Application January 16, 1942, Serial No. 426,937
- 7 Claims. (ill. 132-8817) This invention relates to lipsticks of the cartridge type in which a stick of cosmetic material for application to the lips is mounted in a. case or holder adapted to be drawn across the lips, and in which there is provision for moving the cosmetic stick relatively to the case so as to maintain the end of the stick in a desired position relatively to the end of the case.
It is an object of the present invention. to provide an improved lipstick of this type in which application of the cosmetic to the lips is facilitated.
A further object oi the invention is to provide a sleeve or hollow portion of the case through which the cosmetic stick is adapted to extend and which is adapted to facilitate application of the cosmetic to the lips.
i shaped to maintain one or morepointed portions at the end of the cosmetic stick.
A further object of the invention is to provide a sleeve or hollow portion. of the case which is shaped to conform to the lips.
In order to illustrate the invention more fully several embodiments thereof will now be described cy way of example with reference to the accompanying drawing in which:
l is a side elevation of a lipstick accord= ing to the invention;
Fig. 2 is a front elevation of the lipstick of l with the cover or cap thereof removed;
Fig. 3 is a central vertical section on the line of Fig. I. with certain parts shown in ele vation, cosmetic stick not being shown in this figure;
Fig. is a section through the sleeve or hoilow shaping portion or the invention taken on the line l-Q of Fig. 2;
Fig. is a plan view of the shaper or sleeve of Fig. 4 looking from the direction of the arrows 5-5 in Fi i;
Fig. 6 is a section on the line of Fig. 3;
Fig. 7 is an elevation of a modification.
Referring to Figs. 1-3, the lipstick comprises a holder or case iii of generally cylindrical form adapted to receive a. stick It oi cosmetic material. The cosmetic stick it may be permanent- 13! secured in the cup or it may be removably mounted therein so that it can be replaced by a new stick after use as well known in lipsticks.
In the embodiment shown, the cup l 4 is mounted on a screw it and is held from rotation by cars ll engaging grooves it in the inner wall of the case iii. Consequently, when nut llX engaging the screw it is rotated, the cup it (and the stick of cosmetic material it carried thereby) will be raised or lowered relatively to the case, depending on the direction of rotation of the nut. As will appear from Figs. 1 and 2, the nut liX projects through slots in depressed portions it of the case it] so as to be accessible for actuation and has a rnurled outer surface.
Attention is directed to the fact that, as shown in Figs. 5 and 6, the cosmetic stick it in this embodiment is non-circular in cross-section, having a straight side 55X. The cup id is consesilently formed with a similar straight side Ma, as shown in Fig. 6.
[it the top of the case iii, the cosmetic stick it extends through a sleeve or hollow portion which is an important element of the invention. This sleeve or hollow portion 2d may be constituted by the upper part of the body of the case it itself or may be a separate element as shown fitted in the case 26 so as to prevent relative movement between the sleeve and case. The interior diameter of the sleeve or hollow portion is only slightly greater than the exter= rial diameter of the cosmetic stick it so that the latter will have a close fit therein as shown.
Referring to Figs. 2, 3, and 4, it will be seen that the baclrportion 2i oi the sleeve Ed is higher than the front portion thereof and is connected with said front portion by sloping side portions 23. Consequently the sleeve or hollow portion 263 of the case will act as a shapcr for the cosmetic stick is and the wearing down of the cosmetic stick in use will be controlled and limited by the form of the sleeve, a pointed portion 2% (acute-angled in cross-section) being maintained in the cosmetic stick adjacent the high back portion 2i of the sleeve. The back portion 28 of the sleeve may be bevelled at the top as shown by Fig. 4 or may be fiat.
Due to the fact that the top surface of the sleeve or hollow portion 26 is generally a conic section of a cylinder (i. e. an ellipse) the portion 2c of the cosmetic stick is not only pointed when viewed in vertical cross section as shown in Fig. 4 but is also pointed when viewed in plan as shown in Fig. 5. The last mentioned view is not taken directly from above but in the direction 01' the arrows 5-5 in Fig. 4 soils to show the generally elliptical form 01' the em. of the cosmetic stick as maintained by the shaping action or the sleeve or hollow portion 20.
As shown in Figs. 2-5, the sloping sides 23 oi. the sleeve 20 in this embodiment are formed with recesses 25 and consequently the cosmetic stick in use will wear down in corresponding form, providing a recessed portion 26 (Figs. 4 and 5) across the top of the stick.
, The low front portion 22 of the sleeve 20 in the embodiment of Figs. 1-5 is provided with a straight inner edge 21 corresponding to the aforementioned straight side ISX or the cosmetic stick ii for a purpose to be explained. It will be understood that, due to the rotation-preventing means l1-|8 between the cup l4 and case III, the cosmetic stick I5 is always maintained in the same orientation with respect to the case l and sleeve 20.
In use, the cosmetic stick I is propelled by nut IIX until it is substantially flush with the top surface of the sleeve 20. The mechanism for axially moving the cosmetic stick is preferably such that the stick may be moved in either direction (propelled or repelled) so that the desired.
adjustment relative to the top of the sleeve 20 may be secured. Any desired means may be used for moving the stick: for example, the stick may merely slide axially within the case. However, with the specially formed sleeve or hollow shaper portion of the present invention, it is preferred to have screw means such as shown which will provide relatively delicate and accurate adjustment and also serve to retain the cosmetic stick in adjusted position.
In any event, means must be provided to prevent rotary movement of the cosmetic stick, and the type of propelling means used in some lipsticks to-day, involving spiral or helical movement of the cosmetic stick, is not suitable for the present invention where, because of the special shape of the sleeve 20, it is essential that the same orientation of the cosmetic stick with respect to the sleeve be maintained at all times.
After the position of the cosmetic stick has been adjusted as aforesaid, the lipstick is drawn across each lip in the usual way except that more pressure than usual may be exerted upon the lipstick due to the support afforded by the sleeve 20 surrounding the end of the cosmetic stick. In other words, the sleeve 20 acts as a support for the cosmetic stick during use of the lipstick and this efiect is enhanced by the aforesaid close fit between the cosmetic stick and the sleeve.
In applying the cosmetic to the upper lip, the high back portion 2i of the sleeve 20, which is adjacent the pointed portion 26 of the cosmetic stick i5, may be used as a guiding finger and may be made to follow the natural curved line of the upper lip or any desired curved line different from such natural line. The recesses 25 oi the sleeve and the corresponding recessed portion 26 of the cosmetic stick conform to the lip an drawn across the lip.
In applying the cosmetic to the lower lip, the low front portion 22 of the sleeve 20 acts as a guide in drawing the lipstick along the relatively straight line of the lower lip. This effect is aided by the straight-line edge 21 of the sleeve. Alternatively, if desired, the position'of th lipstick may be reversed and the finger formed by the high back portion ,2! of the sleeve, used to follow act as a guiding channel as the lipstick is the line of the lower lip. However this special guide is not so necessary for the lower lip"since',""
as mentioned above, the lower lip isrelatively straight.
In either case, the recesses 25 of the sleeve 20 act as a guiding channel and the sleeve 20 functions as a whole to support the cosmetic stick and take up part of the pressure used in applying the lipstick. Moreover, as' the cosmetic stick wears down in use and is moved by actuation of the nut "X .to the desired position flush with the top surface of the sleeve 20, it will always be maintained in the shape defined by the sleeve.
This is in contrast to th usual form of lipstick where the pointed end which is present when the lipstick is originally purchased quickly wears down to a flat end surface, making accurate al gplication of the cosmetic difficult if not imposs e.-
Another advantage of the present invention is that, as a result-of the increased pressure that can be used without breaking or deforming the cosmetic stick due to the protective action of the sleeve 20, th cosmetic can be spread and rubbed in as well as applied in a single operation and without the subsequent use of the fingers. Moreover the outlining of the lip (with the aid of the guiding finger) andthe filling in of the outline can be done at the same time.
Fig. 7 shows a further modified form of sleeve 20b in which sloping side portions 23b having recesses 25b are provided as in the case of Figs. 1-5. However, in the sleeve of Fig. '7, both the back portion 2lb and the front portion 22b are of substantially the same height so that two guiding fingers are provided and two pointed portions are maintained on the cosmetic stick. In use, the lipstick of Fig. 7 may be held with the front and back portions of the sleeve facing in either direction as desired.
Although several forms of the lipstick of the invention have been shown and described, it will be appreciated that still other forms may be used without departing from the spirit of the invention and the scope of the appended'claims. In particular, the means for moving the cosmetic stick may be of any type desired as long as rotation of the stick is prevented, and rotation may be prevented in any desired way, not only by special rotation-preventing means as shown but, for example, by making the entire case of noncircular form in cross-section to correspond to the form of the cosmetic stick. Moreover it will be understood that the specially shaped sleeve or hollow shaper portion through which the cosmetic stick extends can be part of the case or container itself so that a single element will serve as both a container and shaper for the cosmetic stick.
What is claimed is:
1. In a, cartridge-type lipstick, a hollow portion through which a stick of cosmetic material is adapted to extend, the sides of said portion being formed with aligned recesses generally conforming to the cross-sectional shape of a lip and adapted to act as guides when the lipstick is drawn across a lip, and means for preventing rotation of the cosmetic stick relatively to the hollow portion.
2. In a cartridge-type lipstick, a hollow portion of generally cylindrical form through which a stick of cosmetic material is adapted to extend, said hollow portion having astraight side at the outer end thereof corresponding to a fiat side of the cosmetic stick, said hollow portion also being formed with aligned recesses in the sides thereof at right angles to said straight side, said recesses generally conforming to the cross-sectional shape of a lip and adapted to act as a guide when the lipstick is drawn across a lip.
3. In a cartridge-type lipstick, a hollow portion through which a stick of cosmetic material is adapted to extend, the back of said portion being higher than the front thereof and being connected to the front by sloping sides which have aligned recesses therein generally conforming to the cross-sectional shape of a lip and adapted to act as guides when the lipstick is drawn across a lip, and means for preventing rotation of the cosmetic stick relatively to said hollow portion.
4. A cartridge-type lipstick comprising a case, means for receiving a, stick of cosmetic material within said case, a hollow portion at one end of the case, means for moving the cosmetic stick in both directions axially with respect to the case and hollow portion while preventing rotation of the cosmetic relatively to the 'case and hollow portion, the outer end of said hollow portion being formed with aligned recesses generally conforming to the cross-sectional shape of a lip and adapted to act as a guide when the lipstick is drawn across a lip.
5. A lipstick according to claim 4, in which the means for axially moving the cosmetic stick is adapted to maintain said stick in the position to which it has been moved.
' straight edge corresponding to the straight side of the cosmetic stick, and sloping sides connecting said front and back, said sides having recesses generally conforming to the cross-sectional shape of a lip and adapted to act as a guide when the lipstick is drawn across a lip, means for moving the cosmetic stick axially relatively to the case and through said hollow portion into a position where the end of the cosmetic stick is substantially flush with the end of the said portion without causing rotation of the cosmetic stick relatively to'the case and hollow portion,
the cosmetic stick being initially shaped at the end thereof with a transverse recess to conform generally to the shape of the end ofthe recessed hollow portion and said portion thereafter serving to maintain the shape of the end of the cosmetic stick as said stick wears down in use.
