Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
A container for light-sensitive strip material, said container comprising: a body member having (1) a central cavity, (2) a opening through which strip material is loaded into the cavity and (3) a slot through which the leader of the strip material extends when the strip material is loaded in the cavity; a cover engagable with said body member to close the opening after the strip material is loaded in the cavity; a slot closure member movable in said slot between a slot-open position and a slot-closed position, said closure member being biased to its slot-open position for receiving the leader of strip material loaded in the cavity; and cooperative means on said cover and said closure member for moving said closure member to its slot-closed position as said cover closes the opening in said body member.
Claim 2
Dependent Claim
136 words
A container for light-sensitive strip material, said container comprising: a body member having (1) a central cavity, (2) a opening through which strip material is loaded into the cavity and (3) a slot through which the leader of the strip material extends when the strip material is loaded in the cavity; a cover engagable with said body member to close the opening after the strip material is loaded in the cavity; a slot closure member movable in said slot between a slot-open position and a slot-closed position, said closure member being biased to its slot-open position for receiving the leader of strip material loaded in the cavity; and cooperative means on said cover and said closure member for moving said closure member to its slot-closed position as said cover closes the opening in said body member.
Claim 3
Dependent Claim
17 words
A container as set forth in claim 1 wherein said slot extends to said body member opening.
Claim 4
Dependent Claim
122 words
A container for light-sensitive strip material, said container comprising: a body member having (1) a central cavity, (2) an opening through which strip material is loaded into the cavity and (3) a slot through which the leader of the strip material extends when the strip material is loaded in the cavity; a cover engagable with said body member to close the opening after the strip material is received in the cavity; a closure member movable in said slot between a slot-open position and a slot-closed position; and a cam surface on said cover, engagable with said closure member, for moving said closure member to its slot-closed position as said cover engages said body member to close the opening in said body member.
Claim 5
Dependent Claim
122 words
A container for light-sensitive strip material, said container comprising: a body member having (1) a central cavity, (2) an opening through which strip material is loaded into the cavity and (3) a slot through which the leader of the strip material extends when the strip material is loaded in the cavity; a cover engagable with said body member to close the opening after the strip material is received in the cavity; a closure member movable in said slot between a slot-open position and a slot-closed position; and a cam surface on said cover, engagable with said closure member, for moving said closure member to its slot-closed position as said cover engages said body member to close the opening in said body member.
Claim 6
Dependent Claim
123 words
A container for a roll of light-sensitive strip material, said container comprising: a body member having (1) a central cavity, (2) an opening through which a strip material roll is received into the cavity and (3) a slot through which the leader of the strip material extends when the roll is received in the cavity; a cover engagable with said body member to close the opening after the roll is received in the cavity; a closure member pivotably movable in said slot between a slot-open position and a slot-closed position; and cooperative means on said cover and said closure member for pivoting said closure member to its slot-closed position as said cover engages said body member to the opening in the body member.
Claim 7
Dependent Claim
123 words
A container for a roll of light-sensitive strip material, said container comprising: a body member having (1) a central cavity, (2) an opening through which a strip material roll is received into the cavity and (3) a slot through which the leader of the strip material extends when the roll is received in the cavity; a cover engagable with said body member to close the opening after the roll is received in the cavity; a closure member pivotably movable in said slot between a slot-open position and a slot-closed position; and cooperative means on said cover and said closure member for pivoting said closure member to its slot-closed position as said cover engages said body member to the opening in the body member.
Claim 8
Dependent Claim
139 words
A container for a roll of light-sensitive strip material, said container comprising: four walls forming a rectangular body member having a central cavity with at least one open end for receiving the roll, one of said walls having a slot in communication with the one open end of said body member so that the leader of the strip material can be laterally threaded into the slot as the roll is received in the cavity; a cover engagable with said body member to close the open end after the roll is received in the cavity; a closure member pivotably movable in the slot between a slot-open position and a slot-closed position; and cooperative means on said cover and said closure member for moving said closure member to its slot-closed position as said cover closes the opening in said body member.

Dependent Claim
139 words
A container for a roll of light-sensitive strip material, said container comprising: four walls forming a rectangular body member having a central cavity with at least one open end for receiving the roll, one of said walls having a slot in communication with the one open end of said body member so that the leader of the strip material can be laterally threaded into the slot as the roll is received in the cavity; a cover engagable with said body member to close the open end after the roll is received in the cavity; a closure member pivotably movable in the slot between a slot-open position and a slot-closed position; and cooperative means on said cover and said closure member for moving said closure member to its slot-closed position as said cover closes the opening in said body member.
Claim 10
Dependent Claim
36 words
A container as set forth in claim 5 wherein said one wall has a channel therein and said closure member is received in the channel and slidably movable therein between its slot-opened position and slot-closed position.
Claim 11
Dependent Claim
147 words
A container for light-sensitive strip material, said container comprising: a body member having (1) a central cavity, (2) an open end for receiving the strip material in said body member, and (3) a slot for receiving the leader of strip material received by the cavity through the open end of the body member; a cover engagable with said body member to close the open end after the strip material is loaded in the cavity; a closure member movable in the slot between a slot-open position and a slot-closed position, said closure member having a center of gravity so as to be gravity urged toward its slot-open position when the open end of said body member is facing upwardly; and cooperative means on said cover and said closure member for moving said closure member to its slot-closed position as said cover closes the opening in said body member.
