Description

Uppfinnare: R A Krauss Prioritet begard frdn den 26 september 1963 (Forbundsrepubliken Tyskland) Uppfinningen avser ett salt att framstalla en fyrkantbottnad sack, barkasse, kartong eller liknande behallare av papper, papp, vav, plast eller dylikt material, och andamhlet är framfor alit att med enkla medel astadkomma en fullstandigt tat behallarbotten med god barfOrmaga. Pt vanligt satt dubbelvikes och hopklistras behallarmaterialet till en platt tub, som utformas med balgveck mellan sidostyckenas langsgaende kanter, och det kannetecknande for det nya sattet iir, att det ena sidostycket vid ena tubanden utformas med en central flik, som stra.cker sig i tubens lingdriktning ett stycke mellan balgveckens andpartier och vars bredd i huvudsak motsvarar avstandet mellan balgveckens bottnar, att det motstaende sidostycket utformas med en mot fliken svarande urtagning, att fliken vikes over och fastes vid det motstaende sidostyckets angransande andparti, sa att tubandens centrala del tillslutes, att balgvecken appnas i huvudsak ratvinkligt mot sidostyckenas plan, att de darvid framtradande fyra hornpartierna under samtidig tillplattning am balgvecken vikas mot angransande sidostycken Mugs linjer, som stracka sig i ungefar 0 vinkel Iran andarna ay tillslutningsflikens vikningslinje mot sidostyckenas langsgaende kanter, varvid hOrnpartiernas utskjutande delar bringas att hell eller foretradesvis endast delvis overlappa den centrala tillslutningsfliken, och att det sã vikta hornpartierna fastklistras vid sidostyckenas utsidor f8r att tillsammans med sidostyckenas och balgveckens mellanliggande andpartier bilda behallarens botten. Inventor: RA Krauss Priority requested from 26 September 1963 (Federal Republic of Germany) The invention relates to a salt for producing a square-bottomed sack, launch box, carton or similar container of paper, cardboard, wrapper, plastic or the like material, and the spirit is above all to be included. simple means achieve a completely tat container bottom with good bareformage. As usual, the container material is double folded and glued together into a flat tube, which is formed with bellows folds between the longitudinal edges of the side pieces, and the characteristic of the new set is that one side piece at one tube edge is formed with a central flap extending into the tube. longitudinal direction a piece between the duct portions of the bellows fold and whose width essentially corresponds to the distance between the bottoms of the bellows fold, that the opposite side piece is formed with a recess corresponding to the flap, that the flap is folded over and fastened to the adjacent side piece the bellows folds are applied mainly at right angles to the plane of the side pieces, that the four horn portions thus protruding during simultaneous flattening of the bellows folds are folded towards adjacent side pieces Mugs lines is called to completely or preferably only partially overlap the central closing flap, and that the so-folded horn portions are glued to the outside of the side pieces to form the bottom of the container together with the intermediate end portions of the side pieces and the bellows folds.

Den fOr bottenvikningen enligt uppfinningen erforderliga utformningen am tubanden kan ske antingen fore eller efter det att materialet formats till en tub. Enligt en lamplig utforingsform, som ar tillamplig i bada dessa fall, inskaras i sidostyckena relativt korta slitsar fran ena tubariden parallellt med och intill balgveekens bottnar, varvid Ude sidostyckena forses med hiker. Den ena fliken kan sedan avskaras eller invikas i tuben, men den andra anvandes som tillslutningsflik. The design required for the bottom fold according to the invention in the tube strip can take place either before or after the material is formed into a tube. According to a suitable embodiment, which is applicable in both of these cases, relatively short slits are incised in the side pieces from one of the tubarides parallel to and next to the bottoms of the bellows, the outer side pieces being provided with hikes. One flap can then be cut or folded into the tube, but the other was used as a closing flap.

Bella}Laren kan tillverkas av ett eller flera materialskikt, och yid anvandning ay flera skikt kunna dessa pa kant satt vara stafflade vid tubandarna, sá att onocliga materialfortj ockningar ej uppkonnna i bottenpartiet. Bella} Laren can be made of one or more material layers, and when used in several layers, these can be stacked on the edge at the tube edges, so that insignificant material thickenings are not visible in the bottom part.

Sattet enligt uppfinningen beskrives nar'mare under hanvisning till bifogade ritningar, clar fig. 1 visar en perspektivbild ay en med halgveck forsedd sacktub. Fig. 1A och 1B visa modifierade utforanden av ena tubanden sedd frail sidan. Fig. 2 visar den tillplattade tuben sedd frau sidan riled bottenfliken omvikt. Fig. 2A och 2B visa modifierade utforanden, och fig. 2C visar ett speciellt forfarande i anslutning till fig. 2. Fig. 3 visar tuben i perspektiv med balgvecken oppnade och under begynnande omvikning ay hdrnpartierna. Fig. 4 visar den fardiga sacken i platt tillstand, och fig 5 visar sacken i oppnat tillstand. 1 samtliga figurer har for enkelhets skull den vid tubformningen bildade langsgaende over- Dupl. kl. 54 b: 4/ 2 lappningsfogen uteldmnats. Samma beteckningar anvandas for -mot varandra svarande delar i de olika figurerna. The set according to the invention is described in more detail with reference to the accompanying drawings, in which Fig. 1 shows a perspective view of a sack tube provided with half-folds. Figs. 1A and 1B show modified embodiments of one tube band seen frail side. Fig. 2 shows the flattened tube seen from the side riled the bottom flap folded. Figs. 2A and 2B show modified embodiments, and Fig. 2C shows a special procedure in connection with Fig. 2. Fig. 3 shows the tube in perspective with the bellows folds opened and during initial folding in the corner portions. Fig. 4 shows the finished sack in flat condition, and Fig. 5 shows the sack in opened condition. In all the figures, for the sake of simplicity, the longitudinal upper Dupl. at 54 b: 4/2 lappningsfogen uteldmnats. The same designations are used for corresponding parts in the various figures.

Den tillplattade sacktuben i fig. 1 har Iva. sidostycken 6, 7, som aro forenade medelst balgveckbildande delar 8a, b och 9a, b. Fran ena tubanden inskares i vardera sidostycket 6 resp. 7 tva. slitsar 10, 11, .som stracka sig parallellt 'med och intill balgveckens med streckade linjer 12, 13 antydda bottenkanter och darvid bilda tva andflikar 14, 15, en pa vardera sidostycket 6 resp. 7. De bada slitsarnas 10, 11 sammanlagda langd k lampligen pa sin hojd lika med avstandet mellan balgbottnarna 12, 13 och ãr foretradesvis mindre. The flattened sack tube in Fig. 1 has Iva. side pieces 6, 7, which are joined by means of bellows fold-forming parts 8a, b and 9a, b. From one of the tube bands, each side piece 6 and 6, respectively, are incised. 7 tva. slits 10, 11, which extend parallel to and adjacent to the bottom edges of the bellows folds indicated by dashed lines 12, 13 and thereby form two duct flaps 14, 15, one on each side piece 6 and 6, respectively. 7. The total length of the two slits 10, 11 is approximately equal in height to the distance between the bellows bottoms 12, 13 and is preferably smaller.

I det fall, att tuhamnet bestar av flera materialskikt, kunna dessa pa kant satt vara »stafflade» vid tubanden, sasona antydes i fig. IA, ddr det ovre sidostycket är visat i tre trappstegsformigt avskurna skikt 6a, 6b, 6c. Fig. IB visar det modifierade utfOrandet, att ena andfliken 15' dr nagot forlangd i forhallande till tubanden i ovrigt. Ev kunna hada andflikarna vara forlangda. Aven här kan givetvis staffling forekoinma, dâ flera materialskikt anvandas. In the case that the tuhamnet consists of several material layers, these can be "staffed" on the edge at the tube bands, as indicated in Fig. 1A, where the upper side piece is shown in three stepped layers 6a, 6b, 6c. Fig. 1B shows the modified embodiment, that one of the duck flaps 15 'is somewhat required in relation to the other tube band. Possibly the duck flaps may be required. Here, too, of course, staffing can occur, when several layers of material are used.

I ett nasta arbetsmoment vikes den ena and-'liken 14 Mat langs den streckade linjen 16 i fig. 1 samt fastklistras vid insidan av ettdera sidostycket 6 eller 7. I manga fall torde det emellertid vara enklare och lika fordelaktigt att avskka fliken 14 langs linjen 16. Harefter omvikes den andra fliken 15 Over det motstaende sidostycket 6 langs samma linje 10 samt fastklistras vid styckets 6 utsida, sasom visas i fig. 2, varigenom tubandens mittparti blir tillslutet. Om den i fig. 1B visade forlangda andfliken 15' anvandes, blIr forbindningen ytteriigare fOrstarkt, men i regel torde detta ej mama. nodvandigt. For att underlatta den i det foljande beskrivna arbetsoperationen kan den fortfarande platt liggande tuben dessutom genom pragling forses med bigningslinjer 17 (fig. 2), som stracka sig frau slitsarnas 10, 11 innerandar, dvs. frau vikningslinjen 16, diagonalt utat mot tubens langsgaende kanter. In a next working step, one and the like 14 Mat is folded along the dashed line 16 in Fig. 1 and glued to the inside of either side piece 6 or 7. In many cases, however, it should be simpler and equally advantageous to cut off the flap 14 along the line. 16. Then the second flap 15 is folded over the opposite side piece 6 along the same line 10 and glued to the outside of the piece 6, as shown in Fig. 2, whereby the middle part of the tube band is closed. If the required duck flap 15 'shown in Fig. 1B is used, the connection will be further strengthened, but as a rule this should not be the case. necessary. In order to facilitate the working operation described in the following, the still flat tube can also be provided by bending with bending lines 17 (Fig. 2), which extend from the inner ends of the slots 10, 11, i.e. frau fold line 16, diagonally outward toward the longitudinal edges of the tube.

Fig. 2A visar en speciell staffling, som kan vara lamplig for undvikande av onodiga materialfOrtjockningar vid foljande bottenvikning. De utanfor slitsarna 10, 11 belagna delarna av sidostyckena 6, 7 ha Ur bortskurits (vid 18) i linje med fOrslutningsflikens 15 vikningslinje 16, sa att endast de balgbildande delarna 8a, b och 9a, b utskjuta yid tubanden. Denna bortskarning kan crenomforas ndr som heist under hittills beskrivna arbetsmoment men sker foretradesvis i samband med slitsarnas 10, 11 utformning. Fig. 2B antyder en nagot modifierad staining, i (let att snittlinjerna 18' ej stracka sig anda fram till tubens langsgaende kanter, utan smala remsor 19 ay sidostyckena 6, 7 kvarlamnats narmast balgvecken. Fig. 2A shows a special staffing, which can be suitable for avoiding unnecessary material thickenings in the subsequent bottom folding. The parts of the side pieces 6, 7 coated outside the slots 10, 11 have been cut away (at 18) in line with the folding line 16 of the closure flap 15, so that only the bellows-forming parts 8a, b and 9a, b project beyond the tubing. This cut-off can be crenomforated as lifted during the work steps described so far, but preferably takes place in connection with the design of the slots 10, 11. Fig. 2B indicates a slightly modified staining, in that the section lines 18 'do not extend to the longitudinal edges of the tube, but narrow strips 19 in the side pieces 6, 7 are left closest to the bellows folds.

Med undantag fOr det fall, att hela tubmaterialet eller erforderliga delar av detsamma Or sjalvklistrande (em. mid um:oval-inning under tryck), palores vid lamplig tidpunkt ett bindenaedel pa de ytdelar, som sedan skola hopklistras med varandra. SMunda inf Ores bindemedel Indian de utanfor bigningslinjerna 17 liggande delarna am balgveckens 8, 9 och sidostyckenas 6, 7 insidor, och vid'are pdfores bindemedel pa de utanfor bigningslinjerna 17 liggande delarna av sidostyckenas 6, 7 utsidor. Vid utforandena i fig. 2A och 2B Wines da. samtidigt bindemedel pa de genom staffingarna blottade delarna av .balgvecken. Ev. kunna hela de i fig. 2C antydda, punkterade delarna am tubens bada utsidor beliggas med bindemedel. With the exception of the case where the entire tube material or required parts of the same are self-adhesive (em. Mid um: oval-in under pressure), a binder part is palored at the appropriate time on the surface parts, which are then to be glued together. SMunda inf Ores binder Indian the parts outside the curvature lines 17 on the insides of the bellows folds 8, 9 and the side pieces 6, 7, and further adhesive is applied on the parts outside the curvature lines 17 lying on the sides of the side pieces 6, 7. In the embodiments of Figs. 2A and 2B, Wines da. at the same time adhesive on the parts of the bellows folds exposed by the staffings. Ev. the entire punctured parts of the tubes' outer surfaces indicated in Fig. 2C can be covered with adhesive.

I 'foljande arbetssteg (fig. 3) Oppnas de hada balgvecken genom att de balgbildande delarna 8a, b och 9a, b jamte angransande delar av sidostyckena 6, 7 bops i ungefar rat vinkel mot sidostyckenas fortfarande platt liggande mittdelar, varvid tuben far en H-formig tvarsektion. Vid vardera balgvecket vikas nu de bada utanfor bigningslinjerna 17 belagna hornpartierna 20 inat mot angransande delar av sidostyckena 6, 7, samtidigt som balgvecken 8, 9 successivt ater tilIplattas, i den man som vikningen fortskrider. Vid dessa kombinerade vikningsoperationer bliva de i harnpartierna ingaende delarna ay balgvecken bucklade ut och in omkring punkter 21, som. Oro beld.gna vid bottenvikningslinjens 16 andar, och hOrnpartiernas rektangulka, utskjutande delar bringas darvid att falla Over och tacka bottenflikens 15 intilliggande delar. Efter hornpartiernas fastklistring har den tillplattade behallaren det i fig. 4 visade utseendet. Sasom synes overlappa hornpartiernas rektanguldra ytterdelar den centrala bottenflikens 15 kantpartier under bildning am tvargaende forstarkningar, som stracka sig Over bottnens hela bredd och darvid bilda en effektivt tatande bottenforslutning. In the following working step (Fig. 3), the hot bellows folds are opened by baffling the bellows-forming parts 8a, b and 9a, b and adjacent parts of the side pieces 6, 7 at approximately an angle to the still flat middle parts of the side pieces, the tube having an H -shaped cross section. At each bellows crease, the two horn portions 20 coated outside the curvature lines 17 are now folded inwards towards adjacent parts of the side pieces 6, 7, at the same time as the bellows creases 8, 9 are gradually flattened again, in the man as the folding progresses. In these combined folding operations, the parts entering the urethral portions ay the bellows folds dented in and out around points 21, which. Concerns about the spirits of the bottom fold line 16, and the protruding parts of the corner portions of the corner folds are thereby caused to fall over and thank the adjacent parts of the bottom flap 15. After the horn portions have been glued on, the flattened container has the appearance shown in Fig. 4. As if the rectangular outer parts of the horn portions appear to overlap the edge portions of the central bottom flap 15 during formation with transverse reinforcements, which extend over the entire width of the bottom and thereby form an effective sealing bottom closure.

Behallaren Or visad i uppfallt lOge i fig. 5. Tva motstaende kanter hos dien rektangulara bottnen ha utbildats langs de omvikta hornpartiernas 20 tvargiende kanter 22 i fig. 4, och de hada andra bottenkanterna ha uppkommit genom att balgvecken vikts langs en i fig. 3 antydd linje 23. mom ramen for uppfinningen kunna slitsarna 10, 11 gOras sa langa, att de utanfor bottenvikningslinjen 16 utskjutande delarna ay hknpartierna 20 i behallarens fardiga till-stand tangera varandra yid mitten av botten- a fliken 15, vilken i sh fall blir hell tackt. Ett sadant utforande är dock ingalunda nodvandigt for erhallande av en botten med god hallfasthet, och sannolikt ar det ej ens att fore: draga. The container Or is shown in a striking position in Fig. 5. Two opposite edges of the rectangular bottom have been formed along the transverse edges 22 of the folded horn portions 20 in Fig. 4, and the other bottom edges have arisen by folding the bellows folds along one in Fig. 3. According to the invention, the slits 10, 11 can be made so long that the parts projecting outside the bottom folding line 16 at the corner portions 20 in the finished condition of the container touch each other in the middle of the bottom a flap 15, which in this case becomes smooth. thank you. However, such a design is by no means necessary for obtaining a bottom with good half-strength, and it is probably not even preferable.

Den i fig. 1, 1A eller 1B visade tuben kan pa vanligt satt framstallas av en audios materialbana i en s. k. tubformningsmaskin, och for utforande av den beskrivna bottenforslutningen kan antingen tubformningsmasIdnen kompletteras med erforderliga vikningsmekanismer, eller ocksa kan en sarskild bottenlaggningsmaskin anvandas. The tube shown in Figs. 1, 1A or 1B can usually be produced from an audio web of material in a so-called tube forming machine, and for performing the described bottom closure either the tube forming machine can be supplemented with the required folding mechanisms, or a special bottom laying machine can be used.
