Also, expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.

[0038] The present invention is directed to provide a simple and effective child-resistant closure with twin locking. It focuses on closures openable or removable by the combination of two actions to be performed simultaneously e.g. in this case pushing and turning. The invention discloses the use of a plurality of locking ratchets in the angled and stepped form in both upper and inner cap. Further, it also has an additional provision of locking teeth to provide an additional locking feature to the inner and outer cap of the container.

[0039] In the present invention, the inner wall of the outer cap (1) is provided with abutment surfaces i.e. plurality of locking ratchets which are complementary to the locking ratchets of the inner cap (2) as shown in FIGS. 8(a)-8(b), when the outer cap (1) is rotated in the opposite direction, in the absence of an axial force on the outer cap in the direction of the inner cap, prevents the rotation of the inner cap.

[0042] In another embodiment of the present invention, the outer cap (1) comprises a plurality of serration (A) on the circumferential outer sidewall surface adapted to enhance the gripping of a user on the outer cap (1).

[0043] In another embodiment of the present invention, the outer cap comprises a lock ring (B) on the bottom circumferential periphery of the outer cap (1) adapted to align the outer cap (1) on top of the inner cap (2).

[0044] In another embodiment of the present invention, the inner cap (2) comprises a plurality of threads (03) and at least one wad retain ring (05) on the circumferential inner sidewall surface (01) adapted to grip and hold the hollow neck of the container without slipping downwards beyond a predetermined point on the hollow neck of the container.

[0045] Yet in another embodiment of the present invention, the locking ratchet (C) positioned on the circumferential inner sidewall surface (D) of the outer cap (1) are complementary to the locking ratchet (04) positioned on the circumferential outer sidewall surface (02) of the inner cap (2).
