Description
Denne oppfinnelse angår et lokk for beholdere som skal anvendes til løse produkter, særlig sådanne som er nedlagt i en væske, hvilket lokk har minst ett i området for beholderens munning forløpende, omkringgående tetningsområde for tettende inngrep med beholderveggen, beholdertoppen og/eller med deler som er utformet i ett med beholderveggen, og en lokkflate, med hvilken det i ett er formet et antall nedad forløpende nedholdere som i det vesentlige står loddrett på lokkflaten. This invention relates to a lid for containers to be used for loose products, in particular those that are immersed in a liquid, which lid has at least one continuous, circumferential sealing area in the area of the mouth of the container for sealing engagement with the container wall, the container top and/or with parts that is designed in one with the container wall, and a lid surface, with which a number of downwardly extending retainers are formed in one, which essentially stand vertically on the lid surface.
For i en beholder for f.eks. sildestykker i For in a container for e.g. herring pieces in
lake å holde stykkene nede i laken, benyttes i dag i alminne-lighet en sirkelformet rist med en rundtgående flens som for-løper mot beholderens lokk og med en sentralt anbrakt gripe-tapp. En sådan nedholderrist er ønskelig for å sikre at sildene trykkes ned i laken og derved holdes friske inntil sildestykkene tas ut. En sådan uttagbar silderist må nød-vendigvis fremstilles i en særskilt form, således at en normalt markedsført sildebeholder vil bestå av tre plast-deler, nemlig lokk, beholder og rist. Når brukeren skal ta ut en sild, må han altså først fjerne lokket og deretter fjerne risten som er våt av lake, ubehagelig å håndtere og vanskelig å legge fra seg uten at noe av laken spilles. sheet to keep the pieces down in the sheet, a circular grate is generally used today with a circumferential flange that extends towards the lid of the container and with a centrally placed gripping pin. Such a holding grate is desirable to ensure that the herring are pressed down into the sheet and thereby kept fresh until the herring pieces are taken out. Such a removable herring grate must necessarily be produced in a special form, so that a normally marketed herring container will consist of three plastic parts, namely lid, container and grate. When the user wants to take out a herring, he must first remove the lid and then remove the grate, which is wet with brine, uncomfortable to handle and difficult to put down without spilling some of the brine.

og FR-bruksmønster 7304686 er forskjellige nedholderorganer kjent som iform av særskilt del settes inn i lokk hhv. beholderen. and FR usage pattern 7304686 are different retaining means known as in the form of a separate part inserted into the lid or the container.
Fra NO-B- 126 674 er kjent et plastlokk for tønner, hvor en indre flens ligger an mot tønnens innervegg. Ut for og over inngrepsområder er det i lokket formet i det vesentlige diagonalt gjennomgående ribber, hvis formål bare er å forsterke lokkflaten og eventuelt lokkets indre flens mot inntrykking. Disse ribber forløper prinsipielt ikke ned under den omløpende indre henholdsvis ytre tetningskant og er således uegnet til å holde et produkt nede i en lake. From NO-B-126 674, a plastic lid for barrels is known, where an inner flange rests against the inner wall of the barrel. Beyond and above the areas of engagement, there are essentially diagonally continuous ribs formed in the lid, the purpose of which is only to reinforce the lid surface and possibly the lid's inner flange against indentation. In principle, these ribs do not extend below the circumferential inner or outer sealing edge and are thus unsuitable for holding a product down in a sheet.
Ut over dette er ribbene anbrakt med for store vinkelmellom-rom til effektivt å hindre produkter i å trenge opp i disse. In addition to this, the ribs are placed with excessively large angular spaces to effectively prevent products from penetrating into them.
Formålet med oppfinnelsen er å skaffe et lokk, hvor det i ett med lokket er formet nedholdere som holder produktet effektivt nede i en lake, inntil produktet i beholderen skal tas ut, hvilket lokk er materialbesparende, enkelt og billig å fremstille. The purpose of the invention is to provide a lid, where retainers are formed together with the lid to effectively hold the product down in a sheet, until the product in the container is to be taken out, which lid is material-saving, simple and cheap to manufacture.
Dette formål oppnås ved at det innledningsvis omtalte lokk utmerker seg ved at nedholderene er utformet som aksialt nedadrettede plater fra lokkf latens underside. Derved oppnås at man ikke behøver å fremstille en ekstra nedholder, hvilket medfører besparelser både med hensyn til materiale, produksjonsforløp, transport og ileggingsarbeide. Dessuten er et sådant formet lokk mer brukervennlig enn de løse rister som hittil har vært benyttet spesielt i forbindelse med i lake lagte sild. This purpose is achieved by the fact that the lid mentioned at the outset is distinguished by the fact that the retainers are designed as axially downward-directed plates from the underside of the lid surface. Thereby, it is achieved that there is no need to manufacture an additional retainer, which results in savings both in terms of material, production process, transport and installation work. What's more, such a shaped lid is more user-friendly than the loose grates that have so far been used, especially in connection with brined herring.
Spesielle utførelser av lokket ifølge oppfinnelsen fremgår av de uselvstendige krav. Special designs of the lid according to the invention appear from the independent claims.
Lokket ifølge oppfinnelsen skal beskrives nærmere nedenfor under henvisning til de på tegningen viste utførel-seseksempler. På tegningene viser fig. 1 et lokk med nedholdere ifølge oppfinnelsen, sett nedenfra, delvis skjematisk, fig. 2 viser lokket ifølge fig. 1 delvis i snitt, sett fra siden, og fig. 3 to på hinannen stablet lokk med nedholdere ifølge oppfinnelsen ved en annen henholdsvis tredje utførelse. The lid according to the invention will be described in more detail below with reference to the design examples shown in the drawing. In the drawings, fig. 1 a lid with retainers according to the invention, seen from below, partly schematically, fig. 2 shows the lid according to fig. 1 partially in section, seen from the side, and fig. 3 two lids stacked on top of each other with retainers according to the invention in another or third embodiment.
Den for øyeblikket foretrukne utførelse av lokket The currently preferred design of the lid
ifølge oppfinnelsen er vist på fig. 1 og 2. according to the invention is shown in fig. 1 and 2.
De på tegningen viste lokk la, lb og lc har som vist på fig. 3 rundtgående periferiske flenser 2, 3 med indre og ytre rundtgående inngrepspartier 4 og 5 til tettende inngrep med tilsvarende rundtgående inngrepsdeler 6 og 7 (på fig. 3 delvis vist) beholders 8 kantområde. I stedet for eller for supplering av disse tetningspartier og -deler kan lokk og beholder også være utformet for tettende inngrep mellom beholderens oppadvendende kantflate og en tilsvarende The lids la, lb and lc shown in the drawing have, as shown in fig. 3 circumferential circumferential flanges 2, 3 with inner and outer circumferential engagement parts 4 and 5 for sealing engagement with corresponding circumferential engagement parts 6 and 7 (in Fig. 3 partially shown) container 8 edge area. Instead of or in addition to these sealing parts and parts, the lid and container can also be designed for sealing engagement between the container's upward-facing edge surface and a corresponding
plan lokkflate. flat lid surface.
Ifølge oppfinnelsen er det i ett med lokkflaten 9 formet et antall nedholdere i form av nedadrettede og radialt forløpende fliker 11, 12, 13 som ved påsatt lokk for-løper inn i beholderens 8 indre. Ved det viste eksempel er der tyve jevnt fordelte fliker, idet vinkelen mellom en flik og den neste er 18°. Flikene forløper ut fra hvert sitt punkt på en felles sirkel innenfor lokkflatens 9 periferiske begrensning, dvs. et stykke innenfor overgangen mellom skrå-flaten 10 og lokkflatens 9 vannrette del. Ved det på fig. 1 og 2 viste eksempel er hver femte flik 11 en lang flik som forløper til tett ved lokkflatens 9 sentrum, og den avsluttes av et dermed i ett formet avstivningsorgan i form av en rettlinjet eller, som vist, en sirkelbueformet flens 14a. På, det på fig. 3 nedentil viste lokk lb er den lange flik 11b ført gjennom en rettlinjet eller fortrinnsvis en sirkelbueformet flens 14b og nærmere mot sentrum. På det på fig. 3 oventil viste lokk lc er den lange flik lic ført gjennom en rettlinjet eller sirkelbueformet flens 14c og helt til sentrum, hvor den støter sammen med de øvrige lange fliker lic. Mellomrommene 17 mellom de rettlinjede eller sirkelbueformede fliker 14a, 14b, 14c sikrer at et ved lokkets påsetning på beholderen dannet overtrykk ved trykk på lokket også kan unnvike fra det midterste rom. According to the invention, a number of retainers in the form of downwardly directed and radially extending tabs 11, 12, 13 are formed together with the lid surface 9, which extend into the interior of the container 8 when the lid is attached. In the example shown, there are twenty evenly spaced tabs, the angle between one tab and the next being 18°. The flaps extend from each point on a common circle within the peripheral limitation of the lid surface 9, i.e. a distance within the transition between the inclined surface 10 and the horizontal part of the lid surface 9. By that in fig. 1 and 2 shown example, every fifth flap 11 is a long flap which extends close to the center of the lid surface 9, and it is terminated by a stiffening member thus formed in one in the form of a rectilinear or, as shown, a circular arc-shaped flange 14a. On, that in fig. 3 lid lb shown below, the long flap 11b is led through a rectilinear or preferably a circular arc-shaped flange 14b and closer to the center. On that in fig. 3 lid lc shown above, the long tab lic is led through a rectilinear or circular arc-shaped flange 14c and all the way to the center, where it collides with the other long tabs lic. The spaces 17 between the rectilinear or arc-shaped flaps 14a, 14b, 14c ensure that an overpressure created when the lid is placed on the container by pressure on the lid can also escape from the middle space.
De mellom de lange fliker 11 formede fliker 12, Those between the long tabs 11 shaped tabs 12,
13 er dels radialt halvlange fliker 12 og mellom disse beliggende radialt korte fliker 13. Alle fliker 11, 12 og 13 har nær ved sin radialt ytre ende et avstivningsorgan i form av i flikenes fulle høyde h på begge sider forløpende søyledannende vulster 15. Tilsvarende vulster 16 er formet på de halvlange fliker 12 nær deres radialt indre ende. 13 are partly radially half-long tabs 12 and radially short tabs 13 located between these. All tabs 11, 12 and 13 have, close to their radially outer end, a stiffening member in the form of column-forming beads 15 extending over the full height h of the tabs on both sides. Corresponding beads 16 is formed on the semi-long tabs 12 near their radially inner end.
Disse avstivede vulster 15, 16 letter lokkenes utforming. These stiffened beads 15, 16 facilitate the design of the lids.
Som vist på fig. 3 er flikenes 11, 12, 13 høyde h noe mindre enn avstanden A mellom under- og oversiden av på hverandre stablede lokks lokkflater. Dette medfører at flikene ikke hindrer lokkenes stabling, men at de allikevel har en tilstrekkelig høyde til å holde i en væske nedlagte produkter med i det vesentlige samme spesifikke vekt som væsken, f.eks. sild, agurker, m.m., nede i laken, inntil emballasjen åpnes av brukeren. Høyden h er ca. 85-98 %, fortrinnsvis 90-95 % og særlig ca. 93 % av avstanden A. As shown in fig. 3, the height h of the tabs 11, 12, 13 is slightly less than the distance A between the underside and the top of the lid surfaces of the lids stacked on top of each other. This means that the tabs do not prevent the lids from being stacked, but that they still have a sufficient height to hold products placed in a liquid with essentially the same specific weight as the liquid, e.g. herring, cucumbers, etc., down in the sheet, until the packaging is opened by the user. The height h is approx. 85-98%, preferably 90-95% and especially approx. 93% of distance A.
Det viste lokk har en diameter på f.eks. 10-15 The lid shown has a diameter of e.g. 10-15
cm, og der er ved hjelp av de ovenfor nevnte fliker i ett med lokkflaten formet et antall nedad forløpende nedholdere som er anbrakt med små innbyrdes mellomrom, står i det vesentlige vinkelrett på lokkflaten og har en høyde h på mellom 1/5 cm, and with the help of the above-mentioned tabs in one with the lid surface, a number of downwardly extending retainers are formed which are placed with small spaces between them, stand essentially perpendicular to the lid surface and have a height h of between 1/5
og tre ganger høyden R av lokket målt fra lokkflatens hhv. lokkflensens nedre til lokktoppkatens øvre begrensning. I and three times the height R of the lid measured from the lid surface or the lid flange's lower to the lid top's upper limit. IN
det konkret viste tilfelle er høyden h ca. 1/3 av høyden H. the specifically shown case is the height h approx. 1/3 of the height H.
Av hensyn til utformingen foretrekkes det at flikene 11, 12 og 13 er konisk tilspissede i retning bort fra lokkflaten 9 og at de har fra lokkflaten skrått nedad forløpende endekanter 17. For reasons of design, it is preferred that the tabs 11, 12 and 13 are conically pointed in the direction away from the lid surface 9 and that they have end edges 17 extending obliquely downwards from the lid surface.
De på fig. 1-3 viste lokk er forøvrig utformet således at de er stabelbare, og som vist på fig. 3 er flikenes høyde således valgt at de ikke hindrer lokkenes stabling. Those in fig. 1-3 lids are otherwise designed so that they are stackable, and as shown in fig. 3, the height of the tabs is chosen in such a way that they do not prevent the stacking of the lids.
Lokket er fortrinnsvis fremstilt av polypropylen eller av polyetylen som består av en blanding av polyetylen med stor spesifikk vekt (HD) og en polyetylen med lav spesifikk vekt (LD), hvor forholdet HD/LD ligger mellom 75/25 og 50/50. The lid is preferably made of polypropylene or of polyethylene consisting of a mixture of polyethylene with a high specific weight (HD) and a polyethylene with a low specific weight (LD), where the HD/LD ratio is between 75/25 and 50/50.
Ut over de viste utførelser kan oppfinnelsens gjenstand varieres på forskjellig måte. Det er således inn-lysende at flikenes 11, 12, 13 antall og vinkelen a mellom disse kan endres med lokkenes størrelse, således at vinkelen a ved større lokk blir mindre og større for mindre lokk. Det viste eksempel er beregnet for et lokk med en ytre diameter på ca. 15 cm. Ved mindre lokk kan enten de korte 13 eller de halvlange 12 fliker sløyfes, og ved større lokk kan man benytte flere fliker med andre relative lengder enn de viste. In addition to the embodiments shown, the object of the invention can be varied in different ways. It is thus obvious that the number of tabs 11, 12, 13 and the angle a between them can be changed with the size of the lids, so that the angle a for larger lids becomes smaller and larger for smaller lids. The example shown is intended for a lid with an outer diameter of approx. 15 cm. For smaller lids, either the short 13 or the half-length 12 tabs can be looped, and for larger lids, you can use more tabs with different relative lengths than those shown.
I stedet for radialt forløpende fliker kan der benyttes i omkretsretningen forløpende konsentriske fliker, i det vesentlige av samme form som fliken 14a, dvs. at flikene er sirkelbueformede avsnitt eller er rette og anbrakt i et mønster av innenfor hverandre beliggende, i det vesentlige konsentriske polygoner, sirkler eller ovaler. Flikene kan dog også være tenkt anbrakt i et mer vilkårlig mønster. De kan ha avstivningsorganer ved en eller begge ender eller eventuelt midt på flikene. Det er også klart at flikene ifølge oppfinnelsen kan formes i ett med lokket som ikke har en forsenket, eller som har en bare noe forsenket lokkflate, idet flikenes høyde h i så fall fortrinnsvis skal være lik eller ca. to til tre ganger lokkets høyde H. Ennvidere kan flikene utelates og helt erstattes av et antall loddrett nedad forløpende søyler eller tettsittende tapper av i det vesentlige samme form som vulstene 15, 16. Instead of radially extending flaps, circumferentially extending concentric flaps can be used, substantially of the same shape as flap 14a, i.e. that the flaps are circular arc-shaped sections or are straight and placed in a pattern of substantially concentric polygons situated within each other , circles or ovals. However, the tabs can also be arranged in a more arbitrary pattern. They can have stiffening means at one or both ends or possibly in the middle of the tabs. It is also clear that the tabs according to the invention can be formed in one with the lid which does not have a recessed, or which has only a slightly recessed lid surface, the height of the tabs in that case should preferably be equal to or approx. two to three times the lid's height H. Furthermore, the tabs can be omitted and completely replaced by a number of vertically downward running columns or close-fitting studs of essentially the same shape as the beads 15, 16.
