Abstract:

An apparatus for making crayons is provided. The apparatus includes a base that houses a heating component, a melt pan disposed to absorb heat from the heating component, a mold, and a cover. The melt pan receives crayon material and contains it as the heating component increases the temperature, causing the crayon material to liquefy. The liquefied crayon material can then be drained by the user of the device, into a mold with crayon-shaped cavities. A cover prevents access to the melt pan and the mold during particular operating conditions of the apparatus.

International Classification:

US Classification:

401206, 401198

Abstract:

Ink delivery systems to provide ink from a reservoir to an applicator pad for marking a surface. Ink is stored in a reservoir within a marker body. A valve system controls the flow of ink to the applicator pad to prevent puddling of ink on the marking surface. The reservoir is a hollow body with free flowing ink or may contain a fiber reservoir at least partially saturated with ink. The reservoir may also contain capillary channels and ribs to aid in transporting ink to the valve system. The valve system includes a plug and a spring to bias the plug in a closed position. The plug includes at least one contact surface to contact a housing, and thereby control the flow of ink from the reservoir to the applicator pad. The spring may be a coil spring or a compressible foam-like spring.
