Description

PACKAGING SYSTEM WITH INTERNAL PARTITIONING [0001] The invention relates to a packaging system consisting of an envelope such as a body made of semi-rigid material and partitioning elements of the interior volume of the body, for the packaging of objects having an elongated shape such as bottles.

Known corrugated boxes, for example for wine bottles, in which the box is parallelepiped rectangle with an internal structure in lockers. Thus, the user opens a face of the box, typically the upper face, and faces a partitioning of the interior volume in square section spaces opening on the lower and upper sides of the box, where the wine bottles are stored individually . The partitioning is based on a blank in three successive U-shaped sections whose intermediate flap is glued on an internal face of the body, and the other two flaps positioned parallel to one another partition the body in a main direction of it. Cross walls are furthermore placed perpendicularly to the partitioning shutters of the U-shaped blank, to form a structure called a cross 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 it is impossible to provide a box with a number of compartments that is not a multiple of 3.

Furthermore, to ensure that the partitioning elements remain in the place dedicated to them when the body is folded for empty transport, that is to say that the pairs of opposite side walls are rotated relative to each other in a coordinated manner, the ends of the transverse walls are glued by lugs dedicated to the inner surface of the body. But in the manufacturing process, it requires a second bond, 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, it is proposed a packaging system comprising a rectangular parallelepiped body and inserts for the partition of the interior volume of the body, for the packaging of goods in compartments individualized rectangular parallelepiped shape separated from each other within the body by internal walls, the body and the inserts being made of semi-rigid material. The box is formed by a folding of a main blank into five rectangular main panels arranged when the blank is flat with respect to each other successively in a reference direction, the first and the last of the five panels being sized to constitute together after their approximation, a side wall of the body, the second, third and fourth panels then constituting the other three side walls of the body, the fifth panel further bearing in its extension in the reference direction when the blank is flat, an extension of the main blank dimensioned to, being arranged parallel to the second and fourth panels, partition immediately the interior volume of the body into two parts, and the elements comprising at least one additional partition wall said main and at least one transverse partition wall, additional partition walls the main and transverse 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 the inside of the box, into said individual compartments of rectangular parallelepiped shape.

[0005] According to optional features:

- Said additional partitioning structure further comprises fastening means with pivoting of the wall (or the walls) of main partition (s) to a side wall of the box called wall attachment so that once the additional partitioning structure set up in the box, if the box is folded by coordinated pivoting pairs of side walls opposite to each other, the wall (or walls) of transverse partition (s) ) rotates (s) in a coordinated manner with the side walls facing the main partition wall (s) and the main blank extension at the first line (s) (s) crossing and the second (or) crossing line (s) to allow controlled folding of the additional partitioning structure in the interior volume of the body;

[0007] the added elements comprise two additional partition walls to complete the partitioning of the inside of the box on either side of the extension of the main blank, said two additional main partition walls being formed by folding a second blank of semi-rigid material in three successive sections, 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 pivotally fastening means for the additional partition walls main to the wall attachment;

- 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, thin slots for ensure the interlocking of the partition wall transverse vis-à-vis the additional wall of main partition;

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

- The extension of the main blank divides immediately in the main direction the internal volume of the body in two parts symmetrical with respect to the extension of the main blank, the partitioning of the interior of the body by the structure additional partitioning being also 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 in the number of 4, or the number of 5, but as mentioned above, there may be only one 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 each other and circled with a plastic strip.

The invention will be better understood, and other objects, features, details and advantages thereof will appear more clearly in the explanatory description which follows with reference to the accompanying 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 there is shown the blank 100 for constructing 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 flutes. It consists of a number of shutters, some of which are strictly rectangular, others approximately rectangular (trapezoidal) and of a more complex shape extension. 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 shutters, referenced shutters 1,2, 3, 4 and 5. These flaps are articulated to each other, each time by a rectilinear hinge formed by folding in the carton. Each of these shutters 1 to 5 is strictly rectangular. The shutters 2 and 4 have strictly the same dimensions, the shutters 1 and 5 can be folded together along the hinges and superimposed on a narrow strip for bonding to one another, to form a wall of the box having a identical dimension to that of the flap 3, thus forming the four side walls of the body (see Figure 4).

On the lateral sides of the main flaps 1 to 5 are secondary flaps that can be folded 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 shutters 2, 7 and 12, for shutters 3, 8 and 13, for shutter 4, 9 and 14 and for shutter 5, 10 and 15. 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 the central flaps 1 to 5 being slightly narrower than the side attached to the flap principal correspondent.

In known manner, the flaps 1 to 5, 6 to 10 and 11 to 15 make it possible to form a rectangular parallelepiped body by approaching the end of the flap 5 and the end of the flap 1 to form a face of the same dimension as the flap 3 opposite to that -this. The flaps 6 to 10 and subsequently 11 to 15 are folded to form a bottom and subsequently a cover for the body whose flaps 1 to 5 form the four lateral sides (see Figure 5, on which is observed the bottom which is closed, the lid 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 in 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 hinge hinge 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. Opposite the flap 5, the blank 100 comprises a strip 19 attached to the extension 16, extending parallel to the hinges between them separate the flaps 1 to 5 and the flap 5 of the extension 16, still articulated along a hinge parallel to the previous hinges formed by folding the blank. The band 19 extends, on one side, beyond the limit of the flaps 1 to 5 so as to be fixed, during the formation of the body, both against the (or on the surface of) shutter 3 and against the (or on the surface of) shutter 13.

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

The main partitioning element 200 consists of a blank of semirigid material, here again corrugated cardboard, for example micro-grooves, or flat cardboard, generally rectangular, and having 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 the flaps 201 and 203. The median between the two long sides of the shutter 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 one another 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 the flap 201 and also four in the flap 203. These slots 210 are lights in the surface of the blank, opening on both sides. They have a mouth on the side of the blank, and terminate 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 member 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 member 200, a slot 215 which extends from the edge inwards. Again, it 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 is slightly greater than 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, here 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 both sides), rectilinear and parallel to each other, among which in the center of the side a slot 310 wide and 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 and narrow at their end at the bottom. Their lengths are similar and close to half the width of the transverse partition elements 300.

FIG. 3 shows the formation of the partitioning element consisting of the main partitioning element 200 and the transverse partitioning elements 300. It is observed on the lower part of FIG. main partitioning 200 is U-folded with the flap 201 placed parallel to the flap 203, the slots 210 being placed in the figure upwards to face the transverse partitioning elements which are brought to be inserted into the slots 210, with which have coincided the slots 311. Thus, the two slots 311 of the partitioning element 301 are brought into coincidence with the first two slots 210 of the shutters 201 and 203, starting from the shutter 202. We put in place more in the second slots 210 of the shutters 201 and 203 the transverse partitioning element 302, in the third slots 210 of the shutters 201 and 203 the partitioning element 303 and in the fourth slots 210 of the shutters 201 and 203 the transverse partitioning element 304. Thus the four transverse partitioning elements are parallel to each other.

FIG. 4 shows 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 portions are interleaved. opposite, so as to stabilize the structure in 3 dimensions.

It has also been shown how this complex partitioning structure is introduced into the box formed using the blank 100. The box formed of the blank 100 is shown in the lower part of the figure. It can be seen that the shutters 1 and 5 have been brought closer to one another and glued by their respective edges overlapping on a small width so as to form a face of the box of dimension equal to the flap 3 to which it is attached. face, and that the extension 16 has been set up to partition in two equal halves the body, by sticking the band 19 on the inside of the flap 3 and on the inside of the flap 13 (not referenced for ease of reading, see also Figure 1).

The reported partitioning structure is brought by the top of the body which is open at this time both in the upper part and in the lower part. The slot 215 carried by the flap 202 and the slots 310 carried by the transverse partitioning elements 301 to 304 are placed opposite corresponding slots 17 in the extension 16. The adhesive is placed on the outer surface (opposite to the flaps 201 and 203) of the shutter 202 which faces the inner surface of the shutters 1 and 5, so as to fix the shutter 202 against the inner surface of the shutters 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 facility of adapted insertion.

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

In Figure 5 the box 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 constitute a bottom of the body. Thus, the crate can be loaded with the parts to be packed, such as glass bottles, earthen yoghurt pots, metal cylinders for industry, pharmaceutical product bottles, cylindrical ampoules. The walls between boxes prevent the products scratch or break clashing.

Figure 6 allows to view the partitioning from another angle. The potential pivoting zones of the different partitioning structures are also observed.

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

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

1.

Also the transverse partitioning element 301 is pivotable relative to the flap 203 around a hinge P2 constituted by the line defined by the slots which allowed the mutual engagement of the flap 203 and the element of transverse partitioning 301 (slots referenced 311 and 210 in Figure 3 in particular). A similar comment can be made for the pivoting of each transverse partitioning element 301 to 304 vis-à-vis each of the shutters 201 and 203.

Also we observe the possible pivoting between the transverse partitioning element 301 and the extension 16 about a pivot axis P3 defined by the slots that allowed the reciprocal nesting of the extension 16 and the transverse partitioning element 301 (slots referenced 310 and 17 in Figure 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 it should be noted the possible pivoting of the extension 16 relative to the face of the box defined by the flaps 5 and 1 around the hinge referenced PO constituted by the common edge of separation between the extension 16 and the flap 5 (a fold in the carton of the 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 band 19, referenced P4. The hinge is held at the wall 3 by means of the band 19 which is bonded to the wall 3.

In Figure 7 there is shown the pivoting mentioned above in progress, by folding the body, empty for storage purposes thereof. This involves tilting the inner face of the flaps 1 and 5 on the inner face of the flap 4 and the inner face of the flap 2 on the inner face of the flap 3. The pivoting takes place within the blank 100 between the flaps 1 and 2, between which the angle widens, between the flaps 2 and 3 between which the angle decreases, between the flaps 3 and 4 between which the angle widens and between the flaps 4 and 5 between which 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 band 19.

In Figure 8 are shown the corresponding movements occurring within the reported structuring elements. 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, in which the partitioning elements are folded in a coordinated manner, thanks to the previous elements. The box can be stored and stacked and packaged in groups, for example fifteen boxes with strapping plastic strapping.

FIG. 10 shows an embodiment similar to the previous one 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 members. side flaps to accommodate the corresponding transverse partitioning elements 3000.

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

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