DK 168279 B1 iDK 168279 B1 i
Opfindelsen angår et emballageemne af den art, der er angivet i krav l's indledning.The invention relates to a packaging item of the kind set forth in the preamble of claim 1.
Sådanne emballageemner kendes fra DK-patentansøgning nr.Such packaging items are known from DK patent application no.
5 998/89. I de således kendte emballageemner, der er bestemt til at anvendes som ægbakker, er vinklen mellem de mod hinanden vendende sider i hver forhøjnings svøb i hovedsagen 60°, idet denne vinkel er valgt for at opnå den bedst mulige støtte for de emballerede æg.5 998/89. In the packing articles thus known, which are intended to be used as egg trays, the angle between the opposite sides of the envelope of each elevation is generally 60 °, this angle being chosen to obtain the best possible support for the packaged eggs.
10 I de senere år har man opdaget, at emballageemner af i princippet samme art kan anvendes som mellemlæg ved emballering af apparatur, der skal beskyttes mod stød, i en ydre emballage. Som eksempel kan nævnes stødfølsomt mekanisk-elektro-15 nisk udstyr, såsom videobåndoptagere, der skal emballeres i en ydre papkasse med henblik på forsendelse.10 In recent years, it has been discovered that packaging items of the same kind can, in principle, be used as shims when packaging equipment to be protected from impact in an outer packaging. For example, shock-sensitive mechanical-electronic equipment, such as VCRs, to be packaged in an outer cardboard box for shipment.
Når en på denne måde emballeret genstand udsættes for hårdhændet behandling, f.eks. ved fald på et hårdt underlag, 20 skal forhøjningerne i emballageemnet kunne optage i det mindste en del af fald-energien, for derved at beskytte det følsomme udstyr. Det er herunder af væsentlig betydning, at forhøjningerne har en hensigtsmæssig "sammenpresningskarak-teristik", idet de skal være tilstrækkeligt stive til ikke 25 at blive deformeret ved belastninger inden for det tilladte, men på den anden side skal de kunne give efter ved kraftige stødbelastninger, for derved at forhindre, at hele stødenergien overføres til det emballerede udstyr og beskadiger dette. De ovenfor omtalte, kendte emballageemner kan ikke 30 opfylde dette ønske, eftersom de ved sammenpresning ud over den normale bæreevne vil klappe helt sammen uden at optage stød-energi i nogen udstrækning af betydning. Med henblik på at opnå den ønskede virkning, er emballageemnet ifølge opfindelsen først og fremmest ejendommeligt ved den udform-35 ning, der er angivet i den kendetegnende del af krav 1.When an article packaged in this way is subjected to harsh treatment, e.g. in the event of a fall on a hard surface, the elevations in the blank must be able to absorb at least part of the fall energy, thereby protecting the sensitive equipment. It is essential here that the elevations have an appropriate "compression characteristic" as they must be sufficiently rigid so as not to be deformed by loads within the permissible, but on the other hand they must be able to give in to heavy impact loads. , thereby preventing the entire impact energy from being transferred to the packaged equipment and damaging it. The above-mentioned known packaging blanks may not fulfill this desire, since when compressed beyond the normal load capacity they will collapse completely without absorbing shock energy to any significant extent. In order to obtain the desired effect, the package blank according to the invention is first and foremost peculiar to the design according to the characterizing part of claim 1.
DK 168279 B1 2DK 168279 B1 2
Ved at vælge en vinkel inden for det angivne interval opnås, at når hver forhøjnings grænsestyrke - svarende til den største kraft, den kan tåle uden at blive deformeret -overskrides, vil forhøjningerne blive sammenpresset, mens 5 de under optagelse af stødenergien yder en i hovedsagen konstant modkraft, uden at klappe sammen, således at de på ethvert stadium under sammenpresningen vedblivende har den samme grænsestyrke. På grund af fiberpulpmaterialets iboende egenskaber vil der herved ske en blivende deformering, så-10 ledes at man ved åbning af emballagen vil kunne konstatere, at det emballerede udstyr har været udsat for inertikræfter af størrelse som forhøjningernes deformeringsmodstand.By selecting an angle within the specified range, it is obtained that when the boundary strength of each elevation - corresponding to the greatest force it can withstand without being deformed - is exceeded, the elevations will be compressed while the constant counter force, without collapsing, so that they have the same limit strength at any stage during the compression. Due to the inherent properties of the fiber pulp material, there will thereby be permanent deformation, so that upon opening the packaging it will be found that the packaged equipment has been subjected to inertia forces of size as the deformation resistance of the elevations.
En yderligere sikkerhed imod sammenklapning af forhøjningerne 15 kan opnås ved eri udførelsesform for emballageemnet ifølge opfindelsen, der er angivet i krav 2.A further security against collapse of the elevations 15 can be achieved by an embodiment of the packaging blank according to the invention as set forth in claim 2.
Ved hjælp af de ovenfor omtalte foranstaltninger er der opnået en styret plastisk deformering af forhøjningerne, 20 når disse belastes ud over en bestemt grænseværdi. Det kan imidlertid være hensigtsmæssigt at udforme forhøjningerne på en sådan måde, at de også giver mulighed for en indledende elastisk deformation, idet det herved bl.a. sikres, at emballageemnet ligger indspændt mellem den emballerede genstand 25 og den ydre emballage, i stedet for at ligge løst og "klapre" mellem disse. En sådan indledende elastisk de formering opnås ved den udførelsesform for emballageemnet ifølge opfindelsen, der er angivet i krav 3. Herved udnyttes et princip, der kendes fra FR-patentskrift nr. 2.177.131, hvori der beskrives 30 et emballageemne af plast, f.eks. PVC, med et antal fremspring i form af afkortede kegler med trappeformede sideflader, hvori "indtrinene", dvs. de plane dele, fungerer som membran- eller tallerkenfjedre.By means of the above-mentioned measures, a controlled plastic deformation of the elevations has been achieved when these are loaded beyond a certain limit value. However, it may be appropriate to design the elevations in such a way that they also allow for an initial elastic deformation. ensure that the packaging blank is clamped between the packaged article 25 and the outer packaging, rather than being loose and "clattering" between them. Such initial elastic deformation is achieved by the embodiment of the packaging blank according to the invention set forth in claim 3. This utilizes a principle known from FR patent specification No. 2,177,131, which describes a plastic packaging blank, f. eg. PVC, with a plurality of projections in the form of truncated cones with stair-shaped side surfaces, wherein the "steps", ie. the flat parts, act as diaphragm or plate springs.
35 Opfindelsen skal i det følgende forklares nærmere under henvisning til tegningen, på hvilken DK 168279 B1 3 fig. 1 viser et udførelseseksempel på et emballageemne ifølge opfindelsen, set mod en fladside, 5 fig. 2 er et snit efter linien II-II i fig. 1, fig. 3 er et snit efter linien III-III i fig. 1, fig. 4 viser den ene ende af det i fig. 1-3 viste embal-10 lageemne i den tilstand, hvor emnet er sammenfoldet til dannelse af en sidebeskytter for et elektronisk apparat, der skal emballeres i en papkasse eller lignende, delvis i snit efter linien IV-IV i fig. 5, 15 fig. 5 er et del-snit efter linien v-v i fig. 4, fig. 6 er et snit efter linien VI-VI i fig. 4 og viser emballageemnet i brug ved emballering af en videobåndoptager, 20 fig. 7-9 er tre del-snit svarende stort set til den midterste del af fig. 3 gennem en af emballageemnets lommer, og viser dels en ændret udformning af lommen, dels hvorledes lommen sammenpresses under en stor belastning, og 25 fig. 10 er et snit efter linien X-X i fig. 7.The invention will now be explained in more detail with reference to the drawing, in which FIG. 1 shows an exemplary embodiment of a packaging blank according to the invention, viewed against a flat side; FIG. 2 is a section along line II-II of FIG. 1, FIG. 3 is a sectional view taken along line III-III of FIG. 1, FIG. 4 shows one end of the one shown in FIG. 1-3, in the condition where the blank is folded to form a side protector for an electronic device to be packaged in a cardboard box or the like, partially in section along the line IV-IV of FIG. 5, FIG. 5 is a sectional view taken along the line v-v of FIG. 4, FIG. 6 is a section on the line VI-VI of FIG. 4 and showing the packaging blank in use when packaging a VCR; FIG. 7-9 are three sectional sections corresponding substantially to the middle portion of FIG. 3 through one of the pockets of the packaging blank, showing partly a changed shape of the pocket and partly how the pocket is compressed under a large load, and FIG. 10 is a section along the line X-X of FIG. 7th
Det i fig. 1-4 viste udførelseseksempel på et emballageemne ifølge opfindelsen, som i lighed med de øvrige her omtalte udførelseseksempler tænkes fremstillet på lignende måde som 30 de velkendte ægemballager, f.eks. ægbakker og ægkartoner af fiberpulpmateriale, dvs. ved påsugning af fiberpulplag på en sugeform, omfatter en stort set plan kropdel 1, hvorpå der er udformet et antal fremspring 2-5 af tildels forskellig udformning, som i forhold til kropdelen 1 kan betegnes som 35 forhøjninger eller fordybninger, afhængigt af, hvorvidt man betragter emnet fra den samme side som vist i fig. 1 eller DK 168279 B1 4 fra den modsatte side. På grund af fremstillingsmetoden er vægtykkelsen i kropdelen 1 og fremspringene 2-5 af samme størrelsesorden, i praksis normalt mellem 1 og 3 mm. For bekvemheds skyld vil samtlige af disse fremspring i det 5 følgende blive betegnet som lommer, og hvorvidt de skal betragtes som forhøjninger eller fordybninger vil fremgå af sammenhængen.The FIG. 1-4 illustrates an embodiment of a packaging item according to the invention, which, like the other embodiments mentioned herein, is thought to be manufactured in a similar manner to the well known egg packaging, e.g. egg trays and egg cartons of fibrous pulp material, viz. by suction of fiber pulse layers on a suction mold, comprises a substantially planar body portion 1, on which are formed a number of projections 2-5 of partly different shapes, which in relation to the body portion 1 may be referred to as 35 elevations or depressions, depending on whether one is considers the subject from the same side as shown in FIG. 1 or DK 168279 B1 4 from the opposite side. Because of the manufacturing method, the wall thickness of the body part 1 and the projections 2-5 are of the same order of magnitude, in practice usually between 1 and 3 mm. For convenience, all of these projections will hereinafter be referred to as pockets, and whether or not they are to be considered elevations or recesses will appear in the context.
Lommerne 2-5 udgøres således af 10 - et antal midterlommer 2 beliggende i rækker på midter linien af kropdelen 1, : - to sæt sidelommer 3, der er anbragt langs med hver sin af to sidedele 6 og 7, der er udformet i fortsættelse af kropdelen 1 og i den i fig. 1-3 viste situa-15 tion flugter med denne, to større endelommer 4, der er udformet på endedele 8, der er udformet i fortsættelse af sidedelen 6 og i den i fig. 1-3 viste situation flugter med denne, og 20 - to mindre endelommer 5, der er udformet på endedele 9, der er udformet i fortsættelse af sidedelen 7 og i den i fig. 1-3 viste situation flugter med denne.The pockets 2-5 are thus made up of 10 - a number of center pockets 2 located in rows on the center line of the body part 1: - two sets of side pockets 3 arranged along each of two side portions 6 and 7, which are formed in continuation of the body part 1 and in the embodiment of FIG. 1-3 are flush with this, two larger end pockets 4 formed on end portions 8 formed in continuation of the side portion 6 and in the embodiment of FIG. 1-3 are flush with this, and 20 - two smaller end pockets 5 formed on end portions 9 formed in continuation of the side portion 7 and in the embodiment of FIG. 1-3 shows a situation flush with this one.
Det i fig. 1-3 viste udførelseseksempel på et emballageemne 25 er først og fremmest bestemt til anvendelse som sidebeskytter for en videomaskine til hjemmebrug, som i det foreliggende 1 tilfælde er udformet som en lukket, flad kasse. Når det viste emballageemne er anbragt som sidebeskytter på et sådant apparat, forløber kropdelen 1 i berøring med og langs med 30 apparatets ene langside, idet sidedelene 6 og 7 er bukket om og derved berører oversiden henholdsvis undersiden, mens endedelene 8 og 9 igen er bukket om fra sidedelene 6 henholdsvis 7 og berører apparatets to endeflader. Med henblik på tilpasning til apparater af forskellige højde er embal-35 lageemnet forsynet med to sæt foldelinier, nemlig et sæt minimumsfoldelinier 10 og 11 og et sæt maksimumsfoldelinier 5 DK 168279 B1 12 og 13, bestemt til foldning af emnet med henblik på samvirke med et apparat af forholdsvis mindre henholdsvis forholdsvis større højdedimension.The FIG. 1-3 of an embodiment of a packaging blank 25 are primarily intended for use as a side guard for a home-use video machine, which in the present case is designed as a closed, flat box. When the shown blank is placed as a side guard on such an apparatus, the body portion 1 extends into contact with and along one long side of the apparatus, the side portions 6 and 7 being bent and thereby touching the upper and lower sides respectively, while the end portions 8 and 9 being bent again. about from the side portions 6 and 7, respectively, and touching the two end faces of the apparatus. For the purpose of adaptation to appliances of different heights, the packaging blank is provided with two sets of fold lines, namely a set of minimum fold lines 10 and 11 and a set of maximum fold lines 5 DK 168279 B1 12 and 13, intended for folding the blank for co-operation with a apparatus of relatively smaller and relatively larger height dimensions.
5 Som vist i fig. 4 er sidedelene 6 og 7 bukket gennem 90® i forhold til kropdelen 1 omkring maximumsfoldelinierne 12, mens endedelene 8 og 9 er bukket gennem ligeledes 90° omkring minimumsfoldelinierne 11 i forhold til sidedelene 6 henholdsvis 7; som det vil fremgå af fig. 4, vil det være nød-10 vendigt at bukke endedelen 9 først, eftersom den på endedelen 8 udformede større endelomme 4 skal passe uden på den mindre endelomme 5 på endedelen 9.5 As shown in FIG. 4, the side portions 6 and 7 are bent through 90 ° relative to the body portion 1 around the maximum fold lines 12, while the end portions 8 and 9 are also bent through 90 ° around the minimum fold lines 11 relative to the side portions 6 and 7, respectively; as will be seen in FIG. 4, it will be necessary to bend the end portion 9 first, since the larger end pocket 4 formed on the end portion 8 must fit outside the smaller end pocket 5 of the end portion 9.
Som det vil kunne ses af fig. 3 og 5, danner de vægge i 15 endelommerne 4 og 5, som i den i fig. 4 viste situation står i friktions indgreb med hinanden, en vinkel 14 med hinanden. Ved materialer af den her omhandlede art har det vist sig hensigtsmæssigt at vælge en vinkel 14 på ca. 30®.As will be seen from FIG. 3 and 5, they form the walls of the end pockets 4 and 5, as in the embodiment of FIG. 4 is engaged in frictional engagement with one another, an angle 14 with each other. With materials of this kind it has been found appropriate to choose an angle 14 of approx. 30®.
Af produktionsmæssige hensyn har det vist sig hensigtsmæssigt 20 at udforme samtlige sideflader på samtlige lommer 2-5 med denne indbyrdes vinkel på ca. 30® med de pågældende grundflader. Vinklen 14 er valgt under hensyn til to indbyrdes modstridende ønsker, nemlig for det første, at i den i fig. 4 viste situation 25 skal de mindre endelommer 5 indgribe så fast med de større endelommer 4, at disse dele ikke løsner fra hinanden, dels på grund af den tilbageværende elasticitet i foldelinierne, dels på grund af belastning under almindelig håndtering af emballageemnet, her-30 under påsætning af dette som sidebeskytter på det apparat, der skal emballeres, og - for det andet, at ikke-bukkede emballageemner af den i·fig. 1-3 viste udformning skal kunne stables oven på hinanden, uden at de derved kommer til at sidde 35 så fast sammen, at det er umuligt at udtage enkelte emner fra stablen.For production reasons, it has proved convenient to design all side surfaces of all pockets 2-5 with this mutual angle of approx. 30® with the relevant ground surfaces. The angle 14 is chosen taking into account two contradictory desires, namely, firstly, that in the embodiment shown in FIG. 4, the smaller end pockets 5 must engage so firmly with the larger end pockets 4 that these parts do not detach from each other, partly because of the remaining elasticity of the fold lines and partly because of stress during ordinary handling of the packaging material, here 30 applying this as a side guard to the apparatus to be packaged; and - secondly, that non-bent packing items of the type shown in FIG. 1-3, it must be possible to stack one another on top of each other without thereby getting them stuck together so that it is impossible to remove individual items from the stack.
DK 168279 B1 6DK 168279 B1 6
Det har ved anvendelse af det her omtalte materiale vist sig, at denne vinkel bør være mindst 20e og højst 40°, for at disse betingelser skal kunne opfyldes.It has been found, using the material referred to herein, that this angle should be at least 20e and not more than 40 ° in order for these conditions to be met.
5 Det skal i øvrigt bemærkes, at de to indbyrdes indgribende lommer 4 og 5, der er vist i fig. 4, tilsammen har en styrke svarende til to lommer. Herved opnås en ekstra beskyttelse i et område, der kan være særligt udsat.5 It should also be noted that the two interlocking pockets 4 and 5 shown in FIG. 4, together have a strength corresponding to two pockets. This provides additional protection in an area that may be particularly exposed.
10 Fig. 6 viser, hvorledes en videobåndoptager 29, hvoraf kun en langsidedel er skematisk antydet, ved hjælp af midterlommerne 2 og sidelommerne 3 støttes imod indersiden af en bølgepapkasse 30. For at gøre lettere at føre emballageemnet og videobåndoptageren sammen til den i fig. 6 viste indbyrdes 15 stilling, er der på de frie kanter af sidedelene 6 og 7 udformet indstyringslæber 31. Disse kan enten dannes under selve støbeoperationen, eller ved den efterpresning, der bl.a. kan omfatte prægning af foldelinieme, afklipning af grater mv.FIG. 6 shows how a videotape recorder 29, of which only one longitudinal portion is schematically indicated, is supported by the middle pockets 2 and the side pockets 3 against the inside of a corrugated cardboard box 30. In order to facilitate carrying the packaging item and the video recorder together with the one in fig. 6, the guide lips 31 are formed on the free edges of the side parts 6 and 7. These can be formed either during the casting operation itself or by the post-pressing which, among other things, occurs. may include embossing of folding lines, cutting of burrs, etc.

Den lomme 15, der er vist i fig. 7-10, er i grove træk udformet som lommerne 2 og 4 i det i fig. 1-6 viste udførelseseksempel, men adskiller sig fra disse, dels, ved at samtlige sidevægge er krumme med konvek-25 siteten vendende udad, og dels, ved at den er udformet med henblik på en delvis elastisk, delvis plastisk eftergivenhed.The pocket 15 shown in FIG. 7-10, are roughly formed as pockets 2 and 4 in the embodiment of FIG. 1-6, but differs from these, partly in that all sidewalls are curved with the convexity facing outwards, and partly in that it is designed for a partially elastic, partially plastic yield.
Lommen 15 omfatter således 30 - et svøb 16, der som det fremgår af fig. 10 er krumt hele vejen rundt med varierende krumning til dannelse af sidefladen i en "afrundet rektangulær pyramide", idet svøbet 16 strækker sig fra grundmaterialet, som - her udgøres af kropdelen 1 eller endedelen 8 som 35 vist i fig. i, til en bundvæg 17, der består af en rundtgående randdel \ 7 DK 168279 B1 18, der omgiver en midt på bundvæggen anbragt støtteknop 19.The pocket 15 thus comprises 30 - a wrapper 16 which, as shown in FIG. 10 is curved all the way around with varying curvature to form the side surface of a "rounded rectangular pyramid", the scoop 16 extending from the base material, which - here constitutes the body part 1 or the end part 8 as shown in FIG. i, to a bottom wall 17 consisting of a circumferential rim portion 7 surrounding a support knob 19 disposed in the middle of the bottom wall.
Ved belastning inden for et begrænset kraftområde vil rand-5 delen 18 som antydet i fig. 8 fungere som en art tallerkenfjeder, der f.eks. kan udnyttes til at fastspænde emballageemnet "raslefrit" mellem den emballerede genstand, f.eks. den i fig. 6 viste videobåndoptager 29, og den ydre emballage, f.eks. den ligeledes i fig. 6 viste bølgepapkasse 30.When loaded within a limited force range, the rim portion 18, as indicated in FIG. 8 act as a kind of plate spring which e.g. may be utilized to clamp the packing blank "rattle-free" between the packaged article, e.g. FIG. 6, and the outer packaging, e.g. it is also shown in FIG. 6 corrugated cardboard box 30.
1010
Dersom belastningen på lommen 15 forøges ud over det nævnte begrænsede kraftinterval, og randdelen 18 giver så meget efter, at svøbet 16 påvirkes direkte, vil der ske en fremadskridende plastisk deformering af svøbet 16 til dannelse af 15 "harmonikafolder" 20 som antydet i fig. 9. Ved passende valg af vinklen 21 mellem de to modstående dele af svøbet 16 vil der blive skabt optimale forudsætninger for dannelse af sådanne harmonikafolder, hvis fremadskridende dannelse har vist sig at bevirke, at fortsat sammenpresning af svøbet 20 16 vil ske uden mærkbar forøgelse af sammenpresningskraften, og også uden at svøbet på noget tidspunkt klapper sammen og taber sin støtteevne.If the load on the pocket 15 is increased beyond the said limited force interval, and the rim portion 18 gives so much after the scoop 16 is directly affected, a progressive plastic deformation of the scoop 16 will occur to form 15 "harmonic folds" 20 as indicated in FIG. 9. By appropriate selection of the angle 21 between the two opposite portions of the shroud 16, optimum conditions will be created for the formation of such harmonic folds, whose progressive formation has been shown to cause continued compression of the shroud 20 16 to occur without appreciable increase of the compressive force, and also without the scrap at any point collapses and loses its supporting ability.
Foruden valg af vinklen 21 inden for et optimalt interval 25 udgør den i fig. 10 viste krumme udformning af svøbet 16 et bidrag til at undgå, at svøbet 16 klapper sammen som nævnt ovenfor. Selv om de stort set plane sidevægge i de forskellige lommer 2-5, der er vist i fig. 1-6, i de aller fleste tilfælde udviser en minimal tilbøjelighed til sammenklapning 30 under belastning af den her omtalte art, yder den i fig. 10 viste krumme udformning af sidevæggene en yderligere sikkerhed mod sådan sammenklapning.In addition to selecting the angle 21 within an optimal range 25, the one shown in FIG. 10, the curved configuration of the cover 16 is shown to help prevent the cover 16 from collapsing as mentioned above. Although the substantially flat side walls of the various pockets 2-5 shown in FIG. 1-6, in the vast majority of cases, exhibit a minimal tendency for collapse 30 under load of the kind referred to herein, it provides in FIG. 10 shows a further security against such collapse.
De indtil nu indvundne erfaringer har vist, at ved anvendelse 35 af sædvanligt pulpmateriale fremstillet ud fra affaldspapir, bør vinklen 21 ligge i området mellem 20° og 40°, idet en DK 168279 B1 8 vinkel på ca. 30° forekommer at være mest hensigtsmæssig med henblik på at sikre, at den plastiske deformering af svøbet 16 sker som antydet i fig. 9, uden risiko for sammenklapning.Experience gained hitherto has shown that when using 35 ordinary pulp material made from waste paper, the angle 21 should be in the range between 20 ° and 40 °, with an angle of approx. 30 ° appears to be most appropriate in order to ensure that the plastic deformation of the shell 16 occurs as indicated in FIG. 9, without the risk of collapse.
Som det vil ses, svarer dette foretrukne vinkel interval og 5 denne foretrukne vinkel til det vinkelinterval henholdsvis den vinkel, der som nævnt i det foregående udgør det bedste kompromis mellem på den ene side den indbyrdes låseevne hos endelommerne 4 og 5 og på den anden side muligheden for at udtage de enkelte emballageemner fra en stabel. Det er imid-10 lertid sandsynligt, at dette sammenfald ikke vil forekomme ved emballageemner, som blot er ændret ganske lidt i forhold til det viste eksempel.As will be seen, this preferred angle range and 5 this preferred angle correspond to the angle range and angle, respectively, which, as mentioned above, constitute the best compromise between, on the one hand, the interlocking capability of the end pockets 4 and 5 and on the other hand. the ability to extract individual packaging items from a stack. However, it is likely that this coincidence will not occur with packaging items which have changed only slightly in relation to the example shown.
Den omtalte fiberpulp kan være fremstillet af f.eks. plan-15 tefibermasse, især træmasse, eller papirmasse, herunder genbrugs-papirmasse.The said fiber pulp may be made of e.g. planar fiber pulp, especially wood pulp, or pulp, including recycled pulp.
