Description

The present invention relates to a box for containing an object and

  comprising, formed in continuity in the same folded sheet, a prismatic envelope comprising four sides and a first fastening strip connected to the fourth side of the envelope and intended to be fixed on the inner face of the first side of said envelope. The box further includes a holster disposed within

  the envelope and intended to stall the object it contains.

  The box can, of course, include closure means of

  each of its two ends, for example constituted by flaps.

  Such boxes are frequently used, for example in the field of perfumery, to contain a relatively fragile object such as a bottle. Similar boxes, of any size, can be used in other areas to contain and stall any object

during his transport.

  It is known to make the case using a simple cardboard sheet provided with micro-grooves or corrugations, and folded so as to be inserted into the envelope by having four walls located against the

  internal faces of each side of the envelope.

  A box provided with a case made in this way has various disadvantages mainly related to the fact that the envelope and the case are two

  separate elements made of different materials.

  This increases the number of operations both during manufacture and during assembly. In addition, to limit the volume of empty boxes during transport, they are preferably delivered flat, folded in two diagonally opposite folds. The presence of a separate case in

  cardboard makes this folding difficult and increases the thickness of the folded boxes.

  Moreover, a case formed in this way gives the whole a rather luxurious character, sometimes incompatible with the quality requirements of

  finishing related to certain areas such as that of perfumery.

  To remedy these drawbacks, a holster formed in the same sheet as the envelope and in its continuity, comprising three walls respectively spaced from the corresponding sides of the envelope, has already been used.

  first of these walls being connected to the first fastening strip.

  A box with a case made in this manner is illustrated in Figures 1 and 2 of the accompanying drawings. Figure 1 shows the developed model of the box, while Figure 2 shows schematically

this box seen from the side.

  In this figure 2, we see that the box 10 comprises a primatic envelope 11 which, seen from the side, has a rectangular shape, and an internal shimming case 21. As illustrated in Figure 1, the various elements of this box are formed in the same sheet 9 and separated from each other by folds such as 9 '. The envelope 11 has four sides

  respectively designated by references 12, 14, 16 and 18.

  The box also comprises a first fastening strip 20 connected to the fourth side 18 of the envelope by a fold and intended to be fixed on the inner face of the first side 12 of this envelope. The first wall 22 of the case 21 is connected to this first fastening strip 20 by a fold, and the other three walls of this case 24, 26, 28, as well as a band

  are made in the continuity of this first wall 22.

  Three of the walls of the case 22, 24, 28 are spaced from the corresponding sides of the envelope 11. Being of smaller dimensions than those of the envelope, the case is adapted to the setting of the object that can contain the box . When the box is set in volume as in Figure 2, the case 21 is fixed by three strips: the first fastening strip 20, the entirety of its

  third wall 26, and the strip 30.

  The third wall 26 of the case 21 being contiguous to the fourth side 18 of the casing 11, it is understood that it has no real use from the point of view of the wedging. Because of this, and also because the width of the first fastening strip 20 is equal to that of the case 21, the amount of material used to make the case 10 is excessive. In addition, the setting volume is tricky because it requires properly fold the strip 30 against the inner face of the first wall 22 of the holster in one place

  of the box that is difficult to access.

  This excessive consumption of materials, as well as the difficulty of setting volume, increase the cost, which is a major drawback when we consider the quantity

  important number of copies made.

  The present invention aims to overcome these disadvantages and proposes a box of the aforementioned type, the case is formed in the same sheet as the envelope, and which comprises a second fastening strip directly connected to the third side of the case and intended to be fixed on the inner face of the first side of the envelope. This box further comprises at least one stand for fixing the case, cut in the portion of the sheet which constitutes said case, this stand having a fixing portion intended to be fixed on the internal face of one side of the case. facing envelope and a bracing portion connecting said attachment portion to the case and for maintaining the latter at a determined distance from said side of the casing. Thanks to this conformation, the three walls of the case are perfectly o0 maintained spaced from the corresponding sides of the envelope, a substantial saving in material is achieved since it is not necessary that this case has a fourth wall, and the setting volume is simplified since the fixing of the first and second binding strips and that of the fastening portion of the stand are particularly easy

as we will see later.

  The invention will be better understood on reading the description

  following detailed description of embodiments given by way of non-limiting examples.

  The description refers to the accompanying drawings in which:

  FIGS. 1 and 2 illustrate, as previously seen, a known box, FIG. 3 represents a developed model of a box according to the invention, FIG. 4 is a perspective view of the same box. volume setting, with parts torn off, - figure 5 is a schematic side view of this box, - figure 6 shows a developed model of a box according to another embodiment, - figure 7 shows a developed model of a box according to yet another embodiment, - Figures 8a, 8b and 8c show three stages of folding and

setting volume of the box.

  Figure 4 shows a box for containing an object and which, as seen in Figures 3 and 5, is made in the same sheet 41 folded. The box 40 has a prismatic outer envelope 42 comprising four sides 44, 46, 48 and 50. These sides are separated from each other by folds such as the fold 41 'of the sheet 41. These folds are by

  example made by a local crushing of the sheet.

  The box also comprises a first fastener strip 52 connected to the fourth side 50 of the envelope 42 and, as seen in Figure 5, intended to be fixed on the inner face of the first side 44 of this envelope. The box further comprises a case 54 always formed in continuity in the same sheet 41. When the box is placed in volume, the case 54 is disposed inside the envelope 42 and serves to wedge the object that can contain the box. This case comprises three walls 56, 58 and 60 which, always when the box is placed in volume, are spaced apart from corresponding sides of the envelope 42. In the example shown, the wall 56 is spaced from the side 50, the wall 58 is spaced from the side 48, and the wall 60 is spaced from the side 46. The first wall of the case, designated by the reference 56,

  is connected to the first fastening strip 52.

  The box comprises a second fastening strip 62 which is connected to the third side of the case 54 and which is intended to be fixed on the inner face of the first side 44 of the envelope 42. The distance between the two

  fastening strips determines the length of the holster.

  In the example shown, this second band 62 is folded to the left of the third wall 60 to be glued to the side 44 of the envelope; if the spacing between the wall 60 and the side 46 is sufficient, this second band 62 may equally well be folded to the right in position opposite to that shown in Figure 5 to be glued on the same side

44.

  The box 40 comprises at least one stand 64 for fixing the case 54, cut in the part of the sheet 41 which constitutes this case and clearly visible on the cutaway part of FIG. 4. The stand has a fixing portion 64a intended to , as shown in FIG. 5, to be fixed on the internal face of one side of the facing envelope, and a spacer part 64b connecting this fixing portion 64a to the case 54 and intended to

  to maintain the latter at a determined distance from said side of the envelope.

  In the example shown, it is the third side 48 of the envelope which is opposite the fixing portion 64a. As we will see in the following, the opposite side may equally well be the second or the fourth

side of the envelope.

  In the box of FIG. 4, which is only an exemplary embodiment, the first and third sides 44 and 48 respectively constitute the main rear and front faces of a conventional box and the second and fourth sides 46, 50 in constitute the lateral faces. If the first side is a side face, the distance between the two fastening strips will determine the

width of the case.

  To simplify the description, the term "face" will be used in the following

  to designate the inner face or the outer face of an element, the inner face being that which is directed towards the center of the envelope while the face

  external is the one that is directed outwards.

  The box 40 may include means for closing its lower and upper openings and, once closed, have the shape of a rectangular parallelepiped. In known manner, these closure means may comprise a flap 66 having a first end connected to the end of one side of the envelope by a fold 66 'and an opposite second end provided with a re-entrant lug 68. These closing means

  may also include side flap tabs 70a and 70b.

  Fixing the two fastening strips 52 and 62 and the fastening portion 64a of the stand can be carried out using an adhesive, for example in the case where the sheet 41 is made of cardboard, or by heat-sealing, by

  example in the case where this sheet is made of synthetic material.

  If we compare Figure 3 to Figure 1, we note that equivalent dimensions of the envelope and the case, the amount of materials used to make the box according to the invention is significantly lower than that which is used for the box of Figure 1. This is due to the fact that the case according to the invention may have only three walls and that the width of the first fastening strip 52 is equal to the spacing of the wall 56 of the case

  relative to the side 50 of the envelope and not to the width of the case.

  For better efficiency, the height h of the crutch is

  advantageously significantly less than the height H of the case.

  Although the figures show, for each box, only one crutch, it is possible to provide two or more crutches, which can be arranged symmetrically. The conformation of Figure 4 shows that the case is attached to two sides of the envelope, but depending on the number of crutches can also fix this case to three or four sides. When, as in the figures, only one crutch is present, it is

  advantageously located in height in the middle part of the case.

  The width of the first fastening strip 52 being much smaller than that of FIG. 1, and the height of the stand is much lower than that of the case, when glue is used to secure the surface, to glue is significantly less important in the box

  according to the invention than in that of FIG.

  The crutch or crutches can be cut, "on horseback" on several of the walls of the holster. However, as in the examples shown, the stand is advantageously cut into one of the walls of the case. In this case, as shown in Figure 3, it is preferably cut into the walls of the holster whose width is maximum. Thus, in Figure 3, the stand 64 is cut in the second wall 58 of the case, which happens to be the main wall of this case. In contrast, Figure 6 shows a case 74 having first, second and third walls respectively designated by references 76, 78 and 80; the second wall 78 is also to be the main wall of the case. However, in this example, the stand 84 which includes the attachment portion 84a and the portion

  spacer 84b is cut in the third wall of the case 80.

  It is advantageous that, as in FIGS. 3 and 6, the stand 64, 84 is entirely cut in one of the three walls 58, 80 of the case 54, 74 and is connected to this case in the region of the case. edge 57, 79 between this wall 58, 80 and the neighboring wall 56, 78. The embedding portion 64b, 84b is then located in extension of this adjacent wall 56, 78, and the fixing portion 64a, 84a is folded relative to this part of the brace to be fixed on the inner face of the side of the casing located opposite the wall of the case in which the stand is cut. In the examples shown, the fixing portion 64a of the stand of FIG. 3 is intended to be fixed on the internal face of the third side 48 of the envelope, while the fixing part of the stand 84a of FIG. intended to be fixed on the inner face of the second side 46 of the envelope. This is a kind of natural conformation when, as previously indicated, the bracing portion of the stand is located in extension of the adjacent wall. It is also possible to fold this spacer part in the continuity of the edge 57, 79 which separates the wall in which the stand is cut from the adjacent wall, and to stick the attachment part on another side of the wall. 'envelope. However, this additional fold introduces

  an articulation sometimes undesirable.

  As previously indicated, the various walls of the case are delimited in width by folds. To facilitate the folding of the case, at least some of these folds may have incisions. This is for example the case of the folds 53, 59 and 61 of the case of Figure 3, which respectively separate the first fastening strip of the first wall of the case, the second and third walls of the case and this third wall and the second fastening strip. The incisions are schematized by broken lines. Still in FIG. 3, the fold 65 which separates the fixing portion 64a from the stand from its spacer portion 64b presents

also such incisions.

  In FIG. 6, it can be seen that the first and the third walls 76,

  of the case 74 have, at one of their ends, V-shaped cuts 86.

  When the box is put in volume, these notches 86 are facing one another. In this arrangement, they are able to retain any protruding parts of the object contained in the box to prevent its movement in the case. It is also possible to provide similar notches in the second wall of the holster, of any shape and arranged or

  not to one end of this case.

  Referring now to Figure 7, we see a case 94 identical to that of Figure 3, but which further comprises means for closing at least one of its lower and upper openings. The closing means of one of the openings comprises a tongue 96 secured to one of the walls of the case, in this case the wall 58. This tongue 96

  may include a flap tab 97.

  Still in Figure 7, we see that at the other end of the case 94, a locking flap 98 is provided. This flap 98 is secured to the second wall 58 of the case and has a shape adapted to cooperate with one of the

  ends of the object that can hold the box to keep it secure.

  In the example shown, the flap comprises a central opening 100, for example able to cooperate with the cap of a bottle. The flap also includes a flap tab 102 and a median ply 99 which serves to deform it to bring it back inside the case to better block the end of the object. It is also possible to provide two lateral flaps respectively secured to the first and third walls of the holster, in order to grip one of them.

  ends of the object to block.

  With reference to FIGS. 3 and 4, it has previously been indicated that the box could comprise means for closing one of its upper and lower openings. In the embodiment of these figures, towards one of the ends, these means are constituted by a folding external tongue 66 provided with a re-entrant tab 68 which, in the closed position of the tongue, is placed against the inner face the first side 44 of the envelope. In this case, the ends of the first and third walls 56, 60 60 of the case 54 near the opening considered advantageously each have a cutout designated by the references 71a and 71b in FIG. 3. These cutouts 71a and 71b each determine a housing visible in Figure 4 under the references 72a and 72b and which is adapted to receive the re-entrant lug 68 between the walls 56 and 60 of the holster and the face

  internal of the first side 44 of the envelope.

  With reference to FIGS. 8a to 8c, the method of

  folding and setting volume of the box.

  FIG. 8a represents, as seen on the edge, the sheet 41 of FIG.

  For ease of understanding, we have marked the various folds that separate the sides, the fastening strips and the walls of the various elements of the box by extra thicknesses. The crutch is schematized in the same way. The fold 47 which separates the second and third sides 46, 48 of the envelope, the fold 51 which separates the fourth side 50 of the envelope and the first fastening strip 52, and the fold 59 which separates the second and the third walls 58, 60 of the case are referenced. These folds constitute major folds according to which the folding of the sheet before delivery will be carried out, the other folds being of course preformed in this sheet but only being used when, starting from the configuration of FIG. 8c, the box is put in volume as in figure 5. Figure 8c shows the configuration of the box

  when it is delivered and Figure 8b is an intermediate step.

  At first, the case is folded over the envelope according to the arrow F by pivoting around the fold 51 to arrive in the configuration of Figure 8b. In this configuration, the fixing portion 64a of the stand is already facing the internal face of the side of the envelope

on which it will be glued.

  For ease of understanding, in FIG. 8b as in FIG. 8c, the view is slightly exploded, that is to say that some of the elements actually in contact are spaced apart from one another and that the folds

  correspondents are symbolized by dots.

  To move from the configuration of Figure 8b to that of Figure 8c, the third wall of the case is folded on its second wall along the arrow G around the fold 59, and the first and second sides of the folded envelope on the assembly according to the arrow H around the fold 47. The parts intended to be fixed on each other may be previously glued, as o0 indicate the hashings of Figure 8c; when the sheet is folded as in this figure, the simple action of a press can paste the box. We thus obtain a very compact box which uses only a minimum volume to be delivered and which can be put in volume by a simple gesture to arrive at the

configuration of Figure 5.
