Application led December 4, 1915. Serial No. 65,016.

To all whom t may concern.

Be it known that I, ROBERT HULME, of Memphis, in the county of Shelby and State of Tennessee, have invented a new and Improved Receptacle-Cover, of which the following is a specification.

The present invention relates to a cover for receptacles containing material such as is apt to spoil or deteriorate in quality unless kept tightly closed, and is particularly designed for use with cans containing lard or lard substitute, best known in the trade as lard compound.

The objects of the invention are, to provide a cover which will it so securely upon the receptacle as to insure its staying in place duringtransit; which will make the receptacle substantially airtight; which may be easily removed; and whichy can bereused severalcapacities.v

The .improvements are illustrated accompanying drawings, "wherein- Figure 1, is a cross-section of the cover provided with the present improvements. Fig. 2, is a side elevation of the cover. Fig. 3, is a top view of half the cover. Figs. t and 5, are'enlarged cross-sections of part of the y the cover.

tance between the The cover A, is of sheet metal and is adapted to be used in connection with a receptacle which has at its top an out-turned rim or ring. The cover has annular corrugations therein, illustrated at B, for the purpose of strengthening it.

At its outer edge, the cover is provided with a rim extending entirely around it having an annular groove D, fitting closely around the upper portion of the outwardly projecting rim of the receptacle, as shown in Fig.` 5, and formed by the inclined inner wall E, and the outer down-turned flange I. This flange I, extends around the entire lcover outwardly and downwardly from the upper edge of the inwardly extending friction wall E, and has therein an` initially formed, permanent inward bend F, extending partly beneath the rim of the receptacle, below which is an outwardly flaring skirt K, projecting beyond the body of the receptacle,

and ending in an upwardly and outwardly turned curl Gr.l

The distance between the permanent inward bend F, and the nearest point of the inclined inner wall E, is less than the dispoints H and I, in Fig. 4,

which are located above the inward bend F.

The portion of the groove D, between the points H and I, is so formed as to lit and closely hug the rim of the receptacle. As will readily be seen, when the rim of the receptacle'is forced past the inward bend F, into the socket between the points H and l, the ange springs over the receptacle rim and the inward bend extends partly beneath theareceptacle rim so that the cover is held securely in place by friction, and by clenchlng.

The purpose of the outwardly flaring skirt K, is to form a lead for guiding the rim J, of the receptacle into the groove D, while the curl G, strengthens the outer wall of the groove so that it can readily withstand the tapping which is necessary to release the cover from the friction grip.

The inwardly extending friction wall E,

i of the groove D, lits snugly against the inner inclined surface or wall of the receptacle thus making the receptacle substantially airtight when the cover has been forced past the friction grip.

Below and inside the inner wall E, from the points L to M, the cover tapers abruptly toward the center of the receptacle for the purpose of aiding or guiding the cover in centering itself upon the rim of the receptacle, and joins the friction wall E, to the body of the cover.

When it is desired to place the cover onthe receptacle, the handle C, is taken hold of and the cover placed over the receptacle. The taper beginning at M, in conjunction with the skirt K, causes the cover to slip easily in place and close the opening in the receptacle. Then in order to make the cover fit airtight, which is necessary for shipping purposes, downward pressure is brought to bear upon the rim of the cover thereby forcing the rim down past the friction points F, and the nearest point on the inclined inner wall E, thus making the receptacle substantially airtight and the friction being sufficiently strong to insure the cover remaining 1n place during transit, and at all times' without destroying it or its effectiveness in any` respect.

he rim of the cover extends entirely around it so that the inwardly extending friction wall fits the inner wall of the receptacle all the way around, and between the outer flange and the friction wall there lis a continuous groove into which the receptacle rim fits closely throughout its entire periphery. Likewise, the inward bend extends circumferentially so that when the cover is sprung on to the receptacle rim the bend extends beneath said rim all the way around the receptacle,

I claim- 1. A receptacle having an outwardly projecting rim, in combination with a sheet metal cover having a rim extending entirely around it and comprising an inwardly extending friction wall adapted to fit the inner Wall of the receptacle all the way around, an abruptly inwardly inclined guiding wall below said friction wall and )oining the friction wall to the body of the cover, and an outer flange extending outwardly and downwardly around the entire cover from the upper edge of said friction wall with a continuous groove between said friction wall and said flange into which the upper portion of the receptacle rim throughout its entire periphery fits closely, and said outer flange having a circumferential permanent initially provided inward bend spaced from the body of the receptacle a less distance than the projection of the receptacle rim so that Iwhen the flange is sprung over such rim said inward bend extends partly beneath such rim, 'and said outer flange further having acircumferential skirt at its bottom below said bend and spaced outwardly from the bod of the receptacle and terminating in a sti ening curl.

2. A receptacle having an outwardly ro- ]'ecting rim, in combination with a slieet metal cover having a rim extending entirely around it and comprising an inwardly extending friction wall adapted to t the inner wall of the rece tacle all the way around, and an 'outer ange extending outwardly aliddownwardly 'around the entire cover from the upper edge of said friction wall with a continuous groove between said friction walland said flange into which .the upper portion of the receptacle rim throughout its entire periphery fit-s closely, and said outer flange having a circumferential perpartly beneath such rim,

miams manent initially provided inward bend spaced from the body of the receptacle a less distance than the projection of the receptacle rim so that when the flange is sprung over such rim said inward bend extends and said outer flange further having a circumferential skirt at its bottom below said bend andspaced outwardly from the body of the receptacle and terminating in a stifl'ening curl.

3. A receptacle having an outwardly projecting rim, in combination with a sheet Ametal cover having a rim extending entirely around it and comprising an inwardly extending friction wall adapted to t the inner wall of the receptacle all the way around, and an outer flange extending outwardly and downwardly around the entire cover from the upper edge of said friction wall with a continuous groove between said friction wall and said flange into which the upper portion of the receptacle rim throughout its entire periphery fits closely, and said outer flange having a circumferential permanent initially provided inward bend spaced from the body of the receptacle a less distance than the projection of the receptacle rim so that when the :flange is sprung over such rim said inward bend extends partly beneath such rim, and said outer flange further having a circumferential skirt at its bottom below said bend and spaced out wardly from the body of the receptacle.

4. A receptacle having a flaring mouth and an outwardly projectingrim, in combination with a sheet metal cover having a rim extending entirely around it and comprising an inwardly extending inclined friction wall adapted to fit the inner wall of the flaring mouth of the receptacle all the way arou'id, and an outer flange extending outwardly and downwardly around the entire cover from the upper edge of said friction wall with a continuous groove between said friction wall and said flange into which the upper portion of the rece tacle rim throughout its entire periphery ts closely, and said outer flange having a. circumferential permanent initially providedfinward bend;v spaced from the body of the receptacle a less distance than the projection of the receptacle rim so that when the flange is sprung over such rim said inward bend extends partly beneath such rim.
