ABSTRACT:
A foldable tote box is formed by a one-pierce die-cut and scored board of corrugated material, especially corrugated plastic materials, that includes novel locking system so as to facilitate quick assembly of the box. The board includes a generally rectangular bottom panel, two pairs of side-wall panels to form the side-wall of the tote box, and ore or two pairs of filler beam panels connected to one of the pairs or both pairs of side-wall panels. Each side-wall panel having the filler beam panels includes a side wall section and a flap section, on which two insert locking tabs are formed at appropriate locations to be associated with corresponding fastening tabs located on the filler beam panels. Each of the filler beam panels can be folded to form a hollow support beam. The novel locking system comprises a pair of locking insert tabs is cut out in form of cutting lines on a flap-over section of each end wall panel, and capable of engaging with a pair of holding tabs that is formed, respectively, at predetermined locations on the corresponding filler beam panels, wherein each locking insert tab and a corresponding holding tab are oriented in the same direction when the box is assembled, and the locking insert tab is longer than the holding tab, while the holding tab is wider than the locking insert tab such that the insert tab can be inserted through an opening as the holding tab is pressed away from the filler beam panel during assembling of the box, and the holding tab can hold and lock the locking insert tab upon release of the pressing.
