A portable, collapsible water tank suitable for use in combatting forest fires and the like that is manufactured from a flaccid synthetic material or a coated fabric which is capable of being ultrasonically welded. The bag is preferably made from a single sheet of material that is folded back upon itself to form a bag having uniformly sized front and rear panels. A filler assembly is mounted in the upper part of the front panel while a quick disconnect coupler is mounted in the lower part of the bag. The edge seams between the panel are welded closed using ultrasonic welding techniques. Radially extended skirts are provided about the bag outside of the seam areas and grommets are mounted within the skirts upon which shoulder straps and handles are either permanently removably secured. A hand-grip is welded to the front face of the tank beneath the filler assembly. The hand grip acts in conjunction with a handle attached to the top edge of the bag to allow the user to expand the tank to a fully opened position so that it can be rapidly filled to capacity.

A shut-off valve for a sprayer which includes an O-ring seal circumscribing the valve stem and serving the dual function of a packing seal between the stem and valve housing at all times as well as preventing fluid flow through the valve when the stem is in its closed position.

Shut-off valve for a sprayer

A nozzle which may be used with a low volume sprayer and which includes a plurality of spirally directed vanes positioned about a liquid inlet tube. Air is forced between the vanes creating a vortex which directs the liquid being expelled from the inlet tube against the vanes and then shears the liquid from the edges of the vanes in atomized form.
