Abstract

A box-shaped container is formed with two container halves joined together for swiveling along an adjoining edge. Each of the halves comprises a bottom wall, side walls protruding away from same, and rear walls joining them at their ends. The joining edge is formed by the upper end edges of the rear walls. To improve such a box-shaped container in that removal of the food stuff is simplified in a simple constructive manner and without dispensing with the advantages of known containers and at the same time avoiding dirtying the user, the side walls of the first container half are formed with increasing height, and the side walls of the second container half are formed with decreasing height in the respective direction to the front wall.

Claims

1. Box-shaped container (1) from two container halves (3, 4), joined together for swivelling along a joining edge (2), each of which comprises a bottom wall (5, 6), side walls (7, 8;

9, 10) protruding away from them and front and rear walls (12, 13, 14, 15) joining them at their ends (11, 28), wherein the joining edge (2) is formed by the upper end edges (16, 17) of the rear walls (14, 15),

characterised in that

the side walls (7, 8) of the first container half (3) are formed with increasing height (18, 19) and the side walls (9, 10) of the second container half (4) are formed with decreasing height (18, 19) in the respective direction to the front wall (12, 13).

2. Box-shaped container according to claim 1,

characterised in that

the height (18, 19) increases, respectively decreases continuously.

3. Box-shaped container according to claim 1 or 2,

characterised in that

the slopes of the free end edges (16, 17) of the side walls (7, 8;

9, 10) of both container halves (3, 4) are essentially equal.

4. Box-shaped container according to one of the claim 1 or 2,

characterised in that

the rear walls (14, 15) are essentially congruent.

5. Box-shaped container according to one of the claim 1 or 2,

characterised in that

one free end edge (20) of the front wall (12) of the first container half (3) has a convex curvature.

6. Box-shaped container according to one of the claim 1 or 2,

characterised in that

one free end edge (21) of the front wall (13) of the second container half (14) has a concave curvature.

7. Box-shaped container according to one of the claim 1 or 2,

characterised in that

the front wall (12, 13) of the first and/or second container half (3, 4) runs with a concave curvature between the side walls (7, 8;

9, 10).

8. Box-shaped container according to one of the claim 1 or 2,

characterised in that

the front wall (13) of the second container half (4) exhibits a lower height (22) than the front ends (23) of the side walls (9, 10) assigned to it and they protrude with an engaging section (24) in extension of the front wall (13) upwards above it.

9. Box-shaped container according to one of the claim 1 or 2,

characterised in that

the engaging section (24) exhibits a protruding latching lug (25) in extension of the side wall (9, 10).

10. Box-shaped container according to one of the claim 1 or 2,

characterised in that

with the container halves closed (3, 4) the latching lug (25) engages in a side open latching receptacle (26) on the side end (27) of the front wall (12) of the other container half (3).

11. Box-shaped container according to one of the claim 1 or 2,

characterised in that

the side wall (7, 8;

9, 10) exhibits a chamfer (30, 31) running downwards to the rear wall (14, 15) along its free edge (29) in the direction of the bottom wall (5, 6) on its end (28) assigned to the rear wall.

12. Blank (32) for a box-shaped container (1) according to one of the previous claims with first and second blank halves (34, 35), joined together along a swivel joint (33), for respectively the first and second container halves (3, 4), wherein each blank half (34, 35) comprises a central bottom section (36, 37) and side wall sections (38, 39;

40, 41) protruding away from it as well as front and rear wall sections (42, 43, 44, 45),

characterised in that

the side wall sections (38, 39) of the first blank half (34) increase in their height from the rear wall section to the front wall section (44, 42) and the side wall sections (40, 41) of the second blank half (35) decrease in their height (19) from the rear wall section to the front wall section (45, 43).

13. Blank according to claim 12,

characterised in that

the height (18, 19) increases, respectively decreases uniformly.

14. Blank according to claim 12 or 13,

characterised in that

a folding line (46, 47) joining a front wall section (42) and a bottom wall section (36) at least of the first blank half (34) runs with a concave curvature.

15. Blank according to one of the previous claims 12 to 13,

characterised in that

the swivel joint (33) exhibits a partially cut and/or perforated joining line (48) between the two rear wall sections (44, 45).

16. Blank according to one of the previous claims 12 to 13,

characterised in that
