The system contains a latch mechanism for a container having a first container portion and a second container portion comprising a guide part attached to the first container portion. A slide part is carried by the guide part, shiftable relative to the guide part between a closed position restraining the second container portion and an open position releasing the slide part from the second container portion. A guide catch part is integral with said guide part and a slide part including a depressible flap. A slide catch part is integral with said depressible flap. Interaction between said guide catch part and said slide catch part restrains said slide part against movement from said closed position into said open position. Actuating said depressible flap releases said slide catch part from being restrained by said guide catch part and frees the slide part to move from the closed to open position.
