DESCRIPTION:
BRIEF SUMMARY
The invention concerns a cosmetic pencil having a casing shank portion, a casing front portion connected to the casing shank portion, and a drive element which is provided for moving a cosmetic stick in relation to a casing opening of the casing front portion and which is in the form of a tubular stick holding member which is axially movably arranged in the casing front portion, wherein the cosmetic stick which projects with an application portion out of the tubular stick holding member is fixed with a rear fixing portion in the tubular stick holding member and the application portion of the cosmetic stick extends in a play-free condition through the casing opening of the casing front portion.
DE 37 28 427 Cl discloses a cosmetic pencil having a casing shank portion and a casing front portion connected to the casing shank portion, as well as a drive element for moving a cosmetic stick in relation to a casing opening of the casing front portion. That known cosmetic stick is provided either with a cast cosmetic stick or with an extruded cosmetic stick. In the forward feed movement, the cosmetic stick performs not only a forward feed movement relative to the casing front portion, but at the same time a rotary movement, and that is found to cause problems. The same applies to the cosmetic pencil known from GB-A 956 651. In that case also the cosmetic stick, relative to the casing front portion, performs not only a forward feed movement but at the same time also a rotary movement. In addition, in the case of the cosmetic pencil of the last mentioned kind, it is necessary for the cosmetic stick to be inserted into and fixed in a fixing portion which is provided for receiving it and which is disposed at the front end of a screwthreaded spindle. The operation of fitting the cosmetic stick is correspondingly complicated and expensive, in the case of that known cosmetic pencil.
A cosmetic pencil in the form of a lipstick is known from DE 37 11 036 Al. In the case of that lipstick, when it performs its forward feed movement the cosmetic stick portion admittedly does not perform a troublesome rotary movement in relation to the casing front portion, but between the edge of the casing opening of the casing front portion and the peripheral surface of the cosmetic stick portion there is a gap which corresponds to the wall thickness of the holding member for holding the cosmetic stick portion and which is found to cause difficulties.
DE 32 15 215 C2 describes a cosmetic pencil having a casing shank portion and a casing front portion connected thereto, and a drive element for moving a cosmetic stick in relation to a casing opening of the casing front portion, wherein that cosmetic pencil is only suitable for moving the cosmetic stick forwardly out of the casing opening. A return movement of the cosmetic stick back into the casing is not possible with that known cosmetic pencil.
A cosmetic pencil of the kind set forth in the opening part of this specification is known from U.S Pat. No. 4 820 070. That publication gives no information about the diameter of the cosmetic stick. It is clear however that, with that known cosmetic pencil, the tubular stick holding member is of a length which is substantially shorter than the longitudinal extent of the casing front portion of that cosmetic pencil. Furthermore, in that case the application portion of the cosmetic stick has a peripheral surface whose diameter is smaller than the outside surface of the stick holding member. There is therefore a step at the location between the stick holding member and the application portion of the cosmetic stick.
The object of the present invention is that of providing a cosmetic pencil of the kind set forth in the opening part of this specification, in which a thin cosmetic stick can be displaced out of the casing front portion and back into the casing front portion, with the thin cosmetic stick being disposed in a play-free condition in the casing opening.
In a cosmetic pencil of the kind set forth in the opening part of this specification, in acco
