  • Patent number: 4228912
    Abstract: A container is formed by locating two panels in a jig so that the two panels have their adjacent edges nearly touching, the panels being in perpendicular planes. A mould is provided at the adjacent edges of the panels, and a casting resin is introduced to the mould to secure the panels together. Two pairs of panels thus formed are joined together in a similar way to form the walls of a container, and a base and lid are also connected to the walls in a similar way. The casting resin is a cold curing casting resin which, when cured is flexible. The panels are thus interconnected by flexible joints. The container is resistant against damage when dropped.
