The transfer bead 40 of container is a ring like structure concentric to the neck of bottle or container and plays an important role to provide snap-fit lock feature to the present invention.

[044] The material should have a certain level of flexibility to ensure optimal performance. Therefore, the present invention of cap is made up of polymers like variety of plastics, including polyethylene, polypropylene, and polystyrene, and/or like material.

[045] The base of protruded edge 60 is provided with slant and/or curved edge to promote an easy passing of protruded edge against transfer bead 40 at the time of closing of cap 100, wherein the slits 48 member promotes flexibility of protruded edges 60 to allow them moving away in case of interaction between protruded edge 60 and transfer bead 40 of container 200.

[046] FIG. 3B shows detail view CB of FIG. 3A, wherein one embodiment of protruded edge 60 is in lock position with transfer bead 40 of container 200.

[047] FIG. 4A is a cross-sectional view of frontal plane of cap 100 and container 200 in close configuration, wherein the tab 24 are in locked position with base body 42.

[048] The said cap 100 closes with snap-fit feature with the interaction between the protruded edge 60 of cap and transfer bead 40 of container 200, wherein an external push to the cap 100 is required to achieve this position either with hand or machine. Once the snap-fit position of cap 100 is achieved with container, it securely covers the mouth 52 of container in a leak proof manner.

[049] To remove this cap 100 from container 200, a hard pull is required. This pull of cap 100 requires enough pull force to restrict children to open it, and any rotation of the cap 100 in snap-fit position does not allow the opening of this securely closed container 200. [050] The present invention is a child resistant cap 100 that requires adult like manual dexterity to open. To remove this cap 100 from container 200; there is a requirement to press the tab 24 with hand and unscrew the cap 100 simultaneously. A straight push of cap 100 in the direction of container 200 is required to close this container 200 with cap 100. The information 20 includes a direction of use guide in present invention.

[051] This base body 42 in lock position with tab 24 acts according to single rigid member with projected means 26. And further rotation in unscrew direction exerts a strong mechanical pull to remove the protruded edge 60 of cap 100 out of transfer bead 40 of container.

[052] When the tabs 24 are pressed, the projected means 26 of tabs 24 engages with tread 32 member and acts like regular thread member; further unscrew rotation with pressed tabs 24 will move the tabs 24 towards the roof 50 of cap 100 and cause the open end 86 touch the barrier wall 38 of base body 42, wherein the holding means 36 holds the bolting means 34 and restricts the tab 24 to move away in outward direction. Thus, due to mechanical advantage, the further rotation will cause a heavier push force to the barrier wall 38 of base body 42 to release the snap-fit position of cap 100.

[053] The screw thread has a mechanical advantage due to its helical shape, which allows it to convert rotary motion into linear motion. This means that a small amount of force applied to the screw can generate a much larger force perpendicular to the screw axis, enabling it to lift heavier loads. Therefore, the strongly secured snap-fit close position of present invention of cap 100 can easily be released with present invention configuration.

[054] FIGS. 5 A and 5B respectively show the frontal sectioned view of top part includes alternative functional structural configuration of arm structure 28, wherein, the arm structure 28 is provided in slant, curve, straight, round and/or combination thereof with or without window 22, adapted to provide functional adjustability to the roof 50 with variable containers.

The roof 50 of this embodiment of cap 120 is provided with arm structure 28. The arm structure 28 further extended to connect with base body 42. The edge cuts 98 are provided to promote hinge movement of tab 24 upon external force. [056] Referring again to FIG. 6A, alternative embodiment of child resistant cap 120 adapted to securely close a container 200, wherein a roof 50 adapted to engage with mouth 52, an arm structure 28 hinged with roof 50 and base body 42 with optional edge cuts 94 and protruded edge 60 adapted to snap-fit with transfer bead of container. The structure includes arm structure 28 hinged at roof 50 and base body 42, wherein arm structure 28 acts as a linkage member, and base body acts like lever element 96. The push down action to said cap 120 adapted to engage the roof 50 with mouth 52, and moves the arm structure 28 away to push the protruded edge 60 member downward to make snap-fit joint with transfer bead 40. To open this embodiment of cap 120, the top squeeze or press in the direction of shown horizontal arrows is required, which would cause enough pull to protruded edge 60 to come out from snap-fit position. An optional fulcrum 88 member is provided at the internal surface 54 of cap to otherwise act the lever element 96 of base body 42 as mechanical beam with fulcrum, thus squeeze of top part of base body 42 will release the cap 120 while lifting the protruded edge 60.

[057] In short, to remove this cap 100 from container 200; requires pressing tab 24 while unscrewing the cap; projected means 26 engages with the thread 32 of container 200; turning the cap further moves the open end 86 of tab 24 upward, aligning it with barrier wall 38; as the tab moves, the bolting means 34 engages with holding means 36; this locking makes the tabs 24 with projected means 26 rigid; continued rotation of the cap exerts enough force to pull it off the container 200, opening the cap effortlessly.
