Description

The present invention relates to a support device configured for producing a device for packaging a floral arrangement with a water reserve.

The invention also relates to a packaging system for floral arrangements having a support device according to the invention, as well as a decorative sheet. The invention also relates to a method for producing a floral arrangement using a packaging system according to the invention.

The field of the invention concerns the field of flower bouquet packaging, and more precisely packaging with water reserves.

In general, such packaging devices for flower bouquets comprise a waterproof packaging film, made of plastic material, typically made of polypropylene intended to constitute a water reserve, and a structural support element, very often made of plastic material. rigid or semi-rigid, intended to give its shape to the packaging and to allow the packaging to be held stable on a horizontal surface. Once the packaging has been formed, the waterproof film wrapped on the support element, and the water reserve formed, a ligature allows the leaf to be tied to the support, while maintaining the stems of the bouquet.

The document EP 0 881 167 A1 describes such a packaging device which comprises a support element having a substantially circular base with a raised edge and on the perimeter of which extend a plurality of elongated elements in the rest position. This element is typically a single-piece, injection-molded plastic element. The elongated elements are flexible and can be elastically deformed to be grouped towards the central axis of the base, in a position where the free upper ends of the elongated elements bear on the bouquet stems, said elongated elements being held in this position by placing a link.

In the rest position, these elongated elements follow a geometric configuration in the shape of a truncated cone, which allows them to be stacked one inside the other, during storage, and in order to limit their bulk.

For the creation of a floral arrangement with water reserve, and as illustrated in Figure 4 of document EP 0 881 167 A1 this support element is associated with a waterproof polypropylene sheet wrapping the support element, by grouping the elongated elements towards the central axis of the base against the stems of the bouquet of the floral composition, and by placing a ligature forming the neck of the floral arrangement. The propylene sheet typically includes excess material, above the neck, with the formation of a flare protecting the flowers of the bouquet.

In such packaging, the function of the support element is to ensure the stability of the floral composition when placed on a horizontal surface, the ends of the elastically deformed elongated elements coming into contact with the stems of the bouquet. This deformed support element forms a structure giving its shape to the polypropylene sheet, below the neck of the bouquet.

On the other hand, the water reserve function is provided by the polypropylene sheet which must necessarily be watertight.

Such state of the art according to EP 0 881 167 A1 requires two plastic elements, namely the support element, typically injection molded, as well as the waterproof sheet, typically polypropylene which must be large in size to envelop this support element, with the formation of a sheet flare above the collar of the bouquet. As the polypropene sheet serves as a decorative sheet, a large number of references are necessary, with different colors and patterns, in order to meet market demand.

According to the inventor's findings, this large number of plastic references is not ideal in that polypropylene sheets are not easily recycled.

We still know of the document FR2 946 025 A1 a packaging device suitable for creating a floral arrangement with water reserve.

This device notably comprises two sheets of flexible material, glued to each other, one decorative provided with a collar, the other waterproof secured to a frame. The bonding of the two sheets is such that it creates a sheath for a tightening link whose two ends pass through a push guide.

The frame has a cylindrical axis in its central part, and stiffeners articulated via flexible hinges in the central part. A shaper, made of rigid material, has a base in the form of a disc with a hole intended to receive the axis of the frame. This hole ensures the centering of the shaper on the frame. The shaper further comprises slats extending projecting from the disc.

The stiffeners of the reinforcement extend substantially flat in the rest position, and come when tightening the link, resting on the slats of the shaper to give its shape to the packaging and as illustrated in the Figure 3 of this anteriority. This prior art thus facilitates the formation of the floral arrangement. However, this device which includes several distinct materials glued to each other (the decorative sheet, the waterproof sheet, and the frame) is not easily recyclable at the end of its life.

The aim of the present invention is to propose a support device configured for the production of a device for packaging a floral composition with water reserve, which overcomes all or part of the aforementioned drawbacks.

More particularly, the invention makes it possible to obtain a floral composition with a water reserve, advantageously without requiring a waterproof sheet of such a size as to hide the support device, or even to form a leaf flare above the floral composition.

Another aim of the present invention is to propose a packaging system for floral arrangements comprising a support device according to the invention with a water reserve function, as well as a removable decorative sheet.

In particular, the aim of the present invention is to provide such a packaging system that is easily recycled, and compared to state-of-the-art packaging.

Another aim of the present invention is to propose a method for producing a floral arrangement using a packaging system according to the invention.
