Abstract
Abstract A packaging tape made from a flexible member with a top surface and a bottom surface and a tape body therebetween. A central tear-away portion is formed by two parallel lines of perforations extending for the length of the flexible member. Finger openings located along each of the lines of perforations at spaced intervals expose the central tear-away portion to facilitate severing the flexible member longitudinally.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
A packaging tape, comprising: a flexible member having a length greater than its width and being adapted to be wound on a roll, the flexible member having a top surface and a bottom surface which define a tape body therebetween, at least a portion of the bottom surface of the flexible member having an adhesive applied thereto; a central, tear-away portion formed by two parallel lines of perforations extending for substantially the entire length of the flexible member; and the tape body being provided with finger openings located along each of the lines of perforations at spaced intervals which expose the central, tear-away portion to facilitate severing the flexible member longitudinally.
Claim 2
Dependent Claim
111 words
A packaging tape, comprising: a flexible member having a length greater than its width and being adapted to be wound on a roll, the flexible member having a top surface and a bottom surface which define a tape body therebetween, at least a portion of the bottom surface of the flexible member having an adhesive applied thereto; a central, tear-away portion formed by two parallel lines of perforations extending for substantially the entire length of the flexible member; and the tape body being provided with finger openings located along each of the lines of perforations at spaced intervals which expose the central, tear-away portion to facilitate severing the flexible member longitudinally.
Claim 3
Dependent Claim
170 words
A packaging tape, comprising: a flexible member having a length greater than its width and being adapted to be wound on a roll, the flexible member having a top surface and a bottom surface which define a tape body therebetween, at least a portion of the bottom surface of the flexible member having an adhesive applied thereto; a central, tear-away portion formed by two parallel lines of perforations extending for substantially the entire length of the flexible member, the perforations being formed to pass completely through the tape body from the top surface to the bottom surface thereof; and the tape body being provided with spaced pairs of finger openings passing through the tape body from the top surface to the bottom surface thereof, the spaced pairs of finger openings being located within and extending longitudinally along each of the lines of perforations at spaced intervals, to thereby divide the lines of perforations into line segments and to expose the central, tear-away portion to facilitate severing the flexible member longitudinally.
Claim 4
Dependent Claim
170 words
A packaging tape, comprising: a flexible member having a length greater than its width and being adapted to be wound on a roll, the flexible member having a top surface and a bottom surface which define a tape body therebetween, at least a portion of the bottom surface of the flexible member having an adhesive applied thereto; a central, tear-away portion formed by two parallel lines of perforations extending for substantially the entire length of the flexible member, the perforations being formed to pass completely through the tape body from the top surface to the bottom surface thereof; and the tape body being provided with spaced pairs of finger openings passing through the tape body from the top surface to the bottom surface thereof, the spaced pairs of finger openings being located within and extending longitudinally along each of the lines of perforations at spaced intervals, to thereby divide the lines of perforations into line segments and to expose the central, tear-away portion to facilitate severing the flexible member longitudinally.
Claim 5
Dependent Claim
25 words
The packaging tape of claim 2, wherein the spaced pairs of finger openings divide the lines of perforations into line segments of approximately equal length.
Claim 6
Dependent Claim
54 words
The packaging tape of claim 2, wherein the central tear-away portion of the tape body formed by the parallel lines of perforations is of generally rectangular planar area and separates an upper and lower body portion of generally planar rectangular area and of greater relative width than the width of the central tear-away portion.
Claim 7
Dependent Claim
40 words
The packaging tape of claim 4, wherein an adhesive is applied to the upper and lower planar rectangular areas of the bottom surface of the flexible member and wherein the central tear-away portion of the bottom surface is adhesive free.
