Abstract
Abstract A photographic film cartridge for insertion into a camera contains supply and takeup reel housings. A structurally weak area is provided adjacent the takeup reel housing. After the film has been exposed, the takeup reel housing may be separated from the remainder of the cartridge in order to permit more convenient handling and shipping of the exposed film.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
A film cartridge comprising a supply reel housing, a takeup reel housing, and an elongated aperture housing, said supply reel housing and said takeup reel housing being spaced from each other and joined to said aperture housing at opposite ends thereof, said takeup reel housing being joined to said aperture housing by a structurally weak junction, the cross section of said junction comprising substantially less material than the respective cross sections of the immediately adjacent portions of said takeup reel housing and said aperture housing, whereby said takeup reel housing may be readily separated from said aperture housing and said supply reel housing by breaking the material which forms said junction.
Claim 2
Dependent Claim
111 words
A film cartridge comprising a supply reel housing, a takeup reel housing, and an elongated aperture housing, said supply reel housing and said takeup reel housing being spaced from each other and joined to said aperture housing at opposite ends thereof, said takeup reel housing being joined to said aperture housing by a structurally weak junction, the cross section of said junction comprising substantially less material than the respective cross sections of the immediately adjacent portions of said takeup reel housing and said aperture housing, whereby said takeup reel housing may be readily separated from said aperture housing and said supply reel housing by breaking the material which forms said junction.
Claim 3
Dependent Claim
30 words
A film cartridge in accordance with claim 1 wherein the material of said junction is integral with the immediately adjacent portions of said takeup reel housing and said aperture housing.
Claim 4
Dependent Claim
25 words
A film cartridge in accordance with claim 2 wherein said junction is defined by a plurality of spaced openings in the material of said junction.
Claim 5
Dependent Claim
24 words
A film cartridge in accordance with claim 2 wherein said junction is defined by a plurality of grooves around the periphery of said junction.
Claim 6
Dependent Claim
55 words
A film cartridge in accordance with claim 1 wherein said junction comprises no material integral with the immediately adjacent portions of said takeup reel housing and said aperture housing, said immediately adjacent portions being joined by a web fixedly attached to said aperture housing and said takeup reel housing in overlying relation to said junction.
Claim 7
Dependent Claim
140 words
A film cartridge assembly comprising a supply reel, a takeup reel, a photographic film, said film extending between said supply and takeup reels, a supply reel housing, a takeup reel housing, and an elongated aperture housing, said supply reel housing and said takeup reel housing being spaced from each other and joined to said aperture housing at opposite ends thereof, said takeup reel housing being joined to said aperture housing by a structurally weak junction, the cross section of said junction comprising substantially less material than the respective cross sections of the immediately adjacent portions of said takeup reel housing and said aperture housing, whereby said takeup reel housing may be readily separated from said aperture housing and said supply reel housing by breaking the material forming said junction when all of said film is wound about said takeup reel.
Claim 8
Dependent Claim
140 words
A film cartridge assembly comprising a supply reel, a takeup reel, a photographic film, said film extending between said supply and takeup reels, a supply reel housing, a takeup reel housing, and an elongated aperture housing, said supply reel housing and said takeup reel housing being spaced from each other and joined to said aperture housing at opposite ends thereof, said takeup reel housing being joined to said aperture housing by a structurally weak junction, the cross section of said junction comprising substantially less material than the respective cross sections of the immediately adjacent portions of said takeup reel housing and said aperture housing, whereby said takeup reel housing may be readily separated from said aperture housing and said supply reel housing by breaking the material forming said junction when all of said film is wound about said takeup reel.
