Claim 3

A shock-proof packing container as claimed in claim 1, wherein the flexible sling is attached to and suspended between the end walls of the inner support member.

Claim 4

A packing container as claimed in claim 2, wherein: the end walls and the locking flaps have openings adjacent the midpoints thereof such that the locking flaps and end wall openings mate when the locking flaps are placed over the end walls, thereby forming a single opening through each end of the inner support member; and the ends of the flexible sling extend through the respective openings in the ends of the inner support member and are fastened to the inner support member.

Claim 5

A container as claimed in claim 3 wherein the flexible sling comprises a polyethylene wrapper in which the fragile article is wrapped, and the ends of the polyethylene wrapper are extended through the openings in the end walls of the interior support member and are folded over the top of the interior support member and are stapled thereto.

Claim 6

A shock-proof packing container as claimed in claim 1 wherein the inner support member is formed from a single flat piece of packing material.

Claim 7

A shock-proof packing container as claimned in claim 5 wherein the inner support member is formed from a single, flat corrugated cardboard blank, said blank comprising an elongated rectangular member which is provided with transverse score lines, so that the piece may be folded in order to form the polygonal inner support member, said blank further comprising two rectangular tabs attached to the long side of the elongated rectangular member along the portions thereof that form the upper edges of the end walls of the inner support member, said blank being scored along the lines of attachment of the tabs to the elongated rectangular member so that the tabs are bendable downwardly over the end walls in order to form locking flaps.

Claim 8

A shock-proof packing container for shipping fragile articles comprising: a rectangular outer carton having two end walls and two side walls; an inner support means adapted to fit snugly within said outer carton, said inner support means comprising a channel-shaped member having at least six sides, with said channel-shaped member comprising two opposing end walls that abut the end walls of the outer carton and side walls which extend outwardly into contact with the respective side walls of the outer carton adjacent the midpoints thereof, said inner support member further comprising locking flaps attached to each of the end walls thereof, said locking flaps being interposed between the end walls of the inner support member and the outer carton and extending outwardly from the inner support member into contact with the side walls of the outer carton, thereby holding the end walls of the inner support means in a fixed position with respect to the end walls of the packing container; and a flexible sling means attached to two opposing walls of the interior support means, said flexible sling means being adapted to envelop and hold fragile articles in suspension in the interior of the container.

Claim 9

A shock-proof packing container for shipping fragile articles comprising: a rectangular outer carton having two end walls and two side walls; an inner support means adapted to fit snugly within said outer carton, said inner support means comprising a channel-shaped member having at least six sides, with said channel-shaped member comprising two opposing end walls that abut the end walls of the outer carton and side walls which extend outwardly into contact with the respective side walls of the outer carton adjacent the midpoints thereof, said inner support member further comprising locking flaps attached to each of the end walls thereof, said locking flaps being interposed between the end walls of the inner support member and the outer carton and extending outwardly from the inner support member into contact with the side walls of the outer carton, thereby holding the end walls of the inner support means in a fixed position with respect to the end walls of the packing container; and a flexible sling means attached to two opposing walls of the interior support means, said flexible sling means being adapted to envelop and hold fragile articles in suspension in the interior of the container.

Claim 10

A shock-proof packing container as claimed in claim 7, wherein: the inner support member is hexagonal; and the flexible sling is attached to and suspended between the end walls of The inner support member.

Claim 11

A packing container as claimed in claim 8, wherein the inner support member is formed of a single sheet of flat packing material, said sheet comprising an elongated rectangular member having transverse score lines so that the member may be folded in order to form the hexagonal inner support member, said sheet further comprising rectangular tabs attached to the long side of the elongated rectangular member along the upper edge of the portion of the elongated rectangular sheet that forms the end walls of the inner support member. whereby, the channel-shaped member may be formed by folding the elongated rectangular sheet in order to form the hexagonal inner support member and then folding the tabs downwardly over the end walls of the inner support means in order to form locking flaps.

Claim 12

A shock-proof packing container for packing fragile articles comprising: a rectangular outer carton having two vertical end walls, two vertical side walls, and a top and a bottom, the top of which comprises flaps that may be opened or closed; an inner support member adapted to fit snugly within the outer carton, said inner support member comprising: a six-sided channel-shaped member having closed vertical sides and an open top and bottom, the sides of said channel-shaped member being equal to the height of the sides of the outer carton and comprising two opposing end walls that are narrower than and abut the end walls of the outer carton, said sides of said channel-shaped member further comprising four side walls that extend outwardly from the end walls of the inner support member and bear against the side walls of the outer carton adjacent the midpoints thereof; and locking flaps attached to the end walls of the inner support member and interposed between the respective end walls of the inner support member and the outer carton, said locking flaps extending outwardly so as to bear against the side walls of the outer carton, thereby maintaining the end walls of the inner support member in a fixed transverse position relative to the end walls of the outer carton; and a flexible sling comprising a plastic wrapper wherein fragile articles to be shipped are securely wrapped, the ends of the flexible sling being extended respectively through openings formed in the end walls and locking flaps of the inner support member and being drawn tightly over the top edge of the end walls and stapled thereto.

Claim 13

A shock-proof packing container for packing fragile articles comprising: a rectangular outer carton having two vertical end walls, two vertical side walls, and a top and a bottom, the top of which comprises flaps that may be opened or closed; an inner support member adapted to fit snugly within the outer carton, said inner support member comprising: a six-sided channel-shaped member having closed vertical sides and an open top and bottom, the sides of said channel-shaped member being equal to the height of the sides of the outer carton and comprising two opposing end walls that are narrower than and abut the end walls of the outer carton, said sides of said channel-shaped member further comprising four side walls that extend outwardly from the end walls of the inner support member and bear against the side walls of the outer carton adjacent the midpoints thereof; and locking flaps attached to the end walls of the inner support member and interposed between the respective end walls of the inner support member and the outer carton, said locking flaps extending outwardly so as to bear against the side walls of the outer carton, thereby maintaining the end walls of the inner support member in a fixed transverse position relative to the end walls of the outer carton; and a flexible sling comprising a plastic wrapper wherein fragile articles to be shipped are securely wrapped, the ends of the flexible sling being extended respectively through openings formed in the end walls and locking flaps of the inner support member and being drawn tightly over the top edge of the end walls and stapled thereto.
