Fremgangsmåde til at rejse et omslag for en blokkarton i en derfor bestemt fry-serammeMethod of raising a cover for a blockboard in a therefore determined freeze frame

Den foreliggende opfindelse angår en fremgangsmåde til at 5 rejse et omslag for en blokkarton i en derfor bestemt fryseramme.The present invention relates to a method of raising a wrapper for a blockboard in a therefore determined freezer frame.

Blokkartoner anvendes til pakning af friske fødevarer før indfrysning, f.eks. inden for fiskeindustrien til ned-10 frysning af fisk eller fiskeprodukter i blokke. Blokkartonen fremstilles traditionelt i form af et plant omslag med forprægede bukkelinier. Et sådant omslag er i industrien også kendt under betegnelsen "fishblock-liner" eller "blanket". Et sådant omslag består af et bundpanel 15 med et forreste og et bageste sidepanel samt to modstående endesidepaneler, også benævnt endepaneler, hvor det bageste panel er forbundet med en side på et lågpanel, og hvor lågpanelet kan være udstyret med en eller flere klapper langs lågets øvrige sider. For at sikre en bedre 20 lukning af kartonen, når denne rejses i en fryseramme, kan sidepanelerne være forsynet med hjørnesegmenter i form af hjørneklapper fastgjort til et enkelt sidepanel, som f.eks. beskrevet i WO 97/11890. En sådan lukning af hjørnerne beskytter mod at væske render ud af den rejste 25 karton, ligesom indholdet beskyttes mod beskadigelse (frostbrand) under den efterfølgende indfrysning. De forskellige paneler er fortrinsvis forbundet med hinanden svarende til de nævnte forprægede bukkelinier. Omslaget er typisk fremstillet af flerlagets pap eller karton, der 30 kan være belagt med paraffin eller et tilsvarende materiale på den ene eller begge sider. Ved konstruktionen af omslaget er der ved valg af paraffinbelægning og ved ud- DK 173846 B1 2 formningen af de individuelle lag i pap- eller kartonma-terialet taget hensyn til, hvilken af omslagets to sider, der er bestemt som inderside på den rejste blokkarton. Et omslag for en blokkarton har derfor en forudbestemt in-5 der- og yderside.Block cartons are used for packaging fresh foods before freezing, e.g. within the fishing industry for down-10 freezing of fish or fish products in blocks. The block carton is traditionally made in the form of a flat cover with embossed bending lines. Such a cover is also known in the industry by the term "fishblock-liner" or "blanket". Such a cover consists of a bottom panel 15 having a front and rear side panel as well as two opposite end side panels, also called end panels, wherein the rear panel is connected to a side of a lid panel and the lid panel may be provided with one or more flaps along the lid. other pages. In order to ensure a better closure of the carton when raised in a freezer frame, the side panels may be provided with corner segments in the form of corner flaps attached to a single side panel, such as a side panel. described in WO 97/11890. Such a closure of the corners protects against liquids from the raised cardboard, as well as protects the contents from damage (freezing fire) during the subsequent freezing. Preferably, the various panels are connected to each other corresponding to the aforementioned embossed bending lines. The wrapper is typically made of multilayer cardboard or cardboard, which may be coated with paraffin or a similar material on one or both sides. In designing the cover, the choice of paraffin coating and the formation of the individual layers in the cardboard or cardboard material takes into account which of the two sides of the cover is determined as the inside of the erected blockboard. A cover for a blockboard therefore has a predetermined inner and outer surface.

Omslaget som beskrevet ovenfor benyttes i sammenhæng med en derfor bestemt fryseramme, der består af en ramme med sider svarende til sidepanelerne og med en åbning svaren-10 de til omslagets bundpanel. Rammen kan være udstyret med en bund, eller kan bruges på en overflade, der derved udgør en bund i rammen. Rammens indvendige sider er orienteret tilnærmelsesvis vinkelret på bunden. Når omslagets bundpanel presses ned i rammens åbning, vil sidepanelerne 15 rejses og ligge an mod rammens indersider, ligesom låget vil blive rejst til en åbentstående position. Der er herved skabt en åbentstående blokkarton. Herefter fyldes blokkartonen med den ønskede vare, f.eks. frisk fisk, hvorefter låget bøjes ned, så blokkartonen lukkes. Deref-20 ter indfryses den lukkede blokkarton i f.eks. tre timer, hvorefter blokkartonen udtages fra fryserammen, og operatøren foretager en visuel inspektion af, om kartonen er lukket korrekt, dvs. en kontrol af, om hjørneklapper og lågets sideklapper befinder sig på blokkartonens udvendi-25 ge side.The cover as described above is used in connection with a therefore determined freezing frame consisting of a frame with sides corresponding to the side panels and with an opening corresponding to the bottom panel of the cover. The frame may be provided with a base, or may be used on a surface thereby forming a base in the frame. The interior sides of the frame are oriented approximately perpendicular to the bottom. As the bottom panel of the cover is pressed down into the opening of the frame, the side panels 15 will be raised and abut against the inside of the frame, just as the lid will be raised to an open position. This creates an open block of cardboard. Then the block carton is filled with the desired product, e.g. fresh fish, after which the lid bends down so that the block box is closed. Then the sealed blockboard is frozen in e.g. three hours, after which the block carton is removed from the freezer frame and the operator performs a visual inspection of whether the carton is properly closed, ie. a check to see if corner flaps and lid flaps are on the outer side of the blockboard.

Det bemærkes, at det er vigtigt, at hjørneklapperne og lågets sideklapper befinder sig på den udvendige side af kartonen, idet man ikke ønsker disse frosset ind i fisken 30 eller tilsvarende. Dette ville medføre, at når kartonen fjernes fra den frosne vare, ville en del af kartonen, mere eller mindre synligt, kunne forblive i varen, hvad der af indlysende grunde er uønsket.It should be noted that it is important that the corner flaps and the lid flaps be on the outside of the carton, as they do not want them frozen into the fish 30 or equivalent. This would mean that when the carton is removed from the frozen product, a portion of the carton, more or less visible, could remain in the item, which is undesirable for obvious reasons.

Arbejdet med at rejse blokkartonen i fryserammen udføres 5 traditionelt manuelt, hvorved de ovenfor beskrevne fejl let kan opstå, specielt når det meget høje tempo hvorunder der arbejdes tages i betragtning. Det er dog også muligt at rejse blokkartonen maskinelt.The work of raising the block carton in the freezer frame is traditionally performed manually, whereby the errors described above can easily occur, especially when the very high tempo at which work is being taken into account. However, it is also possible to raise the blockboard by machine.

10 Problemet med at undgå at dele af blokkartonen fryses ind i fisken eller tilsvarende er forsøgt løst på forskellig måde.10 The problem of avoiding parts of the blockboard being frozen in the fish or similarly has been solved in different ways.

Fra WO 96/02422 kendes således en blokkarton som beskre-15 vet ovenfor, som er forsynet med markeringer på omslaget svarende til den foldede kartons ydersider, hvilke markeringer bliver synlige i tilfælde af en forkert lukning af blokkartonen. Ulempen ved denne blokkarton er, at den visuelle inspektion af blokkartonen først kan foretages, 20 efter at blokken udtages af den firkantede fryseramme, dvs. efter at kartonen er blevet fyldt med fisk eller tilsvarende, lukket og frosset ind. Ved fejlagtig lukning af blokkartonen er det således påkrævet, at kartonen først tømmes for fisk, hvorefter fisken skal optøs, og 25 selve fyldeprocessen foretages igen. I tilfælde af fejlagtig lukning af blokkartonen, er der således forbundet en stor arbejdsbyrde med at afhjælpe denne fejlagtige lukning. 1Thus, from WO 96/02422, a block carton as described above is known which is provided with markings on the cover corresponding to the outside of the folded carton, which markings become visible in the event of a wrong closure of the block carton. The disadvantage of this block carton is that the visual inspection of the block carton can only be carried out after the block is taken out of the square freezer frame, ie. after the carton has been filled with fish or equivalent, closed and frozen. Thus, by incorrectly closing the block carton, it is required that the carton is first emptied of fish, then the fish must be thawed and the filling process itself repeated. Thus, in the event of incorrect closure of the block carton, a large workload is associated with rectifying this erroneous closure. 1

Fra WO 97/11890 kendes en blokkarton som beskrevet ovenfor, som er forsynet med markeringer på omslaget svarende til den foldede kartons indersider, hvilke markeringer bliver synlige i tilfælde af en forkert lukning af blok- DK 173846 B1 4 kartonens hjørneklapper. Denne type af markeringer muliggør en kontrol af korrekt foldning inden kartonen fyldes, men der eksisterer stadig muligheden for, at markeringen bliver overset.From WO 97/11890 there is known a blockboard as described above, which is provided with markings on the cover corresponding to the inside of the folded carton, which markings become visible in case of incorrect closing of the corner flaps of the carton. These types of markings allow a check for correct folding before loading the carton, but the possibility of the marking being overlooked still exists.

En tredje mulighed ville være at anvende begge de ovenfor beskrevne markeringssystemer på det samme omslag, hvilket ville lette kontrol såvel under som efter arbejdets udførelse .A third option would be to use both of the marking systems described above on the same cover, which would facilitate control both during and after work.

Formålet med den foreliggende opfindelse er at tilvejebringe en fremgangsmåde som på en let og hurtig måde gør det muligt for operatøren at rejse eller folde en blokkarton af den indledningsvis nævnte art uden at hjørne-15 klapperne bliver anbragt på den indvendige side af kartonen .The object of the present invention is to provide a method which, in a light and quick manner, allows the operator to raise or fold a block carton of the type mentioned initially without the corner flaps being placed on the inner side of the carton.

Dette opnås med en fremgangsmåde, hvor der vælges et omslag, fortrinsvis belagt med paraffin på den ene eller 20 begge sider, hvor hjørnesegmenterne er fastgjort til både et endesidepanel og et tilstødende, forreste eller bageste panel, således at hjørnesegmentet foldes langs en linie udgående fra det dertil svarende hjørne af bundpanelet, når sidepanelerne rejses. En sådan udformning af 25 hjørnesegmenterne muliggør, at omslaget kan rejses i en fryseramme med kun en minimal risiko for at hjørnesegmenterne bliver anbragt på den indvendige side af den således rejste blokkarton. 1 Nærmere bestemt sikres dette ved, som' angivet i krav 1, at før omslaget presses ned i fryserammen, presses to modstående sidepaneler (enten endepanelerne eller det forreste og bageste panel) ned mod bundpanelet, hvorved hjørnesegmenterne presses ned over de dertil svarende DK 173846 B1 5 hosliggende sidepaneler, og at de to nedpressede sidepaneler rejses til anlæg mod fryserammen, efter at omslaget er blevet presset ned, fryserammen og de hosliggende sidepaneler derved rejst, hvorved hjørnesegmenterne fol-5 des og bringes til anlæg mellem sidepanelerne og fryserammen, og at hvert hjørnesegmenterne er forbundet med begge af de to tilstødende sidepaneler.This is achieved by a method of selecting a wrapper, preferably coated with paraffin on one or both sides, where the corner segments are attached to both an end side panel and an adjacent, front or rear panel so that the corner segment is folded along a line starting from the corresponding corner of the bottom panel when the side panels are raised. Such a design of the 25 corner segments allows the cover to be raised in a freezer frame with only a minimal risk of the corner segments being placed on the inside of the blockboard thus raised. More specifically, this is ensured by, as stated in claim 1, that before the cover is pressed down into the freezer frame, two opposing side panels (either the end panels or the front and rear panels) are pressed down against the bottom panel, whereby the corner segments are pressed down over the corresponding DK 173846 B1 5 adjacent side panels and the two pressed side panels are raised to abut against the freezer frame after the cover has been pressed down, the freezer frame and adjacent side panels are raised thereby filling the corner segments and bringing them into contact between the side panels and the freezer frame, and each corner segment is connected to both of the two adjacent side panels.

En korrekt rejsning af omslaget kan også sikres ved at 10 operatøren først presser hjørnesegmenterne sammen svarende til den ovenfor beskrevne foldelinie, hvad der vil bevirke, at hjørnesegmenterne foldes om ydersiden på et af de tilstødende sidepaneler.Correct erection of the cover can also be ensured by the operator first compressing the corner segments corresponding to the fold line described above, which will cause the corner segments to fold around the outside of one of the adjacent side panels.

15 Selvom de ovenfor beskrevne metoder giver en meget høj sikkerhed for korrekt rejsning af omslaget, har forsøg vist, at selv en simpel nedpresning af det plane omslag i fryserammen vil medføre, at hjørnesegmenterne med en meget stor sandsynlighed vil befinde sig på ydersiden af 20 sidepanelerne, efter at omslaget er rejst.15 Although the methods described above provide a very high degree of certainty for correct erection of the cover, experiments have shown that even a simple squeeze of the flat cover in the freezer frame will cause the corner segments to be very likely to be on the outside of the 20 side panels. , after the cover is raised.

For at sikre en let foldning af hjørnesegmentet kan dette med fordel udformes således, at hjørnesegmentet er beskåret langs dets frie rand således, at foldelinien gennem 25 hjørnesegmentet forkortes sammenlignet med et rektangulært hjørnesegment, der helt udfylder rummet mellem de to tilstødende sidepaneler.To ensure easy folding of the corner segment, this can advantageously be designed such that the corner segment is trimmed along its free edge such that the fold line through the corner segment is shortened compared to a rectangular corner segment which completely fills the space between the two adjacent side panels.

Selvom om nærværende opfindelse muliggør en meget høj 30 sikkerhed mod forkert rejsning af omslaget i fryserammen, vil forkert rejsning dog være teoretisk mulig, hvorfor omslaget med fordel kan udstyres med enten det ene eller begge af de ovenfor beskrevne markeringssystemer.However, while the present invention enables a very high degree of security against incorrect erection of the cover in the freezer frame, incorrect erection will be theoretically possible and therefore the cover may advantageously be equipped with either or both of the marking systems described above.

Alle figurer er skematiserede og ikke givetvis målfaste, og de viser kun detaljer, som er væsentlige for forståelsen af opfindelsen, mens andre detaljer er udeladt for overskuelighedens skyld. I alle figurer benyttes de samme 5 henvisningstal om de samme eller om tilsvarende dele.All figures are schematic and not obviously purposeful, and they only show details that are essential for understanding the invention, while other details are omitted for the sake of clarity. In all figures, the same reference numerals are used for the same or for similar parts.

I fig. 1 er der vist et omslag 1 for en blokkarton, før det sammenfoldes. Omslaget 1 er i den viste udførselsform fremstillet af pap, som er paraffinbelagt og indrettet 10 til at blive anvendt i forbindelse med nedfrysning af fisk.In FIG. 1, a cover 1 for a blockboard is shown before folding. In the illustrated embodiment, the wrapper 1 is made of cardboard which is paraffin coated and arranged 10 for use in the freezing of fish.

Omslaget 1 udgøres af et forreste sidepanel 2, som langs den ene side er forbundet til et rektangulært bundpanel 15 3. Bundpanelet 3 er desuden forbundet til to endesidepa neler 4, 5 og et bageste sidepanel 6. Det bageste sidepanel 6 er igen forbundet til et rektangulært lågpanel 7, som langs dets sider er forsynet med lågsideklapper 8, 9 og langs dets forreste kant er forbundet med en lågklap 20 10.The cover 1 is formed by a front side panel 2, which is connected along one side to a rectangular bottom panel 15 3. The bottom panel 3 is additionally connected to two end side panels 4, 5 and a rear side panel 6. The rear side panel 6 is again connected to a a rectangular lid panel 7, which is provided along its sides with low side flaps 8, 9 and along its front edge is connected to a lid flap 20 10.

Alle de ovenfor nævnte elementer er forbundet til hinanden svarende til forprægede bukkelinier eller såkaldte papbroer 11, som i fig. 1 er vist ved stiplede linier.All the above-mentioned elements are connected to each other corresponding to pre-embossed bending lines or so-called cardboard bridges 11, as in FIG. 1 is shown in broken lines.

25 Herved skabes der en større sikkerhed for, at blokkartonen foldes korrekt under rejsnings- eller foldningsprocessen. Afstanden mellem sidepanelernes frie kant og deres forbindelse med bundpanelet benævnes sidepanelets højde.25 This creates a greater assurance that the blockboard is folded correctly during the erection or folding process. The distance between the free edge of the side panels and their connection to the bottom panel is called the height of the side panel.

3030

Omslagets bundpanel 3 er som nævnt ovenfor forbundet med sidepaneler 2, 4, 5, 6, der i det væsentlige er rektangulære og har den samme højde. Svarende til bundpanelets hjørner er omslaget udstyret med hjørnesegmenter 14, der DK 173846 B1 8 via to papbroer er forbundet til de to tilstødende sidepaneler. Som det ses i figur 1 udfylder hjørnesegmenterne således området mellem sidepanelerne. Hjørnesegmenterne er forsynet med bukkelinier 15.As mentioned above, the bottom panel 3 of the cover is connected to side panels 2, 4, 5, 6 which are substantially rectangular and have the same height. Corresponding to the bottom panel corners, the cover is equipped with corner segments 14 which are connected to the two adjacent side panels via two cardboard bridges. Thus, as seen in Figure 1, the corner segments fill the area between the side panels. The corner segments are provided with bending lines 15.

55

Da sidepanelerne alle skal rejses til vinkelret i forhold til bundpanelet er papbroerne/ der forbinder sidepanelerne med hjørnesegmenterne, alle anbragt vinkelret på den papbro, der forbinder det enkelte sidepanel med bundpane-10 let. Hvert hjørnesegment er derfor udstyret med en bukkelinie 15, der halverer vinklen på 90° mellem de to papbroer ved hvilke hjørnesegmentet er forbundet til de tilstødende sidepaneler. Hjørnesegmenterne er i figur 1 vist kvadratiske, men de kan, som beskrevet nedenfor, være ud-15 formet på mange andre måder.Since the side panels must all be erected perpendicular to the bottom panel, the cardboard bridges / connecting the side panels to the corner segments are all arranged perpendicular to the cardboard bridge connecting the single side panel with the bottom panel 10. Each corner segment is therefore provided with a bending line 15 which bisects the angle of 90 ° between the two cardboard bridges at which the corner segment is connected to the adjacent side panels. The corner segments are shown in Figure 1 square, but as described below, they can be shaped in many other ways.

Figur 2 viser et første trin i rejsningen af omslaget.Figure 2 shows a first step in the erection of the cover.

Som markeret med pilene 100 foldes de to modstående endesidepaneler 4, 5 ned mod bundpanelet 3 af en operatør.As indicated by arrows 100, the two opposite end-side panels 4, 5 are folded down towards the bottom panel 3 by an operator.

20 Som det fremgår af figuren foldes hjørnesegmenterne sammen med sidepanelerne ned mod bundpanelet. I princippet kan i stedet for endesidepanelerne også det forreste 2 og det bageste 6 sidepanel foldes ned mod bundpanelet, men da det bageste sidepanel er forbundet til lågpanelet 7, 25 vil dette vanskeliggøre processen.20 As shown in the figure, the corner segments are folded together with the side panels towards the bottom panel. In principle, instead of the end side panels, the front 2 and the rear 6 side panel can also be folded down towards the bottom panel, but since the rear side panel is connected to the cover panel 7, this will make the process more difficult.

Figur 3 viser det næste trin i rejsningen af omslaget.Figure 3 shows the next step in raising the cover.

Som markeret med pilene 101 foldes nu det forreste og bageste sidepanel opad til en i det væsentlige vinkelret 30 position i forhold til bundpanelet. Som det fremgår af figuren medfører dette, at hjørnesegmenterne nu foldes opad sammen med det forreste og bageste sidepanel. Denne foldning finder sted ved, at operatøren presser omslagets bundpanel 3 ned i en fryseramme (ikke vist), hvorved den- DK 173846 B1 9 nes sider presser sidepanelerne opad som beskrevet. Da fryserammen har en åbning svarende til bundpanelets dimensioner, og da fryserammens indre, plane sider er orienteret vinkelret på dennes bund (eller svarende til den 5 flade, hvorpå fryserammen er anbragt) sikrer dette- at sidepanelerne rejses til vinkelret i forhold til bundpanelet .As indicated by the arrows 101, the front and rear side panels are now folded upwards to a substantially perpendicular position relative to the bottom panel. As can be seen from the figure, this means that the corner segments are now folded upwards together with the front and rear side panels. This folding takes place by the operator pushing the cover panel bottom 3 into a freezer frame (not shown), whereby the sides of the cover push the side panels upwards as described. Since the freezer frame has an aperture corresponding to the dimensions of the bottom panel, and since the interior, flat sides of the freezer frame are oriented perpendicular to its bottom (or corresponding to the surface on which the freezer frame is placed), this ensures that the side panels are raised perpendicular to the bottom panel.

Figur 4 viser det næste trin i rejsningen af omslaget.Figure 4 shows the next step in raising the cover.

10 Som markeret med pilene 102 foldes de to modstående endesidepaneler 4, 5 udad mod fryserammen (ikke vist) af operatøren til en position i det væsentlige vinkelret på bundpanelet. Som det fremgår af figuren bevirker dette, at hjørnesegmenterne foldes langs deres foldelinier 15 15 for derefter at ligge an mod sidepanelernes yderside (i forhold til den nu foldede blokkarton). I figur 5 er vist hvorledes hjørnesegmentet under sidepanelets rejsning "tvinges" til at folde og svarende til foldelinien bevæger sig væk fra det bageste sidepanel, for herefter at 20 ligge an mod ydersiden af endesidepanelet. Selvom det teoretisk er muligt, at sidepanelet rejses og føres forbi hjørnesegmentet, således at dette folder svarende til sidepanelets inderside, vil dette medføre et væsentligt større (elastisk) deformationsarbejde af sidepanel og 25 hjørnesegment, hvorfor dette i praksis stort set ikke vil ske.10 As indicated by arrows 102, the two opposite end side panels 4, 5 are folded outwardly against the freezer frame (not shown) by the operator to a position substantially perpendicular to the bottom panel. As can be seen from the figure, this causes the corner segments to be folded along their fold lines 15 and then to abut against the outside of the side panels (relative to the now folded block board). Figure 5 shows how during the erection of the side panel the corner segment is "forced" to fold and corresponding to the fold line moves away from the rear side panel, then to abut the outside of the end side panel. Although it is theoretically possible for the side panel to be raised and passed past the corner segment so that it folds corresponding to the inside of the side panel, this will result in a significantly greater (elastic) deformation of the side panel and corner segment, which is why this will practically not happen.

Herefter fylder operatøren blokkartonen med den ønskede vare, der ønskes indfrosset, f.eks. fersk fisk, hvorefter 30 blokkartonen lukkes ved at lågpanelet foldes ned og dets klapper 8, 9, 10 anbringes mellem sidepanelerne og fryse-rammen (ikke vist) . Som det ses i figur 1, strækker lågets sideklapper 8, 9 sig ikke helt ud til lågets forreste respektive bageste kant, hvorved det undgås, at side- DK 173846 B1 10 klapperne lægger sig uden på hjørnesegmenterne, hvad der ville bevirke en uønsket tyk væg i hjørnerne.Next, the operator fills the block carton with the desired item to be frozen, e.g. fresh fish, after which the block carton is closed by folding down the lid panel and placing its flaps 8, 9, 10 between the side panels and the freezer frame (not shown). As can be seen in Figure 1, the side flaps 8, 9 of the lid do not extend all the way to the front and rear edges of the lid, thereby preventing the side flaps from lying on the corner segments, which would cause an undesirable thick wall in the corners.

Figur 6 viser en fortrukken udførsel sform for et hjørne-5 segment. Hjørnesegmentet 14 er forbundet dels til et tilstødende endesidepanel 4 via en første papbro 20, dels til et tilstødende bageste sidepanel 6 via en anden papbro 21 arrangeret vinkelret på den første papbro 20 hvorved hjørnesegmentet spænder over 90°. Da de nævnte side-10 paneler har den samme højde h, er hjørnesegmentet udstyret med en bukkelinie 15, der halverer den nævnte 90° vinkel. Modsat den første papbro 20 har hjørnesegmentet en første fri kant 30, og modsat den anden papbro 21 har hjørnesegmentet en anden fri kant 31. Som det fremgår af 15 figuren er den anden frie kant 31 skråt afskåret, således at den er ikke-parallel med den modstående papbro 21, og således at den første frie kant 30 er kortere end dennes modstående papbro 20, hvorved det sikres, at hjørnesegmentets bukkelinie 15 forkortes i forhold til en situati-20 on, hvor hjørnesegmentet som et kvadrat helt udfylder området mellem de tilstødende sidepaneler. Hjørnesegmentet kunne også udformes således, at den første frie kant er skråt afskåret eller at begge frie kanter er skråt afskårne som vist i figur 7, da det væsentlige er ønsket om 25 en kortere bukkelinie 15. Dette ville også kunne sikres med et hjørnesegment, hvor papbroerne til de tilstødende sidepaneler har en udstrækning, der er mindre end sidepanelernes højde, hvad der dog vil medføre en ringere lukning af hjørnet. For at undgå, at sideklapperne lægger 30 sig uden på de foldede hjørnesegmenter, bør sideklappen anbringes på lågpanelets sidekant med en afstand a fra lågklappens sidekant 23 til det bageste sidepanel 6, der er større end højden h på sidepanelerne.Figure 6 shows a preferred embodiment of a corner 5 segment. The corner segment 14 is connected partly to an adjacent end side panel 4 via a first cardboard bridge 20 and partly to an adjacent rear side panel 6 via a second cardboard bridge 21 arranged perpendicular to the first cardboard bridge 20 whereby the corner segment spans 90 °. Since said side-10 panels have the same height h, the corner segment is provided with a bend line 15 that bisects said 90 ° angle. Opposite to the first cardboard bridge 20, the corner segment has a first free edge 30, and opposite to the second cardboard bridge 21, the corner segment has a second free edge 31. As can be seen in the figure, the second free edge 31 is obliquely cut so that it is not parallel to the the opposite cardboard bridge 21, and so that the first free edge 30 is shorter than that of its opposite cardboard bridge 20, thereby ensuring that the corner segment 15 of the corner segment is shortened relative to a situation where the corner segment, as a square, completely fills the area between the adjacent side panels. The corner segment could also be designed such that the first free edge is obliquely cut or both free edges are obliquely cut as shown in Figure 7, since it is essentially desired to have a shorter bend line 15. This could also be secured with a corner segment where the cardboard bridges for the adjacent side panels have an extent less than the height of the side panels, which, however, will result in poorer corner closure. In order to prevent the side flaps from lying on the folded corner segments, the side flap should be placed on the side edge of the cover panel at a distance a from the side edge of the cover flap 23 to the rear side panel 6 greater than the height h of the side panels.

Som beskrevet indledningsvist kan omslaget forsynes med markeringer, der muliggør en kontrol af, om blokkartonen er blevet rejst eller foldet korrekt. I figur 8 vises et omslag som vist i figur 1, men set fra undersiden. Omsla-5 get er forsynet med markeringer 40 svarende til de områder, der dækkes af hjørnesegmenterne, når omslaget er blevet foldet korrekt og som beskrevet med henvisning til figur 2 til 4. Omslaget er endvidere forsynet med markeringer 41 svarende til de områder, der dækkes af lågpane-10 lets klapper, når låget er blevet lukket korrekt med lågklapperne anbragt udenpå sidepanelerne. Da de i denne ansøgning beskrevne omslag sædvanligvis leveres med et tryk eller en udsmykning svarende til ydersiden på blokkartonen skal de beskrevne markeringer anbringes svarende til 15 denne yderside.As described initially, the cover can be provided with markings that allow a check on whether the block carton has been erected or folded correctly. Figure 8 shows a cover as shown in Figure 1, but seen from the underside. The cover is provided with markings 40 corresponding to the areas covered by the corner segments when the cover has been folded correctly and as described with reference to Figures 2 to 4. The cover is further provided with marks 41 corresponding to the areas covered. of the lid panel flaps when the lid has been properly closed with the lid flaps placed outside the side panels. Since the covers described in this application are usually supplied with a print or a decoration corresponding to the outside of the blockboard, the markings described must be placed corresponding to this outside.

Som også indledningsvist beskrevet kan omslaget svarende til den indvendige side af blokkartonen også forsynes med markeringer. Figur 9 viser et eksempel, hvor en markering 20 (42) er anbragt på den indvendige side af et hjørneseg ment, for eksempel som vist som en enkelt markering henover hjørnesegmentets bukkelinie. Dette medfører, at markeringen vil være synlig for operatøren hvis hjørnesegmentet ved en fejl skulle blive foldet ind i blokkarto-25 nen. Modsat vil en korrekt rejsning af blokkartonen med hjørnesegmentet anbragt på ydersiden af denne bevirke, at markeringen skjules.As also initially described, the cover corresponding to the inner side of the block carton may also be provided with markings. Figure 9 shows an example where a marker 20 (42) is disposed on the inner side of a corner segment, for example as shown as a single marker across the corner segment of the corner segment. This means that the selection will be visible to the operator should the corner segment be folded into the block carton by mistake. Conversely, a correct erection of the block carton with the corner segment placed on the outside of this will obscure the selection.

Der kan foretages mange ændringer, således kan markerin-30 gerne være udformet på forskellige måder. De kan f.eks. udgøres af forskellige mønstre eller farvemarkeringer, ligesom de kan have forskellig form.Many changes can be made, so markers may be designed in different ways. For example, they can are made up of different patterns or color markings, just as they may have different shapes.
