E. SCHALL Dec. 28, 1954 APPARATUS FOR REHOVABLY MOUNTING LIPSTICKS OR THE LIKE Filed Dec. 7. 1951 United States Patent APPARATUS FOR REMOVABLY MOUNTING LIPSTICKS OR THE LIKE Egon Schall, New York, N. Y., assignor to Lever Brothers Company, New York, N. Y., a corporation of Maine The present invention relates to means for mounting a lipstick, or the like, in a casing.

In known dispensers of the above type removal of a lipstick from the dispenser casing is difficult without soiling the fingers. Similarly it is ditficult in known dispensers to exchange the lipstick if it is desired to do so.

One of the objects of the present invention is to provide a means for removably mounting a stick of material to be dispensed in a dispenser casing so that it will be possible to replace one stick of material in the casing with another stick of a dilferent type of material, and in this way the same casing may be used for the different types of material to be dispensed.

Another object of the present invention is to provide a removable mounting of the above type which is of an exceedingly simple construction so that one type of material to be dispensed may be replaced by another type with a minimum of effort.

A further object of the present invention is to provide a removable mounting of the above type which is of a sturdy construction so that the same will be usable over a long period of time.

Yet another object of the present invention is to provide a removable mounting of the above type with a safety means to prevent damaging thereof.

An additional object of the present invention is to provide a means for covering the material removed from the casing.

With the above objects in view the present invention mainly consists of an apparatus for removably mounting, in a dispenser casing, a stick of material to be dispensed, this apparatus comprising a support member to be mounted in the casing for movement along a predetermined axis. A carrier is also mounted in the casing to carry a stick of the material to be dispensed, and a tubular member is associated with the carrier to be located about the material to be dispensed so as to at least partially cover the same. A first connecting means is mounted on the carrier and one of the support or tubular members for detachably connecting this one member to the carrier by rotation with respect thereto, and a second connecting means is mounted on the carrier and the other of said support and tubular members for detachably conmeeting this other member to the carrier by translational movement with respect thereto.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:

Fig. l is a sectional, partly fragmentary view of one possible apparatus for carrying out the present invention;

Fig. 2 is an exploded view of associated parts of the apparatus illustrated in Fig. 1;

Fig. 3 is an exploded view of a dilferent embodnnent of the parts illustrated in Fig. 2;

Fig. 4 is an exploded view of another embodiment of the parts shown in Fig. 2; and

Fig. 5 is an exploded view of still another embodiment of the parts illustrated in Fig. 2.

Referring now to the drawings, there is shown in F g. 1 a casing having a tubular base member 11 provided with a closed bottom, this closed bottom having a flange 12 which may be knurled so that tube 11 may be held 2,698,085 Patented Dec. 28, 1954 ice non-rotatably by the user. The tubular base member 11 is formed with at least one elongated slot 13.

Loosely located about tubular member 11 and resting on the shoulder 14 thereof isa cylindrical member 15 having an upper end located immediately below a shoulder 16 formed in the upper end portion of tubular member 11. This cylindrical member 15 is formed with a helical slot 17 extending from one end thereof to the other end thereof.

A tube 18 is located about the cylindrical member 15, this tube 18 making a fairly tight frictional contact with the member 15 so as to press the same inwardly toward the tube 11 while permitting free rotation of members 15 and 18 with respect to tube 11. The inward move ment of tube 15 causes the top end thereof to be located immediately below shoulder 16 so that members 15 and 18 cannot be removed from tube 11 except by forcibly sliding member 18 01f member 15. The tube 18 is provided at its upper end with an inwardly extending flange to improve the appearance of the casing 10.

A pin 19 extends through the slot 13 and has a head 20 located in the helical groove 17 of cylindrical member 15, this head being wider than slot 13 so that pin 19 cannot fall through this slot. The tube 18 holds the head 20 in the helical groove 17.

A cover member 21 is provided to cover the entire casing, this cover member 21 being adapted to frictionally engage the side portion 22 of the tubular base member 11 so as to be easily removable therefrom. If desired the outer surface of cover member 21 may be knurled.

Mounted for movement along a predetermined axis within the tube 11 is a support member 23 which is hollow, internally threaded adjacent the upper open end thereof and formed with a side aperture 24 through which pin 19 extends. It is thus apparent that upon rotation of tube 11 with respect to tube 18, the cylindrical member 15 remaining stationary with the tube 18, the support member 23 will move up or down in the tube 11 due to the movement of head 20 of pin 19 in the helical slot 17 of cylindrical member 15. Thus support member 23 is shown in an enlarged scale in Fig. 2.

A carrier 25 is threaded adjacent its lower end so as to be detachably connected to the threads of support member 23, this carrier being adapted to carry a stick of material to be dispensed, such as, for example, the lipstick 26, shown in dot dash lines in Fig. 1. This carrier 25 may be hollow to suitably support the stick 26 and is slightly conical at its upper side surface, as is shown on an exaggerated scale in Fig. 2. The carrier 25 is provided on or adjacent the conical side surface portion thereof with at least one projection 27, four of these projections 27 being used in the particular embodiment illustrated in the drawings. As is apparent from Figs. 1 and 2 the projections 27 have an upper substantially semicircular edge.

A tubular member 28, which may be closed at the upper end thereof, is adapted to be located about the stick 26. This tube 28 is provided at its lower end with inwardly extending recesses 29 which are substantially semi-circular so as to matingly engage with the projections 27, and the lower end portion of tube 28 is slightly conical, as shown in exaggerated scale in Fig. 2 so as to frictionally engage the upper slightly conical side portion of carrier 25.

The operation of the above described structure is believed to be evident. When it is desired to use the stick 26, the cover 21 is removed from the casing 10 and the members 18 and 11 are turned with respect to each other so as to move the support member 23 upwardly to the top of the casing 10. The tube 28 is then slipped off from the carrier 25, which is threadedly connected to support member 23, as shown in Fig. 1, so as to expose the stick 26. Then the tube 28 is replaced about the stick 26 and on the carrier 25, the members 18 and 11 are rotated with respect to each other to move support member 23 to the bottom of tube 11, and the cover 21 is replaced. In Fig. 2 the tube 28 is shown out of line with the pro ections 27 to illustrate that the tube 28 may simply be slipped onto the carrier 25 so that the lower end of tube 28 engages the top edge portions of projections 27. It is then only necessary to turn the'tube 28 slightlyso-that it may be further moved onto carrier 25 and have the recesses 29 aligned with projections 27 in a very simple manner. The tube 28 remains connected to the carrier 25 by frictional contact therewith.

If it is desired to replace stick 26 by another type of stick, the support member 23 is again raised to the top of the casing 10, in the manner described above, after cover 21 has been removed. The tube 28 is then turned, instead of being removed from the carrier 25, and because of the engagement of projections 27 withrecesses 29, the carrier 25 turns with the tube 28 so as to be unscrewed from the support member 23. After carrier 25 is removed from support 23, it remains connected to tube 28 by the frictional engagement between these

members

28 and 25. Then another assembly of

elements

28 and 25 carrying a different type of stick 26 is threaded into the support member 23 so that the same casing and cover 21 are usable with this othertype of stick 26.

It will be noted that when an assembly of

elements

28 and 25 is connected to the support 23, the tube 23 is turned so as to also turn the carrier 25 frictionally connected thereto and thread the carrier 25 onto the support 23. When all of the threads on the carrier 25 have engaged the threads of supports 23, continued turning of the tube 28 will only result in slidable movement of recesses 29 over projections 27 so that, in this way, the threads on

members

23 and 25 are protected and too tight an engagement between these threads is prevented.

As is shown in Fig. 3, the support member 23' may be provided with recesses 29' and with an inner conical upper surface so as to engage projections 27' on carrier 25' and the lower conical side surface portion of the latter, the tube 28' then being threadedly connected to the carrier 25. This construction is capable of producing thesame results as the construction shown in Figs. 1 and 2, the only difference being that carrier 25' is detachable from support member 23' by translational movement Withrespect thereto and the tube 28 is detachable from carrier 25' by rotation with respect thereto.

As is apparent from the above description, the essence of the invention resides in making one of the

members

23 or 28 detachable from member 25 by such a movement which does not detach the other of the

members

23 or 28 from the carrier 25 and, vice-versa, to make the other of the members 23 or 28-detachable from member 25 by a movement of such type which does not detach the first-mentioned of the

members

23 or 28.

In Fig. 4 there is illustrated a further embodiment of the invention which is the same as that shown in Fig. 2 except that the carrier 25 is formed with a bayonet slot 30 which engages a pin 31 fixedly mounted within the support 23" to render carrier 25" detachable from support 23"by rotation with respect thereto.

In the specification and the claims which follow all references to threaded connections are intended to include both threaded connections, shown in Figs. 1, 2 and 3, and a bayonetslot and pin connectiomshown in Fig. 4.

In Fig. 4 a further embodiment is shown in which the support member 23 is hollow and internally-threaded in the same manner as in the embodiment shown in Figs. 1 and 2. The tubular case member indicated in this embodiment with reference numeral 32 is provided with two oppositely directed

screw threadings

33 and 34 spaced from each other by shoulder 35. The lipstick cover 36 is provided with a screw threading 37 meshing with the screw threading 34.

It is evident that a device of the above type operates in the same manner as the removable lipstick mounting shown in Figs. 1 and 2.

In order to secure the lipstick to the support 23 the same is inserted in the tubular case member 32 and the cover 36 screwed thereon. Then the thus-assembled unit is screwed into the internally screw-threaded support 23 until shoulder 35 abuts against the upper edge of the support. This prevents further turning of'the tubular case member relative to the support and further turning of the cover 36 will result in detachment of the cover from the tubular case member 32.

If it is desired to remove the case member 32it is'only necessary to screw the cover 36 on screw-threading 34 of the case member 32 and turn it continuously into the opposite direction until the cover abuts against the shoulder 35; further turning 'ofthe"cover'will detach the case ingember 32 together with the cover from the support Although the above description refers specifically only to a lipstick, it is to be understood that the present invention is applicable to any stick of material to be dispensed.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of apparatus for removably mounting a stick of material to be dispensed in a casing differing from the types described above.

While the invention has been illustrated and described as embodied in an apparatus for removably mounting a lipstick in a casing, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
