Abstract:
A cosmetic container with spring-biased mirror is provided. The cosmetic container has a lower compartment containing a mirror frame and mirror concealed within. The mirror frame is held in place against the force of the spring by a first flexible hinge which abuts a sidewall of the lower compartment. When the user desires to access the mirror, they press downwards upon a second flexible hinge in the tray of the container which holds the cosmetic. The flexible hinge in the tray is in relationship with the flexible hinge in the mirror frame. Thus, a downwards force applied to the flexible hinge in the tray transmits the downward force to the flexible hinge in the mirror frame. This force disengages the flexible hinge in the mirror frame from the sidewall of the lower compartment, thus permitting the spring to urge the mirror frame and mirror from their concealed position to their exposed position where the mirror is available for use.

Description:
BACKGROUND OF THE INVENTION  
         [0001]    The present invention relates generally to a compact case for cosmetics. More particularly, the invention relates to a compact case having a spring-biased mirror within its base, the mirror in its closed position being concealed within the base and out of communication with the cosmetic powder held within the receptacles of a tray overlaying the base. In operation, the user opens the lid of the compact overlaying the tray and depresses a flexible hinge within the tray whereupon the mirror is projected by a spring to an exposed position outside of the base of the compact where it is readily available for access by the user.  
           [0002]    Cosmetic holding cases or compacts with manually slidable or movable mirrors are known in the art. U.S. Pat. No. 2,205,974 to Kramer discloses a cosmetic holding device wherein the mirror is contained within the case and is slidable out of the interior of the case from its normally concealed position to a position where it can be observed by the user by grasping the edges thereof. After use, the mirror can be retracted to its normal concealed position by applying pressure thereto with the fingers. U.S. Pat. No. 2,582,593 to Kramer discloses an improved compact featuring the utilization of a slidably guided mirror adapted to be manually withdrawn from the closing cover of the compact. U.S. Pat. No. 5,398,706 to Epstein also discloses a compact case, here incorporating a pull out tray in the bottom compartment thereof for holding cosmetic components including a mirror.  
           [0003]    A lady&#39;s compact case incorporating a spring-loaded mirror therein is disclosed by U.S. Pat. No. 2,783,764 to Loy. This reference is to a compact having a normally concealed mirror which may be moved from its concealed position to an exposed position by a spring when a user moves a locking member attached to the mirror from its offset position in a locking slot disposed within the bottom of the case. The return of the mirror from its exposed position to its concealed position is effected by pushing the locking member backwards against the force exerted by the spring until the locking member has attained a position adjacent the locking slot whereby sidewards pushing of the locking member into the locking slot by the user effects the retention of the mirror in its locked position. One drawback of this invention is that the closing operation is clumsy and requires manual dexterity of the fingers which many older users of the compact may lack. Additionally, the appearance of a slot in and across almost the entirety of the width of the back of the case, with the locking member protruding there though, is unsightly and presents a means by which dirt or grit may enter the bottom of the compact and impair the operation of the slidable mirror. This slot also allows for snagging of the locking member on other articles within a purse or pocket thus increasing the likelihood of an accidental opening of the mirror.  
           [0004]    U.S. Pat. No. 2,771,083 to Darvie also presents a retractable mirror device, here associated with the use of a lipstick holder. In this device, the partial retraction or complete removal of a lipstick holder from a container associated with and in communication with the mirror via a latch, releases the spring-biased mirror for movement into its visible position. This invention, however, also presents several disadvantages. For example, in this device the mirror is only held in its closed position when the lipstick holder is disposed within its container. Thus, the user is unable to return the mirror to its closed position if the user desires to continue to use the lipstick holder by itself. Additionally, the mirror is always automatically released to its exposed position upon the removal or partial removal of the lipstick holder from its container. Thus, the user cannot use the lipstick alone without the mirror being projected out, even if the mirror is not desired to be used.  
         BRIEF SUMMARY OF THE INVENTION  
         [0005]    The present invention is a compact case for cosmetics having a spring-biased mirror within its base. In its closed position the mirror is concealed within the base of the compact and is out of communication with the cosmetic powder contents of the compact which are held within the receptacles of a tray overlaying the base. When the user desires access to the mirror, the user opens the lid of the compact and depresses a button in the form of a flexible hinge within the tray whereupon the mirror is projected outside of the compact by a spring for ready access by the user.  
           [0006]    It is an object of the present invention to overcome the problems of the prior art by providing a compact case with a spring-biased mirror which provides a simple means for securing the mirror in its closed, concealed position.  
           [0007]    It is a further object of the present invention to eliminate the projection of any securing means outside of the cosmetic case to reduce the likelihood of the mirror being accidentally released to its exposed position.  
           [0008]    It is yet another object of the present invention to eliminate any large openings within the cosmetic case when the mirror is in its closed, concealed position which might serve as a conduit for the entry of dirt into the spring mechanism.  
           [0009]    It is still yet a further object of the present invention to provide a cosmetic case with a spring-biased mirror wherein the user can access the cosmetic without triggering the mirror to move into its exposed position.  
           [0010]    These and other objects of the invention are met by the invention disclosed herein. The cosmetic case comprises a generally square-shaped base fabricated preferably of plastic having an upper compartment or tray containing one or more receptacles for the storage of cosmetics, such as blush, and an applicator brush. Directly beneath the tray is disposed a lower compartment within the base wherein resides a mirror supported within a mirror frame. The mirror frame is attached at one of its ends to one or more compression springs which are attached to a side wall of the lower compartment. The mirror frame rests between a substantially parallel pair of guide tracks protruding from the bottom wall of the lower compartment. Integrally molded on opposed sides of the mirror frame are a pair of stop tabs. These stop tabs serve to prevent the mirror frame from being completely ejected outside of the lower compartment by the action of the spring.  
           [0011]    The mirror frame is retained in its concealed position within the lower compartment against the biasing force of the compressed spring by means of a flexible hinge disposed in the mirror frame. In this concealed position, the leading edge of the flexible hinge in the mirror frame abuts against a sidewall of the lower compartment, thus holding the frame in place. To permit the spring to slidably move the mirror frame and mirror laterally from its concealed position to its exposed position outside of the base, a second flexible hinge disposed in the tray directly above and either in close proximity or direct communication with the flexible hinge in the mirror frame when the mirror frame is in its concealed position, is pressed downward by the user toward the mirror frame. In this manner the flexible hinge of the tray depresses the flexible hinge within the mirror frame such that the leading edge of the flexible hinge in the mirror frame is forced out of communication with the sidewall of the lower compartment. With resistance to lateral movement of the mirror frame thus removed, the compressed spring(s) uncoils and urges the mirror frame and its associated mirror along the guide tracks until the stop tabs on opposed sides of the mirror frame come into contact with a sidewall of the lower compartment. This contact stops the lateral movement of the mirror frame but not until the mirror is in its exposed position.  
           [0012]    Hingedly attached to the base is a cover, preferably of transparent plastic, which in its closed position fits over the base and protects the cosmetics contained within the receptacles of the tray from exposure to dirt, dust and precipitation and, in its open position, provides ready access to the cosmetics by the user.  
           [0013]    In normal operation the cosmetic container is transported in a purse, pocket or other carrying means with the cover in its closed position and the mirror in its retracted, concealed position inside of the lower compartment. When access to the cosmetic and/or the mirror is desired, the hinged cover is moved to its open position. If the user desires access to the mirror to aid in application of the cosmetic to the face, the flexible hinge disposed in the tray is depressed. This downward movement of the flexible hinge in the tray creates an associated downward movement of the underlying flexible hinge disposed within the mirror frame thus removing the leading edge of the flexible hinge in the mirror frame from its engagement with a sidewall of the lower compartment. The spring thus urges the mirror frame and mirror into its exposed position outside of the case.  
           [0014]    After the application of the cosmetic to the face is complete, the cover is typically moved to its closed position and the mirror frame returned to its concealed position within the lower compartment upon the application of a slight lateral force to the frame by the fingers in a direction opposed to the force of the spring so as to again compress the spring. As the frame is slid by this force so that it is returned to the lower compartment, the flexible hinge of the mirror frame again engages the sidewall of the lower compartment thereby retaining the mirror frame in its concealed position against the force of the compressed spring until its next use.  
           [0015]    In accordance with the foregoing objects, a compact case for cosmetics having a spring-biased mirror within its base is disclosed which overcomes the problems associated with the prior art.  
           [0016]    The novel aspects of the invention are set forth with particularity in the appended claims. The invention itself, together with further objects, features, aspects and advantages will be readily apparent to those skilled in the art and a better understanding of the present invention may be had by reference to the following detailed description taken in connection with the following drawings.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0027]    Referring now to the drawings there is shown in FIGS. 1, 2 and  3  a cosmetic container with spring-biased mirror. The cosmetic container  10  includes a preferably generally square-shaped base  12  having a front wall  13 , two sidewalls  14   a,    14   b,  a rear wall  15  and a bottom wall  16 . Overlaying base  12  is a tray  18  having one or more receptacles  20   a,    20   b  disposed therein for the storage of cosmetics and an applicator brush. The bottom wall  16  is in contact with and connected to front wall  13 , each of the sidewalls  14 , and the rear wall  15 . The front, rear and side walls are also in contact with and connected to the tray  18  to form a lower compartment  22  within base  12 . A generally square-shaped lid  24  is hingedly attached to the rear wall  15 . The lid  24  and the front wall  13  are provided with mating locking elements  26  of conventional design for effectuating the closure of the lid  24  of the compact  10 . It will be understood by those of ordinary skill in the art that the shape of the base  12  and lid  24  need not be generally square but may, alternatively, be generally rectangular, circular or of other geometric shape.  
         [0028]    The cosmetic container  10  is preferably formed from moldable plastic, such as acrylonitrile butadiene styrene (“ABS”) or the like, which makes the cosmetic container easy to manufacture using standard injection molding techniques. Lid  24  is preferably constructed of clear or transparent plastic such as styrene acrylonitrile (“SAN”) or the like.  
         [0029]    Front wall  13 , sidewalls  14   a,    14   b,  rear wall  15  and bottom wall  16  are preferably molded together to form a one piece base  12 . Lid  24  is separately molded and is attached to rear wall  15  by one or more hinges  32 . One of the sidewalls  14   a  contains an elongated rectangular-shaped opening  28  formed therein. Protruding from the bottom wall  16  into the lower compartment  22  formed by the front wall  13 , sidewalls  14   a,    14   b,  rear wall  15 , bottom wall  16  and tray  18  are a pair of guide tracks  30   a,    30   b  (see FIG. 8) oriented substantially parallel to each other and substantially perpendicular to opening  28  in sidewall  14   a.  On the sidewall  14   b  which is opposed to the sidewall  14   a  having the opening  28  disposed therein are formed one or more pins  34  (see FIG. 7) or other attaching means for purposes as will be further described.  
         [0030]    Referring to FIG. 8, disposed within the lower compartment  22  between the pair of guide tracks  30  is a mirror frame  36 . The mirror frame is formed of plastic, preferably ABS, with a recessed portion  38  (see FIG. 10) therein defined by flanges  39   a,b,c,d  for retaining and supporting a mirror  40  within the mirror frame  36 . Transverse play or chatter of the mirror frame  36  is precluded by the guide tracks  30  since both of the latter closely although movably confine the mirror frame  36 . Displacement of the mirror frame  36  widthwise of the lower compartment  22  is also prevented by the side edges  29  (see FIG. 2) of the elongated opening  28  which closely straddle the sides of the mirror frame  36  although permitting the latter to be displaced in and out of the lower compartment  22  through opening  28 .  
         [0031]    Integrally molded on opposed sides of the mirror frame are stop tabs  42 . (see FIGS. 3 and 7). Also integrally molded in the flange of the mirror frame farthest from opening  28  is pin  44  (see FIG. 8) or other attaching means for purposes as will be further described. Molded within the flange  39   a  of mirror frame  36  which is oriented closest to opening  28  is a first flexible hinge  48 . This flexible hinge  48  is formed in the flange  39   a  by removing a portion of plastic in the flange to create a hinge of any form or shape which remains secured to the flange but which by virtue of the removal of the surrounding plastic material can also be depressed or flexed by downward force applied by a user. When the downward force is lessened or removed, the flexible hinge  48  rebounds and returns to its original position relative to flange  39   a.  This cycle can be repeated numerous times without failure of the hinge.  
         [0032]    Also disposed within the lower compartment  22  are one or more compression springs  46 . Referring to FIGS. 7 and 8, the distal end of spring  46  is secured to a pin  34  of sidewall  14   b  and the opposed proximate end of each spring  46  is secured to a pin  44  of mirror frame  36 . It is to be understood that the number of compression springs, the geometry of the compression springs and the materials of construction of the compression springs employed are not to be construed as a limitation of the invention. While one compression spring is preferred and illustrated in the figures, two springs or more than two springs could just as easily be used and still be within the spirit and scope the invention.  
         [0033]    Overlaying the lower compartment  22  is tray  18 . Formed within the upper side  17  of tray  18  are one or more receptacles  20   a,    20   b  for the storage of cosmetics and an applicator brush. Also formed within tray  18  is a second flexible hinge  50  (see FIG. 3). In the position where the mirror frame  36  is in its concealed, retracted position, the second flexible hinge  50  overlays and is either close to or in contact with the first flexible hinge  48  formed within flange  39   a  of mirror frame  36 . The second flexible hinge  50  is formed in the same manner as the first flexible hinge  48 . When downward force is applied to the second flexible hinge  50  it deflects or flexes downward from the horizontal. When the downward force is lessened or removed, the second flexible hinge  50  rebounds and returns to its original position. This cycle can be repeated numerous times without failure of the hinge to rebound. P The operation of the cosmetic container  10  is hereafter described. While being transported by a user, the lid  24  is closed and secured to front wall  13  by locking elements  26 . The mirror frame  36  and mirror  40  are in their normally concealed position within the interior of the lower compartment  22 , positioned between the pair of guide tracks  30  protruding from the bottom wall  16 . The spring  46  is compressed between the mirror frame  36  and a sidewall  14   b  of the base  12 . The spring  46  and the mirror frame  36  are held in position against the force of the compressed spring  46  by the juxtaposition of the leading edge  52  of the first flexible hinge  48 , located in a flange  39   a  of the mirror frame  26 , against the inner surface  54  of the sidewall  14   a  having an opening  28  formed therein. (See FIGS. 5 and 9).  
         [0034]    When the user desires access to the cosmetic, they release the locking elements  26  and open the lid  24 . Should the user also desire to use the mirror  40  to aid in the application of the cosmetic to the face, the user depresses the second flexible hinge  50  located in the tray  18  by the application of a slight downward force in the direction of the bottom wall  16 . (See FIGS. 6 and 10). By this motion, leg  56  of the second flexible hinge bears downward upon the first flexible hinge  48  located in the mirror frame  36  with sufficient force to move and disengage the leading edge  52  of the first flexible hinge  48  out of its abutting communication with the inner surface  54  of sidewall  14   a.  Referring to FIG. 8, with resistance to lateral movement of the mirror frame  36  thus removed, the compression spring  46  uncoils and urges the mirror frame  36  carrying the mirror  40  laterally between the pair of guide tracks  30  and expels the mirror frame  36  out of opening  28  in the lower compartment  22  in the direction of arrow  58  until the stop tabs  42  strike the inner surface  54  of sidewall  14   a  (see FIG. 3), thus limiting the expulsion of the mirror frame  36  and retaining a portion of the mirror frame  36  within the lower compartment  22 . In this manner the mirror  40  is slidably moved from its concealed position into its exposed position and the mirror frame  36  is prevented from being ejected entirely from the lower compartment  22 .  
         [0035]    Once the user stops depressing the second flexible hinge  50  in tray  18 , the flexible hinge  50  rebounds and returns to its original position before downward pressure was applied. Similarly, once the leading edge  52  of the first flexible hinge  48  in the mirror frame  36  passes through opening  28 , it rebounds and returns to its original position.  
         [0036]    When the user has completed their use of the mirror  40 , the mirror frame  36  may conveniently be retracted to its normal concealed position within the lower compartment  22  by the application of slight lateral pressure against the frame by the user&#39;s fingers. The mirror frame  36  is thus moved laterally backwards in the direction of arrow  60  (FIG. 8) through the opening  28  in sidewall  14   a  against the force of the compression spring  46  until the leading edge  52  of the first flexible hinge  48  in the mirror frame  36  is again juxtaposed against the inner surface  54  of sidewall  14   a  and the leg  56  of the second flexible hinge  50  in the tray  18  is in contact with the first flexible hinge  48 . The user may close the lid  24  so that it mates with locking elements  26  either before or after the mirror frame  36  is returned to its concealed position.  
         [0037]    In this manner a cosmetic container with spring-biased mirror is provided which readily avoids the problems and shortcomings associated with the prior art. The present invention provides a simple means for securing the mirror frame  36  and mirror  40  in a closed, concealed position. The present invention eliminates the projection of any securing means outside of the cosmetic container  10 , thus reducing the likelihood of the mirror frame  36  and mirror  40  being accidentally released to the exposed position. There are no large openings in the cosmetic container  10  when the mirror frame is in its closed, concealed position which might serve as a conduit for the entry of dirt into the lower compartment  22  where it can interfere with the operation of the compression spring  46 . Finally, the user of the cosmetic container  10  can access the cosmetic without triggering the mirror  40  to move into its exposed position.  
         [0038]    The preferred embodiment has been illustrated and described. Further modifications and improvements may be made thereto as may occur to those skilled in the art and all such changes as fall within the true spirit and scope of this invention are to be included within the scope of the claims to follow.
