In order to infringe on a claim, your device must include each and every element of the claim.
Looking at the first claim:
A container for preservation, storage, tracking and transport of a controlled substance comprising:
(a) a one piece lower can portion containing a controlled substance;
(b) a one piece lid having a pop-top opening affixed to said lower can portion;
(c) a sealable plastic bag and an insert spacer
means for taking up empty space left within said lower can portion;
(d) means for identifying the controlled substance held within said
container; wherein the controlled substance is placed in said sealable
plastic bag and said sealable plastic bag is sealed before the
container is sealed.
If you don't implement the plastic bag, you are avoiding step 1(c) and 1(d) so presumably you would be OK with respect to infringement of this claim.
That said, freedom-to-operate evaluations can be tricky and there are potentially other patents that may be relevant. It is always best to obtain an actual legal opinion from a patent lawyer before proceeding.
