Between thev valve I `and thershcrt-'centralopen- 'ing I-3 thestem I4 isjprovidedwith a ser-iesof A- Yannular serrations -'I 6 "and a spring1 I1. The-iserrations I6 are preferably saw-toothed in proiile and *point in theV direction of the vibration ring 'II. `fI`he-serrations16 areiformed by a series'of adjacent converging "surfaces I8 and AI9 which taper toward 4thelongitudinal 'axis 'of i the stem L f4.

'A' spring I'I -is interposed betweenithe A4o vibrationring II andand'thevalve I 5.
.Operation ofthe dispenser'is as follows: The containeriisheldbyihe fingers .and palm of the 'hand in na downwardly inclined positionjso .f that Ithe `discharge slot IIl islowermost "The "fore- 'are slioietly 'flexible'to yield as thebody is #45Tlngerispressed'against'the'prtrudingextremity forced into position, and form a groove or chan nel 5 accommodating the extremity of the inturned end 2 forming therewith a fluid-tight interlocking joint. The outer end of the conical of the stem I4, moving the valve to its dotted line position shown in Fig. 2. This movement is accompanied by vibration ring I I and the stem le as the serrations I6 catch on the margins of sealing walls 4 is provided with a reinforcing rim 50 the central opening I3. Such vibration loosens 6 and a depending skirt 'I which, when the closure body is in position, may bear against the inturned end 2.
A dispensing spout 8 of frusto-conical form extends axially outwardly from the inner or 55 and that proper engagement between the serra.- Y
facilitates its flow from the slot I0.
It should be noted that the stem I d may have a fairly loose fit within the central opening I3,
asoaese if desired, be formed of plastic. In such case it is possible to make the entire dispenser out ofv plastic material if the nature of the powdered material is such that it might attack metals.
It will be noted that the serrations define sawtooth-like annular projections or rib members having converging tapered surfaces. The arinular surfaces which form the rib-like members taper inwardly relative to the longitudinal axis of the stem, and the surface i8 which faces outwardly towards the discharge end of the spout 8 is provided with a substantially greater taper than the inwardly facing surface I9. The underside of the plate or ring Il is beveled or cut away around the opening i3. This arrangement enables the stem to return readily by spring action to its outer position wherein the valve closes the port lil. Thus, normally the lateral discharge port or opening il! remains closed and is automatically closed as soon as ones nger is removed.
The valve I is preferably a cup-shaped piston with cylindrical walls and its open end directed axially outwardly so that any powder which does not fall out and lies above the valve, is entrapped therein for later discharge rather than compacted between the valve and end of the spout.
Many other embodiments of the invention may be resorted to without departing from the spirit of the invention.
I claim:
1. A dispenser for powdered materials, comprising: a discharge spout having a laterally directed discharge opening at its extended portion; a slide valve within said spout for controlling said opening; a stem connected with said slide valve and protruding from said spout for moving said valve to an open position; a perforated partition within said spout, the inner portion of said stem extending through said partition; and a plurality of closely spaced annular vrib formations on the inner portion of said stem engageable with said partition to vibrate said stem and partition during movement of said stem thereby to agitate the contents of said spout.
stem, said partition provided with an opening accommodating said stem, the projections on said stem engageable with the edges of the partition forming said opening as said stem is reciprooated to vibrate said stem and partition thereby to agitate powdered material contained in said discharge spout.
3. A dispenser for powdered materials, com# prising: a discharge spout having a discharge opening at its extended portion; a slide valve within said spoutv for controlling said opening; a stem connected with said slide valve and protruding from said opening for moving said valve to an open position; a perforate partition within said spout, the inner portion of said stem extending through said partition; a plurality of axially spaced annular members on the inner portion of said stem engageable with said partition to vibrate said stem and partition during inward movement of said stem thereby to agitate the contents of said spout; and resilient means between said valve and partition for urging said valve to its closed position.
4. A dispenser for powdered materials comprising a discharge spout having a laterally directed discharge opening at the outer end thereof, a slide valve within said spout for controlling said opening, a stem connected with said slide valve and protruding from the outer end of said spout for moving said valve to an open position, yieldable means tending to move said valve to closed position, said stem being provided with a plurality of adjacent annular serrations, and vibrateable apertured means in the other end oi said spout. said stem extending through an aperture in said vibrateable means and the serrations on said stern engaging said means during movement of said valve to open position to vibrate the contents of said spout.
5. A dispenser as recited in claim 2 wherein the axially spaced annular projections on said stem define outwardly projecting rib-like members having converging surfaces tapering toward the longitudinal axis of said stem, the taper on the surface facing inwardly from the outer end oi the stem being substantially greater than the taper on the surface facing outwardly thereof.
