Abstract

Abstract An improved carton construction is disclosed. In the illustrated embodiment, it utilizes a top closure which folds over the top of the assembled carton, therebeing a matching closure on the opposite side to define a central opening for ventilating the fruit. Each top closure has appended at each end a curved skirt which terminates in a protruding tab. The tab inserts into a half circle opening, commonly called a half-thumb hole which is cut with an L-shaped cut, thereby securing the pair of top closures above a multiple thickness shoulder which gives strength to the end wall of the box for stacking.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 384 words
A carton for holding produce which is comprised of: (a) a sheet of cardboard of an appropriate gauge of thickness, the sheet folding into a bottom portion; (b) an end portion which stands upright relative to said bottom; (c) an attached side portion which is perpendicular to the end portion and to the bottom portion; (d) a lid portion appended to the side portion which folds over and covers the top of the box when assembled; (e) a lock tab affixed to a protruding skirt portion on said lid portion which inserts into an appropriately positioned locking slot cut in the end portion and wherein the lock tab extends towards the interior of the box upon insertion; (f) said end portion further includes a shoulder constructed of multiple layers of the cardboard; (g) wherein said end portion includes first and second parallel end portions which fold together into a double layer and which clamp between them a folded flap attached to the side portion to secure said side portion in position, and further including a shaped top edge on said end portion and conforming top edge on said folded flap; (h) wherein said folded flap has a bottom edge located against the bottom of the carton; (i) a locking slot in said bottom located to receive a protruding tab on said folding flap along the bottom edge thereof; (j) a cut and scored fold line between the first and second parallel end portions which forms a webbing across the top edge of said shoulder; (k) wherein said webbing defines a spacing between said first and second end portions to receive said folded flap between them as a means of capturing and holding them in relative position; (l) holes means formed in said parallel end portion and said folded flap which align to define an opening for lifting of the carton; (m) wherein said locking slot is an L-shaped cut into the exposed parallel end portion and said lock tab inserts therethrough and is frictionally grasped by said folded flap on insertion; and (n) wherein said L-shaped slot incorporates a top edge which is horizontal and which defines the bottom edge of a semicircular hole formed into said end portion, and said lock tab is formed into a tapered leading edge for ease of insertion.
Claim 2
Dependent Claim 384 words
A carton for holding produce which is comprised of: (a) a sheet of cardboard of an appropriate gauge of thickness, the sheet folding into a bottom portion; (b) an end portion which stands upright relative to said bottom; (c) an attached side portion which is perpendicular to the end portion and to the bottom portion; (d) a lid portion appended to the side portion which folds over and covers the top of the box when assembled; (e) a lock tab affixed to a protruding skirt portion on said lid portion which inserts into an appropriately positioned locking slot cut in the end portion and wherein the lock tab extends towards the interior of the box upon insertion; (f) said end portion further includes a shoulder constructed of multiple layers of the cardboard; (g) wherein said end portion includes first and second parallel end portions which fold together into a double layer and which clamp between them a folded flap attached to the side portion to secure said side portion in position, and further including a shaped top edge on said end portion and conforming top edge on said folded flap; (h) wherein said folded flap has a bottom edge located against the bottom of the carton; (i) a locking slot in said bottom located to receive a protruding tab on said folding flap along the bottom edge thereof; (j) a cut and scored fold line between the first and second parallel end portions which forms a webbing across the top edge of said shoulder; (k) wherein said webbing defines a spacing between said first and second end portions to receive said folded flap between them as a means of capturing and holding them in relative position; (l) holes means formed in said parallel end portion and said folded flap which align to define an opening for lifting of the carton; (m) wherein said locking slot is an L-shaped cut into the exposed parallel end portion and said lock tab inserts therethrough and is frictionally grasped by said folded flap on insertion; and (n) wherein said L-shaped slot incorporates a top edge which is horizontal and which defines the bottom edge of a semicircular hole formed into said end portion, and said lock tab is formed into a tapered leading edge for ease of insertion.
Claim 3
Dependent Claim 28 words
The apparatus of claim 1 wherein said lock tab includes parallel side edges defining a width less than the length of the top edge of said L-shaped slot.
