Definitions

  • the present invention relates to a foldable packaging provided with an inner lining, as well as to a method for manufacturing such packaging.
  • the flexible inner bag is glued to the narrow foldable closing tabs in triangular zones, the base of which corresponds to the base of the folding closing tab.
  • the flexible inner bag is closed either by winding its open end, or by sealing along a line parallel to the two wide side faces.
  • this sealing along an axis parallel to the two wide lateral faces is essential because the positioning of this line is easier and allows the height of the bag to be reduced.
  • the present invention aims to remedy this drawback by proposing a foldable packaging consisting of a case and a flexible inner bag which can be closed with a satisfactory seal.
  • the present invention relates more particularly to a foldable reclosable package consisting of a rigid or semi-rigid case comprising four lateral faces extended by folding closure tabs and of a flexible inner lining, the open upper part of the lining being glued to the two opposite legs which are wide at certain points at least inscribed inside or in the immediate vicinity of a triangular zone, the base of which corresponds to the line of junction of the closure legs with the corresponding wide side faces.
  • the height of the triangular area is equal to half of its base.
  • the inner lining is sealed along a sealing line parallel to the narrow side faces and passing through the tops of said triangular areas.
  • the cross section of the liner is not necessarily equal to the cross section of the case. In particular, it can be significantly less than the cross section of the case so that the lining is suspended between the two wide side faces, without coming into contact with the narrow side faces, or with only one of them.
  • the ratio of the dimensions of the wide side faces and of the narrow side faces is between 1.3 and 4.
  • the wide side faces are necessarily extended by legs which can be folded down on the reclosable side, while the narrow side faces may not include such folding legs.
  • the liner can be attached to the box by any known means and, in particular, by gluing.
  • the triangular area is on the wide closing tabs and therefore has a large dimension, ensures optimal packaging finish and leads to good shaping of the plies of the flexible lining.
  • the fixing zones on the closure boxes can, of course, be formed by the entire surface of the triangle thus defined or by glue dots arranged substantially at the top of said triangle or by any other arrangement such as a T overturned or parallel bands inscribed inside this triangle.
  • the gluing is done inside the triangle defined above, in an area in the immediate vicinity of the vertex forming a right angle, as well as outside the triangle, in at least two areas arranged on either side.
  • immediate proximity is meant a distance such that the deformation of the material constituting the lining makes it possible to compensate by elastic deformation the offset resulting from the sizing outside the triangular zone.
  • the lining may be formed by a sheath open at both ends or even closed at one end to form a bottom. In the latter case, we will use the more specific term “bag”. In the following description, we will sometimes use the generic term "lining”, sometimes the more specific term “bag”. However, any other type of lining can be envisaged, in particular chemically treated linings in order to resist certain attacks, the choice of material being made according to the future content of the packaging.
  • the lining must protrude sufficiently from the box, so that the open end reaches at least as far as the top of the triangle previously defined and preferably exceeds it.
  • This closure mode can be used for only one end, especially in the case where the lining is constituted by a bag provided with a closed bottom, or at both ends, when the lining is in the form of an open sheath at both ends.
  • the lining can also be glued to the other two side tabs or, on the contrary, not be fixed to these two tabs.
  • the deployment towards the outside of the folding closing tabs on which the lining is glued in a triangular zone causes the two other closing tabs to fold inwards.
  • the foldable packaging comprises a lining constituted by a tubular element, of a cross section substantially identical to the cross section of the box.
  • this embodiment does not make it possible to obtain a packaging that is completely liquid-tight, it makes it possible to produce, at an extremely reduced cost, boxes for the packaging of powders or products to be sheltered from external dust.
  • the constitution of the age fund is done at the time of packaging by folding the closing tabs. To do this, it suffices to fold the closing tabs outwards on which the lining is fixed in a triangular zone, to fold inwards successively one then the other of the two other closing tabs and then to fold towards inside one then the other of the first closing tabs which are then glued to permanently close the bottom of the box. It is then possible to fill the inside of the packaging before closing the other part of the box.
  • one of the closure tabs has at least one projecting part which can cooperate with at least one slot provided on the tab of opposite closure when the two tabs are folded back into the closed position, the lining not being secured to the tab carrying said slot at this slot.
  • the sachet is sealed in its upper part when the packaging is closed.
  • This embodiment makes it possible to constitute a package which can be closed relatively tightly after a first use. Indeed, it is possible, during the first opening, to fold outwards one of the closing tabs provided with a gluing triangle and to cut an end strip passing through the tip of this triangle. This produces an opening through which the contents of the inner lining can flow.
  • the closure tab can constitute a pouring spout.
  • the slot is arranged on the wide lateral face, preferably on the common edge with the corresponding closing tab.
  • This variant has, compared to packages known under the name of "English legged box", the advantage of greater rigidity both when it is open and when it is closed.
  • the packaging according to the present invention on the contrary retains great rigidity thanks to the additional closing tab creating a square profile preventing any deformation of the "belly" type.
  • the slots allow the insertion of the protruding element of the opposite closure tab, so as to temporarily lock the closure tabs in the closed position.
  • These slots can be made parallel to the edge of the closure tab provided with a gluing triangle, so as to cooperate with a tongue extending the end of the opposite closure tab and constituting said projection, or in two angles , so as to cooperate with the corners of the opposite closure tab.
  • the upper closure tab has a rupture line delimiting two zones, the first including at least the largest part of the liner fixing triangle and not being glued to the opposite closure tab and the second substantially complementary zone being glued to the opposite closing tab after the box has been placed in volume.
  • the user tears the upper tab along the rupture line during the first use. He thus has access to the contents of the packaging after he has pierced the sachet, for example by cutting the tip of the partially glued triangle and can close the box thanks to the projecting part which can be inserted in the slot provided on the opposite closing tab.
  • the tightness of the lining is maintained thanks to the double folding of the lining at the upper edges and the locking, in the closed position, of the closing tabs.
  • the box has on at least one of its faces a window, the lining being glued over the major part of the periphery of this window.
  • the window thus makes it possible to view the contents of the packaging, the lining having both a sealing and presentation function.
  • This embodiment makes it possible to produce improved and aesthetic packaging boxes, with a very low manufacturing cost.
  • the bonding on the periphery of the window is not perfect, or if a depression occurs on the window, the sealing of the packaging is preserved.
  • the flexible lining is fixed to a first pair of foldable closing tabs opposite in zones inscribed in a triangle and to the other pair of opposite closing tabs, in at least certain zones inscribed inside or in the immediate vicinity of the vertices of a rectangle one of whose sides corresponds to the junction line of the closure tab with the corresponding face and whose height is substantially equal to half the width of said first opposite closing tabs.
  • the box After filling the lining, the box is closed by folding the two tabs outwardly provided with fixing triangles, which has the effect of folding the two tabs provided with a rectangle in their closed position, perfectly flat with the top of the box, without additional handling.
  • the folds of the lining form automatically perfectly, without requiring manual intervention.
  • the closure of the box is completed by folding in the opposite direction, that is to say inwards, one then the other of the closing tabs provided with a fixing triangle.
  • the box has two opposite faces comprising a central groove perpendicular to the lines of junction of the faces with the folding closing tabs.
  • the packaging Before use, the packaging can be store flat, flattened according to the two central grooves.
  • the setting in volume is carried out simply by exerting a lateral pressure perpendicular to the two central grooves.
  • This embodiment is remarkable in that it prevents the bottom of the lining, when the latter is constituted by a bag having a W-shaped bottom, from twisting during the setting in volume.
  • This twisting should be avoided because it limits the resistance of the bottom of the bag and is not very aesthetic anyway.
  • no solution has been found to avoid this twisting with traditional boxes having only four edges and flattened with respect to two opposite edges of the box.
  • the volume of known type boxes is made by tilting two side faces between a "flat” position where they form an angle of 0 ° with the adjacent side faces to a "volume” position where they form an angle 90 ° with the adjacent side faces, the section being in the "flat” position in the form of a very flat diamond, gradually transforming to a rectangular shape.
  • the bottom of the integral bag with the lateral faces must necessarily adapt to this transformation which induces shearing effects which prevent obtaining a flat bottom when the box is in volume.
  • the twists undergone by the bottom of the bag in particular cause recesses and creases of complex shape and form undesirable cavities.
  • the two opposite faces not provided with a central groove remain face to face and parallel, whether the box is in volume or flat.
  • the bottom of the bag therefore undergoes no shear stress.
  • the two faces provided with a central groove fold symmetrically with this central groove, the initially rectangular section taking a hexagonal shape which becomes more and more flattened as the box is flattened.
  • the W-shaped part makes it possible to compensate for the spacing which occurs on the side of the faces provided with central grooves.
  • a sheath is formed by folding said film back on itself along its median axis. After shaping the lower part of the sheath using a finger creating a W-shaped section, a movable heating blade seals the bottom of the sachet and cuts the sachet from the rest of the film.
  • the packaging formed according to this variant can be very easily laid flat or in volume and its use on a packaging machine of known type poses no difficulty.
  • the upper wide tab is of a dimension substantially corresponding to the cross section of the box. It has a breaking line formed by a segment, substantially parallel to the main edge and passing through the gluing triangle, connected to the upper edge of the upper wide tab by two curved sections, said breaking line delimiting a tear-away part.
  • the large opposite closing tab consists of two parts that are substantially symmetrical with respect to a breakable median fold line.
  • the shape of these symmetrical parts corresponds substantially to the shape of the tear-off tab.
  • the large upper tab is glued along the lateral edges, its tear-off part being glued at least partially on the external symmetrical part of the large lower tab.
  • the lining is glued on only one of the wide legs, as defined above.
  • the lining is glued to the other opposite wide tab, in any zones which may be outside the triangular zone defined above.
  • This last wide tab has folding grooves corresponding to the two sides of the previously defined virtual triangular area. Its depth is at most equal to the height of the triangular zone.
  • the tab provided with folding grooves is then folded inward first and is covered by the other closing tabs in order to maintain a satisfactory aesthetic appearance.
  • the present invention also relates to a device for packaging a product in such a packaging comprising means for sealing the open end of the inner lining along a line passing through the vertices of the triangles when the wide closure tabs are folded out.
  • the foldable packaging according to the present invention as shown in Figure 1 consists of a box (1) and a flexible bag (2).
  • the flexible bag (2) has, in the example described, an open upper end and a closed lower end.
  • plastic material of the polyethylene or polypropylene type. It can also be made of any other flexible material, such as paper, aluminum, aluminized plastic. The choice of material is made according to the physicochemical characteristics sought: air, dust, gas tightness, resistance to chemical agents.
  • the bag (2) is a bellows bag made from a flexible sheath usually delivered on a reel, cut using a hot cutting blade, the sides of which are sealed after the bellows have been formed by folding the film on himself.
  • a sachet is thus obtained with the desired dimensions, that is to say the section of which corresponds, in the example described, substantially to the section of the box (1) in shape and the height of which corresponds, in the example described , substantially the sum of the height of a lateral face (5) of the box (1) and the height of a closure tab (9) increased by a length roughly equal to one tenth of the height of the box.
  • the box (1) is advantageously made of cardboard, in particular micro-corrugated cardboard or solid cardboard. It may have openings, such as windows, possibly covered with a rigid or semi-rigid transparent sheet.
  • One of wide side faces (6) has a connection tab (10) corresponding to a bonding and connection area (14), located on the opposite side face (8).
  • the side faces (5, 6, 7, 8) have foldable closing lugs, respectively (9, 10, 11, 12) at their upper end.
  • the wide side faces (6, 8) are provided with large upper legs, respectively (10, 12) while the narrow side faces (5, 7) are provided with small upper legs, respectively (9, 11).
  • one of the large upper legs (10) intended to be folded down before the opposite large upper leg (12) has a dimension slightly greater than the latter so as to allow easy folding of the second large upper leg (12). .
  • the large tabs (10, 12) have gluing zones inscribed in or near virtual isosceles triangles (24, 26).
  • the first gluing zone (100, 200) is located inside the triangle (24, 26) near the upper vertex (101, 201) forming an angle of 90 °.
  • the two other gluing zones (102, 202) and (103, 203) are arranged below the base (104, 204) of said triangle (24, 26), at the ends of a virtual line segment (105, 205) parallel to said base.
  • the spacing between the base (104) and the segment (105) is very small, of the order of a few millimeters at most.
  • the geometry of the glued surfaces can, of course, differ from the example described without departing from the scope of the invention. They can in particular be produced in the form of an inverted "T" inscribed between the three previously defined zones, or else by gluing the entire surface of the virtual triangle.
  • the bag is also glued, in the example described, on the small tabs (9, 11) in certain areas inscribed inside a virtual rectangle (106, 206). These areas (107 110), (207 to 210) are for example arranged at the four corners of said rectangle.
  • the bag is glued to the side faces by strips of glue (301 to 305) arranged axially in such a way so that the inside surface of the box is glued along only one side of each of the edges (306 to 308).

  • the closing tabs (10, 12) By folding the closing tabs (10, 12) outwards, in the direction indicated by the arrows F ′, the closing tabs (9, 11) are folded inwards along the direction of the arrows F ' .
  • This movement is caused by the tension resulting from the gluing of the lining on the upper legs (9 to 12) of the box.
  • the part of the bag extending beyond the top of the triangles (24, 26) forms two parallel lips (35, 36) which can be rolled up and folded down over the top of the box before closing the two folding tabs (10, 12) or even be sealed by hot irons. If these two lips (35, 36) are sealed, a closure which is practically impermeable to liquids and gases is obtained.
  • the cardboard blank further comprises two grooves (20, 21) extending along the median axis of the large lateral faces, respectively (6, 8), thus than on the large closing tabs, respectively (10, 16) and (12, 18) which extend them.
  • These two central grooves (20, 21) make it possible to give the box, before the closing tabs (9 to 12) and (15 to 18) folded down, a substantially hexagonal section, or even to flatten it completely on both sides. of a plane passing through the two grooves (20, 21).
  • the grooves (20, 21) are positioned substantially in the plane formed by the two corresponding large side faces (6, 8) and are stiffened by the fact that the folding of the upper legs prevents the folding of the lateral faces.
