Description

Beiersdorf AG

Use container for pens, for example Lippeπstiftbehälter

The invention relates to use containers for stick-shaped materials, in particular highlighters, wax crayons, lipsticks, wherein the use containers are open at one end side and closed at the other, with a holder for the pin axially displaceable inside the container housing along guides, a flexible operating band, which is set in the middle under the bottom of the socket and with its free end to the

Closing the front-side container opening is used, wherein in the interior of the container housing are provided on the open container end and from the open container front side to the closed container end guides and in the region of the closed Behälterstimseite a deflection guide for the operating band and the operating band of the container outside accessible actuator frictionally or positively is engaged, whereby the rotational movement of the actuating element is converted into a translational movement of the displaceable socket.

In the known such use containers for cosmetic pencils, such as lipstick containers has, starting from the mounted inside the container guides for the operating band, the outer shape of the container angular, usually sharp rectangular or square formed (see Fig. FR-PS 750469 and 1 003693) , Due to their angular outer shape, such lipstick containers are uncomfortable and annoying in use. In addition, the operation of the closure and the operation of the pin-carrying version is often unreliable and often unsatisfactory. Finally, the known lipstick containers also have disadvantages in terms of manufacture and assembly.

In DE-OS 2261 892 utility containers are shown for cosmetic pens, which are improved with respect to the production and ergonomics over the above.

From DE-OS 32 11 065 a rotary sliding pin is known, in which a rotational movement of a handle handle is reacted relative to the grip sleeve in a linear vertical displacement associated with the handle handle recording. There, the inner wall of the grip sleeve on the classic helical longitudinal groove. Before that still extends a rotatable inner sleeve. The latter has axially parallel longitudinal slots. The are penetrated by radially projecting sliding blocks of the recording, with the sliding blocks penetrate into the helical track of said longitudinal grooves. This is the result of the rotatable Handle handle exercisable height displacement of the usually rod-shaped consumable. This solution is relatively expensive to manufacture.

DE-OS 19828 240 rotary-slide pins, especially for cosmetic purposes, with a guided in a grip sleeve recording the consumable pen and a

Rotary drive for displacing the consumable pen known, the rotary drive has a transverse to the displacement shaft lying wave and achieved by windable on the shaft tensile and pressure-resistant members as a connection between the shaft and recording a structurally simple, reliable solution.

From DE-GM 80 18 892 a rotary sliding pin is apparent, the actuating mechanism consists of a kind of rack and pinion. The there designed as a pressure floor recording of the consumable pen is moved by a rotary drive, which has a transverse direction to the displacement shaft, which is designed as engaging the rack wheel whose freely protruding from the housing peripheral portion presents itself as a knurled actuating surface. Such a rack and pinion drive requires a large height to accommodate the rack.

In contrast, the present invention seeks to provide utility containers for pens that can be easily manufactured and assembled from a few items that also ensure reliable closure and reliable, trouble-free operation of the pin-carrying socket. Last but not least, the use of containers are also to be improved in terms of their external shape to the effect that a comfortable use, in particular a retraction or retraction of the pin from the container during use is possible, as in particular in the one-handed use of

Lipsticks and highlighter is required to apply the dye with gentle rotation of the pen and its container can.

This object is achieved according to the invention in that the container housing is formed with modified rectangular outer shape, wherein the container housing consists of at least a first and a second housing part and inside the housing at least one guideway between the two substantially planar wall parts, the upper and lower housing part, a second pair of central axial guideways and at least one deflection guide is formed in the meeting area of the guideways and the container bottom.

The transport of the operating band, and thus the movement of the pin, is solved such that a drive combination between an actuating element, a drive wheel and I formed the operating band, which converts the rotational movement of the actuating element in a translational movement. This conversion can take place both form-fittingly via suitable engagement elements or frictionally via suitable material pairings or surface structures. Suitable engagement elements on the actuating element are z. B. teeth of a pinion, in a regularly arranged breakthroughs in the operating band, similar to a link chain, immerse.

Drive wheel and actuator can be connected to each other and sit on an axle. Likewise, it is possible to arrange the drive wheel and actuator on two separate axes, in which case the actuating element is designed so that it can engage with a part of its surface in the drive wheel and drive it.

In order to achieve a minimization of the height of the pin, it is advantageous that the arrangement of the drive wheel is selected in approximately the center of the pin.

The actuator protrudes according to the invention only with a part of its circumference from the outer surface of the housing.

The number of openings in the operating band is advantageously to be chosen so that halfway through the pushing out of the product chamber, the openings overlap the drive wheel and thus a double engagement is granted to the front and rear of the drive wheel. For this it is necessary that the deflection of the operating band is not chosen wider than the pitch circle diameter of the drive wheel. This will be moved from front to back on further pushing out the Käfteinleitungspunkt on the pinion. When retracting the force application point is moved back.

In the context of the invention, the socket and the operating band are molded from flexible plastic, wherein mold release agent is added to the plastic. As a result, the socket and the band have an exceptionally smooth, lubricious surface. As a result, the friction is largely reduced and the operation largely facilitates the advancement of the version.

The applied by the user force or the number of revolutions of the actuator can be changed by a transmission gear, the translation depends on the circumference of the drive wheel to the circumference of acting on the drive wheel surface of the actuating element. In this case, the actuating element can alternatively also be designed as a displaceable rack. When using a gear, the handwheel can be moved further to the opening of the container housing.

The invention provides a novel, improved container for pens, in particular cosmetic pens, which is to be actuated with the fingers of a mand. Due to its round edges, the container can be easily and safely twisted or turned over when applying cosmetic substances or writing in the hand. The housing parts can be easily and inexpensively manufactured in simple forms of plastic and assemble easily and inexpensively, whereby a minimum amount of manufacturing costs is achieved. When the container is closed, it can be easily secured in this closed position, so that damage to the pin is effectively prevented.

For assembling the utility container, the operating band is inserted with the pin socket and plugged actuator simultaneously with the insertion of the second housing part in the first housing part and securely fixed there.

In the context of the invention, a housing part with a projection and the other may be formed with a corresponding receptacle. This arrangement facilitates the manufacture of the utility container, in particular its assembly.

The operating band may be formed in the invention with one or more protruding ribs or nubs, which cooperate with ribs, nubs or other projections in the housing to increase the reliability of the closure and thereby protect the pin contained in the container against damage. The nubs form a resilient stop by which the socket is resiliently held in the retracted position while the operating band is resiliently held in the extended position in which its free end occupies the circular upper container opening. In this way, only a deliberate opening makes it possible to bring the socket into its advanced position, in which it can partially protrude from the upper part of the housing. The cooperating studs form an integral part of the invention in that they provide a reliable closure for the housing and prevent damage to the product pin carried by the socket.

The strip-guiding grooves can be formed in the invention with non-uniform width, whereby mutual interference between the socket and its contents and the sliding and tension band are excluded. Finally, the material of the socket and the operating band demolding substances can be added to these parts with form a particularly smooth, lubricious surface and so facilitate a smooth advancement and retraction of the socket by applying force to the band.

Further features and advantages of the invention lie in easy operation of the container when applying a cosmetic product or when writing and a slight renewal of the pin when the previous one is consumed.

Further features and advantages of the invention will become apparent from the following description of two embodiments with reference to the drawing. However, the invention should not be limited to the embodiment, which serves only to visually support the description.

(Figures 1 to 5, the illustrated use container 100 includes a two-part housing with a lower housing part 110 and an upper housing part 120. The housing parts 110 and 120 are molded from plastic, preferably injection molded and by cement (adhesive), hot-sealing, ultrasonic welding or the like connected to each other.

According to the invention, the housing handles 110 and 120 together form a modified parallelepiped-shaped outer surface, with a rear side 103 of a front side 105, two side walls 104 and 106, the side wall 106 being closer to the actuating element 150 than the side wall 104 and a top side 109 and a bottom side, well rounded corner edges 101 and 102, at the edges formed by the back and sidewalls, allow the utility bin to be conveniently and easily turned around in the hand by the user, which is important for applying lipstick or writing. In the front side 105 is a slot-like opening 111, from which the inner actuating element 150 emerges with a part of its circumference.

The rounded design makes the turning movement of the use container in the hand easily possible, while square or other square cross-sectional shapes even with rounded corner edges cause difficulties in exporting such Umdrehbewegungen.

By special design of the advancing and retracting of the supported by the Gleitfassung 141 pin enabling actuators 150 in conjunction with the above-described outer shape of the container, a comfortable use when applying the product can be achieved. The upper housing part 120 has in its top surface 109 forming part of the opening 122 to which at the edge 123 at an obtuse angle, the surface 105 a is hinged, which forms a part of the front side 105 in the assembled state. Below the opening extends into the interior of the utility container, a half-cylinder 121 which extends in the assembled state almost to the bottom of the use container and a deflection of the actuating band 140 at its lower end, a guide of the socket 141 on its side facing the interior and a Guiding the actuating strip 140 causes on its inside the front side 105 facing side, wherein the front side 105 facing outer side 128 of the half-cylinder is designed flattened and forms a plane-parallel gap with the inside of the front side 105.

As in the figures. 2, 4 and 5, guide mechanisms for the operating band 140 and the socket 141 are formed by the upper casing half 120 and the lower casing half 110, mainly the grooves 107 and 108, the guide webs 112 and the parallel gap formed to the longitudinal axis of the use container between half cylinder 121 and inside of front side 105. The grooves have direction-diverting portions at their bottom ends.

FIG. 5 shows the individual parts of the utility container from FIG. 1, comprising a molded unit of holder 141 and actuating band 140, the latter being attached to the bottom wall of the holder 141 along a diametrical line. The operating band 140 has opposite guide ribs 143 and 144, wherein the guide rib 144 is formed widened and parallel to the edge a number of apertures 145 for engagement of the Artriebsrades 151 receives.

The guide grooves 107 and 108 are formed by the lands 107b and 108b of the lower shell half 110 and the lands 107a and 108a by a projection of the edge of the half-cylinder 121 of the upper shell half 120 (see Figures 4 and 5).

If the socket 141 is in the retracted position, the opening 122 in the upper housing half 120 is closed by the free end 142 of the actuating band, wherein a deflection takes place in the region of the inside of the edge 123.

The lower half of the housing has a slot 111 for receiving the actuating element 150, which is integrally connected to the drive wheel 151 and mounted on the axis 124 of the upper half of the housing, wherein the axis 124 emerges perpendicular from the surface of the half-cylinder 121. Accordingly, a rotational movement exerted on the actuating element 150 about the axis 124 is transmitted via the drive wheel 151 into a translatory movement of the actuating belt 140.

When the band 140 is in the raised position, its upper portion seals the opening 122 of the housing and the socket 141 is in the retracted position. Moving the band 140 in its retracted position, the opening 122 is revealed, and the socket 141 may protrude from the opening.

In the context of the invention, the grooves 107 and 108 of the lower and upper housing halves 110 and 120 have graduated width, i. H. Sections of varying width. They are, for example, in the area of the deflecting guide 126 and 127 further and formed narrower at a distance from these deflecting guides. As a result, the tape is prevented from seizing as it moves away from the deflection guides 126 and 127.

In FIGS. 6 and 7, a pen container according to the invention is shown which, in contrast to the use container in FIG. 1, has a two-part drive, wherein the actuating element 250 and drive wheel 251 are seated on two shafts 224 and 225 emerging from the half cylinder 221. This results in a displacement of the actuating wheel in the direction of the top 209 result. Accordingly, the opening for the actuating element 211 in the front side 210 also extends to the upper housing half 220.

All in the description, the claims and the drawing reproduced features may be alone or in any conceivable combination of essential importance to the invention.
