Example

[0019]FIG. 1 illustrates a preferred construction of a knocked-down-flat (“KDF”) container blank 100. The blank 100 is used to construct a rectangular shaped container, although other configurations are possible, such as a cube shape. In a general construction, blank 100 includes two side wall panels 106 and two end wall panels 107 connected to four top flaps and four bottom flaps, the boundaries of which are formed by vertical fold lines 77 and horizontal fold lines 120, 140. For reference purposes, the fold lines are depicted as broken lines in FIG. 1. As used herein, a fold line may be a thin band of a weaken region of material. The thin band can be a specific area on a blank formed by conventional manufacturing methods in the paperboard art. Nevertheless, the fold line may be simply a predetermined area for folding along a part of the blank without a weaken area. The KDF container may be constructed by securing together the edges of a blank including the aforementioned panels.

Abstract

A container blank is provided which forms a container having a pair of end wall panels defining access apertures therein and a pair of side wall panels. The container blank also includes a plurality of minor flaps adjacent to the end wall panels where at least one of the minor flaps includes a horizontal fold line across the midsection of the minor flap and at least one vertical fold line that runs generally perpendicular to the horizontal fold line and defines at least one folding tab member on one of the minor flap locking tabs. Further, the container blank also has a plurality of major flaps adjacent to the side wall panels, where at least one of the major flaps has a receiving slot for engagement with an associated locking tab. The resulting container provides strength for use in storage including food product storage.

Description

FIELD OF THE INVENTION [0001] The present invention is directed generally to a container constructed from a paperboard blank. More particularly, aspects of the present invention relate to a paperboard container that has increased strength for material handling. BACKGROUND OF THE INVENTION [0002] In the shipping and packaging industry, laminated containers are used for transporting dry materials and products. In general, laminated containers are constructed from corrugated fiberboard having adhesively bonded layers. These laminated containers are generally constructed initially from a paperboard blank. One type of laminated container is a field pack produce container. This type of produce container has short wall panels connected to short top flaps with slot openings for closing the container. An access hole is generally located in the upper portion of each end of the short wall panels to allow a person to grasp the container to easily move and transport the container and to allow a ...
