ABSTRACT:
A cigarette packet of the rigid type having a hinged lid is fashioned in a mold, composed of a bottom die and a top die which combine to create two distinct voids and a slender channel by which the voids are interconnected. A moldable material is directed between the bottom die and top die, filling the voids and the channel completely and resulting in the formation respectively of a container, a lid, and a hinge connecting the lid to the container.
