Document Type and Number:
Japanese Patent JPH0423238
Kind Code:
B2
Abstract:
A closure in the form of a wedge-shaped member (3) to close the end of a container, such as a transport flask. The wedge-shaped member (3) carries a seal plate (7) which is urged by spring means (9) to project beyond the smaller end of the wedge-shaped member when the latter is in a position to open the end of the container. On advancing the wedge-shaped member (3) to close the end of the container the projecting end of the plate (7) first abuts against a stop (18) and continued advance of the wedge-shaped member relative to the seal plate (7) causes displacement of the seal plate towards the interior of the container to effect a seal at the end of the container.
