Abstract: An outer pack for wrapping around at least one object has a top panel, two side panels, two base panel sections at least partially overlapping one another and forming a base, and a structure for connecting the base panel sections with one another. The connecting structure includes a plurality of hook-shaped closure elements provided in one of the base panel sections and composed substantially of two sections located one behind the other and including an inner section hinged to the one base panel section along a folding line and interrupted by a cut curving into the one base panel section and forming a projection, and an outer section hinged to the inner section along a further folding line with both sections having a substantially trapezoidal shape.

Abstract: Packaging of the tube type has a bottom wall (100) constituted by a single piece. In the bottom region of an end opening, a continuous skirting (101, 102) is hinged to the bottom and is connected laterally to adjacent portions of the packaging (300, 110) by flaps (103, 104) for holding the skirting in an upright position. At least one locking tab (410, 412) projects from an end edge of one of the walls (400) and includes a central portion (410) together with at least one wing (412). A locking opening (114) is provided in the opposite region of the blank, in the vicinity of a hinge (P3) between another main (100) and a locking flap (110). Each tab is inserted into a corresponding opening by temporarily deforming the associated wing(s). The invention is particularly suitable for providing the outer packaging of primary containers.
