Description
Foreliggende oppfinnelse vedrører e,t snepperthengsel i ett stykke, av plastmateriale med kjennetegn som angitt i den innledende del av krav 1. Ved slike snepperthengsler er leddene som dels forbinder de to hengseldeler med hverandre og dels forbinder det fjærende mellomstykke med de to hengseldeler, dannet av filmhengselpartier av plastmaterialet. Av hensyn til det store antall åpne- og lukkebevegelser som et slikt snepperthengsel må kunne tåle i løpet av sin brukstid, f.eks. ved anvendelse som flaskekapsel, har slike snepperthengsler hittil bare kunnet fremstilles av polypropylen. For andre plastmaterialer har på-kjenningene vist seg for store. The present invention relates to a snap hinge in one piece, made of plastic material with characteristics as stated in the introductory part of claim 1. In such snap hinges, the joints that partly connect the two hinge parts to each other and partly connect the springy intermediate piece to the two hinge parts are formed of film hinge parts of the plastic material. Due to the large number of opening and closing movements that such a snap hinge must be able to withstand during its service life, e.g. when used as a bottle cap, such snap hinges have so far only been able to be produced from polypropylene. For other plastic materials, the effects have proven to be too great.
Snepperthengsler av denne type finner hovedsakelig anvendelse som lukkekapsler for flasker og beholdere. Propylen er relativt hardt. Hvis det, for avtetting mot munningen av en flaske av sprøtt materiale såsom glass eller polyvinylklorid, benyttes en tetningskonus som er utformet i ett med lukkekapselen, er det risiko for at flaskemunningen vil sprenges når kapselen påskrues. Det er derfor ønskelig å kunne fremstille lukkekapsler med snepperthengsler av et mykere materiale enn polypropylen, uten at smekkvirkningen forringes. Snap hinges of this type are mainly used as closures for bottles and containers. Propylene is relatively hard. If, for sealing against the mouth of a bottle made of brittle material such as glass or polyvinyl chloride, a sealing cone is used which is designed in one with the closing capsule, there is a risk that the bottle mouth will explode when the capsule is screwed on. It is therefore desirable to be able to produce closures with snap hinges from a softer material than polypropylene, without the snap action being impaired.
Lukkekapsler av polypropylen kan ikke anvendes i forbindelse med uttømming av vilkårlige fyllstoffer, da polypropylen bare er betinget bestandig overfor bestemte fyllstoffgrupper, eksempelvis aromatiske kullvannstoffer. Sealing caps made of polypropylene cannot be used in connection with emptying arbitrary fillers, as polypropylene is only conditionally resistant to specific filler groups, for example aromatic coal water substances.
Det har lenge vært et ønske å kunne fremstille snepperthengsler for lukkekapsler, skjenketuter og lignende, som er forenlige med de ovennevnte og andre stoffer, særlig slike som ikke må komme i berøring med polypropylen. It has long been a desire to be able to produce snapper hinges for closures, pouring spouts and the like, which are compatible with the above and other substances, especially those which must not come into contact with polypropylene.
Hovedformålet ved oppfinnelsen er å frembringe et snepperthengsel i ett stykke av plastmateriale som har egenskaper som angitt i den innledende del av krav 1, og som er mykere og med et annet kompatibilitetsområde enn polypropylen. The main purpose of the invention is to produce a snap hinge in one piece of plastic material which has properties as stated in the introductory part of claim 1, and which is softer and with a different compatibility range than polypropylene.
Dette er oppnådd som definert i krav 1. Det har overras-kende vist seg at lavtetthets-polyetylen (low density polyethylen) kan tåle et stort antall bøyebevegelser dersom det, istedenfor de hittil vanlige filmhengsler, anvendes et bånd av polyetylen med en lengde som er større enn båndtykkelsen. Båndene må følge-lig være vesentlig lengre enn de kjente filmhengsler. This has been achieved as defined in claim 1. It has surprisingly been shown that low density polyethylene can withstand a large number of bending movements if, instead of the hitherto usual film hinges, a strip of polyethylene is used with a length that is greater than the tape thickness. The bands must therefore be significantly longer than the known film hinges.
Hovedtypen av slike snepperthengsler omfatter et hovedledd bestående av to seksjoner som er innbyrdes forskjøvet langs leddaksen, med et enkelt, mellomliggende forbindelsesstykke. Det kan imidlertid anvendes omvendt anordning med et relativt bredt hovedledd som på begge sider går over i to fjærende forbindelsesstyk-ker. The main type of such snapper hinges comprises a main link consisting of two sections which are mutually offset along the joint axis, with a single, intermediate connecting piece. However, the reverse device can be used with a relatively wide main joint which on both sides merges into two springy connecting pieces.
Det var ikke nærliggende å utforme et ledd som bånd, da det derved ikke lenger ville defineres en nøyaktig leddakse. Det har imidlertid vist seg at smekkfunksjonen ikke påvirkes ugunstig, på tross av en viss labilitet i hovedleddet. Det vil, likesom tid-ligere, opprettholdes en åpen-stilling og en lukket-stilling, og i den ene eller den annen av .disse vil hengseldelene på begge sider av seg selv innsmekke i en labil likevektsstilling som de bibeholder automatisk. It was not obvious to design a joint as a band, as a precise joint axis would no longer be defined thereby. However, it has been shown that the snap function is not adversely affected, despite a certain lability in the main joint. An open position and a closed position will be maintained, just like time-ligers, and in one or the other of these, the hinge parts on both sides of themselves will snap into a labile equilibrium position which they maintain automatically.
Mens hovedleddet i de fleste anvendelsestilfeller må gjennom-løpe en dreievinkel av ca. 180°, behøver sideleddene bare å gjen-nomføre en dreining av ca. 90°. Utformingen og varighetsbelast-barheten av sideleddene er derfor mindre kritisk. Ved en modifisert versjon ifølge krav 2, kan imidlertid sideleddene også være utformet som bånd, hvorved det oppnås en større varighets-belastbarhet av snepperthengslet i dets helhet. While the main link in most cases of application must go through a turning angle of approx. 180°, the side joints only need to complete a turn of approx. 90°. The design and durability of the side joints is therefore less critical. In a modified version according to claim 2, however, the side links can also be designed as bands, whereby a greater durability loadability of the snap hinge as a whole is achieved.
Det er oppnådd gode resultater med en modifisert versjon ifølge krav 3, med et bestemt forhold mellom båndlengden og båndtykkelsen. Good results have been achieved with a modified version according to claim 3, with a specific ratio between the tape length and the tape thickness.
Oppfinnelsen er nærmere beskrevet i det etterfølgende under henvisning til de medfølgende tegninger, hvor: Fig. 1 viser et delsnitt, på tvers av leddaksen, av et snepperthengsel ifølge oppfinnelsen. Fig. 2 viser et tilsvarende delsnitt av et snepperthengsel av kjent type. Fig. 3 og 4 viser perspektivriss av kjente snepperthengsel-lokk som kan utstyres med hoved- og sideledd i overensstemmelse med foreliggende oppfinnelse. The invention is described in more detail below with reference to the accompanying drawings, where: Fig. 1 shows a partial section, across the joint axis, of a snap hinge according to the invention. Fig. 2 shows a corresponding partial section of a snap hinge of a known type. Figs 3 and 4 show perspective views of known snap hinge lids which can be equipped with main and side joints in accordance with the present invention.
Hvert snepperthengseldeksel omfatter en underdel 2 og et lokk 4. Delene er forbundet med hverandre gjennom et hovedledd 6 som, ifølge fig. 3, innbefatter to hovedleddseksjoner 6a og 6b langs hovedaksen. Et elastisk forbindelsesstykke 8 i form av en vinkelbøyd bøyefjær er, som vist i fig. 3, anordnet mellom de to hovedleddseksjoner 6a og 6b. Gjennom sideledd 10 og 12 er for-bindelsesstykket forbundet med henholdsvis underdelen-2 og Each snap hinge cover comprises a lower part 2 and a lid 4. The parts are connected to each other through a main joint 6 which, according to fig. 3, includes two main joint sections 6a and 6b along the main axis. An elastic connecting piece 8 in the form of an angled bending spring is, as shown in fig. 3, arranged between the two main joint sections 6a and 6b. Through side joints 10 and 12, the connecting piece is connected to the lower part-2 and respectively
lokket 4.lid 4.
Fig. 4 viser en omvendt anordning. Innretningen omfatterFig. 4 shows an inverted device. The facility includes
i dette tilfelle bare et enkelt hovedledd 6, mens det på begge sider av dette er anordnet to bueformede, fjærende forbindelses-stykker 8a og 8b. Disse er forbundet med underdelen og lokket gjennom sideledd 10 og 12. in this case only a single main link 6, while two arc-shaped, springy connecting pieces 8a and 8b are arranged on both sides of this. These are connected to the lower part and the lid through side joints 10 and 12.
Ved dreiing av lokket fra den viste åpen-stilling mot underdelen, vil det fjærende forbindelsesstykke deformeres elastisk. Det virker derved som en strekkfjær. Omtrent midt i sin svinge-bane inntar snepperthengslet en labil likevektsstilling hvori hovedleddaksen og sideleddaksene forløper i samme plan. Fra denne stilling vil lokket innsmekke enten i lukke-stilling eller tilbake i åpen-stilling. When turning the lid from the shown open position towards the lower part, the springy connecting piece will deform elastically. It thereby acts as a tension spring. Approximately in the middle of its swing path, the snap hinge assumes a labile equilibrium position in which the main joint axis and the side joint axes run in the same plane. From this position, the lid will snap either into the closed position or back into the open position.
Som det fremgår av fig. 2, er hovedleddet 6 og sideleddene 10 og 12 utformet som snepperthengsler av kjent type, hvor lengden på tvers av leddaksen er meget liten. Ifølge fig. 1 er derimot hovedleddet 6' utformet som et bånd hvis lengde er As can be seen from fig. 2, the main link 6 and the side links 10 and 12 are designed as snap hinges of a known type, where the length across the joint axis is very small. According to fig. 1, on the other hand, the main link 6' is designed as a band whose length is
3-8 ganger båndtykkelsen. Tykkelsen kan derved utgjøre eksempelvis 0,3 mm og lengden 1 - 2 mm. Hvis også sideleddene 10' og 12' utformes som bånd, vil forholdene mellom båndlengde og bånd-tykkelse fremdeles være de samme. 3-8 times the tape thickness. The thickness can therefore amount to, for example, 0.3 mm and the length 1 - 2 mm. If the side members 10' and 12' are also designed as bands, the ratios between band length and band thickness will still be the same.
