Abstract
A cosmetic container precludes exposure of the cosmetic within the container to the environment outside the container, even during application of the cosmetic, because, as the applicator head is used to apply the cosmetic to an intended wearer, other portions of the applicator preclude exposure of the cosmetic remaining within the container to the environment.
Description




BACKGROUND OF THE INVENTION




The present invention relates to an airtight magnetic applicator system and more particularly to such a system embodied in a cosmetic container.




Many cosmetics are in the form of a flowable powder (e.g., face powder, foundation, etc.) or a liquid containing a volatile component such as a volatile solvent (e.g., nail polish, some lipsticks and lip glosses, etc.). Such cosmetics should be stored in an airtight container to prevent loss of the powder, liquid and especially the volatile component (to preclude drying out of the cosmetic). This is not a particular problem while the cosmetic is being stored in the container with the cover thereon to provide an airtight enclosure. The problem arises once the cover is removed from the container so that the cosmetic may be removed from the container and applied to the intended wearer.




Thus, if removal of the cover from the container leaves too small an opening, it becomes difficult to remove the desired quantity of the cosmetic from the container. If removal of the cover from the container leaves too large an opening, then the exposure of the cosmetic to the atmosphere through the aperture is excessive, thereby leading either to contamination of the atmosphere outside the container or to loss or drying out of the cosmetic within the container. While the removal of the cosmetic from the container may be accomplished in a relatively brief time, typically the application of the cosmetic to the intended wearer is a substantially more lengthy process during which the cosmetic within the container and the atmosphere are in communication. Such application times may be considerable in the case of carefully applied mascara, lipstick, nail polish, and the like. The applicator is typically a brush, small scoop, glass rod, or the like projecting outwardly from the removable cover so that the applicator can be manipulated by the user employing the cover as a handle and so that the applicator head is maintained in or exposed to the cosmetic during storage. Such an applicator is part of or fixedly secured to the cover so that the cover cannot be replaced on the container (to resume the airtight integrity of the container) until application of the cosmetic has been completed.




The advantage of such an applicator/cover configuration is that the applicator head is typically in contact with the cosmetic during storage so that the residual cosmetic on the applicator head from the previous use thereof does not dry out. This is especially important in case of a liquid cosmetic containing a volatile solvent because, once the volatile solvent evaporates from the cosmetic on the applicator head, clumps of dry cosmetic are created on the applicator head and these may be resistant to resolublization by the solvent.




Accordingly, it is an object of the present invention to provide a cosmetic container wherein in one preferred embodiment the cosmetic within the container is not exposed to the environment outside the container even during application of the cosmetic.




Another object is to provide such a container wherein in one preferred embodiment the applicator head is in fluid communication with the cosmetic when the cover is on the container.




A further object is to provide such a container wherein in one preferred embodiment the applicator head may be used to apply the cosmetic to an intended wearer while other portions of the applicator preclude exposure of the cosmetic remaining within the container to the environment.




It is another object of the present invention to provide such a container which in one preferred embodiment is simple and inexpensive to produce, easy to use and maintain, and compact and attractive in configuration.




SUMMARY OF THE INVENTION




It has now been found that the above and related objects of the present invention are obtained in a cosmetic container comprising a longitudinally extending reservoir for a flowable cosmetic, the reservoir having a closed end, an open end and a magnetically-transmissive sidewall. A removable cover is provided for closing the reservoir open end, the reservoir and the cover cooperatively defining an airtight enclosure for the cosmetic. The container includes an exterior magnet and means for maintaining the exterior magnet on the exterior of the reservoir sidewall and for moving the exterior magnet between a first position adjacent the reservoir closed end and a second position adjacent the reservoir open end. A longitudinally extending applicator defines a head for transferring the cosmetic from the reservoir interior through the reservoir open end, a base carrying an interior magnet responsive to the exterior magnet for longitudinal movement therewith, and a stem connecting the head and the base such that, when the head is substantially aligned with a central longitudinal axis of the reservoir, the interior magnet is closely adjacent the interior of the reservoir sidewall and magnetically coupled with the exterior magnet for longitudinal movement therewith as a unit. Means are provided for maintaining the applicator head in substantial alignment with the central longitudinal axis of the reservoir.




Preferably the reservoir is a hollow cylinder formed of extruded glass having a closed bottom and an open top, the reservoir sidewall being of constant thickness below the open end.




In a first preferred embodiment, the container additionally includes (i) means for maintaining the applicator head in fluid communication with the cosmetic while the cover closes the reservoir open end, (ii) means for applying the cosmetic to the applicator head as the applicator head moves upwardly through the reservoir open end, and (iii) means for sealing the reservoir open end about the applicator while the applicator head is outside of the reservoir, thereby to preclude atmospheric exposure of the cosmetic within the reservoir. The sealing means seals the reservoir open end about the applicator head. Where the cosmetic includes a volatile solvent, the alignment maintaining means also maintains the applicator head in gaseous communication with the volatile solvent. The alignment maintaining means is preferably substantially disposed within the reservoir open end.




In a second preferred embodiment, the applicator stem is substantially rigid and connects the base and the head in an offset relationship. The base extends a first distance to one side of a longitudinal axis through the applicator, and the head extends a second distance to an opposite side of the longitudinal axis. Preferably the first and second distances combined are greater than the inner diameter of the reservoir open end, and the base only snugly passes through the reservoir open end.




In a third preferred embodiment, the container additionally includes a stationary flow controller extending through the reservoir open end in fluidtight relationship. The interior of the flow controller defines a central flow channel having a fluidtight sidewall, and the flow controller includes flow restricting means to limit the flow of cosmetic from the reservoir into the central flow channel. In this embodiment, preferably the applicator has a ferrule intermediate the stem and head thereof. The ferrule is configured and dimensioned to fit snugly into the central flow channel for reciprocating sliding movement relative thereto. The ferrule, cooperatively with the central flow channel, (i) precludes cosmetic flow from the reservoir into the central flow channel when the applicator head extends outwardly from the central flow channel, (ii) limits cosmetic flow from the reservoir into the central flow channel when the applicator head is totally within the central flow channel, and (iii) pumps cosmetic from the reservoir into the central flow channel and onto the applicator head as the applicator head is being extended outwardly from the central flow channel.




To summarize, the reservoir is a hollow cylinder of extruded glass having a closed bottom and an open top, and the reservoir sidewall is of constant thickness below the open top. Preferably the base extends a first distance to one side of a longitudinal axis through the applicator, and the head extends a second distance to an opposite side of the longitudinal axis, the first and second distances combined being greater than the inner diameter of the reservoir open end, and the base only snugly passing through the reservoir open end. The alignment maintaining means is substantially disposed within the reservoir open top and maintains the applicator head in gaseous communication with a volatile solvent in the cosmetic. The container additionally includes (i) means for applying the cosmetic to the applicator head as the applicator head moves upwardly through the reservoir open top, (ii) means for sealing the reservoir open top about the applicator while the applicator head is outside of the reservoir, thereby to preclude atmospheric exposure of the cosmetic within the reservoir, the sealing means sealing the reservoir open top about the applicator head, and (iii) means for maintaining the applicator head in fluid communication with the cosmetic while the cover closes the reservoir open top. The container preferably additionally includes a stationary flow controller and a ferrule. The exterior of the flow controller extends through the reservoir open end in fluidtight relationship therewith, the interior of the flow controller defining a central flow channel having a fluidtight sidewall and including flow restricting means to limit the flow of cosmetic from the reservoir into the central flow channel. The ferrule is mounted on the applicator intermediate the stem and head thereof, the ferrule being configured and dimensioned to fit snugly into the central flow channel for reciprocating sliding movement relative thereto. The ferrule is operative, cooperatively with the central flow channel, (i) to preclude cosmetic flow from the reservoir into the central flow channel when the applicator head extends outwardly from the central flow channel, (ii) to limit cosmetic flow from the reservoir into the central flow channel when the applicator head is totally within the central flow channel, and (iii) to pump cosmetic from the reservoir into the central flow channel and onto the applicator head as the applicator head is being extended outwardly from the central flow channel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring now to the drawing, and in particular to

FIG. 1A

thereof, therein illustrated is a cosmetic container according to the present invention, generally designated by the reference numeral


10


. In its basic aspects, the container comprises a longitudinally extending reservoir, generally designated


12


, the reservoir


12


having a closed end


14


, an open end


16


, and a magnetically-transmissive sidewall


18


connecting the ends


14


,


16


. A sidewall neck


19


, preferably of diminished diameter relative to the remainder of sidewall


18


, connects the remainder of the sidewall


18


and the open end


16


.




The reservoir


12


is preferably a hollow cylinder formed of extruded glass or plastic having a closed bottom end


14


and an open top end


16


. The reservoir sidewall


18


is thin and of constant thickness for most of its length below the neck


19


. The use of an extrusion process for the formation of the reservoir is not only economical but facilitates obtaining the desired constant thickness of the reservoir sidewall. However an injection molding, blow molding, or like process may be used, whether with glass or plastic. While the reservoir may be formed of magnetically-transmissive materials other than glass, glass is preferred for its relative inertness to various volatile solvents and the other chemicals which might be found in a cosmetic. A preferred solvent-resistant plastic is the acrylonitrile polymer available under the trade name BARAX from BT Chemical.




A relatively thin reservoir sidewall


18


is preferred to facilitate magnetic coupling of exterior and interior magnets through the sidewall


18


, as will be explained hereinafter. While preferably the reservoir sidewall


18


is magnetically-transparent and does not interfere at all with the magnetic coupling of the exterior and interior magnets through the sidewall, as a practical matter a material which enables the magnetic coupling of the exterior and interior magnets is acceptable even though it does interfere to a limited degree. Referring now to

FIG. 1B

in particular, a removable cover


20


is provided for closing the reservoir open end


16


, the reservoir


12


and the cover


20


cooperatively defining an airtight enclosure. The removable cover


20


and the neck


19


adjacent the open top end


16


may engage threadedly (as illustrated), frictionally, or the like. Indeed, the cover


20


need not be physically separable from the reservoir


12


so long as it can be “removed” to expose the reservoir open end


16


—e.g., a displacement of the cover


20


from the open end, regardless of whether the cover is simply relocated on the reservoir


12


or actually separated therefrom.




In the context of a cosmetic container


10


, the reservoir


12


contains a flowable cosmetic (not shown) whether it be a liquid or powder, and is especially adapted for containing a flowable liquid cosmetic including a volatile constituent such as a volatile solvent.




Returning now to

FIG. 1A

in particular, means, generally designated


30


, are provided for maintaining an exterior magnet


32


on the exterior of the reservoir sidewall


18


and for moving the exterior magnet


32


between a first position generally adjacent (but typically spaced from) the reservoir closed bottom end


14


and a second position generally adjacent (but typically spaced from) the reservoir open top end


16


. The maintaining means


30


partially wraps snugly around the reservoir sidewall


18


, yet permits relative sliding movement of the maintaining means


30


and exterior magnet


32


along a partial length of the reservoir sidewall


18


. The maintaining means


30


may or may not also permit movement of the exterior magnet


32


circumferentially about the reservoir sidewall


18


. The exterior magnet


32


may be captured by the maintaining means


30


for travel therewith via a frictional fit, a resilient fit, adhesive means, or other conventional means for securing components together for travel as a unit. The outer surface of the maintaining means


30


is configured and dimensioned for easy sliding by a finger of the user in either longitudinal direction and, if desired, may incorporate a clip mechanism to enable the container


10


to be carried in a user's pocket (in an inverted orientation and with the cover


20


in place), much as a conventional pen or mechanical pencil.




A longitudinally extending applicator, generally designated


40


, is also provided. The applicator


40


defines at one end a head


42


for transferring cosmetic from the reservoir interior through the reservoir open end


16


(after removal of the cover


20


). The head


42


is illustrated as a longitudinally extending brush formed of bristles, but could alternatively be a simple spoon-like scoop, a length of smooth glass rod, or a like mechanism suitable for the transport and application of the cosmetic. The applicator


40


defines at the other end a base


44


for carrying an interior magnet


46


. The interior magnet


46


is magnetically coupled to the exterior magnet


32


and responsive to longitudinal movement thereof (and preferably circumferential movement thereof) such that ordinarily the two magnets


32


,


46


move as a unit. The base


44


may extend below the interior magnet


46


to act as a stop on retreat of the applicator head


42


into the reservoir


12


.




The applicator


40


additionally defines a stem


48


connecting the applicator head


42


and the applicator base


44


, preferably in a horizontally offset relationship such that, when the head


42


is substantially aligned with the central longitudinal axis of the reservoir


12


, the interior magnet


46


is closely adjacent (and preferably, as shown, in slidable contact with) the interior of the reservoir sidewall


18


and magnetically coupled with the exterior magnet


32


for movement therewith as a unit. The applicator stem


48


, like the base


44


, is substantially rigid so that upward or downward movement of the interior magnet


46


carried by base


44


results in a corresponding movement of the applicator head


42


.




The applicator


40


further includes means


50


for maintaining the applicator head


42


in substantial alignment with the central longitudinal axis of the reservoir


12


.




Referring now to

FIGS. 4A and 4B

in particular, the offset nature of the stem


48


facilitates insertion of the applicator


40


into the reservoir


12


while still permitting a close approach of the magnets


32


,


46


, limited only by the thickness of the reservoir sidewall


18


. The base


44


extends a first distance L, to one side of a longitudinal axis through the applicator, and the head


42


extends a second distance L


2


to an opposite side of that longitudinal axis. Preferably the combined first and second distances L


1


and L


2


are greater than the inner diameter of the reservoir open end


16


(or neck


19


). The offset nature of the stem allows the base


44


to snugly pass centrally through the reservoir open end


16


and neck


19


during the container assembly operation (see

FIG. 4A

) and then be relocated to situate the interior magnet


46


on or closely adjacent to the interior of sidewall


18


, opposite the exterior magnet


32


, while leaving the applicator head


42


lying substantially along the central longitudinal axis of the reservoir


12


(see FIG.


4


B).




In a preferred embodiment the container


10


additionally includes a stationary flow controller, generally designated


50


, extending through the neck


19


and reservoir open end


16


in fluidtight relationship therewith. As best seen in

FIG. 3

, the interior of the flow controller


50


defines a central flow channel


52


having a fluidtight sidewall. The flow controller


50


includes flow restricting means


54


to limit the flow of cosmetic from the reservoir interior into the central flow channel


52


and also acts as a wiper to remove excess cosmetic from the applicator head


42


as it is being moved outwardly (upwardly) from reservoir


12


. The flow controller


50


has an outwardly extending flange


56


adjacent the top thereof for supporting the flow controller


50


on the reservoir open end


16


. The opposite end of flow controller


50


includes resilient means


58


which can resiliently collapse towards one another to enable passage of the resilient means


58


through the open end


16


and neck


19


of the reservoir


12


during the container assembly operation and then expand outwardly to abut from below the shoulder


60


formed by the reservoir neck


19


. The flange


56


and resilient means


58


cooperate to prevent accidental dislodgement of the flow controller


50


from the reservoir


12


.




As illustrated in

FIG. 3

, the resilient means are four legs


58


, each adjacent pair of legs defining therebetween a channel


62


to restrict and limit the flow of cosmetic from the reservoir interior into the central flow channel


52


. Clearly a different number of legs


58


and channels


62


may be used. The number, length, width and configuration of the channels


62


as well as the viscosity of the cosmetic are significant factors in determining the quantity of cosmetic which can pass into the central flow channel


52


. Where the cosmetic includes a volatile constituent, the quantity of this constituent passing into the central flow channel


52


is less affected by the characteristics of the channels


62


. It will be appreciated that clearly other conventional means may be employed to stabilize the position of the flow controller


50


in the container


10


and to reduce the avenues for cosmetic flow into the central flow channel


52


.




The applicator


40


preferably has a ferrule


70


disposed on the stem


48


adjacent the head


42


thereof. The ferrule


70


is configured and dimensioned to fit snugly into the central flow channel


52


for reciprocating sliding movement relative thereto. The ferrule


70


, cooperatively with the central flow channel


52


, performs several significant functions.




Referring now to

FIGS. 2A through 2C

in particular, the arrowed lines indicate the cosmetic flowpath as affected by the ferrule


70


and central flow channe


152


.




First, when the ferrule


70


is substantially spaced below both the central flow channel


52


and the tops of the channels


62


, it permits cosmetic to flow freely (when inverted, under the influence of gravity) from the channels


62


into the central flow channel


52


forwardly of the ferrule


70


. Thus, as illustrated in

FIG. 2A

, when the applicator head


42


is totally within the central flow channel


52


, the ferrule


70


is positioned to permit free flow of cosmetic into the central flow channel


52


. Preferably the channels


62


defined by resilient legs


58


are of sufficient size to enable relatively free passage of cosmetic from the reservoir interior into the central flow channel


52


absent any blockage by the ferrule


70


. Accordingly, in the storage position (with cover


20


in place) the applicator head


42


is maintained saturated with the cosmetic within the reservoir interior when the container


10


is inverted or in gaseous communication with any volatile solvent in the cosmetic (whether the container


10


is inverted or not). Escape of the cosmetic or volatile solvent is precluded by the presence of the cover


20


closing the reservoir open end


16


.




Second, when the upper face of ferrule


70


is closely adjacent to the entrance of the central flow channel


52


(but still spaced therefrom) and not as high as the top of the channels


62


, it restricts and limits (but does not preclude) cosmetic flow from the reservoir


12


into the central flow channel


52


.




Third, as the ferrule


70


is driven upwardly into and through the central flow channel


52


, it pumps cosmetic from the reservoir interior (and channels


62


) into the central flow channel


52


. Thus, as illustrated in

FIG. 2B

, as the applicator head


42


is being extended outwardly (upwardly) from the central flow channel


52


(in response to manual upward movement of the exterior magnet


32


), the ferrule


70


acts as a piston and pumps cosmetic into and through the central flow channel


52


and from there onto the applicator head


42


. Accordingly, after the cover


20


is removed and as the applicator head


42


is being advanced to a use position, the ferrule


70


drives forwardly any of the cosmetic that was intermediate the forward face of the ferrule


70


and the rear of the central flow channel


52


, the cosmetic being forced either to return outwardly through the channels


62


(back into the reservoir


12


) or to pass forwardly through the central flow channel


52


for discharge from the container


10


.




Fourth, when the ferrule


70


is within the central flow channel


52


, it precludes cosmetic flow from the reservoir interior into and through the central flow channel


52


. Thus, as illustrated in

FIG. 2C

, when the applicator head


42


extends outwardly (forwardly) from the central flow channel


52


, the ferrule


70


is positioned to block passage of the cosmetic from the channels


62


into the central flow channel


52


. Accordingly, when the applicator head


42


is fully extended (i.e., above the reservoir open end


16


), the ferrule


70


blocks any further communication between the cosmetic within the reservoir interior and the environment (by blocking off the central flow channel


52


) so that the airtight integrity of the container


10


is resumed.




Accordingly, the combination of the ferrule


70


and the flow controller


50


provides for various functions as follows:




First, means for maintaining the applicator head


42


in fluid communication with the cosmetic via central flow channel


52


when the container


10


is stored in an inverted orientation. Where the cosmetic includes a volatile solvent, the maintaining means also maintains the applicator head


42


in gaseous communication with the volatile solvent more-or-less regardless of the container orientation. The ferrule


70


is outside of the central flow channel


52


when the cover


20


closes the reservoir open end


16


, and thus not interfere with fluid flow to the applicator head


42


.




Second, means for applying cosmetic to the applicator head


42


via central flow channel


52


as the ferrule


70


is moved upwardly into the central flow channel


52


and the applicator head


42


is correspondingly moved upwardly through the reservoir open end


16


.




Third, means for sealing the reservoir open end


16


(that is, the central flow channel


52


) about the applicator


40


while the applicator head


42


is outside of the reservoir


12


(above the open end


16


), thereby to preclude atmospheric exposure of the cosmetic within the reservoir


12


.




The flow controller


50


preferably extends centrally through the reservoir neck


19


and open end


16


so that it also acts as the means for maintaining the applicator head


42


in substantial alignment with the central longitudinal axis of the reservoir


12


.




In order to load the applicator head


42


with the cosmetic, the applicator


40


is withdrawn to the storage position and the cover


20


placed on the reservoir


12


, the container


10


is then briefly inverted (to allow the cosmetic or other flowable material to flow into and through the channel


62


and the central flow channel


52


onto the applicator head


42


), and finally the container is placed in a use orientation and the applicator


40


is extended into the use position. Depending upon the characteristics of the channels


62


and the cosmetic itself, it may be possible to perform the reloading procedure (including inversion of the container) without application of the cover


20


to the container to close the open end


16


thereof.




Referring now to

FIG. 5

in particular, therein illustrated is a brace of the containers


10


as previously described except that the reservoirs


12


are axially aligned so that the covers


20


are joined in head-to-head relationship in a common cover


20


′ for movement as a unit. This assembly facilitates the transport of two different cosmetics, whether it be cosmetics that are used jointly, for example, (a base lipstick and a lip gloss) or separately (two different shades of lipstick, one for the upper lip and one for the lower lip).




While the airtight magnetic applicator system of the present invention has been described and shown herein in the context of a cosmetic container, it will be appreciated that the principles of the present invention may find utility in a wide variety of non-cosmetic applications, particularly those where the contents is a flowable material (be it a powder, a liquid or a liquid having a volatile component therein) to be stored within the container and applied therefrom in such a manner as to minimize exposure of the contents to the environment (either to protect the environment from the contents or to protect the contents from the environment).




To summarize, the present invention provides a cosmetic container wherein the cosmetic within the container is not exposed to the environment outside the container even during application of the cosmetic, yet the applicator head is in fluid communication with the cosmetic when the cover is on the container. The applicator head may be used to apply the cosmetic to an intended wearer while other portions of the applicator preclude exposure of the cosmetic remaining within the container to the environment. The container is simple and inexpensive to produce, easy to use and maintain, and compact and attractive in configuration.




Now that the preferred embodiments of the present invention have been shown and described in detail, various modifications and improvements thereon will become readily apparent to those skilled in the art. Accordingly, the spirit and scope of the present invention is to be construed broadly and limited only by the appended claims, and not by the foregoing specification.
