Description

DESCRIPTION

cardboard display

The present invention relates to a paper model of a display stand.

There are several types of prior art commercial displays made from blanks made of paper pattern materials, such as cardboard or corrugated board.

These exhibitors can have different shapes, depending on the type of merchandise or products to be supported. In particular, there are several displays on the market to support large merchandise, or to support a large number of items to be displayed, which require deeper shelves.

However, the shelves must be adequately reinforced. An example of reinforcement consists of special fins present on the side edges of each shelf that engage with the side walls of the display case, for example by inserting special grommets in the side walls of the display case. This prevents said shelves from coming into contact and breaking or, more frequently, bending towards the bottom of the central portion of the shelves, due to the weight of the goods to be supported.

Alternatively, these shelves may be supported by transverse bracing members, such as metal rods, or rods made of paper pattern materials.

However, both solutions present difficulties in the assembly of the displays, since both the insertion of the shelf fins inside the special eyelets and the insertion of the transverse reinforcing rods below the shelves must be carried out during assembly, with movements that can be complex for an operator.

Examples of displays comprising reinforced shelves are given in EP 2668876 A1 and in AU 2016319857 A1.

The object of the invention is to provide an alternative form of displays made from blanks, comprising deep reinforced shelves, which are simple to assemble. Another object of the invention is that said displays are made entirely from recyclable materials.

Finally, an object of the invention is that said blanks are easy to manufacture and cheap.

The invention relates to a set of blanks for assembling a paper model of a display case for displaying merchandise according to claim 1. Preferred embodiments are set forth in its dependent claim 2.

Furthermore, the invention relates to a paper model of a display stand for exhibiting goods obtained by assembling a set of blanks of claim 1, as described in claim 3. Other embodiments are defined in dependent claims 4. -8.

The invention will now be described, by way of example and without limiting the scope of the invention, with reference to the accompanying drawings, in which:

Figure 1 shows a perspective view of a display case according to the invention;

Figure 2 shows a detailed perspective view of a shelf of the display case of Figure 1;

Figure 3 shows a perspective view of a detail of the display case of Figure 1, during an assembly stage;

Figure 3b shows a perspective view of the detail of Figure 3a, after assembly;

Figure 4 shows a front view of a first blank for manufacturing the rear portion of the display case of Figure 1;

Figure 5 shows a front view of a second blank for making the front portion of the display case of Figure 1; Y

Figure 6 shows a front view of another blank for manufacturing a shelf of the display case of Figure 1. Figures 1 — 3 show the display case according to the invention indicated with the reference number 1. According to the embodiment shown in the drawings, said display case 1 comprises a rear wall 2, two side walls 4 and four shelves 5. In particular, each side wall 4 is adjacent to the rear wall 2 at a respective inner corner 16. Furthermore, said display case 1 comprises a front portion formed by a fenestrated front surface 3, comprising in particular three openings 19 such that each shelf 5 can be placed either inside a respective opening 19 or in the upper portion of said display unit 1 above said front surface 3.

Each shelf 5 comprises two lateral edges 6 and a rear edge 20, when each shelf 5 is placed on said display case 1, said lateral edges 6 are placed close to said side walls 4, in particular in contact with them, and said rear edge 20 it is placed close to said rear wall 2, in particular in contact with it.

According to alternative embodiments, the display case 1 can have a different number of shelves 5 and a different number of openings 19.

Said display 1 also comprises two vertical struts 7, one for each side wall 4, protruding from the respective side wall 4 towards the inside of said display 1. In particular, each strut 7 comprises a longitudinal 8, with a depth of between 20 mm and 60 mm, and a projection 9 for each shelf 5, with a depth between 45 mm and 95 mm.

Each strut 7 divides the respective side wall 4 into a rear portion 4', from said rear wall 2 to said strut 7, and a front portion 4" from said strut 7 to said front surface 3.

In the particular embodiment shown in Figures 1-3, said struts 7 are placed substantially in the center of the respective side wall 4, said rear portion 4' having substantially the same extension as said front portion 4".

Again, according to the preferred embodiment shown in Figures 1-6, each strut 7 can be assembled by gluing a first contoured portion 7' formed from a first blank 100 to a second contoured portion 7" formed from starting from a second blank 101, in which said first contoured portion 7' has the same profile as said second contoured portion 7".

In this way, advantageously, two resistant struts 7 are obtained, since the collapse of each strut 7 towards a portion 4', 4" of said side walls 4 is avoided.

Each shelf 5 comprises a notch 10 on each lateral edge 6, located on a respective strut 7 and directed towards the inside of said shelf 5.

Each notch 10 preferably has a dimension greater than or equal to the depth of said longitudinal bodies 8 and less than the depth of said projections 9. In this way, said shelves 5 can be easily inserted inside said walls 4, 2 after the body 8 of the respective strut 7 has been inserted into the respective notch 10 of each shelf 5, so that each shelf 5 is advantageously supported below by the respective pair of projections 9, on its lateral edges 6, resting against said projections 9.

Specifically, said projections 9 substantially have a rectangular triangle shape, having the right angle in said longitudinal body 8 and the respective shelf 5.

The specific shape of said projections 9 has the double advantage of obtaining a good support using the least amount of material possible and not occupying the display space of the merchandise or products of any underlying shelf.

In addition, the uprights 7, that is, the supports of said shelves 5, can advantageously be made of the same material as the display 1, such as recyclable paper model materials, such as corrugated cardboard.

Each shelf 5 can also be supported below said rear wall 2 and on said front surfaces 3. In fact, at each inner corner 16 placed between the side walls 4 and said rear wall 2 there are four angular supports 11, that is, a support angular 11 for each shelf 5.

Each angular support 11 is placed at the same height as a respective projection 9 of said strut and comprises a continuous surface of which a portion is common with said rear wall 2 and a portion is common with the respective side wall 4.

In fact, said continuous surface is manufactured from said rear wall and from said respective side wall by means of cuts, which in the particular embodiment shown in Figures 1-8 have a substantially semi-circular shape, to create a pair of angular supports 11 for each shelf 5, which support said shelf 5 below, leaning against it near the rear wall 2 of said display unit 1.

In this way, said angular supports 11 advantageously reinforce the support of the respective shelves 5.

Furthermore, each shelf 5 may comprise at least one rear flap 13 inserted within a specific eyelet 12 of said rear wall 2, to further favor the support of said shelf 5 close to the rear wall 2 of said display unit, said eyelet 12 which it is placed substantially at the same height as a respective pair of projections 9.

Advantageously, said coupling between the eyelet 12 and the respective rear flap 13 makes it possible to secure the shelf 5 during assembly, thus facilitating it.

Lastly, each shelf 5 is supported from below close to said front surfaces 3 of said display unit 1, since each side wall 4 may comprise a front flap 14, located on a respective projection 9 and projecting from said display unit 1, supporting said shelf 5 below, leaning against it.

According to a preferred embodiment, at least one shelf 5 can have a dimension greater than the dimension of said side walls 4, so that it protrudes partially in front of said side walls 4 when said display unit 1 is assembled and can accommodate a larger number of products to exhibit. Said protruding portion of said at least one shelf 5 can therefore advantageously be supported below by said side flaps 14, said side flaps 14 being able to protrude with respect to said side walls 4.

Furthermore, each shelf 5 may comprise a front plate 15, said front plate 15 being glued on the respective portion of the front surface 3 of said display case 1.

In this way, advantageously, there is a display unit 1 in which the shelves 5 are supported from below at various points, consequently obtaining reinforced shelves, which can also be deep, whose reinforcements are all made of the same material as the display unit. , for example, corrugated cardboard, and therefore completely recyclable.

Figures 4 — 6 show a set of three blanks from which said display 1 can be obtained.

In particular, said three blanks are respectively:

- a first blank 100, adapted to form said rear wall 2, said rear portion 4' of each of said side walls 4, and said first contoured portion 7' of said strut 7; a second blank 101, adapted to form a second contoured portion 7" of each strut 7, said front portion 4" of each of said sidewalls 4 and said front surfaces 3; Y

a third blank 105 for each shelf 5.

In particular, said first blank 100 comprises four fold lines 116, 117, in particular fold lines, and two contoured side edges 118. Said contoured side edges 118 form four projections 109' each, to form four pairs of projections 109', one for each shelf 5 to be inserted in said display case 1. In the embodiment shown in Figures 4-5, said projections 109' have substantially a rectangular triangle shape with a right angle and facing upwards.

In particular, said fold lines 116, 117 are formed by a pair of first central fold lines 116 and a pair of first lateral fold lines 117 for dividing said first blank 100 into five surfaces, of which:

a first central surface 102 comprised within said pair of first central fold lines 116, adapted to become said rear wall 2;

two respective first side surfaces 104', comprised between one of said first central fold lines 116 and a respective first side fold line 117, and adapted to become said rear portions 4' of side walls 4; Y

two respective first contoured portions 107', comprised between a respective first lateral fold line 117 and a contoured lateral edge 118, adapted to become said first contoured portions 7' of said struts 7.

Said second blank 101 in turn comprises two pairs of fold lines 120, 121, preferably fold lines, and two contoured side edges 122 delimiting four projections 109" each, to form four pairs of projections 109", one for each shelf 5 to be inserted in said display case 1, said contoured side edges 122 preferably having the same profile as the contoured side edges 118 of said first blank 100. In particular, said two pairs of fold lines 120, 121 are respectively a pair of second central fold lines 120 and a pair of second lateral fold lines 121, and divide said blank 101 into eight surfaces, of which:

a second central surface 103, fenestrated, ie comprising three openings 119, adapted to become said front surfaces 3, said central surfaces 103 being within said pair of second central fold lines 120;

two respective second lateral surfaces 104'' comprised between one of said second central fold lines 120 and a respective second lateral fold line 121, and adapted to become said front portions 4'' of the side walls 4; Y

two respective second contoured portions 107", comprised between a respective second lateral fold line 121 and a contoured lateral end 122, adapted to become said second contoured portions 7" of said struts 7.

During the assembly of said display stand 1, all the fold lines of said first blank 100 and second blank 101 are folded with a valley fold with respect to the respective inner faces 100', 101', forming said contoured portions 107', 107" at a substantially orthogonal angle with the respective lateral surface 104', 104", so that each contoured portion 107' of said first blank 100 can mate with a respective contoured portion 107" of said second blank 101, or for example by gluing, to form said two struts 7.

In this way, advantageously, said display stand 1 is easy to assemble, since a limited number of blanks 100, 101, 105 are used, and the coupling of said contoured portions 107', 107" is easy to achieve, since said contoured stickable portions 107', 107" are easily accessible.

Lastly, said third blank 105 can be formed from a single surface comprising two respective edges 152 with cuts 110, adapted to form said notches 10, said two edges 152 being parallel to each other.

However, preferably, as shown in Figure 6, said third blank 105 may comprise two overlapping surfaces 150, divided by a respective fold line 151, each comprising said cuts 110, and comprising, in another edge 153 of one of said two overlapping surfaces, substantially orthogonal to at least one edge 152 comprising said cuts 110, a front portion 115, adapted to form said front plate 15. Furthermore, at said fold line 151 there may be a contoured flap 113, adapted to form said rear flap 13, so that each shelf 5 can be formed by folding over itself said fold line 151, that is, by superimposing said two overlapping surfaces 152, and in such a way that said shelf 5 can be inserted into said exhibitor 1.

In the case of the example, four third blanks 105 will be used to form four respective shelves 5, in which said front portion 115 of each third blank will be attached, for example by gluing, to a respective central surface 103 of said second blank 101.

According to alternative embodiments of said display unit 1, for example in the case of display units having a number of shelves 5 different from four but greater than or equal to one, said first and second blank 100, 101 may have a number of projections 109 different from four, but equal to the number of shelves of said display, and said second blank may have a number of openings different from three, but sufficient to allow the insertion of each shelf 5 inside display 1.

With reference to Figure 4, it should also be noted that in each first center fold line 116 of said first blank 100 there is provided at least one pair of cuts 111, depending on the number of pairs of cuts 111, the number of shelves 5 of the exhibitor 1. In particular, each pair of cuts 111 comprises two cuts 111 that cut part of said first central surface and part of the respective first lateral surface, said two cuts being substantially the mirror image of each other with respect to a horizontal line of said first blank 100. For example, according to the preferred embodiment shown in Figure 4, said cuts have a substantially semi-circular shape.

The folding portion 111' delimited by said two cuts 111 is adapted to form said angular supports 11 when said display unit 1 is assembled.

In particular, to facilitate the formation of each angular support 11, each foldable portion 111' may comprise a median fold line 116' substantially collinear with the respective first central fold line 116, but adapted to fold upwards with respect to said face. 100' of the blank 100 during the assembly of said display 1. In addition, said folding portions 111' may comprise two perimeter fold lines 123, a perimeter fold line 123 for each wall 102, 104', said fold lines perimeter 123 that are substantially parallel to said median fold line 116', as it is perimeter to said folding portion 111', and that are adapted to fold downward with respect to said face 100' of said blank 100 when said display 1 is assembled.

Finally, with reference to Figures 2, 5 and 6, it should be noted that:

- each second lateral surface 104" of said second blank 101 comprises a lateral flap 114 at each opening 119, said lateral flaps 114 protruding towards said opening 119 and are divided by the respective second lateral surface 104" by a fold line interior 125, in such a way that, when said display unit 1 is assembled, said lateral flaps 114 of said second blank are folded with a valley fold with respect to said interior face 101' that forms said front flaps 14, to support by below the portions of said shelves 5 in the front part of said exhibitor.

The preferred embodiments have been described above and variants of the invention have been suggested, but it will be understood that the invention can be modified and/or adapted by those skilled in the art without thereby departing from the scope of the inventive concept, as defined in the claims in the present memory.
