Provided are a salvage container and a salvaging method capable of salvaging ammunition dumped into the sea using a simple configuration while more reliably suppressing the leakage of a chemical agent from the ammunition. A salvage container includes: a container body (); a lid () that blocks an opening portion of the container body (); a gasket () that is formed of a compressively deformable member and that blocks a gap between an inner side surface () of the container body () and the lid () from the outer side in a specific direction; and a gasket presser () that clamps the gasket () between the gasket presser () and the lid (). The container body () includes: a lid holder () that holds the lid () so that the lid () is displaced toward the outer side in the specific direction in relation to the container body (); and a gasket presser holder () that holds the gasket presser () so that the lid () is displaced toward the outer side in the specific direction in relation to the gasket presser () according to a decrease in the hydraulic pressure. The gasket () is compressively deformed by the relative displacement of the lid () so that the gap between the inner side surface () of the container body () and the lid () is hermetically sealed.

Salvage container and salvaging method

It is intended to provide a pressure container which can prevent dispersion of a hazardous substance or the like to the exterior and ensure a high level of safety with a simple structure. To achieve this object, a pressure container () comprises an outer vessel () and an inner vessel () which receives an impact load produced at the time of blasting disposal operation. The inner vessel () is disposed inside the outer vessel (). The inner vessel () has a pressure relieving part () which can discharge part of high-pressure gas produced in the inner vessel () at the time of the blasting disposal operation into a gap formed between the inner vessel () and the outer vessel ().

Pressure container

An object of the present invention is to improve durability of a pressure vessel for blasting an article to be treated such as hazardous substance or explosive therein. The pressure vessel, means for achieving the object, has an external vesseland an internal vesselinstalled in the external vessel. The external vesselhas a strength for retaining pressure caused by blasting the article. The internal vesselreceives fragments of the treated articleto protect the external vesselagainst the fragments. The internal vesselpreferably covers almost entire internal surface of the external vessel
