ABSTRACT:
A one-piece tube multi-pack and its method of manufacture are disclosed. The one-piece tube multi-pack includes an elongated thin-walled tubular element made of transparent flexible plastic material with inner and outer peripherally extending walls. At least one thin-walled web section is integrally connected to the inner peripheral extending wall of the tubular element and has greater flexibility than the tubular element in order to adjustably accommodate a plurality of separate discrete products positioned on opposite sides of the at least one integral web section. The at least one integral thin-walled web section may be connected to the inner peripherally extending wall of the tubular element at different relative locations, for example, in a spiral or curvilinear or other shaped path throughout the tubular element. The method for making the one-piece tube multi-pack includes the extrusion of the elongated thin-walled tubular element and the at least one thin-walled web section with greater flexibility than the tubular element. When formed to extend at different relative locations throughout the tubular element, such as a spiral or curvilinear or other shaped path, the tubular element is twisted while in a heated state to form the shape throughout the tubular element. The tubular element can be forced having a pair of channels formed in the outer peripherally extending wall with spirally extending ribbons of non-transparent material co-extruded and inlayed in the channels.
