Geometry Consideration
The volume occupied by the gas at the evaluation temperature, V1, will be called the "free gas
volume" of the package.
This volume can be

the contained material.
These volumes, which are illustrated in Figure B-1, can be represented as
V1 = Vc - Vm
[5]
and
Vc = Vo - vi - vcc
[5a]
where Vo is the interior volume of the outer container,
vi is the volume of the material of the inner container,
vcc is the volume of the materials making up the convenience container, and
Vm is the volume of the contained material.
B.2.2
Container Fill Gas
The appropriate equation for pressure as a function of temperature is simply the gas law:
PF = P0(V0/V1)(T1/T0).
