ABSTRACT:
A reusable thermally insulated box to deliver hot or cold food is provided which is simple to use, easy to construct, economical, and ecologically more beneficial than boxes previously available. The present invention is particularly directed to a reusable pizza box made of corrugated plastic board having sealed fluted edges and creased or indented un-perforated scored fold lines between adjacent panels instead of conventional scored lines having perforations. This provides a thermally insulated food delivery box that may be sanitized and made suitable for reuse.
