A system (10, 10') for providing securement of a plurality of secure portable encasements comprising: one or more encasements each capable of engagement, inseparable interaction, and subsequent disengagement with a common docking unit (200, 520), at least one of the one or more encasements comprises a soft sided encasement body, the soft sided encasement body comprises a securable mouth opening configured to be closed and secured; and one or more common docking units (200, 520); wherein at least one of the one or more encasements has a secure engagement mechanism comprising an external securement mechanism and an internal securement mechanism, wherein the external securement mechanism comprises a male type securement mechanism, wherein at least one of the one or more common docking units (200, 520) comprises a female type securement mechanism, and wherein the inseparable interaction between any one of the plurality of encasements and at least one of the common docking units (200, 520) is engaged by the engagement of the male type securement mechanism into the female type securement mechanism; wherein the male type securement mechanism comprises a pin biased by a spring and configured to extend into the female type securement mechanism for inseparable interaction between the at least one of the one or more encasements and one of the one or more common docking units (200, 520), and configured to retract out of the female type securement mechanism for disengagement between the at least one of the one or more encasements and the at least one of the one or more common docking units (200, 520); wherein the male type securement mechanism further comprises a male engagement body, and wherein the pin and the spring of the male type securement mechanism are telescopically received in the male engagement body; wherein the male engagement body has aligned through slots; wherein the pin has aligned through slots aligned with the through slots on the male engagement body; wherein the external securement mechanism comprises a lever having a lever arm and a pivot, wherein the lever arm is configured to be inserted through the aligned through slots on the male engagement body and through the aligned through slots on the pin to retain and align the pin within the male engagement body; and wherein, when the male securement mechanism is secured in the female securement mechanism, the pin is configured to apply a force on the lever arm against the opposing force of the spring within the male engagement body to cause the inseparable interaction between the at least one of the one or more encasements and the one or more common docking units (200, 520). one or more encasements each capable of engagement, inseparable interaction, and subsequent disengagement with a common docking unit (200, 520), at least one of the one or more encasements comprises a soft sided encasement body, the soft sided encasement body comprises a securable mouth opening configured to be closed and secured; and one or more common docking units (200, 520); wherein at least one of the one or more encasements has a secure engagement mechanism comprising an external securement mechanism and an internal securement mechanism, wherein the external securement mechanism comprises a male type securement mechanism, wherein at least one of the one or more common docking units (200, 520) comprises a female type securement mechanism, and wherein the inseparable interaction between any one of the plurality of encasements and at least one of the common docking units (200, 520) is engaged by the engagement of the male type securement mechanism into the female type securement mechanism; wherein the male type securement mechanism comprises a pin biased by a spring and configured to extend into the female type securement mechanism for inseparable interaction between the at least one of the one or more encasements and one of the one or more common docking units (200, 520), and configured to retract out of the female type securement mechanism for disengagement between the at least one of the one or more encasements and the at least one of the one or more common docking units (200, 520); wherein the male type securement mechanism further comprises a male engagement body, and wherein the pin and the spring of the male type securement mechanism are telescopically received in the male engagement body; wherein the male engagement body has aligned through slots; wherein the pin has aligned through slots aligned with the through slots on the male engagement body; wherein the external securement mechanism comprises a lever having a lever arm and a pivot, wherein the lever arm is configured to be inserted through the aligned through slots on the male engagement body and through the aligned through slots on the pin to retain and align the pin within the male engagement body; and wherein, when the male securement mechanism is secured in the female securement mechanism, the pin is configured to apply a force on the lever arm against the opposing force of the spring within the male engagement body to cause the inseparable interaction between the at least one of the one or more encasements and the one or more common docking units (200, 520).
