A tab member for use in a latchable slidable package. The tab member has opposed major faces connected by opposed side edges and comprises a body portion and a cut out defining a resiliently deformable latch member connected to the body portion by at least one live hinge. The latch member incorporates a latch formation that is moveable by a user in an unlatching direction substantially orthogonal to at least one side edge. The tab member is substantially planar, and the unlatching direction lies substantially in a plane of the tab member. The tab member can be incorporated into a latchable slidable package to provide child resistance by virtue of the latch member and the latch formation. The substantially planar nature of the tab member means that the tab member can be easily accommodated in the package. Because the unlatching direction of the latch formation lies substantially in a plane of the tab member, the movement of the latch formation as the package is unlatched is substantially restricted to the same plane. Thus, the volume of the package that must be given to accommodate the tab member and the movement of the latch formations can be kept low, thereby reducing the overall size and weight of the package.
