Description

The invention relates to a shipping container for receiving cuboid rigid packaged goods, comprising a single corrugated cardboard blank comprising two pairs of in side by means of first fold lines hinged side wall panels, in the state closed from the corrugated board with four longitudinal sides and two end faces erected packaging in pairs in parallel position the cuboid shape of the packaged goods forming the longitudinal sides, facing each other, as well as end wall panels which are hinged to blank panels by means of fold lines and in the erected packaging state in parallel position corresponding to the cuboid shape of the packaged goods, forming the front sides facing each other.

Out GB 176 936 A a generic shipping container is known, further comprising the following features: The end faces comprise edge fields, which are hinged with fold lines in each case to an associated side wall panel; at least two edge fields of each end face are articulated with fold lines the end wall associated with end wall panels; in the erect packaging state come at least two Stim wall panels double-layered to each other; By means of the fringe fields, a retracted crumple zone edge acting as impact protection is formed on the front side of the packaging. Number, arrangement and articulation of the fields according to GB 176 936 A known packaging require a construction such that the crumple edge is divided into sections, each formed by a clutter wall framed edge field. Butt fields that form attachment tabs are hinged to sidewall panels that are free of endwall panels. Cleared corner areas are weakened despite a considerable use of material, which is due to all-sided three-ply edge fields and additional fastening straps.

There are also known corrugated board packaging, which are erected from a corrugated cardboard to pack also cuboid stiff packaged goods. To padding additional separate padding means or elements in the Packaging inserted or intended as an inner packaging packaging is additionally housed in an outer packaging.

The invention is based on the objectives to provide a shipping corrugated packaging for lumpy, cuboid stiff packaged, which build very simple and with little use of materials and yet should form a particularly effective edge and corner protection. The corrugated board material should be used effectively such that reinforced padding or protection zone is formed on particularly sensitive end faces of the cuboid rigid packaging material. The overall packaging, namely the cuboid rigid packaged goods to be packaged together with the corrugated shipping material, should be available for shipment in an easily manageable unit. In particular, the desired shipping or transport packaging for parcel shipping should offer advantages. It should in particular plate-like parts that are layered into a block-shaped block record and a especially for front and corner areas to ensure transport that prevents damage.

The objectives of the invention are achieved in conjunction with the features mentioned above in that the end faces of the packaging comprise fringe fields, which are articulated by means of second fold lines in series to each other and by means of third fold lines respectively to an associated side wall panel, and that at least two edge fields each end face means Four folding lines are hinged to the end face associated end wall panels, in the erected packaging state at least two end wall panels abut each other and the edge fields abut the side wall panels hinging them, in which position the side wall panels together with the end wall panels a front side retracted on the packaging, acting as impact protection Form crumple edge.

With the measures according to the invention to achieve the desired benefits. In particular, the retracted crumple zone edge which acts as impact protection is formed on two opposite end faces of cuboid rigid packaged goods. It is an edge that protrudes from the front, leaving a cavity between the supernatant, in which the edge material can dodge to absorb shock. As a result, impact force is kept away from the front edges and corners of the packaged goods. An integrated buffer or crumple zone is obtained. This succeeds according to the invention with a single corrugated board cut, which is multi-layered in the front edge and corner area and there produces the desired protective function. The inventive, formed from a single corrugated cardboard shipping packaging ensures a body-tight investment inner sidewall fields and end wall panels on the packaged, the corrugated cardboard blank is wrapped in the packaged and is held with per se known clamping means in the packaging material receiving packaging condition.

The crumple zone edge in the state of the erected packaging is advantageously double-walled. This means that the edge, which encloses a kind of unilateral hollow wall, which is completely closed on the inside and open on the outside, runs without interruption with only one seam double / double layer.

Preferably, in the state of the erected packaging, each end face with at least two Stirnwandfeldern full-surface two-ply, so that not only the crumple zone edge is two-ply, but also the bounded by the edge end face of the packaging end face. An end face may also be formed with three and more adjacent end wall panels, which are hinged to associated edge panels.

An advantageous embodiment is that are hinged to at least one said end wall panel end wall tabs by means of the fourth fold lines transversely directed fifth fold lines, wherein the end wall tabs are articulated on opposite edges of the end wall panel or the end wall panels. Advantageously, such end wall brackets in the condition of the erected packaging form a border enclosing the cuboid packaged article. In particular, the front wall panel which articulates the end wall flaps comes to rest on the inside of the packaging. Thus, the edge protection is further improved by at least one end wall panel is extended with fold-in or folded tabs in the longitudinal side areas.

According to the invention, the corrugated cardboard blank is provided in a particularly simple manner in that a first side wall panel forms a base panel with longitudinal edges, to which respective second side panel panels are hinged by means of associated fold lines, and third side panel panels, in the condition of the package with flat corrugated cardboard blank in the outside thereof, to the second Side wall panels are articulated by means of associated folding lines. The blank design can be provided particularly simply by the fact that the packaging, viewed in the state of its flat-lying corrugated cardboard blank, is formed symmetrically with its side wall panels and their edge panels with respect to a longitudinal center line of the base panel. A particularly simple design is also achieved in that the packaging, viewed in the state of its flat-lying corrugated cardboard blank, is formed symmetrically with its side wall panels, edge fields and end wall panels with respect to a said longitudinal center line perpendicularly directed transverse center line of the base field.

The packaging according to the invention can be conveniently adapted to flat cuboid packaged goods. Advantageously, then have the sidewall fields of the two side wall panel pairs in pairs different field widths between the articulating first fold lines, and the end wall panels are articulated via the associated edge fields to the wider side wall panels.

The use of corrugated cardboard can advantageously be reduced in particular in that the corrugated cardboard cut is formed by double-sided corrugated corrugated cardboard. Advantageously, you can provide a fine wave. A particularly thin packaging casing is obtained, which extends over the longitudinal sides, but due to the above-mentioned field arrangement and multiple layers on the end faces, the said padding and the crumple zone region are achieved.

The packaging according to the invention forms a particularly satisfactory packaging unit in particular in the state with eingelteem, wrapped packaging material, which can be made up as a single packaging in large quantities, kept in stock and distributed according to logistics shipping requirements. The packaging is therefore particularly provided for the manufacture of shipping units, which are commissioned and sold in large numbers, for example via the Internet.

The packaging in the form of the packaging unit is characterized in that the package in its erected state comprises the cuboid rigid packaged goods, wherein a play-free fit is formed with side wall panels and end wall panels, against which the packaged product is applied, and that at each crumple forming a cavity Edge of the packaging at its two end faces closing the clamping closure, advantageously a strap, a front-clamping ring od. Like. Attached and closed under closing tension. This achieves a kind of constriction of the crumple zone edge by means of the tension lock, ie a slight compression of the crumple zone edge, so that the ends of the packaged goods are relieved of closing force and, moreover, a particularly strong integration of the packaged goods between the front sides is achieved. At least one longitudinal location of the shipping container, this can be closed with at least one other clamping closure, in particular a clamping band or ring, wherein the longitudinal sides of the associated circumferential location the packaging in the region of the packaged goods are subjected to closing voltage.

It has been found that the shipping packaging according to the invention enclosing the cuboid packaged article forms a particularly advantageous shipping unit if the cuboid rigid packaged article is formed by a plurality of laminated laminate plates which form in this layering an elongated cuboidal packaging block to which the internal dimensions of the erected corrugated cardboard blank adapted for producing the play-free fit. In particular, the laminate panels are a plurality of identical laminate floorboards whose front ends are particularly sensitive and prone to springs and / or grooves formed there.

In Fig.1 a packaging 1 according to the invention in the state with flat-lying corrugated cardboard blank 2 is shown. In the exemplary embodiment, the corrugated cardboard blank 2 should consist of single-walled, double-sided corrugated board. The corrugated cardboard blank 2 comprises side wall panels 21, 22, edge panels 4, end wall panels 23 and end wall panels 24. The panels are at least substantially rechteckförnüg and articulated by folding lines 3 to each other.

A sidewall panel 21, 211 forms a central, elongated rectangular basic field with length L. At this, are, with the same length, via first fold lines 31 side edge panels 22, 221; 22, 222 articulated. On the side wall panels 221, 222 are on the outside in the corrugated cardboard blank 2, over the length L side wall panels 21,212 and 21, 213 hinged by means of fold lines 31. The end wall panel 211 and the end wall panel 212 form a side wall panel pair 210. The shaft W of the corrugated cardboard blank 2 runs parallel to the first folding lines 31.

On the side wall panels 21, 22 are each continuously through the field width on both sides of said edge panels 4 hinged by means of third fold lines 33. The edge panels 4, which have the same width, are hinged together in series by means of second fold lines 32, each extending in extension of the first fold lines 31. It can be seen that in each case an edge field 41, 42 and 43 is hinged to the wide edges of the sidewall fields. Furthermore, an end wall panel 23, 231 is hinged to each edge panel 41 which is hinged to the side wall panel 211 by means of the fourth fold line 34, namely on the outside in the corrugated cardboard blank 2 over a length which is equal to the width of the side wall panel 211. The end wall panels 231 form a pair of end wall panels 230 that extend over the Edge fields 41 are hinged to the side wall panel 211. The aforementioned end wall tabs 24 are hinged by means of fifth fold lines 35, which extend in extension of the second fold lines 32, to each end wall panel 231.

Further, the corrugated cardboard blank 2 comprises another pair of endwall panels 232. The endwall panels 232 are hinged over the wall panels 43 only to the sidewall panel 212, but not to the sidewall panel 213, although e.g. Such a design is also possible.

How out Fig. 1 As can be seen, the packaging 1 or its corrugated cardboard blank 2 is symmetrically formed with the side wall panels 21, 22 and the edge panels 41, 42, 43 with respect to an imaginary longitudinal center line 101 of the side wall panel 211. The flat-lying corrugated cardboard blank 2 is also formed symmetrically with respect to a transverse to the longitudinal center line of the side wall panel 211 transverse center line 102.

In the Fig. 1 shown cutting surface should be the inner surface of the package 1. On this inner surface, the first, second and third fold lines 31, 32 and 33 are preferably formed as folding lines inwardly folding. The fifth fold lines 35 expediently preferably fold inward, while the fourth fold lines 34 for promoting the folding as outward, ie for in Fig. 1 Rear surface fold-fold lines are formed. The second fold lines 32 may be formed as a double score line to favor the folding described below.

The side wall panels 21, 22 have between the hinging first fold lines 31 different width. The width of the sidewall panels 22 of the pair 220 is less than the width of the other sidewall panels 211, 212 and 213. For example, the width of the sidewall panels 211, 212, 213 is two to three times greater than the width of the sidewall panels 221, 222.

In Fig. 2 and 3 is the shipping container 1, formed from the corrugated cardboard blank 2 according to Fig. 1 , in the erected state, this shipping container 1 is filled with cuboid rigid packaging material 9 and the component of the package also three tension locks 7 in the form of two outer clamping rings 71 and an inner clamping ring 72 belong, with which the erected corrugated cardboard blank 2 is clamped tightly against the unyielding packaging material 9.

The field or internal dimensions with which the corrugated cardboard blank 2 comes to rest against the packaged goods 9 are adapted to the latter. One recognizes Fig. 2 and 4 in that the packaged item 9 sits in a play-free fit between the sidewall panels 21 and the end wall panels 23.

In the Fig. 2 and 3 illustrated shipping container 1 in the form of packing and clamping unit is formed z. B. in that the packaged 9 is placed on the inner side wall panel 211 of the flat corrugated cardboard blank 2 and then the raising by applying the side wall panels 21,22 and the end wall panels 23 takes place on the packaged 9. Appropriately, the procedure is that initially a side wall panel 221 erected by 90 ° and the side wall panel 212 is turned by 90 °, so that the two side wall panels 221, 212 come to the packaged 9 flat to the plant. Similarly, then the other side wall panel 222 and the hinged side wall panel 213 are folded over the inwardly folding fold lines 31 by 90 °, the side wall panel 222 comes directly to the plant to the packaged 9, while the side wall panel 213 comes to rest against the side wall panel 212 and this covers, as this particular in Fig. 3 and 4 you can see. It can be seen that the side wall panels 211, 212 and 221, 222 in pairs form the longitudinal sides 11, 12 of the erected packaging 1.

In the course of erecting the open end faces of the package 1 are closed by the edge panels 4 are folded over by 180 ° to the third fold lines 33 inside, so that they come to the side wall panels 21, 22 to the plant. It can be seen that a front edge in the form of a double-layer crumple edge 5 is formed, which forms a shock absorbing distance zone which protrudes from the packaged 9. The third fold lines 33 are designed as double-folding score lines 330, so that the crumple zone edge 5 receives a line thickness or width R corresponding to the line spacing of the fold double lines 330, which further enhances the end-side impact resistance or the compression resistance.

It is also essential that the end wall panels 231 are erected by 90 ° around the outwardly folding fold lines 34 with respect to the edge panel 41 and brought into abutment against the end face of the packaged product 9. In this case, the end wall tabs 24 are also turned inwards by 90 ° with respect to the end wall panel 231, so that the end wall panel 231 and the end wall tabs 24 articulated thereto form an end-side enclosure 6 on and for the packaged product 9. The enclosure 6 of the erected, packed package 1 is made in particular Fig. 4 seen.

After erecting the end wall panel 231, the front wall panel 232 is erected at each end face by 90 ° with respect to the edge panel 43, so that it comes to bear against the end wall panel 231 flatly. At each end face the end wall panels 231, 232, in the embodiment over the entire surface, a double-layered end wall or end face 13. The end wall panels 231 and the end wall panels 232 are located on the packaged 9 or on the erected shipping container 1 in pairs and parallel. Said dimensioning for forming the skirt 6 is such that the length of the packaged product 9 is equal to or equal to the dimension L-2R.

As in particular from Fig. 3 and 4 As can be seen, the flat adjacent side wall panels 212,213 cause the crumple zone edge 5 is double-walled on one broader longitudinal side 11 of the package 1 double, the strength of the circumferential crumple zone edge 5 on this longitudinal side 11 is determined by the double edge width R. Otherwise, the peripheral crumple edge 5 has the edge width R.

How out Fig. 2 . 3 and 4 As can be seen, the shipping container 1 comprises in its erected state at its end faces in each case a tension lock 7. The tension lock 7 is formed by a tension band 71, which is tensioned by means of a buckle 70. The tension band 71 is annularly placed and stretched around a cavity area formed by the circumferential crumple zone edge 5. As a result, the packaged 9 remains free at its front ends of direct clamping voltage or strapping. With this type of closure in combination with the crumple zone edge 5, the ability of impact absorption at the end faces is increased.

How out Fig. 2 As can be seen, the package 1 comprises halfway along a further tension lock 7 in the form of a tension band 72, which forms a packaging material 9 and the longitudinal sides 11, 12 exciting enclosing strapping, which is closed with a buckle 70. The number of such buckles along the package 1 is applied in accordance with the dimension and weight of the package. The tension locks may also be designed in any other suitable manner in order to apply the erected corrugated cardboard blank 2 as an exciting sheath to the packaged goods 9.
