Film cartridge

Claim 2

A film cartridge adapted to nest with adjacent similar film cartridges, said film cartridge comprising: means for defining a generally cylindrical film compartment comprising a side wall and opposed end walls connected to said side wall; a film winding core rotatably mounted within said compartment; means, including a gear member connected to said core, for rotating said core; means carried by one of said end walls for accommodating said gear member, said means including a gear cover extending outwardly from said one end wall; and means carried by the other of said end walls for defining a recess configured to receive the gear cover of an adjacent similar cartridge to facilitate nesting of the cartridges.

Claim 3

A film cartridge adapted to be compactly stacked with other film cartridges, said film cartridge comprising: a rotatable core for winding filmstrip therearound, said core having oppositely disposed end portions; a gear supported by the core at one of said end portions for imparting rotation to said core to wind filmstrip on said core; means defining a compartment for housing said core and dimensioned to house filmstrip wound on said core, said compartment having opposed end walls, one of said end walls being located adjacent said one end portion; a cover partially enclosing said gear and extending outwardly beyond said one end wall; a recess in the other of said end walls, said recess being configured to receive the cover of an adjacent cartridge to facilitate the compact stacking of the cartridges.

Claim 4

A film cartridge adapted to be compactly stacked with other film cartridges, said film cartridge comprising: a rotatable core for winding filmstrip therearound, said core having oppositely disposed end portions; a gear supported by the core at one of said end portions for imparting rotation to said core to wind filmstrip on said core; means defining a compartment for housing said core and dimensioned to house filmstrip wound on said core, said compartment having opposed end walls, one of said end walls being located adjacent said one end portion; a cover partially enclosing said gear and extending outwardly beyond said one end wall; a recess in the other of said end walls, said recess being configured to receive the cover of an adjacent cartridge to facilitate the compact stacking of the cartridges.

Claim 5

A film cartridge comprising: a take-up compartment including means defining a take-up chamber and oppositely disposed end walls, and having a longitudinal axis and a predetermined diameter; a rotatably mounted core in said take-up chamber, said core having a driven end and being generally coaxial with said axis; a circular gear for rotating said core, said gear being fixed on the driven end of said core and substantially concentrically disposeD in said take-up chamber, said gear having a diameter less than the diameter of said take-up compartment; a cover on one of said end walls for said gear, said cover having a width less than the diameter of said take-up compartment; and means defining a recess in the other of said end walls, said recess being configured to receive the cover of an adjacent film cartridge.

Claim 6

A film cartridge comprising: a take-up compartment including means defining a take-up chamber and oppositely disposed end walls, and having a longitudinal axis and a predetermined diameter; a rotatably mounted core in said take-up chamber, said core having a driven end and being generally coaxial with said axis; a circular gear for rotating said core, said gear being fixed on the driven end of said core and substantially concentrically disposeD in said take-up chamber, said gear having a diameter less than the diameter of said take-up compartment; a cover on one of said end walls for said gear, said cover having a width less than the diameter of said take-up compartment; and means defining a recess in the other of said end walls, said recess being configured to receive the cover of an adjacent film cartridge.

Claim 7

A film cartridge according to claim 3, said cartridge further including a spindle extending inwardly into the take-up chamber from the end wall in which said recess is defined; said core being mounted for rotation on said spindle; and said spindle being integral with said recess defining means to form a light impervious structure.

Claim 8

A film cartridge operable to nest with adjacent similar film cartridges to facilitate the compact stacking thereof, said cartridge comprising: means for defining a film compartment including a side wall and opposed end walls connected to said side wall, one of said end walls having an opening extending therethrough; a film winding core rotatably mounted within said compartment; means, including a member connected to said core and protruding through said opening and outwardly beyond said one side wall, for rotating said core; and means, including an inwardly-extending recess carried by the other of said end walls, for receiving therein the protruding core-rotating member of a similar cartridge to facilitate the compact stacking of said cartridges.

Claim 9

A film cartridge operable to nest with adjacent similar film cartridges to facilitate the compact stacking thereof, said cartridge comprising: means for defining a film compartment including a side wall and opposed end walls connected to said side wall, one of said end walls having an opening extending therethrough; a film winding core rotatably mounted within said compartment; means, including a member connected to said core and protruding through said opening and outwardly beyond said one side wall, for rotating said core; and means, including an inwardly-extending recess carried by the other of said end walls, for receiving therein the protruding core-rotating member of a similar cartridge to facilitate the compact stacking of said cartridges.
