Throughout the description, the terms used and, mainly "height". "low", "lower" and "superior" are understood for a set of packaging and of jars of yogurt normally placed on a surface horizontal, with the bottoms of the yogurt jars facing down.

Figures 1 and 2 represent a set 1, which It comprises a group of four jars of yogurt or compote 2 and a 3 type liner packing lining the jars 2. For greater clarity, jars 2 are represented in mixed strokes, and two of these jars have not been fully represented in the Figure 1.

Jars of yogurt 2 are identical and comprise, respectively, a truncated conical body 4 converging towards the bottom 5 from jar 2.

Each jar 2 is finished, at the level of its tip 7, by a flange 8 covered, generally, by a closing opercle. The four jars 2 are regrouped in two rows of two jars, arranged one in front of the other, namely one front row 10 and a back row 11.

The packaging 3 comprises an anterior wall 13 (a the left of figures 1 and 2), a rear wall 14, a upper wall 15 and a lower wall 16.

The anterior wall 13 extends in front of the previous row 10, about a height and width that are, respectively, slightly greater than the height and width from the group of jars 2.

The upper wall 15 extends from the edge upper 17 of the anterior wall 13 to the upper edge 18 of the back wall 14, passing over all the jars of yogurt 2.

The bottom wall 16 extends from the edge lower 19 of the anterior wall 13 to the lower edge 20 of the back wall 14.

The anterior walls 13 and posterior 14 are They extend downward with slight convergence with each other.

The rear wall 14 has a height h clearly less than the height H of the previous wall 13.

The lower edge 20 of the rear wall 14 it is located, therefore, at a level clearly higher than that of the lower edge 19 of the anterior wall 13.

The bottom wall 16 comprises, from the edge bottom 19 of the anterior wall 13, a horizontal part 22 located on the bottom 5 of the jars 2 of the previous row 10, a then a part 23, which is inclined upwards and towards behind the packaging 3 and joining the bottom edge 20 of the wall back 14.

The inclined part 23 comprises two openings identical rear 24 with contours 25 with a general shape elliptical Each opening 24 receives the frustoconical body 4 of a jar 2 of the back row 11. The shape of the contours 25 is adapted so that they fit around the bodies 4 corresponding, retaining them by blocking.

The inclined part 23 also includes two identical anterior openings 26 with contours 27 with a shape general of ellipse arc. Each opening 26 receives a part rear 28 of the truncated conical body 4 of a jar 2 of the row previous 10.

The shape of these contours 27 is adapted to that these fit around the corresponding bodies 4, retaining them by blocking.

The inclined part 23 of the bottom wall 16 it also includes anterior rectangular folds 30 and posterior 31, respectively associated with a previous opening 26 or later 24. Each fold 30 extends substantially, from vertical way, from a region of a contour 27, slightly hooked back. Each fold 31 also extends substantially vertically from a region of a contour 25 slightly off the front.

The two folds 30 extend, respectively, along the body 4 of a jar 2 of row 10 leaning on this body 4.

The two folds 31 extend, respectively, along the body 4 of a jar 2 of row 11 taking support on this body 4.

The horizontal part 22 of the bottom wall 16, comprises, at the level of each fund 5 of the jars 2 of row 10, a previous extension 32 in disk segment, and a posterior extension 33 substantially trapezoidal, in order to increase the contact surface between part 22 with bottom 5 of jars 2 of the previous row 10.

The anterior wall 13 comprises, for each jar 2 of row 10, a reception opening 34 of a previous region from bottom 5 of jar 2. This opening 34 is bordered by two triangular tabs 35 for bottom retention 5 correspondent.

The anterior wall 13 also includes for each jar 2 of row 10, a substantially horizontal opening 36 of receiving and retaining the flange 8 of jar 2 correspondent.

The rear wall 14 comprises, so analogous, two noticeably horizontal reception openings 37 and of retention of the flanges 8 of the jars 2 of the back row eleven.

The upper wall 15 finally comprises rectangular extensions anterior 39 and posterior 40 to the height of openings 36 and 37, to receive the regions of the Flanges 8 received in openings 36 and 37.

Two arc recesses have been made circle 41 on the sides of the upper wall 15.

Figure 3 illustrates a cardboard plate elongated 50 or pattern, which allows to manufacture the packaging 3 by creased. In this figure, the fold lines have been represented in dashed lines and strong cut lines.

This plate 50 comprises, successively, articulated with each other, six substantially rectangular panels 51 up to 56.

Panel 52 corresponds to the anterior wall 13, panel 53 corresponds to the horizontal part 22 of the wall bottom 16, panel 54 corresponds to the inclined part 23 of the bottom wall 16, and panel 55 corresponds to the back wall 14.

The length of panel 52 (corresponding to height H ) is greater than the length of panel 55 (corresponding to height h ).

Panel 56, of small length, is a fold to glue panel 51, which is meant to be practically covered by the latter, forming the upper wall 15.

The two rectilinear grooves 57 are formed in panel 52, in the vicinity and parallel to a line of discontinuous and transverse fold 58, which joins panels 51 and 52

Each slot 57 is terminated in curved limbs that join with the fold line 58. A cavity noticeably rectangular 59 is practiced on the edge the central part of each slot 57, on the side of a dashed fold line and transverse 60 linking panels 52 and 53.

Each slot 57 is intended to delimit in the moment of folding of pattern 50, on the one hand an extension 39 of the upper wall 15 and, on the other hand, with the cavity 59 corresponding, the corresponding opening 36 of the wall previous 13.

Panel 52 has two grooves 61 in arc of circle, formed in the vicinity of the fold line 60 and that They join with it. Each slot 61 is extended, in its part central, through a groove 62 parallel to the longitudinal axis of the pattern 50. Two oblique grooves 63 extend on either side of each slot 62 towards each end of the corresponding slot 61.

After folding pattern 50, each slot 61 is intended to delimit an anterior extension 32 of the wall bottom 16, the corresponding opening 34 in the anterior wall 13 and, with the corresponding grooves 62 and 63, the tabs corresponding retention triangles 35 of the anterior wall 13.

Two pairs of oblong cavities have been practiced 64 on panel 54 in the vicinity of a fold line discontinuous and transverse 65, which joins panel 53 with panel 54

The cavities 64 of the same pair are joined, on the one hand, each other by a rectilinear groove 66 transverse to the longitudinal axis of the plate 50, and are prolonged, on the other part, respectively by a longitudinal groove 67 in relation to to the axis of the plate 50. For each pair of cavities 64, these cavities 64 and slots 66 and 67 delimit a rectangular spoiler 68, joined by a fold line 69 with the rest of panel 54 and a trapezoidal spoiler 70 attached to panel 53.

For each pair of cavities 64, the cavities 64 are intended to delimit an anterior opening 26 of the wall bottom 16 of packaging 3 formed. The ailerons 68 and 70 corresponding are intended to form, respectively, the corresponding fold 30 of the bottom wall 16 and the extension corresponding rear 33 of part 22 of wall 16.

Panel 54 also presents two cavities. 72, whose outline corresponds mainly to an ellipse. Every cavity 72 is extended by two parallel rectilinear grooves 73 to the longitudinal axis of the plate 50. These grooves 73 delimit, in part, two rectangular ailerons 74 joined, respectively, by  a fold line 75 with panel 54. Each spoiler 74 is extends, in part, into the corresponding cavity 72.

The cavities 72 are intended to form the rear openings 24 of the bottom wall 16, and the ailerons 74 they are intended to form the corresponding folds 31.

The shapes of the cavities 72 and, likewise, of the cavities 64, they are adapted, on the one hand, to the inclination that panel 54 will take to form part 23 of the wall 16 and, on the other hand, in the form of jars 2.

Two rectilinear grooves 76 are formed in the panel 55 in the proximity and parallel to a fold line discontinuous and transversal 77 that joins panels 55 and 56. These Slots 75 are finished in curved limbs that join with the fold line 76.

Two cavities 78 in circle arc are formed, respectively, on one side of panel 51 and are intended to form the recesses 41 of the upper wall 15 of the packing 3.

To form the packaging 3 of Figure 1, it is cover the jars 2 with the iron 50, then stick the panel 51 on panel 56. The union of these two panels 51 and 56 you can also ensure in any other way known.

The packaging 3 formed in this way ensures a satisfactory retention of jars 2, mainly thanks to the conjugate forms of the bodies 4 of the jars 2 and of the contours 25 and 27 of openings 24 and 26, thanks to the folds 30 and 31, thanks to the horizontal part 22 of the lower wall 16 and a  its extensions 32 and 33, thanks to openings 36 and 37 of the anterior and posterior walls 13 and 14 and thanks to the upper wall fifteen.

It should be noted that the bottom wall 16 cooperates with jars 2 of back row 11 at a level higher than the one in which cooperates with jars 2 of the previous row 10.

The recesses 41 facilitate the clamping of the 3. According to variants not shown, they may be replaced by other equivalent means such as holes

The anterior face 13 extends over the entire height and width of groups of jars 2 and therefore presents a maximum area available to support information.

In this case, the asymmetric shape of the profile of the packing 3, with the rear wall 14 of small height and the presence of the inclined part 23 of the lower wall 16, allows limit the total surface of the plate 50 used.

Thus, at anterior wall dimensions 13 same, the surface of the plate 50 used is clearly smaller than that of an iron intended to form a packaging of symmetrical section, which completely covers the group of jars of yogurt.

According to variants, not shown, the height of the rear wall 14 can be very small and even void.

The invention can obviously be applied to conditioning of any type of objects, in particular of containers Obviously, the invention allows conditioning groups of variable numbers of objects, for example that understand 2x3 or 2x4 objects.
