| 20140150203 | ERASING MEMBER AND ERASING TOOL USING THE SAME - Provided are an erasing member which is excellent in erasability for handwritings written by means of a pencil, a mechanical pencil and the like and which does not produce eraser dusts, and an erasing tool in which a part to be erased can be visually recognized in erasing. | 06-05-2014 |
| 015425000 | Including handling means | 9 |
| 20130239362 | Eraser Bracelet - A flexible eraser bracelet fabricated from an elastomeric compound, capable of erasing marks, such as pencil markings, ink markings, the like, or indicia from a surface. | 09-19-2013 |
| 20140130297 | Insert Assembly for an Applicator - An insert assembly for an applicator is built from two semi-cylindrical retention jaws connected by a living hinge. Each of the semi-cylindrical retention jaws has a plurality of stake pins, while the first semi-cylindrical retention jaw has a locator receptacle and the second semi-cylindrical retention jaw has a locator insert. An insert is placed between the two retention jaws, which then close to secure the insert between the retention jaws. The locator receptacle receives the locator insert from the second semi-cylindrical retention jaw, helping to align the two retention jaws. The plurality of stake pins impale the insert, holding it in place. In addition to being secured by the stake pins, the insert is supported by an interior ridge. The insert assembly can then be slid into a barrel sleeve, held in place by a press fit or by a removable mounting system, such as a lug mount. | 05-15-2014 |
| 20140331448 | WRITING INSTRUMENT WITH ERASING MEMBER - A writing instrument ( | 11-13-2014 |
| 20150033499 | ERASING IMPLEMENT AND WRITING IMPLEMENT PROVIDED WITH ERASING IMPLEMENT - Provided are an erasing implement and a writing implement equipped with the erasing implement, the erasing implement being capable of erasing writing regardless of the type of ink or lead of the writing implement, even writing with thermochromic ink or writing with pencil lead. The erasing implement is equipped with a first erasing member for erasing writing with thermochromic ink and a second erasing member for erasing writing of types other than thermochromic ink, and is configured by covering the outer surface of the second erasing member with the first erasing member. | 02-05-2015 |
