A closure system for a fluid container includes the cap, and a lip attached to a fluid container that is engaged by the latches of the cap. The lip may be integral with a fluid container or part of an adapter that is connected to the fluid container. A method of automated handling of a container includes engaging an annular groove of an actuator ring of a cap using a robotic arm, driving the actuator ring, and removing the cap from the container. The method may further include transporting the container via engagement of the robotic arm with the cap. ## Claims ### Claim 1 A cap for a fluid container, comprising: a main body having a cylindrical body portion including a plurality of latches, the plurality of latches having a release state and a secure state, the plurality of latches configured to be in the release state when a portion of each of the plurality of latches are depressed; and an actuator ring disposed over the cylindrical body portion of the main body, the actuator ring including: an annular groove formed in an outer surface of the actuator ring defining an exterior of the cap, the annular groove configured to receive and be engaged by a portion of an automated materials handling system, wherein the annular groove is parallel to a top of the main body and a bottom of the main body; and an actuation surface disposed on an inner side of the actuator ring, wherein, in operation, the actuator ring slides along cylindrical body portion of the main body from at least a first position wherein the actuation surface does not depress the portion of each of the plurality of latches to a second position wherein the actuation surface depresses the portion of each of the plurality of latches and the plurality of latches are in the release state. ### Claim 2 (depends on 1) The cap of claim 1, wherein the plurality of latches each include a spring configured to hold each latch in the secure state. ### Claim 3 (depends on 1) The cap of claim 1, wherein the plurality of latches each include a resilient material configured to hold each latch in the secure state. ### Claim 4 (depends on 1) The cap of claim 1, wherein the main body includes at least one of polyether ether ketone or aluminum. ### Claim 5 (depends on 1) The cap of claim 1, further comprising a close-range communication tag. ### Claim 6 (depends on 1) The cap of claim 1, wherein the main body further comprises at least one aperture through which fluid may pass into or out of the container. ### Claim 7 (depends on 1) The cap of claim 1, wherein a portion of the main body has an outer diameter smaller than an inner diameter of the actuator ring. ### Claim 8 A closure system for a fluid container, comprising: a lip attached to the fluid container, and a cap, the cap including: a main body having a cylindrical body portion including a plurality of latches, each of the plurality of latches having a release state and a secure state, each of the plurality of latches configured to be in the release state when a portion of each of the plurality of latches are depressed; and an actuator ring slidably disposed over the cylindrical boy portion of the main body, the actuator ring including: an annular groove formed in an outer surface of the actuator ring defining an exterior of the cap, the annular groove configured to receive and be engaged by a portion of an automated materials handling system, wherein the annular groove is parallel to a top of the main body and a bottom of the main body; and an actuation surface disposed on an inner side of the actuator ring, wherein in operation the actuator ring slides along the main body from at least a first position wherein the actuation surface does not depress the portion of each of the latches to a second position wherein the actuation surface depresses the portion of each of the latches and the latches are in the release state, and wherein the plurality of latches engage the lip when in the secure state. ### Claim 9 (depends on 8) The closure system of claim 8, wherein the main body includes a wall extending from a side facing the fluid container towards the fluid container, wherein the wall is configured to fit over the lip when the cap is installed on the container. ### Claim 10 (depends on 9) The closure system of claim 9, wherein the lip is attached to the container via a threaded connector. ### Claim 11 (depends on 10) The closure system of claim 10, wherein the threaded connector comprises a breakable seal configured to seal the contents of the fluid container. ### Claim 12 (depends on 11) The closure system of claim 11, wherein a portion of the main body abuts the seal when the plurality of latches engages the lip. ### Claim 13 (depends on 9) The closure system of claim 9, wherein the lip is formed integrally with the container. ### Claim 14 (depends on 9) The closure system of claim 9, wherein engagement of the plurality of latches with the lip when in the secure state is rotation-agnostic. ### Claim 15 (depends on 9) The closure system of claim 9, wherein the cap further comprises a pressure lock, the pressure lock including: an inlet configured to receive a pressure from an inside of the fluid container; and a locking member, configured to protrude from the pressure lock into a path over which the actuator ring is slidable along the main body when the pressure received from the inside of the fluid container exceeds a predetermined amount of pressure.
