Abstract

Cardboard box comprises inner flaps (I1, I2) with protruding tongues (Z1, Z2) with insertion bevels (E) on their edges facing away from the folding lines. The tongues of the inner flaps complement the tongues of an opposite-lying inner tongue. An independent claim is also included for a blank made from full cardboard for the above cardboard box.

Description

The The invention relates to a carton for article groups such as bottles or the like. According to the preamble of claim 1 and a blank according to claim 2.

For all-round packaging of article groups such as bottles, cans or the like are provided with fold lines blanks of cardboard according to the 1 in DE 40 18 140 C1 or the 4 and 5 in EP 0 849 176 B1 used, in the flat state, a group of articles pushed onto a bottom portion and subsequently folded up the side surfaces around their common to the bottom portion folding lines in a vertical position, then folded with a fold line on a side surface hinged lid surface in a horizontal position and then with a glue flap on the opposite side surface is glued. Subsequently or partly at the same time, inner flaps hinged on fold lines and outer flaps hinged on the bottom section or the lid surface are also wrapped and glued at 90 ° to the article group on the side surfaces so that a wrap-around packaging is formed which is generally closed on all sides ,

These The type of packaging is widespread and can be blended with blanks Corrugated board well in the manner previously described with the known Machine processing even at high power. Problematic By contrast, the processing of blanks from solid board. The im Compared to corrugated cardboard much thinner walled material has none comparable inherent stability and caused thereby inaccuracies in the molding and bonding a folded carton.

So must, for example, when gluing the lid surface with the associated adhesive flap guaranteed be that the terminal edge of the lid surface to the fold line of the adhesive flap on its side surface parallel and flush runs. To this parallelism to ensure even with solid board material, so far had Gluing the lid surface on the adhesive flap in the inside of the box a metal sheet as a counterpart or support be used. The problem here is the fact that the Sheet metal is enclosed in the box and the distance between Bottle top and the carton cover surface is normally zero. This afterwards required removal of the sheet when passing through the machine slows down the carton or deforms it. This sheet needs to be handled cantilevered and is therefore unstable. For several Formats in one machine the sheets are reproducibly changed, which is undesirable Effort is connected.

The Gluing the lower outer plates with The underlying inner plates is largely in the bottom area uncritical, because here is sufficient support by behind the Inner straps standing bottle hulls is given to the outer straps to achieve a good adhesive bond against the inner plates press to be able to. More difficult is the same task with the upper outer plates, because here, as a result of the rejuvenated, one smaller outer diameter having bottlenecks a support or a counterhold behind the inner plates is missing and the inner plates because of their instability are not suitable when pressing the outer plates a sufficiently large back pressure build. A perfect gluing is therefore difficult too Realize, because the back pressure arises only by the bending stiffness the inner straps, which is only slight with solid board material.

Of the Invention is therefore based on the object, a carton and a Cut to size Specify full board by an accurate shaping and good bonding can be produced in a packaging machine.

Is solved the task concerning the outer carton by the characterizing part of the claim 1 and the blank relating to the characterizing part of the claim Second

Thereby, that the inner tabs according to the invention now at their embarked State facing edges have protruding tongues with insertion bevels, can now between these edges two adjacent inner plates made a resilient connection For example, put the tongues behind a left inner tab the inner surface the opposite right inner flap flat come to rest and vice versa the tongues of the right inner flap on the outside the left inner flap resiliently rest, so that the free edges of the two mutually facing inner straps resiliently through the toothed positive connection of the tongues are connected and thereby advantageously when pressurized from the outside via the outer plates by the increased stability of the coupled Inner straps a greater back pressure to build up. At the Glueing the pressed against the inner plates (upper) outer straps thus creates a better contrast, only by the invention with tongues provided inner straps. Thus, a stable, resilient gluing possible.

In addition, the carton aligns automatically during the folding process and maintains its (rectangular) shape. It can neither a trapezoidal shape nor a parallelogram arise because the inner tabs aufwei aufwei with their insertion send tongues also against the inner edge of the tabs against each support and stiffen the tubular part of the carton, because a displacement of the edges is prevented longitudinally to each other by the adjacent approximately joint-free adjacent or adjacent tongues.

At the Wrapping, closing and gluing the lid, it is no longer necessary to carton with a separate counterholder from the inside to support. This is done by the now sufficient stiffening by means of the toothed inner plates, the before the folding and pressing the lid on the adhesive flap smashed and over her Tongues form-fitting can be connected.

following become preferred embodiments explained with reference to the figures. It shows:

1 two flat folding carton blanks with differently shaped tongues

2 one from a Faltkartonzuschnitt after 1 shaped carton.

In 1 above is a flat lying blank made of cardboard to form a well-closed cartons for beverage bottles or the like. Vessels shown. It consists of several surface sections, which adjoin one another at fold lines. These are seen in detail from left to right, a cover surface D, a side surface S1, a bottom portion B, a side surface S2 and a glue flap K. On the lid surface D are on both sides in each case upper outer flaps Ao; in the same way at the bottom portion B lower outer plates Au.

On the side surfaces S1 and S2 are located on both sides arranged inner flaps I1 and I2. These inner tabs have tongues Z1 or Z2 projecting beyond the edges R that project outwardly from the side edges S1 and S2, respectively, and having lateral insertion bevels E. The tongues Z1 of I1 are laterally offset to the tongues Z2 of I2 so that they are positioned in the finished folded state of the inner flaps I1 and I2 a folded carton immediately adjacent to each other almost without spacing along the outer edges of the inner flaps and almost abut each other. While the edges of a folded-in inner flap I1 and I2 face each other abruptly, the tongues Z1 bear the edge of I2 for example on the inside and the tongues Z2 the edge of I1 on the outside. Thereby, the mutually facing edges of the two inner flaps I1 and I2 are toothed and resiliently coupled via the flexurally elastic, pairs complementary co-operating tongues Z1 and Z2, when both side surfaces S1 and S2 unfolded and the inner flaps I1 and I2 are turned inwards. This situation is from the pictures of 2 recognizable, the lower figure shows a detail in an enlarged view.

The lower picture in 1 differs only by another geometry of the tongues. Deviating from the tongue embodiments shown, a triangular tongue formation with outwardly directed tip would also be conceivable. These tongues should be present at least at the areas of the inner flaps associated with the upper outer flaps.
