invention relates generally; tcncnnta ners for powder... More... particularly my: invention. is I concerned with an. improvedg construction. vfor sifter powder boxes; n l 1 One of the objects oi I ma invention is, to nm- .vidca highly improved and noyel. Sifter PQWder. box of the class describectwhich shall be so -constructed and arranged that it. may be opened for; effective use and subsequently :closedwhile the said :box. is: held in one hand, leaving, the other hand I of the user free at'al l times tohold an i fantor for anyother desireduse.

Another .obiectot invention to provide a highly improvedand. novel sitter: powder box of the class described: which shall; be readily:

adapted for the. manufacture thereof out of nonmetallic materials, such as paper, cardboard and the like and which at the same time shall-possess I a high degree of efficiency and practicability in use. I

A further object of my invention is to -provide a highly improved and novel sifter powder box of the classdescribed which shall comprise relatively -few and simple parts which shall be easy to assemble and which shall be characterized by the simplicity of its operation.

Other objects of my invention will become apparent in the. following detailed description thereof. i

In the accompanying drawing,

Fig. 1 is a vertical sectional View of a sifter powder box constructed and arranged in accordance with my invention;

Fig. 2 is a disassociated elevational view of the parts that go to make up the completely assembled box illustrated in Fig. 1, but of smaller size and with certain portions broken away to disclose the construction thereof; and

Fig. 3 is an elevational view, of reduced size, of the Fig. 1 form of box and demonstrating a manner of its use. 3 w V Referring now in detail to the drawing Ihave shown a powder box ID of the sifter type, constructed and arranged in accordance with my invention and comprising an outer tubular member llof any desired diameter and having the material'of the lower edge I la rolled inwardly to provide an annular abutment shoulder l2, the purpose of which will soon become apparent. Slidab-ly, nestably received within the tubular member I l is a cylindrical box unit l5 comprising an inner cylindrical side wall I6, an outer cylindrical side wall II, a bottom wall member [8 and a removable closure member 20.

The outer side wall n of the unit 1-5 fit snugly around the. inner wall 6 and is attached theretow against. axial displacement by; any suitable: means;

known to. the art, such as..foriexample, adhesivei or by friction. It is. noted that. the outer wallexeo I tends: slightly below the loweredgs of: the

Wall and terminates a relativelydalger distance; below the top. rim of the: said innerwall lfitpro-f viding an abutting annularshoulder. tactile space between the lower edges ofthe; Wall tt and H I place my bottom wallmember lflwhichcome prises a horizontal wall part lad ahdan. annular welt liibdepen'ding therefrom. Theannularwall 1. lab is designed to contactively oyerlielthe inner surfaceof the wall H .andmay be permanently attached thereto by adhesive. I The closure uni-t;

comprises a cylindricalside wall 22 of a diameeter substantially equal to that of the wall I! and box unit IE to the dotted line position 25' of Fig. .1, r .so that the apertures 30 will project above the which is adapted to be slidably received on that portion of the wall it which projects upwardly above thewall II. The downward sliding movement of the closure unit I 8 is limited by the shoulder l9 The closure unit I8 is also provided with a top wall 25, which for decorative purposes and also for distinguishing the top from the bottom, is slightly arched. The said wall 25 may be permanently held in position and sealed against leakage by providing a recessed portion 26, adjacent the top of the wall 22, into which the said wall 25 is frictionally received. It is thus seen that the box unit I5 is a complete box adapted-to hold a supply of powder P. It is also noted .from the above described construction that when the box unit I5 is slidably, nestably received within the tubular member I I it willmove downwardlyuntil the bottom edge thereof strikes the abutment portion I 2. The box ID, in this latter described position is in the closed position.

In the side Wall 22 of the closure unit [8 I provide one or more apertures 30.

In accordance with my invention as above described, and as illustrated in Fig. 3 of the drawing, a user may grasp the box In between the thumb and fingers and with one free finger exert a pushing force against the bottom wall 180,. Ifhis will cause outward sliding movement of the outer wall II and permit the powder from the box unit l5 to be sifted therethrough.

If desired, to safeguard. against leakage of the powder during shipment, a strip oftape or paper may be place over the apertures 30 to temporarily seal the same. The consumer need merely puncture one or more holes through this tape in alignment with the apertures 30 and the powder box is ready for use.

To close the box after use, and while still holding it in the one hand, it is merely necessary to exert a pushing force with one finger on thetop of the boxagainst the wall 25.

It is noted that the above described construction lends itself to the use of cardboard construction or any other suitable non-metallic material] and will be sufiiciently rigid and sturdy in view said inner side wall and attached thereto for movement therewith, said inner side wall projecting a substantial distance above the top edge of said outer side wall, said closure comprising a top wall and a depending side wall, said last named depending side wall being adapted to nestably slidably receive therein the portion of said inner. side ,wall, projecting above the top edge of the Saidouter side wall,- said outer side wall of the triple wall construction as clearly shown in Fig. 1 of the drawing.

In accordance with the provisions of the pat n em; statutes, I have herein described the principle and operation of my invention, together with construction which I nowconsider to represent the best embodiments thereof, but, I desire to have it understood that the construetion shown is only illustrative and that the invention can be carried out by other means. Also; while? it is designed to use the various features and elements in the combination andrelations described, some of these maybe altered and othersomitted without interfering with the more general'results outlined, and the invention extends to such "use.

' Having described my invention, what I claim and desire to secure by Letters Patent is:

1Q*I n a sitter powder box of the class described, in combination, an outer tubular member having an abutment portion adjacent the bottom edge ofthe inner surface of the wall thereof, a box unit adapted to hold powder therein and comprising an inner side Wall, an outer sidewall, 21 bottom wall and a completely removable closure, the'said outer side wall closely surrounding the and said depending side wall being in alignment and both being adapted to be nestably slidably received within said outer tubular member, to provide a three wall thickness of materiaLfor the major portion of said sitter powder/box, the said- 1 51;.
