System for maintaining a row of individual pots, blanks kit and packaging of individual pots

The invention relates to the field of packaging of individualized pots, in particular to facilitate placing on a shelf of a row of individualized pots.

A more specific subject of the invention is a system for holding a row of individualized pots, intended to facilitate shelving of a row of individualized pots, packaging for individualized pots comprising such a system for holding pots, a flat blanks kit intended for the formation of such a system for holding a row of individualized pots, a flat pots holding blank and a flat pots unlocking blank for such a blanks kit, a method for producing such packaging for individualized pots, a method for releasing individualized pots from such packaging for individualized pots and a line for producing such packaging for individualized pots.

An individualized pot, such as that considered, comprises a bottom wall, a side wall closed on itself, and a flange at one end of the pot. In a simple embodiment, the pot is in the form of a cylinder or truncated cone with a transverse flange towards its upper opening, a top closure like a flat cover can be secured to and on the flange. In other embodiments, the generatrix of the side wall is a line other than a straight line, having a more or less complex shape, and the directing curve is other than a circle, being for example a curvilinear square with rounded corners .

In one embodiment, such a pot is made of thermoformed plastic 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 state of the whole, 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 not being exhaustive.

In one embodiment, the pot is intended to receive a dose of such content for individual and unitary use, for example of the order of a hundred grams and, in this case, it may have a height of the order a few centimeters and fit sideways into a cylinder whose diameter is also of the order of a few centimeters. In other embodiments, the jar, intended for a mini-dose, is smaller or, on the contrary, intended for a larger dose, is larger.

To carry out the shelving of such individual jars, an operator takes for example the individualized jars in a transport container and arranges them and aligns one by one on a shelf of a supermarket shelf to form one or more row (s) individualized pots. Such an operation requires a certain amount of time on the part of the operator, in particular because he risks overturning the pots if he proceeds to shelving too quickly.

Alternatively, there are known so-called "ready-to-sell" boxes or racks usually made of cardboard or plastic, which are transport containers suitable for being placed on the shelf and visible to a consumer. Such boxes or racks receive pots arranged in several columns and several rows, said pots being arranged on a body bottom and usually contained laterally by vertical rims of low height surrounding the body bottom and making it possible to avoid tilting the pots out of the box when shelving. These boxes or rack thus allow an operator to simultaneously place a large quantity of pots on the shelf, thereby reducing the time and / or the number of operators required for this operation.

These boxes and racks cannot in practice be used to place a single row of individualized pots on the shelves because the aspect ratio of the box makes handling difficult in this case. The individualized pots are only held by the low rims delimiting the bottom of the body, and are not stabilized by the presence of other pots. The pots may thus tip out of the box during shelving.

Furthermore, it is known to maintain a portion of the individualized pots, for example a flange or a flared base of the pots, to facilitate the handling of the individualized pots, in particular when said pots are aligned in a longitudinal direction to form at least one row of individualized pots. Thus, for example, documents US 2,331,038 and US 2,752,080 disclose systems for holding a row of individual pots, the pots being of the type having a bottom wall, a side wall closed on itself and a flange at one end of the pot. Such a system for holding a row of individualized pots comprises a set for holding pots extending in a longitudinal direction, and comprising:

• a plurality of gripping surfaces capable of coming to bear against the flanges of the pots of a row of individualized pots, • a plurality of gripping counter surfaces capable of coming to bear against the pots of the row of individualized pots so that said pots are sandwiched and held between the gripping surfaces and the gripping counter surfaces of the jar holding blank.

Such an assembly can be arranged on a shelf with the pots accessible to a consumer. The consumer wishing to take a pot from the row can then exert a force on the pot sufficient to separate it from the pot holding assembly.

However, such systems for maintaining a row of individualized pots have drawbacks. Thus, it is not easy to calibrate the effort to be overcome in order to separate a pot from the jar holding assembly so that, on the one hand, the jars are sufficiently maintained by the jar holding assembly. jar to facilitate the shelving of the row of individualized jars, and on the other hand, the jars are sufficiently loose in the jar holding assembly so that consumers of all ages and physical strength can easily take the jars from the row of pots. Furthermore, such systems are not easily adaptable in the case where the flanges of the pots are arranged at the upper end of the pots opposite the surface of the supermarket shelf. In this case, in fact, the holding system is interposed between the jar and the consumer and, on the one hand, makes it difficult to access the jars, and on the other hand, complicates shelving and removal by imposing a greater pot holding force.

The problem underlying the invention is thus to propose systems for maintaining a row of individualized pots facilitating the shelving of small quantities of individualized pots, in particular a row of individualized pots, while allowing a withdrawal subsequent easy pots of the row of individualized pots shelved. This problem is posed in combination with that of a reduced cost of the jar holding system and of packaging of a row of individual jars, of high machinability for high rates, with a method of manufacturing maintenance of jars and packaging of a row of individualized safe jars and a production line which avoids the penalizing complexities.

Below is a detailed description of several embodiments of the invention with examples and reference to the drawings.

Figure 1 illustrates a package 1 of a row of individualized pots according to the invention. Such packaging 1 comprises a system 2 for holding pots and a row 3 of individualized pots 4.

The individualized pots 4 are of the type having a bottom wall, a side wall closed on itself and a flange at one end of the pot. The pots 4 are aligned in a longitudinal direction X to form a row 3 of individualized pots.

By "pot" should be understood a container as it has been described in the introductory part and the characteristics of which do not need to be described again here, it being recalled that such a pot 4, which has a certain resistance allowing it to be self-supporting, comprises a bottom wall 5, a side wall 6 closed on itself around a vertical direction Z with an opening 7 at an upper end 4a of the pot and the bottom wall 5 at one end lower 4b of the pot, opposite, and a flange 8 projecting radially from the vertical direction Z at one of the upper and lower ends of the pot. The pot can also include a top closure 9, such as, typically, a cover placed on and secured to the opening 4c. In the context of the invention, the pots 4 of a row 3 are similar, very specially identical, and they are filled with a certain content, identical or not for the different pots 4, and closed.

By "a row of individualized pots" means a set of pots juxtaposed to each other in the longitudinal direction and comprising a single layer of pots in a vertical direction perpendicular to the longitudinal direction. By “individualized pots”, it is meant that the pots are pots separated from each other and are not connected to each other in particular by their flanges 7.

The system 2 for holding a row of individualized pots is illustrated in more detail in FIG. 2 and comprises a set for holding pots 10 and a set for unlocking pots 11. The set for holding pots 10 and the set for unlocking pots 11 extend in the longitudinal direction X and are superimposed on each other.

The jar holding assembly 10 may in particular comprise a jar holding blank. In particular, the jar holding assembly 10 can be formed by a single blank or several blanks joined together so as to form a unitary assembly. The jar holding blank (s) are for example made of cardboard or the like, in particular corrugated cardboard.

Likewise, the jar unlocking assembly 11 may include a jar unlocking blank. In particular, the pot unlocking assembly 11 can be formed by a single blank or several blanks joined together so as to form a unitary assembly. The jar unlocking blank (s) are for example made of cardboard or the like, in particular corrugated cardboard.

By “cardboard”, it is necessary to understand a layered material, such as that commonly used or adapted to a blank having the indicated destination. Advantageously, such cardboard can be relatively rigid, so when it is folded in a U to support the weight of a row of pots when it is grasped at a point, for example in the middle. The cardboard is thus for example a corrugated cardboard, that is to say consisting of several sheets of fluted paper glued together between sheets of planar paper. The cardboard blanks can be folded in the place of grooved lines, provided for this purpose as detailed below. By "cardboard or the like" is meant that materials other than cardboard, having rigidity and strength characteristics as described above, can also be used, for example injected or thermoformed plastic.

The jar unlocking assembly 11 can be moved relative to the jar holding assembly 10 between a jar holding position illustrated in FIGS. 2A to 2C and an unlocking position illustrated in FIGS. 3A to 3C. For this, the pot unlocking assembly is for example adapted to slide relative to the pot holding assembly in the longitudinal direction X between the holding position and the unlocking position in the general direction indicated by the arrow L of Figure 3A.

Furthermore, the pot holding assembly 10 includes a plurality of gripping surfaces 12 and a plurality of gripping counter surfaces 13.

Reference is made more particularly to the system 2 for holding a row of individualized pots illustrated in FIG. 2B, in which the pot unlocking assembly 11 is in the pot holding position.

As can be seen in FIG. 2C, the gripping surfaces 12 come to bear on the flanges 8 of the pots 4, and the gripping counter surfaces 13 come to bear against the pots 4, in particular on the ends of the pots 4 at the location of which the flanges 8 of the pots are present. The support exerted by the gripping surfaces 12 on the pots 4 and the counter-pressure exerted by the gripping counter surfaces 13 on the pots 4 are such that the pots 4 are sandwiched and held between the gripping surfaces 12 and the gripping counter surfaces 13, that is to say in particular sandwiched and held at their end 4a having the flange 8.

By “the pots are sandwiched and held between the gripping surfaces and the gripping counter surfaces”, it is meant that the gripping surfaces 12 and the gripping counter surfaces 13 exert forces on the pots 4 of the row of pots such that respective components of said supports and counter-supports are in opposition and make it possible to maintain the pots 4 between the gripping surfaces 12 and the gripping counter surfaces 13. For this, the gripping surfaces 12 and / or the counter surfaces gripping means 13 can in particular exert elastic supports and counter-supports on the pots 4.

Furthermore, by “coming to exert a support” and “coming to exert a counter-support”, it is meant to apply a force directly, that is to say in intimate contact, or else by means of a part performing force transmission, for example by means of the jar unlocking assembly 11, in particular of the base 19 of the jar unlocking blank 11, as explained below.

The gripping surfaces 12 and the gripping counter surfaces 13 may be substantially parallel to one another and opposite. The gripping surfaces 12 and the gripping counter surfaces 13 can extend in a horizontal plane XY perpendicular to the vertical direction of extension of the pots 4.

To this end, the jar holding blank 10 of the jar holding assembly 10 can be set in volume so as to present, perpendicular to the longitudinal direction, a U-shaped section adapted to come and surround one end of each jar 4 of row 3 of individualized pots. The U-shaped section of the jar holding blank 10 can in particular surround the end of each jar 4 at the place, or in the vicinity, of which the flange 8 extends.

Thus, the jar holding blank 10 may comprise a base 14 and two lateral wings 15. The base 14 may extend along a horizontal plane XY, perpendicular to the vertical direction Z of extension of the jars 4. The lateral wings 15 can be placed on either side of the base in a transverse direction Y of the horizontal plane XY, perpendicular to the longitudinal direction X. The lateral wings 15 can be inclined relative to the base 14, in particular extending along the vertical direction Z and be substantially perpendicular to said base 14 as can be seen in FIG. 2C.

By “the lateral wings can be substantially perpendicular to said base”, it is meant that the lateral wings can have an angle with the base of the order of 90 °, for example between 60 and 120 °, around the longitudinal direction X. The angle between the lateral wings and said base can in particular be adapted to the shape of the pots and to the relative extension of the base 14 and the flanges 8 in the transverse direction Y.

The base 14 of the jar holding blank 10 may have a generally rectangular shape with an extension in the longitudinal direction X of the order of the length of the row 3 of jars 4 and an extension in the transverse direction Y, perpendicular to the longitudinal direction X, less than or equal to an overall dimensions of the pots 4 in said transverse direction Y. The base 14 of the jar holding blank 10 can in particular be continuous and in one piece.

The gripping surfaces 12 are then for example formed in the lateral wings 15 of the jar holding blank 10 and the gripping counter surfaces 13 are formed in the base 14 of the jar holding blank 10.

FIGS. 2B illustrate in more detail the lateral wings and the base of the jar holding blank visible in FIG. 2A.

The side wings 15 of the jar holding blank 10 extend substantially along a vertical plane XZ comprising the longitudinal direction and the vertical direction of extension of the jars 4. The side wings 15 may have a vertical extension less than a vertical extension of the pots 4, for example between one third and two thirds of the vertical extension of pots 4, so that the pot holding blank 10 surrounds only one end of pots 4 and leaves the other end of pots 4 free and visible. The lateral wings 15 of the jar holding blank 10 can in particular be each continuous and in one piece. The lateral wings 15 can be articulated and secured to the base 14 by grooved lines 26 respectively extending in the longitudinal direction X and forming the transverse edges of the base 14.

The lateral wings 20 of the jar unlocking blank 11 can have dimensions and orientations similar to those of the lateral wings 15 of the jar holding blank 10.

The lateral wings of the jar unlocking blank and the lateral wings of the jar holding blank may for example have a vertical extension of the order of 40 to 50 millimeters. The base 14 of the jar holding blank 10 and the base of the jar unlocking blank 11 may have an extension in the transverse direction Y of the order of 60 to 100 millimeters and an extension in the longitudinal direction of 300 to 600 millimeters long, allowing for example to accommodate five to six pots.

In general, the jar unlocking blank 11 and the jar holding blank 10 have similar dimensions, orientation and general configuration, so that the dimensions and orientations exposed for the jar holding blank 10 are also applicable to the blank for unlocking pots 11, unless expressly stated.

The lateral wings 15 comprise a plurality of centering lunettes 16. The centering lunules 16 are recesses in the lateral wings 15 adapted to be penetrated by portions of the flanges 8 of the pots 4 of the row of individualized pots 3.

The extension in the transverse direction Y of the base 14 can in particular be strictly less than the size of the flange 8 of the pots 4 in said transverse direction Y, so that the flanges of the pots 4 penetrate over a certain distance through the centering bezel 16.

The centering bezels 16 may have an extension, in the longitudinal direction X adapted so that the leading edges 8c of the flanges 8 of the pots 4 come close to the edges 16a of the centering lunules. In this way, the movement of the pots 4 in the longitudinal direction X and the transverse direction Y can be limited to the small spacing between the leading edge 8c of the flange 8 and the edge 16a of the corresponding centering bezel 16. The cooperation of the gripping surfaces 12 and gripping counter surfaces 13 also realizing, when the unlocking assembly 11 is in the jar holding position, holding and immobilizing in the vertical direction Z, the movement of the jars 4 can be limited or prevented in all three directions of space. Manipulation of the row of pots 4 is therefore possible in an easy manner, simply by manipulating the pot holding system 2.

As can be seen in FIG. 2C, the gripping surfaces 12 are for example formed by gripping tabs 17 of the jar holding blank 10, extending within the centering lunules 16, in particular in the vertical direction Z extension pots 4.

The gripping tabs 17 of the jar holding blank 10 extend within the centering lunettes 16 of the jar holding blank 10, from the lateral wings 15 of the jar holding blank 10 and in the direction of the base 14 of the jar holding blank 10. Thus, if the lateral wings 15 of the jar holding blank 10 extend downward from the base 14 of the jar holding blank 10, the gripping tabs 17 can extend towards the high and vice versa.

The gripping surfaces 12 can in particular be formed by end edges 17a of said gripping tabs 17 as illustrated in FIG. 2C. Thus, the gripping tabs 17 can come to bear at their extremal edge 17a with a surface 8a, 8b of the flanges 8 of pots 4.

The gripping surfaces 12 can thus have a width of the order of the thickness of the blank, for example a few millimeters, and a length several times greater, of ten or twenty millimeters for example, or a surface of a hundred square millimeters for example.

The gripping counter surfaces 13 may have a larger surface than the gripping surfaces 12, being formed in the base 14 of the blank 10, for example an area of several square centimeters, at least 4 square centimeters. The gripping counter surfaces 13 may not be delimited and separated from one another on the base 14 of the jar holding blank 10 but simply each defined by the shape of a jar end 4 adjacent to the base 14. The gripping counter surfaces 13 can thus be connected together and form a continuity solution on the base 14.

It is further understood that the gripping surfaces 12 are in intimate contact with the flanges 8 of the pots 4. The gripping surfaces of the jar holding blank are in particular in contact with the surfaces 8a, 8b of the flanges 8 opposite the end of each pot 4 surrounded by the U-shaped section of the pot holding blank 10. The gripping counter-surfaces 13 then exert a counter-support on the end 4a, 4b of each pot 4 which is surrounded by the section in U of the jar holding blank 10.

Thus in the example of FIG. 2A, the upper end 4a of each pot 4 of the row 3 of pots is surrounded by the U-shaped section of the jar holding blank 10 and the gripping surfaces of the jar holding blank are then in contact with lower surfaces 8b of the flanges 8 while the gripping counter-surfaces 13 exert a counter-support on the upper end 4a of each pot 4.

In the example of FIG. 5, the lower end 4b of each pot 4 of the row 3 of pots is surrounded by the U-shaped section of the pot holding blank 10 and the gripping surfaces of the pot holding blank are then in contact with upper surfaces 8a of the flanges 8 while the gripping counter-surfaces 13 exert a counter-support on the lower end 4b of each pot 4.

In the examples of FIGS. 2A to 2C, the pot unlocking assembly 11 is in the pot holding position.

As we have seen, in the jar holding position, the jar unlocking assembly 11 leaves the plurality of gripping surfaces and the plurality of gripping counter surfaces free to sandwich and hold the jars of the row of individualized pots. It is then possible for an operator to easily handle the individualized row of pots by means of the pot holding system 2, to which the pots 4 are held firmly.

Reference is now also made to FIGS. 3A to 3C which illustrate the pot unlocking assembly 11, this time in the unlocking position.

In the unlocking position, the pot unlocking assembly 11 separates the pots4 at least one from among the plurality of gripping surfaces 12 and the plurality of gripping counter surfaces 13. In this way, the pots 4 of the row 3 of individualized jars are released from the jar holding assembly 10. In particular, the jar unlocking assembly 11 can separate the jars from the plurality of gripping surfaces 12 as illustrated in FIG. 3C.

For this, the pot unlocking assembly 11 includes a plurality of unlocking surfaces 18 illustrated in particular in FIG. 3B.

The unlocking surfaces 18 are respectively associated with the gripping surfaces 12.

By "unlocking surfaces are respectively associated with the gripping surfaces", it is meant that with each gripping surface is associated at least one unlocking surface.

In the unlocking position of the pot unlocking assembly 11, the unlocking surfaces 18 are interposed between the flanges 8 of the pots 4 and the gripping surfaces 12. The pots 4 of the row 3 of individualized pots are thus released from the jar holding assembly 10 and can be removed or the jar holding system 2 can be removed from the row of individualized jars.

The pot unlocking assembly 11 can for example interact with the pot holding assembly 12 in the following manner.

A jar unlocking blank 11 of the jar unlocking assembly 11 can be set in volume so as to present, perpendicular to the longitudinal direction, a U-shaped section adapted to come and surround one end of each jar 4 of row 3 individualized pots. The U-shaped section of the jar unlocking blank 11 can in particular surround the end of each jar 4 at the place, or in the vicinity, of which the flange 8 extends.

Thus, the jar unlocking blank 11 may comprise a base 19 and two lateral wings 20. The base 19 may extend along a horizontal plane XY, perpendicular to the vertical direction Z of extension of the jars 4. The lateral wings 20 can be placed on either side of the base in a transverse direction Y of the horizontal plane XY, perpendicular to the longitudinal direction X. The lateral wings 20 can be inclined relative to the base 19, in particular extending along the vertical direction Z, substantially perpendicular to said base 19 as can be seen in FIG. 2C.

The jar holding blank 10 and the jar unlocking blank 11 can thus have substantially similar volume conformations, so that they can be superimposed on each other.

The jar unlocking blank 11 can thus be sandwiched between the jar holding blank 10 and the jars 4 of the row 3 of individualized jars as illustrated in FIG. 2C.

The base 19 of the jar unlocking blank 11 then comes into contact with the end of each jar of the row of individual jars surrounded by the U-shaped section of the jar unlocking blank 11. The base 19 of the unlocking blank of pots 11 can also be in contact with the base 14 of the pot holding blank 10.

Thus, the gripping counter-surfaces 13 of the pot holding assembly 10 can exert a counter-support on the ends 4a of the pots 4 of the row 3 of pots via the base 19 of the unlocking blank of pot 11.

The unlocking surfaces 18 can be formed in the lateral wings 20 of the jar unlocking blank 11 as illustrated in FIG. 2A.

For this, the lateral wings 20 of the pot unlocking blank 11 comprise for example a plurality of openings 21. The lateral wings 20 also comprise a plurality of unlocking tabs 22 each extending within an opening 21, by example in the vertical direction Z of extension of the pots 4, in particular upwards.

The openings 21 of the lateral wings 20 of the pot unlocking blank 11 are penetrated by portions of the flanges 8 of the pots 4 of the row of individualized pots.

The unlocking surfaces 18 are then formed on the unlocking tabs 22 of the jar unlocking blank 11. The unlocking surfaces 18 can for example be formed by extension surfaces 22b of said unlocking tabs 22 directed towards the outside of the U-shaped section of the jar unlocking blank 11.

The unlocking tabs 22 of the jar unlocking blank 11 may in particular extend, within the openings 21 of the jar unlocking blank 11, from the lateral wings 20 of the jar unlocking blank 11 and in the direction of the base 19 of the jar unlocking blank 11. Thus, if the lateral wings 20 of the jar unlocking blank 11 extend downward from the base 19 of the jar unlocking blank 11, the unlocking tabs 22 can extend upwards and vice versa.

The unlocking tabs 22 can respectively be associated with the gripping tabs 17.

The term “respectively associated” means that each gripping tab is associated with at least one unlocking tab.

More specifically, the jar holding blank 10 may comprise, for each individualized jar 4 of the row of jars, two centering bezels 16, formed respectively in each of the lateral wings 15 of the jar holding blank 10, and two tabs of gripping 17, also formed respectively in each of the lateral wings 15 of the jar holding blank 10. Similarly, the jar unlocking blank 11 may comprise, for each jar 4 individualized from the row of jars, two openings 21, made respectively in each of the lateral wings 20 of the jar unlocking blank 11, and two unlocking tabs 22, also formed respectively in each of the lateral wings 20 of the jar unlocking blank 11.

The openings 21 and centering rings 16 associated with each individualized pot 4 of the row of pots can accommodate portions of the collar 8 of said pot 4 opposite in the transverse direction Y perpendicular to the longitudinal direction X. The associated gripping tabs 17 said pot 4 can also come from either side of said pot 8 in the transverse direction Y.

As will be seen, the openings 21 may have a greater extension than an extension of the centering lunules 16 in the longitudinal direction X, so as to allow movement of the unlocking blank 11 between the jar holding position and the position of unlocking pots. Thus for example, if the unlocking blank moves over a distance D in the longitudinal direction X between the jar holding position and the jar unlocking position, the openings 21 may have a greater extension at least of said distance D to the extension of the centering lunules 16 in the longitudinal direction X.

The passage of the pot unlocking assembly 11 from the pot holding position to the pot unlocking position is carried out as follows.

As can be seen in FIG. 2A, when the jar unlocking blank 11 is in the jar holding position, the unlocking tabs 22 of the jar unlocking blank 11 extend through the centering rings 16 of the jar holding blank 10 and near the gripping tabs 17 of the jar holding blank 10.

And, when the jar unlocking blank 11 comes into the unlocking position, the unlocking tabs 22 are interposed between the gripping tabs 17 and the flanges 8 of the jars 4 of the row 3 of individual jars.

To this end, each unlocking tab 22 has a lateral leading edge 22a while the gripping tab 17 associated with said unlocking tab 22 has a lateral edge 17b facing the lateral leading edge 22a.

By "a lateral edge opposite the lateral leading edge" is meant that, when the jar holding system 2 is in the jar holding position, the lateral edge faces said lateral leading edge. Thus, if the lateral leading edge is a straight edge of an unlocking tongue (the term "right" being defined with respect to the longitudinal direction), the lateral edge will then be a left edge of the gripping tongue (the term "left" being defined as the opposite direction of the same longitudinal direction) and vice versa.

The lateral edge 17b of the gripping tongue 17 can in particular terminate at the location of the gripping surface 12a, in particular when said gripping surface 12 is formed by an extremal edge 17a of the gripping tongue 17.

The lateral leading edge 22a of the unlocking tongue 22 extends beyond the lateral edge 17b of the associated gripping tongue 17.

By "extends beyond", it is meant that, according to the direction of extension of the unlocking and gripping tabs, the lateral leading edge of the unlocking tab protrudes beyond the lateral edge of the gripping tab. For example, if the direction of extension of the unlocking and gripping tabs is the vertical direction Z, in particular upwards in the vertical direction Z, the lateral leading edge of the unlocking tab may extend higher than the lateral edge of the grip tab.

In this way, when the pot unlocking assembly 11 is in the pot holding position illustrated in FIG. 2A, the gripping surfaces 12 formed on the end edges 17a of the gripping tabs 17 can be in contact with the surfaces. 8b of the flanges 8 of the pots and, when the pot unlocking assembly is in the unlocking position illustrated in FIG. 3A, the unlocking tabs 22 can come into contact with the leading edges 8c of the flanges 8 of the pots 4 and be interposed between the gripping tabs 17 and the flanges 8 of the pots 4.

To facilitate the movement of the unlocking assembly, when the jar unlocking assembly 11 is in the jar holding position, the unlocking tabs 22 of the jar unlocking blank can be arranged at least partially between the edges 8c of the flanges of the pots and the gripping tabs 17.

As illustrated in FIG. 3A, the movement between the holding position and the unlocking position of the jar unlocking blank 11 can be achieved by sliding in the longitudinal direction X relative to the jar holding blank 10.

Additionally, the lateral leading edges 22a of the unlocking surfaces 22 can be inclined relative to the lateral edges 17b facing the gripping tabs 17 associated with each unlocking tab 22. The lateral leading edges 22a of the unlocking surfaces 22 may more precisely be inclined with respect to a vertical direction Z perpendicular to the longitudinal direction X of movement of the jar unlocking blank 11 with respect to the jar holding blank 10.

In this way, the unlocking tabs are able to come gradually to come between the gripping tabs and the flanges of the pots of the row of individualized pots when the pot unlocking assembly is moved from the pot holding position to the unlock position.

The jar unlocking blank 11 can also include at least one stop tab 23. The jaw locking tab 23 can extend from the base 19 of the jar unlocking blank 11, through at least one opening 21 of the jar unlocking blank 19 and through at least one centering ring 16 of the jar holding blank 10.

The stop tab 23 is adapted to abut against an edge 16a of said centering ring 16 of the jar holding blank 10. In this way, it is possible to limit the movement of the jar unlocking blank relative to the blank holding pots between the holding position and the unlocking position.

Finally, one of the jar holding blank 10 and the jar unlocking blank 11 may include a pull tab 24 illustrated in FIG. 3A, placed at a longitudinal end of said blank. In the example of FIG. 3A, the jar unlocking blank 11 has said pull tab 24.

The pull tab 24 makes it easy to slide the jar holding blank 10 and the jar unlocking blank 11 relative to each other so as to move the jar unlocking assembly between the holding position and the unlock position.

The pull tab 24 may in particular have a central opening 24a making it possible to give access to the flanges 8 of the pots of the row of individualized pots sandwiched and held by the jar holding blank 10. The central opening 24a can for example have the width of a human finger in the transverse direction. It is thus possible for an operator moving the jar unlocking fan relative to the jar holding blank to manually hold the jars 4 during this operation by inserting a finger into the central opening 24a of the pull tab 24.

FIG. 2A thus illustrates a packaging of a row 3 of individualized pots comprising a system for holding pots 2 as described above and a row 3 of individualized pots 4, the pots 4 being sandwiched and held between the surfaces gripping 12 and the gripping counter surfaces 13 of the jar holding assembly 10.

To free the individualized jars from such packaging 1, an operator can thus:

- place the packaging of individualized pots 1 on a support S, for example a supermarket display,

- maintain the jar holding assembly 10 and / or the jars 4, for example by introducing a finger in the central opening 24a of the pull tab 24,

- exerting a force on the unlocking assembly 11 so as to move the potsl unlocking assembly 1 relative to the jar holding assembly 10 from the holding position to the unlocking position, for example by exerting a force on the pull tab 24.

In a first embodiment of the invention, illustrated in FIG. 2A, the packaging 1 of individualized pots is placed on a support S so that the pots 4 of row 3 rest on the support S at one end 4b pots opposite the collar 3, in particular in the case where the collar is placed near the opening 4c of the pots 4.

In this embodiment, the holding system 2 of the packaging 1 can then also be removed by letting the pots 4 rest on the support S as illustrated in FIG. 4. The pots 4 are then available for withdrawal by a consumer.

In a second embodiment illustrated in FIG. 5, the packaging 1 is placed on a support S so that the pots 4 of row 3 rest on the support S by means of the pot holding system 2 to one end 4b of the pots having the collar 3, for example in the case where the collar 8 is placed opposite the opening 4c of the pots 4.

In this embodiment, the holding system 2 can then be left between the pots 4 and the support S after implementation of the release process. The jars 4 are then based on the jar holding system 2 unlocked and are also available for sampling by a consumer.

Note that the movement of the pot holding assembly 10 from the holding position to the unlocking position is one-way. That is to say, it is better to flatten the jar holding blank if you want to rebuild the system in the holding position.

Referring now to FIGS. 6A to 6C and 2A, a jar holding system 2 according to the invention as illustrated in FIG. 2A can be produced from a kit 25 of flat blanks as illustrated .

Such a kit 25 comprises a blank for holding the pots 10 flat and a blank for unlocking the pots 11 flat.

By "flat" in the expression "flat blank", it should be understood that the blank is deployed, so as to be at least substantially in one and the same plane P. Unless the term " blank ", without further details, should be understood as targeting the blank in volume as described above, as opposed to the flat blank.

The jar holding blank 10 flat and the jar unlocking blank 11 flat respectively have a generally rectangular shape extending substantially in a longitudinal direction X and to a lesser extent in a transverse direction Y perpendicular to the longitudinal direction.

The jar holding blank 10 and the jar unlocking blank 11 are respectively limited by two free edges in the longitudinal direction and two free edges in the transverse direction. In the embodiment shown, the free edges are rectilinear, but in other embodiments, they may not be, being for example scalloped. The jar holding blank 10 and the jar unlocking blank 11 are symmetrical or substantially symmetrical with respect to a longitudinal central axis.

The jar holding blank 10 and the jar unlocking blank 11 are made of cardboard or the like as indicated above.

The jar holding flat 10 has a base panel 14 respectively surrounded on either side, in the transverse direction Y, by two respective side wing panels 15. The base panel 14 and the panels respective side wings 15 have a substantially rectangular shape.

By “panel”, it is necessary to understand a flat piece in the form of a layer, of cardboard in this case, delimited by a border comprising grooved lines and / or cut lines.

The base panel 14 is separated from the side wing panels 15 by grooved or cut lines 26 extending in the longitudinal direction X over all, or a majority of, the longitudinal extension of the base panel 14 and forming the edges transverse of said base panel 14, otherwise defined at the longitudinal ends by the free edges of the jar holding blank 10. The lines 26 allow the folding of the side wing panels 15 relative to the base panel 14 so as to form a blank holding pots in volume 10 having a U-shaped section perpendicular to the longitudinal direction X as illustrated in FIG. 2A.

The base panel 14 of the jar holding blank 10 flat corresponds to the base 14 of the jar holding blank 10 in volume. The unique reference 14 is therefore given to these elements. Similarly, the side wing panels 15 of the jar holding blank 10 flat correspond to the side wings 15 of the jar holding blank 10 in volume. The unique reference 15 is therefore given to these elements. The base panel 14 and the base 14 are identical apart from their position in space respectively to the side wing panels 15 and side wings 15. Similarly, the side wing panels 15 and the side wings 15 are identical apart from their position in space respectively at the base panel 14 and base 14.

The side wing panels 15 of the jar holding blank comprise a plurality of centering lunettes 16 and a plurality of gripping tabs 17 extending within the centering lunules 16.

The jar unlocking blank 11 also comprises a base panel 19 respectively surrounded on either side, in the transverse direction Y, by two panels of respective side wings 20. The base panel 19 and the side wing panels 20 have a substantially rectangular shape.

The base panel 19 of the jar unlocking blank 11 is separated from the side wing panels 20 by grooved or cut lines 27 extending in the longitudinal direction X over all, or a majority of, the longitudinal extension of the panel base 19 and forming the transverse edges of said base panel 19, otherwise defined at the longitudinal ends by the free edges of the jar unlocking blank 11. The lines 26 allow the folding of the side wing panels 20 relative to the base panel 19 so as to form a blank for unlocking pots 11 in volume having a U-shaped section perpendicular to the longitudinal direction X as illustrated in FIG. 2A.

The side wing panels 20 of the jar unlocking blank 11 have a plurality of openings 21 and a plurality of unlocking tabs 22 extending within the openings 21.

The jar unlocking blank 11 can also include at least one stop tab 23. The jaw tab 23 extends from the base panel 19 of the jar unlocking blank 11 and through at least one opening 21 of the jar unlocking blank 11.

By "extends from the base panel and through at least one opening", it is meant that said stop tab protrudes, in the transverse direction, from the base panel otherwise of substantially rectangular shape.

As indicated above concerning the jar holding blank 10, the base panel 19 of the jar unlocking blank 11 flat corresponds to the base 19 of the jar unlocking blank 11 in volume. The unique reference 19 is therefore given to these elements. Similarly, the side wing panels 20 of the jar unlocking blank 11 flat correspond to the side wings 20 of the jar unlocking blank 11 in volume. The unique reference 20 is therefore given to these elements. The base panel 19 and the base 19 are identical, apart from their position in space respectively with the side wing panels 20 and side wings 20. Similarly, the side wing panels 20 and the side wings 20 are identical, apart from their position in space respectively at the base panel 19 and base 19.

The gripping tabs 17 and the unlocking tabs 22 extend in the transverse direction Y. The gripping tabs 17 and the unlocking tabs 22 for example have a substantially rectangular or trapezoidal shape.

The gripping tabs 17 can be defined in the side wing panels 15 of the jar holding blank 10 by grooved lines 28, in particular defined by the cut lines with the exception of a grooved line 28 for each tongue of gripping 17, so that it can be folded relative to said side wing panels 15. The grooved lines 28 can extend in the longitudinal direction X, so as to allow pivoting of the gripping tabs 17 around the longitudinal axis X as seen in Figure 3C. In this way, it is possible to easily move aside the gripping surfaces 12 of the flanges 8 of the pots 4 during the passage of the unlocking assembly 11 from the pot holding position to the unlocking position.

Conversely, the unlocking tabs 22 can be rigidly formed in the side wing panels 20 of the jar unlocking blank 11, that is to say being delimited in said blanks without grooved lines. In this way, the unlocking tabs 22 are capable of exerting more forces on the gripping tabs 17 in order to separate the gripping surfaces 12 from the flanges 8 of the pots 4 during the passage of the unlocking assembly 11 from the holding position. of pots in the unlocked position.

The unlocking tabs 22 of the jar unlocking blank 11 are at least partially defined by cut lines 29 penetrating into the base panel 19 of the jar unlocking blank 11.

By “cut lines penetrating into the base panel”, it is meant that said cut lines form a biting indentation in said base panel otherwise of substantially rectangular shape.

In this way, when the jar unlocking blank 11 is formed in volume and has a U-shaped section perpendicular to the longitudinal direction X, the unlocking tabs 22 extend, in the openings 21 of the jar unlocking blank, beyond the base 19 of the jar unlocking blank 11.

The centering lunules 16 and the openings 21 have for example a general shape of rectangle, rounded rectangle or half-moon. Thus, for example, a rectilinear edge of the openings 21 can be formed by a cut line delimiting a base panel 19 of the jar unlocking blank 11 and a cut line penetrating into a side wing panel 20 of the jar unlocking blank 11, otherwise substantially rectangular. The centering bezels 16 can be formed by a cut line penetrating into a base panel 14 of the jar holding blank 10 and a cut line entering into a side wing panel 15 of the jar holding blank 10 .

The cut lines, respectively of the centering lunules 16 and of the openings 21, penetrating into a side wing panel can in particular be interrupted, respectively, by a gripping tongue 17 and an unlocking tongue 22.

The blanks 10, 11 of the blank kit 25 can be produced by cutting and creasing cardboard plates according to means known elsewhere. The cut lines indicated above are formed by using a cutting tool. The grooved lines indicated above are also well known in the field of packaging and cardboard and allow relative folding of two adjacent panels at a predefined location. Such grooved lines are formed by using a creasing tool. It is understood that the expression "grooved line" must be understood in the broadest sense as meaning that the line is suitable and intended for the relative folding of two adjacent panels.
