PURPOSE: To take out simply an internal display element without breaking a container while making it repeatedly reusable by setting up a current introduction terminal, an exhaust hole and a vacuum valve on a bottomed box made of a non-magnetic metal while sealing a transparent glass cap on it with a sealing material.
CONSTITUTION: A container is formed by providing a bottomed box 11 made of non-magnetic stainless steel with a current introduction terminal 13 supplying current inside, an exhaust hole 14 used for exhausting the interior into a vacuum state and a vacuum valve 15 for opening and shutting said exhaust hole, while sealing an easily removable transparent glass cap 12 on it with a sealing material 16. Thereby, an internal picture display element 10 can be taken outside without damaging itself and breaking a container, thus making the container repeatedly reusable.
