A pencil device includes a body and a disposable cap. The disposable cap is selectively positionable so as to cover the first end of the body. The disposable cap includes a proximal end body portion having an opening, an opposite distal body portion having a storage cavity, and a built-in sharpener fixed between the proximal end body portion and the opposite distal body portion. The storage cavity is sealed for permanent storage of the shavings, A biasing member can be coupled to a side wall of the proximal end body portion configured to switch the disposable cap between a capping position and a sharpening position. Additional pressure is required to push the disposable cap from the capping position to the sharpening position. Upon release of the additional pressure, the disposable cap automatically returns to the capping position from the sharpening position.

A feeding pencil includes a main body including a main body barrel having a tubular shape, a front barrel detachably engaged with the main body barrel, and a cartridge disposed in the front barrel to receive a drawing material. The cartridge includes a tubular portion provided on a rear side of the cartridge, the main body includes an insertion portion provided on a front side of the main body and configured to be engaged with the tubular portion. When the cartridge is tilted from the main body, an engagement between the tubular portion and the insertion portion is released.

A writing instrument includes a cylindrical outer housing, one end of the outer housing having an outer opening, and an electronic pen body stored in the outer housing. The electronic pen body includes a stylus, one end of the stylus in an axial direction of the stylus serving as a pen tip, and a cylindrical inner housing storing the stylus, the one end of the stylus serving as the pen tip extending from an inner opening at a distal end of the inner housing, the inner opening of the inner housing defining one axial end of a hole extending axially forming a stylus guide that enables the stylus to move axially. In operation, the pen tip of the stylus and a distal portion of the inner housing having the inner opening extend from the outer opening of the outer housing.

A multi-function writing implement includes a pen shaft, a colored pen assembly, and an erasing pen assembly. The colored pen assembly is arranged at one end of the pen shaft. The colored pen assembly includes a cartridge seat, a nib seat, a plurality of colored cartridges, a plurality of relay cartridges, and a plurality of colored ink cotton tubes. The erasing pen assembly is arranged at the other end of the pen shaft opposite to the colored pen assembly. Only one end of the pen shaft may have at least two colors for providing the user to use different colors and the user is not necessary to use two nibs respectively arranged at two ends of the pen shaft by replacing in turn.

A double-head marker pen includes a first penholder, a second penholder and a connecting tube; one end of the first penholder is formed with a first pen head, and one end of the second penholder is formed with a second pen head; and an end of the first penholder away from the first pen head is detachably connected with an end of the second penholder away from the second pen head by the connecting tube.

A handheld implement, configured for example as a writing-instrument, having a shaft that has at least two shaft parts which are releasably connectable together via a plug-in coupling, which have a coupling unit at each front end of the shaft parts. Each coupling unit has a slide that is held immovably in a guide hole open on a face side in the associated shaft part and protrudes beyond the guide hole with a slide portion, the free end of the slide portion is formed as a latching fork that has a latching opening between two fork arms, that the slide portion bears a latching protrusion on its inner side behind the latching fork in the sliding direction, the coupling unit has a guide sleeve that encloses the slide and is guided movably in the guide hole counter to the restoring force of a spring- or rubber-elastic restoring element, and when the front ends, having the coupling units, of two shaft parts are pressed together, the latching fork of one coupling unit is latchable on the latching protrusion of the other coupling unit with at least one of the guide sleeves being pushed back.

A writing, drawing, marking and/or painting utensil or cosmetics implement or input device for contact-sensitive surfaces, wherein the utensil/implement/device includes at least one shank element made of plastics material or a plastics-containing wood substitute. The at least one shank element has a surface, or in that the at least one shank element has a surface which is sheathed in a material layer having a cover surface. The surface of the shank element or the cover surface of the material layer is in the form of a haptic and/or non-slip layer. The haptic and/or non-slip layer has a structure formed in one piece with the shank element and/or the material layer. The structure is formed by corrugation.

A method of coextruding polymeric materials into multiple layers of desired thickness to form a tubular workpiece. The method includes conveying a first polymeric material through a main extruder and a second polymeric material through a coextruder. The second polymeric material has dispersed therein an amount of electrically conductive particles effective to impart electrical conductivity to the tubular workpiece. The method further includes simultaneously extruding the first polymeric material and the second polymeric material through a coextrusion die to form the tubular workpiece. The tubular workpiece is extruded in the form of one or more outer layers having the first polymeric material and one or more inner layers comprising the second polymeric material. A tubular workpiece prepared by the method of coextruding polymeric materials into multiple layers of desired thickness. A system for coextruding polymeric materials into multiple layers of desired thickness to form a tubular workpiece is also provided.
