RECEPTACLE CLOSURE.

Application filed December 30, 1922. Serial No. 609,991.

To all whom it may concern:

Bev it known that I, AUeUsTUs L. lvlnnonnn, a citizen of the'United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Receptacle Closures, of which the following is a specification.

This invention relates to a receptacle closure, and an object of the invention is to provide a closure of the simple screw type and in which means is provided affording a. highly efficient linger grip for use in attaching and detaching the closure.

A further object is to provide a closure of this type having a wire-edge formed thereon by turning up the material at the bottom of the flange, and having specially prepared parts disposed adjacent to the wire-edge so as to reinforce the same against distortion and so as to cooperate therewith in provid ing an eflicient finger grip.

A. further object is to so form the material of the flange of the closure adjacent to the threads thereof as: to provide a desirable flexibility in said flange and threads so as to enable the threads to more readily acconr modate themselves to the threads 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 claim.

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

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.

Figure 2 is an enlarged detail sectional view thru a portion of the closure seen in Fig. 1.

Referring to the drawings for describing in detail the structure therein illustrated the reference character L indicates the receptacle which is of course open at its upper end and which is preferably provided with an annular outstanding bead 1 thereon spaced downwardly from the upper end of the receptacle. Between the bead and the upper end is provided suitable out-standing threads 2 with which the closure is intended to engage by interrotation of said parts in the usual manner.

The reference character G indicates generally the closure device, the same being made up of a. cover part 8 and an annular-- marginal flange 4 provided thereon for depending about the exterior of the receptacle. The entire closure is formed from a single piece of sheet metal pressed or drawn into shape, and the flange portion 4 thereof is pressed to provide the threads 5.

lt is to be particularly noted that the threads 5 do not extend'for the full width of the flange but that on the contrary they are confined to the central portion of the flange, i. e. to the region defined by the lines 6 and 7 in Fig. 2. The portion of the flange above the region of the threads, i. e. between the line (i and the top of the closure as defined by the line 8, is formed with vertically extending corrugations 9. While the portion of the flange below the threads. i. e. between the lines 7 and 10 is formed with a second series of vertical corrugations as 11. the wire-edge 12 which, as will be seen in the drawing is formed by bending up the material of the flange. The lower portions of the corrugations: 11 stand substantially in contact, with the upper portion of the wireedge and thus efficiently reinforce the wire-edge at all times.

The corrugations 1'1, projecting outwardly above the wire-edge also serve to protect said wire-edge against injury, and here it is to be noted, as shown by the line 13 in Fig. 2, that the corrugations 11 preferably extend outwardly to substantially the same vertical plane as the outermost portion of the wire-edgc so that in this way said corrugations 11 not only form a very eflicient protection for the wire-edge but also are given sufficient prominence so that they con stitute an elticicnt linger grip.

It is also to be noted that by corrugating and distorting the material of the flange adjacent to the lower portion of the threads there is provided a certain appreciable degree of flexibility and elasticity in said threads, and particularly in the lower por- Bclow the corrugations 11 is formed may-be correctly,definedtherefore as float- .ingubetween the upper and-lower portions of the flange.

:It is alsopdesired. to note that whereas the corrugations 11 are formed substantially holly byvibeing pressed outwardly beyond the normal plane of the-flange, said plane .being indicated byLthe, double dotted line 14 1; in Fig. 2,-thecorrugations 9;:are formed by pressing thematerialof the flange partlyoutwardofsaidfplane andpartly inward of said-plane. By this means the corrugations .11 are made-t0 project outwardly to a greater, extentthanthe corrugations 9 and a ;,correspondingand graceful upwardly taper- Also ing appearance is given tojthe-closure.

- by-setting the corrugations 9 inwardly a certain crowding of the material is felt --Which materially increasest-he elasticity and vflexibility zof the-flange in and near the threads.

, Any vsuitable gasket as 15 may be provided withinthe closure if desired for improving thesealing, as :will be understood.

As many changes could be made in this construction without departing from the scopeof the invention as defined in the following claim, it is intended that all matter contained in the above description or shown in the accompanying drawings, shall be interpretedas illustrative and not in a limiting sense.

Having thus described my invention, What I claim as new, andidesire to secure by Letters Patent. is

A receptacle closure-coinprising coverfiand flangeportions, the material of ;the flange being bentto provideithreads thereinspaced an appreciable distance downwardly from the upper edge of the flange -thematerial sol?,the,flaugeibeiughalso bent to provide an outstanding wire edgospaced. an. appreciable distance below; saidithreads, and the material of the flaugezbeing also bent to providezoor- .rugations extending vertically thereof. in

the spaces both above and below, said threads, all for the purpose set forth.

. In testimony-whereof, I aff x mysignature in the presence oftwowvitnesses.
