Various embodiments of the apparatus and methods are configured to make containers such as disposable reinforced cups using reinforcing members configured to be respectively attached to cups. The apparatus and method of various embodiments of the present disclosure sequentially heat different or selective portions of the heat activated adhesive on the reinforcing member at multiple sequential stages, steps or times to attach the reinforcing member to the container.

Apparatus and method for manufacturing reinforced containers

A reinforced plastic foam cup including a body which defines an open top end and a closed bottom end, wherein the top end has a greater diameter than the bottom end. The body includes a reinforced tapered side wall that extends from the bottom end to the top end. A substantial portion of the reinforced tapered side wall includes a plastic foam layer, a pressure sensitive adhesive layer and a rigid material layer. Such reinforced plastic foam cup provides an improved tactile feel and enhanced insulation and rigidity properties.
