Abstract
Abstract A planar index tab suitable for marking particular pages of a book or the like has one of its surfaces only locally coated with a pressure sensitive adhesive. The portion of the index tab coated with the adhesive is placed in adhesive contact with the page to be marked so that the portion of the index tab not coated with the adhesive projects beyond the margin of the page. Further, an index tab device for storing and dispensing index tabs having a backing sheet which has at least one surface with a low adhesive affinity to the pressure sensitive adhesive locally coating the index tabs. A plurality of index tabs are disposed in spaced apart array on the surface of the backing sheet having low adhesive affinity with the surface of the tabs locally coated with the adhesive in adhesive contact therewith.

Claim 1
Independent Claim
391 words
An index tab device for storing and dispensing at least one index tab comprising: a thin planar tab forming body having a first planar surface coated portion with a pressure sensitive adhesive on no more than one-half of said first surface thereby leaving a remainder of said first surface uncoated such that when said first planar surface is mounted contiguous to a backer sheet only said coated portion adheres to said backer sheet while said uncoated portion allows unrestrained removal of said tab from said backer sheet without affecting the adhesive property of said coated portion by grasping said tab by said uncoated surface area; an opposite planar surface suitable for printing conspicuous indexing information, whereby when said tab is removed from said backer sheet and applied along the edge of a multiple-part indexable item in a manner such that said no more than one half of said first surface coated with pressure sensitive adhesive is applied directly to a part of said multiple-part indexable item, said uncoated remainder of said first surface protruding from said multiple-part indexable item beyond the edge thereof, thereby exposing said opposite planar surface and appropriate indexing information printed thereon despite said multiple-part indexable item being closed or complied so as to conceal said no more than one-half of said first planar surface, thereby facilitating location of a part of said multiple-part indexable item according to correlation between said indexing information and the part attached thereto; and a flexible index tab backer sheet having at least one surface with a low adhesive affinity to said pressure sensitive adhesive and having said first planar surface of said at least one index tab applied thereto for dispensing said at least one tab wherein said at least one index tab is disposed on said at least one surface of said backer sheet having said low adhesive affinity with said no more than one-half of said first planar surface of each of said at least one tab forming body in contact with said one surface of said backer sheet having said low adhesive affinity, thus, maintaining said at least one index tab in position on said backer sheet while allowing any of said at least one index tab to be selectively and easily detached from said backer sheet without affecting the adhesive property of said at least one index tab.
Claim 2
Dependent Claim
391 words
An index tab device for storing and dispensing at least one index tab comprising: a thin planar tab forming body having a first planar surface coated portion with a pressure sensitive adhesive on no more than one-half of said first surface thereby leaving a remainder of said first surface uncoated such that when said first planar surface is mounted contiguous to a backer sheet only said coated portion adheres to said backer sheet while said uncoated portion allows unrestrained removal of said tab from said backer sheet without affecting the adhesive property of said coated portion by grasping said tab by said uncoated surface area; an opposite planar surface suitable for printing conspicuous indexing information, whereby when said tab is removed from said backer sheet and applied along the edge of a multiple-part indexable item in a manner such that said no more than one half of said first surface coated with pressure sensitive adhesive is applied directly to a part of said multiple-part indexable item, said uncoated remainder of said first surface protruding from said multiple-part indexable item beyond the edge thereof, thereby exposing said opposite planar surface and appropriate indexing information printed thereon despite said multiple-part indexable item being closed or complied so as to conceal said no more than one-half of said first planar surface, thereby facilitating location of a part of said multiple-part indexable item according to correlation between said indexing information and the part attached thereto; and a flexible index tab backer sheet having at least one surface with a low adhesive affinity to said pressure sensitive adhesive and having said first planar surface of said at least one index tab applied thereto for dispensing said at least one tab wherein said at least one index tab is disposed on said at least one surface of said backer sheet having said low adhesive affinity with said no more than one-half of said first planar surface of each of said at least one tab forming body in contact with said one surface of said backer sheet having said low adhesive affinity, thus, maintaining said at least one index tab in position on said backer sheet while allowing any of said at least one index tab to be selectively and easily detached from said backer sheet without affecting the adhesive property of said at least one index tab.
Claim 3
Dependent Claim
241 words
An index tab for use in indexing a multple-part indexable item comprising: a thin planar tab forming body having a first planar surface coated portion with a pressure sensitive adhesive on no more than one-half of said first surface thereby leaving a remainder of said first surface uncoated such that when said first planar surface is mounted contiguous to a backer sheet only said coated portion adheres to said backer sheet while said uncoated portion allows unrestrained removal of said tab from said backer sheet without affecting the adhesive property of said coated portion by grasping said tab by said uncoated surface area; and an opposite planar surface suitable for printing conspicuous indexing information, whereby when said tab is removed from said backer sheet and applied along the edge of a multiple-part indexable item in a manner such that said no more than one half of said first surface coated with pressure sensitive adhesive is applied directly to a part of said multiple part indexable item, said uncoated remainder of said first surface protruding from said multiple-part indexable item beyond the edge thereof, thereby exposing said opposite planar surface and appropriate indexing information printed thereon despite said multiple-part indexable item being closed or complied so as to conceal said no more than one-half of said first planar surface, thereby facilitating location of a part of said multiple-part indexable item according to correlation between said indexing information and the part attached thereto.
Claim 4
Dependent Claim
241 words
An index tab for use in indexing a multple-part indexable item comprising: a thin planar tab forming body having a first planar surface coated portion with a pressure sensitive adhesive on no more than one-half of said first surface thereby leaving a remainder of said first surface uncoated such that when said first planar surface is mounted contiguous to a backer sheet only said coated portion adheres to said backer sheet while said uncoated portion allows unrestrained removal of said tab from said backer sheet without affecting the adhesive property of said coated portion by grasping said tab by said uncoated surface area; and an opposite planar surface suitable for printing conspicuous indexing information, whereby when said tab is removed from said backer sheet and applied along the edge of a multiple-part indexable item in a manner such that said no more than one half of said first surface coated with pressure sensitive adhesive is applied directly to a part of said multiple part indexable item, said uncoated remainder of said first surface protruding from said multiple-part indexable item beyond the edge thereof, thereby exposing said opposite planar surface and appropriate indexing information printed thereon despite said multiple-part indexable item being closed or complied so as to conceal said no more than one-half of said first planar surface, thereby facilitating location of a part of said multiple-part indexable item according to correlation between said indexing information and the part attached thereto.
