Definitions

  • a holder for lipsticks or the like is of the known kind comprising two relatively rotatable co-axial sleeves with a projecting control knob on the inner sleeve.
  • a sliding holder for the stick has lugs extending through slots in the inner sleeve and into slots in the outer sleeve.
  • One set of slots is longitudinal and the other helicoidal.
  • the slots in the inner sleeve are open at the end further from the control knob.
  • a transparent cover or shell for the stick is fitted onto the sliding holder.
  • the invention is characterized in that the shell has an internal shoulder equal in diameter to the end part of the sliding holder on which it is mounted.
  • the inner sleeve has an internal flange at that end further from the control knob and of a diameter between the internal diameter of the'shell and the diameter of the internal shoulder.
  • An annular space remains between the end of the she'll and 'the remainder of the sliding holder, its axial length being not less than the axial length of the flange.
  • the invention relates to holders forhousing pasty materials in stick form, such as make-up, pomades, cosmetics, pharmaceutical or veterinary materials or the like, of the type comprising two co-axial sleeves moulded of plastics material which can turn one inside the other, a control knob integral with one end of the inner sleeve and projecting from the corresponding end of the inner sleeve, a sliding holder for the stick which is movable in the inner sleeve and which carries at least onelug extending through a longitudinal slot in the inner sleeve and also engaging in a helical slot in the outer sleeve, one of these slots being longitudinal and the other helicoidal, the slot in the inner sleeve opening at that end thereof opposite to the end integral with the control knob, as well as a transparent protective shell for the stick, of which an open end is fitted onto the corresponding end of the sliding holder
  • the invention relates more particularly to means which ensure automatic ejection of the protective shell for the stick before the first use of the loaded holder.
  • Holders are also known in which the end of the shell fitted to the sliding holder is split to form longitudinal legs which open out slightly when the shell is fitted on the sliding holder and which serve as thrust members for the ejection of the shell by an internal flange on the corresponding end of the inner sleeve, somewhat in the same way as in the known holders just referred to above.
  • Such a holder is disclosed in my copending application Ser. No. 26,226 filed Apr. 7, 1970.
  • This last form of holder also has disadvantages. in fact, the lightly expanded legs of the protective shell exert a certain force on the inner sleeve, which gives rise to frictional forces which oppose relative sliding movement of the two components. Further, these legs are lightly compressed against the end of the sliding holder, so that, if the holders are in stock for a long time, said legs can remain curved and do not spread out sufficiently for the correct ejection of the protective shell.
  • the aim of the invention is to provide a holder in which the ejection of the protective shell of the stick can be made in a reliable manner and without having to overcome appreciable resistance in the operation of the device.
  • the end part of the protective shell for the stick mounted on the corresponding end of the sliding holder has an internal shoulder or counterbore of which the diameter is equal to the outer diameter of the corresponding end of the sliding holder, whereas the end of the inner sleeve, through which the stick can emerge, has an internal flange of which the diameter is between the internal diameter of the shell and the diameter of its internal shoulder or counterbore, an annular space remaining unoccupied between the annular end face of said end of the shell and the remainder of the sliding holder of an axial length at least equal to the axial length of said flange.
  • the protective shell of the stick is ejected in a reliable manner when it is engaged, around the whole of its periphery, by the corresponding end of the inner sleeve. Further, as this end of the inner sleeve is slit, it can easily open slightly so as to slide effortlessly over the outer surface of the protective shell of the stick. Further, when the holder is closed, no part is under constraint and in particular the flange at the end of the inner sleeve faces the pointed end of the protective shell for the stick so that, even if the holder is in stock for some time, none of the parts risks being submitted to permanent deformation deleterious to its correct functioning, in particular at the moment when the shell is ejected.
  • the diameter of the internal flange on the inner sleeve is at least equal to the internal diameter of the protective shell of the stick, there is no risk of the flange producing grooves in the stick when the latter is made to emerge or when it is returned into the holder.
  • the end of the outer sleeve, through which the stick emerges is recessed relatively to the corresponding end of the inner sleeve by an amountsufficient to allow said flange on the inner sleeve to open resiliently without appreciable force up to a diameter equal to external diameter of the shell.
  • FIG. l shows, in longitudinal section, an assemblied holder closed
  • FIG. 2 is a cross-section of the protective shell for the stick alone
  • FIG. 3 to a larger scale, a detail of FIG. 1, and
  • FIGS. 4, 5 and 6 illustrates the successive stages in the ejection of the protective shell for the stick.
  • the holder for housing a pasty material in stick form for example lipsticks, shown in its entirety in FIG. 1, comprises essentially a sliding holder 1 serving as a support for a stick of lipstick 2 covered with a protective shell 3 generally called an ogive, an inner sleeve 4, an outer sleeve 5, and a tubular metal body 6 usually enclosed within a cover 7, the base 9 of the inner sleeve 4,
  • the sliding holder 1 is provided with two diametrically opposed radial lugs, such as 12, which extend through longitudinal slots 14 in the inner sleeve 4 and which are engaged, at the same time, in two helicoidal slots l6, 17 formed in the inner cylindrical face of the outer sleeve 5.
  • the metal body 6 engages the outer sleeve with a certain friction, preferably very small so as not to deform the sleeve 5 on'which it is mounted and not to risk jamming of the mechanism.
  • the upper part of the protective shell 3 for the stick of lipstick 2 is, at least in diametral view, of ogival form 24 (FIG. 2), whereas the main part 25 of this shell is of cylindrical form; its'end fitted to the corresponding end of the sliding holder 1 has an intemal shoulder 27 or counterbore of which the diameter D1 is equal to the diameter D2 (FIG. 1 of said end of the sliding holder.
  • the end of the inner sleeve 4, opposite to that which is integral with the control knob 9, that is to say the end through which the stick 2 emerges, has an internal flange 28 (see also FIG. 3) of which the diameter D3 is between the internal diameter D4 (FIG. 2) of the protective shell 3 and the diameter D1 of its internal shoulder 27.
  • annular space 29 (FIGS. 1 and 4) remains unoccupied between the annular end face of the end ofthe protective shell 3 fitted on the sliding holder 1 and the remainder of said sliding holder.
  • the axial extent E of this annular space is at least equal to the axial length of the flange 28 on'the inner sleeve 4, so that this flange can, at a certain moment, enter this annular space, as will be seen below.
  • the remainder of the sliding holder 1 has an outer diameter D5 (FIG. 1) substantially equal to the outer diameter D6 of the protective shell 3 for the stick.
  • the end of the outer sleeve, opposite the control knob 9, is recessed over a length L (F IG'. 1) relatively to the corresponding end of the inner sleeve 4.
  • This length is given a value sufficient to allow the flange 28 to open resiliently without appreciable force up to a diameter equal to the oute diameter D6 of the protective shell 3.
  • cylindrical part 25 of the protective shell 3 is not opposite this cylindrical part of the shell, but faces the pointed end-thereof, that is to say that it is a long 'way from being in contact with it.
  • such as a lipstick comprising an inner sleeve having at least one longitudinal slot; an outer sleeve concentrically and rotatably surrounding said inner sleeve and having at least one helical groove in its inner wall; a stick-support axially movable within said inner sleeve,
  • said inner sleeve having at its lower end an actuating knob which protrudes from the lower end of said outer sleeve; a stick; said stick-support being adapted to receive and mount said stick; and a protective shell covering said stick, the lower end portion of said protective shell being removably telescoped on a corresponding upwardly directed end portion of said sticksupport, which stick-support end portion has a reduced outer diameter with respect to the outer diameter of the portion of I said stick-support immediately therebelow; and which shell defines a counterbore at and internally of the lower end portion thereof of a diameter greater than the internal diameter of the shell immediately above the counterbore; the improvement comprising providing at the open upper end of said inner sleeve an inwardly directed resilient flange means defining an inner diameter slightly less than the inner diameter of said shell counterbore but greater than the internal diameter of the remainder of the inner portion of said shell, the counterbore of the shell having an axial length less than the axial length of said reduced diameter end portion of the stick-support by an amount
