Abstract

A crate 1 for bottles with cylindrical body portions has double-skinned corner portions 7 which define with portions 13 of an internal partitioning grid 5 corner compartments 6a for bottles. The inner skin 12 of the corner portion is formed with vertical ribs 14 adjacent the grid portions 13. These ribs, which are interconnected with the outer skin 8 of the corner portion to form hollow columns 14a therewith, strengthen the corner portions and allow the spacing of the skins thereof to be reduced so that the size of the compartment can be increased for given external crate dimensions, and as the ribs are located adjacent the partitioning portions 13 they occupy space which would otherwise be free and do not reduce the effective size of the corner compartments.

Den foreliggende opfindelse angår en i det væsentlige rektangulær stablelig plastkasse af den i indledningen til krav 1 angivne art.The present invention relates to a substantially rectangular stackable plastic box of the kind set forth in the preamble of claim 1.

En sådan stablelig plastkasse til flasker er 5 eksempelvis omhandlet i DE offentliggørelsesskrift nr.Such a stackable plastic box for bottles is disclosed, for example, in DE publication no.

2 432 881, hvilken kasse under bunden er forsynet med kantdele, der ved stabling er indrettet til at indgribe på en sådan måde i det frie rum foroven i en anden lignende kasse,' ovenpå hvilken kassen stables, at kasserne 10 ikke kan forskydes i forhold til hinanden. Kasser af denne art kan således kun stables ovenpå hinanden i lodrette søjler, og højt stablede kasssøjler af sådanne kasser vil være ustabile og tilbøjelige til at vælte.2,432,881, the box below the bottom being provided with edge portions adapted to stack in such a manner in the free space at the top of another similar box, on top of which the box is stacked that the boxes 10 cannot be displaced in relation to to each other. Thus, boxes of this kind can only be stacked on top of each other in vertical columns, and highly stacked box columns of such boxes will be unstable and prone to tipping over.

15 Det er formålet for den foreliggende opfindelse at tilvejebringe en plastkasse af den anførte art, der ikke blot kan stables i lodrette søjler med de enkelte kasser anbragt direkte ovenpå hinanden, men som tillige kan stables i "forbandt", dvs. således, at en 20 kasse i stabelen er anbragt ovenpå og indgriber i to kasser af samme art, hvorved stablingen bliver væsentlig mere stabil, idet plastkassen tillige skal have en sådan stivhed og mekanisk styrke, som tillader stabling af et antal fyldte kasser ovenpå hinanden.It is the object of the present invention to provide a plastic box of the kind mentioned which can not only be stacked in vertical columns with the individual boxes placed directly on top of each other, but which can also be stacked in "connected", i.e. so that a box in the stack is placed on top and engages in two boxes of the same kind, thereby making the stacking considerably more stable, the plastic box also having such rigidity and mechanical strength which allows stacking of a number of filled boxes on top of one another.

25 Dette opnås ifølge opfindelsen ved det i den kendetegnende del af krav 1 angivne, idet en plastkasse ifølge opfindelsen herved ikke blot kan stables lodret ovenpå en tilsvarende kasse, men tillige kan stables således ovenpå to sådanne kasser, at den enten’ 30 er midtstillet i forhold til disse, eller dækker tre fjerdedel over den ene af disse kasser og en fjerdedel over den anden, ligesom der også er mulighed for, at en kasse ifølge opfindelsen kan stables på tværs over to ved siden af hinanden anbragte kasser af samme art.This is achieved according to the invention by the characterizing part of claim 1, wherein a plastic box according to the invention can thereby not only be stacked vertically on top of a corresponding box, but also can be stacked on top of two such boxes so that it is either centered in or cover three-quarters over one of these boxes and one-fourth over the other, as well as the possibility that a box according to the invention can be stacked across two adjacent boxes of the same kind.

35 Dette er en klar fordel ved anbringelsen af mange kasser for eksempel i et lagerrum, idet kasserne herved 2This is a clear advantage of placing many boxes, for example, in a storage room, the boxes thereby 2

på* flere måder kan stables i "forbandt", hvilket på afgørende måde forøger stabiliteten af kassestabelen og praktisk talt eliminerer risikoen for, at de stablede kasser skulle kunne vælte.in * several ways can be stacked in "connected", which significantly increases the stability of the box stack and virtually eliminates the risk that the stacked boxes could topple over.

5 Yderligere foretrukne træk hos plastkassen ifølge opfindelsen er angivet i de uselvstændige krav.Further preferred features of the plastic box of the invention are set forth in the dependent claims.

Opfindelsen skal i det følgende beskrives nærmere ud fra en udførelsesform, idet der henvises til tegningen, på hvilken 10 fig. 1 viser en flaskekasse, idet højre side af figuren er en planprojektion, set fra neden, og venstre side af figuren viser et delvis snit, set fra oven, langs linien A - A i fig. 2, fig. 2 kassen set fra siden og delvis i snit langs 15 linien B - B i fig. 1, og fig. 3 delvis i snit langs linien C - C i fig. 1 kassen set fra enden.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail from an embodiment, with reference to the drawing, in which: FIG. 1 shows a bottle box, the right side of the figure being a plan view from below, and the left side of the figure showing a partial sectional view, taken along line A - A of FIG. 2, FIG. 2 shows the box in side view and partly in section along the line B - B in FIG. 1, and FIG. 3 partly in section along the line C - C in FIG. 1 box seen from the end.

På tegningen er vist en i det væsentlige rektangulær ^ kasse 1 til et antal ikke viste flasker med cylindrisk hoveddel. Kassen 1 har en bund 2 og et sidevægsorgan 3, som er udformet med en dobbeltvæg, der strækker sig opad fra bunden til en øvre kant 4 langs kassens åbne top. Et indre delegitter 5 er anbragt med henblik på at danne rum 6 inden i kassen, idet hver flaske får sit rum.The drawing shows a substantially rectangular box 1 for a number of cylindrical body bottles not shown. The box 1 has a bottom 2 and a side wall member 3 which is formed with a double wall extending upwards from the bottom to an upper edge 4 along the open top of the box. An inner delegate 5 is arranged to form space 6 inside the box, each bottle being given its space.

Sidevægsorganet omfatter dobbeltvæggede hjørnedele 7, som bedst ses i snittet i fig. 1, hver af disse omfatter en ydervæg 8 med på hinanden vinkelret stående dele 9 og 18, som i den viste kasse er forbundet med en buet del 11, og en indervæg 12, som ligger i en vis afstand fra ydervæggen 8.The sidewall means comprises double-walled corner portions 7, which are best seen in the section of FIG. 1, each of these comprises an outer wall 8 with mutually perpendicular portions 9 and 18 connected to a curved portion 11 in the box shown, and an inner wall 12 located at a certain distance from the outer wall 8.

Hver hjørnedel 7 danner sammen med tilstødende og på hinanden vinkelret stående dele 13 af delegitteret 5 et hjørnerum 6a til én af flaskerne, og indervæggen 12 er op til hver af disse dele 13 af delegitteret udformet med en ribbe 14, som 35Each corner portion 7 together with adjacent and mutually perpendicular portions 13 of the delegate 5 forms a corner space 6a for one of the bottles, and the inner wall 12 is up to each of these portions 13 of the delegate formed with a rib 14 which

strækker sig bort fra ydervæggen 8 og vinkelret på bunden 2. Ribberne strækker sig fra bunden 2 og ender nær den øvre kant 4. Ribberne 14 er forbundet med ydervæggen 8, så der dannes hule søjler 14a, som strækker sig lodret op fra bunden 2. I den 5 viste kasse er ribberne 14 i hver hjørnedel kun forbundet med ydervæggen 8 ved hjælp af afstivningsorganer 24 i deres fjerneste hjørnedele, sådan at hjørnedelen er fuldstændig hul. Som det fremgår af cirklerne 15, som er tegnet i fig. 1 for at vise tværsnittet af to flaskers hoveddele, formindsker anbringelsen 10 af ribberne 14 op til gitterdelene 13 ikke rummenes effektive størrelse, samtidig med at de forstærker hjørnedelene, fordi den plads ribberne optager i rummene ellers ville være tom. Ribbernes forstærkende virkning bevirker, at afstanden mellem hjørnedelenes indre og ydre væg kan reduceres, uden 15 at det påvirker hjørnedelenes samlede styrke, og størrelsen af rummet kan således forøges.extending from the outer wall 8 and perpendicular to the bottom 2. The ribs extend from the bottom 2 and end near the upper edge 4. The ribs 14 are connected to the outer wall 8 to form hollow columns 14a extending vertically from the bottom 2. In the box 5 shown, the ribs 14 in each corner portion are connected only to the outer wall 8 by means of stiffening means 24 in their farthest corner portions such that the corner portion is completely hollow. As can be seen from the circles 15 shown in FIG. 1 to show the cross-section of the main parts of two bottles, the placement 10 of the ribs 14 up to the grid members 13 does not reduce the effective size of the rooms while reinforcing the corner portions because the space the ribs occupy in the spaces would otherwise be empty. The reinforcing effect of the ribs means that the distance between the inner and outer walls of the corner parts can be reduced without affecting the overall strength of the corner parts, and thus the size of the space can be increased.

Skønt det kan være fordelagtigt at lade indervæggen fjerne sig fra ydervæggen fra den øvre kant 4 med henblik på at skabe en stivere konstruktion og på at lette støbningen, 20 kan den afstand mellem nabohjørnedele, som er til rådighed for inddeling i rum med givne ydre kassedimensioner, forøges ved at udføre indervæggen parallel med eller i det væsentlige parallel med ydervæggen i det mindste ved hjørnerummenes lodrette midterplaner. Måske kræves denne forøgelse imid-25 lertid kun i én retning, f.eks. i retning af kassens langsider, og som det fremgår af den viste kasse, kan dette opnås ved kun at udforme indervæggen parallelt med ydervæggen ved det lodrette midterplan, som går gennem kassens korte sider - planet D - D gennem rummet 6a i fig. 1.Although it may be advantageous to remove the inner wall from the outer wall from the upper edge 4 in order to create a stiffer construction and to facilitate casting, the distance between adjacent corner parts available for division into spaces with given outer box dimensions may , is increased by conducting the inner wall parallel to or substantially parallel to the outer wall at least at the vertical median planes of the corner spaces. However, this increase may be required in only one direction, e.g. in the direction of the long sides of the box, and as can be seen from the box shown, this can be achieved by forming only the inner wall parallel to the outer wall at the vertical median plane passing through the short sides of the box - the plane D - D through the space 6a in fig. First

30 Hjørnedelenes styrke kan hensigtmæssigt forøges yder ligere som vist for den afbildede kasse ved at udforme indervæggen 12, som ligger over for den buede del 11 af ydervæggen, som en bue, der har større krumningsradius og strækker sig over et større stykke end delen 11 med henblik på at forøge 35 afstanden mellem væggene. Det er igen fordelagtigt, at dette ikke indskrænker hjørnerummenes effektive størrelse.Conveniently, the strength of the corner portions may be further enhanced as shown for the depicted box by forming the inner wall 12, which faces the curved portion 11 of the outer wall, as an arc having a greater radius of curvature and extending over a larger portion than the portion 11 by in order to increase the distance between the walls. Again, it is advantageous that this does not limit the effective size of the corner rooms.

Sidevægsorganerne omfatter dobbeltvæggede sidedele, som strækker sig mellem hjørnedelene 7. De lange og korte sidedele er på tegningen angivet med henholdsvis 16 og 17. Disse sidedele omfatter yder- og indervægge, henholdsvis 18 og 19. Dele-5 gitteret 5 omfatter dele 20, som strækker sig mod vægdelene, og som det fremgår af ovenstående beskrivelse, er det fordelagtigt, at sidedelene kan forstærkes ved hjælp af ribber, som ribberne 14, op til én eller flere af gitterdelene 20. I den viste udførelse er en sådan ribbe 21 udformet midtvejs i hver 10 af de længste sidedele.The sidewall members comprise double-walled side portions extending between the corner portions 7. The long and short side portions are indicated in the drawing by 16 and 17. These side portions comprise outer and inner walls, respectively, 18 and 19. Parts 5 of the grid 5 comprise portions 20 which extending to the wall portions, and as will be apparent from the foregoing description, it is advantageous that the side portions may be reinforced by ribs, such as the ribs 14, up to one or more of the grid portions 20. In the embodiment shown, such rib 21 is formed midway. in every 10 of the longest side sections.

Åbninger 22 gennem sidevægsorganerne 3 danner håndtag for kassen, og bortset fra disse åbninger 22 og udsparinger 23, som er udformet over disse, er kassens ydre, som dannes af ydervæggene 8 og 18, jævn og ubrudt. Hjørnedelen 7's 15 indervægge 12 er ligeledes ubrudte, men sidedelenes indervægge 19, som også er forbundet med disses ydervægge 18 ved hjælp af afstivningsorganer 24, som strækker sig mellem inder- og ydervæggene og forstærker konstruktionen, er forsynet med åbninger. De lange sidedeles indervægge er vist med i det 20 væsentlige rektangulære åbninger 25, som strækker sig mellem sidedelens Øvre og nedre bånd således, at de lange sidedele sammenhængende er dobbeltvæggede ved deres top og bund. De korte sidedeles indervægge er forsynet med åbninger 26, som strækker sig fra bunden af indervæggene og ender kort før 25 åbningerne 22. Udformningen af åbningerne giver en væsentlig materialebesparelse og kan udføres uden at forringe sidedelskonstruktionens styrke væsentligt.Openings 22 through the sidewalls 3 provide handle for the box, and apart from these openings 22 and recesses 23 formed thereon, the exterior of the box formed by the outer walls 8 and 18 is smooth and unbroken. The inner walls 12 of the corner part 7 are also unbroken, but the inner walls 19 of the side parts, which are also connected to their outer walls 18 by means of stiffening means 24 which extend between the inner and outer walls and reinforce the structure, are provided with openings. The inner side walls of the long side portions are shown with substantially rectangular openings 25 extending between the upper and lower bands of the side portions such that the long side portions are contiguously double-walled at their top and bottom. The inner side walls of the short side are provided with openings 26 which extend from the bottom of the inner walls and end shortly before the openings 22. The design of the openings provides a substantial saving of material and can be carried out without significantly impairing the strength of the side part construction.

Kassens bund 2 er også forsynet med åbninger og er vist som et tremmegitter, der er forsynet med et antal nedad-30 rettede fremspring 27, som er vist anbragt i tre rækker og fire søjler, idet naborækker Og -søjler mellem sig danner kanaler henholdsvis 28 (fig. 3) og 29 (fig. 2). Hver kanal har en sådan bredde, at de øvre kanter 4 af sidedelene på to ens kasser, som er anbragt ved siden af hinanden og stablet oven 35 på kassen, kan anbringes heri, hvor de øvre kanter 4, som detThe bottom 2 of the box is also provided with openings and is shown as a lattice grille provided with a number of downwardly projecting projections 27 which are shown arranged in three rows and four columns, with adjacent rows and columns forming channels respectively 28 (Fig. 3) and 29 (Fig. 2). Each channel has a width such that the upper edges 4 of the side portions of two identical boxes arranged side by side and stacked on top of the box can be placed therein, the upper edges 4 being

Denne foranstaltning muliggør, at kasserne kan stables på anden måde end direkte lige lodret over hinanden og giver mulighed for en stabil stabling.This measure allows the boxes to be stacked in a manner other than directly equal to one another vertically and allows for stable stacking.

5 Som det bedst fremgår af fig. 1, ligger hjørnedelenes ribber 14 fordelagtigt op til kanalerne 28's og de ydre af kanalerne 29's sider, og de lange sidedeles ribber 21 er anbragt midt i den midterste kanal 29. Når kasserne er stablet på den ovenfor beskrevne måde, strækker ved siden af hinanden 10 anbragte, nedre kassers mod hinanden og i en kanal 28 eller 29 beliggende øvre kanter sig tæt på eller direkte ind under en ribbe 14 eller 21 i hver ende af kanalen. Denne indretning giver kasserne i en stabels nederste lag bedre mulighed for at bære belastningen fra stabelen.5 As best seen in FIG. 1, the ribs 14 of the corner portions are advantageously adjacent to the sides of the channels 28 and the outer sides of the channels 29, and the ribs 21 of the long side portions are placed in the middle of the middle channel 29. When the boxes are stacked in the manner described above, they extend side by side 10. disposed lower boxes facing each other and in the upper edges of a channel 28 or 29 close to or directly under a rib 14 or 21 at each end of the channel. This arrangement allows the crates in the bottom layer of a stack to better carry the load from the stack.

15 Den viste kasse er sprøjtestøbt af et plastmateriale med delegitteret 5 støbt i ét stykke med sidevægsorganerne.The box shown is injection molded of a plastic material with the delegated 5 integrally molded with the side wall means.
