Abstract
Abstract A dispenser for a roll of strip comprising an open top casing. A cover is pivotally mounted on the casing for closing the top thereof. Disposed within the casing is a roll of strip having transverse slits formed therein at predetermined distances along the strip. The free end of the strip to be removed from the roll of strip exits from an opening located between the casing and the cover. Extending from the casing are transversely spaced tracks that project outwardly and downwardly from the casing, and over which advances the free end of the roll of strip. Extending from the cover are outwardly and downwardly transversely spaced guides, which overlie, respectively, the transverse tracks to form passages therebetween. The free end of the strip travels through these passages. The tracks and guides are correspondingly curved to bow the free end of the roll of strip at the transverse slit advancing through the passages to open the slit. A spring mounted on the casing applies a force to retard the egress of the strip of the roll of the tape. An operator grips the free end of the roll of strip disposed between the transversely spaced tracks and guides and applies a downward force to the free end of the roll of strip. The free end of the roll of strip is torn from the roll of strip at the transverse slit exiting from the passages by virtue of the force applied to retard the egress of the roll of strip of the roll of strip, the force applied to the free end of the roll of strip by the operator, and the frangibility of the free end of the roll of strip at the opened slit.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
232 words
A dispenser for tearing strips from a roll of flexible strip with slits at predetermined locations therealong comprising: (a) a container for housing a roll of strip, and container being formed with an exit opening through which the free end of the roll of strip advances from the container; (b) means in said container engaging strip of said roll of strip for applying a force to retard the the egress of the strip from said container; (c) transversely spaced curved twisted tracks projecting from said container over which the free end of the roll of strip advances; and (d) transversely spaced curved twisted guides projecting from said container in overlying relation to said tracks respectively to form transversely spaced curved twisted passages therebetween through which the free end of said roll of strip advances, said curved twisted tracks and said curved twisted guides being arranged to open a slit of said roll of strip while said slit is advancing through said passages by bowing the free end of the strip advancing therebetween at the slit, whereby the free end of the roll of strip is torn from the roll of strip at the opened slit through the application of force applied to the free end thereof, the application of the retading force applied by said means and the frangibility of the free end of the roll of strip at the opened slit.
Claim 2
Dependent Claim
232 words
A dispenser for tearing strips from a roll of flexible strip with slits at predetermined locations therealong comprising: (a) a container for housing a roll of strip, and container being formed with an exit opening through which the free end of the roll of strip advances from the container; (b) means in said container engaging strip of said roll of strip for applying a force to retard the the egress of the strip from said container; (c) transversely spaced curved twisted tracks projecting from said container over which the free end of the roll of strip advances; and (d) transversely spaced curved twisted guides projecting from said container in overlying relation to said tracks respectively to form transversely spaced curved twisted passages therebetween through which the free end of said roll of strip advances, said curved twisted tracks and said curved twisted guides being arranged to open a slit of said roll of strip while said slit is advancing through said passages by bowing the free end of the strip advancing therebetween at the slit, whereby the free end of the roll of strip is torn from the roll of strip at the opened slit through the application of force applied to the free end thereof, the application of the retading force applied by said means and the frangibility of the free end of the roll of strip at the opened slit.
Claim 3
Dependent Claim
22 words
A dispenser as claimed in claim 1 wherein said transversely curved tracks and said transversely curved guides project in a downward direction.
Claim 4
Dependent Claim
104 words
A dispenser as claimed in claim 2 wherein said container comprises a casing with an open top for disposing the roll of strip therein, and a cover pivotally connected to said casing for closing the top thereof and pivotal to a retracted position for the insertion and removal of the roll of strip in said casing, said transversely spaced tracks extending from said casing to project therefrom, said transversely spaced guides extending from said cover to project therefrom and being arranged to overlie said transversely spaced tracks to form said transversely spaced passages through which the free end of the roll of strip advances.
Claim 5
Dependent Claim
35 words
A dispenser as claimed in claim 3 and comprising interlocking means interlocking said casing and said cover adjacent to said transversely spaced tracks and said transversely spaced guides for interlocking said cover and said casing.
