(Cl. 220—59) groove [2 is formed beyond the bead II. The closure is preferably drawn from ?at sheet metal This invention relates to a closure for con tainers such as drums, pails or the like and, in particular, to a cover which is inexpensive‘ to manufacture and capable of being ?rmly secured stock in suitable drawing dies. The groove or channel I2 is adapted to receive the false wire of a' container when the closure is placed thereon. Figs. 7 and 8 show a container [3 having a false . 5 to the container. Container closures of various types are now in wire 14 surrounding an opening therein or an. use, but each is characterized by certain objec tionable features. Certain closures have been’ open end thereof. provided with a s'o-called “ring type” seal where The outer side or wall l5 of, the channel [2 is in a ?anged cover is secured to a container by provided with cut-outs I6. These cut-outs are 10 a frangible clamping ring. or channel. While ‘ preferably spaced inwardly of the extreme edge of the ?ange formed by the wall l5, and the this is a very effective form of seal, it is rela tively expensive. Lug-type closures have also material between the edge of the ?ange and the been used but have been found lacking in effec cut-outs is slightly displaced out of its normal 15 tive sealing qualities. A further objection is that plane forming loops ll. The cut-outs are pref the operation of bending theholding lugs often ' erably triangular in shape as shown, having one mars the finish on the container which is edge parallel tothe edge of the ?ange or wall undesirable. I g l5, for a purpose which will appear later, but -. - may be simply slits parallel to the ?ange edge. I have invented a closure which overcomes the 20 aforementioned objections to such articles as pre viously manufactured. The closure may be applied to a container as 20 In accordance with. my already indicated and, if desired, a sealing gasket invention, I provide a closure comprising a cen tral or body portion surrounded by a pressed may be disposed in the groove I2 for engagement with the falsewire Hi. When the cover has been groove or channel adapted to receive the false 25 wire around av container opening when the clo seated on the container and pressed'down tight ly, the edge of the ?ange or wall I5 is bent around the false 'wire, as shown inFigs. 7 and 8. sure is placed thereover. The extreme edge of the closure, i. e. the outer wall or side of the groove or channel,‘ is provided with cut-outs which facilitatecrimping the edge around the 30 false wire. Preferably, the cut-outs are spaced inwardly of the edge of the closure, and the ma This operation crimps the edge of the ?ange l5, partly closes the triangular cut-outs l6, and in creases the extent to which the loops I‘! are dis placed from the normal plane of the ?ange 15. 30 It will be observed that the extreme ‘edge of the. terial between'the cut-outs and the closure edge . ?ange l5 clears the side wall of the container is displaced slightly from its original plane.

A downwardly dis placed bead ll surrounds the central portion I0, and contributes rigidity thereto. A channel or for cooperating therewith. In addition, it is more effective in sealing'a container‘ than a lug-type 50 cover, and the application thereof to the con tainer does not mar the ?nish on the latter. Although I have illustrated and described but one preferred form of the invention, it will be ap parent that changes therein‘may be made with 65 2,137,076 out departing from the spirit thereof or the scope of the appended claims. I claim: 1. A container closure having a continuous down-turned peripheral ?ange, holes spaced along said ?ange and inwardly of the edge there of, portions of said edge being bent outwardly of the general plane of said ?ange adjacent said holes only. 10 , ‘ 2. A container closure having a continuous down-turned ?ange adapted to be curled around the false wire of a container, holes adjacent the ?ange edge forming lugs therebetween capable of bending inwardly without interference with each other, the edge of the ?ange being continu 15 ous across said holes, but bent out of the general plane of the ?ange adjacent the holes. 3. A container closure comprising a body portion and down-turned ?ange thereon, with perforations spaced slightly from the ?ange edge, the edge being deformed outwardly adjacent the perforations only. 4. The closure de?ned by claim 3 character ized by said perforations having an edge parallel to the edge of said ?ange. ‘ 5. A sheet metal closure comprising a central portion, a peripheral groove or channel, and per 10 forations adjacent the outer edge of the groove, but spaced slightly therefrom, the edge of the closure being displaced from its initial position adjacent said perforations to facilitate crimping said edge around; the false wire of a container. 15 GUY O.
