a first embodiment of the present invention is shown in fig1 - 6 . as shown in the exploded perspective view of fig1 , the present device 10 comprises a rigid container suitable for stand - alone use or for removable placement within a lunchbox , lunch bag or the like . the device includes a lower portion 12 , an upper portion 14 hingably connected to and sealingly engaging the lower portion 12 , and a hinged cover 16 secured to and sealingly engaging the upper portion 14 . the above components are molded from a rigid or semi - rigid plastic material , such as a polypropylene , polystyrene or polyurethane , and combinations thereof , to nest or press - fit within adjacent components . the lower portion 12 includes a base 18 and side walls 20 about the perimeter of the base . a series of inner walls 22 , along with the side walls 20 , define a plurality of lower compartments 24 within the lower portion 12 . three compartments are shown , but more or less compartments can be provided depending on the use requirements . the back end of each side wall 20 includes a raised portion or stop member 26 , each of which includes a hollowed portion or socket 28 along an interior surface thereof ( see fig6 ) or a through - bore ( see fig7 ) for receiving an upper portion hinge pin 30 as described herein . in particular , the back ends of opposite sides of the upper portion 14 include opposed cut - away portions 32 and hinge pins 30 for pivotal connection to corresponding opposed stop members 26 and sockets 28 of the side walls 24 of the lower portion 12 . the lower surface of the base 18 can include one or more hook - and - loop fastener strips 34 ( see fig6 ) for engaging a corresponding hook - and - loop fastener strip or strips positioned within the lunchbox or lunch bag . for example , four hook - and - loop fasteners can be used ( one adjacent each corner of the base 22 ) to engage corresponding hook - and - loop fasteners secured to the inner surface of a lunchbox or lunch bag . thus , the device can be releasably secured within the lunchbox or lunch bag , and readily removed for cleaning including placement in a dishwasher . the upper portion 14 includes a base 36 and side walls 38 about the perimeter of the base to form a compartment 40 . one or more inner walls ( not shown ) can be provided to define a number of compartments within the upper portion 14 , if desired . a recess 42 can be provided in the upper portion 14 to provide a fingerhold for engaging the edge of the cover 16 . likewise , a tab 44 can be provided in a side portion of the upper portion 14 to facilitate lifting and separating the upper portion 14 from the lower portion 12 . the base 36 of the upper portion 14 engages upper surfaces of the lower portion 12 to prevent the contents of one compartment from mixing with the contents of an adjacent compartment . a gasket 48 can be provided to enhance the connection and the seal between the upper and lower portions . if desired , a lower dividing panel 46 , which is preferably transparent , including the gasket 48 along its perimeter can be removably seated within the upper interior edges of the side walls 20 of the lower portion 12 to seal the compartments 24 of the lower portion 12 . a similar dividing panel , preferably transparent , and gasket can be provided to seal compartment ( s ) 40 of the upper portion 14 , if desired . in an alternative embodiment , one or both of the foregoing gaskets can be used without the dividing panels . in a further embodiment , no panel or gasket need be used . the back end of the cover 16 includes a pair of hinge pins 50 along the opposed sides thereof which are adapted to engage corresponding sockets 52 formed in the back ends of the side walls 38 of the upper portion 14 . thus , the cover 16 can be extended , relative to the upper portion 14 , from a closed position in which the cover sealingly engages the upper portion as shown in fig2 to an open position as shown in fig3 ( where a compartment 40 is accessible ). a clasp or other closure means ( not shown ) can be provided along an edge of the cover 16 and along one or more of the side walls 38 of the upper portion 14 to maintain the cover and the upper portion in a closed position . in a preferred embodiment as shown in fig4 and 5 , the stop members 26 along the back end of each side wall 20 of the lower portion 12 limit the maximum arc of travel of the upper portion 14 relative to the lower portion 12 to generally no more than about 120 degrees . the arc of travel can be as great as about 180 degrees , but should be at least about 90 degrees to provide easy access to the lower compartments of the container . one advantage of limiting the arc of travel of the upper portion 14 relative to the lower portion 12 to between about 90 degrees and about 120 degrees is the upper portion ( when opened ) is self - supported and does not engage the upper side walls of the lunchbox or lunch bag ( see fig3 ). the upper portion 14 can also include one or more compartments . fig3 shows an embodiment in which the upper portion 14 includes a single compartment large enough to hold a sandwich or the like . the device is shown removably secured within a soft - sided lunch bag 54 along with a beverage container 56 . access to the compartment ( s ) in the upper portion 14 is provided by lifting the hinged cover 16 and accessing the compartment ( s ) from the top . the maximum arc of travel of the cover 16 is similarly and preferably limited to between about 90 degrees and about 120 degrees based on the engagement ( or friction fit ) of the side or back edges of the cover 16 along the side or back upper surfaces of the upper portion 14 . this arrangement maintains the upper portion 14 in a substantively vertical position when the device is secured or positioned within the lunch bag 54 . in an alternative embodiment , the lower surface of the base 36 of the upper portion 14 and the top portions of the inner walls 22 of the lower portion 12 can cooperate to define a recess or cavity for receiving a cold pack or the like . the cold pack , of course , helps cool the contents of the upper and lower portions . in this embodiment , the lower dividing panel 46 would not be used or , if used , the lower dividing panel would preferably include a recessed portion as described herein with reference to fig7 - 13 . in use , the lower portion 12 can be used to store wet food items like cottage cheese , applesauce or pudding which are separated from the sandwich stored in the upper portion 14 . in particular , when the device is closed with lower dividing panel 46 in position , there is no transfer or leakage of food items from one compartment to the other within the lower portion 12 or from a food item in a compartment in the lower portion 12 to a food item in a compartment in the upper portion 14 . the container can also include a handle portion ( not shown ) secured to a side wall of either the lower portion 12 , the upper portion 14 , or both . this facilitates use of the device separate and apart from the lunchbox or lunch bag , if desired . in the alternative , the container can be used as a free - standing lunchbox without a handle . in a further embodiment , the outer surface ( s ) of the cover 16 and the outer surface of the base 18 can comprise generally flat panels which can be decorated , for example , with a washable paint , marker or the like . thus , the container can be decorated and the paint or markings can be easily removed by cleaning the container in a dishwasher . the washable paints or markers can be provided in kit form along with the device depending on how the product is packaged for distribution and sale . a second , and more preferred embodiment of the present invention is shown in fig7 -
