Portable water cooler for use with bagged fluids and bagged fluids for use therewith

This is a portable cooler designed to hold a bag of liquid, keeping the fluid separate from the cooler's internal surfaces. An internal spike punctures the bag, allowing the liquid to flow through a pathway to an external spigot for dispensing. The cooler itself has a rigid, multi-layered body with at least one insulating layer.

Why it matters: Since 2006, the market for diverse consumer-grade bagged beverages has expanded significantly, making the multi-bag and thermal control features more relevant. Advances in compact cooling and insulation materials could also improve performance and cost-effectiveness.

Status: ExpiredProtection ended and was never renewed
How hard to build: ModerateLeak-proof spike and spigot mechanism.
