Definitions

  • the invention relates to a blank for a packaging shell of a cup packaging.
  • the invention likewise relates to a cup packaging having a packaging shell.
  • the invention furthermore relates to a method for separating a cup packaging from a packaging shell and to a method for producing a blank.
  • a blank for a packaging shell of a cup packaging having a base, a rim opposite the base and a wall between the base and the rim, the blank being suitable for encasing the wall in order to form the packaging shell; the blank having:
  • the blank provides the advantage that the blank can be easily and reliably separated from a cup packaging in particular because of the at least one front incision and the at least one back incision.
  • the combination of the at least one front incision and the at least one back incision can provide a material weakness, simplifying the separation of the separation section.
  • the separation section can be easily separated by hand and/or by machine.
  • the separation of the blank can be guaranteed. Therefore, the blank can be separated from the residual material of the cup packaging such that an environmental-friendly disposal can be achieved. Consequently, the blank can contribute to the environmental protection. Simultaneously, the stabilization of the blank during use as a packing shell can be ensured.
  • the blank can minimize the risk of injury on the blank.
  • the blank can be easy to stack or transport, respectively, as well as easy to feed to a machine and to be stored in the latter for attaching to a cup packaging.
  • the blank for the packaging shell preferably can have a planar carrier material which can be produced at least from pulp, cellulose, cardboard, paper, recycled material, wastepaper, plastics material, metal and/or similar, or combinations therefrom, respectively.
  • the carrier material can be coated and/or can be produced in layers and/or from various materials/primary products.
  • the carrier material along the face thereof can also in regions/portions have various materials/primary products and/or layers; in particular, at least one connection portion (or else both) can be configured in a manner different from that of the remaining carrier material.
  • the blank can be preferably at least substantially quadrangular.
  • the blank can alternatively or additionally be in the shape of an annular portion.
  • the blank can be typically configured so as to be planar, able to be spread out in a planar manner and/or able to be spread out in planes.
  • the blank can be preferably configured so as to be integral.
  • the primary material for the blank can be typically present in the form of sheets and/or wound on rolls, wherein the blank can be preferably punched and/or cut out from said primary material.
  • the blank typically can have at least one or exactly one front side and one rear side.
  • the peripheries, the front side and the rear side moreover typically entirely can delimit the blank in terms of the volume of the latter.
  • the peripheries preferably can delimit the blank, or the carrier material, respectively, at least substantially in a planar manner.
  • the peripheries can be preferably, at least substantially and/or in portions, configured so as to be linear, curved, rectilinear and/or arcuate and/or in the transition to the respective next/preceding periphery can have rounded corners, for example.
  • two peripheries can be at least substantially arcuate and two peripheries can be at least substantially rectilinear, wherein one of the rectilinear peripheries, for example centrically, can contain an arcuate protrusion or a tab, respectively.
  • the first periphery on the carrier material can be diametrically opposite the second periphery; the lower periphery on the carrier material can be diametrically opposite the upper periphery.
  • Diametrically opposite can mean that the peripheries in relation to the carrier material substantially can represent external regions having the carrier material therebetween.
  • the upper periphery can be longer than the lower periphery, in particular also longer than the first and the second periphery.
  • the separation section comprises the central separation portion, the upper separation portion, and the lower separation portion.
  • the central separation portion, the upper separation portion, and the lower separation portion can define the separation section and thereby can define the region, where the blank can be separated.
  • the upper separation portion is arranged above the central separation portion. In other words, the upper separation portion can be arranged closer to the upper periphery than the central separation portion.
  • the lower separation portion is arranged below the central separation portion. In other words, the lower separation portion can be arranged closer to the lower periphery than the central separation portion.
  • the central separation portion, the upper separation portion and the lower separation portion can be separated from each other in the direction from the upper periphery to the lower periphery.
  • the central separation portion, the upper separation portion and the lower separation portion can overlap.
  • the upper separation portion can overlap with the central separation portion and/or the lower separation portion can overlap with the central separation portion.
  • the at least one front incision can be arranged on the front side of the planar carrier material.
  • the at least one front incision can be arranged on the outside of the blank, when the blank can be formed to a packaging shell.
  • the at least one front incision can be a material thinning in the blank.
  • the at least one front incision can be a material removal.
  • the at least one front incision can be half cut.
  • the at least one back incision can be arranged on the back side of the planar carrier material.
  • the at least one back incision can be arranged on the inside of the blank, when the blank can be formed to a packaging shell.
  • the at least one back incision can be a material thinning in the blank.
  • the at least one back incision can be a material removal.
  • the at least one back incision can be a half cut.
  • the at least one opening can be a material recess.
  • the at least one opening can be configured for a manual use, in particular such that the blank can be removed from a cup packaging by hand.
  • the at least one opening can be an interruption in the blank.
  • the at least one opening can be an engagement portion which can be used for manual or mechanical separation of the separation section.
  • the at least one opening can be an engagement portion which can trigger the separation of the separation section.
  • the at least one opening can have a width of 5 mm in a direction from the first periphery to the second periphery.
  • the separation section can tear as a result of a notching effect which can facilitate the tearing of the carrier material at one end of the separation section, when the carrier material can be at least in part stressed for tension in a planar direction.
  • the separation section can form in particular a local material weakness according to which the separation section can be exposed to greater forces than the surrounding carrier material when the carrier material can be impinged with a force.
  • At least partially extending from the lower periphery to the upper periphery can mean that the at least one front incision and the at least one back incision can comprise a shape which mostly extends in the direction from the lower periphery and the upper periphery.
  • the at least one cut can be a material separation in the blank.
  • the at least one cut can be a material recess in the blank.
  • the at least one perforation can be a discontinuous material separation in the blank.
  • the at least one perforation can be formed by multiple material recess in the blank, for example by holes aligned in a row.
  • the at least one front incision of the lower separation portion can be connected to the to the at least one opening and/or to the lower periphery.
  • the connection can be established by the at least one cut or the at least one perforation or a combination of the at least one cut and the at least one perforation.
  • the stabilization of the blank during use as a packing shell can be ensured, while at the same an easy separation of the blank can be guaranteed.
  • the environment can be protected.
  • the depth of the at least one front incision and the at least one back incision of the upper separation portion and/or of the lower separation portion can be 35 % - 90 % of the thickness of the planar carrier material, the at least one front incision and the at least one back incision can provide a very reliable material weakness. Hence, a good separation of the separation section can be guaranteed so that the blank can be environmentally friendly.
  • a cup packaging having a base, a rim opposite the base and a wall between the base and the rim, and a packaging shell, wherein the packaging shell is disposed in an encircling manner around the wall between the base and the rim wherein the packaging shell is made of a blank according to the invention.
  • the four cuts 22 connect the front incision 19 of the lower separation portion 18 to the opening 21 and to the lower periphery 10.
  • the front incision 19 of the upper separation portion 17 and the back incision 20 of the upper separation portion 17 are spaced apart in a direction A from the first periphery to the second periphery.
  • the front incision 19 of the lower separation portion 18 and the back incision 20 of the lower separation portion 18 are spaced apart in a direction A from the first periphery to the second periphery.
  • the depth of the front incisions 19 and the back incisions 20 of the upper separation portion 17 and of the lower separation portion 18 are the same.
  • the depth of front incisions 19 and the back incisions 20 of the upper separation portion 17 and of the lower separation portion 18 are 35 % - 90 % of the thickness of the planar carrier material 4.
  • the depth could also be 50 % - 75 % of the thickness of the planar carrier material 4.
  • the back side of the carrier material 4 in the first connection portion 13 is provided for adhesively bonding to the front side of the carrier material 4 in the second connection portion 14.
  • An adhesive 23 is applied to the front side of the carrier material 4 in the second connection portion 14.
  • the adhesive 23 can be applied to the back side of the carrier material 4 in the first connection portion 13.
  • the adhesive 23 has a width of 5 - 9 mm.
  • the separation section 15, in particular the upper separation portion 17, the central separation portion 16 and/or the lower separation portion 18, is disposed next to the first connection portion 13.
  • connection portion 13 does not adapt to the frustoconical, convex wall 34 in the same manner as the carrier material 4 between the connection portions 13, 14.
  • the opening 21 in the separation section 15 is slightly spread apart. This means that the carrier material 4 which was originally directly opposite the opening 21 and separated at the latter is mutually diverged in portions, this resulting in a gap for easier engagement being configured.
  • the packaging shell 2 is not adhesively bonded to the cup packaging 3. Rather, the blank 1 is adhesively bonded only to itself so as to configure the packaging shell 2.
  • the packaging shell 2 is held on the cup packaging 3 by way of a form-fit because the wall 34 is radially recessed in relation to the periphery of the base 33, or a base protrusion 48, respectively, and the flange 30, or a flange protrusion 47, respectively, and because the packaging shell 2 is disposed so as to be tightly wound on/onto the wall 34.
  • the packaging shell 2 is thus fixed between the flange 30 and the base 33 by way of a form-fit.
  • the cup packaging 3 of Fig. 4 has a height 35 of 90 mm.
  • the wall 34 above the beaker height, or along the direction 35, respectively, has a height 36 of 86 mm.
  • the base protrusion 48, or the base 33, respectively, has a height 37 of 2 mm, and the flange protrusion 47, or the flange 30, respectively has a height 38 of 2 mm.
  • the base 33 has a diameter 39 of 56 mm including the double width 41 of the base protrusion 48 of 1 mm. Without the base protrusion 48, the base 33 has a diameter 45 of 54 mm.
  • the flange 30 In relation to the base 33 the flange 30 has a "significantly" larger diameter 40 of 80 mm, this including the double width 42 of the flange protrusion 47 of 5 mm. Without the flange protrusion 47, and not taking into account the wall 34 which is only 0.2 mm thick, the flange 30 has an internal diameter, or the opening 31 in the flange 30 has a diameter 43 of 80 mm, respectively.
  • the angle 44 of the wall in relation to the base in the exemplary embodiment is 84° +/- 1°.
  • Fig. 5 shows a first method according to the invention shortly before a cup packaging 3 is compressed. It is illustrated that one upper face 49 of two faces 49, 50 of a press in a direction 52 can converge in parallel with the lower face 50, said direction 52 in principle corresponding to the direction 35, or being disposed parallel to the latter, respectively.
  • the cup packaging 3 standing on the base 33 thereof is disposed between the two faces 49, 50, said cup packaging 3 moreover having a packaging shell 2.
  • the packaging shell 2 is produced from a blank 1, has a separation section 15 and is not adhesively bonded to the cup packaging 3.
  • the cup packaging 3 of Fig. 4 can be separated from the packaging shell 2 thereof in that the separation section 15, is completely split because the separation section 15 "bursts" under a large deformation of the cup packaging 3.
  • Fig. 6 shows a second method according to the invention which substantially corresponds to the method of Fig. 5 .
  • the cup packaging 3 by way of the wall 34 thereof, or the packaging shell 2 disposed thereon, respectively, substantially bears on the lower face 50.
  • the cup packaging 3 can only be partially compressed and crushed in one direction, thus only by way of one directional component along the direction 35, from the flange 30 towards the base 33, or from the base 33 towards the flange 30.
  • this method can also typically separate packaging shells 2 with a separation section 15, and/or packaging shells 2 that are not adhesively bonded to the wall 34, respectively, from the wall 34 or from the cup packaging 3, respectively.
