Application filed August '27, 1926. serial No. 151,879.

This invention relates to certain improvements in powder containers, and particularsuclrcontainers. I

It s desirablejin producing powder 0011-.

tainers that the dispensing orifice of the container be tightly closed whenlin non-use so as to prevent accidental loss or spilling of the contents of the container. It is fur ther desirable in this class of containers that.

the parts be ofsimple forinand few in numbersofthat the container may be commercially produced at low cost.

p it is the'especial object of the present inv'ention'to produce an improved closurefor the. container which shall be substantially powder tight when in non use, and inwhich the partsare' so constructedand' arranged as to be capable of large production at low cost, and easily assembled.

With this and'other objects not specifically referredto in view, the invention consists in certain novel parts, arrangements and combinations which will be described in connection with; the drawings and the novel features pointedout in theclaims hereuntoannexed. v

In these drawings,-

Figure 5 is a detail view of one of the parts ofthe closure; 7 T

Figure G is a bottom view of a modified form of closure,and

Figure 7 is a central vertical sectiontaken devices which are simultaneously operated so that a practically leak-proof top closure is provided. While the specific type of 010- sure'may be somewhat varied, in the articular form shown, there is provided as ell or cap having a flange or skirt 1,'by which it may besecured to a container, and a to 2 which may be either flat or slightly roun ed, as shown. This shellis provided with l distributing orifices 3 and a slot 4 which is, as shown, wing orbutterfiy shaped and hereinafter referred to. I p

The'distributing orifices 3' of the top are closed when in non-use by a pair of guards in the form of thin metal plates 5, 6, which 2 leakage of powder fromthe closure is al most entirely prevented. Various constructions may be employed for positioning and operating these plates; but in the best constructions means will be provided whereby the plates are held in close frictional engagement withthe top. In the particular I construction shownfeach of the plates is 'FigureB sa bottom VIEW otthe structure providedwith a slot 9. Through these'slots is passed a shanklO havingla head 11. The

slot in the plate 5 issomewhat shorter than that, in the plate. 6, and the. shank 10 iscsecurely fastened to the plate 5 b as indicated at 12, the plate 5 eing held between the burring and shoulders. 13 formed on the shank.

It will be observed that by turning the shank the plates 5, 6 are simultaneously turned and theiropenings brought into register with the openings in thetop. Various "means may be employed for rotating the shank, but. in the. particular construction burring,

shown, the top plate 5 is utilized for this purpose, being provided with an extension 14 formed with a finger-piece 15, these parts being preferably, as shown, integral with the plate. If desired, the to 2 may be formed with projections 16 which engage a hollow 17 formed on the under side of the finger-piece for stopping the rotation of the handlewhen the orifices are in registering position. For holding the plates in close frictional contact with the top, there is provided a coil spring 18 which bears against the under side of the plate 6 and against a head 19 which sets against projections 20 formed on the end of the shank. For convenience in assembling, this head 19 is, as shown in Fig. 5, provided with a slot 21 and with recesses 22 extending at right angles to the slot. In assembling, the spring is put in position and the head 19 is slipped over the shank and given a quarter turn, so that the recesses or grooves 22 will engage the shoulders 20 on the shank and securely hold the parts in position.

Instead of the coil spring shown in Fig. 2, a spring plate such as shown in Fig. 7 may be employed. In this construction there is provided a plate 23 having a lurality of spring. legs 24 arranged to ear against the under side of the plate 6 at points between the perforations 8. This spring plate, as shown, is provided with a slot 25 and grooves or recesses 26, and is assembled in the same way as the head 19, before referred to. It will be noted that, by reason of the shape of slot 4, the shank may have a limited rotary movement sufiicient to effect the registration of the openings in the plates and in the top, itwill also-be.

observed that the spring 18 orthe spring plate 23 has a rotary movement with the shank, so that the distributing orifices are not interfered with.

7 While the invention has been shown and described in its preferred forms, it will be understood that various changes may be made in the particular shape and arrangement of the parts without departing from the invention as defined in the appended claim, and that the closure may be used with any desired form of container.

VVha-t I claim is:

1. A sifter closure for containers, comprising a shell having a skirt by which it may be secured to the container and provided with distributing openings in itstop, a pair of plates, one arranged above and one below the top of the container and provided with distributing orifices, a rotary member common to the plates, means for rotating the member for simultaneously rotatin these plates to effect the registration o? their orifices with the orifices in the shell, and a spring associated with the member and turning therewith for effecting a close frictional contact of the plates and the shell.

2. A sift-er closure for containers, comprising a shell having askirt by which it may be secured to the container and provided with distributing openings and a central slot in its top, a plate having distributing openings arranged above the casing and p in close frictional contact therewith and provided with a slot, a second plate having distributing openings arranged below the top of the container and provided with a slot, a rotary shank passing through the slots in the top and in the plates and secured to one of the plates, a spring associated with the shank and turning therewith for pressing the plates into close frictional contact with the top of the shell, and a handle formed from an extension of the top plate for rotating the shank and simultaneously rotating the plates. i i i 3. A sifter closure for containers, comprising a shell having a skirt by which it may be secured to the container and provided with distributing openings in its top, a pair of plates, onearranged above and one below the top of the containerand provided with distributing orifices, a handle for simultaneously rotating the lates to effect the registration of their ori ces with the orifices in the shell, a shank passing through the to and the plates and secured to one of the p ates, a recess in the shank, a head secured in the recess, and a spring surrounding the shank and interposed between the head and the bottom platefor holding the plates in close frictional engagement with the top of the shell.

4. A sifter closure for containers, comprising a shell having a skirt by which it may be secured to a container and provided with distributing openin s in its top, a pair of plates, one arranged above and one below the top of the container and provided with distributing orifices, a handle secured to one of the plates for simultaneously rotating the lates to effect the registration of their ori ces with the orifices in the shell, a rotary shankpassing through thetop and the plates and secured to one of the plates, a recess in the shank, a head, having a slot by which it may be passed over the end of the shank and recesses at right angles to the slot in which the shank may seat after the head has been given a quarter turn, and a spring turning with the shank and interposed between the head and the bottom late for holding the plates in close frictiona engagement with the top of the shell. 7 V

In testimony whereof, I have hereunto set my hand. 7

PHILIP REUTTER.
