ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention deals with the field of decorative writing instruments and methods for making uniquely decorative surfaces on the barrels thereof. Generally it is advisable that a decoratively coated writing instrument be also functional in that it is capable of easily being gripped and used in the normal manner as any other writing instrument. Many decorative barrel implements or coatings do not provide a functional surface. The present invention is unique in that pencils make with this process provide a very decorative iridescent frosted type appearance and texture while at the same time being completely functional and easily grasped and in fact enhancing the gripping characteristics of the barrel when a user utilizes the writing instrument in the normal manner.

SUMMARY OF THE INVENTION
The present invention discloses a unique method of the manufacturing of a writing instrument where the instrument ultimately has a glitter coated barrel with a unique frosted appearance. Initially the instrument is provided with a main body preferably defining a wooden barrel extending therearound with a writing tip at one end. The wooden barrel preferably has a diameter of approximately 6.9 millimeters in order to be less than the standard size of such writing instruments by an amount equal to the thickness of the base colorant coat and the layer of adhesive material with deposited glitter after curing in order to provide a final barrel diameter approximately equal to the standard size. In this manner the writing instrument can be handled in the conventional manner and is not overly large in diameter and also allows use with conventional pencil sharpeners which are designed to sharpen pencils of approximately 7.75-7.8 millimeters in diameter.
Initially the wooden barrel has a base coat applied thereto of a colorant which preferably is a lacquer paint. This base colorant is preferably relatively dark and is certainly darker than the final overall desired color such that subsequent coats and including the adhesive will mask a portion of the color. It is necessary that the base colorant be significantly darker than this final desired color.
The layer of adhesive is then applied thereon by brushing or spraying over the base coat of colorants onto the barrel of the writing instrument. This adhesive material preferably comprises a polyvinyl acrylic glue composition which includes materials useful as adhesives for both wood and plastics. Prior to curing of this adhesive layer a glitter is deposited thereon preferably in an electrostatic manner. Such glitter deposition is called electro flocking and is achieved by placing a voltage differential between the dispensed glitter and the pencil itself which tends to attract the glitter into contact with the uncured adhesive layer on the pencil or writing instrument to achieve complete coating thereof preferably of the thickness of approximately one particle.
This glitter so deposited preferably is partially translucent to allow portions of the base colorant to be visible therethrough. The glitter preferably will be of a mylar material and preferably be iridescent. This iridescent mylar glitter provides a frosted appearance of the writing instrument coating when finally cured. A cover coat or fourth coat of preferably translucent or transparent material can be applied over the glitter-coated barrel to enhance adherence. This cover coat can be made with a clear adhesive material or can be a conventional clear lacquer or enamel paint material. Such cover coat is extremely thin and does not significantly affect the dimensions of the barrel.
Preferably the individual glitter particles are of a size approximately 0.08 millimeters but in any case less than 0.1 millimeters. This mylar glitter is preferably at least partially transparent to an extent to allow approximately 35% of the intensity of the base colorant to be visible therethrough after curing of the layer of adhesive in which it is embedded.
The adhesive material is then cured preferably by heating within an oven to affix the glitter and the adhesive material together with respect to the colorant coated barrel of the writing instrument with the base paint layer and the cured glitter covered adhesive layer being of approximately 0.425 to 0.45 millimeters in thickness. In this manner the final writing instrument diameter after curing of the adhesive will be approximately 7.75 to 7.8 millimeters since the base barrel is 6.9 millimeters in diameter.
It is an object of the present invention to provide a writing instrument having a glitter coated barrel wherein the glitter coating is iridescent.
It is an object of the present invention to provide a writing instrument having a glitter coated barrel wherein the glitter coating the writing instrument is formed of mylar.
It is an object of the present invention to provide a writing instrument having a glitter coated barrel wherein a base colorant is painted with a lacquer paint beneath the glitter and the glitter adhesive layer to facilitate partial viewing thereof through the partially translucent glitter.
It is an object of the present invention to provide a writing instrument having a glitter coated barrel wherein an initial writing instrument barrel of 6.9 millimeters becomes a final barrel of 7.75-7.8 millimeters after applying of the first layer of base colorant, the second layer adhesive and the third layer of glitter thereto and curing.
It is an object of the present invention to provide a writing instrument having a glitter coated barrel wherein sharpening with a conventionally sized pencil sharpener is possible.
It is an object of the present invention to provide a writing instrument having a glitter coated barrel wherein the glitter is firmly adhered to the adhesive.
