Paperboards having improved MD and CD bending stiffness by including a paperboard binder coalescing agent to cause starch paperboard binder to coat at least some of the paperboard fibers. Also a method for preparing these improved bending stiffness paperboards by combining with an untreated paperboard fiber stream a treated paperboard fiber stream where at least some/at least a portion of the paperboard fibers are coated with a starch paperboard binder due to the coalescing action of a paperboard binder coalescing agent.

An apparatus for folding box blanks (22) into completed boxes includes a feeding station (24) having a swing guide assembly (46) designed to provide an abutting surface which makes contact with flaps/panels (44) of the box blank as the box blank is feed from the feeding station into a folding station (28). The swing guide assembly can be synchronized with a feed assembly (34) which moves box blanks from a hopper assembly (26) to a first feed position (36). Actuating drives (50, 52) operating at different speeds can be used to move the box blanks from the feeding station to a first and second folding station (28, 30).

A one-piece container formed from a single unitary blank of corrugated paperboard has a bottom wall, opposed side walls and inwardly inclined opposed end walls. Stacking tabs project upwardly from the end walls and tab locks in the bottom wall receive the stacking tabs of a subjacent container when the containers are stacked on top of one another. A reinforcing corner post extends the full height of the container in each corner. The corner posts are formed by panels extending from opposite ends of the end walls, wherein the panels include a first panel foldably joined to an end of an associated end wall and adhered to an adjacent side wall, a second panel foldably joined to the first panel and extending diagonally across the corner, and a third panel foldably joined to the second panel and adhered to an adjacent side wall.

A box with a wheel assembly platform has a tow strap with a folded position stowed in a recess in the platform and an unfolded position accessible outside the box. In one embodiment, the strap is incorporated in a pre-assembled handle pack positioned in the recess. The strap may be retracted by a torsion spring, and may be coiled in the pack by use of a rotating fork. In one embodiment axles projecting from rollers are supported in recesses formed in the platform, and in another embodiment the axles are supported in notches in the bottom end of cylinders mounted in cutouts in the platform. In a further embodiment a box has hand holes in opposite walls with a spacer panel providing finger access behind the holes. The platform may have hinged panels. A thermo formed skin may be applied to the platform or constitute the platform.

The present invention is directed to a shipping and display tray having a bottom wall (18), a front wall (24), a back wall (22), and a pair of opposed side walls (20a, 21a) foldably joined with one another for holding different products (PI, P2, P3) contained therein in an upright position at a point of sale. The shipping and display tray comprising a one-piece shallow tray (10) having a plurality of different sizes of compartments (12a, 12b, 12c) each of which contains a different product size and count therein. Each of the plurality of different sizes of compartments includes an adjustable buffer (30a, 30b, 30c) configured to change the size of the compartment and to accommodate the different product size and count while maintaining a fixed perimeter or outside dimension of the one-piece shallow tray.

摘要:
An easy to carry lightweight carton for shipping and storing cut paper and for providing rapid and easy access to the paper when the carton is opened. The carton has a base portion and a lid pivotally attached to the base portion. A front wall of the carton may be pivoted down when the lid is pivoted up to facilitate access to the contents of the carton for ease of unloading of paper from the carton. A carry handle is built into the base portion to facilitate carrying of the carton. The carry handle position causes the center of gravity of the carton to be closer to a user's body when carrying the carton. The carton may be re-closed after it is opened.
