Title:
METHOD, MACHINE AND DEVICES FOR PRODUCING FLEXIBLE 3D PACKAGING, BY MEANS OF FOLDING A FLAP ON ITSELF
Document Type and Number:
WIPO Patent Application WO/2017/021570
Kind Code:
A1
Abstract:
The invention relates to methods and devices for transforming flexible, sealed packaging having at least two faces and containing at least one fluid and, optionally or complementarily, at least one solid, granulated and/or powdered, into three-dimensional packaging by folding or bending, at least once in at least one direction, at least one part of at least one flap/triangular body (38) or strip (37) on at least part of another part of the same flap/triangular body (38) or strip (37). In addition, beforehand and/or subsequently, at least one part is sealed at least once along at least one face of the flap/triangular body (38) or strip (37) produced, and/or same being folded/bent on itself at least once. This system involves improvements related to the inalterability of the packaging and to the economic and environmental aspects, since it is not necessary to cut the flaps or triangular bodies, the wrapping of the initial packaging transformed into 3D thus remaining intact without tears or rips. The following features are also important: the preservation and shelf life of the packaging, without holes or leakages, is guaranteed, from the transformation into 3D until the subsequent opening thereof and consumption of the packaged product; no adherent or contact adhesive, for example glue, or a strip of tape, is necessary to adhere or fold the flat/triangular body (38) or strip (37); in the production plant, the packaging transformed into 3D is prevented from being produced with defects; the packaging of the invention is more stable, due to the support face being wider and more consistent, since the packaging comprises at least part of the flap/triangular body (38) or strip (37) as a support surface at the base.
