Carriers for containers, apparatus and method for applying the same to containers, such as bottles (B), and made from such material as paper board formed to operate as levers able to withstand tension and compression and arranged as a four-sided tube either singly or with another alongside it and connected. Openings (10 and 14) in the top and bottom of the tube to admit each container, at least one side wall (4a, 4b or 6a, 6b) deformable inwardly along a line to grip each container and such side wall above and below the line of deformation stressed compressively. The joint (15) forming the paperboard into a tube utilises the compressive force and the stiffness locked into such side walls and which form the ends of the blank, by arranging them as force components at an angle and in opposition one to the other and their resultant force resisted, by a relatively immovable and receptive part of the carrier with containers holding the confluence of the side walls captive, thereby making the ends of the blank secure in a radial plain. The ends of the blank are further secured axially by providing the ends of both such side walls with interlocking tongue extensions (21 and 22) so that an effective joint is made in total. |
