Definitions

  • Frozen food can be packed in flexible and rigid containers.
  • solid or rigid packaging it can be, for example, folding boxes that essentially consist of cardboard material.
  • Such a folding box normally represents a cuboid that contains three dimensions: length I, width b and height h.
  • the opening mechanism of such a packaging is an important function for the consumer, on the one hand to be able to easily empty the packaging. On the other hand, this mechanism can also make the packaging resealable. The latter case is particularly important if the consumer does not consume the contents of the packaging at once.
  • An example of this are frozen herbs arranged in such a packaging, which are only needed in small quantities by the consumer, so that the packaging can be opened and closed again more frequently. Easy to open and reclosing of the packaging are an essential criterion here. In addition, the packaging must remain securely closed during logistics and must not be opened unintentionally due to normal transport conditions.
  • Such packages are often provided with an opening line predetermined by a perforation.
  • the packaging can be opened, namely torn open, along the perforation.
  • Typical packaging is a resealable folding box, also known as a click box.
  • This is equipped with a large opening lid (cf. Fig. 1 ).
  • the cuboid folding box can have different dimensions in terms of length I, width b and height h, e.g. lxwxh: 88mmx68mmx72mm.
  • the lid is lowered over a main container on three sides and glued to it in three places: at the front below a perforation 1 and in two laterally located positions 2. This also ensures a tamper-evident seal.
  • the typical handling when opening is shown: The container is held with the left hand and the lid is pushed open with the thumb of the right hand in the direction marked F2.
  • the result of the opening process is shown, with the laterally glued parts of the folded-over cover 2 surrounding the cuboid remaining glued.
  • the perforation 1 is torn open and the cover 2 is lifted up in the direction designated by F2 in accordance with the force applied and pivoted about the pivoting path 5.
  • the two perforations 3 on the sides of the cuboid must be easy to tear open.
  • the same perforation 3 must again be sufficiently resistant and not open through lateral pressure F1. In other words, when a force is applied in the direction of F2, the perforation should open slightly and when a load is applied in the direction of F1, the resistance should be as great as possible.
  • this object is achieved by cardboard packaging with a perforation, the perforation, in particular the lateral perforation, being divided into zones.
  • the perforation connects two surface sections of the cardboard packaging that are subdivided by the perforation, in particular separated from one another.
  • one of the surface sections can be part of a lid of the cardboard packaging, in particular a side flap of the lid and / or a surface perpendicular to the lid surface.
  • the perforation is advantageously arranged on one side of the cardboard packaging in a corner section of the cardboard packaging, the perforation running in particular from a first point on the cardboard packaging to a second point on the side, the second point in particular being closer to the corner than the first point and / or the first point is closer to the midpoint of the page than the second point, the perforation in particular being curved from the first to the second point.
  • the perforation has gates, each in particular forming recesses, in particular holes, in the cardboard packaging, with a gate width and webs, which in particular represent part of the material cardboard packaging, with a web width.
  • the web width is to be understood as the extension of the web in the direction of the perforation.
  • the gate width the extent of the gate in the direction of the perforation.
  • the webs of the perforation are separated from one another by the gates of the perforation.
  • the perforation has an alternating web and a gate.
  • the webs and / or the gates have a length in particular perpendicular to the width. In particular, the length of the gates is the same as that of the webs, in particular the adjacent webs.
  • the length and / or the lengths are constant over the direction of the perforation.
  • the length of the webs and / or the recesses is in the range from 0.3 mm to 3 cm, in particular up to 3 mm.
  • the webs and / or gates have a height in particular perpendicular to the width and length.
  • the height of the webs is advantageously equal to the gates.
  • the heights of all webs and / or cuts of the perforation are constant over the direction of the perforation.
  • the height is in the range of less than 50% of the length and / or width of the webs and / or gates, in particular between 10 mm, in particular 13 mm, and 5 cm, in particular up to 3 mm.
  • the cardboard packaging is also set up to be torn open along the perforation in a direction in which the perforation runs, which locally corresponds in each case to the tear direction of the cardboard packaging.
  • the cardboard packaging is opened, for example by rotating the lid, which is now at least partially no longer connected to the rest of the cardboard packaging, in such a way that an opening is produced through which the contents of the cardboard packaging can be accessed and / or through which can be inserted into the space contained in the cardboard packaging.
  • the rotation takes place, for example, about an axis of rotation which is arranged perpendicularly on the perforation and / or on the surface sections of the cardboard packaging that are subdivided by the perforation.
  • the perforation is divided into different zones, the perforation beginning with a first zone in the direction of the perforation.
  • This first zone in turn begins in the direction of the perforation with a gate or with a starting web with an extremely small web width in the direction of the perforation before a cut, the The web width of the starting web has the smallest web width, in particular a web width of a maximum of 1 mm, in particular in comparison to the web widths of all further webs of the perforation.

  • the web width of the initial web is irrelevant and therefore does not represent the smallest web width of the webs to be compared.
  • the first zone is followed, in particular immediately, in the direction of the perforation by a further, in particular second, zone, which represents a stable core zone that forms a central part of the perforation and is equipped with webs of greater web width, and / or follows in the tear direction, in particular immediately after the first or the stable core zone a further, in particular third, zone, which in particular represents a directional zone which, in particular for the purpose of directional determination, has at least one web of smaller web width of the perforation, and / or follows, in particular immediately after the first or the stable core zone or the directional zone has another, a stable end zone with webs of greater web width.
