Vid framstallning av kanisterbottenventilsackar av papper eller liknande material bestar svarigheten i att med enkla medel tatt forsluta sackventilen ph shdant satt, att got pafyllningsgods icke kan tranga ut fran sacken, dâ denna är fylld med finkornigt gods. CLASS INTERNATIONAL SWEDISH B 31 b54 b: 4/3 PATENT AND REGISTRATION AGENCY Ans. 23./1962 on 2/3 1962How to draw a drawing J KLEIN, HOSTE eBER LENGERICH (WESTF.), FEDERAL REPUBLIC OF GERMANY Canister bottom valve bag of paper or similar material Priority requested from 4 March 1961 and 15 February 1962 (Federal Republic of Germany) canister bottom valve bag of paper or similar material. When manufacturing canister bottom valve bags of paper or similar material, the responsibility consists in closing the bag valve by simple means, provided that good filling material cannot protrude from the bag, as this is filled with fine-grained goods.

Kanisterbottenventilsackar aro redan kanda, vid vilka man i sackventilen anordnat tungformiga eller slangformiga ventilinlagg, vilka med en ande skjuta in i sackens inre for att automatiskt tillsluta den fyllda sac-ken genom trycket hos det i sacken befintliga godset mot pafyllningsventilen och mot de i sackens inre inskjutande andarna till de i sackventilen anordnade tungformiga respektive slangformiga ventilinlaggen. Canister bottom valve bags are already known, in which tongue-shaped or hose-shaped valve inserts are arranged in the bag valve, which with a spirit slide into the inside of the bag to automatically close the filled bag by the pressure of the goods in the bag against the filling valve and the inner bag. inserting the spirits into the tongue-shaped and tubular valve inserts arranged in the bag valve, respectively.

Det har emellertid visat sig, att genom dessa kanda tungformiga respektive slangformiga ventilinlagg nagon enligt nuvarande fordringar tillrackligt tat forslutning av sackventilen icke tillforsakras vid en med finkornigt gods fylld sack. Det är aven kant att anordna en ventilsack av papper eller liknande med en i ventiloppningen insatt slang, som utmarkes av att dess fritt in i sackens inre inskjutande ande är uppfransad. It has been found, however, that by means of these known heavy-shaped and hose-shaped valve inserts, according to current requirements, a sufficiently closed closure of the bag valve is not ensured in a bag filled with fine-grained goods. It is also possible to arrange a valve bag of paper or the like with a hose inserted in the valve opening, which is marked by the fact that its free spirit is inserted into the inner projecting spirit of the bag.

Darvid kunna fransarna vara krusade, de kunna vara olika langa och de kunna vara tillspetsade. Ventilsacken kan vara sh anordnad, att den i ventiloppningen inforda slangen eller atminstone dess i sa.ckens inre inskjutande ande är utf8rd av vast material, exempelvis sammet, yllevavnad eller liknande, for uppfransning eller filtning benaget material. In this case, the lashes can be curled, they can be of different lengths and they can be pointed. The valve bag may be arranged so that the hose inserted into the valve opening or at least its in the inner projecting spirit of the bag is made of solid material, for example velvet, wool wrapped or the like, material used for fringing or felting.

Men aven dessa iitgarder ha annu icke givit ett tillfredsstallande resultat med han syn till tatningen av sackventilen. Dessutom Or framstallningen av dessa kanda alltf8r komplicerade, slangformiga ventilinlagg och deras anordning i sackventilen alltfor omstandlig och darigenom forbunden med stora kostnader. But even these iitgarder have not yet given a satisfactory result with his view of the tightening of the bag valve. In addition, the manufacture of these can be too complicated, tubular valve inserts and their arrangement in the bag valve too cumbersome and thereby associated with large costs.

Detsamma galler aven for en kand ventilsack av papper eller liknande material med en slangformig och med slitsar fOrsedd inre ventilinsats av smidigt material, som uppvisar ett flertal over ventilslangens hela omkrets fordelade slitsar, vilka icke stracka sig frain till horninslagets innerkant, varvid donna anordning ãr shdan, att ventilslangen är vid sackventilens inlopp fast vid ett mot sackens inre 8ppet omslag. The same applies to a jug valve bag of paper or similar material with a hose-shaped and slotted inner valve insert of flexible material, which has a plurality of slots distributed over the entire circumference of the valve hose, which do not extend from the inner edge of the horn insert. , that the valve hose is at the inlet of the bag valve fixed to a cover against the inner 8 of the bag.

Det Or Oxen kant, att den ut ur sackventilen utskjutande anden av en i sackventilen anordnad ventilslang efter sackpafyllningen omvikes nedat for hand och ml Ores i en ficka, som är anordnad mellan den undre ventilslanghalften och det horninslag av sackbotten, som bildar ventilen for att pa detta salt tillsluta sackventilen. It Or Oxen edge, that the spirit protruding from the bag valve of a valve hose arranged in the bag valve after the bag filling is folded down by hand and ml Ores in a pocket, which is arranged between the lower valve hose half and the horn element of the bag bottom, which forms the valve to this salt close the bag valve.

Vid anvandning av dylika sackar forekommer det emellertid, att den i fickan inf8rda ventilslangsanden lamnar sitt stangda lage, emedan den fyllda sacken antager en valvd form vid det med ventilen forsedda sackhornet, vilket underlattar tillbakadragningen av den i fickan inskjutna ventilslangsanden. Dartill kommer, att omvikningen av den utskjutande ventilslangsanden och dess inf0- rande i fickan maste ske omedelhart efter bortdragningen av den fyllda sacken fran sackpafyllningens fyllningsranna, medelst vii-ken ventilsackar skola oavbrutet fyllas i mask foljd efter varandra, sh att de darmed sammanhangande handgreppen, som fordra en mycket stor manuell skicklighet, icke kunna 2— — genomforas Sorribfab• lliGt my;detta satt fii- rekommer det latt, att sackventilerna icke bli tillrackligt tatt tillslutna. When using such sacks, however, it happens that the valve hose sand inserted into the pocket leaves its closed layer, because the filled sack assumes a curved shape at the sack horn provided with the valve, which facilitates the retraction of the valve hose sand inserted into the pocket. In addition, the folding of the projecting valve hose sand and its insertion into the pocket must take place immediately after the removal of the filled bag from the filling gutter of the bag filling, by means of which valve bags must be continuously filled in mesh folded one after the other, so that the associated handles which require a very great manual skill, cannot be carried out by Sorribfab • lliGt my; this is why it is easy for the bag valves not to be adequately closed.

Dessutom upptrader den nackdelen, att for forslutningen av sackventilen erfordras en sarskild arbetskraft. In addition, there is the disadvantage that a special workforce is required for the closure of the bag valve.

Uppfinningen bar till uppgift att overvinna ifragavarande svarigheter och med speciellt enkla medel astadkomma en hattre tillslutningsverkan for sackventilen an hittills. The object of the invention was to overcome the responsibilities in question and, by means of particularly simple means, to achieve a tighter closing effect for the bag valve than hitherto.

Enligt uppfinningen bar detta problem lilsts darigenom att med kanisterbottens ventilbildande horninslag aro andarna till tva remsor av elastiskt material, sasom papper eller dylikt, UAL fastlimmade, vilka remsor med sina andra andar stracka sig ungefar fram till den mot sackens inre vanda kanten hos det horninslag till kanisterbotten, som ligger mitt emot ventilen, och remsorna aro med var sin langskant sammanthninad med tillhorande innerytor av sidoinvikningarna till sackbottnen, varvid remsornas andra langskanter liist overlappa varandra I omradet mellan de mot varandra vanda kanterna till kanisterbottens horninslag. According to the invention, this problem was alleviated by the fact that with the valve-forming horn element of the canister bottom the spirits of two strips of elastic material, such as paper or the like, UAL glued, which strips with their other spirits extend approximately to the inner edge of the horn element. the canister bottom, which lies opposite the valve, and the strips are each with their longitudinal edge joined together with associated inner surfaces of the side indentations to the bag bottom, the other longitudinal edges of the strips overlapping each other in the area between the opposite edges of the canister bottom horn.

En annan utforingsform bestfir i att tillsammans med kanisterbottens ventilbildande horninslag aro ena andarna av remsorna tatt fastlimmade, medan remsornas andra andar aro tatt fastlimmade med kanisterbottens bOrninslag, som ligger mitt emot yen-then. Another embodiment consists in that together with the valve-forming horn element of the canister bottom one of the strips of the strips is glued, while the other spirits of the strips are glued with the bore element of the canister bottom, which is opposite the yen-then.

Dessa utforingsformer kunna pa lampligt satt utvecklas, sá att remsorna besta av pap-per, som ph sina Iran den uppsparrade sackbottnen vanda sidor aro belagda med plast. These embodiments can be suitably developed so that the strips consist of paperboard, which on its Iran the uncovered sack bottom wand sides are coated with plastic.

Foremalet for uppfinningen kan vidare utformas och fOrbattras pa sadant salt, att remsornas for sackventilen anordnade andar aro gemensamt utformade till en runt om yentilkanalens inneryta forlopande forstarkningskant. The object of the invention can furthermore be designed and improved on such a salt that the spirits of the strips arranged for the bag valve are jointly formed into a reinforcing edge extending around the inner surface of the yen channel.

Derma fdrstarkningskant kan exempelvis vara utformad av en enda remsa av papper eller dylikt, som medelst limmedel är sammanlimmad med sackventilen tillhorande andar av remsorna. This reinforcing edge can for instance be formed by a single strip of paper or the like, which by means of adhesive is glued together with spirits belonging to the bag valve belonging to the strips.

En speciellt enkel och sarskilt motstandskraftig utforingsform bestar i att de sackventilen tillhOrande findarna av remsorna Aro forsedda med en gemensam omslagskant, frau vars utatriktade vikkant sfickens pafyllningsoppning utgar och vats andkant är riktad mot sackens hire. A particularly simple and particularly resilient embodiment consists in that the bag valves belonging to the fins of the strips Aro are provided with a common cover edge, from which the extended folding edge of the filling opening of the pocket extends and the spirit edge of the bag is directed towards the sac of the sack.

Harigenom uppnas att ventiloppningen blir fiirstarkt ph ett sarskilt verksamt salt, emedan det omvikta kantpartiet med sin utal riktade vikkant bildar en sarskilt motstandskraftig oppningskant till ventilen. Detta omvikningsparti kan latt framstallas maskinellt, varvid de till sackventiien hiirande remsandarna aro gemensamt omvikta till en omvikningskant, innan remsorna med det gemensamma omvikningskantpartiet vid den maski nel.la bildningen av botten inlaggas i sackens ventilbotten och darvid fastlimmas. In this way it is achieved that the valve opening becomes too strong for a particularly effective salt, since the folded edge portion with its innumerable directed folding edge forms a particularly resistant opening edge to the valve. This folding portion can be easily manufactured by machine, the strip ends belonging to the sack valve being jointly folded into a folding edge, before the strips with the common folding edge portion at the mechanical formation of the bottom are inserted into the valve bottom of the bag and thereby glued.

En annan utforingsform bestar i att de mot sackventilen vanda andarna hos de 'Ada remsorna vid fastkiistring av remsornas langskanter vid tillhOrande sidoinvikningar av sackbottnen sluta kart framfor de mot sac-hens inre vanda kanterna till sackbottnens ventilbildande horninslag och att ytorna till dessa andar pa remsorna Oro sã fastlimmade med de undre ytorna till den mat sackens inre riktade Auden av ett slangformigt ventilinlagg, att fastlimningsstallena icke omlatta remsornas varandra lOst overlappande langskanter i omradet mellan fastlimningsstallena. Another embodiment consists in the fact that the spirits of the adjacent strips wind towards the bag valve when the longitudinal edges of the strips are fastened at the corresponding lateral folds of the bag bottom, close in front of the inner wall edges of the bag bottom to form the valve base and the surfaces of these strips on the strip. so glued with the lower surfaces to the interior-directed Auden of the food bag of a tubular valve insert that the gluing stalls do not enclose the loosely overlapping longitudinal edges of the strips in the area between the gluing stalls.

Harigenom uppnas, att de mot sackventilen vanda andarna av remsorna aro med den undre ytan till den mot saekens hire riktade anden av det slangformiga ventilinlagget fast Iiirbundna med varandra till en till en viss grans elastiskt verkande enhet, varvid remsornas varandra overlappande langskanter kunna vid sitt Indian fastlimningsstallena kgande omraderiira sig nedat, dãpa- fillningsgodset strOmmar in i sacken. Pa detta satt undvikes alt de mot sackventilen vanda remsandarna icke kunna rivas sander vid den mot sackens hire riktade kanten till det ventilbildande horninslaget under paverkan av den i sacken intrangande strommen av palyllningsgods. Denna sonderrivning kan emellertid forekomma, da remsorna Oro utfOrda av ett icke tillrackligt starkt och segt papper eller dylikt och da de enskilda remsandarna aro fastlimmade omedelbart p0 kanisterbottens ventilbildande horninslag, sh att vid instromning av pafyllningsgodset i sae-ken remsorna Emma i omradet far sina Overlappande llingskanter riva solider de mot sackens inre riktade kantdelarna till Oct ventilbildande hOrninslaget i en viss grad genom avskarning. Thereby it is achieved that the spirits of the strips facing the sack valve are with the lower surface of the spirit of the tubular valve insert directed towards the sack hire fixedly connected to each other to a unit which acts elastically to a certain spruce, the overlapping longitudinal edges of the strips the gluing stalls converge downwards, the filling material flows into the bag. In this way it is avoided that the strip sands used towards the sack valve can not be torn along the edge facing the sac of the sack to the valve-forming horn element under the influence of the stream of palletizing material penetrating into the sack. However, this rupture may occur when the strips are made of an insufficiently strong and tough paper or the like and when the individual strip sands are immediately glued to the valve-forming horn part of the canister bottom, so that when the filling material flows into the strip, the strips overlap Emma. lling edges solidly tear the edge parts towards the inner part of the sack to the valve-forming corner element to Oct to a certain extent by cutting.

For att undvika att vid fyllningen av sac- ken remsornas varandra overlappande tangskanter genom den i sacken intrangande strommenpatyllningsgods utbOjas allt- fiir mycket emot sackens hire, Or det lampligt att remsornas ytor i onirialet for sina Iran shekventilen vanda andar och p0 avstand fran sina varandra lost overlappande langskanter Oro medelst smala limmaterialstallen fastlimmade -vid kanisterbottens inneryta. In order to avoid that during the filling of the sack the overlapping pliers edges of the strips through the current padding material penetrating into the sack are too much bent against the sack hire, it is appropriate that the strips' surfaces in the onirial for their Iran shek valve close spirits and at a distance from each other lost overlapping longitudinal edges Arouse by means of narrow adhesive material stacks glued -at the inner surface of the canister bottom.

Slutlitien bestar en utIOriivsform darav, att remsornas varandra lost overlappande langskanter Ore forsedda med en gemensam tvarriktningen fOrlopande inskarning ph ungeffir lika avstand Iran de mot sfickens inre riktade kanterna till kanisterbottens horninslag. Slutlitien consists of an utIOriivs form of the fact that the strips of each other loosely overlapping longitudinal edges Ore provided with a common transverse direction Continuous incision ph approximately equal distance Iran the towards the inside of the pocket to the horn elements of the canister bottom.

Harigenom uppnas alt remsornas varandra lost overlappande langskanter bli sa uppdelade av en gemensam I tvarriktningen MHO- — —3 pande inskarning, att de fran denna inskarning utgaende delarna av de varandra overlappande langskanterna kunna i viss grad vara verksamma for sig och darvid gemensamma. In this way it is achieved that the overlapping longitudinal edges of the strips become so divided by a common transverse incision MHO- - —3 panning that the parts of the overlapping longitudinal edges emanating from this incision can to some extent be active separately and thereby common.

As can be seen from Fig. 1, spirits 3 and 4 to two. strips 5 and 6 of elastic material, such as paper or the like, taken glued with a corner element 2 of the canister bottom, which form a valve. The strips extend with their other ends 7 and 8 approximately fringes to the inner wall 9 of the sickle in the opposite direction of the canal and a groove with each longitudinal edge 11 glued to the corresponding inner surfaces of the side folds 12 and 13 of the sack bottom, whereby the strips other longitudinal edges 14 and 15 overlap each other in the area between the facing edges 9 and 9 'of the corner elements 2 and 10 of the canister bottom.

I den i fig. 2 visade utforingsformen aro de ena andarna 3 och 4 av remsorna ocb. 6' tat fastlimmade vid kanisterbottens horninslag 2, som bildar ventil, medan remsornas andra andar 7' och 8' aro- tat fastlimmade vid kanisterbottens horninslag 10, som ligga mitt emot ventilen. Aven vid den i fig. 2 visade utfOringsformen aro remsorna 5' :och 6' med var sin langskant 11 fastlimmade med tillhOrande innerytor ay- sackbottnens sidoinvikningar 12 och 13, medan de andra langskanterna 14, 15 lost Overlappa varandra omradet mellan de mot varandra vanda kanterna 9 och 9' till kanisterbottens horninslag 2 och 10. For att tydligare visa de varandra overlappande kanterna 11, 15 är -1 fig. 1 ett horn ay langskanten 15 visat uppr -vikt lage. In the embodiment shown in Fig. 2, one of the spirits 3 and 4 of the strips ocb. 6 'glued to the corner member 2 of the canister bottom, which forms a valve, while the other spirits 7' and 8 'of the strips are glued to the corner member 10 of the canister bottom, which lie opposite the valve. Also in the embodiment shown in Fig. 2, the strips 5 ': and 6', each with its longitudinal edge 11, are glued with corresponding inner surfaces to the side indentations 12 and 13 of the sack bottom, while the other longitudinal edges 14, 15 loosely overlap the area between the facing the edges 9 and 9 'to the horn inserts 2 and 10 of the canister bottom. To more clearly show the overlapping edges 11, 15, in Fig. 1 a horn ay the longitudinal edge 15 is shown folded up.

I fig. 3 visas baksidorna av remsorna 5 -och 6 i fig. 1, varvid de streckade ytorna -beteckna det for fastlimning tjanande limmediet. I omradet for andarna 3 och 4 aro de varandra overlappande langskanterna 14 -och 15 hos ,de till varandra horande remsorna 5 och 6 amen limmade vid varandra. Fig. 3 shows the backs of the strips 5 and 6 in Fig. 1, the dashed surfaces denote the adhesive medium serving for gluing. In the area of the spirits 3 and 4, the overlapping longitudinal edges 14 and 15 of the adjacent strips 5 and 6 are glued together.

Fig. 4 shows the back of the strips 5 ', 6' in Fig. 2. The dashed surfaces show the adhesive which serves for gluing. In the area of the fins 3 and 4 and in the area of the spirits 7 'or 9', the overlapping tangent edges 14 and 15 of the adjacent strips 5 'and 6' are found to be glued to each other.

I fig. 5 visas sehematiskt en sektion genom ovre anden av en kanisterbottenventilsack med en genom shekbottnens sidoinvikningar 12 och 13 sluten ventilbotten, varvid en fran sackventilen utgaende ventilkanal 16 ar oppnad pa sadant salt, att den pa i och far sig kant salt kan skjutas pa pafyllningsstudsen till en sackpafyllningsmaskin. Dâ detta forlopp är i och for sig kant, visar ritningen icke sackpafyllningsmaskinen med sin utskjutande palyllningsstuds. Fig. 5 shows a section seematically through the upper spirit of a canister bottom valve bag with a valve bottom closed by the side bottoms 12 and 13 of the shekel bottom, a valve channel 16 extending from the bag valve being opened on such salt that it can be pushed on and off edge salt. the filler neck of a sack filling machine. As this process is in itself an edge, the drawing does not show the sack filling machine with its projecting pallet filling.

Fare pafyllning av sacken 1 skjutes denna med sin ventilkanal 16 pa pafyllningsstudsen till sackpafyllningsmaskinen. Vid fyllningen trycker den fran sackpilfyllningens pafyllningsranna utgaende strommen av gods ned de varandra overlappande langskanterna 14 och 15 sa langt nedat, att strommen av fyllningsgods nar in i sacken. DO sacken 1 ãr fylld och drages bort fran pafyllningsstudsen, kommer det i sacken befintliga god-set att trycka ihop remsornas 5 och 6 (fig. 1 och 3) respektive 5' och 6' (fig. 2 och 4) Ifingskanter 14 och 15, som lost lappa Over varandra i onnidet mellan de mot varandra vanda kanterna 9 och 9' till kanisterbottens hOrninslag 2 och 10, set att ventilkanalen 16 tillslutes tatt. Before filling the sack 1, it is pushed with its valve channel 16 onto the filling nozzle of the sack filling machine. During filling, the stream of goods emanating from the filling trough of the bag pile filling pushes down the overlapping longitudinal edges 14 and 15 so far downwards that the stream of filling material reaches into the bag. When the bag 1 is filled and pulled away from the filling spigot, the goods present in the bag will compress the strips 5 and 6 (Figs. 1 and 3) and 5 'and 6' (Figs. 2 and 4) respectively. , which lost patch Over each other in the onnidet between the facing edges 9 and 9 'to the corner inserts 2 and 10 of the canister bottom, seen that the valve channel 16 is closed taken.

Den tata tillslutningen av ventilkanalen tillfOrsakras darvid speciellt genom att tangskanterna 14 och 15 till remsorna 5 och 6 respektive 5' och 6' overlappa varandra over en tang stracka. The tight closure of the valve channel is thereby caused in particular by the tangent edges 14 and 15 of the strips 5 and 6 and 5 'and 6', respectively, overlapping each other over a pair of tongs.

In addition to the fold lines a — b and cd of the side folds 12 and 13, sh to ph delta set a firm, tight connection is obtained between the longitudinal edges 11 of the strips 5 and 6 and the side folds 12 and 13 of the bag bottom. The fixed, tight connection also includes the inner wall of the bag. the edge of the canister bottom's valve-forming hinge element 2. The closed valve bottom Or thereafter Closed above 1 the area for the fold lines a — b and cd.

The strips 5, 6 and 5 ', 6', respectively, separated from supply rolls of paper webs can be mechanically applied and glued to the still-opened valve bottom to the canister bottom valve bag, so that no spillage of pops arises and an overly expensive needlework is avoided.

Sasom framgar av fig. 6 Oro iindarna 3, 4 till tva remsor 5, 6 av elastiskt material, sa- som papper eller dylikt, vid en kanisterbot- tenventilsack 1 av papper eller liknande material tatt fastlimmade med ventilbildande horninslag 2 till kanisterbotten. De bada rem- sorna 5, 6 stracka sig med sina andra andar 7, 8 ungefar till den mot sackens inre vanda kanten 9 av det lairninslag 10, som ligger mitt emot ventilen. Remsorna 5 och 6 Oro med var sin langskant 11 fastlimmade med tillhorande innerytor pa sackbottnens sidoin- vikningar 12 och 13, varvid remsornas 5, 6 andra langskanter 11, 15 lost iiverlappa var- andra i omradet mellan de mot varandra vanda kanterna 9, 9' till kanisterbottnens horninslag 2 och 10.

As can be seen from Fig. 6, the inserts 3, 4 to two strips 5, 6 of elastic material, such as paper or the like, are attached to a canister bottom valve bag 1 of paper or similar material glued with valve-forming horn inserts 2 to the canister bottom. The two strips 5, 6 extend with their other spirits 7, 8 approximately to the edge 9 of the lairn weft 10, which lies opposite the valve, towards the inner water of the sack. Strips 5 and 6 Each has a longitudinal edge 11 glued with associated inner surfaces on the side folds 12 and 13 of the sack bottom, the stripes 5, 6 other longitudinal edges 11, 15 loosely overlapping each other in the area between the opposite edges 9, 9 '. to the canisters 2 and 10 of the canister bottom The spirals 3,, 4 of the strips 5, 6 arranged by the canal valve are arranged with a common folding portion X, from the outwardly directed folding edge X, the sac-hen 1 filling opening exits and whose edge L Or is directed towards the interior of the pocket.

Fig. 7 shows only the bath strips according to Fig. 6 with the common foldable edge portion, the strips Oro seen from below and whose surfaces serving for gluing aro shown streaked.

Fig. 8 är en sektion efter linjen A—B i fig. 7. Fig. 8 is a section along the line A — B in Fig. 7.

Den i fig. 6 visade fortfarande uppsparrade kanisterbottnen tillslutes p0 i och for sig kant satt genom att sackbottnens sidoinvikningar 12, 13 vikas kring vikningslinjerna - - a-b och e-d, varvid ventilbottnen tatt lirnmas vid ventiloppningen, som är anordnad i omradet for det ventilbildande harninslaget 3. The still-opened canister bottom shown in Fig. 6 is closed at a per se edge set by folding the side folds 12, 13 of the sack bottom around the fold lines - - ab and ed, the valve bottom being loosened at the valve opening, which is arranged in the area of the valve-forming hinge insert 3. .

Fig. 9 visar den slutna kanisterbottnen, varvid sackbottnens sidoinvikning 13 vikes frarst, varefter sidoinvikningen 12 irtvikes. AN detta vikningsforlopp framgar, sasom fig. 1 visar tillsammans med fig, 9, att remsans 5 langskant 11 kommer att ligga med omvikningspartiet X delvis mellan sackbottnens sidoinvikningar 13 och 12. Detta tillstand skulle naturligtvis aven erhallas, om saekbottnens sidoinvikning 13 inviktes forst och invikningen 12 darefter, varvid skillnaden endast skulle besta i att efter vikningen rernsans 6 langskant kommer att ligga med omvikningspartiet X delvis mellan sackbottnens sidoinvikningar 13 och 12. Derma utf5ringsform enligt fig. 6 och 9 kan komma till anvandning, om man sa onskar. Fig. 9 shows the closed canister bottom, whereby the side fold 13 of the sack bottom is folded first, after which the side fold 12 is folded over. From this folding process it appears, as Fig. 1 shows together with Fig. 9, that the longitudinal edge 11 of the strip 5 will lie with the folding portion X partly between the side folds 13 and 12 of the sack bottom. This condition would of course also be obtained if the side fold 13 of the sack bottom is folded first and the fold 12 thereafter, whereby the difference would only be that after the folding the long edge of the pipe 6 will lie with the folding portion X partly between the side folds 13 and 12 of the sack bottom. This embodiment according to Figs. 6 and 9 can be used, if desired.

Om det är onskvart, att vid sluten kanisterbotten nagon langskant 11 till remsan 5 respektive 6 icke Jigger mellan sackbottnens sidoinvikningar 12 och 13, kan borrningen av kanisterbottnen tillsammans med remsorna 5 och 6, vilka aro forsedda med ett gemensamt omvikningsparti X, ske pa satt som framgar av fig. 10-45. If it is desired that at the closed canister bottom no longitudinal edge 11 of the strip 5 and 6, respectively, does not jiggle between the side folds 12 and 13 of the sack bottom, the drilling of the canister bottom together with the strips 5 and 6, which are provided with a common folding portion X, can be done as is shown in Figs. 10-45.

I fig. 10 visas en dnnu uppsparrad kanisterbotten, varvid de med det gemensamma omvikbara kantpartiet X forsedda remsorna vid inlaggning i den fortfarande oppna kanisterbotten redan ha var sin omvikta tangskant 11, mot vilken den sist omvikta sidoinvikningen till kanisterbottnen ligger an. Sackbottnens sidoinvikning 13 omvikes d5.rpa forst efter vikningslinjen c-d, varvid den langskant 11, som tillhor saekbottnens sidovikning 13, kommer att ligga mot den redan omvikta langskanten 11, varefter kanisterbottnen tillslutes genom omvikning av den sist omvikbara sidoinvikningen 12, sa att en kanisterbotten enligt fig. 11 bildas, varvid flagon langskant 11 hos remsorna 5, 6 icke kommer att ligga mellan sackbottnens sidoinvikningar 12 och 13. Fig. 10 shows a still opened canister bottom, the strips provided with the common foldable edge portion X when inserted into the still open canister bottom already having their own folded pliers edge 11, against which the last folded side fold to the canister bottom rests. The side fold 13 of the sack bottom is folded d5.rpa only after the fold line cd, whereby the longitudinal edge 11, which belongs to the side fold 13 of the bag bottom, will lie against the already folded long edge 11, after which the canister bottom is closed by folding the last foldable side fold 12, so that a canister bottom Fig. 11 is formed, the flake longitudinal edge 11 of the strips 5, 6 will not lie between the side folds 12 and 13 of the sack bottom.

Samma sak kan aven astadkommas darigenom, att remsorna 5, 6 med det gemensamma omvikbara kantpar Liet X forst utformas till en for sig fardig del enligt fig. 12, vilken del darefter inlagges i ventilbotten till kanisterbottensacken, sä att den med sina langskanter kommer att ligga mellan vikningslinjerna till sackbottnens sidoinvikningar och det gemensamma omvikningspartiet darvid intager sitt riktiga lage i sackvenfilen. The same can also be achieved in that the strips 5, 6 with the common foldable edge pair Liet X are first formed into a separately finished part according to Fig. 12, which part is then inserted into the valve bottom of the canister bottom bag, so that it with its longitudinal edges will lie between the fold lines to the side folds of the sack bottom and the common folding portion thereby assumes its correct position in the sack vein file.

Efter inlaggning av delen i fig. 12 tillslutes pa i och for sig kdnt satt kanisterbottnen genom omvikning av sackbottnens sidoinvikningar 12 och 13, sa att likaledes en kanisterbotten enligt fig. 11 bildas, varvid nagon lingskant 11 hos remsorna 5 och 6 icke lig ger mellan sackbottnens sidoinvikningar 12• och 13. After inserting the part in Fig. 12, the canister bottom is closed in a per se-like manner by folding the side folds 12 and 13 of the sack bottom, so that a canister bottom according to Fig. 11 is also formed, whereby no lining edge 11 of the strips 5 and 6 lies between side folds of the sack bottom 12 • and 13.

Vidare kan samma sak aven genomfOras, om remsorna 5 och 6 med det gemensamma omvikbara kantpartiet X inlaggas pa ett sadant satt i den annu uppspdrrade kanisterbottnen, att remsorna stracka sig i sidled Over sackbottnens fOrst omvikbara sidoinvikMug sasom visas i fig. 13. I fig. 11 visas en kanisterbotten enligt fig. 13, varvid tid i fig. 14 den forst omvikta sidoinvikningen 13 till sackbottnen redan blivit vikt efter vikningslinjen c-d. Vid omvikning av sackbottnens sidoinvikning 12 efter vikningslinj en a-b komma Ifingskanterna 11 att fOrbindas pa sadant salt med varandra, att de icke ligga mellan sackbottnens sidoinvikningar 12 och 13, sasom framgar av fig. 14 i samband med fig. 15. Furthermore, the same can also be done if the strips 5 and 6 with the common foldable edge portion X are inserted in such a way in the still split canister bottom that the strips extend laterally over the first foldable side folding mug of the sack bottom as shown in Fig. 13. In fig. Fig. 11 shows a canister bottom according to Fig. 13, wherein time in Fig. 14 the first folded side fold 13 to the sack bottom has already been folded along the folding line cd. When folding the side fold 12 of the sack bottom along fold line a a b, the edges 11 will be connected to each other in such a salt that they do not lie between the side folds 12 and 13 of the bag bottom, as shown in Fig. 14 in connection with Fig. 15.

Fig. 15 visar den slutna kanisterbottnen. Fig. 15 shows the closed canister bottom.

Fig. 16 visar en fortfarande uppsparrad kanisterbotten, varvid de mot sackventilen vanda andarna 3 och 4 av de hada remsorna 5 och 6 vid fastlimning av sina langskanter 11 med tillhorande sidoinvikningar 12, 13 av sackbottnen slnta kort framfor del mot sd.e,-, kens hire Arida kantpartiet 9' av det ventilbildande horninslaget 2. Ytan pa dessa Radar 3, 4 av remsorna 5, 6 är forsedd med limmaterialstallen 19, vilka angivas med streckade ytor. Dessa limmaterialstallen 19 tjana till att forbinda ytan hos remsornas 5,6 andar 3, 4 med den undre ytan till den mot sackens inre riktade anden 17 av ett slangformigt ventilinlagg 18 pa salt, som framgar av fig. 16 i samband med fig. 17. Limnings-- stallena 19 dro sft anordnade, att de icke omfatta de lost over varandra overlappande langskanterna 14, 15 av remsorna 5, 6 i det mellan limningsstallena 19 liggande omradet Y. Fig. 16 shows a still open canister bottom, whereby the spirits 3 and 4 of the had strips 5 and 6 facing the bag valve, when gluing their longitudinal edges 11 with associated side folds 12, 13 of the bag bottom, lean briefly in front of the sd.e, -, kens hire Arida the edge portion 9 'of the valve-forming horn element 2. The surface of these Radar 3, 4 of the strips 5, 6 is provided with the adhesive material numbers 19, which are indicated by dashed surfaces. These adhesive material stalls 19 serve to connect the surface of the ends 3, 4, 4, 4 of the strips 5, with the lower surface to the spirit 17 directed towards the inner part of the bag by a tubular valve insert 18 of salt, which appears from Fig. 16 in connection with Fig. The gluing stalls 19 are arranged so as not to comprise the loosely overlapping longitudinal edges 14, 15 of the strips 5, 6 in the area Y lying between the gluing stalls 19.

Sasom framgar av fig. 17 är ytan pa. remsorna 5 och 6 i ontradet for sina fran sackventilen 18 vancla andar 7, 8 forsett Med smala limmaterialstallen 20 pa avstand och Y2 Iran remsornas lost averlappande langskanter 14, 15, sasom antydes av srafr streckade ytor 20.

As can be seen from Fig. 17, the surface is pa. the strips 5 and 6 in the ontradet for their from the bag valve 18 vancla spirits 7, 8 provided With narrow adhesive material numbers 20 at a distance and Y2 Iran the strips' loosely overlapping longitudinal edges 14, 15, as indicated by straight dashed surfaces 20. About the side folds 12; 13 to the south bottom is folded around the fold lines a-b and c-d, the surfaces of the strips 5, 6 come in the area of the Iran sack vein file. vanda spirits 7, 8 and pd. the distance and Y2 from the loosely overlapping longitudinal edges 14, 15 of the strips to be connected to the inner surface of the canister bottom by means of the narrow Ernmaterial numbers 20.

I fig. 18 visas en kanisterbotten, som ar tillsluten genom omvikning av saekbottnens sidoinvikningar 12, 13 omkring vikningslinjerna a-b och c-d (17), vilka darvid tatt limmas tram till ventilappningen 16. Fig. 18 shows a canister bottom, which is closed by folding the side folds 12, 13 of the sack bottom around the fold lines a-b and c-d (17), which are then glued to the valve opening 16.

Av fig. 19 framgar en annu uppsparrad kanisterbotten med dari fastlimmade remsor 5, 6, vilkas varandra lost overlappande tangs- 6- - kanter 14, 15 aro forsedda med en gemensam I tvarriktningen forlapande inskarning 21 pa ungefar lika avstand fran de mot sackens inre riktade kantpartierna 9, 9' hos kanisterbottnens horninslag 2 och 10. Fig. 19 shows a still open canister bottom with strips 5, 6 glued therein, the loosely overlapping pliers 6-, edges 14, 15 of which are provided with a common transverse notch 21 at approximately equal distances from those facing the interior of the bag. the edge portions 9, 9 'of the canopy bottom horn elements 2 and 10.
