Definitions

• the invention relates to the field of packaging and more particularly the field of packaging obtained from a blank, pre-cut from a sheet of material, in particular from a sheet of cardboard.
• a package according to the invention is particularly suitable for the ordered packaging of elongate objects in a longitudinal direction, including a package for cigars or cigarettes.
• the packaging contemplated by the invention is more particularly packaging comprising a case and a drawer, in which:
• the case comprises four panels opposite in pairs and connected in pairs along four parallel longitudinal edges so that the case delimits an interior space which extends longitudinally and which has a closed quadrilateral cross section;
• the case is open at at least one upper longitudinal end
• the drawer has a cross section complementary to that of the inner space of the case so as to be guided in longitudinal sliding inside the case between at least one retracted position and an extended position.
• the drawer In this type of two-piece packaging, the drawer is intended to contain the products to be packaged but is generally not completely closed. In particular, it may have an opening at a front face to allow access to the products in the drawer.
• the case inside which the drawer is intended to be at least partly received in its retracted position, closes the front opening of the drawer when the drawer is in the retracted position inside the case, preventing thus access to the products and preventing said products from escaping from the packaging thus formed in two pieces.
• a typical example of such a type of product is two-piece match packaging.
• the drawer In its simplest version, the drawer generally has a rear wall, and two opposite side walls and two opposite transverse walls which are perpendicular to the bottom.
• the drawer is thus open only towards the front, in a direction perpendicular to the rear wall, but it is then open over the entire area corresponding to the rear wall.
• the four-panel case has a cross section corresponding to that of the drawer, and vice versa. It can be opened at both longitudinal ends to allow the entry and exit of the drawer in one direction or the other.
• To access the matches contained in such packaging it is necessary to slide the drawer relative to the case to allow access to the front opening of the drawer.
• the matches are arranged in an orderly manner, parallel to each other, in the box, it is necessary, to release a match, to widely open the access by sliding the drawer a great distance, until at an extended position in which the drawer is almost completely out of the case.
• the upper transverse wall of the drawer prevents the matches from going out in a longitudinal direction and, on the other hand, especially when the package is full or almost full, the upper transverse edge of the front panel of the holster prevents a match from tilting forward until you reach that position almost completely out.
• This is problematic in that it is common for the drawer to come out of the case completely, with a reinsertion that is not always easy.
• the matches are no longer held at all and can easily escape the drawer by the front panel.
• FIG. 1 An improved example of a package comprising a holster and a sliding drawer is described in EP-0.189.618-A1.

• the upper portion 26b of the side wall 26 is arranged transversely towards the inside of the slide 10 relative to the lower portion 26a of the side wall considered. Such an arrangement makes it possible to prevent the lower edge 26bi of the upper part 26b from interfering with the case 12 when the drawer 10 is brought down by longitudinal sliding down into its retracted position.
• the blank 16 illustrated in FIG. 1A may comprise two first lower side panels 261 respectively articulated respectively by a premarketed longitudinal fold line, to one of the two opposite longitudinal edges 200a of the lower portion 180a of the rear panel.
• the lower side panels 261 By simple folding of the lower side panels 261, it is thus possible to form the lower portions 26a of the side walls 26.
• the upper edge 263 of these first lower side panels extends longitudinally beyond the level of the axis A1, so as to form the extension 26ap.
• the extension 26ap is made with continuity of material in the lower side panel considered.
• the extension is formed of an insert.
• the upper side panels 262 have a dimension in the transverse direction that is greater than the longitudinal dimension of the upper portion 180b of the rear panel 180.
• This feature allows that, after implementation three-dimensional shape, the upper portion 26b of the side wall 26, thus formed by the corresponding upper side panel 262, extends longitudinally towards the lower part of the side wall beyond the axis of articulation Al.
• other than the upper side panels 262 have free end edges, opposite the longitudinal edges 283, which, in this embodiment, are in an arc. These free end edges form, after three-dimensional formatting of the drawer, the lower edges 26bi of the upper portion 26b of the corresponding side wall.
• the extension 26pp is made with continuity of material in the upper side panel considered.
• the first lower side panels 261 extend longitudinally towards the upper part 180b of the rear panel beyond the pre-articulated transverse fold line 360 of articulation between the two parts of the rear panel, then found the feature mentioned above to have overlapping surfaces of the two portions 26a and 26b of a side wall 26 which are distributed on each side of the axis Al.
• the lower portion 26a of the side wall has a structure having two parallel panels, respectively inside and outside.
• At least one lower end 26bi of the upper part 26b of the side wall 26 is received with the possibility of sliding between the inner panel and the outer panel for all configurations of the two portions of the drawer between the aligned configuration and the useful tilted configuration of the drawer 10.
• the flank 16 comprises two second lower side panels 265 which are each hinged respectively by a premarketed longitudinal fold line to a lower transverse edge 264 of one of the lower lower side panels.
• the second lower side panels 265 thus extend longitudinally downwards relative to the first longitudinal panels.
• the second lower side panels 265 are folded at 180 ° around the corresponding lower transverse edge 264 to come in parallel and overlap with the lower lower side panels 261.
• This folding of the second Lower side panels 265 could be made inward relative to the lower lower side panels 261.
• these second lower side panels 265 are folded outwardly relative to the lower lower side panels 261.
• the second lower side panels 265 have end edges 266 which, after 180 ° folding of these panels, become upper edges 26as for the lower part 26a of the side walls 26.
• the end edges 266 second lower side panels 265 extend substantially at the same height in the longitudinal direction as the upper edges 263 of the first panels In this case, these two edges 263 and 266 can jointly form the upper edge 26as of the lower portion 26a of the side wall 26.
• an offset could be provided between these two edges, including the longitudinal direction.
• the second lower side panels have a dimension in the longitudinal direction, measured between the lower transverse edge 264 and the end edge 266, which is greater than the longitudinal dimension of the lower portion 180a of the rear panel 180.
• the pre-cut blank 16 intended to form the drawer 10 comprises two lateral flaps 40 each hinged respectively, by a premarketed longitudinal fold line, to one of the two opposite longitudinal edges 200b of the upper part 180b. of the rear panel 180.
• the first lower side panels 261 are separated from the side flaps 40 each corresponding to a cut line, which therefore corresponds to the upper edge 263 of the lower lower side panels 261, and which protrudes longitudinally beyond the level pre-articulated transverse folding line of articulation 360 between the two parts 180a, 180b of the rear panel 180.
• each flap 40 is intended to be folded at 90 ° around the longitudinal edges 200b and to be assembled each, for example by gluing, with the corresponding upper side panel 262 to ensure the three-dimensional formatting of the drawer 10.
• each flap 40 forms, for each side wall 26, an extra thickness delimited downwards by a lower edge, in this case the lower edge of the side flap 40 which corresponds to the upper edge 263 of the first lower side panel 261 belonging to the same side wall.
• the first lower side panel 261 of a side wall is preferably located substantially aligned in the same plane as the corresponding side flap 40.
• the lower edge of the side flap 40 comes, in aligned configuration of the two portions of the drawer, in abutment against the upper edge 263 of the first side panel lower 261 of the lower part 26a of the side wall considered. This stop prevents the upper portion of the spool 10 tilts forward about the transverse axis A1 relative to the lower portion of this drawer.
• the side flaps 40 have free outer longitudinal edges.
• the blank 16 could be constructed with the upper side panels attached not to the transverse upper panel, but to these side flaps, along the outer longitudinal edge.
• the upper side panels would then be oriented, in the blank 16 flat, before the three-dimensional formatting, with their greatest direction in the longitudinal direction.
