POWDER DISPENSING CONTAINER I Filed June 1, 1945 T51- T m awe/whom Ionia Jikrmani/ Patented Aug. 30, 1949 rowmm msrsnsmc CONTAINER Louis Hermani, Baltimore, Md., assignor to Continental Can Company, Inc., New York, N. Y., a corporation of New York Application June 1, 1945, Serial No. 597,098
1 Claim. (01. 222-560) The invention relates generally to' container structures and primarily seeks to provide a novel container of simple and attractive design which can be economically manufactured and employed in the packaging and dispensing of powdered substances.
In the manufacture of containers of the character stated problems have been presented in developing powder dispensing containers which are substantially sift proof and yet of such simple design as to permit economical manufacture. Many containers have been designed for the dispensing of powdered substance, but no such container of which I am presently aware provides the desired qualities of simplicity in design and efllciency in the way of being proof againstinadvertent sifting. The container structure of the present invention has been designed to fill these needs.
In its more detailed nature the invention has for an object to provide a container of the character stated having a convex raised portion equipped with a dispensing opening, an elongated slide held throughout its length in contact with the raised portion against resiliency inherent therein tending to straighten the same, thereby to provide tight yieldable contact between the slide and raised portion at and adjacent to the dispensing opening, and a finger piece attached to the slide by manipulation of which the slide may be moved to uncover or cover said opening.
Another object of the invention is to provide a container structure of the character stated in which the convex raised portion has parallel straight sides forming side guides for the lateral edge portions of the elongated slide.
With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claim, and the several views illustrated in the accompanying drawing.
In the drawings:
Figure 1 is a perspective view illustrating a container embodying the invention.
Figure 2 is a plan view of the dispensing top or breast of the container with the invention embodied therein.
Figure 3 is a vertical longitudinal section 2 through the breast structure illustrated in Figure 2, the slide being shown in the dispensing opening closing position.
Figure 4 is a view similar to Figure 3 with the slide moved into position'for exposing the dispensing opening.
Figure 5 is a vertical cross section taken on the line 5-5 on Figure 3.
Figure 6 is a detail vertical longitudinal section illustrating the slide and the attaching rivet or finger piece before they are assembled on the breast.
In the example of embodiment of the invention herein disclosed, the container includes a body 5 of well known form which is oval in horizontal cross section and is closedat its lower end by a suitably attached end closure 6. At its upper end the body is provided with the usual outwardly bent bead 1 which is spaced 2. distance below the open top of the container body.
To the top of the container is secured the usual breast generally designated 8. The breast preferably is drawn from a single piece of metal to include the flat top portion 9 and a depending skirt i0 adapted to frictionally embrace the top portion of the body 5 above its bead I. The breast also is formed to include a convex raised portion l l defined at the sides by upri ht straight wall portions l2 arranged in parallel spaced relat on in the manner clearly illustrated in Figures 1, 2 and 5.
The convex radial surface ll embossed on the top of the breast 8 is equipped with a longitudinal slot I3 and a transverse dispensing opening I I. A rectangular shut er or valve slide I5 preferably formed of spring brass and which normally is flat as illustrated in Figure 6 is held against the inner face of the raised portion Ii by a rivet or finger piece IS the shank of which passes through the slot l3 and through an aperture in the slide and is upset as at H beneath said slide.
It will be apparent that by forming the slide i5 of a piece of spring brass which is normally flat, and then securing the same against the curved surface of the raised portion II in the manner clearly illustrated in Figures 3, 4 and 5, the inherent tendency of the slide to straighten out to the normal position illustrated in Figure 6 will cause the same to engage in tight frictional contact against the undersurface of the raised assoyaa 3 portion ii, thereby assuring against inadvertent sifting of powdery material between the slide and the raised portion ii and out through the dispensing Opening 3.
It will be apparent by reference to Figures 2 and 5 of the drawings that the long side edges of the rectangular slide i5 are effectively guided by the parallel upright wall portions l2. rivet or finger piece It constitutes the wall means for holding the slide against the convex, outwardly projecting wall portion H, and by forming the slide of a normally flat and straight piece of spring brass as shown in Figure 6 and attaching the same to the convex portion ofthe breast in the manner stated, it is unnecessary to provide any spring means for constantly holding the slide in tight contact with the raised portion ll of the breast.
It will be apparent that by manipulating the member l6 as a finger piece, the slide may be moved back and forth within the limits of movement afforded by the slot i3 for closing the dispensing opening I in the manner illustrated in Figure 3, or for exposing said opening in the manner illustrated in Figure 4 to permit dispensing of substance from the container through said opening.
While the breast is herein shown as equipped with a dispensing opening which is rectangular and transversely disposed, it is to be understood that the opening may be shaped differently, or a plurality of small apertures may be provided if desired. It will also be readily apparent that apertures may be provided in the slide for cooperating with a large dispensing opening of any given shape formed in the convex portion ll of the breast.
While one form of the invention has been shown for purposes of illustration, it isto be clearly understood that various changes in the details of construction and arrangement of parts may be made without departing from the spirit and scope of the invention as defined in the appended claim.
A dispensing top for containers comprising, a
opening and held throughout its entire length'and breadth in full surface contact with said surface against its inherent tendency to flatten out by a single rivet attached thereto intermediately of the ends thereof and passed through said slot and engaging the exterior of said surface, side edge portions of said slide extending full length in close proximity to and being guided by said parallel side wall portions so as to be held by I said side wall portions against turning askew, the inherent tendency in said slide to flatten out being effective to cause the end Portion thereof adjacent said opening to engage in very tight contact with said surface adjacent to and over said opening.
