COMBINED CLOSURE AND POWDER EJECTOR Filel Feb. 4, 1957 Patented Dec. 14, 19.37

` UNITED STATES PATENTl ori-'ICE coMlNEn cLosUnE AND POWDER d nJEc'ron This invention relates to an improved closure and powder ejecting device constituting an attachment for a container in which tooth powder and the like 'are sold, and oneobject o f the in- 6 vention is to provide a device of this character including a closure'plate slidably mounted inL order that an opening formed in the plate may be shifted into and out of registry-with a discharge opening in the top ofthe container, a tongue being provided along one edge of the opening in the plate so that, as the plate is shifted into position to move its opening into registry vwith the' discharge opening of the container, powder will be moved towards the discharge opening of the container for passage through the same. It will thus be seen that a supply of powder may be deposited 'directly upon la tooth brush instead of shaking the can to eject powder therefrom ontothe palm of a persons hand and then removing the powder 20' by applying a damp tooth brush to itV whichis a very unsanitary manner of applying tooth powder to the brush.

Another object of the invention is to provide improved spring meansfor yieldably holding the closure plate in closing relation to the discharge opening of the container top or head and in addition to so form the 'spring that it serves not only as a spring for yieldably holding the plate in a normal position but as a barrier which will extend along the discharge opening of the contain'er at the opposite side thereof from the tongue carried by the plate and thus prevent the powder from being moved across the discharge opening.l

Y instead of passing through the discharge opening when the plate is moved in a direction to dispose its opening in registry with the discharge opening. Another object of the invention is to so form the spring that it will be iirmly'held in operative engagement with a tongue of the closure plate and to so mount the spring in the container that. while the closure plate can be very easily moved into or out of an opened position, the spring will be lprevented from slipping out of its proper position in the container.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a perspective view of the powder container provided with the improved closure and Y powder discharge device,

Figure 2 is a sectional view upon an enlarged scale taken along the line 2--2 of Figure 1, and

Figure 3is a. sectional view taken along the line 3-3 of Figure 2.

d The container I has been shown of cylindrical 55' formation but it may be of any cross 'sectional' outline desired and may also beoi any desired dimensions. The upper portion 2 of the container is tapered towards its upper end and joined to a cap or head 3 having its upper wall 4 iiat and formed with a discharge opening 5 through which 5 powder in the container is to passwhen-the container is disposed in an inverted position. A closure plate 6 formed of sti metal or any other desired material ts against the inner- Iace of the wall 4 and is provided at one side with an i0 actuating arm slidably engaged through an opening 8 formed in the peripheral wall of the cap, as clearly shown inv Figures 1 and 3. The outer end of this actuating arm is bent to provide an abutment head or ange 9 serving to limit inward 15 movement of the closure plate by engagement with the outer face of the annular wall of the`cap and also providing a at-nger-engaging portion against which pressure may be applied to force the place inwardly without bruising the thumb or 20' finger applied to the outer end of the actuating arm. Referring to Figures 2 and 3, it will b e seen that a tongue I0 has been stamped from the plate 8 and bent inwardly to provide a powder ejecting member extending diagonally from the plate 25 along the marginal side edge oi. an opening Il formed when the tongue is bent to the depending position. This opening Il is out of registry with the opening 5 when the plate is in the position shown in Figures 2 and -3 but when pressure is 30 applied to the outer end of the arm I to force i the arm inwardly until the abutment tongue VEl makes contact with the peripheral wall of the cap, the opening II will be moved into registry with the opening 5 and the tongue Ill will serve to 35 carry powder in front of it towards the opening 5 and thus feed a quantity of powder through the discharge opening of the cap.

The closure plate is to be normally held in the closing position shown in Figures 2 and 3, and in 40 order to yieldably hold ,the plate in this closing position, there has been provided a spring l2 formed from 'a strip of resilient metal. This strip of resilient metal is bent in spaced relation to one end to provide a bridging bar I3 having an arm 45 III extending therefrom and is then bent to provide a second bar l5 disposed in opposed and spaced relation to the bar I3 and having bowed portions I6, the adjoining or adjacent ends oi' which are connected by a bridge I1. Atthe op- 50 positeend of the spring from the arm I4, the resilient strip is bent to form an arm I8 corresponding to the arm I4 and terminating in an inwardly extending tongue I 9 which is overlapped by the bridging bar I3. It will thus be seen that 55 and provided with arms Il and I8 at its ends which are seated in sockets 2n stamped outwardly from the annular wall of the cap at opposite sides thereof. A billor tongue ZI extends from the plate 8 at the opposite side thereof from the actuating arm or strip 1 and this tongue 2| fits between the inner ends of the bowed portions I6 of the springs against the bridging portion I1 and terminates in a lip 22 which overlaps the bridge I1. Therefore, tension of the bowed portions I 6 will yieldably hold the closure plate in the closing position shown in Figures 2 and 3 and return it to this position after the plate has been moved to dispose its opening II in registry with the opening i and a finger or thumb removed `from the outer end of the actuating arm 1. The lip 22 maintains the tongue 2| and the bridge I1 in proper engagement with each other and since the arm Il is formed integral with one end of the bar I3 and the tongue Il is overlapped by the other end of the bridging bar I3, the arms Il and Il will be firmly seated in the sockets 20 and prevented from slipping out of the sockets when pressureis applied to the outer end of the arm 1 to shift the plate l inwardly and dispose its opening in registrywith the discharge opening of the cap. It should also be noted that the bridging bar I3 extends along a side edge of the opening 5 at the opposite side thereof from the tongue I0 and that, when the plate G is shifted inwardly, the tongue I0 moves towards the bridging bar. Therefore, this bridging bar constitutes a barrier extending along the discharge opening 5 at the opposite side thereof from the tongue III and any powder between the tongue I l and the opposed portion of the bridging bar will be forced through the opening 5 as the opening II moves into registry with it. The fact that the tongue I0 extends diagonally, as shown clearly in Figure 3, will also aid in directing the powder through the registering openings. Upon release of the actuating arm the bowed portions of the spring will return `the plate to the closing position and air and moisture will be excluded from the container.
