Tape strip pads and dispenser and method of dispensing individual tape strips
First Claim
1. A W-stacked pad of adhesive tape strips comprising a plurality of superimposed tape strips wherein:
- a. the tape strips include;
b. a substrate having first and second opposite major surfaces, first and second opposite longitudinal ends, a first longitudinal end portion adjacent the first end and a second longitudinal end portion adjacent the second end; and
c. a layer of an adhesive on the second major surface of the substrate;
d. sequential tape strips are longitudinally reversed so as to align the first end of each tape strip with the second end of an immediately overlaying and an immediately underlying tape strip;
e. the adhesive layer of each tape strip is releasably adhered to an adjacent tape strip;
f. the adhesive layer of each tape strip adheres the second end portion of each tape strip to the first end portion of an adjacent tape strip at a second adhesion level having an adhesive strength sufficient to prevent any appreciable longitudinal movement of the second end portion of an intermediate tape strip relative to the first end portion of an immediately underlying tape strip when an immediately overlying tape strip is dispensed from the pad at a high peel angle; and
g. the adhesive layer of each tape strip adheres the first end portion of each tape strip to the second end portion of an adjacent tape strip at a first adhesion level, with (i) the first adhesion level having a adhesive strength greater than about 1½
times the adhesive strength of the second adhesion level, and (ii) the first adhesion level having an adhesive strength effective for affording a complete release of the overlying tape strip from the intermediate tape strip after the second end portion of the intermediate tape strip is released from the first end portion of the immediately underlying tape strip and before the intermediate tape strip is completely peeled from the second end portion of the immediately underlying tape strip.

Abstract
A W-stacked pads of tape strips dispensable at a low peel angle, comprising a plurality of superimposed tape strips longitudinally reversed so as to align the first end of each tape strip with the second end of an immediately overlaying and an immediately underlying tape strip. The individual tape strips having first and second longitudinal end portions with differential release characteristics, with the second end portion of each tape strip adhered to the first end portion of an adjacent tape strip at an adhesion level having an adhesive strength sufficient to allow release of the second end portion of an intermediate tape strip relative to the first end portion of an immediately underlying tape strip when an immediately overlying tape strip is dispensed from the pad at a low peel angle, while preventing any appreciable longitudinal movement of the second end portion of an intermediate tape strip relative to the first end portion of an immediately underlying tape strip when an immediately overlying tape strip is dispensed from the pad at a high peel angle.

11. A dispenser for dispensing a W-stacked pad of adhesive tape strips comprising:
-
a. a housing defining a retention chamber configured and arranged to hold a W-stacked pad of adhesive tape strips, and having a top with an opening configured and arranged for accepting passage of an adhesively bonded combination of a first longitudinal end portion of an overlaying adhesive tape strip and a second longitudinal end portion of an immediately adjacent intermediate tape strip, as the overlaying adhesive tape strip is dispensed through the opening, from a W-stacked pad of adhesive tape strips within the retention chamber; and
b. a means for engaging the overlaying adhesive tape strip as the overlaying adhesive tape strip is dispensed through the opening so as to invariably provide a low peel angle between the overlaying adhesive tape strip and the immediately adjacent intermediate adhesive tape strip at the point of release of the second end portion of the intermediate adhesive tape strip from an adjacent underlying adhesive tape strip. - View Dependent Claims (13, 16, 17, 19, 20, 21, 28)

12. A dispenser for dispensing a W-stacked pad of adhesive tape strips comprising:
-
a. a housing defining a retention chamber configured and arranged to hold a W-stacked pad of adhesive tape strips and having a top with an opening configured and arranged for accepting simultaneous passage of a first longitudinal end portion of an overlaying adhesive tape strip and a second longitudinal end portion of an intermediate tape strip adhered to the first longitudinal end of the overlaying adhesive tape strip from a W-stacked pad of adhesive tape strips held within the retention chamber; and
b. a means for engaging the overlaying adhesive tape strip as the overlaying adhesive tape strip is dispensed through the opening so as to invariably limit the peel angle between the overlaying adhesive tape strip and the immediately adjacent intermediate adhesive tape strip to an angle of less than 45°
with a longitudinal length of at least 0.2 cm of the first longitudinal end portion of the overlaying adhesive tape strip still adhered to the second end portion of the intermediate adhesive tape strip. - View Dependent Claims (14, 15, 18, 22, 24, 25, 26, 27, 29)

30. A method of dispensing an overlying tape strip from a W-stacked pad of differential release tape strips at a restricted peel angle, wherein the pad has sequential tape strips longitudinally reversed so as to align a first longitudinal end of each tape strip with a second longitudinally end of an immediately overlaying and an immediately underlying tape strip and the pad includes at least (i) an overlying tape strip having a first longitudinal end and a second longitudinal end, (ii) an intermediate tape strip immediately underneath the overlying tape strip and having a first longitudinal end and a second longitudinal end, and (iii) an underlying tape strip immediately underneath the intermediate tape strip, sequentially comprising:
-
a. pulling the second longitudinal end of the overlying tape strip away from the pad so as to effect peeling of the overlying tape strip from the intermediate tape strip in a progressive fashion from the second longitudinal end of the overlying tape strip towards the first longitudinal end of the overlying tape strip;
b. contacting the overlying tape strip so as to restrict the peel angle between the overlying tape strip and the intermediate tape strip to an angle of less than 45°
prior to complete separation of the overlying tape strip from the intermediate tape strip and prior to release of a second longitudinal end section of the intermediate tape strip from the underlying tape strip, andc. continuing to pull the overlying tape strip away from the pad to sequentially effect (i) release of the second longitudinal end section of the intermediate tape strip from the underlying tape strip, and (ii) complete separation of the overlying tape strip from the intermediate tape strip. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
