Claims
- 1. 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.
- 2. 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.
- 3. 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.
- 4. 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 the same in width as a space on a same inner surface where said release agent is not provided, said strips of release agent on both label sheets being arranged in a positionally staggered manner; and
- said strips of adhesive are narrower than 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.
- 5. The linerless pressure-sensitive label of claim 4, 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.
- 6. The linerless pressure-sensitive label of claim 4, 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.
- 7. 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 space therebetween where no release agent is provided, said space where no release agent is provided being narrower than said strips of release agent; and
- said strips of adhesive are narrower than said strips of release agent, and are provided respectively on said inner surfaces of said top and bottom label sheets such that each strips of adhesive snugly fills in said space;
- whereby said strips of adhesive are arranged on said inner surfaces of both of said top and bottom label sheets with a non-adhesive narrow gap between one another.
- 8. The linerless pressure-sensitive label of claim 1, 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.
- 9. The linerless pressure-sensitive label of claim 1, wherein said strips of adhesive have a thickness which is at least two times greater than the thickness of said strips of release agent.
- 10. The linerless pressure-sensitive label of claim 1, wherein said non-adhesive narrow gap has a width which is substantially smaller than the respective widths of said strips of adhesive and said strips of release agent.
