Det er kendt at transportere friske halvfabrikata, såsom fisk, sammen med is i kasser, som i stor udstrækning er fremstillet af ekspanderet polystyren. Sådanne kasser har normalt en vægtykkelse på imellem 15 og 30 mm, og bunden er som regel noget tyndere end væggene og forsynet med forskellige forstærkninger og mønstre på undersiden, som blandt andet har til hensigt at virke som styr, når kasserne stables.It is known to transport fresh semi-finished products, such as fish, together with ice in boxes, which are largely made of expanded polystyrene. Such boxes usually have a wall thickness of between 15 and 30 mm, and the bottom is usually somewhat thinner than the walls and provided with various reinforcements and patterns on the underside, which, among other things, intend to act as a guide when the boxes are stacked.

Kasserne er typisk beregnet til transport over længere af-15 stande og rummer som regel 10 til 20 kg fisk plus den is, der er nødvendig for at nedkøle og holde fisken frisk under transporten. Til de forskellige transportkasser findes der som regel et låg, som placeres på den øverste transportkasse i en stabel. Det kan imidlertid også forekomme, at hver trans-20 portkasse er forsynet med låg.The crates are typically intended for transport over longer distances and usually contain 10 to 20 kg of fish plus the ice needed to cool and keep the fish fresh during transport. For the various transport boxes, there is usually a lid, which is placed on the top transport box in a stack. However, it may also happen that each transport case is provided with a lid.

Nedkølingen af den friske fisk i transportkasserne foregår ved en temperaturudligning mellem fisken og isen sammen med en luftcirkulation. Hvis der ønskes en hurtig og ensartet 25 temperaturudligning, gælder det om at få en stor kontaktflade mellem fisken og den kolde luft fra isen. Når den friske fisk lægges i transportkasserne, har fisken imidlertid tilbøjelighed til hurtigt at synke sammen, så der dannes en form for kage, der slutter tæt mod bunden og siderne af transport-30 kassen. Denne tilbøjelighed forstærkes yderligere af, at isen lægges oven på fisken. Denne form for nedisning bevirker, at den kolde luft fra isen i praksis kun kan komme i kontakt med den øverste overflade af "fiskekagen" og således ikke med de fire sider og undersiden.The cooling of the fresh fish in the transport boxes takes place by a temperature equalization between the fish and the ice, together with an air circulation. If a quick and uniform temperature equalization is desired, it is important to have a large contact surface between the fish and the cold air from the ice. However, when the fresh fish is placed in the transport boxes, the fish tends to sink quickly to form a form of cake that ends close to the bottom and sides of the transport box. This tendency is further enhanced by the ice being laid on top of the fish. This type of icing means that in practice the cold air from the ice can only come into contact with the upper surface of the "fish cake" and thus not with the four sides and the underside.

Formålet med opfindelsen er at tilvejebringe en kasse, som forbedrer muligheden for temperaturudligning imellem fisk 35 2The object of the invention is to provide a box which improves the possibility of temperature equalization between fish 35 2

og is ved luftcirkulation.and ice by air circulation.

5 Dette opnås ifølge opfindelsen ved, at den indledningsvis nævnte kasse er ejendommelig ved, at der i sidevæggene på disses indvendige sider findes indad åbne i brugsstillingen lodrette cirkulationskanaler, og at der på den indvendige side af bunden findes diagonalt forløbende og/eller i hoved-sagen langsgående og tværgående kanaler, som står i forbindelse med de lodrette cirkulationskanaler i sidevæggene.This is achieved according to the invention in that the box mentioned above is characterized in that in the side walls on their inner sides there are inwardly open in the position of use vertical circulation channels and that on the inner side of the bottom there are diagonally extending and / or in the main. the case longitudinal and transverse channels, which are connected to the vertical circulation channels in the sidewalls.

Herved opnås, at der tilvejebringes en kasse, hvori der kan foregå luftcirkulation frit via kanalerne i sidevæggene og 15 bunden rundt langs alle sider af fiskekagen eller laget af fisk, hvorved sikres, at den kolde lufts kontaktflade med den friske fisk forøges væsentligt, hvilket sikrer en forholdsvis hurtig og jævn temperaturudligning mellem fisken og isen.This provides a box in which air circulation can take place freely via the channels in the sidewalls and the bottom around all sides of the fishcake or layer of fish, thereby ensuring that the cold air's contact surface with the fresh fish is substantially increased, which ensures a relatively fast and even temperature equalization between the fish and the ice.

Derudover kan ifølge opfindelsen bundens øvre overflade i . brugsstillingen have en stigning fra bundens midte i retning imod bundens sider, hvorved opnås større sikkerhed for, at den varme luft under kassens indhold tvinges mod de lodrette 25 cirkulationskanaler i sidevæggene og giver plads for en effektiv køling.In addition, according to the invention, the upper surface of the bottom can be. the position of use having a rise from the center of the bottom towards the sides of the bottom, thereby providing greater assurance that the hot air below the contents of the box is forced against the vertical 25 circulation ducts in the side walls and allows for efficient cooling.

De diagonalt forløbende og/eller langsgående og tværgående kanaler kan ifølge opfindelsen være således tildannet, at 30 de afgrænser knopper eller fremspring med cirkulært tværsnit og plane øvre overflader, hvorved opnås en særlig hensigtsmæssig udførelsesform for opfindelsen.According to the invention, the diagonally extending and / or longitudinal and transverse channels may be formed such that they define knobs or projections of circular cross-section and flat upper surfaces, thereby providing a particularly convenient embodiment of the invention.

Endelig kan ifølge opfindelsen bundens overflade være afgrænset af langs kassens sidevægge forløbende fordybninger, scan danner forbindelsen imellem de lodrette cirkulationskanaler i sidevæggene og de diagonalt forløbende og/eller langsgåen-5 de og tværgående kanaler i bunden. Herved opnås, at alle ka naler står direkte i forbindelse med de lodrette cirkulationskanaler ved deres yderste ender ved sidevæggene.Finally, according to the invention, the bottom surface of the bottom may be bounded by recesses extending along the side walls of the box, scan forming the connection between the vertical circulation channels in the side walls and the diagonally extending and / or longitudinal and transverse channels in the bottom. This ensures that all channels are directly connected to the vertical circulation channels at their outer ends at the side walls.

' Opfindelsen forklares nedenfor under henvisning til tegningen, 10 hvor fig. 1 viser skematisk en foretrukken udførelsesform for en fiskekasse ifølge opfindelsen, set i perspektiv, 15 fig. 2 viser et lodret snit igennem en del af den i fig. 1 viste kasse, set i større målforhold, og med de viste dele afbildet mere detaljeret end i fig. 1, og fig. 3 den i fig. 2 viste afbildning, set ovenfra.The invention is explained below with reference to the drawing, in which fig. 1 is a diagrammatic perspective view of a preferred embodiment of a fishing box according to the invention; FIG. 2 is a vertical section through a portion of FIG. 1 in larger dimensions and with the parts shown depicted in more detail than in FIG. 1, and FIG. 3 shows the one shown in FIG. 2 is a top view.

Den i fig. 1-3 viste kasse, som med hensyn til udvendige kendte forstærkningsribber og lignende træk er afbildet yderst forenklet, omfatter en bund 1 og herfra opadragende sidevægge 2, . som er indbyrdes forbundet ved :hjørnerne.The FIG. 1-3, which with respect to exterior known reinforcing ribs and similar features are depicted extremely simplified, comprises a bottom 1 and upwardly extending side walls 2 therefrom. which are interconnected by: the vertices.

25 I sidevæggene er der med passende mellemrum tildannet lodret te cirkulationskanaler 6 på sidevæggenes indvendige sider.In the side walls, vertical tea circulation ducts 6 are formed at appropriate intervals on the inner sides of the side walls.

Disse cirkulationskanaler 6 strækker sig ned til overgangen imellem sidevæggene 2 og bunden 1, hvor der findes en fordybning 7, som strækker sig hele vejen rundt langs sidevæg-30 gene, og som står i forbindelse med et net af kanaler 8 i bunden. Disse kanaler 8 har i den viste udførelsesform en sådan form, at bunden har et vaflet udseende, hvilket vil sige, at bunden overalt består af opadragende knopper 9, som hver har et cirkulært tværsnit og en øvre plan overflade 10.These circulation channels 6 extend down to the transition between the side walls 2 and the bottom 1, where there is a recess 7 which extends all the way around the side walls and which is connected to a network of channels 8 at the bottom. These channels 8, in the embodiment shown, have such a shape that the bottom has a wafer appearance, that is, the bottom everywhere consists of upwardly projecting buds 9, each having a circular cross-section and an upper planar surface 10.

35 Som det tydeligst fremgår af fig. 2, er bunden af kanalerne tildannet med et fald i retning fra bundens midte ud imod bundens sider. Dette fald er antydet ved dimensionen a. Til-35 As can be seen most clearly in FIG. 2, the bottom of the channels is formed with a decrease in direction from the bottom of the bottom towards the sides of the bottom. This decrease is indicated by the dimension a.
