer package that wraps the flexible tubes delivered to the packer (for example for the control of tubes), being directly in the skirt of the flexible tube (for example for monitoring the product contained in the tubes). But there is a major problem inherent in the use of a label: it can be removed very easily, and thus break the link that exists between the information that carries the product that is supposed to accompany. Patent application KR2003-025624 (ID TECK Co Ltd) describes a plug provided with a non-contact electronic circuit that allows, with the aid of remote reading and writing devices, to prevent falsification of the product contained in the container covered with this plug. Such a plug, due to its volume, seems unfit to cover a flexible tube that has a standard size (skirt diameter normally included between and 60 mm, neck diameter normally included between 5 and 15 mm). In addition, once the container is opened, the cap can be easily lost or changed. In this case, there is also the risk of losing the union between the information and the product to which it is associated. Patent EP 0 697 342 describes a flexible tube provided with an anti-theft device, consisting of a field passive disturbing element, interleaved in the layers of a layered structure introduced in the corresponding flexible tube (multilayer insert making a transition between the skirt and the shoulder, multilayer operculum, etc.). The German patent application DE 102 18 417 (TUBEX) describes a distributor provided with a flexible tube that has a hinge plug fixed at its top in a substantially irreversible way on the head of the tube, the corresponding distributor is provided with an electronic module, of transponder type or magnetic strip, normally placed with the help of a support that acts as a label, in an inaccessible place of his head. The applicant set out to propose a technical device that allows, on the one hand, to guarantee the monitoring of tube production, on the other hand, to offer packaging customers the possibility of giving reliable information after the tube has been manufactured. coded or not, on the product contained in the tube, whether or not this is provided with a hinge plug and without the risk of losing the corresponding information during the entire life of the tube.

BRIEF DESCRIPTION OF THE INVENTION A first object of the invention is a hose head of plastic material comprising a dispensing orifice delimited by an edge and a shoulder joining the corresponding edge with a flexible skirt, characterized in that it comprises in the mass of the plastic material constituting the corresponding head, a fixed electronic module intended to exchange, without electrical contact, information with a reading or reading / writing device external to the corresponding tube. The corresponding electronic component allows exchanging information with an external device such as those equipped with smart cards, for example, in particular electronic components of the RFID (Radio Frequency Identification) type, the description of which will be detailed below. This information can refer to the same tube or to the product contained in the tube. Since the component is fixed in the mass of the plastic material constituting the head, it can be used at an early stage of manufacturing and serve to monitor the manufacture of the tube, starting from the realization of the head, indicating for example the plastic materials used, the skirt structure used, the presence of specific additives in the material of the head or skirt, etc. Once the tube has been made and delivered to the packer, the electronic component can also be used to allow the traceability of the packaged product (origin of its components, manufacturing conditions, storage before the first opening, etc.). . It is also possible to provide autonomous electronic components for example provided with their own energy source and capable of performing activated functions from an information resulting from data processed by this same component. For example, this component could, based on the programmed or remotely controlled measurement of a parameter relative to the product or the container, activate the display of information about the corresponding product or the corresponding container on the outer wall of the packaging, for example with the help of a colored reagent or also a diode or liquid crystal display. The tube head has a dispensing orifice and a skirt, the dispensing orifice is delimited by an edge joined with the corresponding skirt by means of a shoulder. The corresponding edge may be provided on the cylindrical wall of a neck intended to receive a plug, the corresponding neck is joined to the skirt by means of a shoulder of generally conical shape. But, as in the application WO02 / O8079, the tube head can be disproportionate of a cylindrical neck, the dispensing orifice is placed for example at the base of a capsule located on the upper part of the corresponding tube and connected with a cap through a hinge. In such a case, the corresponding base joins the border that delimits the hole with the flexible skirt and also performs the function of a shoulder. The corresponding tube head comprises the corresponding electronic component, the latter being advantageously placed in the thickness of the shoulder or cap, when it exists. Preferably, the edge of the hole and the shoulder are made, at least in a portion of its thickness, in one piece by molding the same plastic material, and the electronic component is fixed in the mass of the corresponding plastic material. This allows, on the one hand, to make a shoulder with perfect continuity of matter between the skirt and the distribution orifice, in all or part of the. thickness of the corresponding shoulder and, on the other hand, simplify the manufacture: the production of an intermediate piece containing the component, its transfer, its union and then its welding with the rest of the tube is avoided. An RFID system comprises, on the one hand, a receiver transmitter, which controls the acquisition and data communication system, linked to an antenna and, on the other hand, a REID component that consists of a transponder attached to an antenna. The transponder is an electronically programmed radio-frequency identification tag to automatically emit a signal in response to the interrogation signal it receives. The antenna of the RFID component is a conductor attached to the label. It receives radio signals that activate the transponder to write or read data. The antenna can be presented in a variety of ways. In general, it is in the form of printed loops by screen printing with a conductive ink on a support of plastic material (usually an epoxy resin or a saturated polyester, for example polybutylene terephthalate), on which the transponder is also fixed. The turns can have a globally circular or polygonal shape, usually square or rectangular. In the latter case, when the length is notably greater than the width, the antenna has a global longilinear shape: we will call it "linear antenna" or "longline antenna". In general, the junctions between the transponder and antenna arms are protected by a layer of plastic material, usually an epoxy resin, which forms an extra thickness. Preferably, the corresponding electronic component is placed on the shoulder of the tube, in the mass of the plastic material constituting the head, in order to avoid contact of the antenna and label with the product that the tube is intended to contain. It is fixed in the mass, preferably without resorting to adhesive materials, for example during injection molding of the head. The conditions of adjustment of the component in the injection mold cavity depend on the chosen antenna shape. Some of these are described in the examples presented below.

Another object of the invention is a hose tube manufacturing method characterized in that an electronic module suitable for exchanging without electrical information contact is used with a reading or writing / reading device, usually an electronic component of the RFID type, because the corresponding electronic component (also called "chip") is placed inside the mold cavity intended to make the corresponding head, and because the corresponding head is molded, the plastic material flows blocking the chip, the head assembly and chip resulting indissociable. Preferably, an injection molding of plastic material in the corresponding mold cavity will be carried out. A compression molding can also be carried out if the electronic components used are strong enough to withstand the mechanical demands generated by this type of shaping. If such injection or compression molding is done, the component is placed in the mold cavity intended to make the corresponding head. The latter comprises at least two moving parts, one with respect to the other: the matrix, whose cavity defines the outer surface of the shoulder and neck, and the punch, whose head defines the inner surface of the shoulder and the neck. Many times, the neck has to present a screw thread on its outer wall, which imposes the use of a matrix that also comprises several moving parts that move away from each other, for example with the help of radial displacements, to facilitate the demolding of the threaded part. To avoid any risk of chemical incompatibility with the product intended to be packaged in the tube, it is desirable to fix this component without resorting to an adhesive. In this case, it is desirable to find a geometric chip configuration and a location in the mold cavity so that the corresponding chip does not tend to move or deform during molding. The examples given below show two embodiments in which the electronic component supports the plastic injection molding operation without sensitive displacement or deformation. Preferably, the corresponding electronic component is placed on the convex conical surface of the punch head, the molding device is positioned so that the punch is below the die. Thus, the electronic component can be carried over the punch head and placed by simple gravity. The plastic material used for the molding of the head is the plastic material that is usually used, namely normally high density polyethylene, low density or medium density. Preferably, the injection molding is done at a temperature comprised between 240 and 250 ° C. In order that the component is not in contact neither with the outside nor with the interior of the tube, a component having a total thickness (support + extra thickness formed by the protective layer of the welds) of less than 400 microns is chosen. Thus, it is not necessary to modify the usual shoulder thickness of a standard flexible tube. The electronic components that are usually proposed in commerce are made with epoxy-type thermosetting resin supports. They can have all possible measures. If the obligations regarding the scope of the reception of information are not very strict, it is possible to directly use commercial components that are not very bulky, which are "lost" in the mass of the plastic material injected. However, the precise adjustment of such bulky electronic components can pose a problem since care is taken to avoid the use of adhesive materials, which allows, for example, to fix the component at a precise place in the mold. This is the reason why it was advantageous to choose more bulky components, which thus benefit from a greater range of frequency reception. These electronic components must have a support able to withstand the mechanical and thermal demands generated by the plastic material in fusion during molding. The fixation of the component in the plastic material of the head can be purely mechanical: only try to place the periphery of the support in the plastic material overmolded around the corresponding component. The fixing of the electronic component can also be done by welding, in such a case, a support will be used that is constituted at least partially by a material compatible in fusion with the plastic material of the head, normally a high density polyethylene or polypropylene. Such material can cover the corresponding support in the form of an outer layer. This outer layer can cover the part of the antenna obtained by screen printing. It can also cover the other side of the support. Preferably, the component fits into the cavity of one of the molding tools, the corresponding outer layer of a plastic material compatible in fusion with the plastic material of the head is placed so as to be in contact with the engraved surface of the cavity of the molding tool. Thus, after molding, the outer layer results in contact with the product contained inside the flexible tube and offers a protective barrier for the electronic component. In a preferred embodiment, the electronic component has a support having one face of thermoplastic material, and the other face covered by the antenna and also covered, outside its periphery, by an adhesive material that allows it to adhere to a distribution band. Thus, before the molding, the component is carried by displacement from the band to the mold, and then released by simple peeling of the band perpendicular to the mold cavity, and low, by gravity or with the help of a suction cup for example, in the mold cavity, the face of thermoplastic material rests on the engraved surface of the mold. During molding, the plastic material in fusion covers the face comprising the antenna and the adhesive layer: since the corresponding adhesive material does not cover the periphery of the corresponding component, it is inserted in the head, intimately attached to the plastic material of the head. To guarantee a precise and repeatable adjustment of the corresponding component in the mold, without resorting to the use of adhesive materials, an electronic component is advantageously chosen in a perforated disc-shaped support at its center that is placed around the protrusion of the punch that serves to shape the inside of the neck. Another possibility, in particular when the electronic component does not have the shape of a perforated disk in its center, for example, can have the shape of an arc -which extends to 90 °, 120 ° or 180 °), which consists of O-groove, with an angular extension slightly superior to that of the component, in the upper part of the punch. Thus, the notch serves as a housing that guides and facilitates the adjustment and then helps maintain the component prior to the approach of the die prior to the molding operation. During the actual molding, the cavity formed by the notch facilitates the flow of the plastic material below the support of the component, which guarantees blocking of its periphery. Another object of the invention is a flexible tube comprising a head and a flexible skirt, characterized in that the head comprises, preferably on the shoulder, an electronic module suitable for exchanging information-free contact with a read or write / read device, normally an electronic component of the RFID (Radio Frequency Identification) type. The head is welded to the skirt either after its molding, or during molding. In the latter case, it is said that the head is overmoulded in the skirt: the calorific contribution from the plastic material injected is sufficient to melt the plastic material at the end of the skirt that is intended to be fixed on the corresponding head. To overmold the tube head in a skirt, the part of the mold called the punch is inserted into the corresponding skirt, enough so that one end of the skirt protrudes and is blocked in the mold cavity or bounded by the head of the punch and cavity of the matrix. The plastic material, under the effect of injection or under the effect of compression, comes in contact with the end of the skirt. At a temperature higher than their respective Vicat softening temperatures, the plastic materials of the head and the skirt are welded intimately to each other without any other contribution of heat or material. After a slight maintenance under pressure (in the order of a few seconds) and cooling, the head is molded to the desired measurements and welded firmly in the skirt. Another object of the invention is a method for manufacturing a flexible tube provided with a tube head, in which the head is overmolded at the end of the skirt, characterized in that an electronic module suitable for exchanging without electrical contact information with a device for reading or writing / reading, usually an electronic component of RFID type, is placed on the head of the punch, in abutment against the protruding skirt end in the mold cavity. In this embodiment of the invention, the protruding end of the skirt is used to "immobilize" the corresponding electronic component comprising a transponder and an antenna: this is placed on the head of the punch, against the end of the skirt. The electronic component can be a chip in a fairly heavy and rigid epoxy type support, so that the supply of chips can be done by simple stacking: a mold is carried perpendicularly to the stack, the chip located at the base of the stack is loose, falls by gravity in the mold cavity and comes to hit the end of the skirt. It is also possible to choose a linear antenna, preferably with a support of thermoplastic material. The chip is placed by means of an automated grasping device. It is flexible enough to follow, when placed, the curvature imposed by the skirt end. More preferably, a linear antenna is chosen the longest possible (with a length at least equal to half the diameter) to decrease the efforts and displacements engendered when the molten plastic material arrives. If necessary, the detection range of the antenna can be adjusted by increasing the number of turns. Figure 1 illustrates a band used to place at an accelerated rate long-line chips in the cavity of a device that allows to mold tube heads. Figure 2 illustrates an axial section of a part of this molding device: the mandrel is provided with a skirt before molding the head and a long-line chip was placed on the head of the mandrel.

Figure 3 illustrates an axonometric view, comprising a partial diametrical section, of the head of the tube overmolded into the skirt and comprising the longilinear chip in the thickness of the shoulder. Figure 4 illustrates a band used to place at an accelerated rate chips in the form of a perforated disk in the cavity of a device that allows to mold pipe heads. Figure 5 illustrates an axial section of this molding device: the mandrel is provided with a skirt before molding the head and a perforated disk-shaped chip was placed on the convex conical surface of the head of the mandrel. Figure 6 illustrates an axial section of the tube head overmolded into the skirt and comprising the disk-shaped chip pierced in the thickness of the shoulder.

Detailed Description of the Invention Example 1 - Overmoulded tube head in a skirt and provided with a long-line electronic component (Figures 1 to 3) In this example, the specific geometrical configuration imposed by the overmolding of the head on the skirt and for the end of the skirt to protrude through the mold cavity is advantageously used. This protruding skirt end is used as a stop that serves as support for the chip. Figure 1 illustrates a band 1 used to supply the long-line chips to the molding device. The band is made of high density polyethylene. The edges 2 and 3 are perforated to facilitate a regular advance. Its central part is provided with a large number of rectangular perforations 4 separating ligaments 5 in which long-line antennas were printed by serigraphy and in the center of which transponders were placed. The transponders are joined to the antennas by means of welds protected by protuberances 22. Once cut at their two ends 6 and 7, the ligament becomes a long-line electronic component 20 with a support -21 and a transponder slightly protected by a relief 22. The release of the residual stresses resulting from the cut causes the longilinear electronic component to spontaneously acquire a certain curvature that facilitates its placement in the mold cavity. Normally, for the longilinear chip, a length included between the quarter and three quarters of the perimeter of the skirt is chosen, preferably between 40 and 60%. Figure 2 illustrates an axial section of the mandrel 10 in which the longilinear chip 20 was placed. The mandrel has a cylindrical body 13 around which the skirt 30 is adjusted and a head comprising a protrusion 14 which serves to define the internal surface of the neck and a convex conical wall 11 which serves to define the internal surface of the shoulder of the tube. The longilinear chip 20 is placed near the peripheral shoulder 12 which, with the protruding end 31 of the skirt, defines an annular groove 15. This peripheral shoulder 12 corresponds to the extra thickness that exists at the junction between the head and the skirt. The longilinear chip 20 comes into contact with the inner wall of the skirt. During the injection, it comes to stick all its length against the protruding end of the skirt before it softens with heating. Figure 3 illustrates an axonometric view, comprising a partial diametrical section, of the head 40 of the tube. Presenting a neck 41 and a shoulder 42 that joins the corresponding neck with the skirt 30. In the extra thickness corresponding to the union between the head and the skirt, the longilinear chip 20 located in the thickness of the shoulder can be found.

Example 2 - Tube head provided with an electronic component in the form of a perforated disc In this example, the head can indifferently be molded separately or overmoulded in the skirt. Figure 4 illustrates a band 1 'used to supply the molding device with chips in the form of a perforated disc. The band is made of high density polyethylene. Its edges 2 'and 3' are perforated to facilitate a regular advance. Its central part is provided with a large number of antennas 23 'in a globally circular manner, printed by silkscreen and joined with transponders. The band 1 'is cut according to two circumferences 6' and 7 'surrounding the circular antenna. The electronic component 20 'in the form of a perforated disk thus obtained has a support 21' in which the antenna 23 'is printed and which comprises a transponder connected to the antenna by means of welds protected by a relief 22'. To obtain usable chips regardless of the size and shape of the tube (circular cylindrical skirt, elliptical, polygonal, etc.); the diameter of the inner cutting circumference is chosen to be greater than the largest of the standard diameters of the dispensing orifice, and the diameter of the outer cutting circumference is chosen to be less than the smaller of the standard inscribed diameters of the skirts flexible Also preferably, the transponder and its protective relief 22 'are placed closer to the inner cutting circumference 6' when the relief is placed upwards and inversely closer to the outer cutting circumference 7 'when the relief is placed downwards. Thus, the protective relief 22 'of the welding, which is not continuously in contact with the wall of the tool during molding, is conserved from demands, mechanical generated during the mutual approach of the two parts of the tool. Figure 5 illustrates an axial section of the mold, comprising the mandrel 10 and the die 16. The perforated disc-shaped chip 20 'was placed around the protrusion 14, on the convex frusto-conical face 11 of the head of the mandrel 10. It should be noted that after the approach of the die and the punch to form the mold cavity 17, the component should be supported within the corresponding cavity, taking a frusto-conical shape. This transformation can be translated into a narrowing of the part near the diameter and an expansion of the part near the external diameter. With a particularly rigid support, a thick layer of epoxy resin or even, as in the present case, a rather thick support of high density polyethylene, it is advantageous to provide radial notches, at least in the area close to the internal diameter, for that the parts thus isolated from each other can move freely, even if they have to partially overlap during the narrowing. If, as in variant 1 below, the support is still thin and flexible, the shape of the truncated cone can be made without deterioration: -in effect, undulations are created but these remain "lost" in the mass of the material plastic of the head. Figure 6 illustrates an axial section of the head of the tube 40 'overmoulded in the skirt. Presenting a neck 41 'and a shoulder 42' joining the corresponding neck with the skirt 30. The chip can be found in the form of a perforated disc 20 'blocked in the thickness of the shoulder.

Variant 1 of example 2: This variant refers to a mode of manufacture slightly different from the previous one. Instead of using the band of figure 4, a distribution band is used in which the components, already made and cut to the required size, are glued thanks to an adhesive layer that facilitates their detachment by simple peeling. In this case, the support can be thinner and made with an even more flexible material (low density polyethylene for example). The face that supports the antenna is covered by the aforementioned adhesive material but outside its periphery. Thus, before the molding, the component is brought to the mold by displacement of the distribution band, then released by simple peeling of the band perpendicular to the mold cavity, and low, by gravity or with the help of a suction cup for example , in the mold cavity, the face of thermoplastic material rests on the engraved surface of the mold. During molding, the plastic material in fusion covers the face comprising the antenna and the adhesive layer: since the periphery of the corresponding component is not covered by said adhesive material, it is inserted in the head intimately joined with the plastic material of the adhesive. head.

Variant 2 of Example 2: This other variant also refers to another mode of manufacture, different from the previous ones. Instead of using the components described in figure 4 or in the first variant, components or inserts are used which have to be inserted, for other reasons, into the tube head: for example, the monobloc inserts of PBT (polybutylene terephthalate) or of thermoformed multilayer materials that are placed on the shoulders to decrease the permeability of the head with respect to oxygen and water vapor. For example, a multilayer barrier, such as that described in EP-B-0 524 897, can serve as a support for the electronic component: the antenna is printed by screen printing on the face opposite that which is intended to be exposed in the inside of the tube, preferably the impression is made in the area destined to remain on the shoulder, the transponder is placed and the welds that connect the transponder with the antenna are made. Then the insert is made by thermoforming. Once manufactured, the inserts-chips are assembled and stacked. Thus, the supply of inserts-chips to the molding device of the tube heads can be done in the same way as for the barrier inserts: a mold is carried perpendicularly to the stack of inserts, the insert located at the base of the stack is loose and falls by gravity in the molding cavity. This technique is already well known and is applied to barrier inserts introduced into the heads of the tubes for toothpaste.

Advantages The manufacturing process includes the introduction of the electronic component in the stages carried out at an accelerated rate: it is not necessary to carry out the addition of the chips further. The introduction is done at a production rate compatible with industrial rhythms, since there are already devices for placing inserts, for example to place barrier inserts in tubes for toothpaste. The chip is immersed in the mass of the plastic material constituting the head of the tube: the component can be perfectly discreet and there is no problem of incompatibility with the product that has to be packaged. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.
