Description

The present invention relates to a CD disc box comprising

  taking a bottom, a cover and a double bottom nested in the bottom.

  This double bottom has a space for the disc, surrounded by a rele-

  vee, a wide edge raised on the side of the lid joint, one or more openings in the edge of the double bottom housing, on the side located towards the

  wide edge, a window in the upper surface of the wide edge, a

  less in the form of a slide coming into the housing, to be actuated by the positioning of the disc in its housing and appear in the window to indicate the presence of the disc in the box. The slide o is a piece with an L-shaped section, the lower branch of which has a very open dihedral-shaped tongue, formed by a first flap connected by

  a hinge, at an angle a; a second part overflows natural-

  of the box cavity to be on the closing path of the

  circle and, in the absence of a disc, cooperate with the inner surface of the cover to be pushed towards the inside of the cavity and pull the slide in the retracted position or be subjected to the action of the disc placed in the housing to press against the inclined part of the raised edge

  and push the slide back into its indicator position.

  We already know such a CD disc box.

  o The aim of the present invention is to develop such a box and to improve the functioning of the slide and to develop the

visibility of its display.

  To this end, the invention relates to a box of the type defined above, characterized in that the dihedral-shaped tongue of the scau grout carries a tab which comes into resilient abutment against the lower branch of the slider, at least during the end of the movement. closing

of the joint.

  The elastic support of the tab of the tongue makes it possible to accumulate energy at the moment when the tongue in the form of a dihedron of the so coulisscau is pressed by the installation of a disc or by the firm structure of the box. This elastic support relieves the hinge connecting the lan watch to the remaining part of the slider and above all allows a hinge to be produced without having to give it a structure by its structure or its material.

particular ticity.

  Thus when the disc is released, or when the box is opened, the elastic energy stored in the combination of the tab and the tongue automatically opens the angle made by the tongue with the lower branch of the slide and lifts the lan watch elastically, in the waiting position or in place

  of a disc either closing the box.

  Advantageously, the tab is released from the surface of the tongue. This tab can in particular be cut out of manufacture in the surface of the tongue and be shaped to come out of the surface of the tongue and create the elastic support when the tongue is crushed by the disc placed in the housing or the closure of the neck. This embodiment is particularly simple and does not require any particular mold or manufacturing process except for the

  simple means dogoving the tab of the tongue.

  The lower branch of the slide has a stop against which the edge of the tab bears, at least during the end of the closing movement of the tongue, against the lower branch of the slide. This support reinforces the elastic action of the tab by causing the elastic deformation of the tab during closing and thus accentuating the elastic energy accumulated in the tab for the opening of the tongue when the disc is removed or opening the box. Advantageously, the stop is constituted by a box

  ment made in the lower branch of the slide.

  This housing arrangement also prevents the scau grout from having an excess thickness so that the disc can be posi

  naturally work in its double bottom housing.

  s For manufacturing, the tab is pre-stressed by hot deformation to disengage from the surface of the first flap of the tongue. This permanent deformation gives the leg a particular shape allowing it to create an elastic support when

  the crushing of the tongue against the lower branch of the slide.

  In the disc box, the slide is provided with a display element connected by a hinge and formed by an angle piece of which one part is intended to be displayed in the double bottom window and the other is behind the edge of the housing when the slide is in

  advanced position, indicating the presence of a disc in the box.

  According to another characteristic, the display element in the form of an angle of the slide is connected to the horizontal branch of the slide neck by an articulation and the assembly is made in a single piece of plastic material. This display element also constitutes an elastic support, by playing on the natural angle it makes with respect to the horizontal branch of the slide. I1 can thus push the slide towards the disc housing in the absence of a disc to initiate the movement

  retraction supplemented by closing the empty housing cover.

  s This angle-shaped display element also has the advantage of being housed in the opening of the edge and of being practical.

lie flush with it.

  This display element can receive a personalized label both on its upper face and on its lateral face so that the label is visible both from the top of the case and from the edge of the case. Thanks to the lighting or shadow effects projected, when the case is stored, it is very easy to see the presence or absence of a disc in the case. In addition, this slide is very easy to manufacture with extremely simple tools. The simple shape of the slide also makes it possible to place it in the open position, in the housing of the disc that in the empty case, for sale. It is enough for the user to provide the slide with personalized labels and to slide the slide into the opening of the case so that the slide becomes operational as a witness. The slide can be provided with a ledge coming in the window to appear at the edge of the window, above the edge or back of the box when the slide is advanced by the presence of a disc

in the box.

  It is particularly advantageous under these conditions for the slide to be completed by a flange under the indicator surface and serving as a stop and indicator surface appearing behind the back of the box from which a fraction of the raised part of the inner label has been removed. .

case (Figure 9B).

  According to Figure 1, the invention relates to a box that says CD composed of a bottom 1 to which is connected a cover 2 via a hinge 11 with pivots and housings. A double bottom 3 nested in the bottom. The double bottom 3 receives the disc 5 and, for this, it includes a disc housing 31 surrounded by a raised surface substantially occupying the four corners of the double bottom. This raised area ends with a wide edge 33, on the side of the joint 11 of the neck. This edge 33 is provided with an opening 36 opening at least

  in the housing 31 of the double bottom 3.

  Finally, the top of the wide edge 33 has a window 35.

  The opening 36 and the window 35 are located substantially at the

  s level of the axis of symmetry of the box.

  A slide-shaped indicator 4 is placed in a

  bile in the housing 31 to be actuated as shown in FIG. 1,

  by the front edge 51 of the disc 5 when the disc is inserted into the lo-

  ment. This movement of introduction of the disc 5 produces, on the one hand, the tilting of the slide 4 and on the other hand, its sliding so as to cause part of the slide 4 to appear in the window 35 and indicate

  the presence of the disc once the cover is closed.

  The slide 4 is a part having generally a sec-

  L-shaped tion with a lower branch 41 corresponding to the

  horizontal branch of the L-shape and a rising branch 42 corresponding to

  laying on the vertical branch of the L shape. The rising branch 42 carries an indicator surface 421 which, depending on the position of the slide 4, appears in the window 35 or is retracted under the wide edge. This indicator surface 421 includes indications or can receive a label.

quette.

  By its end opposite to that by which it is connected

  to the vertical branch 42, the lower branch 41 is connected to a lan-

  watch 43 by an articulation 44. This articulation is carried out by the

  material in which the slide is formed.

  : 5 This tongue 43 consists of two flaps 431, 432 forming between them a very open, relatively rigid dihedral. This tab is used to receive the end 51 of the disc 5 to be actuated like this

has been described above.

  The dihedral-shaped tongue 43 carries a tab 433 which o comes into the angle formed between the lower branch 41 of the slide 4 and

  the tongue 43 to constitute an elastic support between the lower branch

  41 and the tongue. This elastic support occurs either at least towards the end of the reclosing movement of the angle between the tongue 43 and the lower branch 41 of the slide, when a disc is placed in the housing 31 or at the time of closing. of the cover when

the housing is empty.

  The elastic support produced by the tongue 433 is created by the inherent elasticity of the tongue due to its shape and / or to the material. This tongue is advantageously made of the same material as

  the whole slide and in a single part with it.

  Advantageously, the tab 433 is cut in the first flap 431. Then this tab 433 is deformed when hot to disengage from the plane of the flap 431 while having the possibility, at the time of the crushing of the tongue 43 against the inner branch 41, of

  at least partially retract in the cutout 434.

  The elastic support of the tab 433 can result from its simple deformation but also it can be supplemented by the coming into abutment of the front edge 4331 of the tab 433 against a stop, for example the edge of a housing 411 produced in the lower branch 41. This housing can

be formed by a cutout.

  The front edge 412 of this cutout 411 is positioned to force the tab 433 to deform elastically under the effect of the disc 5

  is to store elastic energy.

  Figure 2 shows a slider-shaped witness 4A according to FIG. 1, with a slight variant concerning the structure of the second branch 42A and of the indicator surface 421A. The branch 42A reaches the edge of the indicator surface 421A opposite the side of the hinge 44A. This form of slide 4A can have advantages

  simplicity of realization since the space between the walls 4 2A, the banister

  che lower 41A and the tongue 43A is more dogged.

  This perspective view shows the 434A cutout and the

tab 433A.

  : 5 This view does not show a housing or stop similar to the housing 411 or its edge 412 forming the stop for the free edge of the tab 434A. These means can be provided in this embodiment. Figures 3A, 3B, 3C schematically show the three

  o steps of movement of a slide 4 according to the invention, independently

  ment of the practical achievements of the coulisscau. The movement shown is that of closing the slide under the action of a disc in place or closing the cover (neither the disc nor the cover are shown in these figures). The opening movement is done in reverse order, passing from the position of FIG. 3C to that of the

Figure 3A.

  Finally, figures 3A-3C do not show the displacement of the slide. In FIG. 3A, the slide is in the raised position or natural position, the angle a between the lower flap 431 and the lower branch 41 being the natural angle originating either from the molding or from a setting

shape after molding.

  Leg 433 is dogged with the plan of shutter 431. In this

  position, it possibly leans against the lower branch 41.

  The lower branch 41 has a stop 412. This stop 412 has the same reference as the edge 412 of the housing 411 in FIG. 1. This stop may be the edge of a housing not shown or a deformation produced in the branch 41. The role of this stop is stopped the sliding movement of the edge 4331 of the tab 433 to cause its elastic deformation at the end of closure. However, depending on the material in which the slide is made and also the lug 433, the sole elasticity of deformation of the lug 433 may be sufficient to accumulate

  is energy for the opening movement of the tongue 43.

  When one acts on the tongue 4 to close the angle a either by applying a disc against the tongue 4 to place the disc not shown in its housing or with the cover, when the empty box is closed again, the parts move as shown in FIG. 3B: the tab 433 moves either by bending or being deformed according to undulations, to absorb the reduction in space available since it comes against the stop 410. In the meantime, to pass from the position of FIG. 3A to that of FIG. 3B, the lower edge of the tab has

  traveled the distance to the stop 410.

  s The compression and deformation movement of the watch lane 433 then continues until the final position for fitting the disc or closing the cover; the tab 433 is retracted either in a cut made in the flap 431 or in a cut made in the lower branch 41 or in part in each of these two die cuts. The energy accumulated in the lug 433 constitutes a restoring force which lifts the tongue 4 when the empty box is opened or the disc is extracted, which favors the coming or returning of

  the tongue 4 in the "initial" position shown in FIG. 3A.

  The opening and lifting movement of the lan is made substantially in the reverse order of the order described above, that is to say that one passes from the position of FIG. 3C to that of the Figure 3B then to that of Figure 3A. The elastic deformation of the tab 433 and the accumulated energy are particularly important for initiating the lifting movement of the tongue 4. This makes it possible to relieve or even replace the elasticity of the hinge 44 at the most important moment, at the start of the movement of relaxation or lifting of the tongue and this all the more so as the elastic deformation of the tab creates an incomp arable fatigue which is less less than the fatigue which the hinge 44 may have undergone if it has to ensure relaxation alone . This effect of the tab is based both on its elasticity and on the lever arm of the point of application of the elastic force relative to the hinge 44. The latter

  o can be performed without creating an elastic restoring effect, which increases

will lie the lifetime.

  FIGS. 4A, 4B show in section the two positions of the

  slide, at the beginning and at the end of the closing of the empty box.

  Figures 5A, 5B show the transformation of the coulis-

  bucket shown separately for Figures 4A and 4B.

  FIG. 9A shows a variant of a 4D slide corresponding to

  laying in principle on the slide of FIGS. 6A and 6B, formed like the slide 4 of FIG. 1 for the parts not shown. The slide 4D comprises a display element 45D in the form of a square with two branches 451D, 452D; this element 45D is connected to the branch 41D

  of the slide 4D by an articulated link 46D.

  The branch 451D is intended to come into the window 35 of the wide edge 33 of the double bottom 3 moreover provided with the opening 36 for the passage of the slide 4D. The branch 452D comes against the edge or: 5 back 10 of the housing 1 in the position of FIG. 6A; this position is that

  4D slide when the case contains a disc.

  The edge 10 or back of the case 1 is made of transparent material

  and, the inner label 6, usual of CD discs, has been removed at the ni-

  edge calf 10, at least in its part corresponding to the slide or

to its branch 452D.

  In the case of a neutral box 1 for a blank or individually recorded disc, there is no label 6 in the box. The 4D slide is. preferably made in one piece by molding the piece or extruding a profile then cut to the width of the neck

  strip, the tab not shown being produced by a partial cut.

  This partial cut is made either before the cut of the slide or after it. The 46D joint works without excessive fatigue since whatever the position of the slide D, the angle between the parts D / 41D varies only between two very normal extreme values, close to the natural value, that is to say say that of the part at the time of molding

  or the manufacture of the hinge.

  When the slide 4D is slid to the right, the box having been closed without disc inside, the display element 45D switches as it appears in FIG. 9B, so that the branch 451D no longer appears in window 35 and branch 452D moves away from

edge 10.

  The disappearance of the branch 452B behind the edge 10 will be particularly effective if this edge 10 is of a transparency attenuated by a satin effect not making it possible to distinctly read information on the branch 452D which if it is directly behind the edge 10 and not at a certain distance as is the case of the fi

gure 9B.

  This effect can also be accentuated by the nature of the printing of the label affixed to the face of the branch 452D, so that the label is clearly readable only for reading perpendicular to its surface. The same remark applies to the label affixed on

branch 451D.

  The tilting movement of the element 45D is ensured either by the abutment of the edge of its edge 451D against the edge 351 of the window 35 or by a preload of the articulation 46D or else

  by the combination of these two means.

  FIGS. 7A, 7B show a variant of the double: 5 bottom 3C comprising the parts 37, 38 closing the window 35 and the step 36. These parts 37, 38, produced at the same time as the double bottom 3C during molding, are delimited by molding precuts 371, 381. The double bottom 3C is installed in the bottom 1 as shown in FIG. 7A and the parts 37, 38 can be detached by the user who will place a slide there, not shown. We then obtain

  the box already described, shown in Figure 7B.

  Figures 7A, 7B show a variant of slide 4C according to the invention. This slider is analogous for its basic shape to the slider 4A of FIG. 2 but it is extended at the front by two returns s5 or ledges; one of the reLords 223C is above the indicator surface 421C and the other reLord 424C is below this indicator surface. This last edge can be higher or lower as shown in the

dotted line.

  In the advanced position (figure 7A), the reLord 423C appears

  rait at the edge of window 35 above the front edge 10 of box 1.

  In this position, it signals the presence of a disc not shown

in the box or in the bottom 3.

  s This marking means can be very useful when the boxes are stacked perfectly and are sorted out. In a row, the front edge 432C of the indicator surface 421C appears very clearly.

  especially if it is distinguished from other parts of the box by its color.

  Conversely, when the indicator surface 421C is shrunk since the box is empty, the distance from the front edge 423C of the indicator surface 421C relative to the edge of the window 35 does not allow

  not to see the front edge which remains in the shade.

  This means makes it easy to detect the presence or absence of a disc in the box even when the boxes are stored

  s contiguously and that the window 35 is not visible.

  The visibility of the display on the back 10 of the box can be increased if the back is released at the level of the slide 4C. indeed, the box is. generally made of transparent plastic; its bottom as well as the back 10 are covered inside the box by a label 6 o plice of which the part 61 covers the interior bottom of the box and the part 62, raised covers the document 10; this label is stuck in the box

by the double bottom 3.

  According to the invention, at least the fraction of the raised part 62 of the label is removed, which is located opposite the slide 4C (this is underlined in FIGS. 7A, 7B by the absence of hatching in the part 62 at this point. place). So when the edge 424C comes against the back 10, it appears

will grate behind it.

  The rim 424C which serves as a stop, can be extended downwards and thus present a very visible surface especially if it is light in color. This surface can also receive a glued label which will also be very visible in the position of FIG. 4A whereas it will not be or with difficulty only in the position of FIG. 7B which

corresponds to the empty box.

  According to the manufacturing angle of the hinge 46D, between the 3s branch 452D and the branch 41D, which constitutes the natural angle, for example that shown in FIG. 9B, the articulation will have a spring effect on the slide 4D : the edge 453D can be pressed against the side 10 of the housing 1 to push the slide 4D to the right in the absence of antagonistic force exerted by the disc; thus naturally even before closing the cover of the empty case, the slide will already be pushed to the right (Figure 9B). This movement will be completed by the action of iron

cover size.

  s Finally, when this type of 4D slide is intended for a neutral casing, originally empty, it would be very easy to put a flat, open scissor neck in the cavity intended for the disc; the user can then fill the slide with its personalized labels before sliding the slide through the opening 36 and placing it in place

  o the case to constitute the witness.
