SIFTER-TO'P RECEPTACLE AND CLOSURE THEREFOR.

Application filed December 18, .1923. Serial No. 681,407.

To all whom it may concern." 3

Be it known that I, GLEN S. HUMPHREY,

a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Heretofore sifter tops for talcum powder.

cans have been usually provided with a rotary or sliding perforated disk, or with a friction cover for closing the same, which types have been found to possess certain difficulties and disadvantages.

It is, therefore, the main object of the present invention to provide an extremely simple and inexpensive form of closure for sifter top receptacles which serves to e1fec tually close the sifter openings against the escape of the contents oft-he receptacle and to prevent the ingress of dust, foreign matter or the like to the receptacle.

As a further object the invention comprehends a closure of the character set forth which greatly facilitates the manipulation of the same to uncover the shifter openings.

With the above recited and other objects in view, the invention resides in the novel construction set forth in the following specification, particularly pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaning of the terms in which the claims are expressed.

In the drawings Figure 1 is a side view of a sifter top receptacle equipped with a closure constructed in accordance with the invention.

Fig. 2 is a fragmentary enlarged sectional View therethrough with the closure in its closed position.

Fig. 3 is a similar view with the closure in open position.

Fig. 4 is a fragmentary plan view of the receptacle.

Fig. 5 is a horizontal sectional view taken approximately on the line 55 of Fig. 2.

Referring to the drawings by characters of reference, 10 designates a receptacle provided with a covering apron 11 at its upper end which has secured thereto in the usual manner an inverted cup shaped neck 12, the top wall 13 of which 153 formed with an annular series of discharge openings 14.11

In the present instance upper wall 13 is pro-' vided with an upwardly pressed portion 15, the purpose of which will be hereafter set forth. l/Vithin thelower end of the neck 12 a disk. 16 is frictionally fitted, said. disk having, arcuate cutaway portions 17: definlng a central bearlng portion 18 having a bearing opening 19. The closure member consists, of a disk which preferably includes a metal layer 20 and a felt layer 21 which is superimposedupon the metal layer. -A stem 22 extends through an opening in the disk andan opening 23 in the upraisedportion 15 of the neck top 13.

Out-stuck ears 241 are provided on'the stem 22 above the closure member and a coiled expansion spring 25 is interposed between the under side of the disk and the central bearing portion 18 of the disk 16, wherebythe closure member is normally forced in contact with the under side of the top 13 of the neck I to close the discharge openings 14. The

upraised portion 15 provided affords a clearance space for the reception of the ears 2%.

In order to provide means to permit of the A retention of the closure member in a position to uncover the discharge openings 14, the stem 22 is provided adjacent its upperend with a lug 26. The opening 23 is elongated to allow for the passage of the lug 26 therethrough by slightly canting the stem 22 as illustrated in dotted lines in Fig. 3. At its extreme upper end the stem is preferably provided with a knob 27 to afford means for manipulating the stem to move the closure from closed to open position or vice versa.

In use and operation the spring 25 nornrally functions to hold the felt layer of the disk in close contact with the under side of the top 13 of the neck 12. When it is desired to dispense the contents of the can or receptacle, the stem is forced. downwardly together with the closure member against the action of the spring 25. After the lug 26 has been moved through the opening 23 the same engages beneaththe upraised por tion 15, as illustrated in Fig. 3, due to the inherent tendency of the spring to straighten the stem from its canted position. It

thus follows that when the can or receptacle is inverted the powder will discharge through the openings 17 in the lower disk and thence around the closure member and through the discharge openings 14. When the requisite amount has been dispensed the user again cants the stem 22 to disengage the lug 26 which is then forced upwardly through the opening to the normal position illustrated in Fig. 2, whereby the discharge openings are closed.

From the foregoing it will thus be seen that a comparatively simple and inexpensive but effectual closure for powder cans or other analogous receptacles has been provided which will function to simplify the closing and opening operation.

I claim:

1. In a sitter top receptacle, a receptacle body, a neck provided with an upper end wall having discharge openings therein, a bearing element secured in the lower end of the neck, said upper wall of the neck and said bearing element having alined central openings, a closure device within the neck including a closure disk, a stem extend ng axially through the closure disk and the aligned openings and provided with a stop engaging the upper side of the disk, an expansion spring encircling the stem and d sposed between the under side of the disk and the bearing element, for normally moving the disk into contact with the under side of the under wall of the neck to close the upper end wall, of means for controlling the closing and opening thereof comprising a closure disk mounted for movement with-- in the neck, a bearing spider secured in the lower end of the neck, aligned openingsin said spider and the upper end of the neck, a stem extending through the neck, the closure disk and the spider, said stein having ears engaging the upper side of said disk, a coiled expansion spring surrounding the stern and interposed between the under side oi" the closure disk and the spider for noriii-all e'll'ecting the seating oi. said closure (1 sk against the end wall of the neck to close the openings, and a radial lug adjacent the upper end of the stern adapted to be moved through the opening in the upper end of the neck to engage said upper end for retaining the closure disk in unseated relation.
