  • Patent number: 8701976
    Abstract: A shipping container has a lid locked using pressure, rather than friction. The container includes front and rear side panels and a lid. The lid has a positive locking tab for engaging with a slot in the front side panel. The tab has a greater length than the slot. An end of the tab and an edge of the lid form a notch therebetween. In an embodiment, a corrugated paperboard blank is folded to approximate the lid to the front side panel. The lid is folded along an angled score line, rotating the tab with respect to the slot so that an end of the tab engages the slot and the front panel at an end of the slot engages the notch. The lid is folded to rotate the tab in the opposite direction; the tab then engages with the slot, the end of the tab extending beyond the slot.

  • Patent number: 5316207
    Abstract: A container formed by wrapping a slotted flexible sheet about rigid end panels having projections that extend through the slots. The projections include stacking projections which engage recesses in the end panels of adjacent stacked containers and support projections at the corners. The support projections engage each other when the containers are stacked to provide resistance to lateral loading. At least one end of the flexible sheet terminates in the top panel and engages a wedge-shaped projection on the end panels to lock that end of the sheet in place. The other end may be similarly locked in place or may overlap the first end and be held in place by a tab and slot arrangement. Alternatively, the other end portion of the sheet may include a lid which is held in place by mechanical tabs, while intermediate edges spaced from the end engage the wedge-shaped projections.
