Claim 6

A container for storing separately two supply solutions having different specific gravities and for passiviely mixing the supply solutions into a single homogenous solution that is unstable over extended time periods, said container providing a positive check that a single homogenous solution has been achieved and comprising: a container wall; container dividing means spanning the interior defined by said container wall, said container dividing means and container wall defining an upper chamber and a lower chamber, one of the supply solutions carried in said upper chamber and the other of the supply solutions carried in said lower chamber; a top portion of said lower chamber disposed at the same elevation as a bottom portion of said upper chamber so that the top of said lower chamber is at an elevation higher than the bottom of said upper chamber; at least a section of said container wall being transparent to enable viewing of the interior defined by said top and bottom portions; two closure means mounted through said container dividing means for selective communication between said upper and lower chambers, one of said closure means mounted substantially vertically through said dividing means between said top portion of said lower chamber and said upper chamber, the other of said closure means mounted substantially vertically through said dividing means between said bottom portion of said upper chamber and said lower chamber; such that upon opening said closure means, solution transfer may be effected between said upper and lower chambers through at least one of said closure means until the solution level in each of said chambers is equal, the equal solution levels providing a positive indication that the two supply solutions have been mixed into a single homogenous solution within said container.

Claim 7

A container for storing separately two supply solutions having different specific gravities and for passively mixing the supply solutions into a single homogenous medical solution that is unstable over extended time periods, said container providing a positive check that a single homogenous medical solution has been achieved and comprising: a container wall including flexible plastic sheets; container dividing means spanning the interior defined by said container wall, said container dividing means and container wall defining an upper chamber and a lower chamber, one of the supply solutions carried in said upper chamber and the other of the supply solutions carried in said lower chamber; a top portion of said lower chamber disposed at the same elevation as a bottom portion of said upper chamber so that the top of said lower chamber is at an elevation higher than the bottom of said upper chamber; at least a section of said container wall being transparent to enable viewing of the interior defined by said top and bottom portions; two closure means mounted through said container dividing means for selective communication between said upper and lower chambers, one of said closure means mounted substantially vertically through said dividing means between said top portion of said lower chamber and said upper chamber, the other of said closure means mounted substantially vertically through said dividing means between said bottom portion of said upper chamber and said lower chamber, said closure means being opened by container-external manipulation of said container wall and closure means; such that upon opening said closure means, solution transfer may be effected between said upper and lower chambers through at least one of said closure means until the solution level in each of said chambers is equal, the equal solution levels providing a positive indication that the two supply solutions have been mixed into a single homogenous solution within said container.

Claim 8

A container for storing separately two supply solutions having different specific gravities and for passively mixing the supply solutions into a single homogenous medical solution that is unstable over extended time periods, said container providing a positive check that a single homogenous medical solution has been achieved and comprising: a container wall including flexible plastic sheets; container dividing means spanning the interior defined by said container wall, said container dividing means and container wall defining an upper chamber and a lower chamber, one of the supply solutions carried in said upper chamber and the other of the supply solutions carried in said lower chamber; a top portion of said lower chamber disposed at the same elevation as a bottom portion of said upper chamber so that the top of said lower chamber is at an elevation higher than the bottom of said upper chamber; at least a section of said container wall being transparent to enable viewing of the interior defined by said top and bottom portions; two closure means mounted through said container dividing means for selective communication between said upper and lower chambers, one of said closure means mounted substantially vertically through said dividing means between said top portion of said lower chamber and said upper chamber, the other of said closure means mounted substantially vertically through said dividing means between said bottom portion of said upper chamber and said lower chamber, said closure means being opened by container-external manipulation of said container wall and closure means; such that upon opening said closure means, solution transfer may be effected between said upper and lower chambers through at least one of said closure means until the solution level in each of said chambers is equal, the equal solution levels providing a positive indication that the two supply solutions have been mixed into a single homogenous solution within said container.
