Abstract

A base section for a folding container for carrying a liquid comprises a rectangular base section 1, two opposing end sections 2;3 and two opposing side sections 4;5, which are each pivotally connected to one of the four sides of the base section, a top section 6, which is pivotally connected to a side section 4;5 or an end section 2;3, and a liner for storing the liquid. The base section 1 comprises a base frame 8 having two opposing end members 9;10, two opposing side members 11;12, a number of cross-members 13, which connect the side members 11;12 and a base 14, which lies on the cross- members. Along two opposing sides of the base 14 upright flaps 16 are formed, which with the base free have a distance a between them at the upper edges 17 that is greater than the width b of the base. The opposing side faces of the side members 11;12 have a lower section 19, which at a given point along the side members 11;12 extends upward from the cross-members 13 to a height h' largely corresponding to the height h of the base flaps 16 at the same point in the longitudinal direction, and an upper section 20, which extends upwards as an extension of the lower section 19. The distance between the opposing faces of the side members 11;12 is greater than the width b of the base both at the lower and at the upper section 19;20, while the distance c between the two lower sections is less than the distance a between the upper edges of the flaps when the base is free. This means that the base 14 can be fixed to the base section more cheaply and more easily than hitherto known. <IMAGE>

Description

Opfindelsen angår en bundsektion til en foldecontainer til transport af en væske, hvor foldecontaineren omfatter én i hovedsagen rektangulært udformet bundsektion, to modstående gavlsektioner og to modstående sidesektioner, som svingbart er 5 forbundet med hver sin af bundsektionens fire sider, en topsektion, som svingbart er forbundet med en sidesektion eller en gavlsektion, og en liner til opbevaring af væsken, og hvor bundsektionen omfatter en bundramme med to modstående gavlbjælker, to modstående sidebjælker, et antal tværbjælker, 10 som forbinder sidebjælkerne, og en bund, som ligger på tværb j ælkeme.The invention relates to a bottom section for a folding container for transporting a liquid, the folding container comprising one substantially rectangular shaped bottom section, two opposite end sections and two opposite side sections, pivotally connected to each of the four sides of the bottom section, a top section which is pivotally connected to a side section or gable section, and a liner for storing the liquid, the bottom section comprising a bottom frame with two opposing gable beams, two opposing side beams, a number of cross beams, 10 connecting the beams, and a bottom lying on the transverse beams. .

Transport af væsker finder i stort omfang sted i transportable genbrugsbeholdere, der ofte fyldes ét sted og tømmes et andet i 15 større eller mindre afstand fra det første. De tomme beholdere vejer selvsagt mindre end de fyldte, men den plads, de optager, er uændret, når containerne er faste, således som det eksempelvis er tilfældet med ståltanke. Disse faste beholdere er derfor kostbare og besværlige at returnere, når de skal 20 fyldes påny.The transport of liquids takes place largely in transportable recycling bins, which are often filled in one place and emptied in another at greater or less distances from the first. The empty containers obviously weigh less than the filled ones, but the space they occupy is unchanged when the containers are fixed, as is the case with steel tanks, for example. These fixed containers are therefore expensive and cumbersome to return when they need to be refilled.

<<

Med henblik på at afhjælpe denne mangel er der udviklet væskecontainere, som efter tømning kan bringes til at antage et stærkt reduceret volumen. Disse containere består hver af en 25 fleksibel liner i form af en stor sæk og en kasse med vægformede sektioner, der er hængslet på en pallelignende bundsektion. Sektionerne kan foldes op omkring lineren og derved støtte den væskefyldte, fleksible liner på alle sider.In order to remedy this deficiency, fluid containers have been developed which, after emptying, can be made to assume a greatly reduced volume. These containers each consist of a 25 flexible liner in the form of a large sack and a box of wall-shaped sections hinged on a pallet-like bottom section. The sections can be folded around the liner, thus supporting the fluid-filled, flexible liner on all sides.

30 Når lineren er tom, kan sektionerne foldes sammen i en stabel over bundsektionen, og lineren kan fladlægges. I denne tilstand fylder containeren forholdsvis lidt.30 When the liner is empty, the sections can be folded into a stack above the bottom section and the liner can be flattened. In this state, the container fills relatively little.

I bundsektionen findes almindeligvis en pladeformet bund til at 35 bære vægten af væsken i en fyldt liner. Denne bund er typisk svejset fast i bundsektionen. Dette arbejde er imidlertid 2 DK 173692 B1 kostbart og besværligt, især når bundsektionen og dens bund er fremstillet af galvaniseret jern, således som det ofte |er tilfældet.In the bottom section there is usually a plate-shaped bottom for carrying the weight of the liquid in a filled liner. This bottom is typically welded to the bottom section. However, this work is expensive and cumbersome, especially when the bottom section and its bottom are made of galvanized iron, as is often the case.

5 Alternativt kan bunden nittes eller skrues fast på bundsektionen, men dette arbejde er tidsrøvende og derfor ligeledes kostbart.Alternatively, the bottom may be riveted or screwed onto the bottom section, but this work is time consuming and therefore also costly.

Formålet med opfindelsen er at anvise en bundsektion af den 10 indledningsvis nævnte art, som har en bund, der er billigere og lettere at fastgøre i bundsektionen end hidtil kendt.The object of the invention is to provide a bottom section of the type mentioned initially, which has a bottom that is cheaper and easier to attach to the bottom section than hitherto known.

Det nye og særegne ifølge opfindelsen, hvorved dette opnås består i, at der langs to modstående sider på bunden er 15 udformet opretstående flige, som i bundens frie tilstand har større indbyrdes afstand ved overkanterne, end bunden er bred, at sidebjælkernes modstående sideflader hver har et necre afsnit, der et givet sted langs sidebjælkerne strækker sig opefter fra tværbjælkerne i én til bundfligenes højde på sanme 20 sted i længderetningen i hovedsagen svarende højde, og et øvre afsnit, der strækker sig opefter i forlængelse af det necre afsnit, at den indbyrdes afstand mellem sidebjælkernes modstående sideflader er større end bundens bredde ved såvel det nedre som øvre afsnit, mens den indbyrdes afstand mellem de 25 to nedre afsnit er mindre end den indbyrdes afstand mellem fligenes overkanter i bundens frie tilstand. Derved kan bunden i én enkel operation umiddelbart trykkes ned i bundsektionen, hvor den da automatisk låses fast.The new and peculiar according to the invention, whereby this is achieved consists in the fact that upright tabs are formed along two opposite sides of the bottom which in the free state of the bottom have a greater mutual spacing at the upper edges than the bottom is wide, that the opposite side faces of the side beams each have a lower section extending at a given location along the side beams upward from the crossbeams at a height of one to the bottom tabs at approximately 20 longitudinal directions substantially corresponding to the elevation, and an upper section extending upwardly of the lower section so that it is mutually the distance between the opposite side faces of the side beams is greater than the width of the bottom at both the lower and upper sections, while the distance between the two two lower sections is less than the distance between the upper edges of the tabs in the free state of the bottom. This allows the bottom in a single operation to be immediately pressed down into the bottom section, where it is automatically locked.

30 Fastlåsningen sikres effektivt, når det nedre afsnit går over i det øvre afsnit langs et tværgående kantområde, der strækker sig på tværs af den respektive sideflade.The locking is effectively secured when the lower section extends into the upper section along a transverse edge region extending across the respective side surface.

Bunden bliver særlig billig at fremstille, når fligene og 35 bunden er udformet ud i et af samme plade. Dette kan eksempelvis finde sted ved kantbukning af pladen. Pladen kan i 3 DK 173692 B1 afhængighed af det anvendte plademateriales egenskaber i nogle tilfælde bukkes en vinkel på omkring 90®, hvorved pladens naturlige spring back sikrer, at afstanden mellem fligenes overkanter bliver lidt større end bundens bredde.The bottom becomes particularly inexpensive to manufacture when the tabs and bottom are formed in one of the same plate. This can take place, for example, by edge bending the plate. In some cases, the plate can be bent at an angle of about 90 °, depending on the properties of the sheet material, whereby the natural spring back of the plate ensures that the distance between the upper edges of the tabs is slightly greater than the width of the bottom.

Det er fordelagtigt, når bunden danner en spids vinkel med hver flig på mellem 60® og 89®, fortrinsvis mellem 75® og 89®, og især mellem 85® og 89®.It is advantageous when the bottom forms an acute angle with each tab between 60® and 89®, preferably between 75® and 89®, and especially between 85® and 89®.

10 Ved en foretrukket udførelsesform kan de to modstående sidebjælker hver består af en nedre og øvre bjælke, hvorved det tværgående kantområde dannes af et ud over den nedre bjælke ragende stykke af undersiden på den øvre bjælke.In a preferred embodiment, the two opposite side beams may each consist of a lower and upper beam, whereby the transverse edge region is formed by a piece extending beyond the lower beam of the underside of the upper beam.

15 For at lette tømningen af en fyldt liner kan bunden med fordel være anbragt med fald mod en gavlbjælke, hvori der er udformet en åbning til en udløbstud til containerens liner.Advantageously, to facilitate the emptying of a filled liner, the bottom may be disposed with a fall toward a gable beam, in which is provided an opening for an outlet spout for the container liner.

Bunden låses ekstra godt fast i bundsektionen, når der langs de 20 to andre modstående sider af bunden er udformet andre opretstående flige, der er indrettet til at samvirke med gavlbjælkemes modstående sideflader på samme måde som de første modstående flige på bunden samvirker med sidebjælkemes modstående sideflader.The bottom is extra tightly locked in the bottom section when other upright tabs are formed along the other two opposite sides of the bottom, which are adapted to cooperate with the facing side faces of the girders in the same way as the first opposing tabs on the bottom cooperate with the opposite side faces of the side beams. .

Opfindelsen forklares nærmere nedenfor, idet der beskrives en alene eksempelvis udførelsesform under henvisning til tegningen, hvor 30 fig. 1 viser, set i perspektiv, en foldecontainer med en bundsektion ifølge opfindelsen, fig. 2 viser, set i perspektiv, et sprængbillede af den i fig.The invention will be explained in more detail below, by way of example only, by way of example, with reference to the accompanying drawings, in which: FIG. 1 is a perspective view of a folding container having a bottom section according to the invention; FIG. 2 is a perspective view of the exploded view of FIG.

Den i fig. 1 viste foldecontainer er beregnet til opbevaring cg transport af en væske, som herunder befinder sig i en liner «f form som en stor sæk af eksempelvis plast. Den fyldte liner er ikke i sig selv formbestandig og den støttes derfor langs der,s 10 samlede yderside af i alt seks sektioner i form af faste vægge, der svingbart er forbundet med hinanden og i udfoldet tilstar.d danner en lukket kasse med et kammer til opbevaring af lineren.The FIG. 1 is intended for storage and transport of a liquid, which is contained in a liner in the form of a large bag of, for example, plastic. The filled liner is not in itself mold resistant and is therefore supported along there, s 10 total exterior of a total of six sections in the form of fixed walls that are pivotally connected to each other and in unfolded tilstar.d form a closed box with a chamber for storing the liner.

Når lineren er tømt, kan disse vægge foldes sammen, således at 15 de kommer til at ligge i en stabel oven på hinanden (ikke vist). I denne sammenfoldede tilstand fylder containeren forholdsvis lidt, og den kan derfor nu bekvemt og økonomiiik fordelagtigt returneres for at blive fyldt påny.When the liner is emptied, these walls can be folded together so that they will lie in a stack on top of each other (not shown). In this collapsed state, the container fills relatively little, and therefore it can now conveniently and economically be returned to be refilled.

20 Containerens seks vægge er en bundsektion 1, to modstående gavlsektioner 2;3, to modstående sidesektioner 4;5 og en topv«»g 6, der i fig. 1, som vist med pilen, er ved at blive ført op i sin slutstilling oven på gavl- og sidesektionerne.The six walls of the container are a bottom section 1, two opposite end sections 2; 3, two opposite side sections 4; 5 and a top wall 6, which in FIG. 1, as shown by the arrow, is being raised to its final position on top of the gable and side sections.

25 Bundsektionen er udformet som en palle med ben 7, der tillader gaflerne på en gaffeltruck (ikke vist) at blive ført ind under bundsektionen, således at gaffeltrucken sættes i stand til at løfte containeren.The bottom section is designed as a pallet with legs 7 which allows the forks of a forklift truck (not shown) to be brought under the bottom section, so that the forklift is enabled to lift the container.

30 Foldecontaineren er nærmere beskrevet i ansøgerens offentliggjorte patentansøgninger no. WO 00/30946, og ψΟ 00/30945, 35 Bundsektionen 1 omfatter en bundramme 8 med to modstående gavlbjælker 9 og 10, to modstående sidebjælker 11 og 12, et 5 DK 173692 B1 antal tværbjælker 13, som forbinder sidebjælkerne, og en pladeformet bund 14, som ligger på tværbjælkerne (fig. 5} med hældning mod et udløb 15 for linerens udløbstud (ikke vist) ved den forreste gavlbjælke 9.30 The folding container is further described in the applicant's published patent applications no. WO 00/30946, and ψΟ 00/30945, 35 The bottom section 1 comprises a bottom frame 8 with two opposite end beams 9 and 10, two opposite side beams 11 and 12, a number of cross beams 13 connecting the side beams, and a plate-shaped bottom 14, which lies on the transverse beams (Fig. 5} with an inclination towards an outlet 15 for the liner outlet spigot (not shown) at the front end beam 9.

55

Bunden 14 består af en plade af eksempelvis metal, såsom galvaniseret jern. Som vist i fig. 2 og 3 har pladen langs hver af bundens sider en ombøjet flig 16 med overkanter 17. Pligenes højde h er så meget større ved bundens forkant end ved dens 10 bagkant, at overkanterne kommer til at ligge i hovedsagen horisontalt, når bunden befinder sig på sin plads i bundrammen.The bottom 14 consists of a sheet of, for example, metal, such as galvanized iron. As shown in FIG. 2 and 3, the plate along each side of the bottom has a bent tab 16 with upper edges 17. The height h of the lugs is so much greater at the front edge of the bottom than at its rear edge that the upper edges will lie substantially horizontally when the bottom is on its space in the bottom frame.

Ved forkanten har bunden desuden en udskæring 18 til linerens udløbstud.At the leading edge, the bottom also has a cutout 18 for the liner outlet spigot.

15 Som vist i fig. 3 er afstanden a mellem fligene 16's overkanter 17 større end bundens bredde b, idet hver flig 17 danner en spids vinkel α med bunden 14.15 As shown in FIG. 3, the distance a between the upper edges 17 of the tabs 16 is greater than the width b of the bottom, each tab 17 forming an acute angle α with the bottom 14.

Sidebjælkemes 11;12 modstående sideflader 19,20 har et nedre 20 afsnit 19, der strækker sig opefter i en højde h’ fra det skrå plan, som tværbjælkerne 13 danner, og et øvre afsnit 20, der via et tværgående kantområde 21 strækker sig opefter i forlængelse af det nedre afsnit 19.The opposite side faces 19,20 of the lateral beams 11; 12 have a lower portion 20 extending upwardly at a height h 'from the inclined plane formed by the transverse beams 13, and an upper portion 20 extending via a transverse edge region 21 following the lower section 19.

25 Det nedre afsnits højde h' er ligesom bundfligenes højde h større ved bundens forkant end ved dens bagkant. Samme sted, set i længderetningen, er det nedre afsnits højde h* lig med eller lidt større end bundfligenes højde h.The height h 'of the lower section, like the height of the bottom tabs h, is larger at the front edge of the bottom than at its rear edge. In the same place, seen longitudinally, the height of the lower section is equal to or slightly greater than the height h of the bottom tabs.

30 Afstanden d mellem de to nedre modstående afsnit 19 er større end afstanden c mellem de to øvre modstående afsnit 20. Afstanden d mellem de to nedre modstående afsnit 19 er desuden mindre end afstanden a mellem fligene 16's overkanter 17.In addition, the distance d between the two lower opposite sections 19 is greater than the distance c between the two upper opposing sections 20. The distance d between the two lower opposite sections 19 is also smaller than the distance a between the upper edges 17 of the tabs 16.

35 Som vist i fig. 3 og 4 skydes bunden 14 ved montering i pilenes retning ned i bundrammen 8. Herunder kan bunden passere mellem 6 DK 173692 B1 de to øvre afsnit 20, da afstanden c mellem disse er større efnd bundens bredde b. _35 As shown in FIG. 3 and 4, the bottom 14 is slid by mounting in the direction of the arrows down into the bottom frame 8. Below this the bottom can pass between the two upper sections 20, since the distance c between them is greater than the width of the bottom b.

Selv om afstanden a mellem fligene 16's overkanter 17 er større 5 end afstanden c mellem de to øvre afsnit 20, kan fligene alligevel passere mellem disse afsnit, idet fligene 16 herunder fjedrene bøjes ind mod hinanden.Although the distance a between the upper edges 17 of the tabs 16 is greater than the distance c between the two upper sections 20, the tabs can nevertheless pass between these sections, with the tabs 16 including the springs being bent towards each other.

Da afstanden d mellem de to nedre afsnit 19 også er større (ind 10 bunden 14's bredde b, kan bunden 14 skydes helt ned i bundrammen 8 til anlæg mod tværbjælkerne 13.Since the distance d between the two lower sections 19 is also greater (within the width b of the bottom 14), the bottom 14 can be pushed all the way down into the bottom frame 8 for abutment against the beams 13.

Da det nedre afsnit 19's højde h' ved ethvert sted i længderetningen er lig med eller lidt større end bundfligone 15 16's højde h samme sted, springer fligene 16 nu fjedrene :.nd mod de nedre afsnit 19 med fligenes overkanter 17 anbragt under de tværgående kantområder 21. Fligene virker nu som en slags modhager, der effektivt fastlåser bunden i bundraxnmen 8.Since the height h 'of the lower section 19' at any point in the longitudinal direction is equal to or slightly greater than the height h of the bottom tab 15 16, the tabs 16 now spring the springs:. 21. The tabs now act as a kind of barbs, effectively locking the bottom of the bottom frame 8.

20 Når de tværgående kant områder 21’s bredde e svarer til bundfligenes tykkelse t, opnås fordelagtigt en glat og j<svn overgang mellem de øvre afsnit 20's sideflader og den indvendige side af fligene 16.When the width e of the transverse edge regions 21 corresponds to the thickness t of the bottom tabs, a smooth and smooth transition between the lateral surfaces of the upper sections 20 and the inner side of the tabs 16 is advantageously achieved.

25 Som det fremgår, er bunden på denne måde nu hurtigt og n;mt blevet monteret i bundrammen uden nogen form for kostbare sammenføjninger, såsom svejsninger, skruesamlinger el Ler nittesamlinger.25 As can be seen, the bottom in this way has now quickly and virtually been mounted in the bottom frame without any costly joints, such as welds, screw joints or clay rivet joints.

30 I det viste tilfælde består sidebjælkerne 11 og 12 hver af en nedre bjælke 22 og en øvre bjælke 23. Det tværgående kantområde 21, der låser bunden 14 fast i bundrammen 8, dannes af et stykke af undersiden på den øvre bjælke 23, der rager ud over den nedre bjælke 22.In the case shown, the side beams 11 and 12 each consist of a lower beam 22 and an upper beam 23. The transverse edge region 21, which locks the base 14 in the bottom frame 8, is formed by a piece of the underside of the upper beam 23 which protrudes. beyond the lower bar 22.

35 7 DK 173692 B1 I det ovenfor beskrevne og på tegningen viste eksempel blev bunden kun låst fast langs sidebjælkerne 11 og 12. Alternativt kan bunden på tilsvarende måde være låst fast langs gavlbjælkerne 9 og 10.In the example described and shown in the drawing, the bottom was only locked along the side beams 11 and 12. Alternatively, the bottom may be similarly locked along the gable beams 9 and 10.

55

Bunden behøver heller ikke at være placeret med fald mod et udløb i containeren. I dette tilfælde har bundfligene samme højde i hele deres længdeudstrækning.The bottom also does not have to be positioned with a fall towards an outlet in the container. In this case, the bottom tabs have the same height throughout their length.

10 Desuden kan bundsektionen ifølge opfindelsen også med fordel anvendes til foldecontainere, der skal fragte fast gods.In addition, the bottom section of the invention can also advantageously be used for folding containers to carry solid goods.
