Description

Foreliggende oppfinnelse angår en stablbar, traulignende innpakning med ubrutt kantflens og avrundede hjerner. The present invention relates to a stackable, trough-like packaging with an unbroken edge flange and rounded cores.

I første rekke angår oppfinnelsen slike forpakninger som er væske- og/eller lufttette og ved hvis flensparti kan anbringes et lokk for lukking av forpakningen. Ved slike forpakninger er det av betydning at flenspartiet får en øvre overflate som er så plan som mulig for at ikke lekkasje skal oppstå mellom trau og lokk. Det er også ønskelig å kunne fremstille for-pakningene ved bretting av et på forhånd utstanset emne. Problemet ved fremstillingen ved forpakninger av nevnte type er forpakningens hjørner som må utformes slik at nevnte beting-elser oppfylles samtidig som produktet skal kunne fremstilles ved en for masseproduksjon egnet fremstillingsprosess ved hjelp av billig apparatur. Hvis man utformer hjørnene i bunnen og/eller oppe med rette vinkler ved bretting av hjørne-feltene langs et antall brettelinjer og utsparinger i kant-flensene, blir forpakningen ikke lenger stablbar. Videre må man ta i betraktning at jo fler fliker som må brettes over hverandre i hjørnene, desto mer komplisert blir den brette-mekanisme som kreves for å brette flikene over hverandre. Har man rettvinklede hjørner, får man videre fare for såkalt spiss-virkning ved varming av forpakningen i mikrobølgeovn, dvs. varme fra to forskjellige retninger møtes i hjørnene og be-virker at innholder brennes. Hvis man har altfor mange brettelinjer som løper sammen i samme hjørne, blir det umulig å konstruere et verktøy for maskinmessig fremstilling av produktet da brettene vil komme til å ligge for nær hverandre. Hver brettelinje opptar en viss bredde og jo fler slike møtes Primarily, the invention relates to such packages which are liquid and/or airtight and at whose flange part a lid can be placed for closing the package. With such packages, it is important that the flange section has an upper surface that is as flat as possible so that leakage does not occur between the trough and the lid. It is also desirable to be able to produce the packages by folding a pre-punched blank. The problem with the production of packages of the aforementioned type is the corners of the package, which must be designed so that the aforementioned conditions are met at the same time that the product must be able to be produced by a manufacturing process suitable for mass production using cheap equipment. If the corners at the bottom and/or top are designed at right angles by folding the corner panels along a number of fold lines and recesses in the edge flanges, the packaging will no longer be stackable. Furthermore, it must be taken into account that the more tabs that have to be folded over each other in the corners, the more complicated the folding mechanism required to fold the tabs over each other becomes. If you have right-angled corners, you also run the risk of a so-called tip effect when heating the packaging in a microwave oven, i.e. heat from two different directions meets in the corners and causes the contents to burn. If you have far too many fold lines that run together in the same corner, it becomes impossible to construct a tool for machine-based production of the product as the folds will be too close to each other. Each folding line occupies a certain width and the more such lines meet

i et hjørne, desto vanskeligere blir det teknisk å gjennom-føre dette. Det er på den annen side et ønske å få brettelinjene til å slutte så nær bunnen som mulig, da i motsatt in a corner, the more difficult it will be technically to implement this. On the other hand, there is a desire to make the fold lines end as close to the bottom as possible, then in the opposite direction

fall forpakningen sporer ut ved brettingen og brettingen blir feilaktig. Har man en ubrutt kantflens, hvilket i og for seg er en fordel, og denne kantflens overalt er like bred, oppstår problemet at man etter brettingen får trappetrinnsform-ede utbuktninger utenfor den vanlige kant, hvilket er en ulempe. Kompenserer man videre ved konstruksjonen av en for-pakning ikke for materialets tykkelse, får man etter brettingen store spenninger i materialet når flikene brettes over hverandre, hvilket fører til at plast og basismateriale sprek-ker - særlig når basismaterialet utgjøres av kartong, hvilket gir lekkasje som ikke kan tåles. Endelig må man ved konstruksjonen av forpakninger av ovennevnte type passe på at det ikke oppstår råkanter i hjørnene .som kan komme i kontakt med inn-holdet og suge opp dette, hvis det er flytende, hvorved forpakningen misfarges og råkanten eventuelt oppløses og går i stykker. if the packaging tracks out during folding and the folding is incorrect. If you have an unbroken edge flange, which in itself is an advantage, and this edge flange is everywhere the same width, the problem arises that after folding you get step-shaped protrusions outside the normal edge, which is a disadvantage. Furthermore, if you do not compensate for the thickness of the material during the construction of a package, after folding you get large stresses in the material when the flaps are folded over each other, which causes the plastic and base material to crack - especially when the base material is cardboard, which causes leakage which cannot be tolerated. Finally, in the construction of packages of the above type, care must be taken to ensure that no raw edges are created in the corners, which can come into contact with the contents and absorb this, if it is liquid, whereby the packaging becomes discolored and the raw edge eventually dissolves and breaks. .

Foreliggende oppfinnelse tar sikte på å skaffe en stablbar, traulignende innpakning med sammenhengende kantflens og avrundede hjørner fremstilt ved oppreisning til mindre enn 90° vinkel med horisontalplanet av et plant emne og belgformet bretting og sammenføyning av hjørnene, idet emnet for innpakningen i hvert hjørne er forsynt med av brettelinjer avgrensede, hovedsakelig triangulære hjørnefelter anordnet på hver side av et i det vesentlige rektangulært, sentralt hjørne-felt, idet brettelinjene på hver side åv det sentrale hjørne-felt hver konvergerer mot samme punkt og oppfinnelsen utmerker seg ved at den hjørnefeltets ytterdel dannende, ubrutte kantflens er slik utformet at kantflensens ytterdel for det sentrale hjørnefelt og de inntil dette liggende triangulære hjørnefelter begrenses av en buelinje, slik at kantflensen får' varierende bredde og er smalest der hvor de rette linjer mater buelinjen, og at kantflensens brettelinje i det sentrale hjørnefelt er bueformet og befinner seg lengre bort fra konvergeringspunktet enn de triangulære hjørnefelters The present invention aims to provide a stackable, trough-like package with continuous edge flange and rounded corners produced by erecting to less than 90° angle with the horizontal plane of a flat blank and bellows-shaped folding and joining of the corners, the blank for the package in each corner being provided with mainly triangular corner fields delimited by fold lines arranged on each side of an essentially rectangular, central corner field, the fold lines on each side of the central corner field each converging towards the same point and the invention is distinguished by the fact that the outer part of the corner field forming , unbroken edge flange is designed in such a way that the outer part of the edge flange for the central corner field and the adjacent triangular corner fields are limited by an arc line, so that the edge flange has a varying width and is narrowest where the straight lines feed the arc line, and that the fold line of the edge flange in the central corner field is arched and located further away from the point of convergence than that of the triangular corner fields

brettelinjer . folding lines.

På tegningene er som eksempel vist en utførelses-form av oppfinnelsen, idet fig. 1 viser en del av det til fremstilling av en rektangulær innpakning beregnede emne i plan tilstand, fig. 2 v/iser brettingen av en del av veggpar-tier som danner et av innpakningens hjørner, fig. 3 viser det således oppnådde hjørne i perspektiv og fig. 4 viser et snitt gjennom et hjørne etter linjen IV-IV på fig. 2. The drawings show, as an example, an embodiment of the invention, as fig. 1 shows part of the workpiece intended for the production of a rectangular package in a flat state, fig. 2 shows the folding of a part of the wall parts which form one of the corners of the packaging, fig. 3 shows the thus obtained corner in perspective and fig. 4 shows a section through a corner along the line IV-IV in fig. 2.

Til fremstilling av den på tegningen viste innpakning, som er beregnet på anvendelse i forbindelse med distri-busjon av matvarer eller lignende, som må være innesluttet i. en væsketett innpakning, går man ifølge oppfinnelsen ut fra et stanset og eventuelt preget emne 1 som består av et kartong-materiale, som på begge sider er belagt med et varmeforsegl-bart lag, fortrinnsvis polypropen eller polyeten. Oet plast-lag som er anordnet på den del av emnet som skal utgjøre innpakningens indre, er hensiktsmessig betydelig tykkere enn det på yttersiden anbragte belegg, f.eks. dobbelt så tykt. For the production of the packaging shown in the drawing, which is intended for use in connection with the distribution of foodstuffs or the like, which must be contained in a liquid-tight packaging, the invention is based on a punched and possibly embossed blank 1 which consists of of a cardboard material, which is coated on both sides with a heat-sealable layer, preferably polypropylene or polyethylene. A plastic layer which is arranged on the part of the blank which is to make up the interior of the packaging, is suitably considerably thicker than the coating placed on the outside, e.g. twice as thick.

Det på fig. 1 delvis viste emne omfatter en bunnflate 2 som via brettelinjer 3 og 4 går over i innpakningens tilsvarende sideveggpartier 5 og 6. Disse sidepartier går på That in fig. 1 partially shown blank comprises a bottom surface 2 which, via fold lines 3 and 4, transitions into the packaging's corresponding side wall sections 5 and 6. These side sections go on

sin side via brettelinjer 7, 7' over i flenspartier 8, 8'. Bunnflaten 2 står videre gjennom en bueformet brettelinje 9 its side via folding lines 7, 7' over into flange sections 8, 8'. The bottom surface 2 continues through an arc-shaped folding line 9

i forbindelse med et hjørnesegment (et midtfelt) 10 som gjennom brettelinjer 11, 11' står i forbindelse med første overgangssegment 12, 12', hvilke hvert på sin side via fra punkter 13, 13' hvorfra også brettelinjene 11, 11' går ut, utgående brettelinjer 14, 14' går over i andre overgangssegmenter 15, 15', som gjennom likeledes fra punktene 13, 13' utgående in connection with a corner segment (a central field) 10 which through fold lines 11, 11' is connected to the first transitional segment 12, 12', each of which in turn via from points 13, 13' from which the fold lines 11, 11' also exit, outgoing folding lines 14, 14' pass into other transition segments 15, 15', which likewise from points 13, 13' outgoing

brettelinjer 16, 16' går over i tredje overgangssegment 17, folding lines 16, 16' pass into the third transition segment 17,

17' som via fra punktene 13, 13' utgående brettelinjer 18, 18' står i forbindelse med den nærliggende side 5 henholdsvis 6. Linjene 11, 11', 14, 14', 16, 16' og 18, 18' behøver ikke gå 17' which via fold lines 18, 18' emanating from points 13, 13' are connected to the nearby side 5 and 6 respectively. The lines 11, 11', 14, 14', 16, 16' and 18, 18' do not need to go

ut fra punktene 13, 13', men derimot deres forlengelser. Som det fremgår av fig. 1, er de to halvdeler av hjørnekonstruk-sjonene speilvendte i forhold til hverandre. based on points 13, 13', but on the other hand their extensions. As can be seen from fig. 1, the two halves of the corner constructions are mirrored in relation to each other.

Hjørnesegmentet 10 står gjennom en bueformet brettelinje 19 i forbindelse med et flensparti 20 som har bueformet ytre kontur. På tilsvarende måte står segmentene 12, 12' gjennom brettelinjer 21, 21' i forbindelse med flenssegmenter 22, 22<*> og segmentene 15, 15' står via brettelinjer 23, 23' The corner segment 10 stands through an arcuate folding line 19 in connection with a flange portion 20 which has an arcuate outer contour. In a similar way, the segments 12, 12' stand through fold lines 21, 21' in connection with flange segments 22, 22<*> and the segments 15, 15' stand via fold lines 23, 23'

i forbindelse med flenssegmenter 24, 24'. Segmentene 17, 17' in connection with flange segments 24, 24'. Segments 17, 17'

står,endelig på samme måte gjennom brettelinjer 25, 25'. i forbindelse med flenspartier 26, 26'. Som det fremgår av fig. 1, befinner brettelinjene 19, 21, 21', 23, 23' og 25,. 25' seg i forskjellig avstand fra de felles punkter 13, 13' stands, finally in the same way through folding lines 25, 25'. in connection with flange parts 26, 26'. As can be seen from fig. 1, the fold lines 19, 21, 21', 23, 23' and 25 are located. 25' at different distances from the common points 13, 13'

og årsaken til dette er at flenssegmentene ved innpakningens oppbretting skal komme til å ligge i det vesentlige i ett og samme plan. For samme formål er i flenssegmentene 22, 22' anordnet mindre utsparinger 27, 27', hvis oppgave er å tynne ut materialet på de steder hvor tre materiallag ligger over-for hverandre. Brettelinjene 11, 11' har endelig sine ytre deler 28, 28' forløpende i svak vinkel i forhold til resten av brettelinjen for et formål som skal forklares senere. and the reason for this is that the flange segments when the packaging is folded up will essentially lie in one and the same plane. For the same purpose, smaller recesses 27, 27' are arranged in the flange segments 22, 22', the task of which is to thin out the material in the places where three layers of material lie one above the other. The fold lines 11, 11' finally have their outer parts 28, 28' extending at a slight angle in relation to the rest of the fold line for a purpose to be explained later.

Ifølge oppfinnelsen foregår innpakningens fremstilling slik at emnet fra den på fig. 1 viste plane tilstand i et spesielt verktøy brettes opp, idet overgangssegmentene belgformet brettes over hverandre og i tilknytning dertil forsegles til hverandre. Som der fremgår av fig. 2 og 4, brettes derved segmentet 15 utover slik at det med sin ytterside kommer til å ligge an mot segmentets 17 ytterside. Derved kommer også segmentets 17 flensparti 26 til anlegg mot segmentets 15 flensparti 24. I forbindelse med denne bretting føres segmentets 15 innerside til anlegg mot segmentets 12 innerside og samtidig vil dette segments flensdeler 24 og 22 komme i kontakt med hverandre. l/ed denne bretting foregår hensiktsmessig også flenspartienes ombøyning. I forbindelse med brettingen eller umiddelbart før, påføres varme f.eks.; ved hjelp av termostatoppvarmede linjaler til segmentene 12, 15 og 17 og deres flensdeler. Derved bringes materialets tilsvarende varmeforseglingsbare lag til smelting, slik at en stadig forbindelse oppnås mellom segmentene. Herved kommer segmentets 17 ytre flate til å bli sveiset fast til segmentets 15 ytre flate og sistnevnte segments indre flate kommer til å sveises fast mot segmentets 12 indre flate. En tilsvarende forsegling finner selvfølgelig også sted mellom tilsvarende deler av flenssegmentene. Som nevnt vil utsparingen eller hakket 27 bevirke en uttynning av materialet i den del av flenspartiet hvor tre materiallag befinner seg ovenpå hverandre. Ved den lille vinkel-avvikelse for brettedelen 28 kan hjørneelementets 10 flensdel 20 ved hjelp av en i verktøyet anordnet knast eller lignende løftes opp så meget at nevnte flensparti 20 kommer i nivå med hjørnets øvrige flenspartier. Brettelinjene 9 og 19 er som nevnt bueformede, hvilke for-uten det avrundede hjørne også medfører at angjeldende flensparti får tendens til å bøye seg utover uten foldedannelse. According to the invention, the packaging is produced so that the subject from the one in fig. 1 shown in a flat state is folded up in a special tool, the transitional segments being folded over each other in a bellows shape and in connection therewith sealed to each other. As can be seen from fig. 2 and 4, the segment 15 is thereby folded outwards so that its outer side rests against the outer side of the segment 17. Thereby also the flange part 26 of the segment 17 comes into contact with the flange part 24 of the segment 15. In connection with this folding, the inner side of the segment 15 is brought into contact with the inner side of the segment 12 and at the same time the flange parts 24 and 22 of this segment will come into contact with each other. With this folding, the bending of the flange sections also takes place appropriately. In connection with the folding or immediately before, heat is applied, for example; using thermostatically heated rulers to segments 12, 15 and 17 and their flanged parts. Thereby, the corresponding heat-sealable layer of the material is brought to melting, so that a permanent connection is achieved between the segments. Hereby, the outer surface of the segment 17 will be welded firmly to the outer surface of the segment 15 and the inner surface of the latter segment will be welded firmly to the inner surface of the segment 12. Of course, a corresponding seal also takes place between corresponding parts of the flange segments. As mentioned, the recess or notch 27 will cause a thinning of the material in the part of the flange portion where three layers of material are located on top of each other. In the case of the small angular deviation for the folding part 28, the flange part 20 of the corner element 10 can be lifted up so much that said flange part 20 is level with the other flange parts of the corner with the help of a cam arranged in the tool or the like. The folding lines 9 and 19 are, as mentioned, arc-shaped, which, apart from the rounded corner, also means that the relevant flange part tends to bend outwards without folding.

De tilsvarende deler i hjørnets annen halvdel brettes og behandles på tilsvarende måte, slik at hele det fer-dige hjørne får det utseende som i prinsipp er vist-på fig. 3. The corresponding parts in the second half of the corner are folded and processed in a similar way, so that the entire finished corner takes on the appearance that is shown in principle in fig. 3.
