EP1693303A1 - Cardboard tray and blank, display stand comprising the tray and a support and method for making the display stand - Google Patents

Abstract

The tray has two lateral walls and internal proximal and distal walls forming an article receiving a space, where the lateral walls extend above a roll line via blocking flaps. The blocking flaps have guiding panels with tabs cooperating with rectangular flaps (22b) and distal guiding flaps (23b) to form, with panels, an external apron around a central bottom part (21). The apron and the walls form a space to receive a wall of the base. An independent claim is also included for a method for forming a display rack.

Description

The invention relates to a compact cardboard box, corrugated cardboard, plastic material or similar flexible material, or even metal material (aluminum, etc.), the blank of constitution of this tray as delivered flat, a display formed by this tray associated with a suitable structure support, the support being set in volume and used directly on site to receive items for storage and / or presentation, and the method of producing such a display.

In the following description, reference will be made essentially to the cardboard (compact or corrugated) but only for the sake of simplicity of the disclosure, the invention is not limited to this single material.

Point-of-Sale Advertising, abbreviated PLV, is an important activity of the cardboard industry. Products used for POS are generally cardboard displays to receive items for presentation, storage and / or transportation. The display stands are of a size, shape and appearance specifically adapted to the product.

This type of sale is most often promotional and displays are installed "at the head of gondola", that is to say at the entrance and / or exit of the shelves of small, medium or large stores. Space saving is an important economic factor because these sites are expensive.

During predefined periods, the advertiser or the big box itself makes important promotions. The mass effect (large display, large number of products) marks the spirit of the consumers and plays a major role in their purchase decision.

Thus, the need to exploit all the available space as well as to create a mass effect has led manufacturers to conceive of many POS displays, allowing a staggered presentation of products on different heights.

For example, parallelepiped display units whose upper face is inclined to receive a tray where the products are stored. This inclination allows a better presentation while allowing the combination to another display of the same shape, but of lower or higher height for a staged presentation of the products. Such a combination is for example described and illustrated in French Patent Document No. 0307060 filed in the name of the Applicant.

The storage bins are most often made of thermoformed material, for example PVC, or cardboard bonded at the factory. These bins therefore occupy an important place because they can only be delivered in volume.

Bonded cardboard bins also have a complex structure that limits mounting by a user.

The invention aims on the contrary to provide a cardboard tray that can be delivered, optionally, in volume or flat. When delivered flat in the form of a blank, it can be put in volume easily and quickly on site. To do this, the invention proposes to combine means of successive folds to blocking, guiding and connecting means from the blank. In addition, the tray according to the invention is environmentally friendly because it involves little or no polluting fastening materials (glue, adhesive).

More specifically, the invention relates to a cardboard tray, flexible material or the like intended to be set in volume in connection with a base, having along a longitudinal axis a bottom having a central portion, two end portions. transverse, respectively proximal and distal, as well as two side walls for forming, after folding end portions and side walls along lines delimiting the central portion, a receiving space for presentation and / or storage articles. In this tray, each side wall is extended, beyond a fold line, by a locking flap, itself extended longitudinally, beyond a fold line parallel to the previous, by a panel of a guide which comprises means for holding the longitudinal ends, in that these holding means co-operate with transverse guiding flaps of the end portions to form, together with the guiding panels, a stiffened external skirt and erected around the central part of the background. The base has a wall adapted to be inserted into the tray, on the one hand, against the guide panels and, on the other hand, against the guide flaps.

Such a solution makes it possible to produce a display of height adapted to the presentation, but also to constitute an element of a set of construction (wall, stage, pyramid, counter, display, etc.), or to be covered with an illustration constituting alone, or in combination with other modules, an advertising medium or decor.

Figure 1 illustrates an example of flat blank 10 according to the invention, cut and grooved in a sheet of cardboard. It has a background 20 substantially rectangular, having a central portion 21 extended transversely, that is to say in the direction Y'Y perpendicular to the longitudinal direction X'X of the blank, by:

• a first proximal portion 22 of three substantially rectangular flaps, 22a, 22b and 22c, from the nearest to farthest from the central bottom portion 21, the flaps being able to articulate around fold lines L1 to L3; and
• a second distal portion 23 of three substantially rectangular flaps 23a to 23c, from the nearest to the farthest from the central portion 21, articulated around lines L4 to L6, the last flap 23c being optionally completed by a strip 23d which has a front face - glued.

The central bottom portion 21 is extended longitudinally by side walls, 24a and 24b, hinged around fold lines L7a and L7b. The side walls themselves are extended, beyond fold lines L8a and L8b, by locking flaps, 25a and 25b. These side walls have a trapezoidal type geometry with non-parallel bases. The sides 24c are inclined with respect to the longitudinal axis X'X. The side walls, their fold lines and their flaps, are collectively referenced respectively by 24, L7, L8, and 25.

Each flap 25 has a guiding panel 26a, 26b articulated longitudinally around a fold line L9, L9b parallel to the line L8a, L8b respectively, and provided with a proximal connecting tab 27a, 27b extended by a lug 29a, 29b and a distal link tab 28a, 28b. The tongues 27 and 28 are articulated transversely on the corresponding guide panel 26, around lines Lp and Ld, and are intended to cooperate, respectively, with the proximal guide flaps 22b, 22c, and distal 23b, 23c. Guide panels, fold lines, proximal and distal tabs, and retaining lugs are collectively referenced by, respectively, 26, L9, 27, 28 and 29.

The use of the same reference signs is justified for symmetrical elements according to a central plane P passing through the longitudinal axis X'X.

Two slots F are cut along the fold line L2 between the first proximal flaps 22a and 22b to include in particular the retaining lugs 29 during assembly. The proximal guide flaps 22b and distal 23b have widths substantially identical to the width of the guide panel 26 at the corresponding hinge lines Lp and Ld.

Other bottom slots Ff are cut in groups of three along three transverse lines Lf of the bottom 20, as well as along the folding lines L1 and L4 of articulation of the central bottom portion 21 on the first flaps. respectively 22a and 23a. To simplify the preparation, the slots can be made in the form of simple cutouts D, as illustrated along the line L1 in the exemplary embodiment. The bottom slots are intended to receive anchors of a presentation support, as explained below.

The sidewalls and the flaps are erected around the fold lines L7, L1 and L4 to form, in use, a receiving space as also explained hereinafter.

The mounting of a tray corresponding to this blank 10 is illustrated in Figures 2 to 6 by a first series of steps of setting volume of the blank. This first series relates to the mounting of the side walls 24, guide panels 26, and proximal walls formed from the proximal flaps 22a to 22c.

The proximal flaps are first raised (Figure 2) to the central portion 21 around the fold line L1 (arrow F1, Figure 1) and folded around the line L2 (arrow F2, Figures 2 and 3) simultaneously with the folding the side walls 24 around the fold lines L7 (Figure 3, arrow F3).

Then, with reference to FIG. 4, the locking flaps 25 and the guide panels 26 are pivotally folded around fold lines L8 and L9 (arrow F4), so that the panels are at a distance from the corresponding walls 24, while inserting the connecting tabs 27 under the fold formed between the two first proximal flaps, 22a and 22b (arrows F5a and F5b) by pivoting about the line L2 (arrow F6).

FIG. 5 shows the result of the preceding swivels: the guiding panels 26 are arranged parallel and at a distance from the side walls 24 and the lugs 29 appear plugged into the slots F. The first proximal flap thus set up forms the internal proximal wall 22i and the side walls 24, erected substantially perpendicular to the central portion 21, define an interior space E of the tray 11 during assembly.

The last proximal flap 22c is then folded around the line L3 (arrow F7) to also come into the slots F through advances 29v, while wrapping the connecting tabs (Figure 6). The elastic stiffening thus obtained between the guide panels 26 and the folded guide flaps makes it possible to define a first outer skirt portion 100 composed of these panels and the outer proximal wall 22e formed by the guide flap 22b.

With reference to FIGS. 6 to 9, the second series of volume-setting steps relates to the assembly of distal walls from the distal flaps 23a to 23c, to complete the internal and external walls of the container and to form an internal space and a continuous outer skirt.

The distal flaps 23a to 23c are raised (arrow F8 of Figure 6) by pivoting around the fold line L4 so that the first distal flap 23a comes to bear against the side walls 24a and 24b.

In the nonlimiting example illustrated, the flap 23a, once in place (FIG. 7), is inclined relative to the central bottom portion 21, of the the flap 23b is folded (arrow F8a) around the fold line L5.

FIG. 8 shows the introduction of the tongues 28 (arrows F9a and F9b) by rotation around the lines Ld, during the pivoting (arrow F10) of the distal flap 23b around the line L5, between the two first distal flaps 23a and 23b. The third distal flap 23c is folded around the tongues 28 (arrow F10a) to position, perpendicular to the central bottom portion 21, the set of guide flaps 23b, 23c, 23d and the connecting tabs.

Figure 9 shows in transparency, in enlarged rear view of the tray 11, the final pivoting of the distal flap 23c and the band 23d, the band coming to fit and align under the tabs (only the tab 28a is shown). The set of guide flaps 23b, 23c, 23d and the connecting tabs form an external distal wall 23e complementary to the outer skirt 100.

Referring to Figure 10, the tray 11 appears after placing all the walls: inner proximal wall 22i, inner distal wall 23i and sidewalls 24, forming a continuous closed belt K and defining the interior space E of the tray. The tray has an internal distal wall 23i inclined relative to the side walls, of width substantially twice as large as the inner proximal wall 22i, also inclined. The side walls 24 are of continuously variable width so as to adapt to the different widths of the proximal and distal walls. Such a difference in width allows for a good presentation of articles even placed in the background. The guide panels 26 and the outer walls, 22e and 23e distal, form the outer skirt 100.

To further improve this presentation, it is planned to combine (arrow F11) this tray 11 with a support 12 for receiving articles, as shown in Figure 10, to form a display 13.

The support is made by cutting and grooving in a sheet of cardboard. Tabs 30 are formed by cutting on the transverse sides of the support 12 as well as along an intermediate line Li transverse, corresponding to a line Lf of slots Ff of the central portion of the bottom 21, once the support set up. Two lines of folds L9 and L10 are formed between two lines of legs 30 and the support is folded along fold lines L10, L11 and Li so as to insert the tabs 30 in the corresponding slots Ff of the central portion 21 of the bottom.

Referring to Figure 11, the display 13 is used as a cooperative display base (arrows F12) with a cubic base 40 to achieve a new height display suitable for a presentation in foot. The base has a wall 41 adapted to fit on the inner faces of the outer skirt 100 in a tight but reversible manner.

The invention is not limited to the examples described and shown.

It is for example possible to produce displays of suitable shape (trapezoidal, etc.), to adapt the shutters to fix them to the central part of the bottom by any known and adapted means (crimping, gluing, clipping, snapping, screwing, etc.). In addition, the number and organization of the slots of the presentation support and those of reception on the central part of the bottom, as well as the shape of the folds of the support, can be adapted to the type of articles to be presented.
