Latchable packaging

Abstract

A package including a support for supporting items, a primary structure for selectively blocking access to the items, and a secondary structure for covering at least some of the primary structure. The support is movable from a first position, whereat the primary structure blocks access to the items, to a second position, whereat the items are accessible. The support and primary structures comprise latch features designed to engage when the support and primary structures are in the first position to prevent movement of the support in the opening direction, and to disengage on moving at least one latch feature in an unlatching direction to accommodate movement of the support from the first position. The secondary structure comprises a disengagement region that cooperates with the latch features when the support and primary structure are in the first position to disengage the latch features.

         33 . A latchable package as claimed in  claim 26 , wherein the secondary structure has a thickness of between 0.1 mm and 2 mm. 
     
     
         34 . A latchable package as claimed in  claim 26 , wherein a front end of the secondary structure is substantially aligned with a front end of the primary structure when the support and the primary structure are arranged in the first position, and/or wherein a rear end of secondary structure is substantially aligned with a rear end of the primary structure when the support and the primary structure are arranged in the first position. 
     
     
         35 . A latchable package as claimed in  claim 26 , wherein the secondary structure has self-supporting rigidity. 
     
     
         36 . A latchable package as claimed in  claim 26 , wherein the support comprises a first stop feature configured to limit further movement of the support in the opening direction from the second position, and/or a second stop feature to limit movement of the support in a direction opposite the opening direction from the first position. 
     
     
         37 . A latchable package as claimed in  claim 26 , wherein the secondary structure is adhered to the primary structure. 
     
     
         38 . A latchable package as claimed in  claim 37 , wherein the secondary structure is coupled to the primary structure by a coupling flap. 
     
     
         39 . A latchable package as claimed in  claim 26 , wherein the internal dimensions of the secondary structure are substantially the same as the corresponding external dimensions of the primary structure. 
     
     
         40 . A latchable package as claimed in  claim 26 , wherein the secondary structure surrounds the primary structure in a close fit to provide a frictional engagement between the primary structure and the secondary structure.
