Abstract

A collapsible tray produced from a rigid blank. Two walls (6, 8) of the tray are each provided with a respective first fold line (18, 18) which extends parallel with the lower edge of the wall, and a respective second and a third fold line (20,21 and 22,23) which extends from a respective one of the two lower corners of the wall to a respective free edge (14,16) of the wall while intersecting the first fold line to form an oblique angle (v1) therewith, the second and the third fold lines forming an angle of about 45 DEG with a respective side edge extending from the same corner. The tray can be either folded along the first fold line to form rim sections (26-29) which when folded outwards lock the walls in a position in which folding along the second and the third fold lines is prevented, or can be folded along the second and the third fold line, so as to collapse the tray.

Den foreliggende opfindelse angår en sammenfoldelig højvægget beholder der er fremstillet af et plant, stift materialeemne med en firkantet bund, som er begrænset af fire bundkanter og med fire vægge, der hver fremviser dels en nedre kant, som er sammenfaldende med hver sin af 5 nævnte bundkanter, dels to sidekanter, der hver langs en forudbestemt strækning er sammenfaldende med en respektiv sidekant på den tilstødende væg og dels en øvre fri kant, hvor hver af to første mod hinanden modstående vægge af væggene fremviser en første bøjningslinie, der forløber mellem væggens to sidekanter og parallelt med væggens nedre 10 kant samt en anden og en tredje bøjningslinie, der udgår fra hver sin af væggens to nedre hjørner til væggens frie kant krydsende den første bøjningslinie under en skrå vinkel, hvorved den anden og tredje bøjningslinie danner en ca. 45° vinkel med den fra samme hjørne udgående sidekant, hvorved nævnte første vægge hver enten kan foldes langs den 15 første bøjningslinie under dannelse af en sarg, som i en udfoldet tilstand låser væggen i en stilling, hvor foldning langs den anden eller tredje bøjningslinie forhindres eller kan foldes langs den anden og tredje bøjningslinie, således at hver af de to første vægge kan foldes langs sin nedre kant udefter til de ligger i plan med beholderens bund, 20 og således at hver af de to andre vægge samtidig kan foldes langs sin nedre kant ind mod beholderens bund.The present invention relates to a foldable, high-walled container made of a flat, rigid material blank having a square bottom limited by four bottom edges and having four walls, each having a lower edge coinciding with each of the above-mentioned five. bottom edges, partly two side edges, each of which along a predetermined stretch coincide with a respective side edge of the adjacent wall, and partly an upper free edge, each of two first opposing walls of the walls showing a first bending line extending between the two walls of the wall. side edges and parallel to the lower edge of the wall as well as a second and a third bending line extending from each of the two lower corners of the wall to the free edge of the wall crossing the first bending line at an oblique angle, thereby forming the second and third bending lines. 45 ° angle with the side edge extending from the same corner, wherein said first walls can each be folded along the first bending line to form a frame which in a unfolded condition locks the wall in a position where folding along the second or third bending line is prevented. or can be folded along the second and third bending lines so that each of the first two walls can be folded along its lower edge outwards until they lie flush with the bottom of the container, 20 and so that each of the other two walls can simultaneously be folded along its lower edge toward the bottom of the container.

Sammenfoldelige højvæggede beholdere af den i indledningen angivne art kendes for eksempel gennem DE patentskrift nr. 1.199.178. Denne kendte 25 beholder har flere ulemper. Selvom den omfatter forstærkninger i form af sarge, har den for svage hjørner. Hjørnerne er desuden ikke tætte.Foldable high-walled containers of the kind specified in the introduction are known, for example, through DE patent specification 1,199,178. This known container has several drawbacks. Although it includes reinforcements in the form of sarge, it has too weak corners. Furthermore, the corners are not tight.

De kendte beholdere kan endvidere ikke stables ind i hinanden.Furthermore, the known containers cannot be stacked together.

Formålet med den foreliggende opfindelse er følgeligt at tilvejebringe 30 en sammenfoldelig højvægget beholder, der ikke udviser nogle af de ovennævnte ulemper.Accordingly, the object of the present invention is to provide a collapsible high-walled container which does not exhibit any of the above disadvantages.

Ifølge den foreliggende opfindelse er der tilvejebragt en beholder af den i indledningen angivne art, hvilken beholder er ejendommelig ved 35 at væggene ved hvert af beholderens hjørner er forbundet ved hjælp af et hjørneelement, der består af et par vinkel paneler, der er forbundet med hinanden via en midterbøjningslinie, og som har et par sidebøjningslinier, der forbinder de respektive vinkelpaneler med den tilstødende væg, hvor de to vi nkel panel er i hvert hjørneelement er bundetAccording to the present invention there is provided a container of the kind set forth in the preamble, which is characterized in that the walls at each of the corners of the container are connected by a corner element consisting of a pair of angular panels connected to each other. via a center bend line, and having a pair of side bending lines connecting the respective angular panels to the adjacent wall, where the two corner panels are in each corner element is bonded

sammen og holdes fast mod overfladen af en af de tilstødende vægge for således både at forstærke og tætne hjørnet, hvilke sidebøjningslinier danner en vinkel, der er en smule større end 90° i forhold til den nedre kant af den respektive væg, så at væggene hælder en smule udad 5 fra bunden.together and held against the surface of one of the adjacent walls so as to both reinforce and seal the corner, which side bending lines form an angle slightly greater than 90 ° with respect to the lower edge of the respective wall so that the walls are inclined slightly outward 5 from the bottom.

Beholderen ifølge den foreliggende opfindelse er forbedret i forhold til den kendte beholder, ved at den omfatter hjørneelementer, der forstærker den og som også gør den tæt, hvilket opnås ved at arrangere 10 hjørneelementerne som nærmere angivet ovenfor, hvor hvert hjørneelement har to vinkelpaneler, der er forbundet med hinanden og med hver sin væg. Yderligere forstærkning er opnået ved, at beholderens vægge er gjort konkave eller hælder en smule udad, så at beholderne kan stables ind i hinanden i oprejst stilling. Ved en sådan stabling vil 15 sargene støtte mod hinanden, så at beholderstablen er gjort meget stabil og modstandsdygtig overfor kræfter. Beholderne kan derfor også stables i en container, når de er sammenfoldede, fra hvilken container de kan fjernes enkeltvis, idet de samtidig oprejses ved passage gennem en spaltelignende åbning i containeren.The container of the present invention is improved over the known container in that it comprises corner elements which reinforce it and also close it, which is achieved by arranging the corner elements as specified above, with each corner element having two angular panels which are connected to each other and to each wall. Further reinforcement is achieved by making the walls of the container concave or slightly inclined outwards so that the containers can be stacked into each other in an upright position. In such a stacking, the 15 bars will support each other so that the container stack is made very stable and resistant to forces. Therefore, the containers can also be stacked in a container when folded, from which container they can be removed individually, at the same time being raised by passage through a slot-like opening in the container.

Opfindelsen vil herefter forklares nærmere under henvisning til den medfølgende tegning, der viser en foretrukket udførelsesform for en beholder ifølge opfindelsen, og hvor fig. 1 viser en beholder ifølge opfindelsen i rejst stilling, 25 fig. 2 et billede af beholderen ifølge fig. 1 i rejst stilling og med udfoldede sarge fig. 3 et billede af beholderen ifølge fig. 1 i sammenfoldet stilling fig. 4 et materialeemne til fremstilling af beholderen, 30 fig. 5 et billede af den måde, hvorpå et låg kan fastlåses på beholderen, og fig. 5 et billede af en holder for beholderne.The invention will then be explained in more detail with reference to the accompanying drawing, which shows a preferred embodiment of a container according to the invention, and in which fig. 1 shows a container according to the invention in the raised position; FIG. 2 is a view of the container of FIG. 1 in the raised position and with unfolded sarge fig. 3 is a view of the container of FIG. 1 in the folded position FIG. 4 shows a blank for manufacturing the container; FIG. 5 is a view of the manner in which a lid can be locked onto the container; and FIG. 5 is a view of a container for the containers.

Idet der henvises til fig. 1 ses, at beholderen består af en firkantet 35 fortrinsvis rektangulær bund 1, som er begrænset af fire bundkanter 2-5 og har fire vægge 6-9, der hver fremviser en nedre kant, som er sammenfaldende med hver sin af bundkanterne 2-5 samt to sidekanter 10 og 11, 11 og 12, 12 og 13 henholdsvis 13 og 10, der hver og en langs en forudbestemt strækning (ca. 70-90% af sidekantens længde regnet fraReferring to FIG. 1, it is seen that the container consists of a square 35, preferably rectangular bottom 1, which is limited by four bottom edges 2-5 and has four walls 6-9, each having a lower edge coinciding with each of the bottom edges 2-5. and two side edges 10 and 11, 11 and 12, 12 and 13 and 13 and 10 respectively, each one along a predetermined stretch (about 70-90% of the length of the side edge from

væggens nedre hjørne) er sammenfaldende med en tilstødende vægs respektive sidekant.the lower corner of the wall) coincides with the respective side edge of an adjacent wall.

De dele af sidekanterne 10-13, som ikke er sammenfaldende med hinanden, 5 udgøres af sidekanterne på udfoldelige sarge, der senere vil blive beskrevet nærmere.The parts of the side edges 10-13 which do not coincide with each other 5 are constituted by the side edges of foldable edges which will be described in more detail later.

Væggene 6-9 fremviser desuden en øvre fri kant 14-17.Walls 6-9 also show an upper free edge 14-17.

10 Væggene 6-9 er hver og en fremstillet i form af en parallel afstumpet trekant, hvor trekantens grundlinie udgøres af den frie kant 14,15,16 henholdsvis 17. Derved hælder beholderens vægge noget udefter, således at flere rejste beholdere kan stables i hinanden.The walls 6-9 are each made in the form of a parallel blunt triangle, the base line of the triangle being the free edge 14,15,16 and 17. Thereby, the walls of the container tilt slightly outwards, so that several raised containers can be stacked together .

15 De to modstående vægge 6 og 8 fremviser en første bøjningslinie 18 henholdsvis 19, der forløber mellem begge væggens sidekanter 10 og 11, henholdsvis 12 og 13 samt parallelt med væggens nedre kant 2 henholdsvis 4. En anden og trejde bøjningslinie 20 og 21 henholdsvis 22 og 23 udgår fra hver sit hjørne af væggenes 6 og 8 to nedre hjørner til væg- 20 gens frie kant 14 henholdsvis 16, idet de krydser den første bøjningslinie 18 henholdsvis 19 under en skrå vinkel Vj, som er ca. 45°, såfremt beholderens vægge ikke hælder, og som, således som den i fig. 1 viste udførelsesform med hældende vægge, overstiger 45° i forhold til væggenes hældningsgrad. Hver af bøjningslinierne 20-23 deles derved af 25 bøjningslinierne 18 og 19 i en første nedre del 20a, 21a, 22a henholdsvis 23a, som befinder sig under bøjningslinien 18 henholdsvis 19 og i en anden øvre del 20b, 21b, 22b henholdsvis 23b, som befinder sig over bøjningslinien 18 henholdsvis 19.The two opposing walls 6 and 8 show a first bending line 18 and 19, respectively, extending between both side edges 10 and 11, 12 and 13, respectively, and parallel to the lower edge 2 of the wall 4 and 4. A second and third bending lines 20 and 21, respectively 22 and 23 extend from each corner of the two lower corners of the walls 6 and 8 to the free edge 14 and 16 of the wall 20 respectively, crossing the first bending line 18 and 19, respectively, at an inclined angle V 45 ° if the walls of the container are not inclined and which, as in FIG. 1 with inclined walls exceeding 45 ° relative to the slope of the walls. Each of the bending lines 20-23 is then divided by the bending lines 18 and 19 into a first lower portion 20a, 21a, 22a and 23a, respectively, which is below the bending line 18 and 19, respectively, and in a second upper portion 20b, 21b, 22b and 23b, respectively, which are above the bending line 18 and 19, respectively.

30 Bøjningslinierne 20-23 danner hver en vinkel v2, som er ca. 45° med den fra samme hjørne udgående sidekant 10, 11, 12 henholdsvis 13, således at beholderens sammenfoldning, under visse forudsætninger, kan ske langs linierne 20-23, således som det fremgår mere detaljeret herefter.The bending lines 20-23 each form an angle v2 which is approx. 45 ° with the side edge extending from the same corner 10, 11, 12 and 13, respectively, so that, under certain conditions, the folding of the container can take place along lines 20-23, as will be seen in more detail hereinafter.

4 ges 6 og 8 bøjningslinier 18 henholdsvis 19.4 are given 6 and 8 bending lines 18 and 19 respectively.

Den i fig. 1 viste beholder kan sammenfoldes til den i fig. 3 viste form ved, at beholderens vægge 7 og 9 foldes ind mod beholderens midte, 5 hvorved væggene 6 og 8 foldes langs bøjningslinierne 20-23, således som vist i fig. 3.The FIG. 1 can be folded into the container shown in FIG. 3, by folding the walls 7 and 9 of the container towards the center of the container 5, whereby the walls 6 and 8 are folded along the bending lines 20-23, as shown in FIG. Third

Såfremt væggene i den i fig. 1 viste beholder i stedet foldes udefter langs bøjningslinierne 18, 19, 24 og 25 for dannelse af udefterfoldede 10 sidestykker i form af såkaldte sarge 26-29, således som vist i fig. 2, danner de ovenfor nævnte øvre dele 20b, 21b, 22b henholdsvis 23b af bøjningslinierne 20-23 en vinkel med de tilsvarende nedre dele 20a, 21a, 22a henholdsvis 23a, således at en foldning langs bøjningslinierne 20-23 forhindres, og således at den rejste beholder bibringes en 15 meget stabil og veldefineret form.If the walls of the one shown in FIG. 1 is instead folded outwardly along the bending lines 18, 19, 24 and 25 to form outwardly folded 10 side pieces in the form of so-called lattice 26-29, as shown in FIG. 2, the above-mentioned upper portions 20b, 21b, 22b and 23b, respectively, of the bending lines 20-23 form an angle with the corresponding lower portions 20a, 21a, 22a and 23a, respectively, such that a fold along the bending lines 20-23 is prevented and raised container is given a very stable and well-defined shape.

Fig. 4 viser et tilklippet, plant emne af plastbehandlet karton eller lignende, hvilket gennem foldning og sammenføjning kan antage det i fig. 1-3 viste beholder-udseende. Fra hvert af beholderens fire bund-20 hjørner udgår to ekstra bøjningslinier 30a-b, 31a-b, 32a-b henholdsvis 33a-b. Ved sammenføjning af beholderens hjørnepartier gås der frem på analog måde med alle fire hjørner, hvorfor det her er tilstrækkeligt at beskrive sammenføjning af for eksempel det nedre højre hjørneområde i fig. 4.FIG. 4 shows a cut, flat piece of plastic-treated cardboard or the like, which can, by folding and joining, assume the position shown in FIG. 1-3. From each of the four bottom-20 corners of the container, two additional bending lines 30a-b, 31a-b, 32a-b and 33a-b respectively emerge. By joining the corner portions of the container progress is made in an analogous manner with all four corners, so it is sufficient here to describe joining of, for example, the lower right corner area of FIG. 4th

Der foldes først langs linierne 11,31a og 31b, hvorefter området mellem linierne 11 og 31a samt 31a og 31b bringes til at overlappe dels hinanden og dels en del af området mellem linierne 31b og 21a. Linien 31a er i den i fig. 4 viste stilling beliggende midt mellem linierne 11 og 30 31b, således at disse derved er sammenfaldende med hinanden og tilsam men danner den sidekant 11, som er vist i fig. 1-3. Hjørneområdet fik-seres derefter i sin rejste stilling ved limning, nitning eller svejsning af beholderens plastbehandlede yderlag.The lines 11,31a and 31b are first folded, after which the area between lines 11 and 31a and 31a and 31b is made to overlap partly and part of the area between lines 31b and 21a. The line 31a is in the embodiment of FIG. 4 is positioned midway between the lines 11 and 31b so that they thereby coincide with each other and form together but form the side edge 11 shown in FIG. 1-3. The corner area is then fixed in its raised position by gluing, riveting, or welding the plastic-coated outer layer of the container.

35 Alternativt kan det trekantformede område mellem linierne 31a og 31b være fjernet, således at kun området mellem linierne 11 og 31a behøver at blive fikseret mod væggen 6.Alternatively, the triangular area between lines 31a and 31b may be removed so that only the area between lines 11 and 31a needs to be fixed to the wall 6.

Således som det tydeligst fremgår af fig. 4 er bøjningslinierne 24 ogAs can be seen most clearly in FIG. 4, the bending lines 24 and

5 25 brudte mellem to punkter 34 og 35 henholdsvis 36 og 37, som udgør de to endepunkter for et U-formet snit 38 henholdsvis 39, som strækker sig ind i den tilsvarende sarg 28 henholdsvis 29. Ved udfoldning af sargene 28 og 29 danner de to snit 38 og 39 hver sin låsetunge, såle-5 des som vist i fig. 2 og 5.5 25 are broken between two points 34 and 35 and 36 and 37 respectively, which constitute the two end points of a U-shaped section 38 and 39, respectively, which extend into the corresponding jar 28 and 29, respectively. two sections 38 and 39 each locking tongue, as shown in FIG. 2 and 5.

To langstrakte, smalle låsespalter i form af udsparinger 40 og 41 er anbragt i sargen 14 henholdsvis 16, hvorved spalternes ene længdekant fortrinsvis er sammenfaldende med bøjningslinien 18 henholdsvis 19.Two elongated, narrow locking slots in the form of recesses 40 and 41 are disposed in the groove 14 and 16, respectively, whereby one longitudinal edge of the slots preferably coincides with the bending line 18 and 19, respectively.

1010

De beskrevne låsetunger og låsespalter er beregnet til at fastholde et låg 42, således som illustreret mere detaljeret i fig. 5, hvor der er vist en beholder med en form, der er identisk med den i fig. 2 viste beholder. Låget 42, som består af et plastbehandlet, plant papemne 15 eller lignende, fremviser derfor to låseflige 43 og 44, der for eksempel er dannet ved udstansning i lågets kanter samt to åbninger 45 og 46, for eksempel i form af gennemstansninger, og som er beregnet til at gå i indgreb med beholderens låsetunger 38 og 39 samt låsespalterne 40 og 41. Åbningerne 45 og 46 består hensigtsmæssigt dels af et lang-20 strakt snit 45a henholdsvis 46a, der er beregnet til at modtage hver sin af beholderens låsetunger, dels af to vinkelret på det langstrakte snit orienterede kortere snit 45b, c henholdsvis 46b, c, hvorved der dannes to låseflige mellem snittene 45b og c henholdsvis mellem snittene 46b og c. Herved kan låget 42 anbringes imod beholderens sarge, 25 hvorefter låget med et let tryk kan bringes i et fast snapindgreb mod beholderen.The locking tongues and locking slots described are intended to hold a lid 42, as illustrated in more detail in FIG. 5, showing a container of a shape identical to that of FIG. 2. The lid 42, which consists of a plastic-treated, flat cardboard blank 15 or the like, therefore exhibits two locking tabs 43 and 44 formed, for example, by punching at the edges of the lid and two openings 45 and 46, for example in the form of punches, which are intended to engage the locking tongues 38 and 39 of the container as well as the locking slots 40 and 41. The apertures 45 and 46 are conveniently comprised of an elongated section 45a and 46a respectively intended to receive each of the container's locking tongues and partly of two perpendicular to the elongate section are oriented shorter sections 45b, c and 46b, c, respectively, thereby forming two locking tabs between sections 45b and c respectively between sections 46b and c. Hereby the lid 42 can be placed against the container sarge, after which the lid with a slight pressure can be brought into a fixed snap engagement against the container.

I fig. 6 vises en holder 47 for flere beholdere, hvor beholderne er nedpakket sammenfoldede i en stabel, hvorfra beholderne en efter en 30 kan udtages, hvorved beholderen tvinges til at rejse sig, samtidig med at den udtages fra holderen.In FIG. 6, a container 47 for several containers is shown, in which the containers are unpacked folded into a stack, from which the containers can be removed one by one, forcing the container to rise while being withdrawn from the holder.

Holderen 47 har en bundvæg 48 og fire lodrette vægge 49-52. Væggen 49 fremviser langs sin lodrette midterlinie en lige bred spalteåbning 53 35 med stort set samme bredde som afstanden mellem bøjningslinierne 18 og 19 for de to vægge 6 og 8. Beholderne er i sammenfoldet tilstand stablet ovenpå hinanden for dannelse af en stabel 54 med en af deres nedre kanter 3 og 5 for væggene 7 henholdsvis 9 orienteret parallelt med spalteåbningen 53.The holder 47 has a bottom wall 48 and four vertical walls 49-52. The wall 49 shows along its vertical center line an equally wide gap opening 53 35 of substantially the same width as the distance between the bending lines 18 and 19 for the two walls 6 and 8. The containers are stacked on top of each other in folded form to form a stack 54 with one of the their lower edges 3 and 5 for the walls 7 and 9, respectively, oriented parallel to the gap opening 53.

Ovenpå stablen 54 hviler løst en modholdsvægt i form af en rektangulær plade 55, for eksempel af metal eller plast. Pladen 55 har ved to modstillede kanter en rektangulær udsparing 56 henholdsvis 57, hvorved pladen får en H-form, hvis midterstykke 58 adskiller de nævnte udspa-5 ringer 56 og 57 fra hinanden. Pladen 55 er orienteret med sin ene udsparing, for eksempel udsparingen 56, vendt imod spalteåbningen 53. Således som vist i fig. 6 kan en gribende hånd eller tilsvarende gribe om den øverste beholders væg 7 og påbegynde en vandret udtrækning af beholderen gennem spalteåbningen 53. Eftersom beholderen i den sammen-10 foldede tilstand, således som den har i stablen, er for bred til passage gennem spalteåbningen 53, styrer dennes kanter beholderens vægge 6 og 8 op, således at beholderen kan passere gennem spalteåbningen.On top of the stack 54 loosely rests a counterweight in the form of a rectangular plate 55, for example of metal or plastic. The plate 55 has at two opposite edges a rectangular recess 56 and 57, respectively, thereby giving the plate an H-shape whose center piece 58 separates said recesses 56 and 57 from each other. The plate 55 is oriented with its one recess, for example the recess 56, facing the slot opening 53. As shown in FIG. 6, a gripping hand or the like can grip the wall 7 of the upper container and initiate a horizontal withdrawal of the container through the slot opening 53. Since the container in the folded state, as it has in the stack, is too wide for passage through the slot opening 53 , its edges guide the walls 6 and 8 of the container so that the container can pass through the slot opening.

Når udtrækningen af beholderen er påbegyndt vil bagkanten på modvægt-15 pladens midterstykke 58 samtidigt hænge fast i beholderens bageste væg 9 og tvinge denne til at rejse sig, hvilket yderligere hjælper med til at rejse beholderen ved dennes udtrækning fra holderen. Når beholderens frie kanter 14 og 16 rejser sig, løfter de samtidig modvægtspladen 55. Ved beholderens fortsatte udtrækning glider beholderen således 20 nedenunder pladen 55. Når beholderens bageste væg 9 har rejst sig, slipper midterstykket 58's indgreb med væggen 9, idet denne da kan glide under midterstykket 58. Væggen 9's frigørelse fra midterstykket 58 lettes ved, at væggen 9 har den foldelige sarg 29. Umiddelbart efter beholderen har forladt spalteåbningen 53, falder pladen 55 atter 25 ned på beholderstablen 54.When the pull-out of the container has begun, the trailing edge of the center piece 58 of the counterweight plate will simultaneously adhere to the rear wall 9 of the container and force it to rise, which further helps to raise the container upon its withdrawal from the holder. As the free edges 14 and 16 of the container rise, they simultaneously lift the counterweight plate 55. Thus, upon continuing the container, the container 20 slides beneath the plate 55. When the rear wall 9 of the container rises, the engagement of the center piece 58 with the wall 9 then slides below the center piece 58. The release of the wall 9 from the center piece 58 is facilitated by the wall 9 having the foldable rim 29. Immediately after the container has left the slot opening 53, the plate 55 again falls on the container stack 54.

Pladen 55 kan naturligvis have en anden form end den viste. Det er dog en betingelse, at den har mindst samme bredde som afstanden mellem de frie kanter 14 og 16 i beholderens sammenfoldede tilstand, således at 30 pladen kan løftes af disse kanter ved beholderens rejsning. Endvidere behøver fasthængningsorganet 57 ikke et være udformet som en udsparing, men kan alternativt udformes som mindst en fremskydende tunge eller lignende (ikke vist), der er i stand til at hænge fast i den bageste væg 9 ved beholderens udtrækning gennem åbningen 53. Valget af fast-35 hængningsorgan i pladen 5 afgøres af graden af tilgængeligt rum mellem beholderens frie kanter 15 og 17 i beholderens sammenfoldede tilstand.The plate 55 may, of course, be of a different shape from that shown. However, it is a condition that it has at least the same width as the distance between the free edges 14 and 16 in the folded state of the container, so that the plate can be lifted by these edges when the container is raised. Further, the clamping member 57 need not be formed as a recess, but may alternatively be formed as at least one protruding tongue or the like (not shown) capable of clinging to the rear wall 9 upon the container's extension through the opening 53. The choice of fastening means in the plate 5 is determined by the degree of available space between the free edges 15 and 17 of the container in the folded state of the container.

Det er naturligvis også muligt at udforme fasthængningsorganet som en eller flere i udsparingen 57 anbragte tunger eller lignende, der således fremspringer fra midterstykket 58's bagkant. FasthængningsorganetOf course, it is also possible to design the clamping member as one or more tongues or the like arranged in the recess 57, thus projecting from the trailing edge of the center piece 58.

7 kan endvidere udformes som en eller flere tunger, der er fremspringende fra pladen 55's underside. I dette tilfælde behøves der således ingen udsparing 57 i pladen.7 may further be formed as one or more tongues projecting from the underside of the plate 55. In this case, thus, no recess 57 in the plate is needed.

5 Ifølge en alternativ udførelsesform kan låget sættes fast mod beholderen ved hjælp af en svejsning eller lignende. I dette tilfælde kan beholderens låsetunger og låsespalter samt lågets låseflige og åbninger altså undværes.According to an alternative embodiment, the lid can be secured to the container by means of a weld or the like. In this case, the container locking tongues and locking slots as well as the locking tabs and openings of the lid can thus be avoided.
