Abstract: A writing instrument with an input member for pressure-sensitive handwriting at one end, and a removable writing pen on the opposite end of a cylindrical body. A single cap of a diameter smaller than that of the cylindrical body may cover either the writing pen or the input member. The diameter of the cap is smaller that the diameter of the cylindrical body to lessen the chance of it being inadvertently dislodged.

Abstract: A curved ergonomic pen which facilitates writing on vertical surfaces comprises a housing having a barrel portion and a web portion. The barrel has curved inner and outer edges and substantially flat sides. The web is substantially flat and extends along the curved inner edge of the barrel. A curved channel is formed in the barrel in communication with openings in opposite ends of the barrel. A pair of ink cartridges each comprising an ink tube and a tip secured to one end thereof are retractably secured within the channel such that the respective tips generally extend toward opposite ends of the barrel. The pen tips are selectively extendable and retractable through the associated openings in the opposite ends of the barrel. In one embodiment, a note pocket for receiving relatively small sheets of paper is removably securable within a slot extending into an outer edge of the web.

Abstract: A liquid applicator structure which has an application tip fixed to front end of a cylindrical body and a liquid supply assembly built in its rear end. The liquid supply assembly includes a rotatable rod composed of a cylindrical shank-and-operating end and a solid rod having male threads thereon. The rotatable rod is held with an anti-rotation member having a cantilever-like extension. A split slide member having two split extensions is engaged with the rotatable rod at its rear end. One of these split extensions is inserted within the cantilever-like extension of the anti-rotation member and the rotatable rod, thereby preventing the split slide member from rotating. A piston member abuts on the split slide member. Rotation of the rotatable rod causes the split slide member and the piston to advance and drive liquid toward the application tip.

Abstract: A cosmetic applicator embodies two cosmetic applicator elements in a single barrel housing. One applicator element is slidably extendable from retracted position in the housing to extended use position wherein it is extended axially a distance from an opening at one end of the housing. The other applicator element rotatably is axially extended from retracted position in the housing to use position. The operating means by which each element is extended are located in the housing in such manner that the operating means associated with the said other element lies nested in the operating means associated with the first applicator element when that element is retracted. Thus, the length of the housing can be shortened and still accommodate both operating means since they occupy a common length extend in the housing. One applicator element can be a lipbrush and the other an eyeliner.

Handwriting written in this colored ink can be erased by using an eraser comprising a desensitizing compound which makes the colored electron-donating dye colorless.

Abstract: In a writing implement with two cartridges (12,22) the housing is divided in two parts connected together by a pivot. The cartridges are pressed by spring force against cams (14a,24a) which are arranged on the other housing. The cams have such a profile that the writing points (12a,22a) are driven out in the opened position of the housings but retracted in the closed position into the housings. The closing action retracts the writing points into the housings; the opening out action drives out the writing points.

Abstract: A method for making and the composition for an initially erasable ink for a ball point writing instrument which ink is characterized by its initial erasability by ordinary pencil erasers when applied by a ball point writing instrument to an absorbent paper-like writing surface and which thereafter develops permanence.

Abstract: A ballpoint writing instrument containing a supply of ink capable of producing an intense colored line when deposited on a writing paper surface that is capable of erasure within several hours after deposit by the use of a conventional pencil eraser without causing damage to the writing paper surface but which thereafter sets up to produce a permanent non-erasable line. The ink includes an elastomeric polymer such as Cis-1.4 Polyisoprene dissolved in an essentially non-volatile hydrocarbon solvent or plasticizer such as a light mineral oil and a colorant such as pigment particles evenly dispersed in the plasticized elastomeric polymer solution. The elastomeric polymer prevents the pigment colorant from penetrating into the writing paper surface. The preferred ink formulations also avoid or limit the use of volatile solvents which are detrimental to smooth writing characteristics for a ballpoint pen.

Abstract: Disclosed is a ball point ink pen, its ink and its eradicator. The ink is carried at one end of the pen and the eradicator portion is carried at the other. If an error is made, the pen can be reversed and the eradicator used to neutralize the ink. The ink also neutralizes the eradicator so that when one rewrites with the same ink, any remaining eradicator on the paper is neutralized and the original ink acts as fresh ink.
