Description

DK 157483 BDK 157483 B

Opfindelsen angår en engangsemballage med låg af tyndvægget materiale, såsom aluminium, formstof eller andet formbart materiale, hvilken emballage især er til platter eller lignende beholdere, og 5 hvilket låg har en i lågfladen udformet profilering, der er asymmetrisk i forhold til lågets centrum, med rundtgående bertlekantstrimmel og med gribeflige.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a disposable, thin-walled, lid-like material, such as aluminum, plastic or other moldable material, which is particularly suitable for plates or similar containers, and which has a lid-shaped profile which is asymmetrical with respect to the center of the lid. circular birch edging strip and with gripping tabs.

Der kendes sådanne emballager med stabelbare låg.Such packages with stackable lids are known.

Ud over kravet om stabelbarhed og let fjernelse af 10 låg fra stablen skal lågene om muligt også opfylde et yderligere krav: De skal være lette at åbne uden risiko for, at dele af indholdet i den fyldte engangs-beholder ved pludselig utilsigtet oprulning eller revnedannelse spredes ved åbning. Ved åbning skal 15 låget om muligt kunne fjernes fuldstændigt i een operation. En fjernelse i form af to dele ville dog være acceptabel. Åbningen frembyder bl.a. derfor et særligt problem, fordi låget ved ombertling ved den rundtgående bertlekant på engangsbeholderen må lukke 20 denne engangsbeholder tætsluttende.In addition to the requirement for stackability and easy removal of 10 lids from the stack, the lids must also meet an additional requirement if possible: They must be easy to open without risk of parts of the contents of the filled disposable container being dissipated by sudden unintentional roll-up or cracking upon opening. When opened, the lid should be removable if possible in one operation. However, a two-part removal would be acceptable. The opening offers, among other things, therefore, a particular problem is that the lid, when recirculating at the circumferential berth edge of the disposable container, must close this disposable container tightly.

Der er ved en kendt emballage i dennes lås tilvejebragt gribeflige, ved hjælp af hvilke bl.a. åbningen af den lukkede engangsemballage skal lettes. For især at forbedre stabelbarheden af lågene yderligere, er 25 der udformet profileringer ved disse gribeflige, hvorhos gribefligene tillige er udformet fortrinsvis af forskellig udragende længde. De overfor hinanden liggende gribefligsprofileringer er udformet fortsat for hinanden for således at lette fjernelsen fra stablen.Grab tabs are provided by a known package in its lock, by means of which, inter alia, the opening of the closed disposable packaging must be facilitated. In particular, to further improve the stackability of the lids, profiles are formed at these gripping tabs, the gripping tabs also being preferably formed of different projecting lengths. The opposite grip tab profiles are still formed for each other so as to facilitate removal from the stack.

30 Det har vist sig, at disse gribeflige alligevel ikke sikrer en optimal åbning af lågene.30 It has been found that these gripping flaps do not, however, ensure an optimal opening of the lids.

Det er derfor formålet med den foreliggende opfindelse at videreudvikle låget således, at det let, veldefineret 2It is therefore the object of the present invention to further develop the lid so that it is light, well defined 2

DK 157483 BDK 157483 B

og om muligt fuldstændigt kan fjernes fra den lukkede engangsemballage uden fare forf at engangsemballagens indhold ved åbning utilsigtet spredes eller løber ud.and, if possible, can be completely removed from the closed disposable packaging without danger of unintentionally spreading or discharging the contents of the disposable packaging upon opening.

Dette formål opnås ved de i den kendetegnende del af 5 krav 1 angivne foranstaltninger.This object is achieved by the measures specified in the characterizing part of claim 1.

Ved udformningen af engangsemballagen ifølge opfindelsen er låget på veldefineret vis afriveligt på et vilkårligt sted på den rundt gående gribeflig eller langs en sik og videre under bertlingen. Ved udformningen af et indsnit 10 eller en indkærvning ifølge opfindelsen ved en sik opstår en oprivningsflig, som ved oprivningen veldefineret rives af langs sikken. Ved den bredere bertlekantstrimmel eller den ekstra gribefligstrimmel dannes også ved de sider, hvor der ingen gribeflig er, en smal, nedadrettet, 15 rundtgående gribeflig. Mellem bertlingen og denne flig opstår ved bertleoperationen en relativt skarp, rundtgående knæklinie, hvilket resulterer i en materialesvækkelse og dermed en forudbestemt oprivningslinie, langs hvilken låget ved oprivning afrives nøjagtigt, relativt 20 let og veldefineret uden anvendelse af større kræfter.In the design of the disposable packaging according to the invention, the lid is well-peelable at any point on the circumferential gripping tab or along a sieve and onward during the bursting. In the design of a notch 10 or a notch according to the invention in a sieve, a tearing tab is formed which, when teared up, is well torn off along the sieve. A wider, downward, circumferential gripping tab is also formed at the sides of which there is no gripping tab at the wider berth edge strip or the extra gripping tab strip. Between the bertle and this tab, the bertle operation produces a relatively sharp, circumferential crack line, which results in a weakening of the material and thus a predetermined tear line, along which the tear lid is accurately, relatively lightly and well defined without the use of greater force.

Når sikken og dermed indsnittet eller indkærvningen er udformet skråt, således som dette er præciseret i en yderligere udførelsesform for opfindelsen i krav 5, opnås en gunstigere oprivningsovergang af gribefligen 25 over bertlingen i knæklinien mellem bertlingen og fligen.When the sieve and thus the incision or notch is formed obliquely, as is specified in a further embodiment of the invention in claim 5, a more favorable tear-off transition of the gripping tab 25 is obtained across the bar in the knuckle line between the bar and the tab.

Når en gribefligs sikker er skråt udformet, behøver lågets andre modsat liggende gribefligs sikker ikke mere at anbringes forskudt for at forbedre fjernelsen fra stablen. 1When a gripper tab safe is inclined, the lid of the other opposite gripping tab safe no longer needs to be staggered to improve removal from the stack. 1

Hvis der er tilvejebragt flere gribeflige, kan disse også være forsynet med indsnit og indkærvninger, således som angivet i krav 6. Fortrinsvis er indsnittet eller 3If multiple gripping tabs are provided, they may also be provided with incisions and notches, as set forth in claim 6. Preferably, the incision or 3

DK 157483 BDK 157483 B

indkærvningen herved udformet langs en knæklinie på en sik, således som angivet i krav 7.the notch thereby formed along a knuckle line of a sieve, as defined in claim 7.

Udformningen af låget ifølge opfindelsen som angivet i krav 8 og 9 bevirker, at låget allerede ved frem-5 stillingen kan fremstilles med et forudbestemt opriv-ningsområde i form af en rundtgående materialesvækkelse i det senere bertlekantområde eller den senere bertling, eller at det forudbestemte oprivningsområde kan fremstilles i form af en rundtgående materialesvækkelse ved bert-10 leoperationen, også ved lukning af emballagen.The design of the lid according to the invention as claimed in claims 8 and 9 means that the lid can already be manufactured at the manufacture with a predetermined tear region in the form of a circumferential material weakening in the later bracket edge or the later bristle or that the predetermined tear region can be produced in the form of a circumferential material weakening during the berth operation, also by closing the package.

Den begyndende afrivning ud fra gribefligen kan foretages på et vilkårligt sted langs lågets omkreds. Åbningen af en lukket engangsemballage lettes væsentligt.The initial tearing from the gripping tab can be made at any location along the perimeter of the lid. The opening of a closed disposable packaging is greatly facilitated.

Lågdele, der ruller sig op, er elimineret. Paren for 15 spredning af indholdet i emballagen ved dennes åbning er praktisk taget fuldstændigt borte. Låget udformet ifølge opfindelsen kan efter rundtgående afrivning løftes af emballagen praktisk taget som et helt plant låg.Lids that roll up are eliminated. The pair for spreading the contents of the package at its opening is practically completely gone. The lid formed in accordance with the invention can be lifted by the packaging practically as a completely flat lid after circumferential tearing.

Opfindelsen vil nu blive forklaret nærmere i forbindel-20 se med nogle udførelsesformer og under henvisning til tegningen, hvor fig. 1 og 2 viser låget til emballagen ifølge opfindelsen set ovenfra, fig. 3 et snit A-A i fig. 1 eller 2 gennem låget i ubert-25 let tilstand, fig. 4 et snit B-B i fig. 1 eller 2 gennem låget i ubert-let tilstand, fig. 5 et Bnit A-A i fig. 1 eller 2 gennem låget i ombert-let tilstand, 30 fig. 6 et snit B-B i fig. 1 eller 2 gennem låget i ombert-let tilstand, fig. 7 skematisk et snit gennem låget til en emballage 4The invention will now be explained in more detail with reference to some embodiments and with reference to the drawing, in which fig. 1 and 2 are top views of the lid of the packaging according to the invention; FIG. 3 is a section A-A of FIG. 1 or 2 through the lid in an undisturbed state; FIG. 4 is a section B-B of FIG. 1 or 2 through the lid in an undisturbed state; FIG. 5 is a section A-A of FIG. 1 or 2 through the lid in the inverted state; FIG. 6 is a section B-B of FIG. 1 or 2 through the lid in the inverted state; FIG. 7 shows a schematic section through the lid of a package 4

ifølge opfindelsen, fig. 8 en videreudformning af låget ifølge opfindelsen, og fig. 9 i snit et engangsemballagelåg ifølge fig. 7 og 8 5 i ombertlet tilstand.according to the invention, fig. 8 shows a further embodiment of the lid according to the invention, and FIG. 9 is a sectional view of a disposable packaging lid according to FIG. 7 and 8 5 in the inverted state.

Tegningen viser et låg 2 med rundtgående, opad hvælvet kant 4 og en dermed forbundet, nedadbøjet bertlekant-strimmel 6 og desuden rundtgående gribefligsstrimler 46.The drawing shows a lid 2 with circumferential, upwardly curved edge 4 and an associated bent downward curved strip 6 and in addition circumferential gripping tab strips 46.

Ved to modsatte lågsider er der på hver side tilvejebragt 10 en udadvendende gribefligsforlængelse 8 henholdsvis 10.At two opposite cover sides, 10 is provided on each side an outwardly extending gripper tab extension 8 and 10 respectively.

Låget har en rektangulær form med afrundede hjørner 12, 14,16 og 18. Gribefligsforlængelserne er udformet ved de korte rektangelsider 20, 22; me® de kan også være udformet ved de lange rektangelsider 24, 26 eller ved alle 15 rektanglets sider.The lid has a rectangular shape with rounded corners 12, 14,16 and 18. The gripper tab extensions are formed at the short rectangular sides 20, 22; they may also be formed at the long rectangular sides 24, 26 or at all 15 rectangular sides.

På lågoverfladen 28 er udformet en asymmetrisk beliggende profilering 30.On the lid surface 28 is formed an asymmetrical profiling 30.

Som vist i fig. 1 og 2 er gribefligsforlængelserne ligeledes forsynet med en profilering i form af sikker 32.As shown in FIG. 1 and 2, the gripper tab extensions are also provided with a profiling in the form of secure 32.

20 Sikkerne 32 er som vist ribbeagtige forhøjninger og kan i snit eksempelvis være udformet rektangulært eller trapezformet. Sikkerne kan forløbe vinkelret, jvf. fig.20 As shown, the collars 32 are rib-like elevations and may, for example, be rectangular or trapezoidal in shape. The collars can extend perpendicularly, cf.

1, eller skråt, jvf. fig. 2, i forhold til rektangelsiderne. Som vist kan gribefligsforlængelserne have 25 forskellig bredde.1, or oblique, cf. 2, relative to the rectangle sides. As shown, the gripper wing extensions can have 25 different widths.

Langs i det mindste en sikke 32, dvs. fortrinsvis langs en knæklinie 34 på denne sikke, er der tilvejebragt et indsnit 36 eller en indkærvning 38. Dette indsnit eller indkærvning behøver ikke forløbe over hele 30 sikkens længde, se henvisningsbetegnelser 40 og 42 i fig. 1 og 2.Along at least a sieve 32, ie. preferably along a crack line 34 of this sack, a notch 36 or notch 38 is provided. This notch or notch does not have to extend over the entire length of the bag, see reference numerals 40 and 42 of FIG. 1 and 2.

I ombertlet tilstand forbliver den nedad rettede gribefligstrimmel 46 neden under den af bertlekant-strimlen formede bertling 44, hvilken gribefligstrimmel danner en relativt kort gribeflig 48 ved de ikke 5 med gribefligforlængelser 8 og 10 forsynede rektangelsider 24 og 26.In the inverted state, the downwardly directed gripping tab strip 46 remains beneath the bertle edge strip formed by the bevel edge strip, which forms a relatively short gripping tab 48 at the rectangular extensions 8 and 10 not provided with rectangle tabs 24 and 26.

Ved bertleoperationen opstår der mellem bertlingen 44 og strimlen 46 eller fligen 48 en relativt skarp knæklinie 50, som er udformet rundtgående neden under bert-10 lingen 44. Denne knæklinie 50 danner en slags forudbestemt oprivningslinie. Hvis nemlig låget 2 eksempelvis afrives begyndende ved gribefligen 8 langs indsnittet 36 henholdsvis 40 eller indkærvningen 38 henholdsvis 42, da afrives låget relativt let nøjagtigt rundt langs 15 knæklinien 50. Låget 2 er også på veldefineret vis af-riveligt langs bertlingen uden at være forsynet med indsnit eller indkærvninger. Låget kan således løftes af emballagen som en enhed.In the bertle operation, a relatively sharp crack line 50 is formed between the cantilever 44 and the strip 46 or tab 48, which is formed circumferentially below the cantilever 44. This crease line 50 forms a kind of predetermined tear line. For example, if the lid 2 is torn off starting at the gripping tab 8 along the incision 36 or 40 or the notch 38 and 42, respectively, then the lid is torn off easily easily around the crack line 50. The lid 2 is also peelable along the bar without being provided with incisions or notches. Thus, the lid can be lifted by the packaging as a unit.

Overgangen fra indsnittet 36 henholdsvis 40 eller ind-20 kærvningen 38 henholdsvis 42 til knæklinien 50 under bertlingen 44 lettes derved, at sikkerne 32 som vist i fig. 2 ikke forløber vinkelret, men skråt i forhold til lågsiden eller til bertlekanten.6.The transition from the incision 36 or 40 or 20 notch 38 and 42, respectively, to the crack line 50 during the burst 44 is thereby facilitated to secure 32 as shown in FIG. 2 does not extend perpendicularly but obliquely to the lower side or to the vertebra.6.

I fig. 1 er vist, at tillige også den anden flig 10 25 kan være forsynet med et indsnit 52 og en indkærvning 54 for i givet fald at kunne påbegynde afrivningsoperationen påny, ifald afrivningen langs knæklinien 50 ikke skulle kunne foretages i en operation.In FIG. 1, it is shown that the second tab 10 25 may also be provided with a notch 52 and a notch 54 in order to be able to start the tear-off operation again, if the tearing along the breakline 50 should not be possible in an operation.

Fig. 7 og 9 viser et låg 2, 2' med en lågflade 4 og en 30 rundtgående bertlekantstrimmel 6, og en dertil tilsluttet gribefligstrimmel 8. Bertlekantstrimlen 6 har i det mindste nogle steder en ringere styrke end de øvrigeFIG. 7 and 9 show a lid 2, 2 'with a lid surface 4 and a circumferential bertang strip 6, and a gripping tab strip 8 connected thereto. The Bertle edge strip 6 has at least in some places a lower strength than the other

e dele af låget. I fig. 9 er låget 2' vist i ombertlet tilstand på en emballage 10'. De materialesvækkede bertlekantstrimler 6 er herved bertlet omkring en rundtgående bertlekant eller rundtgående vulst 12.e parts of the lid. In FIG. 9, the lid 2 'is shown in an inverted state on a packaging 10'. The material weakened bead edge strips 6 are thereby beaded around a circumferential bead edge or circumferential bead 12.

5 Herved rager gribef Iigstriira1.ai:ne8 ud i nedadgående retning.5 Hereby the vulture Iigstriira1.ai:ne8 protrudes in a downward direction.

I fig. 8 vises en speciel mulighed for at svække lågets bertlekantstrimmel veldefineret med henblik på oprivningsoperationen? bertlekantstrimlen får ved 10 formændring, i dette tilfælde ved prægning, form som en indad hvælvet sik 6', fig. 8 til venstre, eller en udad hvælvet sik 61', fig. 8 til højre. Sikken kan forløbe anderledes end vist, f.eks. bueformet.In FIG. 8 does a special opportunity appear to weaken the lid edge strip well defined for the tearing operation? at 10 change of shape, in this case by embossing, the bertle edge strip takes the form of an inwardly curved screen 6 '; 8 to the left, or an outwardly curved screen 61 '; FIG. 8 to the right. The sieve may proceed differently than shown, e.g. arcuate.

Ved materialesvækkelsen opstår et forudbestemt opriv-15 ningsområde 6, 6', 6'', langs hvilket låget 2, 2' er afriveligt uden besvær og på veldefineret vis praktisk taget ved emballagens 10' omkreds, således at det efter afrivning er aftageligt fra emballagen praktisk taget som et helt låg.In the weakening of the material, a predetermined tear region 6, 6 ', 6' 'arises, along which the lid 2, 2' is easily peelable and practically defined at the circumference of the packaging 10 ', so that after tearing it is removable from the packaging. practically as a whole lid.
