(54) Låg til beholdere for flydende indhold.(54) Liquid content container lids.
Den foreliggende opfindelse angår et låg til beholdere for flydende indhold med en udtømningsåbning og en ud-luftningsåbning, som på den fra beholderens indre bortvendende side af låget er lukket ved hjælp af en med låget forbundet, let afrivelig foliestrimmel.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for liquid contents having a discharge orifice and a vent orifice which is closed on the inner side of the container which is facing away from the container by means of an easily removable film strip.
Til beholdere for flydende indhold, som f.eks. drikke eller olie, kendes der hovedsagelig to lågudformninger.For liquid content containers, such as drink or oil, there are mainly two lid designs known.
00
De adskiller sig ved, at låget ved den ene udformning er for-Γ) synet med organer til dannelse af en kombineret udtømnings- og ^ udluftningsåbning, medens der ved den anden udformning findes f forud i låget udførte åbninger, som er lukket ved hjælp af en tildækning. Den første udformning foretrækkes ved beholderind- t i 145453 2 hold, der står under tryk, hvorimod den anden udformning anvendes til indhold, der ikke står under tryk.They differ in that, in one embodiment, the lid is provided with means for forming a combined discharge and vent opening, while in the other embodiment there are pre-formed openings closed by means of the lid. a cover. The first design is preferred for container pressures in pressurized holders, whereas the second design is used for non-pressurized contents.
Organerne til udskæring af en kombineret udtømnings- og udluftningsåbning i beholderens låg består af en vægtstangsarm, der er således udformet, at løftning af den ene ende af armen bevirker, at den anden ende af armen presses mod låget på en sådan måde, at åbningen automatisk udskæres. Ved en anden udførelsesform af denne type udrives ved hjælp af passende udformning af armen en åbning i låget. Ved beholderindhold, som er tilbøjelige ±il at fordærves under tilgang af luft, vender en forbruger ved erhvervelsen af dåsen særlig sin opmærksomhed mod, at beholdertillukningen er intakt, hvilket giver forbrugeren sikkerhed for, at indholdet i beholderen er ufordærvet.The means for cutting a combined discharge and vent opening in the lid of the container consists of a lever arm which is designed such that lifting one end of the arm causes the other end of the arm to be pressed against the lid in such a way that the opening automatically cut. In another embodiment of this type, an opening in the lid is effected by means of a suitable design of the arm. For container contents that are prone to perish during the supply of air, a consumer, when acquiring the can, pays particular attention to the container closure being intact, giving the consumer assurance that the contents of the container are undamaged.
Denne kontrol udføres meget let ved behodderlåg med en opriv-ningsarm. Således forholder det sig imidlertid ikke ved låg, hvis forudfremstillede udtømnings- og udluftningsåbninger er lukket med en tildækning af folie. Tildækningen klæbes til låget, og en overlagt eller tilfældig beskadigelse af forbindelsen mellem tildækningen og låget under blotlæggelse af åbningen forbliver for det meste skjult for en forbruger.This check is carried out very easily by the container lid with a tear-off arm. However, this does not apply to lids whose pre-made discharge and vent openings are closed with a film cover. The cover is adhered to the lid, and any deliberate or accidental damage to the connection between the cover and the lid while exposing the opening remains mostly hidden from a consumer.
Det er den foreliggende opfindelses opgave at tilvejebringe et låg af den indledningsvis angivne art, som muliggør en simpel kontrol af forekommende beskadigelser af forbindelsen pellem foliestrimmelen og beholderlåget, og denne opgave løses ifølge opfindelsen ved, at folie strimmelen er forsynet med en svækningslinie, der er således udformet, at den ved oprivning af foliestrimmelen vil opdele denne i fra hinanden adskillelige delstykker. En simpel betragtning af foliestrimmelen vil derfor vise, om der er gjort forsøg på at fjerne den.It is the object of the present invention to provide a lid of the kind initially provided which allows for a simple check of any damage to the connection between the foil strip and the container lid, and this problem is solved according to the invention by providing the foil strip with a line of weakness which is so designed that, when tearing up the film strip, it will divide it into separable sections. A simple look at the foil strip will therefore show whether attempts have been made to remove it.
En særlig udførelsesform ifølge opfindelsen består i, at svækningslinien forløber under en vinkel i forhold til foliestrimmelens langsider. Svækningslinien og dermed afrivningsvejen forlænges ganske vist noget med vinklen, men det har imidlertid vist sig, at der herved lettere opnås en fejlfri afrivning. En videre udformning ifølge opfindelsen er karakteriseret ved, at svækningslinien på begge sider udmunder i en udsparing. Ved udsparingerne koncentreres manipulationerne med foliestrimmelen endnu mere til svækningslinierne. Endvidere letter udsparingen løftningen af en del af foliestrimmelen før afrivning langs svækningslinien og dannelsen af trækflige.A particular embodiment of the invention consists in the line of weakening extending at an angle to the long sides of the foil strip. The line of weakening and thus the tear-off path is somewhat extended by the angle, but it has been found, however, that easier to achieve a flawless tear-off. A further embodiment of the invention is characterized in that the line of weakening on both sides opens into a recess. In the recesses, the manipulations with the foil strip concentrate even more on the lines of weakness. Furthermore, the recess facilitates the lifting of a portion of the foil strip before tearing along the line of weakening and the formation of pull tabs.
145453 3145453 3
En videre fordelagtig udformning ifølge opfindelsen er karakteriseret ved, at der i foliestrimmelen på begge sider af svækningslinien findes et med låget uforbundet område.A further advantageous design according to the invention is characterized in that in the foil strip on both sides of the weakening line there is an area with a lid which is not connected.
Herved tydeliggøres endnu mere beskadigelser ved svækningslinien, da afrevne delstykker, f.eks. langs en knæklinie i en foliestrintr meldel eller ved en oprulning af det uforbundne modsat liggende delstykke, tydeligt synliggøres. løvrigt lettes ved denne udførelsesfonn adskillelsen langs svækningslinien ved, at man ikke skal overvinde forbindelsesmodstanden mellem foliestrimmelen og låget.This further clarifies further damage at the line of weakness, as torn pieces, e.g. along a crack line in a foil step mill or by a roll-up of the unconnected opposite piece, is clearly visible. In this embodiment, the separation along the line of weakening is facilitated by not having to overcome the connection resistance between the foil strip and the lid.
En udførelsesform ifølge opfindelsen beskrives nærmere i det følgende under henvisning til tegningen, hvor fig.l viser et låg med en foliestrimmel ifølge opfindelsen og fig.2 samme set fra siden i snit.An embodiment of the invention is described in more detail below with reference to the drawing, in which: Figure 1 shows a lid with a foil strip according to the invention and Figure 2 shows the same side view in section.
Pig.l viser eksempelvis et ifølge opfindelsen . udformet låg til en rund beholder. Låget kan imidlertid også være tilpasset til beholdere med anden udformning. Til tømning af beholderens indhold omfatter låget 10 en udtømningsåbning 11 og en udluftningsåbning 12. Udtømningsåbningen 11 og udluftnings-åbningen 12 er lukket ved hjælp af en foliestrimmel 13, som ved brug af beholderens indhold afrives fra låget 10.Fig. 1 shows, for example, one according to the invention. designed lid for a round container. However, the lid may also be adapted for containers of a different design. For emptying the contents of the container, the lid 10 comprises a discharge opening 11 and a vent opening 12. The discharge opening 11 and the vent opening 12 are closed by a film strip 13 which, using the contents of the container, is torn off the lid 10.
I afhængighed af indholdet kan låget og foliestrimmelen såvel som beholderen være fremstillet af forskelligartede ikke-metalliske og metalliske materialer. Endvidere kan der anvendes forskellige materialekombinationer mellem låg og foliestrimmel. Det er dog foretrukket at fremstille låg og foliestrimmel af et metallisk materiale, navnlig aluminium eller en aluminiumlegering.Depending on the contents, the lid and foil strip as well as the container may be made of various non-metallic and metallic materials. Furthermore, different material combinations between lids and foil strip can be used. However, it is preferred to make lids and foil strips of a metallic material, in particular aluminum or aluminum alloy.
Forbindelsen af foliestrimmel og låg kan bl.a. tilvejebringes ved påføring af et klæbemiddel. Hvis låget og foliestrimmelen består af metal, må der forud for tilklæbningen ske en forbehandling af metalfladerne, der skal bringes i indgreb, for at forbedre sammenhæftningen. Forbehandlingen omfatter påføring af hæftemidler, eller der sker i tilfælde af, at låget består af aluminium, en særlig, kemisk behandling af overfladerne.The connection of foil strip and lids can ia. is provided by application of an adhesive. If the lid and foil strip are made of metal, prior to the adhesive, a pre-treatment of the metal surfaces to be engaged must be done to improve the adhesion. The pre-treatment involves the application of adhesives or, in the event that the lid is made of aluminum, a special chemical treatment of the surfaces.
Det har vist sig særligt gunstigt at overtrække foliestrimmelen med et påsmelteligt formstoflag, og forbin- 145453 4 delsen tilvejebringes ved hjælp af en ydre energipåvirkning, som påsmelter formstoflaget, hvorved forbindelsen er fuldt tilvejebragt efter størkning af formstoflaget. Sirligt hensigtsmæssige påsmeltelige formstoffer til løsning af opgaven ifølge opfindelsen er polyvinylchlorid, polyolefin, en ionomer copolymer af ethylen, en copolymer med et ioniserende metalcarboxylat af ethylen, en med acrylsyre podet polymer af ethylen og en polyamid af dimere fedtsyrer. Skal beholderen undergå en sterilisation, foretrækkes som påsmelteligt formstof en med acrylsyre podet polymer af ethylen eller en polyamid.It has been found particularly advantageous to coat the foil strip with a fusible plastic layer and the connection is provided by an external energy influence which fuses the plastic layer, whereby the compound is fully formed after solidification of the plastic layer. Particularly suitable fusible resins for solving the task of the invention are polyvinyl chloride, polyolefin, an ionomeric copolymer of ethylene, a copolymer with an ionizing metal carboxylate of ethylene, an acrylic acid grafted polymer of ethylene and a polyamide of dimeric fatty acids. If the container is to undergo sterilization, as a fusible plastic, an ethylene or polyamide grafted with acrylic acid is preferred.
Ved en af aluminium bestående foliestrimmel påføres hensigtsmæssigt formstof med en tykkelse på 0,01-0,1 mm på foliestrimmelen, hvorhos tykkelsen af foliestrimmelen kan andrage 0,02-0,35 mm. Formstoflagets tykkelse og foliestrimmelens tykkelse afpasses efter hinanden med henblik på en af indholdet betinget styrke af forbindelsen mellem låg og foliestrimmel .Suitably, a foil strip of aluminum having a thickness of 0.01-0.1 mm is applied to the foil strip, the thickness of the foil strip being 0.02-0.35 mm. The thickness of the plastic layer and the thickness of the foil strip are matched to one another for the strength of the content of the connection between the lid and the foil strip.
En påsmeltning af formstoflaget 14 sker under ydre energipåvirkning på laget ik. Som egnet har herved vist sig den såkaldte forsegling, ved hvilken foliestrimmelen 13 samtidigt påvirkes af varme og tryk. Endvidere kan forbindelsen •gså tilvejebringes ved hjælp af den såkaldte ultralydsvejsning, højfrekvenssvejsning eller ved hjælp af den såkaldte varmeim-pulsfremgangsmåde.A melting of the plastic layer 14 takes place under external energy influence on the layer IC. As is suitable hereby, the so-called seal has been found, at which the film strip 13 is simultaneously affected by heat and pressure. Furthermore, the connection can also be provided by the so-called ultrasonic welding, high frequency welding or by the so-called heat pulse method.
Fordelen ved disse formstoffer i forbindelse med den særlige forbindelsesteknik ligger i, at metalliske klæbeflader ikke som ved anvendelse af klæbestoffer skal underkastes en forbehandling til forbedring af vedhæftningen.The advantage of these plastics in connection with the particular bonding technique lies in the fact that metallic adhesive surfaces do not, as with adhesives, be subjected to a pretreatment to improve the adhesion.
Omkring låget 10*s omkreds forløber en bertlet rand 19, som til forbindelse af låget 10 med en ikke vist beholder bringes i indgreb med tilsvarende ansatser på beholderens frie omkredsrand og herefter sammenrulles.Around the circumference of the lid 10 *, a curved edge 19 extends, which, in connection with the lid 10 with a container not shown, is engaged with corresponding abutments on the free circumferential edge of the container and then rolled.
Til beskyttelse af indholdets originalitet er foliestrimmelen 13 udrustet med en svækningslinie 15, som forløber mellem foliestrimmelen 13’s længdesider. Svækningslinien består af ved siden af hinanden anbragte huller i folie strimmelen 13, idet man lader mellemrummene, der forbliver mellem hullerne, stå. I det foreliggende tilfælde forløber svækningslinien 15 under en vinkel på ^5° i forhold til folie strimmelenTo protect the originality of the content, the foil strip 13 is provided with a weakening line 15 extending between the long sides of the foil strip 13. The line of weakening consists of adjacent holes in the foil strip 13, leaving the spaces remaining between the holes. In the present case, the weakening line 15 extends at an angle of 5 ° to the foil strip
