Abstract A lunchbox including a heat-insulating housing and a first container within the housing and in close-fitting engagement therewith. A second container adapted to contain food is suspended in the first container with its bottom spaced above the bottom of the first container to provide space for storing liquid. A faucet outside the first container communicates with the liquid compartment. The second container has a close-fitting cover and the housing has a removable cover. The housing cover has its bottom surface spaced from the second container cover to provide an additional compartment for food or utensils.

Total Claims: 9
Claim 1
Independent Claim
491 words
A receptacle device for carrying food and beverage products comprising, a hollow housing formed entirely of generally rigid, polymeric foam material, said housing being defined by generally flat integrally connected side, end and bottom walls including upper ends which together form an endless peripheral shoulder defining an open top for said housing, a hollow cover member detachably mounted on said housing being formed entirely of generally rigid, polymeric foam material and including side and end walls adapted for seated engagement on said peripheral shoulder of said housing and defining with said housing an enclosed insulated storage chamber in the installed position thereof, an open-top first container made of heat-conductive material including side, end and bottom walls adapted to be received through the open top of said housing, said first container slidably inserted in formfitted relation within the interior of said housing having the side, end and bottom walls thereof disposed in close-fitting contact with the corresponding side, end and bottom walls of said housing, a foreshortened, open-top second container made of heatconductive material including side, end and bottom walls adapted to be received through the open top of said first container, said second container slidably inserted and suspended in partially formfitted relation within the interior of said first container having the side and end walls thereof disposed in close-fitting contact with the corresponding side and end walls of said first container and having its bottom wall spaced above said bottom wall of said first container to define a beverage product storage space therebetween, a coverlike container made of heat-conductive material including side, end and bottom walls adapted to be received through the open top of said second container, said coverlike container being foreshortened with respect to said second container and suspended in partially formfitted relation adjacent the open top of said second container having its bottom wall spaced above said bottom wall of said second container defining a food product storage space therebetween, each of said containers including laterally extending, peripheral flanges projecting outwardly therefrom adjacent said open top thereof, said flanges being of a complementary-shaped configuration for inner fitting seated engagement with one another in the installed position thereof to provide a seal between the respective food and beverage products storage spaces, said cover member including recessed portions to provide clearance above said coverlike container to provide additional food products storage space, the wall thickness of said cover member being less than the wall thickness of said housing adjacent said shoulder forming an insetlike support surface for seatingly supporting said flange of said first container, said cover member and said support surface clampingly coacting with one another to clamp said flanges in interlocking relation in the installed position of said containers and said cover member, and a faucet assembly mounted on the exterior of said housing and connecting the exterior of said device in fluid communication with said beverage product Storage space for dispensing said beverage product from said device.
Claim 2
Dependent Claim
491 words
A receptacle device for carrying food and beverage products comprising, a hollow housing formed entirely of generally rigid, polymeric foam material, said housing being defined by generally flat integrally connected side, end and bottom walls including upper ends which together form an endless peripheral shoulder defining an open top for said housing, a hollow cover member detachably mounted on said housing being formed entirely of generally rigid, polymeric foam material and including side and end walls adapted for seated engagement on said peripheral shoulder of said housing and defining with said housing an enclosed insulated storage chamber in the installed position thereof, an open-top first container made of heat-conductive material including side, end and bottom walls adapted to be received through the open top of said housing, said first container slidably inserted in formfitted relation within the interior of said housing having the side, end and bottom walls thereof disposed in close-fitting contact with the corresponding side, end and bottom walls of said housing, a foreshortened, open-top second container made of heatconductive material including side, end and bottom walls adapted to be received through the open top of said first container, said second container slidably inserted and suspended in partially formfitted relation within the interior of said first container having the side and end walls thereof disposed in close-fitting contact with the corresponding side and end walls of said first container and having its bottom wall spaced above said bottom wall of said first container to define a beverage product storage space therebetween, a coverlike container made of heat-conductive material including side, end and bottom walls adapted to be received through the open top of said second container, said coverlike container being foreshortened with respect to said second container and suspended in partially formfitted relation adjacent the open top of said second container having its bottom wall spaced above said bottom wall of said second container defining a food product storage space therebetween, each of said containers including laterally extending, peripheral flanges projecting outwardly therefrom adjacent said open top thereof, said flanges being of a complementary-shaped configuration for inner fitting seated engagement with one another in the installed position thereof to provide a seal between the respective food and beverage products storage spaces, said cover member including recessed portions to provide clearance above said coverlike container to provide additional food products storage space, the wall thickness of said cover member being less than the wall thickness of said housing adjacent said shoulder forming an insetlike support surface for seatingly supporting said flange of said first container, said cover member and said support surface clampingly coacting with one another to clamp said flanges in interlocking relation in the installed position of said containers and said cover member, and a faucet assembly mounted on the exterior of said housing and connecting the exterior of said device in fluid communication with said beverage product Storage space for dispensing said beverage product from said device.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
43 words
A receptacle device in accordance with claim 1, wherein the height of said second container is less than the height of said first container to provide a relatively low center of gravity for said housing when said beverage product storage space is occupied.
Claim 5
Dependent Claim
26 words
A receptacle device in accordance with claim 3, wherein the height of said second container is more than half of the height of said first container.
Claim 6
Dependent Claim

Claim 8
Dependent Claim
50 words
A receptacle device in accordance with claim 1, wherein said cover member is of a generally inverted U-shaped configuration when viewed in vertical section, being defined by a pair of upwardly and outwardly tapered recess portions extending toward the opposed ends thereof to provide said clearance above said coverlike container.
Claim 9
Dependent Claim
67 words
A receptacle device in accordance with claim 1, wherein said flange of said first container is disposed in inner fitting locking relation within said flange of said second container, and said flange of said second container is disposed in inner fitted locking relation within said flange of said coverlike container to prevent relative movement with respect to said housing in the installed position of said cover member.
