Pressure relief shipping adapter

A method of using a pressure relief shipping adapter, comprising:

• coupling the pressure relief shipping adapter to a bottle head assembly, wherein the bottle head assembly is coupled to a container containing a pressurized gas;
• reducing an internal pressure of the container by displacing a valve of the bottle head assembly into a valve depressor, the valve depressor disposed within an internal chamber defined by a body of the pressure relief shipping adapter;
• and
• discharging the pressurized gas from the container, through the body of the pressure relief shipping adapter, and out an outlet of the body.

A container pressure system, comprising:

• a bottle head assembly coupled to a container, wherein the container comprises a pressurized gas and the bottle head assembly comprises a valve;
• and
• a pressure relief shipping adapter coupled to the bottle head assembly, the pressure relief shipping adapter comprising:
• a body comprising a first portion, a transitional portion, and a second portion, wherein the transitional portion is disposed between the first portion and the second portion, wherein:
• the first portion comprises:
• a set of protrusions and a hole disposed through the set of protrusions;
• and
• an inlet disposed at a first end of the body;
• the second portion comprises an outlet disposed at a second end of the body, wherein the outlet is concentric with the inlet;
• an internal chamber within the body comprising a first section, a second section, and a third section, wherein the first section corresponds to the first portion of the body, wherein the second section corresponds to the transitional portion of the body, and wherein the third section corresponds to the second portion of the body;
• and
• a pressure relief valve disposed at the second end of the body and coupled to the outlet.
