Abstract
Abstract Disclosed are multi-color marking implements (i.e. crayons) having variegated color patterns, and a method and apparatus for their manufacture involving consecutively casting small amounts of molten crayon-like materials into suitably shaped molds at specific temperatures. The marking implements have a multiplicity of discretely-colored regions of random shape, randomly distributed in the implement. In addition, the marking implement may include a multiplicity of non-discretely colored regions resulting from a blending of colors from two discretely-colored regions. Optionally, the multi-color implement may be provided in a transparent lipstick type container that may serve as the mold in the casting process.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
118 words
A method for making a multi-colored marking implement comprising providing molten wax-like materials of at least two different colors, dispensing a metered amount of a first of said molten wax-like materials while at a first temperature into a mold and after a predetermined cooling period dispensing a second of said molten wax-like materials while at a second temperature into the mold, so that the two dispensed materials form a discretely-colored material region and form a non-discretely-colored region of blended color substantially randomly distributed in the discretely colored material region, and repeating the above steps a multiplicity of times so as to form a marking implement having a variegated pattern of substantially randomly distributed discrete and blended colored regions.
Claim 2
Independent Claim
118 words
A method for making a multi-colored marking implement comprising providing molten wax-like materials of at least two different colors, dispensing a metered amount of a first of said molten wax-like materials while at a first temperature into a mold and after a predetermined cooling period dispensing a second of said molten wax-like materials while at a second temperature into the mold, so that the two dispensed materials form a discretely-colored material region and form a non-discretely-colored region of blended color substantially randomly distributed in the discretely colored material region, and repeating the above steps a multiplicity of times so as to form a marking implement having a variegated pattern of substantially randomly distributed discrete and blended colored regions.
Claim 3
Dependent Claim
46 words
The method according to claim 1 and including the step of providing molten materials of at least three different colors and repeatedly dispensing metered amounts of each while each material is at a selected temperature and providing a predetermined cooling period separating consecutive dispensings of materials.
Claim 4
Dependent Claim
12 words
The method according to claim 2 wherein the materials are sequentially dispensed.
Claim 5
Dependent Claim
37 words
The method according to claim 2 wherein the materials include pigments or dyes which form a color selected from the group consisting of yellow, dark blue, orange, purple, red, green, light blue, pink, carmin red and salmon.
Claim 6
Dependent Claim
49 words
The method according to claim 4 wherein the materials are dispensed at the following temperatures: yellow 80° C., dark blue 80° C., orange 105° C., purple 75° C., red 75° C., green 85° C., light blue 90° C., pink 80° C., carmin red 65° C., and salmon 80° C.
Claim 7
Dependent Claim
20 words
The method according to claim 1 wherein the materials are cast into a cylindrical mold having an inwardly convex base.
Claim 8
Dependent Claim
19 words
The method according to claim 6 wherein the mold comprises an inner hollow cylindrical member of a lipstick-type container.
