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.
