RECEPTACLE CLOSURE.

Application filed May 10, 1923. Serial No. 637,930.

To all whom it concern: Be it known that I, AUG STUS, L. ME- RoLLE,'a citizen of the United States, residing at Brooklyn, in the county .of Kings and in whichexceptionally strong and sub-' stantial thread elements are provided.

A further and more detailed object is to provide a closure of this type having a wire.- edge formed thereon by turning up the mavterial at the bottom of the flange, and said said wire-edge being indented to provide inwardly projecting lugs upon the flange for engaging beneath projections of the receptacle, and to form portions of the flange edge to comprise relatively resilient ribs rectly above said inset portions of the wirecontinuing thread-lik from said inset portions of the wire-edge whereby to insure uniform grip of the closure circumferentially of the receptacle.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention, and

' the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of this specification, and in which, I have shown merely a preferred form of embodiment of-the invention: y

Figure 1 is a side elevational view of a closure constructed in accordance with this invention, the same being illustrated as applied on to a receptacle and a part of the view being shown in vertical section for the disclosure of detailed construction.

Figure 2 is a detailed sectional View taken substantially upon the plane of line III-- III of Figure 1. I 1 I Figure 8-is a" fragmentary detailed view of a portion of the interior surface of the flange of the closure showing one of the thread portions and: I,

Figure 4 is a bottom parts seen in Figure 3.

Referring to the drawings for describing in detail the construction therein illustrated, the reference character L indicates the receptacle which is of course open at its up per end and which may or may not be provided with-anv annular outstanding bead 1 thereon spaced downwardly from the upper endfof the receptacle, Between the bead and the upper end is provided suitable outedge 'view of the standing threads or pro'ections 2 with which the closure is inten ed to engage by inter-rotation of said] parts in the usual manner. a

. The reference'character G indicates generally the closure device the salne being made up of a cover part 3 and an annular marginal flange 4 provided thereon for de-' ending about the exterior of'the receptacle. The entire closure is formed, from a single piece of sheet metal pressed, or drawn, into shape.

The lower annular-edge of the'flange is bent upon itself to'provide an outstanding wire-edge H. Above this "jwireredge the flange is provided with suitable corrugations 5 by which the closure may-begripped for screwing it onto and off of the receptacle. a

These corrugations are spaced above the wire-edge so as-to leavean expanse of the flange, as indicated 6, for carrying, the thread indentations 7.

There may be as many thread indentations circumferentially of the fla nge as desired. Ordinarily however fouraresuflioi'ent and it will of course be'understood that there is a similar number 'of the projections 2 formed upon the receptacle.

At the lower ends of each of the threadindentations, that is where said indentations meet the wire-edge H, said wire-edge s bent inwardly to rovide inset portions 8 directly in continuatlon of said thread indentations l and serving thereby as a'very strong and substantial reinforcement for the lower end of said thread indentations. They also 'provide smooth and attractively rounded ter- I minations of said'thread indentations. As a matter of fact, the thread indentations extend from a point above the wire edge in an inclined plane downwardly to and across the wire edge without interruption, the material of the wire edge at the lower ends of the thread indentations being bent bodily inwardly as a partof the thread indentations.

A most important characteristic to be noted in connection with this structure is that whereas the lower end, or beginning, of each of the thread portions of the closure is relatively strong and rigid, due: to the presence of the plurality of thicknesses of metal comprising the reinforcing band or wire-edge H, yet the portion of the thread above the wire-edge, comprisingas itdoes only a single thickness of metal, is relatively weak and resilient and is thereby capable of yielding to a certain and desired extent which will permit the several thread portions to assume uniform grip upon the receptacle when the closure is being rotated relative to the projections 2.

Although the upper portions of the threads are" relatively resilient yet they are efliciently held against undue spreading and the like by reason of the presence of the reinforcing band constituted by the wire-edge. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: s p

1. A receptacle closure comprising a cover portion and a flange portion, the material of the flange being bent upon itself to provide a wire-edge at the lower edge of the flange,

the materialof the flange being also bent to provide an inclined thread indentation therein, and said wire-edge being bent to provide an indentation standing as a continuation and constituent part of said thread indentation.

2. A receptacle closure comprising a cover portion and a flange portion, a wire edge formed upon said flange portion at the lower edge .thereof, thread indentations formed u on the flange portion being relatively resi ient above their lower end portions, and said wire edge having indentations therein arranged to constitute the lower ends of said thread indentations and to thereby render said lower ends relatively rigid and unyielding.

3. A receptacle closure comprising a cover portion and a flange portion, the material of the flange portionlbeing bent upon itself to provide a wire edge at the lower edge of the flange portion, the material of the flange portion being also bent to provide a thread indentation therein, and said thread indentation extending longitudinally in an.

inclined plane from a point spaced. above the wireedge downwardly across said wire edge, the material of the wire edge being bent bodily inwardly as a part of the thread indentation. r

In testimony whereof I aflix my signature.

AUGUSTUS L. MEROLLE.
