Description

"Beholder av plaat".'"Container of plaat".'

Foreliggende oppfinnelse angår en tonne eller trommel fremstilt av termoplastisk materiale for bruk ombord i fiskefartoyer til nedlegging av fisk, hvis innhold er minst ti liter og som innbefatter minst en ring som gir den ekstra styrke. The present invention relates to a tonneau or drum made of thermoplastic material for use on board fishing vessels for laying down fish, the content of which is at least ten liters and which includes at least one ring which gives it extra strength.

Tonner av termoplastisk materiale med en separat fremstilt forsterkningsring er velkjente, idet ringen festes på tonneveggen med liming, sveising, eller andre passende metoder. Denne forsterkningsringen kan omfatte en utsikkende kant som kan anvendes til feste for kjettingkroker eller lignende når tonnen skal loftes. Tons of thermoplastic material with a separately manufactured reinforcing ring are well known, the ring being attached to the ton wall by gluing, welding, or other suitable methods. This reinforcement ring can include a protruding edge that can be used to attach chain hooks or the like when the ton is to be lifted.

Formålet med foreliggende oppfinnelse er å fremskaffe en tonne av ovenstående type som er mere formålstjenelig. I den hensikt foreslåes at tonnen forsynes med en innadrettet fordypning langs hele periferien og at forsterkningsringen monteres i denne fordypning. I en foretrukket utforelse har nevnte fordypning et tverrsnitt som en sirkelbue, og ringen har tilsvarende fasong, slik at dens ytterflate ligger i flukt med tonnens ytterside. Dette gjor det mulig å utnytte plassen optimalt når når tonnene stables ved siden av og oppå hverandre, idet ringene ikke krever ekstra plass. Det er også mindre risiko for skader. Ved å gi ringens tverrsnitt en avrundet utforming, kan det unngås at den skitnes til. Siden den ligger i flukt med tonneveggen, er det også mindre sjanse for at skitt legger seg bak kanten. The purpose of the present invention is to provide a tonne of the above type which is more useful. To that end, it is proposed that the barrel be provided with an inwardly directed recess along the entire periphery and that the reinforcement ring be mounted in this recess. In a preferred embodiment, said recess has a cross-section like a circular arc, and the ring has a corresponding shape, so that its outer surface lies flush with the outer side of the ton. This makes it possible to use the space optimally when the tonnes are stacked next to and on top of each other, as the rings do not require extra space. There is also less risk of injury. By giving the ring's cross-section a rounded design, it can be avoided that it gets dirty. Since it lies flush with the barrel wall, there is also less chance of dirt settling behind the edge.

I henhold til en annen utforelse av oppfinnelsen ligger nevnte fordypning i nærheten av begge endene på tonnen, slik at tonnens diameter mellom de to ringene og endene er noe mindre enn mellom ringene. According to another embodiment of the invention, said recess is located near both ends of the barrel, so that the diameter of the barrel between the two rings and the ends is somewhat smaller than between the rings.

For å gi en bedre forståelse av foreliggende oppfinnelse skal noen utforelser nå beskrives med henvisning til vedlagte tegninger, hvorav Fig. 1 viser delvis i tverrsnitt, delvis sett fra siden, en tonne i henhold til foreliggende oppfinnelse, og In order to provide a better understanding of the present invention, some embodiments will now be described with reference to the attached drawings, of which Fig. 1 shows partly in cross-section, partly seen from the side, a tonne according to the present invention, and

Fig. 2 viser visse detaljer av en annen utforelse.Fig. 2 shows certain details of another embodiment.

På fig. 1 er tonnen betegnet med 1, og omfatter en bunnseksjon 2, som via en avrundet seksjon 3 går over i den sylindriske tonneveggen 4, Via nok en avrundet seksjon 5 går denne over i en hals 6. Halsen har innstopte gjenger hvorpå kan skrus fast en kappe 7. Denne har en U-formet kant og en åpning 8 i midten. Et forsenket lokk 9 sitter mellom kappen og kanten på tonnen, og lokket har også en kant 10 som er U-formet. En pakning av elastisk materiale ligger inne i den U-formede fordypning. Undersiden av bunnen 2 er trukket noe tilbake i forhold til avrundet seksjon 3. In fig. 1, the barrel is denoted by 1, and comprises a bottom section 2, which via a rounded section 3 passes into the cylindrical barrel wall 4, Via yet another rounded section 5, this passes into a neck 6. The neck has recessed threads on which a cover 7. This has a U-shaped edge and an opening 8 in the middle. A recessed lid 9 sits between the jacket and the edge of the barrel, and the lid also has an edge 10 which is U-shaped. A gasket of elastic material lies inside the U-shaped recess. The underside of the base 2 is pulled back somewhat in relation to the rounded section 3.

Tonnen blir fremstilt på vanlig måte ved at der forst lages et ror ved ekstrudering av termoplast. Dette roret blir så til en tonne ved en blåseprosess i form, idet bunnen fremkommer ved at roret knipes sammen på riktig sted. Den sveisesom som derved fremkommer vil ligge i det området som avgrenses av seksjon 3 og stikker ut fra bunnen 2. Den formen som brukes til dette har to rygger med hovedsakelig sirkelformet tverrsnitt som gir to fordypninger eller spor 12 og 13, i tonneveggen. FoiSterknings-ringer med tilsvarende sirkelbuet tverrsnitt blir så montert i disse fordypningene med ytre diametre i flukt med den tonneveggen 4 som ligger mellom dem. Disse ringene 14 fyller ikke opp hele fordypningen 12 og 13, men gir plass for en svakt kileformet lomme 15 mellom tonneveggen og ringen 14. Dette gjor det mulig å feste loftekroker under ringene, for eksempel to L-formede kroker på en kjetting. Disse forsterkningsringene 14 kan presses i fordypningene, idet ringene og/eller tonnen varmes opp så mye at de ganske lett kan deformeres plastisk. The barrel is produced in the usual way by first making a rudder by extruding thermoplastic. This rudder is then turned into a tonne by a process of blowing it into shape, with the bottom appearing when the rudder is pinched together in the right place. The resulting weld will lie in the area delimited by section 3 and protrudes from the bottom 2. The mold used for this has two ridges with a mainly circular cross-section which give two recesses or grooves 12 and 13, in the tonneau wall. FoiStrengthening rings with a corresponding circular cross-section are then mounted in these recesses with outer diameters flush with the tonneau wall 4 which lies between them. These rings 14 do not fill up the entire recess 12 and 13, but provide space for a slightly wedge-shaped pocket 15 between the barrel wall and the ring 14. This makes it possible to attach ceiling hooks under the rings, for example two L-shaped hooks on a chain. These reinforcing rings 14 can be pressed into the recesses, the rings and/or the barrel being heated so much that they can be plastically deformed rather easily.

Som fig. 1 viser kan det anvendes en liten rygg eller kant 17 i fordypning 12 og 13, slik at når ringen er på plass vil denne kant 17 ligge i bunnen av lommen 15. Dette gir bedre feste for ringen 14. Kanten 17 kan utformes ved at tonneveggen trykkes utover, for eksempel når tonnen utformes ved nevnte blåseprosess. I henhold til en andre utforelse, vist nærmere på fig. 2, så ligger fordypning 12 innen.en del av tonnen som har en mindre diameter (ved 16) enn resten av tonneveggen 4. Det gjor montering av ringen enda lettere, uten at dens feste på tonnen blir svekket. Når tonnen loftes ved hjelp av nevnte type kroker så vil faktisk hele påkjenningen på tonnen være rettet langs-etter tonneveggen 4. As fig. 1 shows, a small ridge or edge 17 can be used in recesses 12 and 13, so that when the ring is in place, this edge 17 will lie at the bottom of the pocket 15. This provides a better attachment for the ring 14. The edge 17 can be designed by the tonneau wall is pressed outwards, for example when the barrel is shaped by the aforementioned blowing process. According to a second embodiment, shown in more detail in fig. 2, then recess 12 lies within a part of the barrel which has a smaller diameter (at 16) than the rest of the barrel wall 4. This makes mounting the ring even easier, without its attachment to the barrel being weakened. When the tonneau is lifted using the aforementioned type of hooks, the entire stress on the tonneau will actually be directed along the tonneau wall 4.
