Spôsob výroby obaluMethod of manufacturing a package
Oblasť technikyTechnical field
Vynález sa týka spôsobu výroby obalu zhotoveného z pružného materiálu, napríklad umelohmotnej fólie, papiera, hliníkovej fólie a pod., ktorý sa môže otvárať roztrhnutím.The invention relates to a method of manufacturing a package made of a resilient material, for example a plastic film, paper, aluminum foil and the like, which can be torn open.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Na otváranie takých obalov sú zvyčajne potrebné nákladné pomocné prostriedky, umožňujúce roztrhnutie obalu, ktorých nanášanie je ale pri výrobe obalu veľmi ťažké.Expensive aids to tear the package are usually required to open such packages, but are difficult to apply in the manufacture of the package.
Podstata vynálezuSUMMARY OF THE INVENTION
Cieľom vynálezu je vytvoriť taký spôsob vyroby obalu úvodom uvedeného typu, aby ako výroba, tak otváranie tohto obalu boli podstatne uľahčené.It is an object of the present invention to provide such a method of manufacturing a container of the type mentioned above, so that both the manufacture and opening of the container are substantially facilitated.
Tento cieľ je podľa vynálezu riešený tým, že pružný materiál je urobený tak, aby sa dal trhať vo všetkých smeroch, pričom materiál je opatrený presne ohraničeným otváracím prostriedkom v tvare prúžka, a podľa jeho vonkajšej hrany je vedená linka, označujúca miesto, kde dochádza k odtrhnutiu materiálu.This object is achieved according to the invention in that the resilient material is made to tear in all directions, the material being provided with a precisely defined opening means in the form of a strip, and along its outer edge a line indicating the place where it occurs tearing off the material.
Ľahké odtrhnutie obalu je umožnené dodatočným nánosom otváracieho prostriedku v tvare prúžka, vedeného v požadovanom smere otvárania.Slight tearing of the package is made possible by additional deposition of a strip-shaped opening means guided in the desired opening direction.
Tento spôsob výroby obalu je pritom vhodný pre rôzné materiály, ako napríklad umelohmotné fólie, fóliolamináty, papier, pergamen, celofán, hliníkovú fóliu, lamináty alebo podobné materiály.This method of making the packaging is suitable for various materials, such as plastic films, foil laminates, paper, parchment, cellophane, aluminum foil, laminates or the like.
Ďalší výhodný spôsob výroby podľa vynálezu sa vyznačuje tým, že umelohmotná fólia je predlžiteľná v dvoch osách a je opatrená presne ohraničeným nánosom, najmä nánosom laku.Another advantageous production method according to the invention is characterized in that the plastic film is extensible in two axes and is provided with a precisely defined coating, in particular with a coating of varnish.
Umelohmotné fólie, predĺžiteľné v dvoch osách, je možno ľahko trhať vo všetkých smeroch, pričom presne ohraničený otvárací prostriedok v tvare prúžka nasmeruje roztrhnutie do požadovaného smeru.The plastic films, extensible in two axes, can be easily torn in all directions, with a precisely defined strip-shaped opening means directing the tearing in the desired direction.
Ako mimoriadne výhodný sa javí ďalší spôsob výroby obalu podľa vynálezu, podľa ktorého je pružný materiál na okraji obalu opatrený pomocným prostriedkom v tvare zárezu alebo trhliny na ľahšie natrhnutie, pričom roztrhnutie pružného materiálu obalu, začaté pomocným prostriedkom, prebieha ďalej pozdĺž vonkajšej hrany otváracieho prostriedku v tvare prúžka.It is particularly advantageous to provide a further method of manufacturing a package according to the invention, wherein the resilient material at the edge of the package is provided with a notch or tear aid to facilitate tearing, wherein the tearing of the resilient package material initiated by the aid extends along the outer edge of the opening means. stripe shape.
Linka, naznačujúca roztrhnutie pružného materiálu obalu, takA line indicating the rupture of the resilient wrapper material, so
v tom, že presne ohraničený otvárací prostriedok v tvare prúžka je nanesený na tú stranu pružného materiálu obalu, ktorá neskôr tvorí vonkajšiu stranu obalu. Tým je zaistené presné vedenie trhaného materiálu.in that the precisely defined opening means in the form of a strip is applied to the side of the resilient material of the package which later forms the outside of the package. This ensures accurate guidance of the shredded material.
Podľa ďalšieho spôsobu výroby obalu podľa vynálezu môže byť presne ohraničený otvárací prostriedok v tvare prúžka nanesený na tú stranu umelohmotnej fólie, ktorá neskoršie tvorí vnútornú stranu obalu.According to a further method of manufacturing the package according to the invention, a precisely delimited strip-shaped opening means can be applied to the side of the plastic film which later forms the inner side of the package.
Toto vyhotovenie je výhodné najmä vtedy, ak by tento presne ohraničený otvárací prostriedok v tvare prúžka negatívne ovplyvnil vzhľad obrázka, ktorý má byť vytlačený na vonkajšej strane obalu.This embodiment is particularly advantageous if this precisely defined strip-shaped opening means would adversely affect the appearance of the image to be printed on the outside of the package.
Ďalšie výhodné vyhotovenie vynálezu spočíva v tom, že keď je obal zhotovený z laminátu, je presne ohraničený otvárací prostriedok v tvare prúžka urobený medzi jeho jednotlivými vrstvami.Another advantageous embodiment of the invention is that when the package is made of laminate, a strip-shaped opening means formed between its individual layers is precisely delimited.
Ako veľmi výhodný sa ďalej osvedčil taký spôsob výroby obalu podľa vynálezu, u ktorého je presne ohraničený otvárací prostriedok v tvare prúžka urobený tak, že roztrhnutie materiálu, vychádzajúce od vonkajšiej hrany obalu, tvoreného pružným materiálom, zviera ostrý uhol s vonkajšou stranou otváracieho prostriedku v tvare prúžka.Furthermore, a method according to the invention has been found to be very advantageous, in which the precisely defined strip-shaped opening means is designed such that the tearing of the material extending from the outer edge of the resilient material is at an acute angle with the outer side of the opening means strip.
Takto je dosiahnutá zmena smeru začatého trhania a jeho ďalšieho bezpečného vedenia.In this way a change in the direction of started tearing and its further safe guidance is achieved.
Podľa jedného z výhodných spôsobov výroby obalu podľa vynálezu smeruje hrana otváracieho prostriedku v tvare prúžka priamočiare.According to a preferred method of manufacturing the packaging according to the invention, the edge of the opening means in the form of a strip is directed rectilinear.
Je ale takisto možné, aby podľa ďalšieho vyhotovenia vynálezu bola hrana otváracieho prostriedku v tvare prúžka zakrivená.However, it is also possible, according to a further embodiment of the invention, that the edge of the opening means in the form of a strip is curved.
Tvar hrany otváracieho prostriedku v tvare prúžka pritom môže byť určený v závislosti na tom, akým spôsobom má byť obal otvorený.The strip shape of the opening means in the form of a strip can be determined depending on how the package is to be opened.
Výhodný je najmä spôsob výroby obalu podľa vynálezu, ktorý sa vyznačuje tým, že presne ohraničený otvárací prostriedok v tvare prúžka je na pružný materiál nanášaný počas procesu tlače.In particular, the method according to the invention is advantageous in that the precisely defined strip-shaped opening means is applied to the elastic material during the printing process.
Podľa ďalšieho výhodného spôsobu výroby obalu podľa vynálezu môže byť presne ohraničený otvárací prostriedok v tvare prúžka nanášaný na pružný materiál pomocou tlaku, napríklad spôsobom tlakovej tlače.According to a further preferred method of manufacturing the packaging according to the invention, a precisely delimited strip-shaped opening means can be applied to the elastic material by pressure, for example by means of a pressure printing method.

Príklady vyhotovenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Na obr. 1 je znázornený obal i., na ktorého zadnej strane je vytvorený pozdĺžny spoj 2 a hore a dole takisto priečny spoj 3 a 4· Tieto spoje môžu byť urobené ľubovoľným spôsobom. V oblasti priečneho spoja 2 je v oboch vrstvách obalu £ vyrezaný zárez £, ktorý slúži na lahSie natrhnutie materiálu. Pri natrhnutí obalu £ v záreze ä dochádza k roztrhnutiu prednej a zadnej strany a trhanie prebieha približne pozdĺž čiarkované znázornenej linky £. Roztrhnutie prebieha až k otváraciemu prostriedku v tvare prúžka 7, ktorý je urobený na prednej strane obalu. Pozdĺž hrany S. otváracieho prost-redku v tvare prúžka 7 pokračuje trhanie ďalej proti vonkajšej hrane obalu £, a tak sa odstráni časť obalu, ležiaca medzi zárezom S, hranou a vonkajšou hranou obalu, a dochádza tak k úplnému otvoreniu obalu, ktoré j© nevyhnutné na to, aby sa vybral tovar.In FIG. 1 shows a package 1, on the back of which a longitudinal joint 2 is formed and a transverse joint 3 and 4 are also provided at the top and bottom. These joints can be made in any way. In the area of the transverse joint 2, a notch 4 is cut in both layers of the package 4, which serves to tear the material slightly. Upon tearing of the package 8 in the notch ä, the front and back sides tear and tearing takes place approximately along the dashed line shown. The rupture extends to the opening means in the form of a strip 7 which is provided on the front of the package. Along the edge S of the opening means in the form of the strip 7, tearing continues further against the outer edge of the package 8, thus removing the portion of the package lying between the notch S, the edge and the outer edge of the package, thereby completely opening the package. necessary to collect the goods.
Ako je znázornené na obr. 2, namiesto priamočiare prebiehajúceho otváracieho prostriedku v tvare prúžka Z môže byť predná strana obalu opatrená takisto zakrivené prebiehajúcim otváracím prostriedkom v tvare prúžka 27. Aj tu zasahuje linka naznačujúca roztrhnutie 6, ktorá vychádza zo zárezu 5, až k hrane 2S otváracieho prostriedku v tvare prúžka 27 a je potom vedená k vonkajäej hrane obalu 21.As shown in FIG. 2, instead of a rectilinear strip-shaped opening means Z, the front side of the package may also be provided with a curved strip-opening means 27 which also protrudes. 27 and is then guided to the outer edge of the package 21.
V prípade, keby presne ohraničený otvárací prostiedok v tvare prúžka Z, príp. 2Z, narušoval tlač prednej strany obalu, mohol by byť otvárací prostriedok urobený aj na vnútornej strane obalu.In the case of a precisely delimited opening device in the form of a strip Z, resp. 2Z, disrupting the printing of the front of the package, the opening means could also be provided on the inside of the package.
Presne ohraničený otvárací prostriedok v tvare prúžka môže byť urobený aj na zadnej strane obalu.A precisely defined opening means in the form of a strip can also be provided on the back of the package.
Pri použití laminátu ako obalového materiálu môže byť presne ohraničený otvárací prostriedok v tvare prúžka uložený medzi jednotlivými vrstvami laminátu.When using the laminate as packaging material, a precisely delimited strip-shaped opening means may be interposed between the individual layers of the laminate.
Na obr. 3 je zobrazené príkladné vyhotovenie vynálezu pomocou plošného obalového prírezu 31 z pružného materiálu, ktorý je neskôr zložený do tvaru obalu pozdĺž čiarkovanej linky 32. Predná strana 212 je opatrená tlačou, zatiaľ čo na zadnej strane 34 je urobený presne ohraničený otvárací prostriedok v tvare prúžka 3Z s hranou ,28. Na prednej strane 33 môže byť vytlačená dodatečne ešte linka naznačujúca smer trhania materiálu.In FIG. 3, an exemplary embodiment of the invention is shown using a sheet blank 31 of resilient material which is later folded into a wrapper along a dashed line 32. The front side 212 is provided with printing while a rearwardly defined strip opening means 3Z is provided on the rear side 34. with edge, 28. On the front side 33 a line indicating the tearing direction of the material can be additionally printed.
Ako materiál otváracieho prostriedku v tvare prúžka prichádzajú do úvahy najmä laky, ktoré vytvárajú presne ohraničené hrany, ktoré umožňujú nasmerovať začaté trhanie. Ako otvárací prostriedok v tvare prúžka však prichádzajú do úvahy aj farby, lepidlá, lepidlo tvrdnúce za studená, a to buď samostatne alebo v kombinácii s inou látkou.Suitable materials for the strip-shaped opening means are, in particular, lacquers which form precisely defined edges which make it possible to direct the starting tearing. However, paints, adhesives, cold-curing adhesives, either alone or in combination with another substance, are also suitable as strip-opening means.
Je účelné, keď je nanášanie otváracieho prostriedku v tvare prúžka urobené počas tlače, a to najmä pomocou toho istého stroja, ktorý nanáša aj zvyšnú tlač.It is expedient if the application of the strip-shaped opening means is carried out during printing, in particular by means of the same machine which also applies the remaining printing.
Na nanášanie otváracieho prostriedku v tvare prúžka prichádza do úvahy aj použitie tlaku, napríklad tlakovej tlače, a tak sa môžu docieliť uspokojivé hodnoty.The application of a strip-shaped opening means also involves the use of pressure, for example pressure printing, so that satisfactory values can be achieved.
