Definitions

  • the invention relates to packaging material according to the preamble of patent claim 1 and to packaging according to the preamble of patent claim 14.
  • packaging material which consists of normal corrugated cardboard with a corrugated core layer and flat cover layers on both sides.
  • the blank is provided with molded folding grooves to fold the packaging material around the door leaf in such a way that the sensitive, narrow longitudinal edge areas with their folds and any fittings are protected and clean, flat and straight narrow sides are created in the packaging.
  • This packaging material is expensive because the operating costs of a corrugated cardboard manufacturing machine for normal corrugated cardboard are high, because cutting is a time-consuming operation in expensive machines, and because the disposal costs of the packaging material are high because they depend on the volume or weight.
  • a method and apparatus for making packaging blanks from normal, i.e. Corrugated cardboard with flat cover layers on both sides are known from EP 0 541 953.
  • the sensitive longitudinal edge area of a door leaf is only insufficiently protected, because if the corrugation runs in the direction of the longitudinal edge area, the stack-dent compressive strength and the crush resistance of the corrugated cardboard are low there.
  • there is a rounded course of the single-sided corrugated cardboard which gives an unsightly and improvised visual impression when the door leaves are stacked one on top of the other, packed in this way, despite the internal corrugation.
  • Packaging for single-sided corrugated cardboard that looks like the lid of normal boxes and in which the objects are placed is also used for bottles or other fragile items, whereby they may be stacked on top of each other in groups.
  • the dimensional stability of the packaging is low and little strength can be achieved laterally and in the vertical direction of the packaging sides.
  • Methods and devices for producing blanks from corrugated cardboard on one side for packaging are known from CH-PS 407 723 and DE-GM 19 10 354, folding grooves being embossed or incised transversely to the direction of the corrugation.
  • the invention has for its object to provide a packaging material or a packaging made of single-sided corrugated cardboard which, despite similarly good usage properties as normal corrugated cardboard, is less expensive than packaging material or packaging made from normal corrugated cardboard, with the aim being to pack objects in a well-protected manner to be able to.
  • the object is achieved according to the invention with the packaging material with the features of claim 1 and with the packaging with the features according to claim 14.
  • One-sided corrugated cardboard can be produced inexpensively and - which is not possible with normal corrugated cardboard - can be processed from a roll.
  • the one-sided corrugated cardboard is so stiffened by the reinforcement that it has at least the same usage properties as normal corrugated cardboard.
  • stack-proof pages are created in the packaging that are straight and level, which, despite the folding grooves, cannot be achieved without corrugated cardboard on one side without reinforcement.
  • the packaging material is tear-resistant and pressure-stable. In the other areas, which are not covered by the reinforcement, the packaging material is unfinished.
  • the packaging has practically the same properties for packaging plate-shaped objects as the expensive packaging made of normal corrugated cardboard, because the reinforcement is effective in the dent-resistant areas, where clean and flat and dent-resistant side surfaces are used, which also contributes to the formation of clean folded edges. In addition, there is a high level of compressive strength with good crack resistance and compressive strength in these areas. In the areas without reinforcement, the packaging serves to cover areas of the packaged object, for which normal corrugated cardboard was actually overqualified. The reinforcement is easy to apply. The additional effort for the reinforcements is negligible in view of the savings in the production of the one-sided Corrugated cardboard, when storing or processing single-sided corrugated cardboard into packaging and especially when disposing.
  • each reinforcement can already be attached when the single-sided corrugated cardboard is manufactured. If formatted blanks are formed from the single-sided corrugated cardboard, the reinforcements and, if applicable, the folding grooves can also only be attached when the blank is being produced.
  • the reinforcements lying transverse to and with the shaft form a frame in which the strength of normal corrugated cardboard is present, while the remaining surface retains the advantage of one-sided corrugated cardboard.
  • the flat reinforcement is only glued to the shaft crests. This creates a limited area of stable normal corrugated cardboard in the one-sided corrugated cardboard or, if the reinforcement is stronger than the flat top layer, a specially reinforced and stiffened area.
  • the materials for reinforcement specified in claim 4 are inexpensive and easy to process.
  • the embodiment according to claim 5 is particularly expedient because no material separation is required for disposal.
  • the embodiment according to claim 6 is used to form different packaging sizes from a blank. Only selected reinforcements are used for stiffening. A blank can therefore be used for objects of different sizes.
  • the embodiment according to claim 8 can be expedient.
  • the configuration of the folding grooves can be expedient.
  • the packaging material according to claim 10 can also be used for the production of different packaging sizes, with the right pair of folding grooves then being used within the entire strip-shaped surface area to form a stiffened packaging side.
  • the reinforcement is used here as a carrier for another packaging material, for example in order to embed or protect particularly sensitive edges or projections.
  • the embodiment according to claim 12 has the advantage of inexpensive production, space-saving storage, easy transport and a small space requirement for the end user, who separates the used sections for the packaging from the rolled web.
  • the embodiment of the packaging according to claim 15 is characterized by stiffened side areas of the packaging with precisely formable folding edges.
  • the reinforcement is on the inside, which avoids the risk of being packed when stacked Objects will be damaged if the reinforcements slip together.
  • one and the same packaging can be used for objects of different sizes by using the pair of folding grooves suitable for the dimensions of the objects to be packed in order to form a side surface of the packaging.
  • the packaging is part of an endless web, which is advantageous in terms of production, transport and storage.
  • the packaging according to claim 18 is a formatted blank, which is provided in rolled or flat form.
  • the folding grooves and the reinforcements can be provided when producing the blank.
  • the packaging according to claim 19 has reinforced areas on all sides, stable tabs and an integrated stiffening frame.
  • the single-sided corrugated cardboard is only present in the less contaminated remaining area.
  • 1 is either an endless, rollable or rolled web B or a formatted blank Z. It consists of single-sided corrugated cardboard W of any type with a flat top layer D (FIG. 10) and a laminated corrugated layer K. Im Blank Z, longitudinal edges 1, 2 and transverse edges 3, 4 can be seen. The corrugation, indicated by wave crests 6 ', runs parallel to the edges 3, 4, provided that the wave crests 6' run in a straight line and parallel to one another. However, it is also conceivable to use one-sided corrugated cardboard W in which the corrugated crests do not run in a straight line but in a corrugated manner in the surface (indicated at 6 ′′ in FIG. 12).
  • Parallel folding grooves 8, which belong together in pairs, are formed parallel to the edges 1, 2, either from the corrugated side 5 and / or from the smooth side 7.
  • the strip-shaped surface area defined between a pair of folding grooves 8 is covered on the corrugated side 5 by a flat reinforcement 9, which is glued at least on the corrugation crests 6 'and extends between the edges 3, 4.
  • the reinforcement is, for example, a paper, cardboard, plastic, fabric or non-woven strip, which should expediently be able to roll similarly to single-sided corrugated cardboard W.
  • a packaging V formed from the packaging material M from FIG. 1 has a lower bottom region 10, in which the shafts 6 are exposed on the inside.

  • the packaging V is stack pressure-resistant in the area of the pages 11.
  • the sides are flat. The side edges are clean and straight.
  • the packaging material M according to FIG. 3 is used to produce, for example, a rectangular folding box packaging V according to FIG. 4.
  • the packaging material M can be cut off from an endless web B (indicated by dashed lines) or be a formatted blank Z.
  • the surface area defined by the folding grooves 8 running perpendicular to the shafts 6 is covered by the reinforcement 9. Slots 13 form tabs 14 which can be folded over the folding grooves 8. End flaps 14, if provided, serve to close the packaging.
  • the reinforcement 9 is applied to the corrugated side 5. 4, the side walls indicated by 15 are stiffened, while the upper and lower sides of the packaging formed by the tabs are not stiffened.
  • the packaging V is intended for glasses or similar objects, for example.
  • the packaging material M or the packaging V according to FIGS. 1 and 2 is preferably used for packaging plate-shaped objects such as door leaves T1 and T2 shown in FIG. 6.
  • the packaging material M or the packaging V according to FIGS. 1 and 2 is designed for a certain door size, the reinforcements 9 in their width defined by the folding grooves 8 being matched to the width of the narrow longitudinal edges of the object to be packed.
  • a packaging material M is indicated with which packaging V for objects T1 and T2 of different sizes, e.g. Door leaves, let form.
  • packaging V for objects T1 and T2 of different sizes e.g. Door leaves, let form.
  • several pairs of folding grooves 8 are provided transversely to the direction of the shafts 6, between which strip-shaped reinforcements 9, 9 'are glued on the shaft side.
  • Objects T1 and T2 are door leaves with fitting receptacles 17 and fitting parts 18 on their longitudinal edges 19 which are narrow in comparison to the main dimensions and which are optionally also provided with folds 20.
  • the packaged door leaves must be stacked on top of each other.
  • the door leaves T1 and T2 differ in width. Both types can be packed with the packaging material M of FIG. 5.
  • the upper door leaf T1 is packed in the upper packaging V, in which the reinforcements 9 lie in the side areas, while the reinforcements 9 'point towards the underside of the door leaf.
  • the narrower door leaf T2 is packaged in the lower packaging V, in which the reinforcements 9 'lie in the side areas. while the reinforcements 9 rest on the top of the door leaf T2. In the area 16, the folded ends may then overlap.
  • the packaging material M according to FIG. 7 serves to produce two packages V according to FIG. 8 for door leaves T1 and T2, which are not only of different widths but also of different thicknesses.
  • the reinforcements 9 and 9 'of different widths are attached between the differently spaced folding groove pairs 8.
  • the packaging material or the packaging according to FIGS. 5, 7 and 8 can also be provided with further reinforcements in order to create suitable packaging for more than two differently sized door leaves with a basic shape.
  • Fig. 9 shows a packaging blank Z, in which each reinforcement 9 'is so wide that it extends over several pairs of folding grooves 8, 8' and 8 ''.
  • the folding grooves may also be formed in the reinforcement 9 ′′.
  • the reinforcement covers the strip-shaped surface area between the folding grooves.
  • the reinforcement slightly beyond the folding grooves (indicated by dashed lines in FIG. 12 at 9 ′′).
  • the reinforcement can only extend over a portion of the strip-shaped surface area on the corrugated side.
  • FIG. 10 illustrates a section through the packaging material from FIG. 1 or FIG. 9 in the plane X-X.
  • the associated FIGS. 11A, B and C illustrate sections in the plane XI-XI of FIG. 10 for different design variants.
  • the one-sided corrugated cardboard W according to FIG. 10 consists of a flat layer D onto which a corrugated layer K is laminated.
  • the one-sided corrugated cardboard W is produced in a corrugated cardboard machine, the direction of production in FIG. 10 being from left to right and the crests of the corrugations 6 denoted by 6 ′ running perpendicular to the plane of the drawing.
  • the flat reinforcement 9 is glued onto the corrugated side 5 of the one-sided corrugated cardboard W, expediently in areas 21 on the corrugated crests 6 '.
  • the reinforcement 9 is a flat strip that covers the strip-shaped surface area between a pair of folding grooves 8.
  • the folding grooves 8 are formed by conventional creasing tools either during the manufacture of the single-sided corrugated cardboard or later during the formation of the cut, specifically in the direction of production of the single-sided corrugated cardboard, ie perpendicular to the corrugated combs 6 '.
  • the folding grooves 8 can be formed from the corrugated side 5 and / or from the side of the flat layer D.
  • the reinforcement 9 is shown somewhat thicker than the layers D, K; but it can also be the same thickness as the layers or thinner.
  • the reinforcement consists of paper or cardboard, preferably the same paper as the layers D, K.
  • the reinforcement 9 serves as a carrier for a coating which, for example, foam, rubber, plastic, polystyrene, fleece or the like.
  • the reinforcement 9, 9 ', 9''could be provided with an imprint 23. If the corrugated side 5 faces outwards, the reinforcement is provided then an advertising, decorative, identifying or indicative effect.
  • the section of FIG. 11B belongs to the embodiment according to FIG. 9, in which the reinforcement 9 ′′ extends on both sides to a limited extent somewhat beyond the folding grooves 8 and is also grooved.
