Liquid container e.g. petrol tank, has blocking unit extending to both ends of hose in internal space and constricts hose cross section at its position such that cross section is smaller than outer perimeter of floating body at one position

摘要

The container has a hose (2) fixed at a connection nozzle (11), and a floating body (3) in an interior of the hose. The body is floatable in a fluid in the liquid container (1). The outer surface of the body is broken by openings, which are continuously connected with an opposite opening. A blocking unit (21) extends to both ends of the hose in the internal space, and constricts the hose cross section at its position such that the hose cross section is smaller than the outer perimeter of the floating body at a position.
