Safety bag, especially hygienic

摘要

The pouch, for use e.g. as a urinal, is made from a thin, transparent plastics material. It has an aperture (2) of appropriate dimensions, equipped with reinforcing elements (3b) to facilitate opening, and there are inner tubular elements (4,5). The transverse edges (4a,5a) of the inner tubular elements extend across the whole width of the pouch when in its closed and flat state. The inner tubular elements act as a non-return valve in the pouch, preventing any liquid inside it from spilling out.
