Patent number: 6047523Abstract: A system for the vertical packaging of webbing rolls comprises a bottom tray, a top cap, a plurality of webbing rolls, and stretch wrap film. The bottom tray includes a bottom wall and a plurality of side walls extending upwardly from the bottom wall. Likewise, the top cap includes a top wall and a plurality of side walls extending downward from the top wall. The webbing rolls are positioned between the bottom tray and the top cap with the webbing rolls resting on the bottom wall of the bottom tray and the top cap positioned atop the webbing rolls. Horizontally adjacent ones of the webbing rolls are in contact with each other. The contact between adjacent ones of the webbing rolls helps to maintain the integrity of the system during movement thereof. To reduce the amount of packaging material utilized in the system, neither the bottom tray nor the top cap includes corners joining their respective side walls.Type: GrantFiled: March 18, 1998Date of Patent: April 11, 2000Assignee: Tenneco Packaging Inc.Inventors: Michael R.

Patent number: 6027327Abstract: An apparatus and method for forming thermoplastic containers having a male locking member. The apparatus includes a cavity defining a shape of the container, a stripper movable in a longitudinal direction relative to said cavity, and a retractable lock adjacent to an edge of the cavity. The retractable lock is movable in a transverse direction relative to the cavity between a retracted position and an unretracted position and movable in a longitudinal direction between a first position and a second position. The containers are formed through a process in which the apparatus is sequentially placed in a ready mode, lift mode, disengage mode, and back to the ready mode. In the ready mode, the retractable lock is placed in the unretracted position and first position in order to receive a sheet of plastic material and form a locking member thereon.Type: GrantFiled: December 30, 1997Date of Patent: February 22, 2000Assignee: Tenneco Packaging Inc.Inventor: Scott J.

Patent number: 6007470Abstract: A method is disclosed of folding a honeycomb panel, the panel preferably comprising a honeycomb core having opposing face sheets. A slit is preferably cut through one face sheet and the underlying honeycomb core and a wedge is driven into the honeycomb panel at the location of the slit. The wedge crushes the honeycomb core to a preselected depth with a preselected angle whereby the crushed honeycomb core forms a hinge. The honeycomb panel can then be folded along the hinge in a direction opposite the intact face sheet.Type: GrantFiled: October 23, 1997Date of Patent: December 28, 1999Assignee: Tenneco Packaging Inc.Inventors: Dale W.

Patent number: 5967663Abstract: A thermoplastic bag structure and method for making and packaging thermoplastic bags such that their tops are easily identified and the bags are easily opened. The method for producing these bags begins with cutting a flattened thermoplastic tube into two portions. At least one of the two portions is then collapsed to form a sheet of material having a pair of thermoplastic layers, a straight folded bottom edge and a pair of top edges, at least one of which has a skewed-cut. Bag side structures are formed in the sheet of material at about bag-width distances apart. The bags are then folded a predetermined number of times, in a direction transverse to the bag side structures, so that the skewed-cut top edge(s) of each of the bags remains exposed.Type: GrantFiled: August 22, 1997Date of Patent: October 19, 1999Assignee: Tenneco Packaging Inc.Inventors: Edward A.
