Abstract
Packaging article, made by means of a sheet of folding material, the article including a base wall, sidewalls connected with the edges of the base wall by folding lines. Two preferably opposite sidewalls include an extension flap, which protrudes from ends of the sidewalls and is connected thereto by a folding line. The extension flap folds, arranging itself in face-to-face relationship with a portion of the adjacent sidewalls. The packaging article includes connection means for fixing the extension flap on the portion of the adjacent sidewalls. The connection means include a male element and a female element configured in such a way that a portion of the male element, when inserted into the female element, protrudes towards the outside of the formed packaging article.

A method for manufacturing a packaging article (100) of a sheet (400) of foldable material, the method comprising:
- folding sidewalls (110, 120) along fold lines (103) and folding, along a fold line (113), extension flaps (111) that protrude from ends (112) of said sidewalls (110),
- arranging said extension flaps (111) in face-to-face relationship with a portion (121) of the adjacent sidewalls (120),
- fixing each extension flap (111) on the portion (121) by exerting a thrust action on the connection means (130) of the packaging article (100), with a movement directed from the inside towards the outside of the packaging article (100), and
- inserting the male element (131) inside the female element (132) so that a portion of said male element (131) projects from the female element (132), towards the outside of the packaging article (100).
