Description
PROCESS FOR MAI<;ING CARDBOARD HAVING SAFETY MEANS
The present patent of invention relates to a process to obtain a special cardboard with safety means, for pharmaceu-tical packages and others, and product obtained, said obtain-ing process and product obtained are studied in their very details, in order to characterize something truly new, prac-tical, functional and highly safe.
The present process to obtain a special cardboard with safety means, for pharmaceutical packages and others, and product obtained, belongs to the technical field of manufac ture of paper, cardboards and the like.
Currently, pharmaceutical industries have been facing a serious problem, which is the forgery of their packages, as well as their medicines.
As it is known, every medicine should be packaged, even those forged and, in this case, forgery goes through the creation or copy of a package.
Thus, the certified medicine industry (laboratories) has a true interest in guaranteeing the recognition of its le gitimate product, and, at the same time, making difficult or clear the presence of: a copy.
Medicine packages are most of the times comprised by several items that may be imitated in the forged product, and, in this manner, the commitment in order to avoid forgery should encompass several divisions involved in the production chain, that is, laboratories, package and raw material manu-facturers.
It is known that one of the most common items of the packages i.s the cartridge (cardboard box) which encases an other package (another item) with blisters, vials, envelopes, etc., said cartridges being manufactured from cardboard cel lulosic raw material, in a print shop (converter) that prints the medicine charac;teristic graphics, and also carries out the operations of cutting, wrinkling and gluing the printed material; afterwards the empty cartridge is sent to the labo-ratory to be used for packaging the medicine.
Thus, the applicant herein, being a traditional manufac-turer of raw materials for packages, in order to contribute to a conclusive solution for forgery problems, specially of medicine packages, researched, developed and rendered the present process feasible, which resulted in the attainment of a special cardboard., which safety means prevent, in an effi-cient, practical and functional manner, any forgery attempt of said medicine packages.
Thus, the applicant herein, as a manufacturer of such cellulosic raw matE~rial, through the attainment of its spe cial cardboard, intends to guarantee the legitimacy of the cartridges, adding safety means with breakthrough character-istics to its special cardboard, which are comprised by:
- single surface, easily recognized and difficult to reproduce - colored core, easily recognized and difficult to re-produce, noticed at the moment the package is opened.
The attached drawings illustrate, in figures 1 to 7, the process to obtain <~ multilayered cardboard with a couche co ver, currently used in the manufacture of cartridges for me dicine packages.
Cardboards currently used in cartridges manufacture are produced in equipment that form layers of cellulose fiber, as paper sheets, which are assembled when wet, in order to form the multilayered final structure, the paper being formed from a dispersion of cellulose fibers in water, which is evenly poured on a moving mesh 1, so as to water is filtered by said mesh and fibers are piled up, forming a continuous sheet, as illustrated in Figure 1, which comprises a mesh scheme, where the paper sheet is formed. In this mesh scheme shown in Fig-J
ure l, it is provided, in addition to mesh 1, mass supplying set 2; headbox 3, l:ip 4, composition table 5, "hydrofoils" 6, suction boxes 7 and drainage rolls 8, paper improving cylin-der 9, suction 10, handle 11, mesh 12 and top 13.
Furthermore, after the first drainage over mesh 1, shee ~
14 is pressed in order to lose more water, and, in Figure 2, a paper machine presses scheme is shown, where top 15, bottom 16 and felt 17 rolls of the first press and top 18, bottom 19, guide roll 20 and felt 21 rolls of the second press are provided.
Afterwards, when water drainage by mechanical means be-comes too difficult, said sheet 14 begins to lose moisture by heat, through contact with heated cylinders 22, as shown in Figure 3referring to a paper machine dryers scheme, being also provided rolls 23 of felt drying and ventilation.
After drying, sheet 14 is wound over a winding cylinder 24 (Figure 4), andL then forwarded to the finishing phases, such as cut in smaller reels or flat sheets of several shapes.
On the other hand, during the formation process of sheet 14, it i.s possible to add other layers 25, formed in similar meshes 26, in order to create a multiple sheet, which is the cardboard 27 itsel:E, the scheme of forming meshes of a card-board machine being shown in Figure 5, while cardboard 27 structure scheme is shown in Figure 6:
Moreover, a lattices and mineral pigment-based paint cover 28 (couch paint) is applied to the multilayered sheet or cardboard 27, in order to improve the surface of said cardboard and allow better printing results, being that said application may be carried out in one or more layers. In Fig-ure 7; a scheme of the application of couche paint is shown, in which an immerging cylinder 29, an application cylinder 30, a paint reservoir 31, a deflecting and recovering system 32, a gas chamber 33, a blowing lip 34, a top cylinder 35 and a suction belt 36 acre provided. Thus, the description of the process to obtain the cardboards currently used in the manu-facture of cartridges is completed.
The process to obtain a special cardboard with safety means, for pharmaceutical packages and others, and product obtained, as illustrated in Figures 8 to 10 of the attached drawings, is characterized in that the multilayered cardboard 27 is provided with safety means, which initially comprise a single surface 37, being easy to recognize and difficult to reproduce, because, when white cellulose fibers 38 are mixed, being provided several synthetic fibers 39 having one or more colors, or treated so as to make them hardly visible to a na-ked eye, but evident under special lightning, such as exem-plified, but not limited to ultraviolet (Figure 8), said sin-gle surface 37 being the external layer opposed to layer 40 which will be printed (printing is carried out over couch paint 28), that is, the layer facing the inside of the fin-fished cartridge. In the composition of single surface 37, a special pigment may be added, which will become active, and absolutely perceptible when single surface 37 receives a sol-vent.
Moreover, multilayered cardboard 27 safety means are also characterized in that a colored core 41 is provided, be ing easy to recognize and difficult to reproduce, in contrast with the other white cellulose layers 42 (Figure 9), the core being generally a:ny layer or the internal cellulose layers set of cardboard 27, and since it is not accessible in any phase of cartridge: production, colored core may not be coun-terfeited or modified in any manner in its whole extension, because the accesa to it may only be possible upon the rup-ture or destruction of the external layers.
Finally, the product obtained comprises a special card-board provided with safety means, initially comprising a sin-gle surface 37, being easy to recognize and difficult to re-produce, since, wlhe~n white cellulose fibers 38 are mixed, 5 there are provided several synthetic fibers 39 having one or more colors, said single surface being the only external layer facing the inside of the finished cartridge and, fur-ther, said safety means comprising a colored core 41, which is easy to recognizE~ and difficult to reproduce, in contrast with the other white cellulose layers 42, the core being gen-erally any or the internal cellulose layers set of cardboard 27 (Figure 10).
With the special cardboard so obtained, said special cardboard, through its safety means, allows the medicine package cartridges t:o be easily and safely identified, assur ing the legitimacy thereof in the following ways:
a) The user, when. opening a medicine package cartridge, will recagnize the legitimacy thereof, by checking whether its internal surface, opposed to the printed external sur-face, is provided with several synthetic fibers of one or more colors, mixed to the white cellulose fibers. Thus, the confirmation of th.e presence of such synthetic fibers in the internal surface of the cartridge is the guarantee of the le-gitimacy thereof.
b) Likewise, t:he user, when opening a medicine package cartridge, will recognize the legitimacy thereof, by checking the presence of the colored core. In order to do so, the col-ored core may be disclosed through some special cut in the cartridge, that exposes said core when it is opened, or in a less autamatic manner, by a tear in any part of the car-tridge.
Thus, with the development of the special cardboard with safety means concerned, which simply, acurately and safely guarantees the legitimacy of medicine package cartridges, the applicant herein contributes in a crucial manner for the so-lution of the forgery problem of said cartridges.
