Abstract
Abstract A light bulb container is made of a plastic foam material and includes a lower open topped receptacle portion with a downwardly opening top member pivotally connected to the receptacle portion along one edge thereof. The receptacle portion has a raised partition therein defining areas in which light bulbs can be received. The partition has a horizontal cross section defined by two continuous arcuate sections having their centers on opposite sides of the partition so that the partition continuously engages each light bulb in the container to prevent damage to the bulbs either from external or internal sources.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
282 words
A nestable container for light bulbs, said container comprising in combination: an open-topped receptacle of quadrangular horizontal cross-section having bottom and side walls, said receptacle side walls forming an angle with vertical so as to be downwardly convergent, a top member adapted to lie over the open top of said receptacle, said top member having a top wall and side walls, said top member side walls forming an angle with vertical so as to be upwardly convergent, a raised partition formed in said bottom wall of said receptacle having upwardly convergent sides defining an uppermost edge and opening downwardly to the bottom of said receptacle for defining separate light bulb receiving areas, said partition being generally S-shaped so that light bulbs placed in adjacent receiving areas are diametrically opposed, said uppermost edge of said partition extending to the height of said receptacle, tapering downwardly into ends level with said bottom wall, and terminating slightly short of the side ends of said bottom wall so that said light bulb positioned in one of said receiving areas engages said partition along the intermediate portion of said light bulb, means for hinging said top member to said receptacle along the corresponding rear side walls of said receptacle and said top member, and means for releasably connecting said top member with said receptacle along the front side walls of said container so that when said top member is connected to said receptacle the enlarged glass end of said light bulb frictionally engages said top wall, said bottom wall, and two side walls of said receptacle and the metallic contact end of said light bulb frictionally engages said bottom wall and one side wall of said receptacle.
Claim 2
Dependent Claim
282 words
A nestable container for light bulbs, said container comprising in combination: an open-topped receptacle of quadrangular horizontal cross-section having bottom and side walls, said receptacle side walls forming an angle with vertical so as to be downwardly convergent, a top member adapted to lie over the open top of said receptacle, said top member having a top wall and side walls, said top member side walls forming an angle with vertical so as to be upwardly convergent, a raised partition formed in said bottom wall of said receptacle having upwardly convergent sides defining an uppermost edge and opening downwardly to the bottom of said receptacle for defining separate light bulb receiving areas, said partition being generally S-shaped so that light bulbs placed in adjacent receiving areas are diametrically opposed, said uppermost edge of said partition extending to the height of said receptacle, tapering downwardly into ends level with said bottom wall, and terminating slightly short of the side ends of said bottom wall so that said light bulb positioned in one of said receiving areas engages said partition along the intermediate portion of said light bulb, means for hinging said top member to said receptacle along the corresponding rear side walls of said receptacle and said top member, and means for releasably connecting said top member with said receptacle along the front side walls of said container so that when said top member is connected to said receptacle the enlarged glass end of said light bulb frictionally engages said top wall, said bottom wall, and two side walls of said receptacle and the metallic contact end of said light bulb frictionally engages said bottom wall and one side wall of said receptacle.
Claim 3
Dependent Claim
66 words
The container of claim 1 wherein each corner of said receptacle is rounded and said container further comprises a continuous flange around the top perimeter of said receptacle and a continuous flange around the bottom perimeter of said top member so that when said top member covers said receptacle the abovesaid two flanges abut and protrude outwardly from said container encircling the mid-section of said container.
Claim 4
Dependent Claim
82 words
The container of claim 2 wherein said releasable connecting means comprises: an upwardly extending tab of generally trapezoidal configuration integrally and hingedly connected to said flange of said receptacle on said front wall, a forwardly protruding horizontally extending elongated bead formed along the longitudinal center axis of said tab, and an elongated opening conforming to the configuration of said bead in said front wall of said top member so that said bead engages said opening when said top member covers said receptacle.
Claim 5
Dependent Claim
13 words
The container of claim 3 wherein said container is formed from molded plastic.
Claim 6
Dependent Claim
71 words
The container of claim 1 wherein said top of said partition defines two continuous accurate portions of equal radius having their centers in opposing receiving areas, one side of each portion having a steep slope conforming to the surface of said enlarged glass end of said light bulb, and the opposite side of each portion having a shallow slope conforming to the surface of the contact end of said light bulb.
Claim 7
Dependent Claim
37 words
The container of claim 5 wherein said bottom wall is substantially flat and wherein the said partition opens upwardly in a narrow channel from said bottom wall, said channel being defined by the sides of said partition.
