Locking Package

A package, comprising:

• a tray and a sleeve,
• wherein the sleeve comprises a front panel and a back panel connected by a plurality of side panels so as to form an inner cavity with an insertion opening, wherein the tray is insertable into the insertion opening and is slidable within the inner cavity between a closed position and an open position,
• wherein the plurality of side panels includes a side panel having a rear locking slot, and
• wherein the tray has extending therefrom a resiliently deflectable locking tab,
• wherein the locking tab and rear locking slot are shaped and positioned such that when the tray is seated in its closed position, the locking tab extends through the rear locking slot, whereby contact between a contact edge of the locking tab and a corresponding contact edge of the rear locking slot prevents movement of the tray out of its closed position towards the insertion opening,
• wherein the locking tab and the rear locking slot are further shaped and positioned such that the locking tab is downwardly deflectable to a position in which the contact edge of the locking tab is clear of the corresponding contact edge of the rear locking slot, thereby allowing the tray to be moved out of its closed position,
• wherein the sleeve is further provided with a resiliently deflectable release tab that is positioned such that, when the tray is in its closed position, the locking tab is releasable from the rear locking slot by downward deflection of the release tab.
