BESCHRIJVINGDESCRIPTION

Een voorgevouwen verlijmd karton, papier of kunststof met een laag van aluminium of ander metaal waarin een drager van voedingsmiddelen kan worden geplaatst zodat deze opgewarmd kan worden in de magnetron.A pre-folded glued cardboard, paper or plastic with a layer of aluminum or other metal in which a food carrier can be placed so that it can be heated in the microwave.

De uitvinding heeft betrekking op het gecontroleerd verwarmen van voedingsmiddelen in een magnetron. De uitvinding betreft een onafhankelijke drager van karton met daarin verwerkt een laag aluminium die op bepaalde plaatsen de directe straling op de inhoud tegen gaat.The invention relates to the controlled heating of foods in a microwave. The invention relates to an independent carrier of cardboard with a layer of aluminum incorporated therein that prevents direct radiation on the contents at certain places.

Houders van voedingsmiddelen, zoals schalen en bakjes, bevatten een of meerdere compartimenten. In deze houders worden maaltijden verpakt waarbij de ingrediënten in een of meerdere compartimenten zitten, bijv. vlees afzonderlijk van aardappel en/ of groente maaltijdcomponent.Food containers, such as trays and trays, contain one or more compartments. Meals are packed in these containers with the ingredients in one or more compartments, eg meat separate from potato and / or vegetable meal component.

In een magnetron worden voedingsmiddelen opgewarmd doordat watermoleculen die aanwezig zijn in het voedsel, door straling in beweging worden gebracht. In de magnetronmaaltijden of in andere in magnetron te bereiden voedingsmiddelen worden alle ingrediënten aan dezelfde straling blootgesteld. Het is daarom niet mogelijk om verschillende ingrediënten op verschillende temperaturen op te warmen. Een biefstuk waarin de binnenzijde rauw dient te blijven zal met directe magnetronstraling snel garen doordat de magnetronstraling het eetbare materiaal tot in de kern verwarmt. Bovendien verdwijnt de malsheid van de biefstuk door invloed van de straling. Daarnaast is een magnetronmaaltijd gedurende de bereidingstijd in een moderne magnetron onderhevig aan eenzelfde hoeveelheid straling. Dat wil zeggen dat alle ingrediënten dezelfde hoeveelheid straling krijgen. Echter, het ene product heeft een andere bereidingstijd dan het andere product, zodat de tijd in de magnetron afgestemd wordt op het meest langzaam garende component. Het gevolg hiervan is dat de sneller garende producten teveel energie krijgen waardoor deze te gaar worden.In a microwave, foods are heated because water molecules that are present in the food are set in motion by radiation. In the microwave meals or in other microwave-ready foods, all ingredients are exposed to the same radiation. It is therefore not possible to heat different ingredients at different temperatures. A steak in which the inside must remain raw will cook quickly with direct microwave radiation because the microwave radiation heats the edible material to the core. Moreover, the tenderness of the steak disappears due to the influence of the radiation. In addition, a microwave meal during the preparation time in a modern microwave oven is subject to the same amount of radiation. This means that all ingredients receive the same amount of radiation. However, one product has a different preparation time than the other product, so that the time in the microwave is adjusted to the slowest-cooking component. The consequence of this is that the faster-yielding products receive too much energy, which causes them to overcook.

De uitvinding heeft betrekking op het indirect verwarmen van voedingsmiddelen of een deel van de voedingsmiddelen in een magnetron schaal met een of meerdere compartimenten zonder dat de structuur van het voedsel wordt aangetast. Door middel van een vouwconstructie van karton worden een of meerdere compartimenten van een magnetronmaaltijd afgeschermd zodat deze beschermde compartimenten aan minder straling onderhevig zijn. Het afschermen wordt bereikt door gebruik te maken van het natuurkundige principe, dat de magnetron straling niet door metaal kan doordringen maar weerkaatst wordt. De constructie is zo gemaakt dat er minder straling direct op het etenswaar terecht komt. Het voedingsmiddel wordt gecontroleerd verwarmd door ofwel direct de in de atmosfeer in de gesloten schaal aanwezige kopruimte boven de voedingsmiddelen te verwarmen of voorkomen dat er teveel straling bij de te verwarmen voedingsmiddelen terecht komt.The invention relates to the indirect heating of food or a part of the food in a microwave dish with one or more compartments without the structure of the food being affected. One or more compartments of a microwave meal are screened off by means of a folding construction made of cardboard, so that these protected compartments are subject to less radiation. Shielding is achieved by using the physical principle that the microwave radiation cannot penetrate metal but is reflected. The construction is made in such a way that less radiation ends up directly on the food. The foodstuff is heated in a controlled manner by either directly heating the headspace in the atmosphere in the closed dish above the foodstuffs or preventing too much radiation from ending up with the foodstuffs to be heated.

Er wordt een afscherming gemaakt door een onafhankelijke vouwconstructie van karton te maken waarbij het materiaal voorzien is van een aluminium laag tussen twee of meerdere lagen in. De vouwconstructie wordt gestanst vanuit een plaat of rol en vervolgens in elkaar gezet door verlijming waarbij de te verlijmen klepjes aan de binnenzijde worden geplaatst. De vouwconstructie kan bijvoorbeeld een 4-punts verlijmd doosje zijn die om een compartiment van de schaal kan worden geschoven.A shield is made by making an independent folding construction from cardboard, wherein the material is provided with an aluminum layer between two or more layers. The folding structure is punched from a plate or roll and then assembled by gluing, whereby the flaps to be glued are placed on the inside. The folding construction can for instance be a 4-point glued box that can be slid around a compartment of the tray.

Een uitstekende flap of klep sluit de schaal aan de bovenzijde bijna geheel af. De bovenklep is in alle dimensies 5 mm kleiner dan de sealrand aan de bovenzijde van de houder, zodat de sealrand voorkomt dat het karton met daarin het aluminium dat deze in aanraking komt met de metalen wand van de magnetron. Een andere mogelijkheid is om het karton aan de bovenzijde alleen op de hoeken 5 mm binnen de sealrand te laten vallen. De klep wordt door middel van verlijming bevestigd aan de drager. Een andere mogelijkheid is om deze via een etiket te verbinden met het deel aan de onderzijde.A protruding flap or flap almost completely closes the bowl on top. The top flap is 5 mm smaller in all dimensions than the seal edge on the top of the holder, so that the seal edge prevents the cardboard with the aluminum in it from coming into contact with the metal wall of the microwave. Another possibility is to let the cardboard on the top side fall only 5 mm within the seal edge at the corners. The valve is attached to the support by gluing. Another possibility is to connect this via a label to the lower part.

Het deel aan de onderzijde van de verlijmde vouwconstructie schermt het voedsel in horizontale richting geheel af van magnetronstraling. De kopruimte boven het voedsel wordt niet afgeschermd waardoor straling in de drager kan doordringen. In de zijde met klep is een opening gecreeerd waardoor tevens straling kan doordringen in de kopruimte van de houder.The part on the underside of the glued folding construction completely shields the food in the horizontal direction from microwave radiation. The headspace above the food is not shielded so that radiation can penetrate into the carrier. An opening has been created in the side with flap through which radiation can also penetrate into the head space of the container.

Alle hoeken van de stans van karton zijn afgerond met een diameter van minimaal 5 mm zodat er geen ophoping van energie kan plaatsvinden om vonken of kortsluiting te creeren gedurende de opwarming.All corners of the cardboard punch are rounded with a diameter of at least 5 mm so that no energy accumulation can take place to create sparks or short circuits during heating.

De uitvinding kan zowel aan de binnenzijde als buitenzijde bedrukt worden.The invention can be printed on both the inside and outside.

De uitvinding heeft vele toepassingen, slechts als voorbeeld wordt de maaltijd uit meerdere componenten genoemd. Een ander voorbeeld voor de toepassing is bijvoorbeeld het bereiden van een saus op basis van boter of het opwarmen van babymelk, of babymaaltijd.The invention has many uses, only as an example is the multi-component meal mentioned. Another example for the application is, for example, preparing a butter-based sauce or heating up baby milk, or baby meal.

De uitvinding zal hieronder nader worden uiteengezet aan de hand van een in figuren weergegeven uitvoeringsvoorbeeld van het systeem volgens de uitvinding.The invention will be explained in more detail below with reference to an exemplary embodiment of the system according to the invention shown in figures.
