Abstract
Abstract A unitary molded packing element used in packing cases for fragile articles such as fluorescent light tubes in which the packing element comprises a plurality of mutually parallel, elongated arcuate sockets defined by apertured coplanar ribs; in which outer side margins and end margins are defined by hollow, triangular elements which are relatively strong in compression and permit both longitudinal and transverse flexure of the packing elements; and in which the separator elements include notched tabs which are interlockable when in inverted pairs.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
183 words
A unitary packing element of molded material for separating and protecting the ends of a plurality of elongated cylindrical tubes in a package, the packing element comprising: a sheet having a plurality of mutually parallel articlereceiving sockets having an arcuate cross section; said sheet including an end and opposed side walls extending vertically from a base, said end wall comprising a plurality of hollow, triangular segments closed towards its socket and opening outwardly therefrom, each socket having a pair of triangular segments facing one end of each socket and a valley portion therebetween terminating at the base of the sockets, said side walls each comprising a plurality of hollow triangular segments opening outwardly from the endmost sockets including an arcuate inner wall forming a fragmentary portion of an adjacent socket, said socket comprising an arcuate base terminating in a plurality of hollow, intermediate rib segments, parallel to said side walls, said intermediate ribs being in alignment with a valley between each second pair of triangular segments in said end wall, said sockets having a free end opening away from the said end wall.
Claim 2
Dependent Claim
183 words
A unitary packing element of molded material for separating and protecting the ends of a plurality of elongated cylindrical tubes in a package, the packing element comprising: a sheet having a plurality of mutually parallel articlereceiving sockets having an arcuate cross section; said sheet including an end and opposed side walls extending vertically from a base, said end wall comprising a plurality of hollow, triangular segments closed towards its socket and opening outwardly therefrom, each socket having a pair of triangular segments facing one end of each socket and a valley portion therebetween terminating at the base of the sockets, said side walls each comprising a plurality of hollow triangular segments opening outwardly from the endmost sockets including an arcuate inner wall forming a fragmentary portion of an adjacent socket, said socket comprising an arcuate base terminating in a plurality of hollow, intermediate rib segments, parallel to said side walls, said intermediate ribs being in alignment with a valley between each second pair of triangular segments in said end wall, said sockets having a free end opening away from the said end wall.
Claim 3
Dependent Claim
44 words
The structure as claimed in claim 1 in which said intermediate rib segments generally comprise a hollow triangular element having arcuate sides opening into respective adjacent sockets, at least one of said sides having an opening forming a relatively thin flexible upper terminal lip.
Claim 4
Dependent Claim
35 words
The structure as claimed in claim 2 in which said thin flexible upper terminal lips are notched whereby an inverted packing element will interlock with an underlying element to enclose a flexible element being protected.
Claim 5
Dependent Claim
29 words
The structure as claimed in claim 5 in which said terminal lips project above the uppermost portion of said triangular segments and are aligned with a lower notch portion.
Claim 6
Dependent Claim
31 words
The structure as claimed in claim 1 which pairs of vertically extending segments of said side walls are coplanar with the plane passing through corresponding walls of said intermediate rib segments.
Claim 7
Dependent Claim
27 words
The structure as claimed in claim 1 in which said side end walls are relatively rigid but permit both longitudinal and transverse flexure of said packing element.
Claim 8
Dependent Claim
44 words
The structure as claimed in claim 1 in which said intermediate rib segments generally comprise a hollow triangular element having arcuate sides opening into respective adjacent sockets, at least one of said sides having a plurality of tab cushion shock absorbing members formed thereon.
Claim 9
Dependent Claim
22 words
The structure as claimed in claim 1 in which said sockets have a plurality of pocket cushioning shock absorbing members formed therein.
