Oblasť technikyTechnical field
Vynález sa týka povrstvenej hliníkovej fólie so zlepšenými vlastnosťami pri tvarovaní za studená a obalu, predovšetkým pretlačovacieho alebo pľuzgierového obalu, vyrobeného s použitím tejto hliníkovej fólie.The invention relates to a coated aluminum foil with improved cold forming properties and to a packaging, in particular an extrusion or blister packaging made using this aluminum foil.

Doterajší stav technikyBACKGROUND OF THE INVENTION
Pretlačovacie alebo pľuzgierové obaly pozostávajú všeobecne z nosného telesa z plochého materiálu, v ktoréto rovnej ploche je tvarovaním tohto materiálu vytvorená množina priehlbín na uloženie baleného tovaru, predovšetkým tabliet, kapslí a podobne. Nosné teleso je na tejto rovnej ploche plošne spojené s hliníkovou uzavieracou fóliou. Materiál nosného telesa je pritom v mnohých prípadoch tvorený umelohmotnou fóliou, napríklad polyvinylchloridovou fóliou o hrúbke v rozsahu približne 0,2 až 0,3 mm, v ktorej sú tvarovaním za tepla vytvorené uvedené priehlbiny. Tlakom na zadnú stranu tejto priehlbiny v nosnom telese sa táto priehlbina deformuje a v nej uložená tableta alebo kapsľa sa môže po pretrhnutí uzavieracej fólie vyňať. Inou možnosťou je odtrhnutie uzavieracej fólie.The extrusion or blister packs generally comprise a support body of a flat material, in which flat surface a plurality of depressions are formed by the shaping of the material for receiving the packaged goods, in particular tablets, capsules and the like. On this flat surface, the support body is flatly connected to the aluminum sealing foil. The carrier body material is in many cases formed of a plastic film, for example a polyvinyl chloride film having a thickness in the range of about 0.2 to 0.3 mm, in which the said recesses are formed by thermoforming. By pressing on the back of the recess in the support body, the recess deforms and the tablet or capsule contained therein can be removed after the sealing film has ruptured. Another possibility is to tear off the sealing film.
Na predĺženie doby použiteľnosti sa teraz u mnohých liekov požaduje, aby obal bol, pokiaľ je to možné, plynotesný. Toto je však u bežných pretlačovacích, poprípade pľuzgierových obalov možné len v obmedzenom rozsahu, pretože plyny, poprípade vodná para, môžu difúziou prenikať cez steny nosného telesa. Miera tejto difúzie síce závisí na druhu umelohmotného materiálu použitého pre nosné teleso, avšak s nosným telesom z umelej hmoty nie je možné nikdy dosiahnuť absolútnu nepriepustnosť pre plyny, poprípade pary. Aby bola zaistená plynotesnosť, boli v posledných rokoch vyvinuté nosné telesá, ktoré sú tvarovaním za studená vyrobené z vrstvenej hliníkovej fólie. Taká vrstvená fólia pri pohľade na obal zvonka pozostáva smerom dovnútra napríklad z 0,025 mm hrubého orientovaného polyamidu (OPA), 0,045 mm hrubej hliníkovej fólie a 0,060 mm hrubého polyvinylchloridu (PVC), pričom vo vnútri sa nachádzajúca hliníková fólia zaisťuje plynotesnosť, zatiaľ čo s ňou spojené umelohmotné fólie dodávajú nosnému telesu zvýšenú pevnosť, a - ako sa predpokladá - pri tvarovaní za studená zabraňujú výskytu extrémnych pretiahnutí v hliníkovej fólii, ktoré by mohli viesť k jej natrhnutiu. Skúsenosti v každom prípade hovoria, že tvarovatelnosť za studená je u tohto vrstveného materiálu podstatne vyššia, než u rovnocennej normálnej hliníkovej fólie. Také nosné telesá pre pľuzgierové obaly však majú nevýhodu spočívajúcu v tom, že nezodpovedajú súčasným predpisom o odstraňovaní odpadov, podľa ktorých môžu byť prázdne obaly tohto druhu odstraňované ako celok iba vtedy, ak najmenej z 90 % hmotn. pozostávajú z jednotného materiálu. Vo vyššie opísanom príklade je podiel hliníku napríklad len približne 57 % hmotn. Na druhej strane, použitie čisto hliníkových fólií ako nosných telies pre pretlačovacie alebo pľuzgierové obaly sa doposiaľ prakticky nepovažovalo za možné.To extend the shelf life, many drugs are now required to be gas-tight whenever possible. However, this is only possible to a limited extent in conventional extrusion or blister packs, since gases or water vapor can diffuse through the walls of the support body. The extent of this diffusion depends on the type of plastic material used for the support body, but with the plastic support body it is never possible to achieve absolute gas or vapor impermeability. In order to ensure gas-tightness, support bodies have been developed in recent years, which are cold formed from laminated aluminum foil. Such a laminate film, when viewed from the outside, consists of, for example, 0.025 mm thick oriented polyamide (OPA), 0.045 mm thick aluminum foil and 0.060 mm thick polyvinyl chloride (PVC), while the aluminum foil located inside ensures gas tightness while the bonded plastic sheets impart increased strength to the support body and, as is believed, prevent cold extrusion in the aluminum foil which could lead to tearing. In any case, experience suggests that the cold formability of this laminate is significantly higher than that of an equivalent normal aluminum foil. Such blister pack support bodies, however, have the disadvantage that they do not comply with the current waste disposal regulations, according to which empty packagings of this kind can only be removed as a whole if at least 90% by weight of the packaging is removed. consist of a uniform material. In the example described above, the proportion of aluminum is, for example, only about 57% by weight. On the other hand, the use of pure aluminum foils as support bodies for extrusion or blister packaging has so far practically not been considered possible.
Úlohou vynálezu je predovšetkým nájdenie konštrukcie hliníkových fólií s pomerne tenkým povrstvením, ktoré budú mať zlepšenú tvarovatelnosť za studená a ktoré ako materiál s vysokou nepriepustnosťou pre plyny budú vhodné predovšetkým pre nosné telesá pľuzgierových obalov.In particular, it is an object of the present invention to provide a structure of aluminum foils having a relatively thin coating which will have improved cold formability and which, as a material with high gas impermeability, will be particularly suitable for blister pack support bodies.
Podstata vynálezuSUMMARY OF THE INVENTION
Uvedenú úlohu rieši a nedostatky známych povrstvených hliníkových fólií tohto druhu do značnej miery odstraňuje povrstvená hliníková fólia na použitie v procese tvarovania za studená s použitím matricových a patricových nástrojov, podľa vynálezu, ktorého podstata spočíva v tom, že hliníková fólia má hrúbku v rozsahu 0,05 až 0,3 mm a povrstvená plocha na strane matrice má sta3 tický a dynamický súčiniteľ trenia meraný podľa British Standard (BS) 2782 najviac 0,35, výhodne ale najviac 0,30, a/alebo povrstvená plocha hliníkovej fólie na strane patrice má tento súčiniteľ trenia najviac 0,45, výhodne ale najviac 0,40.The problem is solved and the drawbacks of known coated aluminum foils of this kind are largely eliminated by the coated aluminum foil for use in the cold forming process using die and die tools according to the invention, which is characterized in that the aluminum foil has a thickness of 0, 05 to 0.3 mm and the coated side surface has a static and dynamic coefficient of friction measured according to British Standard (BS) 2782 of at most 0.35, preferably at most 0.30, and / or the coated side surface of the aluminum foil has this coefficient of friction is at most 0.45, preferably at most 0.40.

Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Nosné teleso 1 je vyrobené zo za studená tvarovateľného hliníkové pásu hrubého v rozsahu 0,05 až 0,3 mm a kvalite 8079 alebo 8008 podľa Alumínium Association (AA). Tento hliníkový pás je na strane patrice vybavený zvariteľnou umelohmotnou vrstvou 2, napríklad za tepla zvariteľným lakom, hrubou 0,001 až 0,030 mm, výhodne v rozsahu 0,003 až 0,012 mm, pričom na strane matrice je tento hliníkový pás vybavený napríklad neznázornenou vrstvou ochranného laku. Množstvo nanášaného ochranného lakuje napríklad 2g/m2.The support body 1 is made of a cold-deformable aluminum strip in the range 0.05 to 0.3 mm and 8079 or 8008 grade by the Aluminum Association (AA). The aluminum strip is provided with a weldable plastic layer 2, for example a thermally weldable lacquer, of 0.001 to 0.030 mm, preferably in the range of 0.003 to 0.012 mm, on the male side, the aluminum strip being provided with a protective lacquer layer, for example. The amount of protective varnish applied is, for example, 2 g / m 2 .
Pri výrobe nosného telesa i, ktoré je znázornené na výkresoch, sa vyjde napríklad z hliníkového pásu hrubého 0,1 mm, ktorý je na jednej strane vybavený za tepla zvariteľným lakom o hrúbke 0,009 mm. Na tomto povrstvenom hliníkovom páse sa následne v rastre vyrábaného obalu tvarovaním za studená vytvoria nádobky alebo priehlbiny 3 hlboké 4,5 mm. Zväčšenie plochy dosiahnuté tvarovaním za studená v oblasti priehlbín 3. a ich stien 7 je v tomto príklade uskutočnenia približne 35 %. Také zväčšenie plochy by u hliníkového pásu tejto hrúbky bez uvedeného povlaku nebolo reprodukovateľné.In the manufacture of the support body 1 shown in the drawings, for example, a 0.1 mm thick aluminum strip is provided, which on one side is provided with a heat-sealable paint of 0.009 mm thickness. Containers or depressions 3, 4.5 mm deep, are subsequently formed on this coated aluminum strip in a cold-formed raster package. The increase in area obtained by cold forming in the region of the depressions 3 and their walls 7 in this embodiment is approximately 35%. Such an increase in area would not be reproducible with an aluminum strip of this thickness without said coating.
Nádobky alebo priehlbiny 3_ vytvorené takto v nosnom telese i sa potom naplnia baleným tovarom 4, napríklad tabletami. Potom sa nosné teleso 1 prekryje a v netvarovaných oblastiach tohto nosného telesa 1_ v smere šípok 8 za tepla zvarí s hliníkovou uzavieracou fóliou 5. hrubou v rozsahu 0,01 až 0,04 mm, v tomto príklade 0,02 mm, ktorá je na spodnej strane vybavená za tepla zvariteľnou vrstvou 6, výhodne vrstvou za tepla zvariteľného laku hrubého 0,003 až 0,020 mm, v danom príklade hrubého 0,009 mm. Potom sa takto vyrobená vrstvená štruktúra, ktorá už obsahuje balený tovar, vybaví na líniovou perforáciou 9 a obaly sa nakoniec strihom oddelia po obvode 10..The containers or depressions 3 thus formed in the carrier body 1 are then filled with packaged goods 4, for example tablets. Then, the support body 1 is overlapped and welded in the non-shaped regions of the support body 7 in the direction of the arrows 8 with an aluminum sealing foil 5 in the range of 0.01 to 0.04 mm, in this example 0.02 mm, at the bottom a heat-sealable layer 6, preferably a heat-sealable lacquer layer of 0.003 to 0.020 mm thick, in this example 0.009 mm thick. Thereafter, the layered structure thus produced, which already contains the packaged goods, is provided with a line perforation 9 and the packages are finally cut by shearing around the circumference 10.
Na obr. 1, kde je hotový obal znázornený s'jednou nádobkou alebo priehlbinou 3. s vyrezanou hliníkovou uzavieracou fóliou 5., je zrejmá zváracia oblasť 11. ktorá je vyznačená bodkovaním. Obal je možné ľubovolne rozdeľovať podľa líniových perforácií 9. Podiel hliníku v prázdnom obale, to je v základnom telese 1 a uzavieracej fólii 5, je v tomto príklade uskutočnenia 94 % hmotn.In FIG. 1, where the finished package is shown with one container or recess 3 with an aluminum closure foil 5 cut out, the welding region 11, which is marked by a dotted line, is evident. The package can be arbitrarily divided according to line perforations 9. The proportion of aluminum in the empty package, i.e. in the base body 1 and the sealing film 5, in this embodiment is 94% by weight.
Priemyselná využiteľnosťIndustrial usability
Povrstvená hliníková fólia podľa vynálezu je výhodná ako baliaci materiál pre pretlačovacie alebo pľuzgierové obaly, ktoré sa používajú vo farmácii a ktoré sa po vyprázdnení môžu jednoducho vyhodiť.The coated aluminum foil according to the invention is advantageous as packaging material for extrusion or blister packs which are used in pharmacy and which can be easily discarded after emptying.
