Abstract: A novel tape dispenser especially useful in dispensing pressure-sensitive adhesive tape of the type having a plurality of longitudinally spaced zones which appreciably increase the force required to strip the tape from the roll compared to areas intermediate these zones. Features of the invention include: an adjustable blade on the dispenser frame, in one embodiment, which may set at desired distances from the roll to accommodate various dimensional characteristics of different tapes; a limiting structure for preventing the roll of tape from being pulled bodily out of the dispenser; and a unique arrangement for mounting and maintaining the tape such that the line of departure of tape from the roll is maintained in fixed position on the dispenser frame.In one embodiment the support means for the tape roll defines a path inclining downwardly toward a lip on the frame across which tape is drawn as it is stripped from the roll.

Abstract: A tape product for use in attaching shipping documents (such as packing slips, sales slips, invoices, letters) or the like to the outside of various containers with the tape being transparent and including a sticky adhesive material on the back side thereof with one or more separate coated layers also on the back side of the tape, said coated layers comprising in one embodiment a first layer of backward printed letters which are readable when the tape is in position on a container and a second layer comprised of a contrasting background color which facilitates the reading of the letters when the tape is in position on the container, in another embodiment a single layer of transparent coating material, and in other embodiments opaque and transparent layers used in various combinations with one another and in differing areas and number of layers, such layers rendering a portion of the adhesive material nonsticky so that documents may be retained without tearing or sticking to the tape product; and, the method o
