A container closure comprising a cap (2, 20) having a skirt (4) of substantially rectangular cross-section. Disposed in a central location of each internal surface (5) of the skirt are substantially coplanar rim-engagi ng members (96, 26). The container (3) has a neck portion (12) terminating in a n outer peripheral rim (8) surrounding an oval-shaped opening (7) in one end o f the container. Cap-engaging portions (9) on the outer portion of the peripheral rim engage with the rim-engaging members disposed on the skirt internal surface when the cap is in a closed position over the container opening. The rim-engaging members can be in the form of small ridges (60) or grooves (26) and can engage with cap-engaging portions formed by small ribs (9). Alternatively, when in the form of small ridges, rim-engaging members c an engage with cap-engaging portions in the form of a small edge extension arou nd the outer portion of the peripheral rim. The cap may be placed into a closed position on the container by aligning the edge of the skirt with a similarly configured edge of the container body and "snapping" the rim-engaging member s on the skirt into an engaged relationship with the cap-engaging portions on the peripheral rim. Twisting the cap slightly with respect to a vertical axi s of the container disengages the rim-engaging members and the cap-engaging portions to release the cap to an open position for removal from the contain er.
