Definitions

  • the invention relates to a cosmetic pencil holder with a piston for carrying the cosmetic pencil, which is displaceable in a slotted sleeve, which is rotatable in a screw sleeve and has a longitudinal slot, through which a pin on the piston extends into a thread in the screw sleeve, whereby the slotted sleeve protrudes with a foot part from the screw sleeve, which is held in an outer cap part, from which in turn the screw sleeve protrudes, such that the piston in the slotted sleeve by rotating the screw sleeve relative to the outer cap part in one direction of rotation toward the end facing away from the foot part the slotted sleeve, and in the other direction of rotation can be shifted back to the base part in an initial position, and wherein the slotted sleeve is locked with its foot part in the outer cap part by means of an easily releasable closure.
  • a holder is known from GB-A-8
  • the cosmetic stick which can be supported with its foot on the cup-shaped piston, for example, 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 inserted the slotted sleeve.
  • 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 cosmetic pen mechanism is manufactured and sold unchanged as an exchange group so that the outer cap parts are reusable, the cosmetic pen can also be removed from the slotted sleeve by rotating the screw sleeve relative to the foot part protruding therefrom, so that for the buyer in a number of cases there is no guarantee that the cosmetic pen purchased will not be used.
  • 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 cosmetic pencil mechanism outside of the outer cap part is largely inoperative for extending the cosmetic pencil, but is functional within the outer cap part.
  • a spring tab with a radially outward locking projection protrudes from the underside of the piston, which in the initial position of the piston is radially aligned with a locking opening in the peripheral wall of the foot part designed for the engagement of the locking projection and in the initial position of the piston from a radial projection formed on the inner wall of the outer cap part is held out of engagement with the locking opening against the spring force of the spring tab.
  • the locking projection of the spring tab on the piston in its initial position engages in the locking opening in the wall of the foot part, whereby the piston in its initial position prevents axial displacement in the slot sleeve is blocked and therefore also the screw sleeve and the slotted sleeve against one via the pin of the piston engaging in the thread of the screw sleeve Relative rotation are locked.
  • the locking projection is lifted out of the locking opening by the radial projection of the outer cap part, whereby the piston for the axial displacement in the slot sleeve and the screw sleeve for the relative rotatability with respect to the slot sleeve are released without additional measures.
  • the locking projection slides on the smooth inner surface of the slotted sleeve, but is prevented from lockingly engaging in the locking opening on the radial projection when the piston reaches its starting position again.
  • An inclined surface can be formed on the radial projection and / or the locking projection, on which the radial projection and the locking projection abut against one another during assembly in order to promote the lifting of the locking projection out of the locking opening.
  • the locking projection can, for example, be an axially extending rib on the inner wall of the outer cap part, which, when the foot part is inserted into the outer cap part, is pushed into an axial groove of the foot part, in which the locking opening opens, so that the locking projection protrudes from the end of the cap base of the outer cap part Rib is lifted out of the locking opening.
  • the rib in the groove forms a rotation lock for the foot part in the outer cap part, as a result of which the closure between them only needs to be designed as a relatively smooth-running axial closure, for example by being centrally on Cap base of the outer cap part radially resilient locking tabs are integrally formed, which snap resiliently behind the edge of a central opening formed in the base part.
  • an axial shoulder is formed on the foot part as a seat for the radial projection, which can be axially locked to the axial shoulder 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, axially between those of the Outer cap part and the base part formed two components on one of these a spring part axially pushing the components is formed and the locking opening, delimited by the axial shoulder, is formed above this.
  • 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 for the use of the cosmetic pen is relative to the outer cap part and thus to the slotted sleeve can be rotated by unintentionally releasing the lock by turning back the foot part.
  • the axial shoulder faces away from the cap base of the outer cap part and is axially overlapped by the radial projection.
  • the radial projection can also be designed as an axially extending rib in this embodiment, 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.
  • the spring part is formed 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 stud, which is in the locked state of the Radial projection engages in a complementary recess of the other component. In this way, an additional rotation lock of the foot part is achieved, whereby the spring part can be designed for a lower spring force.
  • 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 by other measures, e.g. the rotation lock specified above is held against rotation with the screw sleeve during normal operation using the spring clip.
  • 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.
  • this positive engagement can be overcome for an intentional unlocking of the foot part due to the resilience of the spring part.
  • the foot part 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 is exposed until it engages Axial shoulder and is rotatable on the locking projection.
  • a second guide groove for the round pin which is axially open at the end facing away from the axial shoulder and into which the round pin can be screwed out of the attack on the axial shoulder and the locking projection, and that second guide groove is formed 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 toward the foot part.
  • two diametrically opposed spring tabs according to the invention are provided on the piston, which, in the initial position of the piston when the cosmetic pen mechanism is located outside the outer cap part, both engage with a locking projection in a locking opening in the peripheral wall of the foot part and their radial free ends in the assigned locking opening at a distance of end of the outer surface of the foot part.
  • the locking projections for unlocking the cosmetic stick are not easy from the outside, but can only be accessed with a special tool.
  • a cup-shaped piston 1 which carries the cosmetic stick (not shown), is displaceable 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 on 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.
  • 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 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 this, 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 opposite 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 axially on one of the round pins 9 are aligned so that the underside of the round pin 9 can be shaped by means of 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 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 relative 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.
  • the locking of the cosmetic pen mechanism can be released by turning the screw sleeve 5 in the same direction relative to the outer cap part 8, as a result of which the round pin 9 into the second Guide groove 15 arrive and the cosmetic pen mechanism can be pulled axially out of the outer cap part 8.
  • 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 peripheral 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 9, 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 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 after the first extension of the Piston 1 releases from the cosmetic stick. 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.
