Opfindelsen angår en fremgangsmåde til forebyggelse af revnedannelse i et emballeret, pladeformet krystallinsk produkt, især smør eller margarine, hvor den anvendte emballage forud for en foldning omkring produktet fremtræder arkformet, og hvor emballagen efter foldning 5 omkring produktet har et kantområde, der ligger an mod en flade af produktet.The invention relates to a method for preventing cracking in a packaged, plate-shaped crystalline product, in particular butter or margarine, where the packaging used prior to folding around the product appears sheet-shaped, and the packaging after folding around the product has an edge area which abuts against a surface of the product.
Gennem de senere år er det blevet mere almindeligt at fremstille smør og margarineprodukter i pladeform fremfor den konventionelle 10 blokform. Dette pladeformede produkt finder især anvendelse i industriel sammenhæng som f.eks. i bagerier. Ved anvendelse af sådanne plader lettes bageri arbejdet væsentligt. Til emballering af et sådant pladeformet produkt anvendes sædvanligvis en arkformet emballage, f.eks. en papiremballage.In recent years, it has become more common to produce butter and margarine products in plate form over the conventional 10 block form. This plate-shaped product is particularly applicable in an industrial context, e.g. in bakeries. By using such plates, bakery work is greatly facilitated. For packaging such a plate-shaped product, a sheet-shaped package is usually used, e.g. a paper packaging.

Imidlertid har det vist sig, at det emballerede, pladeformede smørener margarineprodukt ofte udviser tværgående revnedannelser, der bevirker, at produktet svækkes, således at det ved udpakning vil deles ved revnen. Som følge heraf må produktet kasseres, da eksem-20 pelvis dej, der er fremstillet ved anvendelse af sådanne brudte plader, udviser inhomogeniteter, hvilket er uønskeligt af hensyn til det færdige produkts fremtræden.However, it has been found that the packaged, plate-shaped lubricant margarine product often exhibits transverse cracking which causes the product to weaken so that when unpacked it will be split by the crack. As a result, the product must be discarded since, for example, dough made using such broken sheets exhibits inhomogeneities which is undesirable for the appearance of the finished product.
Revnedannelsen er forårsaget af, at der ved eksempelvis smør -eller 25 margarineproduktets modning eller færdigkrystallisering opstår trykspændinger i produktets indre og trækspændinger i produktets overflade. Ved en sædvanlig indpakning af et sådant produkt anvendes som nævnt ovenfor et folieark af papir eller lignende, som foldes omkring produktet, således at endekanterne af papiret overlapper 30 hinanden, hvorefter sidekanterne af papiret foldes. Ved sådanne kendte indpakninger er indpakningsfolien afskåret retlinet og dette kan som følge af, at den mod produktet vendende endekant forårsager en kærvdannelse, bevirke, at der opstår en revne langs denne endekant. Idet kanten af emballagen forårsager en kærvvirkning, bevirker 35 trækspændingerne i produktets overflade således så store spændingskoncentrationer i kantområdet, at en revne opstår.The cracking is caused by, for example, butter or margarine product maturation or final crystallization, compressive stresses in the product's interior and tensile stresses in the product's surface. In the usual wrapping of such a product, as mentioned above, a sheet of paper or the like is used which folds around the product so that the end edges of the paper overlap, and then the side edges of the paper are folded. In such known wrappers, the wrapping foil is cut off rectilinearly, and this may cause a crack along this end edge due to the end edge facing the product. Thus, since the edge of the packaging causes a notch effect, the tensile stresses in the surface of the product cause such high stress concentrations in the edge region that a crack occurs.
Et eksempel på tildannelse og emballering af et sådant pladeformet produkt er vist i EP-patent nr. 542886.An example of forming and packaging such a plate-shaped product is shown in European Patent No. 542886.

Formålet med opfindelsen er derfor at angive en fremgangsmåde til dannelse af et emballeret produkt af den indledningsvis angivne art, hvori der ikke dannes revner.The object of the invention is therefore to provide a method for forming a packaged product of the type initially stated in which no cracks are formed.
5 Dette opnås ved en fremgangsmåde, der er karakteristisk ved det i krav l's kendetegnende del angivne.This is achieved by a method characteristic of the characterizing part of claim 1.
Hensigtsmæssigt praktiseres en sådan fremgangsmåde ved, at der ved emballagekantens anlægsområde tilvejebringes et spor i produktet, 10 hvilket spor eksempelvis kan have sinusform eller del cirkel form i tværsnit.Conveniently such a method is practiced by providing a groove in the product area of the packaging edge, which groove may have, for example, sinusoidal or partial circular shape in cross section.
Ligeledes hensigtsmæssigt er det muligt at emballagekanten, som ligger an mod produktfladen, tildannes med en fra retlinet afvigende 15 form. Der kan eksempelvis være tale om bølgeform, takform, eller med indbyrdes afstand anbragte, i hovedsagen rektangulære tunger, henholdsvis tunger kun adskilt ved en indskæring i emballagens kantområde.Also conveniently, it is possible that the packaging edge abutting the product surface is formed in a shape which differs from the rectilinear. This may, for example, be a waveform, a roof shape, or spaced apart, generally rectangular tongues or tongues only separated by a cut in the edge area of the package.
20 Opfindelsen angår desuden en fremgangsmåde til dannelse af et spor i et emballeret, pladeformet krystallinsk produkt, især smør eller margarine, hvor den anvendte emballage forud for en foldning omkring produktet fremtræder arkformet, og hvor emballagen efter foldning omkring produktet har et kantområde, der ligger an mod en flade af 25 produktet, samt et ekstruderingsudstyr til brug ved denne fremgangsmåde.The invention further relates to a method of forming a groove in a packaged, plate-shaped crystalline product, in particular butter or margarine, where the packaging used prior to folding around the product appears sheet-shaped, and the packaging after folding around the product has an edge area lying against a surface of the product, as well as an extrusion equipment for use in this method.
Fremgangsmåden er karakteristisk ved, at der i ekstruderingsmund-stykket anbringes et legeme med tværsnitsform, svarende til den 30 ønskede tværsnitsform af sporet. Ekstruderingsudstyret er karakteristisk ved, at der i et dertil hørende ekstruderingsmundstykke findes et på tværs af ekstruderingsretningen udragende legeme med en tværsnitsform svarende til den ønskede tværsnitsform af sporet i produktet.The method is characterized in that a body having a cross-sectional shape corresponding to the desired cross-sectional shape of the groove is placed in the extrusion mouthpiece. The extrusion equipment is characterized in that in a corresponding extrusion nozzle there is a body extending transversely of the extrusion direction with a cross-sectional shape corresponding to the desired cross-sectional shape of the groove in the product.

Endelig angår opfindelsen en emballage til brug for emballering af et krystallinsk produkt, især smør eller margarine, hvor den anvendte emballage forud for en foldning omkring produktet fremtræder arkformet, og hvor emballagen efter foldning omkring produktet har 3 DK 171413 B1 et kantområde, der ligger an mod en flade af produktet.Finally, the invention relates to a package for use in the packaging of a crystalline product, in particular butter or margarine, where the packaging used prior to folding around the product appears sheet-shaped, and the packaging after folding around the product has an edge area adjacent to it. against a surface of the product.
En sådan emballage er karakteristisk ved at den i kantområdet er tildannet med en bølgeform, takform eller med tunger i indbyrdes 5 afstand, kun adskilt ved indskæringer.Such packaging is characterized in that in the edge region it is formed with a waveform, roof shape or with tongues at a distance of 5, separated only by cuts.
Foretrukne udførelsesformer for opfindelsen forklares i det følgende med henvisning til tegningen, hvor 10 fig. 1-4 viser et emballeret produkt, hvor emballagen har en fra en retlinet form afvigende kantudformning og fig. 5 viser et emballeret produkt med et spor dannet langs den mod produktet vendende emballagekant.Preferred embodiments of the invention will now be described with reference to the accompanying drawings in which: FIG. 1-4 shows a packaged product, the packaging having a rectangular shape which differs from a rectilinear shape and FIG. 5 shows a packaged product with a groove formed along the packaging edge facing the product.

Af figurerne 1-5 fremgår emballerede pladeformede krystallinske produkter 1, eksempelvis smør- eller margarineprodukter. Et sådant pladeformet produkt 1 har sædvanligvis en tykkelse, der er under 60 mm. Typisk ligger tykkelsen dog mellem 5 og 45 mm. Produktet er 20 emballeret i et arkformet materiale, eksempelvis af papir, som er foldet omkring produktet, således at en første endekant 2 af det arkformede materiale ligger an mod en flade af produktet, mens en anden endekant 3 af det arkformede materiale, modstående den første endekant 2, overlapper den første endekant. Den første og den anden 25 endekant af emballagen strækker sig på tværs af produktet i hele dets bredde, og har herved et meget større tværmål end bredden af produktet for at muliggøre en foldning ved sidekanterne. Denne foldning er i denne forbindelse ikke vist nærmere, da opfindelsen ikke er afhængig heraf. Et eksempel på en maskine til emballering er 30 f.eks. vist i EP 542 886. Bredden af et pladeformede produkt er sædvanligvis over 100 mm. Typisk er bredden dog mellem 150 og 500 mm. Det har vist sig, at den førnævnte tykkelse af produktet på under 60 mm sammen med bredden på over 100 mm udgør et kritisk mål for revnedannelse i produktet som følge af de i produktet under 35 færdigkrystalliseringen eller modningen opstående spændinger, der ved den af emballagekanten 2 forårsagede kærvvirkning når størrelser, der overstiger produktets brudstyrke.Figures 1-5 show packaged plate-shaped crystalline products 1, for example butter or margarine products. Such a plate-shaped product 1 usually has a thickness less than 60 mm. Typically, however, the thickness is between 5 and 45 mm. The product is packaged in a sheet-shaped material, for example, of paper, which is wrapped around the product such that a first end edge 2 of the sheet-shaped material abuts against a surface of the product, while a second end edge 3 of the sheet-shaped material, opposite the first end edge 2, the first end edge overlaps. The first and second 25 end edges of the package extend across the product throughout its width, thereby having a much larger cross-sectional dimension than the width of the product to allow folding at the side edges. In this connection, this folding is not shown further, since the invention is not dependent on it. An example of a packaging machine is 30 e.g. shown in EP 542 886. The width of a plate-shaped product is usually over 100 mm. Typically, however, the width is between 150 and 500 mm. It has been found that the aforementioned thickness of the product of less than 60 mm together with the width of more than 100 mm constitutes a critical measure of cracking in the product due to the stresses arising in the product during the final crystallization or maturation which at the packaging edge 2 caused notching effect when sizes exceeding the breaking strength of the product.
For at forhindre brud i produktet er der ifølge opfindelsen i 4 DK 171413 B1 området, hvor emballagens første endekant 2 ligger an mod produktet, tilvejebragt midler, som hindrer opståen af overkritiske spændingskoncentrationer. Fig. 1-5 viser eksempler på sådanne midler.In order to prevent breakage of the product, according to the invention, in the area where the first end edge 2 of the packaging abuts against the product, means are provided which prevent the occurrence of supercritical stress concentrations. FIG. 1-5 show examples of such agents.
5 På fig. 1 ses et emballeret produkt 1, hvor emballagen er tildannet med bølgeform ved den mod produktet vendende første endekant 2. Fig.5 In FIG. 1 shows a packaged product 1 in which the package is formed in a waveform at the first end edge facing the product 2. FIG.
2 viser tilsvarende en emballage, hvor den første endekant 2 er tildannet med takker, der udviser i alt væsentligt trekantform.2, similarly, shows a package in which the first end edge 2 is formed with branches which exhibit a substantially triangular shape.
10 Af fig. 3 fremgår en emballage, hvor den første endekant 2 er udformet med i hovedsagen rektangulære tunger i indbyrdes afstand.10 From FIG. 3 shows a package in which the first end edge 2 is formed with substantially rectangular tongues at a distance from one another.
Som det fremgår af fig. 4, er det også muligt, at disse tunger udelukkende er adskilt ved en indskæring i emballagekanten.As shown in FIG. 4, it is also possible that these tongues are separated only by a cut in the packaging edge.
15 Afstanden mellem disse kantudformningers yderste områder af bølgetoppe, takspidser eller tunger og bundområderne er fortrinsvis mellem 5 og 30 mm, mens afstanden mellem toppene og spidserne, henholdsvis midten af de i hovedsagen rektangulære tunger fortrinsvis er 5-50 mm.The distance between the outermost regions of these edge shapes of corrugated peaks, roof tips or tongues and the bottom regions is preferably between 5 and 30 mm, while the distance between the peaks and the points, respectively, the center of the generally rectangular tongues is preferably 5-50 mm.

Af fig. 5 fremgår et emballeret produkt, hvor der ved emballagens første endekants 2 anlægsområde er udformet et spor 4 langs den første emballagekant 2 og i hele produktets bredde, således at emballagekanten 2 i dette område ikke er i direkte kontakt med 25 produktet.In FIG. 5 shows a packaged product, where at the abutment area 2 of the packaging, a groove 4 is formed along the first packaging edge 2 and throughout the width of the product, so that the packaging edge 2 in this area is not in direct contact with the product.
Sporet kan eksempelvis dannes ved, at der i et til et ekstruderings-udstyr hørende ekstruderingsmundstykke anbringes et på tværs af ekstruderingsretningen udragende legeme, eksempelvis en stang med en 30 tværsnitsform svarende til den ønskede tværsnitsform af sporet i produktet. Særlig hensigtsmæssigt er sporet sinusformet i tværsnit, men enhver tværsnitsform uden indadvendende skarpe hjørner vil have en mod revnedannelse forebyggende effekt. Det er derudover også muligt at danne sporet efter ekstrudering af produktet, idet dette 35 eksempelvis kan ske ved at føre produktet forbi et hjul anbragt efter ekstruderingsmundstykket, hvilket hjul danner det ønskede spor. Herved har hjulets kantområde et tværsnit svarende til det ønskede sportværsnit.The groove may be formed, for example, by placing in a extrusion nozzle belonging to an extrusion device a body extending transversely of the extrusion direction, for example a rod having a cross-sectional shape corresponding to the desired cross-sectional shape of the groove in the product. Particularly conveniently, the groove is sinusoidal in cross-section, but any cross-sectional shape without inwardly sharp corners will have a preventive effect against cracking. In addition, it is also possible to form the groove after extrusion of the product, as this can be done, for example, by passing the product past a wheel disposed after the extrusion nozzle, which wheel forms the desired groove. Hereby the rim area of the wheel has a cross-section corresponding to the desired cross-section of the sport.
