Abstract

The box has side walls (11) and bottom (12) together form body of the box. Sides of a triangular shaped end wall (31) are articulated on one of the side walls. A base of the end wall is prolonged towards interior of the box by a shutter (50) to slide the end wall against the base of the box. The end wall and the shutter occupy closed position in which the end wall closes an opening (16) and opened position in which the end wall defines a distribution zone to distribute products appearing in the opening, where the box is realized by cardboard blank or analogue.

Description

The invention relates to a box for the packaging and dispensing of products, made by folding a sheet material. This box is designed for products packaged in portions. It is more particularly intended for the packaging of triangular portions, for example portions of cheese having a rounded shape, such as pie charts. This box thus has two side walls and a bottom, so as to define a triangular section of cavity capable of accommodating these portions of cheese. Such a box is already known in the form of a box of triangular section for food products. The opening of such a box is achieved through a tear-off tongue that allows to completely free one of its end walls and without the possibility of closing the box. This box is not suitable for packaging portioned products. Indeed, these products are not intended to be all consumed at the same time. It is therefore appropriate to be able to close the box between two product distributions. In addition, when the opening is released, the distribution of a product causes that of all the products, because of their weight. This makes the package inconvenient for a user. The invention therefore aims to overcome these disadvantages by providing a box for packaging and dispensing products, in particular packaged products in the form of portions, made by folding a sheet material, this box comprising a first and a second side wall and a bottom, forming the body of the box, as well as two walls

end of triangular shape, one of which closes an opening of said box. According to the invention, one of the sides of said end wall is hinged to the second side wall and the base of this same end wall is extended towards the inside of the box by a sliding flap. against the bottom of the box, said end wall and the flap being capable of occupying a first closed position, in which said end wall closes said opening and a second open position, in which they define a distribution zone and presenting products appearing in said opening. Thus, this box makes it possible to close the opening intended for the distribution of the products, between two uses. In addition, the articulated end wall and the flap form a slightly narrowed passage that allows the dispensing of products one by one.

Finally, in the open position, the flap extends the bottom of the box and constitutes a plateau for the product. This facilitates the taking of the product by the user. Preferably, in the second side wall, the box comprises a precut line defining a tab integral with said articulated end wall. The presence of this precut line facilitates, for the user, the separation between the articulated end wall and the second side wall, in order to release the opening of the box. Advantageously, the box comprises means for limiting the rotational movement of said articulated end wall and its flap. The presence of these means keeps the flap in the extension of the bottom of the box. The shutter thus retains its display function, when the opening of the box is released. These limiting means may for example consist of a lug projecting from the flap and a notch located on the second wall.

lateral, this pin being engageable in said notch, in the open position of the box. Preferably, the first side wall is extended by a flap which is supported on the bottom of the box, said flap and said bottom defining a double-walled area in which said flap is pivotable. This double-walled zone keeps the flap against the bottom of the box, both in the closed position and in the open position. The box according to the invention advantageously comprises a repositionable fixing lug which is fixed on the pre-cut tongue provided in the second side wall. This bracket makes it easier to open the box and secure its closure, once the tab cut. This fixing lug advantageously consists of two superimposed films, the lug having an adhesive layer over the entire face intended to be opposite the second side wall, with the exception of a central zone. The presence of this central area facilitates tearing of the tongue, when the user pulls on the bracket.

Finally, the free end of the bracket is advantageously free of any adhesive to facilitate its handling by a user. The invention also relates to a cardboard blank or the like for producing a box according to the invention.

This blank comprises: three panels articulated together by a first and a second fold line, for the formation of the body of the box, with successively a first and a second side panel and a panel corresponding to the bottom of said body, means for fixing the bottom panel and the first side panel together, and

two triangular portions connected to the second side panel, by a third, respectively a fourth fold line corresponding to one of their sides, for the formation of the end walls, the base of one of the triangular portions extending by a flap independent of said panels. According to one embodiment, said fixing means comprise a flap connected by a sixth fold line to the longitudinal edge of the first side panel. These fixing means may also comprise at least one tab provided on the longitudinal edge of the bottom panel, and at least one notch provided on said sixth fold line, said at least one tab being adapted to fit into said at least one fold line. a notch. In a preferred manner, the two triangular portions extend, at the level of the other of their sides, by a flap.

Finally, the blank advantageously comprises a precut line in the second side panel, whose two ends are located on said fourth fold line. The invention will be better understood and other objects, advantages and characteristics thereof will appear more clearly on reading the description which follows and which is made with reference to the accompanying drawings in which: Figure 1 shows a blank from which, after folding and gluing, is obtained a box according to the invention, Figure 2 is a detail of Figure 1, illustrating a repositionable fastening tab, in position on the blank of Figure 1 - Figure 3 is a view in plan of said repositionable tab illustrating its different functional zones, FIGS. 4 and 5 illustrate two successive stages of folding of the blank illustrated in FIG. 1, to obtain a box according to the invention, FIG. in perspective of the box according to the invention, obtained from the blank shown in FIG. 1, the box being in the closed position and

Figure 7 is a view similar to Figure 6, the box being in the open position. The elements common to the different figures will be designated by the same references.

The blank shown in Figure 1 comprises three panels: two side panels 10 and 11 and a panel 12 which will form the bottom of the body of the box. These panels are interconnected by fold lines. The blank is illustrated on the outside, that is to say on the side that will be visible from the outside, after folding to form a box. Thus, a first fold line 20 is provided between the first and second side panels 10 and 11 and a second fold line 21 is provided between the second side panel 11 and the bottom panel 12. The first and second side panels 10 and 11 are identical.

These two fold lines 20 and 21 are substantially parallel to each other. As will be illustrated in Figures 4 to 6, they allow the articulation of the three panels together. The blank also has two triangular portions 30 and 31, each connected by one of their sides to the second side panel 11.

Thus, the first triangular portion 30 is connected to the side panel 11 by the third fold line 22 and the second triangular portion 31 is connected to the side panel 11 by the fourth fold line 23. Each fold line 22, 23 corresponds to a side of each triangular portion 30, 31.

A notch 210 is provided on the second fold line 21, near the fourth fold line 23. These two triangular portions 30 and 31 will allow the formation of the end walls of the box obtained from this blank. The other side of the two triangular parts is extended by a flap.

Thus, the first triangular portion 30 is connected to a flap 40 by the fold line 32. Similarly, the second triangular portion 31 is connected to a flap 41 by a fold line 33. Each fold line 32, 33 corresponds to the other side of each triangular portion 30, 31.

FIG. 1 also illustrates a layer of glue 42, 43 deposited on the outer face of each flap 40, 41. The second triangular portion 31 is extended, at its base, by a flap 50. Thus, the second triangular portion 31 is connected to this flap 50 by the fold line 34, corresponding to the base of the second portion 31. As illustrated in FIG. 1, this flap 50 is connected only to the second triangular portion and it is independent of the three panels 10 to 12. This flap 50 has the shape of a circular sector. One of the right sides of this sector corresponds to the fold line 34. The other right side is 51. The angle formed between the two right sides 34 and 51 is about 90 degrees. In general, this angle is between 60 and 90 degrees. Finally, the flap 50 has a rounded edge 52. Close to the right side 51, the rounded edge 52 has a lug 520 projecting from the rounded edge 52. A fold line 35, passing through the height of the second part triangular 31, is provided both on the second triangular portion and on the flap 50. The first triangular portion 30 is also extended, at its base side, by a flap 60 which is also connected to the second bottom panel 12. In other embodiments, this flap 60 could be omitted.

In the example illustrated in Figure 1, the flap 60 is composed of two parts 61 and 62 separated by a fold line 38 which starts from the second fold line 21. Thus, the first triangular portion 30 is connected to the first part 61 of the flap 60 by the fold line 36, corresponding to the base of the first part. Furthermore, the second portion 62 of the same flap 60 is connected to the side panel 12 by a fifth fold line 24. As for the flap 50, another fold line 37, passing through the height of the first triangular portion 30, is provided on both the first triangular portion and the flap 60. The first side panel 10 is extended, on the opposite side to the first fold line 20, by a flap 13. Thus, the first side panel is connected to it. flap 13 via a sixth fold line 25.

In this fold line 25 are made two notches 250 and 251. The bottom panel 12 is extended, on the opposite side to the second fold line 21, by two tabs 14 and 15. Thus, the bottom panel 12 is connected to the tab 14 by a seventh fold line 26 and the tab 15 by an eighth fold line 27. In the second side panel 11 is provided a precut line 100 whose two ends 101 and 102 are on the fourth line 23. This precut line 100 defines a tongue 17. In a conventional manner, this blank is obtained by cutting a sheet material made of cardboard or a similar material. The fold lines are obtained by crushing, thanks to appropriate tools. In addition, the notches, like the precut line, are obtained by cutting tools.

Referring now to Figures 4 and 5 which illustrate two folding steps to obtain a box, from the blank shown in Figure 1. In Figure 4, it is the inner face of the blank which is visible, unlike Figure 1 which illustrates the outer face of the blank. The first side panel 10 and the bottom panel 12 are slightly bent with respect to the second side panel 11, around the fold lines 20 and 21. Similarly, the flap 13 is folded around the sixth fold line 25 and the two tabs 14 and 15 are folded around the seventh and eighth fold lines 26 and 27. The first triangular portion 30 is folded inwardly around the third fold line 22. Similarly, the flap 40 is folded inwardly around the fold line 32.

The flap 60 is folded around the fold line 38, which advances towards the inside of the blank by separating the two parts 61 and 62 of this flap. It is also folded inwards around the fold lines 24 and 36. The second triangular portion 31 is also folded inwardly around the fourth fold line 23, like the flap 41 around the fold line 33. Finally, the flap 50 is also folded inwards around the fold line 34. In the position illustrated in FIG. 5, the two triangular portions 30 and 31 are folded substantially at 90 degrees with respect to the second lateral panel 11. Furthermore, the two flaps 40 and 41 are slid under the first side panel 10, which will subsequently ensure the bonding of these flaps on the side panel. In the example illustrated in the figures, this bonding is obtained 30 thanks to the adhesive layer 42, 43 deposited on each flap and which comes into contact with the internal face of the side panel 10.

Finally, the flap 13 is slid under the two flaps 50 and 60. Before closing the box, it is filled with products, for example triangular portions of cheese, individually wrapped. The closure of the box is carried out by raising the bottom panel 12 against the flap 13 and inserting the lugs 14, respectively 15 in the notches 250, respectively 251. The result is the triangular section box illustrated in FIG. is in closed position. In this perspective view, are visible a side wall corresponding to the second side panel 11 of the blank shown in Figure 1 and an end wall corresponding to the second triangular portion 31 of the blank. The edges of the box illustrated in FIG. 6 correspond to fold lines of the blank of FIG.

Thus, the upper edge between the two side walls 11 and 10 of the box corresponds to the fold line 20. The edge between the second side wall 11 and the end wall not visible in Figure 6 corresponds to line The edge between the second side wall 11 and the bottom of the box corresponds to the fold line 21.

Similarly, the edges between the end wall 31 and the first side wall, the second side wall and the bottom correspond to the fold lines respectively 33, 23 and 34. These edges also correspond to both sides and to the base of the end wall. On the outer face of the second side wall 11 appears a repositionable fastening tab 70 which will now be described in more detail with reference to Figures 2 and 3. Figure 2 is a detail of Figure 1 showing how the bracket is placed on the blank. In practice, this tab 70 is placed on the blank after it has been completely completed, that is to say after the steps of cutting, pre-cutting and forming the fold lines.

Thus, this tab is positioned on the outer face of the second side panel 11, so as to cover substantially all the tongue 17, defined by the precut line 100. In the example shown in Figure 2, the base 72 of the tongue 70 overflows even slightly on the second triangular portion 31, beyond the fold line 23. In an exemplary embodiment, this tongue 70 is composed of two superimposed films and connected by an adhesive layer. Figure 3 illustrates the tab seen from the side of the lower film, that is to say the one that will come into contact with the blank.

On this lower film are provided three transverse precut lines. The first 73, sawtooth, is located near the free end 71 of the tongue, and the second and third precut lines 74 and 75 are located in the central zone of the tongue. These lines delimit four different zones on the tongue 70. In the first zone 76, located between the free end 71 of the tongue and the first precut line 73, the lower film has no adhesive. Between the first and second precut lines 73 and 74 delimiting the zone 77, the lower film is provided with an adhesive. It is devoid of it in the zone 78 defined between the second and third precut lines 74 and 75 and it again comprises an adhesive in the zone 79 defined between the precut line 75 and the base 72 of the tongue. Thus, thanks to the adhesive present on the zones 77 and 79, the tongue 70 can be fixed on the blank, as illustrated in FIG. 2. When the user wishes to open the packaging, he grasps between his fingers the zone 76 and pull the tab backwards. Thanks to the precut lines 73 and 74, the lower film remains stuck on the side wall 11. Because of the absence of bonding on the area 78, the two films then remain secured. They are also secured to the side wall 11 at the pre-cut tongue 17.

Thus, the lifting of the tongue 70 causes the detachment of the tongue 17 of the side wall 11, the precut tab 17 and the repositionable tab 70 being integral. In addition, the lifting of the tongue causes the opening of the end wall 31 which is then in the position shown in Figure 7. Figure 7 shows the box of Figure 6, in the open position. On the lateral face 11, appears a portion of the lower film of the tongue 70, referenced 77a, which remained stuck on the box, after the lifting of the tongue 70. This part 77a will allow the repositioning of the tongue, when the user wish to close the box. FIG. 7 also shows the pre-cut line 100 made in the side wall 11.

Upon opening, the end wall 31 has pivoted about the fold line or its side 33, towards the outside of the box. This rotational movement caused the flap 50. During this movement, the flap 50 slid against the bottom 12 of the box. Near the first side wall 10, the flap 50 has slid between the bottom 12 of the box and the flap 13. In fact, near the first side wall, the bottom 12 and the flap 13 form a double-walled zone guiding the shutter when it slides against the bottom of the box. In the position illustrated in Figure 7, the lug 520 provided on the flap 50 is inserted into the notch 210 provided on the second fold line 21. The cooperation of the lug 520 and the notch 210 can limit the opening movement of the end wall 31 and the flap 50. Thus, the flap 50 remains in the extension of the bottom 12, when the box is in the open position. The shutter thus acts as a tray or display for the products passing through the opening 16 released by the end wall 31.

Moreover, the angle formed between the end wall 31 and the flap 50 is less than 90 degrees and generally between 40 and 90 degrees. This makes it possible to slow down the passage of the products coming from the inside of the box and thus to prevent it from being emptied completely when the user shakes it slightly to release a product. With the repositionable tab 70, the user can effectively close the box between two product distributions. The numerical references inserted after the technical characteristics appearing in the claims are only intended to facilitate understanding of the latter and can not limit its scope.15
