According to one embodiment of the blank, a notch is adjacent to the cut. Other non-limiting aspects and advantages of the invention will appear during the following description, made with reference to the accompanying drawings in which - Figure 1 is a perspective view of a case according to the invention comprising a cover open and a cover partially closed, said case resting on its rear panel; - Figure 1A is a perspective view of an embodiment of the case; - Figure 2 is a perspective view of the case of Figure 1, its two covers being in the closed position; - Figure 3 is a plan view of the internal blank surface whose volume setting provides the case shown in Figures and 2; - The figure is a perspective view of the case of Figures 1 and 2 resting on its base having a closed cover and an open cover.

We will first describe Figures 1 2 and 3. The case 1 is substantially parallelepiped shape.

The top of the case 1 designates the parts of the case indicated by the arrow S in FIG. 1 and the base of the case designates the parts of the case indicated by the arrow B in FIG. 1.

The case 1 is delimited by panels which articulate with respect to each other by means of fold lines.

The case 1 comprises a body 3 comprising two open ends, allowing the user to access the space delimited by said body 3, and two covers 2 and 4, intended to close each of these two ends.

The body 3 is delimited by panels 9, 11, and 13 which are substantially rectangular.

The panel 12, called the front panel, is substantially parallel to the panel 9, called the rear panel.

The panels 11 and 13, called side panels, are substantially the same size and are substantially parallel.

The rear 9 and front 12 panels are substantially perpendicular to the side panels 11 and 13. The front panel 12 is delimited at its top by a straight edge 39 at its base by a straight edge 38.

The straight edges 38 and 39 are substantially parallel.

The side panels 11 and 13 are delimited at their top by a straight edge 42 and at their base by a straight edge The opening located at the top of the body 3 of the case 1 is delimited by the top of the rear panel 9 , the straight edges 42, 25, 39 and the curved edges 41. The opening situated at the base of the body 3 of the case 1 is delimited by the base of the rear panel 9 and by the edges 38 and 28.

size of the opening located at the top of the body 3 of the case is larger the size of the opening located at the base of the body 3 of the case.

The large size of the opening located at the top of the case has the advantage of facilitating the gripping of the articles contained in the case. The shape of this opening can be varied and little, for example, have an edge 39 in the form of an arc of a circle as shown in FIG. 1A.

The covers 2 and 4 are articulated to the body 3 by fold lines 22 and 29 respectively, forming a hinge.

To close the case 1 completely open, first close the cover 4 called the base cover, then close the cover 2 called the top cover. Closing the top cover 2 prevents the base cover 4 from opening.

To open the completely closed case 1, first open the top cover 2 and then open the base cover 4. The base cover 4 has a closing / opening panel 16 intended for close the opening located at the end of the base of the body 3 of the case 1 and a re-entrant tab 15 intended to be inserted inside the case 1 when said cover is closed.

The panel 16 is adjacent to the re-entrant tab 15 and is articulated to the latter by means of a fold line 30. The fold line 30 is substantially parallel to the fold line 29 forming a hinge.

The folding line 30 is interrupted at its median part by a cutout. The closing / opening panel 16 of the closed base cover 4 may include notch 32 in the form of an arc of a circle, adjacent to cutout 31. This notch 32 facilitates the gripping the re-entrant tongue of the top cover 2 closed from the case 1 as shown in FIG. 2.

The top cover 2 comprises - a front counter panel 7, intended to cover the front panel 12 of the case 1; - An opening / closing panel 8, intended to close off the opening situated at the end of the top of the body 3 of the case 1; and - at least one re-entrant tongue 6.

When the top cover 2 of the case is closed, the re-entrant tongue 6 is inserted through the cutout 31 in the closed base cover 4. The re-entrant tongue 6 is then substantially perpendicular to the front panel 12 and to the front counter panel 7 of the case 1.

According to a nonlimiting embodiment, shown in FIG. 1A, the fold line can be interrupted by two cutouts 31 in which re-entrant tongues 6 are inserted of a size adequate to the size of the cutouts. In FIG. 2, the side panels 11 and 13 of the body 3 of the case 1 are set back relative to the side edges 34 of the front counter panel and relative to the side edges 23 and 36 of the rear panel 9 of the case 1 closed.

The lateral edges 25 and 26 are thus supported on the front counter panel 7 and the lateral edges 24 and 27 are supported on the rear panel 9.

This has the effect of strengthening the front and rear faces of the case 1 defined respectively by the panels 7 and 9 and thus making it more difficult to crush said case by compression according to the arrows A and Z of the front and rear faces according to the figure 2.

On the other hand, the side panels 11 and 13 situated behind the lateral edges 34, 36, 23 of the two main front and rear faces of the case 1 are less easily accessible and are therefore more protected from shocks compared to side panels of a classic case.

The figure shows the case of Figures 1 and 2 resting on its base. The base cover is closed and the top cover 2 is open. The arrow C indicates the direction that the re-entrant tongue 6 will follow before being inserted into the cutout 31.

FIG. 3 represents the blank 5, the volume of which makes it possible to obtain the case as shown in FIGS. 1 and 2.

The surface of the blank 5 which is mostly invisible, when the blank 5 is set in volume thus forming the case 1, is the internal surface of the blank. Similarly, the surface of the blank 5 is mostly visible, when the blank 5 is set in volume thus forming the case, is the external surface of the blank.

The body 3 of the case is produced using - a rear panel 9; - a rear counter panel 10 - two side panels 11 and 13; - front panel 12; and - a bonding tab 14.

The rear panel 9 is adjacent to the rear counter panel 10 and is articulated to the latter via a fold line 23.
