Package structure

Claim 2

A folding one-piece package structure comprising a pair of rectangular body portions each having four edges and an inside side and an outside side, each of the edges of each body portion converging from the outside side toward the inside side, recesses in each body portion extending from the inside side toward the outside side for receiving articles to be packaged, a hinge portion extending longitudinally of adjacent one edges of the body portions and connected thereto by an integral flexible hinge, said hinge portion having a triangular cross section, and triangular end parts for imparting rigidity to the hinge portion inclined toward each other and from the outside side toward the inside side of the body portions at substantially the same angle as the two edges of the body portions perpendicular to the one edges thereof and adjacent thereto are and inclined toward the inside side of the body portions, said inclined one edge of each of the body portions and said hinge structure effecting a 90* corner at each one edge of the body portions with the body portions positioned over each other by folding the one-piece package structure at the two flexible hinges and placing the inside sides of the body portions in surface to surface contact with each other.

Claim 3

Structure as set forth in claim 1 and further including means integral with the package structure for securing the body portions of the package structure together with the inside sides of the body portions in surface-to-surface contact.

Claim 4

Structure as set forth in claim 2 wherein the recesses in each of the body portions include a first annular recess extending from the inside side toward the outside side of the body portions and a second circular recess concentric with the annular recess and of smaller diameter than the inner diameter of the annular recess extending from the inside side of the body portions to the outside side of the body portions and generally triangular recesses extending from the inside sides of the body portions toward the outside sides thereof at each of the corners of the body portions and extending into the annular recesses whereby on placing the inside sides of the pair of body portions in surface-to-surface contact the annular recess and triangular recesses form a first compartment for a first article and the circular recess forms a second compartment for another article.

Claim 5

Structure as set forth in claim 2 wherein the means for securing the body portions of the package structure together with the inside sides of the body portions in surface-to-surface contact comprises a recess adjacent one of said two edges and a nipple adjacent the other of said two edges on one body portion and a recess adjacent the other of the two edges on the other of said body portions and a nipple adjacent the one of said two edges on the other of said body portions with the nipples and recesses in the two body portions being aligned so that the recesses receive the nipples with the inside sides of the body portions in surface-to-surface engagement, said nipples being of slightly larger diameter than said recesses to provide a snap fit of the nipples within the recesses whereby the body portions are retained in a position with the inside sides in surface-to-surface contact.

Claim 6

A folding one-piece package structure comprising a pair of rectangular body portions each having four edges and an inside side and an outside side, each of the edges of each body portion converging from the outside side toward the inside side, recesses in each body portion extending from the inside side toward the outside side for receiving articles to be packaged including a first annular recess extending from the inside side toward the outside side of the body portions and A second circular recess concentric with the annular recess and of smaller diameter than the inner diameter of the annular recess extending from the inside side of the body portions to the outside side of the body portions and generally triangular recesses extending from the inside sides of the body portions toward the outside sides thereof at each of the corners of the body portions and extending into the annular recesses whereby on placing the inside sides of the pair of body portions in a surface-to-surface contact the annular recess and triangular recesses form a first compartment for a first article and the circular recess forms a second compartment for another article, a hinge portion extending longitudinally of adjacent one edges of the body portions and connected thereto by an integral flexible hinge, said hinge portion having a triangular cross section, and triangular end parts for imparting rigidity to the hinge portion inclined toward each other and from the outside side toward the inside side of the body portions at substantially the same angle as the two edges of the body portions perpendicular to the one edges thereof and adjacent thereto are and inclined toward the inside side of the body portions, said inclined one edge of each of the body portions and said hinge structure effecting a 90* corner at each one edge of the body portions with the body portions positioned over each other by folding the one-piece package structure at the two flexible hinges and placing the inside sides of the body portions in surface-to-surface contact with each other, and means integral with the package structure for securing the body portions of the package structure together with the inside sides of the body portions in surface-to-surface contact including a recess adjacent one of said two edges and a nipple adjacent the other of said two edges on one body portion and a recess adjacent the other of the two edges on the other of said body portions and a nipple adjacent the one of said two edges on the other of said body portions with the nipples and recesses in the two body portions being aligned so that the recesses receive the nipples with the inside sides of the body portions in surface-to-surface engagement, said nipples being of slightly larger diameter than said recesses to provide a snap fit of the nipples within the recesses whereby the body portions are retained in a position with the inside sides in surface to surface contact.

Claim 7

A folding one-piece package structure comprising a pair of rectangular body portions each having four edges and an inside side and an outside side, each of the edges of each body portion converging from the outside side toward the inside side, recesses in each body portion extending from the inside side toward the outside side for receiving articles to be packaged including a first annular recess extending from the inside side toward the outside side of the body portions and A second circular recess concentric with the annular recess and of smaller diameter than the inner diameter of the annular recess extending from the inside side of the body portions to the outside side of the body portions and generally triangular recesses extending from the inside sides of the body portions toward the outside sides thereof at each of the corners of the body portions and extending into the annular recesses whereby on placing the inside sides of the pair of body portions in a surface-to-surface contact the annular recess and triangular recesses form a first compartment for a first article and the circular recess forms a second compartment for another article, a hinge portion extending longitudinally of adjacent one edges of the body portions and connected thereto by an integral flexible hinge, said hinge portion having a triangular cross section, and triangular end parts for imparting rigidity to the hinge portion inclined toward each other and from the outside side toward the inside side of the body portions at substantially the same angle as the two edges of the body portions perpendicular to the one edges thereof and adjacent thereto are and inclined toward the inside side of the body portions, said inclined one edge of each of the body portions and said hinge structure effecting a 90* corner at each one edge of the body portions with the body portions positioned over each other by folding the one-piece package structure at the two flexible hinges and placing the inside sides of the body portions in surface-to-surface contact with each other, and means integral with the package structure for securing the body portions of the package structure together with the inside sides of the body portions in surface-to-surface contact including a recess adjacent one of said two edges and a nipple adjacent the other of said two edges on one body portion and a recess adjacent the other of the two edges on the other of said body portions and a nipple adjacent the one of said two edges on the other of said body portions with the nipples and recesses in the two body portions being aligned so that the recesses receive the nipples with the inside sides of the body portions in surface-to-surface engagement, said nipples being of slightly larger diameter than said recesses to provide a snap fit of the nipples within the recesses whereby the body portions are retained in a position with the inside sides in surface to surface contact.
