• It may comprise an opening means which defines in the packaging, - after a first opening of the latter -, a body and a covering cover and in that the part of the packaging constituting said body are associated with means making it possible to deform it so as to reduce the perimeter of its opening so that it can be closed by fitting the styling cover over it.
• the first opening means is a pre-cut strip over substantially the entire side wall of the packaging and which is preferably provided with a gripping tab making it possible to facilitate its tearing off.
• the means associated with the body for the deformation of the perimeter of its opening edge are constituted by at least one line of ramage formed on the side wall of the body, advantageously by one or non-traversing ⁇ ecoupeis (s) in the thickness of the blank constituting the packaging.
• the packaging has a cylindrical lateral surface, - in the general sense of this term -, and at least one of said rowing lines is oblique to the direction of the generatrices of the cylinder.
• the row (s) of rowing is (are) parallel (s) to said generators.
• the invention also relates to a method for producing a packaging from a blank as defined above, and comprising the following steps: a_) forming from the blank a case set in volume b) folding substantially at an angle at least one intermediate flap of the first and / or second series c) fold the first flap substantially at right angles, the latter coming into contact with at least one said intermediate flap folded during step bd) substantially fold a right angle the intermediate flaps not yet folded to stick them on the first glued regions of the external face of the first folded flap e) fold the second flap substantially at right angles to fold it over second glued regions of the folded intermediate flaps and / or the external face of the first flap.
• the process can be characterized in that it includes, after step e, or between steps a and b, a step f_ of inserting a product in the case.
• FIG. 1 is a schematic perspective view of a package according to the invention before first opening
• Figure 2 illustrates, in exploded perspective, the body and the covering cap of a package according to Figure 1 after first opening thereof;
• FIG. 3 is a perspective view, from the inside, of the styling cover
• FIG. 4 is a flat view of a blank of material, such as cardboard or material having mechanical characteristics similar to those of cardboard, from which can be made the package 1 according to the invention;
• FIG. 5 is a flat view of a preferred embodiment of the blank according to the invention, and Figure 6 shows said folded blank.
• the packaging made of sheet material, such as cardboard or material having mechanical characteristics analogous to those of the carton, with a cover with a snap closure is a box 10 intended for the packaging of food products such as biscuits B, without this indication having, however, any limiting nature whatsoever.
• the package 10, Figure 1 comprises a cylindrical side wall 11, and two parallel end faces whose outline, as shown for the face 12, is centrally symmetrical around a point O with two curved parts 13, 14 joined together by rectilinear parts 15 and 16, respectively, so that the side wall 11 has two curved faces and two flat faces 20 and 21 which allow these packaging boxes to be joined together for their transport and presentation on sale.
• the packaging box 10, - produced as will be explained below from a single blank 25 of sheet material such as cardboard or the like -, comprises means 26 for first opening which, when they are made operational , separate said packaging into a box body properly has 30 and a covering cover 31.
• the means 26 are housed by a strip 32 cut in the blank 25, between its edges 27, 28 (FIG. 4) and which is provided with a gripping tab 33 which, when pulled by the user ⁇ in the direction of the arrow f_, causes the strip to be torn over the entire side wall 11 of the packaging without it appears on the body 30 or the throat or rim cover 31 of the type of those known, for example, in cardboard boxes of cigarette packets.
• the packaging box which has just been described, and which is mainly intended to enclose a content whose volume can decrease by successive withdrawals, such as cookies, on the one hand, and which one wishes to be able to keep while having the possibility of closing it, on the other hand, comprises means intended precisely to allow this reclosing by fitting the covering cover 31 onto the body 30.
• said means are arranged so that a slight pressure in the preferred areas of the body causes a reduction in the perimeter of the opening 35 of the latter and, in the embodiment described and shown, said means are constituted by rowing lines 36, 37 and 38, 39 formed by non-through cuts in the thickness of the planar faces 20 and 21, respectively, of the side wall of the packaging box; as can be seen in FIGS. 2 and 4, said row lines 36-39 are directed obliquely with respect to the generatrices of the side wall, by forming inverted V's whose points 40 and 41, respectively, are in the vicinity of the opening 35 body 30.
• a single ra line directed parallel to the generatrices of the side wall is provided substantially in the middle of the planar faces 20 and 21.
• the ra lines as 36-39 are parallel to each other and parallel to the generatrices of the side wall of one package.
• the box according to the invention can be closed, - after part of its contents have been removed -, by deforming the opening 35 of said body by light pressure on it (taking advantage of the slight play between the body and its contents) to bring the opening part of the body in the condition shown in solid lines in FIG. 2 in which its opening perimeter is reduced relative to that of the perimeter with the covering cover 31, so that the latter can be easily placed on the body, as suggested by arrow E in this figure.
• a packaging box according to the invention thus makes it possible to package food products enclosed directly in the box or previously conditioned in an intermediate flexible sheath and this in order to guarantee that no untimely handling has been carried out on the box for as long ⁇ ue the opening strip 32 is present and intact, then to easily close the box after first opening, and subsequent openings, to contribute to the conservation of the product which it encloses.
• the invention provides for making it from a blank 25, FIG. 4, in one piece and which comprises, in addition to the panels 20 and 21, panels 50, 50 'and 51 constituting the side wall and a set of flaps 52 and 53 intended to form, the first, the bottom of the covering cover 21 and the second the bottom to the body of box 30.
• the flap 50 ' is used for bonding on it the panel 21, -to form a cylindrical case-, while the flaps 52 and 53, symmetrical with respect to an average transverse axis XX of the blank, serve to form the fon ⁇ s of the packaging and each include:
• a flap 60 bounded by the domed parts 13, 14 and the straight parts 15 and 16, the latter forming articulation lines on the panel 20;
• a flap 61 of cruciform appearance connects because a hinge _ ⁇ gne 62 to the panel 21; . three intermediate flaps of smaller dimension 63, 64 and 65 connected to articulation to the panel 50 around a line 66; and panels of the same shape as those mentioned last, references 67, 68, 69 connected around a line of articulation 70 to the panel 51, said flaps forming, after folding and gluing, a relatively rigid and resistant cover structure 31 , Figure 3, the flaps 53 of the blank forming a bottom of the body also rigid and resistant.
• the invention is not limited, of course, to the embodiment described and shown. It finds application for packages whose cross section of the side wall is a polygon, for example rectangular or another closed curve, the height of the covering lid being advantageously, - when the contents of the package are in the form of discrete products - , at least the height of one of these products.
• the blank shown in Figure 5 is in one piece and has a first (7) and a second (7 ') panels constituting a first pair of side walls of the package, as well as a third (8) and a fourth (8 ') panels, possibly grooved, constituting a second pair of opposite side walls of the package. In general, it is planned to present the case to the consumer by placing it on one of the walls 8 or 8 '.
• It also comprises two pairs of opposite flaps, respectively (2A, 2B) and (4A, 4B), the flaps 2A, 2B, and possibly the flaps 4A, 4B being, like the flap 60 previously described, delimited by two curved parts 13 ', 14' and straight parts 15 'and 16', the latter forming a line of articulation with the panel 8 ', and possibly the panel 8.
• the flaps 4A and 4B are folded down around a hinge line 71 located in the extension of line 16 ', when the blank is placed flat (Figure 5).
• the panels 7 and 7 ' also have, preferably on both the A side and the B side, intermediate flaps or tabs referenced 1A, 3A and / or 1B, 3B and which are articulated to these panels 7 and 7' around lines 72 and 72 'located in the extension of the articulation line 16', when the blank is placed flat (Figure 5).
• the case 70 may have an opening strip 32.
• two flaps 1 of trapezoidal shape frame three flaps 3 also of trapezoidal shape.
• These shutters 1A, 3A, 1B, 3B have a surface which is considerably smaller than that of the shutters 2A, 2B which they border.
• their shapes and dimensions can be any provided that they are compatible with the process of shaping the packaging in the form of a case, as will be described below:
• the case 70 arrives flat from the printer being already folded along the generator 6, and glued to the bonding tab 5, as shown in FIG. 6.
• the case 70 is inserted in a stack in a so-called cartoner machine. This machine will first of all, conventionally, unstack the case 70 and bring it into position to be shaped.
• the case 70 is then set in volume, by any conventional method of setting in volume.
• the A side is closed first. This closing takes place as follows:
• the flap 4A is glued on the legs 3A.
• a bag of cookies for example, is inserted into the case by the B side of the package. Once the pouch is inserted, we close the B side of the package in the same way as we closed the A side.
• the pouch can be inserted into the case before closing the A side, that is to say after the volume of the case.
• We obtain an optimal quality of shaping of the semi-oval part of the package because the number and size of the legs allow a good adequacy of the sides of the package to the rounded area of its end.
• the implementation is in fact all the more suitable as the number of the legs 3A is more eieve, but also that the size of the legs 1A is smaller.
• the method according to the invention can be implemented on only one of the two sides (A or B) ⁇ e the case 70, or as shown, both on the sides A and B
• the glue lines 18A, 18A ', 18B and / or 18' B can be replaced by glue dots.
• 18B, 18 'B can be arranged on the external face of the corresponding flap 4A and / or 4B and / or on the corresponding tabs 3A and / or 3B.
• the glued regions in particular of the external face of the first 2A and / or of the second flap 2B, are produced in advance.
• the tabs 1A and / or IB which serve as a counterpart to the folding down of the flaps 2A and / or 2B, are preferably end tabs which are adjacent to the straight edges 15 ′ and 16 ′ of the flaps 2A and / or 2B.
