Den foreliggende opfindelse angår en emballagebeholder, navnlig til tørre, risledygtige produkter, og af den i indledningen til krav 1 angivne art.The present invention relates to a packaging container, particularly for dry, rice-resistant products, and of the kind specified in the preamble of claim 1.

Fra DE-B-12 79 533, DE-A-34 02 096, US-C-1 697 664, US-C-2 5 064 029 og US-C-3 185 374 kendes emballagebeholdere af denne art. Fælles for disse kendte emballagebeholdere er imidlertid, at de i deres udformning og med hensyn til deres lukning eller fiksering er indrettet til limning af top- og bundfladerne.Packaging containers of this kind are known from DE-B-12 79 533, DE-A-34 02 096, US-C-1 697 664, US-C-2 5 064 029 and US-C-3 185 374. However, what is common to these known packaging containers is that in their design and with regard to their closure or fixation, they are arranged for bonding the top and bottom surfaces.

For at opnå sikre limsamlinger kræves relative store materia-10 leoverlapninger, og følgelig er top- og bundflader ved disse kendte emballagebeholdere dobbeltvæggede. Derudover er opriv-ningen af beholderne samt udfoldning af udtømningstuden betinget af, at der i emballageemnerne er udformet perforeringer, langs med hvilke kartonmaterialet skal brydes. Sådanne perfo-15 reringer ødelægger imidlertid beholdermaterialets eventuelle barriereegenskaber, ligesom arbejdet med udstansning af emballageemnerne kompliceres væsentligt, idet der kræves ret hyppige stop for at kontrollere kvaliteten af perforeringerne.In order to obtain safe adhesive joints, relatively large material overlaps are required, and consequently the top and bottom surfaces of these known packaging containers are double-walled. In addition, the tearing up of the containers and unfolding of the discharge spout is conditional on perforations forming in the packaging blanks along which the cardboard material is to be broken. However, such perforations destroy the possible barrier properties of the container material, as well as the work of punching out the packaging items is considerably complicated, requiring fairly frequent stops to check the quality of the perforations.

Opfindelsen har til formål at angive en forbedret emballage-20 beholder af den indledningsvis angivne art, og ved hjælp af hvilken de forannævnte ulemper på enkel måde afhjælpes.It is an object of the invention to provide an improved packaging container of the kind initially indicated and by which the aforementioned disadvantages are easily remedied.

Emballagebeholderen ifølge opfindelsen er ejendommelig ved, at nævnte lågdel modsat den tværgående kant er udformet med en udragende tunge, der er indrettet til at udgøre et brydbart 25 segl for udtømningstuden i beholderens lukkede tilstand, og som desuden er indrettet til at udgøre et holdeorgan for udtømningstuden ved genlukning af denne, og ved at beholderen på hver side af den midterste lågdel har sidefløje, der er forbundet med modstående bredsider af beholderen, og som på i og 30 for sig kendt måde er indrettet til ved lukning af udtømningstuden at foldes sammen indad under lågdelen, der forløber skråt i forhold til en resterende plan topendedel, der er dannet af en foldbar endefløj samt dermed forbundne topendefløje,The packaging container according to the invention is characterized in that said lid portion is formed opposite the transverse edge with a protruding tongue arranged to constitute a breakable seal for the discharge nozzle in the closed state of the container and which is further adapted to constitute a holding means for the discharge nozzle. by re-closing it, and having the container on each side of the middle lid portion having side wings which are connected to opposite wide sides of the container and which in a known manner are adapted for folding inwardly by closing the discharge spout, the lid portion extending obliquely to a remaining planar top end formed by a foldable end wing and associated top end wing,

2 der er indrettet til indbyrdes at forbindes langs midten af nævnte plane topendedel, med hvilken tungen er brydbart forbundet. Herved opnås ved hjælp af enkle foranstaltninger en forbedret emballagebeholder, der ikke er behæftet med de om-5 talte ulemper ved kendte emballagebeholdere af denne type, idet åbning og udfoldning af udtømningstuden ikke samtidigt indebærer oprivning af perforeringer som det er tilfældet ved nogle af de omtalte kendte emballagebeholdere. I praksis medfører anvendelse af oprivningsperforeringer - udover som 10 nævnt at ødelægge emballagens tæthed - ofte også direkte ødelæggelse af emballagens genlukningsfunktion ved, at der ved opbrydning af perforeringer er stor risiko for utilsigtet itu-rivning af topendedelen af beholderen. Også fremstillingsmæssigt medfører det en væsentlig forenkling at kunne undvære 15 perforeringer, der ved udstansning af kartonemnerne relativt ofte skal efterkontrolleres. Som angivet nedenfor kan emballagebeholderen ifølge opfindelsen fortrinsvis være indrettet med henblik ρ-å indbyrdes fiksering af de respektive fløj dele ved ultralydsvejsning, der til forskel fra de nævnte kendte embal-20 lager kun kræver ganske beskeden overlapning af kartonmateriale. Dette medfører også en ret mærkbar besparelse, som typisk for en emballagebeholder med et rumindhold på 1,5 - 2,0 liter giver en materialebesparelse på 12 - 20%. Det må desuden anses som en betydelig forbedring, at genlukning af beholderens ud-25 tømningstud kan foregå på enkel måde, uden at kræve særlig instruktion .2 arranged to be mutually connected along the center of said plane top end with which the tongue is breakably connected. Hereby, by simple measures, an improved packaging container is not obtained, which does not suffer from the mentioned disadvantages of known packaging containers of this type, since opening and unfolding of the discharge spout does not simultaneously entail tearing up perforations as is the case with some of the aforementioned known packaging containers. In practice, the use of tear-off perforations - besides, as mentioned 10, to destroy the density of the packaging - often also leads to direct destruction of the re-closing function of the packaging by the fact that in breaking up perforations there is a great risk of unintentionally tearing the top part of the container. In terms of manufacturing, it also means a considerable simplification to be able to do away with 15 perforations which, when stamping out the carton blanks, relatively often have to be checked. As indicated below, the packaging container according to the invention may preferably be arranged for fixing the respective wing parts by ultrasonic welding, which, unlike the known packaging packages, requires only very small overlap of carton material. This also results in a quite noticeable saving, which typically for a packaging container with a capacity of 1.5 - 2.0 liters gives a material saving of 12 - 20%. In addition, it must be considered a significant improvement that the re-closure of the container discharge nozzle can be carried out in a simple manner, without requiring special instruction.

Med henblik på at opnå en mere præcis udtømning af indholdet af risledygtigt materiale via udtømningstuden er beholderen fortrinsvis udformet således, at den midterste lågdel af ud-30 tømningstuden er indrettet til at kunne udgøre en konkav tudbund ved hjælp af foldelinier, der fra hver sin side af den tværgående kant, der udgør et hængsel for udtømningtuden, forløber skråt opad til midt for en tværgående foldelinie mellem lågdelen og den udragende tunge, der ligeledes er udformet med 35 en foldelinie ud for midten af lågdelen.In order to obtain a more precise discharge of the content of rice-resistant material via the discharge spout, the container is preferably designed such that the middle lid portion of the discharge spout is arranged to be able to form a concave spout bottom by means of folding lines which on each side of the transverse edge forming a hinge for the discharge spout extends upwardly to the center of a transverse fold line between the lid portion and the protruding tongue also formed with a fold line beyond the center of the lid portion.

Emballagebeholderen ifølge opfindelsen kan være fremstillet af dobbeltsidigt formstofkacheret karton, idet den indbyrdes fiksering af kartonemnets respektive side- og/eller endedele er indrettet til at udføres ved varmesvejsning, fortrinsvis ul-5 tralydsvejsning, og med særlig fordel kan beholderen være udformet således, at udtømningstuden og den plane topendedel forud for fyldning af beholderen er foldet sammen og er fifcse-ret ved hjælp af svejsesømme langs modstående sider af lågdelen, langs den tværgående frie endekantdel af topendedelen 10 (brydbar fiksering af tungen), langs midten af den plane topendedel samt med en tværgående svejsesøm langs kortsidekanten modsat udtømningstuden.The packaging container according to the invention may be made of double-sided plastic cached cardboard, the mutual fixing of the respective side and / or end portions of the cardboard blank being arranged for heat welding, preferably ultrasonic welding, and with particular advantage the container may be designed so that the discharge spout and the flat top end prior to filling the container is folded and is flexed by welding seams along opposite sides of the lid portion, along the transverse free end edge portion of the top portion 10 (foldable tongue fixation), along the center of the flat top portion, and with a transverse weld seam along the short side edge opposite the discharge spout.

I forhold til de omtalte kendte emballagebeholdere af lignende art er det en meget betydelig fordel, at emballagebeholderen 15 ifølge opfindelsen er indrettet således, at svejsefikseringen af udtømningstuden er udført på sådan kontrolleret måde, at den tværgående svejsesøm i afstand fra den frie forkant af tungen samt svejsesømmene langs modstående sider af lågdelen nemt kan brydes ved træk i den frie kantdel af tungen samt ved 20 eventuelt samtidigt indadrette tryk på modstående bredsider af beholderens topendedel - umiddelbart under udtømningstuden.Compared to the known prior art packaging containers of a similar nature, it is a very significant advantage that the packaging container 15 according to the invention is arranged so that the welding fixation of the discharge spout is carried out in such a controlled manner that the transverse welding seam is at a distance from the free leading edge of the tongue and the weld seams along opposite sides of the lid part can easily be broken by pulling in the free edge part of the tongue and by possibly simultaneously pressing inwardly on opposite width sides of the top end of the container - immediately below the discharge spout.

The fold lines 4 divide the carton blank 2 into squares corresponding to the 25 respective side portions of a packaging container, so the individual squares are designated by the same reference numerals as the respective late mentioned portions. The cardboard blank 2 is made of double 5

DK 158146 BDK 158146 B

beltsidigt formstofkacheret karton. Kacheringen består af po-lyethylen eller et tilsvarende varmeforsegleligt formstof, i-det fiksering af det opfoldede beholderemne (fig. 2) foregår ved ultralydsvejsning på passende dorne. Kartonemnet 2 opfol-5 des først til et firkantrør jfr. fig. 2 ved foldning langs foldelinierne 4 mellem de respektive smal- og bredsider af beholderemnet. Derefter udføres en langsgående svejsesamling for fiksering af en smal forbindelsesdel 6 til en sidekantdel af en bredside 8. Det skal nævnes, at kartonemnet 2 i fig. 1 er 10 vist med ydersiden vendende opad fra papirets plan.belted plastic cached cardboard. The caching consists of polyethylene or a similar heat-sealable resin, in that fixation of the folded container blank (Fig. 2) takes place by ultrasonic welding on suitable mandrels. The cardboard blank 2 is first folded into a square tube, cf. FIG. 2 by folding along the fold lines 4 between the respective narrow and wide sides of the container blank. Then, a longitudinal weld joint is carried out for fixing a narrow connecting portion 6 to a side edge portion of a wide side 8. It should be noted that the carton blank 2 in FIG. 1, 10 is shown face up from the plane of the paper.

Derefter-lukkes en øvre endedel 10 af beholderemnet jfr. fig.An upper end portion 10 of the container blank is then closed, cf. FIG.

3-5, idet en plan topendedel 12 først lukkes ved indadføring af en trekantet endefløj 14, hvorved ligeledes trekantede mindre sidefløje 16 mellem endefløjen 14 og henholdsvis en 15 smal topendefløj 18 og en bredere topendefløj 20 samtidigt foldes ind under topsendefløjene 18 og 20, hvoraf sidstnævnte, dvs. den bredeste, ved en hjørnedel mod en af sidefløjene 16 er skråt afskåret, således at den brede topendefløj 20 kan føres ind under den smallere topendefløj 18, idet nævnte skrå 20 afskæring muliggør indføring, uden at den modstående sidefløjdel 16, der jo er foldet ind under topendefløjen 18, kommer i vejen for indføringen af den brede topendefløj 20 under den smalle topendefløj 18. Den plane topendedel 12 fikseres derefter ved ultralydsvejsning på en passende dorn.3-5, wherein a flat top end 12 is first closed by insertion of a triangular end wing 14, thereby also triangular smaller side wing 16 between the end wing 14 and a 15 narrow top end wing 18 and a wider top end wing 20 simultaneously folded under the top end wings 18 and 20, of which the latter, i.e. the widest, at an angle portion to one of the side wings 16, is obliquely cut, so that the wide top end wing 20 can be inserted under the narrower top end wing 18, said bevel 20 cutting allows insertion without the opposite side wing part 16 folded in below the top end wing 18, gets in the way of introducing the wide top end wing 20 below the narrow top end wing 18. The flat top end 12 is then fixed by ultrasonic welding on a suitable mandrel.

25 Den resterende del af den øvre endedel 10 består af en udtømningstud 22, hvoraf en midterste lågdel 24 er forbundet med en smalside 26 langs en tværgående kant 28 foroven ved smalsiden 26, idet kanten 28 er repræsenteret af en foldelinie 30 mellem lågdelen 24 og smalsiden 26. Lågdelen 24 er ved hver sin side 30 forbundet med henholdsvis bredsiden 8 og en modstående bredside 32 ved hjælp af foldbare, trekantede sidefløje 34. Disse har form som ligebenede trekanter med topvikler ud for førnævnte tværgående kant 28, der danner en art hængsel mellem lågdelen 24 og smalsiden 26. Indadfoldning af sidefløjene 34 6The remaining portion of the upper end portion 10 consists of a discharge nozzle 22, of which a middle lid portion 24 is joined to a narrow side 26 along a transverse edge 28 at the top of the narrow side 26, the edge 28 being represented by a fold line 30 between the lid portion 24 and the narrow side. 26. The lid portion 24 is connected at each side 30 to the width side 8 and an opposite width side 32, respectively, by means of foldable triangular side wing 34. These are in the form of straight-legged triangles with top coils next to the aforesaid transverse edge 28, which forms a kind of hinge between cover portion 24 and narrow side 26. Inward folding of the side wings 34 6

foregår langs foldelinier 36, der forløber langs nævnte topviklers vinkelhalveringslinier til en modstående fri kantdel af sidefløjene 34, der således ved indadføring af lågdelen 24 kan foldes ind under denne (fig. 10). Modsat foldelinien 30 er 5 lågdelen 24 forsynet med en udragende tunge 38, der som vist i fig. 5 kan tjene som et brydbart segl, idet tungen 38 rager ind over en tværgående endekantdel af den plane topendedel 12, hvortil tungen 38 kan fikseres ved ultralydsvejsning langs en tværgående linie, der er placeret tæt opad en foldelinie 40 10 mellem lågdelen 24 og tungen 38, dvs. således, at man nemt kan få fat i den yderste kantdel af tungen 38 for brydning af den tværgående svejsesøm ved åbning af udtømningstuden 22 (fig.takes place along fold lines 36 extending along the angular half-lines of said top winder to an opposing free edge portion of the side wings 34, which can thus be folded underneath it by insertion of the lid portion (Fig. 10). Opposite the fold line 30, the lid portion 24 is provided with a protruding tongue 38 which, as shown in FIG. 5 can serve as a frangible seal, the tongue 38 protruding over a transverse end edge portion of the planar top end 12, to which the tongue 38 can be fixed by ultrasonic welding along a transverse line located close up a fold line 40 10 between the lid portion 24 and the tongue 38 , ie so that one can easily grasp the outer edge portion of the tongue 38 for breaking the transverse weld seam by opening the discharge spout 22 (FIG.

9). Ved lukning af den øvre endedel 10 af beholderen udføres desuden en ultralyssvejsning langs modstående sidekanter af 15 lågdelen 24, således at denne på brydbar måde svejses sammen med de sammenfoldede sidefløje 34.9). In addition, by closing the upper end portion 10 of the container, an ultrasonic welding is performed along opposite side edges of the lid portion 24 so that it is welded in a breakable manner with the folded side wings 34.

Når den øvre endedel 10 således er lukket og fikseret kan fyldning af emballagebeholderen foregå fra den åbne bundende 42 deraf. Efter fyldning af emballagebeholderen lukkes bunden-20 den 42 på kendt måde som vist i fig. 6-8, idet nedre kantdele 44 svejselukkes som vist i fig. 6. Derefter foldes kantdelene 44 nedad mod bundfladen, inden de over smalsiderne af beholderen udragende endedele foldes indad og presses opad og fikseres for dannelse af en nærmest konkav bundflade.Thus, when the upper end portion 10 is closed and fixed, filling of the packaging container may take place from the open bottom 42 thereof. After filling the packaging container, the bottom 20 is closed in known manner as shown in FIG. 6-8, welding lower edge portions 44 as shown in FIG. 6. Then edge portions 44 are folded downwardly toward the bottom surface before the end portions projecting over the narrow sides of the container are folded inwardly and pressed upwardly and fixed to form a nearly concave bottom surface.

25 Åbning af den forseglede emballagebeholder foregår som vist i fig. 9 og 10, idet tungen 38 først bøjes opad, således at det er nemt at få et godt tag i den med fingrene. Nu kan den tværgående svejsesøm relativt let brydes ved et opadrettet træk i tungen 38. Ved samtidigt at klemme indad på modstående bredsi-30 der 8 og 32 umiddelbart under den skrå udtømningstud 22 hjælper man med til også at bryde svejseforseglingerne langs modstående sidekanter af lågdelen 24 (fig. 10). Derefter kan udtømningstuden 22 åbnes helt og som vist i fig. 11 anvendes til udhældning af indholdet fra emballagebeholderen. I fig. 11 ses25 The sealed packaging container is opened as shown in FIG. 9 and 10, with the tongue 38 first bent upwards so that it is easy to get a good grip on it with the fingers. Now the transverse weld seam can be relatively easily broken by an upward pull in the tongue 38. At the same time, squeezing inwards on opposite widths 8 and 32 immediately below the inclined discharge nozzle 22 also helps to break the weld seals along opposite side edges of the lid part 24 (Fig. 10). Then, the discharge spout 22 can be fully opened and as shown in FIG. 11 is used for pouring the contents from the packaging container. In FIG. 11 ses

DK 158146 BDK 158146 B

7 tydeligt, at lågdelen 24 af udtømningstuden 22 ved hjælp af foldelinier 46 og en central knæklinie 48 kan udgøre en konkav tudbund, der gør det lettere at kontrollere udtømning af beholderens indhold. Udtømningstuden 22 kan genlukkes ved indad-5 svingning af lågdelen 24, og ved indføring af tungen 38 under den frie tværgående endekant af den plane topendedel 12 kan udtømningstuden 22 på enkel og næsten tæt måde genlukkes og fikseres (fig. 12).7 clearly shows that the lid portion 24 of the discharge spout 22, by means of fold lines 46 and a central crack line 48, can constitute a concave spout bottom which makes it easier to control the discharge of the contents of the container. The discharge nozzle 22 can be resealed by inwardly swinging the lid portion 24, and by inserting the tongue 38 below the free transverse end edge of the planar top end 12, the discharge nozzle 22 can be resealed and fixed in a simple and almost dense manner (Fig. 12).

I fig. 12 er vist, hvordan udtømningstuden 22 kan genlukkes 10 ved, at lågdelen 24 svinges ind mod den skrå endedel og låsetungen 38 indføres under den fri forkant af den plane topende 12. I fig. 13 er vist en foretrukken form for et kartonemne 52, hvor den brede topendefløj 20 er placeret i modsatte side set i forhold til det i fig. 1 viste kartonemne. Herved er det 15 som vist muligt at spare kartonmateriale, fordi den brede topendefløj 20 er placeret i den side af kartonemnet 52, hvor også udtømningstuden 22 findes, således at man ved udstansning af kartonemner 52 kan forskyde disse indbyrdes i omvendt stilling, hvorved der bliver et minimalt spild af kartonmateriale, 20 især når der anvendes et udgangsmateriale med en bredde svarende til højden af to således sammenlagte kartonemner 52. Herved understreges i øvrigt nogle fordele ved den skrå udtømningstud 22, der for det første giver materialebesparelse, og som for det andet betyder en større og bedre markeret udtøm-25 ningstud 22. Især sidstnævnte fordel anses for vigtigt ved opfindelsen, idet det set fra forbrugerens synspunkt er af stor betydning at have en tydeligt markeret og stor udtømningsåbning .In FIG. 12, it is shown how the discharge nozzle 22 can be resealed 10 by pivoting the lid portion 24 towards the inclined end portion and the locking tongue 38 being inserted below the free leading edge of the plane top end 12. In FIG. 13 is a preferred form of a cardboard blank 52 where the wide top end wing 20 is positioned on the opposite side as compared to that of FIG. 1 carton blank. Hereby, it is possible to save cardboard material 15 as shown, because the wide top end wing 20 is located on the side of the carton blank 52, where also the discharge nozzle 22 is located, so that when punching carton blank 52 it can be displaced in reverse position thereby a minimal waste of cardboard material, 20 especially when using a starting material of a width corresponding to the height of two thus-carton blanks 52. This further emphasizes some advantages of the oblique discharge nozzle 22, which firstly provides material savings and which, secondly, means a larger and better marked discharge stud 22. In particular, the latter advantage is considered important in the invention, since from the consumer's point of view it is of great importance to have a clearly marked and large discharge opening.

En særlig foretrukken form for låsetungen 38 er vist i fig.A particularly preferred form of the locking tongue 38 is shown in FIG.

30 14, hvor låsetungen 38 ved basis, dvs ud for foldelinien mellem låsetungen 38 og lågdelen 24, har indadbuede indhak 54 nedenfor skrå sidekanter 56 af låsetungen 38. Indhakkene 54 er beregnet til at samvirke med modstående hjørneområder 58 ved den frie tværgående endekant af den plane topendedel 12, dvs.30 14, wherein the locking tongue 38 at the base, i.e., outside the fold line between the locking tongue 38 and the lid part 24, has inwardly curved notches 54 below inclined side edges 56 of the locking tongue 38. The notches 54 are intended to cooperate with opposite corner regions 58 at the free transverse end edge of the plane top part 12, i.e.

88

DK 158146 BDK 158146 B

at længden af den frie tværgående endekant er lidt mindre end bredden af udtømningstuden 22 og låsetungen 38.that the length of the free transverse end edge is slightly smaller than the width of the discharge spout 22 and the locking tongue 38.

Afslutningsvis skal nævnes, at emballagebeholderen ifølge opfindelsen giver mulighed for en kompakt fyldning af emballa-5 gen, således at der over det ifyldte produkt - det være sig et tørt, risledygtigt produkt, et pastaformigt produkt eller et flydende produkt - ikke forekommer et skadeligt luftrum, der kan have uheldig indvirkning på holdbarheden af et eventuelt produkt med begrænset holdbarhed.Finally, it should be mentioned that the packaging container according to the invention allows for a compact filling of the packaging, so that no harmful air space is present over the filled product - be it a dry, rice-containing product, a pasty product or a liquid product. that may adversely affect the shelf life of any product with limited shelf life.
