Description

Description: Cardboard blank The invention relates to a cardboard blank to form a cardboard box open at its longitudinal ends.

Such a cardboard box is used, for example, as a carrier for bottles , Cans or bags that should be at least partially visible.

The invention is based on the object of a blank for a to create such a cardboard box with a one- or two-part bottom surface, the one Cardboard results, the longitudinal ends of which are at least partially closed by an end piece are.

At the same time, the end piece should be attached to the box in such a way that it at least as long as the box is filled with objects, not without further ado folds out, but a relatively secure closure of the envelope-like cardboard box Finally, the corner piece should be fastened in such a way that a stable corner connection is formed.

The tasks set are achieved according to the invention in that both sides of at least one fold line connecting the bottom surface with a side wall one over the edge of the blank rayender over one that extends the edge Fold line tabs connected to part of the side wall and part of the bottom surface is provided by an extension of the fold line between 5eitenwand and into an end piece that can be folded around the edge of the side wall and one around the Edge of the kodenfläche foldable closing surface is divided, and that the closing surface by a fold line connecting the bottom surface with the side wall from the point of intersection and the fold lines that extend perpendicular to this and extend the card, outgoing and with the extension of the fold line at an acute angle enclosing the weakening line is divided into two triangular or trapezoidal closing surface sections, the can be folded around this line of weakness.

The angle between the line of weakness and is advantageously the extension of the fold line 45 0.

An aura design of the invention is that the bottom surface from two overlapping and in a known manner by means of tabs or the like

connectable parts.

The invention also relates to a carton made from the inventive Cut formed si *. It is characterized in that the side walls around the Fold lines are folded perpendicularly with respect to the bottom surface that the end piece is around the fold line shared with the side wall is folded at right angles and with the membrane surface also includes a right angle and that the closing flap sections folded around the common line of weakness in this way are placed on the floor surface that the Schuiächunqslinie with the Faalz -linie between the diode surface and the side wall is common.

The invention is particularly useful and simple Manageable shape that guarantees a strong corner connection Gussets formed from the closing surface sections and resting on the bottom surface can be knocked in loosely or firmly attached to the floor surface.

By the fact that the container to be received in the carton rest on the gussets, they are kept in their position even if they are only loosely wrapped.

In the drawing, the invention is explained in more detail, for example, namely: Fig. 1: a perspective view of a carton according to the invention 2: an enlarged, exploded sectional view along the line 2-2 in Fig. 1 3: a greatly enlarged detail of a top view to one of the corners to be formed from the blank and FIG. 4 / a partially enlarged Sectional view along the line 2-2 in FIG. 1 to show how a container is in a cardboard box can be accommodated.

Fig. 1 shows a generally designated 10 carton consisting of a generally rectangular blank made of cardboard or similar foldable material is. Although the blank 11 (FIG. 3) is not shown in its entirety, be it but understood to mean that the blank 11 apart from the part shown in FIG common build is. When the blank is unfolded, it forms a box with it a top 12, a pair of side walls 13, 14, an outer bottom surface 15 and an inner bottom surface 16.

The bottom surfaces 15, 16 are provided with conventional tab connections 17 connected to one another, which consist of a lot of the same openings 18 in the inner Bottom surface 16 and a plurality of cutouts from the material of the bottom surface 15 primary tab strip 20 and secondary tab strip 21 exist. The tab strips 20, 21 are connected to the openings 18 as clearly shown in FIG.

In order to facilitate the folding of the blank 11 into a cardboard box 10, the blank has a number of transverse fold lines, e.g. B. Fold lines 22,23, which connect the top 12 to the side walls 13,14.

In addition, fold lines 24, 25 ~ connect the respective side walls 13, 14 with the inner or outer bottom surface 15, 16 En of the interface of each side wall and floor area there is an identical corner connection. There is four such corner connections 31 to 34 as FIG. 1 shows.

Since the corner connections 31 to 34 are identical, the following only the corner connection 34 described in more detail, which is useful for understanding the entire invention is sufficient.

The corner joint 34 is best understood when one begins Fig. 3 viewed 5 which shows part of the side wall 14, the durch.die fold line 24 is connected to the inner bottom surface 16, which also has a fold line 35 parallel to the fold line 24. An end piece 36 is by a curved edge 37 bounded and connected to the side wall 14 by a fold line 38 which is perpendicular on fold line 24 and fold line 40, which is practically an extension the fold line 24 represents. However, the fold line 40 also serves as the end piece 36 to connect with painting means for the end piece, which is designed as a closing surface 41 and are generally rectangular in shape. The closing surface 41 is through the fold line 40, d. H. an extension of the fold line 24, an extension 42 the longitudinal fold line 38 and edges 43,44 delimited generally. perpendicular to each other stand. The closing surface 41 is also a pair of closing surface sections 45, 46 divided by a line of weakness 47 have a generally triangular shape. The fold lines 40, 42 and 47 have a common point of intersection, dsr in general is denoted by 50. The angle AyS between the fold lines 42, 47 on the one hand and 40.47. on the other hand are identical and are generally 45 °. If the carton 10 has been put together in the manner described below, the Fold line extensions 40, 42 exactly one above the other, parallel to the floor surface and perpendicular to the side wall 14 and its fold line 38 The corner connection 34 as well the remaining corner joints 31 to 33 are only made by folding the end face 36 and the closing surface 41 along the fold line 38 and its bracket 41 in brought the position shown in FIG. This creates the end piece 36 and the closing surface 41 brought perpendicular to the side wall 14 and to the bottom surface 16. Then the bottom surface 16 wiid in its end position perpendicular to the side surface 14 folded around the fold line 24 by a downward fold. Be at the same time with it the closing surface portions 45,46 folded to one another so that they one after form an outwardly opening gusset that closes itself and afterwards into the position that it is shown in Fig. 1 with the fold lines 40, 42 generally parallel one above the other and lie perpendicular to side wall 14, while the fold line or line of weakness 47 is now approximately 45 ° to the side wall 14. The closing surface cutouts are in this position 45, 46 generally parallel to one another with the closing surface portion 45 between the closing surface portion 46 and the inner bottom surface 16 is included.

When items to be packed have been placed in the box, is this by means of the openings 18 and the tab strips 2O, -21 in the usual way Way closed. It should be noted, however, that when the box 10 is fully erected (Fig. 1) an object A, only one of which is shown (Fig. 4) with its bottom surface rests overhanging on the closing surface 41, which is now closed with a gusset, and thereby the sleeping surface 41 between the bottom surfaces of the object A the bottom surface 16 includes.

In this way the objects are prevented from moving axially move out of the box 11, the end pieces 36 also contributing to this to exclude unintentional unfolding of the closing surface 41 if it is easy is arranged in the manner described before
