Description




FIELD OF THE INVENTION




The invention herein relates to a cosmetics container and applicator which can be operated with one hand.




BACKGROUND OF THE INVENTION




Prior art cosmetic containers often are two-piece assemblies. One body piece provides a reservoir for containing the liquid or pasty cosmetics, and the other piece includes a cap with an extending rod and applicator. The rod and applicator are inserted into the reservoir of the body containing the cosmetics and the cap is secured to the body for transportation and storage. The applicator also becomes loaded with cosmetics while in the reservoir, and the cap is removed to withdraw the applicator and then to apply the cosmetics.




If the user is conveniently seated at a makeup table, it is possible to put the container body on the table while the cosmetics applicator is being used. However, the user often holds the container body in one hand and the applicator in the other hand. This can be highly inconvenient, requiring a proverbial third hand, if the user also needs to hold a mirror or a purse or the like while applying the cosmetics.




The cosmetics applied with such containers is often mascara. However, the cosmetics also include other liquid, semi-liquid, pasty or related cosmetics such as lip gloss, concealer, eye shadow and other facial cosmetics.




There have been prior efforts to provide cosmetics containers for one handed operation. However, these efforts have generally not been successful. Some of the containers utilize a drive means which is axially aligned with the applicator rod and brush, resulting in a very long unit, whereas the dimensions of a cosmetics container for one hand operation should be close to those of a conventional one, both for ease of use and compact storage.




However, a major drawback to prior art one hand cosmetics container is their inability to adequately seal the cosmetics against leakage and drying. It is a necessity that the cosmetics be safely contained within a cosmetics container, so that no mess will result if the cosmetics container is carried in a purse. Also, if the cosmetics, and particularly mascara type cosmetics, are exposed to air through an inefficient seal, the cosmetics will not maintain the desired consistency but will instead dry out and become useless.




It is also necessary for a one handed cosmetics container to load the proper amount of cosmetics on the applicator, including any wiping aspects and avoidance of unwanted buildup of cosmetics at the point the applicator is returned to the container.




Accordingly, the art has not provided a satisfactory cosmetics container for one hand operation despite the obvious benefits such a container would achieve.




SUMMARY OF INVENTION




Accordingly, it is the principal object of the invention herein as to provide a cosmetics container for one hand operation.




It is an additional object of the invention herein to provide a cosmetics container for one hand operation which is of convenient shape and size.




It is a further object of the invention herein to provide a cosmetics container for one hand operation which seals the cosmetics against leakage and spoilage between uses.




It is an additional object of the invention herein to provide a mascara container for one hand operation which presents the applicator with a desired amount of cosmetics thereon for application.




It is a still further object of the invention herein to provide a cosmetics container for one hand operation which enhances the useful life of the cosmetics contained therein.




The invention herein relates to a cosmetics container, for facial cosmetics including mascara, that can be operated with one hand. According to broad aspects of the invention, an applicator is fully retracted within a reservoir defined by a cosmetics container body, with the body defining a passage for extending the applicator from the reservoir. A wiper is positioned at end of the body, having a wiper opening generally aligned with the passage. The cosmetics applicator including a rod is slidably supported within the reservoir for movement between a retracted loading position within the reservoir and a use position with the applicator extending through the passage. Drive means are mounted to the body, the drive means having a knob presented on the exterior of the body for one handed manipulation and a drive belt extending into the reservoir and connecting with the applicator. A cover is also connected with the drive means. Operation of the knob in a first direction removes the cover from sealing the passage and propels the applicator from the reservoir. Operating the knob in another direction retracts the applicator into the reservoir and closes the cover.




According to one aspect of the invention, the applicator is a mascara brush.




According to additional aspects of the invention, the knob, drive belt and cover are slidingly mounted on the body of the cosmetics container. The knob is mounted on a side of the elongated body, and one of the cover or drive belt are guided in a U-shaped path so that the drive belt and cover move in opposite directions relative to the passage. Thus, the cover moves away from the passage as the drive belt propels the applicator toward and through the passage.




According to further aspects of the invention, the wiper has a resilient rim and the cover, in its closed position, is supported against the resilient rim by the container body to provide a good seal. The resilient wiper is deformed to insure a good seal, and in more particular aspects the cover slides into its closed position and deformingly engages the rim of the wiper to achieve sealing relationship therewith, and the rim has a sealing bead to enhance the seal.




In accordance with other aspects of the invention, the container body includes an inner body defining the reservoir and mounting the wiper, and an outer body, with at least a portion of the cover positioned and guided between the inner body and outer body. The outer body is configured to guide the cover into sealing engagement with the wiper. According to more detailed aspects, the knob is presented on the exterior of the outer body and includes a stem extending through a slot in the outer body to connect with the cover and drive belt.




According to additional aspects of the invention, an umbrella pump is disposed within the reservoir and is driven upwardly and downwardly with the applicator. The umbrella pump positions, mixes and distributes the cosmetics within the body for fully loading the applicator and maintaining the cosmetics in good condition.




According to further aspects of the invention, the umbrella pump is carried toward the wiper with an outwardly propelled applicator rod to fill a loading space adjacent the wiper with cosmetics, and the umbrella pump flexibly deforms to release cosmetics in excess of the loading space volume. The excess cosmetics are deposited generally along the walls of the reservoir, below the loading space. As the applicator is retracted, the umbrella pump is carried downwardly in the reservoir and wipes the released cosmetics toward the bottom of the reservoir. As the umbrella pump approaches its lowest position, it flexibly deforms to release the wiped cosmetics and reposition them on the upper side of the umbrella pump, where the cosmetics are available in a pump space for carrying to the loading space on the next deployment of the applicator.




In accordance with additional aspects of the invention, the umbrella pump is partially supported on spaced-apart radial fins extending from the applicator rod. The radial fins extend to the walls of the inner body defining the reservoir, and also support the applicator for sliding motion within the reservoir.




Other aspects and features of the invention will in part appear from the following description of the preferred embodiments and claims, taken together with the drawings.

DETAILED DESCRIPTION OF THE INVENTION




With reference to

FIGS. 1A

,


1


B and


1


C, a cosmetics container


10


is schematically shown which illustrates the invention herein. The cosmetics container


10


has a body


12


including a reservoir


14


filled with mascara. An exit passage


24


is defined at the end of the body. A combination wiper and seal


16


is provided at the outlet passage end of the container with its wiper opening generally aligned with the exit passage


24


. The wiper


16


is shown schematically in

FIGS. 1A

,


1


B and


1


C, and is shown in more detail in

FIGS. 2 and 4

. An applicator including applicator brush


18


mounted on an applicator rod


20


is slidably mounted within the reservoir


14


. A flexible drive belt


22


extends from the lower end of the applicator rod along the lower end and side of the body


12


and has a cover portion generally indicated at


23


covering the exit passage


24


at the upper end of the body


12


. A knob


26


, or alternatively a thumb wheel, is provided for driving the belt


22


.




With reference to

FIG. 1B

, the knob


26


has been pulled downwardly, driving the applicator rod


20


and applicator brush


18


upwardly through the wiper


16


and the exit passage


24


. It will be appreciated that as the drive belt


22


is driven to push up the applicator rod, it retracts the cover portion


23


from covering the exit passage


24


at the upper end of the body


12


, providing clearance for the brush


18


to exit. This may be done by providing a slotted opening in the cover portion of the belt or by withdrawing it altogether. In

FIG. 1C

, the knob


26


is in its lowermost position and the applicator brush


18


is in its uppermost use position for application of mascara.




The applicator rod


20


has a flexible radially extending umbrella seal or pump


30


attached thereto. As the applicator moves up and down, the umbrella pump


30


mixes and distributes the mascara in the reservoir


14


body


12


, positioning the mascara to fully load the mascara brush


19


when the mascara brush is withdrawn into the container. The mixing provided by the umbrella pump is also advantageous to maintaining the mascara product in good condition.




With reference to

FIGS. 2-5

, more detailed construction of the mascara container


10


is illustrated. The body


12


defines the upper exit passage


24


, adjacent to which the wiper and seal component


16


is positioned. The wiper has wiper opening


17


, generally aligned with the passage


24


. The opening


17


through wiper


16


defines a wiper orifice


34


for removing excess mascara from the applicator brush


18


.




The cover portion


23


of drive belt


22


is shown extending across the exit passage


24


, for sealing it. With reference to

FIG. 4

, the sealing aspect of the wiper


16


is shown in more detail, wherein the wiper


16


defines a peripheral sealing bead


32


which engages the underside of the cover portion


23


of drive belt


22


when the cover is closed. The sealing bead


32


surrounds the wiper opening


17


.




The drive belt


22


is operated by the knob


26


, and the drive belt is supported in a 180° U-turn at the lower end of the body


12


and is sealingly inserted into the reservoir


14


where it engages a radially finned slide base


36


of the applicator rod


20


. The slide base


36


supports the umbrella pump


30


as the applicator rod


20


and brush


18


are extended upwardly in order to pump mascara toward the upper portion of the product cavity or reservoir


14


. The umbrella pump flexes to bypass mascara when the upper portion of the reservoir is full. The periphery of the umbrella pump also lifts off the slide base


36


as the rod is pulled downwardly, leaving a trail of mascara along the walls of the product cavity for reloading the brush: This action also mixes and maintains the mascara.




With particular reference to

FIG. 5

, the lower structure of the container


10


is illustrated. The reservoir


14


is provided with an end plug


40


having a fill port


42


and a curved surface


44


partially supporting and guiding the drive belt


22


. A slot


28


admits the drive belt


22


for driving the slide base


36


and applicator brush


18


. A bottom cap


46


includes a plug


48


for the fill port


42


and additional guide geometry for the drive belt


22


.




The drive belt can also be provided in the form of a thinner drive shaft extending from a wider cover portion


23


providing a cover and seal over the exit passage


24


of the container.




Although the cosmetics container


10


has been described in connection with mascara cosmetics, the invention is fully intended to apply to containers of similar concept and structure adapted for use with lip gloss, concealer, eye shadow and other liquid, semi-liquid and pasty cosmetics products that are applied with a brush, foam pad, flocked member or other suitable applicator.

60


.




It will be appreciated that when the knob


72


is in its uppermost position, the cover


74


closes and seals the passage


60


, and the drive belt cable


140


pulls the applicator


64


to its lowermost position in the reservoir. When the drive knob


72


is pulled downwardly along the outer body


56


, the cover


74


is pulled away from the passage


60


, at the same time the applicator


64


is propelled outwardly through the uncovered passage


60


from the reservoir


58


.




The cosmetics container


50


also includes an umbrella pump


76


, which is mounted on applicator rod


125


between slide


126


and its fins


127


-


130


, and flange


136


. Details of the umbrella pump


76


are illustrated in

FIGS. 15-20

. The umbrella pump


76


is shaped to generally conform to the inside of reservoir


58


, including a notch


186


accommodating ribs


86


, a straight edge


188


that lies adjacent at wall


84


, and curved side pods


190


,


192


that lie adjacent the curved wall portions of the reservoir and are cup shaped to spread and carry mascara or other cosmetics upwardly. The umbrella pump is also fabricated of flexible synthetic rubber material, preferably Buna-N.




With reference to

FIGS. 17 and 18

, the umbrella pump


76


assumes the position shown, with the side pods


190


and


192


disposed generally upwardly, during a downward movement of the applicator


64


, and is restrained on applicator rod


125


by the flange


136


. The umbrella pump may also assume foregoing position on an upward stroke, without influence of cosmetics, or when the cosmetics are not viscous and is not placing significant force on the umbrella pump


76


.




With reference to

FIG. 19

, the umbrella is shown as it usually appears in an upward stroke of the applicator


64


. The side pods


190


and


192


rub against the side walls of the reservoir, which tends to turn the umbrella “inside out” into the flattened position supported on the radial fins


127


-


130


. The pods


190


,


192


are nevertheless deployed to carry mascara upwardly.




However, the mascara is viscous, and does resist being carried and therefor exerts pressure with respect to the umbrella pump, at which point the umbrella pump sags inwardly from the walls of the reservoir, permitting mascara to leak past it. In the downward stroke position shown in

FIG. 17

, the umbrella pump merely bends inwardly toward the applicator rod


25


, permitting mascara to bleed by it. In the upward stroke shown in

FIGS. 19 and 20

, the umbrella pump


76


is supported on the fins


127


-


130


, but sags downwardly and inwardly between the fins as illustrated at


194


-


197


. This permits mascara to bleed past the umbrella pump


76


on the upward stroke of the applicator


64


.




The operation of the cosmetics container


50


, and of the umbrella pump


76


in particular, is illustrated in

FIGS. 21-26

. For clarity, only the inner body


56


, wiper


62


, applicator


64


and umbrella pump


76


are illustrated in

FIGS. 21-26

, it being understood that the drive means


70


extends and retracts the applicator


64


in the manner discussed above. The end cap


112


is shown schematically as a bottom closure of the reservoir


58


, also for clarity and ease of illustration.




In

FIGS. 21-26

, the reservoir


58


has been filled with an appropriate volume of mascara which may comprise approximately one-third to one-half of the volume. Filling is accomplished by extending a small conduit through the fill tube


122


and flowing the mascara into the reservoir. The fill conduit may easily extend past the umbrella pump


76


, due to its flexibility. After filling, the fill plug


168


closes off the fill tube


122


.




With reference to

FIG. 21

, the applicator


64


is illustrated in its lower or retracted position. The distribution of the mascara


80


within the reservoir


58


illustrated in the drawing is achieved after several operating cycles of the applicator between its retracted and extended use position. It will be understood that the mascara


80


is not positioned within the reservoir in any particular manner by the filling process, and as will become more clear, the umbrella pump


76


operates to achieve the desired deployment.




When the applicator


64


is in its retracted position, the mascara


80


is substantially divided into a first portion


80




a


in a loading space


200


at the upper end of the inner body


56


, adjacent the wiper


62


. The loading space


200


surrounds at least a substantial portion of the mascara brush


66


. The tip


67


of the mascara brush is preferably positioned closely adjacent the wiper diaphragm


102


so as to partially block the wiper orifice


104


. When the mascara or other cosmetics is relatively viscous, this will substantially retain the mascara in the reservoir


58


between uses of the cosmetics container


50


. An additional portion


80




b


of the mascara


80


is located in a pump space


205


at the lower end of the inner body


56


, above the umbrella pump


76


. Some of the mascara is below the umbrella pump


76


, adjacent the fins


127


-


130


.




With reference to

FIG. 22

, the applicator is shown partially extended through the wiper


62


, exposing the mascara brush


66


. It will be appreciated that the upper portion of the mascara brush


66


was positioned in cosmetics


80




a


in the loading space


200


and the remainder of the mascara brush


66


passes through the loading space in translation from the position shown in

FIG. 21

to the position shown in

FIG. 22

, whereby the mascara brush


66


is appropriately loaded with mascara for application to eyelashes. The wiper adjusts the amount of mascara on the extended brush, in accordance with usual mascara container practice. However, the wiper operates very effectively because the brush is uniformly loaded before being extended. With continued reference to

FIG. 22

, the umbrella pump


76


carries a substantial part of the mascara


80




b


upwardly from the pump space


205


. Because the umbrella pump


76


does not perfectly seal with the sides of the reservoir


58


and because it is flexible, a portion of the mascara


80




c


bleeds past and trails behind the umbrella pump


76


along the wall of the reservoir


58


.




With reference to

FIG. 23

, the applicator


65


is approaching its outermost extended position. Inside the reservoir


58


, the mascara


80




b


carried upwardly by the umbrella pump


76


joins the mascara


80




a


in the loading space


200


. Because the applicator rod


125


is in sealing engagement with the wiper diaphragm


102


, the loading space


200


is essentially filled and the excess volume of mascara leaks by the flexible umbrella pump


76


and is deposited on the inside walls of the reservoir, as indicated at


80




c


. The umbrella pump assumes the position shown in

FIG. 20

to permit the excess mascara to bleed past the edges of the umbrella pump


76


. The merger of the cosmetics


80




b


being carried upwardly with the mascara


80




a


already in the loading zone mixes the two portions of mascara


80


and stirs and agitates the mascara


80


, which is helpful in keeping the mascara fresh for use.




With reference to

FIG. 24

, the applicator


66


is shown at the initial stage of retraction from the furthest extended position. Thus, the umbrella pump


76


reverts to the position shown in

FIG. 17

, in preparation for collecting the mascara


80




c


left on the side walls of the reservoir during its downward stroke.




With reference to

FIG. 25

, the applicator is shown partly retracted, with the brush re-entering the reservoir through the wiper orifice. The umbrella pump


76


is correspondingly retracted into the reservoir


25


, leaving a portion of mascara


80




a


in the loading space


200


. The umbrella pump


76


has substantially wiped the mascara


80




c


from the side walls of the reservoir between the loading space


200


and the umbrella pump


76


, collecting this mascara below the umbrella pump and surrounding the slide


126


.




As the applicator


64


approaches its lower most position shown in

FIG. 26

, there is insufficient space surrounding the slide


126


to accommodate the mascara wiped from the walls, and the umbrella pump flexes to permit the mascara to leak by and occupy the pump space


205


, that mascara now being shown as the portion


80




b


. It will appreciated that there is substantial mixing and agitating of the mascara as it bleeds by the umbrella pump


76


to fill the pump space


205


. At the upper end of the reservoir, the applicator brush


66


is re-immersed in the mascara


80




a


in the loading space


200


. Of course, as discussed above, the cover


74


is deployed across the exit passage


60


when the applicator is retracted, sealing the mascara from leakage and drying between uses.




Of course, all of this positioning and mixing of mascara is occurring in normal use of the cosmetics container


50


. The user merely slides the drive knob


72


downwardly with one hand, and is presented with an applicator properly loaded with mascara or other cosmetics, and may recharge the brush by additional one hand operation of the knob


150


. When the knob is left up, the container is closed and sealed.




Accordingly, cosmetics containers admirably fulfilling the objects of the invention herein have been described. It will be appreciated by those skilled in the art the mascara containers described are preferred embodiments and that various changes may be made without departing from the spirit and the scope of the invention, which is limited only by the following claims.
