Abstract
Abstract This disclosure relates to cartons for packaging a plurality of individual tetrahedral articles and includes a carton body defined by a polygonally shaped bottom wall, opposite pairs of sidewalls, and opposite pairs of end walls, a closure panel is joined by a fold line to each sidewall with the closure panels being in a common plane parallel to the bottom wall in the closed position thereof, a medial panel is joined to each closure panel by a fold line with the medial panels being in side-by-side contiguous relationship generally parallel to a plane normal to the bottom wall, a terminal flap being joined to each medial panel along a fold line and being folded therealong into an outward and upward direction, and each terminal flap and its associated medial panel setting off an acute angle therebetween whereby the terminal flaps engage sides of the tetrahedral articles between the opposite transversely disposed seams thereof.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
200 words
A carton for packaging a plurality of tetrahedral articles having opposite transversely disposed end seams comprising a carton body defined by a generally polygonally shaped bottom wall having opposite pairs of side and end edges, an upstanding end wall joined to said bottom wall at each of the end edges thereof, an upstanding sidewall joined to said bottom wall at each of the side edges thereof, a closure panel joined to each sidewall along a fold line defining the uppermost edge of each sidewall, said closure panels lying in a common plane in spaced parallel relationship to said bottom wall, a medial panel joined to each closure panel by a fold line with said medial panels being in side-by-side contiguous relationship and generally parallel to a plane normal to said bottom wall, a terminal flap joined to each medial panel along a fold line and being folded therealong in an outward and upward direction, and each terminal flap and its associated medial panel setting off an acute angle therebetween whereby said terminal flaps are adapted to engage sides of tetrahedral articles between the opposite transversely disposed seams thereof thereby restraining the articles between the terminal flaps and the bottom wall.
Claim 2
Dependent Claim
200 words
A carton for packaging a plurality of tetrahedral articles having opposite transversely disposed end seams comprising a carton body defined by a generally polygonally shaped bottom wall having opposite pairs of side and end edges, an upstanding end wall joined to said bottom wall at each of the end edges thereof, an upstanding sidewall joined to said bottom wall at each of the side edges thereof, a closure panel joined to each sidewall along a fold line defining the uppermost edge of each sidewall, said closure panels lying in a common plane in spaced parallel relationship to said bottom wall, a medial panel joined to each closure panel by a fold line with said medial panels being in side-by-side contiguous relationship and generally parallel to a plane normal to said bottom wall, a terminal flap joined to each medial panel along a fold line and being folded therealong in an outward and upward direction, and each terminal flap and its associated medial panel setting off an acute angle therebetween whereby said terminal flaps are adapted to engage sides of tetrahedral articles between the opposite transversely disposed seams thereof thereby restraining the articles between the terminal flaps and the bottom wall.
Claim 3
Dependent Claim
75 words
The carton as defined in claim 1 including a plurality of tetrahedral articles packaged within said carton, said plurality of tetrahedral articles being arranged in two rows with one seam of each article being adjacent one of said sidewalls and the opposite seam of each respective article being adjacent the opposite sidewall and in upstanding relationship thereto, and each terminal flap being in contact with a sidewall of alternate tetrahedral article between the seams thereof.
