摘要： Provided is a plastic eraser excellent in safety and environmental pollution resistance and, not detracting from the erasability thereof, further excellent in bleeding resistance and eraser dust gatherability. The eraser comprises a base resin such as a vinyl chloride resin and, as incorporated therein as a plasticizer, a liquid acrylic polymer having a glass transition point (Tg) of not higher than 0°C. The eraser may comprise the liquid acrylic polymer alone or as combined with one or more other plasticizers. Containing the liquid acrylic polymer as a plasticizer, the eraser has excellent bleeding resistance and excellent dust gatherability which could hardly be balanced.

摘要： An eraser dispenser is provided which can store in a dispenser body (1) an eraser longer than the overall length of the dispenser body (1). The eraser dispenser enables the eraser to be used without replacement with a new one for a long period of time. The eraser dispenser includes: a dispenser body (1) which is enclosed by an outer circumferential wall (2) having a distal opening (4) and has a storing chamber (8) capable of storing therein an eraser that is longer than the overall length of the dispenser body (1); and a cover (3) which covers the dispenser body (1). The eraser dispenser further includes; an external operation member (11) which partially projects from the outer circumferential wall (2) and is operated from the outside of the dispenser body (1); a driving roller (13) which is operated by the external operating member (11); a receiving member which is disposed opposite to the driving (13) roller with the eraser held therebetween; and a stopper which prevents a rotary button (11) as the external operation member (11) from undergoing reverse turn.

摘要： Provided are a writing instrument produced at a lower cost than conventional thermochromic writing instruments utilizing frictional heat, slim like a pencil and not bulky because it contains an ink directly in a barrel thereof, and excellent in portability; and a set of the writing instruments.
The writing instrument 1 is obtained by directly filling a barrel thereof with an ink 2 which becomes colorless or colored, or undergoes a color change by heating and an ink follower 5 following the ink with its consumption; firmly fixing a writing tip portion 3 to the end of the barrel directly or via a relay member; and disposing a friction body 6 having an elasticity at the rear end portion of the barrel. The writing instrument set has a plurality of the writing instruments respectively different from each other in color tone.
