1. Purpose of Establishing Criteria
Omitted2. Applicable Scope
The certification criteria shall apply to vacuum bottles for portable use, for table top
use and for lunch box and heat-retention cookers that have a vacuum heatinsulating structure. However, this shall exclude those using electricity, gas, oil, andother energy for heat/cold retention.
3. Terminology
Vacuum bottleBottle using a double-wall vacuum glass vessel as its
inner bottle being intended for table top use only, or bottle
using a double-wall vacuum stainless steel vessel as its
vessel for both portable and table top use as well as lunchcontainer.
Types of vacuum bottles follows JIS S2006 “Vacuumbottles”.

Heat-retention

Solid ingredients are put in a cooking pot and heated.

cookerHeating is stopped when adequate temperatures arereached, and then the food is transferred to a vacuum
double container made of stainless-steel. A heat-retention
cooker is designed to keep food warm and continue to cookwith remaining heat.

Capacity●Heat-retention cooker
Capacity when liquid fills the cooking pot to the edge
thereof, or actual capacity of the heat retaining container(in liters)

Expendable part
