Opfindelsen angår en foldeæske af den i krav l's indledning angivne art. En sådan foldeæske er kendt fra FR-pa-tentskrift nr. 2 485 486. Den kendte foldeæskes op i låget ragende sidevægpartier, der dækkes af hvert sit nedad 5 ragende randparti på foldeæskens låg, er dannet af et bånd, som er indlagt mellem bølgepappets dæklag og dets korrugerede materialelag. Det indlagte bånd holder bølgepappets dæklag adskilt fra dets korrugerede bærende materialelag, så at klaplåget kan åbnes for første gang ved, 10 at foldeæsken rives op ved hjælp af en oprivningstråd.The invention relates to a folding box of the type specified in the preamble of claim 1. Such a folding box is known from FR patent specification no. 2,485,486. cover layer and its corrugated material layer. The inlaid band keeps the cover layer of the corrugated cardboard separate from its corrugated supporting material layer, so that the flap lid can be opened for the first time by tearing up the folding box by means of a tear-off wire.

Det er besværligt og bekosteligt at indføje den kendte foldeæskes nævnte bånd mellem bølgepappets to lag under selve bølgepappets fremstilling. Bølgepap med et sådant 15 indlagt bånd kræver tidsrøvende omstilling og dermed lang stilstandstid for maskinen til pappets fremstilling, fordi det for hver foldeæskestørrelse særskilt skal fastlægges, på hvilket sted indlægsbåndet skal placeres mellem bølgepappets materialelag.It is cumbersome and expensive to insert the said band of the known folding box between the two layers of the corrugated cardboard during the manufacture of the corrugated cardboard itself. Corrugated board with such an inlaid strip requires time-consuming conversion and thus a long downtime for the machine for the production of the board, because for each folding box size it must be determined separately where the insert strip is to be placed between the material layers of the corrugated board.

Den foreliggende opfindelse har til formål at afhjælpe den ovennævnte ulempe ved den kendte teknik, og dette opnås ved det i krav l's kendetegnende del angivne. Da materialestrimmelen først fastgøres til det som sådant fær-25 dige bølgepap under selve foldeæskens fremstilling, kan foldeæskens størrelse nemt og uden supplerende omkostninger afpasses efter det pågældende behov.The present invention has for its object to remedy the above-mentioned disadvantage of the prior art, and this is achieved by the characterizing part of claim 1. Since the strip of material is first attached to the corrugated cardboard as such during the manufacture of the folding box itself, the size of the folding box can be easily and without additional costs adapted to the need in question.

Til fremstilling af foldeæsken ifølge opfindelsen kan der 30 anvendes almindeligt bølgepap uden noget mellem dets to materialelag indlagt bånd. Begge pappets materialelag overrives ved overgangen fra klaplågets randpartier til foldeæskens sidevægge, når klaplåget skal åbnes for første gang.For the production of the folding box according to the invention, ordinary corrugated cardboard can be used without any tape interposed between its two layers of material. Both material layers of cardboard are torn at the transition from the edge portions of the flap lid to the side walls of the folding box when the flap lid is to be opened for the first time.

Opfindelsen forklares nærmere i det følgende under henvisning til tegningen, hvor 35 fig. 1 viser den side af et emne til fremstilling af en foldeæske ifølge opfindelsen, der i den foldede æske dan ner dennes inderside, og 2The invention is explained in more detail in the following with reference to the drawing, in which fig. 1 shows the side of a blank for the manufacture of a folding box according to the invention, which in the folded box forms its inside, and 2

5 fig. 2 skematisk og i perspektiv viser en ved foldning af emnet ifølge fig. 1 dannet æske ifølge opfindelsen med åbnet -klaplåg.FIG. 2 shows diagrammatically and in perspective a folding of the workpiece according to fig. 1 formed box according to the invention with opened flap lid.

Den viste æske, der er dannet ved foldning af et i ét 10 stykke udformet emne af bølgepap, har fire rektangulære, gennem foldelinier med hinanden forbundne sidevægge 1, 2, 3, 4, hvoraf den med 4 betegnede har en tilgrænsende flig 5, som på den rejste æske er fastklæbet til den frie rand af den med 1 betegnede sidevæg. Sidevæggene 1-4's andre 15 rande er gennem foldelinier forbundet med tunger 6, der på den opfoldede æske danner dennes bund og topvæg 7. I sidevæggene 1, 3, og 4's område, der danner æskens øverste del, findes en oprivningslinie og på indersiden en oprivningstråd 8, der er dækket af en materialestrimmel 20 9, som strækker sig hen over alle fire sidevægge 1-4 og tungen 5, og som fra det sted, hvor de topvæggen 7 dannende tunger 6 er tilsluttet sidevæggene 1-4, strækker sig nedad forbi oprivningstråden 8, hvor den er fastklæbet til emnet som vist med skravering i fig. 1.The box shown, formed by folding a one-piece piece of corrugated cardboard, has four rectangular side walls 1, 2, 3, 4 connected by folding lines, of which the one denoted by 4 has an adjacent flap 5, which on the erected box is glued to the free edge of it with 1 designated side wall. The other 15 edges of the side walls 1-4 are connected through fold lines to tongues 6, which on the folded box form its bottom and top wall 7. In the area of the side walls 1, 3, and 4, which form the upper part of the box, there is a tear line and on the inside a tear wire 8, which is covered by a strip of material 20 9, which extends over all four side walls 1-4 and the tongue 5, and which extends downwards from the place where the tongues 6 forming the top wall 7 are connected to the side walls 1-4. past the tear-off wire 8, where it is adhered to the workpiece as shown by hatching in fig. 1.

En fyldt æske åbnes for første gang ved udøvelse af et træk i oprivningstråden 8 til dannelse af et snit i sidevæggene 2, 3 og 4 langs oprivningslinien, således at der dannes et med den fjerde sidevæg 1 svingeligt forbundet 30 klaplåg 10 omfattende topvæggen 7 og med en rundtgående rand, der, jfr. fig. 2, i lukkestillingen griber hen over materialestrimmelen 9, der rager ud over snittet i sidevæggene 2, 3 og 4 således, at der ikke kan slippe materiale ud af æsken langs snittet, når klaplåget 10 er luk-35 ket.A filled box is opened for the first time by exerting a pull in the tear wire 8 to form a cut in the side walls 2, 3 and 4 along the tear line, so that a flap lid 10 pivotally connected to the fourth side wall 1 is formed, comprising the top wall 7 and with a circumferential edge which, cf. fig. 2, in the closed position, grips over the strip of material 9 which projects beyond the cut in the side walls 2, 3 and 4 so that no material can escape out of the box along the cut when the flap lid 10 is closed.
