Description

The present invention relates to a packaging essentially consisting of a base produced by cutting and folding a blank of material such as cardboard, and a bell which can be produced for example from thermoformed plastic.

Such packaging is known for example from document FR 2 989 669 A1, in which the base comprises a base base, two first flaps and two second flaps. The flaps are each articulated on the base of the base between a substantially flat storage position and a position of use in which the flaps are substantially perpendicular to the base of the base. The bell comprises a bell bottom and a peripheral wall with four opposite sides two by two and substantially perpendicular to the bell bottom.

In the position of use, the bell rests by the lower edge of its peripheral wall on the base of the base, two first flaps of the base are engaged inside the bell along the inner face of two first opposite opposite sides corresponding to the bell, while two second flaps of the base are arranged against the exterior surface of two opposite sides of the bell, and are secured to said exterior surface by bonding. The bonding is carried out according to bonding zones delimited from the second flaps, said zones each being surrounded by a precut. To open the packaging, the user cuts the second base flaps according to the precuts.

A first drawback of such a known packaging is the need to apply glue to the bonding areas when packaging a product in the packaging. This significantly increases the cost of using the packaging, due to the need to add a quantity of glue, and the need to provide specific sizing means for packaging the product.

A second drawback of such a known packaging is the difficulty of separating, for recycling after use, on the one hand the material constituting the bell, and on the other hand the material constituting the base, because the bonding zones cut from the base remain glued to the bell.

A problem proposed by the present invention is therefore to design a new packaging structure which does not require the use of adhesive means for securing the bell on the base, which thus makes it possible to reduce the cost of using the packaging and to facilitate the subsequent recycling of the materials making up the packaging.

7219FDEP.docx

Simultaneously, the invention aims to ensure reliable attachment of the bell on the base to prevent untimely separation of the bell away from the base despite the absence of bonding means. Such reliable joining is indeed necessary insofar as the packaging must be able to be handled without risk of opening by gripping along its opposite side faces.

To achieve these and other objects, the invention provides a package comprising a base and a bell, the base having a base base, two first flaps and two second flaps, said flaps each being articulated on the base between a position of substantially flat storage and a position of use in which the flaps are substantially perpendicular to the base of the base and in which said two first flaps are opposite one another and said two second flaps are opposite one to the other other, the bell having a bell bottom and a peripheral wall with four opposite sides two by two and substantially perpendicular to the bell bottom, in which, in the position of use:

- the bell rests by a free edge of its peripheral wall on the base of the base,

- said first two flaps of the base are engaged inside the bell along the interior face of two corresponding first opposite opposite sides of the bell,

- Said two second flaps of the base are arranged against the outer surface of the bell, and are secured to said outer surface.

The invention further provides that:

- said two second flaps of the base are detachably secured to said outer surface of the bell by snap-fastening means,

- The bell comprises protective means which at least partially obscure the edges of said two second flaps of the base.

The purely mechanical locking means avoid the use of glue. Simultaneously, the protective means avoid gripping or catching the edges of the second base flaps which could, inadvertently, cause the release of the second base flaps away from the latching means, and therefore the separation of the bell and the base.

According to an advantageous embodiment, the protection means may include recesses provided in the external surface of the bell, recesses in which said two seconds engage.

72î9FDEPdocx flaps of the base so as to make the side edges of said second flaps of the base inaccessible.

In practice, we can predict that:

- the recesses are each limited by a projecting peripheral rim,

said peripheral edge has a height greater than or equal to a thickness of the second corresponding base flap,

- Said peripheral rim follows the outline of the second corresponding base flap at a slight distance.

In this way, between the peripheral edge of the recess and the outline of the second base flap, there is no gap of sufficient size to allow the engagement of an object or a finger capable of lifting the second base flap away from the bell wall.

As regards the labeling means, it can advantageously be provided that they include:

- in each of said two second flaps, at least one latching light having an upper border,

- In the wall of the bell, at least one external latching protrusion shaped to engage, in the position of use, in said at least one latching light and to cooperate by latching with said upper edge.

Preferably, provision may be made for:

- in each of said two second flaps, there is provided a single latching light, having an upper border,

said upper edge is generally parallel to an extreme free edge of said second base flap and ends in two ends in a quarter of a circle,

- in the wall of the bell, with regard to each second flap of the base, there is provided a single external protruding ratchet shaped and positioned to engage in said latching light and to cooperate by latching with said upper edge,

- said external locking protrusion of the bell itself has a corresponding locking edge ending in two ends in a quarter of a circle.

In the presence of a single labeling lumen and a single external locking protrusion, handling of the packaging is facilitated for closing and opening with one hand.

72ï9FDEP.docx

It may be advantageous to provide that:

- said upper edge is curved with a convexity turned towards the inside of the snap-on lumen,

- said external protuberance for labeling the bell itself has a corresponding curved labeling edge,

- so that the labeling takes place essentially in the end zones of said upper border of the labeling light.

The curved shape of the protrusion and the upper ratchet light border promotes a resilient snap in the end regions of the upper ratchet light border, dividing the latching means into two distinct regions of the length packaging, and effectively opposing the risk of separation of the second flaps away from the bell wall.

According to a first embodiment, it is provided that:

- said two second flaps of the base have a height less than the height of the two opposite second sides of the bell,

- Said two second flaps of the base are detachably secured by said latching means to said two opposite second sides of the bell.

In this case, it may be advantageous to provide that:

- each latching light has, in the direction of elongation of its upper edge, a length between one third and half the length of the second base flap,

- each snap-in light has, in the direction perpendicular to the direction of elongation of its upper border, a height between half and two thirds of the height of the second base flap,

- each snap-in light is substantially centered in the second corresponding base flap.

A good compromise is thus achieved for effective snap-fastening and securing of the base and of the bell, in particular in the case of a cardboard base and of a thermoformed plastic bell. In addition, in the case of a bell made of transparent material, the labeling lights constitute windows through which the consumer can view an additional part of the product packaged in the packaging.

According to a second embodiment, it is provided that:

said two second flaps of the base have a height greater than the height of the two opposite second sides of the bell,

7219FDEP "docx

- Said two second flaps of the base are detachably secured by said latching means to said bell bottom.

This embodiment is particularly suitable for packaging relatively heavy products, because the securing of the second base flaps on the bell bottom is more resistant to oppose the mechanical constraints of spacing between the bell bottom and the base.

In all cases, it may be advantageous to provide that the first two base flaps have a height less than the height of the first bell sides, advantageously less than half the height of said first bell sides.

This arrangement is particularly advantageous in the case of a transparent plastic bell, leaving a better view of the product packaged inside the packaging, while guaranteeing a satisfactory connection between the bell and the base.

However, to increase the mechanical strength of the first base flaps, which ensure the stiffening of the base base during use, provision may be made to stiffen the first base flaps, for example an increase in the thickness of cardboard , or the fact that the first base flaps each have an end flap folded at 180 °.

In a first embodiment illustrated in Figures 1 to 8, the package 1 according to the invention comprises a base 2 and a bell 3.

As can be seen in FIG. 1, the base 2 is initially in the planar state, so that it is produced by simple cutting of a cardboard blank, and that it can be stored in this state until to be assembled with the bell 3. There is a base base 4, two first flaps 5 and 6, and two second flaps 7 and 8.

The base base 4 is rectangular in shape according to this embodiment, limited by two first fold lines 9 and 10 along two opposite small sides, and by two second fold lines 11 and 12 along two large opposite sides. The flaps 5, 6, 7, and 8 are each articulated on the base of the base 4 along a respective fold line 9, 10, 11 and 12 so as to be movable between a substantially planar storage position as illustrated in the FIG. 1, and a position of use, as illustrated in FIG. 8, in which the flaps 5, 6, 7 and 8 are substantially perpendicular to the base of the base 4.

The bell 3 according to this first embodiment is illustrated in FIGS. 2 to 6. There is a bell bottom 13 and a peripheral wall with four opposite sides two by two, respectively two small first sides 14 and 15 opposite one to the other. the other, and two large second sides 16 and 17 opposite each other.

The peripheral wall of the bell 3, constituted by the four sides 14, 15, 16 and 17, ends in a free edge 18 which is plane and has substantially the dimensions of the contour of the base base 4 so as to be able to rest on the base base 4, with the first fold lines 9 and 10 of the base base 4 internally bordering the free edge 18 of the bell 3, and with the second fold lines 11 and 12 of the base base 4 externally bordering the free edge 18 of the bell 3.

In the illustrated embodiment, the free edge 18 comprises a small peripheral sidewalk, which has no particular function in the packaging thus formed,

72l9FDEP, docx but which facilitates the cutting of the excess material during the production of a bell 3 made of thermoformed plastic. In other words, when using a bell 3 obtained by injection or other means, it is perfectly possible to produce a packaging according to the invention, the bell 3 of which has no sidewalk along its free edge 18.

The height H of the bell 3 is chosen so as to constitute an internal housing of sufficient volume to contain the products which it is desired to package in the packaging 1.

The first two sides 14 and 15 of the bell 3 have lower parts, respectively 14a and 15a, generally perpendicular to the plane of the free edge 18 or slightly convergent towards the bottom of the bell 13. The lower parts 14a and 15a extend from one side to the free edge 18 of the bell 3, and are connected on the other side to the bell bottom 13 by respective cylindrical parts 14b and 15b.

The two second sides 16 and 17 of the bell 3 are generally planar between their connections to the free edge 18 on the one hand and to the bottom of the bell 13 on the other hand, and are slightly convergent towards the bottom of the bell 13.

In their central part, the two second sides 16 and 17 of the bell 3 comprise an external latching protrusion, respectively 19 and 20. Each external latching protrusion such as the protrusion 19 has a latching edge 19a oriented towards the bell bottom 13. The latching edge 19a is generally parallel to the free edge 18 and ends in two rounded ends 19b and 19c in a quarter of a circle. The latching edge 19a is connected to the wall of the corresponding second side 16 by a latching groove 19d dimensioned so as to receive the thickness of the cardboard constituting the base 2.

In the illustrated embodiment, the snap-on edge 19a is also curved with a convexity facing the free edge 18.

The external snap projection 20 on the second side 17 of the bell 3 has the same shape as the external snap projection 19 described above, with a snap edge 20a, and with a snap groove 20d dimensioned to receive the thickness of the cardboard constituting the base 2.

Furthermore, still in this first embodiment as illustrated, each of the two second sides 16 and 17 of the bell 3 comprises a projecting peripheral rim, respectively 16a and 17a, so that the portion of the second sides 16 and 17 located between the peripheral edge 16a or 17a and

7219FDEP, docx the corresponding external snap-fit 19 or 20 forms a recess in which said two second flaps 7 and 8 of the base 2 will be housed in the assembled state of the packaging 1. For this, the peripheral flange 16a or 17a has a height at least equal to the thickness of the material constituting the base 2.

In other words, the recesses are limited by a peripheral rim 16a or 17a projecting, which peripheral rim has a height greater than or equal to a thickness of the second flap 7 or 8 of corresponding base.

We again consider the base 2 as illustrated in FIG. 1. Each of the two second flaps 7 and 8 comprises a snap-in slot, respectively 21 and 22, each having an upper edge 21a and 22a generally parallel to an extreme edge corresponding free 7a or 8a of the second corresponding flap 7 or 8, and each ending in two respective ends 21b and 21c for one, 22b and 22c for the other, each end being shaped as a quarter of a circle. The contour of each latching light 21 and 22 has the same shape as the contour of the external latching protrusion 19 or 20 of the bell 3, so that the external latching protrusion 19 can engage with latching into the latching light 21, and that the external latching protrusion 20 can engage with latching in the latching light 22.

In the variant illustrated in FIG. 1, the upper edges 21a and 22a are rectilinear, which may be suitable for snap-fastening on rectilinear snap-on edges 19a and 20a.

In the case where the labeling edge 19a or 20a is curved, the upper edge 21a or 22a is also curved, with the same convexity, as illustrated in FIGS. 6 to 8.

Furthermore, each of the two second flaps 7 and 8 is limited by an extreme free edge 7a or 8a dimensioned so that, when the second flap 7 or 8 is applied against a corresponding second side 16 or 17 of the bell 3, it comes fully engage in the recess of said second corresponding side 16 or 17 of the bell 3. In practice, said peripheral flange 16a or 17a follows at a slight distance the contour of the second flap 7 or 8 of corresponding base, said small gap being for example less than 2 mm.

In practice, in the first illustrated embodiment:

- each snap-in slot 21 or 22 has, in the direction of elongation of its upper edge 21a or 22a, a length between one third and half the length of the second flap 7 or 8 corresponding to the base,

7219FDEP.docx

- each snap-in slot 21 or 22 has, in the direction perpendicular to the direction of elongation of its upper edge 21a or 22a, a height between half and two thirds of the height of the second flap 7 or 8 corresponding to the base ,

- each snap-in light 21 or 22 is substantially centered in the second flap 7 or 8 corresponding to the base.

The strips of material of the base 2 located between the upper edge 21a or 22a and the free end edge 7a or 8a of each of the second flaps 7 or 8 in principle support the spacing forces between the bell 3 and the base 2 during the use of the packaging 1, under the effect of the mass of the products packaged in the packaging 1. To maximize the amount of material in this stressed area of the base 2, and thus to guarantee an effective connection between the base 2 and the bell 3, it is advantageously provided that each of the second flaps 7 and 8 has a dimension only slightly less than the dimension of the corresponding second side 16 or 17 of the bell 3.

In this case, as illustrated in this first embodiment of the invention, at its connection with the bell bottom 13 and with the first two sides 14 and 15 of the bell 3, each of the two second sides 16 and 17 of the bell 3 comprises a peripheral bead whose internal face constitutes the peripheral rim 16a or 17a projecting which ensures the protection of the latching means 19-22.

Each of the first two flaps 5 and 6 of the base 2 has, in the illustrated embodiment, a height less than the height of the two second flaps 7 and 8, and has a free edge 5a or 6a which may have a non-rectilinear profile, by example a concave profile. Furthermore, respective lateral edges 5b and 5c of the first flap 5 and respective lateral edges 6b and 6c of the second flap 6 are respectively set back from the second fold lines 11 or 12, as illustrated in FIG. 1.

The first flaps 5 and 6 in particular have a function of stiffening the base of the base 4, preventing its deformation downwards under the effect of a load constituted by products packaged in the packaging 1. It may then be advantageous to provide means for stiffening the first flaps 5 and 6 themselves, for example to provide that the first flaps 5 and 6 have a sufficient height to present an appropriate mechanical resistance. It can also be provided that the first flaps 5 and 6 each have an end flap folded at 180 °, possibly clipped or glued to the proximal part of said first flap, ensuring a doubling of thickness.

7219FDEP.docx

We now consider Figures 6 and 7 which illustrate the method of assembling the bell 3 on the base 2 for closing the packaging 1 of this first embodiment.

In FIG. 6, the two second flaps 7 and 8 are left to rest, the first two flaps 5 and 6 are raised in a direction substantially perpendicular to the base of the base 4 as illustrated by the arrows F1 and F2, and the bell is then approached 3 of the base 2 as illustrated by the arrow F3 by making the first two flaps 5 and 6 penetrate into the interior space of the bell 3.

Then, in FIG. 7, after having fully applied the bell 3 against the base base 4 along the free edge 18 of its peripheral wall, the two second flaps 7 and 8 are raised in a direction substantially perpendicular to the base base 4 as illustrated by arrows F4 and F5, until the two second flaps 7 and 8 are applied against the second sides 16 and 17 of the bell 3, making the upper edge 21a or 22a of their latching light 21 or 22 penetrate into the latching groove 19d or 20d of the external latching protrusions 19 or 20.

We now consider the packaging 1 in the position of use, that is to say fully assembled, as illustrated in Figure 8.

The bell 3 rests on the base of the base 4 along the free edge 18 of its peripheral wall.

The first two flaps 5 and 6 of the base 2 are engaged inside the bell 3, along the inner face of the first two sides 14 and 15 of the bell 3. The withdrawal of the side edges 5b, 5c, 6b and Respective 6c of the first flaps 5 and 6 is just sufficient to allow the penetration of the first two flaps 5 and 6 into the interior space of the bell 3. In this way, the lateral edges 5b, 5c, 6b and 6c constitute stops coming from bearing against the inner faces of the two second sides 16 and 17 of the bell 3 to oppose any relative translation of the bell 3 with respect to the base 2 in a direction parallel to the first two fold lines 9 and 10 Simultaneously, the first two flaps 5 and 6 oppose any relative translation of the bell 3 vis-à-vis the base 2 in a direction parallel to the two second fold lines 11 and 12, by their support against the inner face on the first two sides 14 and 15 of the bell 3.

The two second flaps 7 and 8 of the base 2 are arranged against the outer surface of the bell 3, and are secured to said outer surface in a detachable manner by latching means which are themselves protected against untimely detachment. In this case, in the first illustrated embodiment, the two second flaps 7 and 8 come to engage in the

72! 9FDEP.docx recesses made on the two second sides 16 and 17 of the bell 3 between the external locking protrusions 19 and 20 and the corresponding peripheral flanges 16a and 17a. Simultaneously, the two second flaps 7 and 8 snap into place, by engagement of the upper edge 21a or 22a of their snap-in lumen 21 or 22 in the snap-in groove 19d or 20d of the external snap-fit projections 19 or 20 The engagement of the second flaps 7 and 8 in the recesses of the two second sides 16 and 17 of the bell 3 allows the peripheral edges 16a or 17a to constitute a protective means which obscures the edges of said two second flaps 7 and 8, so as to make them inaccessible and thus avoid untimely detachment of the second flaps 7 and 8 away from the bell 3.

The base 2 can advantageously be made of cardboard, simply cut from a cardboard blank and compressed along the fold lines 9, 10, 11,

12. The bell 3 can advantageously be produced by thermoforming and cutting from a transparent plastic material. The product packaged in the package 1 thus formed is clearly visible to the user through the wall of the bell bottom 13, through the snap-in slots 21 and 22, and through the upper part of the first sides 14 and 15 of the bell 3, by the fact that the first flaps 5 and 6 occupy only part of the height of the bell 3.

The snap-fastening means 19 - 22, protected against their untimely detachment, ensure effective fastening of the bell 3 on the base 2, and thus make it possible to manipulate the packaging 1 by a grip pressing two opposite sides of the bell 3, preferably the two second sides 16 and 17 themselves covered by the second flaps 7 and 8.

A second embodiment of the invention is illustrated in FIGS. 9 to 12. This second embodiment differs slightly from the first embodiment, in that the snap-fastening ensuring the joining of the bell 3 on the base 2 s' performs on the upper face of the bell 3, that is to say on the outer face of the bell bottom 13, instead of being carried out on the lateral sides of the bell 3. Consequently, to avoid repetitions, the means which are identical in the second embodiment are identified by the same reference numerals as in the first embodiment, and their functions are identical.

We thus find, in this second embodiment, as illustrated in FIG. 9, a generally flat base 2 obtained by cutting a cardboard blank, with a base of the base 4, two first flaps 5 and 6, two second flaps 7 and 8 each having a respective latching light 21 or 22.

72i9FDEP, docx

We also find, as illustrated in FIG. 10, a bell 3 with a bell bottom 13, two first sides 14 and 15 opposite one another, two second sides 16 and 17 opposite one another .

In this second embodiment, the external latching protrusions 19 and 20 are produced in the bottom of the bell 13, and are each surrounded by a recess which extends both over a peripheral part of the wall constituting the bottom bell 13 and on an upper part of the wall constituting one and the other of the second sides 16 and 17 of the bell 3, as seen in Figure 10. The recess has a depth greater than or equal to the thickness of the blank of material constituting the base 2.

Note that, in this second embodiment, the snap edges 19a and 20a are, by way of example, curved with a convexity opposite to that of the first embodiment.

We now consider Figures 10 to 12 which illustrate the method of assembling the bell 3 on the base 2 for closing the package 1 of this second embodiment.

In FIG. 10, the two second flaps 7 and 8 are left to rest, the first two flaps 5 and 6 are raised in a direction substantially perpendicular to the base of the base 4 as illustrated by the arrow F1, and the bell 3 is then approached. base 2 as illustrated by arrow F3 by making the first two flaps 5 and 6 penetrate into the interior space of the bell 3.

Then, in FIG. 11, after having fully applied the bell 3 against the base base 4 along the free edge 18 of its peripheral wall, the two second flaps 7 and 8 are raised in a direction substantially perpendicular to the base base 4 as illustrated by arrows F4 and F5, until applying the proximal part of the two second flaps 7 and 8 against the second sides 16 and 17 of the bell 3, and until applying the distal part of the two second flaps 7 and 8 against the outer face of the bell bottom 13 by causing the upper edge 21a or 22a of their latching light 21 or 22 to penetrate into the latching groove 19d or 20d of the external latching protrusions 19 or 20.

FIG. 12 illustrates the packaging 1 of this second embodiment in the position of use, that is to say fully assembled.

As can be understood, the labeling means of this second embodiment are also protected against untimely stalling.

In addition, in this second embodiment, the labeling on the upper wall of the bell 3 is less stressed by the mechanical stresses produced by the weight of the products packaged in the packaging. This second

7219FDEPdocx embodiment is therefore suitable for supporting heavier loads than the first embodiment.

The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations thereof contained in the field of claims below.
