Description
- This patent application is related to Provisional Application Ser. No. 61/281,620, filed Nov. 20, 2009, and Provisional Application Ser. No. 61/288,056, filed Dec. 18, 2009.
- The present invention relates to a container with multiple compartments for storing food items and for use in conjunction with a lunchbox, lunch bags or other portable container. The container can also be used as a stand-alone lunchbox that need not be used in conjunction with a lunchbox or insulated lunch bag.
- Various configurations of portable food containers have been developed over the years. See, for example—U.S. Pat. No. 5,462,192 to Pomroy et al. which discloses a lunch holder for carrying a plurality of food products; and U.S. Pat. No. 5,595,302 to Maydwell et al. which relates to a lunchbox including multiple compartments for storing food items, school supplies and dental hygiene materials.
- Neither of those products are suitable for removable, but secure, insertion within a lunchbox or lunch bag. There is a need for a versatile, multi-compartment container that can be used alone or in combination with a lunchbox or lunch bag to store food items in a sanitary and readily accessible manner.
- Lunch boxes are currently available in metal or plastic. Lunch bags, on the other hand, which are currently in common use are usually made of an insulated, water-resistant, polyester. Food items stored in a polyester lunch bag can be easily crushed. Also, if food items leak within the lunch bag, the bag can be difficult to clean and susceptible to mold or bacterial growth. Thus, there is a need for a rigid compact food container that can be secured within a lunch bag to protect food items and yet can be easily removed for cleaning. Such a container would also eliminate the need for using disposable plastic bags.
- The present invention relates to a multi-compartment food storage container adapted for use in a lunchbox, lunch bag or the like. The container can also be used as a stand-alone lunchbox that does not need to be inserted into a lunchbox or insulated lunch bag. The container includes a lower portion defining a plurality of compartments, and an upper portion pivotably connected to the lower portion. The upper portion defines at least one compartment and includes a hingably connected cover. The compartments are suitable for storing food items in a sanitary manner. The upper and lower portions press-fit, one within the other, and can be molded from a rigid or semi-rigid plastic material, such as a polypropylene, polystyrene or polyurethane, and combinations thereof. The container eliminates the need to use disposable plastic bags.
- In a preferred embodiment, the present invention relates to a rigid storage container for use in combination with a lunchbox or lunch bag, the container comprising a lower portion defining at least one compartment for holding a food item; an upper portion defining at least one compartment for holding additional food items, the upper portion being hingably connected to the lower portion for movement from a closed position to an open position; and a cover hingably connected to the upper portion for movement from a closed position to an open position, whereby the upper portion effectively seals the lower portion when the upper portion is in the closed position and the cover effectively seals the upper portion when the cover is in the closed position. Stop means associated with the upper portion and the lower portion defines the maximum arc of travel of the upper portion relative to the lower portion from the closed position to the open position within a range of about 90 degrees to about 120 degrees. Stop means associated with the cover and the upper position can also be provided to limit the maximum arc of travel of the cover relative to the upper portion from the closed position to the open position within a range of about 90 degrees to about 120 degrees. In an alternative embodiment, a removable panel can be included to separate the upper portion from the lower portion, and a similar removable panel can be used to separate the cover from the upper portion. Hook-and-loop fastening means, or the like, can removably secure the container within the lunchbox or lunch bag.

FIGS. 1-6 . As shown in the exploded perspective view ofFIG. 1 , thepresent 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 alower portion 12, anupper portion 14 hingably connected to and sealingly engaging thelower portion 12, and a hingedcover 16 secured to and sealingly engaging theupper 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 abase 18 andside walls 20 about the perimeter of the base. A series ofinner walls 22, along with theside walls 20, define a plurality oflower compartments 24 within thelower portion 12. Three compartments are shown, but more or less compartments can be provided depending on the use requirements. The back end of eachside wall 20 includes a raised portion orstop member 26, each of which includes a hollowed portion or socket 28 along an interior surface thereof (seeFIG. 6 ) or a through-bore (seeFIG. 7 ) for receiving an upperportion hinge pin 30 as described herein. In particular, the back ends of opposite sides of theupper portion 14 include opposed cut-away portions 32 andhinge pins 30 for pivotal connection to correspondingopposed stop members 26 and sockets 28 of theside walls 24 of thelower portion 12. - The lower surface of the
base 18 can include one or more hook-and-loop fastener strips 34 (seeFIG. 6 ) 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 abase 36 andside walls 38 about the perimeter of the base to form acompartment 40. One or more inner walls (not shown) can be provided to define a number of compartments within theupper portion 14, if desired. Arecess 42 can be provided in theupper portion 14 to provide a fingerhold for engaging the edge of thecover 16. Likewise, atab 44 can be provided in a side portion of theupper portion 14 to facilitate lifting and separating theupper portion 14 from thelower portion 12. - The
base 36 of theupper portion 14 engages upper surfaces of thelower portion 12 to prevent the contents of one compartment from mixing with the contents of an adjacent compartment. Agasket 48 can be provided to enhance the connection and the seal between the upper and lower portions. If desired, alower dividing panel 46, which is preferably transparent, including thegasket 48 along its perimeter can be removably seated within the upper interior edges of theside walls 20 of thelower portion 12 to seal thecompartments 24 of thelower portion 12. A similar dividing panel, preferably transparent, and gasket can be provided to seal compartment(s) 40 of theupper 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 theside walls 38 of theupper portion 14. Thus, thecover 16 can be extended, relative to theupper portion 14, from a closed position in which the cover sealingly engages the upper portion as shown inFIG. 2 to an open position as shown inFIG. 3 (where acompartment 40 is accessible). A clasp or other closure means (not shown) can be provided along an edge of thecover 16 and along one or more of theside walls 38 of theupper portion 14 to maintain the cover and the upper portion in a closed position. - In a preferred embodiment as shown in
FIGS. 4 and 5 , thestop members 26 along the back end of eachside wall 20 of thelower portion 12 limit the maximum arc of travel of theupper portion 14 relative to thelower 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 theupper portion 14 relative to thelower 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 (seeFIG. 3 ). - The
upper portion 14 can also include one or more compartments.FIG. 3 shows an embodiment in which theupper 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 abeverage container 56. Access to the compartment(s) in theupper portion 14 is provided by lifting the hingedcover 16 and accessing the compartment(s) from the top. The maximum arc of travel of thecover 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 thecover 16 along the side or back upper surfaces of theupper portion 14. This arrangement maintains theupper portion 14 in a substantively vertical position when the device is secured or positioned within thelunch bag 54. - In an alternative embodiment, the lower surface of the
base 36 of theupper portion 14 and the top portions of theinner walls 22 of thelower 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, thelower 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 toFIGS. 7-13 . - 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 theupper portion 14. In particular, when the device is closed withlower dividing panel 46 in position, there is no transfer or leakage of food items from one compartment to the other within thelower portion 12 or from a food item in a compartment in thelower portion 12 to a food item in a compartment in theupper portion 14. - The container can also include a handle portion (not shown) secured to a side wall of either the
lower portion 12, theupper 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
FIGS. 7-13 . As in the first embodiment described herein, thedevice 60 comprises a rigid container including alower portion 62, anupper portion 64 hingably connected to thelower portion 62, and a hingedcover 66 secured to theupper portion 64. The foregoing components are molded to nest or press-fit together so that the upper portion can sealingly engage the lower portion and the cover can sealingly engage the upper portion. - The
lower portion 62 includes a base 68 andside walls 70 about the perimeter of the base. A series ofinner walls 72, along with theside walls 70, define a plurality of lower compartments 74 (seeFIG. 13 ) within thelower portion 62. Three compartments are shown, but more or less compartments can be provided. The back end of eachside wall 70 includes a raised portion or stopmember 76, each of which includes a bore 78 (seeFIG. 7 ) for receiving an upperportion hinge pin 80 as described herein. In particular, the back ends of opposite sides of theupper portion 64 include opposed cut-awayportions 82 and bores 84 for receipt of the corresponding hinge pins 80 for pivotal connection relative to correspondingopposed stop members 76 and bores 78 of theside walls 70 of thelower portion 62. - The lower surface of the base 68 can include one or more hook-and-loop fastener strips 86 (see
FIG. 13 ) for engaging a corresponding hook-and-loop fastener strip or strips positioned within the lunchbox or lunch bag. Thus, as described above with reference toFIG. 6 , 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 64 includes abase 88 andside walls 90 about the perimeter of the base to form a compartment 92. One or more inner walls (not shown) can be provided to define a number of compartments within theupper portion 64, if desired. - A
lower dividing panel 94, which is preferably transparent, including agasket 96 along its perimeter can be removably seated within the upper interior edges of theside walls 70 of thelower portion 62 to seal thecompartments 74 of thelower portion 62 and prevent the contents of one compartment from mixing with the contents of another compartment. If desired, thelower dividing panel 94 can includeadditional partition members 98 andgaskets 100 to maintain separation between the compartments, as shown more clearly inFIG. 13 . A similar dividing panel 102, also preferably transparent, and gasket 104 can be provided to seal compartment(s) 92 of theupper portion 64, if desired. As described above with reference toFIGS. 1-6 , the dividing panels and gaskets are optional. - The back end of the
cover 66 includes a pair of hinge pins 106 along the opposed sides thereof which are adapted to engage correspondingbores 108 formed in the back ends of theside walls 90 of theupper portion 64 and thecover 66. Thus, thecover 66 can be extended, relative to theupper portion 64, from a closed position as shown inFIG. 8 to an open position as shown inFIG. 9 (where a compartment 92 is accessible). Alatch 110 or other closure means including aslot 112 can be provided along an edge of thecover 66 to engage acatch 114 along one of theside walls 90 of theupper portion 64 to maintain the cover and the upper portion in a closed position. Similarly, alatch 116 or other closure means including aslot 118 can be provided along aside wall 90 of theupper portion 64 to engage acatch 120 along acorresponding side wall 70 of thelower portion 62 to maintain the upper and lower portions in a closed position. Other closure means, as known in the art, can be used. - In a preferred embodiment as shown in
FIGS. 10 and 11 , thestop members 76 along the back end of eachside wall 70 of thelower portion 62 limit the maximum arc of travel of theupper portion 64 relative to thelower portion 62 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 theupper portion 64 relative to thelower portion 62 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. - The
upper portion 64 can also include one or more compartments.FIG. 9 shows an embodiment in which theupper portion 64 includes a single compartment large enough to hold a sandwich or the like. Access to the compartment(s) in theupper portion 64 is provided by lifting the hingedcover 66 and accessing the compartment(s) from the top. The maximum arc of travel of thecover 66 is similarly and preferably limited to between about 90 degrees and about 120 degrees based on the engagement of the back edge of thecover 66 along the back upper surface of theupper portion 64. - In an alternative embodiment, the lower surface of the
base 88 of theupper portion 64 can include an upwardly extending recess (relative to the horizontal plane of connection between the upper and lower portions) and the top portions of theinner walls 72 of thelower portion 62 can include a downwardly extending recess or space to define a cavity for receiving a cold pack or the like to cool the contents of the upper and lower portions. In this embodiment, thelower dividing panel 94, if used, would preferably include a recessed portion to correspond to the shape of the downwardly extending recess or space defined in thelower portion 62. - In use, the
lower portion 62 can be used to store wet food items like cottage cheese, applesauce or pudding which are separated from the sandwich stored in theupper portion 64. SeeFIG. 12 . In particular, when the device is closed with thelower dividing panel 94 in position, there is no transfer or leakage of food items from one compartment to the other within thelower portion 62 or from a food item in a compartment in thelower portion 62 to a food item in a compartment in theupper portion 64. - The container can also include a handle 122 secured to a side wall of either the
lower portion 62, theupper portion 64, or both. The handle 122 includes handle pins 124 at each end thereof which engageopenings 126 defined in a pair of handle yokes 128. 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. - The foregoing description and drawings of the present invention are illustrative and are presented by way of example. As will be appreciated by those skilled in the art of container design and manufacture, various modifications can be made in the configuration and construction of the invention without departing from the spirit and scope thereof.
