Claim:
A safe packaging container comprising: a blister sheet having a plurality of recesses concavely disposed thereon for loading contents; a back film, bounded on the planar surface of the blister sheet so as to cover the contents loaded in the recesses; an overlaying cover coupled to a first edge of the blister sheet and structured to fold over the blister sheet to cover the bounded back film, the overlaying cover having a throughhole defined therein; a fixing element disposed on a second edge of the blister sheet opposing the first edge, the fixing element structured to releasably couple to the through-hole to secure the overlaying cover to the blister sheet, wherein the overlaying cover hides the back film under the condition that the overlaying cover is secured to the blister sheet by the fixing element, and wherein the fixing element comprises a groove between latches, wherein an outer perimeter of the latches in a resting position is larger than an inner diameter of the throughhole, the latches being structured to flex from the resting position toward the groove to an inward flexed position so as to fit through the through-hole, the latches also being structured to release back to the resting position once placed through the through-hole, the latches securing the overlaying cover to the blister sheet in the resting position; and a fixing latch member that is structured to be placed within the groove of the fixing element after the fixing element has secured the overlaying cover to the blister sheet, the fixing latch member being configured to prevent the latches from flexing inward.
