NT GFFHCE BALL-TYPE LIPSTICK APPLICATOR Application June 30, 1947, Serial No. 758,008

This invention relates to new and useful improvements in a lipstick applicator of the balltype.

The principal object of the invention is to provide a novel lipstick applicator, wherein the applicator proper is a rollably mounted ball for picking up lipstick material from a lipstick pencil therebehind and carrying the picked up material to the lips while rolling the ball over the lips.

A feature of the invention is a mounting for the ball incorporating a bezel forward of the middle plane of the ball and which not only acts as a scraper relative to the ball but also coacts with another part, also preferably incorporating a bezel, for permanently retaining the ball and permanently maintaining it freely rollable.

Another feature of the invention is a wholly removable inner barrel having a piston therein acted on by a spring also in the barrel, such spring for thrusting against the piston to resiliently forwardly urge the lipstick pencil to endwise advance against the rear side of the ball thereby always to maintain the latter embedded in the forward end of the lipstick.

A further feature is a means at the forward end of the barrel for engaging the forward end of the piston, so arranged that when the barrel is removed for insertion of a lipstick said means will ordinarily prevent the spring from ejecting the piston from the barrel, and also so arranged that when the barrel is held in the container with the rear end of the lipstick in a forward compartment in the piston the latter will be guided to a line of advance such that its forward end may pass beyond said means.

Still another feature of the invention is the provision of a piston not only having a forward compartment, but one also having a rear compartment, to establish a cup mounting for the forward end of the spring; there also being preferably present a cup mounting for the rear end of the spring, this mounting formed in a wall closing the rear end of the barrel.

Still a further feature of the invention is a permanent securement of the forward end of the spring in its cup mounting in the piston, whereby the piston and spring constitute a collection of permanently coupled parts easy to locate if ever accidentally ejected as such collection from the barrel following removal of the barrel from the container.

Another feature of the invention is a novel form of simple and reliable manually releasable latch means for securing the barrel within the container.

For further comprehension of the invention,

and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims inwhich the various novel features of the invention are more particularly set forth.

Fig. 12 is a partial longitudinal sectional view taken on the line l2-l2 of Fig. 11. v

Fig. 13 is a partial transverse sectional view taken on the line l3|3 of Fig. 11.

I'he lipstick container and applicator, according to the present invention, includes an outer casing l 5 comprising a cylindrical sleeve l 6 within the forward end of which is interiorly telescoped a main shell cup ll having a conically shaped front wall. The shell cup I! is suitably fixed in the sleeve It, as by force fit therein, or otherwise.

The shell cup l! at the center of its front wall has an opening l9, marginally of which the shell cup is shaped to present a, bezel 20.

A spherical ball 2|, made of metal or of any other suitable material, is freely rollably positioned behind the bezel an by an inner bezel 22 formed marginal to the opening 23 through the polygonal disc 2 suitably secured, as by the soldering indicated at 25, to the interior of the shell cup 11.

A friction-held cap 26 is carried by the container, with the rear end of the cap abutting the front end of the sleeve l6; which two parts are of the same external diameter, so that with the cap in place the main length of the container is of smooth contour throughout.

A lipstick pencil 21 has its rear end mounted in a forward compartment of a double hollow piston 23 movable axially of an inner cylindrical barrel 28; there being an expansile coil spring 28 seated at its forward end in the rear compartment of the piston 28, and seatedat its rear-end in the recess 39 in an end cap 31 secured to the rear end of the inner barrel 28.

The rear end of the barrel 28 is fitted tightly, and if desired is otherwise suitably permanently anchored, to the circular groove 32 cut in the forward face of the end cap 3 I.

Diametrically opposite sides of the cap 3i are formed with recesses each having a major sub division 33 and a reduced minor subdivision 3d. Latches are secured to the sides of the barrel 28 and each comprises a finger piece 35 disposed in the major subdivision 33 of its respective recess and a reduced neck portion 36 disposed i the minor subdivision 3 1 of its respective recess. The reduced neck portions 36 are formed on ends of the leaf springs 31 and the leaf springs are attached at their other ends to the sides of the barrel 28. The finger piece 35 of each latch is secured to the free end of the associated neck portion 36, and the forward end of the leaf spring 31 is welded, soldered or in any other manner secured to the sides of the inner barrel 28. The two latches extend along diametrically opposite sides of the barrel 28,

The two leaf springs 31 are resiliently biased to have their free ends spaced away from the adjacent sides of the barrel 28 so as to maintain the two finger pieces 35 normally projected to a predetermined extent from their recess subdivisions 33, as shown in Figs 3 and 10.

When the inner barrel 28 is inserted into the sleeve 16 of the outer casing 15, through the open rear end of the sleeve 16, and with the main or wider portions of the leaf springs 3! aligned with matching openings provided therefor in the rear end of the sleeve, a final slight endwise thrust on the inner barrel snaps the neck portions 36 of the leaf springs to interlock with the sleeve IS.

The matching openings of the sleeve [B are most clearly shown in Fig. 7, where they are shown as being formed in an inturned annular flange 39 at the rear end of the sleeve IS. Each such opening has a wider subdivision d8 interrupting the inner marginal portion of the flange 39, and a narrower subdivision 4! extended centrally beyond the subdivision 40. The subdivisions iii are of such width as to allow easy endwise passage therethrough of the main wider portion of one of the leaf springs 31, and the subdivisions iii are of a size to receive the neck portions 36 of the leaf springs 31.

While, during insertion of the barrel 28 into the sleeve IS, the main wider portions of the leaf springs 3'! are passing through the opening subdivisions til, the leaf springs 3'! are placed under tension by being compressed against the sides of the barrel 28; so that as soon as the wider portions of the leaf springs 31 have passed completely through the subdivisions 40, and the neck portions 36 of the leaf springs 3'! become aligned with the opening subdivisions M, the leaf springs snap outward so that shoulders 42 at the inner ends of the neck portions 38 engage the mate rial of the flange 38 on diametrically opposite sides of the subdivisions 4!. The parts are so shaped and dimensioned that when this last occurs, the shoulder 43 of the end cap 3! abuts the flange 39.

The spring 29, as already stated, has a cup mounting at both ends. At its rear end, such mounting is the recess 30 in the end cap 3 i. The cup mounting for the forward end of the spring 29 is the rear compartment of the piston 26'.

The spring 29, moreover, is permanently coupled to the piston 28'. Referring to Figs. 3 and 6, this coupling is by way of a means incorporating a disc 44 carrying a plurality of integral prongs .68. With several end convolutions of the spring 23 placed and constricted to encircle the prongs 4'5, the prongs are bent over to retainingly grip the convolutions, and the disc i i is permanently secured in the piston 23' by any suitable means, as by a force fit therein.

Due to the permanent interlock between the piston 28' and the forward end of the spring 29, these parts form a sub-assembly such that accidental loss of either spring or piston is almost an impossibility, even in the case Where, followin removal of the inner barrel 28 from the casing l5, as for insertion of a replacement lipstick, the piston 23 is accidentally ejected from the barrel by thrust from the spring 29; although ordinarily such ejection will be prevented by means new to be described.

Said means is a straight edged inturned flange portion 35 at the forward end of the barrel 2B, for engaging a forward edge portion of the piston 28'. As earlier mentioned, this arrangement will ordinarily prevent the spring 29 from ejecting the piston 28' from the barrel 28.

While we have illustrated and described the preferred embodiment of my invention, it is to be understood that we do not limit ourselves to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
