Abstract

Abstract An improved packaging blank for contiguously aligned taco shells is provided with at least one holding member that frictionally engages the opposing interior surfaces of one shell. The holding member has serrated edges that include contact points. Perforations are also provided in the holding member to provide a resilient character to the serrated edges. A bottom member interfaces the exterior surface of another shell to assist in maintaining the shells in a position within the blank.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 293 words
An improved packaging blank for taco shells, each shell being brittle and similarly configured and dimensioned, the shells being contiguously aligned to each other by having the interior surface of each shell disposed about the exterior surface of the adjacent shell, the improvement comprising: a base panel for supporting the shells along a plane; a top panel extending from the base panel and having a planar surface that can be positioned perpendicular to a first axis; a bottom panel extending from the base panel and having a planar surface that can be positioned perpendicular to the first axis; a pair of side panels extending from the base panel, each side panel having a planar surface that can be positioned perpendicular to a second axis that is perpendicular to the first axis, the planar surfaces capable of remaining in contact with the edges of the shells; first means fixed to the planar surface of the top panel for maintaining the shells in a position along the base panel by operatively engaging the opposing interior surfaces of a first shell that interfaces the top panel, the first means including at least a first holding member having perforations and resilient, serrated opposing edge surfaces that are configured and dimensioned to extend along the interior surfaces of the first shell without contacting the bottom portion thereof particularly upon forces external to the blank being applied along the first axis; and second means fixed to the planar surface of the bottom panel for maintaining the shells in a position along the base panel, the second means having a flat surface area that operatively interfaces an exterior surface of a second shell to contact such exterior surface upon forces external to the blank being applied along the first axis.
Claim 2
Dependent Claim 293 words
An improved packaging blank for taco shells, each shell being brittle and similarly configured and dimensioned, the shells being contiguously aligned to each other by having the interior surface of each shell disposed about the exterior surface of the adjacent shell, the improvement comprising: a base panel for supporting the shells along a plane; a top panel extending from the base panel and having a planar surface that can be positioned perpendicular to a first axis; a bottom panel extending from the base panel and having a planar surface that can be positioned perpendicular to the first axis; a pair of side panels extending from the base panel, each side panel having a planar surface that can be positioned perpendicular to a second axis that is perpendicular to the first axis, the planar surfaces capable of remaining in contact with the edges of the shells; first means fixed to the planar surface of the top panel for maintaining the shells in a position along the base panel by operatively engaging the opposing interior surfaces of a first shell that interfaces the top panel, the first means including at least a first holding member having perforations and resilient, serrated opposing edge surfaces that are configured and dimensioned to extend along the interior surfaces of the first shell without contacting the bottom portion thereof particularly upon forces external to the blank being applied along the first axis; and second means fixed to the planar surface of the bottom panel for maintaining the shells in a position along the base panel, the second means having a flat surface area that operatively interfaces an exterior surface of a second shell to contact such exterior surface upon forces external to the blank being applied along the first axis.
Claim 3
Dependent Claim 31 words
The invention of claim 1 wherein the first means includes a second holding member that can interface the first holding member and is configured and dimensioned like the first holding member.
Claim 4
Dependent Claim 17 words
The invention of claim 1 wherein second means comprises two planar surfaces positioned perpendicular to each other.
Claim 5
Dependent Claim 34 words
The invention of claim 1 wherein the top and bottom panels are each dimensioned with a surface length that is longer than the maximum length measured between the opposing interior surfaces of a shell.
Claim 6
Dependent Claim 49 words
The invention of claim 1 wherein the base panel has a generally rectangular configuration with a planar surface whose length is longer than that length defined by the aggregate of the shells being continguously aligned, the latter length being measured between the top and bottom portions of each shell.
Claim 7
Dependent Claim 30 words
The invention of claim 1 further comprising a lid member extending from the top panel that can be positioned adjacent to at least the top portion of the first shell.
