Abstract
Abstract A carton for dispensing articles such as paper cups is formed from a single blank of material. The carton has four wall panels arranged to form a tube. One or more peripheral pleats are formed in the panels near one end of the carton so as to create resilient tabs which lay out away from the carton wall panels. These tabs resiliently engage the lowermost article in a stack of nested articles within the container so that the articles can be pulled one-by-one from the end of the carton.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
A carton comprising A. a tube of flexible material, B. a pair of relatively closely spaced peripheral score lines extending around the tube at selected locations along its length, C. a plurality of cutouts, 1. extending between the score lines, and 2. distributed around the periphery of the tube so that the tube can be collapsed lengthwise at the score lines to form two or more resilient tabs projecting inwardly toward the centerline of the tube, D. at least one additional pair of score lines spaced from the first pair, and E. a similar set of cutouts associated with the additional score line pair for forming an additional set of resilient internal tabs spaced axially along the tube from the first set, the score lines in each pair being formed so that when the tube is collapsed lengthwise, all the tabs point toward the same end of the tube.
Claim 2
Dependent Claim
149 words
A carton comprising A. a tube of flexible material, B. a pair of relatively closely spaced peripheral score lines extending around the tube at selected locations along its length, C. a plurality of cutouts, 1. extending between the score lines, and 2. distributed around the periphery of the tube so that the tube can be collapsed lengthwise at the score lines to form two or more resilient tabs projecting inwardly toward the centerline of the tube, D. at least one additional pair of score lines spaced from the first pair, and E. a similar set of cutouts associated with the additional score line pair for forming an additional set of resilient internal tabs spaced axially along the tube from the first set, the score lines in each pair being formed so that when the tube is collapsed lengthwise, all the tabs point toward the same end of the tube.
Claim 3
Dependent Claim
84 words
The carton defined in claim 1 wherein all of the tabs are located near said one end of the tube so that when a stack of nested articles is positioned in the tube with the small end of the lowermost article protruding from said one end of the tube, the tabs resiliently engage the lowermost article so as to retain the stack within the tube and permit articles to be pulled from the stack one by one from said one end of the tube.
Claim 4
Dependent Claim
107 words
distributed around the periphery of the tube so that the tube can be collapsed lengthwise at the score lines to form two or more resilient tabs projecting inwardly toward the centerline of the tube, D. at least one additional pair of score lines spaced from the first pair, and E. a similar set of cutouts associated with the additional score line pair for forming an additional set of resilient internal tabs spaced axially along the tube from the first set, the score lines in each pair being formed so that when the tube is collapsed lengthwise, all the tabs point toward the same end of the tube.
Claim 5
Dependent Claim
107 words
distributed around the periphery of the tube so that the tube can be collapsed lengthwise at the score lines to form two or more resilient tabs projecting inwardly toward the centerline of the tube, D. at least one additional pair of score lines spaced from the first pair, and E. a similar set of cutouts associated with the additional score line pair for forming an additional set of resilient internal tabs spaced axially along the tube from the first set, the score lines in each pair being formed so that when the tube is collapsed lengthwise, all the tabs point toward the same end of the tube.
Claim 6
Dependent Claim
37 words
The carton defined in claim 2 and further including A. means for closing said one end of the tube, B. means for removing the closure means, and C. means for closing the other end of the tube.
Claim 7
Dependent Claim
30 words
The carton defined in claim 3 wherein the removing means is comprised of a tear strip located between said one end of the tube and the nearest set of tabs.
Claim 8
Dependent Claim
31 words
The carton defined in claim 1 and further including a tear strip extending around the tube periphery adjacent the bottom end closure means to facilitate removal of the bottom closure means.
