Secure product container 10 has opposed closure shells 10P and 10A forming product chamber 10C. The shells may be separated into an open accessible state (see FIG. 1A), in which the closure shells are uncaptured and product 10G is accessible. The closure shells may be placed together in a closed state along closure interface 12C (see FIG. 1B), in which the closure shells are captured to enclose the product. A closure capture between the closure shells holds the shells in the closed state. Closure capture 26 has a secured condition (see FIG. 2B) in which the closure shells are captured together in the closed state, and a released condition (see FIG. 2A) in which the closure shells may be uncaptured in the accessible state. Capture release device 12 on active shell 10A is pressure responsive for releasing the closure capture from the secured condition into the released condition when pressurized. When depressurized, the release device permits the closure capture to be secure from the released condition into the secured condition. Pressure system 14 (shown in FIG. 1A) is in fluid communication with the release device for pressurizing the release device to release the closure capture and uncapture the closure shells. The pressure system also depressurizes the release device to permit securing the closure capture and capturing the closure shells.
