Abstract

In the case of a sheet-shaped blank 1 for manufacturing the base or lid for a box, especially of cardboard or corrugated cardboard, which blank 1 comprises a rectangular, plane sheet of material, especially a sheet of cardboard or corrugated cardboard, which has fold lines 4, 5, 8, 9 parallel to the edges in order to fix two longitudinal side panels 22, 23 and two short side panels 24, 25 of the base or lid by folding at 90 degrees about the said lines, a first type of incision 10, 11, 12, 13 with a width of the same order of magnitude as the thickness of the sheet 1 being made in the parts of the short fold lines 8, 9, which lie between each of the long fold lines 4, 5, which sheet of material 1 also has some locking elements, which serve to fix the longitudinal side panels 22, 23 and the short side panels 24, 25 in their 90-degree folded position and consist partly of a second type of incision 18, 19, 20, 21 in each of the square corner flaps 14, 15, 16, 17, formed by folding over, which second type of incision is parallel with the first type of incision 10, 11, 12, 13 adjoining the corner flap and has approximately half the depth thereof, and partly of largely L-shaped cuts passing through the sheet of material in the longitudinal side panels, the first cutting line 26 of which emerges from a long fold line in the vicinity of each of the first type of incision and forms an acute angle ε with the nearest short fold line 9, 8, and the second cutting line 27 of which extends as a continuation of the first cutting line 26 in the direction away from the respective first type of incision and is approximately perpendicular thereto, two sheet-shaped blanks of slightly differing dimensions must be used for base and lid. It is therefore proposed that the edges in the first type of incision 10, 11, 12, 13 forms a small acute angle γ, and that the edge 28, which defines the side of the adjoining corner flap, forms a small acute angle γ2 with the nearest short fold line 8, 9, and that the edges 29, 30 in each of the second type of incisions 18, 19, 20, 21 likewise form a small acute angle δ. Base and lid can thereby be made of sheet-shaped blanks of uniform dimensions and still be assembled telescopically. <IMAGE>

Opfindelsen angår et arkformet emme til fremstilling af bund eller låg til en aeske, fortrinsvis af karton eller bølgepap, hvilket emne er af den i krav l's indledning angivne art.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a sheet-shaped bucket for the manufacture of a bottom or lid for a box, preferably of cardboard or corrugated board, which is of the kind specified in the preamble of claim 1.

Et arkformet emne af ovennævnte art er tidligere kendt.A sheet-shaped article of the above kind is known in the past.

5 Når man fremstiller en bund og et låg ud fra to ens arkformede emner af denne art, vil det ikke være muligt at sammenføje bunden og låget til dannelse af en æske, fordi lågets langsidefelter og især kortsidefelter ikke kan føres på plads uden på bundens tilsvarende langsidefelter og kortsidefelter.5 When making a bottom and a lid from two identical sheet-shaped items of this kind, it will not be possible to join the bottom and the lid to form a box, because the long side panels and especially short side panels cannot be inserted in place without the bottom of the bottom. long side and short side fields.

10 Det er derfor nødvendigt at fremstille bunden og låget ud fra to lidt forskelligt dimensionerede arkformede emner af denne art, hvis det færdigfremstillede låg skal blive en smule større end den færdigfremstillede bund. Dette er ikke helt tilfredsstillende, fordi arkformede emner af flere størrelser 15 kræver flere stanseværktøjer eller omstilling af et enkelt værktøj.Therefore, it is necessary to produce the bottom and the lid from two slightly different sized sheet-shaped items of this kind if the finished lid is to be slightly larger than the finished bottom. This is not entirely satisfactory because sheet-shaped items of multiple sizes 15 require multiple punching tools or the conversion of a single tool.

Arkformede emner af den omhandlede art og æsker fremstillet af sådanne emner er kendt fra trykskrifterne DK-B-151789, US-A-2488707, US-A-3226006, GB-A-2043598 og NO-PS-92487, idet 20 disse trykskrifter viser og omhandler et arkformet emne til fremstilling af bund eller låg til en æske, hvor kanterne i den første type indsnit danner en lille spids vinkel.Sheet-shaped blanks of the present invention and boxes made of such blanks are known from the printing publications DK-B-151789, US-A-2488707, US-A-3226006, GB-A-2043598 and NO-PS-92487, 20 of which are printed. shows and discloses a sheet-shaped blank for making bottom or lid into a box, the edges of the first type of incision forming a small pointed angle.

Opfindelsen har til formål at tilvejebringe et arkformet emne af den indledningsvis angivne art, som muliggør, at det samme 25 emne valgfrit kan anvendes til fremstilling af bund eller låg, og der kan klare sig med et enkelt skære- eller stanseværktøj til fremstillingen af det arkformede emne. Desuden er det et ønske, at samlingsoperationerne er så enkle, at de f.eks. kan udføres som blindearbejde. 1The invention has for its object to provide a sheet-shaped blank of the type mentioned in the preamble, which enables the same blank to be optionally used for the manufacture of bottom or lid, and can be coped with a single cutting or punching tool for the manufacture of the sheet-shaped topic. In addition, it is a wish that the assembly operations are so simple that they can, e.g. can be performed as blind work. 1

Det angivne formål opnås ifølge opfindelsen ved, at det indledningsvis angivne arkformede emne er udformet som angivet i krav l's kendetegnende del.The stated object is achieved according to the invention in that the sheet-shaped blank initially stated is designed as defined in the characterizing part of claim 1.

DK 171325 B1 2DK 171325 B1 2

Ved denne udformning af det arkformede emne opnår man, at kortsidefelterne på en af emnet fremstillet æskebund kan bringes til at hælde ind imod æskebundens indre, og at et låg, der er fremstillet af et helt tilsvarende arkformet 5 emne, kan få sine kortsidefelter indstillet således, at de kan føres ned over bunden på teleskopisk måde. Jo større de i krav l's kendetegnende del angivne små spidse vinkler y og y·^ er, jo længere kan kortsidefelterne bringes til at hælde ind mod æskebundens indre.By this design of the sheet-shaped blank, it is obtained that the short side panels of a box made of the blank can be inclined towards the interior of the box floor, and that a lid made of a completely similar sheet-shaped blank can have its short side panels set thus that they can be telescoped over the bottom. The larger the small acute angles y and y · y indicated in the characterizing part of claim 1, the longer the short side fields can be inclined towards the interior of the box bottom.

10 Hvis det enkelte L-formede snits anden snitlinie i forløbet i retning bort fra den første type indsnit danner den i krav 2 angivne lille spidse vinkel a med den nærliggende lange bukkelinie, medvirker dette også til, at bundens kortsidefelter kan bringes til at hælde ind mod bundens indre, således at deIf the second section line of the individual L-shaped section in the direction away from the first type of incision forms the small pointed angle α of the claim 2 with the adjacent long bending line, this also contributes to the short side fields of the bottom can be inclined towards the bottom of the bottom so that they

15 danner en vinkel på under 90 med bundfladen.15 forms an angle of less than 90 with the bottom surface.

Ved at frembringe den i krav 3 angivne korte snitlinie opnår man ved fremstilling af en æskebund og et æskelåg en art sammenlåsning imellem hjørnefligene og langsiderne.By producing the short section line as claimed in claim 3, a kind of interlocking between the corner tabs and the long sides is obtained by making a box bottom and a box lid.

Krav 4 angiver foretrukne værdier af vinklerne y og y^ samt 20 af vinklen δ.Claim 4 indicates preferred values of the angles γ and γ and 20 of the angle δ.

Krav 5 angiver foretrukne værdier af vinklen a.Claim 5 indicates preferred values of the angle a.

Opfindelsen angår også en fremgangsmåde til fremstilling af en æskebund samt en fremgangsmåde til fremstilling af et æskelåg ved hjælp af det arkformede legeme. Disse fremgangsmå-25 der er henholdsvis ejendommelige ved det i krav 6's og krav 7's kendetegnende del angivne.The invention also relates to a method for making a box bottom and a method for making a box lid by means of the sheet-shaped body. These methods are respectively characterized by the characterizing part of claim 6 and claim 7.

Desuden angår opfindelsen en fremgangsmåde til fremstilling af en emballage, hvilken fremgangsmåde er ejendommelig ved det i krav 8' s kendetegnende del angivne. Ved den i krav 9 30 angivne fremgangsmåde opnår man en meget sikker lukning af den ved fremgangsmåden ifølge krav 8 fremstillede emballage, DK 171325 B1 3 idet specielt de angivne bånd ved hjørnefligene tjener til at holde disses gennem lågets langsidefelter udragende dele tæt ind imod langsidefelterne, så de ikke udsættes for at ramme imod andre genstande og derved blive revet itu.In addition, the invention relates to a method of producing a package which is characterized by the characterizing part of claim 8. The method according to claim 9 30 provides a very secure closure of the packaging made by the method according to claim 8, in particular the strips indicated at the corner tabs serve to hold their portions close to the long side panels extending through the lid longitudinal panels. so that they are not exposed to hitting other objects and thereby being torn apart.

Figure 2 shows a perspective view of a box bottom made by the sheet-shaped body in a partially closed position; 2a and fig. 2b shows on a larger scale the rear right corner of FIG. 2 in partially closed position, first position, and in fully closed and locked position, second position, respectively. 3 is a perspective view of a lid made by the sheet-shaped body; FIG. 3a and fig. 3b shows, on a larger scale, the front right corner of FIG. 3 in the partially closed position, the 1st position, and in the fully closed and locked position, the 2nd position, and FIG. 4 shows a prepackaged package or box according to the invention, the closure of which is further secured by wrapping tape.

På fig. 1 ses et arkformet emne 1, som fortrinsvis består af karton eller især af bølgepap. Emnet er rektangulært og har med de lange kanter 2 og 3 parallelle bukkelinier henholdsvis 25 4 og 5 samt med de korte kanter 6 og 7 parallelle bukkelinier henholdsvis 8 og 9. I de dele af de korte bukkelinier 8, 9, som ligger imellem hver af de lange bukkelinier 4, 5 og de nærmeste lange kanter henholdsvis 2 og 3, er der fremstillet en første type indsnit 10, 11, 12, 13, således at der opstår DK 171325 B1 4 de fire hjørneflige henholdsvis 14, 15, 16, 17. I hver hjørneflig 14, 15, 16, 17 er der desuden fremstillet en anden type indsnit, henholdsvis 18, 19, 20, 21. Hver af den anden type indsnit 18, 19, 20, 21 er parallelle med det til den 5 pågældende hjørneflig tilstødende første type indsnit henholdsvis 10, 11, 12, 13 og har cirka den halve dybde heraf.In FIG. 1 shows a sheet-shaped blank 1, which preferably consists of cardboard or especially of corrugated cardboard. The blank is rectangular and has with the long edges 2 and 3 parallel bend lines 4 and 5, respectively, and with the short edges 6 and 7 parallel bend lines 8 and 9, respectively. In the parts of the short bend lines 8, 9 which lie between each of the the long bending lines 4, 5 and the nearest long edges 2 and 3, respectively, a first type of incision 10, 11, 12, 13 has been produced, so that the four corner tabs 14, 15, 16, 17 are formed respectively. In addition, in each corner tab 14, 15, 16, 17, a different type of incision is made, respectively 18, 19, 20, 21. Each of the other type of incisions 18, 19, 20, 21 is parallel to that of the 5 concerned. corner tab adjoining the first type of incisions 10, 11, 12, 13 respectively and having about half the depth thereof.

Området imellem bukkelinien 4 og kanten 2 og området mellem bukkelinien 5 og kanten 3 danner imellem de respektive første typer indsnit 10, 11 og 12, 13 to langsidefelter, henholdsvis 10 22 og 23. Området imellem bukkelinien 8 og kanten 6 og imel lem bukkelinien 9 og kanten 7 danner imellem bukkelinierne 4 og 5 to kortsidefelter henholdsvis 24 og 25. Hvert langsidefelt 22, 23 har et par L-formede snit, som går igennem materialepladen 1. Disse L-formede snit består af en første snit-15 linie 26, som udgår fra en lang foldelinie 4 eller 5 i nærheden af hvert af den første type indsnit 10, 11, 12 eller 13 og danner en spids vinkel β med den nærmeste korte bukkelinie. Desuden findes der en anden snitlinie 27, som i fortsættelse af snitlinien 26 forløber i retning bort fra den re-20 spektive første type indsnit og hen imod den nærliggende lange bukkelinie, hvormed snitlinien 27 danner en lille spids vinkel ct som vist for en af disse snitlinier 27. Vinklen mellem den første snitlinie 26 og det respektive første indsnit er vist som β for en af snitliniernes vedkommende. Som vist 25 danner kanterne i den første type indsnit 10, 11, 12 og 13 indbyrdes en lille spids vinkel y, som det fremgår af fig. 1, idet især den kant 28, som afgrænser den tilstødende hjørneflig 14, 15, 16, 17, danner en lille spids vinkel y·^ med den nærmeste korte bukkelinie 9. Dette gælder for alle fire 30 første typer indsnit 10, 11, 12 og 13 som vist på fig. 1.The area between the bend line 4 and the edge 2 and the area between the bend line 5 and the edge 3 form between the respective first types of incisions 10, 11 and 12, 13 two longitudinal fields, respectively 10 22 and 23. The area between the bend line 8 and the edge 6 and between the bend line 9 and the edge 7 forms between the bending lines 4 and 5 two short side panels 24 and 25. Each long side panel 22, 23 has a pair of L-shaped sections which pass through the material plate 1. These L-shaped sections consist of a first section 15 line 26, starting from a long fold line 4 or 5 near each of the first type of incisions 10, 11, 12 or 13 and forming a pointed angle β with the nearest short bend line. In addition, there is a second cut line 27 which, in continuation of the cut line 26, extends in the direction away from the respective first type of incision and towards the adjacent long bend line, whereby the cut line 27 forms a small pointed angle ct as shown for one of these cut lines 27. The angle between the first cut line 26 and the respective first cut is shown as β for one of the cut lines. As shown 25, the edges of the first type of incisions 10, 11, 12 and 13 form a small acute angle γ between themselves, as shown in FIG. 1, in particular the edge 28 defining the adjacent corner tab 14, 15, 16, 17 forms a small pointed angle γ · with the nearest short bend line 9. This applies to all four first 30 types of incisions 10, 11, 12 and 13 as shown in FIG. First

Kanterne 29, 30 i hvert af de andre typer indsnit 18, 19, 20 og 21 danner som vist en lille spids vinkel b på f.eks. 2 -30°. Disse kanter er for alle hjørnefligenes 14, 15, 16, 17 vedkommende betegnet 29 og 30. I hver hjørneflig - omtrent 3 5 midt på kanten 2 8 - forløber en i forhold til kantens 28 længde meget kort snitlinie henholdsvis 31, 32, 33 og 34, som DK 171325 B1 5 i det væsentlige har retning imod midten af det nærmeste L-formede snits første snitlinie 26.The edges 29, 30 of each of the other types of incisions 18, 19, 20 and 21 form, as shown, a small pointed angle b of e.g. 2 -30 °. For each corner tab 14, 15, 16, 17, these edges are designated 29 and 30. In each corner tab - approximately 35 in the middle of the edge 28 - a very short section line 31, 32, 33 and 31, 32 respectively, extends along the length. 34, which DK 171325 B1 5 is substantially oriented towards the center of the first section line 26 of the nearest L-shaped section.

På de efterfølgende fig. 2, 3 og 4 er henholdsvis vist en bund og et låg, som er fremstillet ved hjælp af det i fig. 1 5 viste arkformede emne 1 og af en emballage, som er fremstillet ved påsætning af et æskelåg på en æskebund efter sidstnævntes fyldning med varer, der skal emballeres. På disse tegningsfigurer er der anvendt tilsvarende henvisningstal som i forbindelse med tegningens fig. 1, hvor dette er muligt.In the following FIGS. 2, 3 and 4 are shown, respectively, a bottom and a lid made by means of the one shown in FIG. 1 5 and of a package made by attaching a box lid to a box bottom after the latter being filled with goods to be packaged. In these drawings, similar reference numerals have been used as in connection with the drawing of FIG. 1 where this is possible.

10 Som vist på fig. 2 er æskebunden fremstillet ud fra det arkformede emne 1 ved at de to langsidefelter 22, 23 rejses fra bunden 35 ved 90° ombukning langs de lange bukkelinier 4, 5, og at de to kortsidefelter 24, 25 rejses fra bunden 35 ved10 As shown in FIG. 2, the box bottom is made from sheet-shaped blank 1 in that the two long side panels 22, 23 are raised from the bottom 35 by 90 ° bending along the long bending lines 4, 5 and the two short side panels 24, 25 are raised from the bottom 35 by

90 ombukning langs de to korte bukkelinier 8, 9. Ved frem- 15 stilling af æskebunden bliver hjørnefligene, som det fremgår af fig. 2, udefra stukket ind i de L-formede slidser 26, 27, således at den del 36 af hver hjørneflig, der hovedsagelig er begrænset af den anden type indsnit 18, 19, 20, 21 og den yderste halvdel af den første type indsnit henholdsvis 10, 2 0 11, 12, 13 føres ind på indersiden i æskebunden. Den pågæl dende del 3 6 er på fig. 2 tydeligt vist ved langsidefeltet 22. Denne lukkestilling betegnes som 1. position. Derefter bliver kortsidefelterne 24, 25 presset ind mod æskebundens indre til maksimal ombukning, som er lidt mere end 90°, til 25 opnåelse af et automatisk låseindgreb mellem materialelagene ved delens 36 korte snitlinie 31, 32, 33, 34 og den første snitlinie 26 i den L-formede slids. Låseindgrebet betegnes som 2. position.90 folding along the two short bend lines 8, 9. In preparing the box bottom, the corner flaps, as shown in FIG. 2, projected from the outside into the L-shaped slots 26, 27, so that the portion 36 of each corner tab, which is limited mainly by the second type of notch 18, 19, 20, 21 and the outer half of the first type of notch respectively. 10, 2 0 11, 12, 13 are inserted on the inside of the box bottom. The relevant portion 36 is shown in FIG. 2 clearly shown at the longitudinal field 22. This closing position is referred to as the 1st position. Then, the short side panels 24, 25 are pressed against the interior of the box bottom for maximum bending which is slightly more than 90 ° to achieve an automatic locking engagement between the material layers at the short section line 31, 32, 33, 34 and the first section line 26 in the L-shaped slot. The locking action is referred to as 2nd position.

På fig. 2a og fig. 2b ses henholdsvis position 1 og position 30 2, og det bemærkes, hvorledes materialelagene ved delens 36 korte snitlinie 32 og den første snitlinie 26 i den L-formede slids går i låseindgreb på fig. 2b.In FIG. 2a and fig. 2b, position 1 and position 2, respectively, are seen, and it is noted how the material layers at the short section line 32 of the part 36 and the first section line 26 in the L-shaped slot are engaged in locking engagement in fig. 2b.

Fig. 3 viser, hvorledes et æskelåg fremstilles ved hjælp af DK 171325 B1 6 det arkformede emne 1. På samme måde som i forbindelse med fig. 2 rejses de to langsidefelter 22, 23 og de to kortsidefelter 24, 25 ved 90° ombukning langs henholdsvis de lange bukkelinier 4, 5 og de korte bukkelinier 8, 9. Til forskel 5 fra det på fig. 2 viste bliver hjørnefligene 14, 15, 16, 17 nu indefra stukket ind i de L-formede slidser i langsiderne 22, 23. Herved vil den del 36 af hver hjørneflig, der hovedsagelig er begrænset af den anden type indsnit 18, 19, 20, 21 og den yderste halvdel af den første type indsnit henholdsvis 10 10, 11, 12 og 13, bliver ført ud på ydersiden i æskelåget.FIG. 3 shows how a box lid is made by means of DK 171325 B1 6 the sheet-shaped blank 1. In the same way as in connection with FIG. 2, the two long side panels 22, 23 and the two short side panels 24, 25 are raised by 90 ° bending along the long bend lines 4, 5 and the short bend lines 8, 9, respectively. 2, the corner tabs 14, 15, 16, 17 are now inserted from the inside into the L-shaped slots in the long sides 22, 23. Hereby, the portion 36 of each corner tab, which is mainly limited by the second type of notch 18, 19, 20 , 21 and the outer half of the first type of incision 10 10, 11, 12 and 13, respectively, are inserted on the outside of the box lid.

Dette ses i forbindelse med langsidefeltet 23' på fig. 3. Mærket tjener til at angive, at der er tale om den modsatte side af det arkformede emne end den på fig. 1 viste. I den på fig. 3 viste lukkestilling af låget er hjørnefligene, især 15 ved langsidefeltet 22, vist i en art første lukkeposition, hvor kortsidefelterne 24, 25 skræver en lille smule udad, således at æskelåget let kan anbringes på æskebunden.This is seen in connection with the longitudinal field 23 'of FIG. 3. The mark serves to indicate that the opposite side of the sheet-shaped blank is the one shown in FIG. 1. In the embodiment of FIG. 3, the corner tabs, especially 15 at the long side panel 22, are shown in a kind of first closing position, where the short side panels 24, 25 protrude slightly outwards, so that the box lid can easily be placed on the box bottom.

Efter æskebunden er blevet fyldt med varer, der skal emballeres, påsættes det på fig. 3 viste æskelåg. Derefter trykkes 20 lågets kortsidefelter 24, 25 ind mod lågets indre til mak simal ombukning på ca. 90° til opnåelse af automatisk låseindgreb mellem materialelagene ved delens 36 korte snitlinie 31, 32, 33, 34 og den første snitlinie 26 i den L-formede slids. Hermed indtager også låget låseposition 2.After the box bottom has been filled with goods to be packaged, it is applied to FIG. 3 box cover. Then the short side panels 24, 25 of the lid are pressed against the interior of the lid for a maximum folding of approx. 90 ° to achieve automatic locking engagement between the material layers at the short section line 31, 32, 33, 34 of the portion 36 and the first section line 26 of the L-shaped slot. This also covers the locking position 2.

25 På fig. 3a og fig. 3b ses henholdsvis position 1 og position 2, og det bemærkes, hvorledes materialelagene ved delens 36 korte snitlinie 31, 32, 33, 34 og den første snitlinie 26 i den L-formede slids er gået i låseindgreb.25 In FIG. 3a and fig. 3b, position 1 and position 2 are respectively seen, and it is noted how the material layers at the short section line 31, 32, 33, 34 and the first section line 26 in the L-shaped slot are locked.

Når emballagen er blevet lukket på ovennævnte måde, kan luk-30 ningen yderligere stabiliseres ved hjælp af omsluttende bånd 37, 38 og 39 som vist på fig. 4. Båndene 37 og 39 er anbragt, så de fastholder delene 36' af de fra låget udragende hjørneflige. Båndet 38 er knap så vigtigt, men ved lange emballager kan det være hensigtsmæssigt, at emballagen har et sådantOnce the package has been closed in the above manner, the closure can be further stabilized by wrapping bands 37, 38 and 39 as shown in FIG. 4. The straps 37 and 39 are arranged to hold the portions 36 'of the corner tabs projecting from the lid. The tape 38 is hardly so important, but in the case of long packages it may be convenient for the packaging to have such a
