Abstract

Abstract This disclosure relates to an egg carton or the like formed of a plurality of transverse pairs of pockets for receiving eggs, and a pair of covers for closing a body of the carton. Adjacent end panels of the covers are provided with concave, triangular recesses for facilitating the introduction of a person''s fingers between the covers to readily open the same. The carton is preferably of a molded pulp construction, and bottom walls of at least selected ones of the pairs of compartments are rigidified by a wall bridging a longitudinal centerline of the carton while other transverse pairs are spaced from one another by a gap across the centerline.

Claim 3
Dependent Claim 16 words
The carton as defined in claim 1 wherein said carton is of a molded pulp construction.
Claim 4
Dependent Claim 171 words
A carton comprising a carton body having a bottom wall, a pair of sidewalls and a pair of end walls, at least a pair of covers for opening and closing an end of said carton body opposite said bottom wall, each of said covers including a top panel, a pair of side panels and a pair of end panels, one of said side panels being hingeably connected to an associated one of each of said sidewalls, the others of said side panels being in generally opposed relationship along a longitudinal centerline of said body, a connecting panel between one of said other side panels and an adjacent one of said end panels, said connecting panel including means for facilitating the introduction of a person''s finger between said pair of covers and the subsequent opening thereof whereby access to the interior of the carton body and articles therein is effected rapidly and efficiently, and said facilitating means is a generally triangularly shaped wall of said connecting panel converging toward said top panel.
Claim 5
Dependent Claim 171 words
A carton comprising a carton body having a bottom wall, a pair of sidewalls and a pair of end walls, at least a pair of covers for opening and closing an end of said carton body opposite said bottom wall, each of said covers including a top panel, a pair of side panels and a pair of end panels, one of said side panels being hingeably connected to an associated one of each of said sidewalls, the others of said side panels being in generally opposed relationship along a longitudinal centerline of said body, a connecting panel between one of said other side panels and an adjacent one of said end panels, said connecting panel including means for facilitating the introduction of a person''s finger between said pair of covers and the subsequent opening thereof whereby access to the interior of the carton body and articles therein is effected rapidly and efficiently, and said facilitating means is a generally triangularly shaped wall of said connecting panel converging toward said top panel.

Dependent Claim 26 words
The carton as defined in claim 3 wherein said facilitating means is a generally outwardly opening concave recess defined by a wall of said connecting panel.
Claim 7
Dependent Claim 250 words
A carton coMprising a carton body having a bottom wall, a pair of sidewalls and a pair of end walls, at least a pair of covers for opening and closing an end of said carton body opposite said bottom wall, each of said covers including a top panel, a pair of side panels and a pair of end panels, one of said side panels being hingeably connected to an associated one of each of said sidewalls, the others of said side panels being in generally opposed relationship along a longitudinal centerline of said body, a connecting panel between one of said other side panels and an adjacent one of said end panels, said connecting panel including means for facilitating the introduction of a person''s finger between said pair of covers and the subsequent opening thereof whereby access to the interior of the carton body and articles therein is effected rapidly and efficiently, and said body is divided into a plurality of pairs of generally cup-shaped article receiving compartments with a compartment of each pair of compartments being disposed on opposite sides of a centerline of said body, said compartments each having end body wall portions terminating in respective bottom walls, the end body wall portions of at least one of said pair of compartments being connected to each other across said centerline, and the end body wall portion of at least another of said pair of compartments being unconnected and spaced from one another by a gap across said centerline.
Claim 8
Dependent Claim 250 words
A carton coMprising a carton body having a bottom wall, a pair of sidewalls and a pair of end walls, at least a pair of covers for opening and closing an end of said carton body opposite said bottom wall, each of said covers including a top panel, a pair of side panels and a pair of end panels, one of said side panels being hingeably connected to an associated one of each of said sidewalls, the others of said side panels being in generally opposed relationship along a longitudinal centerline of said body, a connecting panel between one of said other side panels and an adjacent one of said end panels, said connecting panel including means for facilitating the introduction of a person''s finger between said pair of covers and the subsequent opening thereof whereby access to the interior of the carton body and articles therein is effected rapidly and efficiently, and said body is divided into a plurality of pairs of generally cup-shaped article receiving compartments with a compartment of each pair of compartments being disposed on opposite sides of a centerline of said body, said compartments each having end body wall portions terminating in respective bottom walls, the end body wall portions of at least one of said pair of compartments being connected to each other across said centerline, and the end body wall portion of at least another of said pair of compartments being unconnected and spaced from one another by a gap across said centerline.
Claim 9
Dependent Claim 49 words
