Description




CROSS-REFERENCE TO RELATED APPLICATION




This application claims priority of Taiwan Patent Application No. 090202229, filed on Feb. 14, 2001.




BACKGROUND OF THE INVENTION




1. Field of the Invention




The invention relates to a cosmetic case, more particularly to a multi-layered cosmetic case.




2. Description of the Related Art




Referring to

FIGS. 1 and 2

, a conventional multi-layered cosmetic case is shown to comprise a horizontal base


91


, a hollow pivot


92


disposed vertically on the base


91


proximate to an edge of the base


91


, a stack of trays


93


pivotally connected to the pivot


92


, and a top cover


94


. The trays


93


are used for storing cosmetic items. The top cover


94


is disposed to cover the trays


93


when the latter are stacked in alignment.




Since the trays


93


are not interconnected to each other by engaging members, the trays


93


move independently so that only one tray


93


can be moved and opened at a time, as best illustrated in FIG.


2


. Thus, the conventional multi-layered cosmetic case is inconvenient to use. Furthermore, the top cover


94


is easily misplaced.




SUMMARY OF THE INVENTION




Therefore, the main object of the present invention is to provide a multi-layered cosmetic case with a stack of trays that can be opened and closed simultaneously.




Accordingly, a multi-layered cosmetic case of the present invention comprises a frame unit and a stack of trays. The trays are mounted pivotally on the frame unit, and are turnable about a single axis to move between a closed position in which the trays are aligned with each other, and an open position in which the trays are out of alignment from each other. Each of the trays lags behind an adjacent one of the trays during turning movement of the trays, and has an open top with a top edge, a closed bottom, a first engaging member disposed at one of the top edge and the closed bottom, a slide rail disposed in the other one of the top edge and the closed bottom, and a second engaging member disposed adjacent to the slide rail. The first engaging member of each of the trays is slidable along the slide rail of the adjacent one of the trays for relative movement therebetween and subsequently engageable with the second engaging member of the adjacent one of the trays for subsequent simultaneous movement therebetween.

to cause subsequent simultaneous movement of the adjacent first trays


3


.




The frame unit


1


includes a top wall


11


extending above the first trays


3


, a bottom wall


12


extending below the first trays


3


, and a side wall


14


interconnecting the top and bottom walls


11


,


12


and extending adjacent to one of the first lateral sides


34


. The top wall


11


has a slot


113


which is similar in configuration to the slot


32


in each of the first trays


3


and which has two opposite engaging ends


114


,


115


.




The first trays


3


include an uppermost tray


38


disposed adjacent to the top wall


11


and connected pivotally to the top wall


11


via a pivot


111


and the pivot hole

in the lowermost tray


39


of the first trays


3


. The second tray


4


includes a second pivot end


42


substantially aligned with the first pivot ends


35


, and two opposite second lateral sides


47


which substantially extend along the first lateral sides


34


but longer than the latter. The second tray


4


further has a cover wall


45


, a distal end


49


(shown in FIG.


5


), an extension region


43


(shown in FIG.


5


), a tray recess


48


, and a receptacle


46


. The cover wall


45


extends at one of the second lateral sides


47


opposite to the side wall


14


of the frame unit

, and projects upwardly to cover the first trays


3


. The distal end


49


is opposite to the second pivot end


42


. The extension region


43


is adjacent to the distal end


49


. The tray recess


48


is in alignment with the first trays


3


. The receptacle


46


is disposed in the extension region


43


, and extends toward the top wall


11


. The receptacle


46


is used for storing a cosmetic brush


50


.




The first and second trays


3


,


4


are interconnected via the pivot pin


5


which passes through the pivot holes


30


in the first trays and the pivot hole


40


in the second tray


4


. The first and second trays


3


,


4


are then mounted pivotally on the frame unit


1


by engaging the pivot hole


30


in the uppermost tray


38


with the pivot


111


of the top wall


11


and by engaging the pivot hole


40


in the second tray


4


with the pivot


121


of the bottom wall


12


. The first and second trays


3


,


4


and the top and bottom walls


11


,


12


are now aligned and in a closed state.




The outer profiles of the top and bottom walls


11


,


12


are substantially similar to that of the second tray


4


. The top and bottom walls


11


,


12


have the aligned pivots


111


,


121


in the pivot ends


119


,


129


, and extension regions


118


,


128


distal to the pivot ends


119


,


129


. The top wall


11


is further formed with a through hole


117


in the extension region


118


that is registered with the extension region


43


in the second tray


4


.




The second tray


4


and the frame unit


1


are further provided with releasable interlocking elements such as a bottom tab


44


, a locking groove


122


, a side tab


451


, and a locking notch


141


. The bottom tab


44


projects downwardly from the cover wall


45


, and engages releasably the locking groove


122


. The side tab


451


projects sidewise, and engages releasably the locking notch


141


. As such, the first and second trays


3


,


4


can be retained in the closed state on the frame unit


1


.




In use, the bottom tab


44


of the second tray


4


or the side tab


451


of the cover wall


45


can be moved away from the locking groove


122


in the bottom wall


12


or the locking notch


141


in the side wall


14


with the use of a finger. At this time, the protrusion


41


of the second tray


4


moves from one end


321


to the other end


322


of the slot


32


in the lowermost tray


39


. The lowermost tray


39


then moves after the second tray


4


has been turned by an angular distance. Similarly, the protrusion


31


of the lowermost tray


39


moves from one end


321


to the other end


322


of the slot


32


in the adjacent one of the first trays


3


. The same movement occurs successively in the other first trays


3


, such that each of the first trays


3


lags behind the adjacent one of the first trays


3


during turning movement of the trays


3


,


4


about the pivot pin


5


, as best illustrated in

FIGS. 5 and 6

. Finally, the protrusion


31


of the uppermost tray


38


abuts against one end


115


of the slot


113


in the top wall


11


, and is retained thereat. The first and second trays


3


,


4


are now opened, and are moved out of alignment from each other and from the frame unit


1


(see FIG.


5


).




When the protrusion


41


of the second tray


4


is moved in a reverse direction, that is, from the end


322


to the other end


321


of the slot


32


in the lowermost tray


39


of the first trays


3


, the protrusion


3


l of the lowermost tray


39


also moves from the end


322


to the other end


321


of the slot


32


in the adjacent one of the first trays


3


. The other first trays


3


follow the same movement successively, as best illustrated in

FIG. 7

, until the protrusion


31


of the uppermost tray


38


of the first trays


3


abuts against the other end


114


of the slot


113


in the top wall


11


. The first and second trays


3


,


4


are now in a closed state, and are not only aligned with each other, but are also aligned with the top and bottom walls


11


,


12


of the frame unit


1


.




Therefore, the multi-layered cosmetic case of the present invention is easy to use because the trays


3


,


4


can be opened and closed simultaneously.




While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
