Abstract
A cap for a pencil, comprising an insertion opening, at least two internal retainer ribs which are distributed angularly and uniformly about a central axis of the cap. The at least two internal retainer ribs positioned close to the insertion opening and configured to cooperate with an unsharpened portion of the pencil, and a stop surface which is configured to cooperate with a sharpened end of the pencil.

A cap for a pencil comprising an insertion opening that is designed for receiving an end of the pencil, at least two internal holding ribs that are distributed angularly in a uniform manner about a central axis of the cap, the at least two internal holding ribs being arranged in the vicinity of the insertion opening and being designed for cooperating with a non-sharpened portion of the pencil, an arresting surface that is designed to cooperate with a sharpened end of the pencil, and a stop that is designed to cooperate with a non-sharpened end of the pencil, wherein the stop and the arresting surface are borne by an arresting rib, and wherein the arresting surface is configured to cooperate with the sharpened part of the pencil such that the lead of the pencil cannot be pushed into a base of the cap.
A pencil cap comprising:
- an opening for receiving an end of a pencil, a pair of ribs positioned angularly and uniformly about a central axis of the pencil cap, the pair of ribs being positioned adjacent to the opening and configured to cooperate with a non-sharp portion of the pencil, a surface configured to cooperate with a sharp end of the pencil, and a stop configured to cooperate with the non-sharp end of the pencil, wherein the stop and the surface are borne by an arresting rib, wherein each rib of the pair of ribs comprises a clamp configured to cooperate with the non-sharp portion of the pencil, the clamp having a fixed, inscribed diameter positioned in a plane perpendicular to an axial direction, and wherein the fixed, inscribed diameter is equal to or greater than about 95% of a minimum inscribed diameter of the pencil and less than or equal to about 99% of the minimum inscribed diameter of the pencil.
A cap for a pencil comprising a cap body and an opening sized to receive an end of the pencil, three internal ribs, uniformly distributed about a central axis of the cap, the three internal ribs located proximate to the opening and cooperating with a non-sharpened portion of the pencil, an arresting surface that is fixed with respect to the cap body, the arresting surface cooperating with a sharpened end of the pencil, and a stop cooperating with a non-sharpened end of the pencil, wherein the stop and the arresting surface are borne by at least a third rib of the three internal ribs, wherein the cap has a hexagonal shape in a perpendicular plane relative to the central axis.
