## Abstract

A container for a stack of newspapers includes bottom, side, and back walls and a substantially open front to facilitate stacking newspapers in the container, and inspecting the stack for non-paper contaminants. A pair of rotatable wheels on the bottom of the container, and a base on the bottom of the container are adapted to rest on a horizontal supporting surface such as a floor. A pair of inwardly extending lips on the front of the container restrain the stack of papers when the container is tilted and rolled from one location to another. The container bottom slopes downwardly away from the open front of the container, and the back of the container slopes upwardly away from the open front to promote forming a stack which is slightly inclined to vertical when the container rests on the horizontal surface. External means on the container facilitate picking up the container and dumping the stack of papers in a collection truck.

## Claims

### Claim 1

A container for storing a stack of substantially horizontal sheets on a substantially horizontal support, the container comprising a base being adapted to rest on the substantially horizontal support, a pair of upright sidewalls spaced from each other and secured to, a bottom wall, wherein the bottom wall is located adjacent to the base, an upwardly extending back wall disposed between the sidewalls, the front of the container being substantially open to facilitate loading sheets in the container with the sheets being generally horizontal to form a stack of sheets in the container, and to facilitate inspection of the stack for any contaminants in it, a separate inwardly extending retainer at the front edge of each side wall, the retainers extending toward each other so the horizontal distance between them is substantially uniform, each retainer having a horizontal dimension from front to back substantially less than that of the sidewalls, wheels mounted at bases of the container to rotate about a substantially horizontal axis adjacent the front of the container so the container can be tilted out of contact with the support and rolled on the wheels to transport the stack of sheets in the container, and a handle secured to an upper part of the front of the container to facilitate tilting the loaded container.

### Claim 2 (depends on 1)

A container according to claim 1 in which the horizontal distance between the retainers is at least about 8″.

### Claim 3 (depends on 1, 2)

A container according to claim 1 or 2 in which the handle extends forward of the container to facilitate dumping the stack when the container is inverted.

### Claim 4 (depends on 1, 2)

A container according to claim 1 or 2 in which the back wall extends upwardly and away from the front of the container to form an inclined support for the stack when the base of the container sets on the horizontal support.

### Claim 5 (depends on 1, 2)

A container according to claim 1 or 2 in which the bottom wall slopes downwardly from the front to the back of the container when the base of the container rests on the horizontal support.

### Claim 6 (depends on 1, 2)

The container according to claim 1 or 2 in which the back wall extends upwardly and away from the front of the container to form an inclined support for the stack when the base of the container rests on the horizontal support, and the bottom wall slopes downwardly from the front to the back of the container when the base of the container rests on the horizontal support.

### Claim 7 (depends on 1, 2)

A container according to claim 1 or 2 which includes a forwardly extending step plate at the front of the lower portion of the container to facilitate tilting the container to rest only on the wheels.

### Claim 8 (depends on 1, 2)

A container according to claim 1 or 2 which includes lifting means on the exterior of the container to facilitate automatic pick-up, inverting an dumping the container.
