Abstract
Abstract An improved linerless pressure-sensitive label construction wherein label sheets carrying pertinent messages are pasted together with pressure-sensitive adhesive without using a release liner, and by separating the pasted-together label sheets, each separated section can be used as a label. Strips of release agent are provided at a given interval on the top and the bottom label sheets on their respective facing faces, the strips being arranged in a positionally staggered manner, so that the strips of release agent on one of the label sheets will come in contact with the strips of adhesive on the other. The strips of adhesive on either one of the label sheets are separated from one another by a narrow gap, so that the strips of adhesive which hold the top and the bottom label sheets together are separated from each other at the narrow gap and also from the strips of release agent on the other label sheet when the top and the bottom label sheets are peeled off from each other, whereby the label sheets can be easily separated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
273 words
A linerless pressure-sensitive label comprising: top and bottom label sheets having mutually facing inner surfaces that are adhered together via an adhesive and a release agent; strips of release agent provided on an inner surface of said top label sheet and on a mutually facing inner surface of said bottom label sheet, said strips of release agent being provided on said inner surfaces of each of said label sheets with a given spacing between adjacent strips of release agent, said strips of release agent on said top label sheet being positionally staggered from said strips of release agent on said bottom label sheet; strips of adhesive arranged between said strips of release agent on said top label sheet and said inner surface of said bottom label sheet, and arranged between said strips of release agent on said bottom label sheet and said inner surface of said top label sheet; said strips of release agent and said strips of adhesive having respective widths in a direction of a plane of said inner surfaces of said top and bottom label sheets, and having respective thicknesses in a direction perpendicular to said inner surfaces of said top and bottom label sheets; said strips of adhesive on said top label sheet all being separated in a width direction of said strips from strips of adhesive on said bottom label sheet which are adjacent to said strips of adhesive on said top label sheet by means of a non-adhesive narrow gap between said adjacent strips of adhesive; and said strips of adhesive having a thickness which is substantially greater than the thickness of said strips of release agent.
Claim 2
Dependent Claim
273 words
A linerless pressure-sensitive label comprising: top and bottom label sheets having mutually facing inner surfaces that are adhered together via an adhesive and a release agent; strips of release agent provided on an inner surface of said top label sheet and on a mutually facing inner surface of said bottom label sheet, said strips of release agent being provided on said inner surfaces of each of said label sheets with a given spacing between adjacent strips of release agent, said strips of release agent on said top label sheet being positionally staggered from said strips of release agent on said bottom label sheet; strips of adhesive arranged between said strips of release agent on said top label sheet and said inner surface of said bottom label sheet, and arranged between said strips of release agent on said bottom label sheet and said inner surface of said top label sheet; said strips of release agent and said strips of adhesive having respective widths in a direction of a plane of said inner surfaces of said top and bottom label sheets, and having respective thicknesses in a direction perpendicular to said inner surfaces of said top and bottom label sheets; said strips of adhesive on said top label sheet all being separated in a width direction of said strips from strips of adhesive on said bottom label sheet which are adjacent to said strips of adhesive on said top label sheet by means of a non-adhesive narrow gap between said adjacent strips of adhesive; and said strips of adhesive having a thickness which is substantially greater than the thickness of said strips of release agent.
Claim 3
Dependent Claim
124 words
The linerless pressure-sensitive label of claim 1, wherein: said strips of release agent provided on said inner surface of each of said top and bottom label sheets are arranged with a spacing therebetween which is narrower than a width of a space where the release agent is not provided, and are arranged in a positionally staggered manner; and said strips of adhesive have substantially the same width as said strips of release agent, and are provided respectively on said inner surfaces of said top and bottom label sheets where said strips of release agent are provided; whereby said strips of adhesive are arranged on said inner surface of each of said top and bottom label sheets with a non-adhesive narrow gap between one another.
Claim 4
Dependent Claim
117 words
The linerless pressure-sensitive label of claim 2, wherein: said strips of adhesive provided on said inner surface of each of said top and bottom label sheets with a non-adhesive narrow gap between adjacent strips of adhesive, are applied by supplying adhesive onto said strips of release agent on one of said top and bottom label sheets and are also applied in said space between said strips of release agent on said inner surface of said one of said label top and bottom sheets, said adhesive being supplied through a nozzle formed at a bottom of a pair of shim holders via plural teeth projecting at a regular interval from a shim plate interposed between said shim holders.
Claim 5
Dependent Claim
