Definitions

  • the invention relates to a cup-shaped container having a height and sustaining a top load of at least 50 N when compressing the container by 3 mm in height
  • the container comprises a cup-shaped box made of a thermoplast
  • the cup-shaped box comprises a bottom and a shell
  • the container further comprises a strip in the form of a banderole applied onto the outer face of the shell and enclosing at least a part of the outer face of the shell in a shape-fitting manner.
  • the invention further relates to a process for manufacturing said cup-shaped container.
  • Cup-shaped containers having a banderole comprising advertising messages and/or information are well known in the art and have been disclosed for example in DE 29 2006 012 940 U1 and FR 2 336 307 B1 .
  • Those cup-shaped containers having a banderole are used for example for packaging yoghurt, fruit drinks or other food.
  • Those containers consist of a cup made of a bottom web comprising a bottom and a shell. Said containers are usually closed by a lid film sealed to an upper rim of the cup-shaped container.
  • the bottom web is commonly made of polystyrene (PS). Said bottom web has usually a standard wall thickness of about 850 ⁇ m in order to sustain a certain top load required for stacking a number of those containers.
  • Common banderoles are made of paper and have usually a grammage of about 95 g/m 2 .
  • the known cup-shaped containers show a high carbon footprint due to a quite thick bottom web used for manufacturing cup-shaped boxes sustaining a certain top load.
  • a further objective of present invention is to provide a cup-shaped container at lower costs while keeping the mechanical properties.
  • a cup-shaped container having a height and sustaining a top load of at least 50 N when compressing the container by 3 mm in height
  • the container comprises a cup-shaped box made of a thermoplast
  • the cup-shaped box comprises a bottom and a shell
  • the container further comprises a strip in the form of a banderole applied onto the outer face of the shell and enclosing at least a part of the outer face of the shell in a shape-fitting manner
  • the box is made of a bottom web having a film thickness of 600 ⁇ m or less and the banderole has a grammage of 110 g / m 2 or higher.
  • the bottom web or thermoplastic film used for manufacturing the cup-shaped box according to the invention has a thickness of 600 ⁇ m or less and therefore is much thinner than a bottom web known from the prior art.
  • the terms bottom web' and 'thermoplastic film' are used in present specification as synonyms.
  • the required rigidity of the cup is not only provided by the cup-shaped box, but also by the banderole that is much thicker than those known in the prior art. A certain rigidity of the cup is required to ensure a sufficient stackability of the cups, especially when they are filled with a substance to be packed and closed by sealing a lid on the upper rim of the cup.
  • the banderole is preferably made of a pulp or a thermoplastic polymer, or a laminate of a pulp film and a thermoplastic film.
  • the thermoplastic material is preferably chosen from oPP (oriented polypropylene) or oPS (oriented polystyrene).
  • the banderole is made of pulp, or in case of a banderole made of a laminate comprising a film of pulp and a thermoplastic film, the pulp is preferably paper, in particular kraft paper, or the pulp layer is a laminate comprising cellulose and an outer paper layer having improved printability.
  • a preferred banderole has a grammage of more than 110 g/m 2 up to 160 g/m 2 .
  • the inventive cup-shaped container i.e. the cup-shaped box with the banderole
  • the cup-shaped container according to the invention has a cup-shaped box with a thinner wall thickness, but thicker banderole preferably comprising pulp resulting in a reduction of thermoplastic material compared to containers know of the prior art.
  • thermoplastic material compared to containers know of the prior art.
  • the costs of the whole cup-shaped container is reduced compared to known containers of the prior art.
  • due to the reduced amount of thermoplastic material used for the inventive cup-shaped container its carbon footprint is also reduced.
  • said costs are also reduced compared to cup-shaped containers of the prior art.
  • the inventive cup-shaped containers have a reduced wall thickness of the box while keeping the rigidity of the containers by increasing the grammage of the banderole.
  • the rigidity of the cup-shaped container for providing a sufficient stackability of the container is measured by the maximum top load vertically applied to the upper rim of the cup-shaped container when decreasing the height of the container by 3 mm.
  • This top load is the maximum force that can be applied to the upper rim of the container when the container is vertically compressed by 3 mm.
  • the top load is a force as the pressure depends on the surface of the cup rim. Table 1: Comparison of top load results of different cup-shaped containers: container composition top load until decreasing height of container by 3 mm PS 850 ⁇ m + BD 95 g/m 2 65 N PS 500 ⁇ m + BD 130 g/m 2 110 N PS 600 ⁇ m + BD 130 g/m 2 136 N
  • PS 850 ⁇ m means a box made of a polystyrene film having a thickness of 850 ⁇ m and "BD 95 g/m 2 " means a banderole having a grammage of 95 g/m 2 .
  • PS 500 ⁇ m means a box made of a polystyrene film having a thickness of 500 ⁇ m and "BD 130 g/m 2 " means a banderole having a grammage of 130 g/m 2 .
  • PS 600 ⁇ m means a box made of a polystyrene film having a thickness of 600 ⁇ m.
  • the first row shows the test result of a commercially available cup-shaped container representing the prior art.
  • the second and third rows show results of an inventive container.
  • the carbon footprint as fossil balance has also been measured for different container compositions wherein the container comprises a cup-shaped box made of PS (height: 63 mm; diameter: 63 mm) and a banderole made of paper glued onto the shell of the box which data are shown in table 3, wherein the banderole encloses the complete outer face of the shell:
  • Table 3 container composition mass of container carbon footprint [g of emitted CO 2 ] ⁇ 5% PS, 850 ⁇ m + banderole 95 g/m 2 4.69 g 13.3 PS, 800 ⁇ m + banderole 95 g/m 2 4.5 g 12.7 PS, 600 ⁇ m + banderole 130 g/m 2 4.04 g 10.8 PS, 500 ⁇ m + banderole 130 g/m 2 3.62 g 9.6 PS, 600 ⁇ m + banderole 140 g/m 2 4.14 g 10.9 PS, 500 ⁇ m + banderole 140 g/m 2 3.73 g 9.7
  • PS means a box made of polystyrene having a height of 63 mm and a diameter of 63 mm.
  • the number before the ⁇ m reading means the thickness of the bottom web used for manufacturing the box.
  • the data after the term 'banderole' indicates the grammage of paper used for the banderole.
  • the thickness of the shell and that of the bottom of a cup-shaped box, or the thickness of a possible flange formed to the upper rim of the shell may differ to some extent, because said boxes are usually formed by thermoforming resulting in a box whose bottom and a possible flange are usually thicker than the thickness of the shell.
  • the improvement in the carbon footprint is about 18%.
  • the cup-shaped container according to the invention is especially suitable as yoghurt cup and is suitable to be used in FFS machines (FFS: form, fill, and seal).
  • FFS FFS machines
  • the shell of the box may be a cylinder, truncated cone or may have any other shape.
  • the cross-section through the shell may show a circle, an ellipse or may be polygonal.
  • the box is preferably formed by a deep-drawing process resulting in a circular, oval or polygonal bottom and a shell having typically a cylindrical or a truncated cone shape.
  • a flange may be molded at the free upper rim of the shell, i.e. the top of the box preferably has a flange for sealing a lid onto the top face of the flange.
  • the bottom and the shell of the box and in case of a flange molded to the upper rim of the shell also said flange are formed integrally in one-piece.
  • the box is preferably made of a bottom web or thermoplastic film having a thickness of between 200 to 600 ⁇ m. After forming the box, its wall thickness of the bottom, the shell and a possible flange lies preferably in the range of 100 to 600 ⁇ m.

  • Cups known in the prior art usually have a gap between the top of the banderole and the top of the box, because otherwise when using a standard banderole of 95 g/m 2 the banderole may be wrinkled at its top.
  • the inventive container requires a banderole of a certain thickness to ensure a sufficient load capacity (stackability). That is why a banderole that extends up to the top of the shell or up to the lower surface of a possible flange molded to the upper edge of the shell is preferred.
