Description

The invention relates to the field of packaging packs comprising several layers of pots grouped next to each other, thanks to a cardboard packaging of tubular envelope type matching the layers of pots, made by volume and closure on it even a flat cardboard blank.

More specifically, the subject of the invention is a cardboard blank, flat, intended for the formation of a packaging of a pack including at least two layers of pots each comprising four pots two by two side by side and facing each other. opposite, positively spaced and wedged on their side walls in the vicinity of their top walls, a method of making such a pack, and finally a package of such a pack.

A pot, such as that of the pack considered, comprises a bottom wall, a side wall closed on itself, and a top closure. In a simple embodiment, the pot is in the form of a truncated cone and has a transverse flange towards its upper opening, the top closure being a flat seal secured to and on the collar. In other embodiments, the generatrix of the sidewall is a line other than a straight line, having a more or less complex shape, and the guide curve may be other than a circle, for example a curvilinear square with rounded corners . Such a pot can stand upright by resting on its bottom wall forming a seat. In other embodiments, the side wall is rounded to join the bottom wall.

In one embodiment, such a pot can be made of thermoformed plastic material and it has a certain holding allowing it to be self-supporting, but the pot can be made of other materials and by other methods.

Such a pot is typically intended to contain a homogeneous content or not, having a more or less fluid overall state, which does not exclude the presence of more or less solid pieces. Such content is for example a dairy product or a dessert, this list is not limiting.

In one embodiment, the pot is intended to receive a dose of such a content for individual and unitary use, for example of the order of a hundred grams and, in this case, it can have a height of the order a few centimeters and register laterally in a cylinder whose diameter is also of the order of a few centimeters. In other embodiments, the pot for a minidose is smaller or, on the contrary, for a larger dose, is larger. The pot can also be a bottle, intended for a larger dose.

In a possible elementary embodiment, the pack comprises for example a lower layer of four pots, two by two side by side and facing each other, in a square, and an upper layer of four pots arranged on the lower layer of the same. way. In other embodiments, the pack includes more than two layers of stacked pots. In other embodiments, a layer comprises more than four pots, in particular arranged in three - or more - longitudinal rectangles and two transverse rows.

In known manner, particularly from the document EP 0461947 a cardboard packaging, in the form of a tubular envelope, for a pack of pots comprising a single layer of four pots, is made from a cardboard blank, flat, of rectangular general shape, bounded by two free edges in the longitudinal direction and two free edges in the transverse direction.

• disposés les uns à la suite des autres le long de la direction longitudinale, un premier panneau de dessus, un premier panneau latéral, un premier panneau de liaison, un panneau de base, un second panneau de liaison, un second panneau latéral, un second panneau de dessus, le premier panneau de dessus et le second panneau de dessus étant agencés de sorte à être aptes et destinés à être disposés de façon coplanaire et solidarisés l'un à l'autre pour la fermeture sur lui-même du flan mis en volume, la formation d'une paroi de dessus de l'emballage, et la mise en forme de l'emballage et du pack,
• des lignes rainées de direction transversale, aptes et destinées au pliage des panneaux, à la mise en volume du flan et à la mise en forme de l'emballage, dont deux lignes rainées de base, entre le panneau de base et les deux panneaux de liaison, et deux lignes rainées intermédiaires, entre les deux panneaux de liaison et les deux panneaux latéraux,
• des lignes découpées,
• une partie de réception, pleine, s'étendant de façon substantielle sur le panneau de base, apte et destinée à la réception des pots par leurs parois de dessous.

Such a blank includes:

• arranged one after the other along the longitudinal direction, a first top panel, a first side panel, a first connecting panel, a base panel, a second connecting panel, a second side panel, a second panel, top panel, the first top panel and the second top panel being arranged so as to be suitable and intended to be arranged coplanar and secured to one another for the closure on itself of the blank set volume, forming a top wall of the package, and shaping the package and pack,
• grooves of transverse direction, suitable and intended for folding the panels, the volume of the blank and the shaping of the package, including two basic groove lines, between the base panel and the two panels of connection, and two intermediate slotted lines, between the two connecting panels and the two side panels,
• cut lines,
• a receiving portion, solid, extending substantially on the base panel, adapted and intended for receiving the pots by their bottom walls.

In order that, in the pack produced, the pots can not, or can only slightly, move unintentionally or shock each other, it is expected that the cardboard blank also includes a portion of spacing / wedging , fit and intended, once the packaging and the shaped pack, spacing and wedging pots of wedging relative to each other in the vicinity of their bottom walls.

In the embodiment described in the document EP 0461947 , this spacer / wedge portion comes from the base panel, with slotted and cut lines. It is intended to be put in volume relative to the receiving part. Thus, stop edges are formed on the side walls of the pots, in the vicinity of their bottom walls. More specifically, the spacer / wedging portion comprises a lower holding system, consisting of four opposite tabs, adapted to be superimposed and glued to ensure a spacing of the vertical blanks of the shim volume.

With such an arrangement, the implementation of the wedge requires going through a first stage of setting volume of the hold, and a second step of bonding the holding tabs two by two. In addition, the wedge must be formatted prior to the arrangement of the pots on the base panel and the setting volume of the blank. As a result, the volume of the complexed flan is increased because it requires a large number of intermediate steps.

Starting from the realization of flat cardboard blank, known for the indicated destination, which makes it possible to form a final packaging of a pack, of tubular envelope type, the pack including at least one layer of pots comprising at least four pots of wedging two by two side by side and vis-à-vis, positively spaced and wedged on their side walls in the vicinity of their top walls, the blank comprising two top panels, two side panels, a base panel, a means of solidarity for the closing on itself of the blank set volume; cut lines, and slotted lines, and notched lines, suitable and intended for folding the panels, the setting volume of the blank and the shaping of the package and the pack; a spacing / wedging portion of the positively spaced and wedged clamping pots, from a top panel with cut-out lines, which can be volume-adjusted relative to the top panel, so as to form wedges for the pots of wedge, thus positively spaced and wedged on their side walls in the vicinity of their top walls, the problem underlying the invention is to provide a spacer / wedging portion that requires neither an external pre-folding machine, nor a formatting prior to positioning of the pots. This problem is posed in combination with that part of spacing / wedging whose realization involves a saving of cardboard.

Hereinafter a detailed discussion of several embodiments of the invention with examples and reference to the drawings.

A cardboard blank 1, flat, is intended for the formation of a package 5 of a pack 2, the pack 2 also comprising pots 3, at least four pots called "clamping pots 3a".

The packaging 5 is of tubular casing type and is made by placing in volume and closing on itself the blank 1, so as to marry the pots 3 of the pack 2 which are thus kept together.

By "tubular casing" it should be understood that the package 5, having generally six faces and forming a generally parallelepipedal shape, comprises at least four adjacent faces closed on themselves and for example two faces facing each other. open screws in the examples of the figures.

The term "pack" should be understood to mean a batch consisting of several pots 3 presented grouped in layers - with superposition in case of plurality of layers - in longitudinal rows and in transverse rows, in a package, such as in the a tubular tubular envelope, so as to form a unitary unit, intended to be stored, handled, moved, offered for sale and sold as such.

The pots 3 included in the pack 2 comprise at least the four clamping pots 3a. The qualification of "pot of calibration 3a" aims to distinguish such a pot of a possible other pot of the pack 2, namely a pot of lower layer 3b. In the description, the expression "pot positively spaced and wedged 3a" applies to a shim pot 3a, once it is actually positively spaced and wedged, compared to the other shims 3a, while the expression "pot calibration 3a" applies to such a pot 3a which is not yet positively spaced and wedged.

The description with reference to Figures 1 to 4 relates to the particular embodiment of a pack 2 of pots 3, having two layers, including a lower layer 4a of four pots 3 called, by ellipse, lower pots 3b, and an upper layer 4b of four jars 3a superimposed on the lower layer 4a, the pots of each layer being two by two side by side and vis-a-vis, arranged in a square and positively spaced. This particular case is aimed at an elementary blank 1, an elementary packaging 5 and such an elementary pack 2.

However, more generally, the invention also relates to any blank 1, any packaging 5 and any pack 2, made from, or comprising, or derived from such an elementary blank 1, such an elementary packaging 5 and a such elementary pack 2, or including its spacing / setting means. Such embodiments are illustrated in a nonlimiting manner by the figure 5 , showing that a pack 2 may comprise a single layer of pots or pots other than the lower four 3b and the four pots 3a calibration. In all the possible embodiments within the scope of the invention, the pack 2 includes the four clamping pots 3a of the upper pot layer which are positively spaced and wedged, according to the invention.

By "carton" is meant a layered material, such as that commonly used or adapted to a blank having the indicated destination. Such a cardboard must be neither too rigid nor too flexible. It must be able to be folded at the place of slotted lines provided for this purpose.

By "pot" 3, it is necessary to understand a container as described in the introductory part and whose characteristics do not need to be described again here, being reminded that such a pot 3, which has a certain held allowing it to be self-supporting, comprises a bottom wall 6c, a side wall closed on itself 6a, to form a pot body, with an opening opposite to the bottom, and a top closure 7. The pots 3 are individualized. In the context of the invention, the pots 3 of a given pack 2 are for example similar, especially identical, and they are filled with a certain content, identical or not for the different pots 3, and closed. The pots 3 have for example globally a spherical shape, with an opening narrower than the body of the pot.

By "flat" in the expression "flat blank", it should be understood that the blank 1 is deployed, so as to be at least substantially in one and the same plane P. Unless otherwise expressed the term "Blank" 1, without further clarification, should be understood as targeting blank 1 flat, as opposed to volume blank 1 which then forms packaging 5.

We now refer to Figures 1 to 4 concerning the case of a basic pack 2 having two layers of pots, including a lower layer 4a of four lower pots 3b, two by two side by side and facing each other, arranged in a square, and an upper layer 4b of four clamping pots 3a, two by two side by side and vis-à-vis, arranged in a square, which in the pack 2 are, in fact, positively spaced and wedged.

We can define, relative to the blank 1 in the plane P, a longitudinal axis, or longitudinal direction, A and a transverse axis, or transverse direction, B, perpendicular to each other, and a C axis perpendicular or substantially perpendicular to the plane P , subsequently defining the axis of the package C, or the direction of the package.

The blank 1 comprises, for example, arranged one after the other in the direction of the longitudinal axis A, extending transversely, a spacing / wedging portion 15, a first top panel 10a, a first side panel. 11a, a base panel 12, a second side panel 11b and a second top panel 10b. The first top panel 10a, the first side panel 11a, the base panel 12, the second side panel 11b and the second top panel 10b are more generally referred to as "tubular blank panels", and together form the body 1 has blank 1.

The body 1a of the blank 1 is for example limited by two edges 8 in the direction of the longitudinal axis A and two edges 9 in the direction of the transverse axis B. In the embodiment shown, the body 1a of the blank is generally rectangular in shape. The two edges 8 delimit the two edges of the two open faces of the package 5.

By "panel" is meant a flat piece in the form of a layer, made of cardboard in this case, delimited by a border comprising slotted lines and / or cut lines.

The blank 1 may also include a means 14 for securing the two top panels 10a, 10b to each other for closing on itself the blank 1 placed in volume with the formation of a top wall 10c. For example, the second top panel 10b is wide (in the direction of the longitudinal axis A) and is intended to form the entire surface of the top panel 10c, whereas the first top panel 10a is narrow (according to the direction of the longitudinal axis A), as a flap, and provided for example with a bonding glue 14, adapted to come on the back of the first top panel 10a. Such an embodiment is not exclusive of others, for example by a means of securing by cooperation of tabs and notches.

A top panel is generically designated 10 and, similarly, a side panel 11.

The body 1a of the blank 1 also comprises cut lines and grooved and notched lines. These lines are suitable and intended for the relative folding of the panels 10, 10a, 10b, 11, 11a, 11b and 12, the setting volume of the blank 1 and the shaping of the package 5 and the pack 3 The slotted and slotted lines actually include slotted sections interspersed with cut-out sections. More precisely, these lines may be of the "5/5" type, that is to say that the slotted and cut sections have a length of five millimeters.

The blank 1 comprises for example two base lines 17 between the base panel 12 and the two side panels 11, 11 a, 11 b, two top lines 18 between the two side panels 11, 11 a, 11 b, and the two top panels 10, 10a, 10b and three cutout portions 19 between the spacing / wedging portion 15 and the first top panel 10a. The baselines 17 and the top lines 18 are for example slotted and slotted lines.

The blank 1 is such that the two side panels 11a and 11b have for example the same size and the second top panel 10b and the base panel 12 have the same size.

By "size" can for example include longitudinal dimensions, transverse dimensions, a perimeter or a panel area.

The blank 1 comprises, in the plane P, a longitudinal median axis, oriented in the longitudinal direction A, a transverse central axis oriented in the transverse direction B, with an intersection X. The blank 1 also comprises a normal axis C, perpendicular or substantially perpendicular to the plane P. This axis C is still called the axis of the package 5. The blank 1 may be symmetrical or substantially symmetrical with respect to the longitudinal central axis A. It is symmetrical or substantially symmetrical with respect to the axis transverse median B, excluding the top panels 10a and 10b and the spacing / wedging portion 15. As for the intersection X, it is located substantially in the center of the base panel 12.

The pot spacing portion 15 (sometimes referred to as "spacing / wedging portion 15" by ellipse) includes a central portion 15a extending in the longitudinal direction between ends. longitudinally opposite and in the transverse direction, so as to be substantially narrower in the longitudinal direction than in the transverse direction. The central portion 15a is framed by four fins 15b, of generally rectangular shape. The four vanes 15b are disposed symmetrically on both sides of the longitudinal ends of the central portion 15a, so that the spacing / wedging portion 15 is generally H-shaped with a central bar oriented in the transverse direction.

The three cutting portions 19 are adapted and intended to separate the spacing / wedging portion 15 of the body 1a of the blank 1 during its setting volume relative to the first top panel 10a. The three cutting portions 19 are for example notched lines. The cutting portions 19 are designed to be broken in a controlled manner by application of a predefined force, in particular in the longitudinal direction. When the spacing / wedging portion 15 of the blank is disposed vertically of a space between two rows of pots, the spacer / wedge portion 15 of the blank can thus be detached from the blank by applying a force according to the invention. packing direction vertically of said space between two rows of pots which causes a shaping of the spacing / wedging portion 15 and thus a force in the longitudinal direction applied to the cutting portion 19, as described more before hereinafter.

For this purpose, the cutting portions 19 may comprise notched portions and slotted portions of various shapes. In this example, the notched and grooved portions are diagonal, that is to say inclined, with respect to the direction of the longitudinal axis A, so as to promote the cutting of the cardboard fibers and ensure relatively easy detachment . The spacing / wedging portion 15 also comprises four curved alignment lines 24, curves, between the fins 15b and the central portion 15a.

The cutting portions 19 are for example located on the edge of the fins 15b adjacent to the first top panel 10a, and on the edge of the central portion 15a framed by said fins 15b in the transverse direction. The offset of the cutting portions 19 located on the edge of the fins 15b with the cutting portion or portions 19 located on the edge of the central portion 15a avoids a bend of the spacing / wedging portion 15 when from handling the blank 1 to flat.

The curved shape of the grooved wedging lines 24 of the spacing / wedging portion 15 also makes it possible to match the shape of the pots when the spacing / wedging portion 15 is set in volume as will now be described.

Specifically, when the spacer / wedge portion 15 is volume-adjusted relative to the first top panel 10a, the central portion 15a then forms the bottom of the spacer / wedge portion 15 and ensures the spacing of the spacers. wedging 3a, and the fins 15b form wedging walls 16 for the clamping pots 3a, adapted to wedge on their side walls 6a, in the vicinity of their top walls 6b.

The curvature of the slotted timing lines 24 makes it possible to follow the shape of the pots when the wedging walls 16 are in contact with the clamping pots 3a. This also prevents the inclination of the bottom 23 to ensure the proper maintenance and spacing of the clamping pots 3a. In cross-section, and when it is in volume, the spacing / wedging portion 15 thus has a generally U-shaped, the fins being perpendicular to the central portion 15a.

The blank 1 may further comprise four openings 20, arranged along the top lines 18 grooved and notched, two by two vis-à-vis, generally shaped for example crescent, and whose convex part is turned towards the base panel 12. These openings 20 form receiving portions 21, adapted and intended to cooperate with the side wall 6a of a clamping pot 3a, in the vicinity of their top walls 6b.

More specifically, the concave portion 22b of the aperture 20 is adjacent to or in contact with the top closure 7 of the clamping pots 3a, while the convex portion 22a of the aperture is adjacent to or in contact with the side wall 6a of the calibration pots 3a.

When the blank 1 is set in volume, the clamping pots 3a are wedged between on the one hand the wedging walls 16, and on the other hand the receiving portions 21.

The blank 1 may also comprise a lower setting system 13 of the lower pots 3b. Such a locking system may for example comprise tabs arranged on the base panel, or foldable tabs present on the sides of the base panel and acting as gussets.

By way of example, purely non-limiting, the total longitudinal dimension of the blank 1 may be approximately equal to 54 centimeters (cm) and the respective longitudinal dimensions of the spacing / wedging portion 15, of the first base panel 10a, the first side panel 11a, the base panel 12, the second side panel 11b and the second top panel 10b can be respectively between 4 and 5cm, 2 and 3cm, 12 and 13cm, 11 and 12cm, 12 and 13cm and 10cm. and 11 cm.

The transverse dimension of the base panel 12 may be between 12 and 13 cm, this dimension being substantially close to the largest transverse dimension of the other tubular blank panels.

Finally, the central portion 15a may have dimensions of between 0.5 and 1 cm.

The blank 1 and the spacing / wedging part 15 described can be adapted and adapted in particular according to the shape of the pots 3 or the number of pots 3, as described below.

We now refer to the figure 5 which represents a blank 1 specially adapted and intended for a pack 2 having a single layer of four pots 3, namely four clamping pots 3a.

The four clamping pots 3a of the single layer of pots are received by the base panel 12 and are spaced and wedged on their side walls 6a in the vicinity of their top walls 6b, with the spacer / wedging means according to those previously described with reference to Figures 1 to 4 .

In relation to the achievement of Figures 1 to 4 , in the illustrated nonlimiting embodiment figure 5 , it is not expected that the blank 1 comprises perforations cut to receive the top walls of the four pots 3a because in this configuration, the clamping pots 3a are retained at their bottom wall 6c by the wedging system lower 13.

On the other hand, the longitudinal dimension of the side panels 11, 11a, 11b between the base line 17 and the top line 18 is reduced, as well as the degree of curvature of the longitudinal wall at the side panels 11, 11a, 11b. Because of this lower degree of curvature, the transverse dimension of the top panels 10, 10a, 10b is also reduced.

We now refer to the figure 6 which represents a blank 1 which is specially adapted and intended for a pack having two layers of eight superimposed pots, the eight pots of the upper layer being pitch pots.

What has been described above with reference to the realization of Figures 1 to 4 relative to the existence of two layers of superimposed pots can be transposed to the realization of the figure 6 relative to the existence of these two layers.

Moreover, in relation to the achievement of Figures 1 to 4 , the blank 1 of the figure 6 is such that, in the transverse direction, it comprises, towards one of its longitudinal edges, an extension of the top panels 10, 10a, 10b, the side panels 11, 11a, 11b, of the base panel 13 and of the spacer / wedging part 15.

The extension may be provided towards one or towards the other or towards the two longitudinal edges 8.

Such extension of the base panel 12, whose dimension in the direction of the transverse axis B is adapted to use, is for example intended for the reception of at least four additional pots 3c, arranged side by side and screw -a-vis. Thus, the pots 3 of the lower and upper layers are respectively arranged in four longitudinal rows and two transverse rows. The invention also relates to the case where a greater number of longitudinal rows is provided.

On the other hand, the spacing / wedging portion 15, elongated transversely, comprises a number of fins 15b associated with the number of clamping pots 3a. Thus, in this particular embodiment, the spacing / wedging portion 15 comprises eight fins, arranged two by two symmetrically with respect to the central portion 15a, so that each wedging wall 16 is facing a side wall 6a of a shimming pot 3a when setting the volume of the spacer / wedging portion 15.

Finally, the number of openings is increased in the same way in proportion to the number of setting pots, so that when the blank 1 is shaped, the top closures 7 of the pots 3a are in contact with the portion concave 22b of the openings 20.

The invention also relates to a method for producing packaging 5 and pack 2, described more particularly with reference to the production of Figures 2 to 4 .

For this process, there is available a cardboard blank, flat, 1, four jars 3a and four lower jars 3b intended to be part of the pack 3.

Then, the four lower pots 3b are placed in a lower layer of pots 4a on the base panel 12, the blank 1 then being arranged horizontally horizontally, so that the lower pots are, for example, arranged side by side and side by side. vis-à-vis, square.

Then, the four shimming pots 3a are placed on the lower pots 3b, the bottom walls of the shimming pots being for example in abutment against the top closures 7 of the lower pots 3b, so that the shimming pots 3a are two to two side by side and vis-à-vis, square. There is then at least one wedging spacing between the clamping pots 3a. The staggering spacing extends for example at least in the transverse direction and is adapted to accommodate the shaped spacing / wedging portion 15 as will now be described.

Then, without changing the positioning of the pots, volume 1 is made around the jars 3 of the pack 2, by folding the side panels 11, 11a, 11b around the two base lines 17, and the first top panel 10a around a first adjacent top line 18.

The central portion 15a of the spacing / wedging portion 15 is then arranged vertically, in the packaging direction, of said wedge spacing between two rows of adjacent clamping pots 3a.

Then, pressure is exerted on the central portion 15a of the spacing / wedging portion 15, in particular in the packaging direction, so as to move the central portion 15a relative to the first top panel 10a, and bring it closer. relative to the base panel 12, between two rows of longitudinally adjacent wedging pots 3a, until the spacing / wedging portion 15 is separated from the first top panel 10a at the three cutout portions 19. By exerting the pressure, the fins 15b are bent at the four grooved skewing lines 24. Then, it ceases to exert the pressure when the wedging walls 16 of the vanes 15b are in direct contact with the transverse walls 6a of the clamping pots 3a.

Then, the second top panel 10b is folded around the second grooved and notched top line 18, and is arranged coplanar, for example on top of one another, and the two are secured to each other. two top panels 10a and 10b, so as to close on itself the blank placed in volume, to form the top wall 10c, by implementing the securing means 14, and to shape the package 5.

In this step, the top closures 7 of each clamping pot 3a are cooperated with the receiving portions 21 provided on the side panels 11, 11a, 11b.

It is possible to have a suitable blank 1 for a pack 2 of a single layer of pots or a blank 1 suitable for several layers of pots may be available. It is also possible to have a blank 1 suitable for receiving four setting pots 3a, or a suitable blank 1 for a layer (s) comprising additional pots, for example eight pots. Depending on the case, and with the implementation of the blank 1 adapted, or we have the four jars 3a in a single layer of pots, or we have first the lower layer of pots, then the layer of jars higher.

A package 5 is especially illustrated figure 4 in the case of the realization of Figures 1 to 4 .

The pack 5 shaped, the base panel 12 is disposed in the plane P. The bottom 23 formed by the transverse central portion 15b and the top panel 10c are parallel to the base panel 12, spaced along the C. The two side panels 11, 11a, 11b extend perpendicularly or substantially perpendicularly to the plane of the base panel 12, to the top wall 10c, disposed above and in line with the panel. base 12.

In the shaped package, the spacer / wedge portion 15 has been set up and is operative. The clamping pots 3a are held on the one hand by their bottom walls resting on the top closures 7 of the lower pots 3b, on the other hand by the wedging walls 16 of the fins 15b in contact with the portions of the side walls. 6a chucks 3a adjacent to the spacing / wedging portion 15.

The form of detail of the packaging 5 is adapted to the shape of the pots 3. The description of the packaging that has just been made is not excluded from others, in the case of jars 3 of different shapes.

On the other hand, and in the first place, the packaging 5 depends on whether the blank 1 is according to the first embodiment (for a pack with two layers of pots) or according to the second embodiment (for a pack with a single layer of pots). In the second place, the packaging depends on whether the blank 1 is intended for a pack 2 whose layer (or layers) of pots comprises four pots 3 or else a pack 2 comprising eight pots 3.

In the case of a pack 2 having a single layer of pots, the packaging formatted is, as a whole, similar to that of a pack 2 with two superposed layers, if not, first of all , that its dimension along the axis C is smaller so as to be adapted to the number of layers. On the other hand, the package 5 may not include openings 20.

In the case of a pack 2 whose layers of superposed pots comprise, for example, eight pots 3, the shaped packaging is, as a whole, similar to that of a pack 2 with two superimposed layers, if not is, first, that its transverse dimension is larger given the presence of additional pots.

The invention also relates to a pack 2, comprising a lower layer of pots two by two side by side and vis-à-vis and a layer of upper pots two by two side by side and vis-à-vis, positively spaced and calibrated, of types as they have been described.

In such a pack, the pots 3 are received by their bottom walls 6c on the base panel 12. The top wall 10c is applied to or adjacent to the top closure 7 of the packs 2 of the pack forming part of the upper layer , the wedging walls 16 are placed adjacent to the side walls 6a of the wedging pots 3a, in the vicinity of their top walls 6b, so as to ensure the spacing and wedging of these pots 3a in the vicinity of their walls. above 6b.

According to the embodiments, the pots 3 or not include a flange towards the opening. When the pots 3 comprise a flange, these flanges can, in the case of the pots of the upper layer of pots, cooperate with the cut-out concave portions 22b of the openings 20.

The wedging walls 16 are adapted to wedge the clamping pots 3a on their side walls 6a, in the vicinity of their top walls 6b.

By "wedging the clamping pots 3a on their side walls 6a", it should be understood that in the pack 2, the clamping pots 3a are prevented, at least to a certain extent, from moving relatively - inadvertently - With respect to the package 5, or to shock each other, because the side wall 6a of each clamping pot 3a is adjacent to a specific clamping wall 16 to this pot 3a.

By wedging the clamping pots 3a on their side walls 6a "in the vicinity of their top walls 6b", it should be understood that the part of the side wall 6a of each clamping pot 3a which, in the pack 2, is adjacent to the casting wall 16 considered is, for a substantial part, spaced apart from the top wall 6b in the axial direction of this pot 3a - between its top wall 6b and its top closure 7 - with a relatively small gap with respect to the gap between the bottom wall 6c and the top closure 7.

By the term "adjacent" concerning the side wall 6a of a shim pot 3a and the corresponding shimming wall 16, it should be understood that, depending on the circumstances - and especially the play between the part spacing / wedging 15 and the side wall 6a of a clamping pot 3a-, the side wall 6a of a clamping pot 3a is in contact with the corresponding clamping wall 16, with even - if necessary - a certain support force, so as to ensure the blocking stop of the clamping pot 3a in this position, or that the side wall 6a is only in the immediate vicinity of this clamping wall 16 - for example a fraction of millimeter or a few millimeters - so that the displacement of the clamping pot 3a is limited to the small spacing between the side wall 6a and the corresponding clamping wall 16, and that at the end of any displacement of the clamping pot 3a, the side wall 6a comes in contact with the wedging wall 16, so as to ensure the blocking stop of the clamping pot 3a in the end position of displacement.

The wedging walls 16 being adapted to wedge the clamping pots 3a, as it has just been exposed, they participate in that in the pack 2, the setting pots 3a can not, or can only little, move unintentionally or shock each other.

The shape, the arrangement, the dimensions of the constituent parts of the blank 1, the spacing / wedging portion 15, the arrangement, the dimensions of the pots 3 are in adequacy, so that in the shaped packaging 5 , the sidewalls 6a of the clamping pots 3a are adjacent to the clamping walls 16 as it has been exposed.
