A. L. DAVIS POWDER CAN TOP Dec. 19, 1933.

Filed Nov. 3, 1932 Patented Dec. 19, 1933 j {UNITED STVIA 1,940,679 POWDER CAN Tor Albert L. Davis, Watertown, Conn., assignor to The Waterbury Brass Goods Corporation,

Waterbury, Conn., a corporation of Connecticut Application November 3 7 Claims.

This invention relates to new and useful improvements in powdercan tops, and has for an' object to provide a powder can top of simple construction and including a cover or closure for thedischarge opening or openings of the top, which cover or closure may be operated between open and closed positions by the thumb or a finger of the hand in which the powder can equipped with the top is held.

Other objects and advantages will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein satisfactory embodiments of the invention are shown. However, it will be understood that the inventionis not limited to the details disclosed but includes all such Variations and modifications as fall within the spirit of the invention and the scope of the appended claims.

In the drawing: 1

Fig. 1 is a front elevational view showing a powder can including a top constructed according to the present invention, the closure or cover of the top being in open position; i

Fig. 2 is a view of the top and the upper portionof the can, the top cover or'closure being shown in closed position; 7

Fig. 3 is a plan view of the top as shown in Fig. 2;

Fig. 4 is an enlarged central sectional view through the top; 1 Fig. 5 is a'view similar to Fig. 1 but showing a slight modificatiom' Fig. 6 is a further view of the top of Fig. 5, its cover or closure being shown in'closed position; and V Fig. 7 is a side elevational view of .the forward portion of the top.

Referring in detail to the drawing and particularly to Figs. 1 through 4, at '10 is shown the body of a can of any desiredconstruction and configuration and which is adapted to receive powder as for example tooth powder. Telescopically receiving the upper end portion of the can body 10 is my improved powder can top generally designated 11, and as the descriptionproceeds it will become evident that the top 11 may be applied to thecan .body in a manner other than by telescopically receiving the upper end portion of the can body.

Top 11 includes an upper wall '12" from which depends an annular flange or skirt-like portion 13 which receives the upper end portion of the can body. Projecting upwardly or outwardly from theupperor vtop wall12 is an extension 14 1932. Serial No. 640,948

open at its inner side whereby it is in communication with the interior of the can body and ineluding an upwardly inclined forward wall 15 and a downwardly inclined transversely curved upper wall 16 and substantially straight side walls 17. The forward wall 15 has its central portion inwardly offset as at 18,-and is preferably adjacent its upper edge provided with a discharge opening 19. v A cover or closure 20 is disposed against the inwardlyoifset portion or wall15 and lies substantially flush with the outer face of said wall, and is substantially in the form of a disc centrally pivoted to the wall as by a rivet or the like 21. This cover or closure 20 is provided with a discharge opening 22 adapted to be brought into registry with the opening 1 9 where- .by the contents of the can may be dispensed. A lug or finger piece 23 is formed with Orsecured to-the cover or closure 20 and includes a portion extending over the curved wall 16 of the extension 14 to ride thereon as clearly shown in Figs. 3 and 4. j i I The pivot. 21 for the closure or cover is concentric with respect to the wall 16 of the extension and theoperating lug or finger piece 23 lies against this wall and may beengaged by ,a finger or thumbv and shifted to shift the closure between closed and open positions. That is, the .lug 23 may be operated to shift the closure to take the. opening 22 out of registry with the opening 19 or into registry with it. The parts are preferably so arranged that when .the lug .is shifted to move the closure and, bring; its opening22 into registry with the opening .19 of the forward wall of the extension the said lug engages the straight side wall 17 .of .said extension when said openings .come into registry. Therefore, this side wall :forms astop and limits movement of the closure in one direction about its pivot; and when it is desired to use some of the contents of the can the operator simply shifts the lug 23 downwardly from the position in which it is shown'in Figs. 2 ,and 3 .intO the position in which it is shown in Fig. 1, and when further movement 'of the closure is prevented by engagement of the .lug with one of the walls 17, the operator isadvised that opening 22 is in registry with openingll). Ifhere 105 is no need or occasion for careful manipulation of the cover 20, when returning it to closed ,position-. since it cannot be given an ,excessive movement as the lug 23 would engage the opposite straight wall 17 of the extension. From '1-10 this it will be apparent that movement of the cover in either direction is limited.

From the foregoing description it will be apparent that the can 10 equipped with my improved top maybe grasped in one hand as shown in Fig. l and that the cover or closure 20 may be operated by the thumb or a finger of the hand supporting the can. When the cover has been shifted to open position the can may be inverted or otherwise manipulated to place powder on atoothbrush grasped in the other hand of the operator. When sufiicient powder has been dispensed it is apparent that the closure may be easily returned to closed position and,

the can replaced in a cabinet or the like.. The extension 14 acts as a guide or funnel to direct the powder to the discharge opening 19, and while reference has been made to the can as .used for dispensing toothpowder,-it will be obvious that it may be used as a dispensing container for other kinds of powder.

Referring now to Figs; 5, 6 and 7, the top 11 is of substantially the construction above described, and includes the extension 14 above described. However, in these figures the forward wall 15 of the extension is provided with a plurality of relatively small openings 24, and the cover member designated 25 is pivoted against this wall as by the rivet 21 and is provided with a plurality of perforations 26 adapted to be brought into and out of registery'with the perforations 24 as the cover is moved to opened and closed positions. This cover'25 is provided with a lug 27 of the same construction and having the same'functions as the lug 23 of Figs. 1, 2 and 4.

Since in Figs. 5, 6 and '7 a plurality of perforations are involved forming a sifter top, the movement of the cover should be limited in both directions about its pivot, so that at the limit of its movement in one direction it is in open position with its perforations registering with those of the forward wall of the extension and at the limit of its movement in the opposite direction it is in closed position with its openings or perforations out of registry with those in the forward wall of the extension. As will be understood, the lug 27 will engage a side wall 17 of the extension to limit movement of the cover in one direction or to open position.

The cover or closure is provided with a second radially extending lug 28 and'when the cover is shifted to closed position this lug engages the upper or top wall 12 of the improved. top and prevents further movement of the closure in one direction. Therefore, it will be understood that movement: of thenclosure in either direction is limited so that the operator need not look to see if the device is open or closed but will know that it is open when lug 27 has been moved down as faras possible and that it is closed when said lug has been moved up as far as possible, since in this latter position lug 28 will have engaged the upper wall 12 of the top. Attention is particularly directed to the fact that stops or limiting means are provided without the additionof unsightly protuberances. Further, as the lugs 23 and 2'7 ofthe respective forms ride on the curved wall lfi asmoothmovement of the cover is ob- 'tained' and there is such friction present that the including a forward wall arranged at an angle to the upper surface of the body and said extension inclining from said wall and forming a funnel like portion leading to said wall, said wall having a discharge opening therein, a closure pivotally mounted against said wall and having an opening therein, and said closure turnable between an open position with its opening registering with the opening in the wall and a closed 'position with its opening out of registry with the opening in the wall, and a stop lug on said closure in position to engage a wall on the top to limit turning movement of the closure.
