Description
454 437 _ _ 2 ILPOÛR _En annan känd lösning på problemet med köttsaft i förpack- ningen är att man utformar bottsnstycket av tråget med djupa, mycket smala rännor, i vilka köttaaften kvarhålles genom ka- pillärkraftens inverkan. 454 437 _ _ 2 ILPOÛR _Another known solution to the problem of meat juice in the package is to design the bottom piece of the trough with deep, very narrow grooves, in which the meat juice is retained by the action of the capillary force.
Att utforma ett tråg på detta vis är emellertid behäftat med avsevärda problem. Man är begränsad i materialvalet, eftersom endast tunnväggiga material är möjliga att använda i en termo- formningsprocess, som resulterar i kapillärkanaler. Men även med tunn folie uppstår betydande produktionsproblem och hög kassation, då risken för brott uppenbarligen är mycket stor vid ett sådant djupdragningsförfarande. Med perforation i kapillär- kanalerna saknar tråget givetvis de åsyftade egenskaperna.Designing a trough in this way, however, has considerable problems. The choice of material is limited, as only thin-walled materials can be used in a thermoforming process, which results in capillary channels. But even with thin foil, significant production problems and high scrapping arise, as the risk of breakage is obviously very high in such a deep-drawing procedure. With perforation in the capillary channels, the trough of course lacks the intended properties.
Föreliggande uppfinning syftar till att undanröja ovannämnda problem av ekonomisk och tillverkningsteknisk art och samtidigt ge en effektiv lösning av problemet med köttsaft i beskriven typ av förpackning.The present invention aims to eliminate the above-mentioned problems of an economic and manufacturing nature and at the same time provide an effective solution to the problem of meat juice in the type of packaging described.
För att ge befintliga adhesionskrafter mellan vätska och trågyta optimala möjligheter att verka, är det inte nödvändigt att till- gripa så extrema lösningar som kapillärkanaler. Redan vid måttliga fördjupningar i material ökar tendensen till kvarhållning av droppar i resp fördjupning. Väljs materialet dessutom så, att ytan uppvisar en viss skrovlighet, förstärks ytterligare adhe- sionskrafterna mellan vätska och behållarmateríal. Olika typer av expanderade, porförsedda plastmaterial uppvisar just en ytstruktur av önskad karaktär med avsevärt ökade adhesionsegen- skaper jämfört med homogena plastfolier. Vid föreliggande upp- fínning utnyttjas dessutom cellstrukturer i materialet till att ytterligare öka festhållningen av vätska.In order to give existing adhesion forces between liquid and trough surface optimal opportunities to operate, it is not necessary to resort to such extreme solutions as capillary channels. Even with moderate depressions in material, the tendency to retain droplets in the respective depression increases. In addition, if the material is selected so that the surface exhibits a certain roughness, the adhesion forces between liquid and container material are further enhanced. Different types of expanded, pore-provided plastic materials have a surface structure of the desired character with considerably increased adhesion properties compared with homogeneous plastic foils. In the present invention, cell structures in the material are also used to further increase the adhesion of liquid.
Uppfinningen kommer i det följande att beskrivas närmare i anslutning till den på ritningen visade utföringsformen, där fig. 1 visar ett tvärsnitt genom ett förpackningstråg och ' fig. 2 visar ett tråg sett från ovansidan. 3 454 437 Uppfínningen avser ett tråg 1, som är tillverkat i expanderat plastmaterial och med i förhållande till bottenytan 2 relativt låga sidoväggar 3.The invention will be described in more detail in the following in connection with the embodiment shown in the drawing, in which Fig. 1 shows a cross section through a packaging tray and Fig. 2 shows a tray seen from above. The invention relates to a trough 1, which is made of expanded plastic material and with relatively low side walls 3 relative to the bottom surface 2.
Bottenytan 2 av tråget 1 är utformad med skålformade fördjup- ningar 4, vilka kan vara av olika typ såsom exempelvis runda, ovala, tríangulära etc. (se fig. 2). Fördjupningarnas 4 djup väljs normalt att motsvara deras minsta öppningsmått. Då botten- ytan 2 har runda fördjupningar 4 är dessas diameter av samma storleksordning som djupet.The bottom surface 2 of the trough 1 is formed with bowl-shaped depressions 4, which can be of different types such as, for example, round, oval, triangular, etc. (see Fig. 2). The depths of the depressions 4 are normally chosen to correspond to their smallest opening dimensions. When the bottom surface 2 has round depressions 4, their diameter is of the same order of magnitude as the depth.
I botten på varje skålformad Fördjupning 4 finns en i jämförelse med denna liten, ytterligare iördjupning 5. Denna ytterligare för- djupning 5 har åstadkommits genom utformning av formningsverk- tyget på ett sådant sätt, att plastmaterialet vid dragning mot verktygets utskjutande spets kommer att brista i ytskiktet i de väggar, som omsluter hålrummet A eller ligger öppna in mot hålig- heten. I denna brustna yta ökas på grund av ojämnheterna adha- sionskrafterna mellan materialet i tråget och vätska avsevärt.At the bottom of each cup-shaped depression 4 there is a small, further soil depression 5 in comparison with this. the surface layer in the walls which enclose the cavity A or are open towards the cavity. In this broken surface, due to the irregularities, the adhesion forces between the material in the trough and the liquid increase considerably.
Trågets förmåga att kvarhâlla köttsaft i de skålformade för- djupningarna 4 med den beskrivna kaviteten 5 i botten kommer därför att förbättras avsevärt. ..»...,.\a._........The ability of the trough to retain meat juice in the bowl-shaped depressions 4 with the described cavity 5 at the bottom will therefore be considerably improved. .. »...,. \ A ._........
