Description
Opfindelsen angår et lukke til fleksible beholdere af et slange- eller sækformet emne til transport og oplagring af flydende gods eller styrtgods, hvilket lukke udgøres af et klemmeorgan, der består af flere stænger, der kan fikseres i forhold til hinanden, samt af et med mindst yderligere en stang forsynet sikringselement, der til sikring af beholderens ved opvikling på en opvikiingsstang lukkede mundingsparti mod afrulning fra denne opvikiingsstang er anbragt ved omkredsen af denne.BACKGROUND OF THE INVENTION The invention relates to a closure for flexible containers of a hose or bag-shaped article for transporting and storing liquid or bulk goods, which closure comprises a clamping means consisting of several rods which can be fixed relative to each other, and of at least one a further rod provided with a locking element which is secured at the circumference thereof to secure the mouth portion of the container closed by unwinding on a winding rod against unrolling from this winding rod.
Sådanne beholdere har et rumfang pi f.eks. 1000 i eller 2000 I og anvendes fortrinsvis i katastrofetilfælde, hvor de f.eks. tjener til forsyning af befolkningen med drikkevand. De egner sig dog f.eks. også til oplagring af drikkevand eller spildevand på skibe eller til oplagring af andre væsker. Transporten af beholderne sker sædvanligvis med lastvogne, hvis tilladte totalvægt ikke må overskrides. Det kan derfor ved anvendelse af mindre lastautomobiler være nødvendigt ikke at fylde beholderen helt. I dette tilfælde kan væskens dynamiske massekræfter under kørslen imidlertid medføre fare for køretøjet, og der kræves derfor et lukke, med hvilket det rumfang af beholderen, som ikke udfyldes, kan formindskes eller helt elimineres.Such containers have a volume pi e.g. 1000 i or 2000 i and preferably used in emergency cases where they e.g. serves to supply the population with drinking water. However, they are suitable for example. also for the storage of drinking water or wastewater on ships or for the storage of other liquids. The transport of the containers is usually carried by trucks, the maximum permissible weight of which must not be exceeded. Therefore, when using smaller trucks, it may not be necessary to fill the container completely. In this case, however, the dynamic mass forces of the liquid while driving may pose a danger to the vehicle, and therefore a closure is required, with which the volume of the container which is not filled can be reduced or completely eliminated.
Det er endvidere netop af hensyn til en hurtig anvendelse i katastrofetilfælde nødvendigt, at lukket er så enkelt som muligt at betjene. I mange tilfælde kan en så pladsbesparende udformning af lukket som muligt være nødvendig for f.eks. at muliggøre stabling af flere beholdere ovenpå hinanden.Furthermore, it is precisely for the sake of rapid use in emergency cases that the closure is as simple as possible to operate. In many cases, a space-saving design of the closure as possible may be necessary for e.g. to allow stacking of several containers on top of each other.
Et til disse formål egnet lukke af den indledningsvis nævnte art kendes f.eks. fra tysk offentliggørelsesskrift nr. 3.004.884. Det fra dette offentliggørelsesskrift kendte lukke består af oven over hinanden anbragte klemmeorganer, der ved enderne fastholdes i holdere på en sådan måde, at en ende af det slange- eller sækformede emne kan føres gennem mellemrum mellem klemmeorganerne. Klemme-organerne er anbragte forskydeligt i retning mod hinanden og indrettet til at kunne spændes mod hinanden ved hjælp af spændeorga-ner, der kan indsættes i hver sin holder.A closure of this kind suitable for these purposes is known e.g. from German Publication No. 3,004,884. The closure known from this publication consists of superposed clamping means which are held at the ends in holders in such a way that an end of the tubular or bag-shaped blank can be passed through spaces between the clamping means. The clamping means are arranged in a displaceable direction towards each other and arranged to be able to be clamped against each other by means of clamping means which can be inserted into each holder.
En ulempe ved dette kendte lukke er, at det består af forholdsvis mange enkeltdele, hvilket vanskeliggør betjeningen og forøger muligheden for svigtende funktion. Endvidere er dette lukke af forholdsvis store dimensioner og gør stabling af flere beholdere oven på hinanden vanskelig. Dette kendte lukkes store dimensioner er især en ulempe ved beholdere med et mindre rumfang.A disadvantage of this known closure is that it consists of relatively many individual parts, which makes operation difficult and increases the possibility of malfunctioning. Furthermore, this closure is of relatively large dimensions and makes stacking of several containers on top of each other difficult. The large dimensions of this known closure are especially a disadvantage of containers with a smaller volume.
Et lukke af den omhandlede art kendes også fra den franske patentbeskrivelse nr. 1.458.178. Dette lukke har en opviklings-stang, på hvilken beholderåbningsafsnittet af beholderen, der skal lukkes, opvikles. Efter opviklingen af dette afsnit på opviklingsstangen anbringes et klemmeelement langs siden. For at forhindre at det på opviklingsstangen opviklede beholderåbningsafsnit atter afrulles af opvikiingsstangen, er en afrulningssikring i form af et klemmeorgan skudt ind på opviklingsstangen.A closure of the kind in question is also known from French Patent Specification No. 1,458,178. This closure has a winding rod on which the container opening portion of the container to be closed is wound. After the winding of this section on the winding rod, a clamping element is placed along the side. In order to prevent the container opening section wound on the winding rod from being unwound again by the winding rod, a reeling lock in the form of a clamping means is inserted into the winding rod.
Et lignende lukke kendes fra den franske patentbeskrivelse nr. 78.061. Dette kendte lukke har ligeledes den ulempe, at det består af forholdsvis mange enkeltdele, der vanskeliggør betjeningen og forøger faren for svigtende funktion. Det er endvidere en væsentlig ulempe, at det er vanskeligt og besværligt at vikle beholderåbningsafsnittet op på opviklingsstangen, og at det her navnlig skal påses, at åbningsafsnittet ikke vikles skævt op på opviklingsstangen. Dertil kommer, at dette kendte lukke ikke yder absolut sikkerhed mod utætheder efter åbningsafsnittets opvi kling på opviklingsstangen, således at der især ved et højt indvendigt tryk i beholderen kan optræde utætheder. Endelig er heller ikke de allerede beskrevne ulemper med hensyn til håndteringen af lukket og dets pladsbehov elimineret ved dette kendte lukke.A similar closure is known from French Patent Specification No. 78,061. This known closure also has the disadvantage that it consists of relatively many individual parts which make operation difficult and increase the risk of malfunction. Furthermore, it is a major disadvantage that it is difficult and cumbersome to wrap the container opening section up on the winding rod, and in this case it must be particularly observed that the opening section is not skewed upwards on the winding rod. In addition, this known closure does not provide absolute security against leaks after the opening of the opening section on the winding rod, so that leaks can occur especially at high internal pressure in the container. Finally, the disadvantages already described with regard to the handling of the closure and its space requirements have not been eliminated by this known closure.
Formålet med opfindelsen er derfor at tilvejebringe et lukke af den indledningsvis nævnte art, ved hvilken opviklingen af beholderens åbningsafsnit på opviklingsstangen er lettet, og som selv ved et højt indre tryk i beholderen sikrer eri fuldstændig tæthed af den dermed lukkede beholderåbning og endvidere har mindre dimensioner end de nævnte kendte lukker.The object of the invention is therefore to provide a closure of the kind mentioned above, in which the winding of the opening portion of the container on the winding rod is facilitated and which even at high internal pressure in the container ensures complete tightness of the closed container opening and furthermore has smaller dimensions. than the known closures mentioned.
Denne opgave løses ifølge opfindelsen ved, at opviklingsstangen er udformet med en slids, der er indrettet til optagelse af deri indførte dele af en overdel og en underdel af beholderen, der med mindst to ombøjninger rundt om opviklingsstangens af slidsen dannede kanter er rullet stramt og uden folder mindst 270° om opviklingsstangen.This task is solved according to the invention in that the winding rod is formed with a slot adapted to receive parts of an upper part and a lower part of the container which, with at least two bends around the edges of the winding rod of the slot, are tightly tightened and without folds at least 270 ° about the winding rod.
Fordelen ved dette lukke er, at opviklingen på opviklingsstangen af behoideråbningsafsnittet af beholderen, der skal lukkes, lettes ved hjælp af slidsen i opviklingsstangen. Ved opviklingen skal behoideråbningsafsnittet blot indskydes i slidsen, hvorefter der allerede ved en drejning på 90° af opviklingsstangen ikke længere kan ske en glidning af beholderåbningsafsnittet pi opviklingsstangen. Dersom kun et mindre volumen af beholderen er nødvendigt, gør slidsen det særligt nemt at vikle beholderåbningsafsnittet flere gange om opviklingsstangen. En yderligere fordel er, at der ved hjælp af slidsen dannes en klemmekant, der selv ved et højt indre tryk i beholderen tætter denne effektivt. Det er yderligere en fordel, at lukket kun består af få dele og dermed har en større funktions-sikkerhed. Endvidere har lukket en væsentligt mindre vægt end de kendte lukker.The advantage of this closure is that the winding on the winding rod of the container opening section of the container to be closed is facilitated by the slot in the winding rod. During winding, the container opening section must only be inserted into the slot, after which, at a rotation of 90 ° of the winding rod, no longer can a sliding of the container opening section of the winding rod. If only a small volume of the container is needed, the slot makes it particularly easy to wrap the container opening section several times around the winding rod. A further advantage is that by means of the slot a clamping edge is formed which even at a high internal pressure in the container seals it effectively. It is a further advantage that the closure consists of only a few parts and thus has a greater functional security. Furthermore, the closure has a substantially smaller weight than the known closures.
Ifølge opfindelsen kan af rulningssikringselementet hensigtsmæssigt udgøres af et spændeelement i form af en med opviklingsstangen parallel stang, der ligger an mod den opviklede over- og underdel af beholderen og ved hjælp af spændeskruer er forbundet med opviklingsstangen.According to the invention, the rolling securing element may conveniently be constituted by a clamping element in the form of a rod parallel to the winding rod which abuts the wound upper and lower part of the container and by means of clamping screws connected to the winding rod.
Spændeelementet kan ifølge opfindelsen være udformet som en skinne med U-formet profil til delvis eller fuldstændig optagelse af opviklingsstangen. Denne udførelsesform har den fordel, at over- og underdelen af den fleksible beholder, der skal lukkes, klemmes mod den med slidsen forsynede stang ved to kanter af det U-formede profil, hvorved det opnås, at lukket er ekstra tæt.In accordance with the invention, the clamping member can be formed as a rail with a U-shaped profile for partial or complete uptake of the winding rod. This embodiment has the advantage that the upper and lower parts of the flexible container to be closed are clamped against the slotted bar at two edges of the U-shaped profile, thereby obtaining that the closure is extra tight.
Ifølge en anden udførelsesform for lukket ifølge opfindelsen kan afrulningssikringselementet bestå af to med opviklingsstangen parallelle firkantrør eller profilstænger, der fra hver sin side af opviklingsstangen ligger an mod den derpå opviklede over- og underdel af beholderen og mellem hver ende af slidsen og hver ende af opviklingsstangen er forbundne med hinanden ved hjælp af spændeskruer, der strækker sig gennem opviklingsstangen.According to another embodiment of the closure according to the invention, the unrolling securing element may consist of two square tubes or profile bars parallel to the winding rod which abut from the side of the winding rod against the upper and lower part of the container and between each end of the slot and each end of the winding rod. are connected to each other by means of tensioning screws extending through the winding rod.
Ifølge yderligere en udførelsesform for lukket ifølge opfindelsen kan afrulningssikringselementet udgøres af et hylster, der kan skydes således ind på opviklingsstangen, at den kan gribe fast om det opviklede beholderåbningsafsnit og i påskudt stilling være fikseret udrejeligt i forhold til opviklingsstangen. Ved udformningen af afrulningssikringselementet som et hylster, opnås en hurtig og pålidelig fiksering af det på opviklingsstangen opviklede beholderåbningsafsnit. Ekstra elementer, såsom spændeskruer, der kan bortkomme, når lukket er åbent og under rensningen af beholderen, er ikke nødvendige. Hylsteret kan skydes ind på opviklingsstangen i aksial retning af denne. Da hylsteret i påskudt stilling er fikseret udrejeligt, kan det oprullede beholderåbningsafsnit ikke løsnes af sig selv, og behol- deren er således lukket pålideligt. Betjeningen af lukket er yderligere lettet, og funktionssikkerheden forøget.According to a further embodiment of the closure according to the invention, the unrolling securing element may be constituted by a sleeve which can be slid into the winding rod so that it can grasp the wound container opening section and in the preloaded position can be removably fixed relative to the winding rod. In designing the roll-off securing element as a sleeve, a fast and reliable fixation of the container opening portion wound on the winding rod is obtained. Additional elements, such as clamping screws that can be removed when the closure is open and during the cleaning of the container, are not necessary. The sleeve can be slid onto the winding rod in the axial direction thereof. As the casing in the preloaded position is removably fixed, the rolled-up container opening portion cannot be loosened by itself, and thus the container is reliably closed. The operation of the closure is further facilitated and functional safety increased.
Ifølge opfindelsen kan hylsteret fordelagtigt fastholdes udrejeligt på opviklingsstangen ved, at både hylsteret og opviklings-stangen har et fra et cirkulært tværsnitsprofil afvigende tværsnitsprofil. Hertil kan hylsterets og opviklingsstangens tværsnitsprofil være firkantet, fortrinsvis kvadratisk, eller ovalt. Ved denne særlige udformning af tværsnitsprofilet kan særlige organer til sikring af hylsteret og opviklingsstangen mod indbyrdes drejning udelades.According to the invention, the casing can advantageously be held retractably on the winding rod in that both the casing and the winding rod have a cross sectional profile which differs from a circular cross-sectional profile. For this, the cross-sectional profile of the sheath and the winding rod may be square, preferably square, or oval. In this particular design of the cross-sectional profile, special means for securing the casing and winding rod against mutual rotation can be omitted.
Ifølge en anden udførelsesform for lukket ifølge opfindelsen har hylsteret og opviklingsstangen med begge dele indgribende organer til sikring af delene mod drejning i forhold til hinanden. Hertil kan hylsterets ende være forsynet med en indkærvning, i hvilken en ved den pågældende ende af opviklingsstangen anbragt og i radial retning forløbende tap indgriber. Denne udførelsesform giver også mulighed for at anvende en opviklingsstang og et hylster med rundt tværsnit. I en foretrukken videreudformning har hylsteret en i længderetningen gennemgående længdeslids, i hvilken en som sikringsorgan til sikring mod indbyrdes drejning mellem hylsteret og opviklingsstangen tjenende, ved enden af opviklingsstangen anbragt tap, der strækker sig i radial retning, indgriber efter påskydningen af hylsteret. Det er her særligt fordelagtigt, dersom ifølge yderligere en videreudformning, hver ende af længdeslidsen tjener til optagelse af en ved den tilsvarende ende af opviklingsstangen anbragt tap. Herved opnås, foruden at hylsteret ikke skal udformes med en ekstra indkærvning, at længdeslidsen sammen med tappene til føring af hylsteret ved dettes påskydning på opviklingsstangen. Derved undgås at hylsteret drejer sig i forhold til opviklingsstangen under påskydningen.According to another embodiment of the closure according to the invention, the sheath and the winding bar with both parts have engaging means for securing the parts against rotation with respect to each other. To this end, the end of the sheath may be provided with a notch in which a pin located at the relevant end of the winding rod engages in a radial direction. This embodiment also allows the use of a winding rod and a sleeve of round cross section. In a preferred further embodiment, the sheath has a longitudinal longitudinal slot in which a pin extending in radial direction, which serves as a securing means for securing mutual rotation between the sheath and the winding rod, engages the end of the winding rod. It is particularly advantageous here, if according to a further embodiment, each end of the longitudinal slot serves to receive a pin located at the corresponding end of the winding rod. In this way, in addition to the casing not having to be designed with an extra notch, the longitudinal slot together with the pins for guiding the casing is obtained by its pushing on the winding rod. This prevents the casing from rotating with respect to the winding rod during the push-up.
Ifølge yderligere en ejendommelighed ved, lukket ifølge opfindelsen består hylsteret af et elastisk materiale og er i friktionsindgreb med ydersiden af det opviklede beholderåbningsafsnit. Fortrinsvis har længdeslidsen en bredde, som er mindre end tykkelsen af det sammen klappede beholderåbningsafsnit, således at længdekanterne af hylsterets længdeslids efter hylsterets påskydning ligger an mod ydersiderne af det sammen klappede beholderåbningsafsnit. Herved formindskes faren for utilsigtet forskydning af det påskudte hylster i forhold til opviklingsstangen.According to a further characteristic of, closed according to the invention, the sheath consists of an elastic material and is in frictional engagement with the outside of the wound container opening section. Preferably, the longitudinal slot has a width which is less than the thickness of the collapsed container opening portion so that the longitudinal edges of the longitudinal slot of the casing abut the outer sides of the collapsed container opening portion. This reduces the risk of accidental displacement of the sheathed casing relative to the winding rod.
Ifølge yderligere en ejendommelighed ved lukket ifølge opfindelsen er den åbning af hylsteret, der ligger modsat den ved den ene ende beliggende indføringsibning, lukket ved hjælp af en plade. Denne plade tjener som anslag og sikrer pi enkel måde den korrekte anbringelse af hylsteret ved dettes påskydning i aksial retning på opviklingsstangen.According to a further feature of the closure according to the invention, the opening of the casing opposite to the insertion opening located at one end is closed by means of a plate. This plate serves as a stop and in a simple way ensures the correct positioning of the casing upon its pushing in axial direction on the winding rod.
Ifølge en videreudformning af lukket ifølge opfindelsen kan dette have to på hver sin ende af opviklingsstangen påskydelige hylstre, der hver har en længde, som er mindre end den halve længde af opviklingsstangen. Derved forenkles fikseringen af det på opviklingsstangen oprullede beholderåbningsafsnit, idet der ikke skal påskydes et til hele længden af opviklingsstangen svarende hylster, men kun to små hylstre, der skydes ind på hver sin ende af opviklingsstangen. Dette er navnlig en fordel ved brede beholderåbninger, hvor der på grund af hylsterets længde optræder en stor friktionsmodstand ved dettes påskydning.According to a further embodiment of the closure according to the invention, this may have two casings slidable at each end of the winding rod, each having a length less than half the length of the winding rod. Thereby, the fixing of the container opening portion wound on the winding rod is simplified, in that a casing corresponding to the entire length of the winding rod is not to be pushed, but only two small casings which are pushed into each end of the winding rod. This is particularly advantageous for wide container openings where, due to the length of the casing, a large frictional resistance occurs upon its pushing.
Ifølge yderligere en udførelsesform for lukket ifølge opfindelsen har hylsteret et U-formet tværsnitsprofil og kan påskydes på tværs af opviklingsstangens aksiale retning og har ved hver ende som glidesikring anbragte midler, der forhindrer glidning af hylsteret modsat dets påskydningsretning. Glidesikringen kan være en på hylsteret påhængslet, drejelig rigel, der griber bag om opviklingsstangen .According to a further embodiment of the closure according to the invention, the sheath has a U-shaped cross-sectional profile and can be pushed across the axial direction of the winding rod and has at each end provided sliding means preventing sliding of the sheath opposite to its shear direction. The anti-slip device can be a swivel, swivel bolt attached to the sheath which grips behind the winding rod.
Glidesikringen kan også være en ring, der kan skydes ind på enden af hylsteret. Det U-formede hylster anvendes til lukning af brede beholderåbninger, hvor der ved en aksial påskydning af hylsteret ville optræde en meget stor friktionsmodstand.The anti-slip device may also be a ring that can be inserted into the end of the case. The U-shaped casing is used for closing wide container openings where a very large frictional resistance would occur upon axial pushing of the casing.

Den i fig. 1 og 2 viste sækformede fleksible beholder 1 består af en overdel 2 og en underdel 3, der f.eks. ved klæbning eller svejsning er forbundne med hinanden ved deres to længdesider og ved den ene ende. Overdelen 2 er forsynet med en påfyldningsåbning 4. Den anden ende af beholderen 1, der indmunder i en hals 6, tjener som beholderåbning 7. Beholderåbningen 7 er lukket ved hjælp af et lukke 8.The FIG. 1 and 2, the bag-shaped flexible container 1 consists of an upper part 2 and a lower part 3 which e.g. by adhesive or welding are connected to each other at their two longitudinal sides and at one end. The upper part 2 is provided with a filling opening 4. The other end of the container 1, which opens into a neck 6, serves as the container opening 7. The container opening 7 is closed by means of a closure 8.
Ved lukning af beholderen 1 føres halsen 6 gennem opvik-lingsstangen 10, der i midten er forsynet med en slids 9, hvorefter halsen ved drejning af opviklingsstangen 10 i retningen ind mod beholderens midte ved den i fig. 3 viste udførelsesform rulles så stramt og uden folder som muligt mindst 360° op på opviklingsstangen. Ved yderligere drejning af opviklingsstangen kan beholderåbningen 7's lag også bringes til at overlappe hinanden. Herunder vil halsen 6, således som det ses i fig. 3, blive ombøjet ved flere steder. Når halsen på ønsket måde er rullet op på opviklingsstangen, kan den oprullede hals fikseres ved spænding af spændeskruerne 13, der er anbragte nær enderne af opviklingsstangen 10. Spændeskruerne 13 er ført gennem et spændeelement 12 med U-formet tværsnitsprofil samt gennem opviklingsstangen 10 og spændes f.eks. ved hjælp af en møtrik.Upon closing of the container 1, the neck 6 is passed through the winding rod 10, which is provided in the middle with a slot 9, after which the neck, when turning the winding rod 10 in the direction towards the middle of the container at the position shown in FIG. 3 is rolled as tightly and without folds as possible at least 360 ° onto the winding rod. By further turning the winding rod, the layers of the container opening 7 can also be made to overlap. Below, the neck 6, as seen in FIG. 3, be bent at several places. When the neck is rolled up on the winding rod as desired, the rolled neck can be fixed by tightening the tensioning screws 13 which are placed near the ends of the winding rod 10. The tensioning screws 13 are passed through a clamping member 12 with a U-shaped cross sectional profile and through the winding rod 10 and tensioned. eg. using a nut.
Ved den ί fig. 4 viste udførelsesform for lukket ifølge opfindelsen rulles beholderåbningen mindst 270° op på opviklingsstangen. Fikseringselementet har her form af to firkantrør 14, der er forbundne ved hjælp af spændeskruer 15, der er ført gennem opviklingsstangen 10 uden for slidsen 9.In the FIG. 4, the container opening is rolled up at least 270 ° onto the winding rod. Here, the fixing element is in the form of two square tubes 14 which are connected by means of clamping screws 15 which are passed through the winding rod 10 outside the slot 9.
Fig. 5-9 viser yderligere udførelsesformer ffor lukket 8, der navnlig adskiller sig fra hinanden ved fikseringselenrientet. Den tomme beholder Vs sammen klappede beholderibning 7 skydes også her ind i slidsen 9 i opviklingsstangen 10, således at kanten saf beholderåbningen 7 kommer til at ligge inden for opviklingsstangen 10. Til fiksering af den på opviklingsstangen 10 oprullede behølderåbning 7 skydes ved udførelsesførmerne ifølge fig. 5-9 et hylster 9 med en længdeslids 21 i aksial retning ind på opviklingsstangen '10 og griber fast om den opviklede beholderåbning 7. Dette hylster T6*s længdeslids 21 kommer herunder till at ligge an med sine to længdékanter mod beholderen Vs overdel 2 og underdel 3. I fig. 5 har både opviklingsstangen 10 og hylsteret 16 et firkantet tværsnitsprofil, således at begge dele fikseres udrejeligt i forhold til hinanden. Pa denne måde er beholderåbningen 7 lukket, idet det påskudte hylster 16 sikrer, at beholderåbningen 7 ikke længere kan løsnes fra opviklingsstangen 10.FIG. 5-9 show further embodiments of the closure 8, which differ in particular from each other by the fixation element. The empty container Vs collapsed container rib 7 is also slid here into the slot 9 in the winding rod 10, so that the edge of the container opening 7 lies within the winding rod 10. For fixing the container opening 7 wound on the winding rod 10, the sliders in FIG. 5-9 a sleeve 9 with a longitudinal slot 21 in axial direction on the winding rod '10 and grips the wound container opening 7. This sleeve T6 *'s longitudinal slot 21 will touch with its two longitudinal edges against the upper part 2 of the container V and sub-section 3. In fig. 5, both the winding rod 10 and the casing 16 have a square cross-sectional profile so that both parts are removably fixed relative to each other. In this way, the container opening 7 is closed, with the slotted casing 16 ensuring that the container opening 7 can no longer be detached from the winding rod 10.
Ved den i fig. 6 viste udførelsesform er tværsnitsprofilet af både opviklingsstangen 10 og hylsteret 16 trekantet. Også her er de to dele fikserede udrejeligt i forhold til hinanden.In the embodiment shown in FIG. 6, the cross-sectional profile of both the winding rod 10 and the casing 16 is triangular. Here, too, the two parts are fixed removable in relation to each other.
Ved den i fig. 7a viste udførelsesform for lukket 8 har opviklingsstangen 10 og hylsteret 16 et rundt tværsnitsprcfil, således at der ved denne udførelsesform skal anvendes en ekstra drejningssikring. Denne er vist i fig. 7b. Enden af hylsteret 16 er forsynet med en indkærvning 20, i hvilken der efter hylsteræt 16‘s påskydning indgriber en som drejningssikring tjenende tap 19„ der er anbragt ved den pågældende ende af opviklingsstangen 10 ©g strækker sig i radial retning. Her kan også selve længdeslidsen 2Λ i hylsteret 16 tjene som indkærvning 20. I dette tilfælde tjener længdeslidsen 21 desuden som føring ved påskydningen af hylsteret 1¾.In the embodiment shown in FIG. 7a of the closed 8 embodiment, the winding rod 10 and the casing 16 have a circular cross sectional profile, so that in this embodiment an extra pivot lock must be used. This is shown in FIG. 7b. The end of the casing 16 is provided with a notch 20, in which, after the casing of the casing 16, a pin 19 "serving as a torque retaining device", which is located at the relevant end of the winding rod 10 g, extends in the radial direction. Here, too, the longitudinal slot 2Λ of the casing 16 can serve as notch 20. In this case, the longitudinal slot 21 also serves as a guide when pushing the casing 1¾.
Ved den i fig. 8 og 9 viste udførelsesform for lukket 8 har hylsteret 16 et U-formet tværsnitsprofil og piskydes pi tværs af opviklingsstangen 10ls aksiale retning, d.v.s. fra højre på tegningen. For at forhindre at hylsteret 16 glider på den på opviklingsstangen 10 oprullede beholderåbning 7, er der anbragt en ekstra forskydningssikring. Hertil er der i fig. 8b på hylsteret 16 anbragt en drejelig rigel 17, der før og under hylsteret 16's påskydnimg på opviklingsstangen 10 befinder sig i den med stiplede linier viste stilling. Efter påskydningen drejes rigelen 17 nedad og forhindrer derved, at hyl steret 16 løsner sig· En anden mulighed er vist i fig. 9a og 9b, hvor der på hver ende af hylsteret 16 er påskudt en bøjleformet ring 18.In the embodiment shown in FIG. 8 and 9, the casing 16 has a U-shaped cross-sectional profile and is whisked across the axial direction of the winding rod 10l, i.e. from the right of the drawing. In order to prevent the casing 16 from sliding on the container opening 7 wound on the winding rod 10, an additional shear protection is provided. For this, in FIG. 8b of the casing 16 is arranged a pivotal bolt 17 which, before and during the casing 16 of the casing 16 on the winding rod 10, is in the position shown in broken lines. After pushing, the bolt 17 is turned downwards, thereby preventing the sleeve 16 from loosening. Another possibility is shown in fig. 9a and 9b, wherein on each end of the casing 16 a hoop-shaped ring 18 is fitted.
I de . viste udførelseseksempler er beholderen 1 sækformet, således at der kun kræves et lukke 8. Det er dog også muligt som beholder 1 at anvende et ved begge ender åbent slangeformet emne, i hvilket tilfælde der da kræves to lukker 8. Derved kan beholderen 1's rumfang formindskes fra begge sider til et bestemt rumfang.In the. In the illustrated embodiments, the container 1 is bag-shaped so that only one closure is required 8. However, it is also possible as container 1 to use a hose-shaped workpiece open at both ends, in which case two closures 8 are required. Thus, the volume of the container 1 can be reduced. from both sides to a specific volume.
