The present invention relates to a packaging, and more particularly a packaging made of a semi-rigid material, such as, for example, corrugated or sheet-form card material or a similar material, intended to hold products for their store and transport and, as necessary, to be turned into a display packaging in which the products are displayed for sale, such as a “Shelf Ready Packaging” or a RRP, for “Retail Ready Packaging”. The term “products” is used to describe sales units or logistics units. These various types of packaging, regardless of their combined or individual purposes, are commonly known as primary packaging, secondary packaging or tertiary packaging by product packagers and their logistician or distribution customers.
In the field of packaging, the use of retail ready packaging is well known and allows significant savings in terms of time and cost, with respect to conventional packaging, for which it was necessary to remove the products in order to place them on the shelving of retail areas.
This is the case, in particular, for document EP 0 965 528, which describes a box with eight panels of sheet-form card made from a preform comprising a succession of eight rectangular flaps forming the side walls of the box and ended by a rectangular attachment strip, said flaps and said strip being connected to one another by first fold lines parallel to one another, i.e. four main flaps separated in pairs by four intermediate flaps, said intermediate flaps not having a tab, a first set of lateral tabs arranged on one side and connected to the primary flaps by second fold lines and forming at least partially the bottom of the box, and a second set of lateral tabs arranged on the other side of the flaps forming the side walls, to which it is connected by third fold lines perpendicular to the first fold lines and intended to form at least partially the lid of said box. The free sides of the intermediate flaps oriented towards the side of the tabs comprise protrusions, and the free sides of the intermediate flaps oriented towards the side of the tabs comprise indentations. Thus, the end flap of the succession of flaps and the strip on one side, and the tabs on the either side, are secured by applying them onto one another and by gluing, said box being mounted automatically by folding back said flaps and the tabs of said first set around a mandrel.
Retail ready packaging is also known, said packaging being formed by parallelepiped packaging comprising a peripheral cut line delimiting the base and the lid of the packaging and enabling the removal of the lid, after cutting operations along the peripheral cut line, to render accessible the products contained in the base, which is directly placed on the shelves of stores. Specifically, this is the case for Japanese patent application JP2009241958 and U.S. Pat. No. 6,135,289.
Document JP2009241958 and document U.S. Pat. No. 6,135,289 describe a retail ready packaging cardboard box comprising a peripheral wall formed by a front wall, a pair of side walls and a rear wall. An inclined cut line is provided in the two side walls so that the upper part of the cardboard packaging can be removed by breaking the cardboard packaging along the cut line to convert the cardboard packaging into a display for products.
French patent application FR 2 783 803 discloses a packaging made of a semi-rigid material that can be turned into a display. The packaging comprises a corrugated cardboard box closed at one end, open at the other end, and comprising at least three side walls, one of said side walls having a low-resistance line, the ends of which extend to the upper edge of said side wall, and that defines internally a tear-away pre-cut, and a lid made of corrugated cardboard material comprising a bottom wall and a side skirt, said lid covering the open end of the box and being secured thereto, by gluing the skirt on said pre-cut and on at least another wall of the box.
All these types of cardboard packaging have the disadvantages of being costly, considering the quantity of raw material used for each packaging, in particular the significant paper grade used, and of featuring insufficient mechanical resistance, in particular for packaging in the form of a box with pre-cuts and/or of the type comprising a tray and a lid, and are therefore unable to withstand the constraints of modern logistics, such as automatic palletising or processing on platforms for bulky product.
One of the purposes of the invention is therefore to overcome these disadvantages by providing a retail ready packaging and/or a grouping and shipping packaging of simple and inexpensive design, featuring high mechanical resistance and easily formed by means of a flat forming machine by pressing-bending or around a forming mandrel.
