Varmeisolerende beholdere av kunststoff. Heat-insulating plastic containers.

Oppfinnelsen vedrører en todelt varmeisolerende beholder som består av en tosjikts skål av kunststoff og et lukkeblad som dekker over åpningen. The invention relates to a two-part heat-insulating container which consists of a two-layer plastic bowl and a closing leaf which covers the opening.

Til grunn for oppfinnelsen ligger den- oppgave å tilveiebringe en varmeisolerende beholder av kunststoff som er lett å fremstille og hvis lukkeblad såvel er varmeisolerende som også tilstrekkelig bestandig overfor mekaniske innvirk-ninger utenifra. The invention is based on the task of providing a heat-insulating container made of plastic which is easy to manufacture and whose closing leaf is both heat-insulating and also sufficiently resistant to external mechanical influences.

Oppgaven som ligger til grunn for oppfinnelsen løses ved en varmeisolerende beholder, bestående av en tosjikts underdel av kunststoff og et fleresjikts kunststofflokk som lukker underdelens åpning, idet beholderen erkarakterisert vedat den består av en skål av et laminat oppbygget av et porefritt sjikt av termoplastisk kunststoff og et. cellulært strukturert tilstrekkelig formstabilt sjikt av termoplastisk kunststoff, idet skålåpningen' lukkes med et lukkeblad av et flerelags flatt laminat som består av minst et skumstrukturert lag av termoplastisk kunststoff og et porefritt lag av termoplastisk kunststoff og idet skålen i området for skålmunningskanten "overside er forbundet fast med lukkebladet ved hjelp av forsegling. The task underlying the invention is solved by a heat-insulating container, consisting of a two-layer lower part made of plastic and a multi-layer plastic flock that closes the opening of the lower part, the container being characterized by the fact that it consists of a bowl made of a laminate made up of a pore-free layer of thermoplastic plastic and a. cellular structured sufficiently stable layer of thermoplastic plastic, the bowl opening' being closed with a closing blade of a multi-layered flat laminate consisting of at least one foam-structured layer of thermoplastic plastic and a pore-free layer of thermoplastic plastic and the bowl in the area of the bowl mouth edge' being firmly connected with the closing leaf by means of sealing.

Det er derved med "skål" å.forstå et hullegeme som består av ert bunndel og fra denne oppadstrekkende side-vegger. Overkanten av denne skålomkretsvegg danner og om-grenser skålmunningen. By "bowl" is therefore meant a hollow body consisting of a bottom part and from this side walls extending upwards. The upper edge of this bowl perimeter wall forms and borders the bowl mouth.

Det skumstrukturerte, tilstrekkelige egenstive sjikt av skålen består fortrinnsvis av polystyren, den porefrie folie er fortrinnsvis, slagseig og består spesielt fordelaktig av polystyren. The foam-structured, sufficiently rigid layer of the bowl preferably consists of polystyrene, the pore-free foil is preferably impact-resistant and particularly advantageously consists of polystyrene.

Lukkebladet består av et flerelags kunststofflaminat, idet de.t første lag består av porefri kunststoff olie og det annet av fast kunststoffskum. Eventuelt er det mellom første og annet lag anordnet et tredje lag i form av en sammenlignet til første og annet lag tynt, ikke selvbærende film som bevirker sammenklebning av de to nevnte lag. The shutter blade consists of a multi-layer plastic laminate, with the first layer consisting of pore-free plastic oil and the second of solid plastic foam. Optionally, a third layer is arranged between the first and second layers in the form of a thin, non-self-supporting film compared to the first and second layers, which causes the two aforementioned layers to stick together.

De porefrie folieblad av lukkebladet består fortrinnsvis av molekylært orientert polytereftalatfolie og det skumstrukturerte 'lag av polystyren. The pore-free foil leaves of the closing leaf preferably consist of molecularly oriented polyterephthalate foil and the foam-structured layer of polystyrene.

I denne utførelse er det mellom.disse lag anordnet et tredje lag i form av en ikke selvbærende klebefilm, fortrinnsvis en slik på basis av polyuretan. En beholder med et lukkeblad av den foretrukkede oppbygning er foretrukket. In this embodiment, a third layer is arranged between these layers in the form of a non-self-supporting adhesive film, preferably one based on polyurethane. A container with a closure blade of the preferred construction is preferred.

Skålen har ved munningen av omkretsveggen én rundtløpende, utad utragende, flenslignende munningskant. At the mouth of the peripheral wall, the bowl has one circumferential, outwardly projecting, flange-like mouth edge.

Formatet av lukkebladet er dimensjonert såledesThe format of the closing leaf is dimensioned as follows

at det dekker åpningen av skålen samt overflaten av munningskanten. that it covers the opening of the bowl as well as the surface of the mouth rim.

En spesielt foretrukket beholder består av enA particularly preferred container consists of a

skål som består av et sjikt av skumpolystyren med en m 2-vekt i området mellom 150 og 250 g og en slagfast porefri polystyrenfolie av en tykkelse i området mellom 150 og 250^u. bowl consisting of a layer of foam polystyrene with a m 2 weight in the range between 150 and 250 g and an impact-resistant non-porous polystyrene foil of a thickness in the range between 150 and 250 µm.

Lukkebladet av den foretrukne beholder bestårThe closure leaf of the preferred container consists of

av et skumpolystyrensjikt av en tykkelse i området mellom 3 ogof a foamed polystyrene layer of a thickness in the range between 3 and

k mm og en porefri, molekylorientert folie av polyetylen-tereftalat av en tykkelse i området mellom 8 til 20^u, fortrinnsvis av en tykkelse på 12^u, idet det mellom de to nevnte lag er anordnet en i forhold til tykkelsen av den porefrie film tynn klebefilm av polyuretan.. I en spesielt foretrukket utførelsesform består beholderen av en skål, hvor såvel inn-siden som også oversiden av munningskanten består av porefri folie av slagseig polystyren, mens skålens ytterside og under-side av munningskanten er dannet av et .skumstrukturelt sjikt av- polystyren. Lukkebladet av den foretrukne beholder består av en cellulær, strukturell folie av polystyren med en porefri, strekkorientert polyesterfolie og et mellom de to folier anordnet tynt, ikke selvbærende klebefilm av polyuretan. Lukkebladet er forbundet således med skålen at den cellulært struk-turerte folie grenser umiddelbart til oversiden av skålmunningskanten og er forbundet med denne ved forsegling. k mm and a pore-free, molecularly oriented foil of polyethylene terephthalate of a thickness in the range between 8 to 20 µm, preferably of a thickness of 12 µm, with a relative to the thickness of the pore-free layer being arranged between the two mentioned layers film thin adhesive film of polyurethane.. In a particularly preferred embodiment, the container consists of a bowl, where both the inside and the top of the mouth edge consist of non-porous foil of impact-resistant polystyrene, while the outer side of the bowl and the underside of the mouth edge are formed by a . foam structural layer of polystyrene. The closing leaf of the preferred container consists of a cellular, structural foil of polystyrene with a pore-free, stretch-oriented polyester foil and a thin, non-self-supporting adhesive film of polyurethane arranged between the two foils. The closing blade is connected to the bowl in such a way that the cellular structured foil borders immediately on the upper side of the bowl mouth edge and is connected to this by sealing.

Istedenfor forsegling kan det også sveises,Instead of sealing, it can also be welded,

idet virkningen med hensyn til forbindelsens fasthet er lik. as the effect with regard to the firmness of the connection is the same.

Skålen samt lokket av beholderen ifølge oppfinnelsen har gode isoleringsegenskaper, forbindelsen mellom lukkeblad og skål-kant på den ene side tilstrekkelig fast, på den annen side lar lukkebladet seg tilstrekkelig lett rive av fra skålens flenskant uten at derved lukkebladets skumsjikt ødelegges. Fullgods inneholdt i beholderen kan oppvarmes i denne når man utsetter beholderen for virkning av mikrobølger, fortrinnsvis i en mikrobølgeovn. The bowl as well as the lid of the container according to the invention have good insulating properties, the connection between the closing leaf and the bowl edge is on the one hand sufficiently firm, on the other hand the closing leaf can be sufficiently easily torn off from the flange edge of the bowl without thereby destroying the closing leaf's foam layer. Whole goods contained in the container can be heated in it when the container is exposed to the action of microwaves, preferably in a microwave oven.

Oppfinnelsen forklares nærmere på tegningen som viser en beholder i tverrsnitt, idet lagenes veggtykkelse er gjengitt i overdreven målestokk. The invention is explained in more detail in the drawing which shows a container in cross-section, the wall thickness of the layers being reproduced on an exaggerated scale.

Den skålformede del av beholderen består av et laminat av et skumstrukturert sjikt av polystyren 1 og en porefri folie av polystyren 2. Lukkebladet som dekker skålens åpning er et laminat av en skumstrukturert -poly styrenf olie 11 og en folie av molekylært orientert polyester 4, idet det mellom begge folier er anordnet en klebefilm 3 av polyuretan. Lukkebladet ligger på oversiden av skålens munningskant og er forbundet med denne ved forsegling. The bowl-shaped part of the container consists of a laminate of a foam-structured layer of polystyrene 1 and a pore-free foil of polystyrene 2. The closing blade that covers the opening of the bowl is a laminate of a foam-structured polystyrene foil 11 and a foil of molecularly oriented polyester 4, an adhesive film 3 of polyurethane is arranged between both foils. The closing blade is located on the upper side of the mouth edge of the bowl and is connected to this by sealing.

Det er en spesiell fordel ved beholderen ifølge oppfinnelsen at lukkebladet på den ene side virker varmeisolerende, på den andre side imidlertid er meget bestandig overfor mekanisk innvirkning. It is a particular advantage of the container according to the invention that the closing leaf acts as a heat insulator on the one hand, but on the other hand is very resistant to mechanical impact.

Beholderen fremstilles eksempelvis ved at man danner skålen av et flateaktig kunststofflaminat av et cellulært sjikt av termoplastisk kunststoff, eksempelvis fra en polystyrenskumfolie og en porefri folie av termoplastisk kunststoff, eksempelvis en slagseig polystyrenfolie på- i og for seg The container is produced, for example, by forming the bowl from a flat plastic laminate of a cellular layer of thermoplastic plastic, for example from a polystyrene foam foil and a pore-free foil of thermoplastic plastic, for example an impact-resistant polystyrene foil on its own
