Description
Låseanordning for lokk. Locking device for lid.
Den foreliggende oppfinnelse vedrorer en låseanordning for lokk for beholder med i det minste delvis rundt åpningen anordnet fals, hvilken låseanordning består av i lokkets kant anordnede fliker. The present invention relates to a locking device for a lid for a container with a fold arranged at least partially around the opening, which locking device consists of tabs arranged on the edge of the lid.
Det er fra for kjent låseanordninger med fliker som kan boyes om en fals. Flikmaterialets egenskaper er imidlertid ikke elastiske men gir efterhvert bruddanvisning. En flik av vanlig type er fremstilt av blikk. Låsing med en slik flik er således kun mulig et begrenset antall ganger for det oppstår brudd i denne. There are already known locking devices with tabs that can be bent around a seam. However, the tab material's properties are not elastic, but eventually give indications of breakage. A tab of the usual type is made of tin. Locking with such a tab is thus only possible a limited number of times before it breaks.
Ved plastbeholdere er det imidlertid meget uhensiktsmessig å anvende en plastisk deformerbar flik da plasten ikke har slike egenskaper, og man således måtte innstope et fremmedelement i lokket, hvilket imidlertid vil være kostbart og lite tilfreds-stillende. Således anvender man ved mindre piastbehoIdere lokk som låses med sneppertvirkning. En sikker låseanordning av denne type for store plastbeholdere, f.eks. for industrielt bruk, krever imidlertid store krefter for betjening. Det foreligger således et stort behov for en enkel og driftssikker låseanordning for plastbeholdere, hvilken låseanordning er lite tid- og energikrevende ved betjening. In the case of plastic containers, however, it is very inappropriate to use a plastically deformable flap as the plastic does not have such properties, and one would thus have to stuff a foreign element into the lid, which would however be expensive and not satisfactory. Thus, for smaller piast containers, lids are used that lock with a snap action. A secure locking device of this type for large plastic containers, e.g. for industrial use, however, requires great effort to operate. There is thus a great need for a simple and reliable locking device for plastic containers, which locking device requires little time and energy to operate.
Den foreliggende oppfinnelse har som formål å eliminere de ovenfor nevnte ulemper og å tilveiebringe en enkel og drift-sikker låseanordning for plastbeholdere med lokk, hvilken låseanordning kan betjenes nærmest et ubegrenset antall ganger. The purpose of the present invention is to eliminate the above-mentioned disadvantages and to provide a simple and reliable locking device for plastic containers with a lid, which locking device can be operated almost an unlimited number of times.
Dette oppnås ifolge den foreliggende oppfinnelse ved at beholderens fals og i det minst en del av hver av lokkets fliker er elastiske slik at flikens ytre ende kan boyes rundt kanten av falsen og presses inn i rommet mellom falsens innside og beholderveggen der den fastholdes i låsestiIling ved inngrep med nevnte vegg. According to the present invention, this is achieved by the container's seam and at least part of each of the lid's flaps being elastic so that the outer end of the flap can be bent around the edge of the seam and pressed into the space between the inside of the seam and the container wall where it is held in a locking position by intervention with said wall.
Andre formål og trekk ifolge den foreliggende oppfinnelse vil fremgå nærmere nedenfor. Other purposes and features according to the present invention will appear in more detail below.
Oppfinnelsen skal nå nærmere beskrives ved hjelp av utforel-seseksempler under henvisning til de vedlagte tegninger, hvorpå The invention will now be described in more detail by means of embodiment examples with reference to the attached drawings, after which
fig. la viser et utsnitt av en plastbeholder med lokk og låse-anordningen ifolge den foreliggende oppfinnelse, fig. 1a shows a section of a plastic container with a lid and the locking device according to the present invention,
fig. lb viser et snitt efter linjen A-A ifolge fig. la, fig. lb shows a section along the line A-A according to fig. let,
fig. 2a viser en modifikasjon av utforelsen ifolge fig. la og fig. 2b viser et snitt efter linjen B-B ifolge fig. 2a. fig. 2a shows a modification of the embodiment according to fig. 1a and fig. 2b shows a section along the line B-B according to fig. 2a.
En plastbeholder 1 er forsynt med en langs beholderens kant forlbpende fals 2. Beholderens plastlokk 3 er forsynt med en tilsvarende fals 4 med en flik 5 med et tynnere omboyningsparti 6 i overgangen mellom lokk og flik. Når lokket 3 påfores beholderen, har fliken 5 en stilling som er antydet med en stiplet linje. Efter anbringelse av lokket ligger omboynings-partiet 6 i underkant av falsens 2 nedre kant 7, og fliken presses opp i falsens kant samtidig som man eventuelt tvinger denne noe utover idet flikens lengde D er storre enn falsens bredde C. Fjerner man nå den ytre påvirkning av fals og flik, vil den likevektstilstand oppstå som er antydet med helt opp-trukne linjer i fig. lb. Lokket 3 holdes på plass selv ved påvirkning av sterke vertikale krefter da den relativt stive flik ikke vil ha en tendens til å gli om falsens nedre kant 7. Den eneste mulighet for å frigjore fliken 5 fra låsestillingen er å tvinge beholderen og lokkets fals, f.eks. ved å gripe fast under beholderens fals ved siden av fliken, utover slik at flikens ytre ende kan passere beholderens side. Det elastiske omboyningsparti vil da automatisk fore fliken tilbake til stillingen som er angitt med en stiplet linje. Den kraft som kreves for utboyning av beholderens fals og som er en indikasjon på låsens sikkerhet, kan selvfolgelig avpasses for de forskjellige funk-sjoner og anvendelsesområder, fra små oppbevaringskar for hus-holdning til store industri-containere. A plastic container 1 is provided with a fold 2 running along the edge of the container. The container's plastic lid 3 is provided with a corresponding fold 4 with a flap 5 with a thinner omboyningsportion 6 in the transition between lid and flap. When the lid 3 is applied to the container, the tab 5 has a position indicated by a dashed line. After fitting the lid, the fold-over part 6 lies below the lower edge 7 of the fold 2, and the tab is pressed up into the edge of the fold at the same time as possibly forcing it outwards somewhat, as the length D of the tab is greater than the width C of the fold. If the external influence is now removed of fold and flap, the state of equilibrium will occur which is indicated by solid lines in fig. lb. The lid 3 is held in place even under the influence of strong vertical forces as the relatively rigid flap will not tend to slide around the lower edge of the fold 7. The only possibility to release the flap 5 from the locking position is to force the container and the fold of the lid, f .ex. by grasping under the container's seam next to the tab, outward so that the outer end of the tab can pass the side of the container. The elastic bending part will then automatically guide the tab back to the position indicated by a dashed line. The force required to unbend the container's seam and which is an indication of the lock's safety, can of course be adjusted for the different functions and areas of application, from small storage containers for households to large industrial containers.
I fig. 2b er vist en modifikasjon av utforelsen ifolge fig. la og lb. Her gis fliken 8 en ekstra sikring i låsestilling av et på undersiden av falsen anbragt fremspring 9. Man kan imidlertid istedenfor fremspring også anordne en utsparing for den samme funksjon. Flikens omboyningsparti 10 ligger her noe under falsens nedre kant 12. Således kan fliken ved åpning av beholderen lett boyes utover og anvendes som håndtak for fjerning av lokket. For dette formål er fliken forsynt med en utsparing II hvori man med en eller flere fingre eller med evt. mekanisk anordning kan gripe inn for å få bedre tak i fliken. Mari kan imidlertid istedenfor en utsparing også tenke ség å anordne en vulst eller lignende i samme hensikt. I nederste kant av lokkets kant er anordnet en vulst 13 for. i tillegg til låsen å fastholde lokket med en viss sneppertviskning. In fig. 2b shows a modification of the embodiment according to fig. let and lb. Here, the tab 8 is provided with an additional safeguard in the locked position by a projection 9 placed on the underside of the fold. However, instead of a projection, a recess can also be arranged for the same function. The fold-over part 10 of the tab lies somewhat below the lower edge 12 of the fold. Thus, when opening the container, the tab can be easily bent outwards and used as a handle for removing the lid. For this purpose, the flap is provided with a recess II in which one or more fingers or with any mechanical device can intervene to get a better grip on the flap. However, instead of a recess, Mari can also consider arranging a bead or similar for the same purpose. A bead 13 is arranged at the bottom edge of the lid's edge. in addition to the lock to retain the lid with a certain snapper.
