(54) Plastbakke til understøtning af fødevarer.(54) Plastic tray for food support.

Opfindelsen angår en bakke af plast til understøtning af fødevarer og med en af opstående sidevægge omgivet bund, der er udformet med ribber med mellemliggende åbne felter, idet ribberne har en sådan højde over bakkens bund, at der mellem undersiden af varer, som anbringes i bakken, og dennes bund fremkommer et luftmellemrura.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a plastic tray for food support and having a bottom surrounded by raised sidewalls, formed with ribs with intermediate open fields, the ribs having a height above the bottom of the tray that between the underside of the articles placed in the tray , and its bottom appears an air midrura.

Plastbakker af ovennævnte art anvendes i stort omfang til emballering af kødvarer og navnlig kødskiver, som er beregnet til udstil-J] ling i butikkernes kølediske. Ved emballeringen af sådanne kødskiver >· anbringes disse på en plastbakke, og bakken og kødskiverne indeslut- tes i en folie, fortrinsvis plastfolie, hvorpå emballagen tillukkes, & fortrinsvis ved varmeforsegling. Hvis kødskiverne er blevet udskåret ^ o r- ved en temperatur på 6 C eller derunder og de derpå opbevares ved så- danne lave temperaturer, er udsivningen af kødsaft fra kødet minimal.Plastic trays of the aforementioned type are widely used for packaging meat products and in particular meat slices, which are intended for display in stores' refrigeration counters. In the packaging of such meat slices, they are placed on a plastic tray and the tray and meat slices are enclosed in a foil, preferably plastic foil, on which the packaging is sealed, & preferably by heat sealing. If the meat slices have been cut out at a temperature of 6 ° C or less and then stored at such low temperatures, the leakage of meat juice from the meat is minimal.

a 2 145077 I praksis er det imidlertid vanskeligt at forhindre, at kødets temperatur under udskæringen og emballeringen stiger til over 6°C.a 2 145077 In practice, however, it is difficult to prevent the temperature of the meat during cutting and packaging from rising above 6 ° C.

Som følge heraf har man måttet akceptere, at der, allerede inden forbrugerne modtager kødvarer, der er emballeret som beskrevet, forekommer en vis mængde kødsaft i bunden af plastbakkerne.As a result, it has been accepted that, even before consumers receive meat products packaged as described, a certain amount of meat juice occurs at the bottom of the plastic trays.

Ydermere vil temperaturen af kødvarer, som er blevet udskåret, emballeret og opbevaret ved 6°C eller derunder, normalt stige til over 6°C under forbrugernes hjemtransport af varerne.Furthermore, the temperature of meat products that have been cut, packaged and stored at 6 ° C or below will normally rise to above 6 ° C during consumer home transport of the goods.

Udover, at udsivet kødsaft giver de emballerede varer et forringet udseende, har kødsaften den uheldige virkning, at de ved en varme-forsegling dannede svejsesømme bliver utætte, hvorved kødsaft kan sive ud af emballagen.In addition to the fact that the exposed meat juice gives the packaged goods a deteriorated appearance, the meat juice has the unfortunate effect that the weld seams formed by a heat seal become leaky, whereby the juice can leak out of the packaging.

Formålet med opfindelsen er at tilvejebringe en plastbakke af den i indledningen angivne art, hvormed udsivet kødsaft forhindres i at trænge ud af bakken og forringe udseendet af fødevarer, som er anbragt i bakken.The object of the invention is to provide a plastic tray of the kind indicated in the introduction, by which the exposed meat juice is prevented from exiting the tray and deteriorating the appearance of food placed in the tray.

Dette formål opnås med plastbakken ifølge opfindelsen, hvilken plastbakke er ejendommelig ved, at den har et midterfelt, i hvilket der er anbragt et lag væskeabsorberende materiale, og at ribberne er således udformede, at væske langs bakkens bund uhindret kan strømme fra de øvrige felter til midterfeltet.This object is achieved with the plastic tray according to the invention, which is characterized in that it has a middle field in which a layer of liquid absorbing material is arranged and the ribs are designed so that liquid along the bottom of the tray can flow freely from the other fields to middle field.

Ved at tilvejebringe et midterfelt med et lag væskeabsorberende materiale, hvortil der kan strømme væske fra de øvrige felter, i en plastbakke med ribber, der holder fødevaren hævet over bakkens bund, bliver eventuelt udsivende kødsaft hurtigt opsuget i det væskeabsorberende materiale, hvori den fastholdes, idet det absorberende mate— riale er beskyttet af ribberne mod sådanne trykpåvirkninger fra fødevaren, som ellers ville kunne fremkalde en udpresning af den absorberede væske.By providing a middle field with a layer of liquid-absorbing material to which liquid may flow from the other fields, in a plastic tray with ribs holding the food raised above the bottom of the tray, any leaking meat juice is rapidly absorbed into the liquid-absorbing material in which it is held. the absorbent material being protected by the ribs against such pressure effects from the food which would otherwise cause a compression of the absorbed liquid.

Da det væskeabsorberende materiale ikke behøver at komme i kontakt med fødevaren, vil materialet heller ikke følge med, når varen udtages af bakken.Since the liquid-absorbing material does not need to come into contact with the food, the material will also not follow when the product is removed from the tray.

Den udtagne vare kan derfor umiddelbart underkastes tilberedning.The product taken out can therefore immediately be subjected to preparation.

Der kendes plastbakker af formstofskum, hvis bund er forsynet med et prægemønster og hvortil der på et begrænset område er fastklæbet et stykke væskeabsorberende arkformet materiale. Fødevarer, der anbringes i sådanne bakker, vil således være i direkte kontakt med det væske-absorberende materiale, hvilket medfører, at opsuget kødsaft let ud- 3 145077 presses og at dele af materialet følger med, når varerne udtages af bakken.There are known plastic trays of plastic foam, the bottom of which is provided with an embossing pattern and to which, in a limited area, a piece of liquid-absorbing sheet-shaped material is adhered. Thus, foods placed in such trays will be in direct contact with the liquid-absorbing material, which causes aspirated meat juices to be readily squeezed and portions of the material accompany as the products are removed from the tray.

For at undgå, at der ved anvendelse af plastbakken ifølge opfindelsen ved tilfældig kontakt mellem den heri anbragte vare og fladen af væskeabsorberende materiale sker en fastklæbning af sidstnævnte til fødevaren, kan lagets overside ifølge opfindelsen fortrinsvis være dækket af en folie eller en plade af et væskeuigennemtrængeligt materiale, f.eks. plast.In order to avoid the adhesion of the latter to the food, by using the plastic tray according to the invention by accidental contact between the product placed therein and the surface of the liquid, the top surface of the invention may preferably be covered by a film or a plate of a liquid impervious material, e.g. plastic.

Eksempelvis kan laget af væskeabsorberende materiale være lamineret med en tynd plastfolie.For example, the layer of liquid absorbing material may be laminated with a thin plastic film.

Ved anvendelse af en uigennemsigtig folie eller plade kan der opnås en fuldstændig afskærmning af det væskeabsorberende materiale, således at forbrugeren forskånes for at se det i visse henseender uæstetiske kødsaftholdige materiale.By using an opaque film or plate, a complete shielding of the liquid-absorbing material can be obtained so that the consumer is spared to see the unesthetic meat-containing material in some respects.

Hvis man ønsker at sikre, at det væskeabsorberende materiale fastholdes i midterfeltet, uanset om bakken stilles på højkant eller vendes på hovedet, kan der anvendes en plastbakke, hvor de til midterfeltet grænsende ribber er forsynet med låseorganer til fastholdelse af plastpladen i den ønskede stilling.If it is desired to ensure that the liquid-absorbing material is retained in the middle panel, whether the tray is raised or turned upside down, a plastic tray may be used, where the ribs adjacent to the middle panel are provided with locking means for holding the plastic plate in the desired position.

Det væskeabsorberende materiale er f.eks. et stærkt sugende cellulosemasse. Ifølge opfindelsen kan laget være et cellulosefiber-lag, som er fremstillet ved en tørproces, idet et sådant materiale har en større absorptionsevne end et tilsvarende lag fremstillet ved en vådproces.The liquid absorbing material is e.g. a highly absorbent cellulose mass. According to the invention, the layer may be a cellulose fiber layer made by a dry process, such a material having a greater absorbency than a corresponding layer made by a wet process.

Ved at variere midterfeltets størrelse, tykkelsen af laget af væskeabsorberende materiale (og evt. ribbernes højde over bakkens bund) kan den samlede væskeabsorptionskapacitet reguleres på en sådan måde, at al udsivet kødsaft eller fugtighed fra givne fødevarer absorberes.By varying the size of the center field, the thickness of the layer of liquid absorbing material (and possibly the height of the ribs above the bottom of the tray), the total liquid absorption capacity can be regulated in such a way that all exposed meat juice or moisture from given foods is absorbed.

For at modvirke bakterievækst i det væskeabsorberende materiale med opsuget kødsaft kan laget ifølge opfindelsen være behandlet med et baktericid og/eller bakteriostatisk middel.To counteract bacterial growth in the liquid absorbent material with aspirated meat juice, the layer of the invention may be treated with a bactericidal and / or bacteriostatic agent.

I en plastbakke med indbyrdes krydsende ribber kan disse ifølge opfindelsen fortrinsvis være udformet med indsnit, som strækker sig fra ribbernes overkant til bakkens bund, hvorhos indsnittene er således anbragt, at hvert felt står i forbindelse med midterfeltet.Preferably, in a plastic tray with intersecting ribs, these according to the invention may be formed with incisions extending from the top of the ribs to the bottom of the tray, the incisions being arranged such that each field is in contact with the center field.

I tilfælde, hvor ribberne ikke krydser hinanden, bør de være anbragt på en sådan måde, at ethvert felt, som afgrænses af ribberne, gennem strømningspassager langs bakkens bund står i forbindelse med midterfeltet.In cases where the ribs do not intersect, they should be arranged in such a way that any field delimited by the ribs through flow passages along the bottom of the tray communicates with the center field.

Opfindelsen skal herefter beskrives nærmere under henvisning til tegningen, hvor 4 U5077The invention will now be described in more detail with reference to the drawing, in which 4 U5077

Fig. 1 viser en udførelsesform for en bakke ifølge opfindelsen set fra oven, fig. 2 viser et tværsnit gennem bakken ifølge fig. 1 efter linien II-II, og fig. 3 viser et tværsnit gennem bakken ifølge fig. 1 efter linien III-III.FIG. 1 is a plan view of one embodiment of a tray according to the invention; FIG. 2 shows a cross section through the tray according to FIG. 1 along line II-II; and FIG. 3 shows a cross section through the tray according to FIG. 1 along line III-III.

Den på tegningen viste rektangulære bakke har sidevægge 1, der skråner op fra en bund 2, som ved hjælp af ribber er opdelt i en række mindre felter 3 og et midterfelt 4.De tværgående ribber 5 er højere end de langsgående ribber 6, idet man herved opnår en bedre afstivende virkning end i det tilfælde, hvor ribberne 5 og 6 er lige høje. I ribberne 5 og 6 er der udformet indsnit 7, som strækker sig fra ribbernes øverste kant til bakkens bund. Indsnittene 7 er således anbragt, at hvert felt 3 er i forbindelse med midterfeltet 4. I midterfeltet 4 er der ved bakkens bund 2 anbragt et lag 8 af et væskeabsorberende materiale f.eks. af cellulosefibre.The rectangular tray shown in the drawing has side walls 1 which slope up from a bottom 2 which is divided by means of ribs into a number of smaller squares 3 and a middle field 4. The transverse ribs 5 are higher than the longitudinal ribs 6, thereby achieving a better stiffening effect than in the case where the ribs 5 and 6 are equally high. In the ribs 5 and 6, incisions 7 are formed which extend from the upper edge of the ribs to the bottom of the tray. The incisions 7 are arranged so that each field 3 is in contact with the middle field 4. In the middle field 4, a layer 8 of a liquid-absorbing material is arranged at the bottom of the tray 2, for example. of cellulose fibers.

Som omtalt ovenfor er bakken beregnet til understøtning af væskeafgivende fødevarer, der sammen med bakken emballeres, ved at varerne og bakken omsluttes af en folie f.eks. en plastkrympefolie, som, når den strammes, udøver et relativt kraftigt tryk på bakkens sidevægge 1. For at afstive disse er hver ribbe 5,6 ved enderne afsluttet med en i væggen indpresset forstærkningsribbe 9 henholdsvis 10.As discussed above, the tray is intended to support liquid dispensing foods which are packaged with the tray by enclosing the goods and the tray with a foil e.g. a plastic shrink wrap which, when tightened, exerts a relatively strong pressure on the sidewalls of the tray 1. To support these, each rib 5.6 is terminated at the ends with a reinforcing rib 9 pressed into the wall and 10, respectively.

Til yderligere afstivning af sidevæggene 1 er disse foroven udformet med en udad- og nedadrettet forstærkningskant 11.For further stiffening of the side walls 1, these are formed at the top with an outward and downward reinforcing edge 11.

Den viste bakke har, selv når den er fremstillet af et tyndt materiale, en betydelig stivhed dels på grund af den særlige udformning af væggene og dels på grund af ribbernes tilstedeværelse.The tray shown, even when made of a thin material, has a considerable stiffness partly due to the special design of the walls and partly due to the presence of the ribs.

Bakken fremstilles hensigtsmæssigt ved vakuumformning, og den jævnt buede overgang mellem ribber 5,6 og sidevæggene 1 giver bakken en betydelig modstand mod iturivning.The tray is conveniently prepared by vacuum forming, and the evenly curved transition between ribs 5.6 and the side walls 1 gives the tray considerable resistance to tearing.

Som følge af tilstedeværelsen af de nævnte indsnit 7 vil væske, hvad enten denne er kødsaft eller væske, som afgives fra varernes overflade, langs bunden 2 af bakken kunne strømme fra ethvert felt 3 til midterfeltet 4, hvori den vil blive opsuget i laget 8 af væskeabsorberende materiale.Due to the presence of said notches 7, liquid, whether it is meat juice or liquid which is dispensed from the surface of the goods, could flow along the bottom 2 of the tray from any field 3 to the middle field 4 in which it will be absorbed in the layer 8 of liquid absorbing material.

I stedet for at udforme bakken med hinanden krydsende ribber 5,6 kan ribberne være anbragt i et vilkårligt andet mønster, hvormed der . sker en opdeling af bakken i felter, og der kan i sådanne tilfælde være tilvejebragt strømningspassager langs bakkens bund fra disse felter til midterfeltet 4 på anden måde end ved hjælp af indsnit 7 i 5 145077 ribberne 5,6. For eksempel kan der være udformet et system af korte og lange parallelt anbragte ribber med strømningspassager mellem ribberne og ved disses ender.Instead of forming the tray with intersecting ribs 5.6, the ribs may be arranged in any other pattern by which. For example, a division of the tray into fields occurs, and in such cases, flow passages along the bottom of the tray may be provided from these fields to the middle field 4 by means other than by means of incision 7 in the ribs 5,6. For example, a system of short and long parallel ribs may be provided with flow passages between the ribs and at their ends.

Ydermere kan midterfeltet 4 strække sig fra den ene endevæg til den anden eller fra den ene sidevæg til den anden.Furthermore, the middle panel 4 may extend from one end wall to the other or from one side wall to the other.
