Definitions
- the present invention relates to the packaging of objects or groups of objects by means of a packaging element with printed marking, the wall of which is made of plastic.
- the term "element" of packaging used here must be understood in its broadest acceptance, including in particular rigid or semi-rigid containers (bottles, shells, boxes) and flexible films, in particular heat-shrinkable films.
- the extensive development of distribution channels poses more and more problems for packaging professionals who must fight against the diversion of products, whether pharmaceuticals, perfumes, or food products in particular Large manufacturers Indeed, they often have exclusive distributors, and it appeared that certain distributors resold part of their stock at low prices, which allows a fraudulent reintroduction of products at low prices.
- Traceability is used to uniquely identify the individual product at several points, and considerably facilitates data management.
- fraudulent manipulations on the products make it necessary to provide markings, in particular codings, which must be as discreet as possible, in order to to preserve the traceability of the products, and thus to avoid any modification or destruction of packaging.
- We have thus developed different reading modes for example by interlaced bar codes ("two out of five") or other codes, or by electronic chips, which can be read by a suitable reading machine owned by the manufacturer or the distributor.
- these codes are generally easily spotted by counterfeiters, and as a result can be removed or torn off.
- the technical problem which the invention proposes to solve is to create a concept of marking on the plastic packaging element making it possible to avoid the identification of the code or codes used, in order to preserve them from destruction, while guaranteeing the identification and traceability of packaged products.
- document US-A-4 227 719 thus describes a copy protection technique, according to which an alert pattern is printed directly on the document and covered with a camouflage printed with an ink whose density is chosen below the critical threshold of the photocopier, so that any photocopy d protected document automatically displays the alert reason on the copy
- the object of the invention is therefore to produce a packaging element with printed marking, the wall of which is made of plastic material, either essentially transparent, or tinted in the mass, and the marking of which is not identifiable, while being able to be easily read by authorized persons with a suitable reading medium, which guarantees product identification and traceability
- the primary dispersing screen makes it possible to avoid the marking of the marking, even under low-light, and if the examination is carried out on the other side of the film, then the overprinting dispersing screen performs the same anti-tracking function.
- the packaging element according to the invention comprises on one face of said wall a marking printed with a sympathetic ink, said marking being sandwiched between said face on which said marking is printed, and a dispersing weft overprinting covering this marking and at least the area of said face which surrounds said marking, to make the latter undetectable
- the opacity of the tinted wall in the mass is sufficient to mask the marking, and if one examines said marking by the other face, the dispersing screen overprinting avoids the marking of the marking, even by examination under a grazing light.
- the or each dispersing frame has a speckled structure which takes up the structure used to print the marking. The structure then makes it possible to drown the area of the marking, reinforcing the invisibility.
- the or each dispersing screen will be chosen random, so as to avoid identification by fine analysis of the surface. It is also advantageous to provide that the marking printed with a sympathetic ink overlaps at least in part with the printed identification elements. on the same side This makes it easier to detect any intervention in the marking area, which would alter identification elements, rendering then the unsaleable product when it concerns for example legal notices indicating the origin, the name or the composition of the product.
- the sympathetic ink used for marking appears only under the action of a chemical reagent chosen to have an irreversible destructive action on the wall of the element. Indeed, any attempt to intervene in the marking area has the effect of irreversibly destroying the area of the wall, which is immediately identifiable even by a consumer of average attention. Protection can be further refined by providing that the chemical reagent is chosen to have a destructive action delayed on the wall of the element Indeed, the destructive action will only appear very after the intervention carried out by the counterfeiter
- the packaging element includes an additional marking readable under UV light, separate from the marking printed in sympathetic ink.
- the additional marking is printed on the face opposite to that which bears the marking. in sympathetic ink
- the face carrying the marking in sympathetic ink as well as the dispersing screen (s) is the internal face, that is to say the face which is turned towards the object or group of objects. to pack Indeed, this forces the counterfeiter to cut the wall surrounding the object or the group of packaged objects to intervene by trying to destroy the marking present on the internal face of said wall.
- the marking in sympathetic ink is a coding serving to guarantee the identification and the traceability of the object or group of packaged objects.
- coding must be taken here in its broadest sense, in accordance with the most modern possibilities of data encryption
- the wall of the plastic packaging element may be rigid or semi-rigid, and form a container, in particular a bottle, a shell (blister), or a box.
- the wall of the plastic packaging element may be flexible and to form a packaging film, in particular a heat-shrinkable and mono-oriented film. This is particularly advantageous when such a material is used. film to form heat shrinkable packaging sleeves
- the invention also intends to protect a heat-shrinkable packaging sleeve, which is produced from a section of heat-shrinkable and monooriented film having at least one of the aforementioned characteristics, film of which two end edges are sealed according to a sleeve generator
- the method comprises the following successive stages - printing on one face of the film of a primary dispersing screen, printing, on this primary screen, of an ink marking sympathetic, impression of a dispersing frame under pressure on the aforementioned marking
- the method comprises the following successive steps
- FIG. 1 schematically illustrates the method of obtaining a packaging element, here in the form of a film, the plastic wall of which is transparent and bears an invisible marking in sympathetic ink according to the invention
- FIG. 2 illustrates the same steps as in Figure 1, but in schematic sectional view
- - Figure 3 is a schematic view similar to that of Figure 2, in the case where a film is used whose plastic wall is mass dyed
- FIG. 4 illustrates different types of structures used to print the marking, and consequently used again to produce the speckled structure constituting the dispersing screen (s),
- FIG. 5 is a schematic view illustrating an installation implementing a fab ⁇ ca- tion method of a transparent wall packaging film and invisible marking in sympathetic ink according to the inven ⁇ , possibly with an additional marking readable under UV light,
- FIG. 6 is a perspective view of a heat shrinkable packaging sleeve made from a section of film of the aforementioned type, in accordance with the invention
- FIG. 1 there is a strip of plastic packaging film 10 whose wall is transparent here
- the upper face of this wall is denoted 11 and its lower face is denoted 12.
- the constituent material of this film could for example be chosen from the materials usually used in the packaging field, such as polyethylene, polystyrene, polyvinyl chloride, etc. It will generally be any rigid or semi-rigid plastic material making it possible to produce a box, a shell (blister), or a flexible film.
- the film 10 carries on its face 11 printed identification elements 13, here shown schematically by the letters A and B.
- the packaging film 10 is in this case transparent, so that the printed identification elements 13 are perfectly visible from the opposite face 12 which is for example the front of the film.
- a primary dispersing frame 14 is deposited which has a speckled and random structure.
- This primary screen 14 is for example printed by means of a screened coating cylinder, for example according to a gravure printing technique or any other technique of screen printing not necessarily using cylinders.
- the peripheral surface ⁇ that of the cylinder is then etched according to the desired pattern of the random speckled structure.
- a structure will be chosen which takes up the structure then used to print a marking in sympathetic ink, for example by using dots, crosses, lines, etc.
- a marking 15 is printed with a sympathetic ink.
- This marking is, for example, shown schematically here by a sequence of numbers 1,2,3,4.
- identifying elements may be the brand of the product, or visual elements such as those which are commonly used for example for the legal notices giving the origin or the composition of the product.
- visual elements such as those which are commonly used for example for the legal notices giving the origin or the composition of the product.
- the primary dispersing frame 14 is present over the entire area denoted 17 on the face 11 of the film which surrounds the marking 15.
- a disper ⁇ health frame 16 is superimposed overlaying the marking 15 and at least the aforementioned zone 17 which surrounds said marking, to make the latter undetectable.
- the marking 15 is thus sandwiched between the two dispersing frames 14,16
- step c the product obtained in step c
- step c the product obtained in step c
- the overprinting dispersing frame 16 also has a speckled structure which takes up the structure used to print the marking 15.
- a packaging film whose face 11 includes a marking 15 printed with a sympathetic ink, and, in overprint, a dispersing screen 16 covering this marking 15 and at least zone 17 of said face which surrounds said marking, to make the latter undetectable
- the film is transparent in zone 17 of its face which surrounds marking 15, and it comprises on said face a primary dispersing weft 14 on which the marking 15 is printed, the assembly being covered by the overprinting dispersing frame 16
- the marking 15 is therefore in this case sandwiched between the primary dispersing frame 14 and the overprinting dispersing frame 16
- the packaging film comprises a dispersing weft 16 superimposed which is unique, without primary dispersing weft
- the marking 15 is therefore in this case sandwiched between the face on which said marking is printed and the overprinting dispersing frame 16
- the marking 15 printed in sympathetic ink overlaps at least in part the printed identification elements 13 This naturally does not constitute an obligation, but further complicates the task of the counterfeiter by rendering practically impossible to preserve the identification elements during a destruction work carried out in the area of the printed marking
- the protection conferred is further improved if it is provided that the sympathetic ink used for marking 15 only appears under the action of a particular chemical reagent, which is chosen to have an irreversible destructive action on the film II may these are solvent-type developers, for example ketones or esters
- solvent-type developers for example ketones or esters
- the film wall then automatically shows traces of destruction that is irreversible, and therefore immediately identifiable later, even by a consumer of average attention.
- This security can be further refined by providing that the chemical reagent is chosen to have a delayed destructive action on the film. Indeed, the counterfeiter cannot foresee that the solvent will continue its action in the material of which the film is made, and cause irreve traces risk of destruction which will not appear until well after the intervention carried out on the marking
- FIG. 4 schematically illustrates the visual effect of the structures used to print the marking 15 and the dispersing screen (s) 14, 16.
- the printed marking 15, here symbolized by the number 1 is printed by successions of small dots. If the film 10 used is transparent, then the face concerned will have been previously coated with the primary dispersing frame 14, also produced with a structure speckled in small dots. As this structure is preferably random, visual identification, even by sophisticated analysis means, will be further complicated. In this case, the primary screen 14 has not been shown, in order to be able to distinguish the figure from the marking 15. After depositing the dispersing screen overprint 16, the cloud of small dots makes it completely impossible to locate the figure 1 previously printed in sympathetic ink, even with an examination in grazing light. In 2) and in 3), the same phenomenon is illustrated with respectively a structure using sequences of crosses, and sequences of lines. These are, of course, only examples, and any other kind of structure could be used with current printing means.
- the packaging film may also include an additional marking readable under ultraviolet (UV) light, which is separate from the marking 15 printed in sympathetic ink.
- This additional marking will preferably be printed on the face opposite to that which bears the marking 15 in sympathetic ink.
- the use of such additional marking further complicates the task of the counterfeiter, who must also intervene with an ad hoc reading to alter this marking. .
- it succeeds, by depositing a varnish or other adequate chemical, to drown the UV marking in an enlarged area making it impossible to recognize and read this marking there is still the marking printed in sympathetic ink which, meanwhile, cannot be detected thanks to the use of one or two dispersing frames
- FIG. 5 a method of manufacturing a packaging film in accordance with the invention has been illustrated. It is of course a schematic illustration, aiming only to explain the successive operations carried out on the film.
- the film 10, possibly previously printed, for example with its previously mentioned printing elements, is here of transparent type.
- the film 10 first arrives at a station 20 corresponding to the printing of the primary dispersing screen 14 For this, it passes between two rollers 21,22 of which the roller 21 is a screened cylinder, the screening of which is preferably chosen in accordance with the structure used for the subsequent printing of the marking. Although any color can be used, it is preferable to choose a gray or black color already used for printing the printing elements.
- the film 10 then arrives at a station 30 for printing the marking in sympathetic ink.
- the device used is shown diagrammatically in 31.11.
- the printing of the marking in sympathetic ink occurs here on the side 11 or back (V) of the film which is that already coated beforehand with the primary dispersing frame 14
- a device 32 used to print a UV marking here on the face 12 opposite to that carrying the marking prints in sympathetic ink, that is to say on the front (R) of the film.
- the film 10 finally passes at a station 40 for printing the overprinting dispersing screen 16.
- the film 10 thus passes between two rollers 41 and 42, the roller 41 of which is a screened cylinder analogous to cylinder 21. used at the level of station 20.
- This deposition of the dispersing frame 16 in overprinting is fundamental, because it is it which makes it possible to sandwich the marking produced in sympathetic ink, and thus to make said marking undetectable.
- the packaging film can be a heat-shrinkable and monoriented film. This is particularly advantageous when using such a film to conform heat-shrinkable packaging sleeves. Illustrated in Figure 6 such a heat shrinkable packaging sleeve which will now be described in more detail.
- a heat shrinkable sleeve 50 is thus distinguished, produced from a section of film 10 or 10 ′, coated with the abovementioned prints and screens, two end edges of which are sealed according to a generatrix of the sleeve, at the level of a sealing line denoted 51.
- a UV marking 18 On the outer face 12 of the sleeve, the presence of a UV marking 18 will be noted, here diagrammed by the figures 1,2,3,4.
- the film constituting the sleeve 50 bearing the marking in sympathetic ink 15 and the dispersing screens 14, 16 is entirely transparent. It goes without saying that it will be possible to provide that the face 11 of said sleeve. bearing the marking in sympathetic ink 15 and the single dispersing weft overprinted 16 is tinted in the mass, in which case only one dispersing screen is used (superimposed on the marking in sympathetic ink)
- the marking in sympathetic ink 15 will be a coding serving to guarantee the identification and the traceability of the object or group of objects packaged.
- the recipient has the ad hoc developer, and he knows the location of the coding printed in nice ink so it can easily read the coding
- the plastic packaging element is not a flexible film, but has a rigid or semi-rigid wall, forming a container, in particular a bottle. , a shell (in particular a blister) or a box
- a shell in particular a blister
- a box in particular a blister
- the invention is not limited to the embodiment which has just been described, but on the contrary encompasses any variant incorporating, with equivalent means, the essential characteristics set out above.
