摘要： A marking utensil comprises an elongated body having opposite ends, with the body defining a plurality of outwardly-directed surfaces between the ends. A scale is displayed on at least one surface of the plurality, with at least one surface of the plurality configured for placement along an exteriority of the article to facilitate a measurement thereof. The scale may display U.S. Customary (i.e., inches) and/or Metric International System (i.e., centimeters) Units of measure. A marking tip is located at one end of the body while a reference guide is located at the body's other end.

摘要： A writing, drawing, marking and/or painting utensil or cosmetics implement or input device for contact-sensitive surfaces, wherein the utensil/implement/device includes at least one shank element made of plastics material or a plastics-containing wood substitute. The at least one shank element has a surface, or in that the at least one shank element has a surface which is sheathed in a material layer having a cover surface. The surface of the shank element or the cover surface of the material layer is in the form of a haptic and/or non-slip layer. The haptic and/or non-slip layer has a structure formed in one piece with the shank element and/or the material layer. The structure is formed by corrugation.

摘要： This invention relates to the process for obtaining sheets made from seaweed that, when wrapped around a coal mine, wax mine or ink loads, give rise to the cylindrical and elongated cover of pencil or pen made based on algae, salt, bentonite and water, with a final layer of cotton thread optionally, tinctured with natural plant elements and having seeds at its rear end.The process for the production of films made from algae by heat treatment with the addition of salt and bentonite for making covers of pencil or pen comprises the following steps: i) boiling seaweed containing collagen for gelatinization together with salt and bentonite; ii) poring the gelatinized algae into the bowl and dip a graphite for writing; iii) subjecting to temperature for drying the algae and obtaining sheets; iv) cutting the sheets, according to the size of graphite for writing, leaving a space at the rear end to place the seeds; and iv) wrapping the graphite for writing with pieces of wet sheets to obtain a particular shape.

摘要： A seed-containing crayon includes an elongated member formed of a marking composition to leave a colored mark on a surface when the elongated member contacts the surface. The marking composition is formed of a wax, a pigment, and a plant nutrient that is activated by application of water to the elongated member. Plant seeds are embedded in the marking composition of the elongated member. The crayon can include a paper band that at least partially surrounds the elongated member along at least part of the length of the elongated member in which the plant seeds are embedded.

摘要： A wood-encased pencil for writing, sketching, drawing, and cosmetic purposes includes grip surfaces or grip nubs projecting from at least one surface thereof as handling raised structures. The structures are of a plastic material and are applied in the form of an initially flowable preparation which includes at least one plastic and that later solidifies to give the raised structures. In a first variant, the preparation is anhydrous and is of a radiation-curable plastic. In a second variant, the preparation is, likewise, anhydrous, but its solidification is based on physical drying. For such a purpose, the preparation is of an organic solvent as well as a plastic.
