Description

Der Becher 3 hat Zapfen 11, von denen jeder einen Längsschlitz 13 der Innenhülse 1 durchsetzt und in einen schraubenförmigen Schlitz 14 der Außenhülse 2 eingreift. Dies hat zur Folge, daß die gegenseitige Verdrehung der beiden Hülsen die axiale Verschiebung des Bechers 3 relativ zu den Hülsen bewirkt. The cup 3 has pins 11, each of which penetrates a longitudinal slot 13 of the inner sleeve 1 and is in a helical slot 14 of the outer sleeve 2 engages. As a result, the mutual Rotation of the two sleeves causes the axial displacement of the cup 3 relative to the sleeves.

Das Ende der Innenhülse 1, aus der der Lippenstift austritt, weist eine Innenwulst 17 auf, deren Durchmesser D₁ kleiner als der Durchmesser D₂ der Innenhülse ist. Des weiteren ist die ringförmige Innenfläche dieser Wulst konisch gestaltet, wie in der F i g. 1 mit dem Winkel α angegeben ist.The end of the inner sleeve 1 from which the lipstick emerges has an inner bead 17, the diameter D _{1 of which is} smaller than the diameter D _{2 of} the inner sleeve. Furthermore, the annular inner surface of this bead is designed conically, as in FIG. 1 is indicated with the angle α.

Die Schutzhülse 5 hat einen Außendurchmesser, der nur wenig kleiner als der Innendurchmesser Z)₁ The protective sleeve 5 has an outer diameter which is only slightly smaller than the inner diameter Z) ₁

der Wulst 17 ist. Das den Becher 3 umfassende offene Ende der Schutzhülse 5 weist zwei Ausstülpungen 19 und 19' in Form von Nocken auf, deren Außenabstand wenig kleiner als der Innendurchmesser /)g der InnenhUlse 1 ist,the bead is 17. The open end of the protective sleeve 5 encompassing the cup 3 has two protuberances 19 and 19 'in the form of cams, the outer spacing of which is a little smaller than the inner diameter /) g of the inner sleeve is 1,

Um die Möglichkeit einer Zerstörung des Lippenstiftes 4 während des Abslreifens der durchsichtigen Schutzhülse S zu vermeiden, ist bei der dargestellten AusfUhrungsform das offene Ende der Schutzhülse auf eine einen verringerten Durchmesser aufweisende Partie 22 des Bechers 3 aufgesetzt. Bei dem dargestellten Beispiel ist der Außendurchmesser dieser Partie 22 gleich dem Innendurchmesser D„ der Schutzhülse S. Das offene Ende der Schutzhülse 5 weist innen eine Erweiterung 23 auf, deren axiale Länge kürzer als die der Partie 22 verringerten Durchmessers des Bechers 3 ist.To avoid the possibility of the lipstick 4 being destroyed while the clear To avoid protective sleeve S, in the embodiment shown, the open end of the protective sleeve placed on a portion 22 of the cup 3 having a reduced diameter. With the one shown For example, the outside diameter of this part 22 is equal to the inside diameter D "der Protective sleeve S. The open end of the protective sleeve 5 has an enlargement 23 on the inside, the axial Length is shorter than that of the portion 22 of reduced diameter of the cup 3.

Die Schutzhülse 5 ist auf ihrer ganzen Länge gespalten und dadurch in mindestens zwei nebeneinanderliegende Segmente unterteilt. In dem dargestellten Beispiel sind nur zwei Segmente vorhanden, was heißt, daß die Schutzhülse auf ihrer ganzen Länge durch eine durch ihre Achse hindurchgehende, geometrische Ebene 26 gespalten ist. Vorzugsweise sind an Stelle der Ecken am Ende jeder Schutzhülse 5 in der Nähe des Bechers 3 Abschrägungen 27.The protective sleeve 5 is split over its entire length and thereby into at least two adjacent ones Divided into segments. In the example shown, there are only two segments, what means that the protective sleeve has a geometric shape extending through its axis over its entire length Level 26 is split. Preferably, instead of the corners at the end of each protective sleeve 5 in near the cup 3 chamfers 27.

Das Etui arbeitet wie folgt: Im ungebrauchten Zustand, wie er in der F ig. 1 dargestellt ist, bedeckt die Schutzhülse 5 den Lippenstift 4. Beim ersten Gebrauch des Etuis dreht man den Manövrierknopf 8 relativ zur Innenhülse 1, wodurch in der üblichen Weise der Becher3 im Sinn des Pfeils/ (Fig.2) angehoben wird, Damit ist das gleichzeitige Austreten des Lippenstifts 4 und der Schutzhülse S verbunden. The case works as follows: When not in use, as shown in Fig. 1 is shown covers the Protective sleeve 5 the lipstick 4. When using the case for the first time, turn the maneuvering knob 8 relative to the inner sleeve 1, whereby the cup3 is raised in the usual way in the direction of the arrow / (FIG. 2) is, so that the simultaneous emergence of the lipstick 4 and the protective sleeve S is connected.

Sobald die Ausstülpungen 19 und 19' der beiden Segmente der Schutzhülse mit der konischen Partie der Wulst 17 der Innenhülse 1 zur Berührung kornmen, erfahren die Segmente einen gegen die Achse des Etuis gerichteten Stoß, und da die erweiterte Partie 23 des offenen Endes der Schutzhülse zwischen diesem Ende und der Partie 22 mit verringertem Durchmesser des Bechers einen kleinen Raum 20 frei läßt, wird jedes Element im Sinn des Pfeiles/, (F i g. 3) geschwenkt. Die Abschrägungen 27 verhüten jede Störung dieser Schwenkbewegung.As soon as the protuberances 19 and 19 'of the two segments of the protective sleeve with the conical part the bead 17 of the inner sleeve 1 kornmen to contact, the segments experience one against the axis of the case-directed push, and since the widened part 23 of the open end of the protective sleeve between this end and the portion 22 with reduced diameter of the cup a small space 20 free each element is pivoted in the direction of the arrow /, (FIG. 3). Prevent the bevels 27 any disturbance of this pivoting movement.

Daraus ergibt sich, daß die einfache Bewegung des Bechers 3 im Sinn seines Austrittes von selbst das Auseinanderspreizen der Segmente der Schutzhülse 5 und ihr Abwerfen herbeiführt, ohne daß, wie dies bei den früheren Modellen der Fall war, eine leichte Rückwärtsbewegung des Bechers erfolgen muß.It follows that the simple movement of the cup 3 in the sense of its exit by itself that Spreading apart the segments of the protective sleeve 5 and causing them to be thrown off without, as is the case with was the case with earlier models, a slight backward movement of the cup must be made.

Die Zahl der Segmente, aus denen die Schutzhülse besteht, kann mehr als zwei beiragen; die Ausstülpungen dieser Segmente können einen kontinuierlichen Kragen bilden, wenn an Stelle der Wulst der Innenhülse Ausstülpungen vorgesehen werden, deren Zahl der der Segmente entspricht und die gegen die Standorte der Seitenhalbierenden dieser Segmente im Augenblick ihres Abstreifens gerichtet sind. Im übrigen kann das Etui auch an Stelle einer Drehhülse mit einer einfachen Hülse mit mindestens einem Längsschlitz bestehen, durch den nach außen ein Griffzapfen des Bechers tritt. Außerdem können die Segmente der Schutzhülse ineinandergreifen, um eine bessere Abdichtung beim Gießen des Stiftes zu sichern.The number of segments that make up the protective sleeve can be more than two; the protuberances these segments can form a continuous collar if in place of the bead of the inner sleeve Protuberances are provided, the number of which corresponds to that of the segments and against the Locations of the bisectors of these segments are directed at the moment of their stripping. Furthermore the case can also be used instead of a rotating sleeve with a simple sleeve with at least one longitudinal slot exist, through which a handle pin of the cup occurs to the outside. In addition, the segments of the protective sleeve interlock to ensure a better seal when casting the pen.

The invention relates to a case for a lipstick and the like with an outer one with screw threads provided as well as an inner sleeve concentric to it, equipped with longitudinal slits, in the a lipstick-carrying cup is axially displaceable with radial pins through the Longitudinal slots engage in the screw threads and a diminished one at the lipstick end of the shaft Has diameter on which a transparent, lipstick-covering cap sits, whose open end with its inner wall stands out from the shaft end and the outer wall parts a larger diameter than the outlet mouth, which is also larger than the outer dimension of the cap having an inwardly retracted sleeve flange, with sleeve flange and outer Cap end wall parts have a locking function with one another in the extended state of the pin.

In the case of a known case for a lipstick, which is to be stripped off before the first use, transparent cap is covered, the outer sleeve has an inward at its free end directed, obliquely ending flange, the inner diameter of which is smaller by a small amount is than the outer diameter of the cylindrical portion of the cap. The cap lies with its lower The end of the lipstick-carrying cup and protrudes a little with its lower edge surface beyond the cup area where it rests. If after the first use of the The lipstick covered with the cap is fully extended, the inner flange of the outer sleeve engages under the Edge surface of the cap. If the lipstick is now drawn in again, the cap is pushed through the inner flange stripped from the lipstick.

The invention proposes that in the case for a lipstick and the like described above Cap is longitudinally geieilt in at least one axial plane and the cap segments formed thereby after abutment of their end wall parts on the sleeve flange Axial displacement of the pin can be spread apart and ejected.

This construction has the advantage that a multi-part one is used to spread the segments Protective cap considerably less forces and shorter working distances are required than with the axial withdrawal of a sleeve from a pin. Furthermore, the new construction achieves that in order to remove the protective cap of the lipstick after pushing it completely out of the case no longer a short one, as with the well-known case Piece must be turned back - which undoubtedly simplifies handling for the user of the case.

For a better understanding of the invention, it is explained below with reference to the drawing described, which is for example, but not limiting, an embodiment of a case. In detail shows

F i g. 1 a longitudinal section through the closed case,

F i g. 2 the same case during the outward movement of the pen for the purpose of ejecting the protective sleeve,

Fig. 3 shows the upper part of the case in position the spreading of the protective sleeve, just before the segments forming it fall off, and

F i g. 4 shows the section along the line IV-IV of FIG. 1.

The in the F i g. 1 and 2 shown case for a pen made of a paste material consists essentially from two coaxial, cylindrical sleeves 1 and 2, one in the inner sleeve J, cylindrical cup 3, which carries a lipstick 4, and a protective sleeve 5 for said stick.

The sleeve 1 lies within the sleeve 2 and can be rotated with respect to it. The relative axial position these two sleeves are held in place by the fact that the ends of the outer sleeve 2 on two shoulders 6 or 7 of the inner sleeve 1 rest. In addition, the shoulder 7 is in the form of a maneuvering head 8, with the help of which the two sleeves can be rotated against each other with slight friction.
