Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
125 words
A dispenser for a coreless material wound into a hollow, cylindrical, self-supporting roll contained therein, wherein the dispenser comprises a wall portion adjacent to the circumference of the roll and two ends adjacent to the end faces of said roll, said wall portion being provided with at least one first elongated aperture means through which the material, unwindable from the outside of said cylindrical roll, can be drawn from said dispenser, and wherein at least one of the two dispenser ends adjacent to the end faces of said roll is provided with second aperture means through a central zone of which passes the roll axis, through which second aperture means the material, unwindable from the inside of said roll, can be drawn from said dispenser.
Claim 2
Dependent Claim
125 words
A dispenser for a coreless material wound into a hollow, cylindrical, self-supporting roll contained therein, wherein the dispenser comprises a wall portion adjacent to the circumference of the roll and two ends adjacent to the end faces of said roll, said wall portion being provided with at least one first elongated aperture means through which the material, unwindable from the outside of said cylindrical roll, can be drawn from said dispenser, and wherein at least one of the two dispenser ends adjacent to the end faces of said roll is provided with second aperture means through a central zone of which passes the roll axis, through which second aperture means the material, unwindable from the inside of said roll, can be drawn from said dispenser.
Claim 3
Dependent Claim
34 words
The dispenser as claimed in claim 1, wherein said at least one first elongated aperture means and said second aperture means are formed by removing perforated portions to provide a slot and hole, respectively.
Claim 4

The dispenser as claimed in claim 1, wherein said first aperture means consists of a slot extending parallel to the roll axis, and wherein said second aperture means consists of a hole.
Claim 5
Dependent Claim
74 words
The dispenser as claimed in claim 2 or 3, wherein said at least one of two dispenser ends is provided with perforations for tearing-out a second hole, larger than the first hole, so that after unwinding and drawing off part of the material from the inside of said roll, tearing-out of said second hole will facilitate the drawing from said dispenser of the rest of the material, unwindable from the inside of said roll.
Claim 6
Dependent Claim
62 words
The dispenser as claimed in claim 3, wherein a part of said dispenser wall is angularly bent so as to project over said slot, said part being provided with a surface facing said slot, which surface is adapted to offer said material, when pulled across said surface, a frictional resistance, whereby a sudden pull will cause said material to be torn off.
Claim 7
Dependent Claim
59 words
The dispenser as claimed in claims 1 and 3, wherein said dispenser consists of a bag made of plastic foil provided with said aperture means, and wherein said bag contains an insert holding said roll, which insert is made of a rigid material and imparts to said plastic bag a substantially permanent shape facilitating its use as a dispenser.
Claim 8
Dependent Claim
16 words
The dispenser as claimed in claim 1, wherein a carrying strap is attached to said dispenser.
Claim 9
Dependent Claim
15 words
