A carton has a series of panels including top and bottom panels, side panels, and front and rear panels which collectively define an interior space for carrying wire or other filamentary material. The carton is formed from a unitary blank. The cartons can be set up by an automated machine without intervention of an operator. The carton include an interior channel located between two, aligned exterior holes located in opposing panels of the carton. The interior channel is formed from several hingedly connected panels, at least one of which is attached to the carton. The hingedly connected panels are folded around or rolled to form the interior channel, which is inserted into the carton. Once assembled a shaft or rod may be passed through one of the exterior holes, through the interior channel, and out the other exterior hole. The interior channel reinforces the structure of the carton and further allows the carton to hang from a shaft or rod without the carton tearing. |
