oovnn FOR CANS Ann mum's Application filed July 2, 1926. SeriaI No. 120,028. 3

This invention has relation to covers for cans, receptacles, or the like, made of metal, and more particularly cans such as are employed as containers for handling and shipping frozen eggs.

A wooden cover is usually employed for closing such cans, the interior surfaces of which are lined with sheet metal. The practice has been to fix the lining by nailing it to the sides of the cover, and to fasten the cover to the can by nailing strips of flexible metal at regular intervals to the marginal portion of the cover, andthen to tuck or engage the free end portion of the strip in between a downwardly turned bead and the upper edge portion of the can. Such practice is disadvantageous, from the fact that the strips are nailed to the cover, as, in handling and transportation, the nails are liable to work'loose and allow the cover to become loose or unfastened, and from the fact that individual fastening elements are used for retaining the lining in place on the cover.

In accordance with the present invention, therefore, the strips or elements which are utilized for inter-engagement with the can are formed integral with the lining of the cover, so that the nailing operation is dispensed with and a more permanent securement of the cover to the can is afforded and the lining is retained in place on the cover without the need of individual fastening ele ments, by spinning it over onto the top'face of the cover.

On the accompanying drawings, Figure 1 is a section through a side of a can, showing the head at the rim thereof.

Figure 2 represents a plan view of a cover embodying the present invention, fastened to the can.

Figure 3 illustrates a section on the line 38 of Figure 2.

Figure .L is an enlarged plan view of a portion of the cover, showing a cover fastening element. I

Figures 5 and 6, respectively, show detailed sections on the lines 5-5'and 6-6 of Figure 4.

connection with which the cover of the pres i i ent inventionis used. In actual practice, the cans may, for example, beabout 12 inches in: height and about 10 inchesin diameter, orof any other commereial size. The const ruc-i tion of the can, however, forms no part of the present invention,except insofar as it isin combination with the cover; r Y 'At the upper edge of the'ca'n,the metal is bent downwardlyand thence. upwardly in the formwof a head 2, of doublezthick'ness, which abuts, against the rim. 1 The head constitutes the element of the can forinter-em gagement with the fasteningelements of the cover. Any other suitable beadconstruction may be i used, if desired.

:The cover 8, as shown, is made of ,wood, I

and is of the proper size to fit Within the can opening. The cover is interiorly lined with sheet metal, which overlies 'itsinteriorsurface and side and 1s securedto the cover by a flange 4 which is'spun over onto the top 01' moreover, fastening elements '5, are formed integral with the liningof the cover, preferably at regularly spaced intervals, as at each quadrant. at the margin thereof. Each fas-, toning element is in the form of a strip, the free end of which is folded back on itself to form an engaging element 6 of double thickness, thereby strengthening the element and giving an edge 6 against which a suitable tool may be caused to act.

The cover is secured to the can by tucking the element 6 in between the bead2 and the seam of the can, as shown in Figure 5, there by prying the seam away from the upper edge portion of the can at'the desired intervals, and eflt'ectinginter-engagement of can and cover.

By the practice of the present invention, the use of individual. fasteningelements is eni I i In accordance With thepresent invention,

tirely done away with, both in securing the lining to the cover and in fastening the cover to the can, producing thereby a more economical and effective package.

Having thus described an embodiment. of this invention, itshould be obvious that it is susceptible of various changes and modifications without departing from its spirit orv scope as defined by the appended claims.

I claimzjl V. i

1. The combinationwith a can, of a wooden cover for closing said can having a metal lining covering the interior surface thereof and secured thereto by a flanged marginal portion of said lining spun over the exterior surface thereof and projecting exteriorly from the marginal portion of the cover and resting on the upper edge of said can.

2. The combination with a can having an exterior bead at the upper edge portion thereof, of a wooden. cover forclosing said can,

havinga metal lining covering the interior I surface thereof and a-series of spaced fastening elements integral With said; lining and inter-engaging with the bead of said can.

3. Thecombination with a can having an exterior bead at the upper edge portion thereof, of a wooden'cover for closing said can having a metal lining covering the interior ao surface thereof and secured thereto by a flanged marginal portion of said lining spun over the exterior surface thereof, and a series of spaced marginal fastening strips integral with said'lining and inter-engaging with the 'bead of said can;

4. The combination witha can having an exterior bead of double thickness at the upperfedge portion thereof of a wooden cover for closing said can having ametal lining m -covering the interior surface therof and secured thereto by a flanged marginal portion of said lining spun over the exterior surface thereof, and a series of fasteningstrips spaced about the margin of-saidcover and integral 1-3with said lining inter-engaging with the bead of said can the inter-engaging portion of said strip being of double thickness and presenting an edge against which a tool may be brought.

In testimony whereof I have affixed my signature. I
