Definitions

  • the invention relates to a cosmetic pencil holder with a cosmetic pencil mechanism, which has a piston for carrying the cosmetic pencil, a slotted sleeve in which the piston is displaceable and which is provided with a longitudinal slot, and a screw sleeve in which a thread is formed and the slotted sleeve is rotatable is recorded, a pin on the piston protruding through the longitudinal slot of the slot sleeve into the thread of the screw sleeve and the slot sleeve protruding with a foot part from the screw sleeve, and an outer cap part in which the cosmetic pen mechanism is held with the foot part of its slot sleeve and from which the screw sleeve in turn protrudes such that the piston in the slit sleeve by rotating the screw sleeve relative to the outer cap part in one direction of rotation towards the end of the slit sleeve facing away from the foot part up to a first end position and back in the other direction
  • the cosmetic stick which can be supported with its foot on the piston, which can be a lipstick, a deodorant stick or the like, is moved out of the open end of the slotted sleeve or back into the slotted sleeve drove in.
  • the outer cap part serves as the lower part of a protective cover, which is usually designed as a decorative cover.
  • a central connecting piece can be formed on the bottom thereof, which engages relatively firmly in a central hole in the foot part.
  • the invention solves the problem of designing a cosmetic pencil holder of the type mentioned in the preamble of claim 1 in such a way that the reusability of the outer cap parts is ensured, which not only benefits environmental protection by reducing waste, but also the design of the outer cap parts as more or less allows valuable jewelry.
  • the cosmetic pen mechanism is held interchangeably in the outer cap part by means of a releasable closure which has two closure parts which are formed on the outer cap part on the one hand and on the foot part of the slotted sleeve on the other hand and which at least axially hold together the outer cap part and the foot part and which by Relative rotation of the outer cap part on the one hand and the foot part by means of the screw sleeve on the other hand can be detached from one another with the piston held in one of its end positions.
  • the resistance to the relative rotation to release the closure must be greater than the resistance to the rotation of the screw sleeve relative to the outer cap part for the retraction or extension of the cosmetic stick from the slotted sleeve, so that the closure is not inadvertently released.
  • the piston in its two end positions is preferably held at a stop against further displacement, the screw sleeve is locked in one direction of rotation by the cosmetic pin mechanism via the pins of the piston, so that in this direction of rotation the relative rotation for releasing the closure also against a larger one Resistance can take place.
  • the direction of rotation for the relative rotation of the screw sleeve relative to the outer cap part for releasing the closure corresponds to that of the Screw sleeve coincides, in which the cosmetic pen is inserted into the slotted sleeve, so that the closure can be released when the piston is in its lower end position.
  • one closure part is a radial projection and the other closure part is an axial shoulder as a seat for the radial projection, which can and is locked and unlocked axially by relative rotation of the outer cap part on the one hand and the foot part by means of the screw sleeve on the other hand with the piston held in one of its end positions on the axial shoulder formed axially between the two components formed by the foot part and the outer cap part on one of these a spring part axially pushing the components apart.
  • a bayonet-type locking device is provided between the outer cap part and the foot part of the cosmetic pen mechanism, the radial projection and the axial shoulder being able to be held sufficiently firmly under the force of the spring part that the screw sleeve is relative for the use of the cosmetic pen can be rotated to the outer cap part and thus to the slotted sleeve without unintentionally releasing the lock by turning back the foot part.
  • the axial shoulder faces away from the cap bottom of the outer cap part and is overlapped by the radial projection. Conversely, if the radial projection is formed on the foot part and the axial shoulder is formed on the outer cap part, the axial shoulder faces the cap base and is gripped by the radial projection.
  • the radial projection can be designed as an axially extending rib, its design as a pin, in particular as a round pin, is preferred.
  • the spring part can for example be designed as a resilient bulge of the bottom of the outer cap part or the foot part of the slotted sleeve. It is also possible to form one or more projections on the inside of the bottom of the outer cap part and to provide the spring part as a resilient bottom of the foot part. This possibility is particularly suitable if the outer cap part is deep-drawn from metal and the projections are formed on the cap base by pressing, whereas the base part made of plastic is bulged out resiliently by the projections.
  • the spring part is designed as a resiliently flexible tab formed on the one component with an eccentrically arranged to the axis of rotation of the screw sleeve, preferably designed as a rounded knob, which engages in the locking state of the radial projection in a complementary recess of the other component.
  • an additional rotation lock of the foot part is achieved, whereby the spring part can be designed for a lower spring force.
  • This possibility of forming the spring part is preferred when the outer cap part is formed from plastic material.
  • the mutually engaging surfaces of the radial projection and the axial shoulder can be flat if the frictional force acting between them in the locking position is sufficient to prevent them from unintentionally turning apart when the screw sleeve is turned, or the foot part is used by other measures, such as the rotation lock specified above the spring tab, is prevented from rotating with the screw sleeve during its normal operation.
  • Such, and also preferred measure is the formation of the axial shoulder as a locking trough, and the radial projection as a round pin, so that here too there is a certain positive locking against rotation of the foot part in the locking position. However, this positive engagement can be overcome for an intentional unlocking of the foot part due to the resilience of the spring formation.
  • the component having the axial shoulder has a guide groove opening on one side of the axial shoulder for the radial projection designed as a round pin, which is axially open at the end facing away from the axial shoulder and from which the round pin extends until it engages the axial shoulder can be turned out.
  • a guide groove opening on one side of the axial shoulder for the radial projection designed as a round pin, which is axially open at the end facing away from the axial shoulder and from which the round pin extends until it engages the axial shoulder can be turned out.
  • the guide groove can extend axially
  • the guide groove preferably runs obliquely to the axial direction, so that the circular pin is screwed into the outer cap part when the cosmetic pin mechanism is inserted, preferably in such a way that the foot part in the outer cap part has the same direction of rotation as the direction of relative rotation for the axial locking of the radial projection can be screwed onto the axial shoulder.
  • a second guide groove for the round pin opens, which is axially open at the end facing away from the axial shoulder and into which the round pin can be rotated out of engagement with the axial shoulder, in particular being preferred, to form the second guide groove on that side of the axial shoulder which is opposite to the direction of rotation of the screw sleeve when the piston is moved back towards the foot part.
  • the second guide groove may also run obliquely to the axial direction or may have another course deviating from the axial direction, it preferably runs parallel to the axial direction, so that the cosmetic pencil mechanism axially after unlocking from the Outer cap part can be pulled out.
  • Such a measure favors the ability to provide two locking devices according to the invention, diametrically opposite the cosmetic pencil holder, without design restrictions.
  • the closure can also be designed as an axial plug-in connection, in which one of the components formed by the foot part and the outer cap part has a central opening and the other component has at least one axial projection which is rotatably inserted into the central opening and which on the edge of the Central opening attacks, on the circumference of one of the components an inclined shoulder and on the other component a slidably engaging counterpart on the inclined shoulder are formed, which slide against each other during the relative rotation for releasing the closure parts and axially push the foot part and the outer cap part apart by releasing the plug connection .
  • the plugging together of the Cosmetic pencil mechanism and the outer cap part in the axial direction which can usually be achieved without great effort.
  • the inclined shoulder and its counterpart enable the plug connection to be released more easily by a rotary movement of the cosmetic pencil mechanism relative to the outer cap part, by means of which these are virtually screwed apart .
  • the inclined shoulder and its counterpart also prevent the foot part of the cosmetic pencil mechanism from rotating in the outer cap part.
  • the axial projection and the central opening can engage in a non-positive manner in the closed position.
  • a plurality of axial projections in the form of spring tabs arranged in a circle with external latching projections can be provided at their free ends, which can engage behind the edge of the central opening.
  • a cup-shaped piston 1 which carries the cosmetic stick (not shown), can be displaced in a slotted sleeve 2, which in turn is rotatably received in a screw sleeve 5.
  • the slit sleeve 2 has two diametrically opposite longitudinal slots 4.
  • the piston 1 has on its outer wall two diametrically opposed, radially projecting pins 7 which protrude through the longitudinal slots 4 of the slot sleeve 2 into the respectively assigned thread 6 of the screw sleeve 5.
  • the pin 7 are moved when rotating the screw sleeve 5 around the slotted sleeve 2 on the trailing edge of the threads 6 in the associated longitudinal slot 4, whereby the piston 1 is axially displaced in the slotted sleeve 2 and therefore the cosmetic stick from the open end of the Slotted sleeve 2 is withdrawn or retracted into slotted sleeve 2.
  • the slotted sleeve 2 with a cup-shaped foot part 3 with a central opening 19 in the bottom part 17 extends beyond the screw sleeve 5, as a result of which the slotted sleeve relative to the screw sleeve 5 by attacking it and against it the foot part 3 can be rotated.
  • the outer diameter of the foot part 3 corresponds to that of the screw sleeve 5.
  • the lower section of the peripheral wall 24 of the foot part 3 is thickened on the inside.
  • the cosmetic pen mechanism is used with the foot part 3 of the slotted sleeve 2 and the lower part of the screw sleeve 5 in an outer cap part 8 in the exemplary embodiment (other shapes of the same are also possible), in which the screw sleeve is rotatable, but the foot part 3 is held axially and against rotation is.
  • two radial projections formed as round pins 9 are formed on the inner wall of the outer cap part 8 at a distance from the cap base 16 diametrically opposite to the outer cap part 8.
  • each of the round pins 9 is formed on the outer circumference of the foot part 3 in the circumferential wall 24 of a guide groove 14 extending obliquely to the axial direction, the lower groove end of which is axially open on the underside of the foot part bottom.
  • the guide groove 14 is closed over the thickened circumferential wall section of the foot part 3 on the radial bottom and above the thickened circumferential wall section a radial slot and opens out on one side of an axial shoulder 10, which is designed as a detent depression for the associated round pin 9 and the open end of the outer cap part 8 is axially facing.
  • On the other side of the axial shoulder 10 opens a second guide groove 15 which extends axially in the peripheral wall 24 of the foot part 3 and is also open on the underside thereof.
  • two resilient tabs 11 are formed in it, which have a rounded extension 12 which is arranged eccentrically to the cap axis and which projects on the inside of the cap base 16.
  • the lugs 12 are diametrically opposed to the outer cap part 3.
  • two diametrically opposed recesses 13 are formed in it, which cooperate with the lugs 12 for locking the base part 3 against rotation when the cosmetic pen mechanism is inserted into the outer cap part 8.
  • the outer cap part is an injection molded part made of plastic material.
  • two openings 18 are formed, each of which is axially aligned with one of the round pins 9, so that the underside of the round pins 9 can be shaped using rod-shaped tool slides during injection molding of the outer cap part.
  • the side contours of the resilient tabs 11 are also formed using the tool slides.
  • the foot part 3 is screwed into the outer cap part 8 in a direction that corresponds to the relative rotation of the screw sleeve 5 relative to the slotted sleeve 2 for the insertion of the piston 1 into the slotted sleeve 2.
  • the round pins 9 of the outer cap part 8 enter the open ends of the oblique guide grooves 14 and are displaced in the guide groove 14 when turning further until the round pins 9 snap into the trough of the axial shoulder 10. Under the spring force of the resilient tabs 11, the round pins 9 are held against further rotation in the trough of the axial shoulder 10.
  • the lugs 12 of the resilient tabs 11 are snapped into the associated recess 13.
  • the foot part 3 is held axially on the axial shoulder 10 and under the spring force of the resilient tabs 11 due to the trough shape of the axial shoulder 10 and the locking engagement of the lugs 12 of the resilient tabs 11 in the associated recesses 13 against rotation in the outer cap part 8.
  • the piston 1 can be moved by rotating the screw sleeve 5 with respect to the outer cap part 8 and thus the slotted sleeve 2 for extending and retracting the cosmetic stick in the slotted sleeve 2 without the locking of the foot part 3 in the outer cap part 8 being released.
  • two downwardly projecting spring tabs 20 are formed on the piston 1, which extend into the annular space 26 between the cylinder extension 25 and the upper portion of the peripheral wall 24 of the foot part 3 and on the radially outer side in each case are provided with a locking projection 21.
  • the spring tabs 20 engage with their locking projections 21 in the locking openings 22 formed above the axial shoulder 10 above the axial shoulder 10 when the cosmetic pen mechanism is not locked in the outer cap part 8.
  • the locking projections 21 end with their radial end faces radially at a distance from the outer circumferential surface of the foot part 3 and are therefore arranged recessed in the locking openings 22 as seen from the outside.
  • the locking projections 21 on the spring tabs 20 are pressed out of engagement with the locking openings 22 by the round pins 7, whereby the slotted sleeve 2 and the screw sleeve 5 can be rotated against each other after the cosmetic pin mechanism has been inserted.
  • an oblique shoulder can be formed on the radial projections 9 and / or on the locking projections 21 of the spring tabs 20, by means of which the pressing out of the locking projections 21 is promoted.
  • a pellet 23 can be formed over the locking opening 22, which is destroyed by the round pins 9 being screwed into the axial shoulder 10. This creates an originality note which shows that when the cuticle 23 is undamaged, the cosmetic stick in the cosmetic stick mechanism outside the outer cap part 8 is not used.
  • the cosmetic stick can be provided in a manner known per se with a protective cover 40, which detaches from the cosmetic stick after the piston 1 has been extended for the first time. It is additionally or alternatively also possible, as shown in broken lines in FIG. 3, to cover the open end of the cosmetic pencil mechanism with a detachable protective cover 41.
  • the foot part 3 is locked together in the outer cap part 8 by means of an axial plug connection.
  • the central opening 19 within the foot part 3 of the cosmetic pencil mechanism is surrounded by a cylinder neck 32 which projects inwards from the foot part bottom 17 and which forms an axial shoulder 33 with its free end face.
  • a plurality of axially arranged spring tabs 30 are formed, each of which has at its free ends a radially outwardly projecting, approximately knob-shaped radial projection 31, which on the upper side slopes away radially outwards is.
  • the arrangement of the spring tabs 30 is adapted to the diameter of the central opening 19 of the foot part 3 such that the spring tabs 30 are deflected radially inward when the cosmetic pin mechanism is inserted axially into the outer cap part 8 when the lower edge of the central opening is directed onto the inclined surfaces of the radial projections 31
  • Spring tabs 30 hits, and then traverse the central opening 19 until they engage with their radial projections 31 behind the axial shoulder 33 on the cylinder neck 32 and thereby axially lock the cosmetic pencil mechanism in the foot part.
  • the cosmetic pin mechanism is therefore rotated with the plug connection 31-36 locked relative to the outer cap part 8, the inclined shoulders 34, 35 slide onto one another and press the foot part 3 and the outer cap part 8 axially apart, as a result of which the radial projections 31 detach from the axial shoulder.
  • the cosmetic pen mechanism can then be pulled axially out of the outer cap part 8 without exertion.
