## Abstract

Handling case with incorporated foldable lid. According to the invention, the case includes a lid made of two parts (4, 5) hinged to one another about a hinge (6) and which may be tipped against one another, hook-shaped mechanisms (12) being provided on the front part (5) of the lid which lock into slots (13) formed in a corresponding location along the edge (14) of the case when the lid is closed. The invention is applicable in particular to cases which can be stacked one inside the other when they are empty.

## Claims

### Claim 1

A handling case entailing a lid hinged to the body of the case along one of its edges along a hinge formed toward the upper edge of the case, characterized in that the said lid (3) is divided into two parts (4, 5) hinged one to the other about a second hinge (6) parallel to the first hinge (9), respectively forming a rear part (4) articulated around the said first hinge (9) on the said edge of the case, and a front part (5) hinged to the said rear part (4) of the lid about the said second hinge (6), the said front part (5) including, in the vicinity of the ends of the said second hinge (6), hook-shaped or similar parts (12) which in the tipped position of the lid are locked into slots (13) formed in corresponding positions along the edge (14) of the case, the said front part (5) also including conventional locking mechanisms (21, 22) to lock the lid onto the case.

### Claim 2 (depends on 1)

A case according to claim 1, characterized in that the said two lid parts include clippable type locking mechanisms (15, 16) which work together to permit the locking of the said front part (5) against the said rear part (4) when the two upper surfaces of the said two parts are tilted one against the other.

### Claim 3 (depends on 1, 2)

A case according to claim 1 or claim 2, characterized in that the aforementioned rear part (4) of the lid is larger than the said front part (5), the said second hinge (6) being offset toward the front side of the case.

### Claim 4 (depends on 2, 3)

A case according to claim 2 or claim 3, characterized in that the guide mechanisms which work in harmony and are provided in relief and hollowed out on each lid part (4, 5) surround the said clipping means (15, 16).

### Claim 5 (depends on 1, 2, 3, 4)

A case according to any one of the preceding claims 1-4, characterized in that the said cases are largely rectangular in cross section and that the said rear part (4) of the said lid is hinged along one of the long sides of the case.

### Claim 6 (depends on 1, 2, 3, 4, 5)

A case according to any one of the preceding claims 1-5, characterized in that the said cases have cross sections, known in and of themselves, which make it possible to store them in a stacked position.

### Claim 7 (depends on 1, 2, 3, 4, 5, 6)

A case according to any one of the preceding claims 1-6, characterized in that the said hinges (6, 9) are of an inviolable type.
