Description

The present invention relates to corrugated cardboard packaging boxes comprising side walls, and a bottom, at least one side wall being made of corrugated cardboard packaging boxes comprising side walls, and a bottom, at least one side wall being provided with at least one stacking post and the bottom being provided with a corresponding recess.

It also relates to cuts or sets of blanks for the constitution of such boxes. It finds a particularly important application, although not exclusive, in the field of stackable crates on pallets, provided with stacking tenons requiring several manipulations especially during depaletization phases. Box and tenon type stacking systems are already known, the tenon being vertical and rectangular and arranged to cooperate with a corresponding recess of complementary rectangular shape, making it possible to avoid lateral sliding. Such systems are certainly blocking but hard to disconnect when trying to lift the boxes from one side of the latter. They are also fragile and do not resist repeated manipulation. It is also known (FR-A-2.311.717) packaging whose lid is formed of flaps some of which are complementary in shape to that of indentations formed in the bottom also formed 3025785 2 flaps, allowing a recess and therefore a lateral blocking. In addition to such an embodiment imposing a form of flap double flaps, it is not suitable for the low basis weight and does not always allow a perfectly vertical stacking, due to shifts that may exist during the formation of the body . Also known is a box with a tab cap for example taken in the side walls and glued on the upper face thereof by folding around the fold line between walls and flaps. If such a box allows a good centering and forms a blockage, solid and not very fragile, its design generally leads to a weakening of the walls and may be insufficiently blocking in the event of shocks to excessive lateral stresses. The present invention aims to overcome these drawbacks and, to this end, to provide a box, a blank and a set of blanks which better than those previously known to meet the requirements of the practice, in particular in that it proposes a solution allowing to easily guide and release the tenons of the boxes during unstacking, in particular from a lateral side of the stack without the risk of tearing off the side of the box seized by the operator. The invention thus facilitates unstacking in particular of cardboard plate of low grammage while maintaining excellent lateral locking and holding boxes on top of each other during palletizing.

3025785 3 It also allows a simple and inexpensive box formation and is not limited to boxes with lid, but is instead particularly advantageous for the trays.

With the invention it will therefore be possible to prevent slippage of packages when stacked on top of each other during their palletization as well as to use light weights (less than 150 g / m2), while allowing an excellent release and disconnection of the packages between them without risk of damaging them. The configuration of the boxes also allows an optimized load descent of the upper boxes on the lower boxes, allowing excellent centering of the walls one above the other. For this purpose, the present invention proposes in particular a corrugated cardboard packaging box comprising side walls and a bottom, at least one side wall being provided with at least one stacking post and the bottom being provided with a recess. corresponding, characterized in that each tenon is substantially rectangular trapezoidal shape comprising a sloping side side and the other right side at least in the lower part, and in that each corresponding recess is formed of a first rectangular recessed area in the bottom of the box and a second adjacent triangular area recessed into the adjacent side wall, the junction zone 30 between bottom and side wall adjacent to the end of said rectangular and triangular recessed areas, forming a triangular crushed wedge obliquely by bottom ratio, to constitute a guide rail 3025785 4 for embedding or ejection of the pin of a box from below.

Figs. 7A to 7C are plan views of cutouts for tray with cap in accordance with other embodiments of the invention. Figures 8A to 8C show the steps of disengaging two recessed boxes according to the invention.

Figure 1 shows a corrugated cardboard tray 1 according to a first embodiment of the invention. It comprises four rectangular side walls, namely two transverse walls 2, 2 'and two longitudinal walls 3, 3', facing each other in pairs, connected to a rectangular bottom 4 and orthogonal thereto. The longitudinal walls 3, 3 'each comprise a lower edge 5 connected to the bottom by a first fold line, and an upper edge 6 provided with two stacking tenons 7. The lower edges 5 are provided with corresponding recesses 8 and located in law of tenons. In the rest of the description, the same reference numbers will be used to designate identical or similar elements. FIG. 2 is a plan view of the blank 9 making it possible to obtain the plate 1 of FIG. 1. This plate comprises the central panel 4 forming the bottom, connected on each side to two rectangular lateral panels 3, 3 ' forming said longitudinal side walls, symmetrical with respect to a longitudinal central axis 10, via the first fold lines 11.

Each of the side panels 3, 3 'is further connected at each of its ends, respectively to a rectangular or square flap 12 by second fold lines 13.

The central panel 4 is also connected on its two other sides to the two panels 2, 2 'forming the transverse walls, by third fold lines 14 in a manner known per se. According to the embodiment of the invention more particularly described here (see also FIG. 2A), the upper edges 6 have tenons 7 of substantially trapezoidal rectangle shape, including a first lateral side 15 sloping towards the outside of the tenon 7, ie forming an angle α with respect to the upper edge 6 of between 10 ° and 45 °, for example 30 ° and is of a first determined length d for example between 1 cm and 3 cm. On the opposite side, the pin 7 has a second lateral side 16, substantially perpendicular to the corresponding upper edge 6, at least on a portion 17 adjacent thereto (at the bottom). More precisely, the second lateral side 16 connects the large base 18 of the tenon, aligned with the edge 6, and the small outer base 19, of the trapezium. It comprises, in the outward extension of the portion 17, a bevel or cut 20 at the top, to facilitate embedding. The length of the large base 18 is L (for example 5 cm) and that of the small base 19 1 (including the beveled portion) (for example 3 cm), the height of the trapezium formed by the post being h (for example 1 cm).

The recess 8 corresponding to the pin comprises meanwhile a first recessed area 21 rectangular, elongated in the longitudinal direction, ie parallel to the first fold line 5 11, formed in the bottom 4. It is d a length Ia, for example between 1 and 7 cm, for example between 2 and 5 cm, and is of a width x, for example between 0.4 and 1.5 cm, for example between 0.7 and 1.2 cm, with the equal to 1 to 1 or substantially equal (a little less than 1, for example less than 0.1 cm to facilitate embedding). The first rectangular recessed zone 21 thus comprises two longitudinal sides 22, 23, namely a first outer side 22 of length 1, and a second side 23 coinciding on a first portion of its length 1 with the first folding line 11. recess 8 also includes a second triangular recess area 24 adjacent to an end portion 25 of the first zone 21. In other words, the recess 8 straddles the first fold line 11, with a rectangular zone 21 on one side on the bottom 4, and a triangular zone 24 on the other side on the adjacent longitudinal panel 3 '. The triangle constituting the second recessed zone 24 is rectangle and advances to a vertex A in the panel 3. A side 26 of the rectangle of the triangle (from the vertex A) is aligned with a transverse side 27 of the first rectangular zone, the other side (fictitious) of the right triangle being on the extension of the fold line 11.

The hypotenuse 28 of the second triangular recess zone 24 connects the vertex A and an intermediate end B on the second longitudinal side 23 of the rectangular zone 21 (situated on the first fold line), so that the first and second regions of the recess form a single hole straddling the line 11. According to the invention, a triangular junction zone 29 between bottom and sidewall formed of corrugated cardboard is provided to form a crushed wedge . It is delimited by two fourth fold lines 30, 31 starting from a point C situated on the first fold line 11 in line with the vertex D formed at the end of the slope or first lateral side 15 of the trapezium of the tenon 7 located on the edge 6, and corresponding to the recess 8. The junction area 29 thus forms a triangle between the ends A and E of the lateral side of the recess 8 formed by the first and second recessed areas screwed to screw, transversely to the recess area 8, and the top C. It is adapted to form a triangular crushed wedge secured to the bottom of one side and the wall of the other, obliquely to the bottom, for 25 constitute a guide ramp for embedding or ejection of the tenon of the top plate opposite the recess area 8, as described more specifically below with reference to Figures 8A to 8C.

Thus, when a first plate is formed, (see FIGS. 3A and 3B), the pin 7 can be inserted into the corresponding recess 8 of a box or plate stacked on the first plate, the triangle of the zone 3025785. junction 29 taking (during the formation of the plate) a plane direction oblique with respect to the bottom 4 and the wall 3 'to form a crushed wedge. It thus forms a tetrahedron whose top C 5 is on the first fold line and whose base AE is oblique and extended by the first rectangular recessed area. In other words, the inner face 32 of the junction zone 29 (crushed wedge) of the tetrahedron then forms a sloped plane and constitutes a guide ramp for embedding or ejecting the post 7 of a recessed tray below. . More specifically, during the insertion, the first sloping lateral side 15 of the post 7 abuts against the face 32 and is guided vertically by it. The pin 7 is also guided by the lateral side of the rectangular zone 21 against which the second lateral side 16 of the tenon 7, 20 rubs until it comes into permanent abutment against the first transverse lateral side of the recess. The post 7 is then blocked by the upper edge of the recess and by the bottom 4 of the stacked tray on it.

The tray 1 is therefore properly held in place during its movements. FIGS. 4A to 7C show several embodiments of blanks for boxes or trays according to the invention.

In the embodiments shown in FIGS. 4A-4D, each plate comprises four pins 7 and four recesses 8 respectively divided in pairs on the upper edges 30 and on the first fold lines 11 of the trays. Thus, with reference to FIG. 4A, the cutout has a center of symmetry 33, the tenons 7 and 5 recesses 8 being then formed by symmetry with respect to the center 33. In FIG. 4B there is a longitudinal symmetry with respect to the longitudinal axis 34 of the blank, and in FIG. 4C a transverse symmetry with respect to the transverse axis 35. In FIGS. 4A to 4C the assembly formed by the four pairs of tenons / recess is centered vertically, leaving for each pair an average distance y equals between the second folding line 14 closest to the pair considered and said pair. Figure 4D shows an arrangement 36 for simultaneously obtaining two identical staggered cuts, to form two trays to limit cardboard falls. Here, the tenon 7 / recess 8 pairs are not centered or symmetrical, leaving a distance a between the second fold line 14 and a first pair 37 smaller than the distance b between a second pair 38 and the corresponding fold line. on the other side. The first and second cutouts being arranged head to tail relative to each other this allows a saving of cardboard.

FIG. 4E shows another embodiment of cutting 39 according to the invention for the formation of a curb plate. Here, the cut-out is generally similar to that of FIG. 4A, on the one hand that the transverse walls 2, 2 'are substantially T-shaped, whose outer edge of the horizontal bar of the T coincides with the second fold line 14 and secondly that it further comprises on each side of the longitudinal panels 3, 3 'a rectangular flap 40 to which it is connected by a fifth fold line 41 parallel to the first fold lines. Each fifth fold line, has two discontinuities 42 forming a tenon cut on its periphery, (except on its large base). The rectangular flaps 40 form sidewalks for the formed plate and comprise, in a manner known per se, a flap 43 for gluing articulated at each of their longitudinal ends. Figures 5A-7C show embodiments according to the invention for cardboard boxes comprising a bottom and a cap.

Figs. 5A and 5B show cutouts for forming boxes comprising a sequence of four main flaps 44, 45, 46, 47 terminated by a fold tab 48. The main flaps and the gluing tab 25 are interconnected by first folding lines 49, 50, 51, 52. Two of the non-adjacent main flaps (44, 46, FIG. 5A, or 45, 47 FIG. 5B) form the bottom and the cap of the box, the two other flaps forming two first ones. side walls vis-à-vis when the box is formed. The flap assembly is provided on one side with a first set of flaps and on the other side with a second set of flaps 54 for forming part of the side walls. In FIG. 5A, the recesses 8 are formed on one of the first fold lines 50 of one of the five principal shutters 45 forming the bottom 4. The tenons 7 are in turn formed vis-à-vis on the first line of opposite folding 51 of the adjacent flap 46 and in the corresponding adjacent flap 47. In FIG. 5B, successively on the upper edge 6 of the flap 44 on the one hand, and on the first folding lines 49 to 52 on the other hand, there is a first pair of tenons 7 and then, on the first fold line 49 a corresponding pair of recesses 8, on the next fold line 50 another pair of recesses 8, and finally on the next fold line 51 of the flap 46, a second pair of corresponding tenons 7. Recesses 55 in the tongue 48 for bonding are also provided to pass the tenons 7 of the flap 44. In summary, the recesses 8 and the tenons 7 are formed in the flaps at the first fold lines and / or the edge 6 external devoid of flap of the suite.

The tenons 7 of the first pair of tenons 7 are for example of a height greater than that of the second pair, or rests on a rectangular base between the upper edge and them. Thus the thickness of the cardboard they pass through is compensated 30 and this offers a post 7 of the same retention capacity on one side and the other of the box. In the embodiments of FIGS. 6A and 6B, the blanks comprise a series of four rectangular flaps 56, 57, 58, 59 with gluing tab 60, provided with two sets of flaps 61, 62 connected on both sides. other flaps thereof by junction lines 63, 64. Here the tenons 7 and 5 recesses 8 are respectively located on the lines 63, 64 of junction with the flaps, and the bottom 4 and the cap being formed by and in the flaps at said junction lines. In FIG. 6A, the tenons 7 and recesses 8 10 are formed on either side of the same flap 58. In FIG. 6B, two non-adjacent flaps 56 and 58 comprise the tenons 7 and recesses 8. FIGS. 7A at 7C show three sets 65, 66, 67 of two blanks (70, 71; 72, 73 and 74, 75) for forming a box according to other embodiments of the invention. The box is formed from two blanks made of corrugated sheet material, namely a first blank (70, 72, 74) adapted to form a tray for the bottom 4 of the box and a second blank (71, 73 , 75) suitable for forming the cap with upper face 76 of said box. In the embodiments of FIGS. 7A and 7B, the first cutout 70, 72 comprises the pegs 7 or the recesses 8 and the second cutout comprises the recesses 8 or the corresponding pegs 7 on the corresponding fold lines. The first cutouts forming the bottoms 4 are similar to that described in FIG. 2 but differ in that it comprises only lugs 7 or recesses 8. The second cutout forming the cap is formed by a main flap 76 connected 3025785 19 longitudinally to first flaps 77 by first fold lines 78 and transversely to second flaps 79 by second fold lines 80.

In FIG. 7A, the first cutout 70 comprises, formed in the central panel 4 and on either side of its second fold lines 82, two tenons 7 on each of the latter. The cap has four recesses, divided by two on each first fold line 83 of the second cut. In Fig. 7B, the locations of the pegs and recesses are permuted and the pegs are formed in the main flap 76 of the second cut. In FIG. 7C, the first cutout is similar to that described in FIG. 2. The second cutout has meanwhile and at a location located vertically above the tenons 7 and in the main flap 76 rectangular openings 84 of FIG. length and width adapted to let the pins 7 through them. The operation of the stacking according to the invention will now be described more particularly with reference to FIGS. 8A to 8C. In FIG. 8A, a first plate 85 is superposed and stacked on a second plate 86. The tenons 7 of the second plate 86 are then locked in the recesses 8 corresponding to the first plate 85, the recess then forming a mortise. In Fig. 8B a vertical force (Arrow 87) is applied, for example by an operator, to one end 88 of the first plate.

The first upper plate 85 is thus raised at the origin of the force applied, and then releases the pin 7 of the second lower plate 86 of the considered side.

On the other side, the slope of the first lateral side 15 of the post 7 presses and pivots slightly by sliding on the junction zone and / or on the second lateral side of the corresponding recess 8. A longitudinal and oblique force 89 is then exerted (see FIG. 8C) on the plate by the operator pulling the first plate towards him. The pin 7 slides on the other side in the longitudinal direction along the rectangular recess 8 and the face of the crushed wedge forms a guide ramp 15 while exerting a force in the direction transverse to the tenon. The transverse force then tends to move said tenon when the pin is no longer held vertically by the side wall of the first upper plate. When the tenon slides until its right edge exceeds the first portion of the rectangular area of the corresponding recess, the tenon is then ejected outside the plate on the other side of the side wall of the top plate. . The beveling of the right edge facilitates said ejection by avoiding the retention of the right edge by the second lateral side of the recess of the upper plate. Depalletization is thus greatly facilitated. It goes without saying, and as it follows from the foregoing, the present invention is not limited to the embodiments more particularly described.

On the contrary, it encompasses all the variants and in particular those in which the tenons are positioned on another wall than those forming the outer walls of the box, like an internal stiffening panel.
