16 Claims.

This invention relates to certain improvements in containers for lipsticks, eyebrow pencils and similar soft pasty cosmeti a type of container is supported in a carrier an enclosed casing to then withdrawn into the cs, and particularly to in which the cosmetic stick which is moved from expose the stick for use and casing and covered by a cap member, this type of dispenser being generally known as a swivel-type lipstick container.

One of the inherent faults of the above type of lipstick containers is that frequently in packing the container for shipment, or carrying the same around in a handbag, or

idly playing with the same, the members composing the container are liable to be accidentally each other with the result forced into contact with rotated in relation to that the cosmetic is the inside of the cap,

creating disgurement and soiling of working parts and deforming the shaped end of the cosmetic, to the annoyance of the user, and to the prejudice of the market.

It is, therefore, the main object of this invention to provide a simple means intentional movement of the cosmetic stick by which the uncasing is eiectually prevented.

It is a further object to provide a cosmetic container of the above nature in which means are provided for interlocking propelling means of the when assembled thereon, vide for such interlocking readily applied to a standard or the rotatable cosmetic casing with the cover and especially to promeans which may be stock lipstick with the minimum of changes and parts.

With these and other objects in view, the invention consists in certain novel features of construction, combinations and arrangements of parts, as will be more fully disclosed in connection with the accompanying drawing and as set forthv in the annexed claims,

In the drawing:

Figure 1 is a partial side elevation and partial lipstick container embodying of this invention, and showing the their normal assembled locked position. 2 is a longitudinal sectional view through cover showing them in with the locking eleview of the inside shell of the elements of the AFigure 4 is a detailed perspective view of an insert shell, which is adapted to be inserted within.tlie cover member, an tures of the locking means.

d discloses other ieaf (Cl. 20G-56) Figure 5 shows a side elevation view of a modified construction, portion of said view being broken away to better show the locking feature.

Figure 6 shows fragmentary separated views of cover and container members showing a further 5 modification of the form disclosed in Figure 5.

Figure l is a fragmentary sectional View of a hinged cover swivel lipstick container showing the locking feature embodied therein.

Referring now to the drawing in which like nu- 10 merals refer to corresponding parts throughout the several views: the numeral I0 refers generally to a dispensing container comprising an outside tubular casing II and inside shell I2 rotatably mounted therewithin. Disposed between the 15 casing II and shell I2 and adapted to be retained and carried by the outside easing II is a spring sleeve I3 having a helical groove or slot I4 extending from end to end thereof.

The base or lower end of the inside shell I2 is 20 provided with an integral head I5 which is adapted to extend beyond the outside diameter of the outside shell II. The head i5 is preferably provided with a knurled surface as best shown in Figures 1 and 3 to assist in manipulating the 25 same, but it is to be understood that the head I5 could be made as well of any polygonal shape to omit the knurled portion within the scope of the invention. The upper end of the inside shell I2 has a portion indicated by the numeral I6 30 formed outwardly in a manner to be more specifically pointed out later, this deformed portion I6 for the present serving to rotatably interconnect the inside shell I2 with combined outside shell IIl and sleeve I3, and adapted to engage S5 against the upper annular edge of the spring sleeve I3 as a thrust bearing.

Mounted to slide within the inside shell I2 is a v cosmetic stick carrier inthe form of a cup I'I in which is held a cosmetic stick I8. The inside 0 shell I2 is formed with a longitudinal slot I9`extending substantially the entire length of said shell. Within, adapted to slidably engage the slot I9, there is provided a head 20 of a pin 2 secured to the cup I'I as best shown in Figure 2. 5 The pin 2l, if desired, may project a substantial distance within the cup to be embedded within the material of the cosmetic stick as a better means for holding the stick I8 within the cup I'I, The head 20 of the pin 2l is adapted to pro- 50 ject beyond the slot I9 and engage within the helical slot IG of the sleeve I5 previously mentioned, and as will be evident, the merc rotation of the inside shell I2 relative to the outside casing II through the manual operating of the head must protrude in use.

' which isprovided with I5 will positively project and retract the cosmetic stick I8 carried by the cup I1.

'Ihe forward end of the outer shell II is rounded inwardly as at 22 tol provide for a smooth surface surrounding an opening 23 in the end of the outside casing through which the stick Il The container I0, when the cosmetic is Withdrawn, is adapted to be closed by a closure cap 24 as shown in Figures 1 and 2, a crowned closing end 25 and is designed to telescope over the entire length of the outside shell II. Up to this point the construction disclosed is old in the art of lipstick containers and forms no part of the present invention except as used in combination with the interlocking feature hereinafter disclosed.

In accordance with this invention there is provided means whereby the inside shell I2 and complementary operating head I5 are interlocked against rotation within the casing II by the mere assembling of the cap 24 upon the container I 0, thus preventing accidental longitudinal movement of the stick carrying cup I1. While the specific construction effecting this locking feature may be somewhat varied as shown by `the modifications herein, the preferred and simplest construction is disclosed in Figures 1 to 4 inclusive. Thus, there is provided a stepped cup-like insert shell 26 comprising an upper larger cylindrical portion 21 and a lower smaller portion 28. The smaller portion 28 is provided with 'a series of scallop-like longitudinal projections or utes 29, which assume in transverse cross section a sinuous annular ring.

The insert shell 26, shown in Figures l and 2, is adapted to be disposed in the upper end of the closing cap 24 adjacent to crowned end 25. The outer diameter of the cylindrical section 21 of the insert shell 26 is such, relative to the inside diameter of the closure cap 24; that said insert 4shell 26 is assembled into its permanent position preferably by a drive or force fit to assure a rigid and non-rotatable connection between the parts. The insert shell 26 is originally formed with a crown or base end closing the smaller section 28 of said shell, and conjoined by a noticeable radius that naturally provides for a chamfered or round bevel-like portion 30 which Ais adapted to merge smoothly into the lower ends of each of the flutes 29, (see Figure 4). Subsequently, the base of this shell may be pierced out to provide for an opening 3l to allow for suitable clearance for a new cosmetic stick in case its lengtlh should cause it to extend upwardly therewithin.

'I'he upper outwardly formed portionl I6 of the inside shell I2 previously mentioned is like- Wise formed with a series of corresponding longitudinal scallop-like projections or flutes 32 presenting a sinuous ring (see Figure 3) which permits interengagement with the flutes 29 of the insert shell 26 in the cover 24.

Now when the cover 24 is assembled upon the casing lil its full length, the flutes 29 of the insert shell 26 are adapted to slidably interiit with the corresponding flutes 32 in the expanded portion I 6 of the inside shell I2 in an interlocking manner; if, perchance, the iiutes 32 are not in proper alinement with the flutes 22 of the insert shell 26, they will be automatically forced into such alinement, coincident with the telescoping of the cov'er 24 and the container l0, by reason of the chamfer 30 on the end of the iiutes 29 .previously mentioned. 'I'hus it will be evident that through this interlocking feature when the and well known i cover 24 is upon the casing I0 it will not be possible to actuate any movement of the carrier cup I1.

In Figure 5 there is shown a modified form of the interlocking feature wherein the insert shell 28 is omitted from the cover 24a, and in place inside shell I2a adjacent to the head I 5a. The

upper end of the section 36 may be likewise chamfered, as at 31, to facilitate the full assembly of the cover 24a.

In case it is objectionable to place visible flutes or teeth on the lower end of the cap 24a in Figure 5, this may be avoided by a construction disclosed in Figure 6, wherein the lower end of the cap 24h is provided with an inner attached collar 38 having the interlocking iiutes 39 positioned within the inner end of the cover 24b adjacent the open end. The collar 38 may be made secure to the cover 24hby being spun over and forming an attaching bead 40 around the lower annular end of said cover 24h. Obviously the construction of the inside shell may be formed the same as in the modification of Figure 5 as shown by the fragmentary view in Figure 6 except' for the relative diameter of the enlarged section 36a. v

In Figure 7 there is shown the interlocking feature applied to a lipstick container having a hinged closure cap. Herein is' disclosed an outer casing IIC having a projecting circumferential rib 4I adjacent the upper open end. A relatively narrow cap 42 is attached to the rib part 4I of the casing by a hinge 43, a construction well known in the art. An insert shell 44 is axed within the interior of the cap as by soldering, and said shell 44 is formed with suitable projecting elements similar to those disclosed in the preferred form of the invention, and designed to have interlocking engagement with the correspondingly formed ring 45 integral with the upper end of the inside shell I 2c. Obviously the closing of the hinged cap 42 effects the desired locking feature.

Before concluding this specification, attention is called to the fact that one of the outstanding desiderata of this interlocking feature for lipstick containers resides in the simplicity of construction, wherein said interlocking feature can be applied to the several types of stock lipstick containers disclosed without the necessity of changing the established set-up in tools or operations making such stock lipsticks, it being only necessary to slightly reform one of the parts and add a new shell to the cover.

While this invention has been shown and described in several forms,it will be understood that other changes and variations may be made in the specific constructions shown and described without departing from the scope of the invention as defined in the appended claims.
