Abstract
Abstract A portable water container for holding water treated by reverse osmosis water purification, which container rests on a base. The base has a recess in which a reverse osmosis unit is laid, with water connecting means for supplying water to the portable water container and for providing an overflow. The reverse osmosis unit can be quickly and easily removed from the base by merely lifting the osmosis unit from the recess and pulling stopper type end connectors from the ends thereof. The walls of the recessed portion of the base restrains movement of the stopper end connectors from the osmosis units during use. Also a unique reverse osmosis unit is used that has activated carbon impregnated paper therein through which the water passes providing further water treatment.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
172 words
A reverse osmosis water unit comprising: a portable water container for receiving and dispensing treated water, base means for supporting said water container, said base means having a recessed volume with end walls, reverse osmosis water treating means for being laid lengthwise in said recess between said spaced walls, water conduit means for conducting water to said reverse osmosis means and for conducting treated water from said reverse osmosis means to said water container, removable stopper type end connector means for connecting the ends of said reverse osmosis means to said water conduit means by a slip connection, sealing means for sealing the connection of said end connector means to said reverse osmosis means against water leakage, and the composite length of said reverse osmosis means and the connected end connector means being slightly less than the distance between said end walls of said base means, whereby said walls prevent outward sliding movement of said end connectors when said reverse osmosis means are positioned in the recess volume of said base means.
Claim 2
Dependent Claim
172 words
A reverse osmosis water unit comprising: a portable water container for receiving and dispensing treated water, base means for supporting said water container, said base means having a recessed volume with end walls, reverse osmosis water treating means for being laid lengthwise in said recess between said spaced walls, water conduit means for conducting water to said reverse osmosis means and for conducting treated water from said reverse osmosis means to said water container, removable stopper type end connector means for connecting the ends of said reverse osmosis means to said water conduit means by a slip connection, sealing means for sealing the connection of said end connector means to said reverse osmosis means against water leakage, and the composite length of said reverse osmosis means and the connected end connector means being slightly less than the distance between said end walls of said base means, whereby said walls prevent outward sliding movement of said end connectors when said reverse osmosis means are positioned in the recess volume of said base means.
Claim 3
Dependent Claim
40 words
A reverse osmosis water unit as claimed in claim 1 wherein: said reverse osmosis water treating means having ends with bores therein, and said removable stopper type end connectors comprising cylindrical plug members for being slidably inserted in the bores.
Claim 4
Dependent Claim
107 words
A reverse osmosis water unit as claimed in claim 2 including: O-ring means positioned between said cylindrical plugs and the inner surface of said bores providing said sealing means, internal channels through the ends of said reverse osmosis means that communicate with said bores and having a first internal diameter for conducting treated water passing from said reverse osmosis means to said water container, and the internal channel for conducting discharge brine water through the end of the reverse osmosis means to said conduit means having a substantially smaller internal diameter than said first internal diameter providing fluid back pressure on said reverse osmosis water treating means.
Claim 5
Dependent Claim
32 words
A reverse osmosis water treating unit as claimed in claim 3 wherein: said reverse osmosis water treating means comprising at least a pair of reverse osmosis water module means connected in parallel.
Claim 6
Dependent Claim
39 words
A reverse osmosis water unit as claimed in claim 1 wherein: said base means having inner spaced walls that are spaced from said end walls and which inner walls are shaped to receive and support the reverse osmosis means.
Claim 7
Dependent Claim
83 words
A reverse osmosis water unit as claimed in claim 5 wherein: one end of said container having an upper opening with an extended neck portion, cap means for fitting over said neck portion, said cap portion having first and second nozzle ends for being connected to said conduit means, and the lower one of said nozzle means being connected to the treated water discharge and the upper one of said nozzle means being connected to the conduit line leading to an overflow discharge.
Claim 8
Dependent Claim
47 words
A reverse osmosis water unit as claimed in claim 6, wherein: said base means having a vertical upwardly projecting enclosure member with three closed sides and a closed top with one open side for sliding over and enclosing said cap means and one end of said container.
Claim 9
Dependent Claim
35 words
A reverse osmosis water unit as claimed in claim 7 wherein: said portable water container at the opposite end of said cap means and at the lower side thereof having a water discharge spiggot means.
