Definitions

  • the invention relates to a method for producing a writing, drawing, marking and/or painting device or cosmetic device or input device for touch-sensitive surfaces made of plastic or plastic-containing wood substitute, which have a special external shape.
  • Writing, drawing, marking and/or painting devices or cosmetic devices or input devices for touch-sensitive surfaces with a surface that have a special effect are known in principle.
  • Utensils of this type have knobs made from an aqueous plastic dispersion, which improve the utensil in terms of ergonomics and haptics. Such a configuration is intended to prevent the user of the utensil from tiring over long periods of use.
  • a disadvantage of such utensils is that the applied nubs made of aqueous plastic dispersion have to be applied subsequently, ie in a separate and additional work step. Furthermore, the knobs, which are applied in liquid or pasty form, must first harden after attachment or application. This prevents a continuous process and consequently increases the manufacturing cost of such a utensil. Furthermore, it is considered disadvantageous that the applied nubs wear out easily during use, and thus represent an unattractive external detail element and also lose their positive properties in terms of ergonomic advantages.
  • Writing, drawing, coloring or cosmetic pencils which have a non-slip surface are also known from DE 201 16 363 U1 .
  • Such pens are coated with a special varnish that is supposed to make the surface non-slip and easy to grip.
  • the production should be technically simple and economical.
  • Writing, drawing, marking and / or painting equipment that are integrally formed are from DE 102010030539 A1 known.
  • the surface of the shaft element is heated with a laser, which means that the heated plastic emerges from the surface of the shaft element with a change in volume.
  • the disadvantage here is that the method described requires a large amount of energy and is also difficult to control. Each individual structure that is to be generated must be controlled individually. Furthermore, the energy input from the laser beam is sometimes too high, which can result in partial burns on the equipment.
  • a pen in particular a writing or cosmetic pen made of wood or extruded plastic, which has a surface structure that is applied by embossing using a pressing tool.
  • the object of the invention is therefore to create a method for producing writing, drawing, marking and/or painting devices or cosmetic devices or input devices for touch-sensitive surfaces which does not have the disadvantages mentioned and in which the devices have a surface which is particularly advantageous in terms of haptics possess, the devices are manufactured in a continuous process and the haptic surfaces are visually recognizable to the user without changing the primary properties, such as sharpenability, colouration, strength, opacity of the smear and erasability of the device.
  • the object of the invention is that the method can be used to form structures perpendicular to the direction of extrusion without having to use a separate or additional chip-removing method or other manufacturing method.
  • the object is achieved for a writing, drawing, marking and/or painting device or cosmetic device or input device for touch-sensitive surfaces by applying a visually recognizable, raised surface to improve the haptic properties using the corrugation method on the shaft element of the device and is thus formed in one piece with the device.
  • the process of corrugation means the subsequent treatment of an extruded strand with a so-called corrugator.
  • a method for plastic pipes is, for example, from DE 102010056239 A1 known.
  • a freshly extruded strand of plastic is drawn into a corrugator, in which this strand then runs through the mold jaws of the corrugator, forming a corrugated structure in accordance with the configuration of the mold jaws.
  • the strand of plastic is pressed into the cavities of the mold blocks. This can be achieved or supported, for example, by vacuum.
  • the corrugation of a solid body in the form of a writing, drawing, marking and/or painting device or cosmetic device or input device for touch-sensitive surfaces, results in a non-slip surface on the shaft element of the device directly and /or can be formed on a material layer at least partially covering the shaft element, without the manufacturing process having to be interrupted in the process.
  • the advantage here is that geometries can be produced that can otherwise only be produced by means of post-processing or injection molding.
  • the desired properties, namely sharpenability, coloring, strength, opacity of the smear, erasability, etc. are not affected by this.
  • this method forms devices in which the structures and the basic construct are designed in one piece in the form of a shaft, which prevents the haptic and/or slip-reducing layer or structures from becoming detached from the shaft element or basic construct.
  • a haptic and/or slip-reducing surface or layer By forming such a haptic and/or slip-reducing surface or layer, it is achieved that a device designed in this way has better haptic properties.
  • the raised structure makes it immediately clear to the user that the device, which has a special, haptic and/or non-slip surface, enables a more comfortable feeling when in use. A fatigue-free use is possible over a longer period of time.
  • the writing, drawing, marking and/or painting device or cosmetic device or input device for touch-sensitive surfaces produced by the method according to the invention has at least one shaft element made of plastic or a wood substitute containing plastic.
  • the at least one shaft element has a surface or has a surface that is covered with a material layer having a cover surface.
  • the surface of Shaft element or the top surface of the material layer is designed as a haptic and/or anti-slip layer,
  • the haptic and/or anti-slip layer has a structure that is formed in one piece with the shaft element and/or the material layer.
  • the structure formed on the device is formed by corrugation.
  • the at least one shaft element described is present as a pre-strand which is formed by extrusion.
  • the at least one shaft element can also have a material layer applied by means of transverse extrusion.
  • the plastic and/or the plastic portion in the wood substitute of the shaft element is designed as a thermoplastic.
  • the layer of material applied by means of transverse extrusion consists of at least one plastic and/or at least one wood substitute comprising at least one plastic, the plastic being in the form of a thermoplastic.
  • the shaft element and/or the layer of material covering the shaft element can also be designed to be expandable, which is advantageous for the formation of raised structures.
  • the expandable shaft element and/or material layer can have hollow microspheres.
  • the device according to the invention or the preliminary strand or preliminary strand with material layer is produced by a cascaded extrusion.
  • the surface of the at least one shaft element consists of a corrugable plastic, with the corrugable plastic forming the outer structured, haptic and/or anti-slip layer of the device.
  • a deformable material layer is applied to the at least one shaft element, which forms the outer structured, haptic and/or slip-reducing layer of the device by means of raised structures applied by corrugation.
  • the devices constructed in this way can be in the form of a pencil or a colored pencil comprising at least one lead, at least one adhesion promoter and at least one shaft element.
  • the at least one shaft element is in the form of a hollow profile before, in which at least one receiving space for a writing medium is formed or arranged.
  • the receiving space is delimited radially by the at least one shaft element.
  • figure 1 shows a longitudinal section through a writing, drawing, marking and/or painting device or cosmetic device or input device for touch-sensitive surfaces 10 manufactured according to the invention, which has a lead 1 with the diameter m in the center, which is surrounded by a shaft element 2 with the wall thickness s is.
  • the shaft element 2 can be formed, for example, from plastic or a plastic-containing wood substitute.
  • the mine 1 is arranged in the receiving space 5 .
  • a deformable material layer 3 with a minimum wall thickness fn and a maximum wall thickness fh is arranged on the outer side of the shaft element 2 .
  • the height of the structures is given by the difference in wall thicknesses fh and fn.
  • the structures are made using the method of corrugation.
  • the figure 2 a longitudinal section through a further embodiment of a device 10 is shown, which has a mine 1 with the diameter m in the center, which is surrounded by a shaft element 2 .
  • the mine 1 is arranged in the receiving space 5 .
  • the shaft element 2 must be formed from a material which can be extruded and which, after the extrusion process has taken place, still has a temperature suitable for the deforming processing.
  • the shaft element 2 can be made of plastic or a wood substitute containing plastic.
  • the shaft element 2 can be deformed by corrugation and has a minimum wall thickness fn and a maximum wall thickness fh.
  • any type of solid profile or solid body can be provided with raised structures in the corrugation process.
  • the object is achieved according to the invention by a method for producing a writing, drawing, marking and/or painting device or cosmetic device or input device for touch-sensitive surfaces, as defined in claims 1 and 2.
  • thermoplastic comprises at least one polymer from the group of polyolefins or styrenic block polymers with chemical exothermic or endothermic blowing agents.
  • the propellant is selected from the group comprising azodicarbinamide or oxy- to benzenesulfonyl hydrazide.
  • this corrugation does not necessarily use a hollow body, but a solid body.
  • the solid body is encased in a deformable layer, so that only this layer expands into the cavities of the corrugator and thus the outer structure of the device alone is changed by corrugation.
  • the use of a vacuum is not necessary here and would possibly lead to the destruction of the internal structure of the pre-extruded device.
  • the preliminary strand does not necessarily have to be coated with a layer of material for the purpose of corrugation.
  • the shaft element must be designed as a thermoplastic material.
  • an alternative method according to the present invention comprises the steps as defined in claim 2:
  • a raw pencil consisting of lead, adhesion promoter and shaft element if necessary, is extruded to form a preliminary strand.
  • Raised structures are produced on this preliminary strand by means of expansion of the still deformable thermoplastic material of the shaft element through the cavities of the corrugator, the structure being corrugated.
  • the cross-section of the writing, drawing, marking and/or painting device or cosmetic device or input device for touch-sensitive surfaces can take on various shapes - round, square or combinations thereof.
