Specification of Letters lPatent. Patentes@ A111111. 29, 1919.

Application led January 31, 1916. Serial No. 75,216.

To all whom t may concern:

Be it known that I, EnMUNn HOFFMAN, a citizen of the United Brooklyn, in the county of Kings and State of New York, have invented a new and useful Tmprovement in Sifter-Tops for Talcum- Powder Cans and the like, of which the following is la specification.

vThis invention relates in general to sifter tops for powder .dispensing packages and the like and has more particular reference to sifter top boxes provided for the packaging of talcum and face powder, although it will be manifest that the inventionhas other and wider application;

A principal obJectof the invention is the structed and arranged that no powder may leak out when the box is closed, and this without regard to the amount of handling and jostling in shipping that the-package may receive. v

Talcum powder boxes arefrequently packed with many other articles in grips and traveling bags where they maylrub against certain surrounding objects and the` sifter top moved angularly so that the perforations come in registration and der leaks out into the bag.

Allt is'an object of this inventionto pro' vide a construction where this will not occur. Furthermore, indenting of the tops of powder boxes constructed prior to my invention has frequently permitted the powder to leak out, whether the perforations of the parts were in registration or not. This also my present invention aims to overcome.

A still further object of the invention is the provision of such a powder box which will be readily operable, which will not diEer in appearance materially from those already in use and which may be economically constructed. y

Other objects and advantages ofthe invention will'be apparentfas it is better understood from the following description when considered in connection with the aceompanying drawing illustrating a preferred embodiment thereof. c

Referring to the drawing?? l.

Figure 1 is a partial side view of a tal-cum powder box equipped with acover embodying my invention;

States, resi ding in fastening 14 in the top of the cover.

the pow- Forv the purpose of illustrating my invention I have shown on the drawing a talcum l powder box comprised of a body l0 having a cover 11 on the top of which is secured a neck 12 by seaming or otherwise suitably its lower edge 13 in an opening The neck 12 is closed at its top 15 to provide a stationary top, this top being perforated as is usual with apertures 16 arranged at intervals on a circumference about the center of the neck.

Upon the outer face of the stationary cover or top 15 is/placed a disk 17 which may be termed an intermediate closure, this disk be.

ing alsor provided with apertures 18 extend,`

lng through it, said apertures 18 being adapted to aline with the apertures 16 under certain predetermined conditions, as will be later described. This disk is held in place, in the embodimentoi the invention shown on the drawing, by -a rivet 19 extending through it and through the stationary closure.

An outer rotatable sitter closure 20, much like that .ordinarily employed except 1n certain particulars, which will be described,

embraces the neck. The bottom edge 22 of this closure is bent in to engage the outer surface of the cylindrical part of the neck 12 beneath a number of projections 23 which hold the outer lclosure 2O in place. This closure is also provided -with perforations 24 adapted to aline with the perforations 16r and 18.

vThe stationary top 15 1s depressed at 25 arcuately about the center of movement of the disk and outer closure 20, and in the depression 25 a depressed part26 of the disk 17' is disposed, these depressions providing coperating stops which limlt the movement of ,the disk with respect to the statlonary closure. Similar coperating stops between the disk andthe outer closure are' provided by cutting awayvthe outer closure to.. provide an arcuate slot 27 and pressing thedisk .up `to provide a projection28 extendlng lnto the slot. `Fig. 4t shows the arrangement of the all@ parts when the container` is closed, and it will be noted that in this event the stop 26 is in the forward end of the depression or stop 25 in the .direction of movement of the disk to closed position, this movementin the iigrespectively in the stationary top, the disk and in the outer rotatable closure are out of registration. When it is desired to open the disk, the outer rotatable member or closure is grasped by the hand and turned in a counter-clockwise direction. The early part of this motion is unaccompanied by a motion of the disk, this motion bringing the stop 28 to the rear end of the slot`27, considered in connection with the direction of movement. When the stop 28 contacts with the rear end of the slot 27 the apertures in the disk and in the outer rotatable closure are in registration, but they are both out of registration with the apertures in the stationary top, as

-is seen in Fig. 5. Further movement of the outer rotatable closure is accompanied by movement of the disk imparted to it by the movement of the outer closure. The two movable parts thus move together over the stationary part until the stop 28 engages the forward end of the depression or sto 25 of the stationary cover, in which posit1on the apertures in the stationary cover come into registration with the already alined apertures in the disk and in the movable cover. This arrangement is seen in Fig. 6. 1n closing the container the operation is reversed,

and this by turning the outer rotatable cover or closure in a clockwise direction. First the apertures of the disk and outer closure move out of registration and later the apertures in the disk and stationary closure are moved from alinement, bringing the parts back to the position shown in Fig. 4. On the drawing the apertures in each part are spaced a distance equal to twice the operative length of the slot 27 or depression 25 and when thus arranged the apertures 24 are over the apertures 16 when the parts are arranged in closed position, at which time the apertures 18 are located halfway circumferentially between successive apertures 24 and 16.

lt will be manifest that in thus providing a sealor disk member between the cover and closure'the friction between. the parts is. increased by reason of the fact that two sets of friction surfaces must move over each other to permit opening of the container, thereby reducing and almost entirely obviating the chance of inadvertent opening of a talcum powder box while in a hand-bag or grip. Should one of the parts become loose and easily movable with respect to the others, the box ,will still be closed by reason of the fact morsa? that such movement cannot bring the .three sets of apertures into the necessary registration. Also if a container is dented in such number of operations necessary .in the construction of the package.

1t is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts. without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
