Writing pens, in particular fiber-tip pens

The innovation concerns a pen, especially Fiber-tip pen, with protective cap, the b, pushed over the pen tip on the pen shaft one arranged on the inside on the one hand and on the outside on the other on the pen Bracket springs in elastically. According to the innovation, it is assumed that known fiber-tip pens of this type whose writing shaft consists of a sleeve made of plastic and has a ring-shaped e.g. bead star " term increase is provided, while an annular recess is arranged on the inside of the protective cap is, in which the annular bead or the like. When sliding the cap over the pen tip under easier Application of pressure jumps in and out of the holder caused by it, by applying low tensile force Loosen again läifc * The holder of the protective cap in this way has the disadvantage that the injection molding of the sleeve forming the pen shaft made of plastic with an annular bead surrounding the sleeve or the like. Difficulty removing from the mold

can be accomplished

According to the innovation, the seat holder is in the case of a special pen designed in the manner described the protective cap also by an outer annular elevation and an annular recess in the protective cap causes. The innovation is that the annular outer elevation is on a pen tip is arranged, which is raging in the auc of a continuous en sleeve. Pen sleeve inserted and connected to it by welding or in some other way. The innovation is dem Known pen-related disadvantage eliminated in that the one part of the holder of the Hing bead forming the protective cap is not located on the shaft sleeve but on the outside of the pen tip, which can be easily produced by injection molding with a hanging bead or the like without any difficulties in removing the mold. must be taken into account. Instead of an elevation that re-enters an annular recess, as Retaining means for the protective cap also consider other surface configurations that can be achieved by elastic Jump in to bring the parts together.

The innovation let in the drawing on the example of? Aeevaohreibers veransohaulioht.

The illustrated fairy pen consists of one continuous casing forming the earring pin 1 made of plastic and a pen tip 2 from the same material that was used when assembling the pen with a lower attachment 2a in the Sohafthtilse 1 and connected to it e.g. duroh Bohweiß will. Hit 3 is called a protective cap.

On the lower rope 2a of the epithelial body there is a annular bead-like elevation 4- provided * during an annular recess 5 is arranged in the inner wall of the protective cap, which when the Protective cap over the pen slots under lower Application of pressure springs in elastic and holds the cap in its seat, which is in the same way by light Remove the cable again from the sobxeibstiftsplzze

The price increase is primarily intended for one-story Writing pens, especially fiber pens, which do not use up their supply of writing dye can continue to be used and therefore to be thrown away are determined.

Claims (1)

Claim to protection. Writing pen, especially fiber-tip pen, with protective cap, the pen tip sitting on the pen shaft with an inside when it is pushed over arranged annular recess on an outside The ring-shaped elevation provided for the pen springs in elastically with the application of slight pressure, characterized in that that the annular outer elevation (4) is arranged on (jiner pen tip (2), which is in the from a continuous sleeve (1) existing pen shaft inserted and with it by welding or in another V / siss is connected.
