Description

Oppfinnelsen angår en lukkeanordning for en kunst-stoff beholde r omfattende et lokk med en lukkedel som griper om beholderveggens øvre ende, og et rundtgående spor som slutter seg til lukkedelen, idet beholderens øvre kant på The invention relates to a closing device for a plastic container comprising a lid with a closing part that grips the upper end of the container wall, and a circumferential groove that joins the closing part, the container's upper edge on

sin ytterside oppviser holdeknaster, og den ytre, om beholderveggen gripende vegg av lukkedelen oppviser til holdeknastene tilordnede åpninger og lokket er lukket med et bånd. its outer side has retaining lugs, and the outer wall of the closing part, which grips the container wall, has openings assigned to the retaining lugs and the lid is closed with a band.

En sådan kunststoffbeholder, en tønne eller et Such a plastic container, a barrel or something

fat av kunststoffer kjent fra DE-A- 2 82 7 848 . I den kjente beholder er lokket i hovedsaken lukket ved hjelp av en spennring eller et spennbånd. Ved en gjentatt anvendelse er lokket dårlig lukkbart, og ved kunststoffbeholdere er det av avgjørende betydning at alle deler kan fremstilles på rasjonell måte. barrels of plastics known from DE-A-2 82 7 848. In the known container, the lid is mainly closed by means of a clamping ring or a clamping band. With repeated use, the lid is difficult to close, and in the case of plastic containers it is of crucial importance that all parts can be produced in a rational way.

Fra US-A-3 707 240 er det kjent en lukkeanordning for flasker med et i ett stykke med lokket utformet avrivningsbånd, hvorved tetningen etter avrivningen i det vesent-lige skjer ved hjelp av lukkeanordningens innerdel. En sådan lukkeanordning er ikke egnet ved en beholder med vid hals for transport av matvarer eller farge. From US-A-3 707 240 there is known a closing device for bottles with a tear-off strip formed in one piece with the lid, whereby the sealing after the tear-off essentially takes place with the help of the inner part of the closing device. Such a closing device is not suitable for a container with a wide neck for the transport of foodstuffs or colour.

Endelig er det fra DE-A- 2 549 400 kjent en kunststoffbeholder med en mangekantet flens, hvor beholde- Finally, a plastic container with a polygonal flange is known from DE-A-2 549 400, where

ren oppviser en i et spor inngripende lukkedel for gjen- ren exhibits a closing part engaging in a groove for re-

tatt lukning, og som er særlig egnet for transport ved hjelp av jernbane eller lastevogner. Lokket kan sikres ekstra ved hjelp av et avrivningsbånd, men dette bånd må imidlertid anbringes separat. closed, and which are particularly suitable for transport by rail or lorries. The lid can be additionally secured by means of a tear-off strip, but this strip must, however, be fitted separately.

På bakgrunn av ovenstående er formålet med oppfinnelsen å forbedre lukkeanordningen på en slik måte at både lukket og beholderen kan fremstilles rasjonelt av sprøytestøpegods, at lokket er godt sikret mot støt, og at både avrivningsbåndet og lokket, etter fjerning av avrivningsbåndet, lettvint kan fjernes. On the basis of the above, the purpose of the invention is to improve the closure device in such a way that both the closed and the container can be manufactured rationally from injection molding, that the lid is well secured against impact, and that both the tear-off strip and the lid, after removal of the tear-off strip, can be easily removed.

Ovennevnte formål oppnås med en lukkeanordning The above purpose is achieved with a closing device

som utmerker seg ved de i patentkravene angitte, karakteri-serende trekk. which is distinguished by the characterizing features specified in the patent claims.

Oppfinnelsen skal beskrives nærmere i det The invention shall be described in more detail therein

følgende i forbindelse med utførelseseksempler under the following in connection with the execution examples below

henvisning til tegningene, der fig. 1 viser et grunnriss av et lokk ifølge oppfinnelsen, fig. 2 viser et sideriss av lukkeanordningen ifølge oppfinnelsen, fig. 3 viser lukkeanordningen ifølge oppfinnelsen i snitt, og fig. 4 viser et annet snitt gjennom lukkeanordningen ifølge oppfinnelsen. reference to the drawings, where fig. 1 shows a plan view of a lid according to the invention, fig. 2 shows a side view of the closing device according to the invention, fig. 3 shows the closing device according to the invention in section, and fig. 4 shows another section through the closing device according to the invention.

På fig. 1 er vist et lokk 1 med en lukke- eller stengedel 21 som oppviser en ytre, om beholderveggen gripende vegg 3 samt to vegger 5 og 6 som slutter seg til den ytre vegg 3 og danner et rundtgående spor 4 (se også fig. 3). Med veggene 5 og 6 er det forbundet en innenforliggende In fig. 1 shows a lid 1 with a closing or closing part 21 which exhibits an outer wall 3 gripping the container wall as well as two walls 5 and 6 which join the outer wall 3 and form a circumferential groove 4 (see also Fig. 3) . An interior is connected to walls 5 and 6

vulst 7 som tjener til forsterkning. I det rundtgående spor 4 er det anordnet forsterkningsribber 8. Av grunnrisset på fig. 1 fremgår videre åpninger 9 som er beregnet å gripe om tilsvarende holdeknaster på beholderen, samt to holdeører 10a og et holdeøre 10b som er anordnet på begge sider av et første svekningssted 22 i et avrivningsbånd 11 (se også fig. 2). På den andre side av de to holdeører 10a, er det på avrivningsbåndet anbrakt et andre svekningssted 22a, for helt å kunne fjerne stykket med de to ører. På fig. 2 fremgår videre perforeringer 12 mellom lokket 1 og avrivningsbåndet 11. bead 7 which serves for reinforcement. Reinforcement ribs 8 are arranged in the circumferential groove 4. From the ground plan in fig. 1 also shows openings 9 which are intended to grip corresponding retaining lugs on the container, as well as two retaining lugs 10a and a retaining lug 10b which are arranged on both sides of a first weakening point 22 in a tear-off band 11 (see also fig. 2). On the other side of the two holding lugs 10a, a second weakening point 22a is placed on the tear-off band, in order to be able to completely remove the piece with the two lugs. In fig. 2 also shows perforations 12 between the lid 1 and the tear-off strip 11.

Ved sin øvre ende oppviser beholderen 2 en mangekantet flens 13 med grupper av ribber 14 som tjener som låsemidler eller sperreanordninger. Den øvre ende 15 av beholderveggen er beliggende over denne flens og oppviser en fortykning 24, rundtgående forsterkningsribber 16 og holdeknaster 17 som svarer til åpningene 9. Slik det fremgår av fig. 3, er holdeknastene og avrivningsbåndet utformet på en slik måte at holdeknastene i den lukkede tilstand trykker på avrivningsbåndet og presser mot lokket. Mellom beholderveggens fortykning 24 og den om beholderveggen gripende vegg 3 av lokket befinner det seg en tetning 18. Mellom ørene 10a og 10b på avrivningsbåndet befinner det At its upper end, the container 2 has a polygonal flange 13 with groups of ribs 14 which serve as locking means or locking devices. The upper end 15 of the container wall is located above this flange and exhibits a thickening 24, circumferential reinforcement ribs 16 and holding lugs 17 which correspond to the openings 9. As can be seen from fig. 3, the retaining lugs and tear-off band are designed in such a way that in the closed state the retaining lugs press on the tear-off band and press against the lid. Between the thickening 24 of the container wall and the wall 3 of the lid that grips the container wall, there is a seal 18. Between the ears 10a and 10b of the tear-off strip there is

seg som nevnt et svekningssted 22 for å gjøre det mulig å themselves, as mentioned, a point of weakness 22 to make it possible to

åpne og å fjerne avrivningsbåndet uten verktøy, hvoretter lokket kan tas av. Slik det videre fremgår av fig. 3, open and to remove the tear-off strip without tools, after which the lid can be removed. As further appears from fig. 3,

er det under hver åpning 9 anordnet et sentreringsspor 19, slik at disse spor ved lokkets påsetning ved hjelp av drei-ning innraster på holdeknastenene 17, hvoretter lokket kan trykkes ned. a centering groove 19 is arranged under each opening 9, so that when the lid is put on, these grooves lock onto the retaining lugs 17 by turning, after which the lid can be pressed down.

For å muliggjøre gjentatt lukning av lokket, To enable repeated closing of the lid,

er det i dettes yttervegg 3 anordnet en rundtgående ribbe 2 3 som griper bak beholderveggens fortykning 24. Da åpningene 9 etter fjerningen av avrivningsbåndet er nedad åpne, forårsaker de at lokkets yttervegg 3 blir elastisk. a circumferential rib 2 3 is arranged in its outer wall 3 which grips behind the thickening 24 of the container wall. Since the openings 9 are open downwards after the removal of the tear-off strip, they cause the lid's outer wall 3 to become elastic.

På lokket er det videre mulig å anordne en ut-løpstut som eksempelvis kan være utført av metall eller kan være utført av en mykplast og være uttrekkbar. Forsterk-ningsribbene 8 kan oppvise en avsats 20 i hvilken beholder-bunnene passer inn ved stabling av beholderne på hverandre for å oppnå en god stablbarhet. Av den foregående beskri-velse fremgår det videre at både lokket og beholderen kan fremstilles i ett stykke av sprøytestøpegods. On the lid, it is also possible to arrange an outlet spout which can, for example, be made of metal or can be made of a soft plastic and be retractable. The reinforcement ribs 8 can have a ledge 20 into which the container bottoms fit when stacking the containers on top of each other to achieve good stackability. From the previous description, it is also clear that both the lid and the container can be produced in one piece of injection moulding.
