Abstract
Abstract An internally located and essentially out-of-sight hinge construction for a two-piece container, each of the container pieces having a pair of hinge sockets provided with locking slots, the adjacent hinge sockets of the container pieces being interconnected by one-piece flexible plastic hinge straps having at the ends thereof wedgelike protuberances adapted to be engaged with the locking slots. The hinge straps are provided with wall sections of minimal thickness constituting a pair of spaced, parallel hinge lines about which the respective integrated portions of each strap move relative to each other to permit opening and closing of the two-piece container through an angle somewhat in excess of 180*.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
130 words
A hinge construction for a two-piece container comprising a socket formed in the back wall of each of the two pieces of the container, said sockets being in alignment when the container is in closed condition and being in spaced-apart or offset parallel relation when the container is in substantially fully open condition, a flexible hinge strap having end portions and an intermediate portion, means securing the end portions of said strap within said sockets, and a pair of parallel, spaced-apart, hinge lines formed in the intermediate portion of said strap, said hinge lines being located within the outer boundaries of the container when it is in the closed condition but enabling noninterfering pivotal movement between the pieces of the container in their movement between fully open and closed conditions.
Claim 2
Dependent Claim
130 words
A hinge construction for a two-piece container comprising a socket formed in the back wall of each of the two pieces of the container, said sockets being in alignment when the container is in closed condition and being in spaced-apart or offset parallel relation when the container is in substantially fully open condition, a flexible hinge strap having end portions and an intermediate portion, means securing the end portions of said strap within said sockets, and a pair of parallel, spaced-apart, hinge lines formed in the intermediate portion of said strap, said hinge lines being located within the outer boundaries of the container when it is in the closed condition but enabling noninterfering pivotal movement between the pieces of the container in their movement between fully open and closed conditions.
Claim 3
Dependent Claim
72 words
The hinge construction of claim 1, said end portions comprising leg portions and said intermediate portion comprising a generally centrally located block portion and a pair of tapered yoke portions interconnecting said leg portions and said block portion, said yoke portions being outwardly and angularly directed from said leg portions to said block portion and having their thinnest sections at their junctures with said block portion, said junctures constituting said hinge lines.
