Opfindelsen angår et dybtrukket metallåg til en beholder med vulstformet eller ombertlet kant, hvilket låg har en bund og en rundtgående, fra bunden fremstående randzone, der slutter i en ombertlet kant og har 5 mindst ét i retning mod lågets indre deformeret vægafsnit, som danner et låseorgan, der er bestemt til at gribe om beholderens vulstformede eller ombertlede kant.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a deep-drawn metal lid for a bead-shaped or fluted edge container, which has a bottom and a circumferential rim zone ending in a fluted edge and having at least one towards the inner deformed wall portion of the lid forming a locking means intended to grip the bead-shaped or fluted edge of the container.

Et sådant låg kendes fra GB-A-881 225.Such a lid is known from GB-A-881 225.

10 Dette kendte låg har dog ikke nogen inden for lågets randzone beliggende afrivningsfane og tillader ikke nogen trykudligning mellem beholderens indre og omgivelserne.However, this known lid has no tear tab within the lid zone and does not allow any pressure equalization between the interior of the container and the surroundings.

Opfindelsen tager sigte på at angive et dybtruk-15 ket metallåg til en beholder med vulstformet eller ombertlet kant, hvilket låg har en ikke ud over lågets kontur ragende afrivningsfane, tillader trykudligning og er fremstillet udelukkende ved dybtrækning.The invention has for its object to provide a deep-drawn metal lid to a container with a bead-shaped or fluted edge, which lid has a tear-off tab which does not extend beyond the contour of the lid, allows pressure equalization and is made exclusively by deep drawing.

Til opnåelse heraf er metallaget ifølge opfin-20 delsen ejendommeligt ved de i krav 1 angivne træk.To achieve this, the metal layer according to the invention is characterized by the features of claim 1.

De ved opfindelsen opnåede fordele skal i det væsentlige ses i, at der ved foranstaltningerne er opnået et til brug på en beholder med vulstformet eller ombertlet kant egnet metallåg, der nemt lader sig fjer-25 ne fra beholderen og er uafhængigt af dennes materiale, der har en ikke ud over lågets kanter ragende afrivningsfane, således at der ikke er fare for, at fanen skal hænge i et eller andet under håndteringen af den med låget lukkede beholder, og som uden videre tillader 30 opvarmning af beholderens indhold.The advantages of the invention are to be seen, in essence, in the fact that by the measures there is obtained a metal lid suitable for use on a bead-shaped or fluted edge, which is easily removable from the container and independent of its material which has a tear-off tab not extending beyond the edges of the lid, so that there is no danger that the tab will hang in one or the other while handling the lid closed container, and which will readily permit heating of the contents of the container.

Udførelsesformer for låget ifølge opfindelsen fremgår af kravene 2-7.Embodiments of the lid according to the invention are set forth in claims 2-7.

Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, på hvilken 35 fig. 1 er et planbillede af et dybtrukket me tallåg ifølge opfindelsen,The invention will now be explained in more detail with reference to the drawing, in which: FIG. 1 is a plan view of a deep drawn metal lid according to the invention,

2 fig. 2 et snit efter linien Il-Il i fig. l, fig. 3 et til fig. 2 svarende snit i en alternativ udførelsesform, og fig. 4 et snit efter linien IV-IV i fig. 1.2 FIG. 2 is a sectional view taken along the line II-II in FIG. 1, FIG. 3 is a view of FIG. 2 corresponding to an alternative embodiment, and FIG. 4 is a section along line IV-IV of FIG. First

5 Den i fig. 1 viste udførelsesform for beholder låget er bestemt til anvendelse sammen med en beholder, der har en vulstkant eller en ombertlet kant, og beholderen kan være fremstillet af metal eller fx porcelæn. Sådanne beholdere anvendes fx i passagerfly, idet be-10 holderens indhold opvarmes i flyets køkken til fortæring.5 The embodiment of FIG. 1 the container lid shown is intended for use with a container having a bead edge or a fluted edge, and the container may be made of metal or, for example, porcelain. Such containers are used, for example, in passenger aircraft, the contents of the container being heated in the kitchen of the aircraft for consumption.

Beholderlåget er dybtrukket af fx aluminium eller en aluminiumlegering.The container lid is deep-drawn, for example, aluminum or an aluminum alloy.

Låget har en stort set plan bund 3, som er ud 15 i ét med en afrivningsfane 4. Ved hjælp af afrivningsfanen 4 kan låget rives bort fra beholderen. En rundtgående randzone 5 står frem fra lågbunden 3 og slutter med en ombertlet kant 6, således som det ses i fig. 2 og 3. Det er åbenbart, at låget 3 i planbil-20 lede kan have vidt forskellige faconer overensstemmende med den beholder, som skal lukkes. Randzonen 5 kan ligeledes have forskellige tværsnitsformer. Den viste udførelsesform for beholderlåget er udformet svarende til en beholder 1 med en vulstkant 2, som er an-25 tydet med stiplede linier i fig. 2 og 3.The lid has a substantially flat bottom 3, which is 15 in unison with a tear-off tab 4. By means of the tear-off tab 4, the lid can be torn away from the container. A circumferential rim zone 5 emerges from the lid bottom 3 and terminates with a fluted edge 6, as seen in FIG. 2 and 3. It is evident that the lid 3 in plan view may have widely different shapes according to the container to be closed. The edge zone 5 may also have different cross-sectional shapes. The embodiment of the container lid shown is similar to a container 1 with a bead edge 2 indicated by dashed lines in FIG. 2 and 3.

Randzonen 5 har mindst ét vægafsnit 7, som er deformeret i retning mod lågets indre, således som det er vist i fig. 2 og 3. Det deformede vægafsnit 7 forløber i en første udførelsesform sammenhængende 30 langs den rundtgående randzone 5. I en anden udførelsesform er der flere indbyrdes adskilte deformerede vægafsnit 7, som kan være punkt- eller linieformede deformationer af randzonen 5. Som antydet med de fire henvisningstal 7 i fig. 1 har den viste udførelses-35 form fire deformerede vægafsnit 7.The edge zone 5 has at least one wall section 7 which is deformed towards the interior of the lid, as shown in FIG. 2 and 3. In a first embodiment, the deformed wall section 7 extends continuous 30 along the circumferential rim zone 5. In a second embodiment, there are several mutually deformed wall sections 7 which may be point or line deformations of the rim zone 5. As indicated by the four reference numerals 7 in FIG. 1, the embodiment shown has four deformed wall sections 7.

I udførelsesformen i fig. 3 er hvert af de deformerede vægafsnit gennembrudt ved hjælp af en i lå-In the embodiment of FIG. 3, each of the deformed wall sections is pierced by means of a locking member.

3 gets omkredsretning forløbende slids 10. Herved opstår der, svarende til det anvendte materiale, eftergivende låseflige 8 og 9, som rager frem i retning mod lågets indre under en skæv vinkel. Alt efter den 5 ønskede udførelse kan der være en enkelt sådan låseflig, fx den i fig. 3 viste øverste låseflig 9, eller der kan findes to låseflige 8 og 9 som i udførelseseksemplet. Fordi låget og navnlig dets randzone 5 er eftergivende, kan det ved lukning af beholderen 1 10 uden videre trykkes ned over beholderens vulstformede eller ombertlede kant, hvorved de deformerede vægafsnit 7 eller låsefligene kommer til at ligge under vulsten 2, hvorved de forbinder låget fast med beholderen 1.3 of the circumferential direction extending slot 10. This produces, according to the material used, resilient locking tabs 8 and 9, which project in a direction towards the interior of the lid at an oblique angle. Depending on the desired embodiment, there may be a single such locking tab, e.g. 3, or two locking tabs 8 and 9 can be found as in the exemplary embodiment. Because the lid and in particular its border zone 5 are compliant, upon closing of the container 110 it can easily be pressed down over the bead-shaped or fluted edge of the container, whereby the deformed wall sections 7 or the locking tabs lie below the bead 2, whereby they connect the lid with container 1.

15 Beholderlåget er udstyret med en afrivningsfane 4, som er ud i ét med lågbunden 3. Afrivningsfanen 4 er skilt fra resten af lågbunden ved hjælp af en ikke-retliniet slids 11, se navnlig fig. 1 og 4.The container lid is provided with a tear-off tab 4 integral with the lid bottom 3. The tear-off tab 4 is separated from the rest of the lid bottom by a non-rectilinear slot 11, see in particular FIG. 1 and 4.

Slidsen 11 kan bestå af flere retliniede afsnit, som 20 parvis danner en vinkel med hinanden, eller forløbe efter en krum linie, fx en halvcirkel, som i den viste udførelsesform. I området for afrivningsfanen 4, som i fig. 1 og 4 er antydet med henvisnings tallet 12, har lågbunden 3 en indbugtning. Formålet med denne 25 udformning forklares senere.The slot 11 may consist of several rectilinear portions, which in pairs form an angle to each other, or extend along a curved line, for example a semicircle, as in the embodiment shown. In the region of the tear-off tab 4, as in FIG. 1 and 4 are indicated by the reference numeral 12, the lid bottom 3 has an indentation. The purpose of this design is explained later.

De to ender af den stort set halvcirkulære slids 11 er forbundet med hinanden ved hjælp af en rille 13, som af æstetiske grunde danner en langs beholderkanten forløbende lukket figur. Det afsnit af rillen 30 13, som forbinder de to ender af slidsen 11, forløber stort set retliniet. Herved opnås der på den ene side et nøjagtigt bestemt bukkested, når afrivningsfanen vippes op med henblik på afrivning af låget 3 fra beholderen, og på den anden side forebygges det, at 35 slidsen 11 rives videre gennem lågbunden 3 i retning mod dennes yderkant, når låget fjernes.The two ends of the substantially semicircular slot 11 are connected to each other by means of a groove 13, which for aesthetic reasons forms a closed figure extending along the container edge. The portion of the groove 30 13 connecting the two ends of the slot 11 extends substantially straight. Hereby, on the one hand, an precisely determined bending point is obtained when the tear tab is tilted up to tear off the lid 3 from the container, and on the other hand it is prevented that the slit 11 is further torn through the lid bottom 3 towards its outer edge when the lid is removed.

Som det især ses af fig. 4, er slidsen li, som afgrænser en del af afrivningsfanen 4, udformet i et afsnit 14 af lågbunden, der skråner indad mod lågbunden 3's indbugtning 12 i retning bort fra af-5 rivningsfanen 4. Endvidere er der i lågbunden 3 udformet en retliniet fold 15 på den side af slidsen 11, som vender bort fra rillen 13. Et afsnit 16 af lågbunden (se fig. 4) forløber fra folden 15 i retning mod fodpunktområdet 17 for det ligeledes nedad-10 hældende afsnit 14 af lågbunden, som indeholder slidsen 11. Lågbunden 3's indbugtning 12 dannes af de to skrånende afsnit 14 og 16 af lågbunden. Herved flugter ydersiden af afrivningsfanen 4 med det ude-deformerede afsnit af lågbunden 3, og slidsen 11 er 15 forsat i retning mod det indre af låget.As seen especially in FIG. 4, the slot 1 defining a portion of the tear-off tab 4 is formed in a section 14 of the lid bottom, which slopes inwardly against the indentation 12 of the lid-bottom 3 in the direction away from the tear-off tab 4. Furthermore, a rectilinear fold is formed in the lid-bottom 3. 15 on the side of the slot 11 which faces away from the groove 13. A section 16 of the lid bottom (see Fig. 4) extends from the fold 15 towards the foot-point area 17 of the downwardly inclined section 14 of the lid bottom containing the slot. 11. The bend 12 of the lid bottom 3 is formed by the two sloping sections 14 and 16 of the lid bottom. Hereby, the outer surface of the tear-off tab 4 flushes with the outwardly deformed portion of the lid bottom 3, and the slot 11 is positioned in a direction towards the interior of the lid.

I modsætning til tidligere afrivningsfaner rager afrivningsfanen 4 i denne udførelsesform ikke op over lågbunden 3. Dette betyder, at det er umuligt, at afrivningsfanen 4 kan komme til at hænge i nogen 20 steder i en transportbeholder for de fortillavede ret-ter, fx i et flykøkken eller ved genopvarmningen i flykøkkenet, hvorved den kunne blokere beholderen. Alligevel er det meget let at vippe afrivningsfanen 4 op, da det over slidsen 11 værende afsnit af lågbundens 25 skrånende afsnit 14 og tydeligvis slidsen 11’s kant uden videre kan løftes med fingerspidsen. Det viste arrangement af slidsen 11 har endnu en funktion, idet der under tilberedningen af beholderens indhold kan ske en afluftning, hvorved eventuel dannet damp kan strømme 30 ud af slidsen. Dermed er det forebygget, at der kan opstå overtryk i beholderen under opvarmningen af dens indhold.Unlike previous tear-off tabs, in this embodiment, the tear-off tab 4 does not extend over the lid bottom 3. This means that it is impossible for the tear-off tab 4 to hang in any 20 places in a transport container for the prepared dishes, e.g. airplane kitchen or by reheating in the airplane kitchen, allowing it to block the container. Still, it is very easy to tilt the tear tab 4, since the section 11 of the slanting section 25 of the lid bottom 25 and obviously the edge of the slot 11 can easily be lifted with the tip of the slit 11. The arrangement shown in the slot 11 has yet another function in that during the preparation of the contents of the container a venting can occur, whereby any steam formed can flow out of the slot. This prevents overpressure in the container during heating of its contents.

Når fanen 4 er vippet op omkring rillen 13, kan låget 3 uden videre trækkes af beholderen 1, 35 idet passageren løfter låget på den måde, at det først bringes ud af indgreb med beholderen l's vulstkant 2When the tab 4 is tilted around the groove 13, the lid 3 can be pulled out of the container 1, 35, the passenger lifting the lid in such a way that it is first brought out of engagement with the bead edge 2 of the container 1.
