ABSTRACT:
A composite structure is shown wherein a fibrous body or a tube such as a convolute or spirally wound paper tube or mold pulp bucket supports a plastic liner within the body to form a container. The material forming the mouth of the plastic liner is overlapped around at least one end of the supporting body and the outer overlapped layer of plastic is shrunk onto and around the outer side at the end of the support. In one form of the invention, the liner may be sealed at one end to form a bag suspended within the container to hold the product and caps may be applied to the open end or in the case of a tubular body, caps can be applied to the opposite ends of the body to complete the package. Prior to the sealing the mouth of the bag with a cap crimped onto the support body over the overlapped liner material, if appropriate, the contents of the bag may be subjected to a vacuum or a pressurized condition may be established within the container to hold the contents under the most appropriate conditions for storage. In another form of the container, after the liner has been put in its place, the outside of the composite structure can be surrounded by a resin tube that is then shrunk in place over the outer surface of the filled paper tube and its capped ends to prestress the paper tube with a compressive force.
Another aspect of the invention includes the mounting of a bail handle on means carried by the paper wall of the container, the can being adapted to contain a liquid such as paint. The plastic inner liner serves as a barrier layer to protect the paper support from penetration by the liquid and seals the bail mounting against leakage from inside the can.
