Title:
CONTAINER
Document Type and Number:
Japanese Patent JP3234336
Kind Code:
B2
Abstract:
PURPOSE: To make partial pressures inside and outside a container uniform by causing a cover body sealing the container to partially separate, when a pressure inside the container becomes higher than a pressure outside the container, and by excluding gases in the container from a gap in which the cover body separates from the container.
CONSTITUTION: Recessed grooves 3 as exhaust grooves 3 are provided in several places of the flange 2 of a container body 1 and the flange 2 is sealed from above by a cover body film 7. Further, unsealed parts 5 are provided and the cover body film 7 covers the whole surface while coming into contact with a protrusion 6 existing in the inner periphery of the flange 2. Thus, when gases are generated in the container body 1 and the container body is pressurized, the cover body film 7 is lifted by an internal pressure, a space is generated between the flange 2 and the cover body film 7 and the gases escape from the space so that it is possible to prevent the generation of expansion and rupture of the container body 1.
