Abstract: A breach filling apparatus for plugging a hole in a wall that includes an air supply assembly, a converting assembly connected to the air supply assembly for converting air pressure to lineal movement, a component storage assembly for storing fluid components of a foaming material therein and expelling the components upon lineal movement by the converting assembly, and a plugging assembly for plugging a hole through a wall structure. The plugging assembly comprises an inflatable flexible bladder having an outer wall defining an interior space for receiving the fluid components and expanding in size from a collapsed condition to an expanded condition. The plugging assembly has a mixing tube in fluid communication with the storage assembly and extends into the interior space of the flexible bladder with a plurality of apertures for expelling the components into the interior space of the flexible bladder.

Abstract: A new breach filling device for plugging a hole in a structure, such as, for example, a boat. The inventive device includes a container having a plurality of reservoirs therein for holding components of a foaming material in the reservoirs. A flexible inflatable bladder has an interior space. A conduit system is for fluidly connecting the reservoirs of the container with the interior space of the inflatable bladder. The conduit system is designed to convey the components of the foaming material separately between the container and the inflatable bladder. The conduit system is designed to discharge the components into the interior space of the bladder such that mixing of the components occurs in the interior space and the foaming material forms a foamed material in the interior space for inflating the inflatable bladder.

Abstract: A new breach filling device for plugging a hole in a structure, in particular, in a boat. The inventive device includes a container having a reservoir for holding a foaming material therein and a flexible inflatable bladder having an interior space. The interior space of the inflatable bladder is in fluid communication with the reservoir of the container to permit passage of foaming material from the reservoir of the container into interior space of the inflatable bladder. The foaming material forms a foamed material in the interior space of the inflatable bladder such that the foamed material inflates the inflatable bladder.
