Den foreliggende opfindelse angår et oprivningsdæksel af metal og med en rand, som kan fjernes langs en svækkelseslinie, og som på sikrende måde griber ind under en beholder-halsvulst eller en lignende mundingsring, og hvor der ved 5 randen, som kan fjernes, findes en fra denne rand udragende gribeflig, hvorhos der direkte over den indrullede rand ligger en svækkelseslinie.BACKGROUND OF THE INVENTION The present invention relates to a metal tear-off cover with a rim that can be removed along a line of weakening and which securely engages a container neck bead or similar mouth ring, and where at the rim which can be removed, a a gripping tab protruding from this edge, where there is a weakening line directly above the rolled edge.
Der kendes forskellige oprivningsdæksler af metal, som tjener til lukning af flasker og andre beholdere, og 10 som har en rand, der kan fjernes langs en svækkelseslinie, idet den ved åbning af beholderen afrives ved hjælp af en gribeflig, der rager frem over randen. Disse kendte oprivningsdæksler, i hvis omkredsoverflade der i givet fald kan være indtrykket gevind, har i første række det formål 15 at tjene som sikkerhedslukninger, dvs. at garantere førstebrugeren originalindholdet i den dermed lukkede beholder.Various metal tear-off covers are known which serve to close bottles and other containers, and 10 having a rim that can be removed along a line of weakening as it is teared open by a gripping tab projecting over the rim. These known tear-off covers, the circumferential surface of which may, where appropriate, be threaded, are primarily intended to serve as security closures, ie. to guarantee the first user the original contents of the closed container.
De er dog mindre egnede til anvendelse som tryklukninger til under tryk stående beholderindhold, idet deres styrke overfor indvendigt tryk er begrænset. Derudover må deres 20 omkredsoverflade indbefattet den aftagelige rand eller afrivningsstrimmel have en vis højde, hvilket medfører et tilsvarende materialeforbrug og yderligere bevirker, at kun beholdere, som har en tilsvarende høj beholderhals med snævre dimensionstolerancer, kan lukkes med disse 25 dæksler. Desuden lader afrivningsstrimlerne sig ved de kendte dæksler kun usikkert og ubekvemt afrive.However, they are less suitable for use as pressure closures for pressurized container contents, as their strength against internal pressure is limited. In addition, their 20 perimeter surface including the removable rim or tear strip must have a certain height, which results in a corresponding consumption of material and further causes that only containers having a correspondingly high container neck with narrow dimension tolerances can be closed with these 25 covers. Furthermore, the tear strips at the known covers can only be peeled off and uncomfortable.
Der kendes også oprivningsdæksler af metal, som har en indrullet rand. Disse dæksler har imidlertid den ulempe, at de ødelægges ved oprivningen, idet det 30 ikke er den indrullede rand, men en afrivningsstrimmel, som forløber tværs over dækslet, der afrives.Metal tear-off covers are also known which have a rolled edge. However, these covers have the disadvantage of being destroyed during tearing, as it is not the rolled-up rim but a tear-off strip which extends across the cover being torn off.
Formålet med den foreliggende opfindelse er at tilvejebringe et oprivningsdæksel af metal til lukning af flasker og andre beholdere, hvilket dæksel trods en 35 ringe højde garanterer en stor styrke overfor indvendigt tryk og en stor afrivningssikkerhed og samtidigt opfylder funktionen som sikkerhedslukning.The object of the present invention is to provide a metal tear-off cover for closing bottles and other containers, which despite a low height guarantee a high strength against internal pressure and a high tear-off security, while at the same time fulfilling the function of safety closing.

Dette formål opnås ifølge opfindelsen ved, at svækkelseslinien er afbrudt af en udsparing, der sammen med et fra svækkelseslinien gennem den indrullede rand forløbende snit eller et forud svækket afrivnings-5 sted begrænser afrivningsenden af randen, som kan afrives, hvorhos der ved afrivningsenden af randen ud for udsparingen er fastgjort en særlig gribeflig, der ligger an imod og delvis er befæstet til den ydre overflade af dækslet.This object is achieved according to the invention in that the weakening line is interrupted by a recess which, together with a cut-off extending through the rolled edge or a pre-weakened tear-off site, limits the tear-off end of the edge, which can be torn off, as at the tear-off end of the edge. next to the recess is attached a special gripping tab, which abuts and is partially attached to the outer surface of the cover.
Ved at anvende en særlig gribeflig, der er fastgjort 10 til den afrivelige rand, kan man spare materiale til selve dækslet. Det bliver endvidere muligt at udforme dækslet med en meget smal afrivningsrand og alligevel opnå en solid forbindelse mellem afrivefligen og randen.By using a special gripping tab attached 10 to the tear-off edge, material can be saved to the cover itself. Furthermore, it becomes possible to design the cover with a very narrow tear-off edge and yet achieve a solid connection between the tear-off tab and the edge.
Afrivningsenden kan på et sted foran gribefligen 15 have en hage eller en opad rettet holdeknast, der tjener til at forhindre, at gribefligen glider af.The tear-off end may have a hook or an upwardly directed holding cam at a location in front of the gripping tab 15 which serves to prevent the gripping tab from slipping off.
Det fra svækkelseslinien gennem den indrullede rand forløbende snit eller det forud svækkede afrivningssted kan være anbragt forskudt til siden for udsparingen 20 og dermed i afstand fra gribefligen, hvilket også bidrager til at forhindre, at denne glider af under op-rivningen.The section extending from the weakening line through the rolled-up edge or the pre-weakening tear-off location may be positioned offset to the side of the recess 20 and thus at a distance from the gripping tab, which also helps to prevent it from slipping during the tearing.
Gribefligen kan bestå af et klæbebånd i form af en plaststrimmel, der er belagt med klæbemiddel på 25 den ene side og i givet fald har en forstærket kant, og klæbebåndet kan ifølge opfindelsen forløbe gennem udsparingen og rundt omkring den indrullede rand således, at klæbefladen først er forbundet med sig selv på en kort strækning ovenfor den indrullede rand og derover på en 30 kort strækning klæber til dækslet, idet båndets yderste ende er ombøjet og klæbet mod sig selv. Herved opnås, at gribefligen forud for oprivningen af dækslet på en enkel måde kan fastholdes i tæt anlæg mod dækslet.The gripping tab may consist of an adhesive tape in the form of a plastic strip coated with adhesive on one side and, if applicable, having a reinforced edge and the adhesive tape may extend according to the invention through the recess and around the rolled edge so that the adhesive surface first is connected to itself a short distance above the rolled-up edge and, over a short distance, adheres to the cover, the outer end of the belt being bent and adhered to itself. Hereby it is achieved that the gripping tab prior to the tearing of the cover can be easily held in close contact with the cover.
Det med dækslet forbundne sted af klæbebåndet kan med 35 fordel befinde sig på dækslets overside.Advantageously, the location of the adhesive band associated with the cover may be on the upper side of the cover.

Alternativt kan gribefligen bestå af en plasteller metalfoliestrimmel, der er bøjet rundt om den indrullede rand og sammensvej set eller -nittet ud for udsparingen.Alternatively, the gripping tab may consist of a plastic or metal foil strip bent around the rolled edge and welded together or cut out for the recess.
5 Fortrinsvis er dækslet således udformet, at svækkelseslinien efter lukning af beholderen af hensyn til genanbringelse af dækslet ligger under beholderhals-vulsten eller mundingsringen.Preferably, the cover is designed such that the line of weakening after closure of the container for re-insertion of the cover is below the container neck bead or mouth ring.
Opfindelsen skal i det følgende forklares nærmere, 10 idet der henvises til tegningen, hvorpå: fig. 1 viser et sidebillede af et oprivningsdæksel ifølge opfindelsen, fig. 2a og 2b sidebilleder af oprivningsdæksler med delvis afrevne nedre kanter, 15 fig. 3 et snit langs linien A-B i fig. 1, fig. 4 et til fig. 3 svarende snit gennem en anden udførelsesform for oprivningsdækslet, fig. 5 et sidebillede af yderligere en udførelsesform for oprivningsdækslet, ved hvilken gribefligen er 20 udeladt, og fig. 6 et snit gennem en særlig beholderhals, som er lukket med et oprivningsdæksel ifølge opfindelsen.BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail below with reference to the drawing, in which: 1 is a side view of a tear-off cover according to the invention; FIG. Figures 2a and 2b are side views of tearing covers with partially torn lower edges; 3 is a section along line A-B of FIG. 1, FIG. 4 is a view of FIG. 3 shows a similar section through another embodiment of the tear-off cover; FIG. 5 is a side view of a further embodiment of the tear-off cover, in which the gripping tab 20 is omitted, and FIG. 6 is a section through a special container neck closed with a tear-off cover according to the invention.
Oprivningsdækslet har en rand 1, som kan fjernes, og som er indrullet på kendt måde og samtidigt tjener 25 som afrivningsbånd og sikringsbånd. Dækslet befæstes til beholderhalsen og forsegles mod uberettiget åbning af den udvendigt eller indvendigt indrullede rand 1, der ikke nødvendigvis behøver at være fuldstændig indrullet.The tear-off cover has a removable rim 1 which is rolled in known manner and at the same time serves as a tear-off strip and fuse strip. The cover is attached to the container neck and sealed against undue opening of the outer or inner rolled rim 1, which does not necessarily have to be fully rolled.
Direkte ovenfor den indrullede rand 1 ligger en 30 svækkelseslinie 2. Udtrykket "direkte ovenfor” omfatter også en afstand på ca. 1-1,5 mm. Ovenfor randen 1 og den denne begrænsende svækkelseslinie 2 kan dækslets omkredsoverflade på kendt måde være forsynet med et ikke vist gevind, der tjener til gentagne lukninger.Directly above the rolled rim 1 lies a line of weakening 2. The term "directly above" also includes a distance of about 1-1.5 mm. Above the rim 1 and this limiting line of weakening 2, the circumferential surface of the cover may in a known manner be provided with a not shown threads that serve for repeated closures.

Den direkte ovenfor den indrullede rand 1 -liggende svækkelseslinie 2, langs hvilken randen 1 afrives, er afbrudt af en udsparing 3. Denne udsparing 3, der f.eks. kan være en udstanset firkant eller en gennembrydning, 4 145776The weakening line 2 directly above the rolled edge 1, along which the rim 1 is torn off, is interrupted by a recess 3. This recess 3, e.g. may be a die-cut square or a breakthrough, 4 145776
OISLAND
der er gennemstukket med en dorn, begrænser sammen med et afrivningssted 4 afrivningsenden 6 af randen 1, der kan fjernes, og tjener til befæstelse af en særlig gribeflig 5.which is pierced with a mandrel, together with a tear-off point 4, limits the tear-off end 6 of the removable rim 1 and serves to secure a special gripping tab 5.
5 Afrivningsstedet 4 fremviser et snit eller en forud svækket linie, der rækker fra svækkelseslinien 2 gennem randen 1, som kan fjernes. Dette afrivningssted 4 er fortrinsvis anbragt forskudt til siden for udsparingen 3, som vist i fig. 1. Det kan dog også være anbragt 10 i direkte tilslutning til udsparingen 3, som vist i fig. 5.The tear-off site 4 shows a cut or a pre-weakened line extending from the weakening line 2 through the removable rim 1. This tear-off point 4 is preferably positioned offset to the side of the recess 3, as shown in FIG. However, it may also be located 10 in direct connection to the recess 3, as shown in FIG. 5th
Gribefligen 5 kan bestå af plast, tekstil eller metal, især et letmetal som aluminium. Særlig fordelagtigt er et farvet materiale, ved hjælp af hvilket gribefligen 15 fremtræder meget synligt.The gripping tab 5 may consist of plastic, textile or metal, especially a light metal such as aluminum. Particularly advantageous is a colored material by means of which the gripping tab 15 appears very visible.
Fortrinsvis består gribefligen 5 af et på den ene side belagt klæbebånd, der på sin side fordelagtigt består af en plaststrimmel med forstærket kant. I fig. 3 er yist et sådant klæbebånd, hvis ene ende er trukket 20 gennem udsparingen 3. Klæbebåndets længste ende forløber rundt omkring den indrullede rand 1 og er derefter på en kort strækning 9 samklæbet med klæbebåndets korte ende og yderligere på en kort strækning 10 med dækslet. Klæbebåndets yderste ende 11 klæber mod sig selv, 25 således at der fremkommer en fri flig, der er let at fatte om. Delene 10 og 11 kan dog også, især ved lave dæksler, være lagt hen over dækslets overside 12.Preferably, the gripping tab 5 consists of an adhesive tape coated on one side, which advantageously consists of a reinforced edge plastic strip. In FIG. 3 is such an adhesive tape, one end of which is pulled 20 through the recess 3. The longest end of the adhesive tape extends around the rolled edge 1 and is then, on a short stretch 9, adhered to the short end of the adhesive tape and further on a short stretch 10 with the cover. The outermost end 11 of the adhesive tape adheres to itself 25 so that a free tab is provided which is easy to grasp. However, the parts 10 and 11 may also, especially at low covers, be placed over the top 12 of the covers.
Til dette formål kan oversiden 12 være forsynet med en fordybning, således at den frie ende 11 af gribefligen 30 ikke rager udenfor.For this purpose, the top side 12 may be provided with a recess so that the free end 11 of the gripper tab 30 does not protrude outside.
For at gribefligen 5 ikke ved afrivning af båndet 1 skal kunne glide af ved dettes afrivningsende 6, må afrivningsenden 6, som det er vist i fig. 2a, fortrinsvis på et sted foran gribefligen 5 have en 35 hage 7, der kan udstanses samtidig med udsparingen 3.In order for the gripping tab 5 not to slip off at the tear-off end 6 of the strip 1, the tear-off end 6, as shown in FIG. 2a, preferably at a location in front of the gripping tab 5, has a 35 hook 7 which can be punched out at the same time as the recess 3.
Det samme formål kan ifølge fig. 2b også opnås ved, atAccording to FIG. 2b is also obtained by the fact that
OISLAND
5 14577$ afrivningsenden 6 ved gribefligen 5 har en opad eller udad rettet holdeknast 8. Denne holdeknast kan også være anbragt i midten af en af et klæbebånd bestående gribeflig, især når der i klæbebåndets midte findes en 5 forstærkningstråd, der kan fastholdes i denne holdeknast.The tear-off end 6 of the gripping tab 5 has an upwardly or outwardly directed retaining knob 8. This retaining knob may also be positioned in the center of a gripping tab, particularly when in the center of the adhesive tape there is a reinforcing thread which can be held in this retaining knob. .
Ifølge yderligere en udførelsesform for opfindelsen består gribefligen 5 af en plast- eller metalfolie, der er sammensvejset eller sammennittet i udsparingen 3.According to a further embodiment of the invention, the gripping tab 5 consists of a plastic or metal foil welded or joined together in the recess 3.
Fig. 4 viser en sådan udførelsesform, ved hvilken 10 gribelfigen 5 består af metal, fortrinsvis et letmetal, og fastholdes i en fordybning 13 i dækpladen 12.FIG. 4 shows such an embodiment in which the gripper fig 5 consists of metal, preferably a light metal, and is held in a recess 13 in the cover plate 12.
Fastholdelsen kan ske på kendt måde f.eks. ved, at den yderste ende af gribefligen er udformet som en Øsken, der fastholdes i en knaplignende holdeindretning i 15 fordybningen 13 i dækpladen 12. Gribefligen 5 er ved denne udførelsesform ved 14 sammensnittet med sig selv i udsparingen 3.The retention can be done in a known manner e.g. in that the outer end of the gripping tab is formed as a box which is held in a button-like holding device in the recess 13 in the cover plate 12. The gripping tab 5 in this embodiment at 14 is the member with itself in the recess 3.
Svækkelseslinien 2 ligger efter lukning af beholderen fortrinsvis under beholderhalsvulsten eller mundingsringen.The line of weakening 2, after closure of the container, is preferably below the container neck bead or mouth ring.
20 Derved opnås, at dækslet efter afrivning af den nedre rand 1 fortsat kan anvendes som løst påsiddende dæksel for at forhindre, at der trænger støv ind i beholderens indre. Dette er f.eks. meget ønskeligt, når beholderen indeholder et børnenæringsmiddel. Den efter afrivning af afrivnings-25 strimlen 1 tilbageblivende, noget indadbøjede kant på det genanvendelige dæksel griber ved fornyet lukning ind i den tilsvarende indsnøring under beholderhalsvulsten eller mundingsringen.In this way it is achieved that, after tearing off the lower edge 1, the cover can still be used as a loose-fitting cover to prevent dust from entering the interior of the container. This is e.g. highly desirable when the container contains a child nutrient. The remaining, slightly inwardly curved edge of the reusable cover, after tearing off the tear strip 1, engages again in the corresponding lacing under the container neck or mouth ring.
I fig. 6 er vist, at der med oprivningsdækslet 30 ifølge opfindelsen, udover enhver sædvanlig beholder med mindst én beholderhalsvulst og derover i givet fald også gevind, også kan lukkes beholdere, der har en gennemgående ensartet vægtykkelse i beholderhalsen, og ved hvilke mundingen kun er afbøjet vinkelret udad 35 foroven.In FIG. 6, it is shown that with the tear-off cover 30 according to the invention, in addition to any usual container with at least one container neck bead and, where applicable, threads can also be closed, having a uniform uniform wall thickness in the container neck, at which the mouth is only deflected perpendicularly outwards 35 above.
