Immobilizer tray for modular shipping container

A shipping container, comprising:

• an enclosure;
• and
• an adaptable immobilizer tray configured to be disposed within a cavity of the enclosure, the adaptable immobilizer tray being reconfigurable between a first configuration and a second configuration, the first configuration configured to secure a first payload, the second configuration configured to secure a second payload, the first payload being a different volume relative to the second payload, the adaptable immobilizer tray comprising:
• a base plate:
• a first sidewall extending vertically from a first side of the base plate;
• a second sidewall extending vertically from a second side of the base plate;
• and
• wherein:
• the first sidewall and the second sidewall each comprise a first slot spaced apart longitudinally from a second slot,
• the first slot and the second slot of the first sidewall and the second sidewall each comprise a vertical portion extending from a bottom end to a top end.

A method of using a shipping container, comprising:

• transitioning an adaptable immobilizer tray from a first configuration to a second configuration, the first configuration configured to receive a first payload;
• disposing a second payload in the adaptable immobilizer tray, the second payload having a smaller volume relative to the first payload;
• placing the adaptable immobilizer tray and the second payload in a cavity of the shipping container;
• disposing a dry ice container on the adaptable immobilizer tray, the dry ice container including dry ice disposed therein, the second payload restrained vertically between the dry ice container and the adaptable immobilizer tray;
• and
• closing the shipping container,
• wherein the adaptable immobilizer tray comprises:
• a base plate;
• a first sidewall extending vertically from a first side of the base plate;
• a second sidewall extending vertically from a second side of the base plate;
• and
• wherein:
• the first sidewall and the second sidewall each comprise a first slot spaced apart longitudinally from a second slot, and
• the first slot and the second slot of the first sidewall and the second sidewall each comprise a vertical portion extending from a bottom end to a top end.

An adaptable immobilizer tray, comprising:

• a base plate;
• a first sidewall extending vertically from a first side of the base plate;
• a second sidewall extending vertically from a second side of the base plate;
• and
• a moveable plate configured to transition from a first position adjacent to the base plate to a second position vertically spaced apart from the base plate,
• wherein:
• the first sidewall and the second sidewall each comprise a first slot spaced apart longitudinally from a second slot,
• the moveable plate is slidingly engaged with the first slot and the second slot of the first sidewall and the second sidewall,
• the first slot of the first sidewall is disposed laterally opposite the first slot of the second sidewall,
• the second slot of the first sidewall is disposed laterally opposite the second slot of the second sidewall, and
• the first slot and the second slot of the first sidewall and the second sidewall each comprise:
• a vertical portion extending from a bottom end to a top end, and
• a longitudinal portion extending from the top end to a longitudinal end spaced apart longitudinally from the top end.
