  • Rigid hinged-lid packet for the stable packing of groups of long elements of variable size
    Patent number: 5819925
    Abstract: The rigid packet with hinged lid includes a container for a group of long elements and a lid hinged at a top, open end of the container, each having a front, a back and two sides; inside the container, fixed to and partly protruding from the latter, there is a collar with three consecutive flaps which have one or more notches defining respective tabs, hinged with their hinged side to the collar, folded inwards in the container and in contact with the group of long elements so as to form flexible compensation elements which recover the play present between the container and the group of long elements due to the reduction of the size of the latter compared to the fixed internal dimensions of the container.
