Opfindelsen angår et beholderlåg af elastisk deformerbart plast og med en lågflange, der er indrettet til at gribe omkring mundingsranden af en beholder, idet den har en indadret-tet rundtgående låseribbe, som kan gribe ind under en udven-5 dig perifer vulst eller flange på mundingsranden.The invention relates to a container lid of elastically deformable plastic and with a lid flange adapted to grip around the mouth of a container, having an inwardly extending locking rib which can engage under an outer peripheral bead or flange of the rim.

Låg af den art, der anvendes til tætsluttende lukning af beholdere f.eks. malingbøtter, er ofte temmelig besværlige at aftage, idet en effektiv tætning forudsætter en kraftig forspænding af materialet i det på beholderen anbragte låg.Lids of the kind used for tightly closing containers e.g. paint buckets, are often rather cumbersome to remove, since an effective seal requires a strong biasing of the material in the lid applied to the container.

10 Formålet med opfindelsen er, at gøre det lettere, at aftage et sådant på en beholder stramt siddende låg, og dette er ifølge opfindelsen opnået ved at lågflangen ved låseribben går over i en rundtgående løsneflange, som danner en bistabil snaplås, idet den er ombukkelig mellem en nedadrettet stilling, 15 i hvilken låseribben under spænding kan ligge an mod beholderens vulst eller flange, og en opadrettet udløserstilling, i hvilken låseribben går fri af beholderens vulst eller flange eller ligger an mod denne under reduceret spænding.The object of the invention is to facilitate the removal of such a lid on a container tightly seated lid, and this is achieved according to the invention by the lid flange at the locking rib changing into a circumferential release flange which forms a bistable snap-lock, being flexible. between a downward position, in which the locking rib under tension can abut against the bead or flange of the container, and an upwardly released release position in which the locking rib protrudes from the bead or flange of the container or abuts against it under reduced tension.

Lågflangen og løsneflangen danner leddene i et bistabilt 20 knæled, idet partiet mellem de to flanger udgør en hængselforbindelse, og ringspændingen i løsneflangen virker som en fjeder, der i flangens ene stilling medvirker til at holde låseribben i fast indgreb med vulsten eller flangen på beholderen, og i den anden stilling holder låseribben fri af 25 eller kun i let forbindelse med beholderflangen eller -vulsten. Brugeren af beholderen kan let ved at føre fingrene rundt langs undersiden af løsneflangen bringe denne hen i en udsvinget stilling, hvor ringspændingen er maksimal, således at løsneflangen snapper op i udløserstilling. Her-30 efter kan låget uden vanskelighed aftages, og under brug af * beholderen kan det sættes løst på denne, når indholdet midlertidigt ønskes dækket.The cover flange and the release flange form the joints of a bistable knee joint, the portion between the two flanges forming a hinge connection and the ring tension in the release flange acting as a spring which in one position of the flange contributes to holding the locking rib in firm engagement with the bead or flange of the container. and in the second position, the locking rib holds free of 25 or only in light connection with the container flange or bead. The user of the container can easily move the fingers along the underside of the release flange to a pivoted position where the ring tension is maximal, so that the release flange snaps into release position. Thereafter, the lid can be easily removed and, using the * container, it can be released loosely when the contents are temporarily covered.

En udførelsesform for beholderlukket ifølge opfindelsen er ejendommelig ved en over låseribben på indersiden af 35 lågflangen dannet, rundtgående udsparing, som danner et tyndt bøjeligt parti i lågflangen umiddelbart over låseribben. Denneudformning er især anvendelig vedAn embodiment of the container lid according to the invention is characterized by a circular recess formed over the locking rib on the inside of the lid flange, which forms a thin flexible portion of the lid flange immediately above the locking rib. This design is particularly useful for

145194 2 aksialt forspændte låg,hvis underside langs en smal tætnings-linie slutter tæt til beholderens mundingskant,og hvis låg-flange er anbragt i radial afstand uden for denne og med et skarpt knæk går over i selve lågfladen uden mulighed for 5 overføring af et bøjningsmoment. Et sådant låg er forspændt i aksial retning ved at afstanden mellem beholderens mundingskant og undersiden af beholderflangen eller vulsten er større end den vertikale afstand mellem lågets tætningslinie og oversiden af låseribben på lågflangen i det ikke 10 påsatte låg. Ved påsætning af låget opstår der i lågflangen en kraftig aksial spænding, som er desto større jo kraftige-’ re tryk pr. fladeenhed, der ønskes ved tætningslinien mellem beholderens mundingskant og låget. Da lågflangen kun står under aksial forspænding og altså kun under trækpåvirkning, 15 kan overgangspartiet mellem lågflangen og løsneflangen gøres relativt tyndvægget, således at ombukningen af løsneflangen fra den ene stilling til den anden stort set kun kræver overvindelse af den maksimale ringspænding i løsneflangen.Axially prestressed lids whose underside along a narrow sealing line joins close to the mouth of the container and whose lid flange is spaced radially away from it and with a sharp crack passes into the lid surface itself without the possibility of transferring a bending moment. Such a lid is biased axially in that the distance between the mouth of the container and the underside of the container flange or bead is greater than the vertical distance between the lid sealing line and the upper side of the locking rib of the lid flange in the non-applied lid. When the lid is applied, a strong axial tension is created in the lid flange, which is the greater the stronger the pressure per surface assembly desired at the sealing line between the mouth of the container and the lid. Since the lid flange is only under axial bias and thus only under tensile stress, the transition portion between the lid flange and the release flange can be made relatively thin-walled, so that the bending of the release flange from one position to the other only requires the overcoming of the maximum annular tension in the release flange.

Ved beholderlåg beregnet til tætning ved aksial for-20 spænding alene er det af mindre betydning om ringspændingen i låset stilling eller i udløserstilling er størst, og løsneflangen kan derfor i låsestillingen strække sig i hovedsagen lodret ned langs beholdersiden, således at den ikke er i vejen, når flere beholdere er anbragt ved siden af hin-25 anden. Ved andre beholdere f.eks. marmeladekrukker og lignende ;beholdere med udadhvælvede sider under mundingskanten kan løsneflangen ifølge opfindelsen være udformet således,at dens diameter er større i låsestilling end i udløserstilling, hvorved ringspændingen i flangen er størst i låsestil-30 ling, hvilket især har betydning ved de lågtyper, hvor tætningen mellem en mundingsvulst og beholderlåget er baseret på forspænding i radial retning.In container lids intended for sealing at axial tension alone, it is of minor importance whether the ring tension in the locked or release position is greatest, and the release flange can therefore extend in the locking position substantially vertically down the container side so that it is not in the way. when several containers are placed next to each other. For other containers e.g. jam jars and the like; containers with outwardly arched sides below the mouth edge, the release flange according to the invention may be designed such that its diameter is greater in the locking position than in the release position, whereby the ring tension in the flange is greatest in the locking position, which is especially important in the lid types, where the seal between an orifice and the container lid is based on radial biasing.

Opfindelsen forklares nærmere i det følgende i forbindelse med tegningen hvor 35The invention will be further explained in the following in connection with the drawing wherein 35

3 145194 fig. 1 og 2 viser en udførelsesform for beholderlåget ifølge opfindelsen henholdsvis i et radialt delsnit og set ovenfra, fig. 3 et delsnit gennem en foretrukken udførelsesform 5 for beholderlåget ifølge opfindelsen og fig. 4 et tilsvarende delsnit gennem en anden udførelsesform for beholderlåget ifølge opfindelsen.FIG. 1 and 2 show an embodiment of the container lid according to the invention in a radial sectional view, respectively, from above; 3 is a partial section through a preferred embodiment 5 of the container lid according to the invention; and FIG. 4 shows a similar partial section through another embodiment of the container lid according to the invention.

Det i fig. 1-3 viste beholderlåg har en plan lågflade 1 og en i hovedsagen aksial, under brug nedadrettet 10 lågflange 2, som over et konisk randparti 3 går over i et radialt flangeparti 4, der er forbundet med lågfladen 1 gennem et i hovedsagen aksialt, indre flangeparti 5. På undersiden af det radiale flangeparti 4 findes en aksial styreribbe 6 og en skarp tætningskant 7, som ligger an mod 15 mundingskanten af en beholder langs en smal tætningslinie.The FIG. 1-3, a lid lid 1 has a flat lid surface 1 and a generally axial, downwardly used lid flange 2, which overlies a conical rim portion 3 into a radial flange portion 4 which is connected to the lid surface 1 through a generally axial inner surface. flange portion 5. On the underside of the radial flange portion 4 there is an axial guide rib 6 and a sharp sealing edge 7 which abuts the mouth edge of a container along a narrow sealing line.

I lågets påsatte, tætlukkede stilling ligger en rundtgående låseribbe 8 indvendigt på lågflangen 2 an mod en nedadvendende låsekant yderst på en ringformet beholderflange 9, san strækker sig ud fra beholderens væg 10. I fig. 3 er med punkterede linier antydet 20 stillingen af det koniske randparti 3, når låget er anbragt løst oven på beholderen. I denne stilling er den vertikale afstand mellem beholderens mundingskant og den nedadvendende låsekant på beholderflangen 9 større end den vertikale afstand mellem tætningskanten 7 og oversiden af låseribben 8.In the lid's closed, closed position, a circumferential locking rib 8 lies internally on the lid flange 2 against a downwardly extending locking edge at the outer end of an annular container flange 9 extending from the wall of the container 10. In FIG. 3 is indicated by dotted lines 20 the position of the tapered edge portion 3 when the lid is loosely placed on top of the container. In this position, the vertical distance between the mouth edge of the container and the downward locking edge of the container flange 9 is greater than the vertical distance between the sealing edge 7 and the upper side of the locking rib 8.

25 Når låget er tætsluttende anbragt på beholderen, er det koniske randparti 3, som vist med fuldt optrukne linier presset nedad ved et tryk i aksial retning, hvorved låseribben 8 er bragt til at gribe ind under låsekanten på beholderflangen 9. Herved er låseflangen 2 påvirket af en 30 aksial trækspænding, som bevirker at tætningskanten 7 er presset hårdt ned mod beholdermundingen.When the lid is sealed tightly on the container, the tapered rim portion 3, as shown in fully drawn lines, is pressed downwardly at an axial pressure, whereby the locking rib 8 is brought into engagement under the locking edge of the container flange 9. Thus, the locking flange 2 is affected. of an axial tensile tension which causes the sealing edge 7 to be pressed down hard against the container mouth.

Umiddelbart over låseribben 8 har lågflangen 2 en rundtgående udsparing 11, således at der dannes et tyndvægget parti 12. Det tyndvæggede parti forbinder lågflangen 2 med 35 en løsneflange 13, som i lukkestillingen står i den viste nedadrettede stilling.Immediately above the locking rib 8, the lid flange 2 has a circumferential recess 11 so as to form a thin-walled portion 12. The thin-walled portion connects the lid flange 2 with a release flange 13, which in the closing position is in the downward position shown.

4 fΛ519Λ Når en bruger af beholderen ønsker at aftage låget, fører han fingrene rundt langs underkanten af løsneflangen 13 under udøvelse af et udad- og opadgående træk, hvorved ringspændingen i flangen forøges til en maksimal værdi, hvorefter 5 flangen pludselig smækker op i den med punkterede linier viste stilling,hvor låseribben 8 går fri af beholderflangen 9. Løsneflangen 13 virker således som et bistabilt knæled, der langs det tyndvæggede parti 12 er hængselforbundet med lågflangen 2 og er fastholdt i sine yderstillinger under påvirk-lo ning af ringspændingen i fligen. Ved at udforme løsnefligen 13 således, at den i lukkestilling strækker sig længere ud fra beholderen i radial retning, kan som følge af den forøgede ringspænding opnås et endnu fastere greb mellem låseribben 8 og beholderflangen 9.4 fΛ519Λ When a user of the container wants to remove the lid, he moves his fingers along the lower edge of the release flange 13, in the case of an outward and upward pull, thereby increasing the ring tension in the flange to a maximum value and then the flange suddenly opens up into it with dotted lines show a position in which the locking rib 8 is released from the container flange 9. The release flange 13 thus acts as a bistable knee joint, which along the thin-walled portion 12 is hingedly connected to the lid flange 2 and is held in its outer positions under the influence of the ring tension in the tab. By forming the release tab 13 such that in the closing position it extends farther from the container in the radial direction, due to the increased ring tension, an even firmer grip can be obtained between the locking rib 8 and the container flange 9.

15 Dette er især ønskeligt når tætningen mellem beholder munding og låg beror på radial forspænding af låget, således som det er tilfældet ved den i fig. 4 viste udførelsesform.This is particularly desirable when the seal between container mouth and lid is due to radial biasing of the lid, as is the case in the embodiment shown in FIG. 4.

Her går den plane lågflade 1 direkte over i en aksial lågflange 14, som på indersiden har en låseribbe 15 i form af 20 en rundtgående vulst, der i lågets tætsluttende stilling griber ind under en mundingsvulst 16 øverst på beholderens væg 10. Løsneflangen 13 har som vist en større diameter i lukkestilling end i udløst stilling, således at låseribben 14 i lukkestillingen presses stramt ind omkring mundings-25 vulsten 16, medens den i løsneflangens opsvingede stilling, der er vist med punkterede linier, i hovedsagen går fri af mundingsvulsten 16. Eventuelt ligger låseribben 14 i udløserstilling stadig an mod mundingsvulsten 16 men med et mindre tryk, således at den let kan passere mundingsvulsten 16, når 30 låget trækkes af.Here, the planar lid surface 1 passes directly into an axial lid flange 14, which on the inside has a locking rib 15 in the form of 20 a circumferential bead which engages in the tightly closed position of the lid under an orifice bead 16 at the top of the container wall 10. The release flange 13 has as shown a larger diameter in the closing position than in the released position, so that the locking rib 14 in the closing position is pressed tightly around the orifice bead 16, while in the flared position of the release flange, shown in dotted lines, substantially free of the orifice bead 16. Optionally, For example, the locking rib 14 in the release position still abuts against the mouth bead 16 but with a smaller pressure, so that it can easily pass through the mouth bead 16 when the lid is pulled off.

Ligeledes er det heller ikke absolut nødvendigt,at låseribben i udførelsesformen i fig. 3 går helt fri af beholderflangen 9; når låget aftages eller påsættes.Also, it is not absolutely necessary that in the embodiment of FIG. 3 is completely free of container flange 9; when removing or applying the lid.

Beholderlåget ifølge opfindelsen med den som bistabil snap-35 lås virkende løsneflange kan tænkes udformet på andre måder end de her viste. Specielt kan beholderlåget være udformet således,at dets periferi i hovedsagen har form som en regulærThe container lid according to the invention with the detachable flange acting as a bistable snap-lock can be conceived in ways other than those shown here. In particular, the container lid may be formed such that its periphery is substantially in the form of a regular
