Description

BACKGROUND OF THE INVENTION

This invention relates generally to controlled feeding application of cosmetic liquid, such as mascara, to eye lashes or to other facial zones; and more particularly relates to an improved device to feed mascara from a container onto brushes on a belt, at controlled rate, as for example as related to desired delivery of mascara to eye lashes.

There is need for simple, compact, easily manually controlled and operated devices that accurately delivers mascara to eye zones, at controlled rates. Prior devise lacked the related integrated improvements, in a highly compact assembly characterized by the present invention.

SUMMARY OF THE INVENTION

It is a major object of the invention to provide an improved, compact, mascara application device that basically comprises:

a) a container for mascara

b) a manually operable actuator,

c) feed mechanism carried by the container to feed mascara to a loading station, in response to operation of the actuator,

d) a belt having applicator brushes to receive mascara at the loading station as the actuator is operated,

e) guide means to guide actuator induced belt displacement relative to the container to position the brushes for mascara application to eye lashes.

As will be seen, the belt is typically a compact, endless belt; the mechanism includes an actuator that is manually controllably rotatable; and the actuator is operatively coupled to both the feed mechanism and to the belt whereby the user may simultaneously control both displacement of mascara fluid onto the belt, and belt brush displacement relative to the user's eye lashes for accurate control of mascara application.

Another object is to provide a spindle, and first gearing associated with the spindle to rotate the spindle about a transverse axis as the actuator is manually rotated about a longitudinal axis, and second gearing associated with the spindle and belt to drive the belt endwise in response to said spindle rotation. Such first gearing may advantageously include interengaged teeth on an actuator part and extending about the longitudinal axis, and teeth on the spindle extending about the transverse axis. Also, the second gearing typically includes gear teeth on the belt at its inner side, with belt brushes presented at the belt outer side.

Further, as the actuator is rotated, it displaces a pusher in the container to in turn displace or feed mascara to the loading zone.

These and other objects and advantages of the invention, as well as the details of an illustrative embodiment, will be more fully understood from the following specification and drawings, in which:

DETAILED DESCRIPTION

Referring first to FIGS. 1-3, they show a representative mascara application device 10 that includes, generally, a container 11 for liquid mascara having a main body 11a and a cap 11b fitting endwise toward body 11a, and being endwise removable. Feed mechanism shown generally at 12 is carried by the container to feed mascara 13 in body 11a to a loading station or zone indicated at 14 in FIG. 8 in response to operation, such as rotation of a manually rotatable actuator 15, after removal of cap 11b.

An endless belt 16 has or carries applicator brushes 17 which, at the loading zone 14, receive or pick up mascara fluid as the actuator is operated, for travel indicated by arrow 18 away from body 11a and toward zone 19 exposed to the exterior, for application to the user's eye lashes 20, as the user manually manipulates the hand held container body 11a. Belt travel or endwise displacement is guided by elongated guide means or structures indicated generally at 21FIG. 8 shows belt drive gear 22 rotatable about transverse axis 22a, in response to rotation of the actuator 15, about longitudinal axis 22b. Gear teeth 24 engage internal gear teeth 25 integral with the belt, to drive the belt. Gear teeth 34 on the actuator sleeve 35 engage gear teeth 36 on the spindle 27. Spindle 27 is rotatable about axis 22a.

Accordingly, second gearing is provided to rotate a spindle about a transverse axis 22a in response to actuator rotation about a longitudinal axis; and first gearing is provided to advance the belt longitudinally in response to said spindle rotation. More specifically, first gearing is associated with the spindle to rotate the spindle about a transverse axis 22a as the actuator is manually rotated about a longitudinal axis 22b, and second gearing is associated with the spindle and belt to drive the belt endwise in response to such spindle rotation. Also, the second gearing includes gear teeth 25 on the belt inner side, belt brushes 17 being presented at the belt outer side. Also, the first gearing includes interengageable teeth on an actuator part and extending about said longitudinal axis and the teeth on the spindle.

FIG. 8 shows cup shaped loading zone 14 formed by the actuator, into which the lowermost end portion 16a of the belt 16 dips, to enable bristles or brushes 17 to scoop up liquid mascara to be transported to the eyelash application zone 19, as the belt is advanced endwise and turns 180° in cup 14a. Liquid mascara is proportionally delivered toward the zone 19 as the actuator is rotated, the cup zone 14 forming a 180° turn brush guide. Such actuator rotation also rotates a mascara delivery tube 40, having threaded engagement at 41 with a pusher piston 42 in the container body. As the tube 40 rotates, the piston 42 is driven downwardly in the container body interior, to push mascara into and upwardly in the tube 40, for upwardly supply to the loading zone 14, in a delivery amount proportioned to mascara pick-up by the belt bristles projecting at 17a into the loading zone. FIGS. 7 and 8 also show the actuator rotatable wall 35 having connection at 48 both to wall 39a of cup 14a, and to the threaded tube 40.

FIG. 10 shows a top end wall 51 of the tubular actuator.,

FIG. 19 shows the housing 60 acting as guide means for the driving and driven elements. Elongated portion 60a of the housing extends protecting at one side of the belt, and terminates at 60b to guide the belt extent 16a in an exposed reversing travel path at the end of the belt housing. Lowermost extent 60d of the housing fits adjacently to the upper extent of the
