CONTAINER Filed Ju ne 19. 1928 INVENTEIR HTTEIRNEY Patented Mar. 25, 1930 v UNITED STATES PATENT OFFICE HENRY KIELIBERG, OF MARTIN S FERRY, OHIO, ASSIGNOR TO WH EELING STEEL CORPO- RATION, OF WHEELIN G, WEST VIRGINIA, A CORPORATION OF DELAWARE CONTAINER Application filed June 19,

This invention relates broadly to headattaching devices for cans and pails, and it has forits primary object to provide, in association with a removable head or cover for cans and pails, a ring whereby said head or cover is secured in firmly seated closing relation to the can or pail.

A further object is to provide an attaching ring of the character mentioned which may be readily removed when access to the contents of the can or pail is desired.

In describing the invention in detail, reference is herein had to the accompanying drawings, in which-. igure 1 is a perspective viewfof the in vention;

Figure 2 is a view ofa can or pail, partly in side elevation and partly insection, showing the invention applied thereto; Figure 3 is an enlarged detail view, showing in side elevation the two ends of the ring in detached relation; v

Figure 4 is a similar view showing said ends attached, as in Figs. 1 and 2;

Figure 5 is a View similar to Fig. 3, illustrating a modification; andt Figure 6 is a view similar to Fig. 4, showing said modification. Referring to said drawings, 1 designates the body of a can or pail of the type commonly employed as containers for paints and other heavy materials, the same having at its upper 5 end an outwardly turned terminal bead or roll 2.

Mounted upon said can or pail is a head or cover consisting of a flat body 3 which fits withinthe top of the body 1 and a circumferential marginal portion or rim 4, the latter being curved upwardly and outwardly to seat conformably upon the top of the roll 2, as shownin Fig. 2.

Disposed in'closely embracing relation to the outer circumferential surface of the roll 2 and to the outer edge portion of the rim 4, seated as aforesaid, is a sealing ring 5, arcuate in cross section, which is formed of a single length or strip of sheet metal having its ends rigidly attached one to the other. The arcuately curved body of said-ring has depending from the lower edge thereof a plu- 1928. Serial No. 286,623.

rality of integral lugs or tongues 6 which are adapted, following seating of the ring in place, to'be turned inwardly into underlying seated'relation to said roll, whereby the cover is clamped in its seated position.

Said sealing ring has in one end thereof an H-slot formed by the provision of a pair of transversely extending relatively spaced parallel slots 7 which are joined midway be-' tween their ends by a cross slot 7", thereby forming oppositely facing tongues 9. Prior to attaching the two ends of the ring, said tongues 9 occupy outwardly bent positions wherein they are substantially parallel.

The opposite end of the ring has its top and bottom edges recessed at opposite points, as shown at 10, thereby forming a reduced neck portion, indicated by the reference character 11, having a vertical width somewhat less than the vertical width of the substantially rectangular opening which is presented when the tongues 9 are outwardly turned, as hereinbefore described. The portions of the top and bottom edges of the ring located between the recesses 10 and the terminal edge of the adjacent end constitute tongues 12 which, prior to joining the two ends of the ring, occupy inwardly directed substantially parallel relation. Thus, when said end of the ring is placed in overlapping relation to the opposite end, its said tongues 12 are readily entered through the opening of the overlapped end, following which the tongues 9 are bent down into seated relation to the overlapping end. The tongues 12 are then expanded into seated underlying relation to the interior walls of said overlapped end, as shown in Fig. 4.

. The ring, shaped as in Fig. 1, is preferably sprung or pressed into closely embracing relation to the rim 4 of the cover 3 before shipment from the factory. In such relation the ring is self retaining with respect to the cover and requires only that the packer, in closing the can or pail, seat the cover and ring in the manner of a single element to such can or pail and then to tuck the lugs 6 into closely underlying relation to the roll 2 for securing said cover in place.

The advantage of the structure hereinbefore described, involving the separately ormed cover and ring, over prior structures 1n which the seating or clamping lugs are formed integral with the cover, is that the ring may readily be broken across at the neck 11, following which it may be stripped off by pulling upon one or the other of the ends; whereas,'with the prior structures" referred to, it is necessary that all of the clamping lugs be separately bent away from their seated relation to the'roll of the body. J

, It will be noted that, following removal of the ring, as aforesaid, the'cover is in no wise injured and may be reused from time to time,

. as may be required.

In the modifications lllustrated in Figs. 5 and 6, the overlapping end of the ring is extended in the form of a tongue 13 having any suitable length, and said tong e is adapted to have its end directedthroug a transverse slot 14 provided therefor in, the overlapped end of the ring at an appropriate distance from the H-slot; F

Q What is claim is -1. A sealing ring for containerscomposed of a strip having an opening adjacent one end and having oppositely disposed tongues at the ends of the opening, the other end of r the strip being of reduced width and received in said opening and having oppositely disposedtongues 1n a plane parallel to and in register with the plane of the first named tongues and bent outwardly to engage the inner face of the first named end of the strip,

5 the first named tongues being engaged over the outer face of the reduced end of the strip.

2. A- sealing ring for containers composed of a strip having an opening adjacent one end and having oppositely disposed tongues at' 0 the ends of the opening; the other end of the strip being of reduced width and received in said openingand having oppositely disposed tongues bent to engage the inner face of the first named end of 'the strip, the first named tongues being engaged over the outer face of the reduced end of the strip. 1
