Description
i DK 171723 B1in DK 171723 B1
Opfindelsen angår et plastlåg 1 til en beholder 2, der kan være en plastspand.The invention relates to a plastic lid 1 to a container 2 which may be a plastic bucket.
Låget er fortrinsvis et snaplåg.The lid is preferably a snap lid.
Det kan udformes til en rund, firkantet eller oval beholder 5 med en udvendig 3 eller indvendig 4 snapkant.It can be formed into a round, square or oval container 5 with an outer 3 or inner 4 snap edge.
Kendte konstruktioner af plastlåg har den ulempe, at de falder af beholderen, hvis denne tabes, eller også fremstilles de så kraftige, at de skal skæres af beholderen 10 for at man kan komme til indholdet.Known plastic lid designs have the disadvantage that they fall off the container if dropped, or they are made so strong that they need to be cut by the container 10 to access the contents.
Formålet med denne opfindelse er, at kunne fremstille et låg, der ikke falder af beholderen, hvis denne tabes, men som alligevel kan tages af beholderen forholdsvis let.The object of this invention is to be able to produce a lid which does not fall off the container if dropped, but which can still be taken off the container relatively easily.
1515
Ved en beholders fald vil indholdet, idet den rammer underlaget, slå mod indersiden af låget, og dette slag forårsager et vridningsmoment på lågets rand 5 på alle eksisterende lågkonstruktioner.Upon the fall of a container, the contents, as it strikes the substrate, strike against the inside of the lid, causing this to cause a torque on the rim 5 of the lid on all existing lid structures.
20 Dette vridningsmoment er den primære årsag til, at låget falder af, ved en beholders fald.20 This torque is the primary cause of the lid falling off by the fall of a container.
Derfor er randen 5 af låget ved denne opfindelse forbundet flexibelt med midten af låget 6 langs toppen 7 af randen.Therefore, the rim 5 of the lid of this invention is flexibly connected to the center of the lid 6 along the top 7 of the rim.
25 Desuden er partiet 8 af låget indenfor randen deformérbart, så det lader midten af låget 6 bule ud, hvis beholderen tabes. Når dette sker, kan der ikke overføres et moment til randen af låget, der vil vride dette af beholderen.In addition, the portion 8 of the lid within the rim is deformable so that the middle of the lid 6 bulges if the container is dropped. When this happens, no torque can be transferred to the rim of the lid which will twist this by the container.
30 Især når lågets rand bliver siddende på beholderen, er der en risiko for at låget ved fald revner på grund af slaget.30 Especially when the lid of the lid is seated on the container, there is a risk that the lid will crack due to the stroke.
For at mindske dette slag på indersiden af låget, er det omkringløbende deformerbare område 8 i låget mellem lågets centrale del 6, og lågets rand 5 udført, så det, idet det 35 buler ud, optager så stor en del af faldenergien som muligt. Dette områdes formgivning giver mulighed for, at faldenergien absorberes over en længere vej ved lågets deformation, og slaget på låget derved bliver formindsket.To reduce this impact on the inside of the lid, the circumferentially deformable area 8 of the lid between the central portion 6 of the lid and the rim 5 of the lid is made so that, with 35 dents out, it absorbs as much of the fall energy as possible. The design of this area allows the fall energy to be absorbed over a longer path during lid deformation, thereby reducing the impact of the lid.
Man kan opnå en tilsvarende effekt ved at udforme een eller 40 flere omkringløbende svækkelseslinier 9.A similar effect can be obtained by designing one or more or more multiple weakening lines 9.
Ved at se på fig. 4, er det let at forestille sig, at midten af låget vil bule ud som vist på fig.3 ved et stort indvendigt overtryk idet de to svækkelseslinier 9 vil virke som hængsler.By looking at FIG. 4, it is easy to imagine that the middle of the lid will bulge as shown in Fig. 3 by a large internal overpressure, as the two weakening lines 9 will act as hinges.
45 Når lågets centrale del befinder sig i sin maximalt udspilede position som vist på fig. 3, vil overtrykket i beholderen overføres til randen af låget og dermed til snappet mellem låg og beholder, som rene trækkræfter, og 50 snappet vil dermed langt lettere kunne holde låget på beholderen, og dermed give emballagen en langt større faidstyrke.45 When the central part of the lid is in its maximum played position as shown in FIG. 3, the overpressure in the container will be transferred to the rim of the lid and thus to the snapping between the lid and the container, as pure pulling forces, and thus the snapping will be much easier to hold the lid of the container, thus giving the packaging a much greater moisture strength.
Faldenergien skal absorberes så jævnt som muligt, for at DK 171723 B1 2 mindske det maximale overtryk i beholderen ved fald.The fall energy must be absorbed as evenly as possible in order to reduce the maximum overpressure in the container in the event of a fall.
Dette opnås ved at anvende svækkelseslinier 9 eller formindsket godstykkelse 8 og, hvis ønsket, deformerbare ribber 10 i den deformerbare zone.This is achieved by using weakening lines 9 or diminished thickness 8 and, if desired, deformable ribs 10 in the deformable zone.
5 De ganske tyndvæggede ribber 10 vil, hvis de anvendes, blive strukket, og derved bidrage til, at faldenergien optages jævnt.5 The very thin-walled ribs 10, if used, will be stretched, thereby contributing to the fall energy being absorbed evenly.
De kan placeres radiært eller på skrå, og de kan udføres plane eller kurvede.They can be placed radially or obliquely and can be made flat or curved.
10 Ribberne kan naturligvis også placeres på oversiden af låget, men dette vil i så fald være vanskeligere at gøre rent.Of course, the ribs can also be placed on the top of the lid, but this will be more difficult to clean.
Den deformerbare zone skal desuden udformes under 15 hensyntagen til, at koniske bøtter stables uden mellemlæg på lågene af de understående bøtter.In addition, the deformable zone must be designed taking into account that tapered buckets are stacked without shims on the lids of the buckets below.
Opstablingen skal ske så stabilt som muligt. Flexibiliteten af den deformerbare zone er derfor minimeret i den radiære retning, hvor de ovenstående bøtter vil skabe spændinger i 20 lågene.The stacking should be as stable as possible. The flexibility of the deformable zone is therefore minimized in the radial direction, where the above buckets will create tension in the 20 lids.
Ved stabling af cylindriske bøtter, hvor der stables direkte på randen af låget, er dette forhold uden betydning, og man kan udføre den flexible zone som en bælg med een, som vist i fig.6, eller flere bølger.In stacking cylindrical buckets where stacked directly on the rim of the lid, this ratio is of no importance and the flexible zone can be made as a bellows with one, as shown in Fig. 6, or more waves.
2525
Tanken om at udføre låget flexibelt er ikke ny, som det ses af EPO patent ansøgning nr. 92304118.0 der omhandler et metalpladelåg.The idea of making the cover flexible is not new, as seen by EPO patent application No. 92304118.0 which deals with a metal plate cover.
Men her har man anbragt den flexible zone indenfor det 30 område, der belastes af ovenstående spande, og lågets rand kan derfor ikke følge spandens deformationer ved fald, hvorved det lettere falder af.But here, the flexible zone has been placed within the area loaded by the above buckets, and therefore the rim of the lid cannot follow the deformations of the bucket in case of fall, which makes it easier to fall off.
Desuden overføres faldenergien som et moment på lågets rand, der derved vrides af spanden.In addition, the fall energy is transmitted as a torque on the lid edge, thereby twisting the bucket.
35 I den danske patentansøgning 4949/69 er der ligså vist en flexibel grube indenfor det område, der belastes af en spand stillet på låget. Her viste sig den samme ulempe som ovenfor nævnt, at deformation af låg og spand ved et fald ikke kunne 40 følges ad, og låget derfor blev vredet af spanden.35 Danish patent application 4949/69 also shows a flexible pit within the area that is loaded by a bucket placed on the lid. Here, the same disadvantage as mentioned above showed that the lid and bucket deformation could not be followed by a fall and therefore the lid was twisted by the bucket.
Også AU patent ansøgningen nr. 8138723 der omhandler et plastlåg, beskriver et flexibelt låg. Men her har man kun opnået flexibilitet overfor tryk fra siden på beholderen. Et 45 indvendigt overtryk vil stadig vride låget af bøtten.Also, the AU patent application No. 8138723 which discloses a plastic lid discloses a flexible lid. But here, flexibility has been achieved only from side pressure on the container. A 45 inside overpressure will still twist the lid of the bucket.
Desuden vil en spand, stablet på låget, stå og gynge under transport, og dermed være ustabil.In addition, a bucket, stacked on the lid, will swing during transport, thus being unstable.
I EPO patentansøgning nr. 92250348.7 er det centrale parti 50 af låget tilsluttet et stykke oppe på randpartiet, men formålet med ansøgningen har ikke været at fremstille et faldsikkert låg, og det er heller ikke opnået med den viste udformning af randen, idet låget nærmest vil rulle af spanden ved et indvendigt overtryk i denne.In EPO Patent Application No. 92250348.7, the central portion 50 of the lid is connected to a piece on the edge portion, but the purpose of the application has not been to produce a fall-proof lid, nor has it been achieved with the shown design of the rim, since the lid will almost roll off the bucket by an internal overpressure in it.
3 DK 171723 B1 I EP patentansøgningen nr. O 642 983 Al er anført to omkringløbende hængsellinier. Formålet med dem er, at den centrale del af låget kan ekspandere ved indvendigt 5 overtryk, og dermed skaber et højere tætningstryk mellem låget og indersiden af beholderen.3 DK 171723 B1 EP patent application No. 0 642 983 A1 lists two circular hinge lines. The purpose of them is that the central part of the lid can expand at internal pressure, thus creating a higher sealing pressure between the lid and the inside of the container.
I nærværende ansøgning er hængsellinierne nævnt som en option, men er uden afgørende betydning for funktionen, idet man kan opnå den samme fleksibilitet ved at formindske 10 godstykkelsen i et område som vist i fig.2 pkt.8.In the present application, the hinge lines are mentioned as an option, but are of no decisive importance to the function, since the same flexibility can be achieved by reducing the thickness of the goods in an area as shown in Figure 2, point 8.
Fig. 1 viser et lodret tværsnit af en beholder 2 med et plastlåg 1.FIG. 1 shows a vertical cross-section of a container 2 with a plastic lid 1.
15 Fig. 2 viser et lodret tværsnit af lukkeanordningen af et låg 1 der er påsat en beholder 2 med et udvendigt snap 3. En deformerbar zone 8 i låget er opnået ved at mindske godstykkelsen i den skrå flade 8, der omslutter den midterste del af låget 6.FIG. 2 shows a vertical cross section of the closure device of a lid 1 fitted to a container 2 with an external snap 3. A deformable zone 8 in the lid is obtained by reducing the thickness of the material in the inclined surface 8 enclosing the middle part of the lid 6.
20 Den deformerbare zone 8 er forbundet flexibelt med randen af låget 5 i en linie 7 langs toppen af randen.The deformable zone 8 is flexibly connected to the rim of the lid 5 in a line 7 along the top of the rim.
10 viser en strækbar ribbe.10 shows a stretchable rib.
Fig. 3 viser et lodret tværsnit af det samme låg maximalt 25 udspilet. Det ses, hvordan den skrå flade 8 er blevet deformeret, og hvordan ribben 10 er blevet strukket.FIG. 3 shows a vertical cross-section of the same lid a maximum of 25 played out. It is seen how the oblique surface 8 has been deformed and how the rib 10 has been stretched.
Fig. 4 viser et lodret snit af lukkeanordningen af et låg 1 der er påsat en. beholder 2 med et udvendigt snap 3. Her er 30 lågets deformationsmulighed opnået ved at mindske godstykkelsen i to helt eller delvist omkringløbende linier 9, der vil virke som hængsler og tillade midten 6 af låget at bule ud ved et indvendigt overtryk i beholderen. Dette kan således ske uden at overføre et vridningsmoment til 35 lågets rand 5.FIG. 4 shows a vertical section of the closure device of a lid 1 affixed to one. container 2 with an external snap 3. Here, the deformation cap of the lid is obtained by reducing the thickness of the fabric in two fully or partially circumferential lines 9, which will act as hinges and allow the middle 6 of the lid to bulge out by an internal overpressure in the container. This can be done without transferring a torque to the rim 5 of the lid.
Fig. 5 viser et lodret tværsnit af lukkeanordningen af et låg 1, der snapper indvendigt i en beholder 2 med en indvendig snapkant 4. Lågets flexible zone 8 er forbundet 40 langs en linie 7, der kan virke som hængsel, med lågets rand 5.FIG. 5 shows a vertical cross-section of the closure device of a lid 1 which snaps inside of a container 2 with an inner snap edge 4. The flexible zone 8 of the lid is connected 40 along a line 7 which can act as a hinge, with the rim 5 of the lid.
Fig. 6 viser et lodret tværsnit af lukkeanordningen af et låg 1, der snapper indvendigt i en beholder 2 med en 45 indvendig snapkant 4. Lågets flexible zone, der i dette tilfælde er udformet som en bælg med en formindsket godstykkelse, der derved tillader deformation, er forbundet langs en linie 7, der kan virke som hængsel, med lågets rand 5.FIG. 6 shows a vertical cross section of the closure device of a lid 1 which snaps inside of a container 2 with a 45 inner snap edge 4. The flexible zone of the lid, which in this case is formed as a bellows with a reduced thickness of thickness, thereby permitting deformation, is connected along a line 7 which may act as a hinge, with the edge 5 of the lid.
