Abstract: A waste basket simulating a basketball net comprises a square container constructed from a blank of corrugated paperboard in such manner that it can be manually erected from a substantially flat, collapsed condition and vice versa. The waste basket includes a square cover which fits over the top of the container and has therein a circular opening matching the graphic representation of a basketball net on each of the four sides of the container.

Abstract: A self-exposing imaging element is disclosed comprising a support member, a light sensitive layer, and a layer containing reagents which will chemically react in a chemiluminescent reaction to produce light which exposes the light sensitive layer when in contact with an original. Reagents in the light generating layer are physically or chemically segregated prior to exposure to prevent reaction, for example, by encapsulation of one of the reactants, the reaction solvent, or a catalyst. To copy the self-exposing imaging element is placed in contact with an original, the light generating layer is activated by causing the reactants to mix or introducing the reaction solvent or catalyst and the radiant energy generated produces an image of the original in the radiation sensitive layer by reflex imaging or direct transmission imaging.

Abstract: A one-piece plastic closure mechanism is provided which incorporates two flexible living hinge sections so that the leaves of the closure mechanism can pivot through the angles required for locking and unlocking a container cover from a container base. The closure mechanism may be attached to the base by screws, staples, or the like or may be integrally molded with the container to eliminate any post-molding assembly steps. One leaf of the closure mechanism contains a slot which engages a protrusion such as a tab on the container cover to lock the cover and base when the mechanism is closed. The container is designed so that individual containers are nestable for shipment, storage, and display. The interior of the container cover is provided with a clip for holding a writing implement and with a series of vertically upstanding ridges so that documents can be viewed in an upright position when the container is open.
