Abstract
Abstract A photographic film assemblage including a container for holding film units, having a forward wall with a light-transmitting section therein and an end wall cooperating with the forward wall to define a withdrawal opening; a plurality of film units stacked within the container with one of the film units located in alignment with the withdrawal opening; and a stop in the form of an integral extension of the end wall extending part way across the withdrawal opening to prevent the movement of more than one film unit at a time from the container through the withdrawal opening.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
15 words
A photographic film assemblage as defined in claim 1 wherein said stop member is resilient.
Claim 2
Dependent Claim
16 words
A photographic film assemblage as defined in claim 1 wherein said container is of unitary construction.
Claim 3
Dependent Claim
61 words
A photographic film assemblage as defined in claim 1 wherein said forward wall includes an aperture therein located adjacent one side thereof intermediate said light-transmitting section and said opening for receiving means for engaging said forwardmost film unit and moving the latter through said opening, said stop means being located near the end of said opening most remote from said aperture.
Claim 4
Dependent Claim
56 words
A photographic film assemblage as defined in claim 1 wherein said stop member comprises an extended section of said end wall, extending across said opening toward forward wall, said end wall being formed with slits extending away from said opening adjacent each side of said extended section thereby increasing the effective length of said extended section.
Claim 5
Dependent Claim
235 words
A container for holding a plurality of photographic film units, said container comprising, in combination: spaced forward and rear walls; sidewalls and a first end wall formed integrally with said forward and rear walls to define a chamber for receiving a plurality of film units, said forward wall having a light-transmitting section therein for admitting light to said chamber to expose a film unit located therewithin behind said forward wall; a second end wall initially formed adjacent an end edge of said rear wall as an extension thereof and in a plane substantially parallel with one of said forward and rear walls; and hinge means connecting said second end wall to said rear wall at said edge thereof, said hinge means comprising a narrow wall section integral with said second end wall and located at said edge of said rear wall, having a thickness less than the thickness of said second end wall and said rear wall for providing a high degree of flexibility to said narrow wall section; said second end wall being folded at said section into a position wherein said second end wall is generally perpendicular to said forward wall and lies substantially in a plane containing said edge, said second end wall being secured to the ends of said sidewalls and cooperating with said forward wall to define an elongated opening dimensioned to permit the passage of a film unit therethrough.
Claim 6
Dependent Claim
31 words
A container as defined in claim 6 wherein said hinge means comprise a plurality of said wall sections of reduced thickness aligned with one another and separated by narrow, aligned openings.
Claim 7
Dependent Claim
51 words
A container as defined in claim 6 wherein said second end wall is formed with an integral projection extending beyond the edge of said second end wall part way across said elongated opening to provide means for preventing more than one film unit at a time from moving through said opening.
