3 pen

s The invention relates to a pen with at least one lead casing,

6 Pen shaft, pen cap or similar sleeve. Such pens are for example

7 Colored pencils with a wooden or plastic coating or pencils with axially

8 retractable lead, such as cosmetic pencils. In addition to the shape of such pencils, their

9 Colouring and surface finish play an important role in their acceptance at

10 Market.

12 The object of the invention is to provide a pen with a visually appealing surface

13 design to propose.

15 This object is achieved by a pen having the features of claim 1.

16 There are then several recesses in the peripheral surface of the sleeve,

&igr;? which have a - compared to the material of the sleeve - different colour and on the sleeve

18 senmaterial adhering filling material, whereby the surface of the filling material

19 terials are flush with the peripheral surface. The recesses are thus filled so that

20 an overall smooth surface is created. The mechanically integrated into the peripheral surface

21 The recesses in the sleeve can be designed as desired, for example

22 in the manner of a guilloche, so that in connection with its filling with

23 a different coloured material visually very appealing surface design

24 pins are possible. The filling of the recesses is carried out according to

25 claim 6 in a technically simple manner by applying the cover

26 se a coating is applied over the circumference of the sleeve, which

27 covers the sleeve's peripheral surface and fills the depressions. The layer is then removed - if necessary after hardening - until the original peripheral surface is visible.

31 A suitable coating can be achieved with an acrylic-based paint

32 (claim 4). Such a varnish adheres to very different sleeve

&igr; materials such as wood, metal or plastic. It is well suited for

2 sleeves made of ABS.

4 The recesses in the peripheral surface are preferably grooves, the production

5 The layer is applied by spraying or painting on a varnish. The removal

6 The layer is preferably applied by grinding.

a The invention will now be described with reference to an embodiment shown in the accompanying drawings.

9th embodiment is explained in more detail. They show:

11 Fig. 1 a section of the shaft sleeve of a cosmetic pencil and

12 Fig. 2 shows a section of the sleeve wall according to the line H-II in Fig. 1.

14 In Fig. 1, a plastic, for example an acrylonitrile-butadiene

15 styrene copolymer (ABS) sleeve 1 is shown in sections. In its

16 Wave-shaped grooves 4 &igr;? are introduced into the circumferential surface 2 essentially in the longitudinal direction 3. For reasons of graphic design, only three of these grooves are shown.

18 The grooves are filled with a filling material 5, whereby the surface 6 of the

19 filling material is flush with the peripheral surface 2 of the sleeve 1. The filling material is

20, for example, a 1-component acrylic-based paint.

22 To produce the sleeve shown in Fig. 1 and Fig. 2, proceed as follows:

23 that first the peripheral surface 2 of the sleeve 1 is guilloched, i.e.

24 possibly intertwined grooves are engraved. Then the casing

25 se 1 with the above mentioned acrylic varnish preferably by spraying.

26 hen. The resulting lacquer layer covers, as can be seen in the left half of Fig. 2,

27, the peripheral surface 2 remaining after guilloche engraving

28 of the sleeve 1 and the grooves 4. The layer 7 thus produced is in a subsequent

29 following machining step so that the original circumference

30 surface 2 reappears, leaving an essentially smooth shell.

31 surface is created.

Claims (8)

1. Pen with at least one sleeve ( 1 ) serving as a lead casing, pen shaft, pen cap or the like, characterized in that in the peripheral surface ( 2 ) of the sleeve there are several depressions which are filled with a differently colored filling material ( 5 ) adhering to the sleeve material, the surface ( 6 ) of the filling material ( 5 ) being flush with the peripheral surface ( 2 ) of the sleeve ( 1 ). 2. Pin according to claim 1, characterized in that the recesses are grooves ( 4 ) or slots. 3. Pin according to claim 2, characterized in that the grooves ( 4 ) are wave-shaped and extend substantially in the longitudinal direction of the pin ( 3 ). 4. Pen according to one of claims 1 to 3, characterized in that the filling material ( 5 ) is a one-component colored varnish based on acrylate. 5. Pen according to one of claims 1 to 4, characterized in that the sleeve ( 1 ) consists of an acrylonitrile-butadiene-styrene copolymer. 6. Pen according to one of claims 1 to 5, characterized in that the filling material is formed by a layer ( 7 ) adhering to the sleeve material, which layer is applied to the peripheral surface ( 2 ) of the sleeve ( 1 ) while filling the depressions and is removed to such an extent that the original peripheral surface ( 2 ) is visible again. 7. Pen according to claim 6, characterized in that the recesses are grooves ( 4 ) engraved in the sleeve ( 1 ). 8. Pen according to claim 6 or 7, characterized in that the layer ( 7 ) is a varnish sprayed or painted onto the sleeve ( 1 ).
