Description

"Cardboard and crayon for design zv / corner"

The innovation "concerns a cardboard box and a drawing pen for design purposes, with which sharp outlined drawings and the finest lines are to be produced.

Very often it is necessary to make one first Drafting of drawings or posters or other promotional items of a graphic type legal letters or legal lines to use «So far this has been almost exclusively with relative To carry out complicated masks, although the masks themselves were not easy to make. It gets complicated

ö the thing when multicolored drafts are to be made. The hiring avoids all these disadvantages and gives the advantage that a first draft can be produced with the simplest means _s in which not only hegative letters are sharp outlines, but also positive letters, even in several colors, are shown just as sharply. Of course, this good illustration is not limited to letters, but any figurative drawing can be produced just as easily and still in the finest details.

The hiring "consists in that on the to be used First surface a pore-tight, smooth layer on the cardboard a material known per se and then a further layer of a casein emulsion paint is applied.

A mandatory implementation of the fire is that a known plastic coating is used as the pore-tight layer, the plastic being hydrophilic Properties «

The drawing shows a cross section through a cardboard box, with the base material! Cardboard material, a plastic layer 2 is applied, which has hydrophilic properties. This layer is pore-tight and consists of a thin plastic film welded onto the base material 1 on this plastic layer is another layer 3 made of a casein emulsion paint Because this color emulsified itself as one in water Color, it can be the hydrophilic plastic layer wet, which is very important for an even coating with paint «

FIG. 2 shows a section through a drawing pen. The pen is made of round material with a has exactly circular cavity 5, vrodurch a Uniformly strong edge 6 forms. With this edge 6 is then By choosing different thicker pens you can Lines of different thickness can be drawn. For very fine lines, a steel or other point is sufficient can be made of metal, but it is very useful as a material for a no longer elastic, Instead, use relatively hard plastic, so that the pin can then be manufactured using a compression molding or injection molding process.

For the production of drawings, the pen is moved over the drawing surface, with the plastic pen its G-rat 6 on the contact surface with the cardboard removes the layer of color. By using the casein

Emulsion paint results in very sharp drawing contours Attractive effects can be achieved here achieve. that one produces the carrier cardboard in a different color than the color guide 3 »so that now two different colors stand next to each other · In general, however, a white background will be used for one color, since then the negative recessed lines or figures can be created in a different color. with which the relevant cardboard surface is sprayed or brushed over. You can now solve the Gasein-color layer off, so remains in the place of the cardboard, where the drawing was, i.e. where there was no more casein color, the paint color is and the result is that of a different color BildoDortjWO the lacquer color is on top of the casein color, it will with the casein color. Even with this writing or drawing consisting of the lacquer color, there are still completely sharp contours, because the original of the emulsion paint was also sharp-edged.

The main advantage of the cardboard box is that it can be remove the emulsion paint completely with the pen, leaving the pure color of the cardboard box This can only be achieved by the Layer 2 of the cardboard does not have any pores into which the emulsion Farfee The paint can hardly be removed from the pores, unless by scraping with a sharp blade, which of course is much more cumbersome. In addition, the hydrophilic property of the plastic is necessary for the application of the paint.
