A machine for manufacturing disposable cups, including a side element, obtained from a blank of sheet material folded into a conical shape and sealed by a bottom element of circular shape, including a forming wheel rotatable with continuous motion. The forming wheel has a plurality of peripherally distributed forming assemblies including respectively a mandrel of tubular form carried by a support member swinging around an axis parallel to said axis of rotation of the forming wheel. First feeding means is adapted to orderly collect and insert single bottom elements into corresponding forming assemblies of the forming wheel. Second feeding means is adapted to collect single blanks in an orderly manner from a store in which the blanks are stacked and to transfer them in sequence, in an extended configuration, to the corresponding forming assemblies of said forming wheel.

A system, apparatus, process, or machine for forming a container for containing a 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 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 fluid.

Disclosed are a container for containing a cold or hot fluid and methods of forming said container. The container includes a sidewall construct including an inner sidewall extending at least partially around an interior of the container, an outer sleeve attached to the inner sidewall, and an air gap defined between the inner sidewall and outer sleeve. The width of the air gap is defined by a plurality of adhesive layers applied as successive annular beads to the inner sidewall. Methods can be employed to maximize the bead height of at least one of the adhesive layers to form the desired width of the air gap while maintaining adhesion properties and minimizing the amount of adhesive material used. Bead height for each layer can be optimized by controlling the type of adhesive material used, the application rate and temperature, the application angle, the cooling rate, and the dwell time.
