Abstract

A cardboard package is disclosed which comprises two subsidiary boxes (10, 11) which are initially joined to one another at a central fold line. The subsidiary boxes can be separated in the region of a central folding edge (14) at the central fold line because of weaknesses in the material (e.g. perforations), so that two self-contained subsidiary boxes, enclosed on all sides, are formed. The package is formed from a single blank. The blank is of a uniform width throughout--with the exception of the lid (29, 30). Pairs of side flaps (32, 33, 34, 35) are positioned on opposed sides of the blank to form the side walls (23, 24, 25, 26), with the side flaps in the assembled package being positioned in one plane without overlap and are held together by base flaps (36, 37).

Claims

1. A box made of stiff, foldable packaging material which comprises two separable subsidiary boxes (10, 11), which are folded out of a common one-piece blank, each of said subsidiary boxes including a from wall (12, 13), a back wall (21, 22), a base wall (27, 28), and side walls (23, 24, 25, 26), with the front wall (12) of one of said subsidiary boxes (10) and the from wall (13) of the other of said subsidiary boxes (11) adjoining one another before being separated, and connected to one another along an upper folding edge (14), means for weakening the material along said fold line to permit the separation of said subsidiary boxes, each of said side walls (23, 24, 25, 26), formed of pairs of individual folding tabs (33-35, 32-34), one of said pairs of said folding flaps joined to the front wall (12), back wall (21), and base wall (27) of one of said subsidiary boxes (10) and the other of said pairs of folding flaps joined to the from wall (13), back wall (22), and base wall (28) of the other of said subsidiary boxes (11), characterized in that:

said side flaps (32 to

     35) connected to said front walls (12,

     13) and back walls (21,

     22), are dimensioned such that, in the folded position and forming the finished package, the width of said side flaps (32 to

     35) corresponds to approximately half the width of the associated side walls (23 to

     26),

the respective base walls (27,

     28) of both of said subsidiary boxes (10,

     11) are connected laterally to base flaps (36,

     37) folded into the plane of the respective adjacent side wall (23 to

     26), and

the side flap (32 to

     35) of both of said subsidiary boxes (10,

     11) are connected to the base flaps (26,

     27) in the areas facing the base walls (27,

     28).

2. A box according to claim 1, characterized in that a lid (29, 30) for each of said subsidiary boxes is attached to opposed ends of the blank, connected to its respective back wall (21, 22), each lid being opposite the base wall (27) of each subsidiary box (10, 11), the width of each lid (29, 30) transverse to the longitudinal extension of the blank being greater than the width of the adjacent back wall (21, 22) such that each lid (29, 30) in the closed position terminates externally flush with the side walls (23 to 26).

3. A box according to claim 2, characterized in that an insertion tab (46, 47) is connected to an edge of each lid (29, 30) opposite the back wall (21, 22), and the width of each insertion tab (46, 47) transverse to the blank is slightly less than the width of the associated lid (29, 30).

4. A box according to claim 1, characterized in that the base wall (27, 28) of each subsidiary box (10, 11) is smaller in width, transverse to the longitudinal extension of the blank, that the from wall (12, 13), and the back wall (21, 22) correspond to the thickness of the material of the side flaps (32 to 35) for forming a respective external part of the side walls (23 to 26).

5. A box according to claim 1, characterized as being made of cardboard.

6. A box according to claim 1, characterized in that the base flaps (36, 37) are connected to the inner side of the side flaps (32 to 35).

7. A box according to claim 1, characterized in that the base flaps (36, 37) are connected to the side flaps (32 to 35) by gluing, sealing or stapling.
