Abstract: A family protective shelter which can be erected quickly inside in a home living room, family room, patio, or on an outside lawn area. This dome tent enclosure is designed of clear plastic sheet material which is impervious to gases used to conduct chemical warfare (such as nerve gas, mustard gas, serin, cyanide, and the like) dispersed biohazard aerosol compounds (such as anthrax, smallpox, polio, bacteria, viruses, or fungi), or other atmospheric toxins, such as those from a nuclear fallout. This protective “pop-up”, external frame enclosure will be sized to house at least two adults comfortably (6×9×7 high inside, up to about 10×18?×7? high), will incorporate a zip-lock entrance/egress isolation portal chamber, and will communicate to the outside world through combat gas mask filters, plus phone, computer and electrical outlet feed-through, and perhaps a water trap coupling.

Abstract: Sheets of flexible, compliant polymer film are sealed together along common, bottom and side edges thereof, to define a bag with an open top, and the upper portion of the bag has a dual thickness. The latter, dual thickness defines a hem, and the hem has a channel formed therein in which are confined draw ribbons or ties, the ends of the ties are fixed to sides of the bag. Apertures formed in the sheets provide access to the ties, in order that the same can be drawn taut, severed, and formed into bows.
