ABSTRACT:
The flexible bag comprises a container of flexible plastics material having an internal sheet and an external sheet which define a sealed chamber which can be filled with air at low pressure. The sealed chamber is composed of a series of tubes separated by welded seams but in communication with each other. The air causes the container to assume a substantially parallelepipedic external shape and produces an internal housing which is defined by the internal flexible sheet and which is capable of housing an office machine, for example a portable typewriter. The container comprises two handles projecting from the parallelepipedic shape, for facilitating transportation of the container itself, and a valve to permit the container to be inflated only when it is to be used for the protection or transportation of the machine. The container may be easily deflated and in that case can be re-folded on to itself in order substantially to reduce its bulk. In addition the container has an opening at a position corresponding to the two handles to permit the passage, therethrough of the machine, and two movable flap portions having closure means for closing the opening, which are disposed adjacent to the two handles.
