Abstract
Beholderemne med i ett stykke fremstilt sidevegg, lokk og avrivningsanordning.Container blank with one-piece side wall, lid and tear-off device.
Description
Oppfinnelsen angår et beholderemne med i ett stykke fremstilt sidevegg, lokk og avrivningsanordning for lokket, hvilket emne er beregnet til etter fylling å lukkes med en separat fremstilt bunn. The invention relates to a container blank with side wall, lid and tear-off device for the lid produced in one piece, which blank is intended to be closed after filling with a separately produced bottom.
Fra beskrivelsen til dansk patent nr. 127.376 erFrom the description of Danish patent no. 127,376 is
det kjent en sprøytestøpt plastbeholder sammensatt av dels en beholderdel som omfatter et beholderlegeme, en tømmeåpning og et oppbrytbart lukke, og dels en bunndel. Beholderens tverrsnitt avtar fra bunnen mot lukket og dette lukke'/, kan rives opp uten anvendelse av verktøy. Beholderemnene er utformet an injection-molded plastic container composed of partly a container part comprising a container body, an emptying opening and a breakable closure, and partly a bottom part is known. The cross-section of the container decreases from the bottom towards the closed and this closure can be torn open without the use of tools. The container blanks are designed
slik at de kan stables.so that they can be stacked.
Avrivningsanordningen på det kjente beholderemne er en sirkulær rivestrimmel beliggende i beholderens øverste toppflate. Rivestrimmelen er avgrenset med svekningslinjer i materialet og har en trekkring ved hjelp av hvilken den ring-formede strimmelen og den innenfor i denne beliggende del av lukket kan rives løs fra beholderen. Etter åpningen av beholderen kan det påsettes et lokk på den øverste oppstående kraven omkring åpningen. The tear-off device on the known container blank is a circular tear-off strip located in the upper top surface of the container. The tearing strip is delimited by lines of weakness in the material and has a pulling ring by means of which the ring-shaped strip and the part of the closure located within this can be torn loose from the container. After opening the container, a lid can be placed on the uppermost upright collar around the opening.
Den kjente beholder byr på betydelige fordeler, idet den bare består av to hver for seg sammenhengende deler, nem-lig beholderemne og bunn, som etter fylling av beholderen fra bunnen settes sammen hensiktsmessig ved friksjonssveising. Åpningen av beholderen foregår ved trekk i ringen i aksiell retning, og etter at lukket er brutt, kan det separate lokket påsettes. The known container offers significant advantages, as it only consists of two separately connected parts, namely the container blank and the bottom, which, after filling the container from the bottom, are suitably assembled by friction welding. The container is opened by pulling the ring in an axial direction, and after the closure has been broken, the separate lid can be attached.
Foreliggende oppfinnelse går ut på den erkjennelseThe present invention is based on that realization
at uansett den kjente beholders fortrinn i forhold til tid-ligere kjente emballasjer lider den av en rekke ulemper både that regardless of the known container's advantages in relation to previously known packaging, it suffers from a number of disadvantages both
i produksjonsteknisk og i bruksmessig henseende.in terms of production technology and usage.
Med oppfinnelsen tilsikter man å løse den oppgaveThe invention aims to solve that task
å tilveiebringe en beholderkonstruksjon som er mindre ressurs-krevende, enklere å. :freinstille og mere f orbrukervennlig. to provide a container construction that is less resource-demanding, easier to dispose of and more user-friendly.
Ifølge oppfinnelsen løses denne oppgave ved at avrivningsanordningen er en i beholderveggen rundtgående rivestrimmel mellom beholderveggens Øverste kant og den nederste kant av en på lokket rundtgående sarg, som er innrettet til etter fjerningen av rivestrimmelen, som et lokk å kunne gripe inn med beholderveggens øverste kantsone. According to the invention, this task is solved by the tear-off device being a tear strip running around the container wall between the top edge of the container wall and the bottom edge of a rim running around the lid, which is arranged so that after the removal of the tear strip, like a lid, it can engage with the top edge zone of the container wall.
Ved konstruksjonen ifølge foreliggende oppfinnelseIn the construction according to the present invention
er lukket og lokket forenklet til en enkelt del, hvorved ressursforbruket blir mindre. Man unngår videre den rundtgående, oppstående kanten omkring beholderåpningen som i den kjente konstruksjonen er nødvendig av flere årsaker. Også der-ved reduseres materialforbruket, særlig når det er tale om beholdere med store åpninger, f.eks. spann eller bokser til maling. is closed and the lid simplified to a single part, whereby resource consumption is reduced. The circumferential, raised edge around the container opening, which in the known construction is necessary for several reasons, is also avoided. This also reduces material consumption, especially when it comes to containers with large openings, e.g. buckets or cans for paint.
Videre unngår man det rundtgående,uregelmessige fremspring som oppstår når lukket brytes ved riving, og som kan være sjenerende særlig véd uthelling av tyktflytende væsker. I. sprøyteteknisk henseende frembyr beholderemnet ifølge oppfinnelsen den fordel at materialet, som normalt inn-føres i støpeformen på et sted som ligger sentralt i lokkets toppflate, ikke skal bevege seg i opp- eller nedadgående retning når det forlater lokkflaten. Furthermore, you avoid the circular, irregular projection that occurs when the closure is broken during tearing, and which can be embarrassing, especially when viscous liquids are poured. I. In terms of injection technology, the container blank according to the invention offers the advantage that the material, which is normally introduced into the mold at a place centrally located in the lid's top surface, should not move in an upward or downward direction when it leaves the lid surface.
Ved konstruksjonen ifølge oppfinnelsen løses sam-tidig et annet problem ved beholdere som etter åpning skal kunne lukkes med et lokk. Når beholder og lokk fremstilles fullstendig separat eller bare sammenhengende med en enkelt streng av materiale, skjer det ofte at lokk;og beholder ikke passer sammen, selv om man har vært meget påpasselig ved frem-stilling av formene. Dette skyldes små variasjoner i materiale og i fremstillingsprosessen. Når lokket og den del av beholderen hvorpå lokket skal anbringes imidlertid fremstilles i ett stykke, vil disse uregelmessigheter ikke gjøre seg bemerket, The construction according to the invention simultaneously solves another problem with containers which, after opening, must be able to be closed with a lid. When the container and lid are produced completely separately or only connected with a single strand of material, it often happens that the lid and container do not fit together, even if great care has been taken when making the molds. This is due to small variations in material and in the manufacturing process. However, when the lid and the part of the container on which the lid is to be placed are produced in one piece, these irregularities will not be noticeable,
og lokket vil i alle tilfelle passe til beholderen.and the lid will in any case fit the container.
I en hensiktsmessig utførelsesform for beholderemnet ifølge oppfinnelsen har lokkets sarg og beholderveggens øverste kantsone innbyrdes komplementære fastholdelsesorganer, hvilket medfører at det kreves overvinnelse av en større kraft ved fjerning av lokket, slik at risikoen for at lokket faller av hvis beholderen velter er mindre. Fastholdelsesorganene kan være motsvarende, rundtgående fremspring som griper inn i hverandre ved snepplåsvirkning. In an appropriate embodiment of the container blank according to the invention, the rim of the lid and the top edge zone of the container wall have mutually complementary retaining means, which means that a greater force must be overcome when removing the lid, so that the risk of the lid falling off if the container overturns is smaller. The retaining means can be corresponding, circular protrusions that engage each other by a snap-lock effect.
Det er en fordel at rivestrimmelen har en med rivestrimmelen sammenhengeride trekkflik som utgjør et sikkert grep for utøvelse av et radielt strekk i rivestrimmelen. Et radielt strekk vil i alminnelighet gi bedre kraft over åpnings-prosessen enn det aksielle trekk som må utøves ved den kjente beholder. It is an advantage that the tear strip has a pull tab connected to the tear strip which forms a secure grip for exerting a radial stretch in the tear strip. A radial pull will generally give better force over the opening process than the axial pull that must be exerted with the known container.
Med henblikk på å lette avløftingen av gjenbruks-lokket, utformes beholderemnet hensiktsmessig slik at lokkets øverste flate i det minste stedvis rager ut over sargen til dannelse av et grep for fingrene.'In order to facilitate the lifting of the reusable lid, the container blank is appropriately designed so that the top surface of the lid at least in some places protrudes above the rim to form a grip for the fingers.
Konstruksjonen ifølge oppfinnelser åpner mulighetThe construction according to inventions opens up possibilities
for på en enkel måte å tilveiebringe en plombering, slik at kunden selv kan kontrollere om beholder har vært åpnet. Dette oppnås hensiktsmessig ved hjelp av en i ett med lokket og trekkfliken fremstilt forseglingsstreng som automatisk brytes når trekkfliken påvirkes til åpningen av beholderen. in order to provide a seal in a simple way, so that the customer can check for himself whether the container has been opened. This is suitably achieved by means of a sealing string produced in one piece with the lid and the pull tab, which automatically breaks when the pull tab is influenced to open the container.
Ved beholderemner fremstilt i plast med avtagende tverrsnitt fra bunnen mot lokket, slik at flere slike beholderemner kan stables, er det alminnelig å forsyne beholderveggen med stableknaster på innsiden, slik at man unngår at de sammen-stablede beholderemnene når de enkeltvis skal innføres i en fyllemaskin, henger sammen på grunn av den nære kontakt. Slike stableknaster som opptrer som lokale fortykkelser av beholderveggen, medfører imidlertid ofte såkalt siging som viser seg som fordypninger i beholderveggens ytre side. Slike fordypninger ødelegger beholderens utseende og vanskeliggjør påføring av trykt tekst eller annen utsmykning. Denne ulempe kan unngås ved beholderemnet ifølge oppfinnelsen ved at lokkets øverste, ut-^over sargen ragende flate, fortrinnsvis en radiell flens, er utformet slik at den ved stabling kommer til å ligge an mot et med henblikk på dette rundtgående anslag innvendig i den sam virkende beholderen, hvilket anslag er slik at to nabobeholder-emner ikke kan skyves så tett sammen at det oppstår klemming eller suging ved atskillelsen. Da anslaget alene tilveie-bringes ved en innsnevring av materiale i veggen uten endring av veggtykkelsen, oppstår det ingen sigingsproblemer. Flensen på den øverste flaten av lokket beskytter forøvrig trekkfliken, og hindrer at den kommer i veien ved stablingen. For container blanks made of plastic with a decreasing cross-section from the bottom towards the lid, so that several such container blanks can be stacked, it is common to provide the container wall with stacking lugs on the inside, so that the stacked container blanks are avoided when they are to be introduced individually into a filling machine , are connected due to the close contact. However, such stacking knobs which act as local thickenings of the container wall often result in so-called seepage which manifests itself as indentations in the outer side of the container wall. Such recesses spoil the appearance of the container and make it difficult to apply printed text or other decoration. This disadvantage can be avoided with the container blank according to the invention by the fact that the top surface of the lid, protruding beyond the rim, preferably a radial flange, is designed so that, when stacked, it comes to rest against a circumferential abutment inside the same acting container, which estimate is such that two neighboring container blanks cannot be pushed so close together that pinching or suction occurs during separation. As the impact alone is provided by a narrowing of material in the wall without changing the wall thickness, no seepage problems arise. The flange on the top surface of the lid also protects the pull tab, and prevents it from getting in the way when stacking.
Oppfinnelsen skal i det følgende forklares nærmere ved hjelp av et utførelseseksempel på et beholderemne ifølge oppfinnelsen og under henvisning til tegningen, der In the following, the invention will be explained in more detail by means of an embodiment of a container blank according to the invention and with reference to the drawing, where

fig. 6 viser to med bunn sammensatte beholdere stablet på hverandre. fig. 6 shows two bottom-assembled containers stacked on top of each other.
Tegningen viser en beholder med et lokk og enThe drawing shows a container with a lid and a
konisk sidevegg 2 og en bunn 3-Beholderen er fremstilt ved sprøytestøping av plast i to deler, av hvilke den ene er vist i fig. 1 og 2,og omfatter lokket 1, veggen 2 og en mellom-liggende rivestrimmel 4 med trekkflik 5, ved hjelp av hvilken lokket 1 kan fjernes fra beholderveggen 2. conical side wall 2 and a bottom 3-The container is produced by injection molding of plastic in two parts, one of which is shown in fig. 1 and 2, and comprises the lid 1, the wall 2 and an intermediate tearing strip 4 with pull tab 5, by means of which the lid 1 can be removed from the container wall 2.
Rivestrimmelen 4 er-fremstilg med svekningslinjer 6, som kan være mer eller mindre diskontinuerlige for ved støpingen å skape en hensiktsmessig flytevei for plastmaterialet mellom lokk og vegg. The tear strip 4 is manufactured with weakening lines 6, which can be more or less discontinuous in order to create an appropriate flow path for the plastic material between the lid and the wall during molding.
På undersiden av lokket 1 er det en rundtgåendeOn the underside of the lid 1 there is a circular
sarg 7 med en utoverrettet kileformet ribbe eller vulst 8rim 7 with an outwardly directed wedge-shaped rib or bead 8
hele veien rundt, som er beregnet til inngrep med underkanten 9 av en innsnevret kantsone 10 øverst på beholderveggen 2, når lokket etter fjerningen av rivestrimmelen 4 settes på beholderen. all the way around, which is intended for engagement with the lower edge 9 of a narrowed edge zone 10 at the top of the container wall 2, when the lid is placed on the container after the tear strip 4 has been removed.
I plan med lokkets overside har dette en utoverrettet flens 11, og beholderveggen 2 er utformet med en inn-overrettet del 12, som danner en brysting 13 mot hvilken lokk-flensen 11 kan hvile når flere beholderemner stables i hverandre som vist i fig. 4, slik som det er vanlig for å spare plass ved oppbevaring av transport av denne type beholderemner. In plane with the upper side of the lid, this has an outwardly directed flange 11, and the container wall 2 is designed with an inwardly directed part 12, which forms a breastplate 13 against which the lid flange 11 can rest when several container blanks are stacked together as shown in fig. 4, as is usual to save space when storing and transporting this type of container blanks.
Mellom trekkfliken 5 og flensen 7 er det støpt en forseglingsflik 14 som brytes når man trekker i trekkfliken for å fjerne rivestrimmelen 4. Forseglingsfliken 14 er svekket ved trekkfliken slik at den etter å være brutt blir sittende på flensen 7j som- det vil fremgå av fig. 53og viser at beholderen har vært åpnet, selv om lokket 1 sitter på beholderen og lukker denne. Between the pull tab 5 and the flange 7, a sealing tab 14 is molded which breaks when you pull the pull tab to remove the tear strip 4. The sealing tab 14 is weakened by the pull tab so that after being broken it remains on the flange 7j as will be seen from fig . 53 and shows that the container has been opened, even if the lid 1 is on the container and closes it.
Som det fremgår av fig. 4 danner flensen 7 og den innsnevrede, øverste del av beholderen et hulrom for trekkfliken 5>slik at denne ikke sjenerer stablingen av beholderen. As can be seen from fig. 4, the flange 7 and the narrowed upper part of the container form a cavity for the pull tab 5> so that this does not interfere with the stacking of the container.
Som det fremgår av fig. 2 har beholderveggen 2 nedentil et rundtgående spor 15 som svarer til en oppoverrettet ribbe 16 langs bunnens 3 omkrets, som vist i fig. 3. Når beholderen er fylt, hvilket er skjedd med lokket vendende ned-over, settes bunnen 3 på beholderemnet med ribben 16 i sporet 15, og disse organene sveises sammen fortrinnsvis ved friksjonssveising. As can be seen from fig. 2, the container wall 2 below has a circumferential groove 15 which corresponds to an upwardly directed rib 16 along the circumference of the base 3, as shown in fig. 3. When the container is filled, which has happened with the lid facing downwards, the bottom 3 is placed on the container blank with the rib 16 in the groove 15, and these bodies are welded together preferably by friction welding.
Bunnen 3 er utformet med en fordypning 17 (fig. 3) som svarer til lokkets toppflate inklusive flensen 7, slik at fylte beholdere kan settes på hverandre i en stabil stabel som vist i fig. 6. The bottom 3 is designed with a recess 17 (fig. 3) which corresponds to the lid's top surface including the flange 7, so that filled containers can be placed on top of each other in a stable stack as shown in fig. 6.
Beholderemnene kan fylles opp med et romfang svarende opp til underkanten av rivestrimmelen 4 for den ferdige beholderen selv med et skummende fluidum, på grunn av det ekstra beholderomfang som svarer til rivestrimmelens og sargens 7 høyde. The container blanks can be filled up with a volume corresponding up to the lower edge of the tear strip 4 for the finished container itself with a foaming fluid, due to the additional container volume corresponding to the height of the tear strip and the edge 7.
