DISPENSING CONTAINER HAVING A SPRING-BIASED CURVED SLIDING CLOSURE

Application October 8,1947, Serial No. 778,629

Claim. (Cl.

The invention relates to new and useful improvements in a dispensing container for powdered materials.

An object of the invention is to provide a dispensing container for powdered materials where- 5 in the dispensing opening or openings formed in the closure member of the container are closed by a rigid sliding unit shaped so as to make firm contact with the inner face of the closure member.

A further object of the invention is to provide 10 a dispensing container of the above type wherein the closure member is formed with a raised breast shaped to conform to a segment of a cylinder with the sides closed and wherein the control slide is curved on its outer face on the same radius as 15 the inner face of the breast.

A still further object of the invention is to provide a dispensing container of the above type wherein the breast at one side of the center is formed with a slot extending lengthwise thereof 20 and at the opposite side of the center is formed with a dispensing opening or openings and wherein an operating finger member is disposed on the outside of the breast and connected through the slot with , a rigid control slide holding it in firm ²⁵engagement with the inner face Of the breast.

A still further object of the invention is to provide a dispensing container of the above type wherein the control slide is moved to closed position by means of a bowed spring member, one 30 end of which is rigidly attached to the inner end of the finger member and the other end is detachably connected with a depending skirt on the closure member.

These and other objects will in part be ob- 35 vious and will in part be hereinafter more fully disclosed.

In the drawings, which show by way of illustration one embodiment of the invention:

Figure 1 is a vertical sectional view through a 40 container embodying the improvements with the control slide in closed position;

Figure 2 is a view similar to Figure 1, but showing the control slide moved so as to uncover the , openings for dispensing; ⁴⁵

Figure 3 is a plan view on a smaller scale of the container with parts broken away to show the manner of supporting the abutment end of the operating spring; ₅₀

Figure 4 is a view showing the control slide and spring in assembled position ready to receive the operating finger which when headed will hold the control slide in firm contact with the breast Of the container; 5S

222—517)

Figure 5 is a sectional view on the line 5—5 of Figure 1; and

Figure 6 is a view showing the breast as provided with sifting openings instead Of a pouring opening as shown in Figure 3.

The improved dispensing container comprises a body portion I, preferably made of metal. Said body portion is beaded a short distance from the upper end thereof, as indicated at 2. A closure member 3, also preferably of metal, is provided with a depending skirt 4 which makes firm frictional engagement with the outer face Of the body wall above the bead 2. The container body and closure member are preferably rectangular in cross section with rounded corners, as shown in Figure 3.

The top portion Of the closure member is shaped so as to provide a breast 5 which conforms to a segment of a cylinder. The breast is closed at the sides thereof by members 6, 6 which are formed integral with the breast and the closure top. The breast is provided with a slot extending longitudinally thereof as indicated at 7.

In one form Of the invention, the breast is provided with a rectangular pouring opening 8. The opening is disposed at one side of the transverse center line of the breast and the slot is disposed substantially at the other side of said center line. Instead of a rectangular opening for pouring, spaced openings 9, 9 for sifting, such as shown in Figure 6, may be used. The openings in the breast are controlled by a slide

10. This slide 10 includes a curved portion the outer face of which is curved on the same radius as the inner face of the breast. The slide is also provided with side members 11, II which are made integral with the control slide so as to form therewith a rigid closure unit. The side members 11, II of the slide lie close to the side member 6, 6 of the breast so that no powder is likely to pass between the side members II, II and the-side members 6, 6.

A bowed spring 12 has the inner end thereof bent at 13 so that it will contact with the inner face of the slide unit. There is an opening through the spring and an operating finger member 14 is provided with a shank 15 which extends through the slot and through the opening in the spring. The inner end of the shank is riveted or otherwise provided with a head 16 which firmly attaches the spring to the slide unit and the slide unit to the breast· so that the outer face of the slide unit will contact with the inner face of the breast. The other end Of the bowed spring is anchored on the closure mem2,575,108 ber. Said outer end is bent at an angle, as indicated at 17, and is adapted to engage between the top 3 of the closure member and the lugs 18, 18 struck inwardly from the skirt 4 of the closure member.

The upper end of the container body is bent inwardly slightly, as indicated at 19, and this gives room for the lugs 18 of the closure member. The outer end of this bowed spring is snapped between the lugs and the closure top 3 and thus the bowed spring forms a unit with the closure member. The spring normally moves the control slide so as to close the opening or openings through which the powder is to be dispensed.

It is noted that the closure unit is a rigid unit so that the curved member thereof will not spring away from the inner face of the breast. The outer face of this closure unit is die shaped so as to conform closely to the curvature of the inner face of the breast, these two surfaces being formed on the same radius. Furthermore, the slide unit is held by the operating fingerpiece in firm contact with the breast so that the end 20 of the curved portion 10 of the control slide will move in contact with the inner surface of the breast and will cut off the flow of powder through the openings when the fingerpieee is released.

When the slide unit is moved to open position, as shown in Figure 2, it will remain closely in contact with the breast at the end 20 thereof. There is no chance, therefore, for powder to work between the outer surface of the slide unit and the inner face of the breast. Therefore the cutoff is clean and leaves no powder to accumulate between the slide and the breast which can work out through the closed openings. In other words, when the slide unit moves to closed position, the shearing effect will be so effective that all of the po wder will drop back into the container body.

It is obvious that minor changes in the details of construction and the shaping of the parts may be made without departing from the spirit of the invention as set forth in the claim.
