Opfindelsen angår en bund til en transport- eller væskecontainer, og af den i krav l's indledning angivne art.The invention relates to a bottom for a transport or liquid container, and of the kind specified in the preamble of claim 1.
Væskecontainere er velkendte og omfatter en beklædt ramme 5 med vægge, hvorved der dannes en lukket container eller kasseformet beholder. Containeren indeholder en pose med fluidet, der skal transporteres. Et eksempel herpå er givet i dansk offentliggørelsesskrift nr. 1787/86. Posen anbringes inden påfyldning i containeren. Posen vil for-10 trinsvis være fleksibel og besidde en ikke uvæsentlig brudstyrke, og den kan f.eks. være fremstillet af et flerlaget plastmateriale, såsom polyethylen. Posen bibringer tætheden, mens containerrammen bibringer den fornødne stabilitet. Containerne kan derfor udformes ret 3 15 store og typisk have et nyttevolumen på mere end 1 m . Håndteringen af containerne sker ved brug af gaffeltruck.Liquid containers are well known and comprise a sheathed frame 5 with walls, forming a closed container or box-shaped container. The container contains a bag of the fluid to be transported. An example of this is given in Danish publication no. 1787/86. Place the bag before filling in the container. The bag will preferably be flexible and possess a not insignificant breaking strength, and it may e.g. be made of a multilayer plastic material such as polyethylene. The bag provides tightness while the container frame provides the necessary stability. The containers can therefore be designed quite large and typically have a useful volume of more than 1 m. The containers are handled using a forklift truck.
Der er tale om en meget attraktiv måde at håndtere fluider på, idet der ikke kun er tale om væsker, men også granulater og andet kornmateriale, da transportvolumenet 20 har en høj udnyttelsesgrad i modsætning til andre former for beholdere, såsom tønder og tanke. Samtidigt er containerne sammenklappelige, hvorved pladsforbruget ved returnering af tomme containere er minimalt.It is a very attractive way of handling fluids in that it is not only liquids, but also granules and other grain material, since the transport volume 20 has a high utilization rate in contrast to other types of containers, such as barrels and tanks. At the same time, the containers are collapsible, whereby the space consumption when returning empty containers is minimal.
25 Der er ofte tale om transport af farlige væsker, hvorfor væskecontainere af den art skal besidde en god modstandsdygtighed over for ydre påvirkninger. Der er her især tale om, at containerrammen trods nogen deformation ikke må beskadige posen med fluidet. Containeren skal således væ-30 re i stand til at falde fra ca. 1 meters højde, uden at posens indhold slipper ud, for at opfylde de krav, der fra myndighedernes side stilles for, at den må anvendes til transport af farligt gods. Efter en sådan påvirkning skal posen fortsat holde tæt. Det er derfor et krav, åt 35 der i containeren ikke findes skarpe hjørner eller kanter, der ved ydre påvirkninger vil kunne beskadige posen.25 Dangerous liquids are often transported, which is why fluid containers of this kind must have good resistance to external influences. In particular, it is the case that, despite any deformation, the container frame must not damage the bag with the fluid. The container must thus be capable of falling from approx. 1 meter height, without the contents of the bag escaping, to meet the requirements set by the authorities for it to be used for transporting dangerous goods. After such an impact, the bag must continue to hold tight. It is therefore a requirement that in the container there are no sharp corners or edges that could damage the bag by external influences.
Det har således vist sig, at den hidtil anvendte måde med DK 168889 B1 2 at fastgøre bunden til rammen ved svejsning kræver uforholdsmæssigt store godspartier for at kunne holde, samtidig med at en brudzone ved svejsningerne ofte har skarpe grater, der vil kunne beskadige posen.Thus, it has been found that the method so far used with DK 168889 B1 2 to attach the bottom to the frame by welding requires disproportionate freight portions to be able to hold, while a fracture zone at the welds often has sharp burrs that can damage the bag.
55
Selvom bundkarret understøttes af væskecontainerens tværeller langsgående afstivningselementer i bunden, vil ydre påvirkninger, der medfører selv små deformationer af væskecontainerens rammekonstruktion, kunne bevirke, at der 10 dannes grater, der kan ødelægge posen med lækage til følge. Det er især bundkarrets fastgørelse til den øvrige bund, der er kritisk, da hele massen af fluidet i posen under transport hviler på bundkarret, hvorfor en ydre påvirkning vil medføre en ekstrem belastning netop på bund-15 karrets befæstigelsesområde til den øvrige bund.Although the bottom vessel is supported by the liquid container's transverse or longitudinal stiffening elements at the bottom, external stresses, which cause even small deformations of the liquid container's frame structure, may cause the formation of burrs which can damage the bag resulting in leakage. It is especially the attachment of the bottom vessel to the other bottom that is critical, since the entire mass of the fluid in the bag during transport rests on the bottom vessel, which is why an external influence will cause an extreme load precisely on the area of the bottom vessel to the other bottom.
Opfindelsen har derfor til formål at angive en bundkar-konstruktion, hvor bundkarret er fæstnet til den øvrige bund på en måde, så at bundkarret tillades nogen deforma-20 tion uden risiko for, at der frembringes skarpe kanter vendende mod posen.The invention therefore aims to provide a bottom vessel structure in which the bottom vessel is attached to the other bottom in such a way that the bottom vessel is allowed some deformation without the risk of sharp edges facing the bag being produced.
Med den i krav l's kendetegnende del angivne bund løses de ovenfor omtalte problemer, idet der langs metalbund-25 karrets kant er tilvirket en krave med nedragende kant, der bringes i indgreb med en komplementær kanal på bundrammen. Hermed vil de skarpe kanter på henholdsvis bundrammen og bundkarret være optaget i respektive kanaler, hvor de bidrager til at give bunden dens mekaniske styr-30 ke. Bundkarret vil fortrinsvis være fremstillet ved formpresning af en metalplade, så at karrets centrale dele er lavere beliggende end periferien. Samtidigt vil bundkarret med fordel kunne være udformet med en åbning til optagelse for et afløb for containerposen, hvorigennem ud-35 tømningen finder sted.With the bottom of the characterizing part of claim 1, the above-mentioned problems are solved as a downwardly extending collar is formed along the edge of the metal bottom vessel, which is engaged by a complementary channel on the bottom frame. Hereby, the sharp edges of the bottom frame and the bottom vessel, respectively, will be accommodated in respective channels where they contribute to giving the bottom its mechanical strength. The bottom vessel will preferably be made by molding a metal plate so that the central parts of the vessel are lower than the periphery. At the same time, the bottom vessel may advantageously be provided with an opening for receiving a drain for the container bag through which the discharge takes place.

Ved at bundrammen og bundkarret er udformet med to samvirkende, ombukkede pladedele, der er i indbyrdes indgreb, vil der være tilvejebragt en vis fjedring i indgrebsområdet, og denne fjedring vil i nogen grad dæmpe 5 kraftige impulser hidrørende fra ydre påvirkninger. Hvis påvirkningerne er så store, at bundrammen og bundkarret påføres en permanent deformation i indgrebsområdet, vil netop de ombukkede pladedele sikre, at der ikke vil være nogen skarpe kanter, som kan lædere posen, så længe der 10 fortsat er tale om et indgreb mellem bundkar og bundramme. De skarpe kanter vil fortsat være optaget i bundkarrets og bundrammens respektive rundtgående kanaler. Først når parterne bringes ud af indgreb vil der forekomme skarpe kanter, men dette sker for en korrekt dimensione-15 ret konstruktion først ved meget kraftige påvirkninger.By forming the bottom frame and the bottom vessel with two interlocking, folded plate parts that are mutually engaged, some spring will be provided in the engagement area, and this spring will attenuate to some extent 5 strong impulses arising from external influences. If the stresses are so large that the bottom frame and the bottom vessel are subjected to permanent deformation in the engagement area, the precisely folded plate parts will ensure that there will be no sharp edges that can leather the bag, as long as there is an engagement between the bottom vessels and bottom frame. The sharp edges will continue to be occupied by the respective circumferential channels of the bottom vessel and the bottom frame. Only when the parties are disengaged will sharp edges appear, but this is done for a properly dimensioned construction only at very strong forces.
Bundkarrets rand eller sidevægge strækker sig skråt opad, hvorved koblingen mellem bundkarret og bundrammen belastes mindst mulig ved fald. En væsentlig del af belastnin-20 gen omsættes til indre trækkræfter i bundkarrets sidevægge. Denne effekt har vist sig mest udtalt, når bundkarrets sidevægge danner en vinkel med lodret i størrelsesordenen 10-30 og en vinkel på ca. 15° foretrækkes af hensyn til nævnte kraftreduktion samt ud fra fremstil-25 lingstekniske ønsker.The rim of the bottom vessel or side walls extends obliquely upwards, whereby the coupling between the base vessel and the bottom frame is least stressed when falling. A substantial part of the load is converted to internal tensile forces in the sidewalls of the bottom vessel. This effect has been most pronounced when the bottom walls of the bottom vessel form an angle of vertical of the order of 10-30 and an angle of approx. 15 ° is preferred for the sake of said power reduction as well as from the manufacturing technical requirements.
Bundkarrets kant ombukkes ved valsning eller rulning. Bundens kanal er tilvejebragt ved ombukning af udragende pladedele fra bundrammens horisontalt anbragte bjælker.The edge of the bottom vessel is folded by rolling or rolling. The bottom channel is provided by folding out protruding plate parts from the horizontally arranged beams of the bottom frame.
30 Hermed vil bundkarret være koblet direkte til rammens bærende dele. Bundrammen vil fortrinsvis være kvadratisk og bundkarret kan dimensioneres, så det optages i rammekonstruktionens kanal ved formpasning. Hermed vil bundkarret blive anbragt i forbindelse med fremstillingen og ikke 35 kunne adskilles fra bundrammen efterfølgende.30 The bottom vessel will be connected directly to the supporting parts of the frame. The bottom frame will preferably be square and the bottom vessel can be dimensioned so that it is accommodated in the channel of the frame structure by molding. Hereby, the bottom vessel will be placed in connection with the manufacture and cannot be separated from the bottom frame subsequently.

Dette afløb er beskrevet i en af ansøgeren samme dag indleveret dansk patentansøgning nr. 722/92, og det har en rektangulær flange, der er indrettet til at blive optaget i en fordybning 14 i bundkarrets bund 11.1, and here the focus is particularly on the construction of the bottom. A bottom vessel 10, which in the illustrated embodiment is rectangular, has a flat bottom surface 11, which is provided with a rectangular hole 12 arranged to accommodate 25 a drain from a plastic bag not shown. This drain is described in a Danish patent application no. 722/92 filed by the applicant on the same day and has a rectangular flange arranged to be accommodated in a recess 14 in the bottom 11 of the bottom vessel.

Bundkarret har skrå sidevægge 13, der danner en vinkel på ca. 15° med lodret. Siderne 13 er opadtil ombukket, så at selve kanten strækker sig lidt nedad igen. Dette er forklaret i forbindelse med fig. 3. Bundkarret kan være 35 fremstillet ved formpresning af en metalplade, hvor sidevæggene til sidst er valset, så at der derfra strækker sig en nedadragende kant. Hullet 12 er stanset ud til DK 168889 B1 5 sidst.The bottom vessel has inclined side walls 13 which form an angle of approx. 15 ° with vertical. The sides 13 are folded upwards so that the edge itself extends slightly downward again. This is explained in connection with FIG. 3. The bottom vessel may be formed by molding a metal plate, the side walls being eventually rolled so that a downwardly extending edge extends therefrom. The hole 12 is punched out to DK 168889 B1 5 last.
Alternativt kan bundkarret fremstilles af en plastplade ved vakuumformning. Dvs. plastpladen anbringes over en 5 matrice med bundkarrets endelige form, hvorpå plastpladen varmes op og formgives ved, at luften mellem matricen og pladen suges bort. Selv om plast umiddelbart er et svagere materiale end metal, vil man med en passende formgivning af bundkarret kunne opnå den fornødne trækstyrke.Alternatively, the bottom vessel may be made of a plastic sheet by vacuum forming. Ie the plastic plate is placed over a die with the final shape of the bottom vessel, whereupon the plastic plate is heated and shaped by sucking away the air between the die and the plate. Although plastic is immediately a weaker material than metal, with the proper shaping of the bottom vessel it will be possible to achieve the required tensile strength.

Selve væskecontaineren har en bundkonstruktion 20 samt en overdel, hvoraf kun de opstående standere 30 og overliggerne 32 er vist. Dette er gjort for at illustrere formen af væskecontaineren. Bunden 20 omfatter ved den foretruk-15 ne udførelsesform tre gennemgående ben 22 af plademetal. Dette er i praksis tilvejebragt med en bølgeformet plade med regulære trapezbølger. Den bølgeformede plade kan være fæstnet til den øvrige del af bundrammen ved svejsning eller udgøre en integreret part af denne. Bunden har der-20 udover fire sider 24, 25, der tilvejebringer en kasseform for selve bunden. Bunden kan yderligere afstives med et antal tværstivere 26 efter behov. Siderne 24 og 25 afsluttes opadtil, så der indadtil dannes en opad åben, rundtgående kanal, der bedre fremgår af fig. 2.The liquid container itself has a bottom structure 20 and an upper part, of which only the upright stands 30 and the overlays 32 are shown. This is done to illustrate the shape of the liquid container. The bottom 20, in the preferred embodiment, comprises three through-legs 22 of sheet metal. This is in practice provided with a corrugated plate with regular trapezoidal waves. The corrugated plate may be attached to the other part of the bottom frame by welding or form an integral part thereof. The bottom has, in addition to four sides 24, 25, which provides a box shape for the bottom itself. The bottom can be further stiffened with a number of cross struts 26 as needed. Pages 24 and 25 terminate upwardly so that inwardly, an upwardly open, circumferential channel is formed, which is better seen in FIG. 2nd
25 På fig. 2 ses i snit en del af siden 25, idet det ses, at den bølgeformede plade fortsætter opadtil. Det ses, hvorledes siden 25 danner en vinkel med siden 22. Opadtil afsluttes siden 22 med en kant 41. Inden for denne kant er 30 der en opad åben rundtgående kanal 42. Mellem kanalen 42 og siden 25 er der en rektangulær kanal 40, hvori afstivningselementer kan anbringes efter behov.25 In FIG. 2 is a sectional view of part 25, showing that the corrugated plate continues upward. It is seen how the side 25 forms an angle with the side 22. Upwardly, the side 22 terminates with an edge 41. Within this edge, there is an upwardly open circumferential channel 42. Between the channel 42 and the side 25 there is a rectangular channel 40 in which stiffening elements can be placed as needed.
På fig. 3 ses hvorledes bundkarret 10 optages i kanalen 35 42, hvilket sker ved, at sidevæggen 13's rand 16 ombukkes til dannelse af en nedadragende kant 18. Væskecontainerens indhold vil presse bundkarret 10 nedad, hvilket vil DK 168889 B1 6 frembringe indre spændinger i sidevæggen 13. Sidevæggen 13 danner ved den foretrukne udførelsesform en vinkel på 15° med lodret, hvilket skaber en vis fleksibilitet i bundkonstruktionen, idet det kraftige træk i vid udstræk-5 ning vil kunne absorberes af dels sidevæggen og dels en vis bevægelighed i den på sidevæggen 25 dannede kanalkonstruktion 41, 42. Samtidig vil selve bundkarret blive understøttet af tværstiverne 26 og pladedelene 21 mellem de U-formede ben 22 på det bølgeformede pladeelement 10 (fig· 1). Det bemærkes, at overgangen (fig. 3) mellem bundkarrets sidevægge 13 og den øvre afslutning 41 på bundrammens side foregår uden skarpe kanter. Dette er særdeles vigtigt, når der tænkes på, at væskecontaineren er indrettet til at indeholde en pose af tyndt plastmate-15 riale med væsken.In FIG. 3, it is seen how the bottom vessel 10 is received in the channel 35 42, which is caused by the edge 16 of the sidewall 13 being bent to form a downwardly projecting edge 18. The contents of the liquid container will push the bottom vessel 10 downwards, which will create internal stresses in the side wall 13. The sidewall 13, in the preferred embodiment, forms an angle of 15 ° with the vertical, which creates some flexibility in the bottom structure, since the strong feature can be largely absorbed by the sidewall and partly a movement in the sidewall 25 formed. channel structure 41, 42. At the same time, the bottom vessel itself will be supported by the transverse struts 26 and the plate portions 21 between the U-shaped legs 22 of the corrugated plate element 10 (Fig. 1). It should be noted that the transition (Fig. 3) between the bottom walls of the bottom vessel 13 and the upper end 41 on the side of the bottom frame takes place without sharp edges. This is particularly important when considering that the liquid container is arranged to contain a bag of thin plastic material with the liquid.
På fig. 4 er en detalje af bundkarret vist, hvor det ses, at bunden 11 omkring hullet 12 er forsænket i et område 14, hvor dette område har en udstrækning L svarende til 20 afløbets flange. Denne forsænkning 14 er indrettet til at kunne optage og styre et afløb, hvorigennem man ved adgang i det midterste U- formede ben (fig. 1) vil kunne udtømme væskecontainerens indhold.In FIG. 4, a detail of the bottom vessel is shown, where it is seen that the bottom 11 around the hole 12 is recessed in an area 14 where this area has an extension L corresponding to the drain flange 20. This recess 14 is adapted to accommodate and control a drain through which, upon entry into the middle U-shaped leg (Fig. 1), it will be possible to discharge the contents of the liquid container.
25 Samtidig ses sidevæggen 13’s afslutning opadtil, hvor det vil være klart for en fagmand, at man med denne form tilvej ebringer en vis fjedring, hvormed det er muligt at absorbere en del af de påvirkninger en væskecontainer udsættes for under den daglige håndtering.25 At the same time, the end of the side wall 13 is seen facing upwards, where it will be clear to a person skilled in the art that this form provides a certain amount of suspension, with which it is possible to absorb some of the influences to which a liquid container is exposed during daily handling.

Størrelsen af bundkarret vil fortrinsvis være således, at bundkarret 10 ved anbringelse i den rundtgående kanal 42 presser kanalens bagvæg 42a i en retning mod ydervæggen 25. Hermed vil bundkarret, når det først er anbragt være 35 vanskeligt at udtage igen, hvorfor yderligere fastgørelse i form af svejsning eller lignende er unødvendig.The size of the bottom vessel will preferably be such that, when placed in the circumferential channel 42, the bottom vessel 10 presses the rear wall 42a of the channel in a direction towards the outer wall 25. Thus, once it has been placed, the bottom vessel will be difficult to take out again, so further attachment in form of welding or the like is unnecessary.
