A container is described herein which uses three different types of restraining mechanisms to help secure glass sheets therein so that the glass sheets can be safely transported from one facility (e.g., a manufacturing facility) to a second facility (e.g., a customer facility). The first type of restraining mechanism includes two collapsible retainer bar mechanisms which are connected to one another by a support bar that can be moved so as to secure the major surfaces of the glass sheets. The second type of restraining mechanism includes two side restraints which are used to help secure the two opposing sides of the glass sheets. The third type of restraining mechanism includes two secondary retainer mechanisms each of which has a stopper that is moved to help secure/support the bottom portion of the glass sheets.
