The cardboard sides are folded over the top and the rest of the cardboard base are folded around to provide complete protection.

Description

Cardboard container for packing fragile objects Containers made of

  cardboard, particularly of corrugated cardboard, can be divided into two broad categories, namely those with a fixed volume and those whose volume is

  is adaptable to that of packaged objects.

  When it comes to transporting objects that are all identical, one adopts once and for all a container of fixed volume, and when these objects are fragile or delicate, one places wedges which perfectly fill the empty spaces included between the packaged object and the container. We know that if, in addition, the objects have complicated shapes, these wedges are made especially to fit perfectly on the object and

  apply exactly against the inside walls of the container.

  If, on the contrary, the same container is to be used for packaging objects of different volumes, for example identical to each other but in a variable number or different from each other, it is necessary to have calibrations that are themselves adaptable: stuffing materials , inflated air pads, etc. Containers with variable volume obviously adapt better to the diversity of

  shipments of various objects and / or in variable numbers.

  This is the case, for example, with shipments of books, magazines, cassettes, compact discs,

  and other articles sold by correspondence.

  The tightening of the objects that can be obtained with these adjustable containers is a guarantee of robustness and security, because the objects are immobilized in the container and do not

  can be damaged by friction or shock.

  But experience shows that the many and severe handling of containers sent by post or courier, causes damage to packaged objects, even through the relatively thick walls of the containers.

corrugated cardboard.

  This is the case, in particular, of enclosures which contain compact discs and which

  have two fragile areas that are often damaged: the center and corners.

  In the center is a disk holding device which is made up of small elastic claws that break easily when compressed, which often happens due to compressive forces and shocks applied perpendicular to the plane.

of the case.

  The corners are in themselves very exposed to impact, especially during falls, and near two of the four corners of the housing is the hinge of the lid, formed of

  small lugs engaged in paws, the whole being very small and very fragile.

  The present invention relates to a new container which is provided with means

  particularly effective and simple to protect fragile objects.

  To this end, the subject of the invention is a cardboard container or similar material intended for packaging fragile objects, in whole or in part, formed of a blank which is formed from at least one flat blank and which has flat various components, namely a planar polygonal base recipient of the objects to be packaged and panels or panels that are adjacent to the base and which must be folded, folded over the objects arranged on the base, and then held in this way. so-called "closing" position, characterized in that wedging elements must be interposed on the one hand between the base and the objects and on the other hand between the objects and at least one panel or flap folded, each wedging having the least an opening that goes through it and that must be

  placed in line with fragile parts or objects arranged on the base.

  According to other features of the invention: => the container being at variable height depending on the nature and / or the number of objects arranged on the base, it is characterized in that at least one of the present settings an opening is single and oblong, or multiple and at most barlongue, to always be in line with fragile parts or objects arranged on the base, regardless of their number, their arrangement and / or their total height , eligible because of the format of the container considered; => the container being of variable height depending on the nature and / or the number of objects arranged on the base, it is characterized in that two wedges are likely to overlap in part, they each have a single opening and oblong, multiple and at most barlongue, so that an opening of a wedging is always facing an opening of the other, at least in part, regardless of the extent of recovery of said wedges; each wedging is formed of an independent plate; = the wedges are formed by a single plate to be folded to form two parallel planes united by a segment which is perpendicular to them and which has the same height as that of the objects; at least one of the wedges is formed by an element integral with the container itself, namely one or more cut shutters holding either at the base or a panel; = at least one of the wedges is formed by at least one of the constituent elements of the container itself, in particular a panel or shutter; each wedging comprises at least one opening cut inside the contour of said wedging; each wedging comprises at least one opening cut in an edge of said wedging, that is to say that it is cut to beyond the contour of said wedging; => the objects to be arranged on the base to be compact discs encased in a housing, the opening of the wedges is in line with the center of the disks; => each wedging comprises at least one notch notched in an edge of said wedging, including cut edges; = the objects to be arranged on the base to be compact discs enclosed in a housing, a cut off of the wedges is at least two corners of said housing; at least one of the wedges is provided with a long-acting adhesive covered with a removable protective tape; the container is equipped with a long-acting adhesive covered with a removable protective tape; the wedging being secured to the container itself, the cushioning adhesive and the adhesive

  of the container are in the extension of one another.

  Figures 28 and 29 are two schematic plan views illustrating two phases

  Referring to Figure 1, there is shown a blank of corrugated cardboard, cut and scored to present a strip 1, one end of which is provided on the one hand with a long-acting adhesive 2, covered with a protective tape 3 and, on the other hand, a very strong bead 4 of any type known to ensure the subsequent tearing of the strip 1, with a view to

  to open the closed container, as will be explained later.

  In contrast, the band I carries an end panel 5 from which it is differentiated by a transverse cutting line 6 (in one or more segments) and by two fold lines 7 situated between the longitudinal edges of the band I and two lateral longitudinal fold lines 8 defining protective flanges 9. In addition, the end panel 5 has a central longitudinal precut line 10, defining two flaps 11 and 12 opposite, holding the flanges 9 by the lines 8 and notched with two notches 13 facilitating their lifting After formation of this blank, glue 14 is arranged in two lateral longitudinal zones, then the end flap 5 is folded onto the band I according to the fold lines 7, which fixes permanently the flanges 9 to the band 1 and constitutes a blank available in the state and ready for use. In FIG. 3, it can be seen that to use the blank of FIG. 2, the two flaps II and 12 are lifted with the aid of the notches 13, in order to rotate them along the lines 8. The part of the band 1 which was under shutters 11 and 12 and which

  constitutes a base for receiving the objects to be packaged.

  According to the invention, a shim 20 is placed on the base 11 before disposing the objects on this shim 20. Here, the objects are compact disks each enclosed in a housing (this assembly will be referred to as "CD" in the following ) and fragile parts to be protected

  are the center and the corners, as explained above.

  This is why the shim 20 has a central oblong opening 21 and four cut sides 22 instead of the corners. In addition, it is notched at the mid-length of two notches

  triangular 23 equivalent to two sections cut opposite one another.

  A container of a given format can adapt to several different volumes, so that the same container can be used either for a single CD or for two sets juxtaposed, each one to four CDs. In total, the container of the same format can therefore receive from one to eight CDs by protecting them as effectively, what

whatever their number.

  Referring to Figures 4 and 5, there is the conditioning of a single CD designated A. It is placed on the shim 20, preferably in the middle of its length. Then, it is placed on it a second shim 30, identical to the shim 20, that is to say having an opening

  oblong 31 and four cut faces 32 instead of corners, and two notches 33.

  The openings 21 and 31 are necessarily in line with the center of the single CD

  A and their width is chosen to be a little higher than the fragile circular area.

  After having placed the second shim 30, the flaps 11 and 12 which fold over the shim 30 (FIG. 5) are folded down and then the band 1 is folded back on itself after having withdrawn the protective tape 3, so that the free end of the band I is fixed under the base the

  (Figure 6) to form the closed container ready to be shipped.

  It is understood that if the container receives shocks or pressure on its corners or its short sides, the protective edges 9 dampen and do not transmit to the inner CD. If the shocks or pressures are applied on the large faces of the closed container, they are not transmitted to the center of the CD since it is located at the bottom of the opening 21 or the opening 31, so that the constraints are received by the holds 20 and 30, and of course by the walls of the container itself, except for

the plumbs of the openings 21 and 31.

  The protective edges 9 protect the corners of the CDs well and the protection is further supplemented by the cut edges 22-32, but these protective edges 9 may be sufficient on their own, so that the cut edges 22-32 are optional, as

the notches 23-33.

  In order to maintain the flaps 11 and 12 folded while folding the strip 1, the wedge may be provided with an adhesive effect prolonged, covered with a protective tape that

  it is removed at the last moment (not shown).

  From the container of Figure 3, we can pack not one but several CDs in two groups juxtaposed because the dimensions of the container are chosen so that the width of the base 11, that is to say the distance that separates the two lateral fold lines 8, is sufficient to receive two CDs placed side by side. As the flaps 11 and 12 can be folded down to several levels, we can place up to eight CDs,

  in two groups of four, as shown in Figures 7 and 8.

  With this arrangement of CDs, the cut faces 22 and 32 are below and below

  the corners of the CDs closest to the sides of the container, while the notches 23 and 33 are below and above the corners of the CDs located one

against others.

  According to the same principle as above, the shocks and pressures applied to the container are transmitted neither to the centers of CDs through openings 21 and 31, nor corners of CDs

  thanks to the cut edges 21 and 22, and the notches 23 and 33.

  In fact, the most exposed corners of CDs are those that are closest to the sides of the container and not those that are placed against each other, so that the cut-off faces 22 and 32 are larger than the notches 23 and 33, which are optional.

  After closing the container of Figure 8, it leads to the container of Figure 6.

  The only difference between the closed container of Figure 5 and that of Figure 8 is its

  height which is lower for the first than for the second.

  In Figure 9, we see that we can also place in the container an odd number of CDs. The example shown is three CDs, two side by side placed on the hold 20 and one placed in the middle, on the two previous. It may be better to place a single

  CD in the middle of the lower hold 20 and two CDs above.

  In Figures 10 and 11, we see an example of a container whose flaps 11 and 12 are notched to present openings I la and 1 2a which have the same protective effect as

  the opening 31, so that this variant eliminates the upper shim 30.

  These are the shutters 11 and 12 themselves, constituting an intrinsic part of the container

which play the role of a wedge.

  After closing, the band 1 completely masks the ends of the flaps 11 and 12 folded down

  on the CDs as well as the CDs themselves.

  FIGS. 12 to 16 show a particular embodiment of the invention according to which a container with variable height is specially designed to receive two groups of CDs placed side by side and protected by a single shim 40 which adapts to all

  cases: two, four, six or eight CDs.

  The shim 40, preferably of corrugated cardboard because of its thickness and its elasticity, has two openings 41 and 42 situated on either side of a line of

folding 43.

  The distance Dl measured between one end of the shim 40 and the fold line 43 is

  substantially equal to the width of the base of the container which must receive the CDs.

  Both ends of the opening 41 are in an arc whose radius is slightly greater than that of the central zone to be protected CDs and the center of the circular arcs is on x and y axes on which are also the axes of the CDs after positioning. After straightening the flaps 11 and 12, the part of the wedge 40 which carries the opening 41 (FIGS. 13 and 15) is placed on the base and the shim 40 is folded along the line 43. CD (Figure 13) on this part of wedge in two groups juxtaposed. If there are only two (FIGS. 13 and 14), the other part of the shim 40 is folded over them, the length of which is calculated to extend over the entire width of the base la, and hence since strand 12

up to component 1 1.

  The length of the opening 42 is such that it lies directly above the two zones

  two CDs, as shown in Figure 14.

  Since the maximum number of CDs is two groups of four, ie eight in total, this case is represented in FIGS. 15 and 16. The same arrangements are found as in FIGS. 13 and 14, with the difference that the upper part of the hold 40 folded on the CD extends less far because its length is in the vertical part, the full height of four CDs, while this height was only that of a CD in Figure 13 But, here again, the opening 42 is in line with the central areas of the upper CDs. This situation is true for both extremes: a height of a single CD or a height of four CDs superimposed, we understand that it is also true for the cases

  intermediates with a height of two CDs and a height of three CDs.

  This embodiment therefore allows the packaging of two to eight CDs with a container

the same format.

  FIGS. 17 to 25 show the application of the invention to a container to

  variable height of a type other than that of the preceding figures.

  The blank of FIG. 17 comprises two parts 51 and 52 respectively determined by two cutting lines 53 and 54 located on either side of a fold line 55 by

  which the two parts 51 and 52 hold to each other.

  In addition, two cutting lines 56 and 57 are connected by an oblique fold line 58, and this structure makes it possible to pivot the part 52 on the part 51 and parallel to it, with the exception of a slight uplift, so that 'passing continuously through intermediate positions including those of Figures 18 and 19, we manage to arrange the part

  52 crosswise to Part 51.

  The portion 52 is marked with parallel fold lines in two groups 60 and 61 and these two groups are separated by a distance D2 substantially equal to the largest width of a CD case, while the width L of the part 52 is substantially equal

  at the smallest width of a CD case (Figure 19).

  A0 In other words, the area of the part 52 bounded by the two groups of crease lines and 61 constitutes a destination base 52a for the objects to be wrapped and, here, this base has

  substantially the same area as that of a CD case.

  Between the base 52a and the upper and lower edges of the portion 52, the fold line groups 60 and 61 define flaps 52b and 52_ equivalent to the flaps 11 and 12 of the flaps.

Figures I to 16.

  In the center of this base 52a, there is an opening 62 which could be circular since a CD can only be centered with respect to the base 52a. Here, this opening

62 is somewhat oblong.

  In Figure 20, we see a CD in place but it could be a single CD or two, three, or four CDs superimposed in a single group. In any case, the area

  center of the lower CD is in line with the opening 62.

  The flap 52c, which constitutes the equivalent of the flap 11 of the previous embodiment (FIG. 21), is then folded down on the upper CD and the protective tape 63 is removed.

  masked with long-acting adhesive 64, located on the flap 52k and this flap is folded down.

  above the previous one, which completely overlaps the top CD and fixes the 52k flap on

the flap 52c (Figure 22).

  Part 52 folds along a line of group 60 and a line of group 61 according to

  height of the CD or CDs arranged on the base 52_.

  According to this height, the two flaps 52k and 52c overlap more or less but an oblong opening 65 of the flap 521k and an opening 66 of the flap 52c opening on the lower side of the part 52, are superimposed in whole or in part but, in In all cases, the central zone of the single CD or the upper CD is opposite a 65 + 66 opening and is therefore protected against shocks or pressure exerted on the container.

closed.

  When the portion 52 is placed across the portion 51, it determines thereon two

51l and 51k panels.

  Thus, in order to finish the container, the panel 51k (FIG. 23) is folded down and the protective tape 63 is removed in order to unmask the prolonged effect adhesive 64 of the panel 5a, and then this panel 51a is folded onto the previous 51kb, which is attached to this one (figures 24 and). The panels 51a and 51b fold in one of the transverse fold lines provided in two groups 67 and 68, depending on the height of the objects to be packaged which here can be the height of one, two, three or four CDs superimposed. The total height (or length) of the portion 51 is set such that its upper end, the panel 51a,

  may always cover the lower end, the panel 51b, in whole or in part.

  It is observed that the folding lines of the groups 60 and 61 have a spacing which is coordinated with the width of the band 51, so that when the flaps 52b and 52c are folded,

  creates external protection edges 69.

  The closed container of Figures 24 and 25 is ready to be shipped by mail or courier. In Figures 26 to 29, there is shown a variant based on the same container as that of Figures 17 to 25, so that we will not repeat all the details given with respect to these figures. In order to simplify the understanding of this variant, the elements identical or equivalent, to the dimensions, of FIGS.

same references.

  The blank of FIG. 26 is equivalent to that of FIG. 17. It comprises two holding parts 71 and 72, the first part being wider than part 51 and the second part being larger

long as part 52.

  The reason is that here the container is intended to receive two groups side by side of CD, and no longer one, each group can comprise a single CD, or two,

three or four superimposed CDs.

  The base 72a of the portion 72, located between two groups of fold lines 60 and 61, has two circular openings 73 and 74 centered on the x and y axes of the CDs, whose position is well known. After two CDs have been placed on the base 72a (Figure

  27), their central zones are exactly in line with the openings 73 and 74.

  The flaps 72b and 72_ each have an oblong opening respectively 75 and

76.

  After folding the flap 72c (Figure 28) on the CDs, then the flap 72_ (Figure 29) partly on the CDs and partly on the flap 72c and attachment by the adhesive 64, the openings 75 and 76 are at the plumb the central areas of the higher CDs and protect them against

external aggression.

  Because the openings 75 and 76 are oblong, they are always placed next to the central areas of the CDs, while the flaps 72b and 72c folded overlap more

  or less depending on the height of the CDs arranged on the base 72a.

  The parts 51 and 52, as well as the parts 71 and 72, are arranged in such a way that the adhesive 64 and the protective tape 63 of the part 51-71 are exactly in line with those of the part 52-72, which allows their easy application during manufacture. With the two variants of FIGS. 17 to 25, on the one hand, and FIGS. 26 to 29, on the other hand, the wedges are formed by constituent elements of the containers themselves,

  so that no separate wedge is needed.

  This advantageous solution is possible each time the container has one or more parts from covering the wedge or shims. Here, the "lower" shim 52a - 72a is

  protected and isolated from the outside by the base la and the "upper" wedge 52b-52c and 722-

  72c is covered by the panels 51a-51b and 71a-71b.

  As already mentioned above, the cut edges and the notches to protect the corners of the CDs are optional when the container has protective edges

  This is the case here since both variants have flanges 69.

  This is why wedges, formed by constituent elements of

  containers themselves, do not have cut sides or notches.

  When the container is made of corrugated cardboard, the orientation of the grooves is not important for the implementation of the invention but may have for the facilities

Manufacturing.

  In particular, it is advantageous for the flutes to be perpendicular to the adhesive 64

  and ribbon 63 because these can then be applied to the waving machine itself.

  even. The oblong openings that have been described and shown may, in some cases, be replaced by several holes at most barlongs, that is to say, circular or square or even triangular, arranged in series and which are selectively in a good position according to the height of the packaged objects. This is particularly the case when the objects are all identical and thus vary the total height, according to their number, in equal steps

  to which corresponds the pitch of offset of the holes.
