Abstract: A dispenser for applying a material to a surface includes a supply spool rotatable about an axis, a quantity of unused tape stored on the supply spool, and an applicator head about which the tape is passed. The head presses the tape against a surface to deposit a transfer layer of the tape onto the surface. A take-up spool stores a backing layer of the tape after the transfer layer has been deposited on the surface. The take-up spool is also rotatable about the axis. A housing surrounds at least a majority of the tape, a substantial portion of the housing being substantially cylindrical in shape. The tape is guided from the supply spool to the head and from the head to the take-up spool. The applicator head is located substantially along the axis, and the spools are movable along the axis. The tape causes movement of the spools along the axis as the spools are rotated about the axis. The-tape is stored on each spool in a plurality of tape layers thick and a plurality of tape widths wide.

Abstract: A dry-wipeable overhead projector film ink is provided which includes a colorant, an acrylic polymer having a film forming temperature below room temperature, and water. Preferred inks further include a surfactant and an anti-drying agent. The inks are easily removable from most types of overhead projector film by wiping with a dry cloth or fingertip. Certain preferred inks are also removable by wiping with a wet cloth.
Abstract: A hand-held fluid delivery system includes a rigid body, a collapsible enclosure within the body, a fluid (e.g., correction fluid) within the enclosure, and a delivery end in communication with the collapsible enclosure. The delivery system preferably includes a spring that applies pressure to deliver fluid from the collapsible enclosure to the delivery end.

Abstract: A writing implement has a grip for providing improved comfort and stability to the user. The writing implement includes a barrel having a front end and a writing member partially disposed in the barrel, the writing member having a tip extending outside the front end of the barrel. A resilient gripping portion is attached to the barrel and defines an outer surface. A column of grooves are formed in the gripping portion outer surface. The grooves are aligned longitudinally to form interposed ribs shaped to resist slippage away from the tip.
Abstract: Writing instruments include a foam layer covering the outer surface of a preformed tubular core. The writing instruments are formed by a pultrusion process.

Abstract: Caps are provided for covering the writing end of a writing instrument containing a non-solid writing material. The caps include a cap body having an open end for receiving the writing end and a closed end for covering the writing end and having a long axis extending from the open end to the closed end, and a sealing member disposed within the cap body, a portion of which is fixed axially relative to the long axis of the cap body. In some caps, the cap body defines an air flow passage extending from the open end to the closed end.
Abstract: Pressure generating gas-releasing compositions which are microcmulsions, siloxane or hydrocarbon greases or elastomers, are used to aid dispensation of a fluid from a reservoir without the composition itself being dispensed. Dispensers containing such compositions can include writing implements.
