Claims.

This invention relates to an improved container for carbonated liquids and seeks, among other objects, to provide a device of this character which will be simple, efficient and inexpensive.

A further object of the invention is to provide a device embodying improved valve mechanism for liberating the carbonated liquid and wherein the cap of the device will be so formed as to protect the valve stem against accidental injury.

io Another object of the invention is to provide a device wherein, when the valve is open, the fluid will be directed to the outlet nozzle of the cap and will be prevented from escaping past the upper end of the valve stem.

lo Arid the invention seeks, as a still further object, to provide an improved nozzle which will emit a fine spray or vapor.

Other and incidental objects of the invention not specifically mentioned in the foregoing will be •2o apparent during the course of the following description.

In the accompanying drawing,

Figure 1 is a vertical sectional view of my improved container, and

Figure 2 is a top plan view of the cap.

In carrying the invention into effect, I employ a vessel 10 which may be a bottle of glass or other approved material, the vessel being provided at its upper end with a neck 11 having external so threads. The vessel may, of course, be of any desired capacity, and, in the present instance, I have shown the vessel as of cylindrical shape.

Detachably connected to the vessel 10 is a cap 12 which is preferably of bakelite, although other 35 suitable material may be substituted in lieu thereof. The body of the cap is formed at its lower side with an internally threaded annular flange 13 which is screwed upon the neck 11 of the vessel 10 for detachably connecting the cap 40 thereto and disposed within said flange is a gasket 14 of rubber or other suitable material which provides a sealed joint between the vessel and the cap. Depending axially from the cap body at its lower side is an outlet nipple 15 integral 45 with the cap and formed in the lower end of the nipple is a tapered valve seat 15'.

Above the nipple 15, the body of the cap is cylindrically recessed, as at 16, and surrounding said recess is an upstanding annular flange 17, the 50 body being .externally stepped. Rising from the bottom wall of the recess 16 is a boss 18 in the upper end of which is provided a recess 19 concentric with the axis of the nipple 15 and formed laterally through said boss is a discharge passage 55 20 communicating with the upper end of the pas(Cl. 299—95) sage through the nipple. Concentric with the passage 20, the body of the cap is formed at its adjacent side with an annular boss 21 having a flat outer face and opening through said boss is a recess 22 communicating with said passage, the 5 recess being internally screw threaded.

Screwed at its inner end into the recess 22 is an atomizing nozzle 23 having an annular flange 24 seating flat against the fiat face of the boss 21 and formed in said nozzle is a smooth discharge 10 passage 25 having a rounded outer end. Communicating with the rounded outer end of the passage 25 is a discharge orifice 26 relatively minute in relation to the diameter of the passage 25 and loosely and slidably fitting in said passage 15 is an atomizing screw 27.

Frictionally but removably fitting at its upper end over the nipple 15 is an outlet tube 28 which may be of glass or other suitable material. This tube projects to a point near the bottom of the 20 vessel 10 and extending through the boss 18 and through said nipple, axially of the latter, is the stem 29 of the outlet valve of the device. This stem is of a diameter considerably less than the diameter of the nipple so that a liquid may flow 25 through the nipple around the stem and fixed to the lower end of the stem is a preferably rubber valve disk 30 fitting the valve seat 15'. Snugly but slidably surrounding the valve stem to rest flat against the bottom of the recess 19 is a pref- 30 erably rubber gasket 31 which fits more or less tightly within the recess and resting at its lower end against the gasket is a spring 32 surrounding the upper end portion of the stem. Fixed upon the upper terminal of the stem is a cylindrical 35 head or button ,33 which more or less closely but slidably fits within the flange 17 of the cap and forms an abutment for the upper end of said spring. This head is, at all times, disposed within the lines of the flange 17 so as to be housed and 40 protected thereby.

Assuming the vessel 10 to be filled with a carbonated liquid, it will now be observed that the spring 32 will act on the head 33 for normally holding the valve disk 30 in engagement with 45 the seat 15' so that the liquid cannot escape from the vessel. However, by pressing on the head with the thumb, for. instance, the valve stem may be readily depressed for unseating the valve disk, when the liquid in the vessel will flow out through 50 the tube 28 to the passages 20 and 25 and issue from the discharge orifice 26 of the nozzle 23. As the liquid, under pressure, flows around and past the screw 27, the liquid will, of course, tend to rotate the screw and force it in the direction 55

1,885,465 of the orifice 26 where it will be held stationary with the result that the rotating liquid is broken into a fine spray or vapor by centrifugal force -as it escapes from the discharge orifice.

It is now to be noted that the head 33 coacts with the flange 17 of the cap 12 while the gasket 31 coacts with the valve stem 29 for centering the stem with respect to the nipple 15 and guiding the stem in its longitudinal movement so io that the stem will be slidably supported at spaced points above the bottom wall of the recess 19 for axial movement. The head 33 rigidly coacts with the flange 17 to obviate canting of the stem but should any slight undue looseness be present 15 between the head and flange, canting movement of the stem will be resisted by the gasket 31 and this resistance will be enhanced by the pressure of the spring 32 on said gasket. Consequently, the stem will, under normal conditions, be supported 20 to travel in a straight path so that the valve disk 30 will properly move into engagement with the seat 15' to rest flat against the seat throughout the periphery of the disk. Possibility of leakage will thus be avoided. Furthermore, it is to be 25 noted that as the gasket 31 is rigidly confined within the bottom of the recess 19, pressure of the spring 32 on said gasket will tend to feed the gasket to the valve stem 29 and thus at all times provide a sealed joint between said gasket and 30 the stem. Consequently, when the stem is depressed, the gasket will effectually prevent escape of liquid past the gasket around the valve stem. Thus, leakage of the liquid into the recess 19, when the valve is open, will be effectually ob3 5 viated and as the pressure of the spring 32 on the gasket will be increased when the head 33 is depressed for opening the valve, the action of the spring tending to compress the gasket against the bottom of the recess as well as feed the gasket j against the valve stem 29 will be most pronounced at such time.
