Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 344 words
A refastenable tab of Y-configuration for diapers and the like formed of diaper tab stock comprising a web construction made up of initially flat but flexible substrate material and suitable to be formed in long passes along the machine direction of a coating and laminating line and to be rolled up for storage and shipment, and unrolled for use by diaper manufacturers, and fabricatable for storage and shipment completely by web coating and web-to-web laminating operations and without the necessity for folding or machine direction slitting operations, and suitable for high speed dispensing or automatic equipment, said tab including a first substrate extending, transversely to machine direction, along first and second length portions and bearing first substrate adhesive on its underside at both said first and second length portions, a second substrate extending along said first and second length portions and bearing second substrate adhesive on its underside at both said first and second length portions, release means for said first substrate adhesive located on said second substrate and below the first substrate adhesive at said second length portion, said first length portion being substantially free of said release means whereby said first substrate remains permanently associated with said second substrate throughout said first length portion up unto the border thereof that is adjacent said second length portion, said tab having two lateral sides formed by spaced transverse cuts across the machine direction of said tab stock, said tab also having an intermediate cut within the tab body, said intermediate cut extending generally intermediate said two lateral sides, and generally parallel thereto, said intermediate cut extending at least through said second length portion of said first substrate to define two side-by-side half-tab parts of said second length portions of said first substrate, each of a width to grip independently in a Y-configuration grip and each having its own part of said release means with said intermediate cut dividing said release means from itself to enable independent sequential deployment of said half-tab parts to sequentially form a first Y-configuration joint and a second Y-configuration joint.
Claim 2
Dependent Claim 344 words
A refastenable tab of Y-configuration for diapers and the like formed of diaper tab stock comprising a web construction made up of initially flat but flexible substrate material and suitable to be formed in long passes along the machine direction of a coating and laminating line and to be rolled up for storage and shipment, and unrolled for use by diaper manufacturers, and fabricatable for storage and shipment completely by web coating and web-to-web laminating operations and without the necessity for folding or machine direction slitting operations, and suitable for high speed dispensing or automatic equipment, said tab including a first substrate extending, transversely to machine direction, along first and second length portions and bearing first substrate adhesive on its underside at both said first and second length portions, a second substrate extending along said first and second length portions and bearing second substrate adhesive on its underside at both said first and second length portions, release means for said first substrate adhesive located on said second substrate and below the first substrate adhesive at said second length portion, said first length portion being substantially free of said release means whereby said first substrate remains permanently associated with said second substrate throughout said first length portion up unto the border thereof that is adjacent said second length portion, said tab having two lateral sides formed by spaced transverse cuts across the machine direction of said tab stock, said tab also having an intermediate cut within the tab body, said intermediate cut extending generally intermediate said two lateral sides, and generally parallel thereto, said intermediate cut extending at least through said second length portion of said first substrate to define two side-by-side half-tab parts of said second length portions of said first substrate, each of a width to grip independently in a Y-configuration grip and each having its own part of said release means with said intermediate cut dividing said release means from itself to enable independent sequential deployment of said half-tab parts to sequentially form a first Y-configuration joint and a second Y-configuration joint.
Claim 3
Dependent Claim 335 words
A diaper having a diaper tab as defined in claim 1 applied to a first part of the diaper, the tab being applied to one edge of the diaper with the first length portions of the second substrate adhesive, second substrate, first substrate adhesive, and first substrate respectively layered on one side of said one diaper edge and with the second length portions of the second substrate adhesive and second substrate, the release means, the second length portions of the first substrate adhesive and first substrate respectively layered on the opposite side of said one diaper edge and with the borders of said first and second length portions located outboard ot such diaper edge, whereby the tab, mounted on said one edge of the diaper, may be manipulated by a person to fasten, unfasten, and refasten the diaper by (1) peeling back one half-tab part of the second length portion of the first substrate, together with the corresponding part of the second length portion of the first substrate adhesive, from the release means to deploy the same and applying the same to another part of the diaper to thereby fasten the diaper with the first and second substrates remaining joined on said one side of said diaper edge and up unto said border to establish a first Y-configuration joint for said one half-tab while allowing the remaining undeployed half-tab, including portions thereof adjacent said diaper edge, to accommodate the formation of said first Y-configuration joint and remain in suitable condition for subsequent deployment to establish a second Y-configuration joint, (2) then removing said one half-tab part from said other part of the diaper to thereby unfasten the diaper, and (3) then peeling back the other half-tab part of the second length portion of the first substrate, together with the corresponding part of the second length portion of the first substrate adhesive, from the release means to deploy the same and applying the same to said another part of the diaper to thereby refasten the diaper.
