On the side opposite the bottom plate (3), the opposing customs walls (1) are partially tapered and are terminated by rectangular flaps (12, 13). The outer rectangular flap (13) is terminated with a tongue (15). The inner rectangular flap (12) is provided with a tongue (14) corresponding to the flap (16). The side walls (2) adjoin the free ends (21) to bevel (17) the customs walls (1). The sidewalls (2) are terminated by interlocking cut-outs (22).

Description

Technical field

Cardboard box is designed for packing especially piece goods. The shell is formed by a rectangular bottom surface where the flaps are adapted to be permanently closed and protrude from the walls of which they are part. The walls are connected by a flap.

BACKGROUND OF THE INVENTION

Two-piece boxes consisting of a lower part and a lid are commonly used for the packaging of piece goods. However, the lid may be spontaneously detached when handling the box, and when removing the goods it is necessary to handle the lid as a separate part that occupies the plan view of the handling space. Sometimes the lid is firmly attached to the bottom and only folds away from the bottom. Here, although the lid remains part of the bottom of the box, even after it has been opened. However, the box is also more susceptible to deformation when the lid is opened, as in the previous case. The stability of the boxes thus obtained will not be restored until the lid is lowered to the bottom.

There are known boxes that have a hinged lid and yet it is characterized by a relatively high stiffness even after its hinged. Such boxes are used, for example, to pack cigarettes. When the goods are removed, in this case a cigarette, the package is usually held in the hand. It is intended only for removal of goods for immediate consumption. Re-insertion of goods is therefore not foreseen.This are also addressed some packaging for candy. For packaging of piece goods, which will have to be repeatedly removed and put back into the box, for example in a shop during its demonstration or inspection, such a packaging is not suitable.

The essence of the solution

The invention is a cardboard box intended for packaging, in particular, piece goods, the shell of which is formed by a rectangular bottom surface. The flaps forming the bottom surface are • 4 4444 • · · ·

4 4 • 444 4 4 designed to be permanently closed and protruding from the walls of which they are part. The walls are connected by a flap. The packaging is intended for repeated opening as well as for removing and inserting piece goods. On the side opposite the bottom surface, the opposing faces are partially bevelled and terminated by rectangular flaps at the front. The outer rectangular flap is terminated with a tongue and the inner rectangular flap is tongue with a corresponding cut. The side walls adjoin the free ends to the chamfers of the end walls and terminate in interlocking cut-outs. This carton box can be easily opened, the goods removed and put back into the box without losing stability. After closing, the outer rectangular flap is fixed by the tongue inserted into the slit in the inner rectangular flap. The rectangular flaps connected in this way prevent the free ends of the side walls from being spontaneously detached by interlocking slots. The free ends of the side walls abut the chamfers of the front walls.

Between the chamfers extend the limit stops, which on the one hand increase the rigidity of the package by being connected to the opposite end walls by bending and by their free ends facing the opposite end wall, thereby contributing to maintaining the distance between the two opposite end walls.

Description of an exemplary embodiment

The housing is formed by a rectangular bottom surface 3, which in this embodiment is composed of flaps 31, 32, 33, 34 which, when folded together, are adapted to be permanently closed. Individual flaps 31,32,33,34 are part of walls 1,2. The floor area 3 can also be designed differently and is not subject to protection.

1, 2 are interconnected and are connected together by a flap 11. On the side opposite the bottom surface 3, the facing walls 1 are mutually opposed and partially tapered and ended by rectangular flaps 12,13. The outer rectangular flap 13 terminates in a tongue 14. The inner rectangular flap 12 is provided with a cutout 16 for the tongue 14 and is extended by a retractable flap 15. The side walls 2 abut the free ends 21 to the chamfers 17 of the end walls 1. 22. Spacer stops 18 extend from the chamfer 17.

The blank shown in FIG. 1 is folded according to the bends indicated and the adhesive flap 11 is glued to the edge of the side wall 2 at the opposite end of the blank. The flaps 31,32,33,34 fold down to form the bottom surface 3. The spacing stops 18 are folded in the bevel 17 at the indicated bending line so that they face each other.

The side walls 2 are inclined to the limit stops 18 and the cut-outs 22 at the free ends of the side walls 2 are locked together. The inner rectangular flap 12 is folded in to the latched slots 22 and the retractable flap 15 is slid behind the latched slots 22. The outer rectangular flap 13 is folded in to the inner rectangular flap 12 and the tongue 14 is slid into the cut 16. and the goods are easily accessible. The packaging also enables easy handling of the goods as well as their repeated insertion and removal.
