Description

Information support display and associated manufacturing method

[0001] The present invention relates to the field of information support displays for communication or visual advertising at points of sale known by their acronym PLV.

[0002] As is commonly known, an information support display (hereinafter "display") is a column that folds back on itself and unfolds automatically. It has the advantage of being able to be transported and stored in excellent conditions and to be installed very quickly on site.

[0003] By way of example, with reference to the, a display stand 100 comprises a first presentation wall 101, a second presentation wall 102, holding inserts 103, mounted between the first presentation wall 101 and the second presentation wall 102, and elastic bands 104 connecting the holding inserts 103 to the first presentation wall 101 and to the second presentation wall 102 to maintain the presentation walls 101, 102 in the curved state. The display stand 100 comprises folding lines L1, L2, L3 in order to be able to store the display stand 100 with a small footprint. Such a display stand 100 is known for example from patents FR2824946A1 and FR2876828A1.

[0004] As illustrated in the, the display stand 100 is generally produced by assembling the presentation walls 101, 102 with the holding inserts 103 and the elastic bands 104, the elastic bands 104 connecting the holding inserts 103 to the mounting edges of the presentation walls 101, 102.

[0005] In practice, each display wall 101, 102 is made of cardboard having a weight of around 350g / m2 while the holding inserts 103 are made of a cardboard comprising flutes known by its English name “flute”, for example comprising a corrugated sheet of cardboard glued to two flat sheets of cardboard. The holding inserts 103 thus have greater stiffness. Such a display 100 is for example known on the websites http: / / www.lovinoo.com / product / show / id / 173.html and http: / / www.bushorchimp.com / pz51d1705-cz5972485-pop-up-lama-display-custom-cardboard-standee-for-electronic-cigarette.html. Such holding inserts 103 have a high cost and require the use of glue during their manufacture, which increases its environmental impact.

[0006] The elastics 104 exert a tensile force along the axis of the holding insert 103, that is to say, along a compression line LC which extends horizontally as illustrated in the. The use of a holding insert 103 of high stiffness makes it possible to take up the horizontal compression forces which are applied to the mounting edges of the display walls 101, 102 in order to prevent the latter from deforming. In the event of a significant compression force, the holding insert 103 is likely to suddenly give way by buckling leading to sudden folding of the display walls 101, 102. The display stand 100 can then no longer be used, which presents a disadvantage.

[0007] Furthermore, with reference to the, in order to allow the attachment of an elastic band 104 to a holding insert 103, each holding insert 103 comprises two through openings 105 in which extends, for each, a projecting finger 106. An insertion distance K3 is subsequently defined, in the horizontal direction, between the end of a projecting finger 106 and the edge of the through opening 105 in which it extends.

[0008] When assembling the display stand 100, the operator must pull the elastic band 104 to pass it around the protruding finger 106. To achieve this goal, the through opening 105 must be wide enough to allow the operator's fingers to pass through. In other words, the insertion distance K3 must be large enough and it is necessary to form sufficiently wide through openings 105. The presence of large through openings 105 weakens the holding insert 103, in particular, in the horizontal direction in which the forces must be taken up. The greater the insertion distance K3, the lower the mechanical strength along the compression line LC.

[0009] The invention thus aims to eliminate at least some of these drawbacks.

[0010] In the prior art, patent application WO2014 / 024834A1 discloses an information support display having two presentation faces held by a screwed holding plate. Applications EP2650862B1 and US7159350B2 teach cardboard information supports. PRESENTATION OF THE INVENTION

[0011] The invention relates to an information support display comprising:At least one first presentation wall, at least one second presentation wall, each presentation wall comprising a first mounting edge and a second mounting edge, each presentation wall being made from a sheet of cardstock having a first weight,At least one retaining insert mounted between the first presentation wall and the second presentation wall anda plurality of constraining members configured to connect the first mounting edges and the second mounting edges to the retaining insert so as to bulge the presentation walls,

[0012] The invention is remarkable in that the holding insert is made from a sheet of cardboard paper having a second weight, the difference in weight between the first weight and the second weight being less than 50g / m2.

[0013] Thanks to the invention, the display walls and the holding inserts can be made of similar materials, which facilitates logistics. It is no longer necessary to use corrugated cardboard with higher stiffness as in the prior art. Thanks to the flexibility of the holding insert according to the invention, the mounting of the stressing members is facilitated and the display can be deformed elastically, which prevents any damage. Indeed, in the event of high compressive force, the holding insert bends due to its flexibility. The buckling is progressive and fulfills a damping role.

[0014] Furthermore, from an environmental perspective, offcuts from display walls can be advantageously used to form support inserts. Thanks to the invention, the manufacture of a display is "greener".

[0015] Preferably, the first weight is less than or equal to 555g / m2, preferably equal to 350g / m2. Such cardboard is flexible and can be conveniently recycled since it is glue-free. Preferably, the first weight is identical to the second weight. Using the same material facilitates logistics and reduces costs.

[0016] Preferably, the display comprising several holding inserts, each holding insert comprises: a first end configured to be connected to the first mounting edges of the display walls by at least one first constraint member, a second end configured to be connected to the second mounting edges of the display walls by at least one second constraint member so as to bulge the display walls.

[0017] The use of several discreetly distributed support inserts reduces the amount of material used and makes folding / unfolding the display easier.

[0018] Preferably, at least one holding insert is printed, preferably from a sheet of cardboard from a printing test of at least one presentation wall. This makes it possible to reduce the ecological impact of such a holding insert by using printing waste. Preferably, at least one holding insert is laminated.

[0019] According to one aspect of the invention, at least one holding insert has a length of between 400mm and 420mm, preferably between 405mm and 415mm.

[0020] Preferably, at least one holding insert has a height between 160mm and 190mm, preferably between 160mm and 170mm.

[0021] According to one aspect of the invention, at least one holding insert extends in an insert plane and comprises at least one projecting finger configured to cooperate with a constraint member. The projecting finger is manually tiltable by an angle of inclination of at least 10° relative to the insert plane. Thus, the projecting finger makes it possible to form a protrusion / hook, which facilitates the mounting of a constraint member by an operator.

[0022] Preferably, the retaining insert comprises a through opening in which the projecting finger is mounted, an insertion distance being defined between the end of the projecting finger and an edge of the through opening, the insertion distance being between 10mm and 55mm. A reduced insertion distance makes it possible to increase the cardboard material along the compression line to increase the mechanical strength of the retaining insert.

[0023] Preferably, at least one retaining insert has at least one straight side edge, preferably two straight side edges. Such a retaining insert makes it possible to maximize the material in an insert to increase mechanical strength. Preferably, the retaining insert has a rectangular shape.

[0024] Preferably, each constraint member is in the form of an elastic loop.

[0025] Preferably, each holding insert has a thickness of less than 440 μm. This advantageously makes it possible to limit the thickness of a display in the folded state by more than one centimeter depending on the number of folding lines. This advantageously makes it possible to store a greater number of displays in the same container, which is very advantageous.

[0026] The invention also relates to a method for manufacturing a display, as presented above, comprising steps consisting of:Printing, by means of a printing machine, at least one first display wall on at least one test sheet so as to adjust the printing machine, each test sheet being made of cardboard paper having a first grammage,Printing, by means of the printing machine after adjustment, at least one first display wall and at least one second display wall on at least one production sheet, the production sheet being made of the same cardboard paper as the test sheet,Cutting the first display wall and the second display wall from the production sheet(s),Cutting the holding inserts from the test sheet andAssembling the first display wall,the second display wall and the holding inserts with a plurality of constraining members in order to form the display.,

[0027] Advantageously, the present invention makes it possible to improve the manufacture of a display by making it possible to use printing waste by recycling it in an ingenious manner. PRESENTATION OF FIGURES

[0040] With reference to the, there is shown an information display P comprising two presentation walls 1, 2 but the invention also applies to an information display P comprising more than two presentation walls 1, 2, in particular, 3 or 4.

[0041] Preferably, each display wall 1, 2 has a width of between 400mm and 650mm. Preferably, each display wall 1, 2 has a height of between 1300mm and 1900mm.

[0042] As illustrated in Figures 5 and 6, each display wall 1, 2 has a first mounting edge 11, 21 and a second mounting edge 12, 22. The mounting edges 11, 12, 21, 22 of a display wall 1, 2 are diametrically opposed and are in the form of tabs or flaps. In this example, the display walls 1, 2 are independent but it goes without saying that they could be made by folding a single sheet of paper.

[0043] The first mounting edges 11, 21 are intended to be assembled together. Similarly, the second mounting edges 12, 22 are intended to be assembled together. Such mounting edges 11, 12, 21, 22 are known to those skilled in the art and will not be presented in detail. They allow in particular the mounting of constraint members as will be presented subsequently.

[0044] In a known manner, each presentation wall 1, 2 is made from a sheet of cardboard paper having a first weight G1 less than or equal to 555g / m2. Preferably, the first weight G1 is between 300g / m2 and 400g / m2, more preferably equal to 350g / m2. Such cardboard paper is readily available and can be advantageously recycled since it is free of glue.

[0045] Each display wall 1, 2 is preferably printed with the information to be presented. Preferably, each display wall 1, 2 is also laminated so as to protect the printing and increase the lifespan of the display P, in particular, under the effect of external conditions.

[0046] In this example, each display wall 1, 2 has a central portion between the two mounting edges 11, 12, 21, 22. The central portion has a width F1, defined in a horizontal direction, which is between 480mm and 520mm, preferably between 490mm and 510mm. Each display wall 1, 2 also has folding lines L1, L2, L3 to allow folding in four according to the height. The number of folding lines is generally between 2 and 6.

[0047] According to the invention, with reference to figures 4 and 6, the display stand P comprises a plurality of holding inserts 3 mounted between the first presentation wall 1 and the second presentation wall 2 and a plurality of constraint members 4 configured to connect the mounting edges 11, 12, 21, 22 of the presentation walls 1, 2 to the holding inserts 3 so as to bulge the presentation walls 1, 2.

[0048] Preferably, the holding inserts 3 are distributed discreetly in the display P, in particular, distinct and vertically offset. This makes it possible to fold the display P without folding the holding inserts 3 which are positioned between the folding lines L, L2, L3. This makes it possible to limit the quantity of cardboard used to form the holding inserts 3 while increasing the operability (folding / unfolding of the display P), which increases its lifespan. The invention also applies to a single holding insert 3, in particular, a holding insert 3 extending over more than 50% of the height of the display P.

[0049] In this example, the constraint members 4 are in the form of elastic loops, in particular, an elastic of the 120mmx5mm type. It goes without saying that circumferences between 100 and 150mm could be suitable. Likewise, it goes without saying that widths between 2 and 8mm could be suitable.

[0050] As illustrated in Figures 4 and 6, each holding insert 3 is connected to the mounting edges by two constraining members 4. With reference to the, each holding insert 3 comprises: a first end 31 configured to be connected to the first mounting edges 11, 21 of the presentation walls 1, 2 by a first constraining member 4, a second end 32 configured to be connected to the second mounting edges 12, 22 of the presentation walls 1, 2 by a second constraining member 4.

[0051] It goes without saying that a single holding insert 3 could be connected to the mounting edges by a single constraint member 4 which would connect the first mounting edges 11, 21 to the second mounting edges 12, 22 of the presentation walls 1, 2. In such a variant, the constraint member 4 is in the form of an elastic wire, preferably with locking elements at its ends, for example rigid bars (metallic, plastic or other) or a knot.

[0052] The association of a holding insert 3 with one or more constraining members 4 makes it possible to form a device for assembling the display P which is known to those skilled in the art. This assembly device is configured to exert a tensile force along the axis of the holding insert 3, that is to say, along a compression line LC which extends horizontally as illustrated in.

[0053] According to the invention, each holding insert 3 is made from a sheet of cardboard having a second weight G2. The difference in weight between the first weight G1 and the second weight G2 is less than 50g / m2.

[0054] Preferably, the second weight G2 is between 300g / m2 and 400g / m2, more preferably equal to 350g / m2. More preferably, the first weight G1 and the second weight G2 are equal.

[0055] Thus, thanks to the invention, it is possible to form a holding insert 3 in a material similar to that of the display walls 1, 2, which facilitates logistics. Only one material is necessary to form the display P. This advantageously goes against the prejudices of the prior art which required that a holding insert 3 be made in a very rigid material different from the display walls 1, 2.

[0056] The use of a less stiff and more flexible holding insert 3 has several advantages. For example, when significant horizontal compressive forces are applied to the mounting edges of the display walls 1, 2, the holding inserts 3 gradually deform elastically, without yielding abruptly. As a result, the display P returns to its original shape when the horizontal compressive forces are no longer applied. The display P is not damaged.

[0057] Preferably, at least one holding insert 3 is printed. It preferably comes from a sheet of cardboard paper from a test printing of at least one presentation wall 1, 2. Indeed, as illustrated in the, during serial printing of the presentation walls 1, 2 by means of a printing machine 10, it is necessary to calibrate the printing machine 10 by carrying out several test prints of the presentation walls on FT test sheets. This is particularly the case for overlay printing (offset). Thus, the holding inserts 3 are cut from the FT test sheets comprising presentation wall prints 1, 2. The holding inserts 3 are thus made from materials which were previously discarded and considered unsuitable for forming holding inserts 3. The planet's resources are preserved and logistical constraints are reduced.

[0058] The use of printed holding inserts 3 does not present any disadvantage for the final use since the holding inserts 3 remain hidden in the use position of the display P.

[0059] According to a preferred aspect, at least one holding insert 3 is laminated. When lamination tests are carried out on a printed sheet, these sheets can be advantageously used to form holding inserts 3, the lamination further reinforcing the mechanical strength of a holding insert 3.

[0060] In order to allow optimal support while being made from a material having a lower stiffness than in the prior art, it is proposed to modify the characteristics of the support inserts 3.

[0061] With reference to the, each holding insert 3 has a length F3 of between 400mm and 420mm, preferably between 405mm and 415mm. Similarly, each holding insert 3 has a height H3 of between 160mm and 190mm, preferably between 160mm and 170mm. Such dimensions make it possible to maximize the material used in a test sheet, which limits losses.

[0062] Preferably, each holding insert 3 has a thickness of less than 440 μm. This advantageously makes it possible to limit the thickness of a display P in the folded state by more than one centimeter depending on the number of folding lines. This advantageously makes it possible to store, in the same container, a greater number of displays P, which is very advantageous.

[0063] According to a preferred aspect of the invention, the holding insert 3 has at least one lateral edge 33, 34 which is rectilinear. The lateral edge 33, 34 is intended to come into abutment with the presentation walls 1, 2, in particular, in a fold line of the mounting edge. A rectilinear lateral edge 33, 34 makes it possible to improve stability while increasing stiffness along the compression line LC by providing more material compared to the prior art in which the lateral edges were concave. Preferably, the holding insert 3 has a rectangular shape, which facilitates cutting and makes it possible to optimize the transmission of forces along the compression line LC.

[0064] In this example, with reference to the, in order to allow the attachment of the constraint members 4 having a loop shape to a holding insert 3, each holding insert 3 comprises a first through opening 5 comprising a first projecting finger 6 and a second through opening 5 comprising a second projecting finger 6. An insertion distance d3 is subsequently defined, in the horizontal direction, between the end of a projecting finger 6 and the edge of the through opening 5 in which it extends.

[0065] Since the holding insert 3 is made of a material having a lower stiffness, the insertion distance d3 can be significantly reduced without affecting the assembly. Indeed, as illustrated in, due to the flexibility of the material, the projecting finger 6 can be manually inclined by an angle of inclination α to extend out of a plane P3 in which the holding insert 3 extends. This allows an operator to mount the constraint member 4 to the projecting finger 6 in a convenient manner, independently of the insertion distance d3. The projecting finger 6 advantageously forms a hook to which the constraint member 4 can be hooked.

[0066] With reference to the, several forms of through openings 5, 5' are presented. An insertion distance d3, between 10mm and 55mm, makes it possible to retain a significant quantity of material along the compression line LC, which improves the mechanical strength of the holding insert 3. Due to the inclination of the projecting finger 6, a small insertion distance d3 does not present any disadvantage for an operator. According to another aspect, the projecting finger 6 is formed by cutting the material without forming a through opening and removing a cut surface (without peeling).

[0067] Preferably, each projecting finger 6 is tiltable by at least 10° relative to the plane P3. Advantageously, the projecting finger 6 is tiltable in one direction or another. Preferably, the projecting finger 6 is elastic and aligns naturally in the plane P3 after tilting.

[0068] An example of implementation of a method for manufacturing a display P according to the invention will now be presented. With reference to the, the manufacturing method comprises steps consisting of:Printing E1, by means of an offset printing machine 10, at least one first presentation wall P1 on at least one test sheet FT so as to adjust the printing machine 10, each test sheet FT being made of cardboard paper having a first grammage,Printing E2, by means of the printing machine 10 after adjustment, at least one first presentation wall P1 and at least one second presentation wall P2 on at least one production sheet FP, the production sheet FP being made of the same cardboard paper as the test sheet FT,Cutting E3 the first presentation wall 1 and the second presentation wall 2 from the production sheet(s) FP,Cutting E4 the holding inserts 3 from the test sheet FT,andAssembling E5 the first display wall 1, the second display wall 2 and the holding inserts 3 with a plurality of constraining members 4 in order to form a display P as illustrated in.,

[0069] The presentation walls 1, 2 and the holding inserts 3 are thus formed from a material having the same weight.

[0070] The process steps have been presented in an order given as an example. It goes without saying that the steps could be carried out in a different order.

[0071] Optionally, the method comprises a step of laminating the FT test sheets and / or the FP production sheets.

[0072] Thanks to the present invention, it is no longer necessary to use a high-stiffness material (which is expensive and harmful to the environment) to form holding inserts 3. Advantageously, a holding insert 3 in a cardboard paper makes it possible to resist the risk of buckling while facilitating the assembly of the constraint members 4 by an operator. Logistically, a single type of material can be used to form the presentation walls 1, 2 and the holding inserts 3. FT print test sheets that were previously discarded can now be recycled as holding inserts 3, which makes it possible to reduce the ecological footprint of printers and / or display manufacturers.
