PRESSED-STEEL CONTAINER.

Application filed December 26, 1922. Serial No. 603,997.

To all whom it may concern:

Be it known that I, CARROLL BURTON, a citizen of the United States, and resident of Johnstown, in the county of Cambria and a State of Pennsylvania, have invented certain new and useful Improvements in Pressed-Steel Containers, of which the following is a specification.

This invention relates to containers and more particularly to metallic containers.

The object of the present invention is to provide a comparatively cheap, durable metallic container that will withstand the rough handling entailed in transportation, and also a container that may be used over and over.

A still further object is to provide a container having the novel features of design and construction hereinafter described in the following specification and illustrated in the accompanying drawings.

In the drawings, Figure l is a side elevation of a complete container.

Figure 2 is a transverse section taken on. the line 11-11 of Figure 1.

Figure 3 is a sectional elevation through a plurality of nested containers.

Figure at is a plan of the flat rectangular blank sheet from which the container is formed.

Figure 4a is a plan of the disk shaped blank out from the sheet of Figure 3 as the first step in the manufacture of the container.

Figures 5 and 6 are plan and side elevations, respectively, of the dished blank formed from the blank of Figure 4- during the manufacture of the container.

Figure 7 is a side elevation of th container formed by drawing the dished blank of Figures 5 and 6 through suitable dies.

Figure 8 is a plan View showing the slots formed in the rim of the container.

Figures 9, l0 and 11 are enlarged fragmentary views of the container showing the slot construction.

Figures 12 and 13 are detail views of the locking member adapted to be inserted in some of the container rim slots.

Figure 14 is a plan of the container cover blank.

Figure 14 is a plan of the container cover or closure blank formed from the blank of Figure 14.

Figures l5, l6 and 16 are enlarged fragill nientary detail views of the cover or closure showing the bayonet locking lugs.

Figure 17 is a partial vertical section through a container having a slightly modified construction.

Referring particularly to Figure l, the container shown is composed of a body portion A and closure B. The body portion A is formed from a single piece of metal and comprises a flat base or bottom portion 2. side walls 3 having reinforcing ribs 4. and top rim 5. The side walls are expanded upwardly so as to form the container with a slightly greater diameter at its upper end than at its bottom to permit nesting of the containers one within the other when empty for storage or shipping (see Figure 3).

The reinforcing ribs at are formed by overlapping or folding the side wall metal upon itself so as to form a multiple thickness of metal at these points and thus stiffen the container and prevent collapsing thereof.

The ri1n5 is provided with a plurality of slots 6 and 7 (see Figure 8) for the reception of locking or securing lugs on the closur B. The slots 7 have an oifset portion at one end. The metal cut from the rim 5 in forming the offset portion of the slots 7 is not detached from the end of the slot but is bent down into the rim and provides a stop member 8 for a purpose to be described (see Figures 9 and 10).

The top or closure B is formed from a single piece of sheet metal and is cut to size to lit over the rim 5 of the container. The top is provided with a plurality of L-shaped lugs 9 at spaced intervals around its periphery which extend downwardly on an angle from the edge of the closure. The lugs 9 are adapted to be inserted in the slots 6 and 7 and be turned until their shanks strike the end of the slots.

Spring keys or rings 10 are adapted to be inserted in the offset portion of the slots 7 and to bear against the stop 8 and the lug 9, thus preventing accidental displacement of the closure.

The method of making the containers described above is as follows-The disk shaped blank 15 of Figure 4* is sheared or otherwise cut from the flat sheet steel plate 16 of Figure 4. The disk shaped blank 15 of Figure 4 is then passed between fluted conical rollers or otherwise worked to form the dished blank 17 of Figures 5 and 6, which ill has a flat bottom and crimped side Walls. The crin'ips 18 in the side walls of the blank 1'? are formed with one narrow and one Wide side so that they may be flattened or folded back upon theinselres.

The dished blank 12' o Figures 5 and 5 is then drawn in a press through suitable dies and guides to fold and flatten the crimps 18 back upon themselves and torxn the substantially vertical side Wall 3 or the container and e wedge shaped reinforcing ribs l (see Figure 7). As the draivi operation is completed a 5 iitable press other inl i will be ciuployed to pres:

out or turn the lip or rini 5 on the upper l the container.

I ,ortionl The in a suitable p i ning the sl b and T 7 aiaced in a d i n r 1 i (l ipletely lo i'orni a substantially circular (sec 9 and ill t inn" the be uurtion o.

.lhe chew-are l3 oi the container is 4 1 a blank it), and the 3 it 2i shown in if sheared from the blaul: 21 is then passed through a suitable pr: to bend the lugs (3 and 7 of rr Or the container.

In Figure 1'? I havshown a partial vertical section of a cent or con. 'ructed in accordance with this invention and identical to the \onstru J u in all iespeci But having as an adde' turc a reinforcing ring secured in the lower fillet ot' the ontaiuer and serves to prevent bending or enting of this portion.

1 the above it will be readily apprer rein elated that I have devised a new and novel method for making a note pressed steel container that is durable and useful. Containers made as herein described may be used as bolt and nail containers, and for other uses Where they are subject to hard danger of breakage or outw'ai'oly turned riin around the upper c e of said container having a plurality or slots therein, a'tlat disk like closure for said downwardly projecting lugs on said closure adapted to project into the slots in said rim and engage said riin when said closure is given. a slight turn, and means inserted in some of said slots adapted to engage said rim and said L-shaped lugs to prevent the removal or said closure.

A metallic container comprising in combination a body portion composed of a single pieceol" metal and having a fiat bottom and circular side Walls, said side Walls expanding slightly upwardly so as to perniit nesting oi the containers one Within the other, a series of vertical reinforcing ribs disposed at intervals around said side walls composed of multiple thicknesses of the side Wall metal, an outwardly turnedhollow llll) having a' substantially circular cross section and I slots, a fiat disk-like closure for said container, a plurality of L-shaped downwardly projecting lugs on said closure adapted to project into the slots in said rinrand engage said riin when said closure is given a slight turn, and resilient means inserted in at least one oi said slots to engage the rim and L- shaped lug" to prevent the accidental removal of said closure.

In testimony whereof I have hereunto setmy hand.
