Definitions

  • the present invention relates to a packaging box for food product in general and more particularly intended for pastry.
  • the main difficulty to solve in this type of box lies in the fact that it is always necessary to find a good compromise between the transparent surface, consisting of a relatively sheet flexible, and the rest of the box which is made of a material relatively rigid such as cardboard, so that the maximum visualization of the product provided by the transparent sheet does not at the expense of the mechanical strength of the box required during the transport of the contained product.
  • Such a box does not provide any means of reinforcement for compensate for its weakening caused by the creation of windows and does not can find an application only in small volume boxes.
  • Window packaging is also known, described in French patent application No. 2,626,257 which by design, clears a large area of windows. It's about getting by cutting and folding a cardboard sheet, a tubular case in which are arranged the products visible through windows made on three sides extending in length. These windows, even if limited to three sides, offer a good view of the product, but such design significantly weakens said case and requires the availability of reinforcing means which are in the form of cords arranged along the diagonals of the windows, which has the major drawback to hide a central part of the upper window and therefore, the product contained.
  • the object of the present invention is to remedy these various disadvantages to obtain a packaging box offering a visual maximum, while retaining its rigidity qualities. In particular, it must allow observation of the product through these faces side, as from above.
  • the invention relates to a packaging box for food product, in particular pastry, comprising, on the one hand, a container consisting of a polygonal bottom in a first material from which the side walls are drawn perpendicularly, and, on the other hand, a removable cover partially made in said first material of corresponding shape and from which are also from the side walls capable of cooperating in overlap at least partial with those of the container during closing, in order to delimit a reference volume, characterized in that the cover has a central opening covered with a sheet of transparent material flexible, the surface of said opening on the one hand completely covering that of a circle inscribed in said cover, so as to extend to the perpendicular side walls thereof to achieve windows, providing a wider field of vision, and not covering on the other hand, that of a circle in which the said part is inscribed cover, so as to produce corner reinforcements constituted by residual angles of the top of the cover, remaining between the two circles and by adjacent parts of its side walls perpendicular, on either side of the windows.
  • the present invention also relates to the characteristics which will emerge during the description which follows and which should be considered in isolation or in any combination possible techniques.
  • the packaging box 1 designated overall, in Figure 1, is present in the form of a parallelepiped with cross section square.
  • this section can be of any other form polygonal, such as hexagonal or octagonal, or even triangular.
  • the box 1 is made by a parallelepiped, obtained by cutting, from a press made on a cardboard blank, then folded and glued in six points, comprising, on the one hand, a quadrangular bottom portion 3 surrounded by two walls side 4 and 5, a front face 6 and a rear face 7 from the bottom 3 from fold lines a, b, c, d to define container 2 and, on the other hand, a part forming the cover 8 hinging around a upper fold line e of said rear face 7 of container 2 and surrounded by two side walls 9 and 10 and a front face 11 from of said cover 8 from fold lines f, g, h.
  • such a parallelepiped consisting of the container 2 and the cover 8 is obtained from a developed in relatively rigid material, actually a cardboard for food use resistant to both fatty substances and humidity.
  • the hinged cover 8 has a shape corresponding to that of the containing 2, its side walls 9, 10, 11 being able to cooperate in at least partial covering with the walls 4, 5, 6 of the container 2 during of the closure, in order to delimit a reference volume.
  • the cover 8 has a central opening 12 covered a relatively flexible sheet of transparent material 13, the surface of said opening 12 on the one hand completely covering that of a circle A inscribed in said cover 8, so as to extend to perpendicular side walls 9, 10, 11 and 7 thereof to achieve windows 14, 15, 16, 17, offering a wider field of vision, and do not not entirely covering on the other hand that of a circle B in which said cover 8 fits, so as to produce corner reinforcements 18 formed by residual angles 18a from the top of the cover 8, remaining between the two circles A and B and by adjacent parts 18b and 18c of its perpendicular side walls 9, 10, 11 and 7, of on either side of windows 14, 15, 16 and 17.
  • the extensions of the central opening 12 constituting the side windows 14, 15, 16, 17 are at least two in number and produced on at least one of the side faces 7, 9, 10 11, adjacent, so as to delimit between them at least one corner reinforcement 18.
  • these reinforcements 18 are four in number because they relate to a rectangular box with a square section and are made on the two lateral faces 9 and 10 of the cover 8 and on its front 11 and rear 7, so as to determine between them four corner reinforcements 18.
  • the extensions 15 and 17 of the central opening 12 of the cover 8 made on both sides lateral 9 and 10 are formed by circular sectors, while those 14, 16 produced on its rear 7 and front 11 faces are made up of rectangles with rounded angles, both being obtained with the central opening 12 during the same cutting operation.
  • these extensions forming the windows 15, 17 or 14, 16 could all be circular or all rectangular, or any other shape.
  • the residual angles 18a, remaining on the cover 8 after cutting the side windows 14, 15, 16, 17 and of the central opening 12, are delimited by a part of circle 18d, generally in connection with two adjacent windows 14, 17-17, 16-16, 15-15, 14.
  • the side walls 4, 5 and the front face 6 of the part forming the container 2 are provided with cutouts 19, 20, 21 of shape substantially corresponding to the side windows 15, 17, 16 of the cover 8 with which they coincide during the closing of it.
  • the sheet of transparent material relatively flexible 13 covers all of cutouts formed by the central opening 12 of the cover 8 and by its side windows 14, 15, 16, 17 and extends beyond those 6 to be bonded to the relatively rigid remaining parts of said cover 8 and its lateral sides 9, 10, 11, 7.
  • the sheet of flexible transparent material 13 has extensions 22, 23, 24, 25.
  • the sheet of material relatively flexible transparent 13 of the cover 8 is also obtained by cutting.
  • This sheet 13 is advantageously obtained by cutting a polyvinyl chloride.
  • the sheet of transparent material 13 is previously grooved in line with the lines of folding e, f, g, h of the cover 8, thus avoiding any curling of the sheet 13.
  • the sheet of material relatively flexible transparent 13 of the cover 8 has holes ventilation 26 made on the top of the cover 8 and / or on all or parts of its side windows 14, 15, 16, 17, in order to avoid the content-induced condensation.
  • six holes 26 are arranged two by two or three by three on the extensions 22, 23, 24, 25 of the transparent sheet 13 and immediately in front of the circular parts 18d of the residual angles 18a of the corner reinforcements 18.
  • the cardboard bottom 3 of the container 2 receives a metallized gold-colored film 29 providing both the greaseproofness of the background and the promotion of the product.
  • This box is delivered flat and it is instant mounting.
  • closure is carried out by complementary means 27, 28, container 2 and lid 8 respectively, also known as oneself according to the example which has just been described.
  • the packaging box 1 offers a maximum visual of the product on five of its faces and it is thus obtained according to the goal sought by the invention, an excellent compromise between this visual which is maximum and the rigidity of the box which is ensured by its outline and more particularly by the corner reinforcements 18 of the cover 8.
  • the extensions 24 and 25 of the transparent sheet 16, extending to from fold lines e and h, are provided with notches 30 made on said fold lines e and H, on either side of the extensions 24 and 25. These notches 30 extend over these fold lines beyond the central cutout 12 and its lateral extensions 14 and 16 of the cover 8, so as to release the grooved areas.
