Abstract
An enclosure forms the structure of a cosmetic pencil sharpener, featuring an entry point for pencil insertion and a sharpening mechanism that interacts with this entry. This sharpening mechanism consists of a pair of opposing planar cutting blades, each possessing straight cutting edges directed away from the entry. When put into action, these cutting blades separate upon pencil insertion, and they are designed to come together with a bias. This results in the cutting edges engaging the pencil's tip from opposite directions as the pencil is withdrawn.
Claims21
A cosmetic pencil sharpener comprising:
- an enclosure comprising a pencil insertion entrance and a sharpening mechanism operably interfacing the entrance, the sharpening mechanism comprising an opposing pair of planar cutting blades having straight cutting edges orientated away from the entrance and wherein, in use, the cutting blades move apart when the pencil is inserted therebetween and are biased together so that the cutting edges cut oppositely into a tip of the pencil as the pencil is retracted;
- and
- a centring mechanism which centres the cutting edges of the cutting blades at a midpoint with respect to the entrance.
A cosmetic pencil sharpener comprising:
- an enclosure comprising a pencil insertion entrance and a sharpening mechanism operably interfacing the entrance, the sharpening mechanism comprising an opposing pair of planar cutting blades having straight cutting edges orientated away from the entrance and wherein, in use, the cutting blades move apart when the pencil is inserted therebetween and are biased together so that the cutting edges cut oppositely into a tip of the pencil as the pencil is retracted;
- compression springs acting between the cutting blades and interior surfaces of the enclosure, wherein the compressions springs are configured to bias the blades together;
- spring engagements, wherein the spring engagement interface the blades and the compression springs;
- and
- blade mounts, wherein the cutting blades are coupled to distal ends of the blade mounts and wherein the blade mounts comprise the spring engagements on outer surfaces thereof.
