Mounted in the cap 3 is a transverse conduit II, ent sizes. one end I2 of which serves as a relief outlet hav An object of the invention is to provide a faucet ing a relief valve 9 held closed to its seat I3 by attachment integral with' and forming the neck spring 8 when the mixed fluid outlet I4 is open or unrestricted. Depending from the transverse of the top of a container, to support the container from the faucet. conduit II is a suction tube I5 having a check valve I6 which opens t0 suction and closes when Another object is to provide the container top with a compressible neck adapted to be clamped 10 there is pressure in the suction tube I5. The on the faucet spout. upper end of suction tube I5 has an outlet I1 which is in the conduit I I, facing the outlet I4. Another objectl of the invention is to provide Between the suction tube I5 and the relief out the container neck with a sleeve washer to pre let I2 there arises from conduit Il a sleeve I8 vent leakage through the neck and to prevent the washer from working loose or blowing out under fluid pressure when th'e faucet attachment is in use. Another object of the invention is to restrain having internal screw threads I9 which engage the external threads 20 on a hollow thimble 2| which serves as an inlet. The cap 3 has integral therewith a neck 22 having a plurality of longi tudinal slots 23, here shown as four in number, expansion of an auxiliary sleeve washer or re ducer for a smaller size of faucet, by a cover for 20 whereby the neck 22 is flexible or compressible. Inside of the neck 22 and over the slots 23 lits a the container neck. rubber sleeve washer 24 having at its inner end For further details of the invention, reference an inwardly projecting flange 25 which rests may be made to the drawing, wherein: and nts on a flange 2B at the inner end of the Figure 1 is a vertical sectional view through a mixing device provided with the faucet attach 25 neck 22. Both the flanges 25 and 25 have cen tral apertures indicated at 21 through which the ment of this invention. thimble 2I projects.
