Description

Emballasje, særlig for næringsmidler. Packaging, especially for foodstuffs.

Foreliggende oppfinnelse angår en emballasje som i forste rekke er beregnet til næringsmidler og særlig slike næringsmidler som skal oppvarmes i emballasjen ved at denne anbringes i en hoyfrekvensovn, et varmebad eller på en varmeplate. Emballasjen ifolge oppfinnelsen kan imidlertid også med fordel, brukes for næringsmidler som ikke skal oppvarmes, men som allikevel bor være pakket i en tett pakning. The present invention relates to packaging which is primarily intended for foodstuffs and in particular such foodstuffs which are to be heated in the packaging by placing it in a high-frequency oven, a heating bath or on a hot plate. However, the packaging according to the invention can also be used with advantage for foodstuffs which are not to be heated, but which should nevertheless be packed in a tight package.

For å pakke ferdiglaget mat i såkalte porsjonspakning-er, har man hittil brukt trau eller begre av plast eller aluminium-folie. He dyptrukne plastfolier utfores imidlertid av en plast som ikke tåler oppvarming i hoyfrekvensovn eller på varmeplate med ca. 120°C. Begere av aluminiumsfolie er elektrisk ledende og kan av denne grunn ikke brukes for oppvarming i hoyfrékvensovn. To pack ready-made food in so-called portion packs, trays or cups made of plastic or aluminum foil have been used until now. However, deep-drawn plastic foils are made of a plastic that cannot withstand heating in a high-frequency oven or on a hot plate with approx. 120°C. Cups made of aluminum foil are electrically conductive and for this reason cannot be used for heating in a Hoyfréquen oven.

En annen ulempe med disse begre er at det byr på visse vanske-ligheter å forsyne dem med trykte tekster og bilder, f.eks. for instruksjoner og reklame. Alle disse ulemper kan unngås dersom trauet eller begeret utfores av kartongmateriale som dels tåler temperaturer opp til vanlig forekommende oppvarmingstemperaturer omkring 150°C, og som dessuten med letthet kan forsynes med trykte tekster og bilder. Another disadvantage of these cups is that it presents certain difficulties to supply them with printed texts and images, e.g. for instructions and advertising. All these disadvantages can be avoided if the trough or beaker is lined with cardboard material which partly withstands temperatures up to commonly occurring heating temperatures of around 150°C, and which can also be easily supplied with printed texts and images.

Hensikten med oppfinnelsen er derfor å fremskaffe en kartongemballasje med tilfredsstillende tetthet, holdfasthet og stabilitet for å kunne oppvarmes i ovn eller på varmeplate, og som lett kan åpnes samt dessuten er så stabil at man kan bruke den direkte som matkar til å spise fra, dersom dette onskes. Dessuten skal emballasjen kunne reises og lukkes maskinelt. The purpose of the invention is therefore to provide a cardboard packaging with satisfactory density, holding strength and stability to be able to be heated in an oven or on a hot plate, and which can be opened easily and is also so stable that it can be used directly as a food container to eat from, if this is desired. In addition, the packaging must be able to be lifted and closed mechanically.

Dette oppnås ifolge oppfinnelsen ved hjelp av et emballasjetrau bestående av et eneste kartongemne og lukkbart ved hjelp av separat lokk, idet trauet oppviser en rektangulær bunn og fire sidevegger som er forbundet med hverandre parvis ved en hjornekonstruksjon som danner en;..hjornestolpe, bestående av tre triangulære felt som sammenloper i en felles spiss i bunnflatens nærliggende hjornekant og som består av et midtfelt og to sidefelt som ligger an mot nærliggende sidevegger av trauet og sammen med midtfeltet danner en i tverrsnitt trekantet, hul stolpe, idet det karakteristiske ved "'oppfinnelsen 'består i at sideveggene ved sine ovre kanter er forlenget med kantfliker som er utboyd og ligger i et plan parallelt med trauets bunn og som er parvis i sine hjorner forbundet med hverai dre over en forbindelsesflik som danner en forlengelse av hjornestolpens midtfelt samt er boyd over de utover-bretted kantflikene og forseglet til disse for sammen med disse å danne en sammenhengende plan flens-eller ramme for mottagning av lokket. This is achieved according to the invention by means of a packaging trough consisting of a single cardboard blank and closable by means of a separate lid, the trough having a rectangular bottom and four side walls which are connected to each other in pairs by a corner construction which forms a;..corner post, consisting of three triangular fields which converge at a common point in the near corner edge of the bottom surface and which consist of a central field and two side fields which lie against nearby side walls of the trough and together with the central field form a cross-section triangular, hollow post, the characteristic of the "'invention 'consists of the side walls being extended at their upper edges with edge flaps which are flared out and lie in a plane parallel to the bottom of the trough and which are connected in pairs at their corners with each rail over a connecting flap which forms an extension of the center field of the corner post and is bowed over the outward-folded edge flaps and sealed to these to together with these form a continuous plane flange or frame for receiving the lid.

To hensiktsmessige utforelsesformer for emballasjen ifolge oppfinnelsen skal i det folgende forklares nærmere ved hjelp av tegningen. Two suitable embodiments of the packaging according to the invention will be explained in more detail in the following with the help of the drawing.

Lokket i fig. 1 og 7 og emnet til trauet i fig. 3 °g The lid in fig. 1 and 7 and the blank for the trough in fig. 3 °g

4 består av kartongmateriale som i det minste på den mot trauet indre vendte side,,har et væsketett, forseglbart belegg, som f.eks. kan være av polypropen. På lokkets og trauets utsider kan det være trykte tekster og bilder; I visse tilfeller kan det være hensiktsmessig å bruke et trau med plastbelegg på såvel innsiden som utsiden. 4 consists of cardboard material which, at least on the inner side facing the trough, has a liquid-tight, sealable coating, such as e.g. can be made of polypropylene. There may be printed texts and images on the outside of the lid and the trough; In certain cases, it may be appropriate to use a trough with a plastic coating on both the inside and the outside.

Emnet i fig. 3 er ved hjelp av brettelinjer, inndelt i The subject in fig. 3 is by means of fold lines, divided into

en bunn 10 og fire sider 11, 12, 13, 14- Sidenes ender går over i hjornestykker 15, som ved hjelp av to brettelinjer, 16, 17, er inndelt i en midtseksjon l8 og to sideseksjoner 19, 20. Ved hvert hjorne er vinkelen mellom brettelinjene 21, 22, som definerer side-kantenes endekanter, mindre enn 90 grader for at sidene skal skråne ned mot bunnen 10 i reist stilling. Ved denne konisitet fåes storre stabilitet på trauet, og dessuten lettes tomningen. a bottom 10 and four sides 11, 12, 13, 14 - The ends of the sides merge into corner pieces 15, which are divided by means of two folding lines, 16, 17, into a central section l8 and two side sections 19, 20. At each corner, the angle between the fold lines 21, 22, which define the end edges of the side edges, less than 90 degrees in order for the sides to slope down towards the bottom 10 in the raised position. With this conicity, greater stability is obtained on the trough, and it also facilitates emptying.

Midtsektoren l8 er ved sin ovre kant forlenget med en festeflik 23 som er brettbar langs en brettelinje 24 som definerer midtsektorens ovre kant. Ved endene av denne brettelinje er det opptatt slisser 2.5, 26 som strekker seg et stykke inn langs brettelinjen 24, for å muliggjore en spesiell egenskap hos trauet på den måte som skal beskrives nedenfor. The middle sector 18 is extended at its upper edge with a fastening tab 23 which is foldable along a folding line 24 which defines the upper edge of the middle sector. At the ends of this folding line, slits 2.5, 26 are taken which extend a little along the folding line 24, in order to enable a special characteristic of the trough in the manner to be described below.

Langs trausidenes ytterkanter eller ovre kanter er det anordnet kantfliker 27, 28, som ved endene er skrått avskårne, slik at de ved reising av trauet passer til hverandre for tildannelse av Along the outer edges or upper edges of the trough sides, there are arranged edge flaps 27, 28, which are cut off at an angle at the ends, so that they fit together when the trough is erected to form

en ramme, slik som.det fremgår av fig. 2. a frame, as shown in fig. 2.

Emnet reises ved at hjornepartiene 15 brettes innover, og kantflikene 27, 28 brettes ut til et plan som i reist trau er parallell med trauets bunn. Festeflikene 23 brettes ut og over underliggende endepartier av kantflikene, og festes på disse ved forsegling ifolge valgbar kjent metode. Herved oppnås en lukket ramme med sterke skjoter ved hjornene. Ved dobbeltinnbretting av hjornepartiene, slik at sidesektorene ligger langs bakomliggende trausider, oppnås hjornestolper i trauets hjorner. Disse hjornestolper har en pyramideform med spissen vendt nedover. Ved at festefliken danner en forlengelse av resp. hjornestolpers midtseksjon og er fiksert til kantflikene ved forseglingen, kommer_hjornestolpen til å danne en stiv konstruksjon som kan oppta store be-lastninger uten å deformeres. The blank is raised by folding the corner parts 15 inwards, and the edge flaps 27, 28 are folded out to a plane which, in the raised trough, is parallel to the bottom of the trough. The attachment tabs 23 are folded out and over the underlying end portions of the edge tabs, and attached to these by sealing according to an optional known method. This results in a closed frame with strong joints at the corners. By folding in the corner sections twice, so that the side sectors lie along the rear sides of the trough, corner posts are obtained in the corners of the trough. These corner posts have a pyramidal shape with the point facing downwards. In that the fastening tab forms an extension of the resp. corner post's middle section and is fixed to the edge flaps by the seal, the corner post will form a rigid structure that can absorb large loads without being deformed.

Selvom trauet kan brukes uten nevnte slisser 25, 26, medforer disse allikevel en betydelig fordel ved at midtsektorens midtparti som ligger mellom slissenes ender (fig. 3)5 kan presses til en stilling der dette midtparti står i omtrent rett vinkel mot trauets bunn. Ellers kommer midtsektoren til å skråne innover bunnen, hvilket til en viss grad vanskeliggjør den maskinelle reis-ingen av trauet. Slissene 25,-26 muliggjor således den viste inn-trykning av midtsektoren 18, som utfores uten hjelp av ekstra brette-lin jer og oppnås under reising av trauet. De gjenstående kantpar-tier 30 av midtsektoren trykkes tett an mot de bakenforliggende sidesektorer 19, 20 og kan, om onskes, festes til disse ved forsegling. Although the trough can be used without said slots 25, 26, these nevertheless bring a significant advantage in that the middle part of the middle sector which lies between the ends of the slits (fig. 3)5 can be pressed into a position where this middle part stands at an approximately right angle to the bottom of the trough. Otherwise, the middle sector will slope inward towards the bottom, which to some extent makes the mechanical raising of the trough difficult. The slits 25,-26 thus enable the shown indentation of the middle sector 18, which is carried out without the aid of additional folding lines and is achieved during the erection of the trough. The remaining edge parts 30 of the middle sector are pressed tightly against the rear side sectors 19, 20 and can, if desired, be attached to these by sealing.

Selve lokket 31 er» som vist i; fig. 1, på sin underside forsynt med svekningslinjer 32, 33 i form av slissinnskjæringer, som har en slik dybde at de trenger gjennom plastlaget og inn i kartonglokket til en viss dybde av tykkelsen. Linjene 32, 33 loper langs lokkets kanter i en slik avstand at det gjenstår kantremser 34, 35, som har omtrent samme bredde som trauets kantfliker. Med disse kantremser festes lokket på trauets kantfliker ved forsegling, f.eks. ved påforing av limstrenger. Disse kan varmes opp straks for forseglingen, eller forseglingen kan skje umiddelbart etter an-bringelse av limstrengene, innen disse har stivnet. I stedet for spesielle limstrenger er det vanlig å direkte utnytte plastbelegget på lokket og kantremsene som bindemiddel ved varmeforsegling. The lid 31 itself is" as shown in; fig. 1, provided on its underside with weakening lines 32, 33 in the form of slotted incisions, which have such a depth that they penetrate through the plastic layer and into the cardboard lid to a certain depth of the thickness. The lines 32, 33 run along the edges of the lid at such a distance that there remain edge strips 34, 35, which have approximately the same width as the edge flaps of the trough. With these edge strips, the lid is attached to the edge flaps of the trough when sealing, e.g. when applying glue strings. These can be heated immediately before sealing, or the sealing can take place immediately after applying the adhesive strands, before these have hardened. Instead of special glue strings, it is common to directly use the plastic coating on the lid and edge strips as a binding agent for heat sealing.

Linjene 32, 33 danner to avrivningsfliker 36. Når The lines 32, 33 form two tear-off tabs 36. When

man river opp en av disse, kommer hele den innenfor forsvaknings-linjene beliggende del 37 av lokket til å rives av, mens lag av kantremsene 34, 35 blir tilbake på kantflikene og danner en ytter-ligere forsterkning av disse ved jtrauets fortsatte håndtering etter åpning. if one of these is torn open, the entire part 37 of the lid located within the weakening lines is torn off, while layers of the edge strips 34, 35 remain on the edge flaps and form a further reinforcement of these during the continued handling of the jtrough after opening .

I de tilfeller der emballasjen skal varmes opp er det hensiktsmessig å la partiene under riveflikene 36 være uforseglet, for derved å oppnå utslipningsspalter for damp, som dannes ved innholdets oppvarming. In those cases where the packaging is to be heated, it is appropriate to leave the parts under the tear tabs 36 unsealed, in order to thereby obtain escape gaps for steam, which is formed when the contents are heated.

Den utforelsesform som er vist i figurene 4 til 7, er spesielt beregnet for de tilfelle der emballasjens tetthet er spesielt betydningsfull. I denne anledning er lokket ifolge fig. 7 utformet slik at forseglingen mellom lokket og trauets kantfliker danner en sammenhengende tett ramme. Videre er trauets hjorner utformet slik at bare plastbelagte flater er vendt mot innholdet i emballasjen, til forskjell fra emballasjen i fig. 2,der innskjær-ingenes 25, 26 kanter danner frilagte snittflater som kan suge., til seg væske fra innholdet og bli misfarget, noe som er utilfredsstil-lende sett fra et estetisk synspunkt. The embodiment shown in Figures 4 to 7 is especially intended for those cases where the density of the packaging is particularly important. On this occasion, the lid according to fig. 7 designed so that the seal between the lid and the edge flaps of the trough forms a continuous tight frame. Furthermore, the corners of the trough are designed so that only the plastic-coated surfaces face the contents of the packaging, in contrast to the packaging in fig. 2, where the edges 25, 26 of the incisions form exposed cut surfaces which can absorb liquid from the contents and become discolored, which is unsatisfactory from an aesthetic point of view.

Som vist i fig. 4, er bunnen 10 og trauets sidevegger med kantfliker utfort i det vesentlige på samme måte som tilsvarende detaljer i fig. 3» Brettelinjene 37, 38 som definerer endene av As shown in fig. 4, the bottom 10 and the side walls of the trough with edge flaps are designed in essentially the same way as corresponding details in fig. 3" The fold lines 37, 38 which define the ends of

to tilgrensende siid-evegger 39, 40, danner allikevel rett vinkel med hverandre. Brettelinjene 37, 3^ begrenser i dette tilfelle et hjorneparti som ved hjelp av brettelinjer 41, 42 er inndelt i en midtsektor 43 °g to sidesektorer 44, 45• Ved enden av midtsektoren er det en boyelinje 46, langs hvilken en festeflik 47 er brettbar. Ved sine ender er festefliken 47 forbundet med kantflikene 48, 49 ved mellomliggende kantflikdeler 50, 51, hvilke er leddbart forbundet med nærliggende sidesektor langs en brettelinje 52, som kan være erstattet med en sliss for å lette brettingen, og er brettbare ved endene langs brettelinjer 53, 54 f°r reising av trauet, slik som vist i figurene 5 °g 6. two adjacent lateral side walls 39, 40 nevertheless form a right angle with each other. In this case, the folding lines 37, 3^ limit a corner section which is divided by means of folding lines 41, 42 into a central sector 43 and two side sectors 44, 45• At the end of the central sector there is a buoy line 46, along which a fastening tab 47 can be folded . At its ends, the attachment flap 47 is connected to the edge flaps 48, 49 by intermediate edge flap parts 50, 51, which are hingedly connected to the adjacent side sector along a fold line 52, which can be replaced with a slot to facilitate folding, and are foldable at the ends along fold lines 53, 54 before erecting the trough, as shown in figures 5 and 6.

Som det fremgår av fig. 5 °g 6, kommer hvert hjorne av trauet tii å ha brettede kanter 46 og 54, som således ikke oppviser noen frie--snittkanter som skal kunne suge til seg væske fra innhold.;-et i emballasjen. Videre kommer de mellomliggende kantflikdelene 51 til å bidra til å oke hjornekonstruksjonens holdfasthet og tett- As can be seen from fig. 5 and 6, each corner of the trough will have folded edges 46 and 54, which thus do not have any free-cut edges which should be able to absorb liquid from the contents of the packaging. Furthermore, the intermediate edge flap parts 51 will help to increase the holding strength of the corner structure and

kantflikene 48, 49 kommer derved til å danne en sluttet ramme som forsterker trauet. the edge flaps 48, 49 will thereby form a closed frame which reinforces the trough.

Selvom det ikke er vist på tegningen, er det klart at Although not shown in the drawing, it is clear that

forseglingen av lokket på trauets kantfliker skjer under varme og relativt hoyt trykk, slik at festeflikene 23 og 47 kommer til å the sealing of the lid on the edge tabs of the trough takes place under heat and relatively high pressure, so that the attachment tabs 23 and 47 will

presses ned til samme plan, i hvilket kantflikene er beliggende, pressed down to the same plane in which the edge tabs are located,

hvorved det lille steget mellom festeflikene og kantflikene blir praktisk talt helt utjevnet. whereby the small step between the attachment tabs and the edge tabs is practically completely smoothed out.

Om så onskes, kan emballasjen ifolge oppfinnelsen også If desired, the packaging according to the invention can also

brukes for næringsmidler som ikke skal oppvarmes, og i slike til- used for foodstuffs that are not to be heated, and in such

feller kan lokket utgjores av gjennomsiktig folie. traps, the lid can be made of transparent foil.
