Blank of cardboard or like material comprising at least one strip and two tongues all three provided with an adhesive for the setting up of a container with an inviolable closure

Abstract

The blank of cardboard or similar material, has cutout lines and score lines within a periphery cutout to a sheet and thus subdivided into elements of which certain ones are if desired glued flat against each other, said blank being adapted to be sold and stored flat, then ultimately to be bent, set up, and held bent thus constituted in a container for objects to be packaged, the setting up of the blank and the insertion of the objects being carried out manually and individually for each blank. It is characterized in that among the different elements of the blank, there is a strip of a single thickness ( 7 ) secured to two tongues also of a single thickness ( 8 and 9 ) located in prolongation of the ends of said strip ( 7 ), such that after setting up the blank and construction of the container, the strip ( 7 ) can be applied against the external surface of a surface ( 4 b , 44, 2 ) of said container, and that the two tongues ( 8 and 9 ) can be folded down and applied against the external surface of two opposite side walls ( 5 and 6 ), adjacent said surface ( 4 b , 44, 2 ), either directly, or with the interposition of at least one doubling panel ( 51 - 52, 15 - 16, 151 and 152 ), the setup container being adapted to hold its shape and to be closed irreversibly, and hence inviolably, by means of adhesive ( 12 ) disposed between the strip ( 7 ) and its two tongues ( 8 and 9 ) on the one hand and the three adjacent surfaces ( 4 b - 44 - 2, 5 and 6 ) on the other hand.
