To all whom it may concem Be it known that I, L. Wnrssnnmanner, a citizen, of France, and resident of Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Sheet- MetalClosures, of which the following is a specification. I
This invention relates to closures for jars and similar vessels, having relation" more especially to that type of closures in which a single piece of sheet metal is struck up to form a crown portion having an integral depending circumferential flange which is pro vided at intervals with inward projections which are adapted to be engaged with and disen aged from inclined or spirally-dispose rlbs or threads exteriorly of the neck of a jar or the like.
The object of my invention is to provide a closure-of the type mentioned, which may be economically constructed of relatively thin metal and yet shall possess ample strength and rigidity together with suficient resiliency to insure its ready application to and eficient locking engagement with the projections or threads of the vessel to be sealed, and this irrespective of ordinary structural imperfections of the interlochng parts.
According to my invention the closure. in its preferred form'is so constructed that its lower edge presents a series of relat1vely thin inturned locking projections the ends of which merge with and form acontinuati'onof an inwardly and upwardly bent and pressed rim portionof the flange, whereby the material in the spaces between the looking projections is reinforced without increasing the body or thickness of the thread engaging portions of such projections and without'impairing the requisite reslhency of the flange.
The precise nature and scope of my 1nvention will appear from the following description and claims.
In the drawings-Figure 1 is a side elevation of my improved closure as applied to the mouth of a jar. Fig. 2 is a transverse vertical section of Fig. 1. Fig. 3 is a bottom view of the closure. Fig. 4: is a trans verse section thereof, as on the line H of Fig. 3. Fig. 5 is a similar section as on the line 55 of Fig. 3. Fig. 6 is a similar sec tion of the closure showing the inturned and pressed upwardly to provide a reinforced segmental rim portion 12 having thin inwardly-projecting teats 13 which constitute locking projections. The segmental portions of the inturned edge are pressed hard against the inner side of the flange,
and the ends of such members are caused to merge directly with the proximate ends of the-inwardly-projecting teats so as to support and brace the latter without increasing the body or thickness of their free thread-engaging edges. In the present instance-the flange is represented as provided with four locking projections of the character described, but it is to be understood that a greater or less number of such projections may be employe Preferably the flange of the closure is provided with vertical corrugations, as 14, which tend to stiflien the structure and also provide a knurled finger hold therefor as usual, the inner and outer convex portions of the corrugations being'flush with the adjacent surfaces of the reinforced rim of the flange.
'Bythe construction above described the external appearance of the closure is practically unafl'ected by the presence of the reinforced rim and the locking projections, for the reason that the edge fold is on-the interior of the flange and the basal portions of the projections are flush with thelower edge of the rim or substantially so. The projections 13 being relatively thin and in close relation to the edge of the rim readily ltd are pro-(lace We bfmk of the requisite diameter. I then shape the blankto produce the crown 18 and the depending flange 11. I then turn the lower edge 6fof the flange by inwardly and upwardtvbent rilii portions which merge with and brace theend's oi the said projections.
2. A sheet metalclosure whereof the flange i provided at its lower edge with a thin inturned locking projection and with an inwardly and upwardly bent and pressed rim portion which merges with and forms a co ting tionof e ends of said projection. lgne at New ork in the State of New York this thirteenth day of February A.
