Abstract
A system for heat-shrinking a film onto an open-topped container is provided, including at least one reflective cup having a reflective interior surface, and at least one radiant energy source. The reflective cup and the radiant energy source may be rotationally mounted. The interior surface of the reflective cup has as least an elliptical portion and a parabolic portion.

A system for heat-shrinking a film onto an open-topped container including:
- at least one reflective cup having a reflective interior surface;
- and
- at least one radiant energy source, the at least one reflective cup and the at least one radiant energy source being rotationally mounted to allow the at least one reflective cup to rotate around a central axis while simultaneously directing radiant energy from the at least one radiant energy source toward the central axis,
- wherein the interior surface of the reflective cup has at least an elliptical portion and a parabolic portion.
A system for heat-shrinking a film onto an open-topped container including:
- a modular rotational assembly, the modular rotational assembly including at least one reflective cup having a reflective interior surface, and at least one radiant energy source,
- wherein the interior surface of the at least one reflective cup has at least an elliptical portion and a parabolic portion, and
- wherein the at least one reflective cup and the at least one radiant energy source are rotationally mounted to allow the at least one reflective cup to rotate around a central axis while simultaneously directing radiant energy from the at least one radiant energy source toward the central axis.
A system for heat-shrinking a film onto an open-topped container including at least one reflective cup having a reflective interior surface wherein the interior surface of the at least one reflective cup has as least an elliptical portion and a parabolic portion, and
- wherein the at least one reflective cup is mounted to allow the at least one reflective cup to rotate around a central axis while simultaneously allowing the reflective interior surface to face the central axis.
