DK 154742 BDK 154742 B

Opfindelsen angår en stablelig container for brug til oplagring og håndtering af fisk ombord på et fiskefartøj, såsom en trawler, med en rektangulær bundvæg, to endevægge, der strækker sig opad fra de modstå-5 ende korte sider af bundvæggen og to sidevægge, som strækker sig opad fra de modstående lange side af bundvæggen -The invention relates to a stackable container for use in the storage and handling of fish on board a fishing vessel, such as a trawler, with a rectangular bottom wall, two end walls extending upward from the opposing short sides of the bottom wall and two side walls extending rise upward from the opposite long side of the bottom wall -

Det er kendt at emballere fisk og is i forholdsvis små kasser med en kapacitet på ca. 40-50 kg og at 10 oplagre disse kasser ved stabling af dem i lastrummet. Emballering i sådanne kasser medfører høje arbejdsomkostninger, og de anvendte kasser og den benyttede håndteringsmåde medfører, at lastrummets volumen ikke kan udnyttes effektivt. Dertil kommer, at emballering i 15 sådanne kasser ikke tillader, at kasserne med fisk kan losses med høje hastigheder fra lstrummet ved hjælp af mekanisk udstyr, såsom hejsepparater.It is known to pack fish and ice in relatively small boxes with a capacity of approx. 40-50 kg and to 10 store these boxes by stacking them in the cargo compartment. Packaging in such boxes incurs high labor costs, and the boxes used and the method of handling used mean that the cargo volume cannot be utilized efficiently. In addition, packaging in 15 such boxes does not allow the boxes of fish to be unloaded at high speeds from the cargo compartment by mechanical equipment such as hoists.

Det er hensigten med opfindelsen at tilvejebringe en container af den i indledningen angivne art, og 20 som ikke har de omtalte ulemper, hvilken container især er egnet til anvendelse i forbindelse med f.eks. et i DK patentansøgning nr. 3363/83 beskrevet udstyr til containerisering og håndtering af fisk ombord på et fiskefartøj , der har et arbejdsdæk, i det mindste ét la-25 strum under arbejdsdækket og en langsgående luge gennem arbejdsdækket strækkende sig i længde over hovedsagelig hele længden af lastrummet og midler til at transportere containere under og over arbejdsdækket.It is an object of the invention to provide a container of the kind specified in the preamble and 20 which does not have the aforementioned disadvantages, which container is particularly suitable for use with e.g. a device described in DK patent application no. 3363/83 for containerisation and handling of fish on board a fishing vessel having a working deck, at least one la-ridge below the working deck and a longitudinal hatch through the working deck extending in length over substantially the whole the length of the cargo compartment and means for carrying containers under and above the working deck.

Dette udstyr adskiller sig fra andet kendt ud-30 styr ved, at containerne omfatter flere ens, stablelige fiskecontainere, der hver har matchende modstående flanger, der strækker sig opad fra containeren ved modstående sider af denne, og et bundparti, der er udformet til stabl.ingsindgreb med topflangerne af en 35 lignende, derunder stablet container, hvilke flanger har modstående gribesteder, hvorved den øverste contai-This equipment differs from other known equipment in that the containers comprise several identical, stackable fishing containers, each having matching opposing flanges extending upward from the container at opposite sides thereof, and a bottom portion designed for stacking. engaging with the top flanges of a similar, stacked container therebetween, which flanges have opposite gripping points,

2 ner i en stabel af containere kan gribes og løftes vertikalt fra stabelen uden at forstyrre containerne i tilgrænsende stabler, og midlerne til at transportere containere omfatter et hejseorgan, der er anbragt under 5 arbejdsdækket, og som er indrettet til selektivt at gribe og frigive containerne ved gribestederne og til at transportere containerne mellem valgte positioner i lastrummet, herunder en position direkte under og i flugt med den langsgående luge, og et transportorgan, 10 der er anbragt over arbejdsdækket, og som er indrettet til selektivt at gribe og frigive containerne og til at transportere dem mellem et sted i lastrummet direkte under lugen og i det mindste én arbejdsposition på ar-bej dsdækket.2 containers in a stack of containers can be gripped and lifted vertically from the stack without disturbing the containers in adjacent stacks, and the means for transporting containers comprise a hoisting member located below the 5 working deck, which is adapted to selectively grab and release the containers at the gripping points and for transporting the containers between selected positions in the cargo compartment, including a position directly below and in flight with the longitudinal hatch, and a transport means 10 disposed over the working deck adapted to selectively seize and release the containers and to to transport them between a place in the cargo space directly under the hatch and at least one working position on the working deck.

15 Med dette udstyr muliggøres oplagring af fisk i containere, der har en tilstrækkelig lille indre dybde til at sikre landing af et produkt af høj kvalitet, samtidig med at der opnås en høj volumenudnyttelse af fiskefartøjets lastrum og høje laste- og lossehastig-20 heder under lastning henholdvis losning af lastrummet med containere.15 This equipment enables the storage of fish in containers having a sufficiently small internal depth to ensure the landing of a high quality product, while at the same time achieving a high volume utilization of the fishing vessel's cargo hold and high loading and unloading speeds below loading or unloading of the cargo space with containers.

Containeren ifølge nærværende opfindelse er ejendommelig ved, at sidevæggene har opadragende øvre dele, der strækker sig opad forbi endevæggenes topdele, 25 at sidevæggenes bundafsnit er forsat indad i tilstrækkelig grad til, at containeren har et bundparti, der har en reduceret bredde dimensioneret, så det kan optages mellem de opadragende øvre dele af sidevæggene af en lignende, derunder stablet container, og hvis opad-30 ragende dimension er i hovedsagen lig med den opadragende dimension af sidevæggenes opadragende øvre dele, at den har et laminært låg, der er dimensioneret til tæt pasning mellem sidevæggenes opadragende øvre dele, og ved hvis ender der findes samvirkende elementer til 35 udløselig fastgørelse af låget i en indgrebsposition i et plan parallelt med containeres bund og beliggende i 3The container of the present invention is characterized in that the sidewalls have upwardly projecting upper portions extending upwardly beyond the top portions of the end walls, the bottom portions of the sidewalls being sufficiently inward enough for the container to have a bottom portion having a reduced width dimensioned so that the may be accommodated between the upwardly extending upper portions of the side walls of a similar, beneath, stacked container, and whose upward dimension is substantially equal to the upward dimension of the upwardly extending upper portions of the side having a laminar lid dimensioned to close fit between the upwardly extending upper portions of the sidewalls and at whose ends there are cooperating elements for releasably securing the lid in an engaging position in a plane parallel to the bottom of the container and located in 3

Herved opnås den fordel, at gribestederne på den øverste container i en stabel, selv når containerens låg er påsat, er let tilgængelige for gribemidlerne, 15 der virker mellem containerens opadragende sidevægge, uden at de opadragende sidevægge bevirker, at der ved stablingen af containerne går plads til spilde, idet containerens bundparti er udformet, så det passer ned mellem de opadragende sidevægdele af en neden under 20 stablede container. Dette medfører, at det til rådighed stående lastrumsvolumen udnyttes bedst muligt, udformningen af containeren medfører yderligere den fordel, at en stabel af sådanne containere får en stor tværstyrke.Hereby, the advantage is obtained that the gripping points on the upper container of a stack, even when the lid of the container is fitted, are readily accessible to the gripping means which act between the container's upward side walls, without the upward side walls causing the stacking of the containers to proceed. space for waste, the bottom portion of the container being designed to fit downwardly between the upwardly extending side wall portions of a container below 20 stacked. This means that the available cargo volume is utilized to the best possible extent, the design of the container further gives the advantage that a stack of such containers has a high transverse strength.

25 Låget, der beskytter containerens indhold mod forurening passer tæt mellem sidevæggenes opadragende dele og virker derved sammen med forstærkningsstangen til at styrke og afstive containeren, hvilket'medfører, at højden af containerstablerne i fartøjets lastrum kan 30 forøges.The lid which protects the contents of the container from contamination fits snugly between the upwardly extending parts of the sidewalls and thereby works with the reinforcing bar to strengthen and stiffen the container, which means that the height of the container stacks in the cargo hold can be increased.

En foretrukket udførelsesform for containeren ifølge opfindelsen er ejendommelig ved, at sidevæggene og endevæggene er dobbeltvægge, der består af to indbyrdes adskilte skillevægge og har flere opad forløben-35 de korrugeringer anbragt indbyrdes adskilt langs skillevæggene, at hver korrugering er udformet under con- 4A preferred embodiment of the container according to the invention is characterized in that the side walls and the end walls are double walls consisting of two spaced-apart partitions and having several upwardly extending corrugations spaced apart along the partitions, that each corrugation is formed under the cone.

Ved at udføre containerens side- og endevægge som dobbeltvægge med korrugeringer opnås en let, stærk og varmeisoleret container, der som følge af korrugeringerne giver stabler af sådanne containere en forøget 10 stablingsstyrke.By performing the side and end walls of the container as double walls with corrugations, a light, strong and heat insulated container is obtained which, as a result of the corrugations, provides stacks of such containers with an increased stacking strength.

Opfindelsen forklares nærmere i det følgende ved en udførelsesform under henvisning til tegningen, hvor fig. 1 er et endebillede i snit af en stablelig container ifølge opfindelsen vist uden låg, 15 fig. 2 et sidebillede i snit af containeren i fig. 1 med påsat låg, og fig. 3 et perspektivbillede af containeren i fig. 1.The invention will be further explained in the following by an embodiment with reference to the drawing, in which fig. 1 is a sectional end view of a stackable container according to the invention shown without a lid; FIG. 2 is a side sectional view of the container of FIG. 1 with a fitted lid, and fig. 3 is a perspective view of the container of FIG. First

Den på tegningen viste container er af en dob-20 beltvægget konstruktion og er fremstillet af polyethy-len med høj densitet eller andet materiale med stor styrke, som egner sig til at komme i kontakt med fødevarer. Under containerens fremstilling er en polyure-than skummet på plads inden for de dobbelte vægge for 25 yderligere at afstive containerkonstruktionen og reducere smeltningen af is, som pakkes med fisk i containeren.The container shown in the drawing is of a double walled construction and is made of high density polyethylene or other high strength material suitable for contact with food. During the manufacture of the container, a polyurethane is foamed in place within the double walls to further stiffen the container structure and reduce the melting of ice packaged with fish in the container.

Containerens stablingsstyrke forøges ved anvendelse af en række ydre opadgående korrugeringer l, der 30 - som det bedst fremgår af fig. 3 - er udformet i containerens sidevægge 3 og endevægge 5. Containerens bundvæg 4 er forstærket af en række ydre korrugeringer 6, der ses i tværsnit i fig. 2.The stacking strength of the container is increased by the use of a number of outer upward corrugations 1 which - as best seen in FIG. 3 - is formed in the side walls 3 and end walls of the container 5. The bottom wall 4 of the container is reinforced by a series of outer corrugations 6, which are seen in cross section in FIG. 2nd

lig grad til, at containeren har et bundparti, der har en reduceret bredde dimensioneret, så det kan optages mellem de opadragende øvre dele 7 af sidevæggene 3 af en lignende container, som er stablet derunder.similarly, the container has a bottom portion having a reduced width dimensioned so that it can be accommodated between the upwardly extending upper portions 7 of the side walls 3 of a similar container stacked thereunder.

5 Den opadragende dimension af dét bundparti af containeren, der har en reduceret bredde, er tilnærmelsesvis lig med den opadragende dimension af sidevæggene 3's øvre dele 7 - for at give plads til tykkelsen af de i det følgende beskrevne containerlåg 17 under 10 stablingen af containere over hinanden. For at lette stablingen og adskillelsen af over hinanden stablede containere er sidevæggene 3's forskudte bundafsnit 11 fortrinsvis skråtstillet en smule udad fra bunden, som vist i fig. 1.The upward dimension of the bottom portion of the container having a reduced width is approximately equal to the upward dimension of the upper portions 7 of the side walls 3 - to accommodate the thickness of the container lid 17 described below in the stacking of containers over each other. For ease of stacking and separation of stacked containers, the offset bottom portion 11 of the sidewalls 3 is preferably inclined slightly outwardly from the bottom as shown in FIG. First

15 Gennem hver af containerens opadragende øvre si devægdele 7 strækker der sig to længdeslidser 13 over for to tilsvarende længdeslidser i den modstående sidevægdel 7. Disse længdeslidser 13 bibringer containeren evnen til at kunne løftes op fra toppen af en 20 stabel af sådanne containere, uden at der indvirkes forstyrrende på lignende nærliggende containere, som er anbragt under, ved hver side eller ved hver ende af containeren, der løftes.Through each of the container's upwardly extending upper side portions 7, two longitudinal slots 13 extend toward two corresponding longitudinal slots in the opposite side wall portion 7. These longitudinal slots 13 impart the ability of the container to be lifted from the top of a stack of such containers without interfering with similar nearby containers placed below, at each side or at each end of the container being lifted.

Der opnås en yderligere styrke langs de paral-25 leile øvre sidevægdele 7 ved anvendelse af en forstærkningsstang 15, som er fastgjort til modstående steder af sidevæggene 3's inderflader, såldes at dens overside kommer til at ligge i et plan parallelt med containerens bund i højde med topdelene 9 af endevæg-30 gene 5. Forstærkningsstangen 15 består fortrinsvis af et polyethylenrør, som ved hver ende er svejst til de nævnte modstående steder af sidevæggene 3's inderflader.Further strength is obtained along the parallel upper side wall portions 7 by using a reinforcing bar 15 which is attached to opposite locations by the inner surfaces of the side walls 3 so that its upper surface lies in a plane parallel to the bottom of the container with height. the reinforcing bar 15 preferably consists of a polyethylene tube welded at each end to said opposite locations by the inner surfaces of the side walls 3.

Containeren har et låg 17, der er dimensioneret 35 til tæt pasning mellem sidevæggene 3's opadragende øvre dele 7. Som det bedst fremgår af fig. 2, er låget 6The container has a lid 17 which is sized 35 to fit snugly between the upwardly extending upper portions 7 of the side walls 3. 2, the lid is 6

Låget 17 har endeflige 19, der strækker sig nedad over endevæggene 5 for snappasning med horisontale 5 riller 21 i endevæggene 5's ydersider. Låget 17 udgøres af en plade af polyethylen med høj densitet og med en tilstrækkelig tykkelse og styrke til at fastholde indholdet af fisk og is under fartøjets malning i søen. Låget 17 tjener desuden til at hindre forurening 10 af indholdet i containeren.17 at its ends supported by the top portions 9 of the end walls 5 while centrally supported by the reinforcing bar 15. The lid 17 has end flaps 19 extending downwardly over the end walls 5 for snap fit with horizontal 5 grooves 21 in the outer sides of the end walls 5. The lid 17 is made of a high density polyethylene plate of sufficient thickness and strength to retain the fish and ice content during the vessel's painting in the lake. The lid 17 additionally serves to prevent contamination 10 of the contents of the container.

Containeren har et drænhul 23, fig. 2, gennem én af endevæggene 5, for at vand, der hidrører fra smeltningen af is i containeren, kan drænes langs ydersiden af endevæggene 5 af derunder stablede containe-15 re. Drænhullet 23's boring er forsynet med gevind for at muliggøre indsætning af en med gevind forsynet dræntap 25. Smeltevand i containeren drænes indvendigt i retning mod drænhullet 23 via et arrangement af parallelle drænriller 27, som strækker sig i vertikal 20 retning langs endevæggene 5's inderflader og i langsgående retning langs bundvæggen 4's inderflade for at kommunikere med drænhullet 23.The container has a drain hole 23, fig. 2, through one of the end walls 5, so that water resulting from the melting of ice in the container can be drained along the outside of the end walls 5 of containers stacked thereunder. The drain hole 23 bore is threaded to allow insertion of a threaded drain pin 25. Melt water in the container is drained internally toward the drain hole 23 via an arrangement of parallel drain grooves 27 extending vertically 20 along the inner surfaces of the end walls 5 longitudinal direction along the inner surface of the bottom wall 4 to communicate with the drain hole 23.

Under anvendelsen af det i førnævnte DK patentansøgning nr. 3363/83 beskrevne udstyr vil der på for-25 skellige tidspunkter være et tomt rum mellem to stabler af containere. Endecontainerne i hver række af containere fastholdes mod en uønsket sideværts bevægelse ved, at de indgriber med opadragende T-profiler, som er nærmere beskrevet i nævnte DK patentansøgning. For at 30 hindre en forflytning af de indre containere i en række af containere nær ved det nævnte tomme rum som følge af fartøjets bevægelse i søen, fastgøres i det mindste containerne, som udgør hver række i det andet lag fra toppen af lastrummet, til hinanden ved hjælp af demon-35 terbare forbindelsesorganer, som kan udløses, når en sådan række af containere anbringes på fartøjets dækDuring the use of the equipment described in the aforementioned DK Patent Application No. 3363/83, at different times there will be an empty space between two stacks of containers. The end containers in each row of containers are held against an undesirable lateral movement by engaging with upwardly extending T-profiles, which are further described in said DK patent application. In order to prevent the movement of the inner containers in a series of containers near the said empty space as a result of the vessel's movement in the sea, at least the containers which make up each row in the second layer from the top of the cargo space are fixed to each other. by removable connecting means which can be released when such a series of containers are placed on the deck of the vessel
