CONTAINER Filed June 19, 1928 INVENTEIR HT T'EIZNEY Patented Mar. 25, 1930 v UNITED STA TEFS PATENT. OFFICE HENRY KIELBERG, OF MARTIN'S FERRY, OHIO, ASSIGNOR TO WHEELING STEEL CORPO- IR'ATIOIY, OF WHEELING, WEST VIRGINIA, A. CORPORATION OF DELAWARE CONTAINER Application filed June 19,
I can or pail and means for attaching a head or cover thereto.
Theprimary object of the invention is to provide a can or pail of the character commonly employed as containers for paints and, other liquids or semi-liquids, having a removable cover and associated novel and improved means whereby said cover may be secured in closing relation to the container.
A further object is to provide a cover for cans and pails having associated therewith a sealing ring whereby'it may be rigidly securedin place and which may be bodily, re-
moved with a minimum of eflortand without injury to or bending of any part of the cover, thus adapting said'oover for frequentre-use.
A still further object is to provide a sealing ring which may be sprung or pressed upon the cover in self-retaining relationgtothe latter by the manufacturer, thus to ad pt said ring and cover for shipment and for application by the packer to the containers as if made in a single piece. x
Another object is to provide a sealing ring I having improved means whereby its ends mziy be attached, oneto the other.
11 describing the invention in'detail, reference is hereln had to the accompanying drawings, in which:
Figure 1 is a perspective view of the sealing ring; Y
Figure 2 is a view partly in side elevatiop and partly in section showing a can or 'pall equippedv with the invention and illustrating the application of the latter. Figure 3 is an enlarged detail View in side elevation of the two ends of a preferred form of sealing ring as they appear prior to attachment of one end to the other;
Figure 4 is a similar view showing the two ends in attached relation;
Figures 5 and 6 are views similar to Figs.
-3 and 4, respectively, showing a modified 1928. Serial in. 286,622.
3 and 4, respectively showing a third modified form of end attacl. ng means.
Referrlng to said drawlngs, 1 designates a can or pail having at its upper end an outwardly turned bead or roll 2. Seated in overlying relation to said roll is an outwardly directed rim 3, approximately semi-circular in cross section, formed circumferentially on a cover or closure 4 for the container.
Mounted in closely seated embracing relation to the rim 3 of said cover is the body portion of a ring 5, arcuate in cross section, formed of a single length or strip of sheet metal and which has a plurality of integral relatively spaced lugs 6 depending from its lower edge.
Said ring is designed to be pressed or sprung upon the rim 3 of the cover, in such manner that it is self retained with respect to the cover, prior to application of the cover to the container, or prior to shipment to the packer by whom the covers are applied. The cover and the ring are applied, asif made in one piece, by the acker for closing the conapplied parts in place.
The ends of the sealing ring, as shown in Figs l to 6, 8 and 9 are designed to be disposed in overlapping attached relation. As shown in Figs. 1 to 4, the overlapping end is provided with a suitably located transverse slot 7 which is adapted to have projected outwardly therethrough a tongue 8 which is struck up from the metal of the overlapped end of the rin and which extends longitudinally of and parallel to the ring and in a direction awayfrom said end. A shallow inwardly depressed seat 9'substantiall correspon'ding 1n size and form with sai tongue is provided in said overlapping end of the ring for the reception of said tongue, whereby the latter is permitted to occupy substantially the plane of the peripheral surface of said ring.
In the modification shown in Figs. 5 and 6, thetongue 8 is formed by a turned back extension of the overlapped end of the ring.
Additionally, a second transverse slot 10 parallel to the slot 7 a is provided between the engage in slots 7 provided in the adjacent ends of an overlapping coupling member 11 of short length, each of said slots having associated therewith tongue seats 9 similar to the seats 9 of Figs. 3 and 4.
In the modification shown in Figs. 9 and 10, the overlapped end is provided with an H-slot verse tongues 12. The overlapping end has a semi-cylindrical head 13 joined to the body of the ring by a neck 14 of reduced width. Said head 13is designed to seat in the opening formed by outward bending of said tongues 12 and then to have said tongues turned back in overlying seated relation thereto, as shown in Fig. 10. A short longitudinal extension or tongue 15 integral with the head 13 is designed to overlie the ring rearward of the H-slot 7 as shown in Fig. 10.
Following attachment of the twoends of the ring 5.in,the manner shown in Fig. 4, the seat 9 and the therewith engaged tongue 8 are together subjected to the action of'a punch press in which a cancavo-convex button or knob 16 is pressed in said parts, thus to safeguard against chance relative disengagement of said ends. Similar buttons or knobs 16 fand 16 are pressed in interengaged members or parts, as shown in Figs. 8 and 9, respectively.
To remove the ring'shown in Figs. 1 to 4, the tongue 8 is pried outwardly by means of a suitable instrument to the extent that the overlapping end is released, whereupon said ring may readily be stripped from the container by pulling upon said end. Similarly, when the tongue 8 of Figs. 5 and 6, one or the other of the tongues 8 of Figs. 7 and 8, and the tongues 12 of Figs. 9 and 10, are bent outwardly, separation of the attached ends of the rings 5 may readily be effected to permit stripping of the latter from cover sealing position. Q.
What is claimed is 1. A sealing ring of the character described, comprising a single strip of sheet metal, one end of said ring havmg therein a transverse slot andan inwardly pressed seat extending from said slottoward the terminal edge of said end, and the other end of said ring having a struck-up tongue entered outwardly through said slot and engaged in said seat so as to lie substantially flush with the first named end of the ring.
2. A sealing mug of the character de- Said tongues are designedto 7 defining oppositely disposed transscribed, comprising a single strip of sheet metal, one end of said ring having therein a transverse slot and an inwardly pressed seat extending from said slot toward the terminal edge of said end, andthe other end of said ring having a struck-up tongue entered outwardly through said slot and resting upon said seat, said tongue and said seat each having therein an outwardly pressed'concavo-convex button and said buttons being disposed in interengaged relation.-
3. A sealing ring of the character described, comprising a strip of sheet metal having a longitudinally disposed tongue formed on one end thereof and received in and having its sides engaged by the end walls of an opening in its opposite end, the free end of the tongue facing inwardly of the ring, and the tongue being wholly disposed exteriorly of and seated throughout its length against the outer face of the portion of the ring underlying the tongue, and said tongueand the portion of the ring which underlies said tongue having therein outwardly pressed buttons occupying interengag'ed relation.
4. A sealing ring of the character described, comprising a strip of sheet metal having means whereby its ends are joined,
' said means including a tongue formed on one of the ends of said ring and an opening in the portion to which said end attaches, said tongue being projected through said opening and the free end of the tongue facing inwardly of the ring and the tongue being wholly disposed exteriorly of and seated throughout its length against the outer face of the portion of the ring underlying the tongue, and having its' sides engaged with the end walls of the opening, said tongue and said portion having formed therein concavoconvex buttons which are interengaged one with the other.
5. A sealing ring of the character described, comprising a strip of sheet metal, one end of said ring having therein a transverse slot and an inwardly pressed seat extending from said slot toward the terminal edge of said end, and the other end of said a ring having a struck-up tongue entered outwardly through said'slot and engaged in said seat, so as to lie substantially flush with the outer first named end of the ring, and means to hold the tongue in its seat and with its outer end flush in the seat.
