Combination container: A combination container is comprised of one or more inner containers within an outer container, and includes such common configurations as bottles within a box and cans within a box. Like single packaging, combination packaging must be tested as prepared for transport, but it's the assembly that's approved and not just the outer container as such. An outer container of a combination, like a UN 4G fiberboard box, is compliant only when packed with the number and design of inner containers with which it has been tested, or within the design variations permitted in the standard. It is not permitted to substitute inner containers of a more fragile material for those originally tested, to vary from the tested inner or outer container closure design, nor to alter the number of inner containers enclosed, without having those configurations covered by tests and included in the registered design.
Since the fiberboard boxes, plastic, glass or metal inner containers, as well as the various closures, usually come from different suppliers, it is the filler of combination style packaging that most commonly procures the container components and assembles the container for filling and transport. In that case Transport Canada would consider the filler of the container to be the container manufacturer of note and the design registration would be issued to them. Certain packaging supply houses do make available pre registered combination packaging in common configurations. Users of such pre registered combinations should request the packaging test report from the supplier. They must use the containers only with the components supplied and within the range of validity of the tests. Some inner container manufacturers have had tests conducted of their inners with typical outers and have been making the test reports available to their customers for use in registering their designs with Transport Canada. Users of those containers must take care to assemble the combination using only the specific components that had been tested.
Composite container: A container consisting of an outer packaging and an inner receptacle constructed so that the inner receptacle and the outer packaging form an integral container. Once assembled it remains thereafter an integrated single unit; it is filled, stored, shipped and emptied as such.
