CONTAINER Filed' April 8, 1956 Patented Aug. it), 1937 UNITED STATES PATENT OFFICE Application Aprilr8, 1936, Serial No. 73,277

2 Claims.

This invention is directed to the means provided for binding and reinforcing the lower rim of a Substantially cylindrical container intended primarily, but not exclusively, for-the shipment of ice cream in bulk. Containers of this type are constructed of relatively stifl' paper-board, and are designed ordinarily for a'single service, and such a container requires the use of metal reinforcing strips for the upper and lower rims or margins in order to stiffen the container and hold it properly distended.

The present invention is directed to the form and construction of such lower binding strip and means for securing it firmly and tightly in place.

Further objects and details. will appear from a description of the invention in conjunction with the accompanying drawing, wherein- Figure 1 is a perspective view of a container embodying the features of the present invention.

Figure 2 is a fragmental vertical sectional view of the fibrous wall of the container.

Figure 3 is a perspective fragmental view of the fibrous wall of the container.

Figure 4 is a perspective view of the bottom disc.

Figure 5 is a fragmental vertical sectional view of the container showing the lower ring structure.

Figure 6 is a perspective fragmental detail view of the lower binding strip.

The container is formed to provide a substantially cylindrical wall Ill formed of paper-board which may be truly cylindrical or slightly tapered and of suficient thickness and stiffness to aflord 5 an enclosure for several gallons of ice cream, or the like. It will be understood, however, that although the present invention is especially adapted to reinforcement of relatively large containers, it can be applied with like advantage to con- 40 tainers of smaller size. I y

The container ar nd its upper rim or margin is provided with a m allic binding strip I, which is claimed in application Serial No. 5,926, Patent No. 2,048,211, July 21,1936. This strip is bent to af- 45 ford an outer lip, an inner lip, and a bend or fold which arches over the upper edge of the container wall.

The lower margin of the container is provided with a metallic binding strip 2 bent to aflord 50 an outer lip II, an inner lip I2, and a bend or fold I3 which'arches over the lower edge 3 of the container wall. 1

Theouter lip I I is provided with an outwardly extending bead I5 afiording a circumferential rib, 55 and is also provided above the bead at recurrent intervals with inwardly extending burred bosses I6 which are formed by punching the metal of the strip to afi'ord apertures, displacing the metal inwardly at an abrupt angle to provide the bosses mentioned, which surround the apertures 5 and are adapted to impinge into the surface of the wall. The inner'lip I2 may be provided with stiffening crimps or corrugations I4. The strip thus formed constitutes a binding. hoop 2 for the lower edge of the paper-board wall. 10

The inner lip I2 of the bindingstrip is bent at an angle to thewall of the container as shown in Figure 5, and its outer edge I! serves as a support for the circumferential portion of the circular bottom disc I8. The lower wall portion 15 of the cylindrical container is expanded into the circumferential groove I5 of the lower binding strip so as to conform to its contour, thereby forming a circumferential groove I So in the lower portion of the wall. A bottom disc I8 is provided 20 with the proper diameter so as to fit tightly into the circumferential groove as shown in Figure 5, when it is pushed into position through the top opening of the container.

In assembling the binding strip and'the cylin- 25 drical wall the lower binding strip is formed into a loop and then slipped over the lower edge of the paper-board wall. The outer lip I I and paperboard wall overlying same are then subjected to a rolling or crimping action between suitably 30 configured rolls which serve to press together the container wall and the outer lip of the hoop so as to cause the burred bosses I6 to pierce into the surface of the container wall and to expand the container wall I0 into a circumferential groove so as to form a corresponding groove lie in the fibrous wall. This assembly insures a tight, firm grip of the hoop upon the container wall. The hoop thus stifiens and reinforces the lower edge of the wall and serves to maintain the shape 40 of the lower rim. i

Although the invention is particularly adapted for use in the reinforcement of containers of the class described, the binding strips or hoops oi the present invention are well adapted for other uses in which it is desirable to provide a metal reinforcement for the edge of a fibrous sheet or wall, I so that it will be understood that it is not the intention, unless otherwise indicated in the claims; to strictly limit the invention to the particular use shown and described.

1. In a container, the combination of a curving wall of fibrous material, and a metallic hoop secured to the lower rim of the wall, the hoop comprising inner and outer lips and a connecting bend overlapping the lower edge of the wall, the outer lip being provided with a plurality of inwardly extending burred bosses impinging into the surface of the container wall and with an outwardly ex-' tending circumferential bead located below the bosses and having the wall of the container expanded therein for forming a circumferential groove for receiving the bottom disc, the inner lip being bent at an angle to the wall for contacting the bottom disc.

2. In combination with a fibrous wall of a conextended position, said bottom panel being supn ported by said extended inner lip.
