Opfindelsen angår en samleemballage af den art, der er angivet i indledningen til krav 1.The invention relates to an assembly package of the kind specified in the preamble of claim 1.

Emballager af denne art er ofte helt lukkede, så at de emballerede genstande ikke kan ses uden at åbne embal-5 lagen, eller også er forsynet med åbninger, hvorigennem i det mindste dele af genstandene kan ses udefra. Der kendes også samleemballager bestående af en bæreplade med til genstandene svarende fordybninger og forhøjninger, mod hvilke genstandene fastholdes ved hjælp af en gennemsigtig omslut-10 ningsfolie. Ganske vist stilles herved genstanden alsidigt til skue, men disse emballager er ikke altid velegnet til emballering af genstande, der har en pladskrævende yderform. Endvidere er sådanne omslutningsfolier ofte ikke nedbrydelige på samme måde som f iberpulpmateriale, der som bekendt normalt 15 består af papiraffald og ved sin fremstilling løser i det mindste en del af problemerne med bortskaffelse af sådant affald.Packages of this kind are often completely closed so that the packaged items cannot be seen without opening the packing layer, or are provided with openings through which at least parts of the objects can be viewed from the outside. Also known are assembly packages consisting of a carrier plate with recesses and projections corresponding to the articles against which the articles are held by means of a transparent wrapping film. Of course, the object is thus versatile, but these packages are not always suitable for packaging objects that have a space-consuming outer shape. Furthermore, such wrap foils are often not degradable in the same way as fiber pulp material, which, as is well known, normally consists of paper waste and in its manufacture solves at least some of the problems of disposal of such waste.

Formålet med opfindelsen er at anvise udformningen af en samleemballage af den indledningsvis nævnte art, der 20 ikke er behæftet med de omtalte ulemper, og dette opnås ved en sådan emballage, som ifølge opfindelsen tillige udviser de træk, der er angivet i den kendetegnende del af krav 1.The object of the invention is to provide the design of an assembly package of the type mentioned in the beginning, which does not suffer from the mentioned disadvantages, and this is achieved by such packaging which according to the invention also exhibits the features indicated in the characterizing part of the invention. claim 1.

Herved opnås, at også genstande med en pladskrævende yderform kan stilles til skue på en enkel måde, idet dele 25 af genstanden, hvis tværmål er forholdsvis mindre, kan rage frit frem, medens andre dele af genstanden, hvis tværmål er forholdsvis større, tjener til at fastholde genstanden til emballagen ved, at den går i indgreb med den nævnte frie åbning. Derudover muliggør den angivne udformning, at samle-30 emballagen kan fremstilles i ét arbejdstrin ved anvendelse af den for fremstillingen af genstande af fiberpulpmateriale karakteristiske sugeformteknik, ved hvilken et fiberpulplag ved påsugning aflej res på konturfladen af en sugeform, idet den frie åbning kan tilvejebringes ved, at en materialeaf-35 lejring ved det pågældende sted forhindres. I sammenligning hermed ville tilvejebringelsen af en sådan åbning normalt DK 171466 B1 2 kræve mere indviklede arbejdsoperationer, hvis emballagen skulle sprøjtestøbes eller vakuumstøbes af plast.Hereby it is achieved that even objects with a space-consuming outer shape can be seen in a simple way, since parts 25 of the object, whose cross dimensions are relatively smaller, can project freely, while other parts of the object, whose cross dimensions are relatively larger, serve to retaining the article to the packaging by engaging said free opening. In addition, the design disclosed allows the assembly package to be manufactured in one working step using the characteristic suction molding technique characteristic of the manufacture of articles of fiber pulp material, in which a fiber pulp coating is deposited on the contour surface by a suction mold, the free opening being provided by that a material deposit at that site is prevented. In comparison, the provision of such an opening would normally require more complicated work operations if the packaging were to be injection molded or vacuum molded of plastic.

Ved den i krav 2 angivne udførelsesform for samle-emballagen ifølge opfindelsen opnås, at emballagen ikke 5 alene vil kunne gives form af en bakke, men også eksempelvis kunne udformes som en genstand mere eller mindre omgivende emballage, i hvilken den nævnte bæreflade for genstanden kunne udgøre bunden for en skålformet emballage.In the embodiment of the assembly package according to the invention set out in claim 2, it is achieved that the package 5 can not only be given the shape of a tray, but also, for example, can be designed as an article more or less surrounding packaging in which said supporting surface of the article could form the bottom of a bowl-shaped package.

Ved den i krav 3 angivne udførelsesform opnås, at 10 den til fastholdelse af genstanden til emballagen tjenende næse får en skrå påløbsflade, der letter genstandens forankring til emballagen. Også denne udformning kan fremstilles i ét arbejdstrin sammen med den øvrige formgivning af emballagen. Der vil også kunne anvendes flere næser, placeret i 15 hver sin højde.In the embodiment according to claim 3, it is achieved that the nose serving to hold the article to the packaging is provided with an inclined mounting surface which facilitates the anchoring of the article to the packaging. This design can also be manufactured in one working step together with the other design of the packaging. Several noses can also be used, placed at 15 different heights.

Ved den i krav 4 angivne udførelsesform muliggøres en særlig god forankring til emballagen af genstandens anden bestanddel samtidig med, at den samlede forankringsåbning kan frembringes særlig nemt ved sugestøbning.In the embodiment according to claim 4, a particularly good anchoring to the packaging of the second component of the article is possible, while the overall anchoring opening can be produced particularly easily by suction molding.

20 Opfindelsen skal i det følgende forklares nærmere under henvisning til tegningen, på hvilken fig. 1 viser set fra oven en skrå afbildning af en udførelsesform for en samleemballage ifølge opfindelsen, fig. 2 samme set nedefra, 25 fig. 3 et tværsnit efter linien III-III i fig. 1, og fig. 4 et tværsnit efter linien IV-IV i fig. 1. Tegningen viser en samleemballage, der skal fremstilles ved påsugning af et fiberpulpmateriale på en sugeform, der har en konturgivende yderflade. Efter fremstillingen på 30 sugeformen underkastes emnet en tørringsproces, om ønsket efterfulgt af en formstabiliserende efterpresningsoperation.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail with reference to the drawing, in which 1 is a top plan view of an embodiment of an assembly package according to the invention; FIG. 2 is a bottom view, FIG. 3 is a cross-sectional view taken along line III-III of FIG. 1, and FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 1. The drawing shows an assembly package to be manufactured by aspirating a fiber pulp material onto a suction mold having a contour-giving outer surface. After preparation of the suction mold, the blank is subjected to a drying process, if desired, followed by a mold stabilizing post-pressing operation.

I det viste eksempel har samleemballagen 10 form af en aflang skål, der i bunden er udformet med fordybninger, f.eks. 12, og i sidevæggen har indvendige forhøjninger, 35 f.eks. 14, alt svarende til formen af én eller flere, ikke viste genstande, der skal emballeres. Fordybningerne 12 er DK 171466 B1 3 udformet i en bæreflade 16 for genstanden eller genstande. Forhøjningerne 14 har form af en næse med opefter aftagende tværsnitsform.In the example shown, the assembly package 10 is in the form of an elongated bowl formed at the bottom with recesses, e.g. 12, and in the side wall have internal elevations, e.g. 14, all corresponding to the shape of one or more items not shown to be packaged. The recesses 12 are formed in a support surface 16 for the object or objects. The elevations 14 take the form of a nose with decreasing cross-sectional shape.

Forhøjningerne 14 udgør en første del af emballagen, 5 og danner del af en åbning. Denne er dimensioneret til, at en bestanddel af en genstand, som har mindre tværmål end mindst én anden bestanddel af genstanden, kan rage frem igennem åbningen. Disse bestanddele er med stiplede linier eksemplificeret i fig. 3, idet den nævnte første bestanddel 10 er betegnet med 18, og den nævnte anden bestanddel er betegnet med 20. Til emballagen ifølge opfindelsen hører også en bæreflade, der danner bunden i fordybningen 12. Bærefladen kan udgøres af selve fordybningen 12's bund, jfr. fig. 2 til venstre, og fig. 4, men den kan også være dannet af en 15 fra bunden indvendig opragende, podiumdannende del 22, jfr. fig. 1 til højre, og fig. 3. Som nærmere vist i fig. 3 ligger delen 22 i et niveau neden under niveauet for forhøjningerne 14's nederste, brede ende med en afstand svarende til tykkelsen af genstandens bestanddel 20. Bestanddelen 20 har, 20 målt i sit niveau et større yderendemål, der i tværretning strækker sig udefter forbi bestanddelen 18, således at bestanddelen 20 kan gribe ind under forhøjningen 14's nederste endekant.The elevations 14 form a first part of the package, 5 and form part of an opening. This is designed so that a component of an object having a smaller cross-dimension than at least one other component of the object can project through the opening. These components are illustrated in dotted lines in FIG. 3, said first component 10 being designated 18 and said second component being 20. The packaging according to the invention also includes a carrier which forms the bottom of the recess 12. The carrier surface can be constituted by the bottom of the recess 12, cf. FIG. 2 to the left, and fig. 4, but it may also be formed by a bottom-up, podium-forming portion 22, cf. FIG. 1 to the right, and fig. 3. As illustrated in FIG. 3, the portion 22 lies at a level below the level of the lower, wide end of the elevations 14 at a distance corresponding to the thickness of the component component 20. The component 20, measured in its plane, has a larger outer end dimension extending transversely beyond the component 18. so that the component 20 can engage below the lower end edge of the elevation 14.

Til muliggørelse af et sådant indgreb begrænser for-25 bøjningen 14 med sin nederste endekant en fri åbning 24, der desuden er begrænset af rande fra udskæringer både i sidevæggen 26 af emballagesiden 28's fordybede ende, og af rande af en åbning 30, der er udformet i fordybningerne 12's bund, jfr. til venstre i fig. 2 og fig. 4, eller i en med 30 U-formet tværsnit udformet standringdel, der omgiver den podiumdannende del 22, jfr. til højre i fig. 1 og 2, og fig. 3.To enable such an engagement, the bend 14, with its lower end edge, limits a free opening 24, which is further limited by edges from cutouts both in the side wall 26 of the recessed end of the packaging side 28 and by the edges of an opening 30 which is formed. in the bottom of the recesses 12, cf. to the left of FIG. 2 and FIG. 4, or in a stand portion formed with a 30 U-shaped cross-section surrounding the podium forming portion 22, cf. to the right in FIG. 1 and 2, and FIG. Third

Ved sugestøbning af emballagen på en sugeform kan hele åbningen i en enkelt påsugningsoperation tilvejebringes 35 ved, at sugeformens sugeflade blokeres på det tilsvarende formareal.By suction molding the package on a suction mold, the entire opening in a single suction operation can be provided by blocking the suction surface of the suction mold on the corresponding mold area.

Den næsedannende forhøjning 14 har et opefter aftagende tværsnit. Dette medfører, at den vender sin brede ende mod åbningen 24 og derved har en langstrakt anlægskant til fastholdelse af randen af genstandens bestanddel 20, 5 samtidig med, at den med sin yderryg danner en påløbsflade, som letter genstandens indføring i emballagen til det i fig. 3 illustrerede snapforbindelsesindgreb med genstandens bestanddel 20.The nose-forming elevation 14 has an upwardly decreasing cross-section. This causes it to face its wide end toward the opening 24 and thereby has an elongated abutment edge for retaining the rim of the component 20, 5 while at the same time forming with its outer back an opening surface which facilitates the insertion of the object into the package of the . 3 illustrates snap connection engagement with the component 20 of the object.

I den viste udførelsesform har emballagen en skålfor-10 met beholderdel 32, som de ovenfor omtalte emballageelementer er bestanddele af. Opfindelsen er imidlertid ikke begrænset til en beholderdel med viste høje sidevægge 28, idet disse også kan være forholdsvis mindre høje, eller kan have varierende højder.In the illustrated embodiment, the packaging has a bowl-shaped container portion 32 of which the above-mentioned packaging elements are constituents. However, the invention is not limited to a container portion with high sidewalls 28 shown, which may also be relatively less tall or may have varying heights.

15 I den viste udførelsesform er sidevæggen ydermere udstyret med en sideåbning 34, igennem hvilken en sideværts udragende del af den emballerede genstand kan passere.Further, in the embodiment shown, the side wall is provided with a side opening 34 through which a laterally extending portion of the packaged article can pass.

Bærefladen 16 har langs fladens underside forløbende fremspringende ribber 38 med et fordybet, rendeformet tvær-20 snit, som stedvis er udfyldt af tværgående, sammen med bære-fladen 16 udformede massive fremspring 36. Ribberne 38 og fremspringene 36 medstøbes sammen med den øvrige del af emballagen og kan tjene som afstandsribber imellem et antal emballager, som i tom tilstand stables ind i hinanden til 25 dannelse af en stak.The supporting surface 16 has projecting ribs 38 extending along the underside of the surface with a grooved, transverse cross-section, which is filled in transversely, formed together with the supporting surface 16, massive projections 36. The ribs 38 and the projections 36 are molded together with the other part of the the package and can serve as spacers between a plurality of packages which are stacked in an empty state to form a stack.
