A bound document is made by placing one or more sheets of paper to be bound inside a binder having a hot-melt adhesive and then exposing the binder to microwave energy for a sufficient period of time to cause the hot-melt adhesive to melt bond onto an edge of the sheets of paper. In one embodiment of the invention, the hot-melt adhesive is microwave activatable. In another embodiment of the invention, the hot-melt adhesive is not necessarily microwave activatable and the binder includes a strip of susceptor material which converts incident microwave radiation to heat. In still another embodiment of the invention, the hot-melt adhesive is not necessarily microwave activatable and a quantity of microwave responsive material is incorporated into the hot-melt adhesive. In still yet another embodiment, the hot-melt adhesive is not necessarily microwave activatable, and a microwave susceptor is incorporated into a stand on which the binder may be placed during exposure to the microwave radiation.

Method and appartus for the pouring of liquids by a partially closed shell extending from a base to a rounded and interrupted tip, with partially opened shell sides extending from the base to the tip which is interrupted by a a "V" shaped notch; the shell has a base advantageously inclined with respect to the pouring axis of the shell to permit downward flow of fluid into an aperture that communicates with the opening in the shell; the shell can be a pouring spout covered by a protective cap which is unscrewed and removed to expose the spout and permit fluid to be poured between open sides along the shell and over a sharp, interrupted edge at a tip, by which flow is terminated when the shell is up-righted, so that the sharpness of the interruption and the general configuration of the tip reduce the usual dripping of fluid after a pour.

A picture frame for photographic snapshots having a rotatable easel of thin, lightweight construction mounted to the back side of the picture frame. The easel has a substantially trapezoidal shape when folded and has rectangular front and back panels having a common top edge and collapsible, triangular side panels interconnecting the front and back panels. The side panels may be folded, collapsing the easel into a flat structure for easy packaging and shipment. The side panels when unfolded form an easel for holding the picture frame in a stable, secure, upright position on a tabletop. The easel design of the invention produces an unusually stable structure for its weight. It does not collapse upon moving the picture frame in any direction on the table surface. The easel may be rotated to permit display of snapshots in either a horizontal or vertical orientation.

A dispenser for correction tape, reinforcement tabs and the like which is singularly capable of housing and dispensing one at a time of a permanent correction tape or permanent reinforcement tabs each of which includes a releasable backing sheet. The dispenser is also capable of housing and dispensing a readhering correction tape which does not require a separate backing sheet. The dispenser is of integral plastic construction molded as a single unit preferably by injection molding. The dispenser is adapted for easy loading and dispensing of the permanent correction tape, the permanent reinforcement tabs, or the readhering type correction tape. The dispenser is composed of a case which has a backface, two opposite facing side walls, a bottom panel, and an open front area. A cylindrical spindle is connected to the backface and protrudes into the case. The spindle holds the tape.

A dry wipe marking board which is wall mountable and convertible to display a picture or painting while concealing the writing panel. The convertible dry wipe board is composed of a wall mountable support panel to which is secured a foldable dry wipe writing panel. When not in use the board may be folded along a hinge line to completely conceal the writing panel and display in its place a picture or painting which has been secured to the backside of the support structure. The conversion can be accomplished without removing the dry wipe board from its hanging position on a wall surface and without removing any component from the hanging structure. The dry wipe writing panel itself is preferably composed of a white pigmented polypropylene panel which is used for marking or writing thereon with conventional dry wipe marking instruments.

Cover folders having binders that securely retain the cover and inserted sheets, without the use of external fasteners. The binder is an elongated bar with an interior channel for receiving and holding a folded cover. The bar includes within the channel slanted ribs which engage the folded edge of the cover sheet along an overlapping flap. The overlapping flap of the cover sheet may be made more rigid by heat treatment and/or by a reinforcing coating.
