Description

The present invention relates to the field of packaging, in particular for presentation and sale, and relates to packaging intended for this purpose.

The invention also relates to a method for producing such packaging.

Currently, the presentation and sale of certain articles, in particular small articles, in particular jewelry, are generally carried out by means of rigid packaging, most often made of synthetic material.

These known packages certainly meet the requirements of users very satisfactorily, in particular as regards the enhancement of the products and their possible protection against shocks, but have the drawback of requiring a large space for their storage. .

In addition, these packages being intended for single use, there is the problem of their disposal, all the more difficult to solve since they are not biodegradable.

To overcome this drawback, multipurpose packaging boxes have been proposed, in particular in the form of a book with a rim. In such a case, the packaging box is made from a single piece and has two substantially identical parts, one of which forms the container and the other the cover, these parts being connected together by a back.

However, each part has only one front face and two lateral faces, the rear face being common and formed by the back. The box thus obtained is held closed by a blocking system consisting of a cooperation of at least one slot provided on the cover and at least one tab provided on the container.

In addition, such a box does not have a receptacle closed on four sides, for the reception of an article, nor an internal surface sufficient to receive a large inscription relating to said article. In addition, in such a form, the box has a very fragile back part to crushing. The addition of a receptacle could be envisaged in order to improve the presentation and the holding of the article in the packaging, however such an addition would entail a complication of manufacture and, as a corollary, a significant increase in production costs. .

The present invention aims to overcome these drawbacks.

Its purpose is, in fact, to present and sell packaging, in particular small articles, essentially constituted in the form of a book with a rim, produced from a single piece and having two parts, one of which forms the container and the other the cover, these parts being interconnected by a back, characterized in that the container has a receptacle with four side walls and in that the cover is provided with an internal part intended to receive a marking , the entire package being made from a blank single material cut and provided with fold lines printed by grooving.

The invention also relates to a process for producing such a package, characterized in that it essentially consists, firstly, of cutting by stamping from a sheet material a blank having all of the constituent parts of the packaging and to print, by simultaneous grooving between these parts, fold lines, then to carry out the volume setting of the packaging from the blank thus stamped and grooved by a first series of folding and gluing of the constituent parts of the receptacle and of the cover in order to obtain a flat packaging, and then to carry out a final volume setting by assembly without gluing of the entire packaging.

In accordance with the invention, and as shown more particularly in FIG. 1 of the accompanying drawings, the presentation and sales packaging, in particular of small articles, which essentially consists of a book with a rim, made from '' a single piece and having two parts, one of which forms the container 1 and the other the cover 2, these parts being connected together by a back 3, is characterized in that the container 1 comprises a receptacle 4 to four side walls and in that the cover 2 is provided with an internal part 5 intended to receive a marking, the entire packaging being produced from a single blank of cut material and provided with fold lines printed by grooving.

Such packaging is advantageously produced, as a first step, as shown in FIGS. 2 to 14, by cutting by stamping from a sheet material, a blank having all the constituent parts of the packaging, followed by the 'printing, by simultaneous grooving between these parts, of the fold lines, then of the packaging of the packaging from the blank thus stamped and grooved by a series of folding and gluing of the constituent parts of the receptacle and of the cover in order to obtain a flat packaging, and then of the final volume setting by assembly without gluing of the entire packaging.

For this purpose, the blank intended to form the packaging, obtained by cutting by stamping a sheet material, has, flat, a succession of individual surfaces of large dimensions 1, 2, 4 and 5 corresponding respectively, 1 and 4 to the container 1 and to the bottom of the receptacle 4, and 2 and 5 to the cover 2 and to its internal part 5, and interconnected. The surfaces 1 and 2 are connected by the back 3. The surfaces 1 and 4 are connected by two walls 6 and 7, with interposition between the surface 1 and the wall 6 of a longitudinal bonding strip 8 and, between the walls 6 and 7, a longitudinal separation strip 9. The surface 2 is connected to the surface 5 by two walls 11 and 12 with interposition between the surface 2 and the wall 11 of a longitudinal adhesive strip 10. The surface 4 is provided on the opposite side to walls 6 and 7 with walls 7 'and 6' connected together by a separation strip 9 ', the wall 7' being connected by its other edge to the surface 4 and the wall 6 'having on its other edge a bonding tab 22. The surfaces 1 and 2 are further provided, at their transverse ends, respectively, the surface 1 with external 13 and internal walls 14, the walls 13 being connected to the surface 1 by adhesive strips. 15 and to the walls 14 by separation strips 16, the walls 14 being provided s, on the side opposite to the strip 16, a locking tab 17, and the surface 2 of external walls 18 and internal walls 19 interconnected by their adjacent edges, the walls 18 being connected by their other edge to the surface 2 by means of an adhesive strip 20 and the walls 19 being provided externally with a locking tab 21, these various elements having at their junction with the adjacent elements of the fold lines.

The surfaces 1 and 2, as well as the back 3, have an identical length. The bonding strips 8 and 10 connecting respectively to the walls 6 and 11 have oblique ends. The sides in connection with said walls 6 and 11 are of length less than that of surfaces 1 and 2. The wall 12 connected to wall 11 is of a length slightly less than the latter and has at each end a slight offset relative to at the ends of the wall 11, while the surface 5 has a length identical to that of the wall 12.

The wall 7 has a length less than that of the wall 6, and the separation strip 9, which protrudes on either side the ends of the wall 7, has at its ends projecting elements 23 which, at the level of the junction with the wall 7, are extended by a notch 23 ′ penetrating into the strip 9 (Figures 2 and 4 detail C).

The wall 7 ′, which is connected to the wall 6 ′ by a strip 9 ′, has a length greater than said wall 6 ′ and the strip 9 ′ is identical to the strip 9. The adhesive tab 22 has a length considerably shorter to that of the wall 6 ′ and corresponding to the length of the surface 4, which is provided at its ends with two transverse cuts 24.

The walls 13 are connected to each end of the surface 1 by means of the adhesive strips 15, one end of which is in alignment with the first fold line of the back 3, while the other end extends obliquely in alignment with the ends of the adhesive strip 8. The corresponding end of the wall 13 extends in the longitudinal direction of the surface 1, while its opposite end has a rounded radius of substantially equal to that of the back 3 The wall 14 and the locking tab 17 are of equal length, but less than that of the wall 13 to which the wall 14 is connected by the strip 16 whose ends are oblique.

At the connection between the separation strip 16 and the wall 14, there is provided, at each end of the fold line, a notch 25 intended to cooperate with the projecting elements 23 of the strips 9 and 9 '(detail B , Figures 2 and 4).

In addition, the walls 6 and 7 'are provided at their ends with flaps 26 intended to cooperate with the walls 13 and the separation strips 16, in the packaging mounting position, the locking tabs 17 then pressing against the cutouts 24.

Each wall 18 is connected to one end of the surface 2 by a strip 20 similar to the strip 15 for connecting the wall 13 and has, on its side facing the back 3, a rounded radius corresponding to that of said back 3 and , at its opposite end, a hook-shaped part 27 connected by its beak to that of a corresponding hook-shaped part 27 secured to the corresponding end of the wall 19, the other end of which also has a rounded shape. The hook-shaped part 27, fixed to the wall 19, is cut at this junction, this cut 27 '' encroaching on the wall 19 and creating an edge in the latter, which, in the service position, cooperates with a slight projection 27 'from the ends of the wall 12. The locking tabs 21 extend, in the operating position, under the surface 5 forming the internal part of the cover 2 (detail A, FIGS. 2 and 3).

According to an alternative embodiment of the invention, the walls 18 and 19 are provided, in place of the parts 27, each with a tongue, the said tongues being connected together at the junction between the walls.

The packaging of the packaging according to the invention, from the aforementioned stamped blank, is advantageously carried out in two main stages, namely a stage of folding and gluing and a stage of assembly.

Folding and gluing can be carried out, in a known manner, in two successive passes in a machine folder-gluer, a first pass being made in the longitudinal direction, as shown more particularly in Figures 5 to 8, in order to fold and glue the strips 20 and the walls 18 and 19, as well as the gluing of the strips 15. The FIGS. 6 to 8 show more particularly the sequence of operations carried out for folding and gluing the strips 20 and the walls 18 and 19.

A second passage is then carried out in a transverse direction, as shown in FIGS. 9 to 12, in order to fold and glue the strip 10 and the longitudinal edges of the receptacle 4 by gluing, first of all the strip 9, followed a folding, towards the side opposite the back 3, of the wall 6 at its junction with the strip 8, then a folding of the surface 4 along the edge of the wall 7 and a bonding of said surface 4 on surface 1, another folding then being carried out between the wall 7 ′ and the strip 9 ′ followed by gluing of the strip 22 inside the surface 4. These various operations are shown in the figures 10 to 12.

A package is thus obtained in the form of a flat box which can be set in volume by simple assembly, without gluing, either manually or by means of a machine. This assembly is carried out in two stages, according to an indifferent order.

The receptacle 4 is produced by straightening the rear walls 6 ′, 7 ′ and the front walls 6, 7, then folding inwards the flaps 26 of the walls 6 and 7 ′. The side walls 13, 14 are then put in place in order to ensure the maintenance of the walls 6 ', 7' and 6, 7 by cooperation with the flaps 26 against which the walls 13 come to lock, the strips 16 being pressed against the upper edges of bands 9 and 9 '. The walls 14 are folded down to form the internal structure of the side walls, then are kept locked in a position parallel to the walls 13, by the locking tabs 17, which abut in the cutouts 24 of the surface 4 forming the bottom of the receptacle 4 (Figures 13 and 14).

The mounting of the cover 2 (FIG. 13) is carried out by a first folding of the hook-shaped parts 27 of 90 ° inwards, then by straightening of the wall assemblies 18, 19. Then, the wall 11 is straightened and the wall 12 is folded inwards with pressing against the wall 11 and imprisonment of the hooks 27, in order to keep the walls 18, 19 in a vertical position.

To allow a blocking in position of the wall 12, and thus of the surface 5, the latter is provided on its two lateral edges with a blocking slot 28 intended to cooperate with the corresponding edges of the blocking tabs 21. Thus, by folding of the surface 5 against the internal face of the surface 2, the wall 12 is held against the wall 11 and the surface 5 remains pressed against the surface 2.

This support is reinforced by the locking of the projections 27 ', provided at the ends of the wall 12, against the cutout 27' '.

The assembly is then completed and the packaging can be closed by folding the cover 2 over the receptacle 4. For this purpose, the back 3, which is advantageously provided with multiple grooving, allows easy closing of the packaging. Maintaining the cover 2 on the receptacle 4 is obtained, in known manner, by means of a locking tab 29 provided in the wall 12 and cooperating with one or more slots provided in the wall 6. Such an embodiment allows repeated openings and closings.

The packaging according to the invention is described in connection with a box having a rounded connecting back between the receptacle 4 and the cover 2. However, the latter may also have another shape, the lateral parts of the walls then having a corresponding shape and the multiple grooving then being limited to the grooving necessary for the other shape.

According to another characteristic of the invention, and as shown in FIG. 17 of the accompanying drawings, the receptacle 4 may be provided with a sheet 31 of rolled paper, fabric or the like, intended to receive an impression, such as a brand or whatever. Such a sheet 31 improves the interior aesthetics of the packaging, for example to form a case.

According to another characteristic of the invention, the internal part 5 of the cover 2 is advantageously connected to the wall 12 in a detachable manner, the fold line between the wall 12 and the internal part 5 being in the form of a tear-off strip. Thus, part 5 can be, for example, in the form of a detachable card receiving an entry, namely, for example, in the form of a guarantee voucher.

Figures 15, 16 and 18 show an alternative embodiment of the invention, in which the receptacle 4 is provided with an adapter 32 in the form of an inverted tank constituted by a stamped flat part provided with four foldable edges, this part can be provided in its central surface with two stamped holes 33 connected to each other by a slot of rounded shape 34 and in which can be placed an elastic or non-elastic holding device 35. Such an adapter 32 is more particularly intended to be applied by light pressure in the bottom of a package, in order to receive a small, slender or other object.

Thanks to the invention, it is possible to produce a packaging having a receptacle 4 with four side walls, as well as, in the cover 2, a surface intended to receive a marking or a printing. The four walls of the receptacle 4 make it possible to avoid the fragility of the dorsal part and to improve the aesthetics of the packaging, while the internal part 5 makes it possible to significantly improve the aesthetics of the interior of the cover 2, by masking the blocking structures of the lateral faces, as well as the internal face of the cover.

Such packaging can be made of any flexible and pliable material, namely cardboard or synthetic or other material.

Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
