The invention relates to a pen with a sleeve containing a brushable body, in particular a cosmetic stick, according to the preamble of claim 1.

Such cosmetic pencils are available in numerous variants, these are generally disposable items.

In the usual embodiment (DT-AS 1 254 304) the spreadable body sits in one of the sleeve by twisting it a handle part opposite a screw part screwable version. A high helix thread ensures that it can be extended from the sleeve over its entire length with a short turn. Comes from careless handling It is easy to break off the unprotected body after it has been unscrewed.

According to another known embodiment (DGBM 7500699) the spreadable body is in one over its entire length Cartridge housed, which is releasably attached to a handle part. At the opposite end of the handle part is arranged a screw part which protrudes into the interior of the handle part. Engages in an internal thread of the screw part a screw bolt, which can be extended against a piston when the screw part is turned, which is the spreadable Body in front of him. The piston is sealed against the inner wall of the cartridge.

The last-mentioned embodiment offers a break-proof one Support of the spreadable body in that it can be increasingly pushed out of the cartridge as required; Without a cap, however, it requires at least 6 components, which makes such a mass-produced article considerably more expensive to manufacture.

In contrast, the invention is based on the object of providing a simple structure, that is to say with as much as possible pen, especially cosmetic pen

to create, which also offers the advantages of the second-mentioned embodiment.

According to the invention, this object is achieved in that the spreadable body is filled into the screw part, which is attached to an inside of the handle part The stamp can be screwed on. Without counting the cap, this solution manages with a total of only three components. If you neglect the use of materials, the result is as a result, compared to the second-mentioned known embodiment, a cost saving of 50%.

The manufacture of the pen according to the invention can be continue to simplify by

that the plunger has an external thread, the screw has an internal thread, that the stamp is mounted riffteil press fit at its inner end in ^G, that the punch is designed as a closed at the outer end of the hollow part, and that the screw adjacent piercing terminals his in the grip part The end has individual thread webs protruding on the inside.

These and other features mentioned in the subclaims enable the production of all individual parts as injection molded parts made of plastic, preferably polystyrene. A softer plastic, such as polyethylene, is also suitable for the stamp. This makes the realization easier the press fit for its attachment inside the handle part.

Fig. 5 shows the stamp

According to FIG. 1, the pin consists of the components handle part 1, screw part 2, punch 3 and cap 4. In the interior of the screw part 2, the spreadable body 5 is filled. Only the tip 6 of the spreadable The body 5 projects beyond the screw part 2. The punch 3 has only one over its entire length Partially drawn external thread 7 », preferably as a flat thread. In this external thread 7 attack the inside of the screw part 2 protruding thread webs 8 (Figure 2). The length between the thread webs 8 and the nearer end of the screw part 2 is used to center and facilitate assembly when - screwing in the screw part 2 into the inside of the handle part 1 and thus onto the stamp 3 By turning the screw part 2, the free front end 9 of the punch 3 penetrates increasingly into the interior of the Screw part 2 and thus pushes the spreadable body 5 increasingly out of screw part 2 at its other end out.

The stamp 3 "has on its" with respect to the handle part 1 inner end of a collar 10, which is deformed when pressed into the handle part 1. They push each other inwardly projecting ribs 11 of the handle part 1 into the collar 10, so that there is a tight fit. The cap 4- becomes easy when the pen is not in use partially attached to the recess 12 of the handle.
