Description

The invention relates to a packaging system consisting of an envelope such as a box made of semi-rigid material and elements for partitioning the interior volume of the box, for the packaging of 'elongated objects like bottles.

Corrugated cardboard boxes are known, for example for wine bottles, in which the box is rectangular parallelepiped with an internal structure in racks. Thus, the user opens one side of the case, typically the upper side, and faces a partitioning of the interior volume into spaces of square section opening onto the lower and upper sides of the case, where the wine bottles are stored individually. . The partitioning is based on a blank in three successive flaps arranged in a U, the intermediate flap of which is glued to an internal face of the box, and the other two flaps positioned parallel to each other partition the box in a main direction of it. Transverse walls are also placed perpendicular to the partitioning flaps of the U-shaped blank, to form a structure called a crosspiece which defines compartments with a square section in a number which is a multiple of 3. This constitutes a first difficulty, since it is then impossible to supply a box with a number of compartments which is not a multiple of 3.

Furthermore, to ensure that the partitioning elements remain in the place dedicated to them when the box is folded for empty transport, that is to say that the pairs of opposite side walls are pivoted one with respect to the other in a coordinated manner, the ends of the transverse walls are glued by lugs dedicated to the internal surface of the box. However, in the manufacturing process, this requires a second bonding, in addition to that of the intermediate flap of the U-shaped blank. This is expensive, and complicated to industrialize.

To solve the problems thus defined, a packaging system is proposed comprising a rectangular parallelepiped box and added elements for partitioning the interior volume of the box, for packaging goods in individual compartments of rectangular parallelepiped shape. separated from each other within the body by internal walls, the body and the added elements being made of semi-rigid material. The box is formed by folding a main blank into five rectangular main panels arranged when the blank is flat relative to each other successively in a reference direction, the first and last of the five panels being sized to constitute together after their approximation, a side wall of the box, the second, third and fourth panels then constituting the other three side walls of the box, the fifth panel bearing further in its extension in the reference direction when the blank is flat, an extension of the main blank dimensioned for, being arranged parallel to the second and fourth panels, to immediately partition the interior volume of the body into two parts, and the added elements comprising at least one additional partition wall called the main partition and at least one transverse partition wall, the additional partiti walls main and transverse on being cut so as to form, once nested together by at least a first crossing line, an additional partitioning structure to be nested by at least a second crossing line with the extension of the main blank to complete the partitioning from inside the box, in said individual compartments of rectangular parallelepiped shape.

According to optional characteristics:

- Said additional partitioning structure further comprises means for fixing with pivoting of the wall (or walls) of main partition (s) to a side wall of the box known as fixing wall so that once the additional partitioning structure put in place in the box, if the box is folded by coordinated pivoting of pairs of side walls opposite one another, the wall (or walls) of transverse partition (s ) pivot (s) in a coordinated manner with the side walls opposite the main partition wall (s) and the main blank extension at the first line (s) (s) crossing and (or) second (s) line (s) crossing to allow controlled folding of the additional partitioning structure in the interior volume of the box;

- The added elements include two additional main partition walls to complete the partitioning of the interior of the box on either side of the extension of the main blank, said two additional main partition walls being formed by folding of a second blank of semi-rigid material in three successive flaps, the first and third flaps of which constitute the two additional main partition walls and the second is a surface for bonding to the fixing wall constituting the fixing means with pivoting for the additional main partition walls to the fixing wall;

- The first crossing line is defined by wide slots to guide the engagement of the transverse partition wall vis-à-vis the additional main partition wall and, at the end of engagement, fine slots for ensure the interlocking of the transverse partition wall vis-à-vis the additional main partition wall;

- The second crossing line is defined at least by wide slots to guide the engagement of the transverse wall with respect to the extension of the main blank;

- The extension of the main blank immediately partitions in the main direction the interior volume of the body into two symmetrical parts with respect to the extension of the main blank, the partitioning of the interior of the body by the structure additional partitioning also being symmetrical with respect to the extension of the main blank;

- The extension is fixed, for example by gluing, to the third panel, at its end opposite to the fifth panel;

The transverse partition walls are in the examples presented 4 in number, or 5 in number, but as mentioned above, there may be only a single transverse wall;

- The semi-rigid material is a corrugated cardboard, or a flat cardboard (a compact cardboard), or a semi-rigid synthetic polymer material.

The invention also relates to a batch of packaging systems according to the principles mentioned above, in which the packaging systems are folded, stacked on top of each other and strapped with a plastic strip.

The invention will be better understood, and other objects, characteristics, details and advantages thereof will appear more clearly in the explanatory description which follows, made with reference to the appended drawings given solely by way of example illustrating a embodiment of the invention and in which:

- Figures 1 to 9 are views of a first embodiment of the invention;

- Figures 10 and 11 are views of a second embodiment of the invention.

In Figure 1 is shown the blank 100 for building a box according to a first embodiment of the invention. The blank 100 is made of a semi-rigid material, here corrugated cardboard, for example single or double grooves. It is made up of a number of shutters, some of which are strictly rectangular, others approximately rectangular (trapezoidal) and of an extension of more complex shape. The blank 100 extends over a main rectilinear direction (direction of development of the flat blank, from left to right in the figure) along which follow five main flaps, referenced flaps 1,2, 3, 4 and 5. These flaps are hinged to each other, each time by a straight hinge formed by folding in the carton. Each of these sections 1 to 5 is strictly rectangular. The flaps 2 and 4 are strictly the same dimensions, the flaps 1 and 5 can be brought together by folding along the hinges and superimposed on a narrow strip for bonding to each other, to form a wall of the box having a identical dimension to that of shutter 3, thus forming the four side walls of the box (see Figure 4).

On the lateral sides of the main flaps 1 to 5 are secondary flaps which can be folded down along the corresponding side of the associated main flap. This side of the main flap, common with a side flap, defines a new hinge, obtained by folding in the semi-rigid material. These side flaps for shutter 1 are referenced 6 and 11, for shutter 2, 7 and 12, for shutter 3, 8 and 13, for shutter 4, 9 and 14 and for shutter 5, 10 and 15. The shape of these side flaps 6 to 10 and 11 to 15 is close to a rectangular shape, but is slightly trapezoidal, the side of each of these side flaps opposite to the central flaps 1 to 5 being slightly narrower than the side attached to the flap main correspondent.

In known manner, the flaps 1 to 5, 6 to 10 and 11 to 15 make it possible to form a rectangular parallelepiped box by bringing the end of the flap 5 and the end of the flap 1 together to form a face of the same dimension as the flap 3 opposite to that -this. The flaps 6 to 10 then later 11 to 15 are folded to form a bottom and subsequently a cover for the box, the flaps 1 to 5 of which form the four lateral sides (see FIG. 5, on which the bottom which is closed, the cover remaining open).

However the blank 100 also has in the extension of the flap 5 opposite the flaps 1 to 4 when it is flat (Figure 1), an extension 16 cut from an additional flap of the blank 100 extending the flaps 1 to 5, articulated to the flap 5 by a hinge formed by folding the blank, parallel to the articulation hinges of the flaps 1 to 5. The extension 16 has in particular, on its side corresponding to the flaps 11 to 15 (cover side), slots 17 generally parallel to the hinges separating the flaps 1 to 5, and flared towards the side of the extension 16 corresponding to the flaps 11 to 15. Unlike the flap 5, the blank 100 has a strip 19 attached to the extension 16, extending parallel to the hinges which separate between them the flaps 1 to 5 and the flap 5 of the extension 16, further articulated along a hinge parallel to the preceding hinges formed by folding the blank. The strip 19 extends, on one side, beyond the limit of the flaps 1 to 5 so as to be fixed, during the formation of the box, both against the (or on the surface of) flap 3 and against (or on the surface of) flap 13.

Figure 2 shows the partitioning elements of the interior volume of a rectangular parallelepiped box such as that which is formed with the blank of Figure 1. These partitioning elements consist on the one hand of an element main partitioning 200 and on the other hand a series of four transverse partitioning elements 300.

The main partitioning element 200 consists of a blank made of semi-rigid material, here again corrugated cardboard, for example with micro-grooves, or even flat cardboard, generally rectangular, and comprising three hinged flaps succeeding one another. in a main direction, including a first rectangular flap 201 articulated on its short side with a rectangular flap 202 which in turn is articulated on its two long sides with flaps 201 and 203. The median between the two large sides of flap 202 constitutes an axis of symmetry for the whole of the main partition element 200 when it is flat. Thus, the flaps 201 and 203 are symmetrical to each other with respect to the median of the flap 202.

On one of the long sides of the main partition element 200, slots 210 are present parallel to the hinges separating the flaps 201 and 202 on the one hand and 202 and 203 on the other hand. These slots are referenced 210 and are four in number in the shutter 201 and also four in the shutter 203. These slots 210 are openings in the surface of the blank, opening onto its two faces. They have a mouth on the side of the blank, and end opposite this mouth by a tight portion. They have a length between the mouth and the end of the tight end, which is slightly less than half the width of the main partition element 200.

On the other side of the main partition element 200, there is at the median between the two hinges of the flap 202, which is the axis of symmetry of the partition element 200, a slot 215 which extends from the edge inwards. Again, this is a light in the surface of the blank, opening on both sides. This slot 215 is essentially a wide slot over its entire length, from its mouth on the side to its bottom. It has a length that slightly exceeds half the width of the main partition element 200.

The transverse partition elements 300 are identical and referenced 301, 302, 303 and 304. Each of them is a rectangle of semi-rigid material, again cardboard identical to the cardboard of the main partitioning element 200 On one of the long sides are three slots (always lights in the surface of the cardboard, opening on its two faces), rectilinear and parallel to each other, among which in the center of the side a slot 310 wide and of constant width on its entire length, and on either side of this slot 310 symmetrically two slots 311 wide at the mouth on the side then narrow at their end at the bottom. Their lengths are similar and close to half the width of the transverse partition elements 300.

In Figure 3 is shown the formation of the partitioning insert consisting of the main partitioning element 200 and the transverse partitioning elements 300. It can be seen in the lower part of Figure 3 that the element of main partition 200 is folded into a U with the shutter 201 placed parallel to the shutter 203, the slots 210 being placed in the figure upwards to face the transverse partitioning elements which are brought to be inserted in the slots 210, with which made the slots 311 coincide. Thus, the two slots 311 of the partitioning element 301 are brought into coincidence with the first two slots 210 of the flaps 201 and 203, starting from the flap 202. In addition, the second slots 210 of the flaps 201 and 203 the transverse partitioning element 302, in the third slots 210 of the flaps 201 and 203 the partitioning element 303 and in the fourth slots 210 of the flaps 201 and 203 the transverse partitioning element 304. Thus the four transverse partitioning elements are parallel to each other.

In Figure 4 is shown the partitioning structure resulting from the nesting of the main partitioning elements 200 and the transverse partitioning elements 300. The slots 311 and 210 are engaged with each other until the narrow parts overlap. opposite, so as to stabilize the structure in 3 dimensions.

There is also shown how this complex partitioning structure is introduced into the box formed using the blank 100. The box formed from the blank 100 is shown in the lower part of the figure. We see that the flaps 1 and 5 have been brought together and glued by their respective edges which overlap over a small width so as to form a face of the body of dimension equal to the flap 3 to which it forms face, and that the extension 16 has been put in place to partition the body into two equal halves, by gluing the strip 19 on the inside of the shutter 3 and on the inside of the shutter 13 (not referenced for easier reading, see also figure 1).

The attached partitioning structure is brought from the top of the box which is at this stage open both in the upper part and in the lower part. The slot 215 carried by the shutter 202 and the slots 310 carried by the transverse partitioning elements 301 to 304 are placed opposite corresponding slots 17 in the extension 16. Glue is placed on the external surface (opposite the shutters 201 and 203) of the flap 202 which faces the internal surface of the flaps 1 and 5, so as to fix the flap 202 against the internal surface of the flaps 1 and 5. The slots 310 and 17 are engaged reciprocally, but as they are wide, the nesting is done with a game offering a suitable ease of insertion.

We see in Figure 5 the result of this process. The box now has a partition into 5 x 4 spaces of identical sizes. In the longitudinal (main) direction, the partitioning is carried out successively by the transverse partitioning elements 301 to 304, while in the transverse direction, the partitioning is carried out successively by the flap 203, the extension 16, and the flap 201.

In Figure 5 the body is shown closed in the lower part since the flaps 6 to 10 are no longer visible, because they have been pivoted in a conventional manner so as to form a bottom of the body. Thus, the case can be loaded with the parts to be packaged, such as glass bottles, earthenware yoghurt pots, metal cylinders for industry, bottles of pharmaceutical product, cylindrical ampoules. The walls between boxes prevent the products from scratching or breaking when they collide.

Figure 6 allows to view the partitioning from another angle. We also observe the potential pivot zones of the different partitioning structures.

In particular the flap 203 is capable of being pivoted relative to the face of the body formed by the flaps 1 and 5, around a hinge P1, formed by the hinge between the flaps 202 and 203 glued, by the shutter 202, to the shutter 5. A similar comment can be made for the pivoting of the shutter 201 relative to the face formed by the shutters 1 and

5. The hinge is the articulation between the flaps 202 and 203 glued, by the flap 202, to the flap

1.

Also the transverse partitioning element 301 is capable of pivoting relative to the flap 203 around a hinge P2 formed by the line defined by the slots which have allowed the mutual nesting of the flap 203 and the element of transverse partitioning 301 (slots referenced 311 and 210 in particular in Figure 3). A similar comment can be made for the pivoting of each transverse partitioning element 301 to 304 with respect to each of the flaps 201 and 203.

We also observe the possible pivoting between the transverse partitioning element 301 and the extension 16 around a pivot axis P3 defined by the slots which have allowed the reciprocal nesting of the extension 16 and the transverse partitioning element 301 (slots referenced 310 and 17 in FIG. 4 in particular). A similar comment can be made for the pivoting of each of the transverse partitioning elements 301 to 304 with respect to the extension 16.

Also note the possible pivoting of the extension 16 relative to the face of the body defined by the flaps 5 and 1 around the hinge referenced PO formed by the common separation edge between the extension 16 and flap 5 (a fold in the carton of blank 100). There is also a possible pivoting between the extension 16 and the wall 3 of the body, around the hinge between the extension 16 and the strip 19, referenced P4. The hinge is held on the wall 3 by means of the strip 19 which is glued to the wall 3.

In Figure 7 there is shown the pivot mentioned above during production, by folding the box, empty, for storage purposes thereof. This involves tilting the internal face of the shutters 1 and 5 on the internal face of the shutter 4 and the internal face of the shutter 2 on the internal face of the shutter 3. The pivoting takes place within the blank 100 between the shutters 1 and 2, between which the angle widens, between flaps 2 and 3 between which the angle decreases, between flaps 3 and 4 between which the angle widens and between flaps 4 and 5 between which the angle decreases. In addition, the extension 16 pivots around the hinge PO so that its angle with the flap 1 decreases and its angle with the flap 5 widens. A similar movement is observed at the end of the extension 16 corresponding to the strip 19.

In Figure 8 are shown the corresponding movements occurring within the reported structuring elements. A pivoting takes place around the hinge P1 between the flap 203 and the flap 202, a pivoting takes place between the transverse structuring element 301 and the flap 203 around the hinge P2 and a pivoting takes place between the extension 16 and the transverse partitioning element 301 at the hinge P3.

In Figure 9 there is shown the completely flattened box, within which the partitioning elements are folded in a coordinated manner, thanks to the previous elements. The box can be stored and be stacked and packaged in groups, for example fifteen boxes with strapping by plastic strap.

- In Figure 10 there is shown an embodiment similar to the previous but involving a set of transverse partitions 3000 comprising five successive elements parallel to each other and a main partitioning element 2000 having five successive slots on each of its side flaps so as to accommodate the corresponding 3000 transverse partitioning elements.

The box resulting from the shaping of the blank 1000 comprises an extension 160 integrated partitioning also having five slots to accommodate the five transverse partitioning elements 3000. This results as shown in Figure 11 a case containing 6 x 4 = 24 boxes to accommodate bottles or other items to be packaged.

The invention is not limited to the embodiment presented but extends to all variants within the scope of the claims.
