Abstract

The package has a case (10) and an insert (20) for rigidifying the case. The insert is placed inside the case. The case has a least resistance line that divides the case into an upper part that is susceptible to be torn and a lower part that presents products, after the upper part is torn. The case and the insert are made from same cardboard blank. The package is formed by folding the blank.

Description

The invention generally relates to cardboard packaging of

  packaging and exposure of products.

  More specifically, the invention relates to a carton packaging and exposure of products, comprising a box and a stiffening insert of the body, the box comprising a line of weakness dividing the box into a top portion likely to be torn off and a lower part able to serve as a display products.

  Packages of this type are known from the prior art, and comprise a box made of a relatively weaker first cardboard blank, and an insert cut from a second, relatively stronger cardboard blank, placed in the box and fixed in the box. by points of glue or by other means.

  These packages have the advantage that one can use a lightweight and inexpensive carton to achieve the box, without compromising the strength of the package. On the other hand, a large quantity of cardboard is necessary to make a package of this type.

  In this context, the present invention aims to overcome the defect mentioned above and to provide an economical package, requiring the use of a smaller amount of cardboard.

  To this end, the device of the invention, moreover in accordance with the generic definition given in the preamble above, is essentially characterized in that the box and the insert are made of material in the same blank of cardboard .

  In a possible embodiment of the invention, the package is formed by folding the blank, without detaching the parts of this blank intended to form the box and the insert.

  Advantageously, the blank comprises a plurality of longitudinally aligned sections separated by first mutually parallel fold lines, and at least one upper flap extending transversely from a panel, the panels forming after folding the sides of the box and the upper flap a lid of the crate.

  Preferably, the blank comprises at least one reinforcing flap extending transversely in the extension of a panel and connected thereto by a second fold line, this reinforcing flap forming the insert or a part of the insert after folding.

  For example, the reinforcing flap extends on the same transverse side of the panels as the upper flap.

  According to another characteristic of the invention, the blank comprises a plurality of reinforcing flaps extending transversely in the extension of each of the panels with the exception of the pan from which the upper flap extends.

  In a first variant, the reinforcing flaps are all connected to the panels by second folding lines.

  In a second variant, first reinforcing flaps are connected to the panels by longitudinal second fold lines, at least one last reinforcement flap being connected to a first neighboring reinforcing flap by a transverse fold line.

  Preferably, or the reinforcing flaps after folding extend against the sides of the body.

  Finally, the blank comprises lower flaps extending transversely from the sides of a side opposite to the upper flap, these lower flaps forming after folding a bottom of the body.

  Other features and advantages of the invention will emerge clearly from the description which is given below, by way of indication and in no way limiting, with reference to the appended figures, among which: FIG. 1 is a plan view of the blank used to constitute the packaging of the invention, - Figure 2 is a top view of the blank of Figure 1 after bonding, - Figures 3 to 6 are perspective views of the successive steps of folding the blank of the figure 2 to form the package, - Figures 7 and 8 are perspective views showing tearing of the top of the box to form a display of the products, and - Figure 9 is a perspective view showing the package. after removal of the products and resetting.

  The invention relates to a cardboard packaging intended both for the packaging of products for transport, as shown in FIG. 6, and for the exposure of these products, as shown in FIG. 8, in particular in supermarket shelves. .

  The package comprises a box 10 and a stiffening insert 20 of the box 10 disposed inside this box 10, so that the packaging has a substantial intrinsic strength, and is suitable for packaging non-rigid products such as, for example, cheese chips or small items stored loose in the package.

  The box 10 is typically parallelepipedal, and comprises four sides 14, a cover 15, and a bottom 16.

  Two adjacent sides 14 are mutually perpendicular, the cover 14 and the bottom 15 being mutually parallel and extending in planes perpendicular to the sides 14.

  The box 10 comprises a line of least resistance 11 dividing the box into an upper part 12 that can be torn off and a lower part 13 able to serve as a display products after tearing of the upper part 12.

  This line of least resistance 11 is closed contour, and typically extends through the four sides 14, so that the lower portion 13 after tearing of the upper portion 12 consists of the bottom 16 and a lower band 14. The upper part 12 comprises the cover 15 and an upper band of the sides 14.

  The line of weakness 11 may also extend along other contours, and for example cross only three of the four sides 14 and the cover 15. The precise contour of this line 11 is determined according to the shape of the products, so as to make them easily grasped in the display once the upper part 12 of the box 10 torn off.

  The line of weakness 11 is typically made by precutting the cardboard on evenly spaced segments along said line. Three orifices 111 in half-moons are cut in the box 10, each on a different face 14, and arranged so that the line of weakness 11 follow the right edge of each of the orifices 111.

  According to the invention, the box 10 and the insert 20 are made of material in the same blank 30 of cardboard, shown in FIG.

  The package, that is to say the box 10 and the insert 20, is formed by folding the blank 30 and sticking this blank at certain points which will be specified later, without mutual separation of the parts of this blank. intended to form the box 10 and the insert 20.

  As seen in Figure 1, the blank 30 comprises four sections 31 aligned longitudinally and separated by first mutually parallel transverse fold lines 32. The longitudinal direction is horizontal in Figure 1. The sections 31 are rectangles of the same transverse width. The first and third panels 31 starting from the left of FIG. 1 are of the same relatively smaller longitudinal length, and the second and fourth panels 31 starting from the left of FIG. 1 have the same relatively longer longitudinal length.

  The fourth section 31 carries a transverse free edge a gluing tab 311 projecting outwards.

  The blank 30 also comprises an upper flap 33 extending transversely from a longitudinal side of the fourth panel 31. The upper flap 33 is separated from the fourth panel 31 by a longitudinal fold line corresponding to the edge of said panel 31.

  This upper flap has a rectangular shape and extends over the entire longitudinal length of the fourth section 31. It comprises a rectangular main portion 331 connected to the fourth section 31 and a longitudinal strip 332 extending transversely to the main portion 331 on a side opposite to fourth pan 31. The longitudinal band 332 is separated from the main part by a longitudinal fold line, and thus constitutes a flap.

  The main portion 331 has a transverse width substantially equal to the longitudinal length of the first and third panels 31, and the longitudinal band 332 has a small transverse width relative to that of the transverse portion.

  After forming the blank 30, the panels 31 form the sides 14 of the box 10 and the upper flap 33 the lid 15 of the box 10.

  The blank 30 further comprises four lower flaps 38 extending transversely each from one of the panels 31, a transverse side of the panels 31 opposite the upper flap 33, these lower flaps 38 forming after folding the bottom 16 of the body 10.

  The lower flaps 38 are separated from the panels 31 by third longitudinal fold lines 39 corresponding to longitudinal edges of the panels 31.

  In the embodiment shown in Figures 1 to 9, the bottom 16 is of automatic type. The lower flaps 38 consequently each have a trapezoid shape whose large base is constituted by the third fold line 39. These lower flaps 38 have two oblique edges converging towards each other as far as the small base, which constitutes a substantially longitudinal free edge parallel to and opposite to the third fold line 39.

  The lower flaps 38 connected to the second and fourth panels 31 each bear on an oblique edge a glue tab 381, separated from the lower flap 38 by a fold line corresponding to the oblique edge.

  The blank 30 also comprises at least one reinforcing flap 34 extending transversely in the extension of a panel 31 and connected thereto by a second longitudinal fold line corresponding to a longitudinal edge of said panel 31, this flap of reinforcement 34 forming the insert 20 or part of the insert 20 after folding.

  This reinforcing flap 34 extends on the same transverse side of the panels 31 as the upper flap 33.

  In a preferred embodiment shown in Figures 1 to 9, the blank 30 comprises three reinforcing flaps 34 extending transversely in the extension of each of the panels 31 with the exception of the pan 31 from which the flap extends. upper 33, that is to say extending in the transverse extension of the three leftmost pans 31 of Figure 1.

  These reinforcing flaps 34 have substantially rectangular shapes, of the same width transversely as the panels 31, and each extend substantially over the entire longitudinal length of the corresponding pan 31.

  According to a first variant embodiment, not shown, the reinforcing flaps 34 are all connected to the panels 31 by second longitudinal fold lines 35 corresponding to longitudinal edges of the panels 31.

  The reinforcing flaps 34 are then all independent of each other, that is to say that each flap 34 is linked only to the corresponding pan 31 and no other reinforcement flap.

  According to a second variant embodiment, represented in FIGS. 1 to 9, two first reinforcing flaps 34 are connected to two flaps 31 by second longitudinal fold lines 35, a last reinforcement flap 36 being connected to a first reinforcing flap 34 immediately adjacent by a transverse fold line 37.

  The first two reinforcing flaps 34 are connected to the first and third faces starting from the left of FIG.

  The last reinforcing flap 36 is in the transverse extension of the second panel 31 starting from the left of FIG. 1, and it is connected to the first reinforcement flap 34 located in the transverse extension of the third panel 31, starting from the left of FIG. 1. This last flap 36 is not linked directly to one of the panels 31.

  We will now describe in detail the sequence for constituting the package from the blank 30, with reference to Figures 2 to 6, and the tearing sequence of the upper part of the box 20 to form the display, with reference in Figures 7 and 8, for a package according to the second embodiment described above.

  The packaging is first glued. The gluing tab 311 is glued to the transverse free edge of the first panel 31 from the left of FIG. 1. The gluing tabs 381 are also glued to the lower flaps 38 located opposite these tabs, and the lower flaps are folded towards the inside of the package. The packaging is kept flat, in the state shown in Figure 2. It will be noted that the packaging manufacturers deliver them in this state to the entity responsible for packaging the products in the package.

  The packaging is then shaped.

  As seen in Figure 3, first is the bottom 16 by nesting the lower flaps 38 with each other. For this purpose, at least the two lower flaps 38 carrying the gluing tabs 381 have small bases cut in such a way as to be mutually locked, these cuts being able to present multiple forms known in themselves which will not be described here. The lower flaps 38 are interlocked with each other by folding them in a plane substantially perpendicular to the panels 31, and by placing the panels 31 in their parallelepipedal final configuration.

  Then, as shown in FIG. 4, the first reinforcing flap 34 and the last reinforcement flap 36 are folded towards the inside of the package 10 and the last reinforcing flap 36 is folded perpendicularly to the first reinforcing flap. 34, and these plates are plate against the inner faces of two contiguous sides 14 of the box 10.

  The other first reinforcing flap 34 is then folded towards the inside of the package 10, as in FIG. 5, until it is pressed onto an inner face of the corresponding side 14.

  The products to be packaged can then be placed in the package 10 and the upper flap 33 folded to close the package, as shown in FIG.

  The longitudinal band 332 is previously folded perpendicularly to the main part 331 of the upper flap 33, so that this strip is inserted between the last reinforcement flap 36 and the side 14 against which this flap 36 is pressed when the main part 331 of the upper flap 33 is placed in a plane perpendicular to the sides 14.

  The package 10 is then in its proper configuration for transporting the products.

  It is necessary to tear the upper portion 12 of the package 10 along the line of weakness 11 when it is desired to expose previously packaged products.

  Note that the package 10 typically has three orifices 111, one on each of the sides 14 corresponding to the first three panels 31 from the left of Figure 1.

  To tear the upper part 12, a user introduces a finger in the orifice 111 of the second panel 31 and urges the portion of the side 14 located above the line of weakness 11 towards the outside of the package 10, to tear the side 14 along said line.

  It then does the same for the orifices 111 located on the other two sides 14 of the box 10. The upper part 12 of the box 10 is then substantially completely detached from the lower part 13, the user if necessary pulling the upper part 12 to tear it away completely.

  As seen in Figure 8, the insert 20, consisting of the reinforcing flaps 34 and 36, comes with the upper part 12 of the box.

  Once all the products removed from the lower part 13, it is possible to remount this lower part 13, and the upper part 12 attached to the insert 20, as seen in Figure 9.

  The packaging described above may have multiple variants without departing from the scope of the invention. Thus, the package may not be parallelepiped and have less than or more than four sides 14. The blank 30 will then include as many reinforcement flaps 34 as side 14, minus one.

  The bottom 16 may be not automatic type but semiautomatic type or American box type. The semiautomatic bottoms consist of four components linked by nesting with each other without gluing. Cash funds type US are made up of four rectangular shutters, the two components linked to the short sides of the box being folded first, the two components linked to the long sides of the box being folded under the first two panels and glued to those -this.

  Tab 311 and tabs 381 may not be adhered but may be secured by other means, for example staples.

  The insert 20 may consist of a number of reinforcement flap different from three, depending on the desired rigidity for the package. These flaps are preferably connected to the same side of the panels as the upper flap, but one or more reinforcing flaps can also be connected to the opposite transverse side, instead of one or more lower flaps, provided that it is possible to constitute a sufficiently resistant bottom with the number of lower flaps remaining.

  It is understood that the package described above has multiple advantages.

  As the insert is made in the same cardboard blank as the case, the falls are reduced to a minimum. The cost of packaging is thus reduced, as is the amount of waste, which is favorable from an environmental point of view.

  The shaping of the package is easy because it is done simply by folding, with a small number of gluing points.

  It is possible to do this formatting manually, the packaging can thus be used for small series.

  The packaging is usable both for the transportation of products and their exposure in the shelves of supermarkets. We move from the transport configuration to the exposure configuration of the packaging very easily, by simply pulling along a line of least resistance.

  This pulling does not require the use of a cutter, which reduces the risk of injury to personnel, and also reduces the risk of food packaging being pierced by the cutter blade, resulting in potential contamination of the cutter blade. these products.

  The packaging, when put in waste after use, consists of only two pieces, which avoids the dispersion of small pieces of cardboard.

  The packaging consists only of cardboard, without any plastic or metal parts, which makes recycling easier by material recovery or incineration.

  Finally, the strength of such a package is very satisfactory, and can be tailored to the products.
