Description

"Disc box provided with a display means displaying the presence or absence of a disc in the box" Field of the invention

The present invention relates to a disc box provided with a display means for displaying the presence or absence of a disc in the box, that is to say a CD disc box, or the like comprising a case provided a cover and a double bottom nested in the housing and having a housing for the disc surrounded by a raised track and a wide edge on the side of the articulation of the cover, a slide coming into the housing having a body one end of which carries a naturally projecting flap in the housing to be pushed towards the interior of the housing by the cover (inactive position) or to be subjected to the action of the disc placed in the housing to come against the inclined part of the raised edge (active position). The invention relates, in general, to a CD disc box, that is to say a box of the type defined above and which can receive, in addition to the usual recorded CD discs, also CD-ROMs or discs. audio-video DVD.

To simplify the presentation, the following will only be a CD disc box. Prior art

Such a CD disc box is already known, in particular according to documents FR 00 08 220 and FR 02 02 194. Aim of the invention The aim of the present invention is to develop a CD disc box of the type defined above. , allowing an even more visible and, if necessary, tactile display of the presence or absence of a disc in the box, in particular in CD disc boxes having a double transparent bottom. The invention also provides great possibilities for individualizing the box and, where appropriate, the disc to facilitate the identification not only of the absence of a disc in a box, especially if it has a double transparent bottom, but also to easily find the disc associated with a box and to create a large display surface, easily readable or locatable by also developing very advanced, pre-established or left means, at least in part, of classification, identification or individualization , at the initiative of the user. Statement of the invention

To this end, the invention relates to a CD disc box of the type defined above, characterized by a flap housed in the cavity behind the back of the case under the double bottom, this flap being connected by an articulation at the end. of the slide other than that carrying the actuating arm, to come

- in the active position against the back of the case, when the slide is pushed back by the disc placed in the case, or

- in the inactive position against the bottom, when the slide is pulled by the cover in the absence of a disc in the housing.

The flap housed in the cavity and movable between an active position and a rest position constitutes a very effective display means for indicating the presence or absence of a disc in the box. This means is all the more effective as it can extend over the entire length of the back, behind it and thus appear in the active position, applied against the back to reveal the indications carried by this flap in place of the usual label or be linked to the back label to make it appear or fold it down. These indications relate to the disc placed in the box or disc with which the box is associated. It can be a printed strip containing the name of the disc or the name and blank parts for inscriptions left in the description of the user if it is a rewritable disc. The preprinted strip applied on the shutter is preferably a strip printed separately from the slide and its shutter. Conversely, when the slide and the shutter are in the inactive position, the shutter is tilted backwards, practically flat against the bottom of the housing inside the cavity under the wide edge of the double bottom and thus the inscription n 'does not appear on the back. This absence of registration constitutes an excellent witness of the absence of a disc in the box. The witness is all the more perceptible since it is in the place of the label on the back and that this absence is noticed instinctively. The absence of registration appears in the case where there is a back label, glued to the flap or in the case of the absence of label.

In general the boxes are provided with a label fixed against the bottom of the box by the double bottom and a raised edge appearing on the back of the box which is generally transparent.

It also identifies the disc that should be placed in this box if the box has no other information. For this- there, we push the slide by hand forward to tilt the shutter behind the back of the box and read the name of the disc that should be in the box.

This is useful if the double bottom is made of a non-transparent plastic material so that the cavity and the flap can only be seen through the back of the box.

According to another advantageous characteristic, an auxiliary flap connected to the branch of the slider in particular by a hinge and it comes in front of the inclined wall of the double bottom and in particular it bears against the latter when the slider is retracted and the flap in the position of rest.

This auxiliary flap performs a reverse movement to that of the flap itself or main flap. When the main flap is retracted, the auxiliary flap becomes visible and readable through the transparent back of the box. Conversely, when the flap is applied against the back of the box in the active position, the auxiliary flap is no longer visible since it is hidden by the main flap.

According to an advantageous characteristic, the width of the auxiliary flap is sufficient for the edge of the flap other than that of its articulation to the arm of the slider to brace or rest in the corner formed by the section of the double bottom, between its wide edge and its inclined wall. Therefore, the auxiliary flap cannot fall against the arm and it remains trapped in the angle formed between the wide edge and the inclined wall of the double bottom whatever the movement or the position of the slide between the active position and the position. inactiye.

According to another advantageous characteristic, the auxiliary flap is rigidly connected to a base, itself connected to the branch of the slide, the base moving in the corridor with the slide; the auxiliary flap being housed in the cavity behind the hinge of the flap to remain substantially parallel to the back of the housing regardless of the position of the flap, and the auxiliary flap appears across the back when the flap is retracted in the inactive position.

This auxiliary flap which performs only a translational movement behind the hinge connecting the branch of the slide to the flap appearing directly behind the bottom of the housing constitutes a particularly effective display means since this auxiliary flap remains parallel to the back, it is particularly well readable; the indication it carries is not distorted by the inclination. Also as in the inactive position of the flap, when the latter is folded against the bottom of the housing, this auxiliary flap is particular, clearly visible in the cavity.

The realization of the shutter with the auxiliary shutter and the slide is particularly simple. It is the same for the establishment of this device in a housing provided with a corridor for receiving the slide.

Advantageously, as the auxiliary flap remains parallel to itself during the sliding movement of the slide, it is advantageous to use all the space available in height and to give the auxiliary flap a height substantially equal to the height of the cavity. . But for the length, it is interesting that the auxiliary flap does not have too long a length, all the more since the auxiliary flap must constitute an element which is clearly distinguished from the usual display by the back label or the flap carried by the branch of the slide and which preferably occupies the entire length of the back. Advantageously, at the connection between the arm and the branch of the slide, there are provided two tabs projecting laterally and which are elastically deformed when the slide is pushed into the active position, so as to push the slide in the opposite direction when 'we extract the disc from its housing in the double bottom.

According to another advantageous characteristic, the branch of the slide is formed of two parts coming from either side of the base carrying the auxiliary flap. This embodiment is particularly simple and it allows in particular the free play of the branch (in its two parts) of the slide connected to the flap by an articulation in height. These two parts of the branches can thus be raised and follow the movement of raising the articulation between the parts of the branch and the flap while the auxiliary flap and its base constituting a rigid assembly remain in place in the interval between the two parts. of the branch behind the articulation of the branch and the flap.

According to another advantageous characteristic, the flap is provided with an adhesive to be fixed to the return of the label at the bottom of the case which rises against the back of the case to cause this return in the position applied against the back or in the inactive, retracted position. against the bottom of the case. This solution is very interesting for transforming or equipping a box which already has a bottom label or which receives one.

The device is provided on its flap with an adhesive surface which is itself protected until use by a peelable film such as a film silicone. After placing the device in a box, the peelable film can be removed from the surface of the flap to apply the flap against the return of the bottom label. Thus when the disc is extracted from the case and the latter is closed, the movement of withdrawal of the slide causes the flap to tip over and consequently the back flip to tip over since the latter is glued to the flap. In this case the auxiliary component and the information it carries appear particularly clearly and unequivocally.

To favor the distinction between the flap and the auxiliary flap or the return of the label, it is advantageous that the auxiliary flap has a length which corresponds only to a reduced fraction of the length of the back of the housing.

According to the relative geometrical dimensions of the shutter, of the arm and of the auxiliary shutter, in the rest position of the main shutter, the auxiliary shutter will be brought closer or closer to the inclined wall. This auxiliary component advantageously includes a very legible indication, for example in fluorescent ink indicating the absence of a disc in the box. Thus, although the auxiliary flap is in the display position, placed at the bottom of the cavity, on the side of the inclined wall, and even if the double bottom is made of non-transparent plastic, it will be bright enough to be very noticeable at across the back of the box, regardless of the lighting conditions, even if the empty box is stored in a stack of other boxes of this type.

According to an advantageous characteristic for cinematics, the auxiliary flap is articulated to the branch between the articulation of the flap and the zone of the branch which remains in the cavity even when the slide is in the inactive position.

According to another advantageous characteristic, an auxiliary flap coming in front of the inclined wall of the double bottom, is fixed to this inclined wall or at the wide edge, in the cavity delimited between the housing and the double bottom.

In this case, the auxiliary flap is mechanically independent of the slide and the main flap. It is always in the display position applied more or less against the inclined wall of the double bottom. The auxiliary flap can be fixed to this inclined wall at least in part, for example along its edge by an adhesive. It can also be fixed against the underside of the wide edge by an edge, also by an adhesive. This installation is done very simply on the double bottom out of the box.

According to another advantageous characteristic, the branch of the slide is articulated at the upper edge of the flap. In this case, the arc shutter slider the main flap or flap against the back of the housing, at its upper edge, the lower edge of the flap state applied in the lower corner of the cavity at the junction of the back and the bottom of the box.

From the kinematic point of view, it may be particularly advantageous to articulate the end of the ram branch in an intermediate position between the upper edge and the lower edge of the flap. This keeps the branch of the slider in a more straight, non-bent or very slightly bent position, close to the bottom of the box, and whether this branch is in the active position or in the rest position. In addition, there is a leverage effect for the tilting of the flap. Advantageously, the flap extends over a significant part of the length of the back of the housing and, preferably, over the entire length of the latter. The shutter is then connected to the branch of the slide which will have only a relatively small width compared to the length of the shutter. The same remark applies to the auxiliary flap which, according to an interesting variant, extends over the entire length of the cavity behind the back of the housing in order to have as large a viewing surface as possible.

The slide with its flap (main flap) and, if necessary, its auxiliary flap can be produced in a single piece, for example made of plastic with hinges produced in the mass. These elements can also be in several parts, for example, the slide and its front part of a certain width connected by the articulation to the main flap and, on this very wide part (corresponding to the direction of the length of the back) , the articulation of the auxiliary flap. This part of the branch of the slider can be produced separately from the other parts of the slider due to this difference in width, the assembly being able to be assembled, for example, by welding, gluing, heat-sealing.

The installation of the slide with the flap or flaps and the installation of a separate flap against the inclined wall of the double bottom are very easy once the double bottom is removed from the box. drawings

According to Figures 1 to 20, the invention relates to a disc box such as CD, DVD or other discs. This box consists of a box 1 provided with a cover 2 connected to the box by an articulation perpendicular to the sheet of figures. The housing 1 and the cover 2 are, in general, made of transparent plastic; the housing receives a double bottom 3 nested in the housing 1 by means of clipping or locking by shape, not shown.

The double bottom forms a housing 31 for a disc 5. This housing 31 is surrounded by a raised pad 32 and, on the side of the articulation between the cover 2 and the housing 1, there is a wide edge 33 which overlaps the cover 2 The cover 2 has a spout 21 on the side of its articulation. This spout 21 is an edge extending over the entire depth of the cover (direction parallel to the direction of the axis of the joint). On the side of the wide edge 33, the double bottom 3 has an inclined wall 331 which descends to the bottom proper of the double bottom 3.

At its base, the inclined wall 31 has a cutout 122 which does not extend over the entire depth of the inclined wall 331 but only over a small fraction thereof. This cut-out 122 is extended at the bottom by a housing 121 of substantially the same width which is, for example, of the order of 1 or 2 cm.

The box comprises a slide 4 in the form of a band, folded with elastic joints having a branch 1 placed in a sliding manner in the housing 121 and ending at one end by an unreferenced articulation connecting the branch 41 to an arm 42 in the form of open V naturally projecting into the housing 31 of the double bottom 3. The slide 4 is pushed from its inactive position shown for example in Figure 1 in its active position shown in Figure 2. In this position, the disc 5 flap the arm 42 against the inclined wall 331 and the bottom of the box 1 and at the same time slides the slide 4 to the left according to the drawings relative to the completely right position limited by the end of the corridor 121 in the position shown in figure 1.

In the inactive position (that is to say in the absence of a disc in the box), when the cover 2 closes, it pushes and slides the slide 4 while pressing against the end of its arm 42 in the position represented for example in FIG. 7. For these figures, the same previous references to designate identical or analogous elements.

According to the first embodiment (Figures 1 and 2), the slider 4 comprises at the end of its branch 41, opposite that connected to the arm 42, a flap 61 housed in the cavity 7 delimited between the back 11 of the housing 1 and the front part 331 of the double bottom 3, under the wide edge 33 and the inclined wall 331. This flap 61 has a width (1) less than or at most equal to the height (h) of the back 11. Its length (or depth) in the direction perpendicular to the sheet of the drawing is preferably practically as great as the length of the back 11 (i.e. the measurement of the back in the same direction).

The flap 61 is connected to the end of the branch 41 by a hinge 62. This hinge can be constituted by a hinge in the mass if the slider 4 is made in one piece with the flap 61. Insofar as the slider 4 has a relatively small width, of the order of 1 or 2 centimeters, it can be widened in the front zone 41 connected to the hinge 62 so as to have a greater depth and, preferably, equal to the depth of the flap 61. Thus, the hinge 62 extends over the entire length. Controlled by the slide, the shutter 61 can take an inactive position (Figure 1) or an active position (Figure 2). In the inactive position, the slider 4 is pulled to the right in the corridor 121 of the double bottom 3 either by natural expansion or by driving through the cover as will be seen next, for example in FIGS. 6 and 7. In this inactive position, the flap 61 is more or less flattened against the bottom 12 of the housing 1. In the active position, when the slider 4 is pushed to the left (according to FIG. 2) by placing the disc 1 in the box, or more exactly in its housing 31 of the double bottom 3, the slide 4 pushes by its branch 41 on the joint 62. As the edge 611 of the flap 61 is supported in the corner 13 at the junction of the bottom 12 and the back 1 of the box , the flap 61 switches in the direction of the arrow A (FIG. 1) to come to bear against the back 11 and appear behind the transparent back 11 like the rest of the housing 1. This situation is indicated by the arrow VI. It is thus possible to see the flap 61 and especially to read the indications which it carries. These indications may correspond to the description of the disc 5, for example the title of the recording. It can also be a space reserved for free registration in the case of a recordable or recorded disc 5 by the user. When the disc 5 is removed and the cover is closed, the slider is pulled into the position shown in FIG. 1 and the flap 61 is no longer visible behind the back 11 or at least is not clearly visible when 'we look in the direction of arrow VI. The user of the box can thus see that the box is empty without even having to open the box. This is done regardless of the position of the box, for example if the box is stored in a stack with other boxes.

Figures 3 and 4 are views similar to Figures 1 and 2 showing another embodiment of the invention.

This variant according to the invention consists of a slide 4 with a branch 41 placed in the box under the same conditions as above. The front end of the branch 41 is connected by a hinge 62 to the flap 61. In addition to this flap 61, there is an auxiliary flap 63 connected to the branch 41 by a hinge 64. The flap 63 can occupy the entire depth of cavity 7 or only a fraction of this depth. Its width (measured in the plane of Figure 3) is close to the height of the cavity between the bottom 12 and the wide edge 33 or practically equal to this height. The hinge or articulation 64 is located between the articulation 62 of the flap 61 and the zone of the branch 41 which always remains in the cavity 7 even when the slide occupies the rightmost position, like that represented in FIG. 3 .

Under these conditions, when the slide 4 is in the inactive position, the auxiliary flap 63 is more or less applied against the inclined wall 331 or is placed in front of the latter in an inclined or straight position. The auxiliary flap 63 then occupies its largest visible surface through the back 11 which makes it possible to see it clearly when looking through the back 11 in the direction of the arrow V2. In this position, the flap 61 is more or less flattened against the bottom 12 and is not visible. The operation of this slider 4A is the same as the slider 4 explained with the aid of FIGS. 1 and 2. In the inactive position, the slider 4A occupies the position of FIG. 3; the flap 61 is not visible through the back 11 and the auxiliary flap 63 clearly visible so as to actively signal that the box is empty. The signaling is thus double, on the one hand the retraction of the flap 61 which is not visible and on the other hand, the visible presence of the flap 63.

The active position is shown in FIG. 4. In this position, the flap 61 is applied against the back 11 of the box 1 and the vo- let 62 is hidden behind shutter 61 and is not visible. Only the flap 61 is visible, as indicated by the arrow VI.

Figures 5 to 8 show different phases of use or operation of the box. Figure 5 shows the cover closed over the arm 41, the disc 5 being placed in the box. This state is displayed by the presence of the flap 61 behind the transparent back 11 (arrow VI indicating the view of the flap 61 while the flap 63 is hidden).

Figure 6 shows the opening of the cover 2 after extraction of the disc. The arm 42 is raised around its articulation with respect to the branch 41 but, at this time, the flap 61 is still in its place behind the back 11 or, at least, it can still be in this place. The flap 63 is always retracted. But the position shown in Figure 6 is a transient position. If, from this position, the cover 2 is closed as shown in FIG. 7, the spout 21 pushes the arm 42 back to its rightmost position in the corridor 121 (if this movement has not already taken place naturally under the effect of an external force, for example weight, if the housing is tilted). In this position, the slide is blocked and the auxiliary flap 63 appears at the bottom of the cavity 7 through the back 11 as shown by arrow V2, the flap 61 not being visible or readable in this direction through the back 11 .

FIG. 8 shows the situation in which the parts are found when the cover 2 is opened starting from FIG. 7. In this position, the arm 42 has relaxed but the slide has not changed place. The auxiliary flap 63 is always visible. But it is a transient position followed by the installation of the disc and closing of the cover to pass into the position of FIG. 5 or reclosing of the empty box to then return to the position shown in FIG. 7. The Figures 9 and 10 show another embodiment which differs from the previous embodiments by the shape of the flap 61 A, that of the auxiliary flap 63 being practically the same as above.

According to this variant, the branch 41 of the slide 4 is connected to the flap 61A by a hinge 62A situated between the lower edge and the upper edge 611A, 612A of the flap 61 A. The movement of the flap 61A is thus accentuated with respect to the movement of slide 4 and its branch 41. The stroke to be carried out to raise the shutter 61A or to lower it is reduced compared to the case of the preceding figures.

In this variant, there is also an auxiliary flap 63A whose role is the same as in the previous figures. The role of shutter 61A which can also be called main shutter, is the same as above.

Figures 11, 12, 13, 14 show different positions of the flaps 61A and 63 depending on the use of the box.

In FIG. 11, a disc 5 is placed in the box. The flap 61A is applied against the transparent back 11 and the auxiliary flap 63, which remains behind, is not visible.

Figure 12 shows the opening of the box and the extraction of the disc. The arm 42 is raised but the slide has not yet changed place so that the flap 61 A has remained in its place and the flap 63 also. Figure 13 shows the closure of the box in the absence of a disc. In this case, the spout 21 of the cover 2 pushes the arm 42 to the right in the corridor 121 of the double bottom and, by this traction, it switches the flap 61A while the auxiliary flap, bearing against the inclined wall 331, straightens up and goes into a more or less vertical position relative to the box, so that the surface of the flap 63 is clearly visible through the back 11, as shown by arrow V2.

Figure 14 shows the opening of the box starting from the position of Figure 13.

Figures 14 and 15 show another alternative embodiment of the invention. This variant differs from the previous figures in that the slide 4A comprises a flap 61A connected to the end of the branch 41 by a joint 62A located between its two lower and upper edges. In this variant, the auxiliary flap 63A is not connected to the branch 41 but is applied integrally to the inclined wall 331. It can be by gluing. It can also be connected by a lug 64A fixed to the wide edge 33 below the latter in the cavity 7.

The auxiliary flap 63A or what takes the place of an auxiliary flap will thus be visible in the inactive position of the slider 4A shown in FIG. 15. It will be hidden in the active position of the slider 4A shown in FIG. 16 but then the flap 61A will be visible behind the back 11.

At the same time, it will hide the auxiliary flap 63A.

Figures 17, 18, 19, 20 show the positions of use of the box of Figures 15 and 16 in states of use analogous to those described above with regard to the various previous embodiments.

Figures 21 to 26 show another embodiment of the invention. In these figures, the elements identical or analogous to those of the preceding embodiments bear the same references.

In this embodiment, the slide 4 includes a branch 41 connected by a hinge 62 to the flap 61.

In addition to the flap 61, an auxiliary flap 65 is provided which is rigidly connected, that is to say in a non-articulated manner, to a base 66 itself connected to the slide 4.

Thus the base 66 is connected to the branch 41 of the slide 4 near its connection with the arm 42 or at this connection.

The base 66 slides integrally in movement from the slide 4 in the corridor 121 while remaining applied against the bottom 12 of the housing 1; the auxiliary flap 65 remains parallel to itself during this movement of the base 66 accompanying the movement of the slide 4.

The auxiliary flap 65 has a height substantially equal to that of the cavity 7 and it is placed behind the hinge 62 connecting the branch 41 of the slide 4 to the flap 61. When the flap 61 is advanced in the active position behind the back 11 of the box 1, the auxiliary flap 65 which is behind the flap 61 is hidden by it.

When the flap 61 is removed in the inactive position, flattened against the bottom 12 of the housing, the auxiliary flap 65 is certainly set back in the cavity 7 but it appears through the transparent back 11. It is particularly advantageous from the point of view of the appearance and the signaling effect that the auxiliary flap 65 occupies only a short length of the back of the housing 1 and in particular a length of the order of 1 to 2 cm in the middle of the back 11 of the box 1. This makes it possible to highlight even better the message displayed by the auxiliary flap 65 compared to the usual appearance that the back 11 of the box occupies by the label return or by part 61.

FIG. 21 shows the flap 61 folded down in the inactive position against the bottom 12, the auxiliary flap then appearing through the back 11.

FIG. 22 shows the flap 61 in the active position, applied against the back 11 of the housing 1. The auxiliary flap 65 is then hidden behind the flap 61 although it has come closer to the back 11 following the movement of the slide 4 and its branch 41. Besides, this close position of the auxiliary flap 65 is interesting since the flap is well hidden by the flap 61 and can not be seen obliquely either the top of the back 11, or through the wide edge 33 of the double bottom if the latter is transparent. This promotes a clear display of the two positions, i.e. the presence or absence of a disc in the box. Figures 23, 24 show an interesting embodiment of the auxiliary shutter slide according to Figures 21, 22. The top view of Figure 23 shows the branch 41 of the slide 4 formed of two parts 41-1 and 41-2. These two parts are connected parallel to the flap 61 by two articulation parts 62-1; 62-2. The two parts 41-1; 41-2 are connected as before to arm 42.

The auxiliary flap 65 perpendicular to its base 66 is located just behind the line of the joint 62, 62-1; 62-2. The flap 65 is perpendicular to the sheet of the drawing and the base 66 is located between the two parts 41-1; 42-2 of the branch 41 of the slide 4. Thus the movement of the flap 6 and that of the auxiliary flap 65 are integral but the two flaps 61, 65 perform. different movements: the flap 61 pushed by the branch 41-1; 41-2 of the slide switches from its more or less flattened position against the bottom 12 towards a raised position against the back 11 of the housing while the auxiliary flap 65 follows the translational movement of the slide while remaining parallel to itself, its base remaining applied against the bottom 12. This separation of movements is possible because over at least a large part of its length, the base 66 is not connected to the branch 41 or to its two parts 41-1; 41-2. For reasons of symmetry, it is interesting that the auxiliary flap 65 is located between the two parts 41-1; 41-2 of the branch 41 so that the ends of the branch 41 connected to the joint 62-1; 62-2 can be lifted with the flap 61 raised. In addition to the efficiency of the display, this solution also has the advantage of being very simple.

Another embodiment not shown may consist in reversing the arrangement of the branch 41 and the base 66 by placing the base 66 on one side or on both sides of the branch 41 then in one piece. But in this case the auxiliary flap will be placed on one side or in two parts on the two sides of the branch 41 to allow passage and lifting of the branch at the same time as the flap 61 rises.

While in the above embodiment, the case is not provided with a bottom label or that this does not go up against the back 11 of the housing, FIGS. 25, 26 show an advantageous embodiment for a housing provided with such a label.

In this case, the flap 61 has an adhesive face (on the side facing the back 11). This adhesive face (covered with the production of a peelable film), can then be glued against the return 211 of the bottom label 212 usually placed in the housing 1 under the double bottom 3. This allows on the one hand to display the references of the disc of this case by the original information and on the other hand to remove this information (text, drawings or logo) when the box is closed without the disc.

In the various embodiments, in particular according to FIGS. 21-26, the installation of the slide and its flaps is done in a simple manner by removing the double bottom 3 and installing the flaps 61, 65 with the slide in the bottom of the housing. 1 then put back the double bottom. In the case of a bottom label, the flap can then be stuck against the return of the label under the double bottom 3.

According to a variant shown in Figures 23, 24 the two sides of the branch 41 or branch parts 41-1; 41-2 carry at the connection between the branch 41 and the arm 42, two elastic tongues 43-1; 43-2 coming laterally projecting. These elastic tabs bear against the edge of the opening 122 of the inclined wall 331 of the double bottom 3 when the slide is pushed back by the disc in the active position. The elastic deformation of these two tongues makes it possible to initiate or support the reverse movement of the slide in the opposite direction when removing a disc.

As indicated, the component (or main component) of the various embodiments may include inscriptions made by the manufacturer of the box or the one who loads the boxes with the discs. The indications can be in the form of labels stuck on the shutter. For the auxiliary shutter, this is generally a very visible indication to indicate the absence of a disc. This indication can be a readable indication or a symbol, preferably in a fluorescent color so as to be clearly visible even when the box or the back are dimly lit as can be the case when the box is stored in a stack. The indications carried by the auxiliary flap are either labels or indications directly printed on this flap, in particular when it is the last embodiment described, the flap not being directly connected to the slide while cooperating closely with it.
