Abstract
Abstract One piece die-cut card- or corrugated board structure of the storage bin includes a bottom panel, two opposite side wall panels connected respectively to the lateral sides of the bottom panel along lateral score lines, a front wall panel connected to the front side of the bottom panel along the front score line, a front locking panel connected to the outer side of the front wall panel along intermediate front score lines, short front flap connected to a lower portion of the front side of each side wall panel along a short score line, elongated tuck flaps connected respectively at their short sides to each lateral side of the front locking panel along a score line and further including two equally spaced score lines extending parallel to the doubled score line, tuck slots provided in the front end portion of each side wall panel opposite the short front flap, front locking means including front lock tabs projecting from the outer side of the front locking panel; and front lock slots provided in the front end portion of the bottom panel to engage the front locking tabs. In the assembled condition the elongated tuck flaps pass through the tuck slots from inside to outside and the end portion of each tuck flap is inserted into the space resulting between the short front flap and the front panel.
