US Patent 7594581 Collapsible container

The present invention includes a collapsible container defined by a continuous rigid structure and an interior liner that is uniformly affixed thereto. The continuous rigid structure is preferably four-sided such that it defines four continuous surfaces of a cube. The continuous rigid structure is collapsible due to at least one scoring line defined on at least one surface thereof. The liner is integrally affixed to each of the four sides and additionally provides a fifth side that forms the bottom of the container. A protective cover is secured to the exterior of the continuous rigid structure for protecting the contained materials against the elements. The cover can be selectively sealed for rendering the container of the present invention substantially impervious to the elements.
