<p>The packaging frame, comprises a pair of identical frame parts integrally moulded of semi-rigid thermoplastic material, each including a planar, open rectangular portion made of four elements integrally joined at four corners and each having an L-shaped transverse cross-sectional shape having two walls joined at a respective outer edge of the respective frame part. Each frame part further includes four extensions each having one end integrally joined to a respective rectangular portion at a respective corner so as to extend in a like direction perpendicular to the respective frame portion. The pair of frame parts are arranged in confronting relation so that the other ends of the other frame portion and respective said extensions having abutting ends thereby form extensions of one another. The extension has an L-shaped transverse cross-sectional shape having two walls joined at a respective outer edge of the respective extension. Each extension further has integrally formed where the two walls are joined at an inside vertex.</p> |
