A container (1) includes a receptacle portion (3) and a lid (2) butt ends thereof being hingeably connected one to the other; one or more resiliently mounted teeth (4) are formed which extend upwardly from a forward end of the receptacle portion (3), and which include a body portion with a recess (5) extending therethrough; a plurality of laterally spaced apart protrusions (6) are provided and extend inwardly from a forward end of the lid (2), such that on the lid being hinged over the receptacle portion, the protrusions contact and move over the resiliently mounted teeth (4) so as to releasably engage within the recesses and so as to releasably lock the receptacle portion (3) and lid (2) together. Recess means (10) are provided and extend through an upper surface of the lid (2), adjacent a front face thereof, so as to allow for the insertion of release means (11) therethrough and between said one or more teeth (4) and a forward end of said lid (2) and into contact with a movable release bar (9) which acts to deflect the teeth (4) away from the front face of the lid, so as to allow for disengagement between said one or more teeth (4) and said one or more protrusions (6) and subsequent release of said lid (2) from said receptable portion (3).
