  • Patent number: 11206911
    Abstract: A pencil (e.g., cosmetic pencil or otherwise) with a disposable cap including a built-in sharpener which is configured to permanently capture and store shavings produced as the pencil is sharpened. The cap with permanent shavings storage prevents accidental (or even intentional) emptying or other exit of generated shavings from the permanent storage cavity in the disposable cap, which shavings may smear or otherwise damage a user's purse, pocket, clothing, or the like. The device is configured to collect such shavings during the useful life of a single pencil body, after which period any remaining short stubby portion of the pencil body, and the associated disposable cap with built in sharpener (and permanent shavings storage) is discarded.

  • Patent number: 9227460
    Abstract: A reciprocating pencil sharpener has a stationary member, a cutter and a ratchet mechanism. The cutter includes a blade secured to a blade holder. The ratchet mechanism is mounted between the stationary member and the cutter and allows the cutter to rotate relative to the stationary member in one direction only. When a user desires to sharpen a pencil, the user can keep the pencil in the hand and rotate the pencil in reciprocating rotation, thus obtaining the sharpened point of the pencil. Consequently, it is convenient for the user to apply a rotational force and a high efficiency of sharpening operation is achieved.

  • Patent number: 8881410
    Abstract: A sharpener for sharpening a pencil, in particular a cosmetic pencil, is especially suitable, when used correctly, for producing a particularly uniform outer jacket edge in the region of the pencil tip. The sharpener includes a sharpener body, in which a pencil guide channel is provided. The pencil guide channel has a circular cone-shaped channel section and opens out in a pencil inlet opening on the outer side of the sharpener body. A paring blade is positioned tangentially to the lateral surface of the channel section. The paring blade serves to pare off a pencil tip, which includes a front lead section and a rear outer jacket section. A shaping tool cuts a shoulder into the pencil tip, the shoulder being set back in relation to a circular cone-shaped enveloping surface of the pencil tip. The shaping tool is arranged relative to the pencil guide channel to insert the shoulder into the transition between the lead section and the outer jacket section of the pencil tip.

  • Patent number: 8505596
    Abstract: A cutter assembly for an electric pencil sharpener has a cutter bracket and a cutter. The cutter bracket has a pencil sharpening hole and an engaging structure. The pencil sharpening hole is defined in the cutter bracket for a pencil to be inserted into the pencil sharpening hole. The engaging structure is formed on the cutter bracket to engage a rotating frame in the electric pencil sharpener. The cutter is mounted rotatably on the cutter bracket. Accordingly, the cutter assembly is replaceable for the electric pencil sharpener when the cutter of the cutter assembly is damaged or worn.

  • Patent number: 8459317
    Abstract: Disclosed is a hand-crank pencil sharpener, comprising a housing and a gearing member and a sharpening member which are installed within the housing. The gearing member is connected to a hand crank and transmits a rotation of the crank to the sharpening member. A vertical feeding path is provided for a pencil to be inserted into the sharpening member. The hand-crank pencil sharpener further comprises a feeding member in the feeding path. The gearing member comprises a gearing branch for driving the feeding member. The inserted pencil is fed into or withdrawn from the sharpener automatically by a linkage of the gearing branch and the feeding member when the crank is rotated clockwise or counterclockwise.

  • Publication number: 20080244917
    Abstract: A sharpener, particularly a cosmetic pencil sharpener, contains a sleeve-like sharpener housing whose inside diameter for rotationally guiding the pencil to be sharpened is dimensioned so that it is somewhat larger than the outside diameter and whose inside length is dimensioned in such a manner that it enables a pencil end section to be conically sharpened by a sharpening blade diagonally projecting into the inside cross-section of the sharpener housing. Another sleeve-like housing section is situated at the end of the sharpener housing opposite the insertion end and is separated from the sharpener housing by a partition The inner area of the second housing section is provided in the form of a tight blind bore with an inside diameter approximately corresponding to the outside diameter of the pencil to be sharpened and, in the form of a pencil protector, and can be slid onto the pencil with a press fit.

  • Patent number: 7389588
    Abstract: The present invention relates to a semi-automatic pencil sharpener comprising a sharpening body and a blade; the sharpening body has a conical bore with a throughslot for allowing shavings to go out; and the blade is disposed outside the sharpening body on one side of the shavings throughslot; an external housing is disposed outside the sharpening body; the external housing comprises a pencil fixation casing and a rotation casing which can rotate opposite to each other; the pencil fixation casing and the rotation casing are removably engaged with each other. The present pencil sharpener can be operated with one hand. It is convenient to use in comparison with available products and has a high degree of automation. Pencil shavings produced from pencil sharpening using the present invention can be stored in the pencil sharpener without falling out affecting hygiene. The present invention is therefore relatively easy to clean up and is environmental friendly.

  • Patent number: 6886614
    Abstract: A pencil sharpener having a sharpening sub-assembly for sharpening pencils, and first and second external shells having internal ribs defining surfaces for supporting the sharpening sub-assembly. Components of the sub-assembly are placed into corresponding portions defined by the internal ribs. The ribs ensure proper alignment of the components relative to the shell and each other, e.g. in the x- and y-directions. All components may be placed in the shell in a single direction, e.g. in a single axial direction (the z-direction). The components of the pencil sharpener are mounted in place upon fastening together of the first and second external shells. No internal or additional fasteners are required. The sharpening sub-assembly may include an electric motor, a gear assembly, and a cutter assembly including a cutter gear module having an annular ring gear, acting as a carrier support, and housing a pencil insertion switch and/or a receptacle presence switch.

  • Patent number: 6725549
    Abstract: A sharpener for a carpenter's pencil that creates a profile shape desired by carpenters rather than a conical point. One end of the sharpener creates a sharpened profile on the narrow side of the pencil, while the opposite end of the sharpener creates a sharpened profile on the wide side when the pencil is rotated 90° about its axis. The pencil is slid laterally back and forth in a guide member, advancing along its axis as material is removed from the narrow side by fixed blades shaving material at an angle. The pencil is then rotated 90° and inserted in the other guide and moved back and forth advancing along its axis as material is removed from the wide side by fixed blades in a similar manner.
