<p><P>PROBLEM TO BE SOLVED: To solve the following problem: in a storage container including a storage part in which powder is stored and an aperture part which forms an aperture, powder is leaked from the storage part to the outside of the storage container by action of reducing internal pressure of the storage container when the internal pressure of the storage container rises from a state where the aperture is hermetically stopped up. <P>SOLUTION: A hermetically stopping member is biased toward the aperture part by a biasing means, whereby it covers the aperture part to obtain a hermetically stopped state where the aperture is hermetically stopped up. When the internal pressure of the storage container rises from the hermetically stopped state, the hermetically stopping member separates from the aperture part, thereby obtaining an open state where the internal pressure of the storage container is reduced. The aperture part includes a reservoir part in which the powder is stored in an area covered with the hermetically stopping member, thereby inhibiting the powder from being leaked from the storage part to the outside of the storage container in the open state. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
