Abstract
Abstract A blow molded container case has a main body portion, a lid and a lid hinge which pivotally mounts the lid to the main body portion. The main body portion includes top and bottom walls and side walls interposed between the top and bottom walls and interconnected thereto at corresponding peripheral edge portions thereof. The top wall has formed therein an opening for access to the interior of the main body portion. The opening is spaced inwardly from the periphery of the top wall. A portion of the top wall surrounding the opening is shaped to form a well to closely receive the lid. The lid receiving well includes an inner wall projecting downwardly from the top wall of the main body portion, a seat portion projecting inwardly from the inner wall and a rim extending downwardly from the seat portion. The seat portion is recessed below the upper surface of the top wall a distance which corresponds substantially to the thickness of the lid so that, when the lid is properly seated in the receiving well in a closed position, the outer surface of the lid lies substantially flush with the upper surface of the top wall. The lid hinge includes a pair of pin posts which respectively project outwardly from opposite sides of the lid and are positioned near adjacent corners of the lid. The posts are received by cooperating holes formed in corresponding portions of the lid receiving well.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
254 words
A container case formed by a blow molding process which comprises a one-piece blow molded main body portion, a separate one-piece blow molded lid and hinge means for pivotally mounting said lid to said main body portion, said main body portion including top and bottom walls and side walls interposed between said top and bottom walls and interconnected thereto at corresponding peripheral edge portions thereof, said top wall having formed therein an opening for access to the interior of said main body portion, said opening being spaced inwardly from the periphery of said top wall, a portion of said top wall surrounding said opening being shaped to form a well to closely receive said lid, said lid receiving well including an inner wall projecting downwardly from said top wall of the main body portion, a seat portion projecting inwardly from said inner wall and a rim projecting downwardly from the seat portion, said seat portion being recessed below the upper surface of said top wall a distance which corresponds substantially to the thickness of said lid so that, when said lid is properly seated in said receiving well in a closed position, the outer surface of said lid lies substantially flush with the upper surface of said top wall, at least one of the side walls of said main body portion including a base having a central portion and edge portions which mutually diverge from said central portion to increase the stability of the container case when the container case rests on said base.
Claim 2
Dependent Claim
254 words
A container case formed by a blow molding process which comprises a one-piece blow molded main body portion, a separate one-piece blow molded lid and hinge means for pivotally mounting said lid to said main body portion, said main body portion including top and bottom walls and side walls interposed between said top and bottom walls and interconnected thereto at corresponding peripheral edge portions thereof, said top wall having formed therein an opening for access to the interior of said main body portion, said opening being spaced inwardly from the periphery of said top wall, a portion of said top wall surrounding said opening being shaped to form a well to closely receive said lid, said lid receiving well including an inner wall projecting downwardly from said top wall of the main body portion, a seat portion projecting inwardly from said inner wall and a rim projecting downwardly from the seat portion, said seat portion being recessed below the upper surface of said top wall a distance which corresponds substantially to the thickness of said lid so that, when said lid is properly seated in said receiving well in a closed position, the outer surface of said lid lies substantially flush with the upper surface of said top wall, at least one of the side walls of said main body portion including a base having a central portion and edge portions which mutually diverge from said central portion to increase the stability of the container case when the container case rests on said base.
