Patent number: 10138032Abstract: A fastener assembly disposed at a lateral edge of a container includes: a first fixing member, two second fixing members, and a retaining member. The second fixing members each includes a fixing seat which includes a pivot recess and a restricting recess, and a pivot ear which includes a pivot end and an engaging recess, and the pivot ends are pivoted in the pivot recesses. The retaining member includes two restricting ribs and two push ribs, the restricting ribs are restricted in the restricting recesses of the fixing seats, and the push ribs are pushed against the two pivot ears, so as to prevent the pivot ears from pivoting outward. In addition to being used as a lock on a single container to lock the upper and lower covers, the fastener assembly can also be used to assemble a plurality of containers together in desired patterns.Type: GrantFiled: November 9, 2015Date of Patent: November 27, 2018Inventor: Chi-Hsiung Chang
