Containers for collecting excretia for mutual disposal via a conventional lavatory are of laminated construction involving an internal layer of impermeable matl. fragile enough to be broken up by turbulence levels which prevail in a typical water flushed lavatory enclosed on each face by two layers of a matl. which will dissolve or disperse in water, pref. of polyoxyethylene or of polyvinylalcohol of which the outermost layer is 25-38 micron thick. The borders of the outermost layers extend beyond those of the intermediate layer so that in peripheral welded seams, each of the two outer layers becomes welded to the corresp. layer of the opposing wall of the container. More coherent and less permeable to handle under normal atmospheric conditions than similar containers of which the impermeable internal layer is a film of PVC and/or polyvinylidene chloride, of atatic polypropylene or of nitrocellulose, or is a coating of a grease, a silicone (oligomer) or a self-adhesive matl.
