Abstract
Abstract A flag of unitary construction formed from a sheet of flexible, semi-rigid material having a central adhesive section on one side, flanked by two symmetrical adhesive free tabs which are printed so as to facilitate indexing or signaling of flagged material, may be reversibly attached to host material book, file card, file folder or the like proximate a free edge with one adhesive free tab protruding from the free edge host and one tab overlying a portion of the flagged host. The flag may be removed from the flagged host by grasping the adhesive free overlaying tab and peeling the flag outward relative to the free edge of the host without damage to the host, or the flag may be used to flag a section of text not proximate an edge of a host by pressing down the transparent adhesive bearing central section directly over or adjacent to the portion of text to be flagged.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
74 words
A flag comprising a unitary sheet of thin semi-rigid flexible material having a central adhesive-bearing section on one side and two enlarged adhesive-free tabs flanking said adhesive-bearing section, said flag being adapted to be releasably attached to a host along a proximate free edge of said host such that one of said flag adhesive-free areas protrudes from the edge of said host, while the other flag adhesive-free area overlays a portion of said host.
Claim 2
Dependent Claim
74 words
A flag comprising a unitary sheet of thin semi-rigid flexible material having a central adhesive-bearing section on one side and two enlarged adhesive-free tabs flanking said adhesive-bearing section, said flag being adapted to be releasably attached to a host along a proximate free edge of said host such that one of said flag adhesive-free areas protrudes from the edge of said host, while the other flag adhesive-free area overlays a portion of said host.
Claim 3
Dependent Claim
37 words
A flag as defined in claim 1, wherein said flag is adapted to be affixed to said host in either of two directions such that either of said adhesive-free areas may protrude from or overlay said host.
Claim 4
Dependent Claim
19 words
A flag as defined in claim 2, wherein adhesive-free tabs are substantially symmetrical about a central axis of adhesion.
Claim 5
Dependent Claim
22 words
A flag as defined in claim 3, wherein said adhesive-free tabs are symmetrically tapered outwardly from either side of said adhesive-bearing section.
Claim 6
Dependent Claim
45 words
A flag as defined in claim 3, wherein said substantially symmetrical adhesive-free tabs are substantially symmetrically provided with symbolic sequencing such that the indexing and organization of flagged material may be facilitated regardless of which of said tabs protrudes from the edge of said host.
Claim 7
Dependent Claim
25 words
A flag as defined in claim 5, wherein said substantially symmetrical adhesive-free tabs have color coding which is substantially the same on each of them.
Claim 8
Dependent Claim
24 words
A flag as defined in claim 4, wherein said flag is generally square, with the adhesive-bearing section thereof being disposed diagonally within said square.
Claim 9
Dependent Claim
44 words
A flag as defined in claim 1, wherein said protruding adhesive-free tab is tapered so as to be able to be cammed away from a striking object, thereby minimizing the transmission of a striking force which might otherwise be potentially damaging to said host.
Claim 10
Dependent Claim
29 words
A flag as defined in claim 8, wherein the taper of said protruding adhesive-free tab culminates in a rounded vertex which enhances the camming action of said protruding tab.
Claim 11
Dependent Claim
23 words
A flag as defined in claim 8, wherein the taper of said protruding adhesive-free tab enhances the flexibility of said protruding adhesive-free tab.
Claim 12
Dependent Claim
39 words
A flag as defined in claim 1, wherein said protruding adhesive free tab is sufficiently flexible to deflect under a striking force, thereby minimizing the transmission of a striking force which might otherwise be potentially damaging to said host.
Claim 13
Dependent Claim
51 words
A flag as defined in claim 1, wherein the lateral extent of said adhesive-free overlaying tab is sufficient to be grasped and peeled back outwardly relative to the free edge of said host, thereby facilitating removal of said flag from said indexed sheet with little or no damage to said host.
Claim 14
Dependent Claim
47 words
A flag as defined in claim 12, wherein said adhesive-free overlaying tab is tapered in order to facilitate grasping said overlaying tab for removal of said flag from said host, and said taper of said overlaying adhesive-free tab serves to enhance the flexibility of said overlaying tab.
Claim 15
Dependent Claim
46 words
A flag as defined in claim 1, wherein the longitudinal extremes of said adhesive-bearing section are rounded such that said longitudinal extremes of said adhesive-bearing section will smoothly release from said host during detachment of said flag, thereby causing little or no damage to said host.
Claim 16
Dependent Claim
27 words
A flag as defined in claim 1, wherein said protruding adhesive-free tab has symbolic sequencing thereon in order to facilitate the indexing and organization of flagged material.
Claim 17
Dependent Claim
16 words
A flag as defined in claim 1, wherein said protruding adhesive-free tab has color coding thereon.
Claim 18
Dependent Claim
19 words
A flag as defined in claim 1, wherein said protruding adhesive-free area is provided with enhanced light reflecting capability.
Claim 19
Dependent Claim
20 words
A flag as defined in claim 17, wherein said light-reflecting capability is provided by means of metallization of said flag.
Claim 20
Dependent Claim
46 words
A flag as defined in claim 1, wherein said central adhesive-bearing section is substantially transparent, whereby a portion of text printed internally on the host material may be flagged by adhesively attaching said central section of said flag directly over or adjacent to such text portion.
Claim 21
Dependent Claim
27 words
A locator flag as defined in claim 1, wherein said protruding area is coded with routing and sorting instructions which may be mechanically interpreted and carried out.
Claim 22
Dependent Claim
20 words
A locator flag as defined in claim 20, wherein the coding of said routing and sorting instructions comprises electro-magnetic coding.
Claim 23
Dependent Claim
20 words
A locator flag as defined in claim 20, wherein the coding of said routing and sorting instructions comprises light-reflective coding.
Claim 24
Dependent Claim
24 words
A located flag as defined in claim 22, wherein said light-reflective coding is enhanced by forming said locator flag of highly light reflective material.
