DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

In 1 and 2 there is shown a packaging carton marked 1, comprising a bottom 2 and four cavity walls 3 - 6 that stick up from him. The packaging carton is formed by a foldable molding that fits into 4 is shown in a flat, unfolded state, wherein the molded part is a lower part 7 , Wall assemblies 8th - 11 with inner 12 - 15 and outer 16 - 19 Wall parts for forming the cavity walls 3 - 6 and panel parts 20 - 23 has, the upper edges of the walls of the packaging carton form and connect the inner and outer wall parts together.

In addition, the packaging carton is provided with an arrangement for locking the packaging carton in its erected state. This arrangement includes inter alia locking ends that with 25 . 26 . 32 . 33 are designated.

More specifically, the latch assembly includes latching ends 25 ; 32 , respectively 26 ; 33 placed in two opposite first wall assemblies 8th . 10 are included, the locking ends in the erected state of the packaging box (see, in particular 2 ) inside a corresponding wall 4 , respectively. 6 located through a second wall assembly 9 . 11 is formed and arranged so that the walls 3 and 5 Locked in place by looking at the inside of the panel parts 21 . 23 rest against the inside. By the fact that the locking ends 25 . 26 . 32 . 33 in this way using the panel parts 21 and 23 kept down, will prevent the inner wall parts 12 . 14 which are connected to locking ends via respective fold lines, rotate in a direction towards the interior of the container in the triggering direction. The locking ends are designed with a suitable length so that the required Hebelarmbedingungen be achieved.

Out 2 It can be seen that the locking ends at their upper edges cutouts 77 which are for the purpose of ensuring that they are the outer ends of the locking ends that make up the underside of the panel parts 21 . 23 Touch, so that a larger lever arm is achieved. As well as out 2 and 3 As can be seen, the packaging carton is designed such that the outer ends of the locking ends are quite close to the fold line between the outer wall parts 17 respectively. 19 that in the walls 4 . 6 and the panel parts 21 respectively. 23 are included, are arranged. This position of the points of application of the force of the locking ends means that essentially the outer wall parts 17 and 19 perform a power transfer, without such a big moment on the panel parts 21 and 23 apply that there is a risk that the packaging carton will inadvertently be carried out in a unlocking direction.

Out 2 is apparent as the locking ends 25 and 26 about fold lines 40 with the inner wall part 12 the Wall 3 are connected while the locking ends 32 . 33 with the inner wall part 14 the Wall 5 are connected. Above are these wall parts 12 . 14 held substantially parallel to each other but at a distance relative to the outer wall portions 16 . 17 that in the walls 3 respectively. 5 by means of the panel parts 20 . 22 are included. fold 24 respectively. 31 (see both 2 as well as 4 ) serve as spacers between the respective inner and outer wall parts 12 ; 16 respectively. 14 ; 18 in the lower part of the packaging box. The flaps 24 and 31 are located above the lower part 7 and can abut it and with their outer edges on the inside of the outer edge parts 16 . 18 issue.

fold 27 and 34 connecting to the inner wall parts 13 . 15 that are in the wall assemblies 9 . 11 are included, serve as locking elements for this, ie for locking the inner and outer wall parts of the walls 4 respectively. 6 in a substantially parallel state at a mutual distance. These flaps 24 and 31 are in the lower part of the packaging box under the upper panel parts 20 respectively. 22 arranged in the same way, leaving the flaps 27 respectively. 34 in the lower part of the packaging box under the associated panel parts 21 respectively. 23 are arranged. Thus, the hollow property of the walls 3 - 6 receive.

Sloping chamfers, for example on the panel parts 21 - 24 , are present in a conventional manner, so that the panel parts fit together and edge to edge against each other in the corner region of the packaging box is supported.

In particular from 3 is evident, like flaps 27 - 28 are contained in the packaging carton in its erected condition; more precisely this is in 3 by means of the flaps 29 / 30 and 35 / 36 shown. More precisely, these flaps serve to erect the wall assemblies 9 . 11 respectively. 8th . 10 and are located in the corner area of the packaging box.

Thus, the locking ends 25 . 26 respectively. 32 . 33 with the inner wall parts 12 respectively. 14 the walls 3 . 5 connect and lock these by placing under the panel parts 21 . 23 are arranged, by means of the inner wall parts 13 . 15 and the flaps 27 . 34 be locked.

Preferably, the locking ends extend 25 . 26 . 32 . 33 in relation to the inner walls 12 . 14 obliquely from their attachment points outward to the ends 39 towards the locking end. This obliquity means that the ends 39 the locking ends adjacent to the fold line between the panel parts 21 . 23 and the outer wall parts 17 . 19 are arranged. For example, it is off 3 It can be seen that the supporting ends with cutouts 41 are provided. These have the task of facilitating the folding of the packaging box.

Out 2 it can be seen that the ends 39 the locking ends can abut in pairs. It is emphasized that this is not compulsory. On the other hand, such a concern may lead to the advantage that the locking ends are held in a more secure manner in an appropriate place, with their ends close to the outer wall parts of the walls 4 and 6 lie or touch, ie the locking ends are not inadvertently closer to the inner wall parts of these walls 4 . 6 or arranged next to them.

Out 2 and 4 For example, it can be seen that the lower part of the locking ends with cut 78 is provided. These have the purpose of enabling the flaps 27 and 34 the walls 4 . 6 can be moved under the locking ends, so that the flaps 27 . 34 effectively held in place.

When erecting the packaging box starting from the flat position according to 4 first become the wall assemblies 8th . 10 , which are provided with the locking ends, folded up and in to the center of the packaging box, so that the walls 3 and 5 be formed. After that, the wall assemblies 9 and 11 worked upwards and inwards to the walls 4 . 6 to build. By the fact that the flaps 27 . 34 be folded under the locking ends, in the end position, for the flap 27 in 2 is shown, the packaging board in its Ge All in all well-restrained in its erect condition.

In 4 Let the reference numeral x indicate the fold lines created by means of various perforations previously arranged in a line to each other. Finally, the fold lines obtained by means of folds are designated by the letter B.

of course is it is possible the embodiments described in this document in many ways without departing from the scope of the presented inventive idea departing. Accordingly, such possibilities of change are by experts included in the scope of the claimed protection. It will emphasizes that the invention is not limited to any special materials limited is, as long as the materials has such a foldability, the a request for the invention is. Thus, paper, cardboard and cardboard, plastic etc. as a material for the packaging box and its fastenings possible.

Especially It is emphasized that the packaging box is not necessarily four Own walls must, as shown in the drawings. Thus, according to the concept of the invention any even number of walls possible. It also emphasizes that the scope of the following claim 1 such embodiments, where the packaging box comprises only two walls and one floor, also includes. For example, the inventive concept with only two walls and running a floor, namely as corner packaging board, for example, for corner places during transport of objects such as plates, doors or similar to use. After all It is also stressed that the bottom of the packaging box is not necessarily Completely must be covering. Thus, would the bottom plate have a recess, in which case the wall structure would tend to to form a small arrangement with a central opening.
