Modern generation sealed compact case

Abstract

A cosmetic compact having a base, and a lid assembly having a window hingedly connected to the base. The lid assembly and window are movable between open and closed positions. A platform member carries the cosmetic product, and can move in the manner of a float between the base and lid assembly. A cam mechanism on the window in the form of depending lugs, cooperates with camming ramps on the platform member. Exteriorly accessible manually engageable grip members connected with the platform member, allow the latter to be rotated with the lid assembly closed. Such rotation effects a tightening of the seal between the window and the platform member, by virtue of the action of the window lugs on the platform member's camming ramps. Improved seal between the window and the platform member is accomplished by virtue of such tightening. In addition, the arrangement is such that the compact can be locked against inadvertent opening, simultaneously with the tightening and sealing action on the platform member.

Field of the Invention

This invention relates generally to cosmetic containers, and more particularly to containers of a type intended to provide an improved seal when the container is disposed in a closed position, as during storage, shipping or between uses.

BACKGROUND OF THE INVENTION

The following references are believed to relate to the technical field to which the present invention pertains:

U. S. Pat. Nos.: 1,672,417 1,818,409 2,054,004 2,182,040 5,186,318 5,884,636 5,909,738 7,464,820

Considering the patents chronologically, U.S. Pat. No. 1,672,417 discloses a compact having a closure hinged to a circular body, and wherein a locking member for the closure is movably mounted in an angular slot in the body outer wall. The locking member can latch onto a bead or rib formed on the underside of the closure, according to its angular disposition on the body. It is slidable within limits, to oppositely disposed angular positions corresponding to a locked condition of the closure, or an unlocked condition thereof, the latter case permitting the closure to swing open, for use.

U.S. Pat. No. 1,818,409 shows a structural arrangement somewhat similar to that of the previously noted patent. A locking member is slidable on the outer wall of a cosmetic compact body, and has an inwardly extending projection that can travel along an internal rib on the underside of the compact's hinged closure. The operation is the same as in the previous device, wherein opposite angular positions of the locking member on the body correspond to openable or locked conditions, respectively, of the closure.

U.S. Pat. No. 2,054,004 illustrates a vanity case having a cup-like body and a closure hinged thereto. Within the body is a product-carrying tray for cosmetic material. The tray is captive but movable in the body, being spring loaded by metal leaves, toward an upward position. A gasket on the rim of the tray is engaged by the underside of the closure, and the latter in turn presses down on the tray's rim to form a seal therewith.

U.S. Pat. No. 2,182,040 relates to a container with a twist-on closure. Internal cam lugs in the container are provided on a metal strip at the container opening, and corresponding exterior grooves in the closure fit the cam lugs, to enable screwing of the closure to a sealing position.

U.S. Pat. No. 5,186,318 describes several air-tight, hinged containers for cosmetic products. In each case, the seal between the container body and its closure is effected by means of a resilient gasket on the container lip. The gasket has a thin, peripheral compressible curl or set, which can be deformed by the closure when the latter presses on it.

U.S. Pat. No. 5,884,636 involves a cosmetic container having a body, a screw cap, and a hinged inner tray on the body. The latter includes a peripheral lip, which seals against a flat window portion of the screw cap. The seal is indicated by the numeral 38 in FIG. 2 of the patent.

U.S. Pat. No. 7,464,820 relates to a compact case having a body, a hinged closure, and an inner tray which forms a first compartment for cosmetic powder and a second compartment for a powder puff. The periphery of the body features an upwardly facing groove having liquid rubber introduced therein and allowed to cure in situ. Peripheral seals are formed for both compartments when the compact is closed.

U.S. Pat. No. 5,909,738 discloses a cosmetic case having a body, a hinged lid, and a floating product-carrying tray. Disposed between the tray and the side wall of the body is a turnable ring having an operating button which extends outwardly through a peripheral groove in the body. The tray and ring have cam components by which the tray can be manually shifted inside the body, and biased upwardly into firmer engagement with the lid underside. A keying lug on the bottom wall of the body fits into a cooperable vertical slot in the tray, to prevent rotation of the latter when the ring is turned by its button. An especially firm engagement between the tray and the lid is claimed to occur, along with an improved seal of the tray contents.

SUMMARY OF THE INVENTION

While the cited patents show both old and more recent cosmetic container proposals, it is believed that heretofore, no particular item stands out as having met with a large degree of success. This could perhaps be a result of unacceptable operation, promotional difficulties, financial considerations and the like. Accordingly it is considered that there still exists a need for a viable, reliable and workable sealed cosmetic compact in the field, especially considering the needs that some products demand, namely freedom from drying out due to long term exposure to the air, resulting from a poorly sealed container.

It is considered that the present invention fulfills at least some of the following objects:

To provide a novel and improved sealed cosmetic compact which is truly reliable in operation, as far as both short-term and long-term sealing characteristics are concerned.

To provide an improved cosmetic compact as above, which in operation, features a simple lever-type manual movement involving simultaneous closing and sealing functions.

To provide an improved cosmetic compact in accordance with the foregoing, which can be readily manufactured in plastic, using straightforward mold cavities.

To provide an improved cosmetic compact of the type noted, which features long life, and high resistance against breakage or other malfunction.

To provide an improved cosmetic compact as above characterized, which provides a clear, untinted and frost-free viewing window, to enable the exact color of the cosmetic substance contained in the compact to be quickly and easily determined by the user.

To provide an improved cosmetic compact in accordance with the above, wherein different prismatic lateral surface configurations can be incorporated in the compact exterior, to accommodate differing visual tastes and/or impressions as might be required, for different customers.

In a preferred embodiment, the invention provides a cosmetic compact, comprising in combination a base, a lid assembly and a hinge pivotally connecting it to said base, said lid assembly comprising a cover having an expansive central opening, said lid assembly further comprising a window fitted in said expansive central opening and sealingly engaged therewith, said window having a downwardly facing, circular sealing surface, and further having a plurality of depending radially inwardly facing latching lugs circumferentially spaced about the periphery of the window, a substantially cylindrical platform member disposed between said base and said lid assembly, said platform member being captive therein and further being movable within limits in both a vertical and a horizontal direction with respect to said base and lid assembly, and being turnable therein, said platform member further having an upwardly facing circular sealing surface adapted to seal against the sealing surface of the window, said base having an upwardly facing, semi-circular bearing surface against which said platform can rest or alternately be manually turned within limits, said base further having a pair of upwardly facing cut-outs in said bearing surface, said platform member having two oppositely disposed radially extending bridges, extending outward through said cut-outs in the base, respectively, a pair of manually-engageable substantially semi-circular actuator grip members on said bridges, respectively, and disposed at the exterior of said base so as to be accessible to the fingers of the user, and a series of circumferentially disposed cam ramps on the exterior of said platform member, said cam ramps having clearance spaces between them to receive the respective latching lugs of the window, whereby upon turning of the actuator grip members when the lid assembly is closed, the window latching lugs ride along the cam ramps to exert a force on the platform member in a direction tending to tighten engagement between said circular sealing surfaces on the window of the lid assembly and on the platform member, and thus reinforce a seal therebetween.

Other features and advantages will hereinafter appear.

DESCRIPTION OF THE PREFERRED EMBODIMENTS, AND BEST MODES KNOWN FOR CARRYING OUT THE INVENTION AS OF THE PRESENT FILING DATE

By way of introduction, the cosmetic compact to be described features a total of three basic operating conditions, namely an open position wherein the contents of the compact are made available to the user; a closed, unlocked position in which the compact is held solely by means of a latch; and a closed, locked and sealed position, which avoids inadvertent opening, and simultaneously effects an air-tight seal of the compact's contents. In the following description, the terms ‘closed and sealed’; and ‘closed and locked’ will be used interchangeably, and are intended to be equivalent terms throughout.

Considering FIGS. 1-5 and 10-13, there is illustrated a cosmetic compact generally designated by the numeral 10. It is seen that the compact exterior is substantially completely cylindrical. A lid assembly 12 to be described hereinbelow is pivotally connected to a base 14. A pair of actuator grip members 16, 16, is disposed midway between the base 14 and lid assembly 12, which operate to lock or unlock the lid assembly.

Considering the exploded views of the compact in FIGS. 6 and 7, the lid assembly 12 comprises a ring member 20 and a window 22. The window 22 is preferably constituted of clear or semi-transparent plastic, to permit the contents of the compact to be viewed. Returning again to the figures, the lid assembly's ring member 20 is pivotally connected to the base 14 by means of a hinge 26. In the illustrated example, an additional hinge 28 is provided, for another part of the compact involving a separate door at the underside of the base, and a mirror associated therewith, these second components not being further addressed in the present discussion.

In accordance with the invention there is provided a novel and improved mechanism for locking the compact in its locked, closed position, FIGS. 1, 10 and 12. Simultaneously with said locking, there occurs a minute but finite vertical movement of a platform member 30, FIGS. 3 and 7. The platform member 30 has a body 31, and the cosmetic substance of powder or other material is carried in a upwardly facing recess in the platform member body 31, for access by the user in the usual manner when the compact is disposed in its open position, FIG. 3.

Referring to FIG. 3, and FIGS. 8a-8f, in accomplishing the seal of the platform member contents, the window 22 is provided with a circular rim 32 on its underside, having a sharp circular edge indicated 23. The window 22 is rigidly affixed in the ring member 20 to the end that both move together as a unit. Disposed on the underside of the window 22 are six circumferentially spaced depending lugs 36, FIGS. 8b-8f. The lugs are molded integrally with the remainder of the window.

Considering now the base 14, as noted above, it is cylindrical in shape, and in addition to the hinge 26 and latch 38, the interior of the base 14 is provided with opposed semi-circular, upwardly facing bearing surfaces 42, FIG. 6, which support a cooperable lower circular slide bearing surface 44, FIGS. 6 and 7, on the platform member 30. In operation, the platform member 30 can be slidably turned on the base bearing surfaces 42 during the locking and sealing phases of the compact.

Referring again to the base 14 in FIGS. 6 and 7, it will be seen that interposed between the bearing surfaces are two recesses or cutouts 46, which provide clearance for components to be described. Also, adjacent to the cutouts 46 are elongate, angular recesses 47, which provide clearance to receive two bridges 48, 50 respectively, on two actuator grip members 16, 16. See FIGS. 6 and 7. The bridges 48, 50 connect the platform member body 31 to the two actuator grip members 16, 16, respectively. The platform member 30, bridges 48, 50, and grip members 16, 16 are all molded integrally with one another, and thus remain rigidly fixed together. Furthermore, it can be seen that the bridges 48, 50 can be slid between two pairs of stop surfaces on the base 14, one pair being numbered 52 and 54 in the figures.

Further by the invention, the integrally molded lugs 36 of the window 22, are receivable during closing of the compact, through six corresponding recesses that are disposed between six individual camming ramps 60 on the exterior of the platform member 30. Several of these lugs 36 can be seen in FIGS. 3 and 8. The platform member 30 is thus turnable on the base 14 and with the compact closed, between opposite positions, shown in FIGS. 1 and 2, respectively. The surfaces 52, 54 and 56, 58 limit the movement to a fraction of a turn. With the lid assembly closed, the six window lugs 36 can be brought into engagement with the six camming ramps 60 respectively, on the platform member 30. Thereafter, when the grip members 16, 16 are manually turned, the window lugs 36 ride along the ramps 60 to thereby pull up a platform member gasket 62 against the circular window rim 32.

The details of the seal can be seen in FIGS. 15-20. FIG. 15 is a front elevation of the compact 10, shown in a closed and sealed position and illustrating the base 14, the lid assembly's ring member 20, and two actuator grip members 16, 16, positioned in the closed and sealed position as indicated by the marker arrow 64, FIG. 15. FIG. 16 is a vertical section taken on the line 16-16 of FIG. 15, again illustrating the base and lid assembly of FIG. 15. FIG. 17 shows an enlarged detail of particulars of the seal between the window 22 and the gasket 62 of the platform member 30.

Upon shifting of the grip members 16, 16 to a position opposite to that of FIGS. 15-17, movement of the platform member 30 occurs. In FIGS. 18-20, the platform member 30 has dropped, by gravity, as occurs when the window lugs 36 have released it by virtue of their having been moved out of engagement with the respective camming ramps 60. In FIGS. 19 and 20, a small space is seen to exist between the edge 23 of the depending skirt of the window 22 and the platform member gasket 62. From this position the compact can be opened as in FIG. 3, to reveal the cosmetic material contained therein.

With the arrangements shown in FIGS. 15-20, the net effect is to render the seal between the platform member gasket 62 and the window 22 virtually completely air-tight, and to thus isolate the cosmetic material from the outside air. The platform member gasket 62 is preferably deposited onto the platform member 30 at the time the latter is molded.

In summary, then, the compact can be stored in the closed, locked position of FIG. 10. The grip members 16, 16 each conceal their respective underlying marks or marker arrows 64 that appear as in FIGS. 10 and 12. When uncovered by actuation of the grip members 16, 16, the marker arrows indicate to the user the direction in which one can shift the grip members 16, 16 in order to reestablish the locking position of the compact. It will be understood that when the grip members 16, 16 are manually shifted by the user, the entire platform member 30 is rotated inside the closed compact, to effect the sliding up of the six window lugs 36 on their respective the camming ramps 60 on the platform member 30.

Finally, in order to avoid interference between the camming ramps 60 and the window lugs 36, the base and at least one of the grip members 16 have cooperable detent ribs 66 and 68, respectively, FIGS. 7 and 14, which resist inadvertent movement of the platform member out of an intermediary position wherein the spaces between the camming ramps 60 might not align with the window lugs 36. Under such an undesirable condition, the window assembly could jam against the platform member, and render the compact incapable of fully closing. The provision of the detent ribs 66, 68 prevents such interference, by retaining the platform member and grip members in a position essentially the same as that occupied during unlocking and unsealing of the platform member. Preferably both of the grip members 16, 16 are provided with a detent rib such as 68, and both outer surface locations of the base provided with detent ribs 66.

Additional features of the disclosed construction include the provision of the grip members 16 having an elongate and arcuately curved shape, to conform to the contour of the recesses 47. With such an arrangement, the grip members' exterior surfaces constitute continuations of the cylindrical surface of the base exterior, thereby eliminating unsightly protruding lugs or catches of any kind. The locations of the grip members on the compact are such that they are opposite one another, and can be considered to span both the hinge and the latch of the compact, circumferentially. The exterior surfaces of the grip members are ribbed, as shown, but other forms of non-smooth surface irregularity could be substituted, the important consideration being that their engagement by the fingers of the user be facilitated, as during opening or closing of the compact.

Another embodiment of the invention is illustrated in FIGS. 21-24. Reference numerals with the suffix “a” have been added to those parts which correspond to the similarly labelled components of the first embodiment. Unlike the first arrangements of the compact, the present version has incorporated square components for the base and lid assemblies, but with most of the internal parts remaining circular or cylindrical, in both structure and function.

In this second embodiment, FIG. 21 illustrates the appearance of the compact when the latter is in either a closed and unsealed position or a closed and sealed position. FIG. 22 shows the compact fully open, with access to the contents of the compact contained in the body 31a.

Both FIG. 23 and FIG. 24 are exploded perspective views of the internal structures of the rectangular compact. Specifically, the compact includes a lid assembly 12a, compact base 14a window 22a and window frame member. Hinge parts 26a pivotally connect the window frame member to the base 14a. The cosmetic material to be stored is carried in a platform member 30a. The base is formed as four box-like corners. Two of the four corners contain annular slots labelled 70 and 72 respectively, FIG. 22. These slots have a curvature which matches the curvature of the grip members 16a, 16a, and the latter thus slide angularly in the respective slots, to provide a neat and finished appearance, and to conceal all surfaces of the grip members 16a, 16a, except the exterior surfaces thereof, which are textured to facilitate their engagement by the finger and thumb of the user.

Attached integrally to the window 22a is a plurality of depending lugs 36a which lie radially outside a circular window rim. Actuator grip members 16a, 16a are integrally formed with the platform member and joined thereto by means of bridges 48a, 50a, respectively. Stop surfaces 52a, 54a, 56a, and 58a function to limit the travel of the grip members 16a, 16, respectively, as in the first embodiment.

The platform member sealing gasket 62a is shown in FIG. 22. However, marker arrows similar to those indicated 46 in the previous embodiment, are not shown in the disclosed arrangement. Nor have the parts corresponding to reference numerals 66 and 68 of the first embodiment been included in this construction.

Still another embodiment of the invention is illustrated in FIGS. 25-28, showing a compact having a distinctive oval outer surface configuration. Reference numerals with the suffix “a” have been added to those parts which correspond to the similarly labelled components of the first embodiment. It is to be noted that most of the internal parts of this oval compact are circular or cylindrical, in both structure and function.

In this embodiment, FIG. 25 illustrates the appearance of the compact when the latter is in an unsealed condition. The base is labelled with the reference numeral 14b, and the lid assembly is designated 12b. The latch 38a is of similar configuration to that of the previous constructions.

Returning to the figures, the base is seen to have the outer surface configuration of an oval geometric shape, that is, the geometric configuration of the lateral or side surfaces of an oval prism. In this connection, the lid assembly is seen to overlie the base so as to meet it along the full circumference, that is, the lid assembly is substantially congruent with the base. Finger-engageable bridges 16b are also provided, as in the first embodiment. The bridges 16b are opposite one another, as seen in FIG. 27, and a marker 64b is provided on a recess which accommodates the bridges. Only one marker is shown in the figures, the other being on the reverse side to that illustrated in FIG. 28.

In general, the inner structural details of the embodiment of FIGS. 25-28 are substantially the same as those of the first embodiment, as regards the platform member and the lid assembly which carries the window.

Yet another embodiment of the invention is shown in FIGS. 29-32, wherein the compact base and lid assembly overlie one another as previously, and where the base and lid assembly have the configuration of a modified rectangular configuration with two opposed lateral surfaces bulging outwardly with respect to one another. This feature is best displayed in FIG. 30. The remaining two opposite sides of the base and lid assembly are substantially parallel, again as seen in FIG. 30.

Reference numeral 38b is provided on the latch, whereas the finger engageable bridges are assigned 16c. Marks 64c in the path of the bridges indicate to the user, the direction in which to slide the bridges, in order to unlock the compact.

The illustration of alternate lateral surface configurations is given in a general sense, and not to be construed as limiting. As can be readily understood, further modifications to the general overall external appearance can be envisioned, with the essential quality of providing a substantially completely air-tight connection between the platform member and the window of the lid assembly. For example, the lateral external sides of the compacts can comprise geometric prism configurations of triangular, pentagonal, or hexagonal character, and also slight modifications of the precise shape is hereby proposed, within the scope of the present disclosure.

An additional feature of the present invention is the provision of a window of exceptional clarity. Many prior airtight compacts currently utilize PP, which tends to be cloudy and not crystal clear, or alternately may contain coloring which conceals the true hue of the cosmetic material being dispensed. Colored, stick-on labels are often used with such compacts, to indicate the nature of the shade of the material being dispensed.

By the present invention, the windows are constituted of hard, clear crystalline material, having excellent clarity, to facilitate viewing of the exact hue of the cosmetic material contained in the compact. At the same time, such a window can also provide chemical resistance from volatile gases often contained in cosmetic substances. Use of PCTA (co-polyester), PET (polyester) and/or CN (cellulose nitrate) are examples of plastics which can be used with the invention.

From the above it can be seen that I have provided novel and improved cosmetic compacts which are straightforward in their construction, and which provide a most effective seal of cosmetic material which is placed and stored therein, especially over a lengthy period of time.

Significantly reduced possibility of evaporation of volatile contents in the stored matter is realized. Yet ease of use is retained through the provision of readily accessible, exterior finger grip members on the compacts' exterior surfaces.

The compacts are thus seen to represent a distinct advance and improvement in the cosmetic field.

Each and every one of the appended claims represents an aspect of the invention which is separate and distinct from all others, and accordingly it is intended that each claim be treated as such when examined in the light of the prior art devices in any determination of novelty or validity.

Variations and modifications are possible without departing from the spirit of the invention.
