Description

"Flan and procéc to form a folding box of packaging, box as well

  The present invention relates to a packaging box which can be formed by folding a blank, in particular a blank made of cardboard, The present invention also relates to a method for forming the box from the blank.

  For wrapping clothes, especially shirts, parallelepipedic boxes known as pastry boxes are generally used in two parts, one containing and the other forming a lid. The contents of the container can be discovered by lifting the lid. These boxes can be equipped with a window to observe their contents and are formed by folding a cardboard blank. The shaping of such a box from the side is difficult. In addition, some parts of the blank must necessarily be glued together before formatting.

  Other boxes, called cushion boxes are used, generally for wrapping small clothes or accessories. These boxes are easily formed by folding a carton blank. They have two first faces (convex ends, each convex face having two opposite sides rectilign! S and two curved sides, and two other opposite faces in the form of concave cruisers, serving for the introduction of the content and maintenance forrr 3 of these boxes also require a gluing of the first two aces between them, prior to shaping In addition, contrary to the pastry boxes, they do not allow to discover the cont mu without removing it, and Therefore, because of their curved shape, such boxes, once shaped, are difficult to arrange.

  An object of the invention is to provide a blank which allows to easily make a b) by folding of this blank, possibly without gluing or assembly near table, the box thus produced to enhance the product -2 - According to a In the first embodiment of the invention, a blank for forming a collapsible box comprises a central band and at least one lateral band connected to the central band by a respective inner lateral fold, the central band comprising several central panels, preferably quadrangular ones. at least a bottom and a first flap, the bottom being connected to the first flap by an inner transverse fold and the respective lateral fold to a side panel respectively formed in each side strip, the first flap is connected by the side fold respective to a first flap, a margin being formed in the lateral strip, the margin being connected to the side panel 31 by a first margin fold, interior and at the first flap by a second fold of margin, outside, the second fold of margin and the lateral fold resp ective, in its part separating the first flap and the first flap, forming an acute angle for this first flap.

  In addition, in the central panels, the blank may comprise a back connected to the bottom by another inner transverse fold and the respective lateral fold on one side formed respectively in said each lateral band, each hinge comprising a back portion and a lateral part, the dorsal part being connected to the back by the respective lateral fold, the lateral part being connected to the side panel by a first inner hinge fold, the first hinge fold extending the other transverse fold, the two parts being connected by a second hinge fold, exterior and concurrent with the side fold and the first hinge fold at a hinge point.

  The blank may also include a second flap connected to the back by a third tran, versai, interior.

  The one or more v) lets form an openable side of the box. Thus, the blank may comprise means for attaching a flap to one of the other center panels, for example by means of a lace, to secure the closure.

  Advantageously, the blank may comprise two sidebands, the central band being disposed between the two sidebands. The sidebands thus make it possible to form two sides of the box, each with a specific side panel, two other sides being formed by the back and the bottom.

  The blank may further comprise a second flap formed in the lateral band, the second flap being connected to the second flap by the respective lateral fold E: at the dorsal portion of the hinge by a third external hinge fold, the third hinge fold extending the third transverse fold. This ri beats to keep the back of the hinge against the bottom.

  The transverse folds may be parallel to each other. The back and the bottom may be rectangular, the lateral fold then being perpendicular to the trans-folds.

  According to a second object of the invention, a box comprises such a blank.

  According to a third object of the invention, a method for forming such a box is coded in that, in accordance with the respective lateral fold, each band erases it against the central band, and then the back is relatively straight. in ond, possibly together with the second component if one exists, while maintaining the back portion substantially vis-à-vis with the ios, until it is substantially vis-à-vis -vis with the side part.

  According to a qt. Third object of the invention, a method for forming such a box is that it is actérisé in that one folds, according to the respective lateral fold, each band lai arale against the central band, then in that one folds the first flap reliently at the bottom, holding the first flap against the first flap until the first flap is substantially in contact with the nge the side part.

  Especially when there is a second flap, its presence is sufficient to maintain the back and dorsal bet vis-à-vis with the back. The dorsal part can be held opposite to the back by mutual bonding. In this case, the blank can be delivered to a user with the sidebands folded over the central band (the blank however remaining substantially flat and, therefore, little encomb.ant.

  The blank is generally made from a sheet of foldable material sufficiently rigid. An outer surface of the fire is then called an island for forming the outside of the box. The outer surface is generally printed or decorated. The opposite surface of the leaf is inside. By assimilation, we call inner fold a preformed fold q Ji tends to fold the inner surface on itself, and outer fold a fold reformed which tends to fold the outer surface on itself.

  Other features and advantages of the invention will emerge from the description below, relating to non-limiting examples. In the accompanying drawings: FIG. 1 is a perspective view of a blank according to the invention, in a first embodiment, partially in the form of a box according to the invention; - Figure 2 is a perspective view of the box of Figure 1, shaping and ouve te; FIG. 3 is a perspective view of the box of FIG. 1, shaped and closed; - Figure 4 is a left half view, in plan, of a blank to form the box of figt. -e 1; - The figure is a half right view, in plan, of a second embodiment pop r a blank according to the invention.

  FIG. 6 is a perspective view of a third embodiment for the blank according to the invention; - the figures. 7 and 8 are perspective views of two steps for shaping a box from the blank of Figure 6; and FIG. 3 is a perspective view of the box formed from the blank of the figure, closed.

  We will abc -d describe a first embodiment for the invention, with reference to Figures 1 to 4.

  FIG. 1 depicts a box 1 being shaped from a blank 2 as illustrated in FIG. 4. The blank is rectangular and symmetrically related to a longitudinal line of symmetry S. In figure -5 - 4, only half of the blank on the left of this line S, which is drawn in phantom, is shown.

  Such a blank o prints several separate panels and connected by preformed folds. These are generally represented by dashed lines, or by solid lines when they are sufficiently marked. The panels form a central strip 10 and two side strips 20. The side strips are arranged on either side of the central strip and each latéral strip is separated from the central strip by a respective lateral fold 30 -their. The lateral folds are substantially parallel to the line of symmetry. S. The lateral and central bands are of the same length, measured? parallel to the line of symmetry.

  The panels K of the central strip 10 are: a bottom 11, a back 12, and two flaps 13 14. The panels of the central strip are all rectangular and the transverse dimension L10 identical, that is to say that the width L10 of the central band, measured perpendicular to the line of symmetry S, e; t substantially constant. The bottom 11 and the back 12 are connected by a first inner transverse fold 31. The bottom and a first flap 13 of IE 3 two flaps are connected by a second transverse fold 32, inside. The los 12 is connected to the second flap 14 by a third transverse fold 33, inside. The transverse folds are substantially perpendicular to the lateral folds.

  For each sideband, the panels are: a back portion 21 and a side portion 22 of a hinge 21,22, a side panel 23, a margin 24, a first flap 25 and a second flap 26. The width L20 of each linear band, measured perpendicular to the line of symmetry S, is substantially constant. Subsequently, the description is made for a single IE teral band; it applies to both sidebands, symmetrically.

  The back 12 E is connected by the lateral fold 30 to the dorsal portion 21. The bottom is connected by the side p i to the side panel 23. The side panel 23 is itself connected p; r a first hinge fold 41, inside, to the side portion 22 of hinge 21,22. The two parts are interconnected by a second fold and hinge 42. This second hinge fold 42 is an outer fold. The second eleventh flap 14 is connected to the second flap by the lateral fold. The second flap is connected to the dorsal portion 21 of the hinge by a third hinge 43.

  When the f 3n is flat, as shown in Figure 4, the first hinge ply prol, nge the first transverse fold, in the same alignment as it, and the third hinge fold extends the third transverse fold, in the same alignment as the latter. Thus, the first and third 3-hinge folds are perpendicular to the side fold.

  In addition, the distance between the first and third folds of the hinge, ie the longitudinal dimension L12 of the back, is equal to the width L20 of the sideband. So, the hinge is a square. In addition, the second crease 42 extends along a diagonal of this squaring square with the first transverse fold 31 and the lateral fold 30. The two parts of the third are therefore isosceles right triangles of identical dimensions.

  The side panel 23 has the shape of a triangle whose first side is formed by the lateral Dli 30 which connects it to the back, a second side by the first ply 41 which connects it to the side portion 22, and whose third side is formed by a first margin fold 44, interior, which connects the side panel 23 to the margin 24.

  The first olet 13 is connected to the first flap 25 by the side fold 30. The first flap is connected to the margin 24 by a second margin fold 45, outside. The Steri fold 30, the second transverse fold 32, the first margin fold 44 and the second diagonal fold 45 are concurrent.

  The side panel 23 is a right triangle. The first margin fold 44 is shown along the hypotenuse of this rectangle. The margin 24 is also a triangle formed by the first margin fold 44 and whose two other sides are respectively formed by the second margin folds and an outer edge of the blank 2.

  The second fold of margin extends the second transverse fold 32, but these two ps are not in the same alignment, when the blank 2 is flat, in a position of Figure 4. They are arranged so that the second fold margin 45 and the lateral fold 30, in its part separating the first flap 13 and the first flap 25, form an acute angle for this first flap 25; the first flap is therefore trapezoidal, its opposite side to the lateral fold 30 E being smaller than that formed by the lateral fold 30. In the example illustrated, the margin forms a substantially isosceles triangle whose base is the second: fold of margin 45 and whose other two sides are substantially of the same dimension. In this configuration, the box being shaped, Il side panel 23 is substantially perpendicular to the bottom 11.

  We will now describe a second embodiment for a blank according to the invention, with reference to Figure 5, only in that it differs from the embodiment of Figures 1 to 4. As the blank shown in FIG. 4, the blank 32 of FIG. 5 is symmetrical relative to a line of symmetry S lor itudinale, which is drawn in phantom.

  The horizontal band 20 of the blank 102 has a first width L20, constant at the level of the hinge 21,22 and the second flap 26, and a second width L120, constant at the side panel 23, the margin 24 and the first flap 25. The side panel is triangular and inscribed in the first width L20, so that the margin is trapezoidal and fits in the second width L120.

  In this embodiment, although the margin extends beyond, it also includes a substantially isosceles triangle whose base is the second narge fold (45) and one of the other two sides is the first margin fold ( 44), thus making it possible to straighten and maintain the side panel perpendicular to the bottom.

  Furthermore, in this embodiment, apertures 4 are cut in the blank at the two points where the side fold 30 and, respectively, the first transverse fold 31 and the second transverse fold 32 intersect. cuts 4 allow easier formation of the folds, especially if the blank is made in a thick sheet. This therefore makes it easier to fit the box and prevents it from becoming unfolded under the elastic action of the sheet material to the right of these points. -8 -

  In the embodiment of FIGS. 6 to 9, which will be described in that it differs from the embodiment of FIGS. 1 to 3, the blank 202 comprises a jig 50 extending longitudinally from a transverse free edge 50 of FIG. first flap 13. The tongue 50 is formed of three tab panels 51-53. A first tongue panel 51 is connected to the first flap 13 by a first tongue fold 61, transverse and inner. A second tongue panel 52 is connected to the first tongue panel 51 by a second tongue fold 62, transverse and inner. The second tongue panel 53 is connected to the second panel 52 of the nguette by a third tongue fold 63, transverse and inner. The tongue panels are of small longitudinal dimensions. The transverse width L 50 of the tongue is chosen narrower than the width L.sub.10 of the central strip, so that when the first flap is. folded against the margins, the tongue can fit between the margins without being embarrassed.

  The first flap 13 and the second tongue panel 52, each have an orifice 54, arranged so that when the tongue is foldably folded on itself around the tongue folds 61-63, the two orifices 54 are substantially vis-à-vis one another.

  The blank 202: further includes a slot 55 extending from a free transverse edge 56 of the second flap 13 to another orifice 57. This other orifice 57 is arranged so that when the flaps are folded one on the other. other, this other orifice is substantially vis-à-vis with the orifices 54.

  We will now describe a method for forming a box from blank 2,102,202 among those previously described.

  To form the box 1, the blank 2 is first folded along the lateral fold 30, so that the inner surfaces of the lateral strips 20 substantially come into contact with the inner surface of the central strip 10.

  Next, the back 11 is raised relative to the bottom, 12 around the first tram / ersal fold 31, as illustrated in FIGS. 1 and 8. The first transverse fold and the second hinge fold are both inner folds, - 9 - are in opposition to each other. Indeed, the second hinge fold tends to form in one direction when the first transverse fold is formed in the other. Thus, the formation of the first transverse fold necessarily leads to the formation of the first hinge fold, that is, the outer surface of the dorsal portion 21 of the hinge tends to come into contact with the outer surface of the hinge. lateral portion 22 of the hinge. This movement o, nduit simultaneous rectification of the side panel 23. Given respective provision of the hinge folds 41,42,43, when the two parts 21,22 are in contact with each other, the bottom 11 the back 12 and h side panel 23 are perpendicular to each other.

  Simultaneously forming the third transverse fold 33 and the third fold of: hinge 43, that is to say by folding the blank so as to bring the inner su side of the second flap 14 with the inner surface of the faith d, the dorsal portion 21 of the hinge is held substantially in contact with the back, so that it helps to keep the bottom, the back and the side panel in this position, each perpendicular to the other two.

  Furthermore, by pressing the first flap 25 on the first flap 13, the first margin ply 44 is caused to f; rmation, that is to say that the inner surface of the margin 24 comes opposite. of the inner surface of the bottom 11, and pependicularly to the side panel.

  If the second transverse fold 32 and the second margin fold 45 are formed simultaneously, that is by folding the blank so as to bring the inner face of the first flap 13 closer to the inner surface of the blank. fon ^, the first flap is held against the first flap, which tends to erect the side panel 23 relative to the back.

  Folding: completely the first flap 13, as illustrated in Figure 2, it formr thus, between the bottom, the back, the side panels, the margin and the prè -nier flap, a box 1 able to contain a object, for example a ch (put 3. It is sufficient to fold the second flap 14 on the first to make ler box, as shown in Figures 3 and 9.

  Another process for forming such a box is to first bend the 1 year 2 along the side fold 30, so that the inner surfaces of the side bones 20 come into substantially contact with each other. the inner surface Jre of the central strip 10. Then, according to this other method, the second transverse fold 32 is folded to bring the respective inner surfaces of the first flap 13 and the bottom 11 together, until that the first flap 25 of each side band is in contact with the margin re5 perspective 24. The first transverse fold 32 and the second folds of margin 45 are not superimposable, this necessarily causes the straightening side panels 23. It creates and the volume of the box, which remains e 1 form as the first flaps are in contact with the respective margins.

  To finish forming the box, it is then necessary, as previously written, to form the first and third transverse folds.

  To observe the contents of the box, it suffices to note the second part. The contents of the box appear without any need to remove it or derive the box. This is particularly valuable, for example when the object is offered.

  Such a thing is particularly suitable for the presentation and sale of clothing. The triangular shape of the side panel is particularly suitable for the packaging of a shirt, the neck having an extra-thick It can thus, substantially in the same volume with a bowl. pastry store two shirts, each in its box, instead of u ie single shirt.

  Furthermore, in the embodiment of FIGS. 6 to 9, before folding the first flap 13, the tongue is folded on itself, as illustrated in the thread 7, so that the orifices 54 are substantially vis-à-vis one another. As illustrated in Figure 8, is then introduced through the two holes 54 a lace 58. The lace comprises an end knottedE itself. This end is disposed so that it is within the box, and a free end of the lace extends beyond the outer face of the first flap 13. When closing the 2881110 - 11, it is possible to introduce this free end into the other orifice 57, through the slot 55. By forming with this free end another node on IE second flap 14, the box 1 is thus kept closed. as shown in FIG. 9.

  Of course, the invention is not limited to the examples just described and many adjustments can be made to these examples without being within the scope of the invention.

  Thus, the flaps can be triangular and join substantially the ng of a diagonal to the openable side of the box.

  The function of the first and second flaps is, once the second margin fold and the third hinge fold formed respectively, to hold in position the dorsal part and the margin, respectively. Thus, the shape and dimensions of the flaps can be any, provided that they allow these folds to be formed. Their forms can therefore be essentially coorative, or reduced compared to the examples described.

  The margin for the primary function of straightening or maintaining the respective lateral pannez relative to the background. It also has a sealing function, at least to hide from view the contents of the box, which could be visible or escape between the flaps and the side panel.

  It allows the! if to stiffen the side panel. Rather than being triangular, the ridge can be reduced to a band of small but sufficient width, extending along the first margin fold.

  Instead of being triangular, the side panel may be trapezoidal, or more generally quadrangular. It is then advantageous to provide in particular a hinge on either side of the panel, so two backs, vis-à-vis each other, to the right of each of these hinges.
