A container (120) includes a closure device ( 121). The closure device includes interlocking fastening strips ( 130, 131) and a slider (132) slidably disposed on the fastening strips for facilitating the occlusion and deocclusion of the fastening strips. The slider (132) includes a top portion ( 140) and first and second side portions (142, 144). The slider additionally includes shoulders that merge into the first and second side portions and prevent the slider from being disengaged from the fastening strips. The slider includes long length front shoulders (150, 156) and long length rear shoulders (162, 164) in conjunction with shorter length front shoulders (152, 154) and shorter length rear shoulders (160, 166). If an upward force (180) is applied to the slider (132), the longer length shoulders are designed to remain engaged with the fastening strips when the side portions of the slider are forced to flex outward.
