Abstract

The application pen (1) has an application body (2) which is held on a bracket (14). A sliding projection (19) having a lever arm projects downward in relation to a base of holder, which is connected with the bracket and projects outside in pushing through a longitudinal slot (13) of a casing (3). A braking device, formed at a carrier, is activated by the sliding projection, which remains in friction or form fitting manner at inner surface (11') of the casing. The lever arm is in opposite position to the vertically extending carrier.

Description

The invention relates to an application pen such as lipstick or glue stick with an application mass, wherein the application mass is accommodated on the foot on a support base having a bracket and is slidable in a sleeve having at least one longitudinal slot, further at least one, with respect to the support bottom down protruding lever arm having sliding projection is formed, which is connected to the holder and projecting under the enforcement of the longitudinal slot to the outside, being acted by means of the sliding projection formed on a carrier brake means which is in frictional and / or positive connection to the inner surface of the sleeve.

Application pens have long been known from the prior art and are available in different embodiments on the market. For example, as a lipstick, glue stick, crayon or the like. The application pins have in common that they each have an abrasive application compound, which can be applied, for example, by a slide displaceable vertically in the application pen. A generic application pen, in particular lipstick, is for example in the US 3,708,236 disclosed. There, it is provided that the cylinder-like application pin having a circular cross-section has a covering cap which, in a customary manner, protects the application compound stored in the application pen in a non-use position. In addition, the inner wall of the plugged-in on the application cap cap presses in the non-use position two diametrically opposite, guided in vertical longitudinal slots and each forming a lever arm slide projections facing each other pen inward. These sliding projections are connected within the application pin with a vertically executable holder, which holder forms a carrier for the application mass. Due to the plugged cap is integrally formed on the Schiebevorsprüngen and arranged on the carrier brake means brought out of braking engagement. As soon as the cover cap is pulled off the application pin, the slit-guided and lever-like sliding projections automatically pivot outward, so that the brake means is in braking engagement with an inner wall of the pin. For vertical displacement of the application mass, the slit-guided slide projections must again be pushed inward towards the pen, for example via the thumb and forefinger of an operating hand, in order to bring the brake means out of engagement. Then the application compound can be extended or retracted vertically via the slide projections. If no pressure is exerted on the sliding projections, the brake means again comes into braking engagement. By the frictionally cooperating with the inner wall of the pin braking means of the contact pressure when applying the application mass is decelerated to prevent uncontrolled, undesirable retraction of the application mass.

Also braking means are known, the locking, so form-fitting, with the inner wall of an application pen such as. Lipstick, crayon or the like cooperate.

The invention has the object of advantageously developing an application pen such as lipstick or glue stick.

This object is achieved first and foremost in an application pen having the features of claim 1, wherein it is provided that the lever arm is in opposition to the vertically extending support, which is to bend to cancel the braking effect on a longitudinal axis of the application pin , The opposing position of the lever arm and the carrier leads to an allocation-favorable loading of the carrier by the lever arm. The lever arm is moved directly to the carrier to move it to the release position. Here, the carrier of (radially) outside bent (radially) inside the pin. Thus, it can be provided that the lever arm is positioned to the carrier with a not appreciable distance, so that upon radial inward displacement of the sliding projection and, consequently, the lever arm is acted upon directly on the carrier. In principle, the opposing layer can also be constructed with a direct connection of lever arm and carrier. In a preferred embodiment it is provided that the lever arm to the carrier in the non-operative position, ie in the braking position, a spaced opposite overlay. This distance measurement, which lies in the range of a few millimeters, serves as a noticeable freewheel when the push projection is actuated by pressure. A lifting of the braking action is given after overcoming the freewheel, wherein the required pressure force to cancel the braking action can be made small. The contact force of the braking means acting on the inner surface of the preferably cylinder-like application pin is dimensioned sufficiently large with regard to a frictional engagement, so that the application mass, due to the bearing force arising during application, does not automatically migrate into the pin. Preferably, for intentional cancellation of the braking action of the lever arm having sliding projection, for example by means of thumb pressure radially inwardly toward the longitudinal axis of the application pin before a vertical displacement movable. The vertical displacement of the slide projection entails a vertical displacement of the application mass, which displacement is directed outward or inwardly, depending on the application state.

The subjects of the further claims are explained below to the subject of claim 1, but may also be significant in their independent formulation.

Thus, it proves to be advantageous for the lever arm to extend freely overlapping the carrier, preferably in symmetrical overlap with one another. The lever arm can have a longitudinal extent, which is something is dimensioned larger than the longitudinal extent of the carrier. For the necessary articulation of the lever arm is provided, that the lever arm is connected above the mounting base with the holder, so that the lever arm has a pivot point which is vertically spaced from the mounting base.

In order for the application mass received by the holder and preferably having a circular cross-section to be firmly seated in the holder at the foot, it is proposed that the holder has a circular cylindrical wall extending from the holder base, ie in the dispensing direction, which in turn together with the holder base forms a recording pot surrounding the longitudinal axis of the application pin for the application mass.

To achieve a favorable design, it is proposed that the carrier having the brake means is formed in alignment with the cylinder wall on the mounting base. This means that the outer wall of the carrier is flush with the lateral surface of the cylinder wall. With respect to the longitudinal axis of the applicator pin, the cylinder wall and the carrier extend in opposite directions, i. the cylinder wall extends in the dispensing direction from the holder base, the carrier in turn against the dispensing direction. It is also advantageous that the carrier has a physical shape, which is formed like a tongue. This shape gives the carrier in the Hebelarmbeaufschlagung the necessary flexibility, wherein the carrier has a cross section which is preferably adapted to the cross section of the cylinder wall. As a result, the tongue-like carrier is formed as a circular ring section. The width dimension of the carrier is preferably dimensioned larger than the width dimension or the thickness direction of the lever arm, preferably with a ratio of 3: 1.

The sleeve forming the core region of the application pen and surrounding the application mass is preferably stepped in the vertical direction.

As a result, the sleeve has a larger diameter base and a smaller diameter upper section. The aspect ratio of socket to top section is about 1: 3. By the foot of the application pen forming diameter larger sized socket the application pin is sufficiently detectable during use. In addition, a sufficiently large footprint is created by the base, which ultimately serves for a better stability of the application pin.

Further, the invention proposes that the sliding projection vertically leading longitudinal slot is formed in the smaller diameter upper portion of the sleeve. Due to the different sized diameter of the base and upper portion of the upper portion is surrounded at its root portion of an end face of the base. This end face is also an end stop and limits the rearward displacement of the sliding projection. The sliding projection lies with its pointing to the base end in the basic position on the base end face. In an advantageous embodiment of the invention, it is provided that in the transition from the base to the upper portion, an end face of the socket passing through opening is formed, which corresponds in its extension at least the width of the extension outside of the sleeve vertically displaceable sliding projection. The opening, which is preferably adapted to the width dimension of the sliding projection, advantageously serves as a mounting opening or insertion opening for the sliding projection. The holder, the lever arm having sliding projection and the brake means having carrier and the braking means themselves are also preferably formed integrally with each other. Accordingly, a one-piece mounting member is formed in a simple manner, which optionally together with the application mass for mounting from the bottom of the preferably hollow socket in the sleeve can be inserted, wherein the longitudinal slot upstream socket opening serves as an insertion opening for the sliding projection. While the sliding projection is positioned outside the sleeve in the assembled state, it preferably penetrates the sleeve Back of the sliding projection integrally formed lever arm with its preferably integrally formed on the cylinder wall of the bracket, transversely aligned to the longitudinal axis of the application point pivot points the longitudinal slot, which in turn has a width dimension that is dimensioned slightly larger than the width dimension of the pivot point to allow a secure vertical guidance.

The cooperating with the inner wall and integrally formed on the carrier braking means preferably consists of two arranged on a horizontal plane projecting hemispheres which are positioned in the mounted state of the application pin on both sides of the longitudinal slot. Also, the braking means may be formed rib-like, which ribs may extend both vertically and horizontally aligned on the carrier.

To protect the application mass or disuse, a cap is provided, which not only protects the application compound in the closed state, but also completely overlaps the sliding projection. The sliding projection does not interact with the cap, but is overlapped by this. For putting on the cap, the application mass possibly protruding from the application pen is to be moved inwards over the sliding projection. So that the user can easily remove the covering cap from the application pen, it is preferably provided that the covering cap has, in its longitudinal wall, an opening which is open towards its lower edge. About this opening the base of the pen is easily detected, for example, over the thumb, so that the arranged on the pin, preferably latch-connected cap is peelable in a known manner. It can also be provided that the cover has two preferably diametrically opposite apertures arranged over which the socket for the user can be detected improved.

Preferably, two diametrically opposed longitudinal slots are also provided, in which two diametrically opposite arranged on the Holder molded sliding projections are performed. With two slide projections, it is even easier to output the application compound. Tilting the pen is less likely. In addition to the second slide projection, a further second carrier having a brake means can also be arranged on the holder in accordance with the configuration of the carrier described above. Also, the second slide projection may be formed integrally with the holder.

With reference to FIGS. 1 and 2, an application pen 1 for applying an application mass 2 is shown and described. With regard to the composition of the application mass 2, the administration pen 1 can be used, for example, as a lipstick, glue stick or, moreover, as a wax crayon or chalk pen. In addition, the application compound can be a care product for items such as clothing, upholstery for the automotive sector or wood products. Also, the application pen can serve as a food dispenser, such as for use as a lollipop.

In essence, the application pen 1 consists of a core portion forming a cylindrical shaped sleeve 3 and the sleeve 3 cross-cap 4, which in turn, as shown in Fig. 2, the base side with the preferably circular cross section having a sleeve 3 is latchably connected. For this purpose, the stepped sleeve 3 has a circular cross-section having base 5, the foot side a circumferential annular bead 6 is formed, which interacts with plugged-cap 4 with a foot on this arranged and from the inner wall of the cap 4 correspondingly formed annular groove 7 latching. For centering the approximately cylindrically shaped and tapered plugged covering cap 4 is provided that these arranged on the inside, spaced-apart vertical ribs 8, which originate on the underside of a cover 9 of the cap 4. As can be seen in FIG. 2, the vertical ribs 8, which are approximately stepped in cross-section, interact with a cap collar 10 integrally formed on an upper section 11 of the sleeve 3, with the cap 4 attached.

The annular collar 10 flanking an output opening 12 of the upper section 11 and surrounding the longitudinal axis x of the application pen 1 is associated with the free end of the upper section 11 relative to the representations.

As can be seen, the base 5 and the vertically protruding from the base 5 upper portion 11 are formed with different outer diameters, wherein the base 5 has the larger diameter and the upper portion 11 has the smaller diameter outer diameter. In addition, the base 5 has a shorter dimensioned longitudinal extension than the upper portion 11, wherein in this embodiment the length ratio between the base 5 and the upper portion 11 is approximately 1: 3.

It is further provided that the sleeve 3 at its upper portion 11 has two diametrically opposed, vertically extending longitudinal slots 13 for guiding a holder 14 for the application mass 2, wherein in each case the longitudinal slots 13 terminate below the annular collar 10 via their slot ends 15. The other opposing, open slot ends of the longitudinal slots 13 each open into a socket 5 passing through, diametrically opposed through opening 16. These axially parallel to the longitudinal axis x extending through openings 16 are each from the, based on the representations, upwardly facing end face 17th the base 5 is formed.

Provided for the application mass 2, within the upper portion 11 of the sleeve 3 vertically displaceable holder 14 is shown in Figures 8 -10 each in an enlarged single view. For receiving the application mass 2, the holder 14 is formed as a cylinder wall 14 'having a pot with a circular cross section, wherein the application mass 2 foot side on a cylinder wall 14' surrounding support base 18 of the holder 14 is seated end face. To guide the holder 14 within the upper portion 11 is provided that the cylinder wall 14 'of the holder 14 has an outer diameter D ₁ , which is dimensioned slightly smaller than the inner diameter d _{1 of} the upper portion 11. As a result, the holder 14 is within the upper Section 11 smoothly vertically displaceable. As can be seen, the outer diameter D _{2 of} the application mass 2 is adapted to the outer diameter D _{1 of} the cylinder wall 14 ', so that with respect to the inner diameter d _{1 of} the upper portion 11, the application mass 2 within the upper portion 11 is movable without contact vertically. The inner diameter d _{2 of} the pot-shaped cylinder wall 14 'is smaller, the outer surface of the application mass is aligned above the cylinder wall 14' with its outer surfaces.

The holder 14 has two diametrically opposed, shield-shaped and in the direction of the longitudinal axis x extending sliding projections 19, via which the holder 14 is vertically displaceable on the pin 1. The respective one arcuate cross-section having sliding projections 19 are the longitudinal slots 13 upstream and surrounding the outer surface of the upper portion 11. Each having an externally molded, slip-resistant ribbing sliding projections 19 each have at their back a molded elongate lever arm 20, which in turn via articulation 21st on the outside of the cylinder wall 14 'of the holder 14 transversely to the longitudinal axis x are formed aligned. As a result, the oppositely arranged sliding projections 19 are fixedly connected to the holder 14. As shown in FIG. 13, the articulation points 21 in each case pass through the longitudinal slots 13 in each case for guiding the entire holder 14, wherein the width dimension of the articulation points 21 is adapted in each case to the opening width of the longitudinal slots 13.

It is further provided that the holder 14 facing away from the support base 18 and integrally formed on this tongue-like, diametrically opposed, circular arc-shaped carrier 22 has, which are each outside the outer diameter D _{1 of} the cylinder wall 14 'adapted. The carrier 22, which extends vertically downward relative to the illustrations on the mount 14, each have braking means 23 formed on their outer wall in the form of raised hemispheres. These projecting from the carriers 22 transverse to the longitudinal axis x aligned braking means 23 respectively point in the direction of the back of the sliding projections 19 and flank, as shown in Fig. 10, respectively, the lever arm 20 of the sliding projection 19. It is further provided that the braking means 23 with Distance to the, based on the representations facing down, free ends of the carrier 22 are formed on these. As a result, the braking means 23 have a vertical distance to the support bottom 18, which in this embodiment corresponds to more than twice the thickness of the support floor.

The support provided as a whole with the reference numeral 14 comprises the sliding projections 19, the lever arms 20, the articulation points 21, the carriers 22 and the brake means 23. These parts are integrally formed with one another.

For mounting the holder 14, this clip-like over the bottom open base 5 to the interior of the upper portion 11 via the insertion openings 16 are fed, each having the insertion openings 16 have a width dimension, which is dimensioned slightly larger than the width dimension of the sliding projections 19. For insertion of the Holder 14, the sliding projections 19 are facing each other slightly compressed. If the vertical insertion of the holder 14 takes place, in each case after passing through the insertion openings 16, the articulation points 21 of the lever arms 20 enter into the longitudinal slots 13. Once the holder 14 is fixed to the upper portion 11, so that the sliding projections 19 have each penetrated the push-through openings 16, the sliding projections 19 snap over the push-through openings 16 radially outward as shown in Fig. 13. This is an intrinsic safety of the holder 14 on the Pin given, in each case the downwardly projecting end faces 24 of the sliding projections 19 rest on the end face 17 of the base 5 in the retracted basic position. As can be seen in FIG. 13, the brake means 23 of the carriers 22 positioned on both sides of the longitudinal slots 13 act on the inner wall 11 'of the upper section 11 so that the holder 14 and thus also the application mass 2 frictionally engage within the application pin 1 against vertical displacement is slowed down.

After removing the cap 4, the application pen 1 is exposed. If an output or an application of the application compound 2 is desired, the user can, for example, with the thumb and the index finger, the two Grasp sliding projections 19 and squeeze lightly. Here, the integrally formed on the back of the sliding projections 19 lever arms 20 radially inwardly, the longitudinal slots 13 passing through, in the direction of the carrier 22 until the lever arms 20 act on the carrier 22 between the braking means 23 and thus bend them radially inwardly. In this case, the braking action of the brake means 23 on the inner wall 11 'is canceled, so that the holder 14 and the application mass 2 via the slide projections 19 is vertically displaceable. This vertical displacement of the holder 14 is stop limited such that in each case the slot ends 15 of the longitudinal slots 13 upwards, ie maximum extension position of the application mass, form end stops. In the retracted basic position, the holder 14 is also stop-limited by the interaction of the end faces 24 of the sliding projections 19 and the end face 17 of the base 7.

For better handling of the application pen 1, it is provided that the cap 4 at its lower peripheral edge 25 radially in the longitudinal wall 26 preferably diametrically opposite perforations 27 has, so that on these window-like openings 27 for removing the cap 4 of the application pen 1 respectively the base 5 can be detected in a simple manner.

All disclosed features are essential to the invention. The disclosure of the associated / attached priority documents (copy of the prior application) is hereby also incorporated in full in the disclosure of the application, also for the purpose of including features of these documents in claims of the present application.
