Definitions

  • the invention relates to a convertible packaging element with advantageous storage, reuse and disposal properties.
  • Packaging elements of the usual type are used to protect objects against damage from impacts or pressure from outside. If the objects do not have smooth outer surfaces, but also protruding parts such as feet, buttons, levers, hoes, etc., these packaging elements also have the task of protecting these protruding parts and of forming a package with flat outer surfaces for the object with irregular outer contours, so that the packaged items are easy to handle, put down in different positions or can also be stacked.
  • packaging elements that consist of one or more molded parts made of foam have become established today. These foams very often have a cellular structure, are very light and are cast as foam in a mold.
  • the molded part is placed on the object or the object is placed in the molded part and possibly both are provided with an outer packaging which, for example, also contains information about the packaged object such as brand, type, use, size, manufacturer, etc.
  • outer packaging often consists of a relatively thin-walled cardboard or a film.
  • packaging elements also have disadvantages of various kinds.
  • the manufacturing process itself requires a certain "know-how" and certain systems to master the handling of such materials.
  • This means that such packaging elements must be manufactured by specialists who also want to produce large quantities of such packaging elements, although not always with the same shape.
  • packaging elements must be stored and transported. Because of the complicated shapes and because the design is as one-piece as possible, such packaging elements take up a lot of space. This is mainly due to the cavities that three-dimensional structures can enclose.
  • the foam used is light and thermally well insulating, but is not very strong. If you want to use it to pack fragile goods, you have to form thick-walled structures to achieve sufficient rigidity. This in turn leads to voluminous packaging that is no smaller when empty than when it is filled. If the packaging is then to be wrapped with a shrink film, for example, these loads must also be taken into account, which further increases the volume.
  • the invention as characterized in the claims, is therefore intended to solve the problem of creating a packaging element for packaging a mainly flat object which is particularly simple, volume-saving and environmentally friendly and which does not have the disadvantages mentioned.
  • the solution to this problem is preferably based on recyclable materials that are available in sheets or panels, such as Cardboard, corrugated cardboard and the like, but other materials can also be used, since the invention is largely independent of the material. But it is therefore particularly suitable for the use of environmentally compatible materials and, if wood is used, for example, it also has the option of recycling in a deposit system.
  • the packaging element typically has a carrier surface which approximately corresponds to the base surface of the object to be packaged, but projects beyond the sides thereof and thus forms side parts which can be folded back onto the carrier surface and protect the side surfaces of the object with their thickness. For protruding parts, openings can also be made in the carrier surface in which these parts are embedded.
  • a simple manufacturing method can be derived from this, which comprises a few steps, for example two, possibly three steps.
  • the material is cut out or punched out, any openings are also made, in this state it is flat and especially suitable for storage.
  • the side parts of the still flat structure are folded over in a next step, for which purpose, depending on the material, the material is first cut along a folding line, for example to a certain depth.
  • the cutting and / or punching out of the material can also be carried out together with the creasing or cutting along fold lines in a single operation.
  • the side parts are preferably releasably glued to the support surface.
  • a cavity is thus formed, into which the object can be placed in the packaging part and, for example, can be wrapped with the packaging unit with a shrink film.
  • the packaging element can be finished from a preliminary product by "flipping” or bending the side parts.
  • the packaging elements can be prepared by "folding” or bending back the side parts to save space for reuse or before disposal. The "flip-flap” movement thus elegantly converts the preliminary product into a finished product and back again.
  • this solution opens up a variety of possibilities when choosing the material from which the packaging element is made. It is preferred that the material can be cut and punched and has a certain elasticity so that it can also be bent. Particularly advantageous are materials that have a layered structure and already offer a kind of hinge that can be opened and closed. With such materials, certain layers can be cut through and other layers remain as a hinged hinge. A good example of this is corrugated cardboard, especially if it consists of several layers. If the selected material does not have this property, it can be given to the material by covering it with a layer of another material, so that this material can then act as a so-called "film hinge" for the side parts.
  • a preliminary or intermediate product can be created from the material, which consists in the material being cut or punched out in the desired shape and possibly being provided with the desired openings and incisions.
  • This intermediate product can be produced with relatively simple machines.
  • the intermediate product can be stored very well, since the intermediate products can simply be placed one on top of the other and do not form any gaps. This also significantly simplifies transportation.
  • the finished packaging element can then be produced very easily by hand or using very simple machines. This also means that tool costs are comparatively low. In any case, the whole process can be automated for large quantities of packaging.
  • the invention results in a space-saving, environmentally friendly and easily producible and transportable packaging element in every respect, which is not bound to complex shapes and which does not require high investments in machines and systems equally suitable for any number of items and that can already be produced efficiently in small numbers.
  • This is because existing materials can be used for production and only simple processes are used.
  • This results in an optimization of the properties, which is unknown with the usual highly specialized packaging methods, but which does not mean simply reactivating well-known steps, because the astonishing simplicity is also paired with technical sophistication, as is demonstrated, for example, by the skillful use of a film hinge leaves.
  • a particular advantage can also be seen in the fact that the production of the material used and the shaping or processing of the material are completely independent of one another.
  • FIG. 1 shows as a preliminary product for a packaging element for a picture frame, a part 1 cut out or punched out of a suitable material, for example from a flat, from a sheet or from a plate, on which a surface 3 is delimited by a dash-dotted line 2, which corresponds approximately to the area of an object that is mainly to be covered by this packaging element or that is to form a support surface for the object.
  • Dashed lines 4 indicate the location for partial cuts in the material, which are provided here on the back. If the corners, as indicated by the reference number 5, are chamfered at an angle of 45 degrees, side parts 6, 7, 8 and 9 can be folded back against the surface 3 and optionally glued there. Openings 10 give space for protruding parts such as chopping a picture frame.
  • Figure 2 shows a perspective view of a partially completed packaging element, here also for example for a picture frame.
  • a support part with the surface 3 as a support for the object and the already folded side parts 6, 7 and 8.
  • the side part 9 is only slightly angled so that one can see particularly well an incision 11 and a bridge 12 formed thereby, which also forms a film hinge.
  • An object 35 here contours of a picture frame, are indicated by dash-dotted lines.
  • the surface 3 can easily have a wide variety of shapes, as shown, for example, by the contours 13a and 13b drawn on one side. Corresponding alternative contours 13a and 13b can also be seen in FIG. 1. From this it can be seen that any contours of this type are created when part 1 is cut out.
  • the side parts 6, 7, 8 and 9 can also be provided with openings to accommodate protruding parts.
  • FIG. 3 shows, for example, a longitudinal section through a further embodiment of a packaging element according to the invention.
  • This has two folded side parts 14 and 15 connected in series, which are placed one on top of the other and thus result in a greater height above surface 3.
  • a resulting intermediate side part 16 can optionally be separated along a line 17 so that it does not protrude laterally.
  • the packaging element can also be supplemented by a cover 18, so that a closed volume is created for the object.
  • the separation is not continuous, because this must leave at least one cover layer 22 untouched.
  • the cover layer 22 namely forms bridges or hinges 23, 24 and 25.
  • the cover layer can be separated from a homogeneous material only in the area of the hinges and only by not completely pulling through the cut, or by the structure of the material , such as corrugated cardboard.
  • the cover layer 22 can, however, also consist of a different material than layers 26 and be applied beforehand to the layers 26 or a homogeneous material, for example by gluing.
  • the cover layer 22 can have specific properties such as toughness, elasticity, etc. which are important for the hinges.
  • the remaining material or the layers 26 can consist of a material with other properties, such as, for example, great flexural strength, deformability, good damping properties, good thermal insulation, etc. Taken together, a material can be created which has the desired variety of properties.
  • incisions 27 and 28 are to be made from both sides.
  • Bridges 29 and 30, which are assigned to opposite surfaces of part 1, also form in this way.
  • a first side part 33 can be folded around the bridge 29 and a second side part 34 around the bridge 30.
  • the folds take place in the same direction of rotation for the embodiment according to FIG. 3, the direction of rotation alternates in the present embodiment.
  • a coating with a suitable material must be carried out on both sides according to FIG. 4 for this embodiment. In this way, more than two side panels can easily be connected in series and folded down.
  • the outer contours 13a, 13b of part 1 and the openings 10 are punched out or cut.
  • the side parts 6, 7, 8, 9 are folded down and possibly fixed on the surface 3, for example by gluing.
  • an intermediate side part 17, if present, can also be partially separated.
  • the object is placed in the packaging element and possibly a cover 18 is attached and fastened, or a shrink film is shrunk on.
