- the main flaps 115 and 116 are open and apart towards the outside as shown in FIG. 4.
- Each group is formed of two rows X lt X 2 (respectively X 3 , X 4 ) of three pots pu, which amounts to the same thing, of three rows Y ] _, Y 2 and Y 3 of two pots.
- the pots are lowered by inserting the walls between the rows X ⁇ _ and X 2 on the one hand, X3 and X 4 on the other hand, each group thus being astride a wall.
- the tabs 132, 133 and 134, 134 also find their place simultaneously in the recesses 163 arranged between a group of four yoghurt pots.
- the upper ply constituted in an identical manner to the first ply, is then placed on the lower ply, the rounded end of the tabs allowing in particular guidance and setting of the positioning of this second ply relative to the first.
- the secondary flaps are also glued before folding the main flaps 115 and 116 onto the lid of the yogurt pots of the upper layer.
- the secondary flaps are then applied one against the other, centering them one with respect to the other thanks to the elongated recesses 156, which are adjusted one opposite the other, for example with a spreader finger applied in the direction of the slot in the recess.
- This flat projecting part is located to the right of the junction slot between the rows Y j and Y 2 and to the right of the notches 154, 154 'and 155, 155' of the side walls 152 and 153.
- said projecting part of a package 135 ′ can equally be located on one side or the other of the package with respect to the projecting part of the previous package 135 or 170.
- the weight of the upper packaging is taken up by the T-shaped side faces, and guarantees good resistance to vertical compression of the stacked packaging as well as protection of the yoghurt pots.
- FIG. 7 shows another embodiment of the blank 201 according to the invention which has the particular feature of allowing the stacking of three layers of containers.
- the blank 201 therefore has, for example, a bar of T 213, 214, for the flaps 203 and 205, of height corresponding to that of two layers of containers, the preceding modes showing bars of height corresponding to a single layer.
- the rest of the blank 201 is also identical to the blank described with reference to FIG. 1.
- FIGS. 8 and 9 show a device 301 for packaging packs 302 of yogurt pots comprising a magazine 303 for supplying blanks or blanks 304, known in itself.
- a gripping device 305 by suction or vacuum is provided for unstacking the cutouts which are then pushed one by one, flat, again here in a manner known per se, by means 306 on a table 307 to the station 308 where the blank is placed below, at a distance from a horizontal parallelepiped mandrel 309.
- An adhesive injector 310 is provided for gluing the top 311 of an end flap (see FIG. 10), during the operation of bringing to station 308.
- top 312 of a secondary flap will for example be glued later.
- the intermediate structure suitable for receiving the packaging is then produced at station 308 in the following manner.
- the T-shaped flaps are folded down (shown in dashed lines in FIG. 11) by means 313, such as push cylinders against the lateral faces 314 of the mandrel 309, the latter having lower edges 315 suitable for precisely coinciding with the first fold lines separating the central flap from the T-shaped flaps
- the device 301 furthermore comprises a chain with reciprocating motion in noria 319 provided with a succession of shoe trees 320 regularly spaced apart and for example constituted by four parallel pins 321 of height equal to that of the leg of the T-shaped flaps, arranged at the four corners of a parallelepiped of dimension slightly smaller than the dimensions of the belt 322 formed by the folding of the flaps.
- the device comprises pushing means, horizontally, of the intermediate structure thus formed on a vertical lateral side 323 of the chain.
- the belt 322 therefore fits into the shoe trees arranged horizontally.
- Pre-folding means towards the outside of the main flaps to open the intermediate structure and pre-folding of the projecting parts are provided at station 326, for example by spacer cylinder.
- Automatic means 327 for introducing the packs of pots are provided for filling in the lower part of the intermediate structure, then in the upper part at the next station.
- the device 301 further comprises means 328, adapted to fold the upper flaps over the covers of the upper ply, then the protruding parts one against the other of the packages after filling, and a glue injector for gluing said projecting parts.
- the packages 331 are then brought into position to be taken up manually or mechanically, for example by the arm of a robot 332, to directly constitute the pallet 333.
- FIGS. 13 to 16 show other embodiments of blanks according to the invention having a flat cover, devoid of any projection other than that obtained by the detachment of the precut part, once the latter has been raised to allow the gripping the packaging.
- FIGS. 13, 14, 15 and 16 respectively show cardboard blanks 401, 402, 403 and 404 comprising in an identical manner a series of five flaps as described above, namely three substantially rectangular flaps 405, 406 and 407, and two flaps 408 and 409 T-shaped, the flaps being connected to each other by first fold lines 410 parallel to each other.
- the two T-shaped flaps of the blank 401 of FIG. 13 each include a main flap, 411 and 412, provided with a rectangular main part 413 of length equal to that of the upper bar of the T to which they are attached by fold lines 414 perpendicular to the first fold lines, and of width equal to half the width of the central flap 406.
- the flaps 411 and 412 also each have a secondary flap 415 attached to the side of the Main flap concerned opposite the fold line
- the flap 412 further comprises two external ears 416 on either side of the secondary flap 415, constituted by two end extensions adapted to cooperate with the other flap 413, with which they are for example secured by bonding.
- the handle 419 is for example constituted by a central orifice 420, for example oval, crossed right through in the transverse direction by a tongue
- Figure 15 shows a variant of the embodiment of Figure 14, a single main flap
- This main flap is provided with an end tab attached to the edge opposite to that of the fold line.
- FIG. 16 shows another variant of blank 404 comprising two main flaps 425 of width greater than half of the central rectangular flap 406, which allows overlap of the two flaps when folded over each other.
- a handle device 426 is also provided, for example, constituted by two oval orifices respectively made on the two flaps, which makes it possible to release a longitudinal central gripping strip, fold lines 427 substantially forming a triangle the apex of which is located at level of the oval holes and the base of which is formed by the fold lines 414 also being advantageously provided.
- FIG. 17 shows a blank 428 of corrugated sheet comprising here again a series of five flaps 429, 430, 431, 432 and 433 connected to each other by first fold lines 434 parallel to each other.
- the five flaps consist of three substantially rectangular flaps 429, 431 and 433, including two end flaps 429 and 433 of symmetrical shape with respect to a straight line 435 (in dashed line in FIG. 17) of symmetry of the blank and parallel to the first fold lines 434, and a central flap 432.
- the substantially rectangular flaps are here again separated in pairs by two identical flaps 430 and 432 in the shape of a T comprising a central leg and an upper bar extending over a dimension corresponding to the length of a sheet of container, the height excluding all of T corresponding to the height of a whole number of containers.
- the flaps 430 and 432 are devoid of any flap, or each comprise a rectangular flap 436 (a dashed line in the figure) of length equal to that of the bar of the T and of reduced width, for example equal to the quarter of the width of the structure, as shown in Figure 18.
- a handle 437 for example formed by a strip of reinforced paper glued to the bars of T straddling the packaging, is planned.
- FIGS. 19 to 21 other embodiments of a blank and of a packaging according to the invention are shown.
- FIG. 19 shows a blank 439 comprising a series of three flaps, namely a rectangular central flap 440 and two identical side flaps 441 and 442 in the shape of a T, the ends of the legs 445 of which are respectively connected to said central flap by first lines of parallel folding 443, symmetrical with respect to a central straight line 444 of the central flap.
- Each leg 445 is connected by second fold lines perpendicular to the first fold lines to two substantially rectangular lateral flaps 446, of width corresponding to that of the wings 447 of the bars of T, situated on either side of said leg so that the whole of the blank 439 is substantially inscribed in a rectangle.
- These lateral flaps have d ⁇ B protruding parts 448 like the end flaps of the blanks described above.
- the blank 439 comprises, at the end edges of the T-shaped shutter bars, rectangular flaps 450, capable of at least partially covering the lids of the containers of the upper ply and / or / on either side of the central flap 440, rectangular secondary flaps 451 (in thin lines in the figure) of width equal to that of the branches 447 of T and connected said central flap by second fold lines perpendicular to the first lines.
- FIGS. 20 and 21 show a blank 452 and the package 453 obtained with such a blank, according to another embodiment of the same type as that shown with reference to FIG. 19, comprising a rectangular central flap 454 and two lateral flaps in form of T 455 and 456, provided with flaps 457 and 458 of the type described above.
