A cosmetic applicator for a cosmetic agent includes a capless housing; a seal for sealing the housing from an exterior; a seal opener for opening the seal to prevent damage to the cosmetic agent; and a control for manipulating the seal opener to open the seal and advancing the cosmetic agent is advanced from a stored position to an advanced position beyond the seal.

BACKGROUND OF THE INVENTION

The present invention relates to applicators for applying a product to the body of a consumer, in particular to cosmetic applicators having an internal sealing structure.

DISCUSSION OF THE PRIOR ART

Cosmetic applicators include a cosmetic agent, such as lip gloss, mascara, lip liner, concealer, foundation, eye shadow, and eyeliner, etc. To prevent the cosmetic agent from drying out or transferring the agent to unintended objects and surfaces, cosmetic applicators include a cap. Users of such capped applicators run the risk certain unintended consequences when the cap is displaced from the applicator or altogether is lost. For example, when the cap of a capped applicator is displaced, the cosmetic agent in the applicator begins to dry out and if left unattended becomes unusable. Similarly, the cosmetic agent may absorb odors from its surroundings.

Other consequences may be worse. The cosmetic agent may permanently mar the space where the capped applicator was stored or other items stored alongside the capped applicator. When such a storage location is the inside of an expensive purse or bag, the consequence may be more than just incidental—marring the purse or bag, marking identification documents; credit cards.

To guard against the latter, capped applicators are designed so that the cosmetic agent is stored retracted in a housing and is recessed from the peripheral top edge of the housing. However, this attempt is typically insufficient since protrusions in other items contact the cosmetic agent, which is then easily transferred.

This arrangement also provides an unappealing and sometimes counterintuitive user experience. To apply the cosmetic, the user must remove the cap, lay the cap down or hold it in one hand, and then manipulate the cosmetic applicator to advance the cosmetic agent into position to apply the agent. Once the agent is applied, the user must then reverse the cumbersome procedure.

A need therefore exists for a simpler and easier to use cosmetic applicator that also avoids the known shortcomings of capped applicators.

SUMMARY OF THE INVENTION

The need for a cosmetic applicator that is simpler and easier to use and that avoids the known shortcomings of capped applicators is met with the present invention. Therein, a capless cosmetic applicator is taught. Such an applicator includes a housing and a seal, which made of a pliable material. In a closed state, the housing and seal protects the cosmetic agent from the environment, i.e., the ambient conditions, to preserve the quality of the cosmetic agent.

The housing includes an ergonomic design and functionality that is particularly intuitive. Easy to manipulate controls permit the cosmetic agent to be advanced from the housing, past the seal into a position to be applied to the body of the user.

In a first embodiment, a slide assembly is provided that includes a user actuated button. The button advances a gear, i.e. pinion, and a pair of opposed racks to advance a carrier of the cosmetic agent. A seal opener is provided to protect the cosmetic agent from damage from the self-closing seal.

In a second embodiment, an actuator ring is provided that differentially advances the cosmetic agent via a rotational movement. A seal opener is also provided to protect the cosmetic agent from the self-closing seal.

Spring30is fitted at one end over carrier-spring pin20hand the other end over mounting pin28aof the button return lever to bias the carrier and button return lever against each other.

FIGS. 14a-14gare, respectively, a front perspective view, a rear perspective view, a front view, a top view, a bottom view, and a right side view of the bottom cap32in accordance with one embodiment of the present invention. The left-side view is identical to the right-side view.FIG. 14gis a cross-sectional view of bottom cap32taken along line A-A ofFIG. 14c. Bottom cap32is preferably made of acrylonitrile butadiene styrene or like material.

Bottom cap32is preferably formed to have a substantially tapered cylindrical shape that is wider at an open end than at a closed end, which forms the distal end of capless cosmetic applicator10. The tapered shape preferably continues the smooth ergonomic lines from the housing.

One or more assembly notches32aadvantageously shaped for locking are provided proximal to the open end. The assembly notches engage left-hand housing assembly indents16dand right-hand housing assembly indents18dprovided in the respective bottom body portion16c,18cto lock the two housing halves16,18together and form housing assembly.

To assist in locking left-hand housing16and right-hand housing18together, a circumferential lip32bis formed in the interior surface of bottom cap32. Main body portion16a,18aof each housing half16and18rest on lip32b, while the lower body portions16c,18cextend at least partially, or preferably, to the closed end of bottom cap32.

FIGS. 15a-15gare, respectively, a front perspective view, a rear perspective view, a front view, a top view, a bottom view, and a right side view of the top cap34in accordance with one embodiment of the present invention. The left-side view is identical to the right-side view.FIG. 15gis a cross-sectional view of top cap34taken along line A-A ofFIG. 15c. Top cap34is preferably made of acrylonitrile butadiene styrene or like material.

Top cap34is preferably formed to have a substantially tapered cylindrical shape that is narrower at a first open end34a, which defines the proximal end of capless cosmetic applicator10when in the closed stated and for user safety is softened by removing any sharp edges, than a second open end34b. The tapered shape preferably continues the smooth ergonomic lines from the housing.

One or more assembly notches34cadvantageously shaped for locking are provided proximal to the open end. The assembly notches engage left-hand housing assembly indents16dand assembly indents18dprovided in the respective top body portion16b,18bto lock the two housing halves16,18together and form housing assembly.

When a user intends to access a retracted cosmetic agent14from a capless cosmetic applicator10in a closed state, the user depresses button24and slides the button to the proximal end of capless cosmetic applicator10.

The button engages carrier advance gear26. In turn, carrier advance gear26begins turning against the rack on the carrier and the housing. Since the user is restraining the housing by holding the housing in the user's hand, the carrier moves differentially with respect to the housing.

The carrier pins are initially disposed in a locking position in the seal opener restriction22bof the seal opener guides. Thus, the user initially must apply a slightly greater force, which the user can interpret as a confirmation that the internal mechanisms of the capless cosmetic applicator are working in response to the user. In the case of the reverse action of retracting cosmetic agent14, the locking action can serve as confirmation of secure positioning. It further serves to provide an initial resistance to inadvertent movement of the slider assembly.

Depressing button24causes the gear to push carrier20to the center of the central cavity, while the hinged legs24cto bias the carrier to prevent rotation of the carrier. As the carrier is pushed from its rest position, it causes spring30to compress.

Turning of carrier advance gear26causes the differential movement of the carrier20moves relative to housing assembly. Since the carrier has not cleared the restriction in guides22a, the carrier and seal opener move in unsion longitudinally towards the proximal end of capless cosmetic applicator10. Also in unison, button return lever28moves in the same longitudinal direction by sliding on the ramps16k,18k.

When seal opener rim22ccontacts the lip formed from left-hand housing upper lip16nand right-hand housing upper lip18n, the seal opener22has reached its travel limit with respect to housing assembly, and the carrier pins20dnow clear the restriction of guides22a. The seal opener will have parted the seal and, because the seal opener is sized to extend beyond the limit of the opened seal, the seal opener provided a sleeved protection for the cosmetic agent.

Once the seal opener rim22chas contacted the lip formed from left-hand housing upper lip16nand right-hand housing upper lip18, carrier20is able to advance beyond the restriction22bby the user applied force, as explained above. Thus, the limit of travel for the carrier is limited by the proximal end of guides22a.

The user can stop the advancement of the cosmetic agent at any point, such as when sufficient length of cosmetic agent14has been made available, by releasing button24. therein, teeth24dwill engage ratchets16h,18hand hold the carrier in position. Because button return lever28and the carrier20exert a biasing force against the carrier, the button is returned to a user accessible position and teeth24dare biased against ratchets16h,18h.

When the user wishes to store cosmetic agent14in capless cosmetic applicator10, the user depressed button24causing the differential movement of the carrier relative to the housing. Thus, carrier20retracts with respect to sleeve opener22that continues to part seal19until carrier pins20dcontact restrictions22band exert a downward force on the seal opener causing both to continue in a longitudinal direction toward the distal end.

The seal opener will continue to travel until the underside of rim22cengages the top edge of guides16i,18iat which time the seal opener will cease longitudinal travel but the carrier will continue travel. The carrier pins20dwill, thus, on user applied force move through the restrictions and when the pins reach the distal end of guides22a, the carrier will cease movement and the cosmetic agent is store. When the user releases the button, the biasing force of the spring and the lever button resting in housing notch16l,18lwill push the button into a forward position available for the next use.

With respect toFIGS. 16-24, in a second embodiment of the present invention of a capless cosmetic applicator, an actuator ring124moves a cosmetic agent in a longitudinal direction with respect to a housing, i.e. container body112through a seal, i.e. overmolding122from a retracted position into a selectable advanced position where the user can apply the cosmetic agent to the user's body or moves the cosmetic agent from such a position to a retracted position.

FIGS. 16a-16dare, respectively, a front perspective view and a rear perspective view of a capless cosmetic applicator110in accordance with one embodiment of the present invention.FIGS. 16aand16billustrate capless cosmetic applicator110in a closed state. In a closed state, a cosmetic agent provided in the capless cosmetic applicator110is in a retracted state. As is evident from the design, capless cosmetic applicator110provides an ergonomic, transportable cosmetic applicator.

FIGS. 16cand16dillustrate capless cosmetic applicator110in an open position. Therein, a user has used an actuator ring to advance a cosmetic agent114in position to apply cosmetic agent114to the body of the user. The actuator ring may also be used to retract cosmetic agent114into capless cosmetic applicator110and store it for the aforementioned advantageous reasons.

Overmolding122may be made of a thermoplastic elastomer or the like and is configured as a crown having a flat top surface122aand a plurality of valleys122b. Two intersecting cuts122care made in the surface122aand effectively create four quadrants that are defined by the angled valley122bthat creates a biasing that pushes the quadrants together to form a self-closing sealing structure to seal the interior of cosmetic applicator110from the ambient air.

FIGS. 23a-23fare respectively, a front perspective view, a rear perspective view, a front view, a top view, and a bottom view of an actuating ring124in accordance with one embodiment of the present invention.FIG. 23fis a cross-sectional view taken along line A-A ofFIG. 23c. Actuating ring124preferably is an annulus and is made of acrylonitrile butadiene styrene, styreneacrylonitrile, or the like.

Actuating ring124includes an outer surface124athat is ergonomically designed and includes one or more finger knurls124b. The interior surface of actuating ring124includes an annular container body groove124cspaced from an annular cap groove124d. Each groove designed to press fit a corresponding portion of the container body or the cap in the respective groove. For example, container body groove124creceives container body rim112b, more particularly the annular sloped surface112e. The rim is able to move freely with the respective groove because the groove is sized slightly larger than the rim.

Spaced between the grooves124cand124dis an annular portion that includes one or more keys124e. Preferably, the number of keys124ematches the number of keyways120eand each key is sized to engage the keyways to turn sleeve120and in turn advance the seal opener through the overmolding seal and the cosmetic agent via the carrier through the seal.

FIGS. 24a-24fare, respectively, a front perspective view, a rear perspective view, a front view, a top view, a bottom view, and a right-side view of a cap126in accordance with one embodiment of the present invention. Therein, cap126may be made from acrylonitrile butadiene styrene, styreneacrylonitrile, or the like.

FIGS. 24gand24hare, respectively, a cross-sectional view taken at line A-A ofFIG. 24cand a detail view taken of area B-B ofFIG. 24f.

Cap126is preferably formed to have a substantially tapered cylindrical shape that is narrower at a first open end126a, which defines the proximal end of capless cosmetic applicator110when in the closed stated and for user safety is softened by removing any sharp edges, than a second open end126b. The tapered shape preferably continues the smooth ergonomic lines from the housing.

Cap126includes a rim126that may be similar in structure to rim126a. Therein, rim126acharacterized by a recessed annular surface126b, an annular plinth126c, and an annular sloped surface112d. Sloped surface112dpreferably has a cant of 35 degrees with respect to a longitudinal centerline through the cap.

Rim126ais sized to fit into a groove provided in the interior surface of actuating ring124so that the cap turns freely with respect to the actuating ring.

When a user intends access a retracted cosmetic agent114from a capless cosmetic applicator110in a closed state, the user turns actuating ring124in a right-hand direction. Therein, the actuating ring will turn freely with respect to the container body and the top cap. However, since the keys in the actuating ring will engage the keyway in the sleeve, the sleeve will turn in unison with the actuating ring causing the carrier pins to turn in helical guides120avia centrifugal action. Therein, this will cause the pins disposed in the guides to push against the restrictions in the sleeve opener guides and move the seal opener longitudinally with respect to capless cosmetic applicator110.

Seal opener116will continue to travel longitudinally until it engages the bottom peripheral edge120fof the sleeve. At that time, the seal opener will have parted the seal and will prevent the softer cosmetic agent from being damaged by the seal.

Even though the longitudinal movement of the seal opener has stopped, it continues to be capable of rotational movement. At that time, the user-applied force will overcome the restriction in guides116aand the carrier will continue rotation. The carrier's rotary movement will cause the seal opener's rotation and the carrier will advance longitudinally by turning in helical guides120awhile the seal opener maintains the seal in an open position.

When carrier pins118dreach the proximal end of guides120a, the longitudinal movement of the carrier ceases and the cosmetic agent is in a maximum extended position. Of course, the user could at any point that the cosmetic agent is in an extended position that is satisfactory to the user cease turning the actuating ring and stop the longitudinal travel of the carrier.

To store the cosmetic agent, the user needs to turn the actuating ring in a reverse direction. At that time, the carrier will turn until it contacts the restriction at which time the seal opener moves longitudinally to the distal end and the seal closes. When the carrier pins overcome the restriction in guides120aand lock, the cosmetic agent is stored in the maximum closed state.

While the invention has been described in conjunction with specific embodiments, it is to be understood that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description.
