Abstract
Abstract A pack embodying conventional photographic film, in the form of a strip thereof, has such strip so folded and joined that the various exposure sections of the film strip may be successively uncovered in the exposure aperture of the pack, by means of respective pull tabs. The exposed film sections are successively drawn into a storage section within the pack by means of the pull tabs; and such film is stored in the pack in strip form to facilitate subsequent handling thereof. The pack may be employed in cameras of the instant processing-type.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
A photographic film pack having an exposure aperture therein, and containing divider means for separating said pack into an exposure compartment and a film storage compartment, said storage compartment having an aperture therein, the film in said pack being in strip form and so disposed within said pack that when a first exposure section of the film strip is within the said exposure aperture, a second exposure section of the film strip is covered by the first exposure section, the two exposure sections being cooperative with each other to form a Z-fold with a diagonal residing therebetween, said diagonal being joined edgewise to the said first exposure section, a first pull tab releasably joined to the end of said first exposure section to which the said diagonal is not attached, and a second pull tab releasably joined to the end of said second film section to which said diagonal is attached, the second pull tab being joined to the first pull tab, and said first pull tab being adapted to be drawn through the aperture in said storage compartment.
Claim 2
Dependent Claim
179 words
A photographic film pack having an exposure aperture therein, and containing divider means for separating said pack into an exposure compartment and a film storage compartment, said storage compartment having an aperture therein, the film in said pack being in strip form and so disposed within said pack that when a first exposure section of the film strip is within the said exposure aperture, a second exposure section of the film strip is covered by the first exposure section, the two exposure sections being cooperative with each other to form a Z-fold with a diagonal residing therebetween, said diagonal being joined edgewise to the said first exposure section, a first pull tab releasably joined to the end of said first exposure section to which the said diagonal is not attached, and a second pull tab releasably joined to the end of said second film section to which said diagonal is attached, the second pull tab being joined to the first pull tab, and said first pull tab being adapted to be drawn through the aperture in said storage compartment.
Claim 3
Dependent Claim
85 words
The pack of claim 1 including an opaque cover sheet, said cover sheet being adapted to occupy the exposure aperture of said pack before any exposures of the film sections within said pack have been made, said opaque cover sheet having a pull tab releasably secured to it and drawn through the aperture in said storage compartment, the pull tab for the first exposure section of said film strip being releasably secured, within the pack, to the pull tab for the said opaque cover sheet.
Claim 4
Dependent Claim
110 words
The pack of claim 1 wherein a. said divider means has releasably secured thereto the ends of said exposure sections which do not have metering strips secured to them, and b. said pack includes guide means within the storage compartment of said pack and having a cradle for receiving the exposure sections of said film strip which are drawn into said storage compartmenT, said guide means having an opening therein through which said pull tabs are adapted to be drawn, said opening being in communication with the aperture in said storage compartment, the width of said opening, and said pull tabs, being narrower than the width of said exposure sections.
Claim 5
Dependent Claim
125 words
The apparatus of claim 3 including an opaque cover sheet releasably secured to said divider means, said cover sheet being adapted to occupy the exposure aperture of said pack before any exposures of the film sections within said pack have been made, said opaque cover sheet being substantially as wide as said exposure sections and having a pull tab narrower than said guide opening and said aperture in said storage compartment, said cover sheet pull tab being releasably secured to said cover sheet and drawn through the guide opening and through the aperture in said storage compartment, the pull tab for the first exposure section of said film strip being releasably secured, within the pack, to the pull tab for the said opaque cover sheet.
Claim 6
Dependent Claim
133 words
The pack of claim 4 including a second opaque sheet substantially as wide as the said cover sheet, said second opaque sheet having a first part in said exposure compartment, said first part being releasably secured to said divider means and being so disposed within the pack that said cover sheet and said opaque first part sandwich said Z-folded film strip between them when said cover sheet is within the exposure aperture of the pack, said second opaque sheet also having a second part which is wrapped around said divider means and disposed to reside between said divider means and said guide means, said second part having a pull tab releasably secured to it, and to the pull tab for the last exposure section which is adapted to reside in said exposure section.
Claim 7
Dependent Claim
49 words
The pack of claim 5 wherein said divider means includes first and second means for respectively urging the parts of said film strip in said exposure and storage compartments away from said divider means, and said divider means being positionable within said pack with respect to said exposure aperture.
Claim 8
Dependent Claim
35 words
The pack of claim 6 wherein the cradle of said divider means is formed in a member that is forked to define an opening having a width narrower than the width of said exposure sections.
Claim 9
