DETAILED DESCRIPTION OF THE INVENTION

(15) Turning now to the invention, there is shown in FIG. 1 a full side view of a device 1 of this invention. Shown is a housing 2, coaxially surrounding a vertical axis, said housing 2 having a top end 3 and a bottom end 4, both of which are open. The elongated hollow housing 2 has two, side-by-side open cavities 7 and 8, the full length of the housing (FIG. 5A). The first cavity 7 is larger in opening than the second cavity 8.

(16) There is a filter insert 9 which contains a filter media such as charcoal (not shown), or the like. Filter insert 9 is shown in FIG. 2. Filter insert 9 is hollow through its length, which is the same length as the elongated hollow housing 2, and is insertable into the open cavity 7 of the hollow housing 2 (shown in phantom in FIG. 4). The filter insert 9 has a bottom cap 10 integrally fitted therewith and the bottom cap 10 has two side by side openings through it, a larger through opening 11 and a smaller through opening 12. Through opening 11 has located in it a mesh or screen 13. The top of open cavity 7 has a mesh screen in it to retain any filter media contained in it.

(17) An adapter 14 is aligned and sits on the top end 3 of the elongated hollow housing 2. The adapter is shown in FIGS. 7A and 7B. This adapter 14 is manufactured from rubber or soft plastic and has two side-by-side openings 15 and 16. Opening 15 is the larger of the two openings, and is configured to be about the same size as the cavity 7 in the hollow housing 2. The smaller through opening 16 is designed to be about the same size as the cavity 8 of the elongated hollow housing 9. The smaller through opening 16 is fitted with a diaphragm 17 that acts as a reed valve when the device 1 is in use.

(18) The adapter 14 is fitted with a nozzle 18, the nozzle 18 shown in FIGS. 8A and 8B. In FIG. 8B, there is shown the internal configuration of the nozzle 18, in which there is shown a small through opening 19, that aligns with the adapter through opening 16, and a larger opening 20, that aligns with the through opening 15 of the adapter 14.

(19) In another embodiment of the invention the elongated housing 2 is fitted with a stopper 21 for use in bottles having a top opening. Such a stopper 21 is shown in FIG. 9A and a full bottom view of the stopper is shown in FIG. 9B. An opening 24 through the stopper 21 is shown in FIG. 9B. FIG. 9A shows ribs 22 that are concentric around a central core 23 of the stopper 21 to enable the stopper 21 to fit various size bottle openings. The stopper 21 is manufactured from rubber or soft plastic.

(20) The device of this invention can be manufactured from elastomers, rubbers, plastics or light metals, such as aluminum.
