Definitions

  • the present disclosure relates a packaging material. More particularly the present invention relates to a carton-based packaging material for forming a package, and a package.
  • Packaging material used for producing individual packages for e.g. liquid food is well known in the art, and has been a commercial success for many years due to cost-efficient manufacturing and superior quality in terms of robustness, food safety, etc.
  • the packaging material is a sheet-like material entering the filling machine either as a continuous web of packaging material, or as separate blanks.
  • the package is formed by sealing and folding the package material; the result is a closed package having a distinct shape, such as a parallelepipedic shape.
  • the package is opened, and the content is poured out from the package.
  • the discharge rate is decreasing as the content level inside the package decreases. Especially if the dimensions of the package opening are small, it may take some time to empty the package completely.
  • the present disclosure may be said to, according to a first aspect thereof, relate to a packaging material in accordance with claim 1 .
  • a package in accordance with claim 13 is provided. Preferred embodiments are defined by the appended dependent claims.
  • FIG. 1 is an isometric view of a package being formed by a packaging material according to an embodiment
  • FIG. 2 is an isometric view of a package being formed by a packaging material according to another embodiment
  • FIG. 3 is a front view of a packaging material being used to form the package shown in FIG. 1 ;
  • FIGS. 4 a - d are side views of the package shown in FIG. 2 during an emptying process.
  • FIG. 1 a package 10 is shown.
  • the package 10 is formed by folding and sealing a package material (see FIG. 3 ) in accordance with an embodiment.
  • the package 10 is a so called gable top, having an opening provided at its upper end 5 .
  • the upper end 5 is connected to four lateral walls; a front side 2 , a back side 3 , and tow lateral side walls 4 a - b .
  • the four lateral walls 2 , 3 , 4 a - b are connected at their lower edge by a bottom end 6 .
  • the four lateral walls 2 , 3 , 4 a - b form panels P 1 -P 4 which are pre-defined in the packaging material 1 prior to manufacturing of the package 10 .
  • the back side 3 corresponding to panel P 1 , is provided with a horizontal crease line H arranged at the lower half of the package 10 , approximately at a height corresponding to half the width of the bottom end 6 .
  • the lateral side walls 4 a - b are each provided with a vertical crease line F.
  • the vertical crease line F is separated into two crease lines arranged along a common axis, and being separated at the centre part of the package. Separation is preferred in order to maintain the robustness of the package 10 at this centre area; otherwise there may be an increased risk of bulging.
  • the horizontal crease line H facilitates folding of the bottom end 6 upwards towards the back side 3 .
  • the vertical crease line F facilitates folding of the lateral side walls 4 a - b inwards in order to flatten the package 10 upon emptying. Hence, it will be possible to empty the package 10 in a facilitated manner, especially if the package 10 is filled with high viscous food product such as yoghurt or similar.
  • FIG. 2 another embodiment of a package 10 ′ is shown.
  • the package 10 ′ is here represented by a flat-top package commercially known as Tetra BrikTM.
  • the package 10 ′ shows great similarities with the package 10 previously described with reference to FIG. 1 .
  • one panel P 1 forming the front side 2 is provided with the horizontal crease line H, while the lateral side walls 4 a - b are provided with a respective vertical crease line F.
  • the horizontal crease line H may be provided on the back side 3 or on the front side 2 of the package 10 , 10 ′.
  • the packaging material 1 may e.g. be provided as a separate blank, or as a part of a continuous web of packaging material 1 .
  • the packaging material preferably has a multilayer structure comprising a base layer, e.g. of paper, covered on both sides with layers of heat-seal plastic material, e.g. polyethylene.
  • the packaging material also comprises a layer of oxygen-barrier material, e.g. an aluminium foil, which is superimposed on a layer of heat-seal plastic material, and is in turn covered with another layer of heat-seal plastic material forming the inner face of the package eventually contacting the food product.
  • the packaging material has a first set of crease lines T configured to form an upper end of the package 10 , 10 ′ when the packaging material 1 is folded along said first set of crease lines T, and a second set of crease lines B configured to form a bottom end of the package 10 , 10 ′ when the packaging material 1 is folded along said second set of crease lines B.
  • first and second set may be designed according to the desired appearance and dimensions of the final package.
  • the two different packages 10 , 10 ′, described previously require different sets of crease lines for forming the upper end and the bottom end.
  • a third set of crease lines V 1 -V 3 is provided.
  • the crease lines V 1 -V 3 are separated in order to define longitudinal panels P 1 -P 4 extending in between said crease lines V 1 -V 3 .
  • the panels P 1 -P 4 correspond to the four lateral walls 2 , 3 , 4 a - b of the final package 10 , 10 ′.
  • At least a first panel P 1 is provided with the horizontal crease line H, and at least one second panel P 2 , P 4 , being arranged adjacent to said first panel P 1 when the package 10 , 10 ′ is formed, is provided with at least one vertical crease line F.
  • the crease lines V 1 -V 3 preferably extend between the first set of crease lines T and the second set of crease lines B.
  • the crease lines V 1 -V 3 extend into the first and second set of crease lines T, B such that only a part of the crease lines V 1 -V 3 assist in defining the panels P 1 -P 4 arranged in between.
  • the vertical crease line F is preferably provided as two crease lines Fa, Fb extending along a common axis, but being separated from each other in a longitudinal direction.
  • the separation distance between the two vertical crease lines Fa, Fb may e.g. be less than the individual length of at least one of said two vertical crease lines Fa, Fb.
  • the two vertical crease lines Fa, Fb have equal length.
  • the vertical crease lines Fa-b extend along a centre line of said panel(s) P 2 , P 4 .
  • the total length of the vertical crease line F may be between 20-80% of the total height of the package 10 , 10 ′ when formed, and the total length of the horizontal crease line H may e.g. exceed 50% of the width of its associated panel P 1 , P 3 .
  • the horizontal crease line H extends across the entire width of its associated panel P 1 .
  • the horizontal crease line H is arranged at a distance from the upper longitudinal end of the second set of crease lines B, said distance being equal to the longitudinal extension of the second set of crease lines B.
  • FIGS. 4 a - d folding of a package 10 ′ will be described. However, the folding process is also applicable for the package 10 shown in FIG. 1 .
  • the package 10 ′ is shown during normal conditions, i.e. its intended parallelepipedic shape is maintained.
  • the bottom end 6 is folded upwards along the horizontal crease line H.
  • FIG. 4 b This is shown in FIG. 4 b .
  • the lateral side walls 4 a - b are urged slightly inwards, such that they may fold inwards along the respective vertical crease line F.
  • FIG. 4 c the package 10 ′ is shown in which folding has been performed such that the upper end 5 starts to deform as a result of the lateral side walls 4 a - b being folded even further inwards.
  • the package 10 ′ has been flattened significantly such that the remaining food product may be discharged in a very efficient manner.
  • the reduced size of the flattened package 10 ′ provides additional advantages.
