Abstract
Abstract A box for holding carbon paper is made in two sections connected by a tear strip. The two sections are identical. Each has an integral pocket formed by flaps at the two ends and along one side of the base portion of the section. A plurality of carbon sheets can be held in each pocket. In use, the two sections are separated from one another by tearing away the connecting tear strip; and both sections can then be stored on the tilted partitions of a typist''s desk drawer for ready access to and return of the carbon sheets to the box section.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
128 words
A box for holding carbon paper comprising: two sections connected by a tear strip; each section comprising a rectangular base portion, two parallel sidewalls projecting perpendicularly above two parallel marginal edges of the base portion of the section, a sidewall projecting perpendicularly above one of the other two marginal edges of the base portion, and frame portions extending from said sidewalls part way only over said base portion to form with said sidewalls and base portion a pocket for holding carbon paper, which pocket is open along the fourth marginal edge of the base portion; and said tear strip connecting the two sections along said fourth marginal edge of the two base portions, whereby removal of said tear strip leaves two separate containers, each for holding carbon paper.
Claim 2
Dependent Claim
128 words
A box for holding carbon paper comprising: two sections connected by a tear strip; each section comprising a rectangular base portion, two parallel sidewalls projecting perpendicularly above two parallel marginal edges of the base portion of the section, a sidewall projecting perpendicularly above one of the other two marginal edges of the base portion, and frame portions extending from said sidewalls part way only over said base portion to form with said sidewalls and base portion a pocket for holding carbon paper, which pocket is open along the fourth marginal edge of the base portion; and said tear strip connecting the two sections along said fourth marginal edge of the two base portions, whereby removal of said tear strip leaves two separate containers, each for holding carbon paper.
Claim 3
Dependent Claim
168 words
A box for holding carbon paper comprising: a single sheet scored intermediate its ends along two parallel lines to form two sections and a tear strip connecting the two sections; each section having a base portion of generally rectangular shape and being folded upwardly along two parallel marginal side edges of its base portion and along a third marginal edge thereof remote from the tear strip to provide two parallel sidewalls connected by a third wall remote from said tear strip; each sidewall being folded to form a flap thereon overlying only the parts of the base portion of the respective section, which are adjacent the respective marginal edges thereof whereby said sidewalls and flaps form with the base portion of each section a pocket open at the fourth marginal edge of the respective section; and said tear strip connecting the two sections along these fourth marginal edges of the two base portions, whereby removal of the tear strip leaves two separate containers, each for holding carbon paper.
Claim 4
Dependent Claim
168 words
A box for holding carbon paper comprising: a single sheet scored intermediate its ends along two parallel lines to form two sections and a tear strip connecting the two sections; each section having a base portion of generally rectangular shape and being folded upwardly along two parallel marginal side edges of its base portion and along a third marginal edge thereof remote from the tear strip to provide two parallel sidewalls connected by a third wall remote from said tear strip; each sidewall being folded to form a flap thereon overlying only the parts of the base portion of the respective section, which are adjacent the respective marginal edges thereof whereby said sidewalls and flaps form with the base portion of each section a pocket open at the fourth marginal edge of the respective section; and said tear strip connecting the two sections along these fourth marginal edges of the two base portions, whereby removal of the tear strip leaves two separate containers, each for holding carbon paper.
Claim 5
Dependent Claim
90 words
A box as claimed in claim 2, wherein: the flaps on the two parallel sidewalls of a section are parallel to one another and disposed at opposite ends of perpendicular to, the other flap of the section; each of the two parallel flaps of a section has a generally triangular portion at the end remote from the perpendicular flap; and the triangular portions of the two sections being connected to their respective flaps along score lines so that the triangular portions may be bent under the section or torn away.
