4 Claims. (01. 229-51) The present invention relates to fibre containers having metal cover members and has more particular reference to improved closures therefor in which are embodied certain elements to effect easy opening of the containers.

An important object of the invention is the provision of a retaining ring or wire for a fibre container which is sealed or closed with a cover member, the retaining ring being partially embedded into the body wall of the container and which, when removed to open the container, leaves the cover member free for removal and for subsequent frictional engagement as a reclosure.

A further important object of the invention is 4 the provision of a container closure of the character described in which the retaining ring is pressed into the fibre body wall during the application of the cover member to efiect a closure and which unbends portions of the cover memher during the opening of the container so that the cover is freed from the ring as well as from the body and in such reshaped form is adapted for frictional engagement as a reclosure.

.Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawing:

Figure 1 is a perspective view of the container embodying the present invention;

Fig. 2 is a fragmentary front elevation, partly broken away, of the upper part of the container illustrated in Fig. 1;

Fig. 3 is an enlarged fragmentary sectional view taken substantially along the line 33 in Fig. 1, and illustrating the sealed container parts; and

Fig. 4 is a view similar to Fig. 3 illustrating a step in the removal of the retaining ring and in the opening of the container.

The present invention is particularly directed to an improved closure for a fibre container having a metal cover member and a retaining ring which has a dual function of assisting in forming a closure for the container and in reshaping certain parts 'of the closing elements in the opening of the container to permit its initial opening and'twpermit subsequent reclosing thereof.

For the purpose of illustrating the invention the drawing discloses a fibre container body having a bottom end l2 secured thereto in any suitable manner as by a crimped or other kind 55 of seam. The upper end of the fibre body (Figs. 3 and4) is practically straight without any projecting parts.

A metal cover member I4 is provided, having a cylindrical vertical wall i5 adapted to frictionally engage within the top or open end of the body II. This inner wall |5 is bent outwardly at its top into an annular curled rim l6 which is semi-circular in cross section. This rim merges into a downwardly extending wall I! substantially parallel to the wall l5 which terminates in a flange l8.

A retaining ring or wire 2|, preferably of circular cross section, is used as one element in the container closure and at the same time provides an opening device for breaking the closure seal when the container is opened. This ring encircles the can body adjacent its top and is adapted to be partially enclosed within the flange I8 of the cover member l4 when the latter is positioned on the body and the parts are brought into the .closed position illustrated in Figs. 1, 2 and 3.

Such closing of the container is effected in any suitable manner by means of which the cover flange I1 is crimped or otherwise forced inwardly against the ring 2| so that the latter is pressed into the wall of the fibre body I, making its own seat 22. ,This forms a curled flanged section 23 I and seals the container.

ring in an inclined section 25. This handlepart projects below the opposite end 28 of the ring (Fig. 2) and extends entirely free of the enclosed sealing flange parts 23.

When the container is to be opened the handle part 24 of the retaining ring 2| is forced downwardly to the position indicated by dotted lines in Fig. 2, the rest of the wire ring moving downward and away from the cover flange. In this movement the edge 23 of the cover flange is bent outwardly (as shown in Fig. 4) as the ring 2| rides out of its seat 22 and presses against the flange edge. This edge springs back a short distance as shown in this figure but is clear of the ring and clear also of the body wall.

The cover member I4 is now free to be lifted off of the container body After the container has thus been opened the cover may again be reseated as a reclosure, the walls I5, ll of the cover giving sufficient fit on the body to form a removable closure. The retaining ring 2| is discarded as no longer necessary.

His thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various-changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material ad vantages, theform hereinbefore described being merely a preferred embodiment thereof.

I claim: v

1. A container, comprising a tubular fibre body having a straight uncurled upper edge, a metal retaining ring adapted to be positioned on said body below its said upper edge and embedded by its own pressure into the otherwise straight wall of the body, and a metal cover 'member having an'inner supporting wall extending downwardly withinsaid container sufliciently to withstand the pressure exerted by said ring against the'container body, said cover member having an outwardly and downwardly extending flange enclosing said body edge and partially enclosing said retaining ring and being clamped against said ring sufliciently tight to cause the ring to form a seat within the body wall whereby to eflect a closure for said container, said retaining ring being also adapted upon removal from its embedded and enclosed position within the body wall ,to-be forced outward by the lower part of said seat and outwardly bend said metal cover flange to free said ring and permit unre-v stricted removal of said cover member from said body.

2. A container, comprising a tubular fibre body of uniform cylindrical contour having a straight. uncurled upper edge, a metal retaining ring adapted to be positioned on said body below its said upper edge, and a metal cover member having-a supporting wall within the end of said body extending down to opposite said ring, said cover member haying an outwardly and downwardly extending flange enclosing said body edge aria. partially enclosing said retaining ringand being clamped against said ring sufilciently tight to press the latter into said body wall against the resistance afforded by said supportirig wall, whereby to efiect a closure for said body.

tween the same and the cover member.

3. A container, comprising a tubular fibre body of uniform cylindrical contour having a straight uncurled upper edge, a metal retaining ring adapted to be positioned on said body below itssaid upper edge, and a metal cover member having a supporting wall within the end of said body extending down to opposite said ring, said cover member having an outwardly and downwardly extending flange enclosing said body edge and partially enclosing said. retaining ring and being clamped against said ring sufiiciently tight to press the latter into said body wall against the resistance afiorded by said supporting wall to prevent relative movement therebetween, said retaining ring being also adapted upon removal from its embedded and enclosed position to outwardly bend said metal cover flange to free said ring and permit unrestricted removal of said cover member from said body.

4. A container, comprising a tubular fibre body of uniform cylindrical contour having a straight uncurled upper edge, a metal'retaining ring adapted to be clamped into position on said body below its upper edge toform ,a depressed seat 'in said body wall, and having a projecting handle located beneath an end thereof, and a against the resistance afforded by said supp rting wall, said depressed seat cooperating with the cover flange to prevent relative'movement betwee'nthe body and cover, said retaining ring being also adapted upon removal from its enclosed position within the body wallseat by pressure on its said projecting handle to outwardly bend said metal coverfiange to permit unrestricted removal of said cover member from said body and adapt the former as a reclosure for said WILLIAM E. TAYLOR.
