Patented June 19, 1945 Allen B. Wilson, Evanston, Ill., assignor to Acme Ill Stgl I:lonipany, Chicago, III., a corporation of Application May 5, 1941, Serial No. 391,829 10 Claims. ('01. 9339.l)

This invention relates to improvements in containers and method oi forming them and its purpose is to provide a vessel, formed largely of paperboard or the like, which may be used for packing and shipping products of a granular or plastic nature, such as cereals, chemicals, sugar or the like.

The principal object of the invention is to provide a container having an annular nonmetallic wall which is capable of being packed andshipperf'in flat condition in a bundle with other similar wall portions and of being readily assembled by the user in proper relation to end walls and annular metallic rims, which may also be packed and shipped separately. Another object of the invention is to provide a container comprising an annular wall and end walls each formed of separate parts which may be secured together for holding in assembled relationship the end walls and the annular wall and also metallic rims which extend around the end portions of the annular wall. A further object is to provide an improved method of forming and assembling a container according to which a flat sheet 01' paperboard or the like is provided along its longitudinal edges with projecting tabs adapted to be extended inwardly to form upper and lower flanges when the sheet is rolled into annular form and its edges united, the flange at each end of the wall being then turned inwardly between the inner and outer end wall sections which also enclose an annular flange of a metallic rim arranged to surround the end portion of the annular wall, these end wall sections being then stitched together through the tabs to hold all of the parts in assembled relationship.

Other objects relate to various features of construction and arrangement and to various details of the method which will appear more fully hereinafter.

The nature of the invention will be understood from the following specification taken with the accompanying drawing in which one embodiment is illustrated. In the drawing,

Figure 1 shows a side elevation of the improved container when it has been completely assembled;

Fig. 2 shows a partial axial vertical section and partial perspective view of the container illustrated in Fig. 1;

Fig. 3 shows a top plan view of the container illustrated in Figs. 1 and 2 with parts thereof broken away; and

Fig. 4 shows, on a reduced scale, a plan view of the annular wall in the flat condition in which a it is shipped to the user.

As illustrated in the drawing, the invention is shown as being embodied in a container comprising a cylindrical upright wall in formed of a sheet of paperboard or the like with its overlapping edges sccured together by wire stitching II.- The ends of the annular wall are surrounded by a a lower metallic rim l2 and an upper metallic rim l3, which rims are interlocked with the bottom wall M and the top wall l5, respectively. The bottom wall I4 is of circular form and is made up oi two disks I I? and N formed of relatively stilt paperboard or the like, which are secured together by wire stitching I8. Similarly, the top wall I5 is formed oi two disks I! and ii", formed of relatively stifi paperboard or the like, which are secured together by wire stitching II. To permit access to the interior of the container after its parts have been completely assembled, the top wall I5 is provided with a removable cover I8 comprising a circular disk I 8 which occupies and closely fits a circular hole l5 formed in the lower disk l5 of the top wall, and anupper disk I8 which is of larger diameter than the disk l8 so that it overlaps the edge of the hole li The disk lab-is glued or stitched to the lower disk lll and it is provided with a plurality of outwardly extending wings 18 which are adapted to underlie a series of inwardly extending wings li which are formed in the top section I5 of the top wall between the outwardly extending notches lit in this wall. The aperture I 5 in the wall section I 5' which lies within the inner margins of the wings or tongues I5 is slightly larger in diameter than the disk- I8 so that, when the removable cover I8 is rotated to a positionwhere the wings la register with the notches li the cover may be lifted upwardly through the aperture l5 in the top wall and entirely removed to permit access through the hole l5 to the interior of the container. Upon replacing the cover l8, it may be rotated, after inserting the wings l18 through the notches I 5', so that these wings will then underlie the projections li as shown in Fig. 2, thereby securing the cover in its closed position.

The annular wall III of the container is formed from a flat sheet III of paperboard or the like. which is substantially rectangular in form-,as shown in Fig. 4, and which is provided along its longitudinal edges with a plurality oi projecting tabs Ill". These tabs are of tapered formand are provided with outer edges l0 which are in alignment with each other on eachside of the sheet and parallel to the longitudinal :axis of the sheet. The metal rims l2 and I3 are-identical in form and are formed preferably from straight metal strips which are subjected to a rolling and curlingprocesstocausethemtoassumethe shape illustrated. After being curled into annular form, the overlapping ends of each rim are secured togetherby spot welds or the like, as

shown at ll, thus providing complete annular rims which are shipped in this form. from the placeor manufacture to the place of use.

i The bottom rim l2 comprises a, cylindrical portion I! which is adapted to flt over the lower end of the wall II and which is flared outwardly along its upper edge as shown at i2 to permit it to be passed readily over the cylindrical wall in the process oi assembly. The lower edge of the cylindrical part I! is united with an inwardly extending annular part I2, located in a plane extending parallel to the bottom wall I4, and this part l2 is united with an upwardly extending annular part II forming an annular shoulder within which the lower-disk of the bottom wall is located. The annular part I! is united along its upper edge with an inwardly extending annular flange i2 which projects between the bottom disk ll" of the bottom wall and the inwardly extending flange I8 formed by the tabs Ill along the lower edge of the wall II. The top rim i8 is similar in form to the rim l2, although it is reversed in position. This rim comprises a cylindrical body portion ii an outwardly flared edge I3", and parts IF, it and II which correspond in form and relative location to the parts I29, I! and 12, respectively.

The end wall sections ll, ll I5 and I5", and theparts oithe cover is may be stamped from sheets of still cardboard and shipped to the user in compact bundles.

'In the operation of assembling the parts of the container, the sheet I0 is flrst rolled into cylindrical form and the overlapping edges are united by the wire stitching I I. The tabs Ill of one end of the cylinder are then bent inwardly over the disk l5, which is preferably seated upon a suitable upright pedestal or support. The top rim i3 is then placed in position over the upper end of the annular wall In with the flange |3 resting upon and holding in position the tabs lo of the annular wall which form the upper inwardly extending flange Hi The next step is to place the top disk li oi the top wall in P sition over the flange l3" of the top rim. The stitching I1 is then applied to secure the two disks I5 and l5 together, thereby clamping the flange l3 between the top disk andthe flange w of the outer wall so that the rim is held in fixed relation to the annular wall as well as with respect to the top wall IS. The stitching Il may extend through the tabs iii which form the top flange Ill of the annular wall III, as shown in the drawing, but this is not essential.

' Having secured the top wall l5 and the top rim B to the annular wall, in the manner described above, the partially assembled vessel is removed from the supporting pedestal and reversed in position, with the pedestal extending upwardly through the apertures I5 and l5 in the top wall, and the disk I4 is then inserted within the wall In until it rests upon the pedestal or support with its outer edge located just below the bases of the tabs I0" which are to form the lower flange Ill oi the annular wall. These tabs Ill are then bent inwardly over the disk i4 preliminary to putting in place the lower rim l2 with its cylindrical part l2 surrounding the end portion of the wall l0 and with the flange l2 holding the tabs i0? against the disk I4, The disk l4 is then applied within the flange I2 and against the flange II, whereupon the two disks I4 and N are united by the stitching I8. This stitching may also extend through the tabs ll" which form the lime ll and the flange I2 is thereby secured in position between the flange ll and the bottom disk ll oi the bottom wall. The parts oi! the container are then completely assembled except for the insertion of the cover is which may beput in position after the container has been removed from the supporting pedestal, reversed in position, and fllled with its contents. In this way, there is provided a strong and durable container which may be readily assembled by the user without the use of any tools or other auxiliary devices, except the stitching device required for uniting the disks of the end walls by the wire stitches It and II. The rims I2 and I3 may preferably have a loose flt upon the wall Ill to facilitate the assembly of the container and also to prevent damage to the paperboard of which the annular wall i0 is formed Although one form of the invention has been shown and described by way of illustration, it will be understood that it may be constructed in various other embodiments coming within the scope of the appended claims.
