I'm going to answer what I think is being asked here and not the specific question....
If the container has not been proven to be air-tight, a dog will still be able to smell the contents. Humans? Likely not, but, personally, if I can't guarantee the container's airtight or the bag has been vacuum sealed I wouldn't put myself in any risky situations with my paraphernalia or personal stash on my person.
[EDIT: Keep in mind that while airtight containers will keep odors contained therein, it's still highly likely to leave residual odors on the outside of the case and on your person. Those residual odors have proven to detectable by dogs in the past and have resulted in more thorough searches of a suspect or target of an investigation.]
