20220194652 · 2022-06-23 ·

A container comprising a bottom and a sidewall extending upwards from the bottom and terminating at an upper free edge, said upper free edge of the sidewall forming an opening of the container, said sidewall and said bottom comprising an outer paperboard layer and a thin inner plastic foil layer, formed in a thermoforming operation, said upper free edge of the sidewall comprising a rim portion extending past the outer surface of the paperboard layer of the sidewall. The rim portion comprises a rolled up portion of an upper portion of the outer paperboard layer of the sidewall, said rolled up portion being covered by a portion of the thin inner plastic foil layer. In this way, a stiff upper rim is provided, while allowing the use of a very thin inner plastic foil layer.

Container with insulating features

A container for containing a cold fluid. The container includes a sidewall construct that includes an inner sidewall extending at least partially around an interior of the container, an outer sleeve attached to the inner sidewall, and a cavity defined between the inner sidewall and the outer sleeve. The container also includes a closed bottom defining a bottom of the interior of the container, and insulating features that include the cavity and a plurality of annular bands, each annular band of the plurality of annular bands includes a spacer that extends in the cavity from the inner sidewall to the outer sleeve. Adjacent bands define a respective pocket of a plurality of pockets in the cavity such that the insulating features maintain a desired temperature of the cold fluid.
