Description

Uppfinnare: C Hasler, A Dreyer och M de Toledo Prioritet begard frdn den 27 augusti 1953 och den 2 mars 1954 (Schweiz) Foreliggande uppfinning avser ett tatt slutande emballage eller en forpackning, speciellt lampligt f8r flytande och gasformiga amnen, av en typ, som bestar av en behallare, exempelvis en sack av ett mjukt, plastiskt eller termoplastiskt amne, som har en oppning f8rsedd med en. sjalvforslutningsventil bestaende av en tillplattad ledning och i stand att kurma oppnas genom inforande i namnda ledning av ett ror, exempelvis ett stelt ror av cylindrisk eller konisk form, varvid ledningen vanligen bildas antingen av ett tillplattat rOr eller av tva trama sldvor, som aro hoplodda med varandra vid sina kanter. Inventors: C Hasler, A Dreyer and M de Toledo Priority claimed from 27 August 1953 and 2 March 1954 (Switzerland). The present invention relates to a tightly closed package or package, particularly suitable for liquid and gaseous substances, of a type which: consists of a container, for example a sack of a soft, plastic or thermoplastic blank, which has an opening provided with a. self-closing valve consisting of a flattened pipe and capable of curvature is opened by inserting in said pipe a pipe, for example a rigid pipe of cylindrical or conical shape, the pipe usually being formed either by a flattened pipe or by two tram rails, which are soldered together with each other at their edges.

Erfarenheten har visat, att sadana ventiler icke med sakerhet forhindra framsipprandet av ett fluidnm, t. ex. en vatska, pa grund av kapillarverkan, som uppkommer darigenom, att vatskan kan komma in och stanna kvar mellan ventilens kanter vid sackens pafyllning. Experience has shown that such valves do not reliably prevent the leakage of a fluid, e.g. a liquid, due to the capillary action, which arises from the fact that the liquid can enter and remain between the edges of the valve when filling the bag.

Foreliggande uppfiiming har till uppgift att avhjalpa nyssnamnda oldgenhet. Emballaget eller forpackningen, som utgor foremalet for uppfinningen, kannetecknas darav, att den tillplattade ledningen bildas av tva. vaggar, soin var och en bestar av tva mot varandra vettande delar, vilka var och en standigt aro anbragta mot motsvarande del av den andra vaggen, varjamte det bestar av en anordning, som hailer ledningens vaggar atskilda frail varandra pa en del av ledningen p& sadant satt, att atmins tone i en av vaggarna bildas ett veck, som &Mier halla ventilen stangd vid dess inre ande, oberoende av trycket i behallaren. The object of the present invention is to remedy the aforementioned antiquity. The package or packaging which forms the object of the invention can be characterized in that the flattened line is formed by two. cradles, each of which consists of two facing parts, each of which is permanently arranged against the corresponding part of the other cradle, and it consists of a device which holds the cradles of the conductor separately from each other on a part of the conduit in such sat, that atmins tone in one of the cradles formed a fold, which & Mier keep the valve closed at its inner spirit, independent of the pressure in the container.

Namnda anordning underlattar lokaliseringen av oppningen, da man onskar infora ett f8rbindelseror for pafyllning eller thinning av behallaren, sarskilt om detta inf5rande av roret sker i m6rker. Said device facilitates the location of the opening, as it is desired to insert a connecting pipe for filling or thinning the container, especially if this insertion of the pipe takes place in the dark.

Anordningen kan utformas och dimensioneras pa olika salt sasom I det f8ljande beskriyes utan att man darfor frangar uppfinningens princip. The device can be designed and dimensioned on different salts as described in the following without departing from the principle of the invention.

Fig. 1, 2 och 3 visa en forsta utfOringsform, som omfattar en behallare bildad air en sack 1 av ett mjukt material, exempelvis av plast eller kautschuk, och en ledning 6 for pafyllning och thinning. Behallaren Or bildad av ett ror av mjuld material. Ledningen 6 är fast vid Ovre oppningen pa behallaren 1 medelst svetsfogar 5, vilka tillsluta behallaren vid dess ovre dude och vilka avenledes delvis tillsluta ledningen 6. Denna bildas av tva holier av ett termoplastiskt amne, som Oro forenade med varandra utefter sina langsgaende kanter medelst svetsfogarna 9. Dessa svetsfogar stracka sig parallellt med varandra vid kanterna av ledningen 6, sit att pit denna bildas en fortrangning av svetsfogen 5. Ledningen 6 Or forsedd med ett munstycke 15, som Or inpressat i den passage, som lamnats oppen air svetsfogarna 2— — 5. Detta munstycke har formen av en liten tratt. Sasom framgar av fig. 2, underlattar detsamma inforandet tvars genom ledningen 6 och anda tram till det inre av behallaren 1 av ett rar 4 fOr pafyllning och tomning. Genom att halla vaggarna i ledningen 6 atskilda fran varandra pa ett stycke av ledningen vid inloppet till behallaren astadkommer munstycket 15 bildandet i ledningens 6 vaggar av vecken 16, som stra.va att liana ledningen tillsluten vid dess inre ande, oberoende av det i behallaren radande trycket. Figs. 1, 2 and 3 show a first embodiment, which comprises a container formed in a sack 1 of a soft material, for example of plastic or rubber, and a conduit 6 for filling and thinning. The container Or formed from a rudder of soft material. The conduit 6 is fixed to the upper opening of the container 1 by means of welds 5, which close the container at its upper dude and which in turn partially close the conduit 6. This is formed by two envelopes of a thermoplastic blank, which Oro joined together along their longitudinal edges by the welds 9. These welds extend parallel to each other at the edges of the conduit 6, so that this is formed a constriction of the weld 5. The conduit 6 is provided with a nozzle 15, which Or is pressed into the passage left open by the air welds 2— - 5. This nozzle has the shape of a small funnel. As shown in Fig. 2, the same facilitates insertion across the conduit 6 and breathing tram to the interior of the container 1 by a tube 4 for filling and emptying. By keeping the cradles in the conduit 6 separated from each other by a piece of the conduit at the inlet to the container, the nozzle 15 causes the formation in the cradles of the conduit 6 of the folds 16, which strive to line the conduit closed at its inner spirit, independent of the container radiating the pressure.

Efter palyllningen av behallaren. 1 tillslutes dess pfifyllnings- och avtappningsledning vid munstycket 15, sã att densamma air hygleniska skill blir skyddad mot damm. Sasom visas i fig. 1, sakerstalles denna tillslutning air en membran 17, som är fastlimmad eller fastlodd vid de yttre kanterna av munstycket 15. DA. man Onskar avtappa vatska fran behallaren 1, borttages eller sonderrives forst membranen 17 exempelvis genom att blott inf6ra roret 4 i munstycket 15. After filling the container. 1, its filling and draining line is closed at the nozzle 15, so that the same hygienic partition is protected against dust. As shown in Fig. 1, this closure is stored in a membrane 17, which is glued or soldered to the outer edges of the nozzle 15. DA. If it is desired to drain liquid from the container 1, the membranes 17 are first removed or torn apart, for example by simply inserting the tube 4 into the nozzle 15.

Det ma framhallas, att en membran siidan som membranen 17 i stallet for att anbringas pa munstycket 15 efter pafyllningen av behallaren aven kan tillverkas tillsammans med namnda munstycke och anbringas antingen utanpa detta, sasom visas i fig. 1, eller pa munstyckets >hals> 18 eller slutligen vid dess inre ande. Pafyllningen air behallaren sker dã, innan munstycket 15 anbringats vid mynningen av ledningen 6 och munstycket fastes vid namnda mynning medelst limning eller svetsning efter pfifyllning av behallaren. Det är likaledes mojligt att tillverka ledningen 6 och munstycket 15 i ett enda stycke. It should be noted that a membrane other than the membranes 17 in the stable to be applied to the nozzle 15 after filling the container can also be made together with said nozzle and applied either outside it, as shown in Fig. 1, or on the nozzle> neck> 18 or finally by its inner spirit. The filling of the container takes place then, before the nozzle 15 is applied at the mouth of the line 6 and the nozzle is fixed at said mouth by gluing or welding after filling of the container. It is also possible to manufacture the line 6 and the nozzle 15 in a single piece.

En andra utfOringsform, som visas i fig. 4, shiljer sig fran den forsta darigenom, att den anordning, som hailer vaggarna av ledningen 6 vid dennas vid oppningen till behallaren 1 fasta ande atskilda, bestar am tva tunna remsor 20 och 21, som var och en har ett ombojt mittparti 22. Dessa tva. remsor arc sammanfogade med varandra °eh bilda den ovre kanten air behallaren 1, varvid deras ombojda delar 22 aro placerade mitt emot varandra och bilda de tva motsatta kanterna till ingangsOppningen pa ledningen 6. A second embodiment, shown in Fig. 4, differs from the first in that the device which holds the cradles of the conduit 6 at its fixed end at the opening to the container 1 consists of two thin strips 20 and 21, which were and one has a folded middle section 22. These two. strips arc joined together to form the upper edge of the air container 1, their bent parts 22 being placed opposite each other and forming the two opposite edges of the entrance opening on the conduit 6.

Remsorna 20 och 21 kunna bildas genom en forstarkning av behallarens kanter eller air tva tunna platar, exempelvis av ett plastiskt material eller av ett annat material, som liar en Ass styvhet, och vilka platar aro limmade eller svetsade pa den ovre delen av behallaren. Fairet 4 kan inforas I behallaren tvars genom ledningen 6 genom att fora detsamma mellan de bojda delarna 22 pa skivorna 20 och 21. The strips 20 and 21 may be formed by a reinforcement of the edges of the container or two thin plates, for example of a plastic material or of another material which has an rigidity, and which plates are glued or welded to the upper part of the container. The fairing 4 can be inserted into the container transversely through the conduit 6 by passing the same between the bent parts 22 on the discs 20 and 21.

Fig. 5 visar en tredje utf6ringsform, vid vilken den anordning, som hailer vaggarna till ledningen 6 atskilda pa det stalle dar denna är ansluten till behallaren 1, bildas av en ring 23, som fir infast mellan kanterna till namnda lednings yttre dude. Denna ring kan tillverkas ay ett plastiskt eller annat material samt limmas eller loclas fast vid ledningens mynning. Fig. 5 shows a third embodiment, in which the device which holds the cradles to the conduit 6 separated at the place where it is connected to the container 1, is formed by a ring 23, which is fixed between the edges of the outer dude of said conduit. This ring can be made of a plastic or other material and glued or laced to the mouth of the pipe.

En fjarde utforingsform, som visas i fig. 6, bestar likaledes av ett munstycke 15 i form av en tratt. Detta munstycke fir vid sin yttre andc forsett med en runt om gaende flans 24, som forhindrar detsamma att glida ut ur ledningen G. Liksom vid den tredje utfOringsformen är munstycket 15 limmat eller svetsat vid kanterna av mynningen till ledningen 6, men tack vare flansen 24 kan det ej dragas bort fran namnda mynning, fiven om det skulle lossna eller losgoras fran namnda kanter. A fourth embodiment, shown in Fig. 6, likewise consists of a nozzle 15 in the form of a funnel. This nozzle is provided at its outer end with a circumferential flange 24, which prevents it from sliding out of the conduit G. As in the third embodiment, the nozzle 15 is glued or welded at the edges of the mouth to the conduit 6, but thanks to the flange 24 it cannot be pulled away from said mouth, fiven if it should come loose or detach from said edges.

Den inre anden av munstycket 15 Ad den fjarde utforingsformen har en forlangning, som blir alit trangre anda fram till dess inre ande och bildar elastiska lappar 25, vilka kunna antingen vara i kontakt med varandra eller vilolage vara latt atskilda. Vid inforandet av ett r6r 4 tvars genom ledningen 6 och genom munstycket 15 sluta sig lapparna 25 kring roret 4, sa att en tat fog bildas mellan detta munstycke och namnda ror, sa att varje aterstrOmning av vatska mellan roret och munstycket forhindras. The inner spirit of the nozzle 15 In the fourth embodiment has a desire which becomes a narrower spirit up to its inner spirit and forms elastic patches 25, which can either be in contact with each other or rest layers be easily separated. When a pipe 4 is inserted transversely through the line 6 and through the nozzle 15, the flaps 25 close around the pipe 4, so that a joint is formed between this nozzle and said pipe, so that any flow of liquid between the pipe and the nozzle is prevented.

En forlangning, som bildar elastiska lap-par liknande lapparna 25 i fig. 6 skulle likaledes kunna anordnas yid vilken som heist av de ovan beskrivna utforingsformerna for att bilda en fog, som fOrhindrar varje aterstrOnining av vatska mellan palyllningsr5ret 4 och mynningen till ledningen 6. Vid de fernte och sjatte utforingsformerna, som visas i fig. 7 resp. 8, lianas vaggarna till ledningen 6 tatt mot varandra vid tva mot varandra beldgna delar, en pa vardera sidan av ledningens langdaxel, medelst svetsfogarna 9. I det fall, da ledningen 6 bildas av ett tillplattat riir och ej av tva pa varandra lagda skivor tjana .salunda svetsfogarna 9 pa. samma satt att halla ledningens vaggar tatt mot varandra, varvid ledningens kanter icke aro sammansvetsade i langdriktningen. Svetsfogarna 9 bidraga i forening med den anordning, som vaggarna till ledningen 6 skilda Iran varandra vid ledningens tilloppsande, att bilda ett veck 16 i vardera ledningsvaggen. Vid den femte utforingsformen, som visas i fig. 7, utbreda sig svetsfogarna 9 vinkelratt mot kanterna av ledningen 6, under del ett svetsfogarna 9 vid den i fig. 8 visade sjatte utforingsformen var och en ha formen ay ett V och aro vanda mot varandra med sina resp. spetsar. Vid denna sjatte utforingsform fir munstycket 15 forsett med tva mot varandra placerade springer 26, som i langdriktningen delar dess inre del i tva. halvor 27 och. 28. Dessa halvor aro normalt skilda fran varandra, sasom visas I fig. 8. Det pa detta satt anordnade munstycket 15 kan infOras i mynningen av den yttre anden av ledningen 6 genom att elastiskt narma de tva halvorna 27 och 28 till varandra, varvid desamma inforas i och fa passera ge- — —3 nom namnda mynning och darefter fa atertaga sitt relativt atsldlda lage, sa att de forhindra munstycket att lamna ledningens mynfling. An extension forming elastic patches similar to the patches 25 in Fig. 6 could likewise be provided by any of the embodiments described above to form a joint which prevents any backflow of liquid between the padding tube 4 and the mouth of the conduit 6. In the fourth and sixth embodiments, shown in Figs. 8, the cradles of the conduit 6 are taken towards each other at two mutually abutting parts, one on each side of the long axis of the conduit, by means of the welds 9. In the case where the conduit 6 is formed by a flattened tube and not by two superimposed discs .salunda welding joints 9 pa. the same was to keep the cradles of the pipe taken towards each other, the edges of the pipe not being welded together in the longitudinal direction. The welds 9 contribute, in conjunction with the arrangement by which the cradles to the conduit 6 separate Iran at the opening of the conduit, to form a fold 16 in each conduit cradle. In the fifth embodiment, shown in Fig. 7, the welds 9 extend perpendicular to the edges of the conduit 6, during part one the welds 9 in the sixth embodiment shown in Fig. 8 each have the shape ay a V and aro weld towards each other with their resp. lace. In this sixth embodiment, the nozzle 15 is provided with two jaws 26 placed against each other, which in the longitudinal direction divide its inner part into two. halves 27 and. 28. These halves are normally separated from each other, as shown in Fig. 8. The nozzle 15 arranged in this way can be inserted into the mouth of the outer spirit of the conduit 6 by elastically approaching the two halves 27 and 28 to each other, the same introduced into and allowed to pass through the said estuary and then allowed to regain their relatively atsldlda layer, so that they prevent the nozzle from leaving the mouth of the conduit.

Air fig. 4 och 5 framgar, att behallaren 1 pa tva. motsatta sidor ãr fOrsedd med gavelstyckena 19, som giva densamnaa en. form, som gOr det mojligt att den hailer sig stdende pa bottnen, sedan den blivit pafylld. Air Figs. 4 and 5 show that the container 1 on two. opposite sides are provided with the end pieces 19, which give the same one. form, which makes it possible for it to stand on the bottom after it has been filled.

For att underlatta markeringen av mynningen till den yttre anden av ledningen 6 kan enligt en variant en del av den anordning, som bestar av munstycket 15 vid utforingsformerna enligt fig. 1, 3, 6, 7 och 8, av de tunna skivorna 20 och 21 vid den. i fig. 4 visade utforingsformen, ()eh av ringen 23 vid utforingsformen enligt fig. 5, vara sjalvlysande. In order to facilitate the marking of the mouth of the outer spirit of the conduit 6, according to a variant a part of the device, which consists of the nozzle 15 in the embodiments according to Figs. 1, 3, 6, 7 and 8, of the thin discs 20 and 21 at it. in Fig. 4 the embodiment, () eh of the ring 23 in the embodiment according to Fig. 5, is shown to be luminescent.

Fig. 9 visar en halvautomatisk maskin for pafyllning av tata forpackningar, exempelvis dylika som visas i fig. 1, 3, 6 och 8. Denna ma-skin bestar av en glidbana 31, som bildas av tva parallella metallband, vilka aro atskilda frau varandra och med vilkas tillhj alp de allm5.nt med beteekningen 1 angivna fOrpaekningarna aro upphangda vid sina munstycken 15. Maskinen ar forsedd med anordningar for att sterilisera forpackningarna fore deras pafyllning. F5r detta andamal forflyttas farpackningarna av tyngdkraften mot ett pafyllningsstalle forsett med en palyllningspip 32 och passera mellan sjalvlysande ror 33, som utsanda ultravioletta stralar. Dessa stralar ga. Mrs genom en kvartsplatta 34, vilken forhindrar forpackningarna 1 att komma i kontakt Hied det sjalvlysande roret 33 och att smalls_ ned vid beroringen. Reflektorerna 35 och 36 sakerstalla en i huvudsak total och likformig bestralning ay forpackningarna 1 me-deist de ultravioletta stralarna: Den symmetriska placeringen av de tva roren 33 med deras skyddsplattor 34 och deras reflektorer 35 liksom laget ay den 8vre reflektorn 36 ar tydligt synlig i fig. 10. Darav framgar, att var och en av reflektorerna 35 Sr pa ett reglerbart salt upphangd vid ett stod 37 med tillhjalp av en skruy 38, som gar genom en avlang oppning 39 i delta st8d och genom ett beslag 40, som ar punktsvetsat vid reflektorn 35, f6r att samverka med den vid beslaget 40 mellan detta och reflektorn 35 fastli5dda muttern 41. Det inses, att roret 33 med dess skyddsplatta 34 kan upphangas vid reflektorn 35 med tillhj alp av en anordning av vilken Wand typ som helst. Fig. 9 shows a semi-automatic machine for filling tata packages, for example those shown in Figs. 1, 3, 6 and 8. This machine consists of a slide 31, which is formed by two parallel metal strips, which are separated from each other and with the aid of which the packages generally indicated by the designation 1 are suspended from their nozzles 15. The machine is provided with devices for sterilizing the packages before their filling. For this purpose, the packages are moved by gravity towards a filling stall provided with a filling pipe 32 and pass between luminescent tubes 33, which emit ultraviolet rays. These rays give. Mrs through a quartz plate 34, which prevents the packages 1 from coming into contact with the luminescent tube 33 and narrowing at the touch. The reflectors 35 and 36 provide a substantially total and uniform irradiation of the packages 1 by means of the ultraviolet rays: The symmetrical placement of the two tubes 33 with their protective plates 34 and their reflectors 35 as well as the layer of the 8th reflector 36 is clearly visible in fig. 10. It follows that each of the reflectors 35 is mounted on an adjustable salt suspended at a stand 37 by means of a screw 38 which passes through an elongate opening 39 in the delta support and through a fitting 40 which is spot welded at the reflector 35, to co-operate with the nut 41. attached to the fitting 40 between the reflector 35 and the reflector 35. It will be appreciated that the tube 33 with its protective plate 34 can be suspended at the reflector 35 by means of a device of any Wand type.

Efter att ha passerat mitt f Sr de sjalvlysande roren 33 uppsamlas forpackningarna nedanfor det ay glidbanan 31 bildade lutande planet, varvid glidbanan darefter bildar en avrundad puekel, som angives med beteckningen 42 i fig. 9. De forpackningar, som samlats mellan namnda lutande plan. och namnda avrundade puekel foras for hand anda mitt framfor pafyllningspipen 32. Under loppet av denna forflyttning later man dem vrida sig 900 omkring munstyckets axel for att fora dem i det ldge, som forpackningen I' intar i fig. 9. I detta lage uppbaras forpackningarna av ett reglerbart stod besthende av en vinkelformad del 43 och tva. fOrlangningar 44 och 45, vilkas resp. lagen aro reglerbara vinkelratt mot det ena, resp. det andra »benet» av delen 43 me-deist knapparna 46. Till hoger om pafyllningspipen 32 är maskinen forsedd med de i fig. 11 visade anordningarna, som tjana till att hall. den pa delen 43 framforda forpackningen ororlig mittf Sr den namnda pafyllningspipen, sa att pipen kan sankas och infOras i munstycket 15 pa. namnda forpackning. Dessa anordningar utgoras av en kniptang 47 med skanklarna 48 ocb. 49, som kunna hoptryeka namnda munstycke. Kniptangen Sr yid 50 ledbart forbunden med en fast del av maskinen och dess skanklar leda mot varandra yid 51. After passing in the middle of the luminescent tubes 33, the packages are collected below the inclined plane formed by the slideway 31, the slideway then forming a rounded hump, indicated by the designation 42 in Fig. 9. The packages collected between said inclined plane. and the said rounded puelel is lined by hand in the middle in front of the filling spout 32. During the course of this movement they are allowed to rotate 900 about the axis of the nozzle to feed them in the space occupied by the package I 'in Fig. 9. In this layer the packages are carried of an adjustable stand consisting of an angular part 43 and two. Extensions 44 and 45, the respective the law aro adjustable angle steering wheel towards one, resp. the second "leg" of the part 43 has the buttons 46. To the right of the filling spout 32, the machine is provided with the devices shown in Fig. 11, which serve to hold. the package advancing on the part 43 unmoving in the middle is the said filling spout, so that the spout can be collected and inserted into the nozzle 15 on. named packaging. These devices are constituted by a pair of pliers 47 with the shanks 48 ocb. 49, which can compress the said nozzle. The clamping pliers Sr yid 50 are hingedly connected to a fixed part of the machine and its shanks lead towards each other yid 51.

Pa fig. 9 kan man se en sjunde utfOringsform av forpackningen. Denna utforingsform bestar ay en platt behallare ay rektangular form med en oppning, som Sr forsedd med en automatisk stangningsventil 6. Denna ventil bestar av tva folier av ett termoplastiskt amne, t. ex. polyetylen, som bilda en platt led-fling och som vardera bestar av tva mitt for varandra belagna och standigt mot motsvarande del av den andra folien anbragta delar. Dessa delar aro forbundna med varandra me-deist svets- eller lodfogar 9. Den mellan desamma Astadkomna ledningen blir ant trangre riktning mot det inre av behallaren. Ventilen 6 Sr fastrodd i den Oppning, som bildas vid behallarens ovre kant. Lodfogarna 5 yid denna ovre kant tinsluta likaledes ventilen till en del, i det de bilda en atstrypning av denna pa det stalle ddr densamma Sr forbunden med beh&llarens vaggar. Munstyeket 15 ar nedpressat i den iippning, som fortfarande finnes mellan namnda lodfogar 5. Munstycket har en yttre del 29 med stone diameter, i vilken är anordnad en eirkelformad ranna 30. Den yttre delen av munstycket 15 Sr en rotationskropp, liksom munstyckets mynning, sa att de forpackningar, som medelst sina munstyeken 15 aro upphangda vid glidbanan 31 kunna efter behag installas i alla riktningar. Vid denna sjunde utforingsform är for ovrigt hela munstycket en rotationskropp, vilket hailer ledningsvaggarna i -ventilen 6 atskilda frau varandra pa en del av ledningen och astadkommer bildandet pa atminstone en av namnda vaggar ay ett veek 16 som soker att hdlla ventilen 6 tillsluten vid dess inre ande oberoende av trycket av den i behallaren befintliga vatskan. Det är tydligt att munstycket 15 underlattar inforandet i ledningen till ventilen 6 av ett ror, som man infOr tvars genom denna ventil, anda fill det inre av behallaren, i syfte att i forvag infora en del av dennas innehall genom detta ror. Sasom framgar av fig. 9, underlattar salunda munstycket 15 dessutom pafyllningen av forpackningen darigenom, att det vander ett koniskt sate mot anden av pa- 4— 17-570 — fyllningspipen 32 och med denna salunda bildar en tat fog for valskan. Fig. 9 shows a seventh embodiment of the package. This embodiment consists of a flat container of rectangular shape with an opening, which is provided with an automatic shut-off valve 6. This valve consists of two foils of a thermoplastic blank, e.g. polyethylene, which form a flat articulated flake and which each consists of two parts which are located opposite each other and permanently arranged against the corresponding part of the second foil. These parts are connected to each other by means of welding or solder joints 9. The line provided between them is narrowly directed towards the interior of the container. Valve 6 Be secured in the opening formed at the upper edge of the container. The solder joints 5 at this upper edge likewise close the valve to a part, in that they form a throttle of this on the spot where the same is connected to the cradles of the container. The nozzle 15 is pressed into the opening which still exists between said solder joints 5. The nozzle has an outer part 29 with stone diameter, in which a circular tube 30 is arranged. The outer part of the nozzle 15 is a rotating body, that the packages, which by means of their nozzles 15 are suspended at the slideway 31, can be installed in all directions at will. In this seventh embodiment, moreover, the entire nozzle is a rotating body, which holds the conduit cradles in the valve 6 separated from each other on a part of the conduit and causes the formation of at least one of said cradles in a wick 16 which seeks to keep the valve 6 closed at its interior independent of the pressure of the liquid contained in the container. It is clear that the nozzle 15 facilitates the insertion into the line to the valve 6 of a tube, which is inserted transversely through this valve, inhaling the interior of the container, in order to pre-insert a part of its contents through this tube. As can be seen from Fig. 9, the salunda nozzle 15 also facilitates the filling of the package in that it travels a conical sate against the spirit of the filling pipe 32 and with this salunda forms a tat joint for the roller.

Den i fig. 12 visade varianten skiljer sig fran den sjunde utforingsformen darigenom, att munstycket 15 just under lodfogarna 5 her en. ringformig ansats 24, som hailer munstycket annu bathe fast i mynningen till ledningens ventil 6. Lodfogarna vid denna ventil dro visade parallellt med varandra, vilket gores majligt genom bildandet av vecket 16, vilket avsevdrt fOrbattrar tatheten av en sadan ventil. The variant shown in Fig. 12 differs from the seventh embodiment in that the nozzle 15 is just below the solder joints 5 here. annular shoulder 24, which holds the nozzle annu bathe fixed in the mouth of the line valve 6. The solder joints at this valve drew parallel to each other, which is made possible by the formation of the fold 16, which considerably improves the tightness of such a valve.

Den i fig. 13 visade varianten skiljer sig fran den enligt fig. 12 darigenom att munstycket 15 i stallet for rannan 30 endast ãr for-sett med en ovre flans 29. The variant shown in Fig. 13 differs from that according to Fig. 12 in that the nozzle 15 in the stable of the gutter 30 is only provided with an upper flange 29.

Den i fig. 14 och 15 visade varianten utgores av ett profilerat munstycke, som i sektion har tva diametralt motsatta spetsar. Detta mun stycke är fastlott vid behallaren mellan de ovre kanterna av ventilen 6 samtidigt med att man utfor lodfogarna 5. Tva tvargaende ran-nor Oro forsedda med tvá at sidan utgaende spetsar 29', som tjana till att uppbara forpackningen pa en glidbana sasom den vid 31 visade. For det fall att man skulle vrida forpackningen i forhallande till denna glidbana och omkring axeln till munstycket 15, skulle spetsarna 29' frigoras fran glidbanan och forpackningen skulle da falla fritt. Detta arrangemang ken vara fordelaktigt i vissa fall. Det dr joke lampligt for pafyllning av forpackfinger medelst den i fig. 9, 10 och 11 visade maskinen. The variant shown in Figs. 14 and 15 consists of a profiled nozzle, which in section has two diametrically opposite tips. This nozzle is fixed to the container between the upper edges of the valve 6 at the same time as the plumb joints 5. Two transverse ridges are provided with two side-extending tips 29 ', which serve to support the package on a slide such as that at 31 showed. In the event that the package were to be rotated in relation to this slide and around the shaft of the nozzle 15, the tips 29 'would be released from the slide and the package would then fall freely. This arrangement can be advantageous in some cases. It is suitable for filling the forefinger by means of the machine shown in Figs. 9, 10 and 11.

Fig. 16 och 17 visa ytterligare tva fOrpackningsvarianter. Varianten enligt fig. 16 ar analog med den enligt fig. 13, frail vilken den skiljer sig ddrigenom, att munstycket 15 icke ar farsett med flansen 24. Varianten enligt fig. 17 ar analog med den i fig. 12, fran vilken den skiljer sig darigenom, att rannan 30 dr ersatt med tvA diametralt mot varandra be- . lagna och i ett enda stycke med namnda mun- stycke gjutna utbuktningar 30'. Det inses alt den yttre ytan av ett munstycke 15 i form av en tratt sasom vid utforingsformerna enligt fig. 1--3, 6 oth 8 kan likaledes samverka med, en glidbana sasom den i maskinen enligt fig. 9-11, samt tjana till att upphanga forpackningen vid denna glidbana. Figs. 16 and 17 show two further packaging variants. The variant of Fig. 16 is analogous to that of Fig. 13, from which it differs in that the nozzle 15 is not fitted with the flange 24. The variant of Fig. 17 is analogous to that of Fig. 12, from which it differs. thereby, that the groove 30 dr replaced with tvA diametrically opposite each other be-. bent and in a single piece with said nozzle cast bulges 30 '. It will be appreciated that the outer surface of a nozzle 15 in the form of a funnel as in the embodiments of Figs. 1--3, 6 and 8 may likewise cooperate with, a slide such as that in the machine of Figs. 9-11, and serve to to hang the packaging at this slide.
