A cap assembly can include an inner cap configured to couple to a container body and an outer cap coupled to the inner cap. A first coupler can be coupled to the inner cap and a second coupler can be coupled to the outer cap and configured to optionally engage the first coupler. An outer cap can be configured to rotate relative to an inner cap when the outer cap is in one or more positions and to engage the inner cap when the outer cap is in one or more other positions. A child resistant container can be made from recyclable metal. ## Claims ### Claim 1 A child resistant container, comprising: a container body having a central longitudinal axis, a closed base, an open top and an exterior wall; and a cap assembly configured to couple to the container body for closing the container; wherein the cap assembly comprises an inner cap configured to couple to the container body and an outer cap coupled to the inner cap, each of the inner and outer caps having a top; a first coupler coupled to the inner cap; and a second coupler coupled to the outer cap and configured to optionally engage the first coupler; wherein the inner cap is disposed at least partially within the outer cap; wherein at least a portion of the top of the outer cap is configured to optionally move among first and second positions relative to the inner cap along the central longitudinal axis, the first position being further away from the top of the inner cap than the second position; wherein the outer cap is configured to rotate relative to the inner cap when the top of the outer cap is in the first position; and wherein the second coupler is configured to engage the first coupler when the top of the outer cap is in the second position. ### Claim 2 (depends on 1) The container of claim 1, further comprising a plate disposed at least partially between the top of the inner cap and the top of the outer cap, wherein the second coupler is coupled to the plate. ### Claim 3 (depends on 2) The container of claim 2, wherein the plate is rotationally fixed relative to the outer cap. ### Claim 4 (depends on 1) The container of claim 1, wherein, when the top of the outer cap is in the second position, the outer cap is adapted to rotate relative to the inner cap before the second coupler engages the first coupler. ### Claim 5 (depends on 1) The container of claim 1, wherein at least a portion of the top of the outer cap is configured to elastically deform and the first position relative to the top of the inner cap is its rest position. ### Claim 6 (depends on 1) The container of claim 1, wherein at least a portion of the inner cap is retained within the outer cap by a radially inwardly rolled lip of the outer cap. ### Claim 7 (depends on 6) The container of claim 6, wherein the inner cap comprises a radially outwardly rolled lip and a height that is less than a height of the outer cap, and wherein the radially outwardly rolled lip of the inner cap is configured to at least optionally contact the radially inwardly rolled lip of the outer cap. ### Claim 8 (depends on 1) The container of claim 1, wherein the first coupler comprises a groove and the second coupler comprises a tongue configured to engage the groove. ### Claim 9 (depends on 1) The container of claim 1, wherein the first coupler comprises a plurality of grooves and the second coupler comprises a plurality of tongues configured to engage corresponding ones of the plurality of grooves. ### Claim 10 (depends on 1) The container of claim 1, wherein the first coupler comprises a plurality of grooves and the second coupler comprises a tongue adapted to engage two or more of the plurality of grooves. ### Claim 11 (depends on 1) The container of claim 1, wherein the first coupler comprises a plurality of grooves that extend radially outwardly from the central longitudinal axis. ### Claim 12 (depends on 11) The container of claim 11, wherein two or more of the plurality of grooves intersect. ### Claim 13 (depends on 11) The container of claim 11, wherein two or more of the plurality of grooves are at least partially perpendicular to one another. ### Claim 14 (depends on 1) The container of claim 1, wherein the first coupler comprises a groove having a rotationally leading side and a rotationally trailing side in a clockwise direction and the second coupler comprises a tongue having a rotationally leading side and a rotationally trailing side in a clockwise direction; wherein the leading side of the tongue is configured to engage the leading side of the groove for coupling the cap assembly to the container body; and wherein the trailing side of the tongue is configured to engage the trailing side of the groove for uncoupling the cap assembly from the container body. ### Claim 15 (depends on 14) The container of claim 14, wherein the leading sides of the tongue and groove are disposed at a first angle and the trailing sides of the tongue and groove are disposed at a second angle. ### Claim 16 (depends on 15) The container of claim 15, wherein the first and second angles are the same. ### Claim 17 (depends on 15) The container of claim 15, wherein the first and second angles are different. ### Claim 18 (depends on 15) The container of claim 15, wherein the first angle is 60 degrees relative to horizontal and the second angle is 65 degrees relative to horizontal. ### Claim 19 (depends on 15) The container of claim 15, wherein the groove is a first groove, wherein the first coupler further comprises a second groove, and wherein the second coupler is configured to skip out of the first groove and into the second groove when the cap assembly reaches a fully closed position. ### Claim 20 A child resistant container, comprising: a container body having a central longitudinal axis, a closed base, an open top and an exterior wall; and a cap assembly configured to couple to the container body for closing the container; wherein the cap assembly comprises an inner cap configured to couple to the container body and an outer cap coupled to the inner cap, each of the inner and outer caps having a top; a first coupler coupled to the inner cap, wherein the first coupler comprises a plurality of grooves that extend radially outwardly from the central longitudinal axis; and a second coupler coupled to the outer cap and configured to optionally engage the first coupler, wherein the second coupler comprises a plurality of tongues; wherein the inner cap is disposed at least partially within the outer cap and comprises a radially outwardly rolled lip that is retained within the outer cap by a radially inwardly rolled lip of the outer cap; wherein at least a portion of the top of the outer cap is configured to optionally move among first and second positions relative to the inner cap along the central longitudinal axis, the first position being further away from the top of the inner cap than the second position; wherein the outer cap is configured to rotate relative to the inner cap when the top of the outer cap is in the first position and the radially inwardly rolled lip of the outer cap is in contact with the radially outwardly rolled lip of the inner cap; and wherein the second coupler is configured to engage the first coupler when the top of the outer cap is in the second position.
