POWDER DISPENSING DEVICE Filed Feb. 21, 1950 Patented Mar. 17, 1953 UNITED STATES PATENT orricel PGWDER DISPENSING DEVICE Kenneth E. Sutton, Greenwood, R. I.

Application February 21, 1950, Serial No. 145,334

3 Claims.

This invention relates to a dispenser for powder such, for instance, as tooth powder.

Usually in the dispensing of powder such, for instance, as tooth powder, a cap is taken on of a can or container for the powder and the powder is poured upon the tooth brush with the usual result that some of the powder is spilled oii the brush and lost or wasted.

One of the objects of this invention is to provide a simple .and inexpensive cap for a container for tooth powder by which a predetermined amount of powder may be used.

Another object of this invention is to provide an arrangement so that the tooth powder may be spread upon a brush or some surface by a simple motion of the hand which is used to hold the powder container.

Another object of this invention is to provide a dispensing device which will be'about the same size and shape as the conventional tooth powder can and have a similar size outlet.

Another object of this invention is to provide a cap which may be manufactured at about the same low cost as the caps which are presently in use.

Another object of this invention is to provide a cap which in normal use will be retained in position upon the top of the tooth powder can so that it will not become lost and may also serve as a measuring device for the powder which is to be dispensed.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure l is a perspective View of a cylindrical container with my dispensing device provided at the upper end thereof;

Figure 2 is a sectional View on a somewhat larger scale of the dispensing device showing fragmentally the top portion of the outer container;

Figure 3 is a sectional View similar to Figure 2 but showing the dispensing device in open instead of closed position;

Figure 4 is a view of the powder being discharged into the cap prior to shaking the same out of the cap; I

Figure 5 is a sectional view on line 5-5 of Figure 3;

Figure 6 is a perspective view of the two parts of the dispensing or closure device shown in exploded or separated relation.

7 In proceeding with this invention I provide a dispensing and closure device for a powder container composed of two parts which are axially slidable and when moved into collapsed position'serve to close the dispensing opening but when moved to open position which is a predetermined position of the two parts, a space is provided into which a predetermined quantity of powder may be poured and thereafter discharged through an opening in the outer of the two members.

With reference to the drawings, it designates the powder container having a bottom rolled on as at H and a top wall I2. This top wall l2 may have a shallow neck 53 to which the closure and dispensing device is attached.

The closure and dispensing device is designated generally M and comprises an inner tubular member [5, the lower edge of which is secured to the collar it, while an end wall it closes off the upper end of this tubular member, except for an openin ll which is located at one side of the central axis of the tubular side Walls of this member It. The outer tubular member is designated generally 18 and comprises a tubular side wall portion ill of the same shape as the tubular walls of the member IE, but is slightly larger than the outer diameter thereof so as to telescope over this member is and slide axially thereof. An end wall it closes this outer tubular member and is enlarged or flanged as at 2i with a roughened surface so that the same may serve as a handle and be easily grasped between the fingers. The side wall on part of this flange is provided with an elongated opening 22 which is located at one side of this member l8 and preferably at the side which is diametrically opposite the axis from the opening ll.

The tubular portions of the members it and I8 are axially slidable and when the end walls 26 and it are in engagement, as shown in Figure 2, the opening ll is closed so that no powder may be passed out of this opening, and in order that these parts may be held in this closed position, I have provided axially extending ribs 25 extending outwardly from the tubular walls of the member 15 at various locations about its surface and have provided an inwardly extending circular rib 2% on the wall it so as to engage below the end 21 of the rib 25, while another circular rib 28 is provided at a point spaced therefrom to enter a break 29 in the rib to provide for doubly securing the parts in their closed telescopic position.

In order to hold, the parts in an open position, such as shown in Figure 3, the outer member [8 may be moved axially upwardly until the rib 26 engages the space 29, as shown in Figure 3, and in this position provide a predetermined volume 30 between the top walls or end walls I and 20 of the two telescoping members, and when in this position powder may be discharged into the space 30, as shown in Figure 4, and after this space is filled, then by positioning the container from an inverted position to a generally horizontal position, the powder may be dispensed through the opening 22. By rolling the can when in this generally horizontal position, the powder may be nicely discharged through this elongated opening and spread along the tooth brush or if some other powder is used for some other purpose, it may be nicely controlled in this manner.

In some cases a paper washer 33 may be inserted beneath the end wall 20 to provide a cushion-like closure or seal.

The closure member 19 may be entirely removed by exerting suflicient pull to slide it over the ribs 25.

I claim:

1. A dispensing closure device for a powder container comprising inner and outer telescoping tubular members slidably related in a direction axially of the members, both of said members having a tubular wall and end walls spanning the tubular walls in a single plane at right anglesto the axis of the members at the corresponding ends of the members, an opening in the end wall of the inner member at one side of the axial center of the members and an opening in the tubular wall of the outer member at the diametrically opposite side of the axial center of the members, stop means to prevent rotation of the members whereby when the end walls are separated a discharge passage through said openings and between said end walls is provided.

2. A dispensing closure device as in claim 1 wherein stop means carried by said members limit the movement of the end Walls from each other to predetermine a space of a certain volume for measuring the amount of powder.

3. A dispensing closure device as in claim 1 wherein interengaging means carried by said members hold the end walls of the members in engagement to close the container.
