Patent ID: 7819125

Claim:
Case for packaging a product, comprising: a first portion defining a first housing and an opening permitting access to the first housing, the opening facing in a first direction; a second portion pivotally coupled to the first portion via a pivot member so as to permit pivoting of the second portion with respect to the first portion about a pivot axis substantially parallel to said first direction, the second portion being pivotally movable with respect to the first portion between a closed position covering the opening and an open position; and an opening/closing mechanism comprising: a first projection extending from an outer surface of the first portion, and a second projection extending downwardly from an outer surface of the second portion, the second projection being configured to reversibly interlock with the first projection, a guidance arrangement configured so as to allow substantially only the pivotal movement of the second portion with respect to the first portion, the guidance arrangement being distinct from the pivot member, wherein at least part of the guidance arrangement is located on an outer lateral surface of the first portion, and a locking arrangement configured to reversibly lock the pivotal movement of the second portion with respect to the first portion in the closed position; wherein the second portion defines a second housing; wherein the case further comprises a closure member and a screw-fastening arrangement removably fastening the closure member to the second portion to close the second housing; and wherein the screw-fastening arrangement is configured such that a direction of rotation of the closure member, when unfastening the closure member from the second portion, is opposite to a direction in which the second portion is pivoted relative to the first portion to move from the closed position to the open position.
