Abstract
A fibrous collapsible shipping container for transporting small articles and particulate material and discharging the same under gravity through a bottom wall opening after the horizontal movement of a sliding door. The container may include a liner element to provide increased rigidity where the loaded contents are relatively heavy. In a second embodiment, the container includes a second medially positioned bottom wall and sliding door to provide incremental discharge of the contents, as desired.
Claims6
In a collapsible fibrous container for use in transporting and dispensing particulate materials and molded articles, the container having vertical front, rear and side walls, and a bottom wall interconnected with said vertical walls to form a rectangular enclosure, the improvement comprising:
- said bottom wall having a through opening therein for the passage of contents of said container there-through, and a slidably mounted generally planar panel selectively overlying said opening for controlling the flow of said contents to said opening.
In a collapsible fibrous container for use in transporting and delivering particulate materials and molded articles, the container having vertical front, rear and side walls, and a bottom wall interconnected with said vertical walls to form a rectangular enclosure;
- said container having a removal cover with an integral peripheral side wall, and a foldable liner engaging the inner surfaces of said vertical walls, the improvement comprising:
- said cover being formed of double wall corrugated materials having flutes of varying width for each wall to provide increased rigidity;
- said liner being formed of corrugated triple wall material, with the corrugations being in mutually congruent relation to provide maximum supporting strength to said container while providing a convenient forming of fold lines.
