momes PATENT oFFlcs CHARLES GUERITEY, F PASSAIC, NEW JERSEY sirrme 'for CAN Application illed August 16, 1927. Serial No. 218,336..

This invention relates to cans or similar receptacles for holding material in powdered l form, the construction being such that this material may be either sifted out through perforations or poured out through a large ouring opening. Various constructions have been provided for such receptacles whereby a slide is applied to the top, which' in one position permits of sifting out the contents and in another position permits of pouring out the contents, and in a third po,- sition closes the respective 4openings, so that the contents are confined. The present invention provides certain improvements 1n cans or receptacles of this character. y

According to this invention the slide is imperforate'and the can top is formed with two openings, the one a large pouring opening and the other a sifting opening, consist- 2o ing of a group of perforations; these respective openings are arranged close enough together to be covered by the slide in its normal mid-position; the slide is movable to either side so that moved in one direction it uncovers the sifting perforations and moved in the other direction it uncovers the pour: ing opening. Stops are formed to limit these respective movements of the slide. The openings are formed in a portion ofthe can top which is either-'elevated above the seam which unites the top'to the can'body or at 'least is no lower than the top of this seam;

the slide is extended laterally and passes freely over the'top of the double seam, which.

latter as usual is formed to project exteriorly and the slide is thenA bent down'` on each side to embrace the seam and turned underneath the seam. This 'construction gives a resilient lengagement between the slide and the can'top, such as holds it irmly in any position, while yet permitting it to be freely slid from one position to another. The can top instead of being recessed is extended at least flush with the seamed -top of the can or preferably slightly above that level, so that no hollow is afforded for collecting' dust.

The improved .construction is shown in the accompanying drawings, wherein,

Figure 1 is a perspective view ofthe improved receptacle.

*.ln the usual manner by a double seam a.

The bottom C is similarly united to the body' by the usual double seam b or in any other 05 wayf D is the slide which is simply a band of metal passing across the top of the can top and havin its side portions c turned down close against the outside of the seam a: and beni; under it at d. The portion o is 70 corrugated or knurled to give a better hold for shifting the slide.

The can top B is formed with its main portion e preferably ona level with or at least not materially lower thanthe top of 75 the seam a; and with a portion f which is slightly raised above the portion e. This portion f is formed with a pouring opening g and with sifting perforations h, the latter constituting collectively a sifting opening. so The slide D lies in a plane close above the elevated portion f of the c antop, as best shown inFig. 5, and is thence extended lateally to .meet the downturned portions c. This lateral extension may be perfectly fiat, ,as.shown, orit may more or less approach y the level of the portion e, but should in any event pass clearly and freely over the top of the double 'seam z. It results from this construction that the portion of the slide D indicated at i in Fi` 5 which extends over the general level e o the can top and between Cthe raised portion f and the downturned side portions c of the slide constitutes a' sort of resilient bridge whereby in cooperation with the underturned portions d the slide is held' down in place to form a tight fit over the perforated portion f, so as to tightly close the openings and at the same time to form a lyielding engagement with the side seam a which constitutes its slideway. Heretofore such slides have been made to closely fit around the seam, embracing it at both top and bottom, a construction which is liable to generate too much friction, particularly after a can has been long held in storage, so that the metal has become slightly corroded. My improved construction is not affected by any slight corrosion resulting from storage, and the slide is enabled to work freely at all times, while yet having suficient cling tothe can top to hold it securely in any position in which it may be left.

In case the flanged portions c, d, of the slide become stuck fast, the resilient bridges z' enable the operator, by pressing down the outer portions of the slide, to free them from any adherence to the seam; the space between the top of the seam and the under side of the slide being suliciently wide to enable pressure thus applied to force the underturned hooked portions d away from the seam; thus the slide may easily be restored to free sliding relation.

The openings, g, h, are close enough together and the slide D iswide enough so that in the middle position of the slide both openings are closed. s When it is desired to pour the contents from the can, the slide is pushed to the left, as shown in Fig. 2, thereby uncovering the pour hole g. When it is desired to sift out the contents the slide is moved to the right, as shown in Fig. 1, thereby uncovering the perforations it. These opposite movements of the slide are limited byfstop projections E E which are bent up from the otherwise level top of the can slightly above the slide.

In the construction of the can the can top and body are seamed together in the usual way. At this time the can top is devoid of the stop projections E E. The slide D is then applied by slipping it over the can top from one end. Then by inserting a suitable die or punch within the can body the projections E E are struck up; this retains the slide and prevents its being disconnected` from the top. Then with the slide in its intermediate position the can is turned bottom side up and lled with powder through its open bottom. Thereafter .the bottom head is applied and seamed on to the body in the customary manner.

Heretofore cans of this general type have usually had the top depressed to a level of about that of the lower portion of the double seam. This leaves a hollow or depressed portion in the can top which in the case of goods which stand long on a grocers shelves, for example, is liable to accumulate dust and present an unsightly appearance. Because of the dust lodging in this recess it is impossible to wipe it off and it is generally impracticable to turn over such a can to the purchaser in neat condition after it has been held a considerable time on the shelves.l

The present invention avoids this disadvantage by forming the can top with its portion e substantially flush with or not materially lower than the top of the double seam. This involves a somewhat unusual construction in that the metal of the can top inside of the seam (which usually is carried inward in the position shown by dotted lines in Fig. 5) is bent upward at y' to a height substantially equal to the top of the double seam, and is then carried inward on the level e. The portion y' is bent in so close to the double seam as to leave only an extremely narrow crack between, which is too thin to admit any appreciable amount of dust. The result is that the can top appears to be and is substantially flush with the top of the seam, so that there is no opportunity for the accumulation of dust in a position where it cannot be readily wiped or brushed off.

The construction shown is that which is preferred, but this may be somewhat varied within the limits of the appended claims.

IVhat I claim is:

1. A receptacle having its top doubleseamed to its body, the top having openings, and the portion of the top formed with such openings raised above the bottom of such seam, and a slide having its' middle portion lying close above the said portion of the top to close 'one or more of said openings accoi-ding to its position and having resilient lateral portions extended freely above said seam and bent down against and under said seam to resiliently embrace the seam,

whereby they may be sprung down to release their cling under said seam.

2. A powder receptacle having pouring and sifting openings in its top, and the top and body united by a double seam, the top formed substantially flush with the up er part of such double seam to avoid the ormation of a hollow or recess in which dust may collect.

. .3. A receptacle for powder havin sifting and pouring openings in its top an the top' double seamed to the body, the top formed with an upward bend closely ad] acent to such seam, whereby the main .part of the top is elevated to a plane substantially flush with the top of the seam. ,f

4. A receptacle for powder having its top double-seamed to 'its body, the top having openings, and the portion of the top formed with such openings raised above the level of such seam and a slide having its middle portion lying close above the said portion of/the top to close one or more of said openings according to its position, and having its lateral portions extended freely beyond such elevated top and above the top of the seam, and bent down against and under said seam to form a sliding fit with the latter, the

space between the top of the seam and the bottom of the slide enabling the resilient lateral portions of the slide to be pressed down to separate its under portion from theseam, whereby to keep the parts in sliding relation.

5. A receptacle having its top formed with an opening inthe form of perforations for sifting, and having a large opening for pouring and a slide movable to three positions to open either or close both of said openings, the receptacle having its top seamed to its body, and the slide having resilientl lateral portions extended freely above said seam on both sides and bent down against and under said seam to resiliently embrace the seam, whereby they may be sprung down to release their cling under said seam.

In witness whereof, I have hereunto signed my name.
