Patent number: 8210379Abstract: A collapsible container for containing goods, including a liquid and/or solid/liquid mixture, configured to be assembled and disassembled manually without the use of tools. The container includes a plurality of upright panels coupled to a base by their bottom portions. Each panel of a first type is flanked along its opposing upright edges by a pair of adjacent panels of a second type. Each of the edges of each of the panels is coupled by an edge joining assembly to one of the edges of one of the flanking panels. The assembly comprises a first elongated edge joining member having a longitudinal channel with alternating partially enclosed portions and substantially unenclosed portions and a second elongated edge joining member having longitudinally extending spaced apart locking members. Each unenclosed portion is configured to receive a locking member, which are slid longitudinally within the channel into an adjacent partially enclosed portion.Type: GrantFiled: April 25, 2008Date of Patent: July 3, 2012Assignee: Pacific Bin CorporationInventors: Robert H. Afflerbach, David E. Griffin, Vipin Kumar, Dustin Miller, John R. McKnight, Craig M. Watjen, Peter D. Wilson

Patent number: 8033410Abstract: A collapsible container for containing goods, including a liquid and/or solid/liquid mixture, configured to be assembled and disassembled manually without the use of tools. The container includes a plurality of upright panels coupled to a base by their bottom portions. The bottom portion of each panel has a relieved portion that extends into a corresponding groove formed in the base. The panels include panels of a first type and panels of a second type, with the relieved portion of the panels of the first type differing from the relieved portion of the panels of the second type. Each panel of the first type is flanked along its opposing upright edges by a pair of adjacent panels of the second type. Each of the edges of each of the panels is coupled by an edge joining assembly to one of the edges of one of the flanking panels.Type: GrantFiled: May 3, 2007Date of Patent: October 11, 2011Assignee: Pacific Bin CorporationInventors: Robert H. Afflerbach, David E. Griffin, Vipin Kumar, John R. McKnight, Dustin Miller, Craig M. Watjen, Peter D. Wilson
