Abstract
Abstract A carton with improved hand holes for facilitating lifting the carton, the hand holes being unusually resistant to tearing when the carton is lifted. In one aspect of the invention, the improved hand holes take the form of inverted V cutouts located on opposed sidewall panels of the carton. In another aspect of the invention, the improved hand holes take the form of at least one inclined, elongated, slot-shaped cutout located on each of two opposed sidewall panels of the carton. In both aspects of the invention, a longitudinal axis of the inclined cutout will intersect the plane of a bottom closure means for the carton at an acute angle measured between the extended longitudinal axis and the plane. Also in both aspects of the invention, the improvement in tear resistance results from distributing the lifting force as both a vertical and a horizontal load in the carton sidewall and from increasing the area of the carton over which the load or lifting force is distributed. Furthermore, in both aspects of the invention, the hand holes may be provided with flaps to keep them closed when not in use.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
In a carton wherein two pairs of opposed sidewall panels are hingedly connected along substantially vertical foldable connections to form a tubular configuration, and wherein said tubular configuration is provided with a substantially horizontally disposed bottom closure means, the improvement which comprises: elongated inclined hand hole means in each of a pair of opposed sidewall panels, said inclined hand hole means being located intermediate the height and width of said sidewall panels, said inclined hand hole means comprising a pair of substantially inverted V shaped hand hole cutouts, one of said inverted V hand holes being located on each of said opposed sidewall panels, the extension of the longitudinal axis of each leg of said inverted V intersecting the plane of said bottom closure means at an acute angle.
Claim 2
Dependent Claim
129 words
In a carton wherein two pairs of opposed sidewall panels are hingedly connected along substantially vertical foldable connections to form a tubular configuration, and wherein said tubular configuration is provided with a substantially horizontally disposed bottom closure means, the improvement which comprises: elongated inclined hand hole means in each of a pair of opposed sidewall panels, said inclined hand hole means being located intermediate the height and width of said sidewall panels, said inclined hand hole means comprising a pair of substantially inverted V shaped hand hole cutouts, one of said inverted V hand holes being located on each of said opposed sidewall panels, the extension of the longitudinal axis of each leg of said inverted V intersecting the plane of said bottom closure means at an acute angle.
Claim 3
Dependent Claim
77 words
The improvement of claim 1, wherein said hand hole means further includes: two pairs of hand hole closing flaps, one pair for each of said pair of inverted V hand holes, each of said pair of closing flaps being of the same shape as said inverted V hand holes and hinged to said sidewall panel along score lines coincident with the edge of intersecting legs of said inverted V hand holes away from said bottom closure means.
Claim 4
Dependent Claim
14 words

Claim 6
Dependent Claim
199 words
In a carton wherein two pairs of opposed sidewall panels are hingedly connected along substantially vertical foldable connections to form a tubular configuration, and wherein said tubular configuration is provided with a substantially horizontally disposed bottom closure means, the improvement which comprises: elongated inclined hand hole means in each of a pair of opposed sidewall panels, said inclined hand hole means being located intermediate the height and width of said sidewall panels, said inclined hand hole means comprising two pairs of substantially elongated slot-shaped hand hole cutouts, each elongated slot hand hole being defined by two substantially parallel, coextensive cut lines connected at their respective ends by continuous cut lines, one of said pair of slot-shaped hand holes being located on each of said opposed sidewall panels, each of said pairs of slot-shaped hand holes being placed on said opposed sidewall panels such that one of each pair is adjacent one of the foldable connections of said sidewall panel and the other of said pair is adjacent the other foldable connection of said sidewall panel, the extended longitudinal axes of all of said elongated slot-shaped hand holes intersecting the plane of said bottom closure means at an acute angle.
Claim 7
Dependent Claim
199 words
In a carton wherein two pairs of opposed sidewall panels are hingedly connected along substantially vertical foldable connections to form a tubular configuration, and wherein said tubular configuration is provided with a substantially horizontally disposed bottom closure means, the improvement which comprises: elongated inclined hand hole means in each of a pair of opposed sidewall panels, said inclined hand hole means being located intermediate the height and width of said sidewall panels, said inclined hand hole means comprising two pairs of substantially elongated slot-shaped hand hole cutouts, each elongated slot hand hole being defined by two substantially parallel, coextensive cut lines connected at their respective ends by continuous cut lines, one of said pair of slot-shaped hand holes being located on each of said opposed sidewall panels, each of said pairs of slot-shaped hand holes being placed on said opposed sidewall panels such that one of each pair is adjacent one of the foldable connections of said sidewall panel and the other of said pair is adjacent the other foldable connection of said sidewall panel, the extended longitudinal axes of all of said elongated slot-shaped hand holes intersecting the plane of said bottom closure means at an acute angle.
Claim 8
Dependent Claim
76 words
