Description

TRANSPORTATION AND PRESENTATION ASSEMBLY OF AT LEAST ONE OBJECT This

  The invention relates to a crate for transporting and presenting at least one object. There is a need to benefit from a transport case which can also be used for the presentation of the conditioned object or objects.

  There is still a need to facilitate the automation of the packing operations of one or more objects in a box for both the transport and the presentation of this or these objects within the radius of a particular store.

  There is still a need to benefit from a box compatible with an automated bulk, able to effectively protect the object or objects packaged inside while using for economic and ecological reasons the least possible material.

  There is still a need to benefit from a crate reducing the risks of bad creasing.

  Finally, there is a need to facilitate the placing of objects in a store, in particular by reducing the operations of handling objects and especially the actions necessary to open the box. Patent application FR 2 843 733 discloses a transport case that can be transformed into a display unit by means of a precut system extending around the entire periphery of the box. The box has four side faces, two large and two small, a pre-cut line extending around the entire periphery of the box being formed in each of the faces. To reinforce the box, an insert is provided inside the box, in the form of double wall extending over the entire height of at least two side faces of the box so as to stiffen them.5 A disadvantage of this packaging is due to the fact that the shape of pre-cuts on the periphery of the box is not suitable for crates shaped by folding the large side faces relative to the bottom, since the pre-cuts formed in these faces are slightly inclined relative to the edge that needs to be bent. They are indeed close to being parallel to these edges so that during shaping, the face will tend to bend at the precut instead of bending at the edge separating it from the bottom.

  In addition, the presence of an insert to strengthen the body does not facilitate its opening. To separate the upper part of the box from the lower part, it is indeed necessary to separate two by two the upper parts of the two large faces of their lower part, then the upper parts of the two small faces of their lower part. Once the upper part is completely disengaged from the lower part, the user must lift the upper part with the insert which is secured to it away from the lower part. The presence of the insert thus complicates the separation of the upper part of the box from the lower part to form the display and also increases the manufacturing cost of the box.

  The invention aims to remedy all or part of these disadvantages and to meet all or part of the needs expressed above.

  It achieves this through a box, in particular cardboard, for transporting at least one object, comprising a bottom, an upper face and side faces connecting the bottom to the upper face, a line of least resistance being provided in less a first lateral face to allow to separate an upper part of this face remaining integral with the upper face of a lower part of this face remaining secured to the bottom, the line of weakness passing through the first side face from a second side face adjoining to a third adjacent lateral face, along a line which increases towards the upper face and which decreases towards the bottom, the position of the highest point of the line, along an axis perpendicular to the plane of the bottom, being spaced from the position the lowest point along this axis, a distance at least equal to half the height of the first side face.

  The line of least resistance being formed in a lateral face, over its entire length, through a maximum and a minimum which are relatively spaced apart from each other, it is possible to make a line of least resistance relatively inclined with respect to edges of the face in which it is arranged. Thus, when folding the edges of the face when it is shaped, it limits the risk that the face is folded along the line of least resistance.

  The highest point of the line of least resistance may be located at an upper edge of the first side face, adjacent to the upper face. It will be easy to initiate the separation of the upper part of the face of the lower part from the highest point of the line of least resistance which can easily be grasped.

  The highest point of the line of weakness of the first side face may be located midway between the second and third side faces. By centering the highest part of the line of least resistance by which we will initiate the separation, it limits the efforts required to separate the two parts of the first side face along the entire length of the line of weakness.

  The lowest point of the line of weakness can be located at a lower edge of the first side face, adjacent to the bottom. This maximizes the slope of the line of least resistance which extends over a large part of the height of the first lateral face so as to make the line of least resistance as oblique as possible edges that delimit the first side face.

  The lowest point of the line of least resistance may be located at an edge adjacent to the second or third side face. This makes it possible to connect the line of least resistance of this first lateral face to a line of least resistance formed on the lower edge of the second or third adjacent lateral face. The edge of the second or third lateral face separating it from the bottom is thus used to form a line of least resistance in this second or third lateral face. This avoids forming a line of least additional resistance in this face.

  The highest point of the line of weakness may be adjacent to an opening. This opening allows access to the interior of the body for the user who can grasp the part of the first face to separate from the rest of the first face. The opening may be formed in the upper face of the body. This allows to separate the part of the first side face in a movement perpendicular to the face, ergonomically. In addition, positioned in the upper face, the opening is very visible which encourages the user to introduce the fingers.

  The line of least resistance may be curved. The line of least resistance may in particular be convex towards the upper face. This optimizes the resistance of the face, since it does not tend to bend along the curved line during the shaping of the body, while facilitating the separation according to this curved line. The formatting of the box can be done at a high rate.

  The line of least resistance may comprise at least one pre-cut, including a cut line, over the entire thickness of the face, according to dotted lines. The dots may be longer or shorter, their length may vary along the same line of least resistance. The line of least resistance may also include a cut half-flesh, namely on only part of the thickness of the face. Such a cut is particularly suitable for crates made of cardboard. The mid-cut may extend continuously over the entire length of the line of weakness or in dashed lines. We can also alternate the different types of cutting in the same line of least resistance.

  The first lateral face having a line of least resistance may also comprise a creasing, that is to say a groove intended to form a fold line, intended to force the first face to bend along this creasing when cutting the line of least resistance. It is thus possible, if necessary, the face to deform without tearing during the separation of the two parts of the face.

  Creasing may be formed on the inner surface of the first side face to orient the folding. Being on the inner surface of the face, the creasing does not affect the aesthetics of the lower part of the box to form the display of which it is part.

  The line of least resistance can cross a fourth lateral face opposite to the first. The first and fourth side faces may be symmetrical. The gesture necessary to open the box, is thus simplified.

  The box may comprise a carton or the like, especially corrugated or flat board.

  The invention will be better understood on reading the following detailed description of nonlimiting exemplary embodiments thereof, and on examining the appended drawing, in which: FIG. schematically, flat, a sheet for making a box according to the invention, - 2 shows in elevation the rear of the box, - Figure 3 represents in elevation the front of the box, 25 - the FIG. 4 represents in elevation one side of the box, FIG. 5 represents in perspective the box seen from above, FIGS. 6 to 8 represent views of different stages of opening of the box, FIG. in perspective, the portion of the box 30 forming a display containing a plurality of objects, and - Figures 10 and 11 show an alternative embodiment of the box. FIG. 1 shows a sheet 10, in particular made of cardboard or the like, intended for producing the body of an assembly according to the invention. The sheet may be corrugated but may also be of cardboard.

  The sheet 10 has four faces 20, 30, 40 and 50, of substantially rectangular shape, intended to form respectively the bottom, the large side faces and the upper face of the box, the faces being successively interconnected by their larger edges .

  The face 20 intended to form the bottom of the box, is delimited by four edges 21, 22, 23 and 24. The two large edges 21 and 22 are parallel to each other and are respectively connected to two lateral uprights 30 and 40 intended to form the two large side faces of the box.

  The two small edges 23 and 24, respectively perpendicular to the edges 21 and 22, are connected to flaps 25 and 26, substantially rectangular, which are intended to form part of the small side faces of the body, also called rear face 80 and face before 90. The edges 23 and 24 constitute fold lines.

  The flap 25, corresponding to the rear of the box, has a free edge 27, substantially parallel to the edge 23 which connects it to the face 20. An indentation 29 of semicircular shape, is formed substantially in the middle of the free edge 27 As will be seen in detail in the following description, this notch forms an access opening to introduce one or more fingers to open the box.

  In contrast, the flap 26, corresponding to the front of the body, also has a free edge 28, substantially parallel to the edge 24 which connects to the face 20. The free edge 28 is this rectilinear. A notch 29 'of semicircular shape may be formed in the flap 26, from the edge 24 and substantially in its middle.

  The bottom 20 is connected, on one side, to the lateral upright 30 by the edge 21 common to these two faces. The lateral upright 30 is further delimited by three other edges 31, 32 and 33.

  The edge 31 corresponding to the rear edge is connected to a flap 34 of substantially rectangular shape, and constitutes a fold line. The flap 34 has a pre-cut line 37 formed at half of the flap, and extending over the entire height of the flap. This line 37 separates the flap into two parts, a lower part 34b and an upper part 34a. Preferably, the precut line 37 is cut along the entire length of the flap except at a point 37a located at a distance from the free edge of the flap 34, but close enough to the edge to hold the flap and to be able to be detached with sufficient force .

  In contrast, the edge 32 corresponding to the front edge, is also connected to a flap 35 of substantially rectangular shape, and is a fold line.

  Finally, the edge 33 parallel to the edge 21 is connected to a tongue 36 of substantially rectangular shape. The tongue is used for fixing the lateral upright 30 on the upper face 50 on which it is for example glued or fixed by any other means. An opening 38 in the form of a semicircle is formed in the tongue from the edge 33, substantially in the middle. This opening 38 also serves, as will be seen in detail in the following description, access to introduce one or more fingers to open the box.

  The bottom 20 is connected, on a second side, to a lateral upright 40 by the edge 22 common to these two faces. The lateral upright 40 is further delimited by three other edges 41, 42 and 43.

  The edge 42 corresponding to the rear edge is connected to a rear flap 44 of substantially rectangular shape, and constitutes a fold line. The flap 44 has a pre-cut line 46 formed in the half of the flap, and extending over the entire height of the flap. This line separates the flap into two parts, a lower part 44a and an upper part 44b. Preferably, the precut line 46 is cut along the entire length of the flap except at a point 46a located at a distance from the free edge of the flap 44, but close enough to the edge to hold the flap and to be able to be detached with sufficient force .

  In contrast, the edge 43 corresponding to the front edge is also connected to a front flap 45 of substantially rectangular shape, and constitutes a fold line.

  Finally, the edge 41 parallel to the edge 22 is connected to the face 50 intended to form the upper face of the body.

  The face 50 intended to form the upper face of the box is delimited by the edge 41 common with the face 40 and three other edges 51, 52 and 53. The two large edges 41 and 53 are parallel to each other, the edge 53 being free in the example shown. The two small edges 51 and 52, respectively perpendicular to the edges 41 and 53, are connected to flaps 54 and 55, substantially rectangular, which are intended to form part of the front and rear faces of the body. The edges 51 and 52 constitute fold lines.

  The face 50 has two openings 56 and 57. A first opening 56 is contiguous to the side face 40 and formed along the edge 41, substantially in the middle of this edge. According to the illustrated example, the opening 56 is delimited by a semicircle formed in the face 50, and by the upper edge of the face 40, rounded as will be seen in the following description. The second opening 57 is formed by a notch in the form of a semicircle formed substantially in the middle of the free edge 53. The second opening 57 of the upper face 50 is provided to be superimposed with the opening 38 formed in the tongue 36, when the tongue is fixed to the upper face 50 when the body is assembled. These two openings therefore advantageously have substantially the same shape.

  Once the box is assembled, the flaps 25 and 54 are intended to form the rear face 80 of the box and the flaps 26 and 55 are intended to form the front face 90 of the box.

  All the flaps and the tongue of the body have a substantially rectangular shape, namely a slightly trapezoidal shape to leave a play between the different faces and facilitate the mechanization of the formatting of the body.

  To allow easy opening of the crate when assembled, a line of weakness extends over the entire periphery of the body. According to the illustrated example, this line of least resistance consists of pre-cuts provided on the periphery of the box which separates the upper part of the box from the lower part so as to form a display for the objects contained in the box . In a particular example, the line is cut, in the entire thickness of the carton, according to dashed lines. Alternatively, the line of least resistance may comprise a cut half-flesh, namely on only part of the thickness of the cardboard. The mid-cut may extend continuously over the entire length of the line of weakness or in dashed lines. We can also alternate the different types of cutting in the same line of least resistance.

  In particular, a precut 60 is formed in each lateral upright 30 and 40, symmetrically, a portion 60a being formed in the lateral upright 30 and a portion 60b being formed in the lateral upright 40. To simplify the description, only the amount lateral 40 will be described in detail, the lateral amount 30 being symmetrical with respect to the median plane of the body.

  As seen in detail in Figure 4, a portion 60b of the pre-cut 60 formed in the lateral upright 40 separates it into two parts, a lower portion 40a for forming a portion of the display and a top 40b.

  The precut 60b extends along a curved line along the entire length of the lateral upright 40 between the two adjacent lateral faces, namely the front face 90 and the rear face 80. The precut line 60b extends from a first end 63b located at the rear edge 42 of the face, from the middle of this edge where it joins the pre-cut line 46 of the flap 44, to a second end 62b located at the front edge 43 of the face, to the end of this edge 43, where it joins the edge 22 of the bottom. This rounded precut line 60b passes through a vertex 61b confused with the edge 41 of the lateral upright 40, substantially in the middle thereof. In particular, the top 61b of the rounded precut line is adjacent to the opening 57 formed in the upper face 50.

  The position of the top 61b of the precut on an axis perpendicular to the plane of the bottom, namely on an axis parallel to the edges 42 or 43, is separated from the position of the lowest point 62b by a distance h corresponding to the entire height of the lateral upright 40. In addition, the position of the top 61b on the axis is separated from the position of the first end 63b of the line by about half the height of the upright. The precut line 60b therefore has a shape very far from a line parallel to the edges 22 and 41 of the lateral upright 40 so that there is little risk that the lateral upright 40 will bend along the line 60b when of the shaping of the box and in particular during the folding of the edges 22 and 41.

  The length of the pre-cut line is not the same on each side of the top. In particular, the line 60b is longer between the vertex 61b and the second end 62b than between the vertex 61b and the first end 63b. As a result, the line 60b disengages more rapidly to the first end 63b than to the second end 62b. To prevent the lateral upright 40 from tearing at the end 63b, a creasing 70b is formed between the top 61a and the first end 63a to force the lateral upright 40 to bend along this creasing when the separation of the pre-cut 60b. This creasing is rectilinear and is provided on the surface intended to be inside the body when it is assembled so as not to harm the aesthetics of the body. It is preferably made by a line of reduced thickness of the lateral amount.

  All edges of the faces defining fold lines may have a precut to facilitate the folding operation during the shaping of the body. In particular, the edge 24 separating the bottom 20 of the front flap 26 is pre-cut.

  The assembly of the sheet 10 intended to form the box can be performed in the following manner, which will now be described.

  In Figures 2 to 5, the box is shown assembled and set volume. The volume can be automated.

  The sheet of the box is first laid flat in a magazine. The face 20 forming the bottom of the box is held by suction and the lateral uprights 30, 40 and the flaps 34, 35, 44 and 45 are raised by folding folding lines 21, 22, 31, 32, 42 and 43.

  O objects are available, for example identical on the face 20 forming the bottom, preferably in an orderly manner, for example in rows. Objects O are for example constituted by devices for packaging a product, especially a cosmetic product, for example pots or other objects, possibly themselves in boxes. The storage steps of the objects O can be performed automatically.

  The tongue 36 is then folded along the fold line 33 and a line of glue is placed on the top of the tongue. Folding the upper face 50, along the fold line 41, is fixed on the tongue.

  Glue lines are deposited on the flaps 25, 54, 26 and 55 in order to close the rear and the front of the body.

  The back of the box is closed by folding the flaps 25 and 54 along the lines 23 and 51, which are glued on the flaps 34 and 44 so as to form the rear face 80 shown in FIG. the box is closed by folding the flaps 26 and 55 along the lines 24 and 52, which are glued on the flaps 35 and 45 so as to form the front face 90 shown in FIG.

  During this assembly, the precut lines 60a and 60b do not tend to break because of their rounded shape which makes them more resistant since a fold is only in a straight line and not in a curved line. The assembled box is shown in Figure 5.

  For the opening of the box, one can proceed as follows, with reference to Figures 6 to 9. 10 After transport, the user opens the box by removing the parts of the lateral uprights delimited by the precut lines 60a and 60b. As seen in FIG. 6, the user introduces one or more fingers into the openings 56 and 57 formed in the upper face of the box and separates the lower parts 30a and 40a from the two lateral uprights 30 and 40 from the rest of the box. the box, according to a movement perpendicular to the face. The two parts 30a and 40a of the lateral uprights are spaced in opposite directions. The precut line is sheared without the risk of tearing due to the perpendicular movement which allows to separate the two parts which separate by departing orthogonally. The portions 60a and 60b of the precut line 60 do not have the same length on either side of their top, the lateral uprights tend to bend when the precut is completely detached from the shorter side while the The user always discards the amount in order to separate the other side of the line. The presence of grooves 70a and 70b forces the post to bend properly along this crease.

  Once the two lines 60a and 60b are fully disengaged, the user can lift the upper part of the box, through the rear portion 30 thereof as seen in Figure 7. The user introduces one or more fingers in the opening 29 formed in the rear flap 25 and spreads the flap 54 of the rest of the box, again in a perpendicular movement to the rear face. The upper part 34a and 44a of the flaps 34 and 44 being glued to the flap 54, these two parts tend to follow the movement of the flap 54 which will cause the breaking of the attachment points 37a and 46a. The attachment points 37a and 46a being located at a distance from the opening 29, this will facilitate the opening of this part since the uncoupling is already initiated. In addition, the position of the opening allows to enter the flap 54 in an area near the attachment points. The upper rear portion is thus disengaged from the lower rear portion since the rupture lines 37 and 46 respectively join the rupture lines 60a and 60b of the lateral uprights.

  The whole of the upper part of the box can then be lifted by the rear of the box as shown in Figure 7, until fully disengage the upper part of the box from the lower part by the edge 24 also precut. An opening 29 'can be used to facilitate the separation of the flap 26 of the face forming the bottom 20.

  This produces the display shown in Figure 9 on which the objects are present. The display is thus formed by the bottom 20 of the box, the lower parts 30a and 40a of the lateral uprights and by the rear flap 25.

  Of course, the invention is not limited to the example just described. The shape of the display can be modified and adapted for example to the nature of the objects and / or the marketing environment.

  In particular, the top 61 b of the pre-cut line may be located at a distance from the upper face 50, the opening 56 then being formed not in the face 50 but in the lateral upright 40.

  Instead of being situated midway between the front face 90 and the rear face 80, the top 61 b of the precut line may be located closer to the front face 90 than to the rear face 80 or vice versa, plus close to the rear face 80 than 30 of the front face 90. For example, the tearing of the line on each side of the top may be balanced by having a developed length of the identical pre-cut line on each side.

  According to another variant shown in Figure 10, instead of joining the lower edge 22 of the lateral upright 40, the precut line can stop halfway up the side edge 43 at its second end 62b. The curvature of the pre-cut line is then the same on each side of the top 61 b. The front face 90 can then dissociate into two parts in the same manner as the rear face 80 so as to obtain the display shown in Figure 11. This display is then constituted by the bottom 20 of the body, the lower parts 30a and 40a of the lateral uprights, by the rear flap 25 and by the front flap 26.

  In a variant, the pre-cut line 60b may comprise at least one rectilinear portion instead of being curved.

  In the foregoing detailed description, reference has been made to preferred embodiments of the invention. It is obvious that variations can be made without departing from the invention as claimed hereinafter.
