Packaging method and construction

Claim 2

A packaging assembly for containment and protection of an article comprising a carton having side walls and at least one open end operable to be closed by flaps formed integrally with at least some of the walls, a support structure inserted in said carton, said structure having means securing an article thereto and at least one locking element extending therefrom, and one carton flap being folded upon itself to embrace said locking element in reverse fold relationship thereby retaining said support structure against movement in said carton.

Claim 3

A packaging assembly for containment and protection of an article, comprising a carton having side walls and opposite open ends operable to be closed by flaps formed integrally with at least some of said walls, a support structure inserted in said carton, said structure having means securing an article thereto and locking elements extending therefrom, and one carton flap for each open end being folded upon itself to embrace a locking element thereby retaining said support structure against movement in said carton.

Claim 4

A packaging assembly for containment and protection of an article, comprising a carton having side walls and opposite open ends operable to be closed by flaps formed integrally with at least some of said walls, a support structure inserted in said carton, said structure having means securing an article thereto and locking elements extending therefrom, and one carton flap for each open end being folded upon itself to embrace a locking element thereby retaining said support structure against movement in said carton.

Claim 5

The assembly of claim 1 wherein said support structure comprises an integral sheet of relatively firm material having portions folded to form spacer elements spacing the bulk of said structure from one side of said carton and tabs folded to engage edges of said article to hold same against a face of said structure facing away from said one side toward an opposite side of said carton.

Claim 6

The assembly of claim 3 and including means clamping said tabs on said article edges.

Claim 7

The assembly of claim 1 wherein a second carton flap in its closed position overlies a portion at least of said one carton flap embracing said locking element whereby said flaps and said locking element are at least in part coextensive for stapling together.

Claim 8

The assembly of claim 1 wherein said one carton flap extends from a carton side wall at one open end, and being inwardly folded on a longitudinal line spaced between the flap outer extremity and the carton open end to embrace said locking element, the flap outer extermity thereby urging said locking element toward a side of said carton.

Claim 9

The assembly of claim 6 wherein said one carton flap in its folded position has its outer extremity in abutment with said locking element for holding it firmly into the juncture of said carton side wall and said flap.

Claim 10

The assembly of claim 1 wherein the carton and support structure each are formed of corrugated paperboard material.

Claim 11

A packing assembly for containment and protection of an article, comprising: a carton having side walls and opposite open ends closeable by flaps formed integrally with at least some of said walls, a support structure inserted in said carton and formed of an integral sheet of relatively firm material having portions folded to form on one side of said sheet spacer elements spacing the bulk of said carton and tabs folded to engage edges of said article to hold same against the other side of said sheet and spaced from all sides of said carton, at least one carton flap and said support structure sheet having respectively integral elements coacting in reverse fold relationship with each other upon closing said carton ends to retain said structure in substantially immovable position within said carton, said spacer elements comprising triangular tubes each having on edge facing one side carton, such tube edges having means for crushing under impact to absorb the shock thereof, said means comprising a scallop shape provided on each of said tube edges to progressively absorb and resist the energy of impact crushing said tube edges.

Claim 12

A packing assembly for containment and protection of an article, comprising: a carton having side walls and opposite open ends closeable by flaps formed integrally with at least some of said walls, a support structure inserted in said carton and formed of an integral sheet of relatively firm material having portions folded to form on one side of said sheet spacer elements spacing the bulk of said carton and tabs folded to engage edges of said article to hold same against the other side of said sheet and spaced from all sides of said carton, at least one carton flap and said support structure sheet having respectively integral elements coacting in reverse fold relationship with each other upon closing said carton ends to retain said structure in substantially immovable position within said carton, said spacer elements comprising triangular tubes each having on edge facing one side carton, such tube edges having means for crushing under impact to absorb the shock thereof, said means comprising a scallop shape provided on each of said tube edges to progressively absorb and resist the energy of impact crushing said tube edges.
