Filed:

Aug 9, 2001

Appl. No.:

09/925813

Inventors:

Wolfgang Witz - Elmhurst IL
Gerold D. Anderka - Ellerbek, DE
Bernd Bastiansen - Wedel, DE
Ralf Polley - Wedel, DE

Assignee:

Sanford L.P. - Freeport IL

International Classification:

B43K 500

US Classification:

401199, 401198

Abstract:

A free ink marking instrument for dispensing a fluid is disclosed. The instrument includes a feeder, a passage of reduced capillarity surrounding the feeder for conveying at least one of fluid and air to the reservoir during an increasing pressure differential between air in the reservoir and the atmosphere, a porous buffer configured for storing ink during periods of a decreasing pressure differential between air in the reservoir and the atmosphere, and a divider tube separating the buffer and the passage along a majority of the length of the buffer. The fluid and air may enter the feeder through a minor surrounding portion of the buffer during the period of the increasing pressure differential. An ink and air conveyor for use in a free ink marking instrument is also disclosed. A method for compensating for changes in ambient temperature and pressure in a free ink marking instrument is also disclosed.

International Classification:

B43K 804

US Classification:

401198

Abstract:

A free ink marking instrument for dispensing an ink, including a housing, a reservoir for storing ink within the housing, a feed tube to convey ink communicating with the reservoir, a tip disposed within the feed tube for conveying ink to a substrate at a marking end of the tip, a porous buffer disposed within the housing adjacent the feed tube and configured for storing ink during periods of a decreasing pressure differential between the reservoir and the atmosphere, and bubble separation area in the form of either a hole in the feed tube or a hole or passage formed between the feed tube and the tip, is disclosed.

B43K 7/02

US Classification:

401 4, 401209, 401217

Abstract:

A free ink roller ball pen for dispensing low viscosity inks containing pigments that are prone to sedimentation. The instrument contains an ink reservoir chamber, a nib chamber provided with a roller ball socket assembly, a pressure equalization overflow chamber for the low viscosity ink, and a special agitation system for the ink reservoir and nib chamber. The agitation system comprises a weight, with a cross section smaller than the interior of the nib chamber, connected to a wire having a diameter smaller than the back inner diameter of the ball socket assembly. The length of the weight and its confinement are selected to provide for a predetermined stroke, on shaking the pen, that sweeps out the internal space of the nib and also the back of the roller ball assembly, to re-disperse any pigment that has precipitated.

US Classification:

239340, 239344, 239346

Abstract:

An airbrush apparatus for use in generating a design on a desired object is disclosed. The apparatus and method of use are disclosed wherein the airbrush apparatus comprises a housing, boom, and sprayer head. A fluid to be applied is contained in individual cartridges and is drawn out by a vacuum effect caused by air that is being pumped from the housing across a feed tube which is in fluid communication with the cartridge.

Assignee:

Crayola LLC - Easton PA

International Classification:

B43K 5/00

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.
