Abstract
Abstract A system for aligning portions of a carrier blank during the folding of a carrier blank into a folded carrier wherein an abutment tab having an abutment edge is provided in one portion of the carrier blank with the one portion having a first linear edge and wherein an abutment edge is provided in a second portion of the carrier blank with the second portion having a second linear edge so that when the first and second portions of the carrier blank are moved into adjacent relationship, the abutment edges move into a contacting relationship to guide the first and second linear edges into a superposed and aligned relationship.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
253 words
A carrier blank comprising: a relatively flat carrier blank having in a partially folded condition at least a first portion and a second portion joined together by a fold line with said first and second portions having oppositely facing generally planar surfaces when folded around said fold line so that said first and second portions are in a superposed relationship; means for forming an abutment tab in said first portion of said carrier blank, said means comprising at least one linear cut line and a fold line; a portion of said abutment tab projecting out of said generally planar surface of said first portion to form a linear abutment edge from said one linear cut line; means for forming a linear abutment edge in said second portion of said carrier blank said linear abutment edge in said second portion being parallel to said at least one linear cut line; and said linear abutment edge on said abutment tab and said linear abutment edge in said second portion being located so that as said first portion and said second portion are being folded together, said abutment edges will move into contacting relationship so as to guide the movement of said first and second portions so that when said carrier blank is completely folded with said generally planar surfaces in contacting relationship, at least portions of said abutment edges are in contact with each other and said linear abutment edge on said abutment tab is parallel with said linear abutment edge in said second portion.
Claim 2
Dependent Claim
253 words
A carrier blank comprising: a relatively flat carrier blank having in a partially folded condition at least a first portion and a second portion joined together by a fold line with said first and second portions having oppositely facing generally planar surfaces when folded around said fold line so that said first and second portions are in a superposed relationship; means for forming an abutment tab in said first portion of said carrier blank, said means comprising at least one linear cut line and a fold line; a portion of said abutment tab projecting out of said generally planar surface of said first portion to form a linear abutment edge from said one linear cut line; means for forming a linear abutment edge in said second portion of said carrier blank said linear abutment edge in said second portion being parallel to said at least one linear cut line; and said linear abutment edge on said abutment tab and said linear abutment edge in said second portion being located so that as said first portion and said second portion are being folded together, said abutment edges will move into contacting relationship so as to guide the movement of said first and second portions so that when said carrier blank is completely folded with said generally planar surfaces in contacting relationship, at least portions of said abutment edges are in contact with each other and said linear abutment edge on said abutment tab is parallel with said linear abutment edge in said second portion.
Claim 3
Dependent Claim
71 words
A carrier blank as in claim 1 and further comprising: a first linear edge in said first portion; a second linear edge in said second portion; and said first and second linear edges being located relative to said abutment edges so that said first and second linear edges will be guided into a superposed and aligned relationship by the contact between said abutment edges during the folding of said carrier blank.
Claim 4
Dependent Claim
39 words
A carrier blank as in claim 2 wherein said means forming an abutment tab comprises: a pair of intersecting linear cut lines; and a fold line extending between the ends of said linear cut lines remote from their intersection.
Claim 5
Dependent Claim
18 words
A carrier blank as in claim 3 wherein: said pair of intersecting linear cut lines have different lengths.
Claim 6
Dependent Claim
71 words
A carrier blank as in claim 3 and further comprising: a third linear edge in said first portion; a fourth linear edge in said second portion; and said third and fourth linear edges being located relative to said abutment edges so that said third and fourth linear edges will be guided into a superposed and aligned relationship by the contact between said abutment edges during said folding of said carrier blank.
