PROBLEM TO BE SOLVED: To sell drinking water whose quality management is fully attentive for securing 100% recycle of a drinking water vessel in a long term, and for constructing a recycling-oriented society bringing about benefits to a whole society such as consumers, enterprises and local governments.SOLUTION: A drinking water vessel has a function such as the cold insulation maintenance device loaded with a temperature/level measurement device with IC tag capable of transmission/reception, and quality management is achieved on the basis of the temperature change of the drinking water in the vessel and the lapse of time. Thus, the adoption of a high-performance barrel-shaped cold insulation vessel for cold insulation makes it possible to solve the problem. |
