POWDER CAN Filed June 11 1940 hw=rmm Patented Aug. 24, 1943 POWDER- CAN Edward E. Baker, Larchmont, N. Y., assignor to Continental Can Company, Inc., New York, N. Y., a corporation of New York Application June 11, 1940, Serial No. 339,966
1 Claim. 7 (Cl. 221-64) The invention relates to new and useful improvements in a sheet metal can for powdered materials, and more particularly to a can have ing a perforated neck portion controlled by a rotatable perforated closure cap which may be used for sifting the contents'of the can.
An object of the invention:is to provide a can of the above type wherein the neck of the can and the closure member thereforhave a flat seating contact extending substantially from one side of the neck to the other, and wherein the sifting perforations and the stop lugs for insuring registration or non-registrations of the perforations are all disposed within'said surfaces having flat seating contact.
In the drawingg V Figure l is a view partly in vertical section and partly in side elevation through the upper portion of a can embodying the improvements;
Fig. 2 is a plan view of the can with the closure cap removed, showing the perforations and the recesses in the end of the neck;
Fig. 3 is a plan view of the closure cap for the can, and
Fig. 4 is a sectional view on the line l4 of Fig. 1, said section being taken on the arc of a circle as indicated in Figure 3.
The improved powder can includes a body portion i which may be of any desired construction and shaping, but preferably it is rectangular in cross section and rounded corners. Secured to the upper end of the body portion I is a breast portion 2. Said breast portion 2 has a depending skirt 3 making frictional engagement with the body wall above the bead ii. A sealing gasket 5 is contacted with by the edge of the body wall to prevent powder escaping. Said breast portion 2 has an opening centrally therein, and secured to said breastportion is a neck Q. Said neck is cylindrical in shape and is secured to the breast 2 by the interfolding of the lower edge portion of the neck with the metal surrounding the opening in the breast, thus forming a very tight seam indicated at l in the drawing.
Said neck portion is closed at the outer end and the closed outer end is shaped so as to provide a flat seating portion which extends substantially from one side of the neck to the other. Said flat seating portion terminates at 9 as illustrated in the drawing, and the portion of the neck between the fiat portion and the cylindrical wall of the neck is tapered upwardly and inwardly from the neck proper to the fiat seating portion 8.
The flat seating portion of the neck is provided with a series of perforations it), It. These perforations are disposed inside of and adjacent the outeredge of the fiat seating portion. The. openings are spaced from each other the same distance and are located the same radial distance from the center of the neck portion.
, Between the perforations and the center of the neck portion is a series of recesses H, M, and
. these recesses are spaced from each other. They are similarly shaped and are, spaced the same distance from the center of thejneck portion. Each recess terminates in radial end walls l2 and iii. The end portion of the neckcentrally i' thereof and inside of these recesses lies in the same plane as the portion of the closure, end containing the perforations it. A closure cap it isapplied to the neck portion. Said cap has a depending skirt l5. Said cap has a flat seating portion extending substantially from one side thereof to the other and conforming to the flat seating portion H] of the neck. This flat seating portion of the cap makes contact with the flat seating portion of the neck and is the main contact between the cap and the neck. Between the fiat seating portion of the cap and the skirt of the cap is an inclined annular portion i6 which conforms'to the tapered portion between the cylindrical wall of the neck the flat seating portion of the neck. However, this annularportion It of the cap is preferably disposed so that it does not contact with the tapered portion of the neck, and this will per iit the seating surface to be placed in engagement with each other. The flat seating portion of the cap is provided with a plurality of perforations H, which perforations are spaced from each other the same as the perforations it, iii in the neck. They are likewise spaced the same distance from the center of the cap as the perforations id, so that these perforations may be brought into register for the purpose of sifting the contents of the can. The closure cap is rotatively attached to the neck portion, and this enables the cap to be turned so as to bring the perforations therein into alignment with the perforations in the neck, or to place the can so that the perforations will be out of register and thus tightly closed.
As a means for rotatively connecting the cap to the neck portion, a rib it is provided in the neck portion, and the lower edge portion of the skirt is headed as indicated at 8 so that an annular recess is formed on the inside of the skirt which receives this rib i8. closure cap is dimensioned so that it is substan- The skirt id of the a The flat seating portion of the closure cap is provided with a plurality of spaced lugs 26. These spaced lugs 26 are so disposed relative'to the recesses H in the neck portion that there is a lug extending into each recess When the closure cap is rotated so that the lug 28 contacts With the radial wall I2, then the perforations are in alignment, and when this lug 26 contacts with the radial wall i3, then the perforations are out'of register, and in fact, the perforations in the closure can will then be disposed midway between the perforations in the neck portion. These perforations are quite widely spaced, and there fore, when the rotary closure cap is positioned that the stop lug contacts with the radial end wall is, the can is tightly sealed and there is no chance for any leakage of powder. By'tiie pram ing of the perforations and the stop lug, together with the recesses having the radial walls with which the step lugs cooperate, in the fiat seating portions of the neck and the closure can they may be made by die=stainpihg at the same time, and tiius very accurately disposed relative to each other, so as to insure perfect alignment of the perforations for sifting and also most eificient positioning of the perforations for sealing the can.
It is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claim.
Having thus described the invention, What I claim as new and desire to secure by Letters Patent, is:
A sifter top can comprising a cylindrical neck having a closed end provided with a flat section extending across the neck substantially from one side thereof to the other and forming a seat for a closure cap, said flat section being provided with a series of spaced perforations adjacent the outer edge thereof and a series of depressions having spaced radially disposed endwalls located between the perforations and the center of said flat section, a rotary closure cap having a de pending skirt and a flat section in the top there of conforming to the flat section in the closure end of the neck, said flat section of the cap being provided with perforations adapted to register with the perforations in the end of the neck and an integral depending lug extending into each depression and adapted to enga e the radial en-iwalls thereof to limit the movement of the cap to insure registration oi-non-registration or said openings in the cap and neck, said neck having a retaining'bead formed therein and said 7' shift having the lower edge portion thereof curved to fit said head, said skirt being dimen sio'ned so as to be out of contact with the neck except in the regions of the retaining bead, said retaining bead and said curved portion of the skirt being disposed so as to hold the fiat sections in intimate contact while permitting the same to move relative to each other about the center of the cap.
