Abstract
Abstract A preferably corrugated cardboard, shock-absorbing carton insert completely surrounds a product except for the top which is open to display the product to view. The insert is made from a corrugated cardboard blank having preformed score and cut lines which enable the blank to fold into a generally rectangular box having enlarged end panels that support the box in a position which is spaced away from all adjacent structures. There is a V-shaped fold between the box and each of its end panels to provide greater rigidity and further strength. Tab ends are positioned between the box and the end panel to help absorb a shock in any direction. The corrugated cardboard automatically assumes a desired end-product configuration responsive to four simple folding motions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
149 words
A shock-absorbing carton insert made from a blank having score lines defining a central panel with matched sets of two pairs of opposed side panels and matched sets of two pairs of opposed end panels interconnected by four corner panels, each of said corner panels being defined by hinge-forming score lines which are not aligned with but are spaced between and parallel with score lines forming inner ones of both said matched pairs of side and end panels, whereby said matched pairs of side and end panels form a rectangular, box-like container when the side panels are articulated, the side and end panels being proportioned to fold along said score lines to form erected ends which are much wider than the erected sides in order for the ends to project above and below the box-like container and thereby provide a shock-absorbing quality for a product enclosed within the box.
Claim 2
Dependent Claim
149 words
A shock-absorbing carton insert made from a blank having score lines defining a central panel with matched sets of two pairs of opposed side panels and matched sets of two pairs of opposed end panels interconnected by four corner panels, each of said corner panels being defined by hinge-forming score lines which are not aligned with but are spaced between and parallel with score lines forming inner ones of both said matched pairs of side and end panels, whereby said matched pairs of side and end panels form a rectangular, box-like container when the side panels are articulated, the side and end panels being proportioned to fold along said score lines to form erected ends which are much wider than the erected sides in order for the ends to project above and below the box-like container and thereby provide a shock-absorbing quality for a product enclosed within the box.
Claim 3
Dependent Claim
87 words
The carton insert of claim 1 wherein the proportions of the various panels are such that when the insert is erected a V-fold is formed along the lower edge of the end panels to raise and support said central panel when in a fully erected position, the space within said V-fold forming an area of collapse which must crumple when the erected insert is subjected to a force in a direction which tends to collapse said V-fold before a product enclosed with the box-like container is damaged.
Claim 4
Dependent Claim
49 words
The carton insert of claim 1 wherein an opening is formed in said central panel for receiving a product enclosed within the box-like container forming said insert and tabs formed at the edges of said opening for providing a shock-absorbing quality and an orientation, indexing, locking, and stabilization function.
Claim 5
Dependent Claim
71 words
The carton insert of claim 1 and cut lines between a limited portion of the interconnection of said corner panels, said cut lines forming an angle when said insert is erected for holding the end panels spaced away from said box-like container without completely severing the interconnection in order to provide a shock-absorbing space within the erected insert which must crumple before a product contained within the box-like container is damaged.
Claim 6
Dependent Claim
21 words
The carton insert of claim 1 and a pair of locking tabs for holding said carton when in a folded position.
