Containers for holding materials

Abstract

The invention provides for a container that may include a liquid-holding vessel and a skeleton shell supporting the liquid holding vessel. The liquid-holding vessel may comprise a flexible polymer or plastic material for preventing contact between a liquid stored in or dispensed from the container and the skeleton. The liquid-holding vessel and the closure may be formed from a minimal amount of polymer or plastic. The invention also provides for a connection of a liquid-holding vessel with a fitment to the skeleton shell using ultrasonic means. Further, a skeleton shell with mating features allowing the skeleton shell to be formed with smooth edges is provided.
