Definitions

  • the invention relates to an opening aid for cardboard packaging, shipping folding boxes, shipping crates and the like, wherein the opening aid is formed as a perforation.
  • such covers are connected via a perforation with the hull of the cardboard so that the lid can be opened by tearing the perforation and the contents can be removed from the cardboard.
  • transport or outer packaging for storage and transport of a plurality of packaging such as bottles, cans, cartons, etc.
  • Such containers which are commonly referred to as carton boxes as well as sales assistants, also commonly referred to as shipping cartons, are commonly used in retailing.
  • sales units fulfill both the function of a transport protective overpack and later when placed in the business the function of a promotional presentation of the goods, without a separate presentation would be required.
  • the respective, any Cover carton even cut simply in such a way that the content for the customer, preferably in self-service stores, only visible.
  • Umverpackungslinen which can be converted with more or less great effort after transport and storage to sales helpers.
  • a tear tape is made up on the inside of the outer carton during manufacture, which is to be torn open before the goods presentation, so that the sales assistant is created.
  • the cartons may also be made from corresponding blanks having one or more parts such that the conversion from the clean packaging to the display sales unit is facilitated.
  • perforations are provided as an opening aid to allow opening of the folding cartons without additional aids such as a pair of scissors or a knife.
  • Such perforations represent a weakening of the material which reduces the stability of carton packages and shipping cartons, so that unintentional opening of the package during transport, storage or handling may occur.
  • the wall thickness or the material quality for example by better paper grades such as Kraftliner, the perforated wall must be increased, which leads to a higher material usage and thus costs and resource consumption.
  • the invention has for its object to provide an easy and convenient to handle opening aid of a container, namely a foldable packaging or carton and provided therewith a packaging / box, the opening aid without the aid of a tool to open the packaging / carton allow, but in comparison to a packaging / carton without opening aid requires little material.
  • an opening aid embodied as a perforation, which is designed as a perforation line bent at least in sections, whose material bridges or material gaps have a variable angle of attack relative to the perforation line.
  • the opening aid according to the invention is compared to conventional perforations high Stapelstauch- and Eindrückwiderstand. Furthermore, the inventive opening aid is suitable to be applicable and functional even with two or more multiwell corrugated board.
  • the opening aid represents a linear material weakening of material gaps and material bridges in the blank of the cardboard, which can be relatively easily destroyed by pushing in, pulling out, tearing and tearing, so as to ensure an easy separation or first opening, for example, a lid member.
  • the material weakening follows an imaginary line defined by the centers of the material bridges as support points.
  • the Perforationslinienverlauf is designed such that the perforation line forms a closed polyline in the assembled state of the packaging, so that the cardboard segment enclosed by the perforation line can be completely separated from the packaging. This is particularly advantageous in mailing boxes, whose front wall, top wall and parts of the side walls are usually separated for the purpose of product presentation and product removability on a shelf.
  • the perforation line extends in an arcuate manner over the side walls of such shipping folding boxes.
  • Particularly advantageous here is a parabolic design of the perforation line.
  • the perforation line formed as a closed polyline is designed as a continuous function which has at least four inflection points over its course. It is advantageous to provide each two turning points mirror symmetrical to a front wall, which forms an intermediate wall between side walls and head walls, respectively at the lower end of a side wall and in the top wall.
  • the material bridges or gaps of the opening aid according to the invention do not run tangentially to the perforation line, but have a different orientation from the tangential to the perforation line. This orientation, which deviates from the tangential, can be described by the angle of attack ⁇ .
  • the angle of attack ⁇ is defined as the acute angle, which is formed by the tangent of the Perforationslinienverlaufs and the tangent of the gap in the material gap in the piercing point (crossing point) of the perforation line and material gap.
  • the angle of attack ⁇ over the course of the perforation line to a variable size. Its size thus changes from material gap to material gap. This achieves and configures an optimum ratio between the greatest possible transport stability and the smallest possible tearing force necessary to open the perforation line.
  • the angle of attack ⁇ for example, in the area of top bottles very pointed, so be formed sharper than in other areas, since in this area the package has little load to bear, but a comparatively easy and clean tearing of the perforation is advantageous, while the angle of attack ⁇ in the range of side walls over the longest possible path of the perforation line parallel to the shaft alignment of a corrugated cardboard having the perforation and thus realizes the highest possible Stapelstauchwiderstand.
  • the angle of attack ⁇ is chosen such that the force vector acting on the material gap when the opening aid tears open forms an angle ⁇ between the material gap and the force vector of 75 to 105 °.
  • An inventive container is preferably made of paper, cardboard, corrugated cardboard and / or cardboard.
  • the opening aid according to the invention is particularly suitable for one-, two- and other multi-shaft boards.
  • a paper should preferably have good printability and foldability and have suitable stability. Furthermore, the paper should be suitable for processing in automated manufacturing processes such as erecting and filling plants.
  • the foldable paper can be a variety of papers on which a perforation can be formed.
  • a carton should also have good printability, foldability and proper stability. Furthermore, the board should be suitable for processing in automated manufacturing processes such as erecting and filling plants. Any foldable perforatable paperboard material may be provided.
  • a cardboard should have suitable foldability and appropriate stability. Furthermore, the board should be suitable for processing in automated manufacturing processes such as erecting and filling plants.
  • a cardboard can be corrugated or solid board.
  • Fig. 1 shows a blank for a product outer packaging made of cardboard. Such a cardboard is also referred to as a shelf-ready box.
  • the blank 1 has a first side wall 6a, a second side wall 6b and a front wall 7a and a rear wall 7b.
  • the blank 1 is formed into a tube, that is to say into an annularly closed body, which initially leaves open end faces.
  • head bottles 8a, 8b, 9a, 9b are pivotally arranged, which cover the head opening, so the one open end of the tube at least partially in the assembled state of the product outer packaging.
  • the blank 1 has an opening aid formed by a perforation line 2.
  • the perforation line 2 extends mirror-symmetrically with respect to the front wall 7a and the top flap 9a from the front wall 7a via the side walls 6a and 6b as well as via the top flaps 8a and 8b.
  • the perforation line 2 forms in the assembled state of the blank 1 a closedhan, which includes areas of the front wall 7a, the side walls 6a, 6b and the head lugs 8a and 8b.
  • the front wall 7a has at its bottom end on a handle opening 5, through which a user can intervene to rupture of the limited area by the perforation line 2.
  • the course of the perforation line 2 has in each case a first inflection point 10a or 10b in the lower region of the side wall 6a or 6b.
  • a second inflection point 11a or 11b is arranged on the top flap 8a or 8b. Between the two turning points 10a, 11a and 11a, 11b, the perforation line 2 extends with sections 2a and 2b in approximately parabolic.
  • Fig. 2 shows a detailed view of the perforation line 2 and its course over the front wall, a side wall and a top flap.
  • the perforation line 2 consists of material gaps 3 and material bridges 4, wherein the material gap 4 is formed like a line in the manner of a slit.
  • the dash-dot lines shown and labeled W indicate the shaft alignment of a corrugated board from which the blank 1 is formed. The dash-dot lines W thus run parallel to a wave trough or wave crest of the corrugated board.
  • strip-shaped material gaps 3 extend in the lower region of the perforation line 2 essentially parallel to the shaft alignment W, wherein they have an orientation deviating from the parallel in the upper region.
  • Fig. 3 shows a detailed view of the perforation line 2 with voltage applied to the material gaps 3 force vectors, which act in each case when tearing the opening aid on the material gaps 3.
  • the angle of attack ⁇ is selected such that the force vector acting on the line-shaped material gap 3 when the opening aid is torn forms an angle ⁇ between the material gap 3 and the force vector of 75 to 105 °, ie the force vectors are at the line-shaped material gaps 3 at such angles ⁇ .
  • the course of the angle of attack ⁇ between the first inflection point 10 and the second inflection point 11 is well based on Fig. 4 to recognize.
  • the material gaps 3 are initially directed parallel to the wave orientation W, while they tilt in the upper region to the perforation line 2, the latter extending in an increasingly curved area in a central region.
  • the course of the perforation line 2 and the orientations of the material gaps 3 are such that the angle of attack ⁇ changes from material gap to material gap.
