Description

TECHNICAL AREA

The present invention relates to a folding blank, in particular a one-piece, flat-lying folding blank of corrugated cardboard, or similar pulp-based packaging materials, as well as a foldable from a folding blank transport box, for example, for external packaging of general cargo such as bottles, cans or other liquid containers.

TECHNICAL BACKGROUND OF THE INVENTION

Lockable glass or plastic containers for storage and storage of liquids such as bottles are nowadays usually packaged as containers in closed folding cartons, the lid and / or bottoms are then optionally glued for transport. The individual containers can be separated by partitions inside the box to increase the mechanical stability and the resistance to breakage during transport. In such folding cartons, such as in the DE 10 2012 010 853 A1 disclosed, however, the packaged bottles are no longer visible from the outside.

On the other hand, display cartons are semi-open corrugated cardboard packaging in which goods are at least partially visible from the outside. This increases the marketing value for retailers, as they can be presented more aesthetically pleasing to the customer. Such display boxes, such as from the DE 20 2005 017 354 U1 However, for container transport, they offer less mechanical stability and thus an increased risk of breakage for fragile containers, such as bottles during transport.

There is therefore a need for possibilities for the production of transport cartons, which enable an efficient production process from a one-piece folding blank, have a high mechanical transport stability and make visible the goods to be transported in the transport carton for marketing purposes to the outside.

SUMMARY OF THE INVENTION

An essential idea of the invention is to use a one-piece folding blank, for example made of cardboard or corrugated cardboard with a front, are introduced into the narrow, running diagonally to a front edge creasing cutouts in a predefined distance. Between each two adjacent cutouts, parallel vertical crease lines are formed, so that the material webs, for example z-shaped, extending substantially diagonally between the adjacent cutouts can be folded along the parallel vertical crease lines. These folded material webs then form partitions of a compartment which projects into the interior of the folding blank folded into a transport carton for receiving transported goods.

Through the cutouts and the particular z-shaped material web folding insertion pockets are formed in the interior of the transport carton, the material webs equally form inner back walls and partitions of the Gefaches. Characterized in that inner rear walls and partitions of the Gefaches are formed by inwardly folded portion of the front side blank panel, the transport carton in the folded state on its front side a plurality of openings through which stored in the pockets transport goods inside the transport carton can be seen from the outside.

At the same time, the folding fold from the one-piece folding blank ensures high mechanical stability against distortion, shear loading or pressure. Furthermore, the inner compartment provides improved protection against tilting of the shipping carton itself and / or the transport goods within the transport carton. Furthermore, such transport cartons are very easy to produce because they can be folded without further passport tools from a single folding blank. In addition, the appropriate folding or folding of the folding blank a transport carton is formed with integrated compartment, for which no further deposits such as separate carding mats are necessary.

DETAILED DESCRIPTION OF EMBODIMENTS

The folding blanks shown below are each in one piece, that is, they are made of a contiguous piece of blank material by cutting outer edges and forming recesses in the interior of the blank material. The blank material can be, for example, corrugated board of different wave type (A, B, C, D, E, F, G, N wave or combinations thereof), cardboard or similar pulp-based materials such as paper composites with or without plastic coating include.

Crease lines in the sense of the present invention are all pre-embossed desired fold lines or creasing lines in the blank material, along which a bend is provided in the blank material for later three-dimensional production of a transport carton. Cutouts for the purposes of the present invention are in this case cut, punched or otherwise introduced into the blank material openings which are completely surrounded in the Faltzuschnittebene blank material. In particular, cutouts within the meaning of the present invention are narrow, elongated apertures of about 1 millimeter to 2 centimeters in width, which may extend across an aperture slot of 1 centimeter to several tens of centimeters. Such cutouts can be formed by punching the blank material and have at the beginning and end points pointed or rounded tapered punching ends.

1 shows a schematic representation of an unfolded folding blank Z in the plan view of the Faltzuschnittsebene. The illustrated folding blank Z is generally flat. The outer edges are each cut edges, from which the folding blank Z is cut from a larger layer of blank material - the inner edges shown are generally each crease lines or score lines along which a subsequent buckling of the folding blank Z is provided.

The folding blank Z includes a front F, which in the example of 1 rectangular with two side edges (in the 1 left and right), a bottom edge (in the 1 below) and a top edge (in the 1 above) is shown. A first end side S1 is hinged on the front side F via the first side edge, and a second end side S2 is articulated via the second side edge opposite the first side edge. The two end faces S1, S2 terminate flush with the front side F at the bottom edge and upper edge. The two end faces S1, S2 also have a rectangular shape and are congruent due to production, so that a cuboid transport carton can be formed from the folding blank Z.

A rear side R is articulated via a third side edge opposite the second side edge on the second end side S2. The back R terminates flush with the bottom edge and top edge respectively with the front side F and the two end faces S1, S2. The rear side is congruent with the front side F for producing a cuboid transport carton from the folding blank Z.

At the rear side R, a front side adhesive pocket S3 is articulated at a fourth side edge opposite the third side edge. In the folded state, the outer side edge of the first end face S1 and the fourth side edge of the rear face R encounter one another, so that the front side adhesive tab S3 at least partially overlaps the first end face S1. The overlapping region can be used, for example, for bonding the front side adhesive tab S3 to the first end side S1, in order to define a mechanically stable cuboidal interior of the transport carton.

At the bottom edges of the front side F, the two end faces S1, S2 and the back R are hinged bottom tabs: First bottom flaps B1 and B2 are hinged to the bottom edges of the two end faces S1, S2, second bottom flaps B3 and B4 are at the bottom edges of the front F and the rear R hinged. The bottom flaps B1, B2, B3 and B4 form the bottom of the transport carton in the folded state of the folding blank Z. For stabilization, adhesive flags B5 and B6 for bonding the second bottom flaps B3 and B4 to the first bottom flaps B1 and B2 can be hinged to the second bottom flaps B3 and B4, respectively. In this case, the second bottom flaps B3 and B4 can be made trapezoidal, and the adhesive flags B5 and B6 may be pivoted to the leg edges of the trapezium of the bottom flaps B3 and B4. On the first bottom flaps B1 and B2 paint exemptions can then be formed in the region of the adhesive bond.

In addition, it is possible that in each case on the second bottom flaps B3 and B4 each plugs B7 and B8 are pivotally hinged to each other for plugging connection of the second bottom flaps B3, B4. In the case of trapezoidal second bottom flaps B3 and B4, these flaps B7 and B8 can be articulated on the side edge opposite the base of the trapezoid. One of the terminal lugs B7 has a tongue issued by punching, which can be inserted into a punched-out insertion opening of the other pin B8 when folding. After the mating of the bottom flaps B1 to B6, the plug-in lugs B7 and B8 can then point parallel to one another into the interior of the transport carton, that is, from the bottom of the carton and, if necessary, be glued together. This can be formed inside the. Cartons dependent on the width of the terminal lugs B7 and B8 center partition, which can separate two rows of stacked in the transport box liquid containers at least in the lower area.

Optionally, for example if a transport box which can be closed from above is desired, cover lugs D1, D2 and D3 can be pivoted to the rear side R and the two end faces S1 and S2. The cover flaps D1 and D2 are folded when folding over the upwardly open, formed by the front side F, the end faces S1, S2 and the back R cuboid. The cover flap D3 is folded over the folded-in cover flaps D1 and D2 and optionally secured mechanically via an insertion tongue D4 against unwanted unfolding.

The cover flaps D1 and D2 can be provided, for example with round punched, which correspond to a folding of the cover flaps D1 and D2 on the box constituting the transport box in its vertical position above the bottom of the transport box with the pockets of the Gefaches. As a result, transported goods standing upright in the pockets of the compartment can protrude at their upper end through the cover lugs D1 and D2 and secured against tilting. For this purpose, the cover flaps D1 and D2 can also be offset offset inwards into the transport carton, so that the transport goods indeed protrude through the cutouts in the cover flaps D1 and D2, but not over the side walls of the transport carton.

Shown in 1 Furthermore, a front Gefacheabschnitt AF, in which targeted cutouts and fold lines in the front F and the second end face S2 are introduced in order to fold the folding blank Z inwardly angled in the transport carton integrated compartment for transportable in the transport box piece or packaged goods such as bottles, cans, plastic containers, smaller packaging boxes or other separable goods such as chocolate hollow bodies, candles or decorative items.

A distance can be left between the compartment section AF and the top edge of the front side F, which allows information to be affixed to the transport box above the compartment section AF, such as punches, imprints, labels, barcodes or the like, as to the content or the intended use of the transport cartons.

The folding blank Z may further optionally have a rear-side Gefacheabschnitt AR, which may be formed in principle similar to the Gefacheabschnitt AF. The Gefacheabschnitt AR runs over the back R and the front side Kleberasche S3 in an analogous manner to the Gefacheabschnitt AF. The Gefacheabschnitt AR forms during folding of the folding blank Z also from an inwardly angled in the transport carton integrated compartment, which adjoins the compartment formed by the Gefacheabschnitt AF.

2 shows an enlarged view of the Gefacheabschnitts AF in 1 in greater detail. The Gefacheabschnitt AR can be constructed analogously. The Gefacheabschnitt AF has two first cutouts C4, C5 in the form of S-shaped elongated slots, which are introduced into the front side F, and extend substantially obliquely at an angle to the bottom edge of the front side F. Slant here means that the angle along the cutouts C4 and C5 has a variable angle to the bottom edge of the front side F between 0 ° and 90 °. In the case of an S-shaped profile, the angle at the upper edge-side beginning of the cutouts C4 and C5 with respect to the bottom edge is initially 0 °, then increases continuously up to a certain maximum angle of approximately 60 ° and again decreases continuously in the end region of the cutouts C4 and C5 down to about 0 °. Alternatively, the cutouts C4 and C5 may have a Z-shaped course, in which the initial portion over a first length is at a constant angle of 0 °, adjacent to the start portion is a central portion which extends at a constant angle greater than 0 °, for example 60 °, over a second length, and connects an end portion to the central portion which is connected to a third portion Length again at a constant angle of 0 °. It is important here that the cutouts C4 and C5 generally run from top to bottom and form material webs or material bridges between the cutouts C4 and C5. The material webs or material bridges preferably have a constant width by the cutouts C4 and C5 follow the same angular course.

The number of first cutouts C4 and C5 is shown only as an example with two, any other number is also possible. The number of first cutouts C4 and C5 determines the number of pockets, which can be formed in the integrated compartment.

In the Gefacheabschnitt AF also a second cutout C3 is provided which extends in the same angular course as the first cutouts C4 and C5 from the second end face S2 on the second side edge in the front side F inside. In other words, the second cutout C3 forms an opening that extends beyond the second side edge.

Furthermore, a third cutout C1, C2 can be provided which runs parallel to the bottom edge of the front side F from the first side edge of the front side F over the second side edge into the second end side S2. The third cutout can be formed continuously or with one or more, if necessary uniformly spaced, desired separating tabs L1, which separates the third cutout into two lower cut-outs C1 and C2. In the flat state of the folding blank Z, the predetermined separating tabs L1 connect the front side areas below and above the third cutout for mechanical stabilization. Only when folding the desired separating tabs L1 can be severed to produce a continuous third section C1, C2.

The first, second and third cutouts C1 to C5 define a front side section F1, F2 which can be angled by suitable buckling into the interior of the finished folded transport carton. The front side section F1 forms the inner rear wall of the integrated compartment, while the connecting material webs or material bridges between the cutouts C3, C4 and C5 each form the transverse partitions of the compartment. The front side portion F3, which extends below the cutouts C3, C4 and C5, forms the lower outer wall of the compartment, so that packaged goods such as bottles can be accommodated between the inner rear wall F1, the transverse partition walls and the lower outer wall F3.

In the following, referring to the example view in FIG 3 shown how the fold lines in the region of the Gefacheabschnitts AF can be introduced into the folding blank Z in order to form the integrated compartment by folding the folding blank can. The example view in 3 shows a front section of a transport box P, which consists of a one-piece folding blank Z according to 1 and 2 has been folded.

The Gefacheabschnitt AF has for this purpose a first Gefacheknicklinie K1, which extends from the second cutout C3 in the direction of the upper edge of the second end face S2 parallel to the second side edge in the second end face S2. A second Gefekeknicklinie K3 runs from the first cutout C5 toward the upper edge of the front side F parallel to the first side edge in the front side F. The two Gefacheknicklinien K1 and K3 ensure that the front side section F1, F2 can be angled inwards front side portion F1 cut out by the cutouts C1 and C3 is inwardly folded along the first bin folding line K1, so that the front side portion F1 projects perpendicularly into the inside of the transport carton P from the second end side S2. The protruding length of the front side portion F1 is shortened again by kinking along the second Gefacheknicklinie K3, so that the part F2 of the front side portion abuts on the inside of the first end face S1. This part F2 of the front side portion can then be glued to the inside of the transport box P on the first end face S1 or otherwise positively connected.

To form the transverse partition walls projecting from the inner rear wall inside the transport carton P toward the front side F, third tine folding lines K5 and K7 formed between the second cutout C3 and the first cutouts C4, C5 become parallel to the first side edge in the front side F, and formed fourth Gefekeknicklinien K6 and K8, which are between the second cutout C3 and the first cutouts C4, C5 spaced and parallel to the third Gefacheknicklinien K5 and K7, respectively. By z-shaped bending of the material webs between the cutouts C3 and C4 or C4 and C5 at the third and fourth Gefacheknicklinien K5 to K8, the material webs may represent the transverse partitions. Although these transverse partitions do not extend completely from the upper edge to the bottom edge of the transport carton P, but offer sufficient mechanical stability for packaged in the integrated compartment packaged goods, such as a arranged in one of the pockets of the bin glass bottle in the central region of the transport box.

If the first, second and optionally third cutouts C1 to C5 each comprise narrow, elongate cutouts from the folding blank Z, the integrated, inwardly angled remains Compartments in the area of the compartment section AF mechanically sufficiently stable.

Also the Gefacheabschnitt AR on the back R can be formed in an analogous manner. For this purpose, fourth cutouts are introduced in the rear side R, which run obliquely at an angle to the bottom edge of the rear side R. In addition, a fifth cutout extends in the same angular course as the fourth from the front side adhesive pocket S3 over the fourth side edge into the rear side R. The adhesive lug L3, which on the front side adhesive tab S3 can be fitted into a tab opening L2 punched optionally along the Gefacheknicklinie K3, so that the Stirnseitenklebelasche S3 overlaps with the first end face S1 when gluing a maximum of two layers. The two inwardly facing front and rear side sections F1, which form the inner rear walls of the integrated compartments in the middle of the transport carton P, can also be glued back to back.

Different variants for the folding blank Z are also conceivable: While the third cutout C1, C2 defines an upper edge portion of the front F and back R, which serves as an outer wall for retaining upper parts of the packaged goods, such as bottle necks (see 3 ), can be completely dispensed with the third section C1, C2 and optionally the cover flaps D1 to D4. In this case, from the folding blank Z an upwardly open transport carton with integrated compartment can be created, which can be used, for example, mainly for display purposes. From such a transport box, the packaged goods can be easily removed from the Gefachetaschen up.

Furthermore, it is also possible to completely dispense with the rear compartment section AR. In this case, the folded transport carton P has only a display effect in the front side area, while the back side R is similar to that of an ordinary packaging carton.

If necessary, the bottom flaps B1 to B8 can also be held together by a different closure mechanism than a pluggable connection. For example, instead of the terminal lugs B7 and B8, in addition to the adhesive lanes B5 and B6, further adhesive lugs can be attached to the remaining limb edges of the trapezoidal base lugs B3 and B4.

The transport cartons P to be folded from the folding blanks Z shown and described are simple to manufacture since, apart from possibly some adhesive for the glued connection, no additional tools are necessary. Furthermore, an adaptation of different blank parts to each other is eliminated since the folding blank Z is already in one-piece or one-piece form.

The folding blanks Z offer the possibility of producing a mechanically stable transport carton P which has a display opening, from the goods packed in the transport carton P not only from the front F and back R, but also via the open corner from the second end faces S2 are visible to the outside. The marketing effect for such packaged goods is significantly improved, since the goods can be seen by customers looking at the transport carton at almost any angle.

In addition, the folding blanks Z allow a very efficient and sustainable production, since in the production of folding blanks Z very little waste material and thus very little waste material is obtained. In particular, the outwardly open display opening does not have to be cut out of the front side, so that no cardboard material is wasted for the production of the display opening.
