At this time of year, parcel delivery companies use millions of metres of tape to seal up boxes.
Sometimes their choice of box size is suboptimal, but today’s invention is more concerned about the overuse of tape. This also makes more difficult the task of recycling the cardboard boxes themselves.
Instead of applying tape to every cm of box seam, boxes would be made with just a little extra material, to allow for the formation of a tang and slot(s) combination, every few centimetres.
These could be made so that a machine could engage the tangs with the slots firmly.
