A cap assembly for a container comprising: an outer cap having an outer cap end wall with an inner surface and an outer cap skirt with an inner surface, the outer cap having first end teeth that extend from the inner surface of the outer cap end wall, the outer cap having first vertical ratchet teeth on the inner surface of the outer cap skirt; and an inner cap (200, 700) having an inner cap end wall with an outer edge and an inner cap skirt joined to the outer edge of the inner cap end wall, the inner cap skirt having an inner surface with a thread, the outer cap overlying the inner cap and being concentric therewith, the inner cap end wall having an upper surface and second end teeth extending from the upper surface, the inner cap having second vertical ratchet teeth on an outer surface of the inner cap skirt, the thread selectively fastens the cap assembly on the container, wherein the first and second vertical ratchet teeth abut when the outer cap is turned in a direction to rotate the inner cap and the outer cap together to fasten the inner cap onto the container, wherein the upper surface of the inner cap end wall engages the inner surface of the outer cap end wall to form spaces in a vertical direction between the first and second end teeth, and wherein the first vertical ratchet teeth slide over the second vertical ratchet teeth when the outer cap is turned in a removal direction; and wherein when a downward force is applied on the outer cap, the second end teeth on the inner cap engage with the first end teeth on the outer cap to apply torque on the outer cap in the removal direction to turn the inner cap in the removal direction to release the cap assembly from the container, the inner cap having a tamper evident band connected to the inner cap skirt by a plurality of bridges, characterised in that the thread has a plurality of separations therein, the tamper evident band has a protrusion that fits in a cutout in the inner cap skirt when the tamper evident band is connected to the inner cap skirt, and each of bridges or protrusions are aligned with one separation in the thread. an outer cap having an outer cap end wall with an inner surface and an outer cap skirt with an inner surface, the outer cap having first end teeth that extend from the inner surface of the outer cap end wall, the outer cap having first vertical ratchet teeth on the inner surface of the outer cap skirt; and an inner cap (200, 700) having an inner cap end wall with an outer edge and an inner cap skirt joined to the outer edge of the inner cap end wall, the inner cap skirt having an inner surface with a thread, the outer cap overlying the inner cap and being concentric therewith, the inner cap end wall having an upper surface and second end teeth extending from the upper surface, the inner cap having second vertical ratchet teeth on an outer surface of the inner cap skirt, the thread selectively fastens the cap assembly on the container, wherein the first and second vertical ratchet teeth abut when the outer cap is turned in a direction to rotate the inner cap and the outer cap together to fasten the inner cap onto the container, wherein the upper surface of the inner cap end wall engages the inner surface of the outer cap end wall to form spaces in a vertical direction between the first and second end teeth, and wherein the first vertical ratchet teeth slide over the second vertical ratchet teeth when the outer cap is turned in a removal direction; and wherein when a downward force is applied on the outer cap, the second end teeth on the inner cap engage with the first end teeth on the outer cap to apply torque on the outer cap in the removal direction to turn the inner cap in the removal direction to release the cap assembly from the container, the inner cap having a tamper evident band connected to the inner cap skirt by a plurality of bridges, characterised in that the thread has a plurality of separations therein, the tamper evident band has a protrusion that fits in a cutout in the inner cap skirt when the tamper evident band is connected to the inner cap skirt, and each of bridges or protrusions are aligned with one separation in the thread.
