Abstract
Abstract A telescoping container is formed by utilizing a one-piece corrugated paperboard blank which is scored and slotted in a predetermined pattern and severable into two blanks which are adapted to be folded into telescoping cover and body members. Longitudinal pairs of offset fold lines are formed in the blank by the use of male-to-male offset scoring heads on the corrugator. The blank is then scored to form fold lines in the transverse direction by the use of male-to-female or male-to-flat scoring heads. Two connected portions are thereby adapted to be separated from each other and folded to form matching cover and body members for a telescoping carton.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
275 words
A blank of foldable Material adapted to be separated into two portions which may be folded to form separate, complementary body and cover members of a telescopic container, said blank having a pair of outer longitudinal fold lines formed on a first side thereof and a pair of inwardly offset longitudinal fold lines formed on a second side thereof, said longitudinal fold lines terminating at the longitudinal extremities of said blank, a transverse separation means formed therein and terminating at the transverse extremities of said blank for separating the blank into bodyforming and cover-forming portions, opposed transverse slots extending inwardly at least to said inwardly offset longitudinal fold lines and interrupting the continuity of said outer longitudinal fold lines in the bodY-forming portion of said blank, transverse fold lines disposed intermediate the inner margins of said opposed transverse slots in said body-forming portion and formed on said second side of said blank, opposed transverse slots extending inwardly at least to said outer longitudinal fold lines in the cover-forming portion of said blank and transverse fold lines disposed intermediate the inner margins of said opposed transverse slots in said cover-forming portion and formed on said first side of said blank, whereby when said body-forming portion is separated from said cover-forming portion along said transverse separations means and is folded about said inwardly offset longitudinal fold lines and said transverse fold lines, respectively, on said second side of said blank a body member is formed, and when said cover-forming portion is folded about said outer longitudinal fold lines and said transverse fold lines, respectively, on said first side of said blank, a complementary cover member is formed.
Claim 2
Dependent Claim
275 words
A blank of foldable Material adapted to be separated into two portions which may be folded to form separate, complementary body and cover members of a telescopic container, said blank having a pair of outer longitudinal fold lines formed on a first side thereof and a pair of inwardly offset longitudinal fold lines formed on a second side thereof, said longitudinal fold lines terminating at the longitudinal extremities of said blank, a transverse separation means formed therein and terminating at the transverse extremities of said blank for separating the blank into bodyforming and cover-forming portions, opposed transverse slots extending inwardly at least to said inwardly offset longitudinal fold lines and interrupting the continuity of said outer longitudinal fold lines in the bodY-forming portion of said blank, transverse fold lines disposed intermediate the inner margins of said opposed transverse slots in said body-forming portion and formed on said second side of said blank, opposed transverse slots extending inwardly at least to said outer longitudinal fold lines in the cover-forming portion of said blank and transverse fold lines disposed intermediate the inner margins of said opposed transverse slots in said cover-forming portion and formed on said first side of said blank, whereby when said body-forming portion is separated from said cover-forming portion along said transverse separations means and is folded about said inwardly offset longitudinal fold lines and said transverse fold lines, respectively, on said second side of said blank a body member is formed, and when said cover-forming portion is folded about said outer longitudinal fold lines and said transverse fold lines, respectively, on said first side of said blank, a complementary cover member is formed.
Claim 3
Dependent Claim
23 words
A blank of foldable material as set forth in claim 1, wherein said transverse separation means is a slit formed in said blank.
Claim 4
Dependent Claim
269 words
A telescopic container including separate, complementary body and cover members, each of which is formed from the same blank of foldable material, said blank having a pair of outer longitudinal fold lines formed on a first side thereof and a pair of inwardly offset longitudinal fold lines formed on a second side thereof, said longitudinal fold lines terminating at the longitudinal extremities of said blank, a transverse separation means formed therein and terminating at the transverse extremities of said blank for separating the blank into body-forming and cover-forming portions, opposed transverse slots extending inwardly at least to said inwardly offset longitudinal fold lines and interrupting the continuity of said outer longitudinal fold lines in the body-forming portion of said blank, transverse fold lines disposed intermediate the inner margins of said opposed transverse slots in said body-forming portion and formed on said second side of said blank, opposed transverse slots extending inwardly at least to said outer longitudinal fold lines in the cover-forming portion of said blank and transverse fold lines disposed intermediate the inner margins of said opposed transverse slots in said cover-forming portion and formed on said first side of said blank, whereby when said body-forming portion is separated from said cover-forming portion along said transverse separation means and is folded about said inwardly offset longitudinal fold lines and said transverse fold lines respectively, on said second side of said blank, a body member is formed, and when said cover-forming portion is folded about said outer longitudinal fold lines and said transverse fold lines, respectively, on said first side of said blank, a complementary cover member is formed.
Claim 5
Dependent Claim
269 words
A telescopic container including separate, complementary body and cover members, each of which is formed from the same blank of foldable material, said blank having a pair of outer longitudinal fold lines formed on a first side thereof and a pair of inwardly offset longitudinal fold lines formed on a second side thereof, said longitudinal fold lines terminating at the longitudinal extremities of said blank, a transverse separation means formed therein and terminating at the transverse extremities of said blank for separating the blank into body-forming and cover-forming portions, opposed transverse slots extending inwardly at least to said inwardly offset longitudinal fold lines and interrupting the continuity of said outer longitudinal fold lines in the body-forming portion of said blank, transverse fold lines disposed intermediate the inner margins of said opposed transverse slots in said body-forming portion and formed on said second side of said blank, opposed transverse slots extending inwardly at least to said outer longitudinal fold lines in the cover-forming portion of said blank and transverse fold lines disposed intermediate the inner margins of said opposed transverse slots in said cover-forming portion and formed on said first side of said blank, whereby when said body-forming portion is separated from said cover-forming portion along said transverse separation means and is folded about said inwardly offset longitudinal fold lines and said transverse fold lines respectively, on said second side of said blank, a body member is formed, and when said cover-forming portion is folded about said outer longitudinal fold lines and said transverse fold lines, respectively, on said first side of said blank, a complementary cover member is formed.
Claim 6
Dependent Claim
21 words
A telescopic container as set forth in claim 3, wherein said transverse separation means is a slit formed in said blank.
