    Abstract: A crayon protector comprises a covering which is substantially cylindrical in configuration. The covering is made of unbreakable, non-cuttable, yet flexible material, for instance molded plastic. The covering is configured with open ends and a longitudinal slit which prevents complete encircling of the crayon. The covering is inserted on a crayon and substantially surrounds and reinforces it from breakage at its break zone. The slit facilitates insertion and removal and allows flexible expansion of the covering for use with crayons of varying diameters. The protector can also be used to prevent breakage of other relatively easily breakable writing implements, like chalk, pastel and charcoal sticks.

    Abstract translation: 蜡笔保护器包括基本上圆柱形的覆盖物。 覆盖物由不可破坏的,不可剪切的,但是柔性的材料制成,例如模制塑料。 覆盖物构造有开口端和纵向狭缝,防止蜡笔完全环绕。 将覆盖物插入蜡笔上,并基本上围绕并加强其在其断裂区域的断裂。 狭缝有利于插入和移除,并允许覆盖物的柔性膨胀用于不同直径的蜡笔。 保护器也可用于防止其他相对容易破损的书写工具(如粉笔,粉笔和木棍)的破损。
